Current through December 26, 2024

Section 250-RICR-120-05-36.16 - Exemption from Automated Parts Handling System Requirement for Solvent Cleaning Machines

A. The owner or operator of a batch vapor cleaning machine may apply for an exemption from the automated parts handling system requirement in § 36.10(C) of this Part. Exemptions shall limit solvent emissions from the cleaning machine during any three (3) month period after the compliance date to the amount calculated using Equation 4 in § 36.16(A) of this Part:

Equation 4

S = 92 * A

Where:

S = The amount of solvent, in pounds, that can be emitted from that cleaning machine during any three (3) month period after start-up.

A = The area of the solvent/air interface for that machine, in square feet.

B. Exemption requests shall be submitted to the Office of Air Resources thirty (30) days prior to startup and shall include the following information:

1. The name and address of the facility; and

2. An identification of the vapor cleaning machine for which the exemption is being requested; and

3. The area of the solvent/vapor interface, in square feet, of the vapor cleaning machine; and

4. The three (3) month emission limit, S, calculated using Equation 4 in § 36.16(A) of this Part; and

5. A statement, signed by the owner or operator of the facility, that emissions of solvent from the vapor cleaning machine will not exceed the three (3) month emission limit, S, during any three (3) month period after start-up.

C. The owner or operator of a facility which is granted an exemption to the requirements of § 36.10(C) of this Part shall maintain a log of additions and deletions of solvent from the exempted vapor cleaning machine.

D. The owner or operator of a facility which is granted an exemption to the requirements of § 36.10(C) of this Part shall demonstrate compliance with the three (3) month emission limit, S, calculated using Equation 4 in § 36.15(A) of this Part on the first (1^st) operating day of every month using the following procedure:

1. A fill-line must be marked on the machine on the first (1^st) month the measurements are taken; and

2. On the first (1^st) day of each month thereafter, the machine shall be filled to the fill-line with clean liquid solvent; and

3. On the first (1^st) day of each month, using the log of solvent additions and deletions required in § 36.16(C) of this Part, calculate solvent emissions for the most recent three (3) month period with Equation 5 in § 36.16(D)(3) of this Part:

Equation 5

EA = SA - SR

Where:

EA = solvent emissions during the three (3) month period (pounds)

SA = the total amount of solvent added to the cleaning machine during the three (3) month period (pounds)

SR = the total amount of solvent removed from the cleaning machine during the three (3) month period (pounds)

4. The cleaning machine is in compliance with the three (3) month emission limit if solvent emissions in the three (3) month period, EA, calculated using Equation 5 in § 36.16(D)(3) or this Part, are less than or equal to S, calculated according to Equation 4 in § 36.16(A) of this Part.

E. If the three (3) month emission limit, S, is exceeded two (2) times, an automated parts handling system must be installed within sixty (60) days of the end of the three (3) month period in which the second (2^nd) exceedance occurred.
