Item 2.02.  Results of Operations and Financial Condition.

See Item 4.02(a).

This information, including exhibits attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section.  This information shall not be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference to this Form 8-K in such a filing.

Item 4.02(a).  Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

On October 30, 2007, MarkWest Hydrocarbon (the “Company”) and its Audit Committee, determined that previously issued consolidated financial statements for the years ended December 31, 2006 and 2005, including the quarters therein, and the quarters ended March 31 and June 30, 2007 should be restated to correct an error in accounting for certain revenue arrangements in the East Texas business segment of MarkWest Energy Partners, a wholly-owned subsidiary of the Company.  Accordingly, the Audit Committee of the Company concluded that the consolidated financial statements for such periods should not be relied upon.  The restatement involves transactions in which the Company has determined it acted as a principal instead of an agent, thereby giving rise to accounting for revenue from such activities on a gross rather than net basis.  The Company arrived at this decision after an extensive review of its accounting for revenue arrangements consistent with the guidance in Emerging Issues Task Force (“EITF”) Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent.

The restatements will be reflected in a Form 10-K/A for the year ended December 31, 2006 and Form 10-Q/As for the two interim quarters during 2007, which the Company intends to file shortly after the filing of this report.

While this misstatement of revenue and expenses within the consolidated statements of operations does not affect net income, earnings per unit, distributable cash flow, the consolidated statements of stockholders’ equity or consolidated balance sheets, the Audit Committee of the board of directors and management determined that the misstatement required a restatement of the consolidated statements of operations.  This reclassification has the effect of increasing the amounts included in the revenue line item “Unaffiliated parties” and increasing, by the same amount, the amounts included in “Purchased product costs”.

The Company’s management and the Audit Committee have discussed with Deloitte & Touche LLP, who serves as the Company’s current independent registered public accounting firm, the matters disclosed in this Form 8-K.
