Rhode Island Code of Regulations › Title 250 - Department of Environmental Management › Chapter 120 - Air Resources › Subchapter 05 - Air Pollution Control › Part 36 - Control of Emissions from Organic Solvent Cleaning › Section 250-RICR-120-05-36.12 - Requirements for Batch Vapor Cleaning Machine Operations without Solvent/Air Interfaces

Current through June 14, 2024
A. 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; and
c. 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.
