The U.S. Environmental Protection Agency is issuing a final amendment to the
leak detection and repair requirements allowing the use of optical gas imaging
technology to locate emission leaks, according to 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 the Federal Register.
