                      AMERICAN ECOLOGY POSTS $13.1 MILLION
                            IN 2004 OPERATING INCOME

            FOURTH QUARTER OPERATING INCOME INCREASES TO $3.4 MILLION

     BOISE, Idaho - Jim Baumgardner, Senior Vice President and Chief Financial
Officer of American Ecology Corporation [NASDAQ: ECOL], today announced
financial results for the three and twelve months ending December 31, 2004. For
the fourth quarter of 2004, the Company reported net income of $3.2 million or
$0.18 per fully diluted share compared to net income of $3.1 million or $0.17
per diluted share for the fourth quarter of 2003.  For the twelve months ending
December 31, 2004, the Company reported net income of $23.4 million, or $1.32
per share compared to a net loss of $8.7 million or ($0.52) per fully diluted
share in 2003. For 2004, the Company reported operating income of $13.1 million
or 35% higher than the $9.7 million in operating income posted in 2003.

     "American Ecology's core hazardous and radioactive waste treatment and
disposal business delivered another quarter of strong earnings," Baumgardner
stated, adding "The significant increase in operating income year over year
demonstrates that our growth strategy is working."

FOURTH QUARTER 2004
- -------------------

     Revenue for the fourth quarter of 2004 decreased to $13.5 million, down
$3.4 million from $16.9 million in 2003. This decrease in revenue reflected a
large New Jersey clean up project shipped to the Company's Idaho facility in
late 2003 which included a substantial transportation component and was not
fully replaced by increased disposal revenue from other customers in 2004.
Quarterly revenue was also adversely affected by a July 1, 2004 fire at the
Company's Robstown, Texas facility which required the facility to suspend waste
treatment operations. On December 1, 2004 the Texas facility resumed limited
treatment operations. As previously disclosed, Texas treatment revenue was
approximately $1 million per quarter prior to the fire.

     During the quarter, the Company recognized $431,000 of expected proceeds
from business interruption insurance which reflects the actual incremental
expenses incurred since July 1, 2004 directly resulting from the fire. The
Company's total business interruption claim is materially larger. Management
believes the full amount claimed is valid, and anticipates recognizing
additional income when its claim is


                                        1

fully resolved with its insurance carrier. The Company also impaired the assets
destroyed by the fire and recognized the insured value of such assets during
the quarter, resulting in a $275,000 net gain.

     "Future reported financial results will be affected until we resume full
treatment operations and the business interruption claim is resolved,"
Baumgardner noted.

     As reported on December 10, 2004, the Company increased its estimate for
closure and post-closure costs at its closed Sheffield, Illinois facility by
$715,000 based on updated analyses. The combination of lower revenue and the
increased closure estimate reduced gross profit to $5.1 million compared to
gross profit of $5.9 million in the fourth quarter of 2003. While gross profit
decreased, it did not decrease as much as revenue, allowing gross margin to
increase to 38% of revenue in the fourth quarter of 2004 compared to 35% of
revenue in the same quarter last year. This increase in gross margin reflects a
lower percentage of quarterly revenue derived from low-margin transportation
services.

     Selling, general & administrative expenses (SG&A) for the fourth quarter
decreased to $2.1 million or 16% of revenue, compared to $2.7 million, or 16%
of revenue in the same quarter last year. The decrease in fourth quarter SG&A
primarily reflects a $461,000 reduction in the Company's allowance for doubtful
accounts.

     "In 2004 the Company improved both the quality and turnover of its accounts
and substantially reduced receivable write-offs compared to prior years."
Baumgardner stated, adding "This progress allowed us to materially reduce our
allowance for bad debt while maintaining an adequate allowance for the future."

     The Company's number of days sales outstanding, a measure of accounts
receivable turnover, decreased to an average of 60 days outstanding for 2004,
down from 68 days in 2003. In 2004, the Company wrote off $67,000 of bad debt,
down from $228,000 in 2003.

     Despite lower revenue and the charge for the increased Illinois closed
site reserve, lower SG&A and recognition of a portion of the business
interruption claim allowed the Company to deliver operating income of $3.4
million, an 8% increase over the $3.1 million posted for the same quarter last
year.

TWELVE MONTHS 2004
- ------------------

     Revenue for the twelve months ending December 31, 2004 declined 5% to $54.2
million compared to $57.0 million for 2003. The decrease in revenue was
attributable to less transportation revenue, significantly decreased disposal
volume at the Company's Texas facility following the July 1 fire, a slight
decrease in the Idaho facility's disposal volume as certain projects were
delayed into 2005, and a lower average selling price for the Company's disposal
services. However, the lower volumes in


                                        2

Texas and Idaho were offset by an 80% increase in volume at the Company's
Beatty, Nevada facility.  Overall waste volumes were up 2.5% over the previous
year.

     2004 gross profit dipped only slightly to $23.3 million or 43% of revenue,
compared to gross profit of $23.6 million or 42% of revenue for 2003.  While
revenue decreased, gross profit remained at a similar level due to a higher
proportion of treatment and disposal revenue versus lower margin transportation
revenue in 2003. In 2004, treatment and disposal revenue represented 81% of
total revenue, up from 77% of total revenue in 2003.

     For the year, SG&A decreased to $10.6 million or $3.3 million lower than
2003. Lower 2004 SG&A costs reflect materially reduced legal spending, a
reduction in the allowance for doubtful accounts, and generally lower
administrative costs due to improved business systems and efficiencies. In 2003
SG&A was negatively impacted by $1.8 million in legal expense for the Company's
Ward Valley, California damages claim.

     As noted above, for the year ending December 31, 2004, the Company
reported operating income of $13.1 million, or a 35% increase over the $9.7
million operating income posted in 2003.

     Large one-time events in both years contributed to the large swing in 2004
net income. In 2003, the Company wrote off a $21 million deferred site
development asset following an adverse trial court ruling in the Ward Valley
litigation and expensed an additional $1.8 million for related legal fees. The
Company also expensed $2.5 million for discontinued operations at its former
Oak Ridge, Tennessee facility, and posted a $5 million gain on sale of its
Texas sanitary landfill in 2003. Following the June 2004 sale of the Oak Ridge
facility, the Company recognized approximately $1 million of income and
adjusted its valuation allowance on its deferred tax assets. This produced an
$11.3 million tax benefit in the second quarter of 2004. Lastly, the July 1,
2004 fire at the Texas facility had a material adverse impact on net income for
the year.

     "For the first time in over a decade, American Ecology entered the new year
fully focused on its core waste treatment and disposal business," stated
President and Chief Executive Officer Stephen Romano, adding, "With full
resumption of treatment services in Texas, continued efficient operation of all
four of our disposal facilities and a solid sales outlook, management is
targeting operating income growth of 15% for 2005."
