Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 129 - SURFACE COATING FACILITIES › Section 096-129-4 - Emission Limitations

Current through 2024-29, July 17, 2024
The owner or operator of a surface coating unit, line or
				  operation subject to this chapter shall comply with the applicable emission
				  limitations in Subsections
				  4(A) through
				  4(F) of this chapter
				  below, by the use of Low Solvent Content Coating Technology, Daily-Weighted
				  Averaging, or Add-On Air Pollution Control Devices, as specified in Section
				  3 of this chapter. Emission
				  limitations on VOC content for all surface coating categories are expressed in
				  units of mass of VOC in kilograms (kg) or lb per volume of coating in liters
				  (l) or gallons (gal), excluding water and exempt compounds, as applied.
				  Emission limitations on VOC content for metal furniture and flatwood paneling
				  are also expressed in units of mass of VOC in kilograms (kg) or pounds (lb) per
				  volume in liters (l) or gallons (gal) of solids, as applied.
If more than one surface coating category and emission
				  limitation applies to a specific coating operation, then the least stringent
				  emission limitation controls.
A.
Emission limitations for surface coating of cans
.This subsection
				applies to any can coating unit subject to emission limitations as specified in
				Sections 1 and 2 of this chapter, and used to apply the following coatings:
				sheet basecoat, exterior basecoat, over varnish, interior body spray coat,
				side-seam-spray coat, two-piece can exterior end coat and end sealing compound
				coat. The owner or operator of a can coating unit subject to this subsection
				may not cause or allow the release of VOC that exceeds the following emission
				limitations:

B.
Emission limitations for surface coating of fabric.
This subsection
				applies to any fabric coating unit or line subject to emission limitations as
				specified in Sections 1 and 2 of this chapter. The owner or operator of a
				fabric coating unit or line subject to this subsection may not cause or allow
				the release of VOC that exceeds the following emission limitation:
0.35 kg/l (2.9 lb/gal)
C.
Emission limitations for surface
				coating of vinyl.
This subsection applies to any vinyl coating line
				subject to emission limitations as specified in Sections 1 and 2 of this
				chapter. This subsection does not apply to the application of vinyl plastisol
				to fabric to form the substrate that is subsequently coated. The owner or
				operator of a vinyl coating line subject to this subsection may not cause or
				allow the release of VOC that exceeds the following emission limitation:
0.45 kg/l (3.8 lb/gal)
D.
Emission limitations for surface
				coating of metal furniture
(1) This
				subsection applies to any metal furniture coating unit subject to emission
				limitations as specified in Sections 1 and 2 of this chapter. By January 1,
				2012, the owner or operator of a metal furniture coating unit subject to this
				subsection shall meet the VOC emission limitations in either Table 1 or Table
				2.
