RULE 1136. WOOD PRODUCTS COATINGS

(a) Purpose and Applicability
The purpose of Rule 1136 is to reduce volatile organic compounds (VOC) emissions from the application of coatings or strippers to, and surface preparation of, any wood products, including furniture, cabinets, shutters, frames and toys. This rule shall not apply to residential noncommercial operations.

(b) Definitions
For the purposes of this rule, the following definitions shall apply:

  1. AEROSOL COATING PRODUCT means a pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application.
  2. BARRIER COAT - PLASTIC COMPONENTS is a coating applied to simulated wood components made from polypropylene, polystyrene, polyester, polyurethane, and other plastics to improve adhesion of waterborne coatings.
  3. BINDERS are non-volatile polymeric organic materials (resins) which form the surface film in coating applications.
  4. CAPTURE EFFICIENCY, in percent, is the ratio of the weight of the VOC in the effluent stream entering the control device to the weight of VOC emitted from wood product coating operations, both measured simultaneously, and can be calculated by the following equation:
  5. Capture Efficiency = [Wc/We] x 100
    Where:
              Wc = weight of VOC entering control device
              We = weight of VOC emitted

  6. CLASSIC GUITARS are replicas of guitars that were originally manufactured before 1965 and are manufactured by the same original processes.
  7. CLEAR SEALER is a coating containing binders, but not opaque pigments, which seals the wood product prior to application of the subsequent coatings.
  8. CLEAR TOPCOAT is a final coating which contains binders, but not opaque pigments, and is specifically formulated to form a transparent or translucent solid protective film.
  9. COATING is a material which is applied to a surface and which forms a film in order to beautify and/or protect such surface.
  10. COMPOSITE WOOD is a manufactured material consisting of tightly compressed wood fibers bonded with resins which includes, but is not limited to, particleboard, fiberboard and hardboard.
  11. COMPOSITE WOOD EDGE FILLER is a material which is applied to the edge of a composite wood product, and whose primary function is to build up, or fill the voids and imperfections on the edge of the composite wood product.
  12. CONTROL DEVICE EFFICIENCY, in percent, is the ratio of the weight of the VOC removed by the control device from the effluent stream entering the control device to the weight of VOC in the effluent stream entering the control device, both measured simultaneously, and can be calculated by the following equation:
  13. Control Device Efficiency = [(Wc-Wa)/Wc] x 100
    Where:
              Wc = weight of VOC entering control device
              Wa = weight of VOC discharged from the control device

  14. CONVENTIONAL AIR SPRAY means a spray coating method in which the coating is atomized by mixing it with compressed air at an air pressure greater than 10 pounds per square inch (gauge) at the point of atomization. Airless and air assisted airless spray technologies are not conventional air spray because the coating is not atomized by mixing it with compressed air. Electrostatic spray technology is also not considered conventional air spray because an electrostatic charge is employed to attract the coating to the workpiece.

calibrated in a manner approved by the Executive Officer and maintained in
optimum working order.

(h) Rule 442 ApplicabilityAny coating, coating operation, or facility which
is exempt from all or a portion of the VOC limits of this rule shall comply
with the provisions of Rule 442 unless compliance with the limits specified
in this rule is achieved.

(i) Alternative Emission Control Plan An owner or operator may achieve
compliance with paragraph (c)(1) by means of an Alternative Emission
Control Plan pursuant to Rule 108.

(j) Emissions Averaging Provisions

(1) Owners or operators may comply with the provisions of subparagraph
(c)(1)(A) by using an averaging approach, provided all requirements of this
subdivision are met. The owner or operator shall demonstrate that actual
emissions from the coatings being averaged are less than or equal to 90
percent of the allowable emissions, on a daily basis, using the following
inequality:

Where: VOCi = VOC content limit of coating "i" (kilograms (kg) of VOC/liter
of material for low solids stains; and kg VOC/kg solids for all other
coatings), as required by subparagraph (c)(1)(A);

Ui = Usage of coating "i" (liters of material for low-solids stains; and kg
of solids for all other coatings);

andERi = Actual VOC content of coating "i", as applied (kg of VOC/liter of
material for low-solids stains; and kg VOC/kg solids for all other
coatings).

(2) The emission averaging is limited to any combination of stains,
sealers, clear topcoats, and pigmented coatings selected by the owners or
operators. Any wood product coating not included in the emission averaging
shall comply with the VOC limits in subparagraph (c)(1)(A).

(3) Emissions Averaging Plan (Plan)Owners or operators using the averaging
approach shall submit a Plan, pursuant to Rule 221 - Plans, to the
Executive Officer and USEPA. The applicant must receive approval of the
Plan in writing from the Executive Officer and USEPA prior to
implementation. Submittal of the Plan does not provide an exemption from
the rule requirements. The owner or operator shall resubmit, on an annual
basis, a Plan for approval by the AQMD. The Plan shall include, at a
minimum:

(A) A description of the wood product coatings to be included in the
averaging program; and

(B) A description of the quantification and recordkeeping procedures for
coating usage; coating VOC and solids content; VOC emissions; and
calculations to show daily compliance with paragraph (j)(1).

(k) Exemptions

(1) The provisions of paragraphs (c)(1) and (c)(2) of this rule shall not
apply to facilities that use less than one gallon per day of coating, as
applied, subject to this rule.

(2) The provisions of this rule shall not apply to coating operations
subject to, and in compliance with, the provisions of Rule 1104.

(3) The provisions of subparagraphs (c)(1)(A) and (C) shall not apply to
the manufacturing of classic guitars until July 1, 1996.

(4) Refinishing, Replacement, and Custom Replica Furniture Operations:
Until July 1, 1996, the provisions of subparagraphs (c)(1)(A) and (C) shall
not apply to any refinishing operations necessary for preservation, to
return the wood product to original condition, to replace missing furniture
to produce a matching set, or to produce custom replica furniture, provided
records are maintained daily for two years as to the amount, type and VOC
content of each coating used.

(5) The provisions of paragraph (c)(1) shall not apply to touch-up and
repair coatings until July 1, 1996.

(6) The provisions of this rule shall not apply to aerosol coating
products.

(7) The provisions of subparagraph (c)(1)(A) that are effective on and
after September 1, 1995 shall not apply until July 1, 1996 to clear
topcoats, pigmented coatings and sealers applied to architectural millwork
goods, provided that the coatings comply with the pre-September 1, 1995 VOC
limits.

(8) Notwithstanding the requirements of Rule 109(c)(1), Recordkeeping for
Volatile Organic Compound Emissions, any facility that switches to
waterborne coatings that meet the July 1, 1996 VOC limits may request
written approval from the Executive Officer to record data on up to a
quarterly basis, provided the Executive Officer determines that such
recordkeeping allows for an equivalent level of enforceability.

(9) The provisions of subparagraph (c)(2) shall not apply to any facility
which obtains written approval from the Executive Officer and that is using
coatings that have a lower VOC content than the July 1, 1996 VOC limits
provided that following inequality is satisfied:
