THAT Report PD-3-99 be received; 2. THAT Report PD-3-99 be approved as the comments of the Municipality of Clarington with respect to the Draft Environmental Study Report entitled 'Class Environmental Assessment for Additional Water Pollution Control Plant Capacity for Whitby, Oshawa and Clarington (Courtice)", as prepared by Totten Sims Hubiciki Associates for the Region of Durham; and 3. THAT a copy of Council's decision and this report be forwarded to the Region of Durham Public Works Department. 1. BACKGROUND 1.1 Durham Region commissioned the consulting firm Totten Sims Hubicki Associates to undertake a Class Environmental Assessment (EA) Report to address the water pollution control plant requirements needed to accommodate the planned growth identified in the Durham Region Official Plan for the Whitby-Oshawa-Courtice Urban Areas. Through the EA process, a number of alternatives are examined and a preferred alternative is identified. The 5 phases of the EA Report process are summarized in Attachment No.1 to this ~ort. '~'. 613 , , , , REPORT NO.: PD-3-99 PAGE 2 1.2 Staff previously reported to Committee on this study (Report PD-145-97, October 20, 1997). At that time, Phase 1 had been completed and Phase 2 had commenced. The Report endorsed by Council, provided the following comments: · the selection of a site in South Courtice was supported as this would provide for the servicing of Courtice's Employment Area lands; . the design of the Water Pollution Control Plant must be considerate of the existing recreational activities (Darlington Provincial Park) and the planned future recreational activities (District Park) in South Courtice. Design considerations should ensure sensitivity to the landscape, views and vistas, provision of a visual buffer from the parks, minimization of odour affecting the user's enjoyment of the parks or trail; . the new site should provide opportunities for the Waterfront Trail to be accommodated closer to the shoreline, and . the nine principles of waterfront development (clean, green, useable, diverse, open, accessible, connected, affordable and attractive) be taken into account when designing the plant; 1.3 Durham Region has recently submitted Phases 3 and 4 of the Study to the Municipality for comment. A portion of the Executive Summary has been attached for your information (Attachment #4). A copy of the complete draft report and appendices are available for review in the Clerks and Planning Departments. 1.4 The purpose of this Report is to present the findings of the Study for Committee's review and provide the Municipality's comments on the Phase 3 and 4 report. 614 , , REPORT NO.: PD-3-99 PAGE 3 2. PREFERRED ALTERNATIVE 2.1 The existing Harmony Creek Water Pollution Control Plant is nearing capacity, and additional capacity will be required by the year 2001. The EA Report indicates that the preferred alternative is to construct a new water treatment plant to handle 30 MIGD (million imperial gallons a day). 2.2 Four sites in South Courtice were reviewed as potential locations for a new Water Pollution Control Plan (Attachment #2). Of the four sites, Site 2 was selected as the preferred site. Briefly, some of the reasons supporting the selection of Site 2 are as follows: . Significant hydraulic advantages which promote gravitational flows, reducing the need for pumping; . There is a gradual consistent slope on the site which will facilitate construction and gravity flow through the plant; . The location of the outfall diffuser takes advantage of the distance from any water intake pipes and the location of the Darlington Nuclear Generating Station outlet which will promote diffusion of the discharge; . The site can support expansion to 60 MIGD if necessary; . The site is at a sufficient distance from the Darlington Provincial Park to minimize any impact on the park users; . The site will allow the Waterfront Trail to be located in direct proximity to the lake Ontario shoreline; and . The financial obligations are the same or less than the other 3 sites. 2.3 The preferred site is located on Part lots 25, 26, 27 and 28 in the Broken Front Concession in the former Township of Darlington. This site is approximately 73 hectares in size and comprises 5 different properties (Attachment #3). The estimated cost of establishing a new plant on these lands is $157,000,000. 615 . , REPORT NO.: PD-3-99 3. 3.1 3.2 3.3 PAGE 4 i , i ISSUES DISCUSSED IN THE EA I The following is a brief description of the issuesli~pacts identified with establishing i the water treatment plant at the preferred locati01. The required separation distance is 150 metres between sensitive adjacent uses ~rimary impact zone). The report states that it has identified a secondary impact ~one of 150 metres to 400 metres (Attachment #3). It is acknowledged that within Ithis secondary impact zone, some impacts may be occasionally experienced. Environmental Assessment I An environmental report was conducted to d~termine whether any significant I wildlife or vegetative features are located withinl the limits of the site. The report I confirmed that the site does not support a wetlard or ANSI. However, out of the , four sites reviewed in South Courtice, Site 2 has fhe most vegetation and possesses I the best north-south wildlife corridors. In additif:>n, the existing east-west corridor , I located along the railway is enhanced through! the location of a small woodlot adjacent to the railway (Attachment #5). The rep rt states that the siting of the plant will be predominantly on agriculturally croppe fields and that there will be no impact other than removal of a portion of a nort -south treed fencerow which will be replenished by replantings. The report also st tes that there will be no long-term negative impact to wildlife resources. Agricultural Assessment The chosen site has been under agricultural culti ation for some time. The soils are identified as Class 1, being the best soils for a~ricultural production. The report notes that the subject lands account for less thfn 1 % of all farmland within the Municipality. However, the report does acknowl~dge that removal of this farmland , form each individual farm may reduce the viabili . of said farms. I 6116 I , , REPORT NO.: PD-3-99 PAGE 5 3.4 Economic Assessment The report states that Site 2 is large enough to accommodate any future increases in the population targets contained within the Official Plan. It will also provide sanitary sewer servicing in South Courtice, thereby facilitating the development of the existing unserviced industrial and residential lands within Courtice. Preparation and construction of the plant is expected to take approximately 30 months and up to 70 people will be directly employed on site during the construction of the plant. Approximately 40 new permanent positions will be required to operate the new facility. 3.5 Social Assessment The construction of the plant in this location will result in the relocation of one residence located within the 150 metre primary impact zone and the potential for 5 property owners to lose a portion of their properties. 3.6 Noise Assessment The noise report identifies Site 2 as the least preferred site from a noise perspective in that this location has the lowest level of background noise. 3.7 Odour Assessment Odour modelling was conducted for all four sites. The report states that the odour concentration is usually less than 10ou/m3 over 90% of the time. However, the maximum predicted odour concentrations at all four sites are well in excess of the 10ou/m3 value and some form of odour control must be included as part of the plant design regardless of the site selected. There was no variation between the four sites with respect to odour impact. 617 REPORT NO.: PD-3-99 PAGE 6 3.8 Visual Impacts The report briefly discusses that visibility is an issue and appropriate buffering will be provided. The report states that mitigation will be required. 3.9 Traffic Impacts When the plant's capacity is at 30MIGD, the report estimates that 137 truck movements will be generated a week (27.4 movements per day). 3.10 Impacts on Recreational Activities The report concentrates on identifying the impacts on Darlington Provincial Park and mitigation of those impacts. Darlington Provincial Park is located well beyond the secondary impact zone of 400 metres. The future alignment for the waterfront trail is located within the primary impact zone and portions of the future district , park may be located within the primary impact zone. Other portions of the park will likely be located within the secondary impact zone. However, very little analysis or even discussion is provided with respect to the waterfront trail and the future district park. This issue is further discussed in Section 4 of this report. 3.11 Interconnected Pipeline The project also includes an interconnected pipeline to divert sanitary sewage from the Harmony Creek Water Pollution Control Plant located in Oshawa, to the new Courtice Plant. Two 900mm diameter pressure sewers will be constructed between the Harmony Creek Pumping Station and the new Courtice Plant. Attachment #6 identifies the selected alignment of the pipeline. 4. STAFF COMMENTS 4.1 The lands identified as Site 2 (Attachment #2) are designated Waterfront Greenway within the Clarington Official Plan. The Official Plan also identifies a future District Park to be located within the vicinity of this site. The Official Plan recognized the 618 . . REPORT NO.: PD-3-99 PAGE 7 potential for a water pollution control plant to be located in South Courtice. If Site 2 is accepted as the location of the plant, an official plan amendment is not required. However, for the purpose of clarity, a future review of the Official Plan would incorporate an amendment to reflect the approved location. The lands are zoned Agricultural (A), Environmental Protection (EP), and Holding- General Industrial ((H)M2), within the Comprehensive Zoning By-law 84-63. The "Environmental Protection" zone is a 305m (1000 foot) buffer area along the lake Ontario Shoreline. 4.2 Waterfront Trail The development of the water pollution control plant will provide the Municipality and the Waterfront Regeneration Trust with the opportunity to fulfil their desire to have the trail located adjacent to the waterfront. The Region has indicated that it will make the lands along the shoreline available to the Municipality for the construction ofthe trail and related facilities. The mapping contained within the EA Report shows a trail corridor located inland to the waterfront from Courtice Road to the Darlington Nuclear Generating Station. The detailed alignment for the trail will be determined once lands are conveyed to the Municipality. The Municipality will need to continue to secure the alignment of the trail abutting the waterfront from the Darlington Provincial Park to Courtice Road, west of the subject site. 4.3 The report does little to address potential impacts to users of the trail. A portion of the trail is located within the 150 metre primary impact zone. The Draft Report should be revised to give consideration to visual, noise and odour impacts on the trail and it's users. More emphasis should be placed on providing mitigation techniques to bufferthe trail from this use. 619 REPORT NO.: PD-3-99 PAGE 8 4.4 Municipal District Park A municipal district park has been identified within the Clarington Official Plan and would be located in the vicinity of the water pollution control plant. The potential boundaries of the future district park are shown on Attachment #3. Although this site has not been confirmed, it will be affected by both the primary and secondary impact zone. The EA Report does not sufficiently address this potential land use in their review of impacts, nor in the discussion regarding mitigation. Examination of potential noise, odour and visual impacts on the future district park and its users should have been identified and addressed in more detail. 4.5 The visual impacts of the plant were addressed on a general basis. More information should be provided in the draft report regarding location of the buffer areas and planting strips. The report notes that the plant will be visible from lake Ontario. Given the previous impacts of the Blue Circle and Ontario Hydro on the Clarington waterfront, staff believe that this impact should be mitigated as much as possible. 4.6 The environmental component of this process dealt primarily with identification of wildlife corridors. A brief vegetation inventory was completed, however no wildlife inventory was prepared. 4.7 The site design stage will be important in resolving many of the above issues. The Municipality requests the opportunity to be fully consulted in the site design stage. 5. CONCLUSION 5.1 The selection of Site 2 as the preferred location for the new Courtice Water Pollution Control Plant is supported. The preliminary site design is shown in Attachment #7 to this report. 620 REPORT NO.: PD-3-99 PAGE 9 5.2 The Draft EA Report needs to be revised to address the impacts of the plant on the operation of the future district park and the waterfront trail. In addition, the section discussing the mitigation methods should be amended to include mitigation of impacts on the waterfront trail and municipal district park. 5.3 Staff request that the Municipality be consulted during the detailed design and siting of the plant. This will allow Staff the opportunity to ensure that the impacts on the district park and waterfront trail are properly mitigated.

Regional Municipality of Durham Class Environmental Assessment for Additional Water Pollution Control Plant Capacity for Whitby. Oshawa and Clarington (Courtice) Environmental Study Report (Draft) xx. Water Pollution Control Plant A new 68,180 m'ld (15 MIGD) water pollution control plant will be constructed in South Courtice over a twenty year period, in two separate phases. Each phase will have a capacity of 34,080 m'ld (7.5 MIGD). The timing of the second phase will depend upon the remaining service life of the trickling filter plant at Harmony Creek. The new plant will employ the conventional activated sludge process and include preliminary treatment, primary clarification, aeration, secondary clarification, anaerobic digestion and six (6) months biosolids storage. Effluent disinfection will be provided via ultraviolet (UV) irradiation. An environmental evaluation was conducted based upon the selected conceptual plant design and phasing, as well as the routing of required pipeline infrastructure. The analysis indicates that construction of a water pollution control plant on Site No. I would have the highest environmental impact of the four sites considered. The primary impacts include potential construction impacts upon Darlington Provincial Park and the negative perception associated with locating a water pollution control plant adjacent to the park. In addition, one residence would be displaced as a result of plant construction on Site No. I. The potential impact upon the park must be weighed against the potential loss of industrial or prestige employment lands associated with the development of Sites 3 and 4. The Municipality of Clarington has expressed concern with this potential loss, and the associated lost opportunity, should a new plant facility be constructed on either of these two sites. Both Sites 3 and 4 have Highway 401 access. The Municipality of Clarington has indicated that such prime industrial sites are in short supply within the community. Site Nos. 2 and 4 have the least environmental impact of the sites considered. Both sites provide approximately equal site area for plant construction and therefore comparable flexibility to accommodate future changes to the ROP and lor service area boundaries. The primary drawbacks associated with a plant at Site No. 4 are the need for a relatively large raw sewage pumping station to service proposed developments north of Highway 401 and west of Tooley Creek, as well as the need for an inlet pumping station at the plant due to the relatively high ground elevation at the site (average 150 metres). The inlet sewer to a plant at Site No.4 would be approximately 10 metres (33 feet) deep. In contrast to Site No.4, Site No.2 can accept flows from Courtice and northern Oshawa by gravity. A relatively shallow inlet pumping station would be required initially and the inlet sewer would be surcharged south of Highway 401 as plant flows increase. Site No. 2 offers some significant advantages from a hydraulic design viewpoint. In addition, constructing the new plant at Site No.2 provides the Region of Durham with an opportunity to relocate a portion of the Waterfront Trail closer to the Lake Ontario shoreline and incorporate the development of the proposed district park into the final plant design, both of which are positive benefits to the community. totten sims hubicki associates OLS Regional Municipality of Durham Class Environmental Assessment for Additional Water Pollution Control Plant Capacity for Whitby, Oshawa and Clarington (Courtice) Environmental Study Report (Draft) xxi. Given the operational constraints associated with Site No.4, and the opportUnities afforded plant construction on Site No.2, the preliminary preferred site. subject to public input, is Site No.2. Site No.2 is located south of the CN Rail line, east of Courtice Road and west of Darlington Provincial Park. The proposed conceptual plant layout is presented as Figure ES.3. Emuent OutraII An 1,500 mm (60 inch) diameter effluent outfall will be constructed approximately 1,100 metres (3,609 feet) offshore of Lake Ontario. The new outfall will have a diffuser section which is approximately 180 metres (590 feet) in length. The new effluent outfall will be terminated at a water depth of approximately 6 metres (20 feet). Provision will be made in the design to allow the outfall to be extended in future. if required. Wastewater Flow Reduction Strategies The Region of Durham will continue to implement and improve both their water efficiency and sewer rehabilitation programmes. These programmes will be maintained to reduce future wastewater flows and therefore reduce future infrastrucrure expenditures as well as associated operating costs. ES.5 PRINCIPAL CONCERNS AND MITIGATING MEASURES Several principal concerns were raised by the public and review agencies during the Class Environmental Assessment process. A summary of these concerns, as well as the proposed mitigation to address them, is summarized below. Drinking Water Quality Durham Operations staff raised concerns regarding the potential impact of a new or expanded Water PolIution Control Plant on area drinking water treatment plant intakes. A computer modelling study was carried out to determine the anticipated impact upon area water plants for construction of a Harmony Creek WPCP expansion or new plant in South Courtice. All simulations were conducted based upon a "worst case n peak flow of 440,640 m'/d (97 MIGD) and an assumed ultimate water pollution control plant capacity of 272,600 m'/d (60 MIGD). This capacity was calculated based upon the overall size of the catchment. This approach was taken to ensure the selected plant location is acceptable from a water quality perspective far into the future regardless of any future increases in ROP "population targets n and therefore plant flows. The proposed mitigating strategy includes locating the new effluent outfall as close as practically possible to the heated water discharge from the Darlington Generating Station. The heated water discharge at the Darlington NGS provides significant effluent dilution. In addition, the effluent outfall will be constructed to a depth of 6 m (20 feet) initially with provision to extend the outfall pipe in future, if required. . tonen sims hubicki associates / OLO J / ~ ,"IWS ~ I m I .; r'\ 1 H 'I 1 !, ~ , I ) I is ., II 1 ~< ~ I 0 ~, I ~el , ~ I i,1 , /1 7 ~ M I l 1 ~! ~i! ! 1 ) / ~! ~~l I \I ~ il"I' o ~.

Oshawa and Clarington (Courtice) Environmental Study Report (Draft) xxiii. Darlington Provincial Park A great deal of concern was raised with regard to the potential construction and operating impacts upon users of nearby Darlington Provincial Park. The following mitigating strategies are proposed : i) locate the new water pollution control plant at Site No. 2 well away from the park property . ii) locate the new effluent outfall as close as practically possible to the heated water discharge from the Darlington Nuclear Generating Station. The heated water discharge at the Darlington NGS provides significant effluent dilution and acts to push the treated effluent further offshore. iii) construct the proposed interconnecting pipeline through the park during the park off season between November 15 and May 15. iv) incorporate odour control measures into the new plant design, as required. v) provide significant vegetative buffer along the north, west and south side of the plant property. Darlington Nuclear Generating Station Water Intake Ontario Hydro has expressed concern with the potential impact upon the cooling water intake for the Darlington Nuclear Generating Station. The new effluent outfall will be located as close as practically possible to the heated water discharge which will push the treated effluent further offshore away from the intake. Computer modelling studies indicate that the outfall locations considered for this study will have little or no impact upon the Darlington NGS cooling water discharge. The relative impact for an outfall offshore of Courtice decreases with increasing water depth and provision will be made in the design to allow the outfall to be extended into deeper water in future, if required. Creek Crossings for Sanitary Forcemain The proposed undertaking will require pipeline crossings of Harmony, Robinson and Tooley Creeks. MNR, CLOCA and Friends of the Second Marsh have expressed concern with the impact of the crossings upon fisheries and adjacent riparian habitats. The following mitigating measures are proposed: i) All creek crossings will be done between July 15 and November 15. The crossing of Robinson Creek, within Darlington Provincial Park, will be done between October 15 and November 15 to coincide with the park off season. ii) All crossings will be done in the dry. totten sims hubicki associates bL8 Regional Municipality of Dumam Class Environmental Asscnment for Additional Water PoUution Control Plant Capacity for Whitby. Oshawa and Clarington (Courtice) Environmental Study Report (Draft) xxiv. iii) All crossings will be done as quickly as possible. iv) Only half of the watercourse will be isolated at anyone time when undertaking the crossings. Isolation will be accomplished with a simple cofferdam of sandbags, an Aquadam'" or sheet piling (Harmony Creek crossing). v) Bottom substrate will immediately be replaced and banks stabilized and revegetated once the crossing is complete. vi) An Environmental Inspector will be present throughout each crossing operation. vii) At each crossing site, an area wiII be temporarily set aside to isolate sediments and temporarily hold water for sediment removal from the dewatering process. viii) Silt fences will be erected along all watercourses prior to any work being completed adjacent to the watercourse. ix) Unless sod is used, erosion control matting is to be placed on all disturbed areas adjacent to watercourse crossings and remain in place until a cover crop has been established. x) After installation of mains. suitable river run substrate will be added to crossings areas to enhance fish habitat. Wildlife Linkage; A number concerns were expressed with potential impacts of a new plant upon existing wildlife corridors in the South Courtice area. A number of mitigating measures will be incorporated into the design and construction of the new plant to mitigate these impacts. These will include the following: . the majority of the construction will be confined to the existing cultivated areas to the west of the proposed plant site. . disruption to existing treed areas associated with road constrUction will be minimized. . the existing vegetative buffer to the north of the site (south side of CN Rail line) will be enhanced . . the vegetative buffer on the south side of the site near Lake Ontario will be enhanced. . the proposed pipeline south of the CN Rail line will be constructed south of the existing utility corridor which is the highest quality vegetated east-west linkage in the area. . sufficient land will be acquired with the sewer easement to permit the expansion of the existing wildlife corridor paralleling the CNR line. totten sims hubicki associates bL9 Regional Municipality of Durham Class Environmental Assessment for Additional Water Pollution Control Plant Capacity for Whitby. Oshawa and Clarington (Courtice) Environmental Study Report (Draft) xxv. Waterfront Trail The Waterfront Regeneration Trust asked that consideration be given to relocating the Waterfront Trail to the lakeshore as part of the plant design. They also requested that public parking be provided. The Region recognizes that a strip of land will be required along the south side of the plant site for a buffer and erosion setback. Part of this allotment could be used for a Waterfront Trail and/or a District Park. This site design feature represents a significant enhancement to the South Courtice area. ES.6 PROJECT FINANCING The estimated cost of the proposed undertaking is summarized in Table ES.2. TABLE ES.2 ESTIMATED COST OF PROPOSED PROJECT Item Stage I a Stage I b Stage2 .

If objections are received with the review period which cannot be resolved, the objector can request the Minister of the Environment to elevate the project to an Individual Environmental Assessment statUs, which is termed a "bump-up". It is the Minister's responsibility to decide if the objection is justified within a period of 45 days from notification of the request. ES.8 PROPOSED PROCEDURE Although it is not intended to have formal Public Information Centres during Phase 4 of the Class EA process, public involvement will still be encouraged. There have been issues raised during the planning process which can be addressed more fully at the detailed design and construction stage and it is expected that members of the public may become involved in those specific activities which hold their interest. totten sims hubicki associates 0)1 I i ~ D-- ',~..
