OAR 340-232-0220
Flat Wood Coating


(1)

This rule applies to all flat wood manufacturing and surface finishing facilities that manufacture the following products:

(a)

Printed interior panels made of hardwood plywood and thin particleboard;

(b)

Natural finish hardwood plywood panels; or

(c)

Hardboard paneling with Class II finishes.

(2)

This rule does not apply to the manufacture of exterior siding, tileboard, particleboard used as a furniture component, or paper or plastic laminates on wood or wood-derived substrates.

(3)

No owner or operator of a flat wood manufacturing facility subject to this rule may emit VOCs from a coating application system in excess of:

(a)

2.9 kilograms per 100 square meters of coated finished product (6.0 pounds/1,000 square feet) from printed interior panels, regardless of the number of coats applied;

(b)

5.8 kilograms per 100 square meters of coated finished product (12.0 pounds/1,000 square feet) from natural finish hardwood plywood panels, regardless of the number of coats applied; and

(c)

4.8 kilograms per 100 square meters of coated finished product (10.0 pounds/1,000 square feet) from Class II finishes on hardboard panels, regardless of the number of coats applied.

(4)

The emission limits in section (3) must be achieved by:

(a)

The application of low solvent content coating technology; or

(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 in writing by DEQ. The time period used to determine equivalency may not exceed 24 hours.

(5)

A capture system must be used in conjunction with the control devices in subsections (4)(b) and (c). The design and operation of a capture system must be consistent with good engineering practice and must provide for an overall emission reduction sufficient to meet the emission limitations in section (3).

(6)

Compliance Demonstration:

(a)

The owner or operator of a VOC source required to comply with this rule must demonstrate compliance by the methods of subsection (c), or an alternative method approved by DEQ;

(b)

A person proposing to conduct a VOC emissions test must notify DEQ of the intent to test not less than 30 days before the proposed initiation of the tests so DEQ may observe the test;

(c)

Test procedures in 40 CFR part 60, EPA Method 18, 24, or 25 must be used to determine compliance with section (3);

(d)

DEQ may accept, instead of the coating analysis required by paragraph (c)(A), a certification by the coating manufacturer of the composition of the coating, if supported by actual batch formulation records. In the event of any inconsistency between a Method 18, 24, or 25 test and a facility’s formulation data, the Method 18, 24, or 25 test will govern;

(e)

If an add-on control device is used, continuous monitors of the following parameters must be installed, periodically calibrated, and operated at all times that the associated control device is operating:

(A)

Exhaust gas temperature of all incinerators;

(B)

Temperature rise across a catalytic incinerator bed; and

(C)

Breakthrough of VOC on a carbon absorption unit.
