Section 20.5.110.1010 - REPAIRS, REPLACEMENTS AND MODIFICATIONS

Owners and operators of a storage tank system shall ensure that repairs, replacements, and modifications will prevent releases due to structural failure or corrosion as long as the storage tank system is used to store regulated substances. Owners and operators shall remove all regulated substances from a storage tank system when a release has been confirmed until it is repaired or replaced in accordance with the requirements of this section.

A. Determining whether repair, replacement or modification is necessary. Owners and operators shall determine whether a repair, replacement or modification to a storage tank system is necessary in consultation with a department inspector, after providing notice required by this part.

(1) If owners and operators are repairing, replacing or modifying piping of any kind that is connected to a storage tank, the determination shall be made during an on-site inspection that provides the inspector the opportunity to view the piping while it is exposed.

(2) If, during an on-site inspection, the inspector determines that:

(a) any steel piping connected to a tank indicates corrosion; or

(b) any non-corrodible piping connected to a tank shows signs of deterioration or failure,

(3) Then the owner and operator shall replace all piping connected to that tank, and shall inspect all other piping at the same facility that is made of the same material to determine its condition prior to returning the facility to operation.

B. Owners and operators shall properly conduct repairs, replacements and modifications to storage tank systems 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, and in accordance with the manufacturer's instructions and recommended practices. Owners and operators shall use one or more of the following to comply with the requirements of this section:

(1)National Fire Protection Association Standard 30, "Flammable and Combustible Liquids Code";

(2)American Petroleum Institute Recommended Practice RP 2200, "Repairing Crude Oil, Liquefied Petroleum Gas, and Product Pipelines";

(3)National Fire Protection Association Standard 30A, "Code for Motor Fuel Dispensing Facilities and Repair Garages";

(4)Petroleum Equipment Institute Publication RP200, "Recommended Practices for Installation of Above Ground Storage Systems for Motor Vehicle Fueling";

(5)American Society for Testing and Materials ES40, "Emergency Standard Practice for Alternative Procedures for the Assessment of Buried Steel Tanks Prior to the Addition of Cathodic Protection";

(6)American Petroleum Institute 570, "Piping Inspection Code: Inspection, Repair, Alteration and Rerating of In-Service Piping Systems";

(7)American Petroleum Institute Standard 653, "Tank Inspection, Repair, Alteration, and Reconstruction";

(8)American Society of Mechanical Engineering Standard B31.1, "Process Piping";

(9)International Code Council, "International Fire Code";

(10)National Leak Prevention Association Publication RP823, "Standard for Preventative Maintenance, Repair, and In-situ Construction of Petroleum Sumps";

(11)Petroleum Equipment Institute Publication RP100 "Recommended Practices for the Installation of Underground Storage Tank Systems for Motor Vehicle Fueling";

(12)Petroleum Equipment Institute Publication RP800 "Recommended Practices for Installation of Bulk Storage Plants";

(13)Petroleum Equipment Institute Publication RP1000 "Recommended Practices for the Installation of Marina Fueling Systems";

(14)Petroleum Equipment Institute Publication RP1300 "Recommended Practices for the Design, Installation, Service, Repair, and Maintenance of Aviation Fueling Systems"; or

(15)Petroleum Equipment Institute Publication RP1400 "Recommended Practices for the Design and Installation of Fueling Systems for Emergency Generators, Stationary Diesel Engines and Oil Burner Systems".

C. Owners and operators shall not internally line ASTs as a means of repair.

D. Owners and operators shall tightness test a storage tank system that has been replaced, modified or repaired, prior to returning the system to service, in accordance with 20.5.111.1101 NMAC and Subparagraph (a) of Paragraph (3) of Subsection A of 20.5.111.1105 NMAC except as provided below:

(1) the repaired or modified tank is internally inspected in accordance with the current edition of an industry standard or code of practice approved in advance by the department; or

(2) owners and operators shall use an equivalent test method, which complies 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 in writing by the department.

E. Upon completion of a modification or repair of any cathodically protected storage tank system, owners and operators shall test the cathodic protection system in accordance with 20.5.110.1006 NMAC to ensure that it is operating properly.

F. Owners and operators of a storage tank system shall maintain records of each repair, replacement and modification until the storage tank system is permanently closed pursuant to 20.5.115 NMAC.

G. Owners and operators shall repair an above ground storage tank if an internal inspection determines that a release is occurring or that the tank bottom or shell thickness is below minimum thickness requirements. Owners and operators shall keep the records of internal inspections for the life of the tank. Minimum thickness requirements shall be determined by one of the following:

(1) manufacturer's specifications;

(2) 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; or

(3) minimum thickness for the tank bottom shall never be less than one half of the original bottom plate thickness and minimum thickness for the tank shall never be less than one-tenth inch.

H. Owners and operators shall meet all applicable installation requirements of 20.5.109 NMAC, including testing requirements, when repairing, replacing or modifying a storage tank system involves installing new components. If any tank or piping of a tank system is replaced, owners and operators shall follow all requirements for properly assessing the site for contamination in compliance with 20.5.115 NMAC prior to installing the new components.

I. Repairs to secondary containment of tanks, piping and containment sumps must be tested for tightness according to the manufacturer's instructions, a code of practice developed by a nationally recognized association or independent testing laboratory, or according to requirements established by the implementing agency within 30 days following the date of completion of the repair.

J. Within 30 days following any repair to spill or overfill prevention equipment, the repaired spill or overfill prevention equipment must be tested or inspected, as appropriate, in accordance with 20.5.110.1005 NMAC to ensure it is operating properly.
