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 latest 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.

The test method must be a modified D130 method consisting of a glass test tube sealed inside a stainless steel pressure vessel run for 3 hrs at 122°F (50°C) and using the standard silver strip and rating scale found in IP 227.
Oxygenated fuel is a fuel containing substantial amounts of oxygenated components typically alcohols (such as ethanol) or ethers (such as methyl tert-butyl ether). A substantial amount of oxygenate is defined as a fuel containing more than 0.35 mass % oxygen (0.15 Methanol only).
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.

* EPA requires low sulfur, limited aromatic content, 40 cetane index diesel fuels be used by on-highway vehicles and high sulfur diesel fuels to be dyed red with Solvent Red 164 in amounts to make its presence visually apparent. The IRS specifies the amount of red dye (Solvent Red 164) required to be spectrally equivalent to 3.9 lbs per thousand barrels solvent red dye 26 at or beyond terminals. This is also applicable to low sulfur fuels sold tax exempt from terminals.
