Tha piping is constructed of metal without <br />additional corrosion protection measures* provided that: <br />(1) the piping is installed at a site that is <br />determlned’by a corrosion expert to not be corrosive enough to <br />causa it to have a release due to corrosion during its operating <br />life; and <br />(2) owners and operators maintain records that <br />demonstrate compliance with subitem (1) for the remaini''.g life <br />of the piping. <br />D. The piping construction and corrosion protection <br />are determined by the commissioner to be designed to prevent the <br />release or threatened release of a stored regulated substance in <br />a manner that is no less protective of human health and the <br />environment than the requirements of items A to C. The <br />commissioner's determination under this item must be obtained in <br />writing and the tank owners and operators must keep the <br />determination for the life of the tank. <br />Subp. 5. Codes of practice for piping. Codes of practice <br />for subpart 4 are described in items A to C. <br />A. The following codes of practice apply to subpart <br />4* item A; <br />(1) Onderwriters Laboratories OL 567* Pipe <br />Connectors for riaamable and Combustible Liquids and LPHSas; <br />(2) Onderwriters Laboratories of Canada <br />CAM4*S633*‘H84* Plexible Onderground Hose Connectors for <br />flammable and Combustible Liquids; or <br />(3) Onderwriters Laboratories of Canada OLC <br />Subject C107C*M1984* Guide for Class Fibre Reinforced Plastic <br />Pipe and fittings for Flammable Liquids. <br />B.
