Rule 3.20 WOOD PRODUCTS COATING OPERATIONS (Adopted 12/05/2005)

A. GENERAL 

A.1. PURPOSE: To establish limits on the emission of volatile 

organic compounds (VOC) from coatings and strippers used on 

wood products and from products used in surface preparation 

and cleanup. 

A.2. APPLICABILITY: This rule applies to any person who uses, 

manufactures, blends, sells, repackages, distributes, or 

specifies the use of wood products coatings, and/or 

strippers for use within the District. 

A.3. SEVERABILITY: If a court of competent jurisdiction issues 

an order that any provision of this Rule is invalid, it is 

the intent of the District that other provisions of this 

Rule remain in full force and effect, to the extent allowed 

by law. 

B. EXEMPTIONS 

The provisions of this Rule shall not apply to the following: 

B.1. This rule does not apply to sources using less than 55 

gallons per year (singly or in any combination) of wood 

products coatings and/or strippers. 

B.2. Wood products coatings that are sold in non-refillable 

aerosol-spray containers. 

B.3. Coating operations for the purpose of manufacturing a 

finished wood panel intended for attachment to the inside 

walls of buildings including, but not limited to, homes and 

office buildings, mobile homes, trailers, prefabricated 

buildings and similar structures; or a finished exterior 

wood siding intended for use in construction. 

B.4. Coating of architectural components or structures not 

coated in a shop environment. Coating of architectural 

components or structures is subject to the provisions of 

Rule 3.15 Architectural Coatings.

defined in Rule 10.1. 

C.3. Binders: Non-volatile polymeric organic materials (resins) 

that form the surface film in coating applications. 

C.4. Capture Efficiency: Expressed in percent, capture 

efficiency is the ratio of the weight of the VOC in the 

effluent stream entering a control device to the weight of 

the VOC emitted from wood product coating operations, both 

measured simultaneously, and can be calculated by the 

following equation: 

Where: Wc = Weight of VOC entering the control device 

We = Weight of VOC emitted 

C.5. Cleanup Material: A VOC-containing material used to clean 

application equipment used in wood products coating 

operations.

cover meets with the main body of the container without any 

gaps between the cover and the main body of the container. 

C.8. Coating: A material applied onto or impregnated into a 

substrate for protective, decorative, or functional 

purposes. Such materials include, but are not limited to 

paints, varnishes, sealers, and stains. 

C.9. Control Efficiency: Expressed in percent, control 

efficiency 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. 

Control efficiency is calculated by the following equation:
