Section 74:56:01:10 - Upgrading of existing USTs - Specific requirements

All existing USTs must meet each of the following upgrade requirements:

(1) Spill and overfill protection. To prevent spilling and overfilling associated with product transfer to the UST system, all existing UST systems must comply with the spill and overfill prevention equipment requirements for new USTs specified in § 74:56:01:07;

(2) Release detection. UST system owners or operators shall provide a method or combination of methods of release detection that can detect a release from any portion of the tank and the connected underground piping that routinely contains product. The release detection method must be installed, calibrated, operated, and maintained in accordance with the manufacturer's instructions and must meet the performance requirements of § 74:56:01:24 or the owners or operators shall permanently close the UST system or systems;

(3) Piping upgrade. Metal piping that routinely contains regulated substances and is in contact with the ground must be cathodically protected in accordance with a code of practice developed by a nationally recognized association or independent testing laboratory as specified in 40 C.F.R. § 280.20 as published at 80 FR 41566 (July 15, 2015), and must meet the cathodic protection requirements for tanks detailed in subdivision (4) of this section;

(4) Cathodic protection and interior lining. Existing steel USTs must be upgraded to meet one of the following requirements in accordance with a code of practice developed by a nationally recognized association or independent testing laboratory as specified in 40 C.F.R. § 280.21 as published at 80 FR (July 15, 2015):

(a) Cathodic protection. UST systems may be upgraded by cathodic protection if the system selected meets the requirements of § 74:56:01:14 and the integrity of the tank is ensured by one of the following methods:

(i) Inspecting the tank to ensure it is sound and free of corrosion holes prior to installation of the cathodic protection system;

(ii) Ensuring that the tank has been installed for less than ten years and monitoring the tank for releases in accordance with § 74:56:01:24;

(iii) Ensuring that the tank has been installed for less than ten years and assessing the tank for corrosion holes by conducting two tightness tests, the first test before the cathodic protection system is installed and the second test between three and six months after the first operation of the cathodic protection system; or

(iv) Assessing the tank for corrosion holes by a method approved by the department; or

(b) Interior lining. Existing USTs may be upgraded by internal lining if the internal lining, used alone, is installed in accordance with the requirements of § 74:56:01:19 or the internal lining, in combination with cathodic protection, is installed in accordance with the requirements of § 74:56:01:19 and the cathodic protection system meets the requirements of § 74:56:01:14.
