2 Sewage Pumping Station (SPS) Definitions Sewage pumping stations are used for pumping sewage (i.e. wastewater) from a lower to higher elevation, particularly where the elevation of the source is not sufficient for gravity flow and/or when the use of gravity conveyance will result in excessive excavation and higher construction costs. The wastewater leaving the SPS is discharged through a forcemain to the next point in the sewage system. Forcemain A pipe that conveys wastewater under pressure from the discharge side of a pump to a point of gravity flow or another sewage pumping station. Gravity Sewer A pipe that uses a declining grade to cause wastewater to flow downstream. Service Area The geographic area which is serviced by a sewer network that discharges to a particular point.

3 Introduction The City of Peterborough has recognized the need to provide new residential areas, with this growth comes the need to upgrade existing infrastructure to ensure that all future growth can be serviced. All Municipalities are required to follow the planning process as outlined in the Municipal Engineers Association s (MEA) Municipal Class Environmental Assessment (EA) Document (as amended in 2007). The process presents the public an opportunity to provide input to ensure that all municipal projects consider not only economic and technical factors but social and environmental factors as well. The end result is a publicly supported and environmentally responsible project.

4 Class EA Process General Overview Agency/Public Consultation Notice of Commencement (Posted on the City Website, Peterborough This Week, Peterborough Examiner) PHASE 1 Identify & Describe the Problem or Opportunity The process can involve up to five phases depending on the Schedule chosen. PHASE 2 Evaluate Alternative Solutions & Establish the Preferred Solution Discretionary Review Agency/Public Consultation Public Open House (Posted on the City Website) Schedule A projects are considered to have minimal environmental impacts. Mandatory Review Agency/Public Notification of Project Completion (Currently Available for 30- Day Review) PHASE 3 Identify Alternative Design, Environmental Effects & Preferred Design PHASE 4 Prepare Environmental Study Report (ESR) Documenting Phases 1-3 File ESR Mandatory Review Agency/Public Consultation Discretionary Review Agency/Public Consultation Mandatory Review Agency/Public Notification Schedule A+ are considered to have minimal environmental impacts but require the proponent to advise the public of the work. Schedule B projects are considered to have some environmental impacts and therefore must proceed through Phase 1 and Phase 2. Opportunity for Part II Order Request (Formerly referred to as bump-up ) PHASE 5 Complete Drawings & Documents Proceed to Construct, Operate & Monitor Project Schedule C projects are considered to have considerable adverse environmental impacts and require all five phases be completed.

5 The scope of work for the upgrade of the Parkhill Road SPS triggers a Schedule B undertaking as it involves (as stated in the MEA document): Construction of a new pumping station or increasing pumping station capacity by adding or replacing equipment or appurtenances, where new equipment is located in a new building or structure. Schedule B projects require the completion of Phase 1 and Phase 2 of the EA Process. Phase 1 Identification of the problem. Phase 2 Inventory of the natural, social and economic environment; Identification of alternative solutions and impacts; Selection of a Preferred Solution, and; Development of alternative design concepts for the Preferred Solution. Class EA Process Schedule B

6 Problem Statement Phase 1 requires the proponent of an undertaking to first document factors leading to the conclusion that the improvement is needed and ultimately, to develop a clear statement of the identified problem to be investigated. As such, the Problem Statement is the principle starting point in the undertaking of a Class EA and becomes the central theme and integrating element of the project. It also assists in setting the scope of the project. The problem statement for the project is as follows: The City of Peterborough has identified the need to provide additional sewage pumping capacity to service the current and future development in the Jackson Creek and Lily Lake Planning Areas.

7 Jackson Creek Planning Area Sanitary Servicing GRAVITY SEWER TO THE PARKHILL ROAD SEWAGE PUMPING STATION Sanitary flows from area south of Parkhill Road conveyed via gravity sewer to existing Parkhill Road SPS via sanitary sewers in the Parkhill Road SPS catchment area. Sanitary flows from the area north of Parkhill Road conveyed via gravity sewer northeast, crossing Jackson Creek, then following the alignment of the Jackson Creek Kiwanis Trail (Approx. 700 m); crossing Jackson Creek and discharging to the existing Parkhill Road SPS. In order to service the development prior to the SPS upgrade, a temporary lift station will be constructed on the SPS property to accommodate this sewer. Exact alignment and infrastructure requirements will be designed by others.

8 Lily Lake Planning Area Servicing Alternatives

9 Evaluation Methodology and Criteria Evaluation criteria were developed based on the following environmental components that address the broad definition of the environment described in the EAA and used to evaluate alternative strategies. Natural Environment Social/Cultural Economic/Financial Legal/Jurisdictional Technical Component having regard for protecting the natural and physical components of the environment (i.e. air, land, water and biota) including the natural heritage-environmentally sensitive areas Component that evaluates potential affects on residents, neighbourhoods, businesses, community character, social cohesion, community features, and historical/archaeological and heritage components in addition to municipal development objectives. Component that compares the potential costs. Component that considers land requirements, permit requirements and the potential legal implications for each alternative. Component that considers technical suitability and other engineering aspects of the alternatives.

10 Evaluation Matrix Alternative 1 Do Nothing Alternative 2 Upgrade Parkhill Road SPS to service Jackson Creek and Lily Lake Planning Areas Alternative 3 Upgrade Parkhill Road SPS to service Jackson Creek Planning Area and Upgrade Valleyview SPS to service the Lily Lake Planning Area Alternative 4 Upgrade Parkhill Road SPS to service Jackson Creek Planning Area and upgrade sewer infrastructure downstream of Fairbairn Street to service Lily Lake Planning Area

11 Preliminary Preferred Alternative After evaluating all the alternatives the preferred alternative is to service the entire Jackson Creek and Lily Lake Planning Areas with the Parkhill Road SPS. This will result in the need to upgrade the Parkhill Road SPS to accommodate a design sewage flow of 406 L/s; Incorporates the preferred alternatives for both the Jackson Creek and Lily Lake Planning Areas; Existing SPS site provides adequate space with minimal impact to the public during construction, and; No upgrades are required at the Valleyview SPS or any sanitary sewer infrastructure downstream of Fairbairn Street.

12 Parkhill Road SPS Existing Conditions Plan

13 Proposed Parkhill Road SPS Site Plan Exact location and configuration of wet well and control building to be determined during detailed design.

14 Next Steps/Comments Once the Public has had a chance to review the information and provide feedback final review of the project will be completed and the Project File Report will be made available for viewing. The Public will have 30-days during which they can raise questions/concerns to a project team member or request a Part II Order from the MOE. If there are no outstanding issues and no Part II Order Requests the project will be considered approved and the City may proceed with the Preferred Alternative. The EA Process encourages public participation. If you have comments or would like more information about the project or the EA process please contact one of the project team members listed below.
