(a) This part (40 CFR part 355) establishes requirements for a facility to provide information necessary for developing and implementing State and local chemical emergency response plans, and requirements for emergency notification of chemical releases. This part also lists Extremely Hazardous Substances (EHSs) and Threshold Planning Quantities (TPQs) in Appendices A and B, which are used in determining if you are subject to these requirements.
(b) This part is written in a special format to make it easier to understand the regulatory requirements. Like other Environmental Protection Agency (EPA) regulations, this part establishes enforceable legal requirements. Information considered non-binding guidance under EPCRA is indicated in this regulation by the word “note” and a smaller typeface. Such notes are provided for information purposes only and are not considered legally binding under this part.
Throughout this part, “you,” “I,” and “your” refer to the owner or operator of a facility.
The definitions of key words used in this part are in §355.61. It is important to read the definitions for these key words because the definition explains the word's specific meaning associated with the regulations in this part.
You must comply with the emergency planning requirements in this subpart if your facility meets either of the following two conditions:
(a) Any extremely hazardous substance (EHS) is present at your facility in an amount equal to or greater than its threshold planning quantity (TPQ), or
(b) Your facility has been designated for emergency planning purposes, after public notice and opportunity for comment, by one of the following three entities:
(1) The State Emergency Response Commission (SERC).
(2) The Governor of the State in which your facility is located.
(3) The Chief Executive Officer of the Tribe for the Indian Tribe under whose jurisdiction your facility is located.
The emergency planning requirements of this subpart apply to any EHS listed in Appendices A and B of this part. Additionally, if a facility is designated for emergency planning purposes, as provided in §355.10(b), substances that are not EHSs at this facility may become subject to the emergency planning requirements.
Any EHS present at your facility in an amount equal to or greater than its TPQ triggers the emergency planning requirements of this subpart. The TPQs are listed in Appendices A and B of this part in the column labeled “threshold planning quantity.”
If an EHS is present in a mixture in a particular container, determine the quantity (in pounds) of the EHS in that container by multiplying the concentration of the EHS (in weight percent) by the weight (in pounds) of the mixture in the container. If the concentration of an EHS is less than or equal to one percent in the mixture, you do not have to count that EHS. Here is an example calculation:
Example: You have 150 pounds of a mixture that contains 20 weight percent of a certain EHS. The quantity of EHS present in the mixture is:
EHS (in pounds)
= (weight percent of EHS) × (weight of mixture)
= (20 percent) × (150 pound mixture)
= (0.20) × (150)
EHS (in pounds)
= 30 pounds
You must aggregate (i.e., add together) the amounts of each EHS at your facility to determine if a TPQ is present. This means that, for a particular EHS, you must determine the total amount present at any one time at your facility by adding together the quantity of pure EHS and the quantity contained in all mixtures, regardless of location, number of containers, or method of storage. You do not have to count an EHS in a mixture if the concentration of that EHS is less than or equal to one percent.
EHSs that are in solid form are subject to one of two different TPQs (for example, TPQs may be listed as 500/10,000 pounds), both of which are listed in Appendices A and B of this part. Here is how to determine which of the two listed TPQs you must use for an EHS present at your facility in solid form:
(a) Use the lower TPQ from Appendices A and B of this part if the solid:
(1) Is in powdered form and has a particle size less than 100 microns;
(2) Is in solution;
(3) Is in molten form; or
(4) Meets the criteria for a National Fire Protection Association (NFPA) rating of 2, 3 or 4 for reactivity.
Note to paragraph (a): Use the instructions in §355.16 to calculate the quantity present for the categories of solids listed in paragraphs (a)(1), (2) and (3) of this section.
(b) If the solid does not meet one of the criteria in paragraph (a) of this section, then the TPQ is 10,000 pounds.
For the three forms of solids that are listed in §355.15(a)(1) through (3), use these instructions to determine the quantity of extremely hazardous substance present:
(a) Solid in powdered form with a particle size less than 100 microns. Multiply the weight percent of solid with a particle size less than 100 microns in a particular container by the total weight of solid in the container.
(b) Solid in solution. Multiply the weight percent of the non-reactive solid in solution in a particular container by the total weight of solution in that container. Then multiply by 0.2.
Note to paragraph (b): This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10.
(c) Solid in molten form. Multiply the weight of the non-reactive solid in molten form by 0.3.
Note to paragraph (c): This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10.

Use this table to determine the information you must provide, who to provide it to, and when:
|What types of emergency planning notification are required? ||What information must I provide? ||To whom must I provide the|
|When must I provide the information? |
|(a) Emergency planning notification||You must provide notice that your facility is subject to the emergency planning requirements of this subpart||To the SERC and the LEPC||Within 60 days after your facility first becomes subject to the requirements of this subpart. If no LEPC exists for your facility at the time you are required to provide emergency planning notification, then you should report to the LEPC within 30 days after an LEPC is established for the emergency planning district in which your facility is located. |
|(b) Facility emergency coordinator||You must designate a facility representative who will participate in the local emergency planning process as a facility emergency response coordinator. You must provide notice of this facility representative||To the LEPC (or the SERC if there is no LEPC, or the Governor if there is no SERC)||Within 60 days after your facility first becomes subject to the requirements of this subpart. If no LEPC exists when you first report, then provide an additional report to the LEPC within 30 days after such LEPC is established for the emergency planning district in which your facility is located. |
|(c) Changes relevant to emergency planning||You must provide notice of any changes occurring at your facility that may be relevant to emergency planning||To the LEPC||Within 30 days after the changes have occurred. |
|(d) Requested information||You must provide any information necessary for developing or implementing the local emergency plan if the LEPC requests it||To the LEPC||Promptly. Note: The LEPC may specify a time frame for this information.|
EPA does not require any specific format. EPA recommends that you submit the information described in §355.20 in writing in order to insure appropriate documentation. The SERC or LEPC may request that this information be submitted in a specific format.
You must comply with the emergency release notification requirements in this subpart if both of these two conditions are met:
(a) You produce, use, or store a hazardous chemical at your facility; and
(b) You release a reportable quantity (RQ) of any EHS or of a hazardous substance as defined by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA Hazardous Substance) at your facility. Certain releases are exempted from these requirements. Exempted releases are listed in §355.31.
Note to paragraph (b): In addition to the emergency release notification requirements of this subpart, releases of CERCLA hazardous substances are subject to the notification requirements under CERCLA. This is explained further in subpart D of this part.
You do not have to provide emergency release notification under this subpart for any of the following six types of releases of EHSs or CERCLA hazardous substances that occur at your facility:
(a) Any release that results in exposure to persons solely within the boundaries of your facility.
(b) Any release that is a federally permitted release as defined in section 101(10) of CERCLA.
(c) Any release of a pesticide product that is exempt from reporting under section 103(e) of CERCLA.
(d) Any release that does not meet the definition of release under section 101(22) of CERCLA and is therefore exempt from CERCLA section 103(a) reporting.
(e) Any radionuclide release that occurs:
(1) Naturally in soil from land holdings such as parks, golf courses, or other large tracts of land.
(2) Naturally from land disturbance activities, including farming, construction, and land disturbance incidental to extraction during mining activities, except that which occurs at uranium, phosphate, tin, zircon, hafnium, vanadium, monazite, and rare earth mines. Land disturbance incidental to extraction includes: Land clearing; overburden removal and stockpiling; excavating, handling, transporting, and storing ores and other raw (not beneficiated or processed) materials; and replacing in mined-out areas coal ash, earthen materials from farming or construction, or overburden or other raw materials generated from the exempted mining activities.
(3) From the dumping and transportation of coal and coal ash (including fly ash, bottom ash, and boiler slags), including the dumping and land spreading operations that occur during coal ash uses.
(4) From piles of coal and coal ash, including fly ash, bottom ash, and boiler slags.
(f) Any release less than 1,000 pounds per 24 hours of nitrogen oxide or nitrogen dioxide to the air which is the result of combustion and combustion related activities.
(g) Any release to the air of a hazardous substance from animal waste at farms that stable or confine fewer than the numbers of animal specified in any of the following categories.
(1) 700 mature dairy cows, whether milked or dry.
(2) 1,000 veal calves.
(3) 1,000 cattle other than mature dairy cows or veal calves. Cattle includes but is not limited to heifers, steers, bulls and cow/calf pairs.
(4) 2,500 swine each weighing 55 pounds or more.
(5) 10,000 swine each weighing less than 55 pounds.
(6) 500 horses.
(7) 10,000 sheep or lambs.
(8) 55,000 turkeys.
(9) 30,000 laying hens or broilers, if the farm uses a liquid manure handling system.
(10) 125,000 chickens (other than laying hens), if the farm uses other than liquid manure handling system.
(11) 82,000 laying hens, if the farm uses other than a liquid manure handling system.
(12) 30,000 ducks (if the farm uses other than a liquid manure handling system).
(13) 5,000 ducks (if the farm uses a liquid manure handling system).
(h) Any release to the air of a hazardous substance from animal waste at farms from animals that are not stabled or otherwise confined.
[73 FR 65462, Nov. 3, 2008, as amended at 73 FR 76960, Dec. 18, 2008]
If the release of an EHS or CERCLA hazardous substance is continuous and stable in quantity and rate at your facility as defined in 40 CFR 302.8(b), then the release qualifies for reduced reporting requirements under this subpart. Under these reduced reporting requirements, you do not need to provide the notifications required under §355.40. However, in addition to the notifications required under 40 CFR 302.8, you must make all of the following notifications to the community emergency coordinator for the LEPC for any area likely to be affected by the release and to the SERC of any State likely to be affected by the release:
(a) Initial notifications as specified in 40 CFR 302.8 (d) and (e).
(b) Notification of a “statistically significant increase,” defined in 40 CFR 302.8(b) as any increase above the upper bound of the reported normal range.
(c) Notification of a “new release” as specified in 40 CFR 302.8(g)(1).
(d) Notification of a change in the normal range of the release as specified under 40 CFR 302.8(g)(2).
The release of a reportable quantity (RQ) of an EHS or CERCLA hazardous substance within any 24-hour period triggers the emergency release notification requirements. RQs for EHSs are listed in Appendices A and B of this part in the column labeled “reportable quantity.” RQs for CERCLA hazardous substances are listed in Table 302.4 of 40 CFR 302.4 in the column labeled “final RQ.”
You must make two separate notifications to comply with the emergency release notification requirements of this subpart: an immediate notification, and as soon as practicable thereafter a written follow-up emergency notification (or notifications, as more information becomes available).
(a) Immediate notification. The notice required under this section shall include as much of the following information known at the time. However, the retrieval of this information should not cause a delay in the notification on the emergency response.
(1) The chemical name or identity of any substance involved in the release.
(2) Indicate whether the substance is an EHS.
(3) Provide an estimate of the quantity of any such substance that was released into the environment.
(4) State the time and duration of the release.
(5) The medium or media into which the release occurred.
(6) Any known or anticipated acute or chronic health risks associated with the emergency and, where appropriate, advice regarding medical attention necessary for exposed individuals.
(7) Proper precautions to take as a result of the release, including evacuation (unless such information is readily available to the community emergency coordinator pursuant to the emergency plan).
(8) The name and telephone number of the individual (or individuals) to be contacted for further information.
(b) Written follow-up emergency notification. Except for releases that occur during transportation or from storage incident to transportation, you must provide a written follow-up emergency notice (or notices, as more information becomes available), as soon as practicable after the release. In the written follow-up emergency notice, you must provide and update the information required in the immediate notification and include additional information with respect to all of the following:
(1) Actions taken to respond and contain the release.
(2) Any known or anticipated acute or chronic health risks associated with the release.
(3) Where appropriate, advice regarding medical attention necessary for exposed individuals.
(c) You are not required to submit a written follow-up notification for a release that occurred during transportation or from storage incident to transportation. See §355.42(b) for requirements for reporting such releases.
The immediate notification, described in §355.40(a), should be oral. The follow-up emergency notification, described in §355.40(b), shall be in writing. EPA does not specify a particular format for the written follow-up emergency notification.
Note: The LEPC may request a specific format for this information.
(a) You must provide the immediate emergency release notification information and the written follow-up notification to:
(1) The community emergency coordinator for the LEPC of any area likely to be affected by the release (if there is no LEPC, notify the relevant local emergency response personnel); and
(2) The SERC of any State likely to be affected by the release.
(b) For a release that occurs during transportation or from storage incident to transportation, you may meet the requirements of this 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 §355.40(a). You are not required under this subpart to submit a written follow-up notification, as described in §355.40(b), for such a release.
(a) You must provide the required emergency release notification information described under §355.40(a), immediately.
(b) You must provide the written follow-up emergency notice (or notices, as more information becomes available) described under §355.40(b), as soon as practicable after the release.
The emergency release notification requirements of this part are in addition to the release notification requirements of CERCLA. If you have a release of a CERCLA hazardous substance, you must comply with the emergency release notification requirements of this part and the release notification requirements of CERCLA section 103, codified at 40 CFR part 302. Use this table to determine which emergency release notification requirements apply to your release:
|If a reportable quantity of a substance is released within a 24-hour period at your facility ||And if the release is reportable under EPCRA Section 304, you must ||And if the release is reportable under CERCLA Section 103, you must |
|(a) And the substance is on BOTH the list of EHSs (Appendices A and B of this part) AND the list of CERCLA Hazardous Substances (40 CFR 302.4)||Notify the LEPC and the SERC in accordance with §§355.40 through 355.43 of this part (except for a release during transportation or from storage incident to transportation; see §355.42(b))||Comply with the release notification requirements of CERCLA section 103 and its implementing regulations (40 CFR part 302). Call the NRC at 800-424-8802. |
|(b) And the substance is on the list of CERCLA Hazardous Substances (40 CFR 302.4) and not on the list of EHSs (Appendices A and B of this part)||Notify the LEPC and the SERC, in accordance with §§355.40 through 355.43 of this part (except for a release during transportation or from storage incident to transportation; see in §355.42(b))||Comply with the release notification requirements of CERCLA section 103 and its implementing regulations (40 CFR part 302). Call the NRC at 800-424-8802. |
