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-120-05-36.8 - General Requirements for Solvent Cleaning Machines

Current through June 14, 2024
A.
				  Equipment covers and dipping or rotating baskets must be constructed of
				  nonporous or nonabsorbent material. Covers must form a tight seal with the
				  sides of the solvent cleaning machine and have no gaps or holes.
B. When the solvent cleaning machine cover is
				  open, drafts at the same elevation as the tank lip must not be greater than
				  forty (40) m/min. (one hundred thirty (130) ft/min.) when measured one to two
				  (1 to 2) meters (three to seven (3 to 7) feet) upwind.
C. Leaks must be repaired immediately or the
				  solvent cleaning unit must be shut down.
D. Equipment used in solvent cleaning must
				  display a conspicuous summary of proper operating procedures consistent with
				  minimizing emissions of organic solvents.
E. Any solvent spray must be a solid, fluid
				  stream, which is delivered at a pressure no greater than ten (10) pounds per
				  square inch (psi) and which does not cause excessive splashing. For purposes of
				  this regulation, no solvent spray shall be an atomized or shower
				  spray.
F. Spills shall be wiped up
				  immediately. The wipe rags shall be stored in covered containers meeting the
				  specifications in §
										36.8(L) of
				  this Part.
G. No porous or
				  absorbent materials, such as sponges, fabrics, wood, or paper products, shall
				  be placed in an organic cleaning machine.
H. Parts baskets or parts shall be drained
				  under the cover and shall not be removed from the cleaning machine for at least
				  fifteen (15) seconds or until dripping ceases and the pieces are visually dry,
				  whichever is longer.
I. Parts
				  having cavities or blind holes shall be tipped or rotated while draining before
				  being removed from the vapor zone and shall be oriented for best
				  drainage.
J. All parts shall be
				  oriented for best drainage.
K. When
				  solvent is added to or drained from a solvent cleaning machine, the solvent
				  shall be transferred using threaded or other leakproof couplings and the end of
				  the pipe in the solvent sump shall be located beneath the liquid solvent
				  surface.
L. Solvent, waste solvent,
				  still bottoms, and sump bottoms must be stored in covered containers and waste
				  solvent transferal or disposal must allow less than twenty percent (20%) of the
				  waste solvent (by weight) to evaporate into the atmosphere. The closed
				  containers may contain a device that allows for pressure relief, providing that
				  the device does not allow liquid solvent to drain from the
				  containers.
M. Each solvent
				  cleaning machine and related air pollution control equipment shall be
				  maintained as recommended by the manufacturer of the equipment.
N. Operators must receive training in proper
				  solvent cleaning procedures and, if requested by representatives of the
				  Department or the EPA during an inspection, must complete and pass the
				  applicable sections of the test on those procedures in 40 C.F.R. Part 63, app A
				  to Subpart T incorporated in §
										36.4 of this
				  Part.
O. No work area fans shall be
				  located and positioned so that they blow across the opening of a solvent
				  cleaning machine.
P. No solvent
				  cleaning machine shall be located and positioned so that ventilation from an
				  open window blows across the opening of the solvent cleaning machine.
Q. Facility wide emissions of Hazardous Air
				  Pollutants (HAPs) from organic solvent cleaning operations shall not exceed one
				  thousand five hundred (1,500) pounds of any one (1) HAP or four thousand
				  (4,000) pounds of any combination of HAPs per calendar month, based upon a
				  twelve (12) month rolling average unless a greater quantity of HAP emissions is
				  allowed by an operating permit issued pursuant to Part 29 of this Subchapter,
				  Air Pollution Control Regulation No. 29 -Operating Permits. In no case shall
				  emissions exceed the facility wide emission limits specified in
				  40 C.F.R. §
											63.471, incorporated in §
										36.4 of this
				  Part.
