Albany Wastewater Plant - Executive Summary
General Executive Summary for Manufacturing: |
1. Accidental Release Prevention and Emergency Response Policies:
We at the the City of Albany Wastewater Plant are 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. Unforeseeably, if such a release does occur, our highly trained personnel are at hand to control and mitigate the effects of the release. We are also completely coordinated with the Albany Fire Department who provides additional emergency response expertise.
2. The Stationary Source and the Regulated Substances Handled:
The maximum inventory of chlorine that is expected to be present in this facility is 22,000 lbs.
he Worst Case Release Scenario and the Alternative Release Scenario, including administrative controls and mitigation measures to limit the distances for each reported scenario.
To perform the required offsite consequence analysis for our facility, we have used the look-up tables and equations provided by the EPA in the RMP Offsite Consequence Analysis Guidance. The following paragraphs provide details of the chosen scenarios.
Toxic Worst Case Analysis:
The Worst Case Scenario involves a catastrophic release from the Wastewater Treatment Plant's chlorine supply system. The scenario involves the release of 6,000 lb. of chlorine in a gaseous form over 10 minutes. The release rate (lbs/min) is calculated to be 600. A distance to endpoint of 3 miles is obtained which affects a residential population of 11,704 within this distance.
Toxic Alternative Case Analysis:
The Alternative Case Scenario involves a catastrophic release from the piping from a chlorine ton container to the chlo
rinator. The scenario involves the release of 10 lb. of chlorine in a gaseous form over 10 minutes. The release rate (lbs/min) is calculated to be 1 and a distance to endpoint of 0.06 miles is obtained which affects a residential population of 0.
There are no flammables Worst Case or Alternative Case Analysis for this facility.
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. One process at our facility is subject to the OSHA PSM standard under 29 CFR 1910.119. Our facility is also subject to EPCRA Section 302 notification requirements. The following sections briefly describe the elements of the release prevention program that is in place at our facility.
Process Safety Information:
The Wastewater Treatment Plant maintains a detailed record of safety information that describes t
he 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 analysis is the What-If Checklist. The studies are undertaken by a team of qualified personnel with expertise in engineering and process operations are revalidated at a regular interval of every three years. Any findings related to the hazard analysis are addressed in a timely manner.
For the purpose of safely conducting activities within our covered processes, the Wastewater 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 regula
rly reviewed and is readily accessible to operators involved in the processes.
The Wastewater Treatment Plant has a comprehensive training program in place to ensure that employees who are operating processes are properly trained in the procedures associated with these processes. New employees receive basic classroom training in process operations followed by on-the-job supervision until they are deemed competent to work independently. Refresher training is provided at least annually and more frequently as needed.
The Wastewater Treatment Plant carries out highly documented maintenance checks on process equipment to ensure proper operations. Process equipment examined by these checks includes: pressure vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems, controls and pumps. Maintenance operations are carried out by qualified personnel with previous training in maintenance practices. Furthermore, these pers
onnel 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 the Wastewater Treatment Plant to manage changes in process chemicals, technology, equipment and procedures. Process operators, maintenance personnel, or any other employee whose job tasks are affected by a modification of process conditions, are promptly made aware of, and offered, training to deal with the modification.
Pre-Startup Safety Reviews related to new processes and to modifications of established processes are conducted as a regular practice at the Wastewater 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.
The Wastewater Treatment Plant conducts audits on a regular basis
to determine whether the provisions set out under the RMP Rule are being implemented. 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.
The Wastewater Treatment Plant promptly investigates any incident that has resulted in, or courld 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.
The Wastewater Treatment Plant truly believes that process safety management and accident prevention require a team effort to be successful. Employees are strongly encouraged to express their views concerning accident prevention issues and to recommend improvements. In addition, our employees have access to all info
rmation created as part of our implementation of the RMP Rule, including information resulting from process hazard analysis in particular.
On occasion, the Wastewater Treatment Plant 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. The Wastewater Treatment Plant has a strict policy of informing the contractors of any known potential hazards related to the contractor's work and the processes. Contractors are also informed of all the procedures for emergency notification and evacuation, should an accidental release of chlorine occur.
5. Five-Year Accident History:
The Wastewater Treatment Plant has had an excellent record of preventing accidental releases over the last 5 years. Due to our stringent release prevention policies, there has not been an accidental release during the past 5 years.
Emergency Response Plan:
cility is included in the City of Albany's written emergency response plan. The Wastewater Treatment Plant has it's own written emergency response plan. The site emergency response plan includes specific procedures for informing the public and local agencies regarding responding to an accidental chlorine release. The emergency response plan includes information on emergency health care as well.
Date of the most recent review/update of the site emergency response plan: 5/28/1999
Date of the most recent emergency response plan training for employees is: 4/1/1999
The local agency coordinating the emergency response planning for the City of Albany is the Albany Fire Department. Their phone number is: 541-917-7700.
7. Planned Changes to Improve Safety:
Several developments and findings have resulted from the implementation of the various elements of our accidental release prevention program. We have upgraded our chlorine alarm and evacuation system and provided training for all
Public Works employees during April of 1999. We have also set up a system to provide better personnel accountability for visitors, vendors, and contractors who visit our facility.
