CITY OF LYNCHBURG | City of Lynchburg

INTRODUCTION Background The City of Lynchburg is an independent city of approximately 81,000 residents. The City encompasses 50 square miles situated along the James River at the foothill of the Blue Ridge Mountains. The entire City drains through a network of streams of seven major watersheds, to the James River which is a major tributary of the Chesapeake Bay. The headwaters of many of the City’s watersheds originate in the adjacent Bedford and Campbell Counties. The City has been a MS4 Phase 2 permittee since 2003. The Department of Water Resources (DWR) continues to coordinate compliance and works cooperatively with the many departments that share a role in the implementation of the program, including Community Development, Public Works, and Lynchburg City Schools. Since 2012, the City has implemented a stormwater utility to provide a dedicated funding source to support the stormwater management program and meeting multiple regulatory requirements. In addition to the City’s separate storm sewer system, a portion of the City is a combined system, in that both stormwater and wastewater are collected and discharged through the Lynchburg Water Resource Recovery Facility (LWRRF). These areas are not part of the MS4 area and are operated under the City’s Long-Term Control Plan (LTCP) and Consent Order rather than the City’s MS4 Permit.

In addition to the above program requirements, the most sigburgva.gov) nificant addition to the Plan is the two special conditions for We can also be reached at 434-455-4250 or the Chesapeake Bay TMDL and approved TMDLs other than stormwater@lynchburgva.gov Chesapeake Bay. Each special condition will result in the development of a TMDL Action Plan that will address the pollutants that that have been assigned a waste load allocation (WLA) to the MS4. The City initiated work on the Chesapeake Bay TMDL Action Plan during PY 1 to develop strategies for the required reductions in nitrogen, phosphorus and sediment. Future TMDL Action Plans will be required once the TMDLs have been approved. The City also has an approved James River Bacteria TMDL Action Plan that addresses bacteria as the pollutant of concern. The Bacteria TMDL Action Plan lists the strategies towards achieving bacteria reductions through outreach and education, and programmatic implementation of the MS4 Permit. Updates will be made to both Action Plans as required by the 2018-2023 Permit.

Part II B Special Conditions for TMDLs Other than the Chesapeake Bay In accordance with Part II B. Local TMDL special condition, the City has developed an approved TMDL Action Plan that addresses the strategies the City will undertake to meet the special condition requirements. The City received approval of the James River Bacteria TMDL Action Plan by DEQ on February 8, 2017. The Action Plan describes the best management practices the City will undertake to help reduce the amount of bacteria discharged from the MS4. Strategies in the Action Plan include public outreach and education on picking up pet waste and maintenance of septic systems, removal of straight pipe discharges, and reduction of illicit discharges. Separately from this Action Plan, the City is making significant upgrades to the LWRRF for additional reductions in overflows from the CSO areas of the City. These strategies together will help meet the waste load allocations in the TMDL.

Public Education and Outreach

DEPARTMENT(S) RESPONSIBLE: Water Resources PROPOSED ACTIONS: 1.1

Illicit Discharge Outreach & Education Objective and Expected Results: In Lynchburg the majority, approximately 96%, of the storm sewer collection systems carry runoff directly to local streams of the James River watershed. Therefore, it is important that we educate our citizens about the regulations guiding discharges into the storm sewers and the environmental harm of allowing pollutants such as chemicals, oil, and sediment to enter the storm systems. These are considered illicit discharges or non-stormwater discharges and therefore have been identified as a high-priority water quality issue. Implementation and Schedule: The “Only Rain Down the Drain” campaign seeks to raise awareness to the harm that commercial and residential illicit discharges cause to our local watersheds using tactics, language, and information that is specific to each. The City will implement two campaigns through the use of a combination of signage and written materials to communicate this message to the public. The ArtStormLYH storm drain contest will be one way the City will bring attention to this issue with outreach efforts ongoing throughout the year. The ArtStormLYH campaign is a stormwater drain mural contest in which the City partners with the James River Council for the Arts and Humanities to bring awareness to storm drains via unique, environmentally themed murals painted directly above the storm drains. Each storm drain also includes the statement, “Only Rain Down the Drain” and provides a community engagement opportunity. The City will also develop a campaign targeting commercial or non-residential enterprises such as car washes, pressure washers, landscape companies, or owners of recreational field facilities. This campaign will focus on providing written educational materials or training opportunities to commercial entities about illicit discharge regulations and how to prevent illicit discharges into the City’s storm system. The goal of these materials is to, first, prevent an illicit discharge, but, secondly, help provide education after an illicit discharge is reported. Documentation and Measure of Effectiveness: The City will track, annually, each campaign by documenting the reach of related social media messages, the number who participate in any associated outreach or celebration activities or businesses who have received outreach, the number of participants in any training or workshop events. 9

CITY OF LYNCHBURG | City of Lynchburg

1.2

Residential Homeowner Outreach Objective and Expected Results: Approximately 81,000 people call the City of Lynchburg home. Nonpoint source pollution like runoff from vehicle maintenance, lawn care, pet ownership, and de-icing greatly contribute to watershed degradation. The objective with the residential homeowner outreach campaign is to focus on the individual efforts that people can make to improve water quality in their daily activities as homeowners or renters and therefore has been identified as a highpriority water quality issue. Implementation and Schedule: The City will implement a residential homeowner campaign that will use at least one or a combination of signage, traditional written materials, media materials, or alternative materials. The residentially-focused campaign’s target audience is homeowners, renters, and property managers will focus on educating residents about the small, daily stormwater-friendly activities that can positively impact the health of the James River and its watershed. This may include information on stormwater runoff reduction practices, such as rain barrels, rain gardens, or buffers; information on lawn care best practices, such as keeping lawn clippings and autumn leaves out of storm drains; or proper application and disposal of pesticides/herbicides/fertilizers. The City will also develop an outreach effort to property owners that have swimming pools, including apartment complexes. Swimming pool discharges can have a negative environmental effect when not properly dechlorinated. This strategy will use a least one or a combination of traditional written materials or media materials to target messages to pool owners on ways to be environmentally friendly while staying cool in the summer time. The outreach efforts will be ongoing, throughout the year and seasonally appropriate so that they correspond to when the activities are most likely to occur. Documentation and Measure of Effectiveness: The City will summarize all activities, including examples of media developed, approximate audience reached through outreach efforts.

CITY OF LYNCHBURG | City of Lynchburg

1.3

Watershed Science Objective and Expected Results: The City of Lynchburg is part of the beautiful James River watershed that is also part of the Chesapeake Bay watershed. There are seven major watersheds across the City that includes the Blackwater Creek, Ivy Creek, Judith Creek, Fishing Creek, Tomahawk Creek, Dreaming Creek and several small creeks that drain straight to the James River. Educating our local community about the watershed in which they live, work, or play is important to maintain the overall health of these watersheds and therefore has been identified as a high-priority water quality issue. Implementation and Schedule: The City will implement a watershed education campaign through the use of written materials or community engagement that will empower students, teachers, and community members to be actively involved in caring for their water resources and to contribute to a healthy watershed for everyone in and downstream of Lynchburg. The Living in Your Watershed booklet is provided annually to all 4th graders in Lynchburg City Schools. The booklet provides written information about what is a watershed, ways of reducing pollution, and includes an interactive map of the City’s watersheds. Teachers are able to use this to create lessons and classroom activities to further reinforce SOL learning goals. Other outreach opportunities may include the use of the Enviroscape watershed model or interactive activities. The City will also implement this campaign through outreach and community engagements that may be achieved through speaking engagements or through City’s social media platforms. These engagements will focus on educating and empowering adults in the community to learn about and contribute to watershed health in Lynchburg. These engagements will occur on an ongoing basis or as requested by community groups. Documentation and Measure of Effectiveness: The City will track, on an annual basis, these campaigns by documenting how many print or digital materials are created and/or distributed/accessed, the number of website visitors, and the number of participants in each outreach event.

Public Involvement and Participation

DEPARTMENT(S) RESPONSIBLE: Water Resources, Public Works Parks & Rec, Communications & Marketing, Public Works PROPOSED ACTIONS: 2.1

Public notice and involvement Objective and Expected Results: The Department of Water Resources provides a website to host the MS4 Permit, Program Plan, Annual Reports, and associated documents for the public to view. The website also provides the opportunity for citizens to submit comments on the documents and appropriate staff will document and provide responses to comments received. The website also provides a mechanism for the public to report potential illicit discharges, improper disposal or spills to the MS4, complaints regarding land disturbance activities, or other potential stormwater concerns. Complaints will be forwarded to the appropriate department or division for follow-up. Implementation and Schedule: • The Department of Water Resources will host a webpage dedicated to making the MS4 Permit, Program Plan, and Annual Reports available to the public and to submit comments. • The TMDL Action Plans will be provided for public review and comment on the Department website. • The City will provide a 30 day public comment period prior to reapplication for future permits to seek comments on the MS4 program Plan. Documentation and Measure of Effectiveness: The City will provide documentation of press releases, a summary of public comments received on the draft MS4 Program Plan, and documentation that annual reports have been made available on the web page.

2.2

Promote and support volunteer activities Objective and Expected Results: The City is fortunate to have an active group of citizen volunteers that are willing to engage in stream clean-ups and other efforts to improve water quality. The City will continue to promote and support volunteer groups and opportunities. By fostering these volunteer relationships, we hope to gain a larger base of citizens who are engaged and can help promote the City’s stormwater messages and activities. Volunteer sponsored projects will be advertised through various City resources and communication outlets. City will participate in or sponsor at least four local activities within this permit cycle. Implementation and Schedule: Annually the City will participate in four local activities through promotion, sponsorship or other involvement. The City proposes the following activities: 1) Community or stream clean-up event(s) - The City will provide community clean up events aimed at keeping trash out of local streams or stream clean ups to remove trash or debris that have 12

CITY OF LYNCHBURG | City of Lynchburg

washed downstream. Events will generally be held between April through November, dependent on the weather conditions. The amount of material removed from these amounts will be tracked to document water quality improvement. 2) Storm Drain Marking – The City will provide opportunities for individuals and/or groups to mark storm drains to promote an Only Rain Down the Drain campaign. This will raise awareness to the harm that commercial and residential illicit discharges cause to our local waterways. The City may use a combination of approaches to do this from storm drain stenciling, installing medallions, or through the ArtStormLYN, a stormwater drain mural contest in which the City partners with the James River Council for the Arts and Humanities to bring awareness to storm drains via unique, environmentally themed murals painted directly above the storm drains. This opportunity will be provided annually or upon request from local volunteer groups. The City will track the number of storm drains marked, the number of submissions received, and number of people who participated. 3) BMP Educational Workshops – The City will provide at least one workshop each year to teach citizens how they can implement stormwater management practices on their property to reduce runoff and improve the overall health of the watershed. Workshop themes may include building rain barrels, benefits of rain gardens or composting, or vegetative buffers along streams. The City will track the number of participants in the workshop or reach through social media postings. 4) Household Hazardous Waste Collection – The City will promote the Hazardous Household and Electronic Waste recycling service and take back events. These events allow City residents, as well as regional localities, to bring back certain products or electronics for proper disposal or recycling. These events occur three times a year, generally in April, June, and October. Proper disposal of hazardous materials is important so that they are not improperly disposed of or discharged to the ground. The City will report on the number of residents that participated in the events and the amount of material that was received when the information is available. Documentation and Evaluation Criteria: The City will provide a summary of all programs that are supported, sponsored, and/or publicized by the City.

3.2

Prohibit non-stormwater discharges into the storm sewer system of the MS4 Objective and Expected Results: The Lynchburg City Code, specifically Section 16.2 Stormwater Management, Article VI, provides the legal authority to prohibit non-stormwater discharges to the City’s MS4. Implementation and Schedule: •

Implement and enforce City Code Section 16.2, Article VI.

•

Dry weather discharges will be investigated in accordance with the IDDE Standard Operating Procedures. Enforcement actions and legal penalties will be used for incidents of illicit discharge, when necessary, by the City. Education regarding this issue has proven to be an effective strategy and will be continued.

Documentation and Measure of Effectiveness: This has proven to be an effective means of regulating discharges to the City’s storm system. The City will document and track reported illicit discharges or illicit discharges during dry weather screening or through reported discharges.

3.3

Develop written procedures to detect, identify and address unauthorized non-stormwater discharges to the MS4 Objective and Expected Results: Written IDDE Standard Operating Procedure (SOP) outlines the responsibilities and procedures to inspect stormwater outfalls and other structures for illicit discharges. This document can be found in the Appendix 1. The SOP is applicable to City of Lynchburg employees assigned to inspect stormwater infrastructure for evidence of illicit discharges and will result in a consistent methodology to detect and address non-stormwater discharges. Implementation and Schedule: • Maintain a SOP that provides written procedures to detect identify and address non-stormwater discharges to the MS4 or illicit discharges. • Annually conduct outfall screenings of at least 50 outfalls per the program description in Part I E 3 c (2) b. • Continue to utilize the SOP document.

1.2 Safety Occupational Safety and Health Administration (OSHA) work safety standards, City SOPs, and other applicable guidelines should be followed in order to protect workers. Safety procedures must be followed by all inspection staff. Specific hazards which may be encountered include:  Exposure to hazardous wastes and materials,  Confined space, lifting and crushing hazards from stormwater and sanitary sewer infrastructure,  Exposure to chemicals and reagents used in water quality testing, and,  Exposure to traffic operations and environmental hazards.

1.2.1 Hazardous waste and materials Minimize contact and exposure to wastewaters, washwaters, hazardous materials and other substances encountered during incident response and dry weather screening. Combustible and toxic gases can collect in confined spaces or low-lying areas such as ditches.

IDDE Standard Operating Procedures

1.2.2 Stormwater and sanitary sewer infrastructure The following safety measures should be followed to avoid injury while opening manhole covers:  Bend knees, not waist. Use leg muscles instead of back muscles to lift the manhole cover.  Get firm footing and pull directly towards you. Do not twist your body. Know what is behind and to the side of you to avoid tripping hazards.  Wear steel toe boots to protect feet from crushing hazards.  Avoid using hands or fingers to move manhole covers. Use hooks in good condition. Do not enter manholes or pipes/outfalls under any circumstances. Confined space entry must only be done by properly trained and equipped persons.

1.2.3 Water quality testing kits The procedures and personal protective equipment (PPE) to be worn are described in greater detail in the appendices for each test, as listed in Table 1.2.  Minimize chemical exposures. Perform tests in well-ventilated area. Do not breathe vapors. Do not let chemicals touch your skin. Wear nitrile gloves and eye protection.  Follow test procedures carefully and observe all precautionary measures. Read the entire procedure carefully before beginning.  Use reagents and equipment only as directed by the test procedure.  Do not use damaged bottles or vials or broken equipment.  Have available and review Safety Data Sheets (SDS) for all reagents and standards.  Do not eat, drink or smoke in an area where chemicals are used.  Ensure portable eyewash unit in vehicle first aid kit is present and know how to use it.

2. Legal authorities The City’s municipal separate storm sewer system (MS4) is regulated by a permit (Permit) granted by the Virginia Department of Environmental Quality (VADEQ) under guidelines established in Phase II of the National Pollutant Discharge Elimination System (NPDES) program administered by the U.S. Environmental Protection Agency (USEPA). The Permit requires the City to prohibit unauthorized non-stormwater discharges into the MS4. The Permit requires the City to have a program and procedures to detect, identify, address, and effectively eliminate unauthorized non-stormwater discharges. The City prohibits unauthorized non-stormwater discharges into the storm sewer system through ordinance and standard operating procedures. The Permit is available at: http://www.lynchburgva.gov/stormwater-utilityms4-permit The Stormwater Pollution Control section (Article VI) is contained within the Stormwater Management (Chapter 16.2) ordinance, available at: https://library.municode.com/va/lynchburg/codes/code_of_ordinances?nodeId=CH16.2STMA_ARTVIST POCO Section 16.2-75 grants the program administrator and/or designees the authority to enter into private property to conduct inspection, surveillance and monitoring necessary to determine compliance and noncompliance with the stormwater pollution control ordinance. Per Section 16.2-75(c), no inspection shall be conducted without the consent of the tenant, occupant, property owner or the owner’s representative or pursuant to a duly issued administrative inspection warrant or as authorized by other lawful means. As noted in the Permit, the Commonwealth of Virginia allows non-stormwater discharges or flows listed in 9VAC25-890-20 D 3 to not be considered illicit discharges unless they are identified by the City as significant contributions of pollutants. The City maintains a similar list of exemptions in section 16.271(b).

IDDE Standard Operating Procedures

3. MS4 map and information tables The Permit requires the City to develop and maintain an accurate MS4 map and information table. The City uses three Geographic Information System (GIS) programs.  ESRI ArcGIS ArcMap – full-featured GIS  Lynchburg Map Viewer – internet and intranet based simplified GIS  ESRI Explorer for ArcGIS – cell phone accessible simplified GIS

4. Incident response and enforcement process The purpose of the incident response component of the IDDE program is to stop the discharge, minimize discharges and damage to the MS4 and surface waters, and require cleanup and proper disposal of the materials. The purpose of the enforcement process is to document observations and required actions, document whether cleanup and disposal has been performed, and initiate processes that may result in violations and penalties as outlined in Section 16.2-76 of the City ordinance.

4.1 Intake The City receives potential incident information from the following sources:  Lynchburg Emergency Communications – “Lyncom”  Stormwater hotline  Water Resources hotline  Direct reports to stormwater division staff  Direct observations by stormwater division staff

4.2 Triage The Stormwater Manager and/or Stormwater Inspector assign an informal degree of urgency to the reported incident to determine response urgency. These personnel also determine whether the response should be from Water Resources personnel or personnel from other departments or other agencies. The following guidelines may be helpful, but are not absolute, when doing triage. Immediate response warranted  Fire Department or Police Department requesting assistance  Active spills and leaks  Reports indicating impacts to surface waters  Reports indicating an active discharge to the MS4  Catastrophic drainage issues involving City infrastructure

IDDE Standard Operating Procedures

Less urgent response – respond to within 24 hours  Reports of vegetation dumped in stormwater system, if not being actively dumped  Reports of garbage and trash on a property or in a stormwater system  Reports of oil accumulation in parking spaces from leaking vehicles  Reports from City personnel or the public indicating a no longer active discharge  Drainage complaints if it is an ongoing issue

4.3 Incident response map Identifying sources and potential impacts is greatly assisted by maps of the stormwater and sanitary system, topography, and hydrology. Generating maps prior to response may not be practical in all cases, such as when an active discharge is observed by stormwater personnel when in the field. Map Viewer is the preferred method of generating response maps, although field use of ESRI Explorer for ArcGIS is acceptable in many cases. Be aware: maps generated by Map Viewer do not print stormwater outfall Facility ID (i.e, unique identifier) numbers. Stormwater manhole Facility ID numbers are printed. When possible, generate maps with the following information prior to going into the field.  Stormwater collection (e.g., Inlet, Outlet, Manhole, SW Gravity Main, BMP Point)  Sanitary sewer (e.g., Manhole, Gravity Main, Pressurized Main)  Hydrology (e.g., Rivers, Lakes and Ponds, Streams)  Elevation (e.g., Contours)  Standard Labels (e.g., Streets, Property Labels)  Property (e.g., Legal Lot Lines, Vacated Right of Way, Parcels, Easements)  Aerial photography

4.4 Incident scene processing The following are general guidelines that may be deviated from depending on the circumstances presented by an incident.  Approach an incident scene with caution. Personnel may be preoccupied with tasks and not alert to your approach. Activate emergency lights if warranted. Don personal protective equipment (PPE).  Assess the situation. Liquids and solids on the ground, roadways, and parking lots may be hazardous chemicals. Assess and take precautions for electrical, traffic, environmental, and other hazards.  Communicate presence on scene to lead emergency personnel or responsible party, if present. Determine type of chemical, quantity, hazard class, and other information.  Shut off source of chemicals/washwater, if possible.  Contain chemicals/washwater with berms and barriers. Clay dirt effectively contains most chemicals, while other materials such as oil dry, mulch, and booms can be considered.  Assess impact to stormwater system and surface waters. Deploy pads and booms as necessary. IDDE Standard Operating Procedures

   



 

Initiate source identification and tracing process, if necessary. See chapter 5.4. Collect and analyze samples from MS4, private stormwater systems, surface waters, and spill, if necessary. Be particularly cautious if chemical is unknown. Coordinate with incident command on scene. Initiate reporting to state agencies, if necessary. See chapter 4.6. Document with photographs and notes the arrival and departure times and actions of contractors, responsible parties, and City personnel. Document observations, actions, test results and names and contact information of responders and responsible parties. Take photographs of scene. While not required, it may be helpful to use the Stormwater Incident Report (SIR) form in appendix 1. Discuss and oversee necessary actions with emergency personnel, responsible party, and contractors. Actions may include additional containment, cleanup, abatement, removal and disposal of substances. See chapter 4.8. Initiate enforcement actions when necessary. See chapter4.9 for details. Assess need for assistance from other personnel. This may include, but not be limited to: o Water Resources – sewer overflows, CCTV inspections, laboratory analyses, o Public Works – cleanup assistance, road barricades, o Fire Department – major spill response, o Police Department – traffic control, management of hostile parties, o Community Development – construction site discharges, code compliance issues, broken sewer laterals.

4.5 Source identification At some incidents there are unknowns. This is particularly true when responding to reports of visual or olfactory oddities in surface waters or the MS4 with no readily obvious source. The source tracing components of chapter 5 are often effective when attempting to identify the source, but not the actual chemical, as part of an incident response. Most effective are windshield survey and bracketing survey techniques. These should be initiated immediately in order to track the residuals within a stormwater system if the discharge has ceased, and to eliminate the discharge as soon as possible if it is continuous. The screening methods in Chapter 5 are indicators of pollutants, and are not intended to identify and characterize industrial, construction, building maintenance or other strong chemicals. To identify unknown chemicals:  Field Observations are the most reliable indicator of substantial improper discharges. While they may not identify the particular chemicals involved, they are most useful for immediate source tracing (e.g. windshield survey and bracketing survey).  Field Measurements are the next most reliable indicators. Use pH paper - do not use the pH meter – when there is potential for strong chemicals. Damage to the pH meter may result. At a minimum, the pH bulb will need to be soaked and rinsed prior to future use if it is unintentionally exposed to strong acids or bases.

IDDE Standard Operating Procedures



Field Analyses may be conducted, with the understanding that they may not be effective if the as-yet-undetermined source is a strong chemical such as one would get from direct discharges, spills, or intentional dumping. These Field Analyses are designed to detect low concentrations of indicator chemicals commonly found in mixed waste streams, such as washwater and wastewater. The glassware for ammonia, fluoride and potassium tests will either need to be acid-washed or disposed of if exposed to strong chemicals.

The stormwater inspector does not possess the means for determining specific chemicals or categories of chemicals that may be present. The inspector will need to refer to additional resources and confer with the WWTP laboratory and contract laboratories about appropriate sampling and analyses on a case-by-case basis if chemical identification is required as part of an incident response.

4.6 Reporting to State agencies The following types of incidents should be reported to VADEQ and/or Virginia Department of Emergency Management (VDEM) as soon as possible:  Discharges affecting surface waters, going directly to Waters of the State (not going through MS4),  Discharges affecting surface waters, going through the MS4 to Waters of the State,  Discharges presenting severe threats to human health or the environment even if they do not affect surface waters. The following types of incidents should be reported to VADEQ within the annual report:  Discharges to the MS4 that do not reach Waters of the State,  Discharges contained and/or cleaned up before they can enter the MS4 or Waters of the State.

4.7 Documentation Each incident will be documented in the Illicit Discharge section of the Storm module of the COL Lucity database and asset management system. Incidents generate two types of media needing their own storage mechanism. Not every incident will generate both types of media.  Electronic media – photographs, videos, electronic forms, emails, etc., and,  Hardcopy media – forms, business cards, and manifests. Electronic media should be stored in a COL network folder unique to the incident. At present the COL storage is within the following directory structure, however, we have been informed by Information Technology that the directory structure is changing in the near future. The present directory structure is: “W:\MS4\MCMs\3 IDDE\Enforcement\FYxx\address – type of incident – date.” Efforts will be made to maintain a similar nomenclature in the new directory structure. Any paper media should be scanned and stored as an electronic file within the electronic media described above. Some paper media should also be maintained in hardcopy format. These include NOV,

IDDE Standard Operating Procedures

ORI, and SIR forms and waste disposal manifests. Other paper media may be scanned and then disposed of, such as incident response maps with location-identifying notations. Other paper media do not need to be scanned or stored if the information has been entered into the Lucity database, such as handwritten notes and business cards. Incident response maps that do not have notations do not need to be stored in any format. See chapter 7 for more data management and documentation information.

4.8 Cleanup, remediation and disposal City ordinance Section 16.2-76 gives the stormwater inspector authority to hold responsible parties “liable to the city for all costs of detecting, tracing, testing, containment, cleanup, abatement, removal, and disposal of any substance unlawfully discharged into the storm sewer system.” The stormwater inspector exercises discretion on what is required of responsible parties. The inspector evaluates the type of pollutant, quantity, impending weather, potential and actual damage, and disposal options. The following are general guidelines, which may be deviated from on a case-by-case basis due to circumstances:  Discharges that have not reached the MS4 or surface waters should be contained and cleaned up, usually with simple devices such as wet vacuums, and disposed of properly, often to the sanitary sewer. Other options for disposal must be exercised if the material could be hazardous.  Discharges to stormwater systems often depend on the waste, substrate, and structures involved. For example: o Low volumes of low-risk washwaters (e.g., mobile car wash) may be allowed to soak into the ground if disposal to sanitary sewer is not possible. o Moderate risk washwaters (e.g., pressure washing with detergent) should be mopped or vacuumed up and disposed of to the sanitary sewer. o Higher-risk wastewaters (e.g., concrete washout, caustic cleaning solutions) should be vacuumed or mopped up as well as possible given the substrate and structures involved, and may require treatment (e.g., neutralization) prior to disposal to the sanitary sewer, or hauled to a waste treatment, storage and disposal facility. o Hydraulic oil, brake fluid and antifreeze should be absorbed and disposed of in accordance with federal, state and local requirements. o Soil and sediment should be removed and disposed of or, if not contaminated, reapplied to a ground surface.  Cleanup or vactoring of open and piped stormwater structures may be necessary. The COL vactor truck is only to be used for cleaning of small quantities of non-hazardous materials (e.g., fats, cooking oils and grease) and other typical waste streams (e.g., garbage, vegetative debris).  Cleanup contractors must be employed by the responsible party for larger cleanups or cleanups of potential or known hazardous materials, such as gasoline, diesel, heating oil, and industrial chemicals.

IDDE Standard Operating Procedures

4.9 Enforcement process Eliminating the illicit discharge or illicit connection is the highest priority, taking precedent over attempting to administer penalties. The inspector uses letters and NOVs to document the observations and corrective actions required. The inspector exercises discretion on whether a letter or NOV is issued, using these criteria as guidance instead of steadfast rules. No NOV issued when:  Substance has not made it to public or private stormwater system,  Minimal cleanup required,  No impact to piped stormwater system or surface waters,  Cooperative responsible parties,  Low chance of impending precipitation that could cause substance to be carried to stormwater system. First NOV warranted when:  Substance made it to public or private stormwater system - open or closed,  Impact is to surface waters, and referred to DEQ for additional action,  Inspector is requiring action beyond small cleanup,  Observations or actions need to be documented for management,  Discharge to stormwater system was intentional,  Lack of cooperation by responsible party. Second NOV warranted when:  Substance made it to public or private stormwater system  Preventive measures discussed during first incident not implemented A second NOV is followed up by a letter to the owner/manager of the company if they were not present at the incident. Depending on the severity of the offense, the second NOV may be referred to City management for enforcement. Third and subsequent observed violations No NOV is issued. Instead, the situation is documented and referred to City management for enforcement. Additional inspections, monitoring, and enforcement, including the potential for violations and penalties, are described in the City ordinance referenced in Chapter 2.

5. Dry weather field screening procedures. The purpose of the dry weather field screening component of the IDDE program is to detect, characterize, and eliminate illicit discharges and connections to the MS4. Elements of this component include:  Performing dry weather field screening of the MS4,  Initiating source tracing investigations when screening indicates the potential presence of illicit discharges or improper connections,  When necessary, using additional tools such as dye-testing and closed circuit TV (CCTV) to identify and/or verify illicit discharges or improper connections,  Stopping illicit discharges and eliminating improper connections using City enforcement processes.

5.1 Desktop prioritization In 2014 the City created a prioritized schedule for illicit discharge screening activities based on a desktop assessment. Parameters for the desktop assessment included the number of outfalls per stream miles, potential illicit discharge sites, flowing outfalls, VPDES permit holders, industrial property classes, and age of development. Permit Year 1 (PY1) dry weather field screening will take place in watersheds with a high IDP watershed ranking, per this map. Additional criteria will be added and the desktop assessment revised in late-2019 or early-2020. Figure 5.1: Prioritized watershed map

IDDE Standard Operating Procedures

5.2 Dry weather field screening The dry weather field screening program uses Field Observations, Field Measurements, Field Analyses and Laboratory Analyses of select physical, chemical and microbiological parameters to characterize flowing discharges. When flow is not present, the field screening program relies on Field Observations such as damage or staining to suggest the presence of intermittent or transitory discharges. Before leaving for the field, the inspector should determine whether the criteria for dry weather are met. Dry weather is defined as a period where less than 0.10 inch of precipitation has been recorded within the preceding 48 hours. Two databases may be used:  https://w1.weather.gov/data/obhistory/KLYH.html provides precipitation and other weather information for the preceding 72 hours at the Lynchburg airport,  The City SCADA Dashboard has weather information for three stations within the City (i.e., College Hill water plant, Virginia Baptist Hospital, Guggenheimer Health and Rehabilitation Center). They may be accessed at Navigation>History>Rainfall Data. The inspector should make a hardcopy printout of the Lynchburg airport data or an Excel document of the SCADA information for inclusion with the ORI forms and other dry weather screening data, and archive it as described in chapter 7. It is recommended that the inspector drive through much of the drainage basin before proceeding to the outfall or point of discharge (POD). The inspector may identify allowed or unauthorized (i.e., illicit) discharges to the storm water system during this drive through that may complicate the dry weather field screening process. In the case of allowed discharges, the dry weather screening may need to be postponed until the discharge is no longer present. The inspector shall proceed with incident response and enforcement procedures (Chapter 4) to stop unauthorized discharges. The general approach to field screening is to begin at the discharge point of a drainage basin, usually an outfall or POD. In some cases accessing a manhole, ditch or other structure is safer or more practical. This initial access point should be downstream of all conveyances and near the discharge point to waters of the State. The Outfall Reconnaissance Inventory (ORI) form (appendix 1) is completed at this initial location. This form is adapted from Brown, Caraco and Pitt, 2004. All seven sections should be completed for systems with flow present, while only five needs to be completed for non-flowing systems, as noted in table 5.1. In large or complex drainage basins, cursory field screening should be conducted at multiple key locations upstream of the initial location. This field screening helps determine:  Where flow is present, and ultimately originates, in the stormwater system,  Relative quantities if there are multiple flow sources,  Whether flow is present in the system that is not making it to the outfall, which may indicate infrastructure damage somewhere.

IDDE Standard Operating Procedures



If flow is present that is not making it to the outfall, since it may be necessary to perform an ORI and/or source tracing.

Usually these key locations are chosen to represent major branches of the stormwater system, however, they may also be chosen based on changes in land use or other criteria. The intent of this cursory screening is to decrease the size of the area screened by an individual inspection. This approach helps detect discharges that may be diluted or masked by groundwater intrusion or blended flows. The ORI form may, but is not required to, be completed at the upstream locations chosen for the cursory field screening. The Diagram of Investigated Structures in section 3 of the ORI or notes on the field maps where the cursory field screening is performed is sufficient if samples are not taken at the upstream locations. If samples are taken at upstream locations then an ORI form should be completed.

5.3 Screening parameters and trigger levels Screening parameters are useful for identifying and characterizing discharges. Trigger values are quantitative and qualitative levels higher than those exceeding what is expected in natural waters. These are based on literature reviews and the collective experience of City scientists and inspectors. Some, such as pH, are based on the City ordinance; however, most are not based on regulatory limits. If a trigger value is exceeded, a source tracing investigation should be conducted. As data becomes available, the trigger and flow chart levels may be adjusted. These parameters are not necessarily pollutants or the most damaging constituent of a discharge. Instead, these parameters are indicators that an illicit discharge or illicit connection may be present. If flow is present a grab sample is taken and analyzed for Primary Parameters (see table 5.2). Results are recorded in sections 3 and 4 of the ORI. City staff perform field sampling and field analysis for all of the Primary Parameters. Of the Secondary Parameters, only chlorine can be analyzed for in the field.

These trigger values are set high because these parameters are commonly found in urban environments due to pets and wildlife waste. The Primary Parameters listed in table 5.2 are observed or analyzed for at all flowing outfalls. The Secondary Parameters are analyzed for based on the best professional judgment of the inspector, usually during source tracing investigations when a source is not identified readily. As the program evolves, each parameter will be evaluated for usefulness in detecting illicit discharges.

5.4 Source tracing Source tracing should be initiated whenever any of the trigger values are exceeded or other field observations suggest potential improper discharges. When possible, the source tracing should be initiated immediately in order to trace intermittent or transitory discharges. If the windshield survey or bracketing survey identify an illicit discharge that needs to be responded to, then begin the incident response and enforcement process.

IDDE Standard Operating Procedures

5.4.1 Windshield survey The windshield survey is a quick inspection of the drainage basin for activities that may be causing an illicit discharge. These activities may include, but not be limited to, vehicle washing, pressure washing, outdoor cleaning, building construction or maintenance, and other discharges to gutters, inlets and ditches. This element is particularly useful when the Field Observation severity indices are the parameters being exceeded.

5.4.2 Bracketing survey The bracketing survey is similar to but more comprehensive than the cursory field screening in that its goal is to determine the source of the discharge by:  determining the branch of the drainage system where the discharge is coming from, and,  then working up that branch to isolate the section that the discharge is originating from. To conduct a bracketing survey, 1. Start at an outfall or POD. 2. Visit junctions (i.e., manholes or ditches with multiple branches). 3. If only one flow is present, proceed up that branch to the next junction. 4. If multiple flows are present, attempt to use Field Observations and Field Measurements to differentiate between the branches. 5. If multiple flows are present and Field Observations and Field Measurements are not sufficient to differentiate the source branch, take samples from each branch. Analyze for the Field Analysis parameter(s) for which the trigger value was exceeded. 6. Compare results to the initial ORI and the trigger values. Proceed up the branch where trigger values are exceeded, repeating at junctions until a section is isolated. 7. Once a junction is reached where no flow is present in any branch or the flow characteristics do not exceed the trigger values, the section has likely been isolated. 8. Once a section is isolated, attempt to identify the source area. Look for evidence of discharges to the stormwater system such as hoses, wet curb gutters and inlets, and wet ground or pavement. Inspect infrastructure and take samples within the isolated section for further narrowing of the isolated section. 9. If the source cannot be identified within an isolated section, consider:  Asking residents and/or businesses if they have performed activities creating wastewater, and where it was discharged to,  Asking residents and/or businesses if dye testing can be performed on potential discharge points (e.g., floor and trench drains, sinks, toilets),  Enlisting the CCTV crew for pipe inspections. 10. If the origin section cannot be isolated, consider:  Comparing Field Measurements, Field Analyses, and/or Laboratory Analyses to the Flow Chart to narrow in on potential sources,  Taking samples for Secondary Parameters,  Revisiting the site once the results of the Secondary Parameters are obtained.

5.4.3 Flow chart The following flow chart (figure 5.3) is adapted from flow charts in Brown, Caraco and Pitt, 2004, with modifications based on inspector experience and program abilities.

5.4.4 Dye testing Dye testing is commonly deployed for piped systems but is also useful in open systems, especially for potential sources such as septic systems and injection wells. While it is possible to do dye testing without additional personnel and without detailed maps, it is highly recommended that additional personnel be enlisted and detailed maps of the isolated section be created. With the permission and cooperation of the property owner, dye tablets or liquids are released into potential source points at a property (e.g., floor and trench drains, sinks, toilets). Substantial potable water is used to carry the dye through the system. Personnel stand by storm and sanitary sewer manholes or other drainage structures to determine where the dye emerges. Remedial actions may be required by the responsible party if dye emerges in the stormwater system. Referral to Community Development Building Inspections may be necessary if private sanitary laterals are plumbed to or leaking

IDDE Standard Operating Procedures

to the stormwater system. Referral to the Virginia Department of Health is required if a failed septic system is identified. Other enforcement and referral needs are determined on a case-by-case basis.

5.4.5 Closed circuit TV If a potential illicit discharge has been isolated to a section of pipe and permission to perform dye tests is not granted or the dye test is not conclusive, then closed circuit television (CCTV) inspection should be performed by trained personnel.

5.4.6 Additional analyses Microbiological, chemical and physical analyses other than the Primary and Secondary Parameters may be deployed on a case-by-case basis if other methods have not successfully identified the source. The inspector will collaborate with WWTP laboratory and contract laboratory personnel to determine appropriate analyses. These may include, but not be limited to:  Fats, oils and grease,  Oil in water analysis methods – free oil, dispersed oil, dissolved oil,  Optical brightener monitoring,  Water discoloration,  Metals,  Genomic Indicator fecal coliform DNA tests.

5.4.7 Timeframe for follow-up investigations Normally source tracing begins immediately after trigger levels are exceeded during dry weather screening studies and in response to environmental incidents. However, there are circumstances such as the need for traffic control or weather events that may require postponement of source tracing. The department will attempt to meet the following timelines in source tracing:  Windshield survey – within 24 hours of determining the need for source tracing,  Bracketing survey – within 48 hours of determining the need for source tracing,  Flow chart – within 5 business days of the bracketing survey not identifying a source,  Secondary Parameters analyses – within 10 business days of the bracketing survey not identifying a source, and,  CCTV survey – within 30 days of isolating a section to be investigated. If these source tracing methods do not identify a source, or the discharge is no longer occurring, then the outfall or POD will be inspected three times during the subsequent six months. Source tracing efforts will be re-initiated if trigger levels are exceeded during these subsequent investigations. If flow is not present or trigger levels are not exceeded, then it will be documented that the source remains unidentified, as per the Permit.

IDDE Standard Operating Procedures

6. Sampling and Measurement procedures The intent of the dry weather screening and source tracing regimen is to find contaminated waters. It is not the intent of the program to obtain research-level data, status and trends quality data, ambient conditions information, or background data for comparisons with other projects. The detection of illicit discharges and connections relies on results that are “abnormal” or “outliers” when compared to “natural waters.” The intent is not to collect stormwater or receiving waters but only waters from sources such as:  Flows from illicit connections  Flows from illicit discharges  Groundwater  Streams, whether perennial, intermittent or ephemeral, which have been piped and may be mixing with improper discharges. The expectation is that the data is to be used to detect and find improper discharges, and not be the sole driver of corrective and enforcement actions. The decision to require an illicit discharge or illicit connection to be ceased and corrected depends on corroborating evidence, such as observations, dye tests, or CCTV investigations. It is important to follow proper procedures in order to protect the value of the data collected and ensure that it is admissible and credible as evidence should legal prosecution be deemed necessary. The following procedures apply mostly to the dry weather screening component, although some apply to the incident response component when samples are taken. All Primary Parameters and one Secondary Parameter (i.e., chlorine) are sampled for and analyzed by the stormwater inspector or other trained personnel using the methods described in Field Measurements and Field Analyses. The Secondary Parameters - E.coli, fecal coliform, total suspended solids and any additional analyses determined on a case-by-case basis - will be collected by the stormwater inspector or other trained personnel and transported to the WWTP or contract laboratory for analysis. Field measurements and field analyses are performed by the stormwater inspector or other trained personnel. Laboratory analyses are performed by laboratory technicians at the Department of Water Resources wastewater treatment plant (WWTP) laboratory or contract laboratories. The WWTP laboratory methods are certified to comply with requirements of VPDES individual permit number VA0024970 and the laboratory maintains Virginia Environmental Laboratory Accreditation Program (VELAP) accreditation for the methods under certificate ID#450024.

6.1 Preparation The following shall be performed prior to field inspections:  Select area based on desktop prioritization. See chapter 5.1. IDDE Standard Operating Procedures

       

Determine outfalls to be visited and generate maps. Use ESRI ArcGIS ArcMap for dry weather screening and Lynchburg Map Viewer for incident response. See chapter 3 and 4.3. For dry weather screening, determine whether dry weather criteria are met. See Chapter 5.2. Assemble, inspect and test equipment. Check batteries. See appendix 2. Check expiration dates on reagents and standards. Print out necessary forms. See appendix 1. Fill clean bottles with deionized water from potable water laboratory. Distilled water obtained from stores is also acceptable. Calibrate pH and conductivity meters. See appendix 2. Clean and rinse sampling bottles and test vials. o Weekly cleaning with dishwashing soap and water of glass vials and plastic sample containers. It is necessary to rinse all plastic and glassware thoroughly. o Vials/cuvettes are cleaned with cuvette cleaning solution on a monthly basis, or when especially high concentrations are encountered. o Acid cleaning at the WWTP laboratory within a fume hood is possible when necessary.

6.2 Guidelines 6.2.1 Alternative brands of pH buffers and conductivity calibration standards can be used if they are of comparable quality and values. Buffers or standard solutions should be labeled with the date they were opened. 6.2.2 Test strips (chlorine, pH) should be stored at room temperature and should not be exposed to light when not in use. Test strips should be replaced by the expiration date. 6.2.3 When sampling at an outfall it is usually most convenient to collect samples directly into a Nalgene bottle. Sampling manholes often requires the use of a telescoping pole and Nalgene bottle. In either case, it is advised that the bottle be rinsed once with deionized water and triple-rinsed with outfall water prior to sample collection. If the flow is very low (e.g., drips or slight trickle), it may be necessary to forgo the triple-rinse. 6.2.4 Whenever possible, the E. coli or fecal coliform sample should be collected directly in the WhirlPak bag. If this is not logistically possible, then:  The container the sample will be collected in should be clean, and if possible, rinsed with rubbing alcohol and multiple rinses of deionized water, and,  Notations should be made on the ORI that the sample was not collected directly in the WhirlPak bag. These precautions are taken in order to minimize the potential for false positives due to sampling irregularities. Source tracing should still be performed if high bacteriological counts result, but if only moderate bacteriological counts are encountered it may be due to contamination during the sampling process.

IDDE Standard Operating Procedures

6.3 Field Observations 6.3.1 Flow Section 2 of the ORI requires flow information.  Flow Present – check appropriate box for Yes, No, Damp, or Standing Water. Check Damp when there is an indication that flow was present but is no longer present. Check Standing Water if water is present but it is not flowing, such as in the corrugations of metal pipe.  Flow Description – check according to the following criteria, regardless of pipe size. Measure the depth of flow and diameter of the pipe. Divide flow depth by pipe diameter. o Check Trickle if the flow depth is less than 10% of the pipe diameter. o Check Moderate if the flow depth is 10-50% of the pipe diameter. o Check Substantial if the flow depth is more than 50% of the pipe diameter.  Measurement – Measure and record the width (W) and depth (D) of the flow in inches. Estimate the velocity of the flow using one of the following means. o Drop a floatable object or debris a measured distance up the pipe. Record the distance (feet) and number of seconds. o Time how long it takes to fill a sample bottle or bucket. Record the volume filled and time to fill. This method is effective for very low discharge rates. Table 6.1: Potential Sources Based on Flow Rate and Frequency Flow Frequency Flow Rate

6.3.2 Physical Indicators Section 4 of the ORI requires observing physical indicators for flowing outfalls, and section 5 requires observing physical indicators for both flowing and non-flowing outfalls. These qualitative assessments may lead to false positives (i.e., caused by natural phenomena) and false negatives (i.e., some illicit discharges do not have observable characteristics). Erring on the side of caution (i.e., initiating source tracking) when results are marginal is advised, while recognizing that best professional judgment must also be exercised.

6.4 Sample collection If flow is present, samples are collected for analysis of the Primary Parameters. Samples should also be collected for the Secondary Parameters if Field Observations indicate there may be an illicit discharge. The ORI form must be completed when samples are collected. The Field Observation, Field Measurement and Field Analysis results are recorded on the ORI form and later entered into a Microsoft Excel spreadsheet. Field Measurements (pH, conductivity and temperature) may be collected in two ways:  The instruments and test papers can be carried to the outfall or other structure and their probes inserted directly into the flow. This is the preferred method as it minimizes the potential for parameter changes due to temperature changes.  A sample can be collected which is then divided into separate containers for measurement and analysis. If this method is used, it is recommended that two 250-ml bottles be collected to ensure adequate quantities of sample. When possible, triple-rinse the Nalgene sample bottle with sample water and then fill the bottle at least 2/3 full. Try to minimize dislodging algae and debris from the outfall or pipe. If algae or debris is visible in the bottle it should be discarded and resampled. A minimum of 35 mL is necessary to perform all of the Primary Parameters if pH and conductivity are measured directly. By collecting 100 mL or more it is possible to pre- rinse the vials and caps with sample water. This helps minimize contamination from prior analyses and dilution from the deionized water used as a rinse prior to sample collection. Inspect the sample bottle for odor, color, and turbidity. If these are noted in the sample bottle then make appropriate notations on section 4 of the ORI. If suds are noticed in the flow, one may wish to do a cursory field test. This is in addition to performing the surfactants test, not a substitution. Shake the sample vigorously. If it generates persistent suds then it is likely that detergents are present (artificial surfactants). If the suds are not persistent then it is suggestive, but not absolutely indicative, that the suds are of natural origin (e.g., decaying vegetation which generates natural surfactants). A perfume

It is not necessary to preserve any of the Field Analysis samples because analysis will be immediate. Most samples for E. coli or fecal coliform may be collected in bags with or without sodium thiosulfate. Sodium thiosulfate in the Whirl-paks is required only if high chlorine concentrations are suspected or measured. Notify the WWTP laboratory as soon as possible if it is anticipated that Laboratory Analyses (fecal coliform or E. coli or total suspended solids) will be necessary. Fecal coliform and E. coli samples must be transported on ice to the laboratory within 6 hours of collection.

6.5 Chain of Custody Chain of Custody requirements are only applicable to the Laboratory Analyses. The transfer of samples between the stormwater inspector and any chosen laboratory will be documented using Chain of Custody forms provided by the laboratory and per the laboratory requirements.

6.6 Analytical Methods and Procedures Analysis methods for each parameter are based on a literature review and the experiences of City staff. Table 6.3 lists the parameters, methods, instruments, and detectable ranges used for dry weather screening. Test strips are used for free and total chlorine and may be used for pH. The following are instructions for using the test strips:  Free and total chlorine:

pH:

Contaminated waters may have concentrations orders of magnitude higher than what the selected methods can determine without diluting samples. Dilutions will not typically be performed to determine an absolute value higher than trigger levels. Results will be reported as greater than the maximum range of the method.

6.7 Field Measurement procedures Field Measurement results are recorded in section 3 of the ORI. Detailed instructions for the Field Measurement procedures are in appendix 2.

6.7.1 pH pH measures hydrogen ion activity on a scale from 1 to 14, with 7 being neutral. Water with a pH below 7 is acidic and water with a pH above 7 is alkaline or basic. Waters with pH less than 5 and higher than 9 are specifically prohibited by City ordinance. The City uses two methods to measure pH:

IDDE Standard Operating Procedures



pH by test strip - This method is to be used when the substance being tested is suspected to contain strong acids or bases, such as during an incident response. Using the pH strip is advised to protect the pH meter, which is effective at measuring weaker solutions. The test strips are very simple to use and require no calibration. pH by meter – This method is used for most dry weather screening. A 3-point calibration is performed prior to dry weather screening, using pH 4.01, 7.00 and 10.01 buffers. The buffers should be NIST certification traceable. Presently the City uses Oakton brand buffers but any comparable, quality buffer of the correct standards may be used.

6.7.2 Conductivity Conductivity, or specific conductivity, is a measure of how well water can conduct an electrical current based on ionic activity and content. It is an indicator of dissolved solids from potential pollutant sources such as sewage, washwater, and fertilizer. Very high conductivities are indicative of commercial and industrial waste, plating bath water, and radiator flushing water. A 2 point calibration is performed every day prior to dry weather screening, using 1000 µS/cm and 10,000 µS/cm potassium chloride-based conductivity standards. The City uses Ricca brand standards but other comparable, quality standards may be used.

6.7.3 Temperature Temperature measurements are possible with either the YSI EcoSense pH10A meter or YSI EC30A conductivity meter. The pH meter is slightly more accurate at measuring temperature than the conductivity meter but the difference is negligible for IDDE work. Extreme temperatures can be indicative of industrial cooling water and sanitary wastewater. A discharge at temperatures greater than 65°C (149°F) is a violation of the City stormwater ordinance.

6.8 Field Analysis procedures Field Analysis results are recorded in section 3 of the ORI. Detailed instructions for the Field Analysis procedures are in appendix 2.

IDDE Standard Operating Procedures

6.8.1 Ammonia Ammonia is produced by the decomposition of plant and animal proteins and is a main ingredient in fertilizer. It is used as an indicator of contamination from fertilizers, washwater, sanitary wastewater, or commercial and industrial liquid wastes. The ammonia to potassium ratio is used to differentiate between sewage and washwater sources. See figure 5.3.

6.8.2 Fluoride Fluoride is added to City potable water supplies to improve dental hygiene. It can also come from the erosion of natural deposits and discharges from a variety of industries, including ceramics, chemical manufacturing, fertilizer manufacturing, glass etching, and metal refining. It has also been found in high concentrations from some heating, ventilation and air conditioning (HVAC) systems. City potable water fluoride concentrations range from 0.34 to 1.00 ppm, with an average of 0.71 ppm. The trigger level has been set at 1 ppm because this would be indicative of discharges from commercial or industrial sources.

6.8.3 Potassium Potassium is an essential element for the proper function of human, animal and plant cells. In natural waters potassium ranges from 0.4 to 15 mg/L, although typically it is lower than 5 mg/L. High concentrations are found in sewage, commercial/industrial discharges, and industrial cooling water discharges. It can also be found in car wash water, industrial process water, metal plating bath water, and radiator flush water. The ammonia to potassium ratio may be used to differentiate between sewage and washwater sources. See figure 5.3.

6.8.4 Surfactants Surfactants are a main component of laundry detergents and dishwashing soaps. The method used by the City measures anionic surfactants, commonly found in laundry detergent, dishwashing liquids and shampoos. It does not measure cationic or non-ionic surfactants, commonly used as wetting agents and in the food industry. This field test helps distinguish between artificial foams and natural foams caused by the decomposition of organic matter.

6.8.5 Chlorine Chlorine is added to the City potable water supply, with concentrations ranging from 0.07 to 2.09 ppm. Chlorine evaporates and combines quickly with organic compounds so it must be analyzed for in the field and is a less reliable indicator than other parameters. High chlorine concentrations may come from laundries, paper mills, pesticide manufacturing and textile bleaching.

septic system. However, it may also be the result of excrement from wild animals, waterfowl, livestock and pets.

6.8.7 Total suspended solids Total suspended solids (TSS) are particles larger than 2 microns found in the water column. These solids can be sediment, sand, silt, plankton, algae and organic particles from decomposing materials. Total suspended solids are a significant factor in observing water clarity. TSS should be analyzed if the turbidity in Section 4 of the ORI is cloudy or opaque. TSS is indicative of erosion, runoff, discharges, and algal blooms.

6.9 Quality Assurance and Quality Control (QA/QC) The dry weather screening program and sampling regimen for source tracing seeks to obtain data of sufficient quality to detect and find illicit discharges and illicit connections. The level of quality control needs to be sufficient only to be confident that a numeric value obtained is precise enough to tell whether a threshold trigger value is exceeded. The methods and equipment used for the program sacrifice some precision, accuracy and sensitivity in order to be efficient, inexpensive, relatively quick, and able to be performed in the field. It is not the intent of this program to provide general water quality data for comparison to other data sets. The detection limits, accuracy and trigger values are listed in table 6.5. QA/QC measures are described in table 6.6.

APPENDIX 3

Standard Operating Procedures Erosion and Sediment Control Inspections Date: January 2014 Revised: August 2021 I.

Purpose

Stormwater runoff from construction site contributes to the degradation of water quality. Properly implemented and maintained erosion control practices can limit the impact this runoff has on waterways. Biweekly (twice monthly) inspections of locally permitted land-disturbance projects helps to ensure that these measures are in place, functioning correctly and reducing sediment laden runoff. Within 48-hours of a runoff producing weather event, additional site visits are conducted furthering the mission of improved water quality. Both the bi-weekly (twice monthly) and 48-hour inspections are required under Virginia Erosion and Sediment Control regulations. These procedures apply to any land change greater than 1,000 square feet in area, which may result in soil erosion from water or wind and the movement of sediments into state waters or onto lands in the state, including, but not limited to, clearing, grading, excavating, transporting and filling of land. For exemptions, see Section 16.1-6(a) of the Lynchburg City Code. II. Procedure 1. Inspections of all permitted sites must be completed by certified erosion and sediment control inspectors within the required timeframes. 2. For commercial projects, signed, approved site plans must be available to the inspector on the jobsite. For residential projects approved as an agreement-in-lieu of a site plan, no plan is required. 3. The inspector will enter the inspection results into the City’s management system, (TRAKit, Lucity, etc.) for reporting purposes. 4. Should the inspector encounter a violation of erosion and sediment control law, the site supervisor or general contractor should be notified as soon as possible to remediate the problem. If no one with authority to authorize the corrections is available onsite, a telephone call to the appropriate person should be placed within 24 hours of the inspection. Additional levels of enforcement may be required. 5. There are three (3) levels of enforcement allowed under erosion and sediment control law: a) standard violation, b) notice to comply and c) stop work order. 6. For typical, non- eminent violations, the inspector shall verbally supply the site supervisor or general contractor with a reasonable deadline to comply with erosion and sediment control law. In all cases of elevated enforcement, verbal notification shall be followed up with written explanation. Hard copies of elevated enforcement must be sent to the property owner via certified mail. 7. For eminent threats to state waters, a stop work order will be immediately issued.

8. Additional enforcement should be explored when compliance through traditional methods is not obtained in a reasonable time. Examples of this include court action and permit revocation. 9. All enforcement correspondence is required to be sent to the property owner. 10. Follow-up inspections are required for all elevated enforcement. 11. Proper personal protective equipment (PPE) must be worn when entering a construction site for an inspection. PPE includes, but is not limited to, steel toed boots, safety vest and construction helmet. III.

Hazard Analysis

There are many potential hazards on a construction. Care should be taken by the inspectors to ensure personal safety while completing an inspection. Personal protection equipment should be worn at all times. IV.

Reporting, Recordkeeping and Quality Assurance

All review and inspection information is entered into the City’s data management systems (TRAKit, Lucity, etc) for follow-up and reporting. While not always possible to enter this data immediately, the expectation is to complete the inspection information within 48 hrs. Monthly compliance reports are run to verify permit issuances and inspection information can be verified at that time. Project records, including approved stormwater management plans, and registration statements will be kept for three years after state permit termination or project completion. Construction record drawings will be maintained in perpetuity or until a stormwater management facility is removed and stormwater management facility inspection records will be documented and retained for at least five years from the date of inspection.

2.0 Applicability 2.1 Single-Family Residential Dwelling Land-Disturbing Activity 2.1.1 Agreement-in-lieu-of: The construction of a single family detached residential structure, with or outside of a common plan of development or sale, equal to or less than 5 acres, may be eligible for an agreement in-lieu-of a stormwater management plan. This agreement shall not require a registration statement or the Department’s portion of the state permit fee for coverage under the General Permit for Discharges of Stormwater from Construction Activities (General Permit). 2.1.2 Requirements: Even though a registration statement for coverage under the General Permit is not required for such a structure, the land-disturbing activity must adhere to the requirements of the General Permit, including, but not limited to preparation of an Erosion and Sediment Control Plan, a Stormwater Management Plan (quality and quantity controls), a Pollution Prevention Plan, long-term maintenance agreement, and construction record drawing. At the discretion of the locality, an agreement in-lieu-of may waive the requirements for the plans and/ or construction record drawing to be signed by a licensed professional. If the VSMP Authority waives the requirements for a licensed professional to complete the plans and/or construction record drawings, then subsequent references to the requirement of a licensed professional seal and signature in the Administrative Guidance Manual and its appendices shall also be waived. 2.2 All Other Land-Disturbing Activities Pursuant to § 62.1-44.15:34 of the Code of Virginia, a stormwater management (SWM) plan and related submittals are required if a land-disturbing activity, which is not a single-family residential dwelling land-disturbing activity, is 1. Equal to or greater than one (1) acre, and/or 2. Part of a Common Plan of Development or Sale (*Refer to section 3.1 below for exceptions and additional information). For land development projects that disturb 5,000 square feet or more of land area, no person shall develop any land for residential, commercial, industrial or institutional use without having provided for appropriate stormwater management measures that control or manage stormwater runoff quality, quantity, and velocity as provided within this article, except those development activities exempted in accordance with subsections 16.2-9(c)2, 16.2-9(c)3, 16.2-9(c)4, 16.2-9(c)5, 16.2-9(c)6, 16.2-9(c)7 and 16.2-9(c)8 of the Code of Ordinances for the City of Lynchburg, Virginia. A VSMP authority permit is only required for projects that disturb one acre or more of land or are part of a common plan of development, except as provided in subsection 16.2-9(b). (Ord. No. O-01-079, 4-24-01, eff. 5-1-01; Ord. No. O-07-047, 4-10-07; Ord. No. O-14-070, § 1, 6-10-14 ) VSMP Administrative Guidance Manual

3.0 Supplemental Guidance 3.1 Common Plan Of Development or Sale As per the Virginia Department of Environmental Quality Virginia Stormwater Management Program (VSMP) Frequently Asked Questions (FAQ), the following provides clarification regarding applicability of the common plan of development or sale clause in the VSMP regulations. 3.1.1 Definition of a ‘Plan’ in a Common Plan of Development: 9VAC25-870-10 (Definitions) of the VSMP regulations describes a common plan of development as “a contiguous area where separate and distinct construction activities may be taking place at different times on different schedules.” Examples of these “common plans of development” meeting this definition include site plans and subdivision plans as defined in § 15.2-2201 (Definitions) of the Planning, Subdivision of Land and Zoning chapter of the Code of Virginia, or as defined by a locality in an ordinance adopted pursuant to this chapter. 3.1.2 Applicability: Individual lots within existing residential, commercial or industrial site plans and subdivision plans that were platted prior to July 1, 2004 may be considered separate land-disturbing activities and require a local VSMP permit and/or a registration statement under the General Permit, except as noted in 3.1.4. July 1, 2004 is the date that provisions for common plans of development were first incorporated into the Virginia Stormwater Management Act. Previous to that date,

VSMP Administrative Guidance Manual

the term was not used or defined. Lots within such platted plans or subdivisions that disturb less than one acre do not have to obtain coverage under 2014 Construction General Permit. Lots within such platted plans or subdivisions that disturb one acre or greater would have to obtain coverage under the 2014 Construction General Permit. 3.1.3 Options for Compliance: If a local VSMP permit is deemed required for the land disturbance within a ‘common plan of development’, the applicant has two options: 1) transfer the original VSMP from the developer to the applicant or 2) apply for new permit coverage. 3.1.4 Exceptions: The VSMP Authority may elect to waive permit coverage under the following situations. 1) Single-Family Homes: For land distributing activity less than 1 acre and within a common plan of development, where the stormwater management plan for the larger common plan of development or sale provides permanent control measures (ie. stormwater management facilities for quantity and quality controls) encompassing the single family residence in accordance with 9VAC25-880-50 , the state will authorize coverage automatically (no registration statement is needed) and the Applicant will not have to pay the Department (DEQ) portion of fee. 2) When the ‘common plan of development’ construction documents and SWPPP accounted for stormwater management (quantity and quality) for the entire development, including grading plans and footprints of impervious surfaces for individual lots. 3) If less than one acre remains of the original common plan, the individual project may be treated as part of a less than one acre development and no permit would be required.

3.2 TMDL Specific Requirements The Applicant shall comply with the requirements of the TMDLs of the City of Lynchburg.

11.0 Enforcement Guidance Portions of the following are an adaptation of the Stormwater Management Enforcement Manual prepared by the Virginia Soil and Water Conservation Board and the Virginia Department of Conservation and Recreation (DCR) dated February 2006. http://www.deq.state.va.us/Portals/0/DEQ/Water/Guidance/ChesBayPreservAct/Stormwat erEnforcementManual.pdf 11.1 Introduction The City of Lynchburg recognizes that its goal of effective enforcement may be accomplished in most cases through informal means by offering compliance assistance to the regulated community and ensuring that any noncompliance is corrected quickly. Nonetheless, the City of Lynchburg will use the full range of its enforcement authority as needed to deter violations and ensure that its mission to conserve and protect the environment and the health and well-being of the Commonwealth’s citizens is fulfilled. 11.2 Authority the City of Lynchburg is authorized by the Code of Virginia § 62.1-44.15:27 to establish and enforce the Virginia Stormwater Management Program (VSMP). 11.3 Violations the City of Lynchburg may consider violations to include, but are not limited to: 1. 2. 3. 4. 5. 6. 7.

No state permit registration; No SWPPP; Incomplete SWPPP; SWPPP not available for review; No approved erosion and sediment control plan; Failure to install stormwater BMPs or erosion and sediment controls; Stormwater BMPs or erosion and sediment controls improperly installed or maintained; 8. Operational deficiencies; 9. Failure to conduct required inspections; and/or 10. Incomplete, improper, or missed inspections.

11.4 Process If a violation(s) is noted by the inspector, the City of Lynchburg may follow the subsequent general steps to enforce compliance of the regulations by issuing: 1. Verbal warning and inspection report; 2. Notice of Corrective Action; 3. Stop work order; 4. Emergency special orders; 5. An injunction; and

VSMP Administrative Guidance Manual

Page 20 of 23

06/13/14

6. Civil penalty(ies). 11.5 Verbal Warning/Inspection Report Under circumstances where an inspection reveals routine noncompliance that can be corrected within a reasonably short time, the City of Lynchburg’s Administrator may choose to issue a verbal warning accompanied by an inspection report that describes the specific problems and includes a schedule for correcting the noncompliance. A copy of the VSMP Permit & SWPPP Construction Inspection Report is found in Appendix N. The purpose of the verbal warning is to give the regulated party responsible for the alleged noncompliance an opportunity to comply voluntarily and thus avoid sanctions that might be imposed by an escalated enforcement response. 11.6 Notice of Corrective Action In accordance with § 62.1-44.15:37 of the Code of Virginia, when the City of Lynchburg Administrator’s initial attempts to secure a voluntary return to compliance are unsuccessful, the Administrator or Department may issue a Notice of Corrective Action (NOCA). Examples of situations where issuance of a NOCA is appropriate include the following: 1. When the regulated party has failed to correct the noncompliance at the site pursuant to a prior Verbal Warning; 2. Where inspections of a construction site indicate a continuing pattern of various routine noncompliance after the City of Lynchburg has issued one or more Verbal Warnings for specific noncompliance; and/or 3. Noncompliance at a construction site is causing an adverse impact to human health or the environment such as a discharge of sediment to a stream or wetland. This situation does not necessarily require prior issuance of a Verbal Warning. The purpose of a NOCA is to inform the regulated party responsible for the alleged noncompliance of the facts surrounding the allegations, the applicable law, and the potential consequences for failing to address the situation, should the allegations prove true. The NOCA also gives the regulated party an opportunity to refute the allegations or to address the discrepancies described in the NOCA within a specified time. It is important that field staff gathers sufficient evidence throughout the informal enforcement process to support escalating the enforcement response, should the need arise. For this reason, field staff should carefully document all of the steps of the informal process in inspection reports, photographs, telephones logs, and field notes. NOCA Process 1. Except for special circumstances (e.g., ongoing adverse impacts to human health or the environment), past noncompliance should be documented in one or more

VSMP Administrative Guidance Manual

Page 21 of 23

06/13/14

3. 4. 5. 6. 7.

Verbal Warning and VSMP Permit & SWPPP Construction Inspection Report issued pursuant to the guidelines in this Manual. Explain to the responsible party in easily understood terms (i) any noncompliance identified during the site inspection or investigation and (ii) describe specific measures needed to achieve compliance. Also explain any (i) documented history of noncompliance at the site, (ii) your decision to issue NOCA, (iii) the reasons for that decision, and (iv) the potential consequences, should the responsible party fail to complete the measures specified in the NOCA within the allotted time (i.e., may result in escalation to formal enforcement, such as a Stop Work Order and potentially a civil charge). Complete the VSMP Permit & SWPPP Construction Inspection Report. Draft the NOCA; refer to Appendix R - Example Notice of Corrective Action letter. Deliver the approved NOCA by hand or send it by certified mail. Conduct a follow- up inspection to ensure compliance. Under circumstances where the responsible party has not corrected the problem or where significant new noncompliance is identified and if the responsible party has good reason for needing a short extension to complete the agreed upon measures or if the new noncompliance is minor and can be corrected immediately, issue a second NOCA. If professional judgment dictates that issuing a second NOCA is not appropriate, initiate a Stop Work Order by discussing the facts of case with the Administrator.

11.7 Stop Work Order In accordance with § 62.1-44.15:37 of the Code of Virginia, if a Permittee fails to comply with the verbal warnings, inspection reports recommended corrective actions, and/or NOCA, the City of Lynchburg or Department may issue an order requiring the owner, Permittee, person responsible for carrying out an approved plan, or person conducting the land-disturbing activities without an approved plan or required permit to cease all landdisturbing activities until the violation of the permit has ceased, or an approved plan and required permits are obtained, and specified corrective measures have been completed. The stop work order shall become effective upon service on the person by mailing, with confirmation of delivery, sent to his address specified in the land records of the locality, or by personal delivery by an agent of the VSMP Authority or Department. 11.8 Emergency Special Orders In accordance with § 62.1-44.15:25 and § 62.1-44.15:37 of the Code of Virginia, if the City of Lynchburg or the Department finds that any such violation is grossly affecting or presents an imminent and substantial danger to (i) the public health, safety, or welfare or the health of animals, fish, or aquatic life; (ii) a public water supply; or (iii) recreational, commercial, industrial, agricultural, or other reasonable uses, it may issue, without advance notice or hearing, an emergency order directing such person to cease immediately all land-disturbing activities on the site and shall provide an opportunity for a

VSMP Administrative Guidance Manual

hearing, after reasonable notice as to the time and place thereof, to such person, to affirm, modify, amend, or cancel such emergency order. 11.9 Injunction In accordance with § 62.1-44.15:37 and § 62.1-44.15:42 of the Code of Virginia, if a person who has been issued an order is not complying with the terms thereof, the City of Lynchburg, Department, and/or the Board many institute a proceeding in the Lynchburg General District Court. 11.10 Civil Penalties In accordance with § 62.1-44.15:42 and § 62.1-44.15:48 of the Code of Virginia, any person who violates any provision of the Code of Virginia or of any regulation, ordinance, or standard and specification adopted or approved hereunder or who fails, neglects, or refuses to comply with any order of the City of Lynchburg, the Department, the Board, or a court, issued as herein provided, shall be subject to a civil penalty not to exceed $32,500 for each violation within the discretion of the court. Each day of violation of each requirement shall constitute a separate offense. 11.11 Payment of Civil Penalties Pursuant to § 62.1-44.15:48 A of the Code of Virginia, civil penalties recovered by a locality's VSMP Authority shall be paid into the City of Lynchburg’s Treasury in which the violation occurred and are to be used for the purpose of minimizing, preventing, managing, or mitigating pollution of the waters of the locality and abating environmental pollution therein in such manner as the court may, by order, direct.

APPENDIX B:

APPENDIX C: Lynchburg, Virginia, Code of Ordinances Chapter 16.2 STORMWATER MANAGEMENT

Chapter 16.2 STORMWATER MANAGEMENT ARTICLE I. GENERAL PROVISIONS Sec. 16.2-1. Purpose. The purpose of this chapter is to reduce the adverse impacts of stormwater runoff from development sites in the City of Lynchburg to the greatest extent possible, by establishing minimum requirements and procedures to control the quantity and quality of stormwater runoff associated with land development. By converting more or less natural landscapes to sites with impervious surfaces, development can cause increases in the quantity and velocity of stormwater runoff and decreases in the water quality of stormwater runoff. Adverse impacts from development shall not be allowed to affect adjacent or downstream property owners. The Lynchburg City Council has determined that the lands and waters comprising the watersheds of the city are valuable and important natural resources, which provide subsistence for life. Therefore, it is in the public interest to establish requirements to regulate the discharge of stormwater runoff from land development projects as provided for in this chapter. The waters and waterways within the city are at times subjected to flooding. Such flooding is a danger to the lives and property of the public and is also a danger to the natural resources of the city. Land development tends to accentuate such flooding by increasing stormwater runoff, due to alteration of the hydrologic response of the watershed in changing from the undeveloped to the developed condition. The flooding produced by the development of real property contributes increased quantities of water-borne pollutants, and tends to increase channel erosion. Such flooding, erosion, and pollution constitute deterioration of the water resources of the City of Lynchburg and downstream communities. The adverse environmental effects of development can be limited by the regulation of stormwater runoff from such land development. Proper management of stormwater runoff will minimize damage to public and private property, reduce the effects of development on land and stream channel erosion, assist in the attainment and maintenance of water quality standards, reduce local flooding, and maintain as nearly as possible, the pre-development runoff characteristics of the area. Procedures provided in this document to reduce stormwater runoff will apply to land-disturbing activity, as done by public and private entities in the City of Lynchburg. (Ord. No. O-01-079, 4-24-01, eff. 5-1-01; Ord. No. O-07-047, 4-10-07; Ord. No. O-14-070, § 1, 6-10-14 )

(b)

Upon the presentation of such petition, the court shall allow a writ of certiorari to review the decision of the city manager, or his designee, and shall prescribe therein the time within which a return thereto must be made to the petition. A copy of the writ of certiorari shall be served upon the city manager.

The duty of the court with respect to the issues of law shall be to review the city manager's, or his designee's, decision de novo to determine if there was an error of law. Whether the fact issues are reviewed on the record submitted by the city manager, or a record made during a review action, the court shall take due account of the presumption of the validity of the city's ordinances, the experience and specialized competence of city staff, and the purposes of the basic laws, regulations, and ordinances under which the city has acted.

(d)

A party shall be deemed to be an aggrieved party for the purpose of filing an appeal if (i) such party has suffered an actual or imminent injury which is an invasion of a legally protected interest and which is concrete and particularized, (ii) such injury is fairly traceable to the decision of the city and not the result of Created: 2021-08-05 16:04:17 [EST]

(Supp. No. 7) Page 21 of 29

Secs. 16.2-63—16.2-69. Reserved.

ARTICLE VI. STORMWATER POLLUTION CONTROL2 Sec. 16.2-70. Purpose. (a)

The 1987 amendments to the federal clean water act (CWA) required the United States environmental protection agency to establish national pollutant discharge elimination system (NPDES) requirements for municipal separate storm sewer systems (MS4). NPDES regulations require the city to reduce the flow of pollutants into waters of the United States through ordinance, permit, contract or other available means.

(b)

Pollutants discharged from the city's municipal separate storm sewer system (MS4) have an adverse impact upon the quality of receiving waters. Stormwater, and any other materials which enter the city's MS4, travel through the system and are discharged into receiving waters with minimal or no treatment. Since pollutants entering this system come from many sources and are to date largely uncontrolled, reduction of pollutant discharges can only be achieved by a broad restriction on a variety of activities occurring throughout the city. This article is intended to prevent pollutants from being discharged by the city's stormwater collection system by requiring all citizens to prevent such pollutants from initially entering the system.

(c)

This article is adopted as an integral part of the city's stormwater management program.

(Ord. No. O-07-032, 3-13-07)

Sec. 16.2-71. Discharges to the city's storm sewer system. (a)

It shall be unlawful and a violation of this article to: (1)

Connect, cause, or allow to be connected, any sanitary sewer to the separate storm sewer system;

(2)

Discharge the following in any amount to the city's storm sewer system, to any private stormwater conveyance system, or to any stormwater management system whether intended for water quality or water quantity control, unless the system conveys the fluids to an appropriate water treatment facility or the discharge is permitted by a Virginia pollution discharge elimination system [VPDES] permit or by a national pollution discharge elimination system [NPDES] permit: (i)

Sewage;

(ii)

Greases;

Sec. 16.2-72. Pesticides, herbicides, and fertilizers. (a)

Pesticides, herbicides, and fertilizers are common household products that have beneficial uses in the homes, lawns and gardens of many city residents. When used properly and in accordance with manufacturer's recommendations they provide significant enhancement of our quality of life. When used inappropriately, however, these products can have unintended negative impacts on the quality of public waters. These consequences frequently are not readily apparent to the individual responsible for the improper usage.

Therefore to reduce the incidences of negative environmental impacts to water quality, the city enacts the following restrictions on the uses of pesticides, herbicides, and fertilizers. (b)

(c)

Pesticides and herbicides. It shall be unlawful: (1)

To use any pesticide or herbicide not approved by the U.S. environmental protection agency (EPA).

(2)

To use any pesticide or herbicide in a fashion not in accordance with manufacturer's recommendations or label directions as approved by the Virginia Department of Agriculture and Consumer Services [VDACS] and the U.S. Environmental Protection Agency (EPA).

Fertilizers. To avoid contamination of water bodies and aquifers: (1)

Fertilizers should be applied in a manner which does not exceed manufacturer's recommendations for frequency and rates approved by the Virginia Department of Agriculture and Consumer Services [VDACS] and the U.S. Environmental Protection Agency (EPA).

(2)

Fertilizers should not be directly applied to impervious areas subject to runoff. Created: 2021-08-05 16:04:18 [EST]

Appendix I: SWPPP Template – Authorized States Instructions To help you develop the narrative section of your construction site SWPPP, the U.S Environmental Protection Agency (EPA) has created this electronic SWPPP template. The template is designed to help guide you through the SWPPP development process and help ensure that your SWPPP addresses all the necessary elements stated in your construction general permit. You should use this template with EPA’s guidance on Developing Your Stormwater Pollution Prevention Plan. Both are available on EPA’s website at www.epa.gov/npdes/swpppguide This template covers the SWPPP elements that most state construction general permits require, however, you are strongly encouraged to customize this template. There are two major reasons to customize this template: •

To reflect the terms and conditions of your construction general permit; and

•

To reflect the conditions at your site

Some states might have their own SWPPP template. If so, use the state-suggested format. In such cases, this document and its template might provide useful background information. Using the SWPPP Template Each section of this template includes “instructions” and space for project information. You should read the instructions for each section before you complete that section. This template was developed in Word so that you can easily add tables and additional text. Some sections may require only a brief description while others may require several pages of explanation. Tips for completing the SWPPP template •

If there is more than one construction operator for your project, consider coordinating development of your SWPPP with the other operators.

•

Multiple operators may share the same SWPPP, but make sure that responsibilities are clearly described.

•

Modify this SWPPP template so that it addresses the requirements in your construction general permit and meets the needs of your project. Consider adding permit citations in the SWPPP when you address a specific permit requirement.

*Notes (see below): [1] The curve numbers and runoff volumes computed in this spreadsheet for each drainage area are limited in their applicability for determining and demonstrating compliance with water quantity requirements. See VRRM User's Guide and Documentation for additional information. [2] Runoff Volume (RV) for pre- and post-development drainage areas must be in volumetric units (e.g., acre-feet or cubic feet) when using the Energy Balance Equation. Runoff measured in watershedinches and shown in the spreadsheet as RV(watershed-inch) can only be used in the Energy Balance Equation when the pre- and post-development drainage areas are equal. Otherwise RV(watershedinch) must be multiplied by the drainage area. [3] Adjusted CNs are based on runoff reduction volumes as calculated in D.A. tabs. An alternative CN adjustment calculation for Vegetated Roofs is included in BMP specification No. 5.

Site tab 5 6 7 8 9 10

Locked annual rainfall of 43 inches for use throughout Virginia since regulatory site based TP load limit is based on this value. Corrected error in formula for summation of nitrogen removal from runoff reduction practices for each Drainage Area tab (cell V79). Added button and shortcut (Ctrl+Shift+R) to clear user inputs from all worksheets. Added shortcut (Ctrl+Shift+D) to clear land cover data from Site tab. Added data entry instruction when user inputs blank (row 8). Moved and revised TP load reduction requirement (now in blue) to columns A to H, rows 27-30.

D.A. tabs 11 12 13 14 15 16 17 18 19 20 21 22 23

Added MTDs: Hydrodynamic, Filtering, Generic. Added "Total BMP Treatment Volume (ft3)" column. Rearranged previous Turf and Impervious input rows to adjacent cells in same row so each practice now located in one row. Consolidated BMP Practice heading and added (RR or no RR label) to each practice to identify those with and without Runoff Reduction. Added " Total Phosphorus Available for Removal in D.A. _ (lbs)". Added button to clear BMP credit areas entered for each practice. Added user prompts to assist with user-input Rainwater Harvesting runoff reduction credit, and MTDs. Renamed Credit and Phosphorus/Nitrogen Efficiency column headers to Runoff Removal Credit and Phosphorus/Nitrogen Removal Efficiency for clarity. Removed "RR" from Column headings referring to runoff volume and TP load from upstream practices (which may be RR or non-RR practices). Renamed "10. Wet Swale (Coastal Plain)" to "10. Wet Swale" in BMP heading in order to improve clarity. The practice is well suited for but not limited to the Coastal Plain. Renamed "14. Manufactured BMPs" section heading to "14. Manufactured Treatment Device"s for consistency with Virginia BMP Clearinghouse. Added "Micro-Bioretention #1" and "Micro-Bioretention #2" to Bioretention headings (6.a and 6.b on tab, respectively) from Spec 9. Replaced zero values from all data entry cells with blank cells, blocked out calculation and data entry cells where input or calculations are not applicable.

Water Quality Compliance tab 24 Optimized and reorganized for improved information output. 25 Added "Runoff Reduction Volume and TP By Drainage Area". 26 Made correction to site volume carried forward from Site tab. (08/22/2017) Runoff Volume and CN tab 27 Reorganized and renamed Channel and Flood Protection tab to Runoff Volume and CN to more accurately reflect information provided. 28 Added user notes regarding limitations of Runoff Volume and CN tab for water quantity calculations. Renamed CNweighted to CN(D.A. X) for the CNs based on soils and land cover types for each drainage area 29 Summary tab 30 Added "Print Preview" button. 31 Fixed runtime error in Summary tab update macro. 32 Added "BMP Treatment Volume", "TP Load from Upstream practice", "TP Removed" and "TP remaining" columns to Summary tab. 33 Optimized macro efficiency and eliminated screen updating/flashing during macros. 34 Corrected Summary tab macro -Turf missing routine missing "<>". 35 Added Error Summary Table to Summary tab (appears only if errors on Site tab or Drainage Area tabs are present) 36 Expanded and improved Runoff Coefficient and CN calculation section. 37 Macro glitch with MS Excel 2016 corrected. (08/22/2017) 38 Added Project Title and Date from Site tab. (8/22/2017)

Added error checks and user prompts to Site tab, DA tabs, and Runoff Volume and CN tab for data input errors. Various format changes thoughout the spreadsheet. Combined 2011 and 2013 BMP spreadsheets into one spreadsheet with a user selection option included in Site tab. User input cell color changed from cyan blue to green; calculation cells changed from mid-grey to light grey; and added final result cell in indigo. Locked annual rainfall of 43 inches for use throughout Virginia since regulatory site based TP load limit is based on this value. Corrected error in formula for total phosporus load reduction requirement. Previous formula was inconsistent with 9VAC25-870-63 A.2 and under certain circumstances provided erroneous TP load reduction requirement for development on prior developed lands. Added button and shortcut (Ctrl+Shift+R) to clear user inputs from all worksheets. Added shortcut (Ctrl+Shift+D) to clear land cover data from Site tab. Added TP Baseline Load for adjusted pre-redevelopement portion (cell C58). Added note (triggered to appear when applicable) below "Land Cover Summary for Redevelopment" - indicating that reduction below baseline TP load (<0.41 lbs/acre) not required as per 9VAC25-870-63. Added error messages when data input areas incomplete or not entered correctly. Conditional formatting (Summary sections grayed out) when input information incomplete or incorrect. Added Pre-redevelopment and Post-development load in lbs/acre/yr (row 57) for additional comparison purposes Corrected error in excel formula for new impervious cover Rv. Corrected errors in excel formula for total site area and Rv's in redevelopment portion: error appeared when soil types change between pre-redevelopment and post-development with no net increases in impervious increase. Added section for Final Post-Development to Land Cover Summaries to show combination of redevelopment portion and new net impervious cover portion. Added informational section in blue (columns B to F, rows 12-14) and input/error guide (columns H to K, rows 12-14) to indicate to users upfront when new net impervious cover is being triggered, when 10 or 20% reductions are being utilized, and when data entry is completed correctly. Added data entry instruction when user inputs blank (row 8). Added option for linear development projects (row 6, and cells D64-G64) Removed "protected" from pre-redevelopment land cover type forest/open space since this is only required in post-development. (08/22/2017) Added error notification to side error notes if total disturbed acreage entered is greater than post-development area entered. (08/22/2017) Added MTDs: Hydrodynamic, Filtering, Generic. 3 Added "Total BMP Treatment Volume (ft )" column. Rearranged previous Turf and Impervious input rows to adjacent cells in same row so each practice now located on 1 row only. Consolidated BMP Practice heading and added (RR or no RR label) to each practice to identify those with and without Runoff Reduction. Added " Total Phosphorus Available for Removal in D.A. _ (lbs)". Added button to clear BMP credit areas entered for each practice. Added user prompts to assist with user-input Rainwater Harvesting runoff reduction credit, and MTDs. Renamed Credit and Phosphorus/Nitrogen Efficiency column headers to Runoff Removal Credit and Phosphorus/Nitrogen Removal Efficiency for clarity. Removed "RR" from Column headings referring to runoff volume and TP load from upstream practices (which may be RR or non-RR practices). Renamed "10. Wet Swale (Coastal Plain)" to "10. Wet Swale" in BMP heading in order to improve clarity. The practice is well suited for but not limited to the Coastal Plain. Renamed "14. Manufactured BMPs" section heading to "14. Manufactured Treatment Device"s for consistency with Virginia BMP Clearinghouse. Added "Micro-Bioretention #1" and "Micro-Bioretention #2" to Bioretention headings (6.a and 6.b on tab, respectively) from Spec 9. Replaced zero values from all data entry cells with blank cells, blocked out calculation and data entry cells where input or calculations are not applicable.

Water Quality Compliance tab 35 Optimized and reorganized for improved information output. 36 Added "Runoff Reduction Volume and TP By Drainage Area". 37 Added section for linear development projects (rows 21-26) Runoff Volume and CN tab 38 Reorganized and renamed Channel and Flood Protection tab to Runoff Volume and CN to more accurately reflect information provided. 39 Added user notes regarding limitations of Runoff Volume and CN tab for water quantity calculations. Renamed CNweighted to CN(D.A. X) for the CNs based on soils and land cover types for each drainage area 40 Summary tab 41 Added "Print Preview" button. 42 Fixed runtime error in Summary tab update macro. 43 Added "BMP Treatment Volume", "TP Load from Upstream practice", "TP Removed" and "TP remaining" columns to Summary tab. 44 Optimized macro efficiency and eliminated screen updating/flashing during macros. 45 Corrected Summary tab macro -Turf missing routine missing "<>". 46 Added additional pre and post site data onto Summary tab. 47 Added Error Summary Table to Summary tab (appears only if errors on Site tab or Drainage Area tabs are present) 48 Expanded and improved Runoff Coefficient and CN calculation section. 49 Added summary information for linear projects, only populates if applicable.

Inspected By: COL Inspector’s Name

Inspection Date: Month Day, Year

The current site development listed at the above location has previously failed routine Erosion & Sediment Control (ESC) inspections performed. Requests for corrective actions have been disregarded, and there is little to no improvement across the site. An inspection of the above referenced property revealed the following violations of the City of Lynchburg's ESC & Stormwater Management (SWM) Ordinances. Please correct the following: • • • • •

•

All denuded areas that are at final grade need permanent stabilization (MS1, MS 3 and VESCH 3.32); There is a piece of silt fence (SF) that needs maintenance near the road (MS4 and VESCH 3.05); SF needs to be extended and horseshoed up the slope, located near the discharge pipe from the sediment basin (MS4 and VESCH 3.04); Stormwater conveyance channel (SCC) #2 needs to have sediment cleaned out of it, as a result from the silt blowout. This channel will also need to be re-stabilized (MS1, MS3, MS8, MS11, VESCH 3.17 and VESCH 3.32); The rip-rap in the outlet protection, located below the discharge pipe of the sediment basin, as well as at the end of SCC #2, will need to have all accumulated sediment removed, so that it does not further escape the site and flow down SCC #2, towards Tomahawk Creek (MS19, VESCH 3.17 and VESCH3.18); and The site previously amended the site plan, switching the channel lining for SCC #2 from riprap to grass/vegetative lining. However; it was recently discovered on-site that there is either a natural spring or other constant flow of groundwater inside of the flow path for SCC #2. Not only does this create a concern for achieving permanent stabilization inside of the channel (water appeared to have washed underneath the sod during the last significant rain event, which resulted in the sod pealing out), but this may also affect the capacity for SCC #2. This item will need to be reviewed by an engineer and design modifications may be needed. For this reason, the City is asking that the site provide an engineered proposal/solution. If additional time is needed, a timeline should be submitted to City staff.

Previous site inspections show that this site has been in violation of the ESC Law and Regulations since Month Day, Year. Notice is hereby given that these violations shall be corrected in accordance with the Virginia ESC Law and state minimum standards immediately. The violations should be resolved by Month Day, Year. Failure to correct all ESC/SWM items will result in a Stop Work Order for the site. Environmental Compliance Inspector:

Stormwater Management Facility Inspection Procedures Manual City of Lynchburg Department of Water Resources Stormwater Division

Introduction: A SWMF (Storm Water Management Facility) inspection is a federally mandated and municipally enforced program created to reduce and eliminate soil erosion and contaminants from non permeable land areas that are derived through normal precipitation. Each functional SWMF basin is designed to trap sediment and expedite natural decomposition of unwanted nutrients, organic and inorganic debris alleviating TMDL (Total Maximum Daily Load) levels. The goal of this process is to diminish the amount of natural and unnatural contamination that is entering city storm water systems and local watersheds which empty to the James River.

Inspection Safety: 1) Always wear safety vest, steel toes and hard hat when conducting field inspections. Some SWMF’s sites may be next to roads creating dangers from motor vehicles. 2) Proper equipment such as manhole hooks is necessary for removing manhole covers and vault inlets due to extreme weight. 3) Always remain observant when conducting inspections. If emergencies arise call the water resources safety manager or 911. 4) Always carry radio or cellular telephone to stay in contact in case of unforeseen emergency. 5) Inform owner/tenant when inspecting site to avoid conflict and to make public aware of inspection teams presence. 6) Confined Spaces Certification is required for department manager and inspection team needs to be trained in Confined Spaces safety. Any questions

about Confined Space issues shall be brought to the safety manager’s attention. 7) Any unknown chemical presence or other unknown contaminant is to be reported to safety manager for assessment and possible testing. Never touch visible contaminant with bare skin or breathe unpleasant vapors due to hazardous health reasons. If unavoidable call the safety manager or 911 for assistance. 8) Basic First Aid and CPR training or certification shall be held for all inspection team members and a list of emergency phone numbers in case of unforeseen emergencies.

Inspection Training and Certifications:

1) Team leaders require training and understanding of basic surveying equipment and technique for the purpose of checking elevation changes, sediment accumulations, and structural degradation. 2) Certification in SWMF field inspection is required through sanctioned organizations i.e. Department of Environmental Quality. 3) Basic Confined Spaces training is required for all team members conducting field inspections due to manufactured SWMF’s that are vaulted within the ground and are covered. 4) Basic First Aid knowledge is required for all inspection team members due to the nature of environment and discreet locations. 5) Basic CPR knowledge is required for all inspection team members due to the nature of environment and discreet locations. 6) Understanding and training for basic computer skills and photography are mandatory for inspection process and correct documentation. 7) Inspectors must obtain and upgrade knowledge of city maintained computer programs Lucity, Trak-It, Arc Map etc. for proper inspection information and documentation to maintain MS4 and EPA compliance.

Inspection Schedule: 1) All public and private SWMF’s within the City of Lynchburg are scheduled for routine annual inspection for MS4 compliance. Privately maintained SWMF’s must be inspected by the property owner or designee per their Stormwater Management Agreement. If the inspection report for privately maintained SWMF’s is not received, the City reserves to right to complete the inspection. 2) All inspections are reviewed by the Department of Water Resources for enforcement recommendations. Re-inspections may be done after allotted time frames initiated through the Stormwater Division. (30; 90; 180) days after original inspection date.

Inspection Processes: A) Pre Inspection Steps: 1) Secure information on location and SWMF type utilizing online municipal database. 2) Correlate SWMF number/numbers with site plan located on city Trak-It program or other data storage site. 3) Always view plan before entering property to have knowledge of what to locate and inspect. 4) Secure laptop computer/tablet and digital camera/phone for proper documentation and information requirements. 5) Have several inspection forms before leaving, due to possible mistakes, each SWMF Inspection Form has the flexibility to accept data for each type of basin type.(See attached form for example) 6) All necessary PPE and safety equipment are to be accounted and secured before leaving office for inspections.

B) Inspection Steps: 1) If possible, make verbal contact with owner/tenant when team first arrives on site. 2) Always add basic information to inspection sheet before actual inspection occurs; address, site I.D. #, names of inspectors, type of SWMF, etc. This will make data entry quicker and easier when completing the documentation of inspection. 3) Correlate photographs with each site. This can be accomplished by photo number and date. 4) Visually locate all pertinent parts of SWMF, pretreatment area, inlets, outlets, forebay, and basin (etc.).Understand how the site functions. 5) Make notes and photo infractions to each part of SWMF. Always take as many notes and pictures as you think sufficient, there is no such thing as too much information. 6) If site does not contain all SWMF parts named on inspection sheet; add N/A to sheet under each part that does not apply to the particular SWMF. 7) All information gained during site inspection is utilized for inspection form completion. Proper inspection form completion and pertinent photographs are then entered into the appropriate tracking system. 8) All follow-up letters sent to owner/tenant will be orchestrated through the Department of Water Resources.

Types of SWMF’s Inspected: Not all Basins are precise or exact and Site Plans should always be surveyed before inspections. 1) Dry Detention Basin: Typical Dry Detention basins posses Pretreatment Area, Inlet(s), Forebay(s), a Dry Main Treatment area, Embankment, Outlet Orifice(s) to Receiving Waters and an Emergency Spillway. 2) Wet Detention (Retention) Basin: Typical Retention basins include Pretreatment Area, Inlet(s), Forebay(s), a Wet Main Treatment area, Outlets to Receiving Waters and Emergency Spillways. 3) Bio Retention Basin / Filterra Systems : Typical Bio-Retention Basins posses Pretreatment Area, Perimeter of cell, Inlet device(s), Landscape (Vegetation, Mulch, Engineered Soil Media), Underdrain and Outlets to Receiving Waters. Bio-Retentions are designed for lighter precipitation, if excessive rainfall occurs it will bypass the Bio-Retention Cell. 4) Permeable Pavement: Typical Permeable Pavement areas include the Perimeter of Pavement Area, Surface of Permeable Pavement, and Outlets to Receiving Waters. 5) General Infiltration Practices: General Infiltration Systems are the most diverse. These systems are constructed for retrofitting sites. They can include, but not limited to, Pretreatment Area, Underground Vaults, Inlet Grates and C.D.I’s, Grass Swales, Rip Rap Barriers, Landscape (Vegetation, Mulch, and Soil Media), Outlets, to Receiving Waters and Emergency Spillways. 6) Stormwater Wetland Areas: Typical Wetland Areas include a Pretreatment Area, Perimeter of Basin, Inlet Device, Forebay(s), Deep Pool and Shallow Land Areas, Embankments, a Micro Pool, Outlet Orifice, Emergency Spillway to Receiving Waters. 7) Grassy Swale / Filter Strip: Grassy Swales and Filter Strips utilize the vegetative covered ditch to hold sediment and nutrients while conveying storm water to designated inlets and outlets. Typical Swales and Strips posses a Pretreatment Area, Vegetative Swale or Embankment, Flow Diversion or Inlets, Outlets and Emergency Spillway to Receiving Waters. 8) Manufactured SWMF’s: There are several types of Manufactured SWMF’s that require regular maintenance. Each site plan should entail proper information describing the manufacturer maintenance schedules. Typical layouts for manufactured SWMF’s can vary, but should include a Pretreatment Area(s) , Flow Diversion (Downspouts, Gutters, Curbing Breaks etc.), Inlets(Grates, CDI’s Graveled Orifices etc.), underground Treatment Vaults or Cisterns, Sediment Detection Pipe or Riser (for visual inspection), Piped Outlets to Receiving Waters. Vortechs and Stormceptor are two commonly used systems. Always use caution when inspecting underground vaulted systems due to “Confined Spaces” regulations. 9) Level Spreaders and Riparian Buffers: These two environmental friendly SWMF’s are commonly part of larger storm water maintenance sites where 4

several types of basins are utilized. Both systems help disperse rainfall by spreading storm water out over larger areas, without creating severe erosion. *Healthy vegetation is the most important aspect of Riparian Buffers. Tree and plant root systems hold soil in place during rainfall; this is the key to correct functionality. *Correctly engineering and constructing Level Spreaders is the keys to their functionality. Water is slowed then diverted evenly over a vegetative area alleviating erosion and allowing nutrients to be utilized by the plant life. Both systems spread storm water and help to utilize unwanted nutrients.

Enforcement In the event that a privately maintained SWMF is found non-complaint: 1) Privately maintained SWMF’s receive a total of three notifications to complete annual inspection report for compliance. All reports are due April 1st of the following year. 2) Inspection reports not received within that time frame will receive a final non-compliance notice sent from the Department of Water Resources and allotted 60 days to complete inspection. 3) Inspection reports not received within those 60 days will be deemed noncompliant and the City reserves the right to perform the inspection, maintenance, and repair of the SWMF. The City reserves the right to recover the costs from the responsible party. In the event that the responsible party fails to comply with the approved plan: 1) Notice shall be served by registered or certified mail to the responsible party or by delivery at the land development site to the appropriate agent or employee. 2) Notice shall specify the measures needed to comply and the time within which such measures shall be completed. Failure to comply within the specified time may result in the permit or approval being revoked or the responsible party deemed in violation of the City Stormwater Management Ordinance. 3) Any person found in violation of the City Stormwater Management Ordinance shall be guilty of a misdemeanor and shall be subject to fine or imprisonment. 4) Civil action against may be brought against any person for violation of the City Stormwater Management Ordinance.

Use absorbents (kitty litter, rags, sand, etc) to clean up spills, sweeping, vacuuming, and scrapping off dried debris. This waste material should be disposed of as solid waste. iii) Solids should be removed from the area prior to pressure washing and a filter bag or similar filtration device should be used to remove suspended solids from the wastewater. iv) If you do not use any chemicals or detergents and are only cleaning surfaces of ambient dust, then you may direct the wastewater to nearby landscaping or vegetated area or contain it onsite and allow it to evaporate. v) When discharging wash water to landscaping, make sure water is absorbed into vegetated or permeable surfaces (ex: grass) and does not cause erosion or run off into a storm drain or paved area. vi) Pressure wash with minimal water as possible. vii) All other wash water must be captured for proper disposal. viii) Any wash water with a visible sheen or chemicals are required to be captured and disposed of through a certified disposal facility or waste water treatment facility. Use an absorbent pad or boom to eliminate any oil from the discharge. A waste manifest must be obtained when a third‐party disposal is used. ix) When possible, spot clean, steam clean, or scrape clean certain dirty areas rather than pressure washing the entire structure.
