Section IX-129 - Odorizing Gases

A. Odorization and verification of odorization in liquefied petroleum gases shall be in accordance with the following provisions.

1. Except as otherwise provided in this Subchapter, each refinery, commercial storage facility, natural gas processing plant, pipeline, or other person which sell liquefied petroleum gas to a transporter, dealer, or distributor for distribution into the distribution chain to consumers shall odorize the liquefied petroleum gas in accordance with the provisions of this Subchapter.

2. Liquefied petroleum gas shall not be required to be odorized if it is to be delivered to a manufacturer of products of which liquefied petroleum gas forms a component part, to any facility for further processing, to a commercial storage facility, a natural gas processing plant, a refinery, a pipeline, or when odorization would be harmful in further use or processing of the gas and would not serve a useful purpose as a warning agent in further use or processing of the gas.

3. Liquefied petroleum gas, which is required to be odorized, shall be effectively odorized by an approved agent of such character as to positively, by a distinctive odor, the presence of gas down to concentrations in air of not over one-fifth the lower limit of flammability. The presence of odorization, when required, shall be positively verified by the dealer by a sniff test or other means, and the results shall be documented prior to delivery into his bulk plant, or when a shipment bypasses a bulk plant, prior to delivery to a consumer. It is the intent of this Paragraph to prohibit the sale or delivery of liquefied petroleum gas by a dealer to a consumer without the required odorization.

4. The odorization requirement shall be considered to be met by the use of 1 pound of ethyl mercaptan, 1 pound of thiophane, or 1.4 pounds of amyl mercaptan per10,000 gallons of liquefied petroleum gas, subject to the provisions of Paragraph 5 of this Subsection.

5. In order to maintain the minimum concentrations of odorant in the liquefied petroleum gas at the point of use by the consumer, the rules and regulations recommend that each person who is required to odorize gas under this Section use 1 1/2 pounds of odorant per 10,000 gallons of liquefied petroleum gas at the point of odorization.

6. The only approved odorants are those specified in Paragraph 4 of this Subsection; however, the commission may authorize, by rule, the use of other odorants which are equal in effectiveness to the odorants specified in Paragraph 4 of this Subsection.

7. The commission shall require each person who transports liquefied petroleum gas that is exempt from the odorization requirements of this Section to keep records of all purchases of unodorized gas for 3 years. The records shall include bills of lading, loading tickets and records of all deliveries of unodorized gas. Each delivery ticket and bill of lading shall be identified by reference to the bill of lading number.
