(b) These setbacks do not apply where piping or dispensers are being replaced without replacing the tank.
ATCP 93.260(1)(c)
(c) These setbacks do not apply where shorter setbacks are specified by the department of natural resources.
ATCP 93.260 Note
Note: The department of natural resources administers separating distances for proposed
public community water supply wells regulated under ch.
NR 811, and those distances may differ from the distances in Table 93.260. See footnote 4 under Table 93.260 for DNR requirements about separating distances for proposed and already-installed private water supply wells regulated under ch.
NR 812.
ATCP 93.260 Note
Note: Longer setback distances may be imposed through local wellhead-protection requirements.
Table 93.260
1 Any reference in this column to a UST or AST “system” means both the tank and any product piping connected to it have the subsequently specified features.
2 The setback in this column is at least 1200 feet if any associated fueling area is not on a concrete surface, and any associated AST is not on a concrete surface, except this requirement does not apply to the setback for a one- or two-family residential heating oil AST.
3 The setback in this column is at least 100 feet if any associated fueling area is not on a concrete surface, and any associated AST is not on a concrete surface, except this requirement does not apply to the setback for a one- or two-family residential heating oil AST.
4 Any setback in this column that is less than 100 feet, other than the 25-foot setback for one- and two-family residences, may be utilized only after obtaining a variance or other approval from the department of natural resources, except a variance or other approval is not required for an AST that has a capacity of 1500 gallons or less.
5 This distance may be reduced by 50 percent if all of the following features are provided and maintained in addition to the features in the tank-type column: tank system construction of corrosion-resistant material, such as fiber-reinforced plastic, or steel with a fiber-reinforced plastic wrap or jacket; non-discriminating sump sensors; testable secondary containment spill bucket; continuous electronic pressure, vacuum, or liquid-filled interstitial monitoring with automatic system shut-down; audible and visual high-level alarm at 90 percent full, and automatic shut-off at 95 percent; all fueling area protected by canopy; and downspouts for drainage of rainwater do not discharge into a fueling area.
6 This distance may be reduced by 50 percent if all of the following features are provided and maintained in addition to the features in the tank-type column: either continuous non-discriminating electronic interstitial monitoring for double wall, or continuous non-discriminating electronic sensor for other secondary containment; audible and visual high-level alarm at 90 percent full, and either automatic shutoff at 95 percent or no latch-open device is used with any manual-shutoff nozzle; all dispensing by suction pump fuel transfer; all motor vehicle fueling limited to private or fleet use; all fueling area protected by canopy; and downspouts for drainage of rainwater do not discharge into a fueling area.
7 This reduced setback is only permitted for emergency or standby power systems that are operated by the same facility which operates the well, and only if all of the following features are provided and maintained in addition to the features in the tank-type column: audible and visual high-level alarm at 90 percent full, and either automatic shutoff at 95 percent or no latch-open device is used with any manual-shutoff nozzle. This setback may be reduced further where approved in writing by the department, upon submittal of an explanation of why reducing the setback is needed, along with demonstration that additional features will be included which will provide adequate protection for the well.
