N.D. Admin. Code 33-24-05-1101

Current through Supplement No. 393, July, 2024
Section 33-24-05-1101 - Design and construction standards for new tank systems or components

Owners or operators must ensure 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. The owner or operator must obtain a written assessment, reviewed and certified by a qualified professional engineer, in accordance with subsection 4 of section 33-24-06-03, attesting that the tank system has sufficient structural integrity and is acceptable for the storing and treating of hazardous waste. This assessment must include, at a minimum, the following information:

1. Design standards for the construction of tanks or the ancillary equipment, or both.
2. Hazardous characteristics of the wastes to be handled.
3. 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:
a. Factors affecting the potential for corrosion, such as:
(1) Soil moisture content.
(2) Soil pH.
(3) Soil sulfides level.
(4) Soil resistivity.
(5) Structure to soil potential.
(6) Existence of stray electric current.
(7) Existing corrosion protection measures (for example, coating, cathodic protection).
b. The type and degree of external corrosion protection 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:
(1) Corrosion resistant materials of construction such as special alloys, fiberglass reinforced plastic;
(2) Corrosion resistant coating (such as epoxy, fiberglass) with cathodic protection (for example, impressed current or sacrificial anodes); and
(3) Electrical isolation devices such as insulating joints, flanges.
4. Design considerations to ensure that:
a. Tank foundations will maintain the load of a full tank.
b. Tank systems will withstand the effects of frost heave.
