Wisconsin Administrative Code › Department of Natural Resources › NR 600-699 - Environmental Protection - Hazardous Waste Management › Chapter NR 665 - Interim License Hazardous Waste Treatment, Storage And Disposal Facility Standards › Subchapter J - Tank Systems › Section NR 665.0192 - Design and installation of new tank systems or components

Current through June 24, 2024
(1) Owners or
				  operators of new tank systems or components shall 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 so that it will not collapse, rupture or fail. The owner or operator
				  shall obtain a written assessment reviewed and certified by a qualified
				  professional engineer in accordance with s.
				  NR
				  670.011(4) attesting that the system
				  has sufficient structural integrity and is acceptable for the storing and
				  treating of hazardous waste. This assessment shall include, at a minimum, all
				  of the following information:
(a) Design
				  standards according to which the tanks and ancillary equipment are or will be
				  constructed.
(b) Hazardous
				  characteristics of the wastes 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 is or will be in contact with the soil or with water, a
				  determination by a corrosion expert of all of the following:
1. Factors affecting the potential for
				  corrosion, including but not limited to, all of the following:
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 (e.g., piping).
g. Stray
				  electric current.
h. Existing
				  corrosion-protection measures (e.g., coating, cathodic protection).
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 or fiberglass-reinforced
				  plastic.
b. Corrosion-resistant
				  coating (such as epoxy or fiberglass) with cathodic protection (e.g., 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 (NACE) 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
					 (API) 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 affected by vehicular traffic, a determination
				  of design or operational measures that will protect the tank system against
				  potential damage.
(e) Design
				  considerations to ensure all of the following:
1. Tank foundations will maintain the load of
				  a full tank.
2. Tank systems will
				  be anchored to prevent flotation or dislodgement where the tank system is
				  placed in a saturated zone.
3. Tank
				  systems will withstand the effects of frost heave.
