AMERICAN ECOLOGY ANNOUNCES RECORD REVENUE,
OPERATING INCOME AND DISPOSAL VOLUME FOR THIRD CONSECUTIVE YEAR

2008 Earnings Guidance Reflects 12% to 18% Operating Income Growth

Boise, Idaho – February 7, 2008 – American Ecology Corporation (NASDAQ: ECOL) today reported financial results for its fourth quarter and fiscal year ended December 31, 2007, with 2007 earnings per diluted share of $1.06.

Fourth Quarter Results

Net income was $4.9 million, or $0.27 per diluted share, for the fourth quarter of 2007, up 28% from net income of $3.8 million, or $0.21 per diluted share, earned in the fourth quarter of 2006. Operating income for the fourth quarter of 2007 increased 34% to $8.1 million, exceeding the $6.1 million of operating income earned in the fourth quarter of 2006.

Revenue for the fourth quarter of 2007 increased 21% to $45.9 million, up from $37.9 million in the same quarter last year. Waste volumes disposed at our Idaho, Nevada and Texas waste facilities in the fourth quarter of 2007 rose to a record 298,000 tons, an increase of 21% over the fourth quarter of 2006. Direct operating costs for the fourth quarter of 2007, which included rail and truck transportation expenses, variable costs for waste treatment additives, labor and benefits and disposal cell space amortization, rose 19% to $33.8 million, up from $28.5 million in the fourth quarter last year. The resulting operating leverage drove quarterly gross profit to $12.1 million in the fourth quarter of 2007, a 28% increase over gross profit of $9.4 million posted in the same quarter last year.

Selling, general and administrative (“SG&A”) expenses for the fourth quarter of 2007 were $3.9 million, or 9% of revenue, as compared to $3.4 million, also 9% of revenue, in the same quarter last year. The $548,000 increase in SG&A expenses reflects increased business activity, higher stock-based compensation expense, sales commissions, employee bonus compensation and administrative costs in support of the increased waste volumes received.

Other income was $241,000 for the fourth quarter of 2007 and consisted primarily of interest and royalty income. This compares to other income of $352,000 for the fourth quarter of 2006, which consisted of interest income, royalty income and proceeds from an easement agreement.

The Company’s effective income tax rate was 42.0% for the fourth quarter of 2007 compared to 40.9% for the fourth quarter of 2006. The higher effective tax rate in the fourth quarter of 2007 reflected a higher federal statutory rate as a result of the increased level of earnings as well as year end adjustments related to higher non-tax-deductible expenses on incentive based stock option awards and deferred taxes.

At December 31, 2007, we had $14.8 million of cash and short-term investments and $11.0 million of our $15.0 million line of credit was unused. The remaining $4.0 million was issued as a standby letter of credit providing collateral for financial assurance policies for future closure and post-closure obligations.

“We closed out 2007 with strong quarterly earnings, allowing us to deliver record revenue and operating income for the year,” commented President and Chief Executive Officer Stephen Romano.

Fiscal Year 2007 Results

Net income for the year ended December 31, 2007 was $19.4 million, or $1.06 per diluted share, up 22% from net income of $15.9 million, or $0.87 per diluted share, earned for the year ended December 31, 2006. This exceeded previous Company guidance of $1.02 to $1.05 per diluted share. Operating income for 2007 was $30.9 million, up 26% from operating income of $24.5 million for 2006.

Revenue for 2007 was $165.5 million, up 42% from revenue of $116.8 million in 2006. This growth reflects higher revenue at our Idaho, Nevada, and Texas operations, including increased revenue from bundled rail transportation and disposal contracts at our Idaho facility.

Disposal volumes in 2007 climbed to a record 1.1 million tons, driving gross profit to $45.5 million for 2007, up 24% from $36.6 million of gross profit in 2006. All four operating facilities increased disposal volumes over 2006, reflecting growth in multiple service lines.

Direct operating costs for 2007 were $120.0 million, up from $80.2 million for 2006. This reflects higher rail and truck transportation expenses on higher waste volumes, higher variable costs for waste treatment additives, disposal cell amortization, labor and benefits and equipment maintenance.

SG&A expenses for the year ended December 31, 2007 were $14.6 million, or 9% of revenue, as compared to $12.8 million, or 11% of revenue, for the year ended December 31, 2006.

Other income was $851,000 for the year ended December 31, 2007 consisting primarily of interest income and royalty income. In 2006, other income was $1.4 million which included interest income, reimbursement of legal fees from a prior year insurance litigation matter and a gain on sale of excess property.

2008 Earnings Guidance

Management projects earnings of $1.17 to $1.23 per diluted share for 2008, with operating income projected to grow 12% to 18% over 2007. The Company expects its effective annual tax rate to be 39.2% in 2008.

For 2008, capital expenditures are planned in the range of $11 to $12 million, a reduction from 2007 capital expenditures of approximately $15 million. Capital spending in 2008 will be devoted primarily to the construction of additional disposal space at our Texas and Nevada facilities and the introduction of thermal treatment and recycling services at our Texas facility.

“In 2007, we completed a three year, $55 million infrastructure expansion capital campaign to increase waste throughput capacity,” Romano commented. “We believe these past infrastructure investments combined with the introduction of thermal treatment and recycling services at our Texas facility will provide a sold platform for double digit operating income growth in 2008.”

2008 Dividend Plan

On January 2, 2008 the Company declared a $0.15 per common share quarterly dividend for stockholders of record on January 11, 2008. This $2.7 million dividend was paid on January 18, 2008 using cash on hand. The Company’s Board of Directors intends to pay a $0.15 per common share quarterly dividend for the balance of 2008, subject to satisfying applicable bank covenants.
