Accidental Release Prevention and Emergency Response Policies We at Evanston Water Treatment Plant are strongly committed to employee, public and environmental safety. This commitment is demonstrated by our comprehensive accidental release prevention program that covers areas such as design, installation, operating procedures, maintenance, and employee training associated with the processes at our facility. It is our policy to implement appropriate controls to prevent possible releases of regulated substances. 2. The Stationary Source and the Regulated Substances Handled Our facility's primary activities encompass Treatment of drinking water. We have 1 regulated substances present at our facility. These substances include and Chlorine. Chlorine is used for disinfection of drinking water. The maximum inventory of Chlorine at our facility is 16000.00 lb.. 3. The Worst Case Release Scenario(s) and the Alternative Release S cenario(s), including administrative controls and mitigation measures to limit the distances for each reported scenario To evaluate the worst case scenarios, we have used the EPA's RMP*Comp(TM). For alternative release scenario analyses we have employed Areal Locations of Hazardous Atmospheres [ALOHA(R)]. The following paragraphs provide details of the chosen scenarios. The worst case release scenario submitted for Program 2 and 3 toxic substances as a class involves a catastrophic release from the Chlorine injection process. In this scenario 2000 lb. of Chlorine is released. The toxic liquid released is assumed to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to evaporate over 10 minutes. Passive mitigation systems such as enclosure(s) are also taken into account to calculate the scenario. These mitigation systems have the effect of containing the chlorine. At Class F atmospheric stability and 1.5 m/s windspeed, the maximum distance of 0.9 miles is obtained corresponding to a toxic endpoint of 0.0087 mg/L. The alternative release scenario for Chlorine involves a release from mishandling a cylinder during unloading. The scenario involves the release of 2000 lb. of chlorine. Toxic liquid is assumed to be released to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to have evaporated after 1 minute. Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.0087 mg/L of Chlorine is 2.3 miles. 4. The General Accidental Release Prevention Program and the Chemical-Specific Prevention Steps Our facility has taken all the necessary steps to comply with the accidental release prevention requirements set out under 40 CFR part 68 of the EPA. This facility was designed and constructed in accordance with Generally recognized practices for water treatment facilities. The following sections briefly describe the elements of the release prevention program that is in place at our stationary source. Process Safety Information Evanston Water Treatment Plant maintains a detailed record of safety information that describes the chemical hazards, operating parameters and equipment designs associated with all processes. Process Hazard Analysis Our facility conducts comprehensive studies to ensure that hazards associated with our processes are identified and controlled efficiently. The methodology used to carry out these analyses is What If/Checklist (combined) and HAZOP. The studies are undertaken by a team of qualified personnel with expertise in engineering and process operations and are revalidated at a regular interval of five years. Any findings related to the hazard analysis are addressed in a timely manner. The most recent PHA/update was performed on 02/12/1998. Operating Procedures For the purposes of safely conducting activities within our covered processes, Evanston Water Treatment Plant maintains written operating procedures. These procedures address various modes of operation such as initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown and startup after a turnaround. The information is regularly reviewed and is readily accessible to operators involved in the processes. Training Evanston Water Treatment Plant has a comprehensive training program in place to ensure that employees who are operating processes are competent in the operating procedures associated with these processes. Refresher training is provided at least every three years and more frequently as needed. Mechanical Integrity Evanston Water Treatment Plant carries out highly documented maintenance checks on process equipment to ensure proper operations. Process equipment examined by these checks includes among others; pressure vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems, controls and pumps. Maintenance operations are carried out by qual ified personnel with previous training in maintenance practices. Furthermore, these personnel are offered specialized training as needed. Any equipment deficiencies identified by the maintenance checks are corrected in a safe and timely manner. Management of Change Written procedures are in place at Evanston Water Treatment Plant to manage changes in process chemicals, technology, equipment and procedures. The most recent review/revision of maintenance procedures was performed on 06/02/1999. Process operators, maintenance personnel or any other employee whose job tasks are affected by a modification in process conditions are promptly made aware of and offered training to deal with the modification. Pre-startup Reviews Pre-start up safety reviews related to new processes and to modifications in established processes are conducted as a regular practice at Evanston Water Treatment Plant. These reviews are conducted to confirm that construction, equipment, operating and maintenance procedures are suitable for safe startup prior to placing equipment into operation. Compliance Audits Evanston Water Treatment Plant conducts audits on a regular basis to determine whether the provisions set out under the RMP rule are being implemented. The most recent comliance audit was conducted on 06/03/1999. These audits are carried out at least every 3 years and any corrective actions required as a result of the audits are undertaken in a safe and prompt manner. Incident Investigation Evanston Water Treatment Plant promptly investigates any incident that has resulted in, or could reasonably result in a catastrophic release of a regulated substance. These investigations are undertaken to identify the situation leading to the incident as well as any corrective actions to prevent the release from reoccurring. All reports are retained for a minimum of 5 years. Employee Participation Evanston Water Treatment Plant truly believes that process safety management and accident preve ntion is a team effort. Company employees are strongly encouraged to express their views concerning accident prevention issues and to recommend improvements. In addition, our employees have access to all information created as part of the facility's implementation of the RMP rule, including information resulting from process hazard analyses in particular. Contractors On occasion, our company hires contractors to conduct specialized maintenance and construction activities. Prior to selecting a contractor, a thorough evaluation of safety performance of the contractor is carried out. Evanston Water Treatment Plant has a strict policy of informing the contractors of known potential hazards related the contractor's work and the processes. Contractors are also informed of all the procedures for emergency response should an accidental release of a regulated substance occur. 5. Five-year Accident History Evanston Water Treatment Plant has had an excellent record of preventing accidenta l releases over the last 5 years. Due to our stringent release prevention policies, there have been no accidental releases during this period. 6. Emergency Response Plan Evanston Water Treatment Plant carries a written emergency response plan to deal with accidental releases of hazardous materials. The plan includes all aspects of emergency response including adequate first aid and medical treatment, evacuations, notification of local emergency response agencies and the public, as well as post-incident decontamination of affected areas. To ensure proper functioning, our emergency response equipment is regularly inspected and serviced. In addition, the plan is promptly updated to reflect any pertinent changes taking place within our processes that would require a modified emergency response. Uinta County LEPC is the Local Emergency Planning Committee (LEPC) with which our emergency plan has been coordinated and verified. * Process Chemicals Process ID: 2410 Description: Chlorine injection Process Chemical ID: 2564 Program Level: Program Level 3 process Chemical Name: Chlorine CAS Number: 7782-50-5 Quantity (lbs): 16000 CBI claimed: Flammable/Toxic: TOXIC * Process NAICS Process ID: 2410 Process NAICS ID: 2460 Program Level: Program Level 3 process NAICS Code: 22131 NAICS Description: Water Supply and Irrigation Systems ***** Section 2.
