Trenton Water Works Filtration Plant treats raw water from the Delaware River. During the treatment process chlorine is used to disinfect the water. The liquid chlorine is extracted from 1- ton containers, evaporated into a gas, and injected into the water. There is never more that 2000 lbs of chlorine available to the system at any one time. There have been no reportable incidents in the past 5 years. The Worst case scenario release of chlorine is .9 miles by RMP COMP. The alternate case scenario release is .1 miles by RMP COMP. A Hazard Analysis and Risk Assesment Review conducted on 7/24/96 demonstrated that with the actual release prevention mechanisms and mitigation measures incorporated at this facility, the above worst case and Alternative case scenarios are implausible. Trenton Water Works plans no safety improvements at this time because all current state of the art for design and operation is implemented. |
