Notes:
Only the statutory or final RQ is shown. For more information, see 40CFR Table 302.4
This material is a reactive solid. The TPQ does not default to 10,000 pounds
for non-powder, non-molten, non-solution form.
The calculated TPQ changed after technical review as described in the technical support document.
Indicates that the RQ is subject to change when the assessment of potential
carcinogenic!"ty and/or other toxicity is completed.
Statutory reportable quantity for purposes of notification under SARA sect 304(a)<2).
The statutory 1 pound reportable quantity for methyl isocyanate may be adjusted in a future rulemaking ac
Mew chemicals added that were not part of the original list of 402 substances.
.Revised TPQ based on new or re-evaluated toxicity data.
TPQ is revised to its calculated value and does not change due to technical review as in proposed rule.
The TPQ was revised after proposal due to calculation error.
Chemicals on the original list that do not meet the toxicity criteria but because of their high productio
and recognized toxicity are considered chemicals of concern ("Other chemicals")
