Item 4. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

Andersen, Andersen & Strong, L.C., Certified Public Accountants located in Salt Lake City, Utah audited the financial statements of Rocky Mountain Energy Corporation (formerly known as Emission Control Devices, Inc.) for the years ended December 31, 2001 and 2000. Andersen, Andersen & Strong, was dismissed by management on August 1, 2002, as a result of engaging another auditor for the Company, Massella Rubenstein, LLP on August 1, 2002.

The decision to change accountants was approved by the board of directors.

There were no disagreements between the Company and Andersen, Andersen & Strong, L.C. whether resolved or not resolved, on any matter of accounting principles or practices, financial statement disclosure or auditing, scope or procedure which, if not resolved, would have caused them to make reference to the subject matter of the disagreement in connection with their reports.

The Reports of Andersen, Andersen & Strong, P.C. for the years of 2001 and 2000, did not contain any adverse opinions or disclaimers of opinion, but noted as to uncertainty, audit scope or accounting principles as follows:

Note 4 of the audited financial statements of Emission Control Devices, Inc. for the year ended December 31, 2001, addressed "Going Concern" uncertainties, which stated, in part, "Continuation of the Company as a going concern is dependent on obtaining additional working capital and the management of the Company has developed a strategy, which it believes will accomplish this objective through additional equity funding and long term financing which will enable the company to operate for the coming year." Management does not disagree with this statement.

Management did not consult Massella Rubenstein, LLP regarding the application of accounting principles to a specific completed or contemplated transaction or the type of audit opinion that might be rendered, nor concerning any matter that was the subject of any disagreement or event.
