EXPLANATORY NOTE



We are filing this Amendment No. 1 on Form 10-K/A solely to correct a typographical error made by our printer/filing agent in the process of converting and formatting the
Annual Report on Form 10-K to an electronic format suitable for filing with the Securities Exchange Commission (SEC). The typographical error appeared in the Report of Independent Registered Public Accounting Firm contained in Item 15. Exhibits
and Financial Statement Schedules of our original Annual Report on Form 10-K filed on March 2, 2006 (Original Report). Specifically, the signature of our independent registered public accounting firm was unintentionally omitted and the
date of the report was incorrectly stated as March 1, 2006. The report has been revised to include the signature of our independent registered public accounting firm and the date of the report has been corrected to March 2, 2006.



In order to comply with certain technical requirements of the SECs rules in
connection with the filing of this amendment on Form 10-K/A; we are also including in this amendment updated certifications of our principal executive and principal financial officers and an updated Consent of Independent Registered Public
Accounting Firm.



This Amendment No. 1 to our Report on Form 10-K as
originally filed on March 2, 2006 continues to speak as of the date of our Original Report, and we have not updated the disclosures contained in this Amendment No. 1 to reflect any events that occurred at a date subsequent to the filing of
the Original Report.

Report of Independent Registered Public Accounting Firm



To the Shareholder and Board of Directors of

Consolidated Natural
Gas Company



We have audited the consolidated financial statements of Consolidated
Natural Gas Company (a wholly-owned subsidiary of Dominion Resources, Inc.) and subsidiaries (the Company) as of December 31, 2005 and 2004, and for each of the three years in the period ended December 31, 2005, and have issued our
report thereon dated March 2, 2006 (which report expressed an unqualified opinion and included an explanatory paragraph as to changes in accounting principles for: conditional asset retirement obligations in 2005 and asset retirement obligations,
derivative contracts not held for trading purposes, and the consolidation of variable interest entities in 2003); such report has previously been filed as part of the Companys Annual Report on Form 10-K for the year ended December 31, 2005.
Our audits also included the financial statement schedule of the Company listed in the accompanying index at Item 15. This financial statement schedule is the responsibility of the Companys management. Our responsibility is to express an
opinion based on our audits. In our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth
therein.

Indemnifications

As part of commercial contract negotiations in the normal course of business, we may sometimes agree to make payments to compensate or indemnify other parties for possible future unfavorable financial consequences resulting from specified
events. The specified events may involve an adverse judgment in a lawsuit or the imposition of additional taxes due to a change in tax law or interpretation of the tax law. We are unable to develop an estimate of the maximum potential amount of
future payments under these contracts because events that would obligate us have not yet occurred or, if any such event has occurred, we have not been notified of its occurrence. However, as of December 31, 2005, we believe future payments, if any,
that could ultimately become payable under these contract provisions, would not have a material impact on our results of operations, cash flows or financial position.



Note 4. Dividend Restrictions

We received dividends from
our consolidated subsidiaries in the amounts of $575 million, $481 million and $405 million in 2005, 2004 and 2003, respectively.

The Public Utility
Holding Company Act of 1935 (1935 Act) and related regulations issued by the SEC impose restrictions on the transfer and receipt of funds by a registered holding company from its subsidiaries, including a general prohibition against loans or
advances being made by the subsidiaries to benefit the registered holding company. Under the 1935 Act, registered holding companies and their subsidiaries may pay dividends only from retained earnings, unless the SEC specifically authorizes payments
from other capital accounts. In response to a Dominion request, the SEC granted relief in 2000, authorizing payment of dividends by us from other capital accounts to Dominion in amounts of up to $1.6 billion, representing our retained earnings prior
to Dominions acquisition of us. The SEC granted further relief in 2004, authorizing our nonutility subsidiaries to pay dividends out of capital or unearned surplus in situations where such subsidiary has received excess cash from an asset
sale, engaged in a restructuring, or is returning capital to an associate company. We are not bound by the foregoing restrictions on dividends imposed by the 1935 Act as of February 8, 2006, the effective date on which such Act was repealed under
the Energy Policy Act of 2005.
