Notes

  1. This chemical does not meet acute toxicity criteria. Its 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. This is a statutory reportable quantity for purposes of notification under SARA Section 304(a)(2).
  6. [Reserved]
  7. This is a new chemical added that was not part of the original list of 402 substances.
  8. The chemical has a revised TPQ based on new or reevaluated toxicity data.
  9. The TPQ is revised to its calculated value and does not change due to technical review as in proposed rule.
  10. The TPQ was revised after proposal due to calculation error.
  11. The chemical was on the original list and does not meet toxicity criteria but because of its high production volume and recognized toxicity, it is considered a chemical of concern.
