Rule 40-20-1-.01. Standards for Petroleum Products
Pursuant to the provisions and requirements of O.C.G.A. Section 10-1-155, the following rules and regulations are hereby promulgated and the standards and specifications for petroleum products used for heating, cooking, illuminating, and power purposes are hereby defined. The following specifications, unless noted, will be determined in accordance with the test methods presented in the latest edition of the American Society for Testing and Materials Standards (ASTM). The State Oil Laboratory may utilize test methods other than those referenced when deemed technically or analytically suitable. The Department of Agriculture may write and publish guidelines related to performance standards and specifications of specialty fuels and other petroleum products that are not otherwise addressed by regulation. The latest version of the Annual Book of ASTM Standards Section Five and the late version of the NIST Handbook 130 were used in part for this rule. There may be additional preemptive state or federal requirements other than those identified.

(b) Spark Ignition Engine Fuel Oxygenated will be as follows:
1. Oxygenated motor fuels must meet all applicable requirements for automotive gasoline established in the preceding sections. However, an oxygenate blend consisting of 90% gasoline and 10% denatured ethanol or 85% gasoline and 15% denatured ethanol, where the ethanol (only) content is 9-15% by volume (3.1 - 5.8) mass % oxygen as ethanol, may have the following volatility requirements for the T50 minimum distillation temperature, vapor/liquid ratio and vapor pressure:
3. CBOB/RBOB are a hydrocarbon mixture similar to gasoline that may not meet specifications until blended with a specific amount of in- tended oxygenate. For this reason CBOB/RBOB must not be shipped from a terminal prior to blending and becoming finished product. Shipments between terminals and shipments between terminals and Sanctioned Oxygenate Blending Facilities are excluded from this prohibition. Sanctioned Oxygenate Blenders are considered to be manufacturers of oxygenated gasoline and are responsible for insuring that such products are in compliance with specifications established by the state oil chemist and approved by the Commissioner of Agriculture.
Prospective Oxygenate Blenders must file with the Commissioner of Agriculture a declaration or statement that they desire to sell such products in the state. The declaration or statement must furnish the name, brand, or a trademark of the product which they desire to sell, together with the name and address of the Oxygenate Blender. Owners and operators of Prospective Oxygenate Facilities must also file with the Commissioner of Agriculture a declaration or statement identifying by name and address of each Oxygenate Blending Facility owned or operated by such person.
