  • Criteria for selecting alternative release scenarios

    As part of the hazard assessment, owners and operators of Program 2 and Program 3 covered processes must identify and analyze alternative release scenarios (40 CFR §68.28). What criteria should be used when selecting an alternative release scenario? The owner or operator of a stationary source subject to the risk…

  • Does the distance to endpoint start at the process or stationary source boundary?

    When selecting the worst-case release scenario for Program 2 and 3 processes as required by 40 CFR §68.25, a stationary source owner or operator must analyze the release scenario that results in the greatest distance to an endpoint. Does the "greatest distance to an endpoint" refer to the greatest total…

  • Using meteorological station data for off-site consequence analyses

    For the purpose of the offsite consequence analyses required under 40 CFR Part 68, Subpart B, there are several instances in which data gathered at a local meteorological station may be used to establish the modeling parameters of wind speed, atmospheric stability, temperature, and humidity for the stationary source. How…

  • Underground storage tank off-site impacts to groundwater, drinking water, or soil

    For the worst-case and alternative release scenarios of an underground storage tank, should I consider any impact on groundwater, drinking water, or soil? No. As part of the worst-case and alternative release scenarios, you need to define the offsite impacts to the environment (40 CFR §68.33) by listing the environmental…

  • Worst-case release from smaller process with larger distance to endpoint

    The owner or operator of a stationary source covered by the risk management program regulations must conduct a worst-case release scenario analysis as part of the required hazard assessment (40 CFR §68.25). The worst-case release is defined as the release of the largest quantity of a regulated substance from a…

  • How will the volume of corn ethanol produced above the grandfathering threshold be treated?

    See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . For grandfathered facilities, only the baseline volumes are exempt from the 20 percent GHG reduction requirement Thus, RINs may be generated for baseline volumes of fuel regardless of lifecycle greenhouse gas emissions performance. Volumes of fuel produced above…

  • How long will the grandfathering provision be effective? Once a grandfathered producer registers and completes their engineering review, will their baseline volume ever need to meet the 20% GHG reduction requirement?

    See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . If a facility meets the requirements for exemption from the 20% GHG reduction requirement pursuant to 40 CFR 80.1403(c ) or (d), then the baseline volume of renewable fuel produced by that facility is exempt from the 20%…
