Item 7.01  Regulation FD Disclosure.

      During our earnings  conference  call on July 24, 2007, we highlighted the
      following  outlook  for the third  quarter  2007 and updated the full year
      2007 outlook originally highlighted during our earnings conference call on
      February 13, 2007.

      (Dollar amounts are approximations)

      For  the  third  quarter  of the  year,  we  estimate  our  revenue  to be
      approximately  $244 million to $246  million.  Price and volume  growth is
      estimated to be approximately 9%. Depreciation and amortization expense is
      estimated  to be  approximately  8.7% of revenue  and we expect  operating
      income before  depreciation and  amortization  expense to be approximately
      $76  million  to  $77  million.  We  expect  net  interest  expense  to be
      approximately  $8.7  million.  Minority  interests  and other  expense are
      estimated to be a combined  1.7% of revenues.  We expect our effective tax
      rate to be 38.5% and our fully diluted share count to be  approximately 70
      million shares.

      For the full year,  revenue is estimated to be approximately $940 million.
      Operating  income  is  estimated  to be  approximately  21.7%  to 21.9% of
      revenue.

      These estimates  exclude the impact of any additional  acquisitions or any
      stock option or share repurchase activity 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)  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) 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; (14) 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; (15) 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;   (16)  Waste   Connections'
      decentralized decision-making structure could allow local managers to make
      decisions that adversely affect Waste Connections' operating results; (17)
      Waste  Connections  may incur  additional  charges  related to capitalized
      expenditures,  which  would  decrease  its  earnings;  (18) the outcome of
      audits  by  the  Internal  Revenue  Service  may  adversely  affect  Waste
      Connections;  (19) each  business that Waste  Connections  acquires or has
      acquired may have liabilities that Waste Connections fails or is unable to
      discover,  including  environmental  liabilities;   (20)  liabilities  for
      environmental damage may adversely affect Waste Connections'  business and
      earnings;   and  (21)  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.
