Domestic Wastewater Pretreatment Program Definitions

The following definitions are taken from Rule 62-625.200, F.A.C, and are applicable to Florida's pretreatment program. The meaning of any term not defined below shall be taken from definitions in other rules of the Department, unless the context clearly indicates otherwise.

  1. Bypass means the intentional diversion of wastewater streams from any portion of an industrial user's treatment facility. [62-625.200(1), F.A.C.]
  2. Best Management Practices (BMP) mean schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to implement the prohibitions listed in subsections 62-625.400(1)(a) and (2), F.A.C. BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, industrial sludge or waste disposal, or drainage from raw materials storage. [62-625.200(2), F.A.C.]
  3. Categorical Industrial User (CIU) means an industrial user subject to categorical pretreatment standards under Rule 62-625.410, F.A.C., including 40 CFR Chapter I, Subchapter N, Parts 405-471, as of July 1, 2009, hereby adopted and incorporated by reference. [62-625.200(3), F.A.C.]
  4. Consistent Removal means the average of the lowest 50 percent of the removal measured in accordance with subsection 62-625.420(2), F.A.C. [62-625.200(4)]
  5. Control Authority (CA) means any public utility that administers a pretreatment program that has been approved by the approval authority in accordance with the requirements of Rule 62-625.510, F.A.C. In cases where categorical or significant noncategorical industrial users discharge to domestic WWFs that are not included in an approved pretreatment program, the Department shall function as the control authority until an approved pretreatment program has been established by the public utility. [62-625.200(5)]
  6. Discharge means the introduction of pollutants into a WWF from any nondomestic source regulated under Chapter 403, F.S. [62-625.200(6)]
  7. Grab Sample means an individual, discrete sample collected at a specific time. A grab sample includes all sub samples or aliquots (e.g. individual containers for specific analytes or analyte groups), sample fractions (e.g. total and filtered samples), and all applicable field quality control samples (e.g. field sample duplicates or split samples) collected at the same locations within a time not exceeding 15 minutes. [62-625.200(7)]
  8. Industrial User (IU) means a source of discharge. [62-625.200(8)]
  9. Interference means a discharge which, alone or in conjunction with a discharge or discharges from other sources, both:
    1. Inhibits or disrupts the WWF, its treatment processes or operations, or its domestic wastewater residuals processes, use or disposal; and
    2. Is a cause of a violation of any requirement of the WWF's permit (including an increase in the magnitude or duration of a violation) or prevents use or disposal of domestic wastewater residuals in compliance with local regulations or rules of the Department and Chapter 403, F.S. [62-625.200(9)]
  10. Instantaneous limit means the maximum concentration of a pollutant allowed to be discharged at any time, determined from the analysis of any discrete or composited sample collected, independent of the industrial flow rate and the duration of the sampling event. [62-625.200(10)]
  11. Maximum Allowable Industrial Loading means the total mass of a pollutant that all industrial users and other controlled sources may discharge without causing pass through or interference. [62-625.200(11)]
  12. Method Detection Limit (MDL) means an estimate of the minimum amount of a substance that an analyte process can reliably detect. A MDL is analyte- and matrix-specific and is laboratory dependent. [62-625.200(12)]
  13. New Source means:
    1. Any building, structure, facility or installation from which there is or may be a discharge, the construction of which commenced after the publication of proposed pretreatment standards under section 307(c) of the CWA which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
      1. The building, structure, facility or installation is constructed at a site at which no other source is located,
      2. The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source, or
      3. 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 shall 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 (a)2. or (a)3. above but otherwise alters, replaces, or adds to existing process or production equipment; or
    3. Construction of a new source, as defined in this chapter, has commenced if the owner or operator has:
      1. Begun, or caused to begin as part of a continuous on-site 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
      2. Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering, and design studies do not constitute a contractual obligation under Chapter 62-625, F.A.C. [62-625.200(13)]
  14. Non-significant categorical industrial user (NSCIU) means an industrial user that discharges 100 gallons per day (gpd) or less of total categorical wastewater (excluding sanitary, non-contact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and:
    1. Has consistently complied with all applicable categorical pretreatment standards and requirements;
    2. Annually submits the certification statement required in subsection 62-625.600(17), F.A.C., together with any additional information necessary to support the certification statement; and
    3. Never discharges any untreated categorical process wastewater. [62-625.200(14)]
  15. Pass Through means a discharge which exits the WWF into waters of the State or of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the WWF's permit (including an increase in the magnitude or duration of a violation). [62-625.200(15)]
  16. Permit means a permit issued to a WWF in accordance with Chapter 62-620, F.A.C. [62-625.200(16)]
  17. Pretreatment means 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 discharging or otherwise introducing such pollutants into a WWF.

    3. The control authority (except where the Department is acting as the control authority) may determine that an industrial user subject to categorical pretreatment standards under Rule 62-625.410, F.A.C., including 40 CFR Chapter I, Subchapter N, Parts 405 through 471, is a non-significant categorical industrial user.
    4. Upon a finding that an industrial user meeting the criteria in paragraph (b) above has no reasonable potential for adversely affecting the WWF’s operation or for violating any pretreatment standard or requirement, the control authority may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with paragraph 62-625.500(2)(e), F.A.C., determine that such industrial user is not a significant industrial user.
