*Only the statutory or final reportable quantity (RQ) is shown. For more information, see 40 CFR, Table 302.4. Notes:
  1. This chemical does not meet acute toxicity criteria. Its threshold planning quantity (TPQ) is set at 10,000 pounds.
  2. This material is a reactive solid. The TPQ does not default to 10,000 pounds for nonpowder, nonmolten, nonsolution form.
  3. The calculated TPQ changed after technical review, as described in the technical support document.
  4. The RQ is subject to change when the assessment of potential carcinogenicity and/or other toxicity is completed.
  5. Statutory reportable quantity for purposes of notification under Superfund Amendments and Reauthorization Act (SARA) section 304(a)(2).
  6. [Reserved]
  7. New chemicals added that were not part of the original list of 402 substances.
  8. Revised TPQ based on new or re-evaluated toxicity data.
  9. TPQ is revised to its calculated value and does not change because of technical review, as in proposed rule.
  10. The TPQ was revised after proposal because of calculation error.
  11. Chemicals on the original list that do not meet toxicity criteria but, because of their high production volume and recognized toxicity, are considered chemicals of concern ("other chemicals").
