NR 665.0191(2)(e)1.1. For non-enterable underground tanks, this assessment shall consist of a leak test that is capable of taking into account the effects of temperature variations, tank end deflection, vapor pockets and high water table effects. NR 665.0191(2)(e)2.2. For other than non-enterable underground tanks and for ancillary equipment, this assessment shall be either a leak test, as described in subd. 1., or an internal inspection or other tank integrity examination certified by a qualified professional engineer in accordance with s. NR 670.011 (4) that addresses cracks, leaks, corrosion, and erosion. NR 665.0191 NoteNote: The practices described in the American Petroleum Institute (API) Publication, Guide for Inspection of Refinery Equipment, Chapter XIII, “Atmospheric and Low-Pressure Storage Tanks”, 4th edition, 1981, may be used, where applicable, as guidelines in conducting the integrity examination of an other than non-enterable underground tank system.
NR 665.0191(3)(3) Tank systems that store or treat materials that become hazardous wastes subsequent to March 1, 1991 shall conduct this assessment within 12 months after the date that the waste becomes a hazardous waste. NR 665.0191(4)(4) If, as a result of the assessment conducted in accordance with sub. (1), a tank system is found to be leaking or unfit for use, the owner or operator shall comply with the requirements of s. NR 665.0196. NR 665.0191 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; CR 16-007: am. (1), (2) (e) 2. Register July 2017 No. 739, eff. 8-1-17. NR 665.0192NR 665.0192 Design and installation of new tank systems or components. NR 665.0192(1)(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: NR 665.0192(1)(a)(a) Design standards according to which the tanks and ancillary equipment are or will be constructed. NR 665.0192(1)(c)(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: NR 665.0192(1)(c)1.1. Factors affecting the potential for corrosion, including but not limited to, all of the following: NR 665.0192(1)(c)2.2. 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: NR 665.0192(1)(c)2.a.a. Corrosion-resistant materials of construction such as special alloys or fiberglass-reinforced plastic. NR 665.0192(1)(c)2.b.b. Corrosion-resistant coating (such as epoxy or fiberglass) with cathodic protection (e.g., impressed current or sacrificial anodes). NR 665.0192 NoteNote: 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.
NR 665.0192(1)(d)(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. NR 665.0192(1)(e)2.2. Tank systems will be anchored to prevent flotation or dislodgement where the tank system is placed in a saturated zone.
