submitted the RMP to EPA in February 1999. The RMP must be reviewed and recertified by EPA every 5 years. The Manteca WQCF RMP was last revised and recertified in June 2004. RMP Hazard and Operability Study The WQCF's Hazard and Operability Study(HAZOP)was a systematic investigation that identified risks of potential releases of acutely hazardous materials at the plant. The HAZOP focused on the safety of the WQCF's use of chlorine and sulfur dioxide, as these are the chemicals that represent the greatest public health and safety risk. The study identified potential chemical release points and then addressed possible improvements in plant safety by documenting additional risk reduction methods that could be employed. The HAZOP included the plant's chlorine and sulfur dioxide cylinder offloading and storage,replacement,and water treatment procedures. The HAZOP study resulted in findings and recommendations to improve the operability and safety of the processes analyzed. These were included in prevention/mitigation measures and a schedule of implementation, and were committed to by the WQCF wastewater systems superintendent for completion in accordance with the schedule. Hazard Assessment The purpose of the hazard assessment is to evaluate the risk of a theoretical accidental chemical release, specifically a release of chlorine or sulfur dioxide. The report further developed information presented in the HAZOP study by determining the actual risk of plausible release events of chlorine and sulfur dioxide to off-site receptors. The assessment concluded that no further planning appeared to be justified based on the adequacy of existing safety and training measures already in place and the lack of a record of releases having occurred at the facility. Training The WQCF has a documented training program in place. The training program is designed to keep all appropriate employees fully capable of preventing and mitigating an incident that could result in safety or environmental problems. It is also designed to give personnel the skills to prevent a small incident at the facility from becoming one that causes adverse off-site consequences. It is fully revised on a biannual basis. Relevant sections are also reviewed as required by an incident investigation.New employees are given training by the superintendent or a designated person. Existing personnel attend twice-monthly safety meetings. The record of training is kept on safety meeting forms. RMP Audit and Inspection Program The WQCF currently has an audit and equipment inspection program organized to maintain compliance with federal, state, and local regulations, as well as to maintain a safe work environment. The RMP manager is responsible for performing a semiannual audit of the WQCF to ensure that prevention program elements have been implemented. In addition,WQCF staff perform quarterly safety audits of the entire facility. The audits are intended to ensure that proper safety measures are being taken to provide a safe workplace for all personnel and to minimize the potential for accidents. Routine equipment inspections are coordinated by the maintenance supervisor. Routine inspections of all of the regulated substance handling equipment are conducted for serviceability, and to identify potential problems that could result in a regulated substance release. Hazardous Materials Management Plan The WQCF developed and submitted a Hazardous Materials Management Plan(HMMP)to the SJCOES. The HMMP is updated regularly as hazardous materials inventory changes occur, and is intended to minimize the potential for employee exposure or public exposure to an actual or threatened hazardous material release at the EDAW Manteca WQCF and Collection System Master Plans EIR Hazards and Hazardous Materials 4.6-8 City of Manteca
