PART 355—EMERGENCY PLANNING AND NOTIFICATION ContentsSubpart A—General Information
Authority: Sections 302, 303, 304, 325, 327, 328, and 329 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) (42 U.S.C. 11002, 11003, 11004, 11045, 11047, 11048, and 11049). Source: 73 FR 65462, Nov. 3, 2008, unless otherwise noted. Back to Top
§355.1 What is the purpose of this part?(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. Back to Top
§355.2 Who do “you,” “I,” and “your” refer to in this part?Throughout this part, “you,” “I,” and “your” refer to the owner or operator of a facility. Back to Top
§355.3 Which section contains the definitions of the key words used in this part?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. Back to Top
§355.10 Must my facility comply with the emergency planning requirements of this subpart?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. Back to Top
§355.11 To what substances do the emergency planning requirements of this subpart apply?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. Back to Top
§355.12 What quantities of extremely hazardous substances trigger 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.” Back to Top
§355.13 How do I calculate the quantity of an extremely hazardous substance present in mixtures?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
§355.14 Do I have to aggregate extremely hazardous substances to determine the total quantity present?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. Back to Top
§355.15 Which threshold planning quantity do I use for an extremely hazardous substance present at my facility in solid form?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. Back to Top
§355.16 How do I determine the quantity of extremely hazardous substances present for certain forms of solids?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.
§355.20 If this subpart applies to my facility, what information must I provide, who must I submit it to, and when is it due?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 theinformation? When must I provide the information? (a) Emergency planning notificationYou must provide notice that your facility is subject to the emergency planning requirements of this subpartTo the SERC and the LEPCWithin 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 coordinatorYou 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 representativeTo 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 planningYou must provide notice of any changes occurring at your facility that may be relevant to emergency planningTo the LEPCWithin 30 days after the changes have occurred. (d) Requested informationYou must provide any information necessary for developing or implementing the local emergency plan if the LEPC requests itTo the LEPCPromptly. Note: The LEPC may specify a time frame for this information. Back to Top
§355.21 In what format should the information be submitted?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. Back to Top
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. Back to Top
§355.31 What types of releases are exempt from the emergency release notification requirements of this subpart?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.

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.
§355.32 Which emergency release notification requirements apply to continuous releases?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). Back to Top
§355.33 What release quantities of EHSs and CERCLA hazardous substances trigger the emergency release notification requirements of this subpart?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.” Back to Top

statutory or final RQ is shown. For more information, see 40 CFR 355.61.Notes:a. This material is a reactive solid. The TPQ does not default to 10,000 pounds for non-powder, non-molten, non-solution form.b. The calculated TPQ changed after technical review as described in a technical support document for the final rule, April 22, 1987.c. Chemicals added by final rule, April 22, 1987.d. Revised TPQ based on new or re-evaluated toxicity data, April 22, 1987.e. The TPQ was revised due to calculation error, April 22, 1987.f. Chemicals on the original list that do not meet toxicity criteria but because of their acute lethality, high production volume and known risk are considered chemicals of concern (“Other chemicals”), November 17, 1986 and February 15, 1990.g. The TPQ was recalculated (September 8, 2003) since it was mistakenly calculated in the April 22, 1987 final rule under the wrong assumption that this chemical is a reactive solid, when in fact it is a liquid. RQ for this chemical was adjusted on September 11, 2006. Back to Top

Revised TPQ based on new or re-evaluated toxicity data, April 22, 1987.e. The TPQ was revised due to calculation error, April 22, 1987.f. Chemicals on the original list that do not meet toxicity criteria but because of their acute lethality, high production volume and known risk are considered chemicals of concern (“Other chemicals”). (November 17, 1986, and February 15, 1990.)g. The TPQ was recalculated (September 8, 2003) since it was mistakenly calculated in the April 22, 1987, final rule under the wrong assumption that this chemical is a reactive solid, when in fact it is a liquid. RQ for this chemical was adjusted on September 11, 2006. Back to Top
