ODORIZATION

(1)Any gas distributed to customers through gas mains or gas services or used for domestic purposes in compressor plants, which does not naturally possess a distinctive odor to the extent that its presence in the atmosphere is readily detectable at all gas concentrations of one-fifth of the lower explosive limit and above, shall have an odorant added to it to make it so detectable. Odorization is not necessary when it is adequately odorized by the supplier. Suitable tests must be made to determine whether the odor meets the aforementioned standards.#
