06/06/94. Revisions approved by EPA 07/25/96 (61 FR 38591) at 

52.970(c)(64) effective 08/26/96.)

 A. Except as provided in LAC 33:III.2123.B and C, any emission 

source using organic solvents having an emission of organic solvents of 

more than three pounds (1.3 kilograms) per hour or 15 pounds (6.8 

kilograms) per day shall reduce the emission, where feasible, by 

incorporating one or more of the following control methods:

 1. incineration, provided 90ninety percent of the carbon in the 

organic compounds being incinerated is oxidized to carbon dioxide 

(except as provided in LAC 33:III.2123.D).

 2. carbon adsorption of the organic compounds.

 3. any other equivalent means as may be approved by the 

administrative authority. Once a source exceeds the emission cutoff 

specified in this paragraph that source shall be subject and shall 

remain subject to the requirements of LAC 33:III.2123.A regardless of 

future emission rates.

 B. Soldering operations, painting and coating operations, not 

listed in LAC 33:III.2123.C, and dry cleaning operations using organic 

solvents which are not considered photochemically reactive shall be 

considered for exemption from the requirements of LAC 33:III.2123.

 1. For the purposes of the statementthis Subsection, a 

photochemically reactive solvent is any solvent with an aggregate of 

more than 20 percent of its total volume composed of the chemical 

compounds classified below or which exceeds any of the following 

individual percentage composition limitations, referred to the total 

volume of solvent:

 a. a combination of hydrocarbons, alcohols, aldehydes, 

esters, ethers, or ketones having an olefinic or cycloolefinic type of 

unsaturation: five 5 percent;

 b. a combination of aromatic compounds with eight or more 

carbon atoms to the molecule except ethylbenzene: eight8 percent;

 c. a combination of ethylbenzene, ketones having branched 

hydrocarbon structures, trichloroethylene or toluene: 20 percent.

Whenever any organic solvent or any constituent of an organic solvent 
may be classified from its chemical structure into more than one of the 

above groups of organic compounds, it shall be considered as a member 

of the most reactive chemical group, that is, that group having the 

least allowable percent of the total volume of solvents.

 C. Surface Coating Industries. No person may cause, suffer, allow, 

or permit volatile organic compound (VOC) emissions from the surface

 D. Control Techniques

 1. If add-on controls such as incinerators or vapor recovery 

systems are used to comply with the emission limitation requirements, 

in terms of pounds per gallon of solids as applied (determined in 

accordance with LAC 33:III.2123.Paragraph D.8 of this Section), the 

volatile organic compound capture and abatement system shall be at 

least 80 percent efficient overall. All surface coating facilities 

shall submit to the Office of Environmental services, Air Permits 

Division, administrative authority, for approval, design data for each 

capture system and emission control device whichthat is proposed for 

use. The effectiveness of the capture system (i.e. capture efficiency) 

shall be determined using the procedure specified in LAC 

33:III.2123.Paragraph E.6 of this Section.

 2. If a person wishes to use low solvent technology to meet any 

of the emission limits specified in Regulation LAC 33:III.2123.C.1 

through - 10 and if the technology to be used for any particular 

application is not now proven but is expected to be proven in a 

reasonable length of time, he may request a compliance date extension 

from the administrative authority*. Compliance date extensions will 

require progress reports every 90 days, or as directed, to show 

reasonable progress, as determined by the administrative authority, 

toward technology to meet the specified emission limitation.

 3. Compliance will be determined by the procedure specified in 

"Control of Volatile Organic Emissions for Existing Stationary Sources. 

 Vol 2-Surface Coating of Cans, Coils, Paper, Fabric, Autos and Lt. 

Duty Trucks", (EPA 450/2-77-008), the procedures specified in 

"Measurement of Volatile Organic Compounds" (EPA-450/2-78-041), a 

method approved by the administrative authority or certification from 

the paint manufacturer concerning the solvent makeup of the paint. 

Exempt solvents shall be treated the same as water in calculating the 

VOC content per gallon of coating. Exempt solvents are those compounds 

listed in LAC 33:III.2117.

 4. Compliance with the alternative emission limit established 

in LAC 33:III.2123.C.6 of 15.1 pounds of VOC per gallon of solids 

deposited shall be determined in accordance with EPA's "Protocol for 

Determining the Daily Volatile Organic Compound Emission Rate of 

Automobile and Light Duty Truck Topcoat Operations", EPA 450/3-88-018, 

December, 1988.

 5. A plant wide emission reduction plan may be approved by the 

administrative authority* if it can be demonstrated by the surface 

coating facility that any emissions in excess of those allowed for a 

given coating line will be compensated for by reducing emissions from 

regulated sources within the surface coating facility.

 6. Surface coating facilities on any property in Ascension,

Calcasieu, East Baton Rouge, Iberville, Livingston, Pointe Coupee, and 

West Baton Rouge parishes whichthat when controlled have a potential to 
emit at maximum production a combined weight (total from the property) 

of volatile organic compoundVOCs less than 10 tons in any consecutive 

12 calendar months are exempt from the provisions of LAC 

33:III.2123.C.1 through 10Subsection C of this Section. Surface 

coating facilities on any property in parishes other than Ascension, 

Calcasieu, East Baton Rouge, Iberville, Livingston, Pointe Coupee, and 

West Baton Rouge whichthat when uncontrolled have a potential to emit a 

combined weight of volatile organic compoundVOCs less than 100 pounds 

(45 kilograms) in any consecutive 24-hour period are exempt from the 

provisions of LAC 33:III.2123.C.1 through 10Subsection C of this 

Section.

 7. Soldering and surface coating facilities or portions 

thereof, may request from the administrative authority* exemption from 

the requirements of LAC 33:III.2123.C if all of the following 

conditions are met:

 a. the affected portion of the facility will not emit 25 

tons per year (TPY) or more of VOC if the facility is located in the 

parish of Ascension, East Baton rouge, Iberville, Livingston, or West 

Baton Rouge, or more than 50 tons per yearTPY or more of VOC if located 

in any other parish;

 b. that the only practical means of VOC control is thermal 

oxidization;

 c. that the substance to be emitted is not toxic;

 d. that the moles of fuel used would exceed the moles of 

VOC destroyed;

 e. that the reasonable control of the VOC would result in a 

net increase of emissions from the facility.

 f. Tthe exemption will be described in detail in the 

Compliance Orders, under Section 110a.(3) of the Federal Clean Air Act, 

adopted by the administrative authority*.

 8. Compliance with an emission limit specified under Subsection 

C of this Section may be demonstrated, in terms of pounds per gallon 

solids as applied, based upon the daily weighted average of a coating 

type within a single coating line. The equivalent emission limit in 

terms of pounds per gallon solids as applied (Es) shall be determined 

using the following calculation:

 Ds = 7.36 pounds volatile organic compound per gallon 

volatile organic compound (i.e., density of reference solvent);

 Ec = Emission limit found in Subsection C. of this Section, 

in terms of pounds per gallon of coating (less water and exempt 

solvents);

 Es = Emission limit equivalent to Ec, but in terms of pounds 

per gallon solids as applied;
 Vs = Gallon solids per gallon coating (less water and exempt 

solvents).

 Vs = (1 - Ec/Ds)

 Es = Ec/Vs

 9. If improved transfer efficiency application equipment is 

used to comply with the emission limitations in terms of pounds per 

gallon solids deposited, the improved transfer efficiency equipment 

shall be tested following procedures approved in advance by the 

administrative authority* and consistent with those transfer efficiency 

testing procedures specified in Paragraph E.5 of this Section. The 

applicable emission limit shall be calculated using the transfer 

efficiency baseline established by the administrative authority* and 

compliance shall be determined following a calculation procedure also 

approved by the administrative authority*.

 E. Testing. Compliance with LAC 33:III.2123.A, C and D shall be 

determined by applying the following test methods, as appropriate:

 1. Test Method 24 (40 CFR Part 60, Appendix A, as incorporated 

by reference at LAC 33:III.6083003) with a one-hour bake;

 2. Test Method 1 through - 4 (40 CFR Part 40, Appendix A, as
