10. National Emission Standards for Hazardous Air Pollutants: Surface Coating Processes. 

Section 112(d) of the 1990 Clean Air Act Amendments requires EPA to promulgate regulations 

establishing emission standards for each category or subcategory of major sources and area sources 

of hazardous air pollutants. These emission standards require maximum achievable control 

technology (MACT) for the reduction of hazardous air pollutant emissions. EPA has promulgated 

General Provisions for National Emission Standards for Hazardous Air Pollutants as published in 40 

CFR Part 63 Subpart A, incorporated by reference herein, along with emission standards for the 

following surface coating source categories:

BASIS STATEMENT

In the State of Maine, nine counties are classified as nonattainment for the federal ozone air quality 

standard. Ground-level ozone formation is caused in part by surface coating operations that emit volatile 

organic compounds (VOC).

This regulation of surface coating facilities restricts the VOC emissions from selected surface coating 

operations. Under Section 184 of the Clean Air Act Amendments of 1990, the State of Maine must 

submit plans to control VOC from all sources covered by a Control Technique Guideline (CTG) issued 

before November 15, 1990.

In addition to the Basis Statement above, the Department has filed with the Secretary of State its 

response to comments received during the comment period. 

BASIS STATEMENT FOR AMENDMENTS OF JANUARY 28, 1998

These amendments simplify compliance for surface coating facilities through the establishment of an 

exemption for the use of coatings used on-site for maintenance and repair activities, and a de minimus 

threshold. The amendments also remove the once-in, always-in provisions for sources accepting certain 

license restrictions, establish explicit work practice standards for the use of solvents in cleanup 

operations, and incorporate the Federal MACT requirements for several surface coating categories. 

In addition to this Basis Statement, the Department has filed a supplemental Basis Statement with the 

Secretary of State that summarizes its responses to comments received during the comment period.

BASIS STATEMENT FOR AMENDMENTS OF JANUARY 6, 2011

In the late 1970’s, EPA published CTGs recommending VOC controls for flat wood paneling and metal 

furniture, which were updated in September 2006 and September 2007, respectively. 

The amendments expand the types of paneling regulated by Chapter 129 to include exterior siding and 

tileboard. Emission limits for these two categories were not addressed in the 1978 CTG document. The 

amendments lower the threshold above which sources are subject to the rule to 15 lbs/day of VOC (from 

10 tons per year12 month rolling period). VOC emission limits are expressed in weight per volume units 

instead of a weight per surface area coated.

The amendments provide VOC limits for eight types of coatings used on metal furniture and list 6 

coatings that are exempt from the rule. The amendments lower the threshold to 15 lbs/day (from 10 tons 

per year 12 month rolling period) above which metal furniture sources are subject to VOC controls.

In addition to this Basis Statement, the Department has filed a supplemental Basis Statement with the 

Secretary of State that summarizes its responses to comments received during the comment period.

BASIS STATEMENT FOR AMENDMENTS OF [MONTH] [DAY], 2014

In 2008, the EPA published CTGs recommending VOC controls for miscellaneous metal and plastic parts 

coatings. 

The amendments expand Chapter 129 to include miscellaneous metal and plastic parts, which include, 

but are not limited to, metal and plastic components of the following types of products as well as the 

products themselves: fabricated metal products, molded plastic parts, small and large farm machinery, 

commercial and industrial machinery and equipment, automotive or transportation equipment, interior or 

exterior automotive parts, construction equipment, motor vehicle accessories, bicycles and sporting 

goods, toys, recreational vehicles, pleasure craft (recreational boats), extruded aluminum structural 

components, railroad cars, heavier vehicles, lawn and garden equipment, business machines, laboratory 

and medical equipment, electronic equipment, steel drums, metal pipes, and numerous other industrial 

and household products. The EPA had not previously issued a CTG covering these products. The 

amendment applies a threshold to categories 4 through 6 of 2.7 tons per 12 month rolling period above 

which sources are subject to the rule. VOC emission limits are expressed in weight per volume units 

instead of a weight per surface area coated.

The amendments provide VOC limits various coating processes based upon reductions being achieved by 

either a low VOC coat or in combination with other control techniques. The Rule includes three 

categorical exemptions and additional exemptions based upon the nature of the coating applied.
