1.0 GENERAL

1.1 APPLICABILITY
1.1.1 A person shall not discharge to the atmosphere volatile organic compounds (VOC's) caused by the use or manufacture of Cutback or Emulsified asphalts for paving, road construction or road maintenance, unless such manufacture or use complies with the provisions of this Rule.

1.2 EXEMPTIONS

1.2.1 The provisions of Section 3.0 shall not apply to:
1.2.2 The use of cutback asphalt or emulsified asphalt in the manufacturing of paving materials where such materials are for immediate shipment and eventual use outside of the County of Placer, State of California, and where such area is designated as attainment for the State and Federal Ozone Standard.
1.2.3 The use of medium cure cutback asphalt during the months of the year when the National Weather Service forecasts that atmospheric temperature for the 24-hour period following application will not exceed 10^o C (50^o F).

2.0 DEFINITIONS

2.1 ASPHALT - is defined as a dark brown to black cementitious material (solid, semisolid, or liquid in consistency) of which the main constituents are bitumens which occur naturally or as a residue of petroleum refining.
2.2 CUTBACK ASPHALT - is defined as paving grade asphalts liquified with petroleum distillate and conforming to specifications of the American Society for Testing & Materials (ASTM) as follows:
Rapid Cure Type: ASTM D2028
Medium Cure Type: ASTM D2027
Slow Cure Type: ASTM D2026
2.3 EMULSIFIED ASPHALT - is defined as any asphalt liquified with water containing an emulsifier.
2.4 PAVING MATERIAL - is defined as a mixture consisting mainly of an asphalt and aggregate.
2.5 PAVING AND MAINTENANCE OPERATIONS - is defined as all activities involved in the new construction and maintenance of roadways and parking areas.
