(a) Aboveground tanks located outdoors shall have secondary containment that complies with s. ATCP 93.420 (1) to (4) .

(b) Tanks located inside a building shall have secondary containment for 100 percent of the tank capacity if a leak from the storage tank could reach a floor drain, the exterior of the building or areas that pose an ignition hazard.

(7)   Underground tanks.

(a) General . Underground tanks for used-oil storage shall comply with the applicable portions of NFPA 30 and this section.

(b) Spill protection . For underground tanks that store used oil, spill protection is not required at any point other than the fill point, if the tank meets all of the following conditions:

1. The tank receives used oil in batches of 25 gallons or less by manual transfer.

2. The tank is emptied only by suction transfer.

(c) Corrosion protection . Corrosion protection shall be provided in accordance with s. ATCP 93.520 except this protection is not required for piping that is associated with an underground tank which stores used oil, provided the tank and piping meet all of the following conditions:

1. The tank receives used oil in batches of 25 gallons or less by manual transfer.

2. All piping that is underground is sloped at an angle of at least 30 degrees from horizontal between the point at which it enters the ground and the tank, to allow for the free flow of oil.

(d) Leak detection . Leak detection shall be provided in accordance with ss. ATCP 93.510 and 93.515 .

(8)   Tank closure and general administrative requirements.

(a) Aboveground tanks . Aboveground tanks that store used oil shall comply with ss. ATCP 93.440 to 93.470 .

(a) The tank is constructed of a durable material acceptable to the department.

(b) If located outside of a building, the tank has secondary containment acceptable to the department.

(c) If located inside a building, the tank has venting and fire prevention features acceptable to the department.

Note

Devices that burn used oil are regulated by the Commercial Building Code, chapters SPS 361 to 366, and the Fire Prevention Code, chapter SPS 314. The tank that stores the oil is regulated by this chapter. Microsoft Windows NT 6.1.7601 Service Pack 1 NFPA 31 section 12.9.1 requires tanks that supply used oil to an oil burner to be listed. Microsoft Windows NT 6.1.7601 Service Pack 1 See section ATCP 93.250 for minimum marking requirements for newly manufactured or constructed tanks. Microsoft Windows NT 6.1.7601 Service Pack 1 See section ATCP 93.260 for minimum separating distances between tanks and water supply wells. Microsoft Windows NT 6.1.7601 Service Pack 1 An oil-water separator connected to a floor drain may be used for all or a portion of the required secondary containment, depending on the system capacity. Microsoft Windows NT 6.1.7601 Service Pack 1 This section does not exempt the tank itself from corrosion protection requirements. Microsoft Windows NT 6.1.7601 Service Pack 1 Sections ATCP 93.440 to 93.470 address inspections; seldom-used and temporarily-out-of-service tanks; change in service to store a non-regulated substance; tank closures; tank-system site assessments; and confirming and responding to leaks, spills, overfills and releases. Microsoft Windows NT 6.1.7601 Service Pack 1 Sections ATCP 93.545 to 93.585 address seldom-used and temporarily-out-of-service tanks; change in service to store a non-regulated substance; tank system closures; conditions indicating releases; tank-system integrity assessments; tank-system site assessments; and responding to leaks, spills, overfills and releases.
