North Dakota Administrative Code › Title 33.1 - Department of Environmental Quality › Article 33.1-24 - Hazardous Waste Management › Chapter 33.1-24-05 - Standards for Treatment, Storage, and Disposal Facilities and for the Management of Specific Hazardous Wastes and Specific Types of Hazardous Waste Management Facilities › TANK REQUIREMENTS › Section 33.1-24-05-105 - Design and installation of new tank systems or components

Current through Supplement No. 393, July, 2024
1. Owners or
				  operators of new tank systems or components shall obtain and submit to the
				  department, at time of submittal of part B application information, a written
				  assessment, reviewed and certified by a qualified professional engineer, in
				  accordance with subsection 4 of section
				  33.1-24-06-03, attesting that
				  the tank system has sufficient structural integrity and is acceptable for the
				  storing and treating of hazardous waste. The assessment must show that the
				  foundation, structural support, seams, connections, and pressure controls (if
				  applicable) are adequately designed and that the tank system has sufficient
				  structural strength, compatibility with the wastes to be stored or treated, and
				  corrosion protection to ensure that it will not collapse, rupture, or fail.
				  This assessment, which will be used by the department to review and approve or
				  disapprove the acceptability of the tank system design, must include, at a
				  minimum, the following information:
a. Design
				  standards according to which tanks or the ancillary equipment, or both, are
				  constructed;
b. Hazardous
				  characteristics of the waste to be handled;
c. For new tank systems or components in
				  which the external shell of a metal tank or any external metal component of the
				  tank system will be in contact with the soil or with water, a determination by
				  a corrosion expert of:
(1) Factors affecting
				  the potential for corrosion, including:
(a)
				  Soil moisture content;
(b) Soil
				  pH;
(c) Soil sulfides
				  level;
(d) Soil
				  resistivity;
(e) Structure to soil
				  potential;
(f) Influence of nearby
				  underground metal structures (for example, piping);
(g) Existence of stray electric current;
				  and
(h) Existing corrosion
				  protecting measures (for example, coating, cathodic protection); and
(2) The type and degree of
				  external corrosion protection that are needed to ensure the integrity of the
				  tank system during the use of the tank system or component, consisting of one
				  or more of the following:
(a)
				  Corrosion-resistant materials of construction, such as special alloys,
				  fiberglass reinforced plastic, etc.;
(b) Corrosion-resistant coating (such as
				  epoxy, fiberglass, etc.) with cathodic protection (for example, impressed
				  current or sacrificial anodes);
(c)
				  Electrical isolation devices, such as insulating joints and flanges;
Note: The practices described in the national association
					 of corrosion engineers standard, "Recommended Practice (RP-02-85) Control of
					 External Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid
					 Storage Systems", and the American petroleum institute publication 1632,
					 "Cathodic Protection of Underground Petroleum Storage Tanks and Piping
					 Systems", may be used, where applicable, as guidelines in providing corrosion
					 protection for tank systems.
(d) For underground tank system components
				  that are likely to be adversely affected by vehicular traffic, a determination
				  of design or operational measures that will protect the tank system against
				  potential damage; and
(e) Design
				  considerations to ensure that:
[1] Tank
				  foundations will maintain the load of a full tank;
[2] Tank systems will be anchored to prevent
				  floatation or dislodgment where the tank system is placed in a saturated zone,
				  or is located within a seismic fault zone subject to the standards of
				  subsection 1 of section
				  33.1-24-05-09; and
[3] Tank systems will withstand the effects
				  of frost heave.
