Current through Register Vol. 50, No. 6, June 20, 2024
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.
