Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

Rule 245, Surface Coating of Metal Parts and Products, was originally adopted by the District on December 8, 

2009 to meet Reasonably Available Control Technology – State Implementation Plan (RACT SIP) requirements.

 

In September 2008, toward the end of the time period that Rule 245 was being finalized, the U.S. Environmental 

Protection Agency released "Control Techniques Guidelines (CTG) for Miscellaneous Metal and Plastic Parts 

Coatings.” The CTG provided updated guidance for determination of Reasonably Available Control Technology 

for metal surface coating operations. Due to the timing of the CTG, the District was not able consider the CTG in 

Rule 245.

This Staff Report addresses amendments that are proposed to Rule 245 based on the CTG. This rule 

amendment fulfills the District requirement to adopt a measure that incorporates the CTG within one year of the 

CTG’s release.

Changes to the Rule include:

Section 105 Exemptions for Specific Operations and Coatings

• Elimination of the exemption for stripping of cured coatings, cured adhesives, and cured inks.

• Elimination of the exemption for the coating categories of aircraft, aerospace vehicles, coils, and conformal 

coatings.

• Elimination of the exemption for hand-lettering, electrocoating, optical anti-reflective coatings, mobile 

equipment, and vacuum-metalizing.

• Clarifying a partial exemption for repair and touchup – only exempt from application method requirements.

• Retention of a partial exemption for coating operations used for stencil, safety indicating, solid film 

lubricants, electrical insulating and thermal conduction, and magnetic data storage discs – adding a requirement 

to meet work practice standards and retaining recordkeeping requirements.

Section 301 VOC Limits

• Deletion of VOC limits for categories of aluminum coatings, nonskid, and solid film lubricants.

• Addition of VOC limits for categories of electrical insulating varnish and military specification.

• Placement of iridescent coatings with the metallic coating category.

• Elimination of “All Other” coating category.

Section 302 Application Methods

• Requirement that U.S. EPA approve alternative application methods.

Section 304 Work Practice Requirements

• Addition of a new section that addresses work practice requirements for all operations – including 

minimizing spillage and usage of closed containers to transport and store and dispose of VOC containing 

materials.

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split 

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 4

Percent in Nonattainment Area: 100% 

Number of Large (> 100 TPY) Sources Controlled: 0 Percent in Nonattainment Area: N/A% 

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as 

necessary): N/A

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No 

If Yes, Those Limits are in Section(s) 301, Limits on VOC Content of Coatings for Metal Parts and Products of the Rule. 

Other Methods in the Rule for Achieving Emission Reductions are: Section 302, Application Methods; Section 303,

Surface Preparation and Cleanup Requirements; Section 304, Work Practices; and Section 305, Emission Control 

Equipment.

V. OTHER REQUIREMENTS

The Rule Contains: 

Emission Limits in Section(s): 301, Limits on VOC Content of Coatings for Metal Parts and Products Work Practice 

Standards in Section(s): 304, Work Practices
