AGENDA ITEM1 

DATE: July 16, 2013 

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 the 1998 United States Environmental Protection 

Agency (USEPA) Control Techniques Guideline (CTG) entitled Control of Volatile 

Organic Compound Emissions from Coating Operations at Aerospace Man71facturing 

and Rework Operations. Continuation of the proposed action is necessary to address 

comments received from the USEP A. 

BACKGROUND: On July 1, 1997 the Antelope Valley Air Pollution Control District 

(AV APCD) 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 jurisdiction of the AV APCD 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the AVAPCD Governing Board superseded, amended, or rescinded them.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 of the 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Board superseded, amended or rescinded them.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. §751 l a(b)(2); FCAA §182(b)(2)). The 

Antelope Valley area has been designated non-attainment for the eight hour ozone

AGENDA ITEM1 PAGE2 

On March 10, 1998 USEP A adopted a CTG entitled Control of Volatile Organic Compound 

Emissions from Coating Operations at Aerospace Manufacturing and Rework Operations. In 

addition, USEP A 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 of the 

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 proposed 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 

Interior 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 AV AQMD 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 of Rule 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. Also, 42 

U.S.C. §7410(1) (FCAA §110(1)) requires that all State Implementation Plan (SIP) revisions be

from the USEP A requiring additional research.
