California Code of Regulations › Title 17 - Public Health › Division 3 - Air Resources › Chapter 1 - Air Resources Board › Subchapter 7.5 - Airborne Toxic Control Measures › Section 93109 - Airborne Toxic Control Measure for Emissions of Perchloroethylene from Dry Cleaning and Water-Repelling Operations

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Purpose.
The purpose of this control measure is to phase-out the use
					 of perchloroethylene (Perc) from dry cleaning and water-repelling operations.
					 Eliminating these emissions will further protect the public health, especially
					 for Californians who live or work near dry cleaning and water-repelling
					 facilities.
(b)
				  Applicability.
This section applies to any person who sells or distributes
					 Perc to California dry cleaners or who sells, distributes, installs, owns, or
					 operates dry cleaning equipment in California that uses any solvent that
					 contains Perc.
(c)
				  Severability.
Each part of this section is deemed severable, and in the
					 event that part of this section is held to be invalid, the remainder of this
					 section shall continue in full force and effect.
(d) Definitions. The definitions in Health
				  and Safety Code division 26, part 1, chapter 2, commencing with section
				  39010, shall apply, with the
				  following additions:
(1)
"Add-on
				  secondary control machine"
means a closed-loop machine with a
				  secondary control system that is designed or offered as a separate retrofit
				  system for use on multiple machine makes and models.
(2)
"Adsorptive cartridge
				  filter"
means a replaceable cartridge filter that contains
				  diatomaceous earth or activated clay as the filter medium.
(3)
"Carbon adsorber"
means
				  an air cleaning device that consists of an inlet for exhaust gases from a dry
				  cleaning machine; activated carbon in the form of a fixed bed, cartridge, or
				  canister, as an adsorbent; an outlet for exhaust gases; and a system to
				  regenerate or reclaim saturated adsorbent.
(4)
"Cartridge filter"
means
				  a replaceable cartridge filter that contains one of the following as the filter
				  medium: paper, activated carbon, or paper and activated carbon. A cartridge
				  filter contains no diatomaceous earth or activated clay. Cartridge filters
				  include, but are not limited to: standard filters, split filters, "jumbo"
				  filters, and all carbon polishing filters.
(5)
"Closed-loop machine"
means dry cleaning equipment in which washing, extraction, and drying are all
				  performed in the same single unit (also known as dry-to-dry) and which
				  recirculates Perc-laden vapor through a primary control system with or without
				  a secondary control system with no exhaust to the atmosphere during the drying
				  cycle. A closed-loop machine may allow for venting to the ambient air through a
				  fugitive control system after the drying cycle is complete and only while the
				  machine door is open. A closed-loop machine includes a primary control machine,
				  an add-on secondary control machine, or an integral secondary control
				  machine.
(6)
"Co-residential"
means sharing a common wall, floor, or
				  ceiling with a residence or located within the same building.
(7)
"Contact information"
means name, mailing address, facility location, phone number, and if
				  applicable, email address and fax number.
(8)
"Converted machine"
means an existing vented machine that has been modified to be a closed-loop
				  machine by eliminating the aeration step, installing a primary control system,
				  and providing for recirculation of the Perc-laden vapor with no exhaust to the
				  atmosphere or workroom during the drying cycle. A converted machine may allow
				  for venting to the ambient air through a fugitive control system after the
				  drying cycle is complete and only while the machine door is open.
(9)
"Cool-down"
means the
				  portion of the drying cycle that begins when the heating mechanism deactivates
				  and the refrigerated condenser continues to reduce the temperature of the air
				  recirculating through the drum to reduce the concentration of Perc in the
				  drum.
(10)
"Desorption"
means regeneration of an activated carbon bed, or
				  any other type of vapor adsorber by removal of the adsorbed solvent using hot
				  air, steam, or other means.
(11)
"Dip tank operations"
means the immersion of materials in a
				  solution that contains Perc, for purposes other than dry cleaning, in a tank or
