Attachment I Page 1 of 2 RAI #1 Minimum DFA calculation:
Various regional inflation factors were not available in final form for December 2010 during the drafting of our Decommissioning Funding Status (DFS) dated April 11, 2011.
The escalation factors originally submitted have been adjusted as set forth in Exhibit #1 as attached herein. The revised factors resulted in a 1 percent increase to the current estimated minimum decommissioning requirements, however, the overall strategy, expected future contributions and results of trust earnings did not change significantly from the original DFS filing. After applying Allegheny's assumptions as originally submitted to the revised minimum decommissioning requirements on Exhibit #1, Allegheny's plan achieves adequate funding for the decommissioning cost many years prior to end of the license lives for Unit #1 and Unit #2 of 2042 and 2044 respectively.
RAI #2 Citation for real rate of returns:
Allegheny Electric Cooperative, Inc. is incorporated in the Commonwealth of Pennsylvania as a Non-Profit Electric Cooperative Corporation. As such, Allegheny is excluded from regulation under the Pennsylvania Public Utility Commission.
Allegheny's Board of Directors has full and exclusive authority to establish wholesale rates that are binding to its customers. Allegheny has "All-Requirements Contracts" with each of its 14 rural electric distribution cooperative customers. Additionally, Allegheny's total energy sales approximate 3,263,000 MWh and therefore Allegheny is not subject to regulation under the Federal Energy Regulatory Commission (FERC).
The rates of escalation in the April 11, 2011 filing were determined by Allegheny's management based on a strategy and series of policies previously approved by the Allegheny Board of Directors. The estimated inflation rate for decommissioning costs in the 2011 DFS filing are based on a historical comparison of site-specific studies that were completed by PPL Susquehanna, LLC as the majority owner and exclusive operator of the Susquehanna Steam Electric Station Units #1 and #2. The site specific study completed in 2002 was compared to the site specific study completed in 2010.
The annualized rate of inflation approximated 4 percent. Based on numerous observations related to recent trends in energy as well as indications that waste burial costs may have significant upward pressure, management determined that an inflation rate of 5 percent was more appropriate looking forward.
The estimated rate of earnings on decommissioning funds as submitted was 6.5 percent. The after-tax rate of return on Allegheny's trust fund since the trust's inception in 1990 is approximately 7.5 percent. While such earnings may be achievable in the future, Allegheny's management believes that the turmoil in the financial markets that began during 2007 may continue into the future. With the existing target allocation of trust fund investments at 50 percent equity and 50 percent fixed income, Allegheny believes that it has a well diversified portfolio. The historical return of 7.5 percent was decreased to 6.5 percent due to an extended period of low returns and slow domestic
Attachment #1 Page 2 of 2 growth. As such, the real rate of return after inflation of 5 percent and income tax is 1.5 percent, and considerably more conservative than the allowed 2 percent provided for in the regulations.
There were no other rates or factors used in the funding projections as submitted in the Decommissioning Funding Status report as submitted on April 11, 2011.
RAI #3 After-tax decommissioning funds as of December 31, 2010:
The amount of funds reported in the DFS submitted on April 11, 2011 are after-tax amounts accumulated through December 31, 2010.

Exhibit #1 Page 1 of 2 Revised Calculation of Escalation Factors Used in Computation of Minimum Financial Assurance Amount for Decommissioning Susquehanna Steam Electric Station Units 1 and 2 June 15, 2011 Boiling Water Reactor (BWR)
Escalation Factor Formula - 0.65(L) + 0.13(E) + 0.22(B)
Escalation = (0.65 x 2.454) + (0.13 x 2.3 19) + (0.22 x 12.540)
Escalation = (1.595 + 0.301 + 2.759) = 4.655 (L) - Labor NUREG - 1307, Rev. 14, Table 3.2 Regional Factors for Labor Cost Adjustment -
To calculate the current labor adjustment factor (Lx) for a particular region, two numbers are needed: a base labor adjustment factor and the current Employment Cost Index (ECI). The base labor adjustment factors are shown in column 2 of Table 3.2, and the current employment cost indexes are shown in column 3. For the Northeast region, Lx/113.6 = 2.16/100 or Lx = 2.16*113.6/100 = 2.454 (E) - Energy Adjustment Factor NUREG - 1307, Rev. 14, Section 3.2 Energy Adjustment Factors - The adjustment factor for energy, Ex, is a weighted average of two components, namely, industrial electric power, Px, and light fuel oil, Fx. For the reference BWR it is: Ex (BWR) =
0.54Px + 0.46Fx. Updating the components from the provided references results in for the reference BWR:
Ex (BWR) = [(0.54 x 1.675) + (0.46 x 3.074)] = 2.319 (B) - Waste Burial NUREG - 1307, Rev.14, Table 2.1 - Values of Bx as a Function of LLW Burial Site, Waste Vendor, and Year: Bx Values for Generic LLW Disposal Site Direct Disposal with Vendors (BWR): 12.540

Provide the minimum decommissioning funding assurance calculation by using current escalation factors for labor and energy from the U.S. Department of Labor, Bureau of Labor Statistics and, if necessary, a corrected submittal for that part of the DFS Report.
On March 29, 2011, AEC reported an amount of decommissioning funds estimated to be required under 10 CFR 50.75(b) and (c) less than the amount calculated by the NRC staff. Also, AEC used the factors for labor and energy taken from NUREG-1307, Rev. 14, "Report on Waste Burial Charges: Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities."
According to 10 CFR 50.75(f)(1), the amount provided in the DFS report should be "the amount of decommissioning funds estimated to be required under 10 CFR 50.75(b) and (c)."
As stated under 10 CFR 50.75(c)(2):
[e]scalation factors for labor and energy ... are to be taken from regional data of U.S. Department of Labor Bureau of Labor Statistics...
RAI #2: Citation for real rate of returns:
Provide the citation (e.g., an Order by the rate-regulatory authority) by the regulatory entity that allows for the assumptions used regarding rates of escalation in decommissioning costs, rate of earnings on decommissioning funds and rates of other factors assumed within the DFS Report.
Enclosure
In the submission on March 29, 2011, AEC reported the following:
5 percent rate of escalation in decommissioning costs, 6.5 percent rates of earnings on decommissioning funds As stated in 10 CFR 50.75(f)(1),
...The information in [the DFS] report must include [...] the assumptions used regarding rates of escalation in decommissioning costs, rates of earnings on decommissioning funds, and rates of other factors used in funding projections...
RAI #3: After-tax decommissioning funds as of December 31, 2010:
Indicate if the amount of decommissioning funds identified within the DFS Report for SSES 1 and 2 are the after-tax amounts of decommissioning funds accumulated through December 31, 2010. If not, provide the after-tax amounts of decommissioning funds accumulated through December 31, 2010.
In the submission on March 29, 2011, AEC reported the amounts of decommissioning funds accumulated as of December 31, 2010, for SSES 1 and 2, but did not indicate if the amounts stated were the before or after-tax balances.
The provisions of 10 CFR 50.75(f)(1) and (2) require the licensee to report the amount of funds accumulated to the end of the calendar year preceding the report.
