CHAPTER 129: SURFACE COATING FACILITIES

SUMMARY: This regulation establishes consistent requirements for testing, 

evaluating and limiting the emissions of volatile organic compounds (VOC) and 

Hazardous Air Pollutants (HAP) from selected surface coating operations. VOC 

surface coating facilities can select one of three compliance methods: low 

solvent content coating technology, daily-weighted averaging, and add-on air 

pollution control devices.

1. Scope/Applicability

A. Source applicability. This Chapter applies to all new and existing surface coating facilities 

under the following surface coating categories:

(1) Surface coating of cans;

(2) Surface coating of fabric;

(3) Surface coating of vinyl;

(4) Surface coating of metal furniture;

(5) Surface coating of flatwood paneling; and

(6) Surface coating of miscellaneous metal and plastic parts and products.

B. Testing and recordkeeping applicability. The owner or operator of a surface coating unit, line 

or operation subject to this chapter shall comply with the testing and compliance procedures in 

Section 6, Test Methods and Compliance Procedures, and the certification and recordkeeping 

requirements in Section 7, “Initial Compliance Certification and Recordkeeping Procedures”, 

both of this chapter.

C. Emission limitations applicability

(1) Any surface coating unit, line or operation under categories 1 through 3, as specified in 

Subsection 1(A) above and within this chapter, whose maximum theoretical emissions of 

VOC from all coating units, lines or operations at the surface coating facility under the same 

surface coating category are ten (10) tons VOC per 12 month rolling period or greater, shall 

comply with the applicable emission limitations under Section 4 of this chapter.

(2) Any surface coating unit, line or operation under categories 4 through 6 as specified in 

Subsection 1(A) above and within this chapter, whose total actual emissions of VOC from all 

coating units, lines, or operations at the surface coating facility under the same surface 

coating category are 2.7 tons per 12 month rolling period or greater, shall comply with the 

applicable emission limitations under Section 4 of this chapter.

D. Changes in applicability. Any surface coating unit, line or operation that becomes or is 

currently subject to these provisions under Subsection 1(C) of this chapter remains subject to the 

provisions, even if its emissions later decrease, except that any source which has reduced its 

actual VOC emissions below the applicability threshold established under Subsection 1(C) shall 

be exempt from the applicable emissions limitations established under Section 4 of this chapter, 

provided that both of the following conditions are met:

(1) The owner or operator can demonstrate that the actual VOC emissions occurring in the 

consecutive 12-month period after said reduction was implemented were no more than 80% 

of the relevant applicability threshold; and 

(2) The owner or operator accepts an enforceable permit containing restrictions which limit the 

combined actual VOC emissions, during any 12-month period from the source or all process 

operations associated with a specific classifiable process, below 80% of the relevant 

applicability threshold.

If the source's emissions later increase to greater than 80% of the applicability threshold during 

any consecutive 12 month period, then the facility must immediately comply with the emission 

limitations of Section 4 of this chapter.

.

E. Exemptions. The following surface coating operations are exempt from the requirements of this 

chapter:

(1) Coating units, lines or operations whose total actual coatings usage from all coating units, 

lines or operations at the surface coating facility under the same surface coating category is 

less than 50 gallons per 12 month rolling period of coatings. Non-VOC coatings (such as 

zinc-arc, Ultra Violet, powder, or vapor curecoatings) are excluded when calculating 

compliance with this exemption;

(2) Facilities exclusively utilizing powder coatings or other non-VOC methods of coating are

exempt from the requirements of this chapter.

(3) Surface coating of the following:

(a) Exterior of completely assembled aircraft,

(b) Major aircraft subassemblies which are exposed to the exterior of the aircraft,

(c) Automobile, light-duty truck, and heavy duty truck refinishing,

(d) Exterior of completely assembled marine vessels, and

(e) Major marine vessel subassemblies which are exposed to the exterior of the vessel;
