Rule 3750-25-10 | Determination of reportable quantities for hazardous substances.
[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (YY) of rule 3750-1-01 of the Administrative Code titled "Referenced materials."]
(A) Listed hazardous substances.
The quantity listed in the column entitled "Final RQ" for each substance in 40 CFR Part 302 Table 302.4, or in Appendix B to Table 302.4 is the reportable quantity (RQ) for that substance. The table and appendix has been incorporated by reference under paragraph (A) of rule 3750-20-50 of the Administrative Code. The RQs in 40 CFR Part 302 Table 302.4 are in units of pounds based on chemical toxicity, while the RQs in 40 CFR Part 302 Appendix B to Table 302.4 are in units of curies based on radiation hazard. Whenever the RQs in 40 CFR Part 302 Table 302.4 and Appendix B to the table are in conflict, the lowest RQ shall apply.
(B) Unlisted hazardous substances.
Unlisted hazardous substances designated by 40 CFR Part 302 Table 302.4 have the reportable quantity of one hundred pounds, except for those unlisted hazardous wastes which exhibit extraction procedure "Toxic Characteristic Leaching Procedure" (TCLP) toxicity identified in 40 CFR Part 261.24. Unlisted hazardous wastes which exhibit TCLP toxicity have the reportable quantities listed in 40 CFR Part 302 Table 302.4 for the contaminant on which the characteristic of TCLP toxicity is based. The reportable quantity applies to the waste itself, not merely to the toxic contaminant. If an unlisted hazardous waste exhibits TCLP toxicity on the basis of more than one contaminant, the reportable quantity for that waste shall be the lowest of the reportable quantities listed in 40 CFR Part 302 Table 302.4 for those contaminants. If an unlisted hazardous waste exhibits the characteristic of TCLP toxicity and one or more of the other characteristics referenced in 40 CFR Part 302 Table 302.4, the reportable quantity for that waste shall be the lowest of the applicable reportable quantities.
