FOR IMMEDIATE RELEASE
---------------------


                 COVANTA ENERGY CORPORATION ANNOUNCES AMENDMENTS
                 TO REVOLVING CREDIT AND PARTICIPATION AGREEMENT


FAIRFIELD, NJ, SEPTEMBER 28, 2001 - Covanta Energy Corporation (NYSE: COV)
announced today that it had amended its Revolving Credit and Participation
Agreement with its lenders. The Company also said that, based on present
business conditions, it remained comfortable with the previous earnings guidance
it has provided to the investment community for 2001 - of $120 million of
recurring base Earnings Before Interest and Taxes (EBIT). The Company's outlook
for 2002 aggregates approximately $132 to $135 million of recurring base EBIT.
In addition, the Company also noted that Standard & Poor's Corp. had recently
rated Covanta as investment grade (BBB with stable outlook).

The amendments to the agreement include: adjustments to financial covenants to
reflect changes in the schedule of payments for past energy sales to California
utilities and the timing of the Company's remaining non-core asset sales;
agreement not to make investments in newly identified independent power projects
until maturity of the facility in May of 2002, consistent with the Company's
previously disclosed plans regarding new investments; and requisite approval of
at least 8 banks holding more than 60% of the aggregate revolving loan exposure
held by the 32 banks in the bank group as a condition to the issuance of letters
of credit the Company might be required to deliver were its credit rating
reduced below investment grade.

As previously reported, California utilities Pacific Gas & Electric (PG&E) and
Southern California Edison (SCE), a subsidiary of Edison International, as of
June 30, 2001, owed the Company a combined total of $77.6 million in past due
receivables. The Company has already established a reserve of $19.4 million
against this amount. The California utilities have been paying Covanta in full
for current energy sales since the spring. PG&E has made progress in its
bankruptcy proceeding, where Covanta's accounts receivables have been afforded
administrative status, to be paid in full with interest upon consummation of a
plan for reorganization by the bankruptcy court. SCE has executed an agreement
with the State of California that requires legislative approval in order to be
in a position to pay past due receivables. Absent the approval of that

agreement, SCE may also enter bankruptcy. Covanta believes that at this time its
reserve position on accounts receivable due from PG&E and SCE remains
sufficient.

Certain statements included in this news release are forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Forward-looking statements above
include, but are not limited to, expected earnings and future financial
performance. Although Covanta believes that its expectations are reasonable, it
can give no assurance that these expectations will prove to have been correct.
Factors that could cause Covanta's actual results to differ materially from
those contemplated in the forward-looking statements above include, among
others, the following:

      -     Economic, capital market and other business conditions affecting
            power generation enterprises specifically and commerce generally
            including interest, inflation and exchange rates; weather
            conditions; creditworthiness of customers and suppliers, changes in
            fuel costs and supply; unscheduled outages; environmental incidents;
            electric transmission restraints and risks and uncertainties
            associated with the recently deregulated energy industry;

      -     Trade, monetary, fiscal, taxation, energy regulation and
            environmental policies of governments, agencies and similar
            organizations in geographic areas where Covanta has a financial
            interest;

      -     Financial or regulatory accounting principles or policies imposed by
            the Financial Accounting Standards Board, the Securities and
            Exchange Commission, the Federal Energy Regulatory Commission and
            similar entities with regulatory oversight, including without
            limitation the impact of newly adopted FASB 133 relating to
            accounting for derivatives which is effective beginning January 1,
            2001. The impact of FASB 133 will vary between accounting periods
            based on changes in pricing of various items bought and sold by the
            Company.

      -     Cost and other effects of legal and administrative proceedings,
            settlements, investigations and claims;

      -     Limitations on Covanta's ability to control the development or
            operation of projects in which Covanta has less than 100% interest;

      -     The lack of operating history at development projects provides only
            a limited basis for management to project the results of future
            operations.
