Information presented in this plan has been developed based on the document Guidelines for the Preparation of an Operation and Maintenance Plan for Sewage and Solid Waste Disposal Facilities (Municipal and Community Affairs, 1996). This document fulfils Part I of the Fort Providence Water Licence, Licence Number: MV2006L3-0002 which can be found in Appendix A. To assist personnel that operate the sewage lagoon and solid waste facility with proper operation and maintenance procedures, the following requirements are further addressed in this O&M plan: 1. Proper operation and maintenance procedures for the sewage and solid waste disposal facilities to provide effective treatment and operation; 2. Monitoring program description; 3. Appropriate methods and procedures for wastewater sampling; and 4. Data collection for annual reporting 1.2 Plan Organization This O&M plan was developed to instruct designated operators of the sewage lagoon facility and solid waste disposal site in Fort Providence on the operational and maintenance procedures required to comply with conditions set forth by the Mackenzie Valley Land and Water Board in water licence MV2006L3-0002. There is a section for the sewage lagoon (Section 3.0), and a separate section (Section 4.0) for the solid waste site. Each set of procedures is explained individually, with a summary of operational and maintenance procedures broken down into daily, weekly, monthly and annual tasks provided in Section 5.
