Cambridge Water Treatment Plant - Executive Summary |
|
The City of Camridge is committed to complying with Section 112(r) of the Clean Air Act relative to preparing Risk Management Plans (RMPs). The City entered into an agreement with Civil Design Associates, Inc. to assist them with preparing the required documents. The City of Cambridge is developing accidental release prevention and emergency response policies for the water treatment plant chlorination facility. These documents are on file at the City Engineer's office, Utility Director's office and the water treatment plant. The City is committed to make this facility as safe as possible for the residents and employees. The water treatment plant utilizes chlorine to purify the drinking water distributed to our Community. The facility has the capacity to store twelve one ton cylinders of liquid chlorine or 24,000 pounds, although only one cylinder is active and one cylinder is connected for standby at any one time. Accident release scenarios were evaluated for this facility by u se of the RMP Offsite Consequence Analysis (OCA) Guideance. Also, the Guernsey County EMA/LEPC prepared release scenarios in 1995 utilizing CAMEO modeling. Although the worst case scenario assumes release of all 24,000 pounds of chlorine, this is highly unlikely due to the use, daily checking of equipment and alarm system setup. A more likely worst case (alternate release scenario) is release of the contents of a one cylinder or 2000 pounds of chlorine. The chlorination facilities are housed in a block building at the plant site and are completely isolated due the hazard involved. If a release occurred it could have offsite impact. The Guernsey County EMA/LEPC performed their release scenario to evaluate and prepare the emergency response procedure needed and be aware of the impacted area. The City is always reviewing the prevention programs and procedures in place to make them better in the best interest of the employees and residents. We have recently reviewed the procedures relative to the water treatment plant chlorination facility and are improving them at the present time. During the past five year period we are pleased to inform you that no accidental releases have occurred at this facility. Our emergency response program and relationship with the Guernsey County EMA/LEPC have been breifly described throughout this portion of this document. If an accidental release should occur, the procedures are in place to provide notification and assistance to all effected citizens. At the present time no improvements to the chlorination facility are planned. To the best of the undersigned's knowledge, information, and belief formed after reasonable inquiry, the information submitted is true, accurate, and complete. Jeannette M. Wierzbicki, P.E.
