Hide details for Underground Storage Tanks (UST)Underground Storage Tanks (UST)
10/01/2004REGULATORY STATUS OF ENVIRONMENTAL MEDIA THAT HAS ENTERED A LEAKING UNDERGROUND STORAGE TANK (UST)Memo
 Description: Environmental media contaminated as a result of migration into a petroleum UST are not eligible for the exclusion in 40 CFR 261.4(b)(10). Contamination of media or debris entering a UST is not due to a petroleum release from a tank system; rather, the contamination results from the petroleum contents within the UST. Therefore, contaminated media or debris inside the UST would not qualify for the exclusion and should be managed as hazardous waste if it exhibits any characteristics of hazardous waste.
 
01/01/2004CONTAMINATED MEDIA AND DEBRIS FROM RESIDENTIAL HEATING OIL TANKSMemo
 Description: An UST storing heating oil for consumptive use on the premises where stored is not covered under the exclusion for petroleum-contaminated media and debris in 261.4(b)(10). These tanks are excluded from the definition of an UST in 280.12. Contaminated media and debris from a residential UST are household wastes as described in 261.4(b)(1).
 
01/01/1998PETROLEUM-CONTAMINATED DEBRIS FROM UST CLOSUREQuestion & Answer
 Description: The exclusion for petroleum-contaminated media and debris does not apply to sand that has been introduced into an underground storage tank (UST) for the purposes of closure. The exclusion was intended to cover contaminated environmental media such as soil, groundwater, surface water, and air that have become contaminated as a result of a release from an UST. Sand removed from an UST must be evaluated upon generation to determine if it is a hazardous waste.
 
11/27/1996APPLICABILITY OF 40 CFR PART 279 TO ON-SPECIFICATION USED OILMemo
 Description: On-specification used oil that will be burned for energy recovery is no longer subject to the used oil requirements once the person making the on-specification claim complies with the applicable marketer provisions. Used oil meeting specification that is refined or disposed is subject to the used oil requirements. The regulatory status of the on-specification oil must be reevaluated if some action is taken that may affect the properties of the oil. Blending used oil to meet specification is processing. Used oil storage may be covered under the Spill Prevention Control and Countermeasures (SPCC) regulations and the underground storage tank (UST) requirements.
 
11/01/1993RECYCLED USED OIL PROCESSING STANDARDS AS THEY APPLY TO ON-SITE RECYCLING OF USED OIL RECOVERED FROM A WASTEWATER TREATMENT SYSTEMMemo
 Description: Oil/water separation and recycling metal-working oil on-site are not processing if the recovered oil is not burned for energy recovery. Activities that are ancillary to the normal manufacturing process are not considered processing. USTs containing used oil are subject to Parts 279 and 280.
 
10/07/1993CLARIFICATION OF THE USE OF UNDERGROUND STORAGE TANKS TO CONTAIN HAZARDOUS WASTE SPILLSMemo
 Description: An underground tank used to contain a spill of hazardous waste solvent is a hazardous waste tank system. An underground tank used to contain a spill of reclaimed solvent not a hazardous waste tank system, but it may be subject to Part 280.
 
11/09/1990PETROLEUM-CONTAMINATED MEDIA AND DEBRIS DEFERRAL FROM THE TOXICITY CHARACTERISTICMemo
 Description: The petroleum contaminated media deferral does not apply to D001-D017. There is no need to run TCLP to determine if wastes are D018 - D043, provided the wastes are generated as part of UST corrective action.
 
10/01/1990REGULATORY STATUS OF PETROLEUM CONTAMINATED MEDIA AND DEBRIS UNDER THE TOXICITY CHARACTERISTIC UST TEMPORARY DEFERRALQuestion & Answer
 Description: The Section 261.4(b)(10) exclusion applies to media and debris from UST corrective action. The exclusion does not apply to sludge removed from UST during remediation. The exclusion does not apply to media and debris that exhibit the toxicity characteristic for D003-D017.
 
11/20/1986CONTAMINATED GROUND WATER AND VOLATILES FROM AIR STRIPPING, TREATMENT OFMemo
 Description: Contaminated groundwater is not a solid waste but must be handled as if it were a hazardous waste if it contains hazardous waste (contained in policy). Units handling such groundwater must be hazardous waste units. Such units may be exempt from permitting under the section 270.72 changes during interim status. Volatile organics released to the air during remediation are not solid wastes, but a release of hazardous constituents is subject to section 3008(h) corrective action authorities. The statute requires both air and groundwater contamination to be addressed. (SEE ALSO: 264/265 Subparts AA, BB, CC). A 1977 spill from a UST is subject to section 9003 corrective action is not subject to section 3008(h). The spraying of treated waste on land is land disposal and is subject to the land disposal restrictions (LDR).
 
10/31/1986USED OIL TANK CLASSIFICATIONMemo
 Description: Tanks storing used oil are not subject to the hazardous waste tank standards. An underground tank storing used oil must comply with the Part 280 UST standards.
