1. Open for Comment: Proposed Sufficiently Sensitive Methods Rulemaking

EPA is proposing minor amendments to the CWA regulations to codify that under the NPDES program, only ?sufficiently sensitive? analytical test methods can be used when completing an NPDES permit application and when performing sampling and analysis pursuant to monitoring requirements in an NPDES permit. On June 23, 2010 EPA issued a Federal Register Notice announcing the proposed amendments to the CWA, and the public will have 45 days to comment on the proposed rulemaking. View the Federal Register Notice and more information at http://cfpub.epa.gov/npdes/ssmethods.cfm
