  • Changing from a Program 2 or 3 process to a Program 1 process

    If five years have passed since the last accident involving a covered process, and that process meets the other two requirements identified under 40 CFR §68.10(b) for Program 1 eligibility, could that process become a Program 1 process even if it had previously been identified as a Program 2 or 3

  • Can a facility divide a process when assigning program levels?

    My process includes a series of interconnected units, as well as several storage vessels that are co-located. Several sections of the process could qualify for Program 1. Can I divide my process into sections for the purpose of assigning Program levels? No, you cannot subdivide a process for this

  • If a covered process has an accident, when does it lose eligibility for Program 1 status?

    A process covered under 40 CFR Part 68 is eligible for Program 1 requirements if it meets all of the criteria listed at 40 CFR §68.10(b). Those criteria include a requirement that the process cannot have had an accidental release of a regulated substance that led to offsite death, injury, or

  • If a stationary source has processes ineligible for Program 1, are all processes ineligible?

    If a stationary source has several processes that are covered under 40 CFR Part 68, and some of those processes have had an accidental release within the past five years (effectively making those processes ineligible for Program 1 status), are the individual processes from which no accidents have

  • Change of owner and RMP facility ID number

    If a facility is sold to a new owner, does it keep its' original RMP Facility ID number? Yes. The facility will keep the ID number assigned by EPA.

  • Facility ID number and re-registering a facility

    If a facility deregisters, then reregisters, should the facility use the original RMP Facility ID or will it be assigned a new ID? The facility should use the original ID assigned by EPA.

  • Resubmission of RMP for a facility that previously deregistered

    A covered facility deregisters its RMP because it no longer has more than a threshold quantity of a regulated substance in a covered process. If the facility becomes subject to the CAA §112(r) risk management program regulations at a later date and submits a new RMP, should the facility submit it as

  • Accidental releases from non-covered processes

    Should the owner or operator include accidental releases from processes containing listed substances below the threshold quantity in the five-year accident history required under the hazard assessment provisions of 40 CFR Part 68, Subpart B, and in the incident investigation requirements under 40

  • Do I have to report accidents that resulted in medical treatment?

    I had a release where several people were treated at the hospital and released; they attributed their symptoms to exposure. We do not believe that their symptoms were in fact the result of exposure to the released substance. Do we have to report these as offsite impacts? Yes, you should report them

  • Administrative controls considered when determining worst-case release quantity

    For the purpose of analyzing the worst-case release scenario required as part of the hazard assessment at 40 CFR Part 68, Subpart B, the worst-case release quantity is identified as the greatest amount held in a single vessel or pipe, taking into account administrative controls that limit the

  • Can I use any previous three year meteorological data for worst case scenario?

    I am trying to complete my worst case release scenario for the Risk Management Plan under §68.25. I understand that I am required to use a wind speed of 1.5 m/s and F atmospheric stability class as specified in §68.22(b), unless I can prove that at no time over the previous three years were the

  • 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

  • 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

  • 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

  • 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
