Section 250-RICR-120-05-36.17 - Requirements for Industrial Cleaning Solvents

36.17.1Compliance Standards

A. The owner or operator of a source subject to § 36.17 of this Part shall limit VOC emissions from the use, handling, storage, and disposal of industrial cleaning solvents and shop towels by implementing the following work practices:

1. Store all VOC-containing industrial cleaning solvents, used shop towels and related waste materials in closed containers;

2. Ensure that mixing and storage containers used for VOC-containing industrial cleaning solvents are kept closed at all times except when depositing or removing these materials;

3. Minimize spills of VOC-containing industrial cleaning solvents and waste materials and clean up spills immediately;

4. Convey VOC-containing industrial cleaning solvents and related waste materials from one (1) location to another in closed containers or pipes;

5. Minimize VOC emissions from cleaning of storage, mixing and conveying equipment; and

6. Minimize air circulation around industrial solvent cleaning operations.

B. All spray guns must be cleaned using one (1) of the following methods:

1. A fully enclosed cleaning system that is kept closed when not in use; or

2. Flushing the spray gun without atomizing the solvent and paint residue and discharging the solvent and paint residue into a container that is kept closed when not in use; or

3. Hand cleaning of the parts of a disassembled spray gun in a container of solvent that is kept closed when not in use.

C. All spent solvent, shop towels and paint residue must be kept in an enclosed container and disposed of in accordance with applicable hazardous waste Regulations.

D. The owner or operator of a source subject to § 36.17 of this Part shall limit VOC emissions by utilizing one (1) or more of the following methods for each applicable cleaning activity:

1. Using industrial cleaning solvents with a maximum VOC content limit of fifty (50) grams VOC per liter, equivalent to forty-two one hundredths (0.42) lb/gal;

2. Using industrial cleaning solvents with a composite vapor pressure of eight (8.0) millimeters or less of mercury (mm Hg), measured at twenty degrees Celsius (20° C) (sixty-eight degrees Fahrenheit (68° F)); or

3. Using an emission control system with an overall control efficiency of at least eighty-five percent (85%).

36.17.2Recordkeeping

A. An owner or operator conducting industrial cleaning activities shall maintain monthly purchase or use records of all industrial cleaning solvents, including the following information:

1. Name and description of each industrial cleaning solvent;

2. VOC content and/or vapor pressure of each industrial cleaning solvent either as supplied or as applied;

3. Amount of each industrial cleaning solvent purchased or used;

4. Safety data sheets for each industrial cleaning solvent;

5. If applicable, documentation of control device efficiency and capture efficiency, using an applicable EPA reference method as approved by the Office of Air Resources and EPA; and

6. If applicable, date and type of maintenance performed on air pollution control equipment.

B. Any owner or operator conducting industrial solvent cleaning activities whose actual emissions before controls are less than or equal to two and seven tenths (2.7) tons of VOC for any rolling twelve (12) month period shall maintain materials purchase or use records sufficient to verify this.

C. An owner or operator conducting industrial solvent cleaning exempted by § 36.6(D) of this Part shall maintain records sufficient to verify the exemption.

D. All records required by § 36.17 of this Part shall be maintained for a minimum of five (5) years and shall be provided to the Office of Air Resources and or EPA upon request.
