Idaho Admin. Code r. 58.01.25.370 - PRETREATMENT STANDARDS

01. Purpose and Applicability. This section and 40 CFR Part 403 apply to: (3-24-22)

a. Pollutants from non-domestic sources covered by Pretreatment Standards which are indirectly discharged into or transported by truck or rail or otherwise introduced into POTWs as defined in Subsection 370.04 and 40 CFR 403.3; (3-24-22)

b. POTWs which receive wastewater from sources subject to National Pretreatment Standards; and (3-24-22)

c. Any new or existing source subject to Pretreatment Standards. National Pretreatment Standards do not apply to sources which discharge to a sewer which is not connected to a POTW Treatment Plant. (3-24-22)

02. Objectives of General Pretreatment Regulations. This section and 40 CFR Part 403 fulfill three (3) objectives: (3-24-22)

a. To prevent the introduction of pollutants into POTWs which will interfere with the operation of a POTW, including interference with its use or disposal of municipal sludge; (3-24-22)

b. To prevent the introduction of pollutants into POTWs which will pass through the treatment works or otherwise be incompatible with such works; and (3-24-22)

c. To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges. (3-24-22)

03. Department Program in Lieu of a POTW Program. 40 CFR 403.8(a) requires certain POTWs develop a pretreatment program. The Department may, however, assume responsibility for implementing the POTW pretreatment program requirements set forth in 40 CFR 403.8(f) in lieu of requiring the POTW to develop a pretreatment program. This does not preclude POTWs from independently developing pretreatment programs. (3-24-22)
