Grand Valley Gas Plant - RMP Plan Executive Summary Executive Summary This executive summary is a brief overview of the Risk Management Program and the associated policies at the Barrett Resources (Barrett) Grand Valley Gas Plant. Emergency Response Policies The emergency response policies are represented in the Company Emergency Action Plan. Barrett takes an active role in preventing accidental releases at all of its facilities by ensuring that its employees are properly trained in the safe operation of covered processes and the safe handling of regulated chemicals. Barrett has established and maintained procedures for emergency notification and response. These are reviewed with employees on a periodic basis and revised to accommodate changes in staffing when they occur. Stationary Source and Regulated Substances The Grand Valley Gas Plant processes approximately 60 mmscf/day of natural gas. The station provides compression, dehydration, and recovery of liquid hydrocarbon compoun ds. The facility has three 30,000-gallon hydrocarbon product tanks, with a maximum intended inventory of 151,800 pounds in each. Release Scenarios The worst-case release scenario has been determined after careful review of the regulation and consideration of the storage vessel configuration at the facility. For the worst-case release scenario, the regulation is clear. The assumption is that the single largest container of a regulated substance (one of the 30,000-gallon hydrocarbon product tanks or 120,000 pounds) is released over a ten-minute period. No active mitigation may be considered. Worst-case meteorological conditions are also assumed to be present. The distance to the flammable endpoint (1-psi overpressure from a vapor cloud explosion) was determined to be 0.4 miles using the EPA RMP Comp. There are no residences, or public or environmental receptors within a 0.4-mile radius around the facility. Prevention Steps for Hydrocarbon Product and Natural Gas Condensate Since t his facility qualifies for Program 1 compliance, there are no regulatory requirements for a prevention program and chemical-specific prevention steps. Accident History Within the five-year period prior to the submittal of this RMP, there were no accidental releases of regulated flammable materials meeting the requirements of 40 CFR 68.42. Emergency Response Program This facility has established and maintains an emergency response program that is coordinated with local response agencies. The program is described in detail in the Company Emergency Action Plan and meets the requirement of 40 CFR 68.95. The goals of the program are to protect onsite employees from the hazardous effects of chemical releases and to minimize the effects of releases on the general public. The program is routinely reviewed and updated to reflect personnel and regulatory changes. Planned Changes for Improved Safety Ideas for changes to improve safety are actively sought from employees. Employee safety meet ings and training that focus on chemical and process safety issues are held periodically at this facility. Employees are encouraged and trained to recognize hazards and present ideas to eliminate them or to minimize the potential consequences of those hazards. |
