�� Attachment"A" -Scope of Services City of Decatur,uiinois June, 1999 encourage sources to reduce the probability of accidental releases of substances that have the potential to cause immediate harm to public health and to the environment,and will stimulate the dialogue between industry and the public to improve accident prevention and emergency response practices. Chlorine is identified on the "List of Regulated Toxic Chemicals and Threshold Quantities for Accident Release Prevention." The RMP threshold quantity for chlorine is 2,500 pounds. Since the City of Decatur's South Water Treatment Plant normally stores chlorine in excess of its threshold quantity,the facility is subject to OSHA's Process Safety Management standard and USEPA's RMP rule. The chlorine process is eligible for RMP"Program 3". A Program 3 Risk Management Program requires development of the following elements: • Submission of a single Risk Management Plan reflecting all covered processes; • Development and implementation of a management system; • Conduct of a hazard assessment; • Submission of information regarding the process 5-year accident history; • Implementation of Program 3 prevention requirements; • Development and implementation of an emergency response program; and • Submission of data regarding Program 3 prevention requirements.

As defined in 168.3, "Definitions," covered process means "a process that has a regulated substance present in more than a threshold quantity as determined under¶68.115 of this part."
