FOR FURTHER INFORMATION: Contact the employee listed in the ADDRESSES section of this notice. SUPPLEMENTARY INFORMATION: I. Background When rock bursts occur in an underground mine, they pose a serious threat to the safety of miners in the area affected by the burst. These bursts may reasonably be expected to result in the entrapment, serious physical harm, or death, of miners. Recently developed mining technology now permits mine operators to monitor rock stresses, which helps predict an impending burst. These predictions can be used by a mine operator to move miners to safer locations and to establish areas that need relief drilling. Title 30, Section 57.3461 requires operators of underground metal and nonmetal mines to develop a rock burst control plan within 90 days after a rock burst has occurred. sroberts on PROD1PC70 with NOTICES II. Desired Focus of Comments Currently, the Mine Safety and Health Administration (MSHA) is soliciting comments concerning the proposed extension of the information collection requirement related to the Rock Burst Control Plans. MSHA is particularly interested in comments that: • Evaluate whether the proposed collection of information is necessary for the proper performance of MSHA’s functions, including whether the information has practical utility; • Evaluate the accuracy of MSHA’s estimate of the burden of the proposed collection of information, including the VerDate Aug<31>2005 21:55 Oct 12, 2007 Jkt 214001 validity of the methodology and assumptions used; • Suggest methods to enhance the quality, utility, and clarity of the information to be collected; and • Address the use of appropriate automated, electronic, mechanical, or other technological collection techniques or other forms of information technology, (e.g., permitting electronic submissions of responses) to minimize the burden of the collection of information on those who are to respond. A copy of the proposed information collection request can be obtained by contacting the employee listed in the ADDRESSES section of this notice or viewed on the internet by accessing the MSHA home page (http:// www.msha.gov/) and selecting ‘‘Rules and Regs’’, then selecting ‘‘Fed Reg Docs.’’ III. Current Actions This information collection needs to be extended to protect miners from entrapment, serious physical harm or death, in metal and nonmetal underground mines with a history of rock bursts.

Interest rates are also published on the PBGC’s Web site (http://www.pbgc.gov). DATES: The required interest rate for determining the variable-rate premium under part 4006 applies to premium payment years beginning in October 2007. The interest assumptions for performing multiemployer plan valuations following mass withdrawal under part 4281 apply to valuation dates occurring in November 2007. The interest rates for late premium payments under part 4007 and for underpayments and overpayments of single-employer plan termination liability under part 4062 and multiemployer withdrawal liability under part 4219 apply to interest accruing during the fourth PO 00000 Frm 00057 Fmt 4703 Sfmt 4703 58339 quarter (October through December) of 2007.

Klion, Manager, Regulatory and Policy Division, Legislative and Regulatory Department, Pension Benefit Guaranty Corporation, 1200 K Street, NW., Washington, DC 20005, 202–326– 4024. (TTY/TDD users may call the Federal relay service toll-free at 1–800– 877–8339 and ask to be connected to 202–326–4024.) SUPPLEMENTARY INFORMATION: Variable-Rate Premiums Section 4006(a)(3)(E)(iii)(II) of the Employee Retirement Income Security Act of 1974 (ERISA) and § 4006.4(b)(1) of the PBGC’s regulation on Premium Rates (29 CFR part 4006) prescribe use of an assumed interest rate (the ‘‘required interest rate’’) in determining a single-employer plan’s variable-rate premium. Pursuant to the Pension Protection Act of 2006, for premium payment years beginning in 2006 or 2007, the required interest rate is the ‘‘applicable percentage’’ of the annual rate of interest determined by the Secretary of the Treasury on amounts invested conservatively in long-term investment grade corporate bonds for the month preceding the beginning of the plan year for which premiums are being paid (the ‘‘premium payment year’’). On February 2, 2007 (at 72 FR 4955), the Internal Revenue Service (IRS) published final regulations containing updated mortality tables for determining current liability under section 412(l)(7) of the Code and section 302(d)(7) of ERISA for plan years beginning on or after January 1, 2007. As a result, in accordance with section 4006(a)(3)(E)(iii)(II) of ERISA, the ‘‘applicable percentage’’ to be used in determining the required interest rate for plan years beginning in 2007 is 100 percent. The required interest rate to be used in determining variable-rate premiums for premium payment years beginning in October 2007 is 6.23 percent (i.e., 100 percent of the 6.23 percent composite corporate bond rate for September 2007 as determined by the Treasury). The following table lists the required interest rates to be used in determining variable-rate premiums for premium payment years beginning between November 2006 and October 2007.
