NR 460 to
469, an affected source at any
major source or any area source at a performance track member facility, as
defined in s.
NR 460.02(37g), which is subject to
regular periodic reporting under any relevant standard, may submit periodic
reports at an interval that is twice the length of the regular period specified
in the applicable standards provided, that for sources subject to permits under
ch. NR 406 or 407, no interval for any report of the results of any required
monitoring may be less frequent than once in every 6 months.
(2) Notwithstanding any other requirements in
40 CFR part 63 or chs.
NR 460 to
469, the modifications of
reporting requirements in sub. (3) apply to any major source at a performance
track member facility, as defined in s.
NR 460.02(37g), which is subject to
requirements under any relevant standard and which has done all of the
following:
(a) Reduced its total HAP
emissions to less than 25 tons per year.
(b) Reduced its emissions of each individual
HAP to less than 10 tons per year.
(c) Reduced emissions of all HAPs covered by
each MACT standard to at least the level required for full compliance with the
applicable emission standard.
(3) For affected sources at any area source
at a performance track member facility, as defined in s.
NR 460.02(37g), that meet the
requirements of sub. (2) (c), or for affected sources at any major source that
meet the requirements of sub. (2):
(a) If the
emission standard to which the affected source is subject is based on add-on
control technology, and the affected source complies by using add-on control
technology, all required reporting elements in the periodic report may be met
through an annual certification that the affected source is meeting the
emission standard by continuing to use that control technology. The affected
source shall continue to meet all relevant monitoring and recordkeeping
requirements. The compliance certification shall meet the requirements
delineated in Clean Air Act section 114 (a) (3).
(b) If the emission standard to which the
affected source is subject is based on add-on control technology, and the
affected source complies by using pollution prevention, all required reporting
elements in the periodic report may be met through an annual certification that
the affected source is continuing to use pollution prevention to reduce HAP
emissions to levels at or below those required by the applicable emission
standard. The affected source shall maintain records of all calculations that
demonstrate the level of HAP emissions required by the emission standard as
well as the level of HAP emissions achieved by the affected source. The
affected source shall continue to meet all relevant monitoring and
recordkeeping requirements. The compliance certification shall meet the
requirements delineated in Clean Air Act section 114 (a) (3).
(c) If the emission standard to which the
affected source is subject is based on pollution prevention, and the affected
source complies by using pollution prevention and reduces emissions by an
additional 50% or greater than required by the applicable emission standard,
all required reporting elements in the periodic report may be met through an
annual certification that the affected source is continuing to use pollution
prevention to reduce HAP emissions by an additional 50% or greater than
required by the applicable emission standard. The affected source shall
maintain records of all calculations that demonstrate the level of HAP
emissions required by the emission standard as well as the level of HAP
emissions achieved by the affected source. The affected source shall continue
to meet all relevant monitoring and recordkeeping requirements. The compliance
certification shall meet the requirements delineated in Clean Air Act section
114 (a) (3).
(d) Notwithstanding
the provisions of pars. (a) to (c), for sources subject to permits under ch. NR
406 or 407, the results of any required monitoring and recordkeeping shall be
reported not less frequently than once in every 6 months.
