SECTION 6.14 STANDARDS FOR CONTROL OF PARTICULATE MATTER ON PAVED SURFACES

     A. Applicability. The provisions of Section 6.14 shall apply to any government agency of a state, county, city or ((local government or private company)) municipal corporation that applies or contracts for application of sanding materials to or mechanically sweeps or vacuums or contracts for sweeping or vacuuming of paved surfaces within the PM10 Nonattainment area, or within the PM10 maintenance area after the nonattainment area is redesignated to attainment. This Section shall also apply to all suppliers of sanding materials to be used by these affected entities.

     B. Definitions.

     1. Affected Entit((ies))y ((are)) is any governmental agency of a state, county, city or ((local government or private company)) municipal corporation as described in Subsection A. ((that applies sanding material to, or mechanically sweeps or vacuums paved surfaces within the PM10 Nonattainment area.))

     2. Approved Laboratory means a certified or approved facility capable of performing the specified tests in a competent, professional, and unbiased manner in accordance with ASTM testing procedures.

     3. The Authority is the Spokane County Air Pollution Control Authority.

     4. Base Sanding Amount is the average amount of sanding materials applied per lane mile by each affected entity within the PM10 Nonattainment Area during the 1992 - 1993 season or another base season, as requested by an affected entity and approved by the Authority.

     5. Durability Index means the percent loss of weight as determined using ASTM "Standard Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine", designated C131-89, or other approved ASTM procedure.

     6. Full Deployment means that sanding materials have been applied to all priority roadways targeted for treatment during a snow/ice event ((are sanded)).

     7. Percent Fines means the percent material passing a #100 sieve as determined by the American Society for Testing Materials (ASTM) "Standard Method for Sieve Analysis of Fine and Coarse Aggregates", Designation C136-84a (1988) (American Highway and Transportation Officials designation T27-88), or other approved ASTM procedure.

((This definition will remain in effect, even after the United States Environmental Protection Agency makes the determination that the PM10 standard that existed before September 16, 1997, no longer applies to Spokane County. Retaining the definition ensures compliance with the Environmental Protection Agency's Guidance for implementing the 1-Hour Ozone and Pre-Existing PM₁₀ NAAQS, dated December 29, 1997, by continuing implementation of control measures in the State Implementation Plan and preserving air quality gains.))

     ((9)) 10. Priority Roadway means any street, arterial, or highway, within the PM10 Nonattainment Area, with more than 15,000 average daily traffic count, and any connecting entrance or exit ramp.

If the affected entity incorporated after the effective date of this regulation, that entity shall submit an initial plan within 180 days of incorporation. In reviewing each plan, the Authority shall allow consideration of mobility and transportation safety factors. ((Approval of)) In approving any initial plan, ((shall require that)) or plan revision the Authority ((determine)) must make a finding, in consultation with the Washington State Department of Ecology, that the cumulative effect of the plans submitted by all affected entities will ((achieve and)) maintain at least a 70% reduction, from the 1992 - 1993 base season, in the 24 hour PM10 emissions from paved surfaces.

     3. Within 45 days of submittal of the reports required in Subsection ((G)) F. of this Section, the Authority shall determine if the plan commitments have been met and shall notify ((any)) each affected entity that has failed to ((meet plan commitments)) fully implement its plan.

     ((4. If the Authority determines that any governmental entity has failed to meet the plan commitments, the Authority, shall require that any affected governmental entity submit a revised plan within 30 days of notification by the Authority. The revised plan shall establish methods for meeting the plan commitments. Any revised plan must be implemented upon approval by the Authority.))

     ((5)) 4. If the Authority, after consultation with the affected ((governmental)) entities, the Washington Department of Ecology, and the United States Environmental Protection Agency, determines that the emission reduction and control plans do not provide for sufficient reduction in PM10 emissions to ((meet)) achieve the emission reduction credit for paved road surfaces as contained in the State Implementation Plan, the Authority may require ((the)) any or all affected ((governmental)) entities to modify their plans in order to achieve additional reductions.

     5. Each affected entity shall review their approved plan within 90 days of the effective date of the amendment to this regulation and every five (5) years thereafter and within 90 days of the Authority's determination made pursuant to subsection C.4. and revise the plan as appropriate to ensure that identified priority roadways reflect changes in traffic counts and driving patterns and that all aspects of the plan reflect current sanding and sweeping technologies, programs, and schedules of the affected entity and requirements of the Authority. All amended plans are subject to approval by the Authority.

     ((D. Sweeping requirements. Beginning the effective date of this regulation, the City of Spokane, Spokane County, and the Washington State Department of Transportation, or their contractors, shall clean all priority roadways in an expeditious manner following each sanding event when road conditions are appropriate and safety and mobility requirements have been satisfied.
