Current through Register Vol. 63, No. 3, March 1, 2024
(1) No person may
operate a coating line which emits into the atmosphere VOCs in excess of the
limits in section (5), expressed as pounds VOC per gallon of coating applied,
excluding water and exempt solvents, unless an alternative emission limit is
approved by DEQ pursuant to section (3) or emissions are controlled to an
equivalent level pursuant to section (7).
(2) Exemptions:
(a) This rule does not apply to airplanes
painted out of doors in open air; automobile and truck refinishing; customized
top coating of automobiles and trucks, if production is less than 35 vehicles
per day; marine vessels and vessel parts painted out in the open air; flat wood
coating; wood furniture and wood cabinets; wooden doors, mouldings, and window
frames; machine staining of exterior wood siding; high temperature coatings
(for service above 500° F.); lumber marking coatings; potable water tank
inside coatings; high performance inorganic zinc coatings, air dried, applied
to fabricated steel; and markings by stencil for railroad cars;
(b) This rule does not apply to:
(A) Sources whose VOC potential to emit
before add on controls from activities identified in section (5) are less than
10 tons per year (or 3 pounds VOC/hour or 15 pounds actual VOC/day);
or
(B) Sources used exclusively for
chemical or physical analysis or determination of product quality and
commercial acceptance, such as research facilities, pilot plant operations, and
laboratories, unless:
(i) The operation of
the source is an integral part of the production process; or
(ii) The emissions from the source exceed 363
kilograms (800 pounds) in any calendar month.
(3) Exceptions:
(a) On a case-by-case basis, DEQ may approve
exceptions to the emission limits specified in section (5), upon documentation
by the source that an alternative emission limit would satisfy the federal
criteria for RACT;
(b) Included in
this documentation must be a complete analysis of technical and economic
factors which:
(A) Prevent the source from
using both compliance coatings and pollution control devices; and
(B) Justify the alternative emission limit
sought by the source.
(c)
The alternative emission limit approved by DEQ will be incorporated into the
source's Air Contaminant Discharge Permit, or Title V operating permit, and
will be effective upon approval by EPA as a source specific SIP
revision.
(4)
Applicability: This rule applies to each coating line, which includes the
application area, flashoff area, air and forced air dryer, and oven used in the
surface coating of the parts and products in subsections (5)(a) through
(j).
(5) Process and Limitation:
These emission limitations must be based on a daily average except subsection
(5)(e) must be based on a monthly average. If more than one emission limitation
in this rule applies to a specific coating, then the most stringent emission
limitation must be applied:
(a) Can Coating:
(A) Sheet basecoat, exterior and interior,
and over-varnish; two-piece can exterior, basecoat and over-varnish, 2.8
pounds/gallon;
(B) Two- and
three-piece can interior and exterior body spray, two-piece can exterior end,
spray or roll coat, 4.2 pounds/gallon;
(C) Three-piece can side-seam spray 5.5
pounds/gallon;
(D) End sealing
compound 3.7 pounds/gallon;
(E) End
Sealing Compound for fatty foods 3.7 pounds/gallon.
(b) Fabric Coating 2.9
pounds/gallon;
(c) Vinyl Coating
3.8 pounds/gallon;
(d) Paper
Coating 2.9 pounds/gallon;
(e)
Existing Coating of Paper and Film in the Medford-Ashland AQMA 55 pounds VOC
per 1000 square yards of material per pass;
(f) Auto and Light Duty Truck Coating:
(A) Prime 1.9 pounds/gallon;
(B) Topcoat 2.8 pounds/gallon;
(C) Repair 4.8 pounds/gallon;
(g) Metal Furniture Coating 3.0
pounds/gallon;
(h) Magnet Wire
Coating 1.7 pounds/gallon;
(i)
Large Appliance Coating 2.8 pounds/gallon;
(j) Miscellaneous Metal Parts and Products:
(A) Clear Coatings 4.3
pounds/gallon;
(B) Forced Air Dried
or Air Dried 3.5 pounds/gallon;
(C)
Extreme Performance Coatings 3.5 pounds/gallon;
(D) Other Coatings, i.e., powder, oven dried,
3.0 pounds/gallon;
(E) High
Performance Architectural Coatings 3.5 pounds/gallon.
(6) Compliance Determination:
Compliance with this rule must be determined by testing in accordance with 40
CFR part 60 EPA Method 18, 24, 25, a material balance method, or an equivalent
plant specific method approved by and on file with DEQ. The limit in section
(1) of VOC in the coating is based upon an assumed solvent density, and other
assumptions unique to a coating line; where conditions differ, such as a
different solvent density, a plant specific limit developed pursuant to the
applicable Control Technology Guideline document may be submitted to DEQ for
approval.
(7) Reduction Method:
Compliance with the emission limits of sections (3) and (5) must be achieved
by:
(a) The application of low solvent
content coating technology;
(b) An
incineration system which oxidizes at least 90.0 percent of the non methane
VOCs entering the incinerator, VOC measured as total combustible carbon, to
carbon dioxide and water; or
(c) An
equivalent means of VOC removal. The equivalent means must be approved by DEQ
and will be incorporated in the source's Air Contaminant Discharge Permit or
Title V Permit, and will be effective upon approval by EPA as a source-specific
SIP revision. Other alternative emission controls approved by DEQ and allowed
by EPA may be used to provide an equivalent means of VOC removal.
(8) Recordkeeping Requirements:
(a) A current list of coatings must be
maintained which provides all the coating data necessary to evaluate
compliance, including the following information, where applicable:
(A) Coating catalyst and reducer
used;
(B) Mix ratio of components
used;
(C) VOC content of coating as
applied; and
(D) Oven
temperature.
(b) Where
applicable, a monthly record must be maintained indicating the type and amount
of solvent used for cleanup and surface preparation;
(c) Such records must be retained and
available for inspection by DEQ for a period of five years.

Act Implementation Plan that EQC adopted under OAR 340-200-0040.]
