A. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report must be performed in accordance with the techniques prescribed in 40 CFR Part 136, unless otherwise specified in an applicable categorical pretreatment standard.

B. If 40 CFR Part 136 does not contain sampling or analytical techniques for a pollutant, or if the EPA determines that its sampling and analytical techniques are inappropriate for that pollutant, sampling and analyses of the pollutant must be performed using validated analytical methods or any other applicable sampling and analytical procedures, including procedures recommended by the Director or other parties approved by EPA and the State.
