1. (2) Method of Sale of Gasoline-Alcohol Blends.

   1. (A) Method of Retail Sale. Notwithstanding any rule to the contrary, all motor fuel kept, offered or exposed for sale, or sold at retail containing at least one percent (1%) by volume of any alcohol shall be identified as such using the word contains or other wording approved by the director, in conjunction therein, the maximum volume percentages to the nearest whole percent and the name of each alcohol additive on the upper fifty percent (50%) of the dispenser front panel in a position clear and conspicuous from the driver’s position, in a type at least one-half inch (1/2") in height, one-sixteenth inch (1/16") stroke (width of type). Examples:

      CONTAINS 10% ETHANOL CONTAINS ALCOHOL 5% METHANOL 5% TERTIARY BUTANOL

   2. (B) Documentation for Dispenser Labeling Purposes. The retailer must be provided, at the time of delivery of the fuel on an invoice, bill of lading, shipping paper or other documentation, the presence and maximum amount of ethanol, methanol or any type of alcohol (in terms of percent by volume) contained in the fuel. This documentation is only for dispenser labeling purposes; it is the responsibility of any potential blender to determine the total oxygen content of the motor fuel before blending.

2. (3) Procedures for Storage of Motor Fuels Containing Alcohol Additives. The following procedures shall be used by retail outlets when the total alcohol content is over threetenths (0.3) volume percent:

   1. (A) Retail establishments offering any gasoline-alcohol blended fuel for the first time shall remove all water and precipitated materials from the storage tank before the gasoline-alcohol blend is delivered into the tank; and
   2. (B) A suitable filter, ten (10) microns or less, must be installed in the meter inlet or discharge line and immediately adjacent to the meter.

3. (4) Classification of Petroleum Fuels. When gasoline, illuminating oils, heating fuels or other motor fuels are sold or offered for sale in Missouri, the invoice bill of lading, shipping paper or other documentation must identify the name of the product, the particular grade of the product as designated by ASTM and when applicable the minimum octane (antiknock index) as listed in subsections (4)(A)–(G) of this section. All retail dispensing devices must conspicuously identify the name of the product, the particular grade of the product as designated and when applicable the minimum octane (antiknock index) as listed as follows:

   1. (A) Automotive gasoline shall be identified by leaded or unleaded and the octane (antiknock index) number. The octane posting shall be in accordance with the Federal Trade Commission (FTC) octane posting and certification rule;
   2. (B) Gasoline-alcohol blends shall be identified by leaded or unleaded and the octane number. The octane posting shall be in accordance with FTC octane posting and certification rule;
   3. (C) Aviation gasoline shall be identified by Grade 80, Grade 100 or Grade 100LL;
   4. (D) Aviation turbine fuels shall be identified by Jet A, Jet A-1 or Jet B;
   5. (E) Diesel fuel shall be identified by the grades No. 1-D, No. 2-D or No. 4-D;
   6. (F) Fuel oil shall be identified by the grades of No. 1, No. 2, No. 4 (Light), No. 4, No. 5 (Light), No. 5 (Heavy) or No. 6; and
   7. (G) Kerosene shall be identified by the grades of No. 1-K or No. 2-K. Grade No. 2- K sold or offered for sale at retail shall also post conspicuously on the front of the dispensing device, the words WARNING—NOT SUITABLE FOR USE IN UNVENTED HEATERS REQUIRING NO. 1-K in onehalf inch by one-sixteenth inch (1/2" × 1/16") strokes, block style letters.
4. (5) Retail Establishments—Retention of Delivery Tickets. The retailers shall retain on the premises to which kerosene or motor fuel has been delivered, copies of the loading ticket, manifest or delivery receipt for each grade of product received, subject to examination by the director upon request. If a delivery receipt is retained rather than a manifest or loading ticket, the delivery ticket shall bear the following information: vendor name, date of deliver, quantity of each grade, point of origin and the manifest or loading ticket number. The required retention of the loading ticket, manifest or delivery receipt shall be limited to the four (4) most recent receipts of each grade of product.
5. (6) Water in Retail Tanks. It shall be a violation for water to exceed one inch (1") in depth, when measured from the bottom through the fill pipe, of any tank utilized in the storage of regulated products sold at retail. Water must be removed from the tank prior to the delivery and subsequent selling of additional product from the storage tank.

6. (7) Stop Sale.

   1. (A) Retail Service Stations. A Stop Sale notice will be issued to retail service station dealers for kerosene or motor fuel failing to meet established specifications. A release from a Stop Sale order will be awarded only after final disposition has been agreed upon by the director. Confirmation for disposition shall be submitted in writing and contain an explanation for its failure to meet specifications. The Stop Sale will apply only to the location where sample analysis indicates specification violation. Upon discovery of fuels failing to meet established specifications, meter readings and physical inventory shall be taken and reported in the confirmation for disposition.
   2. (B) Bulk Storage Plants Including Terminals. A Stop Sale notice will be issued when petroleum products maintained in bulk plant facilities fail to meet specifications established by the director. The bulk storage plant immediately shall notify all customers that have received those products and make any arrangements necessary to replace or adjust to specifications those products. Confirmation of disposition of Stop Sale on products shall be made available in writing to the director. Specific variations or exemptions may be made for fuels used for blending purposes or designed for special equipment or services and for which it can be demonstrated that the distribution will be restricted to those uses.
