(A) Purpose and Policy

This ordinance sets forth uniform requirements for users of the Publicly Owned Treatment Works for Clayton County and enables Clayton County Water Authority to comply with all applicable State and Federal laws, including the Clean Water Act (33 United States Code § 1251 et seq.) and the General Pretreatment Regulations (40 Code of Federal Regulations Part 403). The federally mandated objectives of this ordinance are:

  • To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will interfere with its operation;
  • To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will pass through the Publicly Owned Treatment Works, inadequately treated, into receiving waters, or otherwise be incompatible with the Publicly Owned Treatment Works;
  • To protect both Publicly Owned Treatment Works personnel who may be affected by wastewater and sludge in the course of their employment and the general public;
  • To promote reuse and recycling of industrial wastewater and sludge from the Publicly Owned Treatment Works;
  • To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the Publicly Owned Treatment Works; and
  • To enable Clayton County Water Authority to comply with its National Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other Federal or State laws to which the Publicly Owned Treatment Works is subject.

This ordinance provides rules for regulating the use of public sewers and drains, sewer service charges, industrial waste surcharges, connection of building sewers, and the discharge of water and waste into the public sewer system(s). This ordinance shall apply to all users of the Publicly Owned Treatment Works. The ordinance authorizes the issuance of wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.

    3. Upon a finding that a user meeting the criteria in Subsection (b) has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, CCWA may at any time, on its own initiative or in response to a petition received from a user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant industrial user.
