Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 115 - CONTROL OF AIR POLLUTION FROM VOLATILE ORGANIC › Subchapter E - SOLVENT-USING PROCESSES › Division 2 - SURFACE COATING PROCESSES › Section 115.421 - Emission Specifications

Current through Reg. 49, No. 28; July 12, 2024
The owner or operator of the surface coating processes
						specified in §
											115.420(a)
						of this title (relating to Applicability and Definitions) shall not cause,
						suffer, allow, or permit volatile organic compound (VOC) emissions to exceed
						the specified emission limits in paragraphs (1) - (16) of this subsection.
						These limitations are based on the daily weighted average of all coatings
						delivered to each coating line, except for those in paragraph (9) of this
						subsection which are based on paneling surface area, and those in paragraph
						(15) of this subsection which, if using an averaging approach, must use one of
						the daily averaging equations within that paragraph. The owner or operator of a
						surface coating operation subject to paragraph (10) of the subsection may
						choose to comply by using the monthly weighted average option as defined in
						§
											115.420(c)(1)(YY)
						of this title.
(1) Large appliance
					 coating. VOC emissions from the application, flashoff, and oven areas during
					 the coating of large appliances (prime and topcoat, or single coat) must not
					 exceed 2.8 pounds per gallon of coating (minus water and exempt solvent)
					 delivered to the application system (0.34 kilogram/liter (kg/liter)).
(2) Metal furniture coating. VOC emissions
					 from metal furniture coating lines (prime and topcoat, or single coat) must not
					 exceed 3.0 pounds per gallon of coating (minus water and exempt solvent)
					 delivered to the application system (0.36 kg/liter).
(3) Coil coating. VOC emissions from the
					 coating (prime and topcoat, or single coat) of metal coils must not exceed 2.6
					 pounds per gallon of coating (minus water and exempt solvent) delivered to the
					 application system (0.31 kg/liter).
(4) Paper coating. VOC emissions from the
					 coating of paper (or specified tapes or films) must not exceed 2.9 pounds per
					 gallon of coating (minus water and exempt solvent) delivered to the application
					 system (0.35 kg/liter).
(5) Fabric
					 coating. VOC emissions from the coating of fabric must not exceed 2.9 pounds
					 per gallon of coating (minus water and exempt solvent) delivered to the
					 application system (0.35 kg/liter).
(6) Vinyl coating. VOC emissions from the
					 coating of vinyl fabrics or sheets must not exceed 3.8 pounds per gallon of
					 coating (minus water and exempt solvent) delivered to the application system
					 (0.45 kg/liter). Plastisol coatings should not be included in
					 calculations.
(7) Can coating. The
					 following VOC emission limits must be achieved, on the basis of VOC solvent
					 content per unit of volume of coating (minus water and exempt solvent)
					 delivered to the application system:

(8)
					 Miscellaneous metal parts and products (MMPP) coating.
(A) VOC emissions from the coating of MMPP
					 must not exceed the following limits for each surface coating type:

						Graphic
(B) If
					 more than one emission limitation in subparagraph (A) of this paragraph applies
					 to a specific coating, then the least stringent emission limitation
					 applies.
(C) All VOC emissions from
					 non-exempt solvent washings must be included in determination of compliance
					 with the emission limitations in subparagraph (A) of this paragraph unless the
					 solvent is directed into containers that prevent evaporation into the
					 atmosphere.
