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
				  465.41(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 the end of that month plus the next 12 months. You shall
				  determine the mass of organic HAP emissions and volume 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
				  465.43(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
				  465.43(2) (a) 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 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
				  465.43(1), but is not required to
				  meet the operating limits or work practice standards in s.
				  NR
				  465.43(3) and (4). You shall conduct
				  a separate initial compliance demonstration for each general use, 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. When calculating the organic HAP emission rate according to
				  pars. (a) to (h), do not include any coatings, thinners, other additives or
				  cleaning materials used on coating operations for which you use the compliant
				  material option specified in s.
				  NR
				  465.43(2) (a) or the emission rate
				  with add-on controls option specified in s.
				  NR
				  465.43(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.
(a)
Determine the mass fraction of organic HAP for each material.
Determine the mass fraction of organic HAP for each coating, thinner, other
				  additive and cleaning material used during each month according to the
				  requirements in s.
				  NR
				  465.46(2) (a).
(b)
Determine the volume fraction of
				  coating solids.
Determine the volume fraction of coating solids, in
				  liters (gallons) of coating solids per liter (gallon) of coating, for each
				  coating used during each month according to the requirements in s.
				  NR
				  465.46(2) (b).
(c)
Determine the density of each
				  material.
Determine the density of each liquid coating, thinner or
				  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 you are including
				  powder coatings in the compliance determination, determine the density of
				  powder coatings, using ASTM D5965-02 "Standard Test Methods for Specific
				  Gravity of Coating Powders", incorporated by reference in s.
				  NR
				  484.10(55i), or information from the
				  supplier. If there is disagreement between ASTM Method D1475-98 (2003) or ASTM
				  Method D5965-02 test results 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 (gallons) of each
				  coating, thinner, 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 and 1C of this
				  subsection.
