Current through June 24, 2024
(1) BY WHAT DATE MUST I CONDUCT THE INITIAL
				  COMPLIANCE DEMONSTRATION?. You shall complete the initial compliance
				  demonstration for the initial compliance period according to the requirements
				  of sub. (2). The initial compliance period begins on the applicable compliance
				  date specified in s.
				  NR
				  465.21(4) and ends on the last day of
				  the first full month after the compliance date. If the compliance date occurs
				  on any day other than the first day of a month, then the initial compliance
				  period extends through the end of that month plus the next month. The initial
				  compliance demonstration includes the calculations according to sub. (2) and
				  supporting documentation showing that the organic HAP emission rate for the
				  initial compliance period was equal to or less than the applicable emission
				  limit in s.
				  NR
				  465.23(1).
(2) HOW DO I DEMONSTRATE INITIAL COMPLIANCE
				  WITH THE EMISSION LIMITATIONS?. You may use the emission rate without add-on
				  controls option for any individual coating operation, for any group of coating
				  operations in the affected source, or for all of the coating operations in the
				  affected source. You shall use either the compliant material option or the
				  emission rate with add-on controls option for any coating operation or
				  operations in the affected source for which you do not use this option. To
				  demonstrate initial compliance using the emission rate without add-on controls
				  option, the coating operation or operations shall meet the applicable emission
				  limit in s.
				  NR
				  465.23(1) but not the operating
				  limits or work practice standards in s.
				  NR 465.23(3) and
				  (4), respectively, during the initial
				  compliance period. When calculating the organic HAP emission rate according to
				  this subsection, you may not include any coatings, thinners or cleaning
				  materials used on coating operations for which you use the compliant material
				  option or the emission rate with add-on controls option. You do not need to
				  redetermine the mass of organic HAP in coatings, thinners or cleaning materials
				  that have been reclaimed onsite and reused in the coating operation or
				  operations for which you use the emission rate without add-on controls option.
				  You shall meet all of the following requirements to demonstrate initial
				  compliance with the applicable emission limit in s.
				  NR
				  465.23(1) for the coating operation
				  or operations:
(a) Determine the mass fraction
				  of organic HAP for each coating, thinner and cleaning material used during the
				  compliance period according to the requirements in s.
				  NR
				  465.26(2) (a).
(b) Determine the volume fraction of coating
				  solids for each coating used during the compliance period according to the
				  requirements in s.
				  NR
				  465.26(2) (b).
(c) Determine the density of each coating,
				  thinner and cleaning material used during the compliance period according to
				  the requirements in s.
				  NR
				  465.26(2) (c).
(d) Determine the volume (liters) of each
				  coating, thinner and cleaning material used during the compliance period by
				  measurement or usage records.

1. Calculate the mass of organic HAP
				  emissions during the compliance period using the following equations and the
				  procedures in subd. 2. if applicable:

Rw is the total mass of organic HAP
					 in waste materials sent or designated for shipment to a hazardous waste TSDF
					 for treatment or disposal during the compliance period, kg, determined
					 according to subd. 2. You may assign a value of zero to Rw if you do not wish
					 to use this allowance

				  sent or designated for shipment to a hazardous waste TSDF in the calculation of
				  the mass of organic HAP emissions using Equation 1, you shall determine it
				  according to the following procedures:
a. You
				  may include in the determination of organic HAP in waste materials only the
				  waste materials that are generated by coating operations for which you use
				  Equation 1 in subd. 1. and that will be treated or disposed of by a facility
				  that is regulated as a TSDF under 40 CFR part 262, 264, 265, or 266. The TSDF
				  may be either off-site or on-site. You may not include in the determination the
				  organic HAP contained in wastewater.
b. Determine either the amount of waste
				  materials sent to a TSDF during the compliance period or the amount collected
				  and stored during the compliance period and designated for future transport to
				  a TSDF. You may not include in your determination any waste materials sent to a
				  TSDF during a compliance period if you have already included them in the amount
				  collected and stored during that compliance period or a previous compliance
				  period.
c. Determine the total mass
				  of organic HAP contained in the waste materials specified in subd. 2.

d. Document your methodology to
				  determine the amount of waste materials and the total mass of organic HAP they
				  contain, as required in s.

				  this information, they may be used as part of the documentation of the amount
				  of waste materials and mass of organic HAP contained in them.

				  volume of coating solids used, liters, which is the combined volume of coating
				  solids for all of the coatings used during the compliance period, using the

				  that the organic HAP emission rate for the initial compliance period is less
				  than or equal to the applicable emission limit in s.
				  NR
				  465.23(1). You shall keep all records
				  as required by s.

				  and (4). As part of the notification of
				  compliance status required by s.

				  465.25(1), you shall identify the
				  coating operation or operations for which you used the emission rate without
				  add-on controls option and submit a statement that the coating operation was,
				  or operations were, in compliance with the emission limitations during the
				  initial compliance period because the organic HAP emission rate was less than
				  or equal to the applicable emission limit in s.
