Current through Register Vol. 42, No. 9, June 28, 2024
Whenever 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:

				applicable permit fees, and additional information required by this Chapter to
				be submitted when applying for a SID Permit.
(b) "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 having a detection limit
				lower than the permit limitation or when the EPA approved method having the
				lowest detection limit for a substance is used by the permittee, a value of
				less than detectable shall be considered zero for purposes of calculating the
				average monthly discharge of the substance.
(c) "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 having a detection limit lower than the
				permit limitation or when the EPA approved method having the lowest detection
				limit for a substance is used by the permittee, a value of less than detectable
				shall be considered zero for purposes of calculating the average weekly
				discharge of the substance.
