Domestic Wastewater Pretreatment Program Definitions


The following definitions are taken from Chapter 62-625, F.A.C. (125K), and are primarily applicable to Florida's pretreatment program.

62-625.200 Definitions. Terms used in this chapter shall have the following meaning specified below. 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) "Approval Authority" means the Department of Environmental Protection or its successor agencies.

(2) "Bypass" means the intentional diversion of wastewater streams from any portion of an industrial user's treatment facility.

(3) "Consistent Removal" means the average of the lowest 50 percent of the removal measured in accordance with Rule 62-625.420(2), F.A.C.

(4) "Control Authority" 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.

(5) "Discharge" means the introduction of pollutants into a WWF from any nondomestic source regulated under Chapter 403, F.S.

(6) "Industrial User" means a source of discharge.

(7) "Interference" means a discharge which, alone or in conjunction with a discharge or discharges from other sources, both:

(a) Inhibits or disrupts the WWF, its treatment processes or operations, or its domestic wastewater residuals processes, use or disposal;

(b) 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.

(8) "Measurement" refers to the ability of the analytical method or protocol to quantify, as well as identify, the presence of the substance in question.

(9) "New Source" means:

(a) 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;

(b) 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

(c) 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.

a. Any placement, assembly, or installation of facilities or equipment.

b. 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.

(10) "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).

(11) "Permit" means a permit, including a No Discharge (ND) permit, issued to a WWF in accordance with Chapter 62-620, F.A.C.

(12) "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. The reduction or alteration may be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by Rule 62-625.410(5), F.A.C. Appropriate pretreatment technology includes control equipment, such as equalization tanks or facilities for protection against surges or slug discharges that might interfere with or otherwise be incompatible with the WWF. However, where wastewater from a regulated process is mixed in an equalization facility with unregulated wastewater or with wastewater from another regulated process, the effluent from the equalization facility must meet an adjusted pretreatment limit calculated in accordance with Rule 62-625.410(6), F.A.C.

(13) "Pretreatment Program" means a program administered by a public utility that meets the criteria established in Rule 62-625.500, F.A.C.

(14) "Pretreatment Requirement" means any substantive or procedural requirement related to pretreatment, other than a pretreatment standard, imposed on an industrial user.

(15) "Pretreatment Standard" means any regulation containing pollutant discharge limits promulgated by the Department under Chapter 403, F.S., which applies to industrial users. This term includes prohibitive discharge limits established in Rule 62-625.400, F.A.C.

(16) "Public Utility" means any state, county or municipality owning, managing, controlling or operating a domestic WWF, or proposing to construct a domestic WWF that provides or proposes to provide wastewater service.

(17) "Removal" means a reduction in the amount of a pollutant in the WWF's effluent or alteration of the nature of a pollutant during treatment at the WWF. The reduction or alteration can be obtained by physical, chemical or biological means and may be the result of specifically designed WWF capabilities or may be incidental to the operation of the treatment system. Removal as used in this chapter shall not mean dilution of a pollutant in the WWF.

(18) "Responsible Corporate Officer" means:

(a) A president, secretary, treasurer, vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy- or decision-making functions for the corporation; or

(b) The manager of one or more manufacturing, production, or operation facilities employing more than 250 persons or having gross annual sales or expenditures exceeding $25 million (in second-quarter 1980 dollars), if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.

(19) "Severe Property Damage" means substantial physical damage to property, damage to an industrial user's treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.

(20) "Significant Industrial User" means, except as provided in (c) below, the following:

(a) All industrial users subject to categorical pretreatment standards under Rule 62-625.410, F.A.C., and 40 CFR Chapter I, Subchapter N which has been adopted by reference in Chapter 62-660, F.A.C.; and

(b) Any other industrial user that discharges an average of 25,000 gallons per day or more of process wastewater to the WWF (excluding domestic wastewater, noncontact cooling and boiler blowdown wastewater); contributes a process waste stream which makes up 5 percent or more of the average dry weather hydraulic or organic capacity of the treatment plant; or is designated as such by the control authority on the basis that the industrial user has a reasonable potential for adversely affecting the WWF's operation or for violating any pretreatment standard or requirement in accordance with Rule 62-625.500(2)(e), F.A.C.

(c) Upon a finding that an industrial user meeting the criteria in (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 Rule 62-625.500(2)(e), F.A.C., determine that such industrial user is not a significant industrial user.

(21) "Slug Discharge" means any discharge of a nonroutine, episodic nature.

(22) "Treatment Plant" means that portion of a WWF which is designed to provide treatment (including recycling and reclamation) of domestic and industrial wastewater.

(23) "Upset" means an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards because of factors beyond the reasonable control of the industrial user.

(24) "Wastewater Facility" or "WWF" means any or all of the following: the collection/transmission system, the treatment plant, and the reuse or disposal system.

(25) "Water Management Division Director" means one of the Directors of the Water Management Divisions within the Regional offices of the EPA or this person's delegated representative.
