CONSOLIDATED CHECKLIST C5
	Part 3 of 5 parts

	Standards for Owners and Operators of Hazardous Waste Treatment,
	Storage, and Disposal Facilities
	40 CFR Part 264, Subparts K-S, as of December 31, 2002
	
Note: No final rules affecting 40 CFR Part 264, Subparts K-S were promulgated between June 30, 2002 and December 31, 2002, therefore, this Consolidated Checklist corresponds to 40 CFR Part 264, Subparts K-S as published on July 1, 2002.

Note: Consolidated Checklist C5 is divided into five separate documents/computer files solely for ease of handling its printed and electronic versions.  Consolidated Checklist C5 remains one checklist; States must adopt all five portions simultaneously to correctly use this Consolidated Checklist.  Note, the prenotes and endnotes associated with each part have been placed with the part to which they apply.
