New EPA Reg's current data The Environmental Protection Agency (EPA) has published regulations which may affect analytical methods used by environmental testing laboratories. CFR listings for recent regulations are given below.For complete texts see: March 26, 2007: 40 CFR Parts 136 and 503
Guidelines Establishing Test Procedures for the Analysis of Pollutants in Wastewater and Sewage Sludge; Final Rule Summary: This rule modifies the EPA’s Guidelines that establish approved bacterial testing procedures for analysis and sampling under the Clean Water Act. These changes include approval of new methods for monitoring microbial pollutants in wastewater and sewage sludge, including EPA methods, vendor-developed methods, and methods developed by voluntary consensus bodies (VCSB) as well as updated versions of currently approved methods. Effective date: April 25, 2007
March 12, 2007: 40 CFR Part 122, 136, et al.
Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act; National Primary Drinking Water Regulations; and National Secondary Drinking Water Regulations; Analysis and Sampling Procedures; Final Rule Summary: This rule modifies the testing procedures approved for the analysis and sampling under the Clean Water Act and Safe Drinking Water Act. The Clean Water Act changes adopted in this final rule fall into the following categories: new vendor-developed methods as well as EPA and voluntary consensus standard bodies (VCSB) methods, updated versions of currently approved methods, revisions to method modification and analytical requirements, withdrawal of certain outdated methods, and changes to sample collection, preservation, and holding time requirements. This rule also changes regulations under the Safe Drinking Water Act that establish drinking water sampling and analysis procedures. The changes include approval of vendor-developed methods, new EPA and VCSB methods, updated VCSB methods, and approval of a modification to the test kit used with Syngenta Method AG-625 that restricts its use in certain circumstances. Effective dare: April 11, 2007
January 4, 2007: 40 CFR Parts 9, 141, and 142
Unregulated Contaminant Monitoring Regulation (UCMR) for Public Water Systems Revisions: Final Rule Summary: This final rule describes the design for the second Unregulated Contaminant Monitoring Regulation (UCMR) cycle (i.e., UCMR 2) of 2007-2011. EPA is requiring monitoring of 25 chemicals using 5 different analytical methods. UCMR 2 monitoring will occur during 2008-2010. Effective date: February 5, 2007 Corrections: January 26, 2007: 40 CFR Part 141
November 8, 2006: 40 CFR Parts 9, 141 and 142 National Primary Drinking Water regulations: Ground Water Rule; Final Rule Summary: The Environmental Protection Agency is promulgating a National Primary Drinking Water Regulation, the Ground Water Rule, to provide for increased protection against microbial pathogens in public water systems that use ground water sources. This final rule promulgates regulations requiring disinfection as a treatment for all public water systems, including surface water systems and, as necessary, ground water systems. The Ground Water Rule establishes a risk-targeted approach to target ground water systems that are susceptible to fecal contamination, instead of requiring disinfection for all ground water systems. The occurrence of fecal indicators in a drinking water supply is an indication of the potential presence of microbial pathogens that may pose a threat to public health. This rule requires ground water systems that are at risk of fecal contamination to take corrective action to reduce cases of illnesses and deaths due to exposure to microbial pathogens. Effective date: January 8, 2007 Compliance date: December 1, 2009 Corrections: November 21, 2006 40 CFR Part 141
January 5, 2006: 40 CFR Parts 9, 141, 142
National Primary Drinking Water Regulations: Long Term 2 Enhanced Surface Water Treatment Rule; Final Rule Summary: EPA is promulgating National Primary Drinking Water Regulations that require the use of treatment techniques along with monitoring, reporting, and public notification requirements for all public water systems that use surface water sources. The purposes of the Long Term 2 Enhanced Surface Water Treatment Rule are to protect public health from illness due to Cryptosporidium and other microbial pathogens in drinking water and to address risk-risk trade-offs with the control of disinfection byproducts. Effective date: March 6, 2006 Corrections: January 30, 2006: 40 CFR Parts 9, 141, and 142 and February 6, 2006: 40 CFR Parts 9, 141, and 142
January 4, 2006: 40 CFR Parts 9, 141, and 142
National Primary Drinking Water Regulations: Stage 2 Disinfectants and Disinfection Byproducts Rule; Final Rule Summary: The final Stage 2 Disinfectants and Disinfection Byproducts Rule contains maximum contaminant level goals for chloroform, monochloroacetic acid, and trichloroacetic acid; National Primary Drinking Water Regulations, which consist of maximum contaminant levels (MCLs) and monitoring, reporting, and public notification requirements for total trihalomethanes (TTHM) and haloacetic acids (HAA5); and revisions to the reduced monitoring requirements for bromate. This document also specifies the best available technologies for the final MCLs. EPA is also approving additional analytical methods for the determination of disinfectants and disinfectant byproducts in drinking water. Effective date: March 6, 2006 Corrections: June 29, 2006: 40 CFR Part 141 |
