City of Titusville Wastewater Treatment Plant - Executive Summary |
|
The City of Titusville Sewage Treatment Plant is designed to treat an average of 4.00 MGD. Wastewater treatment processes include chlorination for disinfection purposes. Chlorine usage at the plant ranges from 60-140 pounds per day depending on flow conditions. The maximum amount of chlorine maintained onsite is 8,000 pounds. A total of four, one-ton cylinders are normally maintained onsite. A worst case release scenario for the facility involves rupture of a 2,000 pound cylinder of chlorine. Results of ALOHA modeling indicate offsite receptors within a 2.2 mile radius may be affected by a release under this scenario. An alternate release scenario involves a broken valve on a chlorine cylinder. Values obtained from RMP guidance indicates the toxic end point for an alternate release from the facility would be 0.2 miles. The facility has an emergency Offsite Response Plan prepared in conjunction with the Crawford County LEPC. There have been no reportable accidents involving ch lorine at the facility within the past five years. |
