                    INFORMATION TO BE INCLUDED IN THE REPORT


Item 7.01.  Regulation FD Disclosure.

            In accordance with General Instruction B.2 of Form 8-K, the
            information furnished pursuant to this Item 7.01 shall not
            be deemed to be "filed" for the purposes of Section 18 of
            the Securities Exchange Act of 1934, as amended, or
            otherwise subject to the liabilities of that section, nor
            shall it be deemed incorporated by reference into any
            registration statement or other filing pursuant to the
            Securities Act of 1933, as amended, or the Exchange Act,
            except as otherwise expressly stated in such filing.

            During our earnings conference call on February 23, 2005, we
            highlighted the following outlook for the first quarter 2005.

            (Dollar amounts are approximations)

            For the first quarter of the year, we estimate our revenue to be
            approximately $164 million - $166 million, with intermodal
            services contributing approximately $10 million, our
            operating income to be approximately $37 million - $38
            million, our operating income before depreciation and
            amortization expense to be approximately $52 million - $53
            million and our depreciation and amortization expense to be
            approximately 9.0% of revenues.

            These estimates exclude the impact of any additional acquisitions
            that may be completed during the first quarter.

            Operating income before depreciation and amortization, a non-GAAP
            financial measure, is provided supplementally because it is
            widely used by investors as a valuation and liquidity
            measure in the solid waste industry. This measure should be
            used in conjunction with GAAP financial measures. Management
            uses operating income before depreciation and amortization
            as one of the principal measures to evaluate and monitor the
            ongoing financial performance of our operations. Other
            companies may calculate operating income before depreciation
            and amortization differently. Refer to the Non-GAAP
            Reconciliation Schedule contained in our fourth quarter and
            full year 2004 press release furnished in our Current Report
            on Form 8-K filed with the SEC on February 22, 2005, for a
            reconciliation of these items for the fourth quarter and
            full year 2004.

            Safe Harbor for Forward-Looking Statements

            Certain statements contained in this Current Report on Form 8-K
            are forward-looking in nature. These statements can be
            identified by the use of forward-looking terminology such as
            "believes", "expects", "may", "will", "should" or
            "anticipates" or the negative thereof or comparable
            terminology, or by discussions of strategy. Waste
            Connections' business and operations are subject to a
            variety of risks and uncertainties and, consequently, actual
            results may differ materially from those projected by any
            forward-looking statements. Factors that could cause actual
            results to differ from those projected include, but are not
            limited to, the following: (1) difficulties in making
            acquisitions, acquiring exclusive contracts and generating
            internal growth may cause the Company's growth to be slower
            than expected; (2) the Company's growth and future financial
            performance depend significantly on its ability to integrate
            acquired businesses into its organization and operations;
            (3) the Company's acquisitions may not be successful,
            resulting in changes in strategy, operating losses or a loss
            on sale of the business acquired; (4) the Company competes
            for acquisition candidates with other purchasers, some of
            which have greater financial resources than it does, and
            these other purchasers may be able to offer more favorable
            acquisition terms, thus limiting the Company's ability to
            grow through acquisition; (5) timing of acquisitions may
            cause fluctuations in the Company's quarterly results, which
            may cause its stock price to decline; (6) rapid growth may
            strain its management, operational, financial and other
            resources; (7) the Company may be unable to compete
            effectively with governmental service providers and larger
            and better capitalized companies, which may result in
            reduced revenues and lower profits; (8) the Company may lose
            contracts through competitive bidding, early termination or
            governmental action, which would cause its revenues to



            decline; (9) increases in the costs of labor, disposal, fuel
            or energy could reduce operating margins; and (10) increases
            in insurance costs and the amount that we self-insure for
            various risks could reduce our operating margins and
            reported earnings. These risks and uncertainties, as well as
            others, are discussed in greater detail in the Company's
            other filings with the Securities and Exchange Commission,
            including its most recent Annual Report on Form 10-K. There
            may be additional risks of which the Company is not
            presently aware or that it currently believes are immaterial
            which could have an adverse impact on its business. The
            Company makes no commitment to revise or update any
            forward-looking statements in order to reflect events or
            circumstances after the date any such statement is made.
