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.

* Only the statutory or final RQ is shown. For more information,
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.
