Item 7.01  Regulation FD Disclosure.

          During our earnings conference call on February 13, 2007, we
          highlighted the following outlook for the first quarter and full year
          2007.

          (Dollar amounts are approximations)

          For the first quarter of the year, we estimate our revenue to be
          approximately $215 million to $217 million. Operating income is
          estimated to be approximately 20.5% of revenue. Depreciation and
          amortization expense is estimated to be approximately 9.0% of revenue,
          and operating income before depreciation and amortization expense to
          be approximately $63.5 million to $64.5 million, or a little above
          29.5% of revenue at the mid-point. Equity-based compensation is
          estimated to be $1.5 million. We expect net interest expense to be
          approximately $7.8 million. Minority interests expense is estimated to
          be approximately 1.5% of revenues. We expect our fully diluted share
          count to be approximately 46.9 million shares, excluding the impact of
          any share repurchase activity during the quarter.

          For the full year, we estimate our revenue to be approximately $920
          million to $930 million. We expect selling, general and administrative
          expenses to be approximately 10.2% of revenue, subject to quarterly
          fluctuations. Depreciation and amortization expense is estimated to be
          approximately 9.0% of revenue, subject to quarterly fluctuations, and
          operating income before depreciation and amortization expense to be
          approximately $277.5 million to $280 million, or about 30.2% of
          revenue. Equity-based compensation is estimated to be approximately
          $5.7 million. Operating income is estimated to be approximately 21.2%
          of revenue, subject to quarterly fluctuations. We expect net interest
          expense to be approximately $33.5 million. Minority interests expense
          is estimated to be approximately 1.6% of revenues. We expect our
          effective tax rate to be 38.0%, subject to quarterly fluctuations, and
          our average fully diluted share count to be approximately 45.8 million
          shares assuming $100 million of stock is repurchased during the year.
          Net cash provided by operating activities is estimated to be
          approximately 24% of revenue, subject to quarterly fluctuations. Our
          capital expenditures are estimated to be approximately $115 million.

          These estimates exclude the impact of any additional acquisitions or
          any stock option activity that may be completed during the remainder
          of the year. These estimates also exclude the impact of the declared
          three-for-two stock split in the form of a 50% stock dividend
          announced on February 12, 2007.

          Operating income before depreciation and amortization is considered a
          non-GAAP financial measure, and is provided supplementally because it
          is widely used by investors as a valuation and liquidity measure in
          the solid waste industry. It is not a substitute for, and should be
          used in conjunction with, GAAP financial measures. Management uses
          operating income before depreciation and amortization as a principal
          measure to evaluate and monitor the ongoing financial performance of
          our operations. Other companies may calculate this measure
          differently.



          Safe Harbor for Forward-Looking Statements

          Certain statements contained in this report are forward-looking in
          nature. These statements can be identified by the use of
          forward-looking terminology such as "believes," "expects," "may,"
          "will," "should," "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) Waste Connections may be unable
          to compete effectively with larger and better capitalized companies
          and governmental service providers; (2) increases in the price of fuel
          may adversely affect Waste Connections' business and reduce its
          operating margins; (3) increases in labor and disposal and related
          transportation costs could impact Waste Connections' financial
          results; (4) increases in insurance costs and the amount that Waste
          Connections self-insures for various risks could reduce its operating
          margins and reported earnings; (5) Waste Connections' financial
          results are based upon estimates and assumptions that may differ from
          actual results; (6) efforts by labor unions could divert management
          attention and adversely affect operating results; (7) Waste
          Connections may lose contracts through competitive bidding, early
          termination or governmental action; (8) Waste Connections' results are
          vulnerable to economic conditions and seasonal factors affecting the
          regions in which it operates; (9) Waste Connections may be subject in
          the normal course of business to judicial and administrative
          proceedings that could interrupt its operations, require expensive
          remediation and create negative publicity; (10) competition for
          acquisition candidates, consolidation within the waste industry and
          economic and market conditions may limit Waste Connections' ability to
          grow through acquisitions; (11) Waste Connections' growth and future
          financial performance depend significantly on its ability to integrate
          acquired businesses into its organization and operations; (12) Waste
          Connections' acquisitions may not be successful, resulting in changes
          in strategy, operating losses or a loss on sale of the business
          acquired; (13) Waste Connections' Amended and Restated Revolving
          Credit and Term Loan Agreement and other factors and considerations
          may limit the number of shares repurchased under Waste Connections'
          stock repurchase program; (14) because Waste Connections depends on
          railroads for its intermodal operations, its operating results and
          financial condition are likely to be adversely affected by any
          reduction or deterioration in rail service; (15) Waste Connections'
          intermodal business could be adversely affected by steamship lines
          diverting business to ports other than those Waste Connections
          services, or by heightened security measures or actual or threatened
          terrorist attacks; (16) Waste Connections depends significantly on the
          services of the members of its senior and district management team,
          and the departure of any of those persons could cause its operating
          results to suffer; (17) Waste Connections' decentralized
          decision-making structure could allow local managers to make decisions
          that adversely affect Waste Connections' operating results; (18) Waste
          Connections may incur additional charges related to capitalized
          expenditures, which would decrease its earnings; (19) the outcome of
          audits by the Internal Revenue Service may adversely affect Waste
          Connections; (20) each business that Waste Connections acquires or has
          acquired may have liabilities that Waste Connections fails or is
          unable to discover, including environmental liabilities; (21)
          liabilities for environmental damage may adversely affect Waste
          Connections' business and earnings; and (22) the adoption of new
          accounting standards or interpretations could adversely impact Waste
          Connections' financial results. These risks and uncertainties, as well
          as others, are discussed in greater detail in Waste Connections'
          filings with the Securities and Exchange Commission, including its
          most recent Annual Report on Form 10-K. There may be additional risks
          of which Waste Connections is not presently aware or that it currently
          believes are immaterial which could have an adverse impact on its
          business. Waste Connections makes no commitment to revise or update
          any forward-looking statements in order to reflect events or
          circumstances that may change.
