AMERICAN ECOLOGY POSTS OPERATING INCOME OF $1.4 MILLION IN FIRST QUARTER

BOISE, Idaho April 19, 2005 – American Ecology Corporation [NASDAQ: ECOL] today announced financial results for the quarter ending March 31, 2005. For the quarter, the Company reported net income of $856,000 or $0.05 per fully diluted share, compared to net income of $2.4 million, or $0.14 per fully diluted share a year ago. Operating income was $1.4 million for the quarter versus $3.4 million for the first quarter of 2004.

Revenue for the first quarter of 2005 was $12.6 million, compared to $13.9 million a year ago. This decrease in revenue was primarily due to slightly lower average selling prices and decreased transportation revenue. While waste volumes at the Company’s three hazardous waste sites remained relatively flat, higher operating costs were incurred in anticipation of waste shipments from contracts that were delayed due to weather, funding or other project-specific delays. Additionally, treatment revenue at the Company’s Texas facility was down quarter to quarter pending availability of the new treatment building now under construction. Revenue at the Company’s low-level radioactive waste disposal facility in Washington also declined due to lower rate-regulated waste volumes for the quarter. The Company also incurred transportation-related expenses in the quarter just ended to secure preferred long-term access to two east coast rail transfer facilities to better compete for large remediation projects.

“Confirming what we disclosed last month, first quarter results were lower than planned due to delayed shipments but the Company did not lose any major forecasted projects,” stated Stephen Romano, President and Chief Executive Officer. “While the costs of a temporarily underutilized rail fleet and securing east coast rail transfer points negatively affected first quarter results, we are well positioned to execute our growth strategy based on bundling of transportation and disposal services to increase waste volume throughput at our operating facilities,” he added.

All of the delayed first quarter 2005 projects are either shipping or expected to ship in the second quarter and the Company reaffirms its previous earnings guidance for the year. “We expect to receive and dispose of the delayed waste shipments during the balance of 2005 and continue to project 15% growth in operating income for the year,” Romano commented.

Direct costs for the quarter increased to $8.7 million from $7.6 million in the first quarter of 2004. Higher direct costs reflected increased labor, transportation and waste treatment additive costs at the Company’s Beatty, Nevada and Grand View, Idaho hazardous waste facilities. Higher transportation costs reflect fuel surcharges, an expanded railcar fleet, increased railcar operating lease expenses, and mobilization costs incurred in anticipation of the aforementioned large remediation projects now underway. Only a portion of these expenses could be passed on to customers.

The combined result of lower revenue and higher direct costs was a 39% decrease in gross profit from $6.3 million (45% of revenue) in the first quarter of 2004 to $3.8 million (31% of revenue) in the first quarter of 2005.

Selling, general & administrative expenses (SG&A) for the first quarter decreased to $2.5 million, or 20% of revenue, compared to SG&A of $2.9 million or 21% of revenue in the first quarter last year. SG&A expenses dropped despite the $105,000 spent in the first quarter of 2005 to comply with Sarbanes-Oxley Section 404 Internal Control requirements.

Reduced revenue and higher direct costs outweighed reductions in SG&A, lowering operating income by $2.0 million to $1.4 million, below the $3.4 million in operating income posted in the first quarter of 2004.

“Despite the lower quarterly operating income, cash flow remained solid and the Company’s financial condition continues to be strong,” stated Jim Baumgardner, Senior Vice President and Chief Financial Officer.

At quarter end, the Company had $13.2 million of cash and investments on hand and working capital of $17.2 million.

Management and Moss Adams LLP, the Company’s independent registered public accounting firm, have concluded that the Company’s internal controls over financial reporting were effective at December 31, 2004 and will report no material weaknesses. The Company will file an Amended Form 10K with the Securities and Exchange Commission on or prior to May 2, 2005 with the required internal control opinions.

The Company’s first quarter 2005 investor conference call will be held Wednesday, April 20, 2005 at 10:00 am Mountain Time. President and Chief Executive Officer Stephen Romano, Senior Vice President and Chief Financial Officer Jim Baumgardner, and Vice President and Controller Michael Gilberg will host the call.
