  • Underground Storage Tanks in SPCC Plans

    If a gas station that has less than 42,000 gallons completely buried oil storage capacity and no aboveground oil storage capacity installs a new aboveground tank with a capacity greater than 1,320 gallons, must the facility’s Spill Prevention, Control, and Countermeasure (SPCC) Plan address the underground storage tanks (USTs) in…

  • Container capacity less than 55 gallons

    Do facilities need to consider containers that are less than 55 gallons for applicability under 40 CFR Part 112? No. The third column of page 47066 of the July 17, 2002 Preamble states that "You need only count containers of 55 gallons or greater in the calculation of the regulatory…

  • Oil-filled equipment capacity

    When counting against the 1,320 aboveground storage capacity threshold, would operational storage of oil (such as in a hydraulic press) be used? Oil which is contained in equipment is required to be factored into the storage capacity for the facility even though the oil may be only used for ancillary…

  • If your farm does not have fuel storage that will flow into US waters by a ditch, river, stream, or lake, do you have to prepare a SPCC Plan?

    No. EPA suggests you use a common sense approach. If one of your oil storage tanks leaks, and the spilled oil would not flow into navigable waters or adjoining shorelines, you do not have to prepare a Plan. Remember that you still have the responsibility to clean up any spilled…

  • Determining frequency of coordination activities

    The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). Are stationary sources responsible for determining if coordination activities should occur more often than annually? Ultimate responsibility…

  • Ground water pathways related to reasonably expected to discharge

    The SPCC Rule applies to facilities that could reasonably be expected to discharge into navigable waters (40 CFR §112.2(a)). Does a facility need to consider ground water pathways when determining if a discharge of oil could reasonably be expected to reach navigable waters? Owners and operators should consider whether on-site…

  • How Can I Reduce the Time Needed to Run the Nonroad Emission Factor Post-Processing Scripts?

    See More Frequent Questions about MOVES and Related Models . Very long run times are not unusual for Nonroad emission factor post-processing scripts, particularly with a large output database. To reduce script run time, we recommend doing the following: Reduce the size of your output database by choosing just the…

  • How do I Obtain the Populations for Each of the MOVES Source Types?

    See More Frequent Questions about MOVES and Related Models . To output vehicle populations, when setting up your RunSpec select the "Inventory" calculation type from the Scale panel and the "Population" activity option from the General Output panel of the MOVES GUI. The movesactivityoutput table in your MOVES output database…

  • How are Counties Mapped to Fuel Regions in MOVES? How Can I Substitute Alternate Fuel Formulations?

    See More Frequent Questions about MOVES and Related Models . The RegionCounty table in the MOVES default database maps each county to a MOVES fuel region (defined by regionCodeID). If you are conducting a County or Project Scale Run, you do not need to modify this table to use alternate…

  • 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…

  • Why Doesn't my Output Vehicle Miles Traveled (VMT) Match my Input VMT?

    See More Frequent Questions about MOVES and Related Models . This problem usually occurs when the run specification does not include all possible vehicle and fuel types. MOVES internally allocates the input VMT to each of the source types and fuel types and only reports the VMT for the fuel…

  • 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…
