The regulatory text of the June 20, 1996, Risk Management Program Rule (61 FR 31668) does not include Subpart F.  What is the content of Subpart F and when was it promulgated?

Subpart F of 40 CFR Part 68 consists of the regulations concerning the list of regulated substances, threshold quantities, and threshold determination that were originally promulgated in the List Rule (59 FR 4478; January 31, 1994) as Subpart C.  The June 20, 1996, rule redesignated the original Subpart C as Subpart F, amended Subpart A and added Subparts B, C, D, E, G, H, and Appendix A (61 FR 31717; June 20, 1996).  In Subpart F the original section numbers of the former Subpart C (§§68.100-68.130) remained unchanged.
