MINUTES OF THE GOVERNING BOARD OF THE ANTELOPE VALLEY AIR QUALITY MANAGEMENT DISTRICT LANCASTER, CALIFORNIA AGENDA ITEM1 DATE: July 16, 20 13 RECOMMENDATION: 1 . Conduct a public hearing to consider the amendment of Rule 1124

- Aerospace Assembly and Component Man71facturing Operations; 2. Continue hearing to August 20, 2013
. SUMMARY: Rule 1124 is proposed for amendment to update the rule and align specialty coating categories with t he 1998 United States Environmental Protection Agency (US EPA) Control T echniques Guideline (CTG) entitled Control ofVolatile Organic Compound Emissions from Coating Operations atAerospace Man71facturing and Rework Operations. Continuation ofthe proposed action is necessary to address comments received from the USEPA. BACKGROUND: On July 1, 1997 the Antelope Valley Air Pollut ion Control D istrict (AVAPCD) was created pursuant to statute (former Health & Safety (H&S) Code §40106, A.B. 266-Knight Ch. 542, statutes of 1996) and assumed all air pollution control responsibilities from the South Coast Air Quality Management District (SCAQMD) for the area of Los Angeles County outside the South Coast Air Basin (SCAB)
. The SCAQMD rules in effect within the jur isdiction ofthe AVAPCD remained in effect until the AVAPCD Governing Board superseded, amended, or rescinded them. On January 1, 2002 the Antelope Valley Air Quality Management District (AV AQMD) was created pursuant to statute (H &S Code §41300 et seq.) to replace the AVAPCD
. Once again the rules in effect at the time ofthe change remained in effect until the AVAQMD Governing Board superseded, amended or rescinded them. Rule 1124 was last amended by the SCAQMD on December 13, 1996, and subsequently amended by the AVAQMD on March 20, 2007
. The Federal Clean Air Act (FCAA) requires areas designated nonattainment for ozone and classified moderate and above to adopt and maintain Reasonably Available Control Technology (RACT) rules for source categories emitting Volatile Organic Compounds (VOC) and oxides of nitrogen (NOx) for which USEPA has issued a CTG document. In addition, such areas are required to adopt and maintain RACT rules for all other major stationary sources ofVOCs and NOx (42 U
. S
.C. §75 1l a(b)(2); FCAA §182(b)(2)). The Antelope Valley area has been designated non-attainment for the eight hour ozone

ITEM CONTINUEDMINUTES OF THE GOVERNING BOARD OF THE ANTELOPE VALLEY AIR QUALITY MANAGEMENT DISTRICT LANCASTER, CALIFORNIA AGENDA ITEM1 PAGE2 On March 10, 1998 USEPA adopted a CTG entitled Control of Volatile Organic Compound Emissions from Coating Operations atAerospace Manufacturing and Rework Operations. In addition, USEPA also has promulgated and amended Maximum Achievable Control Technology (MACT) Standard for Aerospace Manufacturing and Rework Facilities (40 CFR 63 Subpart GG, commencing with §63.741). The AVAQMD most recently amended Rule 1124 on March 20, 2007 given the issuance ofthe CTG and amendments to the MACT Standard as well as technological advances 

### in coatings use and technology. USEPA indicated that there were several specialty coatings from the CTG that were not included in the 2007 rule amendment. The propos ed amendments are primarily designed to update the specialty coating categories and definitions to harmonize with the CTG as requested by USEP A. Definitions have been added for following the specialty coating categories: Ablative Coating; Bearing Coating; Bonding Maskant; Caulking and Smoothing Compound; Chemical Agent-Resistant Coating (CARC); Chemical Milling Maskant; Chemical Processing Maskant; Coating; Commercial Exterior Aerodynamic Structure Primer; Commercial Inter ior Adhesive; Compatible Substrate Primer; Corrosion Prevention System Compound; Critical Use and Line Sealer Maskant; Cryogenic Flexible Primer; Cryoprotective Coating; Cyanoacrylate Adhesive; Electrostatic Discharge and Electromagnetic Interference (EMI) Coating (Includes Space Vehicles); Elevated-Temperature Skydrol-Resistant Commercial Primer; Epoxy Polyamide Topcoat; Fastener; Fire-Resistant (Interior) Coating (Space); Flexible Primer; Insulation Covering; Intermediate Release Coating; Lacquer Coating; Part Marking Coating; Rocket Motor Bonding Adhesive; Rocket Motor Nozzle Coating; Rubber-based Adhesive; Screen Print Ink; Seal Coat Maskant; Silicone Insulation Material; Specialized Function Coating; Specialty Coating; Thermal Control Coating; and, Wet Fastener Installation Coating. VOC limits for specialty coatings have been updated to include categories in the CTG that were not covered by the previous rule amendment. The proposed amendment also confom1s the formatting to the standard AVAQMD rule format, removes several unused definitions, updates several definitions for consistency with the CTG, removes an exemption for Temporary Marking Coatings and Materials Marking Coating for consistency with Part Marking Coating category, and cross references have been updated. A Notice of Exemption , Categorical Exemption (Class 8; 14 Cal. Code Reg. § 15308) will be prepared by the AVAQMD for the amendment ofRule 1124 pursuant to the requirements of CEQA. REASON FOR RECOMMENDATION: Health & Safety Code §§40702 and 40703 require the Governing Board to hold a public hearing before adopting rules and regulations. A lso, 42 U.S.C. §7410(1) (FCAA §110(1)) requires that all State Implementation Plan (SIP) revisions beMINUTES OF THE GOVERNING BOARD OF THE ANTELOPE VALLEY AIR QUALITY MANAGEMENT DISTRICT LANCASTER, CALIFORNIA
