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 in sub. (2). The initial compliance period begins on the
				  applicable compliance date specified in s.
				  NR
				  465.41(4) and ends on the last day of
				  the 12th month following 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 that month plus the next 12 months. The initial compliance
				  demonstration includes the calculations according to sub. (2) and supporting
				  documentation showing that during the initial compliance period, you used no
				  coating with an organic HAP content that exceeded the applicable emission limit
				  in s.
				  NR
				  465.43(1), and that you used no
				  thinners or other additives, or cleaning materials that contained organic HAP
				  as determined according to sub. (2) (a).
(2) HOW DO I DEMONSTRATE INITIAL COMPLIANCE
				  WITH THE EMISSION LIMITS? You may use the compliant material option for any
				  individual coating operation, for any group of coating operations in the
				  affected source or for all the coating operations in the affected source. You
				  shall use either the emission rate without add-on controls option in s.
				  NR
				  465.43(2) (b) or the emission rate
				  with add-on controls option in s.
				  NR
				  465.43(2) (c) for any coating
				  operation in the affected source for which you do not use the compliant
				  material option. To demonstrate initial compliance using the compliant material
				  option, the coating operation or group of coating operations may not use any
				  coating with an organic HAP content that exceeds the applicable emission limits
				  in s.
				  NR
				  465.43(1) and may not use any thinner
				  or other additive, or cleaning material that contains organic HAP as determined
				  according to pars. (a) to (e). Any coating operation for which you use the
				  compliant material option is not required to meet the operating limits or work
				  practice standards required in s.
				  NR
				  465.43(3) and (4), respectively. You
				  shall conduct a separate initial compliance demonstration for each general use,
				  high performance, magnet wire, rubber-to-metal and extreme performance
				  fluoropolymer coating operation unless you are demonstrating compliance with a
				  predominant activity or facility-specific emission limit as provided in s.
				  NR
				  465.43(1) (c). If you are
				  demonstrating compliance with a predominant activity or facility-specific
				  emission limit, you shall demonstrate that all coating operations included in
				  the predominant activity determination or calculation of the facility-specific
				  emission limit comply with that limit. You shall meet all the requirements of
				  this subsection. You shall use the procedures in pars. (a) to (e) on each
				  coating, thinner, other additive and cleaning material in the condition it is
				  in when it is received from its manufacturer or supplier and prior to any
				  alteration. You do not need to redetermine the organic HAP content of coatings,
				  thinners, other additives and cleaning materials that are reclaimed on-site, or
				  reclaimed off-site if you have documentation showing that you received back the
				  exact same materials that were sent off-site, and reused in the coating
				  operation or operations for which you use the compliant material option,
				  provided these materials in their condition as received were demonstrated to
				  comply with the compliant material option.
(a)
Determine the mass fraction of
				  organic HAP for each material used.
You shall determine the mass
				  fraction of organic HAP for each coating, thinner, other additive and cleaning
				  material used during the compliance period by using one of the options in
				  subds. 1. to 5.
1. `Method 311.' You may use
				  Method 311 in 40 CFR part 63, Appendix A, incorporated by reference in s.
				  NR
				  484.04(25), for determining the mass
				  fraction of organic HAP. Use the procedures specified in subd. 1. a. and b.
				  when performing a Method 311 test.
a. Count
				  each organic HAP that is measured to be present at 0.1 % by mass or more for
				  Occupational Safety and Health Administration (OSHA)-defined carcinogens as
				  specified in
				  29 CFR
				  1910.1200(d)(4) and at 1.0 %
				  by mass or more for other compounds. Express the mass fraction of each organic
				  HAP you count as a value truncated to 4 places after the decimal point.
Note: For example, if toluene, which is not an OSHA
					 carcinogen, is measured to be 0.5% of the material by mass, you do not have to
					 count it.
b. Calculate the
				  total mass fraction of organic HAP in the test material by adding up the
				  individual organic HAP mass fractions and truncating the result to 3 places
				  after the decimal point.
