Section 20.5.106.610 - PERFORMANCE STANDARDS FOR STEEL PIPING FOR UST SYSTEMS

A. If owners and operators construct or operate piping of steel for a UST system, owners and operators shall:

(1) coat the piping with a suitable dielectric material;

(2) field-install a cathodic protection system designed by a corrosion expert; and

(3) design any impressed current system to allow ready determination of current operating status as required in Subsection C of 20.5.107.705 NMAC.

B. Owners and operators shall ensure that the piping meets the requirements of the current edition of an industry standard or code of practice developed by a nationally recognized association or independent testing laboratory approved in advance by the department, and that the piping is approved by the manufacturer for the application for which it is to be used. Owners and operators shall use one or more of the following to comply with the requirements of this section:

(1)American Petroleum Institute Recommended Practice 1632, "Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems";

(2)Underwriters Laboratories Subject 971A, "Outline of Investigation for Metallic Underground Fuel Pipe";

(3)Steel Tank Institute Recommended Practice R892, "Recommended Practice for Corrosion Protection of Underground Piping Networks Associated with Liquid Storage and Dispensing Systems";

(4)NACE International Standard Practice SP0169, "Control of External Corrosion on Underground or Submerged Metallic Piping Systems"; or

(5)NACE International Standard Practice SP0285, "External Corrosion Control of Underground Storage Tank Systems by Cathodic Protection".

C. If owners and operators construct piping of steel for a UST system without additional corrosion protection measures, owners and operators shall only install the piping at a site that is approved, in writing, in advance of installation, by a corrosion expert, to not be corrosive enough to cause the piping to have a release due to corrosion during its operational life. Owners and operators shall maintain records that demonstrate compliance with this requirement for the remaining life of the piping.

D. If owners and operators install or operate steel piping above ground that connects to an emergency generator or loading rack, they shall:

(1) meet the requirements in Subsection D of 20.5.106.608 NMAC;

(2) meet the requirements in Subsection A of 20.5.106.610 NMAC; and

(3) meet the requirements in 20.5.109.915 NMAC for the above ground steel portion of the piping.
