(1) Act means the Clean Water Act formerly referred to as the Federal Water Pollution Control Act, 33 USC 1251 et seq. (see section 750-1.25 of this Subpart).

(2) Action level means, when used in a SPDES permit, a monitoring requirement characterized by a numerical value that, when exceeded, triggers additional permittee monitoring and department review to determine if numerical effluent limitations should be imposed.

(3) Administrative renewal means renewal of a SPDES permit in accordance with Part 621 of this Title, based on an abbreviated review of changes at the permitted facility.

(4) Administrator means the administrator of the EPA.

(5) Animal feeding operation (AFO) means a lot or facility (other than an aquatic animal production facility) where animals have been, are, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period, and the animal confinement areas do not sustain crops, vegetation, forage growth, or post-harvest residues in the normal growing season. Two or more animal feeding operations under common ownership are a single animal feeding operation if they physically adjoin each other, or if they use a common area or system for the disposal of wastes.

(7) Applicable water quality standards and effluent limitations means all State and Federal water quality standards and effluent limitations to which a discharge is subject under the act, or under State law, including but not limited to water quality standards, effluent limitations, best management practices, standards of performance, toxic effluent standards and prohibitions, pretreatment standards, and ocean discharge criteria.

(8) Approvable is defined as that which can be approved by the department, with only minimal revision. Minimal revision shall mean revised and resubmitted to the department within 60 days of notification by the department of the revisions that are necessary, unless otherwise defined by the applicable SPDES permit.

(9) Average means the arithmetic mean of pollutant parameter values for samples collected in a given period.

(10) Best available technology economically achievable (BAT) means effluent limits authorized under section 301(b)(2)(A) of the act, 40 CFR 122.44(a) and (e)(1) and (2), 40 CFR 125.3(2)(iii), 40 CFR 405 to 471 (see section 750-1.25 of this Subpart) and ECL 17-0801. BAT is technology-based effluent limitations guidelines established by the act as the most appropriate means available on a national basis for controlling the direct discharge of toxic and nonconventional pollutants to navigable waters. BAT effluent limitations guidelines, as established by EPA, represent the best existing performance of treatment technologies that are economically achievable within an industrial point source category or subcategory.

BCT is technology based effluent limitations guidelines for the discharge of conventional pollutants from existing industrial point sources including BOD5, TSS, fecal coliform, pH, oil and grease. The BCT is established by EPA using a two-part cost reasonableness test that compares the cost for an industry to reduce its pollutant discharge with the cost to a POTW for similar levels of reduction of a pollutant loading. The second test examines the cost-effectiveness of additional industrial treatment beyond BPT. EPA must find limits that are reasonable under both tests before establishing them as BCT.

(12) Best management practices (BMPs) means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of waters of the state. BMPs also include treatment requirements (if determined necessary by the permittee), operating procedures, and practices to control plant site runoff, spillage and leaks, sludge or waste disposal, or drainage from raw material storage.

The initial level of technology-based standards established by the CWA to control pollutants discharged to navigable waters, BPT effluent limitations guidelines are generally based on the average of the best existing performance by plants within an industrial category or subcategory. Because BPT has been supplanted by BAT and BCT in all other instances, BPT is only applied by EPA when proposed BCT limits fail the cost comparison with secondary treatment regulations for POTWs.

(14) Best professional judgement (BPJ) means effluent limits authorized under the Act section 402(a)(1)(B), 40 CFR 122.44(e)(1) and (2), 40 CFR 125.3(a)(2)(I)(B)-(v), 40 CFR 414.11(h), 40 CFR 501.15(b) (see section 750-1.25 of this Subpart) and ECL 17-0811. BPJ is the method used by permit writers to develop BAT or BCT limits or requirements on a case-by-case basis for pollutants and wastewaters not addressed by 40 CFR 405 to 471.

(15) Biological monitoring means the determination of the effects of the discharge of pollutants on aquatic life, including accumulation of pollutants in tissue, in receiving waters due to the discharge of pollutants by scientifically sound techniques and procedures, including sampling of organisms representative of appropriate levels of the food chain appropriate to the volume and the physical, chemical and biological characteristics of the effluent, at appropriate frequencies and locations.
