Summary

The EPA Administrator must publish a list of extremely hazardous substances and set amounts that trigger planning rules for them. The list must match the one in Appendix A of the “Chemical Emergency Preparedness Program Interim Guidance” published in November 1985. Within 30 days after October 17, 1986, the Administrator must issue interim rules giving a threshold planning quantity for each listed substance and start making final rules. Thresholds can be set for groups of chemicals or types of facilities. If no interim rule is issued within those 30 days, the default threshold for that substance is 2 pounds until a rule is published. The Administrator can change the list or thresholds later, considering toxicity, reactivity, volatility, dispersability, combustibility, and flammability. “Toxicity” includes any short- or long-term health effect from a short exposure. A facility is covered if it has more of a listed substance than the threshold. A Governor or State emergency response commission can add other facilities after public notice and comment and must tell the facility. Facility owners or operators must tell the State emergency response commission within seven months after October 17, 1986 if their site is covered. Later, they must notify the State commission and the local emergency planning committee within 60 days whenever they first bring a listed substance over the threshold or when a revised list makes the facility covered. The State emergency response commission must tell the Administrator about every facility notice it gets and every facility it adds.

(B)The threshold planning quantities may, at the Administrator’s discretion, be based on classes of chemicals or categories of facilities.
(C)If the Administrator fails to publish an interim final regulation establishing a threshold planning quantity for a substance within 30 days after October 17, 1986, the threshold planning quantity for the substance shall be 2 pounds until such time as the Administrator publishes regulations establishing a threshold for the substance.
(4)Revisions
The Administrator may revise the list and thresholds under paragraphs (2) and (3) from time to time. Any revisions to the list shall take into account the toxicity, reactivity, volatility, dispersability, combustability, or flammability of a substance. For purposes of the preceding sentence, the term “toxicity” shall include any short- or long-term health effect which may result from a short-term exposure to the substance.
(b)Facilities covered
(1)Except as provided in section 11004 of this title, a facility is subject to the requirements of this subchapter if a substance on the list referred to in subsection (a) is present at the facility in an amount in excess of the threshold planning quantity established for such substance.
(2)For purposes of emergency planning, a Governor or a State emergency response commission may designate additional facilities which shall be subject to the requirements of this subchapter, if such designation is made after public notice and opportunity for comment. The Governor or State emergency response commission shall notify the facility concerned of any facility designation under this paragraph.
(c)Emergency planning notification
Not later than seven months after October 17, 1986, the owner or operator of each facility subject to the requirements of this subchapter by reason of subsection (b)(1) shall notify the State emergency response commission for the State in which such facility is located that such facility is subject to the requirements of this subchapter. Thereafter, if a substance on the list of extremely hazardous substances referred to in subsection (a) first becomes present at such facility in excess of the threshold planning quantity established for such substance, or if there is a revision of such list and the facility has present a substance on the revised list in excess of the threshold planning quantity established for such substance, the owner or operator of the facility shall notify the State emergency response commission and the local emergency planning committee within 60 days after such acquisition or revision that such facility is subject to the requirements of this subchapter.
(d)Notification of Administrator
The State emergency response commission shall notify the Administrator of facilities subject to the requirements of this subchapter by notifying the Administrator of— (1)
(2)each facility designated by the Governor or State emergency response commission under subsection (b)(2).
