CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 437--THE CENTRALIZED WASTE TREATMENT POINT SOURCE CATEGORY--Table of Contents
Subpart D--Multiple Wastestreams
Sec. 437.42 Effluent limitations attainable by the application of the best practicable control technology currently available (BPT).
(a) Except as provided in 40 CFR 125.30 through 125.32 or
Sec. 437.40(b), any existing facility subject to this subpart which
combines treated or untreated wastes from subparts A, B, or C of this
part may be subject to Multiple Wastestream Subcategory effluent
limitations representing the application of BPT set forth in paragraphs
(b), (c), (d), or (e) of this section if the discharger agrees to the
following conditions in its NPDES permit:
(1) The discharger will meet the applicable Multiple Wastestream
Subcategory limitations set forth in (b), (c), (d) or (e);
(2) The discharger will notify its NPDES permit writer at the time
of renewal or modification of its permit, of its desire to be subject to
the Multiple Waste Subcategory by submitting to the NPDES permit writer
an initial certification statement as described in Sec. 437.41(a);
(3) The discharger will submit to its NPDES permitting authority a
periodic certification statement as described in Sec. 437.41(b) once a
year; and
(4) The discharger will maintain at the office of the facility and
make available for inspection the on-site compliance paperwork as
described in Sec. 437.41(c).
(b) Combined waste receipts from subparts A, B, and C of this part.
(1) As provided in Sec. 437.42(a), any existing point source subject to
this paragraph must achieve the following effluent limitations
representing the application of BPT:
