Item 5.  Other Events.

         On September 6, 2001, certain members of Arch Coal, Inc.'s management
will make a presentation to members of the business and investment community.
The text of slides to be shown during the presentation is attached hereto and
incorporated herein by reference in its entirety.

         The furnishing of Exhibit 99 is not intended to constitute a
representation that such furnishing is required by Regulation FD or that the
information it contains includes material investor information that is not
otherwise publicly available. Statements in Exhibit 99 which are not statements
of historical fact are forward-looking statements within the "safe harbor"
provision of the Private Securities Litigation Reform Act of 1995. These
forward-looking statements are based on the information available to, and the
expectations and assumptions deemed reasonable by, Arch Coal at the time the
statements are made. Because these forward-looking statements are subject to
various risks and uncertainties, actual results may differ materially from those
projected in the statements. These expectations, assumptions and uncertainties
include: Arch Coal's expectation of continued growth in the demand for
electricity; belief that legislation and regulations relating to the Clean Air
Act and the relatively higher costs of competing fuels will increase demand for
its compliance and low-sulfur coal; expectation of continued improved market
conditions for the price of coal; expectation that Arch Coal will continue to
have adequate liquidity from its cash flow from operations, together with
available borrowings under its credit facilities, to finance Arch Coal's working
capital needs; a variety of operational, geologic, permitting, labor and weather
related factors; and the other risks and uncertainties which are described in
Arch Coal's periodic and other filings with the Securities and Exchange
