Approved by EPA 05/05/94 (59 FR 23166) at 52.970(c)(60) effective 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 ninety 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 statement, 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 percent;
b. a combination of aromatic compounds with eight or more carbon atoms to the molecule except ethylbenzene: eight 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 coating of any materials affected by LAC 33:III.2123.C to exceed the emission limits as specified in this regulation.

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.D.8), the volatile organic compound capture and abatement system shall be at least 80 percent efficient overall. All surface coating facilities shall submit to the administrative authority, for approval, design data for each capture system and emission control device which 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.E.6.
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, East Baton Rouge, Iberville, Livingston, Pointe Coupee, and West Baton Rouge parishes which when controlled have a potential to emit at maximum production a combined weight (total from the property) of volatile organic compounds less than 10 tons in any consecutive 12 calendar months are exempt from the provisions of LAC 33:III.2123.C.1 through 10. Surface coating facilities on any property in parishes other than Ascension, East Baton Rouge, Iberville, Livingston, Pointe Coupee, and West Baton Rouge which when uncontrolled have a potential to emit a combined weight of volatile organic compounds 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 10.
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 more than 50 tons per year of VOC;
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.
The 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 (LAC 33:III.6083) with a one-hour bake;
2. Test Method 1 through 4 (LAC 33:III.6001, 6003, 6009 and 6013, respectively) for determining flow rates;
3. Test Method 18 (LAC 33:III.6071) for measuring gaseous organic compound emissions by gas chromatographic analysis;
4. Test Method 25 (LAC 33:III.6085) for determining total gaseous nonmethane organic emissions as carbon;
5. Protocol for Determining the Daily Volatile Organic Compound Emission Rate of Automobile and Light-Duty Truck Topcoat Operations (Document No. EPA-450/3-88-018 dated December, 1988) for determining transfer efficiency, oven loading and incinerator destruction efficiency;
6. performance test procedures described in LAC 33:III.3694;
7. additional performance test procedures, or equivalent test methods, approved by the administrative authority*.
F. Recordkeeping. The owner/operator of any surface coating facility shall maintain records at the facility to verify compliance with or exemption from LAC 33:III.2123. The records shall be maintained for at least two years and will include, but not be limited to, the following:
1. records of any testing done in accordance with LAC 33:III.2123.E.
2. the owner/operator of any facility subject to LAC 33:III.2123 shall install and maintain monitors to accurately measure and record operational parameters of all required control devices as necessary to ensure the proper functioning of those devices in accordance with the design specifications, including but not limited to:
a. the exhaust gas temperature of direct-flame incinerators and/or the gas temperature immediately upstream and downstream of any catalyst bed;
b. the total amount of volatile organic compounds recovered by carbon adsorption or other solvent recovery systems during a calendar month;
c. the dates and reasons for any malfunction of a required control device and the estimated quantity and duration of volatile organic compound emissions during the upset period; and
d. the exhaust gas VOC concentration of a carbon adsorption system to determine breakthrough.
3. material data sheets which document the volatile organic compound content, composition, solids content, solvent density, and other relevant information regarding each coating and/or solvent used.
4. records used for determining the daily volatile organic compound emission rate of automobile and light-duty truck topcoat operations as specified in Document No. EPA-450/3- 88-018 dated December, 1988.
