100 GENERAL

101 PURPOSE: The purpose of this Rule is to limit the emissions of organic solvents into the atmosphere that may result from the use of organic solvents.
102 APPLICABILITY: The provisions of this Rule apply to any person that uses organic solvents except as provided by Section 110 of this Rule.
110

EXEMPTIONS: The provisions of this Rule shall not apply to:

110.1 The manufacture of organic solvents or the transport or storage of organic solvents or materials containing organic solvents.

110.2 The use of equipment for which other requirements are specified by these Regulations or which are exempt from air pollution control requirements by said Rules.

110.3 The spraying or other employment of insecticides, pesticides, or herbicides.

110.4 The employment, application, evaporation, or drying of saturated halogenated organic solvents or perchloroethylene.

110.5 The use of any material in any article, machine, equipment, or other contrivance described in Sections 301, 302, 303, or 304 of this Rule, if:

  1. The volatile content of such material consists only of water and organic solvents;
  2. The organic solvents comprise not more than 20 percent of said volatile content;
  3. The volatile content is not photochemically reactive as defined in Section 203 of this Rule; and
  4. The material does not come into contact with flame.

200 DEFINITIONS
201 ORGANIC MATERIALS: Chemical compounds of carbon excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides, metallic carbonates, and ammonium carbonate.
202 ORGANIC SOLVENTS: Diluents and thinners and are defined as organic materials which are liquids at standard conditions and which are used as dissolvers, viscosity reducers, or cleaning agents, except that such materials which exhibit a boiling point higher than 220oF (104.4oC) at 0.5 millimeter mercury absolute pressure or having an equivalent vapor pressure shall not be considered to be solvents unless exposed to temperatures exceeding 220oF (104.4oC).
203 PHOTOCHEMICALLY REACTIVE SOLVENT: 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:

203.l A combination of hydrocarbons, alcohols, aldehydes, esters, ethers, or ketones having an olefinic or cycloolefinic type of unsaturation: 5 percent;

203.2 A combination of aromatic compounds with eight or more carbon atoms to the molecule except ethylbenzene: 8 percent;

203.3 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.

300 STANDARDS

301 ORGANIC MATERIALS: A person shall not discharge into the atmosphere more than 15 pounds of organic materials in any one day, nor more than 3 pounds in any one hour, from any article, machine, equipment, or other contrivance in which any organic solvent or any material containing organic solvent comes into contact with flame or is baked, heat-cured, or heat-polymerized, in the presence of oxygen, unless said discharge has been reduced by an overall control and capture efficiency of at least 85 percent on a mass basis by air pollution control equipment. Those portions of any similar or identical series of articles, machines, equipment, or other contrivances used for processing identically continuous web, strip, or wire, and which emit organic materials and which use operations described in this section shall be collectively subject to compliance with this section.
302 PHOTOCHEMICALLY REACTIVE SOLVENTS: A person shall not discharge into the atmosphere more than 40 pounds of organic materials in any one day, nor more than 8 pounds in any one hour, from any article, machine, equipment, or other contrivance used under conditions other than described in Section 301 of this Rule, for employing or applying any photochemically reactive solvent, as defined in Section 203 of this Rule, or material containing such photochemically reactive solvent, unless said discharge has been reduced by an overall control and capture efficiency of at least 85 percent on a mass basis by air pollution control equipment. Emissions of organic materials into the atmosphere resulting from air or heated drying of products for the first 12 hours after their removal from any article, machine, equipment, or other contrivance described in this section shall be included in determining compliance with this section. Emissions resulting from baking, heat-curing, or heat-polymerizing as described in Section 301 of this Rule shall be excluded from determination of compliance with this section. Those portions of any similar or identical series of articles, machines, equipment, or other contrivances used for processing identically continuous web, strip, or wire, and which emit organic materials and which use operations described in this section shall be collectively subject to compliance with this section.
303 NON-PHOTOCHEMICALLY REACTIVE SOLVENTS: A person shall not discharge into the atmosphere more than 3,000 pounds of organic materials in any one day, nor more than 450 pounds in any one hour, from any article, machine, equipment, or other contrivance in which any non-photochemically reactive organic solvent or any material containing such solvent is employed or applied, unless said discharge has been reduced by an overall control and capture efficiency of at least 85 percent on a mass basis by air pollution control equipment. Emissions of organic material into the atmosphere resulting from air or heated drying of products for the first 12 hours after their removal from any article, machine, equipment, or other contrivance described in this section shall be included in determining compliance with this section. Emissions resulting from baking, heat-curing, or heat-polymerizing as described in Section 301 of this Rule shall be excluded from determination of compliance with this section. Those portions of any similar or identical series of articles, machines, equipment, or other contrivances used for processing identically continuous web, strip, or wire, and which emit organic materials and which use operations described in this Section shall be collectively subject to compliance with this section.
304 CLEANUP: Emissions of organic materials to the atmosphere from the cleanup with photochemically reactive solvent, as defined in Section 203 of this Rule, of any article, machine, equipment, or other contrivance described in Sections 301, 302, or 303 of this Rule, shall be included with the other emissions of organic materials from that article, machine, equipment, or other contrivance for determining compliance with this Rule.
305 SOLVENT DISPOSAL: A person shall not during any one day dispose of a total of more than 1 1/2 gallons of any photochemically reactive solvent, as defined in Section 203 of this Rule, or of any material containing more than 1 1/2 gallons of photochemically reactive organic solvents, as designated in Section 203 of this Rule, by any means which will permit the evaporation of such organic solvents into the atmosphere.
306 EQUIPMENT MAINTENANCE: A person incinerating, adsorbing, or otherwise processing organic materials pursuant to this Rule shall provide, properly install, and maintain in calibration, in good working order, and in operation, devices as specified in the authority to construct or the permit to operate, or as specified by the Air Pollution Control Officer, for indicating temperatures, pressures, rates of flow, or other operating conditions necessary to determine the degree and effectiveness of air pollution control.

500 MONITORING AND RECORDS

501 RECORDS: Any person using organic solvents or any materials containing organic solvents shall supply the Air Pollution Control Officer, upon request and in the manner and form prescribed by the Officer, written evidence of the chemical composition, physical properties, and amount consumed for each organic solvent used.
502

TEST METHODS:

502.1 Absolute Vapor Pressure: Absolute vapor pressure of solvents shall be determined in accordance with ASTM Test Method D 2879-86.

502.2 Chemical Composition: The chemical composition of organic solvents shall be determined in accordance with ASTM Test Methods E 168-67, E 169-87, or E 260-85, as appropriate.

502.3 Control Efficiency: The determination of control efficiency shall be conducted in accordance with EPA Test Method 25A.
