Note: As applied under sections
SPS 310.440 (2) and
(3), API 653 requires routine inspection of field-erected tanks, and STI SP001 requires periodic inspection of shop-built tanks, for evidence of leaks. Section
SPS 310.440 (6) requires submitting records of these inspections to the Department, for all tanks within a dike system that has walls or floor made of earth or masonry.
SPS 310.420(2)(f)1.1. Tanks may be installed within an existing dike system that has walls or floor made of earth or masonry only if all of the following conditions are met:

c. All other tanks within the dike system have overfill protection as specified in NFPA 30 section 21.7.1.
SPS 310.420(2)(f)2.
2. An existing dike system that has walls or floor made of earth or masonry may be expanded with materials which are similar to the materials in the existing walls and floor. After that expansion, tanks may be installed within the dike system only if all of the conditions in
subd. 1. a. to
c. are met.
SPS 310.420(2)(f)3.
3. Tanks within an existing dike system that has walls or floor made of earth or masonry may be converted from storing an unregulated substance to storing a regulated substance only if all of the following conditions are met:

A separation of at least 2 feet shall be provided between any new tank and the toe of any new or existing dike wall, and a minimum of 3 inches shall be provided between the bottom of any new tank and the dike floor, to allow for visual inspection of the exterior tank surface — except this 3-inch requirement does not apply to tanks that comply with
par. (e) 2. b. or
c., or where otherwise approved by the department.
SPS 310.420(2)(m)
(m) Drainage. Permanent containment structures shall be
designed with a manually controlled drainage system to permit the drainage of liquids resulting from leaks, spills and precipitation, such as a manually controlled pump or siphon or a manually controlled dike valve.
SPS 310.420(3)(a)(a) The department may accept secondary containment tanks of any size as providing acceptable secondary containment, except where dike systems are specifically required by this chapter.
SPS 310.420(3)(b)
(b) Secondary containment tanks shall be provided with an approved method of interstitial leak detection.
SPS 310.420(4)

SPS 310.430(1)
(1) Permanent vehicle collision protection shall be provided for any new or existing tank or system component that could result in a release of product when damaged, in any area where impact due to speed, turning, or backing of any type of motorized or self-propelled vehicle is likely to occur, except for tanks covered in
ss. SPS 310.610 (1) to
(3) and
310.630.
SPS 310.430 Note
Note: Sections
SPS 310.610 (1) to
(3) and
310.630 cover tank wagons, movable tanks, tank vehicles and aboveground farm tanks.
SPS 310.430 Note
Note: Vehicle collision protection is required for tanks located outside or inside a building in motorized-vehicle or self-propelled-equipment traffic areas, where impact resulting from vehicle speed, turning or backing is a risk factor. For example, vehicle collision protection is required for tanks located adjacent to traffic areas that accommodate public and fleet fueling, service and delivery vehicles, self-propelled construction and service equipment, and forklift equipment.
SPS 310.430 Note
Vehicle collision protection is not required for tanks adjacent to vehicle and equipment service bays where traffic patterns and speed would not be expected to impact the tank system.
SPS 310.430 Note
Vehicle collision protection is generally not required at a terminal where roadways are clearly defined, access is restricted to authorized personnel, and vehicle drivers are familiar with the layout of the facilities.
SPS 310.430(2)
(2) At least 24 inches of clearance shall be provided between a vehicle impact barrier and the tank or system component to be protected, unless otherwise approved by the department.
SPS 310.430(3)
(3) Impact barriers shall be designed to protect the tank or component from impact damage by the force of the largest vehicle routinely in the traffic area traveling at 5 miles per hour or at the average traveling speed, if higher than 5 miles per hour, except as provided in
sub. (4).
SPS 310.430(4)(a)(a) For impact barriers designed primarily to protect from the impact of automobiles, the portion determined to be most vulnerable to vehicle impact shall be capable of withstanding a single impact of 12,000-lb force applied at 10 miles per hour or equivalent impact energy.
SPS 310.430(4)(b)
(b) The impact shall be applied using a minimum 0.5-inch thick steel plate having a frontal surface area of 12 inches by 12 inches centered at 18 inches above grade.
SPS 310.430 Note
Note: For many applications, the Department will accept either D.O.T. guardrails or 4-inch steel posts filled with concrete, set at least 3 feet into the ground and spaced no more than 4 feet on center.
SPS 310.430(5)
(5) Vehicle impact barriers shall have a minimum height of 3 feet above grade or as acceptable to the authorized agent or the department.

(b) Initial inspections shall be conducted as required in Table 310.440.
SPS 310.440(2)(c)1.1. The agency conducting an API 653 inspection shall report all applicable information from the inspection on an API 653 tank inspection summary form supplied by the department.
SPS 310.440 Note
Note: Form ERS-10737-API 653 Tank Inspection Summary is available from the Division of Environmental and Regulatory Services at P.O. Box 7837, Madison, WI, 53707-7837, or at telephone (608) 266-7874, or from the Division's Web site at
http://dsps.wi.gov/er/ER-BST-FM-SPS310Forms.html.
SPS 310.440(2)(c)2.

SPS 310.440(2)(d)
(d) The tank owner or operator shall have the API 653 inspection summary on site and available for inspection within 30 days after receiving it from the agency that performed the inspection.
SPS 310.440(2)(e)
(e) For
tanks undergoing a transition from storing an unregulated substance to storing a regulated substance, any inspection in Table 310.440 that has not occurred shall be performed before putting the regulated substance into the tank. For the purposes of this paragraph, the service date is the date the tank was initially placed into service after construction.
SPS 310.440(3)
(3) Inspection of shop-built metallic aboveground storage tanks. SPS 310.440(3)(a)1.1. The owner or operator of all shop-built metallic aboveground fixed storage tanks shall have the tanks inspected in accordance with STI SP001, except as provided in
subd. 2.
SPS 310.440(3)(a)2.a.a. An alternate inspection procedure that provides equivalent environmental and fire safety protection may be used if accepted in writing by the department, or if developed by the certifying engineer for a facility in accordance with the federal spill prevention control and countermeasure regulations in
40 CFR 112.
SPS 310.440(3)(a)2.b.
b. This paragraph does not apply to tanks that have a capacity of less than 1,100 gallons.
SPS 310.440(3)(a)2.c.
c. This paragraph does not apply to heating oil tanks or to tanks at farms and construction projects.
SPS 310.440 Note
Note: STI SP001 requires monthly and annual inspections, and requires maintaining records of these inspections. For almost all ASTs that have a capacity of 5000 gallons or less, these inspections are only required to be visual. For most tanks that have a capacity of more than 5,000 gallons, the requirements include, but are not limited to, having a certified inspection every 20 years, consisting of a visual exam and spot, ultrasonic examination, with no requirement for an integrity pressure test. STI SP001 includes optional checklists that may be used for the required recordkeeping. These checklists and a compendium that contains further guidance for these inspections are available from the Division of Environmental and Regulatory Services at P.O. Box 7837, Madison, WI, 53707-7837, or at telephone (608) 266-7874, or from the Division's Web site at
http://dsps.wi.gov/er/ER-BST-FM-SPS310Forms.html.
