Current through Register Vol. 43, No. 1, October 31, 2024

Section 335-6-6-.02 - Definitions

Wherever used in this chapter, unless a different meaning clearly appears from the context or unless a different meaning is stated in a definition applicable to only a portion of this chapter, the following shall mean:

[NOTE: Due to the chronology of the adoption of the following definitions, a definition may not appear in alphabetical order. Please review the entire list before concluding that a term is not defined.]

(a) "Applicable standards and limitations" means all state, interstate, and federal standards and limitations to which a "discharge" or a related activity is subject under the FWPCA and AWPCA, including "effluent limitations," water quality standards, standards of performance, toxic effluent standards or prohibitions, "best management practices," and pretreatment standards under Sections 301, 302, 303, 304, 306, 307, 308, 403, and 405 of the FWPCA and their implementing regulations and the AWPCA and its implementing rules.

(b) "Application" means forms, and additional information that are required by Rule 335-6-6-.08 to be submitted when applying for an NPDES permit.

(c) "Average monthly discharge limitation" means the highest allowable average of "daily discharges" over a calendar month, calculated as the sum of all "daily discharges" measured during a calendar month divided by the number of "daily discharges" measured during that month (zero discharge days shall not be included in the number of "daily discharges" measured). When an EPA approved method is used by the permittee, a value of less than the Minimum Level (ML) shall be considered zero for purposes of calculating the average monthly discharge of the substance. For example, if a discharge is monitored on three days during a month and the results of testing for a substance on those three days are 1, 2, and less than the ML the average monthly discharge is equal to 1 + 2 + 0 divided by 3 which would equal 1.

(d) "Average weekly discharge limitation" means the highest allowable average of "daily discharges" over a calendar week, calculated as the sum of all "daily discharges" measured during a calendar week divided by the number of "daily discharges" measured during that week (zero discharge days shall not be included in the number of "daily discharges" measured). When an EPA approved method is used by the permittee, a value of less than the Minimum Level (ML) shall be considered zero for purposes of calculating the average weekly discharge of the substance. For example, if a discharge is monitored on three days during a week and the results of testing for a substance on those three days are 1, 2, and less than the ML, the average monthly discharge is equal to 1 + 2 + 0 divided by 3 which would equal 1.

(e) "ASMC" shall mean the Alabama Surface Mining Commission.

(f) "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, operating procedures, and practices to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

(g) "Bypass" means the intentional diversion of waste streams from any portion of a waste treatment facility.

(ggg) "Zone of initial dilution" or "ZID" means that area extending from the port openings of a high rate diffuser to the initial edge of the mixing zone where due to great turbulence a constant instream waste concentration (IWC) cannot be determined. For purposes of this definition a high rate diffuser is a submerged outfall in the form of a single pipe outlet or of multiport design giving rise to one or several submerged discharge jets designed to induce mixing between the effluent and receiving stream. The diffuser will protect against surface impingement and bottom attachment of the submerged jet(s) and in general a minimum exit velocity of ten feet per second shall be provided. The length of the ZID and thereby the distance to the initial edge of the mixing zone shall not exceed the more stringent of the following requirements:

1. Fifty times the discharge length scale (DLS) in any spatial direction, where the DLS is the square root of the cross-sectional area of any discharge outlet,

(hhh) Pesticide discharges to waters of the State from pesticide application means the discharges that result from the application of biological pesticides, and the application of chemical pesticides that leave a residue, from point sources to waters of the State. In the context of this definition of pesticide discharges to waters of the State from pesticide application, this does not include agricultural storm water discharges and return flows from irrigated agriculture, which are excluded by paragraphs 335-6-6-.03(1) (d) and (e).

(iii) Pesticide residue for the purpose of determining whether an NPDES permit is needed for discharges to waters of the State from pesticide application, means that portion of a pesticide application that is discharged from a point source to waters of the State and no longer provides pesticidal benefits. It also includes any degradates of the pesticide.
