What's the difference between

Gorman-Rupp pumping stations and enclosures and others in

the market? About five to twenty years, to be exact. The difference

starts with an exclusive, 5-year station warranty on our packaged pumping system (compared to 90-day and oneyear warranties

offered by other manufacturers).

Pre-engineered, factory-tested and ready for installation, our

packaged pumping system features controls, piping, valves,

and Super T Series® pumps pumps that offer unsurpassed reliability in solids handling

A recent report pointed out that the average Canadian water and sewage pipe network has used up to 50% of its predicted life. Our water pipes are being replaced at a rate of six tenths of one percent, meaning that on average, each pipe would be replaced every 150

years. Walkerton is a sombre warning of the potential price, human and fis cal, of infrastructure neglect. The

McGuinty Liberal government in Ontario recently switched $60 million from its health budget to infrastruc ture. Noble as this seems, it is still $4 million short of the $64 million spent investigating the Walkerton drinking water tragedy. Had a mere fraction of these monies been spent on infrastruc ture rehabilitiation and disinfection

equipment, the disaster could have been avoided by an investment of a few thousands, not millions. â–

$400 million committed for Nova Scotia

tar ponds clean-up

Stephen Owen, Minister of Public Works and Government

Services Canada, David Anderson, Minister of the Environment and John Hamm,

Premier of Nova Scotia, announced up to $400 million in funding for the clean-up of the Sydney Tar Ponds and Coke Ovens. The province will provide $120 million and the Government of

Canada will contribute up to $280 mil lion.

The minister and the premier signed a memorandum of agreement in May committing their governments to a clean-up that will use proven, effective

technologies to safely destroy the worst contaminants and treat the

remaining material before encapsulat ing both sites with an engineered con tainment system. The sites will be restored and land

scaped in a manner consistent with their natural surroundings and future use. Upon completion of the clean-up, the province will assume ownership of the properties. The project will proceed on several fronts over the coming months. The removal of the Domtar tank will con

Ontario's Interim Guidelines for the Production

and Use ofAerobic Compost in Ontario was pub lished as a temporary guideline in 1991 to assist in the selection and approval of appropriate aero bic composting methods and the production of quality compost. The guideline establishes criteria for metals, pathogens, foreign matter and maturity for a compost prod uct before it can be used in an unrestricted manner.

The metal criteria in the Ontario guidelines were devel oped based on the objective of not significantly affecting the background soil level when used in an unrestricted manner. It was noted in the guideline that the compost quality criteria requirements would be modified as new and updated information became available. The Canadian Council of Ministers of the Environment

(CCME) researched and published a national compost guideline titled "Guidelines for Compost Quality (CCME106E March 1996). The CCME guidelines were developed based on several objectives including the protection of public health and the environment across the country. It was also to encourage source separation of Municipal Solid Waste (MSW) to produce a high quality compost. Other provincial jurisdictions have adopted the CCME guideline. The Ontario Ministry of the Environment had proposed to harmonize with the CCME standard for metals in 1998.

This initiative was part of a comprehensive waste manage ment regulatory review proposal which was posted for pub lic comment on the EBR (RA8E0023-1998). At that time, respondents who commented were supportive of this part of the proposal. However, the Ministry did not proceed with the comprehensive waste management proposal (RA8E0023-2002). The Ministry's interim compost guideline used known upper levels of soil background concentrations to develop metal criteria for compost. Experience has shown that in some instances these criteria may be overly restrictive. The CCME used a combination of soil background concentra tions and concentrations achievable using existing com12 Environmental Science & Engineering,June/July 2004

posting technology for source separated organics to estab lish their criteria. The CCME numbers were limited at the

top end by the CCME effects-based soil quality criteria to protect public health and the environment. The Ministry is proposing to harmonize its criteria for metals with that ofthe CCME guideline. The proposed cri teria for the eleven metals are described below (all values based on dry weight): • Arsenic: proposed criteria is 13 mg/kg, • Cadmium: proposed criteria is 3 mg/kg,(unchanged) • Chromium: proposed criteria is 210 mg/kg, • Cobalt: proposed criteria is 34 mg/kg, • Copper: proposed criteria is 100 mg/kg, • Lead: proposed criteria is 150 mg/kg,(unchanged) • Mercury: proposed criteria is 0.8 mg/kg, • Molybdenum: proposed criteria is 5 mg/kg, • Nickel: proposed criteria is 62 mg/kg, • Selenium: proposed criteria is 2 mg/kg,(unchanged) • Zinc: proposed criteria is 500 mg/kg.(unchanged) The existing criteria for the same 11 metals are: • Arsenic: 10 mg/kg, • Cadmium: 3 mg/kg, • Chromium: 50 mg/kg, • Cobalt: 25 mg/kg, • Copper: 60 mg/kg, • Lead: 150 mg/kg, • Mercury: 0.15 mg/kg, • Molybdenum: 2 mg/kg, • Nickel: 60 mg/kg, • Selenium: 2 mg/kg, • Zinc: 500 mg/kg. This harmonization of the metal criteria allows for the

production of a high quality compost and enables easier use and marketing of the end product. Comments should be directed to: Sr. Program Advisor, Waste Management Policy Branch, 135 St. Clair Ave. West, 7th Floor, Toronto, Ontario, M4V lP5,Tel:(416) 314-9404 Fax:(416) 325-4437. ■

Kamloops Augering Ltd., of Trail,

British Columbia, is a trenchless pipe rehab contractor using several trench less techniques including directional drilling, pipe ramming, auger boring, and pipe bursting.

municipalities in Canada have experienced the kind of rapid population and eco nomic growth that the Region of Peel has. With the population increasing threefold during this time, from about 330,000 to over one million residents and still growing, the municipality places a high priority on ensuring that new infrastructure expenditures are long-term investments. The residential community, while significantly contributing to the growth, is not the only group of people moving into Peel. The business com munity is also growing each year, mak ing Peel an integral part of the eco nomic engine that drives industry within the Greater Toronto Area, the Golden Horseshoe and South-Western Ontario. One reason Peel has been success

ful in attracting new industry is because of its proximity to key Canadian and US markets. Rail, ship, and air transport services are easily accessible and reliable in Peel and

municipal infrastructure such as road way networks, water and sewer servic es are in place and readily available. Located on the shores of Lake

Ontario, the Region of Peel has direct access to an abundant supply of quali ty drinking water. Unquestionably,

having a secure source of water is one service that is critical for healthy growth and development to occur in any community, as is the ability to finance the delivery of that service. With this in mind, the Region of Peel began discussions in 2002 to expand its Lakeview Water Treatment Plant (LWTP). Both Regional Council and senior management established key criteria for current and future expansions at the site. It was impera tive that the expansion remain within the existing footprint of the plant, pro duce the highest quality drinking water possible at a reasonable cost, and allow for sufficient capacity to service future needs and opportunities. After an extensive pilot program, and in consultation with engineering and design firm CH2M HILL, the Region of Peel decided to implement a new, innovative, multi-barrier approach at its LWTP, using ozonation, biologi cally active carbon (BAC) contactors and hollow-fibre ultrafiltration (UF) membranes.

Upon completion of the expansion, this project will be the largest lowpressure, UF membrane plant in the world with a summer capacity of over 300 ML/d (80 mgd) and a cold water (2°C) capacity of 262 ML/d (69 mgd). Daily water treatment capacity of the plant will rise from the current 560

18 Environmental Science & Engineering,June/July 2004

ML/d (148 mgd) to 820 ML/d (216 mgd). Products considered for installation at the LWTP needed to demonstrate

reliability and longevity. Three leading membrane suppliers were invited to participate in a comprehensive pilot program to test the performance of their products for factors such as solids and pathogen removal. At the conclu sion of the study, the ZENON ZeeWeedÂŽ 1000 membranes showed

the highest quality technical solution at the most reasonable cost.

Drinking water treatment with lowpressure ultrafiltration membranes is becoming increasingly more common throughout North America, and many municipalities have adopted ZENON technology to serve their communities. Reference sites in Collingwood, Ontario (32.5 ML/d, 8.6 mgd); Sudbury, Ontario (37.8 ML/d, 10 mgd) and Racine, Wisconsin (189 ML/d, 50 mgd) were examined closely by Peel staff during the decision-making process.

In determining the best value for Peel, each supplier was also asked to submit a technical proposal which was assigned a relative performance factor. The results from this step were used to adjust each supplier's cost proposal which considered both capital and 20year operating costs. Other factors

The Lakeview WTP will incorporate the latest version of ZENON ZeeWeedÂŽ membranes and will ben

"The ozone and BAG pretreatment will deliver a consistent quality feed water to the membranes with turbidity below 2.0 NTU, 95 per cent of the time, with total suspended solids below 5.0 mg/L (maximum of 40 mg/L)and DOG ranging from 1.0 - 5.0 mg/L," said Director of Water and Wastewater Treatment Mark Schiller.

During pilot testing, the pretreat ment contributed to more efficient

membrane functioning with longer cleaning intervals and trouble-free operation during raw water variability. Overall, the pretreatment will benefit the system with more consistent per meate quality, reduced energy costs.

Oil/Water Separation

Achieving oil free bilge water discharges from ships

In the void space below the engine

room floor of commercial ships,

condensation, wash-down water,

cooling water and oil leaks accu mulate. This bilge water can be dis charged overboard while "under way", provided it is processed through approved bilge water separators and verified by an approved oil content meter to Transport Canada stated lim its. For inland waters (rivers and lakes) the limit is 5 ppm; for "outside" waters the limit is 15 ppm. The challenges to compliant bilge water discharges come from physics as well as chemistry. In industrial appli cations there is generally a limit to how many different oils may be mixed with outflows, whereas on a ship anything can drop into the bilge. Ships have dif ferent engines installed, running on different fuels and using different lube oils. There is hydraulic oil, there is grease and then there are the water

treatment chemicals, cleaners, etc. To

top it all off, the moving ship then mixes the oily bilge water. The first bilge water regulations were introduced in 1973 with 100 ppm effluent quality. In 1978 this was amended to 15 ppm for coastal waters and in 1993 the 15 ppm limit became the universal limit; only in Canada do we have 5 ppm for inland waters. To be able to discharge treated bilge water, the oil content in the effluent has to be below the allowed limit. A

ship owner can choose between invest ing in equipment that can handle any thing, or he can make the crew respon sible to get bilge water overboard. The latter option is the only cost-effective and reliable alternative. Preventing uncontrolled oil leaks saves costs and

it makes bilge water processing possible. The efforts by the crew are directed towards the elimination, or at least reduction of emulsification of the oil

and water mixture. This is prevention of chemical emulsions from detergents and surfactants, and the prevention of mechanical emulsions.

Chemical emulsions are primarily caused by detergents, therefore ships have changed to the use of"fast break ing" cleaners. These products "tem porarily" emulsify oil, then let the oil float free for gravity separation or removal in the oily water separator (OWS). These "fast breaking" cleaners are mostly biodegradable; they have to be non toxic and cannot be flammable

He has over 20 years of project management and engineering experience on environmental, municipal and transportation projects, and is the Associate Manager of the firm's Ottawa regional office.

Oil/Water Separation Mechanical emulsions are basically the result of kinetic energy. A pressure leak or a drop falling into the bilge will cause finer oil dispersion than the laws of physics can reverse. The fractured oil drops rising slowly to the surface don't have the same energy to coalesce as what split them apart. To get "sepa rable" bilge water, crews limit the mix ing of oil and water. To avoid emulsification through the ship's motion, skim mers are used to remove floating oil. Today the effluent quality is veri fied by oil content meters(OCM)with sophisticated light scattering measur ing systems. Their ability to detect very small oil drops, registers mechan ical as well as chemical emulsions.

With their accuracy, discharge quality has improved, requiring crews to be vigilant in the prevention of oily water and irmovative in the processing of bilge water. Whereas before ships could dis charge overboard in a single pass through the International Maritime Organization (IMG ) approved oily water separator because of the less reliable meters, this is not possible

summo product division

today. The modern OCM no longer ignores the finer oil particles and reg isters total oil content more accurately. To be able to get the bilge water overboard, cascaded systems are com monly used, where bilge water is trans ferred into a holding tank, decanted and the oil removed. The oily water mixture is then processed through the IMO approved OWS and discharged, if the oil content is below the alarm set

point. Depending on the type of ship, fuel used and shipboard practices, this basic, cascaded system is then expand ed and modified, to achieve the eompliant effluent quality. If the choice of cleaners, catch-alls, skimmers and other initiatives fails to produce the required effluent quality, then polish ing filters are generally used to clean the effluent to measurable, clean dis charges. Is 15 ppm oil content a threat? One way to look at 15 parts per mil lion is to equate it to roughly one 2.5 mm oil drop in I litre of water. One such drop would readily separate; therefore oil needs to be finely distrib

uted to form a stable mixture. Such a

homogeneous 15 ppm mixture is com posed of oil drops evenly dispersed in the effluent, with each oil particle spaced about 40 times its diameter from the next one. Measuring oil eontent of such an oil distribution is simi

lar to looking at the rainbow. Difficulties in measuring this 15 ppm oil dispersion arise as background tur bidity increases, like dust or smog for the rainbow.

A ship "making way" at 6 KN,trav els about three metres per second (10.8 km/hr). A typical Great Lakes freighter carrying 24,000 tons of goods, processes bilge water through a 3.5

m^/hr OWS, whieh is equal to 1 litre per second,for about 8 hours in 7 days. Thus it discharges at maximum allow able effluent quality, one oil drop equivalent over 3 metres traveled. Commercial ships disperse the effluent over the length of the Seaway, i.e. 3,700 km, en route, not in port.

Cold climate lagoon-based ammonia reduction been a difficult problem to solve. During the past five years, a collaborative effort with a number of technology suppliers, scientists and engineers has resulted in the suc cessful retrofit of six lagoon sites for the purpose of ammo nia reduction. These sites included municipal lagoons, agri cultural hog manure lagoons, and landfill leachate ponds. Three of these systems have ice-covered conditions during


winter months with water temperatures at 1 °C, and all sys tems have water temperatures that fall below 5°C during winter months.

Nitrification is enhanced at higher pH levels. pH levels of 7.5 to 8.5 are ideal, although nitrifying bacteria can adapt outside of this range. Nitrification will also produce acids.

Watershed Strategies is important to the Niagara Region, its residents, and its neighbours. It is for this reason that a template for a Regional Report Card was developed. The report cards are meant to demonstrate relative levels of improvement or degradation in the six theme areas developed as part of the NWQPS. In order to make these comparisons, baseline monitoring will need to be established for each of the mon itoring areas. Following this initial monitoring, grades can be assigned based on the level ofimprovement in each area. Periodic updating of the strategy will be required in order to incorporate the findings of the monitoring plan and to address new approaches which arise. Recommend ations were made that the strategy be updated on a fiveyear basis. Integration of NWQPS with provincial planning framework NWQPS is a significant undertaking that will address the need for source protection planning recommended in Part One and Part Two reports of The Walkerton Inqiiiiy and anticipated as a legislative requirement by the Province. It is important that the NWQPS meets the source protection planning requirements and, at the same time, be imple mented through a framework that meets the specific requirements of the Niagara Region, area municipalities, and other key stakeholders. In April 2003, the provincial government's Advisory Committee





Planning released their final report entitled. Protecting Ontario's Drinking Water: Toward a Watershed based Source Protection Planning Framework. NWQPS essentially, is the foundation for a Source Protection Plan. The plan has been developed, however, to this point, without the benefit of the province's Source Protection Planning Framework. The implementation framework provides a structure that is in conformance with the requirements put foward in the province's Source Protection Planning Framework and will ensure that the recommendations that were put forward in the two Walkerton Inquiry reports are addressed. NWQPS priorities Implementation of the NWQPS is now being directed by an Implementation Committee that has the mandate to ini tiate the implementation priorities and to determine the ultimate framework structure that will provide for the longterm management of the Strategy. In the proposed Framework for Implementation, it is suggested that an Implementation Team be set up to conduct the respective Action Programs that support the NWQPS. Specifically, the Implementation Team will be responsi ble for the direct actions being implemented directly as a result of the NWQPS. In addition, the Implementation Team will need to be informed by a host of indirect actions, which are, or will be, undertaken by other stakeholders across Niagara. Some examples of important direct actions include: • Taking stock of existing environmental monitoring pro grams, assessing data gaps, and establishing new partner ships along with harmonized standards; • Standardizing land use regulations and policies across the Region; • Conducting a pilot project in an appropriate urban centre to determine stormwater retrofit opportunities;

• Developing maps of all significant water takings (link to groundwater study); • Establishing a Rural Water Quality Demonstration proj ect (link to benefits to downstream urban users); • Conducting user surveys to characterize recreational use, attitudes, and opinions; • Preparing Local Area report cards and setting up local interest groups; and • Developing relational database actions, status, and other benefits, etc. Some equally important indirect actions include: • Petitioning area municipalities, agencies, and stakehold ers on current and planned initiatives; • Developing an information transfer protocol; • Supporting and participating on complementary initia tives by way of information transfer; and • Setting up an Advisory Committee structure. Implementation of the NWQPS will continue in 2004 and into 2005, with many actions items being undertaken and many more stakeholders becoming involved to ensure that the vision of Water for Life becomes a reality.

Environmental Laboratories

Environmental labs measure the effectiveness

of conforming to international standards ctive conformance to interna






ISO/IEC9001:2000 is intend-

Led to help organizations con

sistently produce a quality product

(material or service) and instill a cul ture of continual improvement in their operations. The fact that registration to ISO standards is a growing phenome non (greater than 500,000 worldwide)

strongly suggests that the process is effective.

But the question must be asked: Is it successful because it measurably improves the performance of the oper ation, or is it successful because it has

become a powerful mar keting tool - a cost of doing business? The ana lytical laboratory indus try in Canada is an excel lent case study in the true

and reagents, and numerous other questionable practices. This situation was not helped by the practices of the predominant client for many of these services, the engineer ing community. Too often, the decision on what laboratory to use was based solely on two criteria, cost and turn around time. The perception being pre sented was that the signed report was more important than the quality of the results on the report. Presumably, some clients felt that having a signed report absolved them of any liability resulting from erroneous data. We now know that legal liability cannot be rationalized this easily.

CAEAL-registered laboratories could also expect increased business as (hopefully) clients preferentially selected registered laboratories over non-registered laboratories. The first program to be established by CAEAL was a Proficiency Testing (PT) program in which samples were sent to member laboratories twice per year. A laboratory's performance for each parameter was evaluated against all other laboratories. Successful par ticipation resulted in proficiency certi fication on a parameter level basis. In 1993 the accreditation program was added. This program, for which PT participation is mandatory, assesses a laboratory's conformance to ISO/IEC 17025 (updat •Accredited (2001)

knowledge of analytical chemistry (or not) could set themselves up to provide analytical chemistry services to the general pub lic. This resulted in, not only a great diversity in quality between laborato ries, but often a great diversity in qual ity within the same lab. The highly competitive nature of the analytical chemistry market and the general lack of accountability occasionally resulted in laboratory practices that would not be considered acceptable by today's

standards. These included the use of

methods that were not properly vali dated, the use of non-qualified or poor ly-trained staff to perform testing, skipping of critical steps in analytical processes, use of out of date standards

In 1989, the laboratory community cooperated to form the Canadian Association



Analytical Laboratories (CAEAL). The main goal of the association was to improve the quality of environmen tal information in Canada. It is also fair to state that individual laboratories

were motivated by an attempt to level the playing field amongst analytical laboratories and a desire to improve how the laboratory industry was being perceived by the general public. Membership required a laboratory to abide by a set of by-laws, a code of conduct, and client confidentiality.

these programs, when properly imple mented and maintained, actually result in a measurable improvement in the quality of analytical results or whether their benefit is limited to their market

ing value.

The CAEAL proficiency testing program has been in operation since 1989 and has grown in size and scope ever since. This extensive database is a

valuable tool for evaluating the effect of various factors on laboratory per formance. In 2004, A. Morris and D. Macey published a paper clearly demonstrating that accredited labora tories perform better on proficiency testing samples than non-accredited

Environmental Laboratories laboratories (Accred Qual Assur 9:52-54). Given that labo ratory accreditation is contingent on demonstrating confor

mance to an international standard, this result is not unex pected. This leads to the question; If accreditation results in

improved performance, is there an added value to profi ciency testing or is this program superfluous? Again, the CAEAL proficiency testing database contains the informa tion necessary to answer this question. The database was queried to retrieve all laboratory/parameter combinations where first time PT participation started after October 1994

(5 87

and participation continued for at least ten consecutive PT rounds. For each laboratory/parameter combination, the first participation was assigned to study one. In total, 29,480 individual scores were used in this examination.

When the average PT scores were plotted, the trend was obvious. Average performance (as measured by PT score) improved over the first few rounds, after which it leveled off. Since this data-set includes accredited labs, nonaccredited labs and labs that obtained accreditation within

the ten study window, it can be stated with confidence that the observed trend is due to PT participation, not due to other factors that may affect quality. This phenomenon is supported by observations made for clinical laboratory PT programs. For example, in 1994, PT participation was mandated for clinical laboratories in the United States. This resulted in a decreased percentage of acceptable PT scores, due to the influx of a large number of

In the aftermath of the Walkerton tragedy, provincial governments enacted new legislation and regulations with the goal of protecting the safety of drinking water.

Environmental Laboratories 17025. Although this is a significant step forward in assuring the quality of drinking water, it only provides a means of quickly and accurately iden tifying problems after they occur. It does little to prevent these problems from occurring in the first place. This is because much of the chemical test

ing conducted in order to optimize and monitor the treatment process (e.g., chlorine, turbidity, colour, fluoride, pH, etc.) is not performed in accredit ed laboratories. Generally, these process tests are governed under oper ator certification or through specific analyst certification. There is little or no direct oversight of the testing proce dures used, whether they are suited to purpose or whether they perform as designed. This is disconcerting given the fact that results from these tests are

used in day-to-day operational decisions. To illustrate the importance of proper controls at the process testing level, an analogy to loss control theory can be drawn. Most managers and supervisors are familiar with the ice berg or pyramid models of accidents. For every accident there is a large

number of near misses and an even

greater number of substandard condi tions that could lead to an accident.

The best means of reducing the num ber of accidents is to directly address these conditions. Following the same logic, the most effective way of reduc ing the number of adverse water quali ty conditions (or C of A exceedences) is to address substandard process con ditions, including the process testing. As has been demonstrated with ana

lytical laboratories, two ways to improve the accuracy and reliability of test results is to actively participate in a proficiency testing program and to be part of an operation that conforms to an applicable standard. The trend towards the management and opera tion of utilities to international stan

dards started prior to the Walkerton tragedy but has been accelerated in recent years. Ontario has enacted legis lation that will require drinking water utilities to become accredited to a spe cific standard (still to be defined). However, proficiency testing, a tool with a proven track record, has not yet been considered in the field of process

testing. In large part, this is due to the general belief that analytical testing and process testing are fundamentally different. This is a misconception. It is true that the average process test may not need the accuracy expected for analytical labs, but this does not justi fy a complete lack of control proce dures. At present, many utilities lack or have inadequate procedures in place to ensure that the process tests are per forming as designed. Sometimes, the first indication that there is a problem with the test is when the results

obtained for samples are observably different from those typically meas ured. By now, any problems with the testing procedure have been reflected in the entire treatment process. To conclude, the experience of the environmental laboratory industry in Canada clearly demonstrates that pro ficiency testing and accreditation to an international standard provide real and measurable benefits to laboratories

that undertake these strategies. Contact Ken Middlebrook, CAEAL,

Conference REPORT

ES&E's Canadian Environmental Conference

and Tradeshow attracts some 2,000 visitors There were over 40 presenters representing Canada's lead ing-edge environmental trainers, lawyers, consultants, managers, administrators, and health and safety practition ers.

Toronto Congress Centre

The 6th Annual Canadian Environmental Conference &

While seminars dealt with complex legal and technical problems, a presentation by Doug Petrie, of Wiilms & Shier Environmental Lawyers, was especially notable. His session combined wit with incisive legal knowledge as he took delegates through some of the complex environmental and legal labyrinths that industrial companies now face. Jim Bishop, an environmental chemist from Stantec, followed up with a masterly outline of the legal and techni cal issues of getting quality data from samples. He showed how faulty analyses could easily result from even slightly incorrect calibrations of laboratory equipment. These two presentations, from the differing viewpoints of law and chemistry, highlighted the fact that the legal implications of analyses are inescapably linked to expertise in both pro fessions.

Tradeshow (CANECT 2004) was held at the Toronto Congress Centre, May 12-13.

Some 2,000 industry professionals visited the 6th

Annual Canadian Environmental Conference &

Tradeshow (CANECT 2004), co-organized by Environmental Science & Engineering magazine (ES&E) and Canadian Environmental Regulation & Compliance News. CANECT 2004 was co-located with the annual Toronto Instrumentation, Systems and Automation (ISA)Tradeshow.

Since 1992, the organizers of CANECT have put on a highly successful annual conference on Environmental Management, Compliance & Engineering that has been the

foremost event for Canadian environmental managers, plant personnel, government policy-makers, lawyers and consultants with responsibilities for environmental affairs.

Jim Bishop (left), Stantec Consulting, gave a masterly review of the complexities of obtaining quality analytical data while John Wiilms (right), of Wiilms & Shier Environmental Lawyers, dealt with regulatory issues relating to industrial water and wastewater.

Other topics presented included:

• Environmental Regulation & Compliance • Dealing with Industrial Air Pollution • Environmental Management: Establishing a Costeffective EMS

• Dealing with Industrial Waste

• Environmental Health & Safety Due Diligence for Managers and Supervisors • Insider's Guide to Investigations and Inspections • Dealing with Industrial Water and Wastewater • Dealing with Industrial Contaminated Land

• Dealing with Spills and Environmental Emergencies Doug Petrie (left), of Wiilms & Shier Environmental Lawyers, and Adam Quipp (right) of RWDi gave presen tations at the session on dealing with industrial air emis sions. Mr. Petrie spoke on prosecution and enforcement issues. Mr. Quipp's presentation was on certificates of approval, air emissions - options and variables.

Environmental Management

How companies can get the most out of their



Many organizations have invested considerable

resources in the design and iinplementation of an Environmental Management System with out necessarily realizing the well-documented benefits. Organizations have been driven to portray a "green" image as a means to enter new markets, reduce attention from regulators and avoid damaging press. In reaction to external pressures, organizations have

implemented an EMS with the sole objective of complying with regulations, standards, protocols, etc. Management's focus often appears limited to compliance and satisfying auditors. Strategy and value become elusive when regula-

To realize the full potential of an EMS companies should focus on performance improvement instead of simply compliance.

tions and procedural standards, such as ISO 14001, take precedence. An organization should focus instead on per formance improvement as its strategic and value-creation goals are then more likely to fall into place. ISO 14001 is an auditable protocol. It is not a strategic management document and, therefore, should not be used as the starting point in the design of an EMS. The standard does not provide any guidance for directing performance improvement, developing performance indicators, improv ing processes or integrating corporate strategies. However, registration to ISO 14001 is still essential, as it provides the world independent assurance that an organization's EMS complies with an internationally accepted set of principles. Organizations can also comply with other supporting standards, such as the Global Reporting Initiative Guidelines and the Greenhouse Gas Protocol Initiative



(GHG Protocol), to provide verification of the accuracy

and relevance of published data and reports. Just as compa nies do not use GAAP (Generally Accepted Accounting Principles) to drive their management programs (although they strive to comply with its principles), environmental managers should not let environmental certification stan dards and guidelines drive their environmental manage ment and performance improvement strategies. Develop a strategic model The starting point in designing an EMS should be to develop a business case based on a strategic model designed to improve the organization's environmental per formance and bottom line. Unfortunately, the development of a strategic model is often overlooked, resulting in processes being driven by a checklist of required elements, extracted from a standard or obtained from a list of regula tions. Companies that have made the effort to develop a strategic model, such as IBM, Baxter, Dupont and British Telecom, have realized significant value creation, as well as public recognition. By stepping back and taking the time to design a strate gic model to guide corporate environmental management, organizations can create value. They do not have to reinvent the wheel, as there are many documented case studies, as well as guidelines published by a variety of respected organizations.

Environmental Management One example is the SIGMA Guidelines. These guidelines provide clear and practical advice, enabling organizations to make a meaningful contribution to sustainable develop ment. Another highly regarded strate gic-based guideline is The Natural Step, and an organization can easily strengthen the performance compo nent of its EMS by incorporating these principles into its strategic model. Such guidelines are not registration documents, although they link into existing management systems and

Many strategic initiatives can be simplified to a "performance-based EMS" that focuses on performance and integration. Upon completing a study of ISO 14001-registered compa nies, researchers at the University of California found that overall improve ment in environmental stewardship appeared to fall short of expectations. Researchers were unable to obtain the

quantitative information required to evaluate the benefits of ISO 14001.

The study appears to prove, once again, that "you cannot control what you do not measure". Create a process matrix The first step in designing a per formance-based EMS is for manage ment to develop a performance matrix that will guide the development of the EMS. When designing the perform ance matrix, management needs to cre ate a list of organizational objectives that are to be achieved or furthered

with the implementation of the EMS. For example, the organization may want to improve social impacts, reduce insurance costs and legal fees, elimi nate regulatory fines, improve access

should then be identified as a means of

measuring the progress in achieving the objectives. As many organizations are already performance-driven, this provides the simplest way of integrat ing the EMS with corporate-wide objectives and management processes. The EMS performance matrix should fit and feed into the overall cor

porate matrix. The detailed EMS measures provide information about the performance of the EMS and its value in achieving corporate objec tives. The EMS performance matrix will be incorporated into the facility's performance matrix, which will be consolidated at the corporate level. Such an undertaking should be coordinated at the corporate level as well. This will ensure that performance data can be consolidated to provide an accurate picture of overall perform ance, as well as a breakdown and com parison of performance by facility. Value creation then can be traced back

to individual measures, EMSs and facilities. This structure allows man

agement to drill down to the weakest link in its drive to improve perform ance.

Map performance to process The next step is process mapping, through which each performance indi cator is mapped across facility and cor porate processes. Mapping helps deter mine which processes will affect each facility's ability to achieve its objec tives - and how. This undertaking drives the development of procedures and controls needed to achieve each of

the EMS objectives.

In the mapping process, the prac tices of various departments are stud ied, controlled and integrated. For example, to track environment-related costs, the accounting department may need to integrate the principles of ecoaccounting. And to control inputs, the purchasing department may seek to embrace "green" purchasing. Conclusion

ISO 14001 registration provides assurance of an organization's compli

vide a framework to create value or

justify continued investment in sus tainable management. On the other hand, a performance-based EMS will help create value through performance tracking and integration. ISO 14001 can then be used to ensure that the pro cedures, controls, resources, responsi bilities, objectives, etc. are sufficiently documented and are being implement ed as documented.

Implementing an EMS element by element appears to create a complacent attitude within an organization. Highly-respected companies around the world have achieved significant value creation, improved environmen tal and social performance, and gained considerable respect by managing their EMSs under the guidance of a strategic model. Many of these organizations also obtained ISO 14001 registration at several of their facilities to demon

strate that their processes are docu mented and transparent, their public claims are accurate, and they are meet ing their commitments. Contact Green Ware Environmental

New technology demonstrated for landfill gas utilization system in Salvador,Brazil

In June 2003, under the auspices of the Sustainable Cities Initiative of the Government of Canada, with

funding from Technology for Early Action Measures (TEAM), a pilot-scale landfill gas (LEG) collection and utilization system was implemented at the Canabrava Landfill in the City of Salvador, in northeastern Brazil. The pilot-scale system was designed and assembled in Canada and shipped to Salvador, Brazil, as a skid-mounted system. The system includes a reciprocating engine from Waukesha and a WEG generator, within the steel contain er. The skid-mounted approach worked extremely well in terms of facilitating transfer of necessary equipment from Canada to Brazil, and as a security measure while it contin ues to operate at the Canabrava Landfill. The pilot-scale system of75 kW/h of electricity is being used to demonstrate how LEG can be utilized for beneficial

wastewater treatment company spe

cializing in chemical-free technology for municipal drinking water and medium to large industrial wastewater treatment. Its wastewater applications range from pulp and paper to pig waste to the food and beverage industries. For the past fifteen years, WWM's research and development department has focused on its Oxycair line, a multi-media technology treating municipal surface and ground water to ensure bottled-water quality in drink ing water. Now, based on these advanced principles, the Oxycair XPM technology has evolved to the point where the same water quality stan dards can be produced from sources as severe as landfill leachate.

As the process stream slows across the concentration chamber to a still zone at the opposite end from the intake, gases are released, the temperature decreases, and salts that are at, near or above saturation levels solidify and set tle to the bottom. Final settling of most solids occurs throughout the still zone within the chamber, preventing them from reentering the process stream. Following a pro duction cycle, the pressurized air cap is used to rapidly and completely empty the liquid, solid, and gaseous con tents of the concentration chamber through a blow down port.

strategies. Transportation alone, from the landfill site to a mill's wastewater

treatment plant, may cost $500,000 or more, depending on the distance from a landfill site to the secondary treat ment facility. Without the need for additional treatment facilities, a com pany will also save the chemical costs usually associated with the treatment of leachate.

Most important, third party results demonstrate that the XPM is meeting the most restrictive of government standards, allowing direct discharge into the environment at the demonstra tion site.

With rising energy costs, water reuse within a plant for washing, cleaning, sanitizing, boiler processes and cooling towers is of high priority and, with the XPM technology, can now be realized. The ability to close the loop within an industry eliminates additional water usage, saving compa nies the rising cost of water as well.

Storm Drainage

Curb inlets can improve service and reduce cost By A.R.Perks and R.G. Hewitt

Some Canadian municipalities

have been installing curb inlets for roadway storm drainage because they are easier on bicy clists and traffic, and less costly to install and maintain than traditional

grated inlets. The curb inlets make it easier for snow clearing as well - no more damaged snowplow blades and inlets in winter.

Curb inlets (also known as side opening inlets) are set into the face of

the curb rather than in the road gutter itself(see Figures 1 & 2). This means that there are no iron grates in the traf fic lane for cars and bicyclists to avoid.

(i.e. less than 0.5% - 1% slope), the gutter flow just by-passes the inlets. However, when installed at low


For the curb inlet project, the flume (model) was set up to represent the City's curb inlet design at a one-half scale, and a series of experiments was carried out under different flow and

roadway conditions, such as road/gut ter slope, cross fall (ie. side slope) and gutter shape to establish hydraulic capacity. The laboratory results clearly showed that under most practical road way conditions, the curb opening inlets have substantially less hydraulic capacity than the standard drop inlet gratings. The curb inlet "efficiency"is between 10% and 20% for most road-

points or sumps, the curb opening inlets act in a different way, as basic orifices or broad crested weirs. Then, their capacity increases under the hydraulic head available, and they behave comparably to the standard grate inlets. The resulting problem is that using typical inlet spacing derived for stan dard grated inlets, the street gutters will be forced to carry significantly more flow, and potential for flooding will exist at the next low spot in the road, for example. While the problem may not manifest itself for many years along a given street, eventually a storm

in developing the necessary informa tion, such as flow capture based on varying road and cross fall slopes, for designing the new inlets as part of the City's roadway design procedures. RVA had previously worked on the City's storm sewers and design criteria, and the University of Ottawa had pre viously done research into roadway drainage for the Ontario Ministry of the Environment, and still possessed the specially designed laboratory 624


In addition, the tests showed that

the addition of a depression in the curb at each inlet does not dramatically improve the efficiency ofthe flow cap ture rate.

The main factor is simply that the City of Ottawa curb inlets are less than

Other municipalities should also update their drainage design standards to allow for the design of curb inlets based on road slope, cross fall, gutter shape, spacing and lateral spread. In addition, municipalities might consider wider inlets, using upstream flaring and/or gutter depressions to maximize capture, and be especially cautious on steeply sloping streets where unintended ponding might occur at low points. Additionally, over land flow routes may need to be pro vided at these locations.

Golf courses swallow up lots of water The Canadian Bottled Water Association wants golf courses, farmers and municipalities to pay for taking water from Ontario's lakes and rivers.

Representing 56 companies who bottle water in Canada, 20 of them in Ontario, the association supports proposed provincial legislation that would charge companies that take water out of Ontario's watershed, but it wants all users to pay. "If such charges are imposed, we believe they should be fair and applied to all who use water," spokesman Larry Brookes said. Currently, companies such as water bottlers who take more than 50 cubic metres of water a day don't have to pay for it, as long as they have a permit. There are about 5,300 water-taking permits allowing companies to take about 160 billion litres of water a day. But that number is just an estimate because the gov ernment cannot track how much water is actually being taken. Proposed legislation aims to change all that. The first part, dealing with regulation should now be in place. The second and third parts of legislative proposals involving permits and levies, are to be introduced later this year. Ontario's 650 golf courses use 81 times more water than bot tlers, according to an Association spokesperson.

Ontario's Peel Region begins major expansion of infrastructure facilities Construction

of one

of Canada's

largest expansions of water and wastewater infrastructure has begun, announced Mark Schiller, Director of Water and Wastewater Treatment for

the Region of Peel, on June 29. The expansion projects total over $600 mil lion in capital expenditures and will support growth and development in Peel Region for the future. In 1999, Peel Region identified the need to expand the Lakeview Wastewater Treatment Facility, Lakeview Water Treatment Facility

and Caledon areas.

"We are upgrading the facilities with


of the



advanced treatment technologies", says Schiller. "These new technologies will generate positive benefits for local residents, such as higher water treat ment capacity, odour reduction and improved benefits to Lake Ontario." "Constructing three multi-million dollar facilities, at the same time, while maintaining service levels, is an ambitious business management initia tive," Schiller said, "but between our

Canadian Business magazine selects ZENON COO as top in operations Rafael Simon,ZENON's Chief Operating Officer, has been selected as one of the best managers in Canada and ranked number one in operations by Canadian Business magazine in its third armual list of outstanding executives. ZENON also ranked in the top 10 of the Top 60 All-Star companies in Canada with a three-year average annual growth in net sales of 30%, net income of 63% and total shareholder return of 37%, according to the maga zine's April 26th issue. The ranking was conducted by Bain & Co., Canadian Business magazine and a panel of industry experts who worked together to select the top executives in various categories. In 2003, the company was the recipient of the prestigious Stockholm Industry Water Award for its innovative approaches to the development of water and wastewater process technologies, along with its contributions to environmental improvement.


Water Treatment

Facility will expand daily treatment capacity to 820 million litres from 560 million litres. There is approximately $135 million budgeted for this project. When completed in 2006, the Lakeview Water Treatment Plant will

have the world's largest membrane fil tration operations. Maja Prentice, Chair of the Region's Public Works committee said, "The Region of Peel has been industri ous in saving for these expansions and we are committed to constructing the facilities on-time and on-budget." For all three facilities, the bulk of

the expansion work will be completed by 2006. The treatment processes involved with these new wastewater

facilities significantly reduce odour. 54 Environmental Science & Engineering,June/July 2004

The fee will cover the costs of collection, transportation and recycling of electronics material, education and awareness programs and electronics recycling relat ed research. Collection will be co-ordinated through locally run depots and drop-off points across the province. The e-recycling program is a key part of the Government of Alberta's strategy to reduce the annual per capita waste going to landfills from the cur rent level of 750 kilograms per person to 500 kilograms by 2010.

Ontario toughens operator training requirements A new regulation under the Safe Drinking Water Act, 2002, has been

62 Environmental Science & Engineering,June/July 2004

This tough new regulation will address eight of Commissioner O'Connor's 10 recommendations on

certification and training in the Report of the Walkerton Inquiry. The govern ment will work with the water industry to improve access to training across the province, which will address the remaining two recommendations on certification and training. Most aspects ofthe regulation come into force on August 1, 2004. The Ministry of the Environment will help ensure those affected by these new rules have the tools needed to help them meet the new standards quickly and effectively. The new training requirements come into force on August 1, 2005. Ontario water treatment facilities to be modernized The Ontario government will invest

over $400 million into safe drinking water, including money to allow more communities to upgrade and modern ize their water treatment facilities to

help them meet tough standards set out in the Safe Drinking Water Act. The funding was amiounced in the May 2004 Budget. The 2004 Ontario Budget also increases the operating budget for the Ministry of the Environment to $304 million, its highest level in a decade. About half of the MOE's operating budget is committed to providing safe drinkinu water.


The benefit of bedding material in a concrete pipe installation has been underestimated for far too long. Current OPS specifications do not reflect the recent research by the National Research Council ofCanada(NRC)on the real impact ofbedding. Data is now available from the three-year study that supports 20 years of research on the engineered value of Standard Installations. Recent recognition of Standard Installations by the Canadian Highway Bridge Design Code should ease the mind of any design engineer. It's the most direct route to project success. Standard Installations (Concrete Pipe Bedding Specifications) put the designer back in the driver's seat. Consider these benefits:

o Increased range ofbedding materials optimize native soil use o Specified compaction requirements ofvarious embedment material Measured relationship between bedding quality and pipe strength Accurate understanding ofthe benefit ofcurrent bedding practices Various bedding alternatives that economize design Improved site control Standard Installations are not about changing current bedding practices, but more about sound, efficient and accountable concrete pipe installations. Standard Installations also maintain the historical confidence that comes from using concrete pipe. To take a test drive and learn more about Standard Installations or to obtain your free copy ofPipePac design software, please contact the Ontario Concrete Pipe Association.
