(2) upgrade requirements in Subsection B of 20.5.106.607 NMAC; or

(3) closure requirements in 20.5.115 NMAC.

B. UST upgrading requirements. Owners and operators must have upgraded existing steel USTs by the effective date of these regulations to meet one of the following requirements in accordance with 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. Steel USTs that have not been upgraded by the effective date of these regulations shall be immediately permanently closed in accordance with 20.5.115 NMAC.

(1) Internal lining.
(a) USTs upgraded by internal lining must meet the following:
(i) the lining was installed in accordance with an industry standard or code of practice developed by a nationally recognized association or independent testing laboratory that was approved in advance by the department, and

(ii) within 10 years after installation of internal lining and every five years thereafter, the lined UST is required to be internally inspected in accordance with the current edition of an industry standard or code of practice developed by a nationally recognized association or independent testing laboratory, or manufacturer's recommendation, approved in advance by the department.

(b) One of the following shall be used to comply with internal lining upgrading requirements:
(i) National Leak Prevention Association Standard 631, Chapter B, "Future Internal Inspection Requirements for Lined Tanks";

(2) Cathodic protection. USTs upgraded by cathodic protection shall meet the requirements of 20.5.106.602 NMAC and owners and operators must have ensured the integrity of the tank by:
(a) performing internal inspections and assessments to ensure that the tank was structurally sound and free of corrosion holes prior to installing the cathodic protection system; or

(b) if the tank had been installed for less than 10 years, by either having monitored monthly for releases in accordance with 20.5.108 NMAC or by having assessed for corrosion holes by conducting two tightness tests that met the requirements of 20.5.108 NMAC and that were approved in advance by the department. Owners and operators must have conducted the first tightness test prior to installing the cathodic protection system. Owners and operators must have conducted the second tightness test between three and six months following the first operation of the cathodic protection system.
