            Waste Connections Closes Previously Announced
             Acquisitions and Comments on Current Quarter

    FOLSOM, Calif.--(BUSINESS WIRE)--Sept. 17, 2003--Waste
Connections, Inc. (NYSE:WCN) today announced the closing of the two
previously announced acquisitions in California. These two
transactions include a large residential collection and recycling
franchise operation servicing a portion of San Jose, and a fully
integrated franchise operation in Red Bluff, with combined annualized
revenue of approximately $29 million. In addition, the Company has
completed six other acquisitions to date in the third quarter with
annual revenue totaling approximately $12 million. These additional
closed transactions include two collection and landfill operating
companies in Mississippi and a series of tuck-in acquisitions in Iowa,
Nebraska and South Dakota.
    Ronald J. Mittelstaedt, chairman and chief executive officer,
said, "We are especially pleased to announce the completion of the two
California transactions as these acquisitions further expand the
Company's revenue base in exclusive West Coast markets. So far this
year, we have closed transactions with total annualized revenues of
almost $50 million. These closed acquisitions represent an important
building block as we approach 2004. We remain comfortable with our
target of acquiring $60 million of annualized revenue for the year
given an increasing amount of acquisitions under active discussions.
    "Regarding the current quarter, we now expect revenue to be near
the upper end of our previous guidance and our operating income before
depreciation and amortization to be approximately 2% below the low end
of our previous guidance due primarily to a higher contribution of
revenues from new acquisitions, weaker than expected performance in
three of our competitive markets, and timing delays in completion of
certain capital projects in the Southeast due to heavy rainfalls which
has also increased expenses. Consistent with our previous guidance, we
expect to increase our internalization rate to 67%-68% by the end of
the quarter, exclusive of the impact from newly acquired operations."

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 materially
differ 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) competition or
unfavorable industry conditions could lead to a decrease in demand for
the Company's services and to a decline in prices realized by the
Company for its services, (2) the Company depends in part on
acquisitions for growth, it may be required to pay increased prices
for acquisitions, and it may experience difficulty in integrating and
deriving synergies from acquisitions, or finding acquisition targets
suitable to its growth strategy. (3) the Company may not always have
access to the additional capital that it may require for its growth
strategy or its cost of capital may increase, (4) governmental
regulations may require increased capital expenditures or otherwise
affect the Company's business, (5) companies that Waste Connections
acquires could have undiscovered liabilities, (6) large, long-term
collection contracts on which the Company depends may not be replaced
when they expire or are terminated, and (7) the Company is highly
dependent on the services of senior management, who would be difficult
or impossible to replace. These risks and uncertainties, as well as
others, are discussed in greater detail in the Company's filings with
the Securities and Exchange Commission, including its most recent
Annual Report on Form 10-K and its subsequent Quarterly Reports on
Form 10-Q. There may be additional risks that the Company does not
presently know 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.
