PERMANENT RULES

SPOKANE REGIONAL

CLEAN AIR AGENCY

[Filed May 12, 2021, 2:55 p.m., effective June 21, 2021]

Effective Date of Rule: June 21, 2021.

Purpose: Amend Spokane Regional Clean Air Agency (SRCAA) Regulation I, Article VI, Section 6.13; and Article X, Section 10.08. The amendments clarify requirements, align the twenty-five year old surface coating regulation with the federal regulations adopted in 2008 and local new source review (NSR) regulations adopted in July 2020. The amendments will close the loop with the NSR regulations by including a low usage threshold in the surface coating regulation. Small, low usage operations below the threshold will be exempt from enclosure and control requirements, reducing the regulatory burden for the small business and help to conserve agency resources by focusing on sources with the potential to have increased emissions or nuisance concerns. The amendments will not change fees or add new requirements for businesses to meet.

Citation of Rules Affected by this Order: Amending SRCAA Regulation I, Article VI, Section 6.13; and Article X, Section 10.08.

Statutory Authority for Adoption: RCW 70A.15.2040.

(A) Purpose. SRCAA Regulation I, Article VI, Section 6.13 establishes controls on surface coating operations in Spokane County ((in order))to:

(1) Reduce particulate emissions from coating overspray;

(2) Reduce public exposure to Toxic Air Pollutants as listed in Chapter 173-460 WAC;

(3) Reduce emissions of precursors to the formation of tropospheric ozone and other photochemical oxidants; and

(4) Encourage pollution prevention.

(B) Applicability. Section 6.13 applies to all commercial surface coating operations in Spokane County. Section 6.13 includes all surface preparation, surface coating, cleanup, and disposal associated with ((general))commercial surface coating operations in Spokane County, unless specifically exempted.

(C) Definitions. Unless a different meaning is clearly required by context, words, and phrases used in Section 6.13, the following definitions apply to Section 6.13:((shall have the following meaning:))

(1) Airless Spray means a spraying system that uses hydraulic atomization instead of air atomization. The coating is supplied to the gun under high fluid pressure between 1,000 and 3,000 psig and the coating is forced through a small orifice.

(2) Air-Assisted Airless Spray means a spraying system that combines air and airless features. An airless type fluid tip atomizes the paint and shapes the fan pattern at fluid pressures between 300 and 1,000 psig. Lower pressure air from 10 to 30 psig combines at the spray cap to adjust the fan shape to eliminate heavy edges (tails).

(3) Automated means the technique, method, or system of operating or controlling a process by mechanical, electrical, hydraulic, or electronic means independent of human intervention.

(4) Brush Coat Application means manual application of coatings by use of a paint brush.

(5) Coating means a material or formulation of materials that is applied to or impregnated into a surface in order to beautify, protect, enhance the function, or otherwise cover the surface.

(((6)))(7)Container means the individual receptacle that holds a coating or coating component for storage and distribution.

(((7)))(8)Dip Coat Application means application of coatings in which the surface to be coated is immersed in a solution (or dispersion) containing the coating material and withdrawn.

(((13)))(16)Multi-Coat System means a coating system where more than one product or coat is sequentially applied to the same surface and generally consists of a pigmented base coat, one or more semi-transparent mid-coats, and a transparent clear coat. The VOC content for a multi-coat system shall be calculated as follows:

where:

VOCTM is the average sum of the VOC content, as applied to the surface, in a multi-coat system; ((and))

VOCBC is the VOC content, as applied to the surface, of the base coat; ((and))

(((16)))(22)Reducer means any solvent added to a coating which has the effect of reducing the viscosity of the coating or shortening the drying time.

(((17)))(23)Refinishing means reapplying coating to a surface to repair, restore, or alter the finish.

(((19)))(25)Solvent Consumption means the volume of solvent purchased or otherwise procured, less the volume recycled or disposed. In the absence of records which document the transfer of solvent to an authorized recycler or waste hauler, solvent consumption means the volume of solvent purchased or otherwise procured.

(((20)))(27)Standard Engineering Practices means that accepted, peer reviewed sets of criteria are used in designing equipment (i.e. Uniform Building, Electrical, and Fire Codes, recommendations of the American Conference of Governmental Industrial Hygienists, guidelines of the Department of Labor and Industry, etc.).

(((21)))(28)Surface Coating means the application of coating to a surface.

(11) Inside exhaust exemption. If the Department of Labor & Industries or another agency of jurisdiction determines that the emissions from a surface coating operation to an inside work area are below the threshold where an exhaust system is required and the Fire Department or District of jurisdiction has no objection, then the Control Officer may grant an exemption to Section 6.13 (E)(1).))
