(Amended May 5, 2006)

RULE 1132. FURTHER CONTROL OF VOC EMISSIONS FROM HIGHEMITTING SPRAY BOOTH FACILITIES 

(a) Purpose and Applicability 

The purpose of this rule is to further reduce volatile organic compound (VOC) 

emissions from spray coating or laminating operations in high VOC-emitting 

facilities. This rule applies to any spray booth facility, except petroleum industry 

facilities, that uses VOC-containing materials that amount to more than 40,000 

pounds (20 tons) per year of VOC emissions in any emission inventory year 

beginning in 1999. Except when a specific exemption applies, the facilities 

subject to this rule shall continue to comply with other rules that are applicable to 

the same operation. 

(b) Definitions 

For the purpose of this rule, the following definitions shall apply: 

(1) APPROVED EMISSION FACTORS are those emission factors 

identified in the Unified Emission Factors (UEFs) table for Open 

Molding of Composites which was published in July 23, 2001, included 

as Attachment A of this rule excluding the “Gelcoat Non-Atomized 

Application” emission factors, or any subsequent emission factors 

developed for open molding of composites that have been approved by 

the Executive Officer, the Executive Officer of the California Air 

Resources Board or designee, and the administrator of the United States 

Environmental Protection Agency or designee. 

(2) CAPTURE SYSTEM is an arrangement of devices such as enclosures, 

plenums, fans and ductworks used to collect VOC-laden air from the 

process area and direct it to the control equipment. 

(3) COMPOSITE MATERIAL is comprised of a gel coat, resin and 

reinforcement element combined in a thermosetting polymer matrix

which is chemically or mechanically bonded.

(4) COMPOSITE MANUFACTURING FACILITY is any facility engaged 

in the manufacturing of products using composite material..

1132 - 2 

(5) EMISSION CONTROL SYSTEM is a combination of capture system(s) 

and control equipment used to reduce, eliminate or control the release of 

VOC to the atmosphere. 

(6) EMISSION INVENTORY YEAR is the annual emission reporting 

period beginning from July 1 of the previous year through June 30 of a 

given year. For example, emission inventory year 1999 covers the 

period from July 1, 1998 through June 30, 1999. 

(7) EXCESS EMISSION REDUCTIONS are VOC emission reductions that 

are not required by any other District requirement as of January 19, 

2001. Excess emission reductions also include any reductions achieved 

on or after January 19, 2001 in excess of the requirements of subdivision 

(c) resulting from a process change subject to best available control 

technology (BACT) as specified in Regulation XIII and implemented 

solely for the purpose of complying with this rule.

(8) FACILITY is any equipment or group of equipment or other VOCemitting activities, which are located on one or more contiguous 

properties within the District, in actual physical contact or separated 

solely by a public roadway or other public right-of-way, and are owned 

or operated by the same person (or by persons under common control), 

or an outer continental shelf (OCS) source as determined in 40 CFR 

Section 55.2. Such above-described groups, if noncontiguous, but 

connected only by land carrying a pipeline, shall not be considered one 

facility. 

(9) GEL COAT is a thermosetting resin surface coating, either pigmented or 

clear, that provides a cosmetic enhancement and improves resistance to 

degradation from exposure to the elements. 

(10) NONATOMIZED APPLICATION is any resin application technology in 

which the resin is not broken into droplets or an aerosol as it travels 

from the application equipment to the surface of an object. 

Nonatomized application technology includes, but is not limited to, 

flowcoaters, flow choppers, pressure-fed rollers, resin impregnators, and 

hand applications using a brush or roller. 

(11) PETROLEUM INDUSTRY FACILITY is any facility primarily engaged 

in the production, refining, storage, transfer or distribution of crude 

petroleum or petroleum products as defined in the Standard Industrial 

Classification for crude petroleum and natural gas (SIC code 1311), 
Rule 1132 (Cont.) (Amended May 5, 2006) 

1132 - 3 

petroleum refining (SIC code 2911), petroleum bulk stations and 

terminals (SIC code 5171), or other related industries (e.g., SIC codes 

4226, 4612, 4613, 4923 and 5541). 

(12) RESIN is any thermosetting polymer used to encapsulate and bind 

together reinforcement fibers in the manufacturing of composites. 

(13) SPRAY BOOTH is any equipment or enclosure used to capture or 

reduce overspray from the application of any coating, lamination, or 

other VOC-containing materials, that requires a permit from the District. 

A spray booth includes standard bench type, floor type, and automotive 

type spray booths, as well as prep stations, spray stations (i.e., a bank of 

filters with a plenum and exhaust fan), and spray rooms. 

(14) SPRAY BOOTH FACILITY is any facility that has installed one or 

more spray booths. A facility subject to a District rule or regulation that 

requires installation of any spray booth is also considered as a spray 

booth facility. 

(15) VOC-CONTAINING MATERIAL is any material that contains VOC 

including, but not limited to, resins, polymers, gel coats, coatings, paints, 

varnishes, stains, sealers, thinners, cleanup solvents, thinning solvents, 

inks, fountain solutions, adhesives, and sealants. VOC-containing 

materials do not include fuels or combustion products. 

(16) VOLATILE ORGANIC COMPOUNDS (VOC) are as defined in Rule 

102. 

(c) Requirements 

On or after the effective date specified in paragraph (e)(1), a person shall not 

operate any spray booth facility subject to this rule, unless the VOC emissions 

from any equipment, activity or operation that applies, or is required by any 

District rule, regulation or permit to apply, VOC-containing materials in a spray 

booth are reduced through the use of the following:

(1) An emission control system that has an overall efficiency of at least 65 

percent by weight; or 

(2) VOC-containing materials that have a VOC content at least 65 percent 

lower than any applicable rule limit in effect as of January 19, 2001; or

The Executive Officer may require more frequent performance testing, as 

necessary. 

(2) The operator of a facility subject to this rule shall submit an initial 

compliance certification report to the Executive Officer no later than 180 

days after the effective date of the requirements. The operator shall then 

submit subsequent compliance certification reports annually within 60 

days after the end of each emission inventory year. The initial and annual 

compliance certification reports shall include the performance testing 

report (if applicable), inventory of materials used, and other procedures 

and information, as necessary to determine compliance with the applicable 

requirements or exemptions. 

(3) The operator shall, at a minimum, maintain the following records for a 

period of at least two years, or five years for facilities subject to Title V 

Permit requirements, and make the records available to the Executive 

Officer upon request: 

(A) Purchase records, or equivalent records as approved by the 

Executive Officer, for all VOC-containing materials used in the 

facility; 

(B) Records of VOC-containing materials in accordance with Rule 109

temperatures, pressures, and flow rates; and 

(D) All measurements, process information, material data, test data, 

and other related information used in or required to support the 

emission determinations for compliance demonstration. 

(h) Exemptions 

The requirements of subdivision (c) shall not apply to the following: 

(1) A facility that has applied for and been issued by the Executive Officer an 

enforceable permit condition that limits the facility-wide VOC emissions 

from the use of VOC-containing materials to no more than 40,000 pounds 

(20 tons) per emission inventory year. The operator must submit complete 

application(s) for change of permit conditions no later than 18 months 

prior to the applicable compliance date pursuant to paragraph (e)(1) and 

comply with the facility-wide emissions limit beginning on the applicable 

effective date pursuant to paragraph (e)(1).

30,000 or greater but less than 60,000 50 

60,000 or greater but less than 90,000 100 

90,000 or greater but less than 275,000 150 

275,000 or greater 225 

If at any time the exhaust flow rate falls in a lesser category, except during 

equipment malfunction, maintenance or repairs for a period not to exceed 

72 hours per occurrence, the allowable VOC emissions of that lesser 

category shall apply. The allowable VOC emissions shall be determined 

based on the monthly average of the past calendar month, calculated by 
Rule 1132 (Cont.) (Amended May 5, 2006) 

1132 - 11 

dividing the total emissions from the spray booth for the month by the 

number of calendar days in the month. The operator of a spray booth that 

meets the above conditions shall submit to the Executive Officer a change 

of condition application for each spray booth employing this exemption by 

September 5, 2004, or no later than 18 months prior to the applicable 

compliance date pursuant to subparagraph (e)(1)(C), whichever is later. 

(3) A spray booth for which the VOC emissions are reduced through the use 

of an existing emission control system in operation under a valid District 

permit as of December 1, 2000, that is not mandatory pursuant to any other 

District requirement or the requirement of any other governmental agency.
