AMERICAN ECOLOGY SECOND QUARTER OPERATING INCOME UP 56 PERCENT TO $5.9 MILLION

Quarterly Revenue Increases 36 Percent
BOISE, Idaho July 19, 2005 – American Ecology Corporation [NASDAQ: ECOL] today reported net income of $3.7 million, or $0.21 per fully diluted share for the quarter ended June 30, 2005, compared to net income of $16 million, or $0.90 per fully diluted share a year ago. Included in last year’s results are non-operating gains of $12.2 million. Operating income for the quarter increased to $5.9 million versus $3.8 million for the second quarter of 2004.

Second Quarter Results
Revenue for the second quarter increased $5.0 million, or 36 percent, from $13.8 million a year ago to $18.8 million in 2005. The increase in revenue was primarily attributable to a 25 percent increase in disposal volume and an eight percent increase in average selling price. Revenue for all four of the Company’s operating sites increased over both the same quarter last year and the first quarter of 2005. The Company’s Idaho site experienced the largest increase, posting a 45 percent increase in quarterly disposal volume and a like increase in revenue.

“During the second quarter, a number of previously delayed clean-up projects began shipping in earnest,” stated Stephen Romano, President and Chief Executive Officer. “These shipments, combined with our ongoing business, allowed us to take advantage of the largely fixed cost nature of the disposal business,” he explained.

Increased shipments under bundled rail transportation and disposal contracts significantly improved utilization of the Company’s railcar assets, further contributing to profitability. “Our transportation and disposal price bundling strategy is proving a successful platform for growth,” continued Romano, adding “Based on ongoing projects and our current sales outlook, we are confident that American Ecology will achieve 15 percent growth in 2005 operating income over 2004.”

The combined result of higher revenue and a relatively smaller increase in direct costs was a 45 percent increase in gross profit from $6.3 million, or 46 percent of revenue, in the second quarter of 2004 to $9.2 million, or 49 percent of revenue in the second quarter of 2005.

Selling, general & administrative expenses (SG&A) for the second quarter increased to $3.4 million, or 18 percent of revenue, compared to SG&A of $2.6 million, or 19 percent of revenue in the second quarter last year. The dollar increase in SG&A was principally attributable to increased legal fees associated with the Honeywell contract and other legal matters, higher accounting fees associated with Sarbanes-Oxley internal controls compliance, higher director fees and expenses and a management incentive plan accrual.

The increase in disposal revenue more than outweighed the increased costs, pushing operating income higher by $2.1 million to $5.9 million, compared to $3.8 million in the second quarter of 2004.

“The combination of higher waste volumes and a more profitable service mix pushed our gross margin to almost 50 percent during the quarter,” stated Senior Vice President and Chief Financial Officer, Jim Baumgardner, adding, “All four of the Company’s operating disposal sites were profitable for the quarter, and all four showed improvement over results for the first quarter of 2005.”

For the quarter just ended, the Company reported after-tax net income of $3.7 million, or $0.21 per fully diluted share, compared to after-tax net income of $16 million, or $0.90 per fully diluted share a year ago. Quarterly net income in 2004 was positively affected by a $920,000 one time gain on the sale of the Company’s former Oak Ridge, Tennessee processing business and an $11.3 million release of a valuation allowance for deferred tax assets.

Year-to-Date Results
Revenue for the six months ended June 30, 2005 reached $31.3 million, up 13 percent from the first six months of 2004. Waste volumes year-to-date increased 14 percent over 2004. This increase in revenue was substantially offset by higher costs, including underutilized transportation assets in the first quarter and volume-related variable costs in the second quarter, resulting in operating income of $7.2 million, identical to the same period last year. For the first six months of 2005, the Company reported net income of $4.6 million, or $.26 per fully diluted share, compared to net income of $18.5 million, or $1.04 per fully diluted share for the first half of 2004.

At June 30, the Company reported $12.6 million in cash and investments on hand and working capital of $19.3 million.

Other Updates
On June 8, 2005, the Company announced the award of a contract to transport, treat and dispose of contaminated soils from a Honeywell International Inc. site in Jersey City, New Jersey. Depending on the volume of waste shipped off-site, which has been estimated at one million tons, and the Company’s ability to successfully perform under the contract, management estimates revenue in the range of $175 to $240 million over a four to five year period. The Company began receiving initial waste shipments under this contract in July 2005.

A significant portion of the revenue derived from the Honeywell contract will include value added transportation services. As a result, management expects that while revenue dollars will increase, the Company’s gross margin relative to revenue will decrease.

As previously announced, the Company may invest up to $12 million in capital expenditures to support the Honeywell contract. Management currently estimates that total capital spending in 2005 may reach $20 million principally for railcars, disposal capacity expansion in Idaho, and new treatment buildings in Texas and Nevada. The new treatment building in Texas is expected to be completed in the next 30-45 days, allowing for the resumption of full waste treatment services.

On May 26, 2005 the Company declared a $0.15 per common share quarterly dividend for stockholders of record on July 1, 2005. The Company paid $2.6 million for the declared quarterly dividend on July 15, 2005. The Company intends that shareholders of record on October 3, 2005 and January 2, 2006 will also receive a $0.15 per share dividend, subject to ongoing compliance with applicable bank covenants.

The Company’s second quarter 2005 investor conference call will be held Wednesday, July 20, 2005 at 10:00 am Mountain Time. President and Chief Executive Officer Stephen Romano, Senior Vice President and Chief Financial Officer Jim Baumgardner, Vice President and Controller Michael Gilberg and Vice President for Sales and Marketing Steve Welling will host the call. Interested parties are invited to submit questions in advance to info@americanecology.com, or by facsimile to 208.331.7900. To join the call, dial 1.877.331.8343.
