HISTORY & CONSIDERATIONS:

None.

RULE C: STORMWATER MANAGEMENT Standards  Proposed discharge rates for the 2‐, 10‐, and 100‐year events shall not exceed existing rates.  Developments and redevelopments must reduce runoff volumes in the amount equivalent to an inch of runoff from the impervious areas of the site.  Stormwater must be pretreated before discharging to infiltration areas to maintain the long‐term viability of the infiltration area.  Developments and redevelopments must incorporate effective non‐point source pollution reduction BMPs to achieve 90% total suspended solid removal.

Findings 1. A hydrograph method based on sound hydrologic theory is used to analyze runoff for the design or analysis of flows and water levels.

2. Runoff rates for the proposed activity exceed existing runoff rates for the 2‐, 10‐, and 100‐year critical storm events at the Gibbs Outlet. However, runoff rates for the overall site decrease. The applicant has received confirmation from the City that the storm sewer at the Gibbs Outlet has capacity to absorb the small increase in rate at this location. Stormwater leaving the project area is discharged into a well‐defined receiving channel or pipe and routed to a public drainage system.

3. Stormwater runoff volume retention is achieved onsite in the amount equivalent to the runoff generated from 1.1‐inch of rainfall over the impervious surfaces of the development. a. The amount of proposed impervious is 276,606 square feet. b. Volume retention required: 276,606 ft2 x 1.1 inches x 1 ft/12 inches = 25,356 ft3

Table 1. Proposed volume retention through abstraction (i.e. infiltration, reuse).

Volume Volume Retention 1.1‐inch 2.5‐inch Retention BMP Provided below 3 Runoff (ft ) Runoff (ft3) Required (ft3) outlet (ft3) Infiltration Trench 1 12,808* 5,666 12,877 Infiltration Trench 2 13,038* 15,102 34,322 25,356 Total 25,846 cf* *Volumes include perforated pipe storage, which was not calculated by applicant.

c. Banking of excess volume retention is not proposed. d. Infiltration volume and facility sizes have been calculated using the appropriate hydrologic soil group classification and design infiltration rate. e. The infiltration areas are capable of infiltrating the required volume within 48 hours. f. Stormwater runoff is pretreated to remove solids before discharging to infiltration areas.

g. The Hantush groundwater mound spreadsheet predicts a mound depth of approximately 0.7’ at the house footprint on 1516 Como Avenue. MnTopo shows surface elevation of 927’ at house. Based on soil boring B‐19, there is at least 11 feet of separation between basement and groundwater mound. h. The Hantush groundwater mound spreadsheet predicts a mound depth of approximately 0.9’ at the house footprint on 1340 Como Avenue. MnTopo shows surface elevation of 928’ at house. Based on soil boring B‐18, there is at least 11 feet of separation between basement and groundwater mound.

4. Alternative compliance sequencing has not been requested.

5. Best management practices achieve 90% total suspended solids removal from the treated runoff generated on an annual basis.

6. A memorandum of agreement for maintenance of stormwater facilities exists between the City of St. Paul and the CRWD. Adequate maintenance access is provided for the underground systems.

RULE D: FLOOD CONTROL Standards  Compensatory storage shall be provided for fill placed within the 100‐year floodplain.  All habitable buildings, roads, and parking structures on or adjacent to a project site shall comply with District freeboard requirements.

Findings 1. There is no floodplain on the property according to FEMA. 2. It is unknown if all habitable buildings, roads, and parking structures on or adjacent to the project site comply with CRWD freeboard requirements. However, adequate conveyance has been provided to prevent flooding.

RULE E: WETLAND MANAGEMENT

Standard  Wetlands shall not be drained, filled (wholly or in part), excavated, or have sustaining hydrology impacted such that there will be a decrease in the inherent (existing) functions and values of the wetland.  A minimum buffer of 25 feet of permanent nonimpacted vegetative ground cover abutting and surrounding a wetland is required.

Findings 1. There are no known wetlands located on the property.

RULE F: EROSION AND SEDIMENT CONTROL Standards  A plan shall demonstrate that appropriate erosion and sediment control measures protect downstream water bodies from the effects of a land‐disturbing activity.  Erosion Control Plans must adhere to the MPCA Protecting Water Quality in Urban Areas Manual.

Findings

W:\07 Programs\Permitting\2019\19-029 Como Ave Trail Project\19-029 Permit Report_R2.doc Page 3 of 4

1. Erosion and sediment control measures are consistent with best management practices, as demonstrated in the MPCA manual Protecting Water Quality in Urban Areas.

2. Adjacent properties are protected from sediment transport/deposition.

3. Wetlands, waterbodies and water conveyance systems are protected from erosion/sediment transport/deposition.

4. Total disturbed area is 10.27 acres; an NPDES permit is required. A SWPPP has been submitted.

RULE G: ILLICIT DISCHARGE AND CONNECTION Standard  Stormwater management and utility plans shall indicate all existing and proposed connections from developed and undeveloped lands for all water that drains to the District MS4.

Findings 1. New direct connections or replacement of existing connections are not proposed.

2. Prohibited discharges are not proposed.

Recommendation: Approve with 2 Conditions Conditions: 1. Provide plans signed by a professional engineer per the Minnesota Board of AELSLAGID. 2. Revise Plans to address the following: a. Add note to cross‐section detail on Sheet 162 in plans stating that fabric shall be excluded from the bottom of the infiltration practice. b. The sump depth in structures MH 229, MH 225, MH 323, and MH 319 shall be four times larger than the outlet pipe per EPA guidance. The perforated spreader pipe is 12‐inches, which requires a 4‐foot sump.

DATE: TO: FROM: RE:

January 3, 2020 CRWD Board of Managers Sarah Wein, Monitoring Coordinator 2019 Lakes Update

IV. Special Reports – 2019 Lakes Update (Wein)

Background There are five lakes within the boundaries of CRWD: Como Lake, Crosby Lake, Little Crosby Lake, and Loeb Lake in St. Paul, and Lake McCarrons in Roseville. Each lake is collaboratively monitored

by Ramsey County Public Works (RCPW), the Ramsey County Soil and Water Conservation Division, the Minnesota Department of Natural Resources (DNR), and CRWD to evaluate overall health, assess compliance with water quality standards, and determine if each lake supports its designated uses for swimming, fishing, and/or aesthetics. Data has been collected annually on each lake for varying periods of record, with the Como Lake dataset being the longest, dating back to 1984.

Issue In 2019, CRWD, in partnership with RCPW and the Ramsey County Soil and Water Conservation Division,, collected chemical, physical, and biological data from all five District lakes. Data collected included: dissolved oxygen, total phosphorus, chlorophyll-a, temperature, Secchi depth, phytoplankton, zooplankton, macrophyte samples, biovolume surveys of vegetation, and continuous water level data.

All of the lakes data collected in 2019 have been analyzed and summarized. Historical lake data and summer average total phosphorus, chlorophyll-a, and Secchi depth calculations are also available online via the CRWD Water Data Portal. An update will be given on 2019 lake monitoring, 2019 lake quality in comparison to the historical data record, 2019 accomplishments, and 2020 initiatives.

Requested Action None.

Action Items A) AR: Approve Minutes of the December 18, 2019 Annual Meeting and Regular Board Meeting (Sylvander)

One change was noted, the correct Board of Managers per diem should be $125 not $75.

Motion 20-003: Approve the Amended Minutes of the December 18, 2019 Annual Meeting and Regular Board Meeting.

Texer/Sanders Unanimously approved B) AR: Adopt Resolution for Cost Cap and Stormwater Impact Fund Contributions (Kelley) Mr. Kelley provided a review of the amendments to the cap on cost for Linear Projects and Stormwater Impact Fund. The Joint Technical Advisory Committee (TAC) met September 19, 2018 to discuss proposed amendments to District Rules. Draft Rules were distributed for informal comment in January of 2019, the Board authorized distribution of the draft amended rules for 45-day review ending on April 22, 2019, and the Rules were adopted on June 5, 2019.

During the Joint Rules TAC meetings, Mr. Kelley shared how staff presented cost data that indicated the current cost cap ($30,000/impervious acre) and stormwater impact fund contribution ($40,000/impervious acre) amounts were insufficient to achieve water quality performance goals, and proposed increases to $75,000/impervious acre and $100,000/impervious acre, respectively. In order to allow time to plan and budget for upcoming projects, it was agreed the increase would not take effect until 2020. Mr. Kelley provided a review of the volume bank credits.

Motion 20-004: Adopt Resolution Setting the Cap on Cost for Linear Projects at $75,000/impervious acre.

Texer/Sanders Unanimously approved Motion 20-005: Adopt Resolution Setting the Stormwater Impact Fund Contribution Rate at $100,000/impervious acre.

January 15, 2020 Board Meeting V. Action Items C) SRF Amendment for Additional Parkview Construction Administration (Zwonitzer)

DATE: TO: FROM: RE:

January 8, 2020 CRWD Board of Managers Nate Zwonitzer, Water Resource Project Manager Approve Amendment with SRF for Additional Construction Administration for the Parkview Center School BMP

Background In 2016 CRWD was awarded a $1.76 million grant through BWSR’s Targeted Watershed Program (TWP) for work in the Como and McCarrons subwatersheds. One of the potential projects identified in the grant application was a regional BMP at Parkview Center School located at the intersection of County Road B and Dale Street in Roseville. Phase one of project construction started in October and was completed in December of 2019. Phase two, which includes final connections to the County Road B storm sewer and site restoration will occur in the spring of 2020.

Issues CRWD staff requested assistance from SRF for several time sensitive items that came up between contractor selection for the Parkview Project and the beginning of construction. They included additional assistance with researching contractors, permit coordination, adding a construction camera, and plan modifications including upsizing the filter vault. SRF has submitted the enclosed proposal for completing the additional tasks at a cost of $25,038. Staff recommend approving a contract amendment with SRF for the additional construction administration with funding from #410-16752 which has a 2019 budget of $742,320.

Requested Actions Approve Amendment #8 to the consultant services agreement with SRF for construction administration of the Parkview Center School Filtration BMP for an amount not to exceed $25,038 and authorize the Administrator to execute the amendment and additional amendments up to $10,000.

Enc: Parkview Center School BMP Project Proposal for Misc. Additional Professional Services – Amendment 8 dated December 23, 2019 \\crwd01-dc01\company\06 Projects\McCarrons\Parkview Center School TWP\Board Items\Board Memo Parkview SRF Amendment 8_1-15-20.docx

Our Mission is to protect, manage and improve the water resources of Capitol Region Watershed District.

SRF 10569.01

December 23, 2019

Mr. Nate Zwonitzer Water Resources Project Manager Capitol Region Watershed District 595 Aldine Street St. Paul, MN 55104 Subject:

Parkview Center School BMP Project Proposal for Misc. Additional Professional Services - Amendment 8

Dear Mr. Zwonitzer: As discussed, SRF Consulting Group, Inc. is pleased to provide this proposal for additional professional services for the referenced project.

Scope of Services Several extenuating issues came up during the construction administration phase of this project that have required the following additional services beyond those in our current contract, including: 1.

2.

3.

4.

5.

City and County permit submittals Late plan changes Contractor selection process Change Order #1 Addition of a construction camera

These five items occurred under aggressive schedules and as such were completed prior to executing this amendment and are listed under Task 1. Task 2 is additional work needed to inspect grading and turf establishment for the ballfield that will occur in the spring of 2020.

Our proposed scope of services consists of the tasks listed below.

Task 1.

Additional Pre-Construction Activities (completed)

Several activities were needed prior to bidding and during bidding that were outside the original scope of work.

1. Assembled and submitted City and County permit applications to obtain permits.

2. Incorporated late plan and specification changes to add second pre-bid meeting and address comments from the County (Addendum #1 and #2).

3. Analyzed potential bid alternates to add field grading (Bid Alternate #1).

4. Added Bid Alternate #1 to construction documents.

An Equal Opportunity Employer

Mr. Nate Zwonitzer Capitol Region Watershed District

5. Performed shop drawing reviews which included significant coordination with the supplier to evaluate various configurations to resize the treatment system. Negotiated with supplier to find the best option for the CRWD. 6. Assisted with evaluating the bidders, including additional meetings beyond what was scoped for CA. 7. Developed and executed Change Order #1.

8. Provided construction camera research, coordination, installation, maintenance and removal.

Task 2.

Construction Administration Additional Work (yet to complete)

1. Additional observation time for the Bid Alternate #1 construction activities (field grading/etc.).

Assumptions The following assumptions have been used to develop the scope of services and fee estimate in addition to those found in the tasks.

-

Hours associated with the construction camera includes labor for coordination time with camera vendor, one site visit for location determination, one site visit to install and another to uninstall.

Expenses include camera service fee for 2 months at $549/month and solar station lease at $1,848 for a 2-month term.

Based on the current contractor schedule we believe the overall construction timeline will be reduce by roughly 4 weeks (or about 40%) which reduces the amount of time our inspector will spend on the site.

As discussed, this savings has been offset by providing a more experienced inspector at the onset. o This contract amendment has been adjusted down by $5,000 based on this savings.

Schedule We will complete the aforementioned scope of work within a timeframe mutually agreed upon with you, once we receive a notice to proceed.

Basis of Payment/Budget We propose to be reimbursed for our services on an hourly basis for the actual time expended. Direct project expenses, such as printing, supplies, reproduction, etc., will be billed at cost and mileage will be billed at the current allowable IRS rate for business miles. Invoices are submitted on a monthly basis for work performed during the previous month. Payment is due within 30 days.

Based on the scope of services detailed above, we estimate the not-to-exceed cost of our services to be $25,038, which includes both time and expenses. A detailed Proposed Budget (Attachment A) is attached.

Changes in the Scope of Services It is understood that if the scope or extent of work changes, the cost will be adjusted accordingly. Before any out-of-scope work is initiated, however, we will submit a budget request for the new work and will not begin work until we receive authorization from you.

January 15, 2020 Unfinished Business VI. B. Ford Area C Update

DATE: TO: FROM: RE:

January 9, 2020 CRWD Board of Managers Bob Fossum, Division Manager Ford Area C Update

Background Ford Area C is located west of Mississippi Blvd. immediately adjacent to the Mississippi River. For many years, Ford used this parcel to dump waste products from their manufacturing processes. More recently the site was capped with a paved parking lot. The MPCA has been working with Ford to investigate the content and magnitude of the material that is located on Area C. On October 18, 2018, Barr Engineering completed a Technical Evaluation (enclosed) and provided recommendations for additional monitoring to fully characterize the magnitude and extent of contaminant migration at the site.

Issues On October 23, 2019, Ford Motor Company responded to the recommendations that were made in Barr’s Technical Evaluation Memo (see enclosed memo from Arcadis). Barr and staff have reviewed those responses and have compiled a table that summarizes the recommendation and response to them (see enclosed memo with table). Staff will review the table with the Managers and discuss next steps.

Additionally, staff will be meeting with MPCA and Ford on Monday, January 13, 2020 to further discuss CRWD’s recommendations for monitoring and data collection. Staff will review the outcomes of that meeting with the Managers.

Requested Action None, review and comment only. enc:

Technical Memorandum To: From: Subject: Date: Project:

Bob Fossum – Capitol Region Watershed District Evan Christianson, Jim Eidem, and Dan Fetter Ford Plant Area C Review October 1, 2018 23621278.00

This technical memorandum summarizes Barr’s review of several documents related to Area C disposal area at the Ford Motor Company’s, Twin Cities Assembly Plant (TCAP) in St. Paul, Minnesota. The documents reviewed included:

  

Area C ‐ Comprehensive Site History and Investigation Report dated May 2017 (Arcadis, 2017a) 2017 Fourth Quarter Groundwater Sampling Summary (Arcadis, 2018) 2017 comment letters to MPCA (and MPCA’s responses) from Capitol Region Watershed, Friends of the Mississippi River, National Park Service, and District City of St. Paul/Landmark Environmental

The reports and comments address a variety of topics, but this memo presents Barr’s review and comments primarily related to the groundwater to surface water migration pathway at Area C near the Mississippi River.

1.0 Background Area C (Site) is a former waste disposal area located in the Mississippi River valley gorge, west of Mississippi River Boulevard (Figure 1). Waste disposal in Area C included dumping an unknown volume of industrial waste (including paint sludge, old paints and solvents, and drummed materials) and other solid waste and excavated materials from TCAP. The industrial waste was covered by an unknown volume of construction debris and soil fill associated with projects at Lock and Dam No. 1, TCAP, and road maintenance / construction projects. The debris and soil fill reportedly included concrete, sandstone, sand, construction rubble and earthen fill (Arcadis, 2017a). The industrial waste is estimated to be as close as 325 feet of the Mississippi River on the northern portion of the Site and within 40 feet of the southern Area C property boundary. Area C is approximately 14 acres in size and the footprint of the industrial waste area is estimated to be approximately 3.7 acres.

2.0 Report Review Barr’s review focused on a number of aspects related to the groundwater to surface water migration pathway, as discussed in the following sections.

Bob Fossum – Capitol Region Watershed District Evan Christianson, Jim Eidem, and Dan Fetter Ford Plant Area C Review October 1, 2018 2

Suitability of Analytical parameters The list of analytes for groundwater sampling appears to be fairly comprehensive. The TCAP operations and related waste disposal activities involves a long term history. According to Arcadis, there is limited information available regarding historical disposal practices. Based on similar auto assembly sites, the following additional groundwater analytical parameters may be helpful to assess potential risks to the river:

  

Per‐ and polyfluoralkyl substances (PFAS) 1,4‐dioxane Glycols

Per- and polyfluoralkyl substances (PFAS) are a group of contaminants that are an emerging concern and can be found in groundwater near disposal sites with histories similar to the Area C. The TCAP site historically operated nickel plating and metal etching operations (Arcadis, 2007). PFAS chemicals are known to have been used in such operations for corrosion prevention, mechanical wear reduction, and wetting agents/flume suppressants (ITRC, 2017). Wastes derived from the metal plating and etching operations containing PFAS may have been disposed in the Area C disposal area. The Mississippi River between Upper St. Anthony Falls and the St. Croix River is listed as impaired for Perfluorooctane Sulfonate (PFOS) in both fish tissue and the water column. The potential loading of PFAS to the Mississippi River from the Area C site should be evaluated.

Historically, 1,4-dioxane was used as solvent stabilizer. 1,4-dioxane may have been present in the solvents disposed within Area C, including in drums that reportedly remain within the waste today.

Glycols (anti-freeze) were presumably used at TCAP and may have been disposed in Area C. These analytical parameters should be considered by MPCA for future groundwater monitoring events.

Suitability of Groundwater Monitoring Network The monitoring network established for the Site may not fully allow for suitable characterization of the groundwater to surface water pathway.

Groundwater is implied to flow nearly parallel to the southern boundary of the Area C parcel and it appears that the monitoring network has been limited by staying within the southern property boundary.

Water quality samples from wells AMW-24 and AMW-25, along the southern boundary, identify groundwater with concentrations greater than Class 2B surface water standards for several contaminants, which could include potential migration off-site to the south.

Bob Fossum – Capitol Region Watershed District Evan Christianson, Jim Eidem, and Dan Fetter Ford Plant Area C Review October 1, 2018 3

Historically, a channel of the Mississippi River was located directly west of the industrial waste area, and below the current construction debris fill of Area C (Figure 2). This channel area was presumably cutoff from the main river channel during construction of Lock and Dam No. 1 and/or construction of the steam plant. The channel area was subsequently filled in as part of the disposal of waste within Area C. Remnants of the old channel are still visible in Hidden Falls Park from LIDAR imagery (Figure 2). The permeability of sediments within the old channel are unknown and the potential for this area to act as a zone of preferential groundwater flow has not been evaluated.

The potential southern extent of the groundwater impacts cannot be verified without additional monitoring wells located on the City of St. Paul parkland located directly south (Hidden Falls Park).

Groundwater may flow off-site to the south and eventually reach the Mississippi River.

Plume maps for the various contaminants of concern have not been presented. Based on the data presented in the Arcadis report, it is difficult to discern the lateral extent and center of plume mass for the various constituents. Additionally, the stability of the plume for the various constituents has not been established.

An updated cross section has been prepared through Area C along the presumed groundwater flow direction presented in the Acradis reports (see Figure 3). The St. Peter Sandstone thickness increases along the eastern edge of Area C and western edge of the main TCAP parcel (near Mississippi River Blvd).

The water table in this area resides within the St. Peter Sandstone and is hydraulically connected laterally to the unconsolidated alluvial sediments. It appears that Arcadis’s conceptual site model is to treat these hydrostratigraphic units separately in developing groundwater flow maps and hydraulic head contours.

Conceptually, groundwater flow within the St. Peter Sandstone migrating to Area C and the Mississippi River would be better characterized if these units were considered together. Groundwater samples from wells located near / up gradient of Area C, completed in the St. Peter Sandstone (e.g., AMW-05B, AMW07, AMW-29 and AMW-30), have consistently had metals concentrations (e.g., aluminum, cobalt, copper, nickel, and zinc) above Class 2B surface water standards. The migration of these metals within the St. Peter Sandstone and eventual discharge to the Mississippi River has not been fully evaluated.

The hydraulic connection between the unconsolidated alluvial sediments and the St. Peter Sandstone below the industrial waste has not been defined. Due to the relatively high permeability of the St. Peter Sandstone, and lack of evidence of a confining unit between the alluvial sediments and the St. Peter Sandstone, the potential exists for downward migration of contaminants below the industrial waste into the St. Peter Sandstone, both for dissolved phase constituents and potentially a DNAPL related to reports of solvent disposal. Well AMW-07 is the only well open to the St. Peter Sandstone near the edge of Area C. This well is located to the north (side-gradient) of the industrial waste and has had consistent concentrations of aluminum and cobalt concentrations above surface water quality standards since 2014.

Additional wells should be installed in the St. Peter Sandstone downgradient of the Area C waste disposal area and nested with monitoring wells screened in the alluvial sediments. These wells should be sampled to define the vertical extent of the plume at Area C and to determine vertical hydraulic gradients / vertical flow directions.

Hydraulic Conductivity Estimates Hydraulic conductivity estimates are not well documented and in some cases appear to have been derived incorrectly. In Section 3.2, a geometric mean hydraulic conductivity value is reported as 2x10-3 cm/sec, yet this value is less than the reported range of 5x10-3 cm/sec to 9x10-2 cm/sec. Hydraulic conductivity estimates were derived using grain-size distribution and the Hazen equation. Hydraulic conductivity estimates using this approach are rough approximations as best. The Hazen equation is generally appropriate for coarser sands; some of the reported d10 values are less than the generally accepted range of 0.1 to 3.0 mm for use with the Hazen equation (Fetter, 2001). Hydraulic conductivity is one of the key parameters for evaluating groundwater discharge and risk to the Mississippi River. Relying on rough approximations derived from the Hazen equation could potentially lead to inaccuracies in estimating groundwater discharge to the Mississippi River. Slug tests conducted in the site monitoring wells may result in more accurate hydraulic conductivity estimates.

Effectiveness of Concrete Cap (Parking Lot) Approximately fifty percent of the delineated area of industrial waste is covered by a concrete parking lot (referred to as a cap in the Arcadis report). The effectiveness of this parking lot at reducing infiltration of water through the waste has not been evaluated. However, the industrial waste has relatively high concentrations of DRO, GRO, and lead in sample taken above the water table, but the existing downgradient water table wells have relatively low concentrations for those constituent, which may indicate the cap is having a positive effect to reduce contaminant leaching from the industrial waste.

The long term effectiveness and durability of this parking lot is unknown. The current integrity of the parking lot and effectiveness at reducing infiltration should be evaluated and documented. A long term maintenance plan or construction of a cap designed specifically for long-term remedial purposes should be considered if the waste is to remain in place.

Effect of Mississippi River Flooding The report suggests that river flooding occurs laterally through the waste and its effect on the buried industrial waste is somewhat delayed relative to river stage changes. The MPCA has asked Ford to conduct additional groundwater monitoring to evaluate how the water table beneath the industrial waste fluctuates in response to changing river conditions. Transducers were deployed in four monitoring wells completed in the unconsolidated alluvial sediments (MW-19, MW-21, MW-25, and MW-26) and in one

monitoring well completed in the St. Peter Sandstone (MW-29) and the data is expected be reported later in 2018.

Influence of the Ford Dam (Lock and Dam no. 1) and Potential for Removal

With the closing of the Upper and Lower St. Anthony locks in 2015, commercial shipping in the Mississippi River gorge has ceased. The lack of shipping has resulted in the Army Corps of Engineers to evaluate if the Lower St Anthony Dam and the Ford Dam (Lock and Dam No. 1) should be decommissioned and removed. The potential effect on Area C resulting from removal of the Ford Dam has not been evaluated. Groundwater levels and flow directions could change, and the frequency of flooding could potentially increase without the dam. This could also affect nearby plumes related to the TCAP. Concern Regarding Drums of Industrial Waste Drums of industrial waste are reportedly present at Area C, representing a potential long-term and significant source of contaminants for the groundwater to surface water pathway. MPCA typically seeks removal of drummed industrial wastes, based on experience with other sites in Minnesota. Specific information is not available regarding the number of drums or contents, but could potentially include any of the typical waste streams generated at an auto assembly plant over many years (e.g., solvents, paint sludges/wastes, petroleum products, other automotive fluids, acids, caustic lye, and PCBs [in transformer fluid], etc.).

Drummed waste represent potential primary wastes that are subjected to migration as the drums weather.

Analytical testing from the industrial waste materials identify that more than 50% of the Industrial waste samples exceeds RCRA TCLP limits for lead, making it RCRA characteristically hazardous. There is no information to assess the condition of the drums currently, or the risk of future releases as containers might degrade. As a result, groundwater monitoring should continue as long as the drums and related wastes are present at Area C. Seeps

The report does not include discussion of seep distribution and / or seep sampling results in Area C. Seepage, if present along the river bank, would represent direct discharge into the river and should be sampled and accounted for in the discharge evaluation. If seeps are identified on the bluff east of Area C, they should also be sampled.

Groundwater / Surface Water Interaction

The Arcadis report evaluated the surface water to groundwater pathway and potential impact to the Mississippi River using a tiered approach recommended in the MPCA’s Surface Water Pathway Evaluation

User Guide (MPCA, 2006). While this guidance is proper for the Site, documentation within the Arcadis report is incomplete and in some areas indicates misapplication of the guidance and hydrogeology principals.

Calculation of groundwater discharge The plume discharge to the river was calculated incorrectly. Discharge should be calculated with the following equation (Darcy’s Law): ܳ ൌ ‫ܣܫܭ‬ Where: K is the hydraulic conductivity A is the cross sectional area of flow I is the hydraulic gradient.

Discharge in the Arcadis report was calculated as: ܳ ൌ ‫ܣݒ‬ Where: v is groundwater velocity A is the cross sectional area of flow,

The calculation used by Arcadis is appropriate for flow in an open pipe; it is not appropriate for flow within a porous media. The error should be corrected and the risk for all constituents reevaluated. Note that this correction will result in a lower discharge estimate to the river.

Mixing zone The lowest seven-day consecutive flow in a ten year span (i.e. 7Q10 discharge) of the Mississippi River was used to determine downstream concentrations of contaminants in the river. It is not clear if a mixing zone was considered for the analysis; as presented, the entire 7Q10 river discharge was used. The MPCA guidance has conflicting information on the requirements of a mixing zone. Section 4.2.1.2.2 of MPCA (2006) list guidelines for mixing zones, which include:

1. Mixing zone shall permit acceptable passageway for the movement of fish 2. Total mixing zone should contain no more than 25 percent of the cross‐sectional area and/or volume of the stream, and shall not extend over more than 50 percent of the stream width

To: From: Subject: Date: Page:

Bob Fossum – Capitol Region Watershed District Evan Christianson, Jim Eidem, and Dan Fetter Ford Plant Area C Review October 1, 2018 7

Using the entire 7Q10 discharge of the Mississippi River to determine downstream concentrations without a mixing zone may understate the risk to the surface water. Justification for not using a mixing zone should be provided or a mixing zone should be established and the risk for all constituents reevaluated.

Vertical Extent of Aquifer Contamination The vertical extent of the plume is not defined. The risk to the Mississippi River cannot be evaluated until the vertical extent of the plume has been established. Greater concentrations of contaminants may be present at depth and a thicker plume will affect estimates of groundwater plume discharge to the river. As discussed above, additional wells should be installed in the St. Peter Sandstone to delineate the vertical extent of the plume at Area C.

4.0 Summary and Recommendations The incomplete definition of vertical and horizontal extent of impacted groundwater at and downgradient of the waste in Area C is a potentially significant data gap. The Area C groundwater monitoring network primarily includes water table monitoring wells completed in the unconsolidated sediments (with the exception of two relatively shallow nested wells). The thickness of the unconsolidated sediments, elevation of the St. Peter Sandstone, and water quality at the base of the unconsolidated sediments and in the St. Peter Sandstone beneath and downgradient of the industrial waste are unknown. Further, water quality monitoring results indicate concentrations of multiple constituents (e.g., ethyl benzene, xylenes, cyanide) above Class 2B criteria and petroleum concentrations (reported as diesel range organics) greater than 10,000 micrograms per liter at the southern property boundary. The lack of vertical and horizontal delineation of groundwater impacts likely result in underestimates of contaminant flux into the Mississippi River and/or beneath the property located south of the Site.

Additional investigation, including the installation and sampling of deeper monitoring wells and/or vertical aquifer water quality profile borings is recommended. Figure 4 shows locations of recommended additional monitoring locations to fill in data gaps identified and discussed above. At each of these locations well nests are recommend, including wells at the base of the unconsolidated sediments and in the St. Peter Sandstone. Locations A and B are proposed to be located adjacent to existing wells AMW-26 and AMW-25 respectively. These additional wells are also shown on the cross section (Figure 3).

Locations C and D are proposed to be located offsite to the south in Hidden Falls Park. Location C is proposed to be within the historic Mississippi River Channel and location D near the bluff.

Other recommendations regarding the additions to the groundwater quality monitoring parameters (including PFAS and 1,4-dioxane), better characterizing hydraulic conductivity at the site, and correcting discharge estimates and mixing zone calculations are noted above.

Response to Comments on Area C Comprehensive Report from Capital Region Watershed District

The following is response to comments on the technical memo prepared by Barr on behalf of Capitol Region Watershed District on October 1st, 2018. The technical memo included some background and discussion in addition to comments so the sections that included specific comments or recommendations have been excerpted below.

Suitability of Analytical parameters The list of analytes for groundwater sampling appears to be fairly comprehensive. The TCAP operations and related waste disposal activities involves a long term history. According to Arcadis, there is limited information available regarding historical disposal practices. Based on similar auto assembly sites, the following additional groundwater analytical parameters may be helpful to assess potential risks to the river:

•

Per‐ and polyfluoralkyl substances (PFAS)

•

1,4‐dioxane

•

Glycols

Per- and polyfluoralkyl substances (PFAS) are a group of contaminants that are an emerging concern and can be found in groundwater near disposal sites with histories similar to the Area C. The TCAP site historically operated nickel plating and metal etching operations (Arcadis, 2007). PFAS chemicals are known to have been used in such operations for corrosion prevention, mechanical wear reduction, and wetting agents/flume suppressants (ITRC, 2017). Wastes derived from the metal plating and etching operations containing PFAS may have been disposed in the Area C disposal area. The Mississippi River

Page:

MEMO

between Upper St. Anthony Falls and the St. Croix River is listed as impaired for Perfluorooctane Sulfonate (PFOS) in both fish tissue and the water column. The potential loading of PFAS to the Mississippi River from the Area C site should be evaluated.

Historically, 1,4-dioxane was used as solvent stabilizer. 1,4-dioxane may have been present in the solvents disposed within Area C, including in drums that reportedly remain within the waste today.

Glycols (anti-freeze) were presumably used at TCAP and may have been disposed in Area C. These analytical parameters should be considered by MPCA for future groundwater monitoring events.

Response: PFAS, dioxane and glycols have not historically been included as potential contaminants of concern (COC) at the site and should not be included moving forward. 1,4-dioxane was used as a solvent stabilizer primarily in 1,1,1-TCA, which is not a primary COC at the TCAP site. Glycols do not have an applicable Class 2B Surface Water Standard (Class 2B standard) so evaluation of glycols would not result in a change to the ongoing feasibility study evaluation.

Hydraulic Conductivity Estimates Hydraulic conductivity estimates are not well documented and in some cases appear to have been derived incorrectly. In Section 3.2, a geometric mean hydraulic conductivity value is reported as 2x10-3 cm/sec, yet this value is less than the reported range of 5x10-3 cm/sec to 9x10-2 cm/sec. Hydraulic conductivity estimates were derived using grain-size distribution and the Hazen equation. Hydraulic conductivity estimates using this approach are rough approximations as best. The Hazen equation is generally appropriate for coarser sands; some of the reported d10 values are less than the generally accepted range of 0.1 to 3.0 mm for use with the Hazen equation (Fetter, 2001). Hydraulic conductivity is one of the key parameters for evaluating groundwater discharge and risk to the Mississippi River. Relying on rough approximations derived from the Hazen equation could potentially lead to inaccuracies in estimating groundwater discharge to the Mississippi River. Slug tests conducted in the site monitoring wells may result in more accurate hydraulic conductivity estimates.

Response: The calculated geometric mean from the CRA text should be 2x10-2 cm/s rather than 2x10-3 as noted in the report. Correcting the geometric mean conductivity value reported in the text does not affect the surface water calculations because the most conservative (highest) reported conductivity value of 9x10-2 cm/s was used in those calculations. Approximations, which are generally conservative, are included throughout the surface water pathway evaluation including in the hydraulic conductivity estimate and results in downgradient plume concentrations that are well below Class 2B standards.

Calculation of groundwater discharge The plume discharge to the river was calculated incorrectly. Discharge should be calculated with the following equation (Darcyâ&#x20AC;&#x2122;s Law): Q = KIA Where: K is the hydraulic conductivity A is the cross sectional area of flow I is the hydraulic gradient.

Discharge in the Arcadis report was calculated as: arcadis.com Page:

2/10

MEMO

Q=vA

Where: v is groundwater velocity A is the cross sectional area of flow, The calculation used by Arcadis is appropriate for flow in an open pipe; it is not appropriate for flow within a porous media. The error should be corrected and the risk for all constituents reevaluated. Note that this correction will result in a lower discharge estimate to the river.

Response: Arcadis agrees that the Darcy flux is more appropriate for calculating discharge to the river than the linear groundwater velocity. The calculations reported in Table 11 of the Tier 2 evaluation (Appendix N) were revised to use the Darcy flux values to calculate discharge to the river. Using the Darcy flux results in a corrected potential downstream contribution for each contaminant from Area C that is 30% of the originally reported contribution, as shown in the inset table below.

After incorporating this correction, all calculated values for the downstream contribution of impacts from Area C to the Mississippi River remain well below Class 2B standards.

Mixing zone The lowest seven-day consecutive flow in a ten year span (i.e. 7Q10 discharge) of the Mississippi River was used to determine downstream concentrations of contaminants in the river. It is not clear if a mixing zone was considered for the analysis; as presented, the entire 7Q10 river discharge was used. The MPCA guidance has conflicting information on the requirements of a mixing zone. Section 4.2.1.2.2 of MPCA (2006) list guidelines for mixing zones, which include:

1. Mixing zone shall permit acceptable passageway for the movement of fish 2. Total mixing zone should contain no more than 25 percent of the crossâ&#x20AC;?sectional area and/or volume of the stream, and shall not extend over more than 50 percent of the stream width

Using the entire 7Q10 discharge of the Mississippi River to determine downstream concentrations without a mixing zone may understate the risk to the surface water. Justification for not using a mixing zone should be provided or a mixing zone should be established and the risk for all constituents reevaluated. arcadis.com Page:

3/10

MEMO

Response: A mixing zone of 25% of the cross-sectional area was added to the calculation. The modified mixing zone and the revised calculation of groundwater discharge from the comment above were used to reevaluate the groundwater discharge to surface water pathway. The updated potential downstream contribution from Area C is included in the table below compared to the originally calculated contribution and the Class 2B standard. The updated mixing zone and groundwater discharge calculations will be carried forward when addressing comments below.

Suitability of Groundwater Monitoring Network Note: This comment includes several different assertions relating to the groundwater monitoring network.

For clarity, responses have been added within the comment to address each assertion when it is made.

Part 1: The monitoring network established for the Site may not fully allow for suitable characterization of the groundwater to surface water pathway. Groundwater is implied to flow nearly parallel to the southern boundary of the Area C parcel and it appears that the monitoring network has been limited by staying within the southern property boundary. Water quality samples from wells AMW-24 and AMW-25, along the southern boundary, identify groundwater with concentrations greater than Class 2B standards for several contaminants, which could include potential migration off-site to the south. The potential southern extent of the groundwater impacts cannot be verified without additional monitoring wells located on the City of St. Paul parkland located directly south (Hidden Falls Park). Groundwater may flow off-site to the south and eventually reach the Mississippi River.

Response: Groundwater elevation data collected during quarterly monitoring events and reported in the Area C quarterly reports has consistently shown that during typical non-flood conditions groundwater flow at Area C is generally to the west, approximately parallel to the southern property boundary rather than to the arcadis.com Page:

4/10

MEMO south. Under those conditions, Section 7.2.3.1.3.a of the MPCA guidance recommends using â&#x20AC;&#x153;the maximum ground water plume concentrations that are expected or are just upgradient prior to discharging to a surface water receptorâ&#x20AC;?. Consistent with that guidance and the identified flow direction, Arcadis used the highest detected concentration of each analyte identified in wells AMW-19, AMW-20, AMW-22 and AMW-22B, which are the wells closest to the Mississippi River.

Although it is not supported by the conceptual site model developed for Area C, the potential risk associated with concentrations at all wells on the site, including AMW-24 and AMW-25 to the south to the south of Area C could be estimated by including that analytical data in the Tier 1 and Tier 2 discharge calculations. Specifically, the resulting downstream concentrations were recalculated using the maximum concentrations for each constituent at all wells around Area C rather than just the wells closest to the discharge point. Also, additional data was included to capture groundwater analytical results collected through August of 2019. Expanding the width of the plume to account for the different groundwater flow direction was also considered, but the previous calculations already included a width of 850 feet which is the full potential width of Area C and would not be increased if the flow was assumed to be to the southwest. The updated potential downstream contribution from Area C is included in the table below compared to the previously calculated contribution and the Class 2B standard. These values also include the modified discharge calculations and mixing zone assumptions discussed above.

* Analyte no longer exceeds Tier 2 screening when using updated analytical results and well network The conservative inclusion of all wells in the data set results in a slight increase in the predicted concentration of some analytes and the addition of several new analytes to the analysis.

MEMO continue to be below applicable Class 2B standards with the exception of PCBs, which slightly exceed the standard. PCBs were detected in two of the 128 samples collected to date (Aroclor 1242 at a concentration of 0.14 ug/L at AMW-24 in May 2018 and Aroclor 1254 at a concentration of 0.073 ug/L at AMW-20 in August 2018). The limited detections of PCBs in groundwater around Area C indicate they are not consistently present in groundwater or discharged to the Mississippi River.

Despite the general lack of risk identified by the groundwater to surface water pathway evaluation, Ford agrees to the installation of off-site monitoring wells to provide additional information to the south of Area C. The location of the proposed off-site wells will be discussed after addressing additional comments below.

Part 2: Plume maps for the various contaminants of concern have not been presented. Based on the data presented in the Arcadis report, it is difficult to discern the lateral extent and center of plume mass for the various constituents. Additionally, the stability of the plume for the various constituents has not been established.

Response: Plume maps are not provided because the constituents exceeding applicable surface water standards are not consistently detected across the site. Concentration stability is being evaluated as additional data is collected.

Part 3: An updated cross section has been prepared through Area C along the presumed groundwater flow direction presented in the Arcadis reports (see Figure 2). The St. Peter Sandstone thickness increases along the eastern edge of Area C and western edge of the main TCAP parcel (near Mississippi River Blvd).

The water table in this area resides within the St. Peter Sandstone and is hydraulically connected laterally to the unconsolidated alluvial sediments. It appears that Arcadisâ&#x20AC;&#x2122;s conceptual site model is to treat these hydrostratigraphic units separately in developing groundwater flow maps and hydraulic head contours.

Conceptually, groundwater flow within the St. Peter Sandstone migrating to Area C and the Mississippi River would be better characterized if these units were considered together. Groundwater samples from wells located near / up gradient of Area C, completed in the St. Peter Sandstone (e.g., AMW-05B, AMW07, AMW-29 and AMW-30), have consistently had metals concentrations (e.g., aluminum, cobalt, copper, nickel, and zinc) above Class 2B standards. The migration of these metals within the St. Peter Sandstone and eventual discharge to the Mississippi River has not been fully evaluated.

Response: Metals detected in the St. Peter Sandstone are considered indicative of conditions upgradient of Area C, not representative of any contributions from Area C, and are outside the scope of this report. An evaluation of the contribution of metals in the St. Peter Sandstone to the Mississippi River was included in the 2018 Supplemental Groundwater Monitoring Report for the Main Parcel using the same groundwater to surface water evaluation method. Results of that evaluation demonstrated the metals detected in the St. Peter Sandstone would not result in an exceedance of any MPCA Class 2B standards.

Part 4: The hydraulic connection between the unconsolidated alluvial sediments and the St. Peter Sandstone below the industrial waste has not been defined. Due to the relatively high permeability of the St. Peter Sandstone, and lack of evidence of a confining unit between the alluvial sediments and the St. Peter Sandstone, the potential exists for downward migration of contaminants below the industrial waste into the St. Peter Sandstone, both for dissolved phase constituents and potentially a DNAPL related to

arcadis.com Page:

MEMO

reports of solvent disposal. Well AMW-07 is the only well open to the St. Peter Sandstone near the edge of Area C. This well is located to the north (side-gradient) of the industrial waste and has had consistent concentrations of aluminum and cobalt concentrations above surface water quality standards since 2014.

Additional wells should be installed in the St. Peter Sandstone downgradient of the Area C waste disposal area and nested with monitoring wells screened in the alluvial sediments. These wells should be sampled to define the vertical extent of the plume at Area C and to determine vertical hydraulic gradients / vertical flow directions.

Response: As discussed with the MPCA during development of this scope of work, no new wells were proposed for the St. Peter Sandstone because groundwater sampling from the unconsolidated alluvial sediments are the most likely to be impacted in the event of a release from Area C. Results of the investigation work completed to characterize the industrial waste did not provide any evidence to suggest a release of DNAPL. Additionally, as demonstrated by the consistent groundwater flow direction towards the Mississippi River, the river is a gaining stream during non-flood conditions, which means an upward hydraulic gradient would be present. Therefore, there is no groundwater transport mechanism that would result in migration of a dissolved phase deeper into the St. Peter Sandstone.

Although it is not supported by the conceptual site model developed for Area C, the potential risk associated with dissolved phase impacts in the St. Peter Sandstone discharging to the Mississippi River could be estimated by using additional conservative assumptions in the Tier 2 discharge calculations.

Specifically, the resulting downstream concentrations were recalculated using the thickness of both the unconsolidated overburden and the full potential thickness of the St. Peter Sandstone in the vicinity of Area C, which could be as great as 190 feet. These values also include the modified discharge calculations and mixing zone assumptions discussed above.

* Analyte no longer exceeds Tier 2 screening when using updated analytical results and well network As noted above, downward migration of DNAPL or dissolved phase impacts is not supported by the CSM developed for the Site, but even if the highest concentration of any compound that has been detected at any well at Area C was assumed to be present throughout the full thickness of the combined overburden and St. Peter Sandstone (209 feet) and across the full width of the site, the calculated downstream concentration in the Mississippi River would not exceed Class 2B standards for any compound except PCBs. As previously noted, the limited detections of PCBs in groundwater do not indicate a discharge to the river.

Despite the general lack of risk identified by the groundwater to surface water pathway evaluation under these conservative assumptions, Ford agrees to installation of bedrock monitoring wells to provide additional information to characterize the vertical gradient and potential impacts in the St. Peter Sandstone. The location of the proposed off-site bedrock wells will be discussed after addressing additional comments below.

Effectiveness of Concrete Cap (Parking Lot) Approximately fifty percent of the delineated area of industrial waste is covered by a concrete parking lot (referred to as a cap in the Arcadis report). The effectiveness of this parking lot at reducing infiltration of water through the waste has not been evaluated. However, the industrial waste has relatively high concentrations of DRO, GRO, and lead in sample taken above the water table, but the existing downgradient water table wells have relatively low concentrations for those constituent, which may indicate the cap is having a positive effect to reduce contaminant leaching from the industrial waste.

The long term effectiveness and durability of this parking lot is unknown. The current integrity of the parking lot and effectiveness at reducing infiltration should be evaluated and documented. A long term maintenance plan or construction of a cap designed specifically for long-term remedial purposes should be considered if the waste is to remain in place.

Response: Potential use of the concrete cap as a means to limit long-term infiltration will be considered as part of the Feasibility Study if needed.

Effect of Mississippi River Flooding The report suggests that river flooding occurs laterally through the waste and its effect on the buried industrial waste is somewhat delayed relative to river stage changes. The MPCA has asked Ford to conduct additional groundwater monitoring to evaluate how the water table beneath the industrial waste fluctuates in response to changing river conditions. Transducers were deployed in four monitoring wells completed in the unconsolidated alluvial sediments (MW-19, MW-21, MW-25, and MW-26) and in one monitoring well completed in the St. Peter Sandstone (MW-29) and the data is expected be reported later in 2018.

Response: Flood monitoring is ongoing. Results will be included in the Area C quarterly reports.

MEMO

Influence of the Ford Dam (Lock and Dam no. 1) and Potential for Removal

With the closing of the Upper and Lower St. Anthony locks in 2015, commercial shipping in the Mississippi River gorge has ceased. The lack of shipping has resulted in the Army Corps of Engineers to evaluate if the Lower St Anthony Dam and the Ford Dam (Lock and Dam No. 1) should be decommissioned and removed. The potential effect on Area C resulting from removal of the Ford Dam has not been evaluated. Groundwater levels and flow directions could change, and the frequency of flooding could potentially increase without the dam. This could also affect nearby plumes related to the TCAP. Response: Evaluation of groundwater data and development of a Feasibility Study is being completed for the conditions that currently exist and are reasonably expected to exist in the near future. If major changes like removal of Lock and Dam No. 1 occur then the effect of that change on Area C would be evaluated at that time.

Concern Regarding Drums of Industrial Waste Drums of industrial waste are reportedly present at Area C, representing a potential long-term and significant source of contaminants for the groundwater to surface water pathway. MPCA typically seeks removal of drummed industrial wastes, based on experience with other sites in Minnesota. Specific information is not available regarding the number of drums or contents, but could potentially include any of the typical waste streams generated at an auto assembly plant over many years (e.g., solvents, paint sludges/wastes, petroleum products, other automotive fluids, acids, caustic lye, and PCBs [in transformer fluid], etc.).

Drummed waste represent potential primary wastes that are subjected to migration as the drums weather.

Analytical testing from the industrial waste materials identify that more than 50% of the Industrial waste samples exceeds RCRA TCLP limits for lead, making it RCRA characteristically hazardous. There is no information to assess the condition of the drums currently, or the risk of future releases as containers might degrade. As a result, groundwater monitoring should continue as long as the drums and related wastes are present at Area C. Response: No additional information about the potential presence of drummed waste is available. The potential need for a groundwater monitoring program will be included in the forthcoming Feasibility Study.

Seeps

The report does not include discussion of seep distribution and / or seep sampling results in Area C. Seepage, if present along the river bank, would represent direct discharge into the river and should be sampled and accounted for in the discharge evaluation. If seeps are identified on the bluff east of Area C, they should also be sampled.

Response: No seeps have been identified along the riverbank. Seeps identified on the bluff east of Area C were evaluated in the Technical Memorandum to Summarize the Seep and River Sampling Events dated February 22nd, 2011.

Vertical Extent of Aquifer Contamination The vertical extent of the plume is not defined. The risk to the Mississippi River cannot be evaluated until arcadis.com Page:

9/10

MEMO

the vertical extent of the plume has been established. Greater concentrations of contaminants may be present at depth and a thicker plume will affect estimates of groundwater plume discharge to the river. As discussed above, additional wells should be installed in the St. Peter Sandstone to delineate the vertical extent of the plume at Area C. Response: This comment is addressed above in Part 4 of the Suitability of Groundwater Monitoring Network comment.

Conclusions and Recommendations Based on review of the comments received on the Area C Comprehensive Report additional monitoring wells will be installed at the locations shown in the attached Figure 1. The proposed wells will have the following objectives: •

AMW-27 will be installed at the water table to provide groundwater analytical data in the area where a historical river channel has been identified to determine if the fill within that channel is acting as a potential preferential flow path for groundwater.

•

AMW-28 will be installed at the water table to provide analytical data further south of Area C to determine if impacts identified at AMW-24 and AMW-25 are potentially flowing south.

•

AMW-19B, -26B and- 27B will be installed in the unconsolidated overburden just above bedrock to provide additional data in the deeper portion of the unconsolidated deposits.

•

AMW-19R, 26R, 27R and 28R will be installed approximately 30 feet into bedrock to provide additional analytical and hydraulic gradient data in the St Peter Sandstone.

The proposed wells will be added to the existing groundwater monitoring program. At least one of the existing groundwater transducers will be relocated to a bedrock well to begin collecting long-term hydraulic gradient data.

Technical Memorandum To: From: Subject: Date: Project:

Bob Fossum – Capitol Region Watershed District Evan Christianson, Jim Eidem, and Dan Fetter Ford Plant Area C—Update Review Summary December 17, 2019 23621278.00

This technical memorandum presents Barr’s review of Arcadis’s October 23, 2019 Memo providing

responses to Barr’s Oct. 1, 2018 memo for the Ford Area C disposal area. Barr’s has reviewed several documents related to Area C disposal area at the Ford Motor Company’s, Twin Cities Assembly Plant (TCAP) in St. Paul, Minnesota. The documents reviewed included:

• • • • •

Arcadis 2011 seep and surface water sampling summary (Arcadis, 2011) Area C - Comprehensive Site History and Investigation Report dated May 2017 (Arcadis, 2017a) Arcadis Groundwater Sampling Summaries for 2nd Quarter 2018 (Arcadis, 2018) and 1st and 2nd Quarter 2019 (Arcadis, 2019a) Arcadis’s Response to Comments on Area C Comprehensive Report from Capital Region Watershed District (Arcadis, 2019b) 2017 comment letters to MPCA (and MPCA’s responses) from Capitol Region Watershed, Friends of the Mississippi River, National Park Service, and District City of St. Paul/Landmark Environmental

The reports and comments address a variety of topics, but Barr’s 2018 review and comments primarily related to the groundwater to surface water migration pathway at Area C near the Mississippi River.

Recognizing the relatively long time passing between new sampling events, reporting, and the recent

Arcadis response to Barr’s 2018 memo, the attached table and figures have been prepared to summarize

discussion topics.

Table 1 Status of Barr’s Discussion Topics Area C Disposal Area, Former Ford Plant, St. Paul Minnesota

Topic from Barr’s Oct. 1, 2018 Memo 1. Additional analytical parameters:

Response in Arcadis’s October 23, 2019 Memo

Barr’s updated comment (Dec. 2019)

•Per- & polyfluoralkyl substances (PFAS)

Do not include these going forward since parameters have not historically been included as potential contaminants of concern (COC)

PFAS is an emerging contaminant and by that definition has not been a COC for historical investigations at most sites, and so that isn’t sufficient reason to exclude it from testing now.

Recommend PFAS sampling as part of groundwater monitoring.

•1,4-dioxane

Not warranted based on limited presence of 1,1,1-Trichloroethane. 1,4-dioxane was used as a solvent stabilizer primarily in 1,1,1-TCA, which is not a primary COC at the TCAP site.

Acknowledged. The request was based on ‘strong solvent odors’ indicated in the borings logs related to the industrial waste. MPCA has clarified that the odors are believed to be associated with hydrocarbon solvents (e.g., mineral spirits/DRO) rather than chlorinated solvents, and there is limited presence of chlorinated solvent constituents in groundwater samples

•Glycols

Glycols do not have an applicable Class 2B Surface Water Standard so evaluation of glycols would not result in a change to the ongoing feasibility study evaluation.

Acknowledged.

2. Expand groundwater monitoring network, including locations in Hidden Falls park south of Area C and vertically nested locations at Area C

Provided updated justification for current monitoring network and updated discharge calculations for river based on existing data.

Do not acknowledge concerns with vertical gradients or southern flow potential, but Agrees to expand monitoring network

It is not clear why Arcadis choose different locations at 27 and 28 rather than proposed by Barr on the south side of Area C at locations C and D (see attached figures). Proposed locations C and D are recommended and could be accessed.

P:\Mpls\23 MN\62\23621278 Ford Plant - Area C Review\WorkFiles\2019 Update Memo\Final\Table 1-Updated Summary of Discussion Topics.docx

Table 1 Status of Barrâ&#x20AC;&#x2122;s Discussion Topics Area C Disposal Area, Former Ford Plant, St. Paul Minnesota We also recommend river elevations be based on US ACE gage data at the dam. See also response 7 below 3. Correct/update hydraulic conductivity (HC) estimates, conduct slug tests

Corrections made. No further estimate or measurement of HC necessary based on overall conservative nature of groundwater to surface water pathway evaluation

Accurate estimates of hydraulic conductivity from slug testing would help support the FS evaluation process and the next two topics. The expanded network in 2 above may lead to further evaluations and outcomes.

4. Groundwater discharge calculation

Updated. Continues to indicated river SWQS are met

These should be updated as data is available from expanded network and monitoring occurs during flood conditions, and it should be incorporated into future monitoring

5. Mixing Zone calculation

Updated. Continues to indicate river SWQS are met

These should be updated as data is available from expanded network and monitoring occurs during flood conditions, and it should be incorporated into future monitoring

6. Long-term Effectiveness of Concrete Cap (Parking Lot)

Will be evaluated in FS

Acknowledged. An opportunity to review and comment on the draft FS is also requested.

7. Effect of Mississippi River Flooding

Flood monitoring is ongoing. Results will be included in the Area C quarterly reports

A reverse in groundwater flow direction was indicated in the March 2019 data, including downward gradients from water table wells compared to St. Peter wells, and water table flow direction to the southeast. (also see next comment)

P:\Mpls\23 MN\62\23621278 Ford Plant - Area C Review\WorkFiles\2019 Update Memo\Final\Table 1-Updated Summary of Discussion Topics.docx

Table 1 Status of Barrâ&#x20AC;&#x2122;s Discussion Topics Area C Disposal Area, Former Ford Plant, St. Paul Minnesota 8. Influence of the Ford Dam (Lock and Dam no. 1) and Potential for Removal

Evaluation of groundwater data and development of a Feasibility Study is being completed for the conditions that currently exist and are reasonably expected to exist in the near future. If major changes like removal of Lock and Dam No. 1 occur then the effect of that change on Area C would be evaluated at that time.

The uncertainty of future river conditions (increased flood events and potential removal of the lock and dam) should be discussed in the feasibility study for Area C when assessing remedial alternatives that involve the continued long term presence of the waste in Area C.

9. Concern Regarding Drums of Industrial Waste

No additional information about the potential presence of drummed waste is available. The potential need for a groundwater monitoring program will be included in the forthcoming Feasibility Study.

The FS process should not be finalized until results from the expanded groundwater monitoring network are available. An opportunity to review and comment on the draft FS is also requested.

10. Seeps

No seeps have been identified along the riverbank. Seeps identified on the bluff east of Area C were evaluated in the Technical Memorandum to Summarize the Seep and River Sampling Events dated 2/22/2011.

The seep sample was upstream of the dam. It is not clear if seeps have been, or could be, identified near Area C.

11. The vertical extent of the plume is not defined

See Suitability of Groundwater Monitoring Network above in 2.

See 2.
