1. (1) LP Gas facilities that are located in a public place shall be inspected by a certified LP Gas technician every five years for leaks in any buried piping as follows:

   1. (a) if a leak is detected and repaired, the buried piping shall again be pressure tested for leaks;
   2. (b) the certified LP Gas technician shall keep a written record of the inspection and any corrections made to the buried piping located in a public place; and
   3. (c) the inspection records shall be available to be inspected on a regular basis by the division.

(2) When the division is required to complete more than two inspections to receive compliance on an LP Gas System, container, apparatus, appliance, appurtenance, tank or tank trailer, or any pertinent equipment for the storage, transportation, or dispensation of LP Gas, the division shall charge to the owner for each additional inspection or re-inspection fee.

3. (3) LP Gas containers of more than 5,000 water gallons shall be inspected at least biannually for compliance with Title 53, Chapter 7, Part 3, Liquefied Petroleum Gas Act and this rule. The following containers are exempt from this requirement:

   1. (a) those excluded from the act in Section 53-7-303;
   2. (b) containers under federal control;
   3. (c) containers under the control of the U.S. Department of Transportation and used for transportation of LP Gas; and
   4. (d) containers located at private residences.

5. (5) American Society of Testing and Materials (ASTM) A-212 Steel pressure propane containers greater than 5,000 water gallons may not be brought into the state or relocated within the state. Effected Containers are identified with material as SA212, SA212A, SA212B, A212B or other identified as 212 material construction.

6. (6) The following are amendments and additions to the codes and standards adopted under Section 15A-5-103 to regulate LPG systems:

   1. (a) NFPA, Standard 58, Section 5.2.1.1 is amended to add the following section: (d) All new, used or existing containers of 5,000 water gallons or less, installed in the state or relocated within the state shall be marked with the ASME stamp as defined in Subsection R710-6-3(3). All new, used or existing containers of more than 5,000 water gallons, installed in the state or relocated within the state, shall be marked with the ASME stamp as defined in Subsection R710-6-3(3), and shall be inspected for approval by the division. If the division has concerns about the integrity or condition of the container, additional nondestructive testing may be required to include hydrostatic testing, ultrasonic metal thickness testing or any other testing as determined necessary by the division. All incurred costs for additional testing required by the division shall be the responsibility of the owner.
   2. (b) NFPA, Standard 58, Section 5.2.1.1 is amended to add the following section: (e) If an existing U68, U69, U200 or U201 specification container, more than 5,000 water gallons, is relocated within the state, and does not bear the required ASME stamp as defined in Subsection R710-6-3(3), the container cannot be reinstalled unless the container has received a "Special Classification Permit" from the division. Specifications of the type of container, container history if known, material specifications and calculations, and condition of the container shall be submitted to the division by the person seeking the "Special Classification Permit". The division shall inspect the container for approval. If the division has concerns about the integrity or condition of the container, additional nondestructive tests such as hydrostatic testing, ultrasonic metal thickness testing or any other testing as determined necessary by the division. All incurred costs of testing and evaluations shall be the responsibility of the owner. The division will approve or disapprove the proposed container. Approval by the division shall be obtained before the container is set or filled with LP Gas.
   3. (c) NFPA, Standard 58, Section 5.2.1.6 is amended to add the following sentence at the end of the section: (A) Repairs and alterations shall only be made by those holding a National Board "R" Certificate of Authorization commonly known as an R Stamp.
   4. (d) NFPA Standard 58, Sections 5.11.3.2.1(2)(a) and (b) are deleted and rewritten as follows: Type K copper tubing without joints below grade may be used in exterior LP Gas piping systems only.
   5. (e) NFPA, Standard 58, Section 6.8.3 is amended to add the following section: 6.8.3.5 Skid mounted ASME horizontal containers greater than 2000 water gallons, with non-fireproofed steel mounted attached supports, resting on concrete, pavement, gravel or firm packed earth, may be mounted on the attached supports to a maximum of 12 inches from the top of the skid to the bottom of the container.

   6. (f) NFPA, Standard 58, Section 6.8.7 is amended to add the following: (N) All metallic equipment and components that are buried or mounded shall have cathodic protection installed to protect the metal and shall meet the following requirements:

      1. (i) sacrificial anodes shall be installed as required by the size of the container. If more than one sacrificial anode is required they shall be evenly distributed around the container;
      2. (ii) sacrificial anodes shall be connected to the container or piping as recommended by the manufacturer or using accepted engineering practices; and
      3. (iii) sacrificial anodes shall be placed as near the bottom of the container as possible and about two feet away from the container.
   7. (g) NFPA, Standard 58, Section 6.27.3.19 is added as follows: On dispensing installations, 1,000 gallon water capacity or less, where the dispensing cabinet is located next to the LP Gas container, stainless steel wire braid hose of more than 36 inches in length may be used on vapor and liquid return lines only. The hose shall be secured and routed in a safe and professional manner.
   8. (h) NFPA, Standard 58, Section 8.4.1.1(1) is amended as follows: On line one remove "5ft (1.5m)" and replace it with "10 ft (3m)".
