ant control technology (BCT). Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best conventional pollutant control technology (BCT): The limitations shall be the same as those specified for conventional pollutants (which are defined in 40 CFR 401.16) in $ 430.12 of this subpart for the best practicable control technology currently available (BPT).

representing the degree of effluent reduction attainable by the application of the best available technology economically achievable

(BAT). Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart where chlorophenolic-containing biocides are used must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT). Non-continuous dischargers shall not be subject to the maximum day mass limitations in kg/kkg (lb/1000 lb) but shall be subject to concentration limitations. Concentration limitations are only applicable to non-continuous dischargers. Permittees not using chlorophenolic-containing biocides must certify to the permit-issuing authority that they are not using these biocides:

Subpart B-Bleached Papergrade

Kraft and Soda Subcategory $ 430.20 Applicability; description of

the bleached papergrade kraft and

soda subcategory. The provisions of this subpart apply to discharges resulting from: The production of market pulp at bleached kraft mills; the integrated production of paperboard, coarse paper, and tissue paper at bleached kraft mills; the integrated production of pulp and fine papers at bleached kraft mills; and the integrated production of pulp and paper at soda mills.

the permitting authority as long as the mill signs the correspondence in accordance with 40 CFR 122.22.

(d) Existing effluent quality means the level at which the pollutants identified in $430.24(a)(1) are present in the effluent of a mill "enrolled" in the “Voluntary Advanced Technology Incentives Program."

(e) Kappa number is a measure of the lignin content in unbleached pulp, determined after pulping and prior to bleaching.

(f) Voluntary Advanced Technology Incentives Program is the program established under $ 430.24(b) (for existing direct dischargers) and § 430.25(c) (for new direct dischargers) whereby participating mills agree to accept enforceable effluent limitations and conditions in their NPDES permits that are more stringent than the “baseline BAT limitations or NSPS” that would otherwise apply,

exchange for regulatory and enforcement-related rewards and incentives.

$ 430.21 Specialized definitions.

(a) The general definitions, abbreviations, and methods of analysis set forth in 40 CFR part 401 and $ 430.01 of this part apply to this subpart.

(b) Baseline BAT limitations or NSPS means the BAT limitations specified in § 430.24(a) (1) or (2), as applicable, and the NSPS specified in $430.25(b) (1) or (2), as applicable, that apply to any direct discharger that is not "enrolled": in the “Voluntary Advanced Technology Incentives Program.”

(c) Enroll means to notify the permitting authority that a mill intends to participate in the “Voluntary Advanced Technology Incentives Program.” A mill can enroll by indicating its intention to participate in the program either as part of its application for a National Pollutant Discharge Elimination System (NPDES) permit, or through separate correspondence to
