1 MISSISSIPPI MILLS WASTEWATER TREATMENT FACILITY 2012 ANNUAL REPORT Prepared by Deborah Turner Process & Compliance Technician Ottawa Valley Hub

2 Mississippi Mills Wastewater Treatment Plant Annual Report 2012 Please find below the 2012 Annual Performance Report and other supporting documents for the Mississippi Mills Wastewater Treatment Plant. This report is a requirement of the Environmental Compliance Approval (ECA) (formerly known as the certificate of approval (CofA)) Number DXR5U (issued February 16, 2011). The ECA allotted of the operation of both the lagoon treatment facility as well as the new wastewater treatment plant (WWTP). The new WWTP was brought into service on July 11, This report includes both the lagoon treatment as well as the treatment of the new WWTP. The Consulting Engineer s have listed the Substantial Completion date as July 25, The ECA provides for six (6) month window before new, more stringent, limits and objectives come into effect. Summary: Flow Exceedances: Two Raw Sewage Flow Exceedances to Lagoon: March 13 & 16. Three Lagoon Effluent Flow Exceedances: March 19, 20 & 21. Overflow Events: Two Overflow Events: March 16 and September Spills: Three raw sewage spills: two in February by the on-site contractor and one in September due to heavy rainfall.

The new WWTP ECA approves: A design average daily treatment capacity of 4,700 m 3 /d and a peak treatment capacity of 14,100 m 3 /d. Mississippi Mills Lagoon and WWTP Systems 2012 Annual Report

3 Average Day Flow: The ECA limits the annual average day volume of wastewater pumped from the Gemmill s Bay pumping station to the lagoon to 3,020 m 3 /d. In 2012, the annual average day flow was 2380 m 3 /d - this is/was 78.8 % of the lagoon system capacity. When flows are examined monthly, it is revealed that the 3020 m 3 /d limit was exceeded in March only. The limit of the new WWTP is 4700 m 3 /d. With an annual average day flow of 2380 m 3 /d, the new WWTP is at 35.9 % capacity. The chart below depicts the month average day flow from the Gemmill s Bay Pumping Station. Month Average Daily Flow WWT Influent (m3/d) Average Day Flow ECA Limit Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 2012 Peak Day Flow: The ECA limits the volume of wastewater pumped from the Gemmill s Bay pumping station to the lagoon to 9,900 m 3 on any one day. There were two (2) exceedances of this requirement in 2012: these days occurred on March 13 and March 16. The limit for the new WWTP is 14,100 m 3 /d. This limit has not been exceeded. Please refer to the attached Data Exceeded Compliance Range report for a list of dates when peak flow was exceeded and the corresponding volumes.

No effluent discharge from the sewage works shall be allowed between June 1 and August 31. There were three (3) days where effluent flow limits exceeded 5,500 m 3 /d. These days occurred in March. The May effluent flow limit of 17,300 m3/d was not exceeded. There was no lagoon effluent discharge after May 31, Please refer to the attached Data Exceeded Compliance Range report for a list of dates when the lagoon effluent flow was exceeded and the corresponding volumes.

(b) A description of any operating problems encountered and corrective actions taken On September 08, 2012, the Almonte area received an unusual amount of heavy rainfall in a very short period of time. As a result there was a small raw sewage spill at the WWTP. The spill was because the plant is designed to divert a portion of influent flow to an existing lagoon cell (attenuation pond) in the event of high influent flows. Unfortunately, this portion of the new plant had not yet been commissioned and a pipe plug remained within the pipe leading from the manhole to the lagoon. As a result, the manhole overflowed. OCWA staff members, with agreement from the consulting engineers, removed the pipe plug. Removing the plug should prevent a re-occurrence of this type of manhole overflow spill. Higher than normal effluent total phosphorus results were recorded in the fall of This has been attributed to the attenuation pond and how the operators had been returning its contents back to the plant. Operators have now learned the flow limits of this process. March 19, 2012 a laboratory error failed to provide a requested ammonia test result. The laboratory is reviewing their procedures.

Quality Control & Compliance with Provincial Regulations OCWA uses internal compliance auditing techniques by teams from within the organization but not from within the facility work team. OCWA operates the Mississippi Mills Wastewater Treatment Plant in accordance with provincial regulations. Here is how we do it: Use of Accredited Labs. Analytical tests to monitor your water quality are conducted by a laboratory audited by the Canadian Association for Environmental Analytical Laboratories (CAEAL) and accredited by the Standards Council of Canada (SCC). Accreditation ensures that the laboratory has acceptable laboratory protocols and test methods in place. It also requires the laboratory to provide evidence and assurances of the proficiency of the analyst(s) performing the test methods. Operation by Licensed Operators. The wastewater treatment plant is operated and maintained by the Ontario Clean Water Agency s competent and licensed staff. The mandatory licensing program for operators of drinking water facilities is regulated under the Ontario Water Resources Act (OWRA) Regulation 129/04. Licensing means that an individual meets the education and experience requirements and has successfully passed the certification exam. Sampling and Analytical requirements. OCWA follows a sampling and analysis schedule required by the ECA. Adherence to Ministry Guidelines and Procedures. To ensure the protection of the Public s health and operational excellence, OCWA adheres to the guidelines and procedures developed by the Ministry of Environment Mississippi Mills Lagoon and WWTP Systems 2012 Annual Report 13 of 15
