AMERICAN ECOLOGY POSTS STRONG FIRST QUARTER OPERATING INCOME OF $6.2 MILLION

BOISE, Idaho April 18, 2006 – American Ecology Corporation [NASDAQ: ECOL] today announced that for the quarter ended March 31, 2006, net income was $4,179,000, or $0.23 per fully diluted share, compared to net income of $856,000, or $0.05 per fully diluted share in the first quarter of 2005.

Operating income was $6.2 million for the quarter, 355 percent higher than operating income of $1.4 million posted in the first quarter of 2005. All four of the Company’s operating facilities delivered improved profitability over the first quarter of 2005.

Revenue for the first quarter of 2006 increased 71 percent to $21.5 million, up from $12.6 million a year ago. This improvement reflects an 8 percent increase in average selling price and a 42 percent increase in the volume of waste disposed of at the Company’s hazardous waste facilities in Idaho, Nevada and Texas. Revenue at the Company’s low-level radioactive waste disposal facility in Washington also increased significantly due to an ongoing, non-rate regulated project.

Total waste volumes disposed were significantly higher than the first quarter of 2005, when waste shipments from several committed projects were delayed by weather and other factors.

“The operating leverage inherent in our business was evident in the quarter as higher waste volumes and improved railcar utilization rates delivered favorable financial results,” stated Stephen Romano, President and Chief Executive Officer. “Our strong first quarter performance was also notable given the small contribution from the Honeywell contract, which did not resume shipments from the New Jersey project’s main excavation phase until April 3, 2006,” Romano added.

Other direct operating costs for the quarter increased to $6.8 million, up from $5.5 million in the first quarter of 2005, reflecting increased labor and waste treatment additive costs to handle increased waste throughput. The Company also incurred higher costs for its recently expanded railcar fleet as well as project-specific railroad charges. Due to higher revenue, other direct operating costs declined to 31% of revenue in the first quarter of 2006 down from 44% a year ago.

Improved facility and railcar utilization pushed gross profit from $3.8 million or 31% of revenue in the first quarter of 2005 to $9.7 million, or 45% of revenue in the first quarter of 2006.

Selling, general & administrative expenses (SG&A) for the first quarter of 2006 were $3.5 million, or 16% of revenue, compared to SG&A of $2.5 million, or 20% of revenue, in the first quarter last year.

At quarter end, the Company had $17.3 million of cash and investments and $29.2 million of working capital. The Company’s $15 million line of credit was not used during the quarter.

For 2006, the Company continues to anticipate net earnings of between $0.72 and $0.82 per fully diluted share, in line with guidance first provided on December 5, 2005.

“We are pleased with American Ecology’s strong performance in what has historically been a slower quarter,” stated Michael Gilberg, Vice President and Controller. “The Company’s strong first quarter results biases us toward the top end of our 2006 guidance range,” Gilberg concluded.

On April 3, 2006, the Company declared a $0.15 per common share quarterly dividend for stockholders of record on April 14, 2006. This $2.7 million dividend will be paid using cash on hand on April 21, 2006.

Also on April 3, 2006, the Company self funded $4.5 million of non-operating disposal site closure and post-closure obligations, replacing the insurance policy which previously provided financial assurance for those sites. The insurance policy remains in effect, at a reduced premium, for financial assurance obligations at operating facilities.

The Company’s first quarter 2006 investor conference call will be held Wednesday, April 19, 2006 at 9:00 am Mountain Time. President and Chief Executive Officer Stephen Romano, Vice President and Controller Michael Gilberg and Vice President of Sales and Marketing Steven Welling will host the call.
