Item 9.  Regulation FD Disclosure.

         In accordance with General Instruction B.2 of Form 8-K, the information
         furnished pursuant to this Item 9 shall not be deemed to be "filed" for
         the purposes of Section 18 of the Securities Exchange Act of 1934, as
         amended, nor shall it be deemed incorporated by reference into any
         registration statement or other filing pursuant to the Securities and
         Exchange Act of 1933, as amended, except as otherwise expressly stated
         in such filing.

         During our earnings conference call on April 22, 2004, we highlighted
the following outlook for the second quarter, 2004:

         (Dollar amounts are approximations and in millions)

                  For the second quarter of the year, we estimate our revenue to
                  be approximately $158 - $160, our operating income before
                  depreciation and amortization expense to be approximately
                  $53.5 - $54.5 of revenue, our depreciation and amortization
                  expense to be approximately 8.7% of revenue, and SG&A to be
                  around 9.5% of revenue. Additionally, in connection with the
                  redemption of our $150 million aggregate principal amount,
                  5.5% Convertible Subordinated Notes due 2006, we expect to
                  recognize an estimated $1.5 million of pre-tax expense, or
                  $1.1 million expense, net of taxes, in the second 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 financial performance 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 first quarter 2004 press
         release furnished in our Current Report on Form 8-K filed with the SEC
         on April 21, 2004, for a reconciliation of this item in the first

         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; and (8) the Company
         may lose contracts through competitive bidding, early termination or
         governmental action, which would cause its revenues to decline. 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.


Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
