  • 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…

  • Can MOVES Report Output in Terms of Fuel Consumption?

    See More Frequent Questions about MOVES and Related Models . Although gallons of fuel consumed are not reported by MOVES, the factors used to convert total energy consumption (a MOVES reporting option) to gallons of fuel are contained in the FuelSubtype table (energy content, reported in kilojoules per gram of…

  • How do I use MOVES at Project Scale?

    See More Frequent Questions about MOVES and Related Models . The MOVES model can estimate emissions at national, county or project scale. Project scale is useful for estimating an individual transportation project like an intersection or transit project, but it requires detailed inputs that describing the vehicle population and activity…

  • How Can I Determine the Effect of Speed on Vehicle Emissions?

    See More Frequent Questions about MOVES and Related Models . MOVES can be run in either “Inventory” or “Emission Rates” mode. With Emission Rates, MOVES reports emission rates for the 16 average speed bins used by MOVES for each hour of the day and additional emission rate output that may…

  • 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…

  • Does MOVES Incorporate Anticipated Improvements in VOC Emission Factors Resulting from Improved Fuel Economy?

    See More Frequent Questions about MOVES and Related Models . Changes in fuel consumption affect VOC emissions by reducing refueling vapor losses and spillage. Other emissions (such as sulfates) are also affected by fuel consumption. MOVES incorporates changes due to fuel economy requirements that were finalized as of the date…

  • Can I use MOVES to Model Emissions from Vehicles in other Countries?

    See More Frequent Questions about MOVES and Related Models . The MOVES model was designed specifically to model the emissions from vehicles and equipment designed to meet emission standards in the United States. There are considerable challenges to adapting the MOVES framework to other nations, primarily around the need for…

  • How can I run MOVES3 for the entire U.S or for an entire year?

    See More Frequent Questions about MOVES and Related Models . The most accurate national MOVES runs are done for every county and hour and then averaged together in the output, but, depending on your intended use of the results, it’s also possible to pre-aggregate the MOVES inputs to run the…

  • 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…

  • What are the features available on the MOVES “Advanced Features” panel, and when would I use them?

    The MOVES graphical user interface (GUI) includes a panel for “Advanced Features,” which allows modelers to edit RunSpec inputs for preaggregation options and select input databases created by MOVES tools. The panel also includes some options that are obsolete or intended only for MOVES testing and development work. Each of…
