§ 309.10   Alternative vehicle fuel rating.
(a) If you are an importer, producer, or refiner of non-liquid alternative vehicle fuel (other than electricity), you must determine the fuel rating of all non-liquid alternative vehicle fuel (other than electricity) before you transfer it. You can do that yourself or through a testing lab. To determine fuel ratings, you must possess a reasonable basis, consisting of competent and reliable evidence, for the minimum percentage of the principal component of the non-liquid alternative vehicle fuel (other than electricity) that you must disclose, and for the minimum percentages of other components that you choose to disclose. For the purposes of this section, fuel ratings for the minimum percentage of the principal component of compressed natural gas are to be determined in accordance with test methods set forth in American Society for Testing and Materials (“ASTM”) D 1945-91, “Standard Test Method for Analysis of Natural Gas by Gas Chromatography.” For the purposes of this section, fuel ratings for the minimum percentage of the principal component of hydrogen gas are to be determined in accordance with test methods set forth in ASTM D 1946-90, “Standard Practice for Analysis of Reformed Gas by Gas Chromatography.” This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies of D 1945-91 and D 1946-90 may be obtained from the American Society for Testing and Materials, 1916 Race Street, Philadelphia, PA 19103, or may be inspected at the Federal Trade Commission, Public Reference Room, room 130, 600 Pennsylvania Avenue, NW, Washington, DC, or at the National Archives and Records Administration (NARA). For information on the availability of this material at NARA, call 202-741-6030, or go to: http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html.
(b) If you are a manufacturer of electric vehicle fuel dispensing systems, you must determine the fuel rating of the electric charge delivered by the electric vehicle fuel dispensing system before you transfer such systems. To determine the fuel rating of the electric vehicle fuel dispensing system, you must possess a reasonable basis, consisting of competent and reliable evidence, for the following output information you must disclose: kilowatt (“kW”) capacity, voltage, whether the voltage is alternating current (“ac”) or direct current (“dc”), amperage, and whether the system is conductive or inductive.
§ 309.11   Certification.
(a) For non-liquid alternative vehicle fuel (other than electricity), in each transfer you make to anyone who is not a consumer, you must certify the fuel rating of the non-liquid alternative vehicle fuel (other than electricity) consistent with your determination. You can do this in either of two ways:
(1) Include a delivery ticket or other paper with each transfer of non-liquid alternative vehicle fuel (other than electricity). It may be an invoice, bill of lading, bill of sale, terminal ticket, delivery ticket, or any other written proof of transfer. It must contain at least these four items:
(i) Your name;
(ii) The name of the person to whom the non-liquid alternative vehicle fuel (other than electricity) is transferred;
(iii) The date of the transfer; and
(iv) The fuel rating.
(2) Give the person a letter or written statement. This letter must include the date, your name, the other person's name, and the fuel rating of any non-liquid alternative vehicle fuel (other than electricity) you will transfer to that person from the date of the letter onwards. This letter of certification will be good until you transfer non-liquid alternative vehicle fuel (other than electricity) with a lower percentage of the principal component, or of any other component disclosed in the certification. When this happens, you must certify the fuel rating of the new non-liquid alternative vehicle fuel (other than electricity) either with a delivery ticket or by sending a new letter of certification.
(b) For electric vehicle fuel dispensing systems, in each transfer you make to anyone who is not a consumer, you must certify the fuel rating of the electric vehicle fuel dispensing system consistent with your determination. You can do this in either of two ways:
(1) Include a delivery ticket or other paper with each transfer of an electric vehicle fuel dispensing system. It may be an invoice, bill of lading, bill of sale, delivery ticket, or any other written proof of transfer. It must contain at least these five items:
(i) Your name;
(ii) The name of the person to whom the electric vehicle fuel dispensing system is transferred;
(iii) The date of the transfer;
(iv) The model number, serial number, or other identifier of the electric vehicle fuel dispensing system; and
(v) The fuel rating.
(2) Make the required certification by placing clearly and conspicuously on the electric vehicle fuel dispensing system a permanent legible marking or permanently attached label that discloses the manufacturer's name, the model number, serial number, or other identifier of the system, and the fuel rating. Such marking or label must be located where it can be seen after installation of the system. The marking or label will be deemed “legible,” in terms of placement, if it is located in close proximity to the manufacturer's identification marking. This marking or label must be in addition to, and not a substitute for, the label required to be posted on the electric vehicle fuel dispensing system by the retailer.
(c) When you transfer non-liquid alternative vehicle fuel (other than electricity), or an electric vehicle fuel dispensing system, to a common carrier, you must certify the fuel rating of the non-liquid alternative vehicle fuel (other than electricity) or electric vehicle fuel dispensing system to the common carrier, either by letter or on the delivery ticket or other paper, or by a permanent marking or label attached to the electric vehicle fuel dispensing system by the manufacturer.
§ 309.12   Recordkeeping.
You must keep for one year records of how you determined fuel ratings. The records must be available for inspection by Federal Trade Commission staff members, or by people authorized by FTC.
§ 309.13   Certification.
(a) If you are a distributor of non-liquid alternative vehicle fuel (other than electricity), you must certify the fuel rating of the fuel in each transfer you make to anyone who is not a consumer. You may certify either by using a delivery ticket or other paper with each transfer of fuel, as outlined in § 309.11(a)(1), or by using a letter of certification, as outlined in § 309.11(a)(2).
(b) If you are a distributor of electric vehicle fuel dispensing systems, you must certify the fuel rating of the system in each transfer you make to anyone who is not a consumer. You may certify by using a delivery ticket or other paper with each transfer, as outlined in § 309.11(b)(1), or by using the permanent marking or permanent label attached to the system by the manufacturer, as outlined in § 309.11(b)(2).
(c) If you do not blend non-liquid alternative vehicle fuels (other than electricity), you must certify consistent with the fuel rating certified to you. If you blend non-liquid alternative vehicle fuel (other than electricity), you must possess a reasonable basis, consisting of competent and reliable evidence, as required by § 309.10(a), for the fuel rating that you certify for the blend.
(d) When you transfer non-liquid alternative vehicle fuel (other than electricity), or an electric vehicle fuel dispensing system, to a common carrier, you must certify the fuel rating of the non-liquid alternative vehicle fuel (other than electricity) or electric vehicle fuel dispensing system to the common carrier, either by letter or on the delivery ticket or other paper, or by a permanent marking or label attached to the electric vehicle fuel dispensing system by the manufacturer. When you receive non-liquid alternative vehicle fuel (other than electricity), or an electric vehicle fuel dispensing system, from a common carrier, you also must receive from the common carrier a certification of the fuel rating of the non-liquid alternative vehicle fuel (other than electricity) or electric vehicle fuel dispensing system, either by letter or on the delivery ticket or other paper, or by a permanent marking or label attached to the electric vehicle fuel dispensing system by the manufacturer.
§ 309.14   Recordkeeping.
You must keep for one year any delivery tickets, letters of certification, or other paper on which you based your fuel rating certifications for non-liquid alternative vehicle fuels (other than electricity) and for electric vehicle fuel dispensing systems. You also must keep for one year records of any fuel rating determinations you made according to § 309.10. If you rely for your certification on a permanent marking or permanent label attached to the electric vehicle fuel dispensing system by the manufacturer, you must not remove or deface the permanent marking or label. The records must be available for inspection by Federal Trade Commission staff members, or by persons authorized by FTC.
§ 309.15   Posting of non-liquid alternative vehicle fuel rating.
(a) If you are a retailer who offers for sale or sells non-liquid alternative vehicle fuel (other than electricity) to consumers, you must post the fuel rating of each non-liquid alternative vehicle fuel. If you are a retailer who offers for sale or sells electricity to consumers through an electric vehicle fuel dispensing system, you must post the fuel rating of the electric vehicle fuel dispensing system you use. You must do this by putting at least one label on the face of each fuel dispenser through which you sell non-liquid alternative vehicle fuel. If you are selling two or more kinds of non-liquid alternative vehicle fuels with different fuel ratings from a single fuel dispenser, you must put separate labels for each kind of non-liquid alternative vehicle fuel on the face of the fuel dispenser.
(b)(1) The label, or labels, must be placed conspicuously on the fuel dispenser so as to be in full view of consumers and as near as reasonably practical to the price per unit of the non-liquid alternative vehicle fuel.
(2) You may petition for an exemption from the placement requirements by writing the Secretary of the Federal Trade Commission, Washington, DC 20580. You must state the reasons that you want the exemption. Petitions for exemptions will be handled pursuant to the procedures prescribed in § 1.31 of this chapter.
(c) If you do not blend non-liquid alternative vehicle fuels (other than electricity), you must post consistent with the fuel rating certified to you. If you blend non-liquid alternative vehicle fuel (other than electricity), you must possess a reasonable basis, consisting of competent and reliable evidence, as required by § 309.10(a), for the fuel rating that you post for the blend.
(d)(1) You must maintain and replace labels as needed to make sure consumers can easily see and read them.
(2) If the labels you have are destroyed or are unusable or unreadable for some unexpected reason, you may satisfy this part by posting a temporary label as much like the required label as possible. You must still get and post the required label without delay.
(e) The following examples of fuel rating disclosures for CNG and hydrogen are meant to serve as illustrations of compliance with this part, but do not limit the rule's coverage to only the mentioned non-liquid alternative vehicle fuels (other than electricity):
(1) “CNG”
(2) “Hydrogen”
(f) The following example of fuel rating disclosures for electric vehicle fuel dispensing systems is meant to serve as an illustration of compliance with this part:
(g) When you receive non-liquid alternative vehicle fuel (other than electricity), or an electric vehicle fuel dispensing system, from a common carrier, you also must receive from the common carrier a certification of the fuel rating of the non-liquid alternative vehicle fuel (other than electricity) or electric vehicle fuel dispensing system, either by letter or on the delivery ticket or other paper, or by a permanent marking or label attached to the electric vehicle fuel dispensing system by the manufacturer.
§ 309.16   Recordkeeping.
You must keep for one year any delivery tickets, letters of certification, or other paper on which you based your posting of fuel ratings for non-liquid alternative vehicle fuels. You also must keep for one year records of any fuel rating determinations you made according to § 309.10. If you rely for your posting on a permanent marking or permanent label attached to the electric vehicle fuel dispensing system by the manufacturer, you must not remove or deface the permanent marking or label. The required records, other than the permanent marking or label on the electric vehicle fuel dispensing system, may be kept at the retail outlet or at a reasonably close location.
