The Environmental Protection Agency (EPA) is issuing a final amendment to the leak detection and repair requirements allowing the use of optical gas imaging technology to locate emission leaks, the agency announced in a press release. The leaks are displayed on a video screen similar to the way night vision goggles are used to show the heat signature of objects. This amendment provides requirements for using the new technology; however, facilities may continue to use existing approved work practices to detect leaks.
This amendment modifies about 40 national rules requiring facilities to find and repair leaks from equipment, including pumps, valves, and connectors, from refineries, chemical production plants, and bulk liquid storage facilities. This amendment, which was proposed in 2006, will be effective upon publication in theFederal Register.
