§ 25-7-139. Methyl tertiary butyl ether - prohibition - phase-out - civil penalty.
(1) The general assembly finds and declares that methyl tertiary butyl ether ("MTBE") is an oxygenate used in gasoline and other fuel products in this state and in the United States. The general assembly also finds that MTBE may leak into and contaminate groundwater supplies, and that MTBE is water soluble and therefore is difficult and costly to remove from water. MTBE is colorless, tastes and smells like turpentine, and can be tasted and detected by smell at extremely low concentrations. MTBE may be a human carcinogen and poses other potential health risks, including but not limited to memory loss, asthma, and skin irritation.
(2) The general assembly further finds and declares that water is precious and vital to this state's growing population, agricultural industry, and unique environment. Therefore it is the intent of the general assembly in enacting this section to halt further contamination and pollution of this state's groundwater supplies by MTBE.
(3) (a) (I) Except as otherwise provided in this paragraph (a), a person may not sell, offer for sale, or store any fuel product containing or treated with MTBE.
(II) The provisions of this paragraph (a) shall not apply if the presence of MTBE in a fuel product is caused solely by incidental commingling of MTBE with the fuel product during storage or transfer of the fuel product. In no event shall the provisions of this subsection (3) be construed to permit the knowing or willful addition of MTBE to any fuel product.
(b) (Deleted by amendment, L. 2005, p. 283, § 21, effective August 8, 2005.)
(c) For purposes of this section, "fuel product" means gasoline, reformulated gasoline, benzine, benzene, naphtha, benzol, and kerosene and any other volatile and inflammable liquid that is produced, compounded, and offered for sale or used for the purpose of generating power in internal combustion engines or generating heat or light or used for cleaning or for any other similar usage.
(4) Any person who violates the provisions of this section shall be subject to a civil penalty as provided in section 25-7-122 (1)(e).
