Summary: Risk Management Plan 
South Central Wastewater Authority (SCWWA) 
 
The purpose of this document is to provide the South Central Wastewater Authority with a training, operations and emergency response plan should a release of chlorine gas occur at the Pocahontas Island Facility. This plan is also available to interested persons, including the public, demonstrating that this facility is complying with the Environmental Protection Agency (EPA) Accidental Release Prevention Requirements, Risk Management Programs under the Clean Air Act Section 112(r)(7). This regulation is published in 40 CFR Part 68. 
 
There is one regulated substances at this facility, chlorine, that is above the threshold quantities specified in Section 68.130 of 40 CFR Part 68, and therefore this facility must comply with the risk management program. Chlorine is used to disinfect the treated effluent from the wastewater facility prior to discharge to the Appomattox River. There have been no releases of chlorine f 
rom this facility for the past five years. SCWWA has assessed and continues to assess hazards to determine how accidental releases can impact the public health and environment. If after reading this program, you find that improvements can be made, please contact this organization. 
 
The Program 3 eligibility criteria applies to facilities where:  
 
7 The facility is already covered under OSHA's Process Safety Management (PSM) standard.  
7 The Standard Industrial Classification (SIC) code for this facility is 4952  
7 The North American Industry Classification System (NAICS) for this facility is 221.  
 
The following elements have been completed as they apply to this facilities Program 3 operations:  
 
7 The single RMP, including registration that covers the chlorination  process and chlorine (40 CFR 68.12(d)).  
7 The management system as provided in 40 CFR 68.12(d)(1).  
7 The hazard assessment as provided in 40 CFR 68.12(d)(2). 
7 The Program 3 Prevention Program as provided in 40 CFR 68.12( 
d)(3). 
7 How emergency response procedures are coordinated with the Petersburg, Fire, Rescue, and Emergency Services. 
7 The data on prevention program elements as described in 40 CFR 68.12(d)(5). 
 
The worst case scenario is loss of a one ton cylinder in ten minutes  which could impact an area within a radius of the plant of 0.9 mile depending on the wind speed and direction. The alternate release scenario would be a pigtail disconnecting from a cylinder. The release from this scenario would impact an area within 0.2 miles of the plant. The building which houses the chlorine cylinders and process equipment is secured at all times. The process equipment is constantly monitored by plant employees. It was installed in 1996 and is considered state of the art.  
 
No modifications to the facility are planned in the near future. Personnel training, process and chemical awareness and monitoring will continue to be emphasized to minimize both the on and off site consequences of a chemical releas
