Section 250-RICR-120-05-36.12 - Requirements for Batch Vapor Cleaning Machine Operations without Solvent/Air InterfacesA. The owner or operator of a batch vapor cleaning machine which does not have a solvent/air interface must comply with the requirements specified below. 1. A log of solvent additions and deletions shall be maintained for each cleaning machine.2. Solvent emissions from each cleaning machine which does not have a solvent/air interface shall not exceed the amount calculated using Equation 1 in § 36.12(A)(2) of this Part: Equation 1
EL = 85.5 * (Vol)0.6
Where:
EL = the average monthly emission limit for any three (3) month period (pounds/month)
Vol = the cleaning capacity (volume) of the cleaning machine (cubic feet)
3. The owner or operator of a batch vapor cleaning machine that does not have a solvent/air interface shall demonstrate compliance with the emission limit calculated with Equation 1 in § 36.12(A)(2) of this Part on the fifteenth (15th) day of every month using the following procedure:a. A fill-line must be marked on the first month the measurements are taken. Solvent shall be added to bring the level to the same fill-line on the first (1st) operating day of each month thereafter; and b. Confirm that only clean liquid solvent is in the vapor cleaning machine; andc. Using the records of solvent additions and deletions for the previous month required in § 36.12(A)(1) of this Part and Equation 2 in § 36.12(A)(3)(c) of this Part, determine monthly solvent emissions: Equation 2
E = SA - LSR - SSR
Where:
E = the total solvent emissions for the previous month (pounds)
SA = the total amount of solvent added to the cleaning machine during the previous month (pounds)
LSR = the total amount of liquid solvent removed from the cleaning machine during the previous month (pounds)
SSR = the total amount of solid waste removed from the cleaning machine during the previous month (pounds)
d. The SSR shall be determined using either engineering calculations or 40 C.F.R. Part 60, app A-7, Method 25d, incorporated in § 36.4 of this Part.e. The average monthly emissions for the previous three (3) month period shall be calculated according to Equation 3 in § 36.12(A)(3)(e) of this Part: Equation 3

Where:
E3-month = average monthly solvent emissions during the previous three (3) month period
E1, E2, E3 = solvent emissions for each of the three (3) most recent months, calculated using Equation 2 in § 36.12(A)(3)(c) of this Part.
f. The cleaning machine is in compliance with the average monthly emission limit if E3-month, calculated using Equation 3 in § 36.12(A)(3)(e) of this Part, is less than or equal to EL, calculated according to Equation 1 in § 36.12(A)(2) of this Part.250 R.I. Code R. 250-RICR-120-05-36.12
