In August 2010 the EPA issued a notice proposing new and revised analytical methods to be used under the Clean Water Act (CWA).
The proposed rule, entitled “Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act; Analysis and Sampling Procedures”, will affect numerous EPA Methods, ASTM Methods, Standard Methods, and alternative test methods.
EPA methods:
EPA has announced plans to require reporting for hydrogen sulfide (H2S) and is accepting public comments until April 27, 2010. Under the Toxic Release Inventory (TRI) requirements of the Emergency Planning and Community Right-to-Know Act (EPCRA), the EPA will require H2S reporting estimates of all on-site releases and off-site transfers for disposal by each facility that meets the manufacture thresholds for hydrogen sulfide. Manufacturing limits for H2S emissions are 25,000 pounds per year, process limits are 25,000 pounds per year, and “other” use is 10,000 pounds per year.
