II.A.Applicability

II.A.1. The provisions of this Section II shall apply to any governmental entity and any employee, official, representative, or agent of such governmental entity responsible for applying street sanding material to any roadway in the Denver PM10 Attainment/Maintenance area as defined in the AQCC Ambient Air Standards Regulation (effective date: July 30, 1991).

II.B.2. "Street Sanding Material(s)," when used in Section II, Street Sanding Requirements Specific to the Denver PM10 Attainment/Maintenance Area, means natural geologic material, including sand and sodium chloride rock salt but excluding other de-icing chemicals, used to provide increased traction or de-icing on roadways.

II.B.4. "Uncontrolled levels of wintertime street sand and road dust emissions" shall be calculated using historical 1989 data.

II.C.Requirements

II.C.1. Each user shall establish and document its base sanding amount. Documentation of the base sanding amount shall be submitted to the Division and the Regional Air Quality Council (RAQC) by September 30, 1993.

II.C.2. Except as otherwise provided in sections II.C.4, II.C.5 and II.C.6; each user shall achieve a 30% reduction of uncontrolled levels of wintertime street sand and paved road dust emissions on roadways within their jurisdiction in the PM10 attainment/maintenance area, excepting those roadways within the foothills area.

II.C.3. Each user shall achieve a 20% reduction from uncontrolled levels of wintertime street sand and paved road dust emissions on those roadways within the foothills area of their jurisdiction.

II.C.4. The City and County of Denver shall achieve a 72% reduction from uncontrolled levels of wintertime street sand and paved road dust emissions on roadways in the central business district (CBD). The CBD is defined as the area bounded by and inclusive of Colfax Avenue, Speer Boulevard, Wynkoop Street, 20th Street, and Broadway.

II.C.5. The Colorado Department of Transportation (CDOT) shall achieve a 54% reduction from uncontrolled levels of wintertime street sand and paved road dust emissions from Interstate 25 and its entrance/exit ramps between 6th Avenue and University Boulevard.

II.C.6 The City and County of Denver and CDOT shall achieve a 50% reduction from uncontrolled levels of wintertime street sand and paved road dust emissions on roadways within the area bounded by, and including, Federal Boulevard, Downing Street, 38th Avenue, and Louisiana, except as otherwise provided by sections II.C.4 and II.C.5.

II.D.Recordkeeping and Reporting

II.D.1. No later than June 30, 2001 and each year thereafter, users of street sanding material covered by this section shall submit a report to the Division and the RAQC containing the following information for the preceding twelve months or the preceding calendar year:

II.D.1.a. the total number of miles driven by maintenance trucks during snow and ice removal operations;

II.D.1.b. the total amount of sanding material (both new and recycled), salt, and other deicing chemicals used;

II.D.1.c. the number and dates of full deployment episodes;

II.D.1.d. the number of lane miles typically sand ;d during c :h full deployment;

II.D.1.e. the percent of the sanded roadways swept within 4 days of a sanding event; and

II.E.Compliance Methodology

II.E.1. The calculation of the percent reduction from uncontrolled levels of wintertime street sand and paved road dust emissions shall be based on the reduction in street sand from the base sanding amount, the percent of roadways swept within four days of a sanding event, and the latest data on the emission benefits of street sanding materials, de-icing agents, and street sweeping equipment, which is consistent with the methodology used for the 2001 PM10 maintenance plan.
