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
				  465.31(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 the end of that month plus the next 12 months. You shall
				  determine the mass of organic HAP emissions and mass of coating solids used
				  each month and then calculate an organic HAP emission rate at the end of the
				  initial compliance period. The initial compliance demonstration includes the
				  calculations according to sub. (2) and supporting documentation showing that
				  during the initial compliance period the organic HAP emission rate was equal to
				  or less than the applicable emission limit in s.
				  NR
				  465.33(1).
(2) HOW DO I DEMONSTRATE INITIAL COMPLIANCE
				  WITH THE EMISSION LIMITS? 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 the coating operations in the
				  affected source. You shall use either the compliant material option in s.
				  NR
				  465.33(2) (a) or the emission rate
				  with add-on controls option in s.
				  NR
				  465.33(2) (c) for any coating
				  operation in the affected source for which you do not use the emission rate
				  without add-on controls option. To demonstrate initial compliance using the
				  emission rate without add-on controls option, the coating operation or group of
				  coating operations shall meet the applicable emission limit in s.
				  NR
				  465.33(1), but is not required to
				  meet the operating limits or work practice standards in s.
				  NR
				  465.33(3) and (4). You shall conduct
				  a separate initial compliance demonstration for each general use, TPO,
				  automotive lamp and assembled on-road vehicle coating operation, unless you are
				  demonstrating compliance with a predominant activity or facility-specific
				  emission limit as provided in s.
				  NR
				  465.33(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. When calculating the organic HAP emission rate according to
				  this subsection, do not include any coatings, thinners or other additives, or
				  cleaning materials used on coating operations for which you use the compliant
				  material option in s.
				  NR
				  465.33(2) (a) or the emission rate
				  with add-on controls option in s.
				  NR
				  465.33(2) (c). You do not need to
				  redetermine the mass of organic HAP in coatings, thinners or other additives,
				  or cleaning materials that have been 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 emission rate without add-on controls option.
				  If you use coatings, thinners or other additives, or cleaning materials that
				  have been reclaimed on-site, the amount of each used in a month may be reduced
				  by the amount of each that is reclaimed. That is, the amount used may be
				  calculated as the amount consumed to account for materials that are reclaimed.
(a)
Determine the mass fraction of
				  organic HAP for each material.
Determine the mass fraction of organic
				  HAP for each coating, thinner and other additive, and cleaning material used
				  during each month according to the requirements in s.
				  NR
				  465.36(2) (a).
(b)
Determine the mass fraction of
				  coating solids.
Determine the mass fraction of coating solids, kg (lb)
				  of coating solids per kg (lb) of coating, for each coating used during each
				  month according to the requirements in s.
				  NR
				  465.36(2) (b).
(c)
Determine the density of each
				  material.
Determine the density of each liquid coating, thinner, other
				  additive and cleaning material used during each month from test results using
				  ASTM D1475-98(2003), "Standard Test Method for Density of Liquid Coatings,
				  Inks, and Related Products", incorporated by reference in s.
				  NR
				  484.10(22), information from the
				  supplier or manufacturer of the material, or reference sources providing
				  density or specific gravity data for pure materials. If there is disagreement
				  between ASTM D1475-98 (2003) and other information sources, the test results
				  will take precedence unless, after consultation, you demonstrate to the
				  satisfaction of the department that the formulation data are correct. If you
				  purchase materials or monitor consumption by weight instead of volume, you do
				  not need to determine material density. Instead, you may use the material
				  weight in place of the combined terms for density and volume in Equations 1A,
				  1B, 1C and 2 of this subsection.
(d)
Determine the volume of each
				  material used.
Determine the volume, in liters or gallons, of each
				  coating, thinner and other additive, and cleaning material used during each
				  month by measurement or usage records. If you purchase materials or monitor
				  consumption by weight instead of volume, you do not need to determine the
				  volume of each material used. Instead, you may use the material weight in place
				  of the combined terms for density and volume in Equations 1A, 1B, 1C and 2 of
				  this subsection.
(e)
Calculate the mass of organic HAP emissions.

				  combined mass of organic HAP contained in all coatings, thinners and other
				  additives, and cleaning materials used during each month minus the organic HAP
