RCRA REVISION CHECKLIST 74 Toxicity Characteristic Revisions 55 FR 11798-11877

March 29, 1990 as amended on June 29, 1990, at 55 FR 26986-26998 (RCRA Cluster II)
Note: 1) Acorrection to the preamble of the March 29, 1990 rule was published on August 2, 1990 (55 FR3138.7). This notice corrected an implementation timetable and extended the period of time withinwhich affected small quantity generators must comply with the newmodification requirements. AnAugust 10, 1990 (55 

### EB 32733) notice corrected the August 2, 1990 notice.. OnSeptember 27, 1990, a clarification to the March 29 final rule was published in the Federal Register (55 FR39409) regarding four implementation issues. The clarification didnot affect the Federal code addressedby this checklist. Aninterim final rule promulgated on October 5, 1990 (55 FR40834) did affect the Federal code relevant to the Toxicity Characteristic. Aseparate revision checklist (Revision Checklist 80) was developed to address those changes effectedby the interim final rule. 2) Two interim final rules (55 FR40834; October 5, 1990 and 56 FR3978; February 1, 1991) and a final rule (56 FR13406; April 2, 1991) extended the compliance date of the Toxicity Characteristic (TC) rule for certainhydrocarbon recovery and remediation operations. This extension is addressedby Revision Checklist 80

.. Because a less stringent requirement than that imposedby the TC rule is in effect until January 23, 1993, that Revision Checklist is optional.

. 3) States are strongly encouraged to adopt the Permit Modifications rule (53 FR 37912; September 28, 1988; Revision Checklist 54) and the "Christmas Tree Rule" (54 FR9596; March 7, 1989; Revision Checklist 61) to ease implementation ofthe Toxicity Characteristic Rule and future waste listings. While both ofthese rules are optional, they will greatly reduce the immediate permitburden resulting from the TC rule.

PART 268 - LAND DISPOSALRESTRICTIONS
APPENDIX I TO PART 268

March 29, 1990

. Page 4 of4 2 Because the June 29, 1990 (55 FR 26986) notice made extensive corrections to Appendix II, Part 261, the Appendix in thatnotice shouldbe used instead ofthe one in the March 29, 1990 (55 FR 11798) notice. 3 Asbackground, the TCLP was originally promulgated in 268, Appendix I, on November 7, 1986 (51 FR40572; Revision Checklist 34) for use in the Land Disposal Restrictions (LOR) program to determine whether certainwastes require treatment prior to land disposal and to determine whether certain treatedwastes meet the applicable treatment standards. The TC rule and its June 29, 1990 modification promulgated a revised TCLP at 261, Appendix II, with modifications based on the Agency's ownresearch andpublic comment. This TCLP is to be used inboth the TC and the LORprograms. The objective ofthe above footnoted revision to 268, Appendix I, is to assure that the TCLP entered into the code by the November 7, 1986 notice (51 FR40572; Revision Checklist 34) is removed and replacedby the TCLP entered into the code and amendedby the final rules (55 FR 11798 and 55 FR 26986) addressedby Revision Checklist 74. The actual placement ofthe TCLP within a State's code is not that important, per se; what is important is that a State's code contains only the Revision Checklist 74 TCLP. States thathave not yet adopted Revision Checklist 34 (the first ofthe LOR restrictions) neednot make this particular revision to 268, Appendix I, as they would not yethave entered the original Part 268 TCLP into their code. Also, the change onpage 2 of this checklist for 261, Appendix II, assures that they add the Revision Checklist 74 TCLP to their code. However, such States mustbe careful when adding the LOR restrictions to their code, i.e., the Revision Checklist 34 TCLP should not be added at that time--rather, the Revision Checklist 74 TCLP should remain the only TCLP in their code. States using the Consolidated LOR Checklist shouldbe sure to read Footnote 40 on that checklist regarding this issue
