# Subpart A—General Information

§ 355.1 What is the purpose of this part?
(a) This part (40 CFR part 355) establishes requirements for a facility toprovide 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


# 429 Environmental Protection Agency § 355.13

Substances (EHSs) and Threshold Planning Quantities (TPQs) in Appendices A and B, which are used in determiningif you are subject to these requirements.

(b) This part is written in a special format to make it easier to understand the regulatory requirements. Likeother 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’’ anda smaller typeface. Such notes are provided for information purposes only and are not considered legally binding under this part.

§ 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.

§ 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.



# Subpart B—Emergency Planning

W HO 

## M UST 

## C OMPLY



## § 355.10 Must my facility comply withthe 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, afterpublic 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.

§ 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 thispart. 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.

§ 355.12 What quantities of extremelyhazardous 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.’’

§ 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 thatcontainer by multiplying the concentration of the EHS (in weight percent) by the weight (in pounds) of themixture 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


# 430 40 CFR Ch. I (7–1–13 Edition) § 355.14

§ 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 ispresent. 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 tocount an EHS in a mixture if the concentration of that EHS is less than or equal to one percent.

§ 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.

N OTE 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 ofthe criteria in paragraph (a) of this section, then the TPQ is 10,000 pounds. § 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 thequantity of extremely hazardous substance present:

(a) Solid in powdered form with a particle size less than 100 microns. Multiplythe 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-reactivesolid in solution in a particular container by the total weight of solution in that container. Then multiply by 0.2.

N OTE 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 theweight of the non-reactive solid in molten form by 0.3.

N OTE 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.

* Only the 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 volu me 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 thewrong 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.

* Only the 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 volu me 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 thewrong 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.
