THAT the Report EGD-008-10 be received; 2. THAT Council endorse the recommendations within Report EGD-008-10; and 3.

Respectfully by, Su fitted by: A.S. annella Reviewed by: Franklin Wu Director of Engineering Services Chief Administrative Officer ASC/jo February 16, 2010 CORPORATION OF THE MUNICIPALITY OF CLARINGTON 40 TEMPERANCE STREET, BOWMANVILLE, ONTARIO L1C 3A6 T 905-623-3379 F 905-623-9282 Report#EGD-008-10 Page 2 1.0 BACKGROUND AND PURPOSE 1.1 The Region of Durham, through its consultant, GENIVAR, is in the process of conducting the Courtice Trunk Sanitary Sewer Class Environmental Assessment (EA) to determine the preferred alignment to convey sewage flows from Whitby (Brooklin), north Oshawa, Courtice and west Bowmanville to the Courtice Water Pollution Control Plant (WPCP). Six preliminary alignments were presented at a Public Information Centre (PIC) on June 23, 2009. These alignments will be refined based on input from the public and stakeholder agencies and a comparative assessment of the six alternatives will be organized in an evaluation matrix in order to objectively assess the impacts and determine the preferred alternative. This evaluation matrix will be presented at a second Public Information Centre. On October 8, 2009, a meeting to discuss feedback gained from the June 23 PIC was held in the Municipality of Clarington Office. Attendees included representatives from the Region of Durham, Genivar, the Municipality of Clarington, and the City of Oshawa. Clarington has a vested interest in assuring that an alignment amenable to the Municipality's future development objectives is chosen from the preferred alternatives. To this end, accommodation of expanded future flow in Courtice, in the most cost-effective and efficient manner, is of the utmost importance. Clarington representative, David Crome, addressed this concern at a meeting with Region of Durham and GENIVAR staff on October 8`h, 2009, stating that evaluation criteria for the evaluation matrix discussed above should consider the need to fulfill Provincial targets and legislation, maximize economic development potential and implement the objectives of both the Region's and Clarington's Official Plans. GENIVAR representative, John Himanen, expressed GENIVAR's position in this matter, stating that while meeting provincial targets and legislation may not have been stated explicitly, it was clearly implicit in the evaluation criteria. Report #EGD-008-10 Page 3 2.0 ANALYSIS 2.1 Currently, the Municipality's ability to ensure that all municipal interests are being considered within the EA is limited despite statements issued by the Region of Durham in the Terms of Reference for the consulting assignment for with the EA study, which indicate that these interests will be considered in an appropriate fashion. The consulting assignment Terms of Reference indicate that an objective of the EA is to clarify the extent of the areas to be serviced by the Courtice TSS in various communities including Courtice. The Terms of Reference also states that the Courtice TSS has the potential to service some of the urban areas of central Courtice and also go on to discuss a potential alignment along Townline Road that would essentially eliminate the need for the Nash Road Pumping Station, noting that an alignment such as this would also potentially accommodate the majority of the existing developed areas in central Courtice that are currently serviced by the Farewell Creek Trunk Sanitary Sewer. This, in turn, would eliminate the need to pump these flows to the Courtice WPCP via the Harmony Creek Sanitary Pumping Station in favour of a simpler, more direct, gravity-fed route via the Courtice TSS. Attachment 1 provides the Sanitary Sewer Tributary Boundaries for both the Harmony Creek WPCP and the Courtice WPCP which Region staff have stated are not up for discussion, contrary to the Terms of Reference. Clarington is currently in the process of determining the level of intensification and green-field development that will occur in Courtice through the completion of the Courtice Main Street Study and the Growth Management Study associated with the Official Plan Update. As such, there is some concern that additional wastewater generated from future intensification may eventually surpass the existing capacity of the Farewell Creek TSS. To accommodate these potential future flows, the Farewell Creek TSS may need to be improved at considerable expense. The alternative proposed above, where existing flows from Courtice are diverted to the Courtice TSS, would provide a second, potentially more cost Report #EGD-008-10 Page 4 effective solution to the future capacity issues that may occur in the Farewell Creek TSS. 3.0 CONCLUSION 3.1 Given the above, at this point in the environmental assessment process the best option for ensuring that an optimal alignment of the Courtice TSS is chosen for residents of Clarington is to address the evaluation criteria that will be employed in the preferred alignment evaluation matrix. To enable staff to pursue Municipal interests in this matter it is recommended that Council endorse that Clarington prefers alternative alignments for the Courtice Trunk Sanitary Sewer that are environmentally responsible and sustainable and also provide options to address potential future servicing challenges in the planned Courtice urban area in a cost effective manner. This will support staff in advocating for the inclusion of an appropriately weighted evaluation criteria within the evaluation matrix that is consistent with Provincial growth targets and legislation, maximum economic development potential and the implementation of the objectives of both the Region's and Clarington's Official Plans.
