Executive Summary

This facility is aware of the requirements in the areas of Safety, Hazard Reviews, written Operating Procedures, Training, Maintenance, Compliance Audits, and Incident Investigations. To assist with ongoing compliance, a "Chemical Accident Prevention Compliance Manual" along with a Operations and Maintenance Manual have been prepared and implemented. Concerning the emergency response policy at the facility, the owner has made the decision that employees will not respond to accidental releases of regulated substances and will instead evacuate.



This facility is a waste water treatment plant. Treatment includes chlorination of the waste water with two chlorine cylinders located at the facility (2,000 lbs each). The process basically involves continuous mixing of chlorine with the waste water whereby the final mixture contains less than 1 % chlorine by weight. Waste water is additionally treated with sulphur dioxide, which is also a regulated substance. However, the sulphur dioxide stored on site is below threshold quantities. The treated waste water is then released. The storage cylinders and mixing equipment are subject to the RMP requirements since it contains threshold quantities of regulated substances



This facility has one worst case release scenario which involves the release of all substance contained in the single largest chlorine cylinder when full (2,000 lbs total). This scenario yields a distance to the endpoint of 3.0 miles. Section 3.1 of this RMP shows the calculations used for this scenario.



This facility has an alternative release scenario. The scenario involves a puncture of the largest diameter chlorine cylinder when full. The scenario yields a distance to the endpoint of 0.8 miles. Section 3.2 of this RMP shows the calculations used for this scenario.



The worst case release scenarios use the maximum capacity of the single largest vessel without administrative controls or mitigation measures to limit the volume or reduce the d
istance to the endpoint.



Since this facility is a Program 2, a documented prevention program is required. This program is discussed in a "Chemical Accident Prevention Compliance Manual" along with a Operations and Maintenance Manual prepared for the facility. The prevention program does discuss chlorine which is the specific chemical contained in an amount above the threshold quantity.



As documented in Section 4.0 of the RMP, the facility has not experienced a release as defined in the regulation within the past five years. Furthermore, the facility did not begin operations until January of 2011



Because chlorine storage is a Program 2 covered process, a written emergency response program is required. This program is contained in Section 5.0 of the "Chemical Accident Prevention Compliance Manual" prepared for the facility. Further, emergency response procedures have been developed and are contained at the front of this RMP and these procedures will be implemented in the event of an accidental release or the threat of such a release. Basically, the instructions are to evacuate the facility and then notify the proper authorities.



At present time, there are no planned changes to improve safety.
