North Dakota Administrative Code › Title 33.1 - Department of Environmental Quality › Article 33.1-24 - Hazardous Waste Management › Chapter 33.1-24-08 - Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks › Section 33.1-24-08-10 - Performance standards for new underground storage tank systems

Current through Supplement No. 393, July, 2024
In order to prevent releases due to structural failure,
				  corrosion, or spills and overfills for as long as the underground storage tank
				  system is used to store regulated substances, all owners and operators of new
				  underground storage tank systems must meet the following requirements. In
				  addition, except for suction piping that meets the requirements of
				  subparagraphs a through e of paragraph 2 of subdivision a of subsection 2 of
				  section 33.1-24-08-31, tanks and piping
				  installed or replaced after January 1, 2009, must be secondarily contained and
				  use interstitial monitoring in accordance with subsection 7 of section
				  33.1-24-08-33. Secondary
				  containment must be able to contain regulated substances leaked from the
				  primary containment until they are detected and removed and prevent the release
				  of regulated substances to the environment at any time during the operational
				  life of the underground storage tank system. For cases where the piping is
				  considered to be replaced, the entire piping run must be secondarily
				  contained.
1.
Tanks.
Each
				tank must be properly designed and constructed, and any portion underground
				that routinely contains product must be protected from corrosion in accordance
				with a code of practice developed by a nationally recognized association or
				independent testing laboratory as specified below:
a. The tank is constructed of
				fiberglass-reinforced plastic.
NOTE: The following codes of practice may be used to comply
				  with this subdivision: Underwriters Laboratory Standard 1316,
				  "Glass-Fiber-Reinforced Plastic Underground Storage Tanks for Petroleum
				  Products Alcohols, and Alcohol-Gasoline Mixtures"; or Underwriters Laboratories
				  of Canada S615, "Standard for Reinforced Plastic Underground Tanks for
				  Flammable and Combustible Liquids".
b. The tank is constructed of steel and
				cathodically protected in the following manner:
(1) The tank is coated with a suitable
				dielectric material;
(2)
				Field-installed cathodic protection systems are designed by a corrosion
				expert;
(3) Impressed current
				systems are designed to allow determination of current operating status as
				required in subsection 3 of section
				33.1-24-08-21; and
(4) Cathodic protection systems are operated
				and maintained in accordance with section
				33.1-24-08-21 or according to
				guidelines established by the department.
NOTE: The following codes of practice may be used to comply
				  with this subdivision: Steel Tank Institute "Specification STI-P3®
				  Specification and Manual for External Corrosion Protection of Underground Steel
				  Storage Tanks"; Underwriters Laboratories Standard 1746, "External Corrosion
				  Protection Systems for Steel Underground Storage Tanks"; Underwriters
				  Laboratories of Canada S603, "Standard for Steel Underground Tanks for
				  Flammable and Combustible Liquids", and S603.1, "Standard for External
				  Corrosion Protection Systems for Steel Underground Tanks for Flammable and
				  Combustible Liquids", and S631, "Standard for Isolating Bushings for Steel
				  Underground Tanks Protected with External Corrosion Protection Systems"; Steel
				  Tank Institute Standard F841, "Standard for Dual Wall Underground Steel Storage
				  Tanks"; or NACE International Standard Practice SP 0285, "External Corrosion
				  Control of Underground Storage Tank Systems by Cathodic Protection"; and
				  Underwriters Laboratories Standard 58, "Standard for Steel Underground Tanks
				  for Flammable and Combustible Liquids".
c. The tank is constructed of steel and clad
				or jacketed with a noncorridble material.
NOTE: The following codes of practice may be used to comply
				  with this subdivision: Underwriters Laboratories Standard 1746, "External
				  Corrosion Protection Systems for Steel Underground Storage Tanks"; Steel Tank
				  Institute ACT-100® Specification F894, "Specification for External
				  Corrosion Protection of FRP Composite Steel Underground Storage Tanks"; Steel
				  Tank Institute ACT-100-U® Specification F961, "Specification for External
				  Corrosion Protection of Composite Steel Underground Storage Tanks"; or Steel
				  Tank Institute Specification F922, "Steel Tank Institute Specification for
				  Permatank®".
d. The
				tank is constructed of metal without additional corrosion protection measures
				provided that:
(1) The tank is installed at a
				site that is determined by a corrosion expert not be corrosive enough to cause
				it to have a release due to corrosion during its operating life; and
(2) Owners and operators maintain records
				that demonstrate compliance with the requirements of paragraph 1 of this
				subdivision for the remaining life of the tank.
e. The tank construction and corrosion
				protection are determined by the department to be designed to prevent the
				release or threatened release of any stored regulated substance in a manner
				that is no less protective of human health and the environment than
				subdivisions a through d.
