How and When to Report Spills and Other Releases [40 CFR 302.6 and 40 CFR 355]

If you release a reportable quantity (RQ) of a CERCLA hazardous substance listed in Table 302.4 of 40 CFR 302 over a 24-hour period, you must report the release as described below:

According to 40 CFR 302.6, you must immediately notify the National Response Center (NRC) at 1-800-424-8802 or fax at 202-267-1322 as soon as you have knowledge of a CERCLA hazardous substance release from a facility or vessel in a quantity that equals or exceeds the RQ. If the release isn’t instantaneous, you must calculate the quantity released within any 24-hour period. See Table 302.4 for the list of hazardous substances and their RQs.

The following releases are exempt from the notification requirements described above:

CERCLA hazardous substance releases are also subject to the release reporting requirements of the Emergency Planning and Community Right-to-Know Act (or EPCRA, also known as SARA Title III). 40 CFR 355.33 states that if you have an RQ release of a CERCLA hazardous substance (Table 302.4) or of an extremely hazardous substance (Appendices A and B of 40 CFR 355) within a 24-hour period, the requirements of 40 CFR 355 Subpart C–Emergency Release Notification are triggered.

According to 40 CFR 355.31, a release is exempt from 40 CFR 355 release reporting if it meets any of the following criteria:

40 CFR 355.42 requires that you notify the following organizations:

The immediate notification [40 CFR 355.40(a)] must include the following information, as long as the retrieval of this information does not cause a delay in the notification:

You must provide a written follow-up emergency notice (or notices, as more information becomes available), as soon as practicable after the release. 40 CFR 355.40(b) states that your written notice must provide and update the information required in your immediate notification and also include the following:

The immediate notification, described in 40 CFR 355.40(a), must be oral. The follow-up emergency notification, described in 40 CFR 355.40(b), must be in writing with no particular written format specified in the regulations, although your SERC and LEPC may request a particular format or may request that you use a particular form for your written submission.

40 CFR 355.42(b) states that for releases occurring during transportation or from storage incident to transportation, you may meet the requirements of the subpart by notifying the 911 operator (or in the absence of a 911 emergency telephone number, the operator) of the immediate notification information listed in 40 CFR 355.40(a), and that you are not required under this subpart to submit a written follow-up notification, as described in 40 CFR 355.40(b), for such a release.

The following table will help you determine which release notification requirements apply to your release (the table does not apply to exempt releases):
