Section 1200. - General provisions.

A. Purpose and Policy. This chapter sets forth uniform requirements for Users of the Publicly Owned Treatment Works for the City of Tulsa and enables the City of Tulsa to comply with all applicable state and federal laws, including the Clean Water Act, 33 U.S.C., Section 1251, et seq.; and the General Pretreatment Regulations, Title 40 Code of Federal Regulations (C.F.R.) Part 403. The objectives of this chapter are: 1. To prevent the introduction of pollutants into the Publicly Owned Treatment Works (POTW) that will interfere with its operation; 2. To prevent the introduction of pollutants into the POTW that will pass through the POTW, inadequately treated, into receiving waters, or otherwise be incompatible with the POTW; 3. To protect both POTW personnel who may be affected by wastewater and biosolids in the course of their employment and the general public; 4. To promote reuse and recycling of industrial wastewater and biosolids from the POTW; 5. To promote the use of pollution prevention practices; and 6. To enable the City of Tulsa, the Tulsa Metropolitan Utility Authority and the Regional Metropolitan Utility Authority to comply with its Oklahoma Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the POTW is subject. This chapter shall apply to all Users of the POTW. The chapter authorizes the issuance of wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires User reporting; provides for the setting of fees for the equitable distribution of costs resulting from the program established in this chapter and encourages the use of pollution prevention practices. B. Administration. Except as otherwise provided in this chapter, the Water and Sewer Director of the City of Tulsa shall administer, implement, and enforce the provisions of this chapter.

New Source. 1. Any building, structure, facility, or installation from which there is (or may be) a discharge of pollutants, the construction of which commenced after the publication of proposed Pretreatment Standards under Section 307(c) of the Act which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that: a. The building, structure, facility, or installation is constructed at a site at which no other source is located; b. The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or c. The production or wastewater generating processes of the building, structure, facility, or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source, should be considered. 2. Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of subparagraphs 1.b or 1.c, of this definition, but otherwise alters, replaces, or adds to existing process or production equipment. 3. Construction of a New Source as defined under this definition has commenced if the owner or operator has: a. Begun, or caused to begin, as part of a continuous onsite construction program, (1) Any placement, assembly, or installation of facilities or equipment; or (2) Significant site preparation work including clearing, excavation, or removal of existing buildings, structures, or facilities, which is necessary for the placement, assembly, or installation of new source facilities or equipment; or b.

Pollution Prevention. The use of materials, procedures or practices that reduce or eliminate the concentration of pollutants or waste at the source. The hierarchy for the management of wastes is: Source Reduction, Recycling, Treatment, and Disposal. Source Reduction is considered to be the most desirable and Disposal the least desirable waste management practice. Pretreatment. The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in lieu of, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable Pretreatment Standard.

Is designated as such by the City on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any Pretreatment Standard or requirement. 3. Upon a finding that a User meeting the criteria in paragraph 2. of this definition, has no reasonable potential for adversely affecting the POTW's operation or for violating any Pretreatment Standard or requirement, the City 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 C.F.R. § 403.8(f)(6), determine that such User should not be considered a Significant Industrial User. 4. The Director may determine that an Industrial User subject to Categorical Pretreatment Standards is a Non-Significant Categorical Industrial User rather than a Significant Industrial User, on a finding that the Industrial User never discharges more than 100 gallons per day (gpd) of total Categorical wastewater (excluding domestic, non-contact cooling and boiler blowdown wastewater, unless specifically included in the Pretreatment Standard) and the following conditions are met: a. The Industrial User, prior to City's finding, has consistently complied with all applicable Categorical Pretreatment Standards and requirements; b.
