Item 7.01  Regulation FD Disclosure.

         During our earnings conference call on July 27, 2006, we highlighted
         the following outlook for the third quarter and full year 2006.

         (Dollar amounts are approximations)

         For the third quarter of the year, we estimate our revenue to be
         approximately $214 million to $216 million, assuming about 5% price
         growth and 2% volume growth at the mid-point. We expect selling,
         general and administrative expenses to be a little less than 10% of
         revenue, about 0.50% of which is related to stock-based compensation
         costs. Depreciation and amortization expense is estimated to be
         approximately 9.1% of revenue and operating income before depreciation
         and amortization expense to be approximately 30.5% of revenue. We
         expect net interest expense to be approximately $7.8 million and
         current all-in cost of debt to be approximately 4.9%. Minority
         interests expense is expected to be approximately 1.5% of revenues. We
         expect our effective tax rate to be 34.5% and our fully diluted share
         count to be approximately 46.7 million shares.

         For the full year, revenue is estimated to be approximately $820
         million. We expect operating income before depreciation and
         amortization to be approximately $245 million, which includes the $3.8
         million insurance charge recorded in the second quarter of 2006 and
         approximately $3.5 million for higher fuel and related costs than
         forecasted earlier in the year.

         These estimates exclude the impact of any additional acquisitions or
         any share repurchases that may be completed during the remainder of the
         year.

         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) efforts by
         labor unions could divert management attention and adversely affect
         operating results; (5) increases in insurance costs and the amount that
         Waste Connections self-insures for various risks could reduce its
         operating margins and reported earnings; (6) Waste Connections may lose
         contracts through competitive bidding, early termination or
         governmental action; (7) the geographic concentration of Waste
         Connections' business makes its results vulnerable to economic and
         seasonal factors affecting the regions in which it operates; (8)
         competition for acquisition candidates, consolidation within the waste
         industry and economic and market conditions may limit Waste
         Connections' ability to grow through acquisitions; (9) Waste
         Connections' growth and future financial performance depend
         significantly on its ability to integrate acquired businesses into its
         organization and operations; (10) Waste Connections' acquisitions may
         not be successful, resulting in changes in strategy, operating losses
         or a loss on sale of the business acquired; (11) 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; (12) 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; (13) 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; (14) Waste Connections' decentralized
         decision-making structure could allow local managers to make decisions
         that adversely affect Waste Connections' operating results; (15) Waste
         Connections' financial results are based upon estimates and assumptions
         that may differ from actual results; (16) Waste Connections may incur
         additional charges related to capitalized expenditures, which would
         decrease its earnings; (17) each business that Waste Connections
         acquires or has acquired may have liabilities that Waste Connections
         fails or is unable to discover, including environmental liabilities;
         and (18) 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.
