Subject: Submittal of Recently Amended Rules 102 (Definitions), 202 (Exemptions to Rule 201), 321 

(Solvent Cleaning Machines and Solvent Cleaning), 330 (Surface Coating of Metal Parts and 

Products), 337 (Surface Coating of Aerospace Vehicles and Components), 349 (Polyester Resin 

Operations), and 353 (Adhesives and Sealants)

Dear Mr. Guzzetta:

On June 21, 2012, the Santa Barbara County Air Pollution Control District Board of Directors held a Public Hearing 

on adopting amendments to Rule 102 (Definitions), Rule 202 (Exemptions to Rule 201), Rule 321 (Solvent Cleaning 

Machines and Solvent Cleaning), Rule 330 (Surface Coating of Metal Parts and Products), Rule 337 (Surface 

Coating of Aerospace Vehicles and Components), Rule 349 (Polyester Resin Operations), and Rule 353 (Adhesives 

and Sealants). After the Public Hearing, the Board adopted the amended rules. Transmitted with this letter are the 

adopted amended rules for inclusion into the California State Implementation Plan.

Changes to the rules are summarized below:

 Rule 102, Definitions

The District added:

 an enclosed cleaning system definition,

 an exempt compound definition,

 chemical names to the fluorinated gases definition, 

 four USEPA-identified exempt compounds to the reactive organic compound definition, and 

 terms common to the other amended rules.

 Rule 202, Exemptions to Rule 201

Replaced EPA Method 24 with South Coast AQMD Method 313-91. Also made minor revisions (e.g., add rule and 

test method titles).

 Rule 321, Solvent Cleaning Machines and Solvent Cleaning

Revised the Section B.6 exemption to clarify that the exemption does not apply to solvent cleaning machines when 

an operation-specific rule indicates such equipment is subject to Rule 321 devices/methods to be used when 

performing solvent cleaning. Please note the substantive parts of Rule 321 were not amended and that EPA 

approved Rule 321 into the State Implementation Plan on September 29, 2011 (76 FR 60376).

 Rule 330, Surface Coating of Metal Parts and Products

Added Rule 321-type exemptions, definitions, and general solvent cleaning, recordkeeping, reporting, source 

testing, and compliance provisions.

 Rule 337, Surface Coating of Aerospace Vehicles and Components

In addition to the changes outlined for Rule 330, the District added:

1. Adhesive and sealant provisions; and 

2. Coating categories and limits from a USEPA Control Techniques Guideline (CTG) document and a federal 

regulation for the source category. The District is also lowering the stripper ROC limit from 400 to 300 

grams per liter in response to suggestions by the ARB and the USEPA.

 Rule 349, Polyester Resin Operations

The changes outlined for Rule 330 were included in proposed amended Rule 349. Lower polyester resin material 

monomer contents limits and a higher add-on control equipment overall efficiency limit were also added. These 

new provisions have a 24-month phase-in period to allow for product sale-through and available stock depletion. 

Lastly, staff made minor changes to the rule’s Attachment A, “Static Method for Determination of Volatile 

Emissions from Polyester and Vinyl Ester Resins.”

 Rule 353, Adhesives and Sealants

The District amended the rule to include Rule 321-type provisions like in the other rules. We added application 

equipment requirements and stripper use provisions. The ROC-content limit on several products were also reduced.

The following is provided to clarify our responses to the SIP Completeness Checklist and the associated material we 

are submitting:

Andy Steckel to Patrick Au).
