Section 20-770. MISCELLANEOUS INDUSTRIAL SOLVENT CLEANING OPERATIONS

 

770.1Except as provided in § 770.9, after January 1, 2012, any person who:

 

(a)  Uses any industrial cleaning solvent in a solvent cleaning operation in or on the premises of a factory or a shop as part of a manufacturing, production, or repairing process where the facility emits at least fifteen pounds (15 lb.) of VOC emissions in any one (1) day from all solvent cleaning operations shall be subject to this section through § 770.10(a);

 

(b) Sells, supplies, offers for sale, or manufactures any industrial cleaning solvent for use in the District of Columbia shall be subject to this section through § 770.10(a); or 

 

(c)Uses any industrial cleaning solvent in a solvent cleaning operation in or on the premises of a factory or a shop as part of a manufacturing, production, or repairing process where the facility emits less than fifteen pounds (15 lb.) of VOC emissions in any one (1) day from all solvent cleaning operations shall be subject to § 770.10(b).

 

770.2Any solvent cleaning operation that becomes or is currently subject to the provisions of this section by exceeding the applicability threshold in § 770.1(a) will remain subject to these provisions even if its throughput or emissions have fallen or later fall below the applicability threshold.

 

770.3For purposes of § 770 and any of the definitions in § 799 applicable to § 770, the District incorporates by reference rules and test methods from the California Air Resource Board (CARB), the South Coast Air Quality Management District (SCAQMD), and the American Society for Testing and Materials (ASTM), where specifically cited. 

 

770.4Each part of § 770 shall be deemed severable, and if any part is held to be invalid, the remainder shall continue in full force.

 

770.5On and after January 1, 2012, no person may use any industrial cleaning solvent in a solvent cleaning operation unless: 

 

(a) The person uses an industrial cleaning solvent that meets at least one of the following limitations:

 

(1)A content limit of fifty grams (50 g.) VOC per liter as applied including water and exempt compounds; or

 

(2)A composite vapor pressure of less than or equal to eight millimeters of mercury (8 mm. Hg) at twenty degrees Celsius (20° C) or sixty-eight degrees Fahrenheit (68° F); or

 

(b) The person controls VOC emissions from the solvent cleaning operation with an emission control system with an overall control efficiency of at least eight-five percent (85%).

 

770.6The VOC content of industrial cleaning solvents shall be determined by:

 

(a) EPA Reference Method 24 (Code of Federal Regulations, Title 40, Part 60, Appendix A), where the exempt compounds' content shall be determined by the South Coast Air Quality Management District's (SCAQMD) Method 303 (Determination of Exempt Compounds) contained in the SCAQMD "Laboratory Methods of Analysis for Enforcement Samples" manual; or

 

(b)SCAQMD Method 304 [Determination of Volatile Organic Compounds (VOC) in Various Materials] contained in the SCAQMD "Laboratory Methods of Analysis for Enforcement Samples" manual; and

 

(c) For the purposes of (a) and (b), exempt perfluorocarbon compounds will be analyzed as exempt compounds for compliance with § 770.4, only when manufacturers specify which individual compounds are used in the solvent formulation and identify the EPA and the District approved test methods used to quantify the amount of each exempt compound.

 

770.7The vapor pressure of the industrial cleaning solvent shall be determined using the following methods:

 

(a) If the solvent subject to § 770.5 is composed of only one (1) VOC, the vapor pressure shall be determined by ASTM Method D-2879-86 or from a published source such as: Boublik, T., V. Fried and E. Hala, “The Vapor Pressure of Pure Substances,” Elsevier Scientific Publishing Company, New York (1973), or Perry’s Chemical Engineer’s Handbook, McGraw-Hill Book Company (1984), or CRC Handbook of Chemistry and Physics, Chemical Rubber Publishing Company (1986-87), or Lange’s Handbook of Chemistry, John A. Dean, editor, McGraw-Hill Book Company (1985);

 

(b) If the industrial cleaning solvent subject to § 770.5 is composed of VOCs and non-VOCs, the vapor pressure shall be determined by the following equation:

 

P =  

 

where:

 

P = Total vapor pressure of the VOC component of the solvent at twenty degrees Celsius (20° C) or sixty-eight degrees Fahrenheit (68º F), in millimeters of mercury (mm. Hg),

 

n = Number of VOCs in the solvent,

 

i = Subscript denoting an individual VOC,

 

Pi = Vapor pressure of the “i”th VOC at twenty degrees Celsius (20° C) or sixty-eight degrees Fahrenheit (68º F) determined pursuant to § 709.8(a), in mm Hg, and

 

Xi = Mole fraction of the “i”th VOC of the total solvent; or

 

(c) If the industrial cleaning solvent subject to § 770.5 is composed of only VOCs, the vapor pressure shall be determined by ASTM Method D-2879-86 or by the equation in § 770.7(b).

 

770.8A person who sells or offers for sale any solvent containing VOCs for use in a solvent cleaning operation shall provide the following written information to the purchaser:

 

(a)The name and address of the solvent supplier;

 

(b)The type of solvent including the product or vendor identification number; and

 

(c)The vapor pressure of the solvent measured in millimeters of mercury (mm. Hg) at twenty degrees Celsius (20o C) or sixty-eight degrees Fahrenheit (68° F); or

 

(d)The VOC content in grams per liter including exempt compounds.

 

770.9Subsections 770.1 through 770.8 shall not apply on or after January 1, 2012, to any person who owns, operates, or leases:

 

(a)Any cold cleaning machine, batch vapor cleaning machine, in-line vapor cleaning machine, airless cleaning machine, air-tight cleaning machine, or other solvent cleaning machine subject to §§ 763 to 769;
