Rhode Island Code of Regulations › Title 250 - Department of Environmental Management › Chapter 120 - Air Resources › Subchapter 05 - Air Pollution Control › Part 15 - Air Pollution Control Regulation No. 15 - Control of Organic Solvent Emissions › Section 250-RICR-120-05-15.7 - Emission Limitations

Current through June 14, 2024
A. Any facility
				  which h as or ever has had potential emissions of VOC of fifty (50) tons/year
				  or more, as defined in Part 0 of this Subchapter (General Definitions), from
				  equipment not specifically controlled by any other VOC regulation, shall
				  install and operate in compliance with RACT, as specified in an enforceable
				  document issued by the Director.
B.
				  Facilities using add on controls to comply with RACT must show that the
				  equipment meets specific capture and control performance standards which will
				  be set in an enforceable document. Control efficiency of the equipment will be
				  determined using EPA-approved test methods. Calculations will be done on a
				  solids basis. Continuous compliance will be maintained at all times. Compliance
				  averaging times will be met according to the control device chosen and EPA test
				  methods (as codified in 40
				  C.F.R. §
											60, Appendix A), incorporated
				  in §
										15.4 of this Part, as
				  follows:
Compliance Method
EPA Reference Test Method
Test Averaging Time
Reformulation
24
Instantaneous
Solvent destruction or solvent recovery except
								  carbon adsorption
25
3 hours
Carbon adsorption
25 or other test method as appropriate
7-day rolling average
C.
				  Or other methods approved by the Director and EPA. Once the control efficiency
				  has been determined for any add-on control device by Reference Method 25, or
				  any alternative method approved by the Department and EPA, compliance shall be
				  determined on an instantaneous basis (e.g. determined control efficiency shall
				  be used to calculate whether samples from the process meet the applicable
				  emissions limit.)
D. The owner or
				  operator of a facility using carbon adsorption as a control measure shall
				  obtain data on daily solvent usage and solvent recovery and determine the
				  solvent recovery efficiency of the system every day. The recovery efficiency
				  for each day shall be computed as the ratio of the total recovered solvent for
				  that day and the prior six (6) consecutive operating days to the total solvent
				  usage for the same seven-day period. This ratio shall be expressed as a
				  percentage. Facilities may apply to the Director for an alternative averaging
				  time if meeting the emission limitation as a seven-day rolling average is not
				  technically or economically feasible. In no event shall the averaging period
				  exceed a 30-day rolling period. All alternative averaging periods must be
				  consistent with EPA guidance.
E.
				  Every two (2) years, a facility may be required to undergo RACT review at the
				  discretion of the Department.
F.
				  Any facility which is subject to the requirements of §
										15.7(A) of
				  this Part, but has not been required to install and operate in compliance with
				  RACT shall, within six (6) months after becoming a fifty (50) ton per year
				  potential VOC source, submit to the Director a RACT proposal for approval which
				  includes all information specified in §
										15.7(G) of
				  this Part.
G. All RACT proposals
				  submitted to comply with §
										15.7(F) of
				  this Part shall include the following information:
1. An inventory of all VOC-emitting equipment
				  at the facility;
2. An inventory of
				  all VOC-emitting equipment at the facility not exempted from the RACT
				  requirement of this section according to §
											15.6(B) of
				  this Part;
3. Identification of any
				  additional VOC-emitting activities at the facility;
4. The maximum capacity of each piece of
				  VOC-emitting equipment not exempted under §
											15.6(B) of
				  this Part;
5. The actual maximum
				  amount of VOC emitted each in any day from each piece of VOC-emitting equipment
				  at the facility not exempted under §15. 6(B) of this Part;
6. An examination of the technical and
				  economic feasibility of installing addon VOC control equipment to control
				  emissions from each piece of VOC equipment not exempted under §
											15.6(B) of
				  this Part;
7. An examination of the
				  technical and economic feasibility of reducing VOC use in each piece of
				  equipment not exempted under §
											15.6(B) of
				  this Part and in any additional VOC-emitting activities at the
				  facility;
8. An examination of the
				  technical and economic feasibility of using different process equipment or
				  different processes to reduce VOC use or emissions not exempted under §
											15.6(B) of
				  this Part;
9. The control option or
				  combination of control options selected, including emission limits and the test
				  methods to demonstrate compliance;
10. The amount of reduction in VOC emissions
				  that will be associated with implementing the selected control
				  option;
11. A schedule for
				  implementation, including a demonstration of compliance;
12. A means of assessing continuous
				  compliance, including test methods, monitoring devices and reporting
				  requirements;
13. A description of
				  future research that will be conducted by the owner or operator to further
				  reduce VOC emissions beyond the level of emissions proposed; and
14. Any additional information requested by
				  the Director that is deemed necessary to determine RACT.
