Current through August 26, 2024
(1) The effluent
limitations and standards set forth in this chapter shall be used in accordance
with this section to establish the quantity or quality of pollutants or
pollutant properties which may be discharged by a point source subject to the
provisions of this chapter, except as:
(a)
They may be modified in accordance with subch. IV of ch. NR 220,
(b) They may be superseded by more stringent
limitations and standards necessary to achieve water quality standards or meet
other legal requirements, or
(c)
They may be supplemented or superseded by standards or prohibitions for toxic
pollutants or by additional limitations for other pollutants required to
achieve water quality.
(2) Except as provided in subs. (5) and (6),
the quantities of suspended solids and BOD which may be discharged by a
facility subject to the provisions of this chapter shall not exceed:
(a) Daily maximum and daily average
limitations determined for discharges resulting from processing in each of
subcategories (1) through (5);
(b)
Daily maximum, daily average, and annual limitations determined for discharges
resulting from the processing of each commodity or product in subcategories (6)
through (8) in the case of facilities which discharge process waste waters
continuously or intermittently during the processing season; or
(c) Annual limitations determined for
discharge resulting from the processing of each commodity or product in
subcategories (6) through (8) in the case of facilities employing long term
waste stabilization where all or a portion of the process waste water discharge
is stored for the entire processing season and released at a controlled rate
with department approval.
(3) The limitations described in sub. (2)
shall be based on production and determined by multiplying the appropriate
quantity of production for each commodity by the corresponding effluent
limitation or standard set forth in table 1 or 2 of this chapter.
(a) The production shall be in terms of
product for commodities other than soup in subcategory (8) and in terms of raw
material processed for other commodities.
(b) The production used to determine daily
maximum and daily average limitations shall be the production for each
commodity processed during the peak 30 consecutive day production period of the
year for the facility.
(c) The
production used to determine annual limitations shall be the production for
each commodity during the entire processing season or calendar year.
(4) Discharge limitations for
facilities subject to limitations covering more than one commodity or
subcategory shall be the sum of limitations determined for the individual
commodities or subcategories determined in accordance with subs. (2) and
(3).
(5) The effluent limitations
and standards set forth in this chapter for subcategories (6) through (8) are
applicable only to large and medium size point source facilities or
plants.
(6) For the purposes of ss.
NR 225.10 and 225.11 the effluent limitations and
standards of this chapter are not applicable to:
(a) Facilities which are single commodity
100% canned corn processing plants, or
(b) Facilities which are multi-commodity
frozen vegetable processing plants with total annual raw material production
less than 7,264 kkg (8,000 tons) per year.
