U.S. Environmental Protection Agency (EPA) Region 8 Drinking Water Laboratory Certification Program
See national section for basic information and federal regulations.
Comparison: State vs. Federal
· Rules. Because Wyoming does not have primacy from EPA to administer its drinking water program, laboratories that perform water analysis for Wyoming public drinking water systems or for tribal drinking water systems must be certified by EPA in Region 8. Laboratories that are located outside of Region 8 may be used as long as another state or EPA region certifies them and the laboratory has applied for and been granted reciprocal certification with Region 8.
Wyoming has been granted authority to administer the National Pollutant Discharge Elimination Program (NPDES) in the state, where it is known as WYPDES. Wyoming follows the federal monitoring requirements for the NPDES program. See the national section BIOASSAYS/BIOMONITORING.
· Administration and enforcement. EPA Region 8 administers the laboratory certification program in Wyoming. DEQ administers the WYPDES permitting program.
