§115.510.  Cutback Asphalt Definitions.

(Approved by EPA 12/22/1999 (64 FR 71666) effective 2/22/2000.)

      The following terms, when used in this division (relating to Cutback Asphalt), shall have the following meanings, unless the context clearly indicates otherwise.  Additional definitions for terms used in this division are found in §115.10 of this title (relating to Definitions), §101.1 of this title (relating to Definitions), and §3.2 of this title (relating to Definitions).

            (1)  Asphalt emulsion - An emulsion consisting of a continuous and discontinuous phase, composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent.

            (2)  Conventional cutback asphalt - Any cutback asphalt which does not meet the definition of an exempt cutback asphalt.

            (3)  Cutback asphalt - Any asphaltic cement which has been liquified by blending with petroleum solvents (diluents).

            (4)  Exempt cutback asphalt - Any cutback asphalt which, when tested in accordance with American Society of Testing Materials Test Method D 402, “Distillation of Cutback Asphalt Products,” as published in the 1997 edition of the Annual Book of ASTM Standards, shows the distillate fraction recovered up to 260 degrees Celsius (500 degrees Fahrenheit) to be less than 5.0% by volume of the total distillate recovered up to a temperature of 316 degrees Celsius (680 degrees Fahrenheit).

Adopted by TNRCC July 28, 1999, effective August 18, 1999

§115.512.  Control Requirements.

(As approved by EPA 12/22/1999 (64 FR 71666) effective 2/22/2000.)

The following control requirements shall apply in Nueces County and the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas as defined in §115.10 of this title (relating to Definitions).

            (1)  The use of conventional cutback asphalt containing volatile organic compounds (VOC) solvents for the paving of roadways, driveways, or parking lots is restricted to no more than 7.0% of the total annual volume averaged over a two-year period of asphalt used or specified for use by any state, municipal, or county agency who uses or specifies the type of asphalt application.

            (2)  In the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas, no person shall allow the use, application, sale, or offering for sale of conventional cutback asphalt containing VOC solvents for paving roadways, driveways, or parking lots during the period from April 16 to September 15 of any year.

            (3)  When asphalt emulsion is used or produced, the maximum VOC content shall not exceed 12% by weight or the following limitations, whichever is more stringent:

77A               (A)  0.5% by weight for seal coats;

77A               (B)  3.0% by weight for chip seals when dusty or dirty aggregate is used;

77A               (C)  8.0% by weight for mixing with open graded aggregate with less than 1% by weight of dust or clay-like materials adhering to the coarse aggregate fraction (1/4 inch in diameter or greater); and

77A               (D)  12.0% by weight for mixing with dense graded aggregate when used to produce a mix designed to have 10% or less voids when fully compacted.

As adopted by TNRCC July 28, 1999 effective August 18, 1999

§115.513.  Alternate Control Requirements.

(Approved by EPA 12/22/1999 (64 FR 71666) effective 2/22/2000.)

      Alternate methods of demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria in this division may be approved by the executive director in accordance with §115.910 of this title (relating to Availability of Alternate Means of Control) if emission reductions are demonstrated to be substantially equivalent.

§115.515.  Testing Requirements.

(Approved by EPA 12/22/1999 (64 FR 71666) effective 2/22/2000.)

      Compliance with §115.510 and §115.512 of this title (relating to Cutback Asphalt Definitions; and Control Requirements) shall be determined by applying the following test methods, as appropriate:

            (1)  American Society of Testing and Materials (ASTM) Test Method D 244, “Standard Test Methods for Emulsified Asphalts, Sections 11 to 15, Residue and Oil Distillate by Distillation,” as published in the 1997 edition of the Annual Book of ASTM Standards, for determining volatile organic compound (VOC) content of asphalt emulsions;

            (2)  ASTM Test Method D 402, “Standard Test Method for Distillation of Cut-Back Asphaltic Products,” as published in the 1997 edition of the Annual Book of ASTM Standards, for determining the VOC content of cutback asphalt; or

            (3) minor modifications to these test methods approved by the executive director.

Adopted by TNRCC July 28, 1999, effective August 18, 1999
