  • Secondary containment for oil-filled operation equipment under SPCC

    On December 26, 2006, EPA provided an optional alternative to the general secondary containment requirements in 40 CFR §112.7(c) for qualified oil-filled operational equipment ( 71 FR 77266 ). Because the alternative is optional, an owner or operator could choose to comply with the existing SPCC requirements to provide general…

  • What sources make up the Tier 1 categories used in the emissions trends?

    Tier 1 categories are assigned by source classification codes (SCCs) that are the most specific processes available in the NEI. The latest SCC list with the Tier 1 assignments can be downloaded from the EPA SCC website in Comma Separate Values (CSV) format.

  • What is the cause of the large decrease in electric utility emissions, particularly sulfur dioxide, starting in 1995?

    SO2 emissions reductions from utilities during this time are primarily attributed to the impacts of the acid rain program. As described on EPA’s Acid Rain Program web page, Phase 1 of this program began in 1995 and affected 263 units at 110 most coal-burning electric utility plants in 21 eastern…

  • SPCC requirements for transfer areas associated with exempt USTs

    Gas stations typically are not subject to the SPCC Rule because completely buried storage tanks subject to 40 CFR Part 280 or 281 are exempt per §112.1(d)(4). However, a gas station would be subject to the SPCC Rule if it has more than 1,320 gallons of oil in aggregate above…

  • Do the changes in the 2006 Amendments apply to oil-filled manufacturing equipment?

    No. The amendment does not change any requirements for oil-filled manufacturing equipment. Oil-filled manufacturing equipment remains subject to the SPCC requirements (including those for containment), but an owner/operator may determine that secondary containment is impracticable and comply with the alternative measures in section 112.7(d).

  • What is an oil spill contingency plan?

    Instead of providing secondary containment for qualified oil-filled operational equipment, an owner or operator may prepare an oil spill contingency plan and a written commitment of manpower, equipment, and materials to quickly control and remove discharged oil. He/she must also have an inspection or monitoring program for the equipment to…

  • Secondary containment requirements for mobile refuelers

    What secondary containment requirements apply to mobile refuelers? General secondary containment requirements in §112.7(c) still apply to mobile refuelers at SPCC regulated facilities. General secondary containment should be designed to address the most likely discharge from the container and from oil transfers into or from the mobile refueler. The general…

  • What changes did EPA finalize to the SPCC Rule in December 2006?

    The revised rule modifies requirements for facilities with smaller oil storage capacity and specific types of oil-filled operating equipment. If a facility has 10,000 gallons or less in aggregate aboveground oil storage capacity and the facility meets the oil discharge history criteria, then an owner/operator of a facility may prepare…

  • Eligibility for qualified oil-filled operational equipment in event of a discharge

    Does a facility automatically lose eligibility for the option for qualified oil-filled operational equipment if the equipment has an oil discharge? No. Facilities that choose this alternative and later have a reportable oil discharge from qualified oil-filled operational equipment do not automatically lose eligibility. However, the spill reporting requirements would…

  • Can qualified facilities also use the alternative requirements for qualified oil-filled operational equipment?

    Yes. Facilities that meet the criteria for qualified facilities and qualified oil-filled operational equipment may benefit from both of the alternative approaches. Since an impracticability determination is not necessary for qualified oil-filled operational equipment, the owner/operator can self-certify the SPCC Plan and is not required to have a PE develop…

  • SPCC change in ownership

    If there is a change in ownership at a facility, can the facility operate under the same SPCC Plan without the certification from a professional engineer (PE)? If no change in procedures has been made, it may still be feasible to operate under the existing SPCC Plan. The information in…

  • Liability of oil retailers at SPCC regulated farm

    If a farm is out of compliance of Spill Prevention, Control, and Countermeasure (SPCC) regulations and is checked by EPA and/or has a spill, is the retailer that filled the tank liable? No, EPA considers the oil tank owner responsible for lack of compliance.

  • Secondary containment calculations in SPCC Plan

    The SPCC regulations in 40 CFR §112.7(c) require facilities to provide appropriate containment or diversionary structures or equipment to prevent discharges as described in §112.1(b). Does a facility's SPCC Plan have to include calculations to demonstrate compliance with the §112.7(c) general secondary containment requirements? EPA does not require facilities to…

  • What are the specifications for bulk storage secondary containment systems?

    For purposes of the SPCC requirements, "secondary containment for bulk storage facilities must be constructed to at least provide for the capacity of the largest single tank with sufficient freeboard for precipitation. EPA believes that the proper standard of "sufficient freeboard" to contain precipitation is that amount necessary to contain…
