enrolled in the Voluntary Advanced Technology Incentives Program:
(1) Stage 1 Limitations: Numeric limitations that are equivalent to
the discharger's existing effluent quality or the discharger's current
effluent limitations established under CWA section 301(b)(2), whichever
are more stringent, for the pollutants identified in paragraph (a)(1)
of this section (with the exception of COD). For AOX, the permitting
authority must determine existing effluent quality for each fiber line
enrolled in the Voluntary Advanced Technology Incentives Program at the
end of the pipe based on loadings attributable to that fiber line. For
the remaining pollutants, with the exception of COD, the permitting
authority must determine existing effluent quality for each fiber line
enrolled in the Voluntary Advanced Technology Incentives Program at the
point where the wastewater containing those pollutants leaves the
bleach plant. These limitations must be recalculated each time the
NPDES permit of a discharger enrolled in the Voluntary Advanced
Technology Incentives Program is reissued, up to:
(i) April 15, 2004 for all pollutants in paragraph (a)(1) of this
section except AOX; and
(ii) The date specified in paragraph (b)(4)(ii) of this section for
achieving the applicable AOX limitation specified in paragraph
(b)(4)(i).
[[Page 18654]]
(2) Best Professional Judgment Milestones: Narrative or numeric
limitations and/or special permit conditions, as appropriate,
established by the permitting authority on the basis of his or her best
professional judgment that reflect reasonable interim milestones toward
achievement of the effluent limitations specified in paragraphs (b)(3)
and (b)(4) of this section, as applicable.
(3) Six-year Milestones: By April 15, 2004 all dischargers enrolled
in the Voluntary Advanced Technology Incentives Program must achieve
the following:
(i) The effluent limitations specified in paragraph (a)(1) of this
section, except that, with respect to AOX, dischargers subject to Tier
I effluent limitations specified in paragraph (b)(4)(i) of this section

authorities may do so as appropriate.
(b) The following pretreatment standards apply to all new source
indirect dischargers, regardless of when they commenced discharge, in
accordance with the previous subcategorization scheme. An indirect
discharger is not required to meet these pretreatment standards if it
certifies to the pretreatment control authority that it is not using
these compounds as biocides. In cases when POTWs find it necessary to
impose mass-based effluent limitations, equivalent mass limitations are
provided as guidance:
