Current through Register Vol. 42, No. 9, June 28, 2024
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.
(h) "Construction" means that the owner or
				operator has:
1. Begun, or caused to begin as
				part of a continuous on-site construction program:
(i) Any placement, assembly, or installation
				of facilities or equipment; or
(ii)
				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
