Alternative Work Practice (AWP)

40 CFR Part 60 A sec 60.18(g)

The Alternative Work Practice is an EPA approved method that allows for Optical Gas Imaging along with one annual Method 21 survey to be used in lieu of a full Method 21 LDAR program. Our model using the ‘AWP’ allows us to reduce facility emissions while saving LDAR programs up to 35% on their LDAR budget. We have over 20 years of combined experience utilizing the AWP at Processing and LNG Export facilities.

The AWP can be used for any regulation in 40 CFR Parts 60, 61, 63, and 65 that requires Method 21 monitoring. For more information about the AWP, CLICK HERE

“Numerous EPA air pollution standards require specific work practices for equipment leak detection and repair (LDAR). [Method 21] requires the use of a monitor which meets required performance specifications. This work practice is based on 25-year-old technology. New technology has been developed which we believe provides equal, or better, environmental protection than that provided by [Method 21]. This action proposes a voluntary alternative work practice (AWP) for finding leaking equipment using optical gas imaging.”
