Section 218.926 Control Requirements

Every owner or operator of miscellaneous fabricated product manufacturing process emission unit subject to this Subpart shall comply with the requirements of subsection (a), (b) or (c) of this Section:

a) Emission capture and control techniques which achieve an overall reduction in uncontrolled VOM emissions of at least 81 percent from each emission unit; or

(Board Note: For the purpose of this provision, an emission unit is any part or activity at a source of a type that by itself is subject to control requirements in other Subparts of this Part or 40 CFR 60, incorporated by reference in Section 218.112, e.g., a coating line, a printing line, a process unit, a wastewater system, or other equipment, or is otherwise any part or activity at a source.)

b) For coating lines:

1) The daily-weighted average VOM content shall not exceed 0.42 kg VOM/1 (3.5 lbs VOM/gal) of coating as applied (minus water and any compounds which are specifically exempted from the definition of VOM) during any day. Owners and operators complying with this limitation are not required to comply with Section 218.301 of this Part; or

2) For application of coatings to leather at a source where the criteria of Section 218.290(a) are not met:

B) For application of coatings to specialty leather, the total VOM content of all coatings, including stains, as applied to a category of specialty leather, shall not exceed 38 lbs per 1000 square feet of such specialty leather produced, determined on a monthly basis:

Where:

C	=	The VOM contained in all coatings applied to a category of specialty leather in units of lbs/square feet;
E	=	The total VOM content of all coatings applied to the category of specialty leather during each month in units of lbs determined as the sum of the VOM content of each coating applied during the month to such leather;
A	=	The total area of the category of specialty leather produced in the month in units of square feet, determined as the sum of the area of each type of leather item produced during the month based on the number of such items produced and the area of such item, measured or established in accordance with procedures set in a federally enforceable permit; or

C) For application of coatings to leather, except for such coatings as are complying by means of Section 218.926(b)(2)(A) or (B) above, either

i) The VOM content of each coating shall not exceed 0.42 kg VOM/1 (3.5 lbs VOM/gal) of coating as applied (minus water and any compounds which are specifically exempted from the definition of VOM). Owners and operators complying with this limitation are not subject to Section 218.301 of this Part; or

ii) The daily-weighted average VOM content shall not exceed 0.42 Kg Vom/l (3.5 lbs Vom/gal) of coating as applied as provided in Section 218.916(b)(1) above; or
