In 2013, the City of Greater Sudbury (City) completed a Schedule ‘C’ Municipal Class Environmental Assessment (Class EA) for the Lively/ Walden Wastewater System, to determine a long term solution to address capacity issues at the Lively Wastewater Treatment Plant (WWTP), limited additional capacity in the Lively wastewater collection system and gravity trunk sewer, as well as aging infrastructure throughout the system. Through the Class EA study, the following recommendations were identified to be carried forward to Detailed Design:
• Upgrade the wastewater collection system, including the Jacob Lift Station and gravity
• Decommission the Lively WWTP and Anderson Lift Station; and
• Upgrade and expand the extended aeration process at the Walden WWTP.
Following the filing of the Environmental Study Report (ESR) in October 2013, the City retained R.V. Anderson Associates Limited to complete the Detailed Design and undertake an evaluation of the existing and proposed gravity trunk sewer alignments and construction methods to limit impacts on adjacent properties and buildings. Through the evaluation, it was determined that replacing part of the existing infrastructure in its current location would create major disturbance for property owners, lead to possible demolition of structures and extend the project schedule in order to resolve property issues.
In consideration of the anticipated impacts, the City has requested R.V. Anderson Associates to review alternative alignments for sections of the proposed wastewater gravity trunk main. As the requirements for property acquisition, installation of infrastructure outside of the municipal right-of-way and crossing of waterways was not evaluated in the Class EA process, an addendum to the ESR is required.
Planning and approval for this project are proceeding under the Municipal Class Environmental Assessment (October 2000, as amended in 2007, 2011 & 2015), an approved planning document that describes the process that a municipality must follow in order to meet the requirements of the Environmental Assessment Act.
The Class EA process allows for the comprehensive evaluation of the environmental impacts of a project and the methods of completing that project, as well as an opportunity to solicit and consider public input.
As an Addendum to a Schedule ‘C’ Class EA project, public consultation with stakeholders is required. The public will be notified of the date and location of the Addendum once complete, through a similar newspaper and public notice. A Public Consultation Session (PCS) is also scheduled for September 12, 2019 to allow the Public to review and comment on the project file and be advertised at a later dated. Persons or parties wishing to provide input to the planning process for this project, or who require further information are invited to contact the individuals below.
