General. All new and replacement underground storage tanks and piping systems shall be provided with secondary containment and continuous electronic interstitial monitoring, except as provided in par.
(b).
ATCP 93.500 Note
Note: This section is coordinated with the federal Energy Policy Act of 2005, which addresses secondary containment for federally regulated tanks or piping installed within 1,000 feet of any community water system or any potable drinking water well, and which requires interstitial monitoring for any associated double-wall tanks or piping.
ATCP 93.500(1)(b)
(b)
Exceptions. This subsection and sub.
(5) do not apply to any of the following:
ATCP 93.500(1)(b)1.
1. Any farm or residential underground storage tank system which has a capacity of less than 1,100 gallons and which is used for storing motor fuel for noncommercial purposes.
ATCP 93.500(1)(b)2.
2. Any underground storage tank system which has a capacity of less than 4,000 gallons and which is used for storing heating oil for consumptive use on the premises where stored.
ATCP 93.500(1)(c)1.1. Electronic interstitial monitoring installed in new tank or pipe systems after November 1, 2019, shall have the ability to generate a printed status report and alarm history report, except as provided in subd.

Flexible connections. Flexible piping approved under s.
ATCP 93.130 or listed metallic flex connectors shall be used in all of the following locations:

(c)
Reuse of tanks. Tanks that are moved from one underground location to another shall meet all of the following requirements:
ATCP 93.500(3)(c)1.
1. The integrity of the tank shall be assessed and certified by the manufacturer, or a registered professional engineer, stating that the tank still meets the construction requirements in s.
ATCP 93.250. The certification and a report of the assessment shall be included in the plan review documentation for the new installation.
ATCP 93.500(3)(c)2.
2. The integrity assessment required in subd. 1 shall occur after the tank has been removed.
ATCP 93.500(4)(a)(a) Underground storage tank systems shall be designed and constructed to allow access to all connections between the tank and piping, venting, and appurtenances that require maintenance, inspection or replacement.
ATCP 93.500 Note
Note: Piping elbows are an example of connections that do not need access because typically they do not need maintenance or inspection. Valves, extractor fittings, flex connectors, corrosion-protection test connections, and overfill prevention devices are examples of connections that need this access.
ATCP 93.500(4)(b)
(b) The means of access shall be sufficient in size to allow for installation, maintenance, and inspection of all system appurtenances.
ATCP 93.500(4)(c)
(c) The means of access shall allow sufficient clearance for proper drainage from surface water incursion.
ATCP 93.500(5)(a)1.1. When any underground product piping is installed as part of a new tank system or when 50 percent or more of a run is replaced, the piping shall be provided with approved secondary containment with non-discriminating electronic interstitial monitoring, except as specified in subd.
2., sub.
(1) (b), and s.
ATCP 93.300 (7).
ATCP 93.500 Note
Note: Underground fill piping is included in the piping that is addressed by this subdivision.
ATCP 93.500(5)(a)2.a.a. Sumps for new or replacement underground fill piping that does not drop vertically into a tank may be monitored visually on a monthly basis, instead of monitored with an electronic sensor.
ATCP 93.500(5)(a)2.b.
b. Secondary containment is not required for underground fill piping that drops vertically into a tank.
