§261.30. General. — Inbound Citations

(b) The notice required by 40 CFR 373.1 for the storage for one year or more of hazardous substances applies only when hazardous substances are or have been stored in quantities greater than or equal to 1000 kilograms or the hazardous substance's CERCLA reportable quantity found at 40 CFR 302.4, whichever is greater. Hazardous substances that are also listed under 40 CFR 261.30 as acutely hazardous wastes, and that are stored for one year or more, are subject to the notice requirement when stored in quantities greater than or equal to one kilogram.

(a) The name of the hazardous substance; the Chemical Abstracts Services Registry Number (CASRN) where applicable; the regulatory synonym for the hazardous substance, as listed in 40 CFR 302.4, where applicable; the RCRA hazardous waste number specified in 40 CFR 261.30, where applicable; the quantity in kilograms and pounds of the hazardous substance that has been stored for one year or more, or known to have been released, or disposed of, on the property, and the date(s) that such storage, release, or disposal took place.

(iii) Applicants are exempt from the requirements of paragraph (j)(7)(ii) of this section if they receive no more than fifteen kilograms per month of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e).

(2) Dischargers are exempt from the requirements of paragraph (p)(1) of this section during a calendar month in which they discharge no more than fifteen kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen kilograms of non-acute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification.

Subsequent months during which the Industrial User discharges more than such quantities of any hazardous waste do not require additional notification.
