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.

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

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.
