As part of the Safe Drinking Water Act, the Environmental Protection Agency revised the Disinfection Byproduct (DBP) Rule. Trihalomethanes (THMs) are governed by this rule, and the compliance date for the new calculation method for compliance is April 1, 2012. The City of Henderson believes that various factors about the source water (primarily lower Lake Mead water levels) and the distribution system may make it difficult to meet the revised regulation in some locations until planned system upgrades are complete. As allowed by federal law, the City of Henderson has requested a two-year extension for compliance with the new rule in order to complete construction of a third intake. The extension will begin April 1, 2012, and end March 31, 2014. To receive further information or to provide comment on the Public Notice for Extension, click here.
