                         AMERICAN ECOLOGY ANNOUNCES SALE
                  OF OAK RIDGE, TENNESSEE ASSETS TO TOXCO, INC.

        COMPANY ANNOUNCES JULY 21 SECOND QUARTER INVESTOR CONFERENCE CALL

     BOISE, Idaho - Stephen Romano, President and Chief Executive Officer of
American Ecology Corporation [NASDAQ: ECOL], today announced that on June 30,
2004 American Ecology completed the sale of principally all of the assets of its
discontinued low-level radioactive waste processing facility in Oak Ridge,
Tennessee to Toxco Inc., of Anaheim, California.

     "This transaction concludes a successful 2 and half year effort by American
Ecology to exit this and other non-core businesses, allowing us to focus on our
core hazardous and radioactive waste treatment and disposal business," Romano
said, continuing "The 16 acre, State-licensed Oak Ridge facility provides Toxco
with an excellent location and the infrastructure to expand their existing
business."

     Under the terms of the transaction, Toxco received all of the facility's
land, buildings, equipment and licenses, plus $1.65 million in cash in exchange
for assuming all environmental obligations, including the costs for future
closure and decommissioning of the facility at the end of its operational life.
The transaction relieved $4.6 million of environmental liabilities from American
Ecology's balance sheet and will result in a gain on sale of approximately $1.0
million, which will be reflected in the Company's financial statements as of
June 30, 2004.

     American Ecology acquired the Oak Ridge low-level radioactive waste
processing facility in 1994 and operated the business through subsidiary
American Ecology Recycle Center Inc. Commercial


                                        5

operations were discontinued in December 2002, followed by reductions in the
facility's labor force. All customer waste was removed from the facility by
July, 2003.

     "We're very pleased to close this chapter in American Ecology's history,"
Romano concluded.

     With the sale complete, the Company will re-evaluate its valuation
allowance against its deferred tax asset and its expected ability to utilize
those net operating loss carry-forwards specifically related to past operation
of the Oak Ridge facility.  This re-evaluation should result in a significant
tax benefit, which will be addressed in the Company's financial results for the
quarter ending June 30, 2004.

     American Ecology Corporation will announce financial results for the
quarter ending June 30, 2004 on Tuesday, July 20 at the close of trading on the
Nasdaq National Stock Market.   Company management will host an investor
conference call on Wednesday, July 21 at 10:00 a.m. Mountain Time to discuss
second quarter results and the financial impact of the Oak Ridge asset sale.
Interested parties may participate in the investor conference by calling
