Crerar Sewage Lift Station Improvements
Crerar Boulevard Sewage Lift Station is located near the intersection of Crerar Boulevard and Lakeshore Boulevard, as shown on Figures 1.2. The pumping station receives sewage from fully developed residential areas to the north and from Kingston West Water Treatment Plant, and conveys it easterly for treatment at Kingston West Water Pollution Control Plant.
Crerar Boulevard Sewage Lift Station was constructed in the 1960's and was upgraded in the 1990's. The station is in need of further improvements, as described below.
Utilities Kingston has retained Totten Sims Hubicki Associates to provide engineering services for a condition assessment, class environmental assessment, detailed design and construction administration for Crerar Boulevard Sewage Lift Station improvements. The condition assessment and preliminary design work is now complete. The purpose of this mailing is to inform you of the recommended solution.
A condition assessment of Crerar Boulevard Sewage Lift Station has been completed and has observed the following:
- The theoretical sewage flow generated from the Crerar Boulevard Sewage Lift Station drainage area exceeds the station's firm capacity;
- The standby generator does not have adequate capacity to provide emergency power for both duty and standby pumps;
- The existing magnetic flowmeter does not have a recorder nor is it connected to the City's SCADA system;
- The diesel generator and transfer switch are old and indications are that the unit is not consistent in its ability to start every time it is called to run.
The purpose of this environmental assessment is to plan for an increase in the rated capacity of Crerar Boulevard Sewage Lift Station to meet current and future demands and to undertake the capacity improvement as part of an overall program to update the existing facilities.
Public and Agency Consultation
A Notice of Study Commencement was advertised in the Kingston Whig Standard and in Kingston This Week commencing on April 11, 2006. Copies of a brochure, similar to this one, were circulated to residents and businesses within 120 m of the Crerar Boulevard site. Copies were also forwarded to a long list of interested review agencies.
As a result of the above circulation one request to be added to the mailing list was received from a member of the public and four agencies responded in writing that they have no concerns/objections to the proposed improvement. Utilities' staff also responded to telephone callers requesting additional information.
Analysis of Alternative Solutions and Selection of recommmended Solution
An analysis of alternative solutions has been completed and is documented in a Phase 1 and 2 Report. Options including "Do Nothing" and "Build a New Facility at Same or New Location" have been evaluated. Renovation of the existing facility, with additional capacity to handle future flows, is the recommended solution.
The recommended solution can be further detailed as follows:
- Increase rated capacity from 51 L/s to 77 L/s to meet current and future needs. Increased capacity may be implemented in stages, as needs indicate, and may involve upgrades to existing pumps or new pumps.
- Upgrade standby generator capacity to satisfy new capacity requirements- replace the existing 24 kW unit with a 35 kW unit.
- Replace access hatches on existing 3 m diameter in ground wet well if required to accommodate larger pumps.
- Replace ventilation, electrical, flow monitoring and SCADA equipment that has reached the end of its useful life, as indicated in the Condition Assessment Report.
The recommended solution includes a listing of commitments that are summarized on the following table:
|Construction Impacts||City noise by-law will be enforced.|
|Standard specifications regarding no work in watercourses, refuelling areas remote from watercourses, and reporting of spills will be included in construction documents.|
|Construction will be completed as quickly as possible.|
|Management of Surplus Materials||Surplus materials generated by construction will be handled in accordance with Ontario Provincial Standard Specification 180.|
|Maintenance of Service||Capacity to pump sewage will be maintained at all times.|
|Noise||Noise suppression will be installed on new generator facilities. MOE Certificate of Approval (Air) will be required.|
|Maintenance of Sewage Collection System||Ongoing maintenance of sewage collections system will be required to ensure that the new pumping capacity is sufficient for all future needs.|
|Agency Approvals||Applications will be made for amendment of MOE Certificates of Approval to authorize changes to station rated capacity and for upgraded generator facility.|
Class EA Process
This project is being undertaken in accordance with procedures for a Schedule B project as set out in the Municipal Class Environmental Assessment, June 2000. Schedule "B" projects are those with modest impacts which are approved subject to a defined screening process.
The Class EA process provides for public and review agency input to allow all concerns to be identified and addressed when evaluating solutions. Notice of Completion of this EA has been issued through circulation of this brochure, and through newspaper advertisements. The project file, which consists of the Condition Assessment Report and a Phase 1 and 2 Environmental Assessment Report, is available for review. Comments on the Recommended Solution are invited. If concerns arise regarding the project which cannot be resolved in discussion with Utilities Kingston, a person may request that the Minister of the Environment make an order for the project to comply with Part II of the Environmental Assessment Act (referred to as a Part II Order), which addresses individual environmental assessments. If no concerns are received within 30 days of the issuance of the notice of study completion the project may proceed to construction.
