NR 667.0193NR 667.0193 What testing shall I do? Test all new tanks and ancillary equipment for tightness before you place them in use. If you find a tank system that is not tight, perform all repairs necessary to remedy the leak or leaks in the system before you cover, enclose or place the tank system into use.

NR 667.0194(1)(1) Support and protect ancillary equipment against physical damage and excessive stress due to settlement, vibration, expansion or contraction.

NR 667.0194(2)(2) Provide the type and degree of corrosion protection recommended by an independent corrosion expert, based on the information provided under s. NR 667.0191 (3), to ensure the integrity of the tank system during use of the tank system. An independent corrosion expert shall supervise the installation of a corrosion protection system that is field fabricated to ensure proper installation.

NR 667.0194(3)(3) Obtain and keep at the facility written statements by those persons required to certify the design of the tank system and to supervise the installation of the tank system as required in subs. (1) and (2) and ss. NR 667.0192 and 667.0193. The written statement shall attest that the tank system was properly designed and installed and that you made repairs under ss. NR 667.0192 and 667.0193. These written statements shall also include the certification statement as required in s. NR 670.011 (4).

NR 667.0195NR 667.0195 What are the secondary containment requirements? To prevent the release of hazardous waste or hazardous constituents to the environment, provide secondary containment that meets the requirements of this section for all new and existing tank systems.

NR 667.0195(1)(1) Secondary containment systems shall be:

NR 667.0195(1)(a)(a) Designed, installed and operated to prevent any migration of wastes or accumulated liquid out of the system to the soil, groundwater, or surface water at any time during the use of the tank system.

NR 667.0195(1)(b)(b) Capable of detecting and collecting releases and accumulated liquids until the collected material is removed.

NR 667.0195(2)(2) To meet the requirements of sub. (1), secondary containment systems shall be, at a minimum:

NR 667.0195(2)(a)(a) Constructed of or lined with materials that are compatible with the waste or wastes to be placed in the tank system and shall have sufficient strength and thickness to prevent failure owing to pressure gradients (including static head and external hydrological forces), physical contact with the waste to which it is exposed, climatic conditions and the stress of daily operation (including stresses from nearby vehicular traffic).

NR 667.0195(2)(b)(b) Placed on a foundation or base capable of providing support to the secondary containment system, resistance to pressure gradients above and below the system and capable of preventing failure due to settlement, compression, or uplift.

NR 667.0195(2)(c)(c) Provided with a leak-detection system that is designed and operated so that it will detect the failure of either the primary or secondary containment structure or the presence of any release of hazardous waste or accumulated liquid in the secondary containment system within 24 hours.

NR 667.0195(2)(d)(d) Sloped or otherwise designed or operated to drain and remove liquids resulting from leaks, spills, or precipitation. Remove spilled or leaked waste and accumulated precipitation from the secondary containment system within 24 hours, or as promptly as possible, to prevent harm to human health and the environment.
