Alternative Work Practice To Detect Leaks From Equipment

Numerous EPA air emissions standards require specific work practices for equipment leak detection and repair. On April 6, 2006, we proposed a voluntary alternative work practice for leak detection and repair using a newly developed technology, optical gas imaging. The alternative work practice is an alternative to the current leak detection and repair work practice, which is not being revised. The proposed alternative has been amended in this final rule to add a requirement to perform monitoring once per year using the current Method 21 leak detection instrument. This action revises the General Provisions to incorporate the final alternative work practice.
