                           AMERICAN ECOLOGY ANNOUNCES
                         $0.25 PER SHARE ANNUAL DIVIDEND

                      COMPANY SETS SEPTEMBER 30 RECORD DATE

     BOISE, Idaho - President and Chief Executive Officer Stephen Romano today
announced that the Board of Directors of American Ecology Corporation [NASDAQ:
ECOL] has declared a $0.25 per common share annual dividend for stockholders of
record on September 30, 2004. The Company will pay the dividend on October 15,
2004.

     "Due to the strong operating leverage of its core waste disposal business,
we are confident American Ecology can deliver sustained earnings growth and pay
an annual dividend going forward," Romano stated, adding, "The Company's free
cash flow is sufficient to fund an annual dividend while also funding all of the
capital investments required to support its growth initiatives."

     Since a management change in late 2001, American Ecology has exited all
non-core businesses, resolved a series of longstanding lawsuits, improved
operational efficiency, reduced overhead costs and paid down debt. During this
time, the Company has also spent approximately $6.4 million to eliminate all
preferred stock and paid a former bank $5.5 million to purchase and retire an
outstanding warrant for approximately 8% of the Company's stock at a price of
$4.07 per underlying common share.

     "These recent efforts have greatly improved American Ecology's balance
sheet, simplified its capital structure and removed potentially dilutive
overhang on the Company's stock," commented Senior Vice President and Chief
Financial Officer Jim Baumgardner.

     On August 3, 2004 the Company reported 17,229,718 common shares
outstanding. Management estimates that approximately $4.3 million will be paid
out for this annual dividend. At June 30, 2004, the Company reported $9.6
million in cash and short-term investments.

     "The hard work of the past several years has produced a lean, focused
organization with strong free cash flow," Romano stated, concluding "American
Ecology is very pleased to be in a position to aggressively pursue growth while
also distributing this dividend to its shareholders."

Management will host an investor conference call on Wednesday, October 20, 2004
at 10 a.m. mountain time to discuss the financial results for the quarter and
