City of Chanute Water Treatment Plant - Executive Summary |
|
Only covered chemical is 10,250 pounds chlorine. Worst-case radius is 1.3 miles; alternative scenario radius is 0.2 mile. Populations in these radii are 3,700 and 590, respectively. Treatment plant uses written procedures for chlorine cylinder replacement and monitors building for chlorine leakage. There have been no accidents in the past 5 years. EXECUTIVE SUMMARY We have adopted this Program in order to implement 40 C.F.R. 68, the federal requirements regulating Risk Management of Highly Hazardous Chemicals. This Program will help prevent the occurrence of, or minimize the consequences of, catastrophic releases by stating our policies and procedures for the management process hazards in start-up, operation, inspection, maintenance, and the other matters addressed in the federal standard. Accidental Release Prevention and Emergency Response Policies The City of Chanute believes that preventative maintenance is the key to minimizing the potential for accidental releases. A Standar d Operating Procedure (SOP) has been reviewed and revised to enable the employees to handle chlorine in a safe and efficient manner. The Chanute Water Treatment Plant has chosen to be a non-responding facility in the event of an emergency. Responsibility for emergency response to an accidental release has been given to the Chanute Police and Fire Departments and the State and Local Emergency Response Centers. Stationary Sources and Regulated Substances. The Chanute Water Treatment Plant utilizes chlorine and ammonia as disinfectants for the treated drinking water. The maximum inventory and threshold quantities for these chemicals are shown below. Chemical Maximum Inventory (lb.) Threshold Quantity (lb.) Chlorine 10,250 2,500 Offsite Consequence Analysis The offsite consequent analysis includes a worst-case scenario and an alternative release scenario as defined in 40 C.F.R 68. RMP*COMP was used to determine endpoint distances for both sc enarios. RMP*COMP Input Parameters Worst-Case Scenario- Chlorine Alternative Scenario- Chlorine Liquefied/ unliquefied unliquefied unliquefied Release rate, lb/min 200 90 Release rate calculation method open air enclosed in building Rural or urban terrain urban urban Release duration, minutes 10 min 10 min End Point (mg/l) 0.0087 0.0087 The results of the RMP*COMP are summarized in the table along with estimated population within the impact area. The population data was estimated using the Block Centroid Density Group Method in Landview for the worst-case scenario. RMP*COMP Output Results Worst Case Scenario - Chlorine Alternative Scenario - Chlorine Impact Radius (miles) 1.3 0.2 Estimated Population within Impact Area 3,700 590 Hazard Analysis The City of Chanute has compiled a Hazard Analysis to minimize releases. This Program includes; safety information on the covered chemicals, hazard reviews, operating and maintenance schedules, training, compliance audits, incid ent investigations, and emergency response procedures. Five-year Accident History In the last 5 years the Chanute Water Treatment Plant has had no accident from the covered processes that resulted in deaths, injuries, evacuations, sheltering-in-place, property damage, or environmental damage.
