• Proposed changes include minor correction to Stage 2 Disinfectants and Disinfection Byproducts Rule and changes in references to analytical methods

WASHINGTON, DC, Nov. 14, 2008 -- As published in the Federal Register, EPA is proposing to make a minor correction to the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR) and make minor, unrelated, changes in references to expedited, alternative methods and other analytical methods in the regulations.

EPA promulgated the Stage 2 Disinfectants and Disinfectant Byproducts Rule on January 4, 2006. A requirement for ground water systems serving 500- 9,999 people was unintentionally excluded from the final rule. As a result, the rule allowed for less routine compliance monitoring than intended for this category of Public Water Systems (PWSs). These PWSs should have been required to monitor for both total trihalomethanes (TTHM) and haloacetic acids (HAA5) concentrations at two locations. Due to the error, they were only required to monitor for either TTHM or HAA5 at two locations.

EPA is also proposing to make minor, unrelated changes in the CFR by adding references to the list of methods approved under the Expedited Approval Process, removing references to outdated methods, and specifying a new source for the publication titled Technical Notes on Drinking Water Methods.

The comment period is open. Comments must be received on or before January 13, 2009.
