Description:
This project has been in development since 2002—though the EA was just approved in early 2010. The earth pressure balance TBMs, which avoid requirements for dewatering and impacting the aquifers, and the segmental precast concrete tunnel lining have both been procured. In 2009, Pickering’s city council initiated legal proceedings against York Region regarding the proposed twinning of York Regions sewage collection pipe, which carries sewage to the Pickering plant for treatment. The issue started when York Region planned to build an odour control facility in Pickering. In response, Pickering residents began a community organization called Stop the Stink in order to ensure that this facility did not get built. However, after York and Durham Region received EA approval from the Ministry of the Environment, the City of Pickering opted to try and settle the matter with York Region out of court. In the end, Pickering gained $10.3-million in road improvements and waterfront trail expansion. In addition, York Region agreed to fund an engineer for the City of Pickering to oversee the project at a cost of $377,000.The lawsuit was officially cleared in August 2010. In August 2011, York Region announced that construction will begin shortly. Construction was originally scheduled to start in early 2011, with completion scheduled for 2014.
