593. A manufacturing facility that produces electricity by burning coal stores the coal in an on-site stockpile that is exposed to the outside atmosphere. The facility meets the threshold criteria (40 CFR Section 372.22) for filing a Form R for the toxic chemical benzene. Since the stockpiled coal contains benzene and is exposed to the outside atmosphere, would all the benzene in the coal need to be reported on the Form R as a release to land on-site?
No. A facility does not have to report toxic chemicals contained in an on-site stockpile of material that is intended for otherwise use on-site as a release to land on-site. However, any toxic chemical that escaped to air or remains in the soil from the stockpile material (e.g., evaporative losses to air, material leached to the ground, etc.) must be reported as released to the environment on-site. Once a covered facility meets the criteria for filing a Form R under EPCRA section 313 for a toxic chemical (such as benzene), all releases of that chemical at the facility are to be reported. Releases of non-PBT chemicals from the stock pile will be eligible for the de minimis exemption.
