Current through Vol. 24-12, July 15, 2024
Rule 621a.
(1) A
				person shall not cause or allow the emission of any volatile organic compound
				from an existing metallic surface coating line at a facility located in the
				2015 ozone nonattainment areas in excess of the applicable emission rates
				provided in subrule (3) of this rule.
(2) This rule does not apply to the
				following:
(a) Except as provided in subrule
				(5) of this rule, metallic surface coating lines that are within a stationary
				source and have a combined actual emission rate of volatile organic compounds,
				including related cleaning activities, of less than 15 pounds per calendar day
				before consideration of controls. If the combined actual emission rate equals
				or is more than 15 pounds per calendar day for a subsequent day, then this rule
				permanently applies to these coating lines.
(b) Metallic surface coating lines that meet
				any of the following processes:
(i) The
				portion of a metallic surface coating process that is addressed in
				R 336.1610,
				R 336.1610a,
				R 336.1620,
				R 336.1620a,
				R 336.1635,
				R 336.1636,
				R 336.1637,
				R 336.1638, and
				R 336.1639.
(ii) Coating of a part consisting of both
				metallic and nonmetallic components if a demonstration is made to the
				satisfaction of the department, under
				R 336.1602(2), that
				the limits of this rule cannot be met due to the presence of the nonmetallic
				component. In this case, and if the nonmetallic component of the part is
				plastic and used as an automobile, truck, or business machine plastic part,
				R 336.1632 applies to the coating of
				the part, as applicable.
(iii)
				Aerosol coatings.
(iv)
				Architectural coatings, and automobile refinish coatings that are used for
				architectural coating or automobile refinish coating purposes as defined by
				their respective national volatile organic compound rules.
(v) Coatings that are applied to test panels
				and coupons as part of research and development, quality control, or
				performance testing activities at paint research or manufacturing
				facilities.
(vi) Customized top
				coating of less than 35 automobiles or trucks, or both, per calendar
				day.
(vii) Coating of the exterior
				of airplanes when the part to be coated has already been assembled on the
				airplane.
(viii) Coating of the
				exterior of marine vessels when the part to be coated has already been
				assembled on the marine vessel.
(ix) Coatings used on a non-production
				basis.
(x) Rubber to metal
				bonding.
(c) The
				following metal parts coating processes are exempt from subrule (3) of this
				rule:
(i) Stencil coatings.
(ii) Safety-indicating coatings.
(iii) Solid-film lubricants.
(iv) Electric-insulating and
				thermal-conducting coatings.
(v)
				Magnetic data storage disk coatings.
(vi) Plastic extruded onto metal parts to
				form a coating.
(d) The
				coating of bodies or body parts for new heavier vehicles at an automobile and
				light-duty truck assembly facility or a heavier vehicle assembly facility where
				the person responsible elects to comply with the provisions of
				R 336.1610a under the
				classification of automobile and light-duty truck coating lines.
(e) The application methods required by
				subrule (3)(b) of this rule do not apply to airbrush operations using 5 gallons
				or less per year of coating.
(f) A
				person subject to this rule may exclude low-use coatings that have a combined
				total less than 55 gallons per rolling 12-month period at a stationary source
				from the provisions of this rule, except for subrule (5) of this
				rule.
