Comparison: State vs. Federal
• Rules. Texas requires biological monitoring of toxic effluents using federally approved testing methods under provisions of the Texas surface water quality standards. The Texas toxic effluent regulations include a provision authorizing TCEQ to include biomonitoring requirements in permits. Actual testing requirements are decided on a case-by-case basis and are set out in each facility's permit. See the national section BIOASSAYS/BIOMONITORING and the terms of your discharge permit, and contact TCEQ for additional guidance.
The state has also developed regulations for environmental testing laboratory accreditation and certification. Environmental laboratories supplying data for decisions relating to compliance with the Safe Drinking Water Act (SDWA) must be certified by TCEQ.
