AMERICAN ECOLOGY THIRD QUARTER OPERATING INCOME INCREASES TO $6.9 MILLION, UP 168 PERCENT

Quarterly Revenue Increases 92 Percent on Higher Waste Receipts

BOISE, Idaho October 18, 2005 – American Ecology Corporation [NASDAQ: ECOL] today reported net income of $7.7 million or $0.43 per fully diluted share for the quarter ended September 30, 2005, compared to net income of $1.7 million or $0.10 per fully diluted share a year ago. Included in third quarter results is a $5.3 million pre-tax gain in other income associated with litigation settlement proceeds. Operating income for the quarter increased to $6.9 million, a 168 percent increase over the $2.6 million in operating income posted in the third quarter of 2004.

Third Quarter Results
Revenue for the third quarter increased to $24.8 million, an $11.9 million or 92 percent increase from the $12.9 million in revenue recognized a year ago. The increase in revenue reflects a 71 percent increase in disposal volume and slightly lower average selling price. Revenue and volume increased at all four of the Company’s operating disposal sites over the same quarter last year. The Company’s Idaho disposal site delivered the largest increase, posting a 95 percent increase in quarterly disposal volume and an 80 percent increase in disposal revenue.

“During the third quarter American Ecology continued to grow, receiving and disposing record waste volumes,” stated Stephen Romano, President and Chief Executive Officer, adding “Our focused, high-volume, low-overhead strategy is working. We are securing large clean-up jobs, continuing to provide quality service, and retaining key customers.”

Increased waste volumes reflect a combination of ongoing base business, a strong spring-summer clean-up project season, initiation of the Honeywell project and receipt of waste shipments from several large clean-up projects that were delayed in late 2004 and early 2005 by weather and other factors outside the Company’s control. Waste shipments under bundled rail transportation and disposal contracts continued to result in high utilization of the Company’s railcar assets, further contributing to the increased quarterly profitability.

Higher revenue was slightly offset by higher transportation and other direct costs. However, the Company still increased gross profit from $5.5 million, or 43 percent of revenue, in the third quarter of 2004 to $10.0 million, or 40 percent of revenue in the third quarter of 2005.

In dollars, selling, general & administrative expenses (SG&A) for the third quarter increased slightly to $3.1 million compared to SG&A of $3.0 million in the third quarter of 2004. However, SG&A dropped to 13 percent of revenue from 23 percent of revenue in the same quarter last year.

The substantially increased disposal revenue drove operating income to $6.9 million, $4.3 million higher than the $2.6 million of operating income posted in the third quarter of 2004.

Increased waste volumes combined with a favorable service mix and controlled spending were again key drivers in the Company’s financial results for the quarter.

“High volume throughput and the largely fixed cost nature of the disposal business drove our revenue and earnings growth,” stated Senior Vice President and Chief Financial Officer Jim Baumgardner, adding “All four of American Ecology’s operating disposal sites were profitable for the quarter and delivered improved results over the same quarter last year.”

During the quarter, the Company received an $11.8 million payment from the Central Interstate Low-Level Radioactive Waste Compact. This payment fully resolved the Company’s claim on proceeds from a settled lawsuit brought against the State of Nebraska for bad faith in the licensing process for a formerly proposed low-level radioactive waste disposal facility near Butte, Nebraska. The Company had previously recognized a $6.5 million deferred asset for its investment in the Nebraska project. Consequently, a pre-tax gain of $5.3 million was recognized in the third quarter as Other Income.

For the quarter just ended, the Company reported after-tax net income of $7.7 million, or $0.43 per fully diluted share, compared to after-tax net income of $1.7 million, or $0.10 per fully diluted share a year ago.

Year-to-Date Results
Revenue for the nine months ended September 30, 2005 reached $56.1 million, up $15.5 million or 38 percent over the first nine months of 2004. Waste receipts year-to-date increased 33 percent over 2004, and have already exceeded total 2004 waste receipts. The volume-driven increase in revenue was partially offset by higher costs, including underutilized transportation assets in the first quarter of 2005, and certain volume-related variable costs in the second and third quarters. However, growth in revenue at all four operating disposal facilities produced operating income of $14.1 million, 44 percent higher than the $9.8 million of operating income posted for the first nine months last year.

For the first nine months of 2005, the Company reported net income of $12.3 million, or $0.68 per fully diluted share, compared to net income of $20.2 million, or $1.14 per fully diluted share for the first nine months of 2004. Financial results for the first nine months of 2004 were 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.

At September 30, 2005 the Company reported $23.8 million in cash and investments on hand. At quarter-end, working capital was $33.3 million, up from $19.3 million at the end of the previous quarter.

Outlook
“Management expects to exceed its target of 15 percent annual growth in operating income in 2005,” Romano noted, concluding, “While we expect a solid fourth quarter, we have now received and disposed of much of the waste from previously delayed clean-up projects.”

Other Updates
American Ecology Corporation declared a $0.15 per common share quarterly dividend for stockholders of record on October 3, 2005. The Company paid $2.6 million for the declared quarterly dividend on October 14, 2005. The Company presently intends that shareholders of record on January 2, 2006 will also receive a $0.15 per share dividend subject to ongoing compliance with applicable bank covenants.

Management will host an investor conference call on Wednesday, October 19, 2005 at 10 a.m. mountain time to discuss financial results for the quarter. Chief Executive Officer Stephen Romano, Chief Financial Officer James Baumgardner, Vice President of Sales and Marketing Steve Welling, and Controller Michael Gilberg will present information and answer questions during the call.

AMERICAN ECOLOGY ANNOUNCES WASTE SHIPMENTS DELAYED AT NEW JERSEY SITE

Shipments Expected to Resume In 3 Months or Less

BOISE, Idaho, October 27, 2005 – Stephen Romano, President and Chief Executive Officer of American Ecology Corporation [NASDAQ:ECOL] today announced that waste shipments under the Company’s transport, treatment and disposal contract with Honeywell International Inc. for a site in Jersey City, New Jersey have been delayed.

Honeywell recently notified the Company that waste excavation associated with construction of a subsurface barrier wall surrounding the site is complete. Material from this initial excavation phase has been shipped off-site for disposal. Honeywell further notified the Company that shipments from the main, multi-year excavation would be delayed for up to 90 days, although shipments could resume earlier.

"Like other large remedial projects, the pace and timing of on-site excavation work and the availability of waste for shipment to American Ecology are beyond our control,” stated Romano, adding, “Our contract with Honeywell remains in full effect and we look forward to receiving substantially all of the waste removed from the Jersey City site once the main excavation resumes.”

American Ecology will assess Honeywell certain fees for not meeting minimum weekly shipment requirements as provided for under the Contract. The Company will also pay certain fees to its New Jersey subcontractor. Management is presently working with Honeywell and its subcontractors to minimize delay costs.

Awarded in June 2005, the contract commits Honeywell to provide American Ecology 99% of the chromite ore processing residues removed from the site during the upcoming main excavation phase.

Total waste volumes at the site have been estimated at approximately one million tons. On October 6, 2005 Honeywell filed a motion in U.S. District Court, District of New Jersey to reduce the amount of material removed from the site by 53%. The motion is presently under judicial review.

American Ecology Corporation, through its subsidiaries, provides radioactive, PCB, hazardous, and non-hazardous waste services to commercial and government customers throughout the United States, such as nuclear power plants, steel mills, medical and academic institutions and petro-chemical facilities. Headquartered in Boise, Idaho, the Company has disposal facilities in Idaho, Nevada, Washington and Texas, and is the oldest radioactive and hazardous waste services company in the United States.

This press release contains forward-looking statements that are based on management’s current expectations, beliefs, and assumptions about the industry and markets in which American Ecology Corporation and its subsidiaries operate. Actual results may differ materially from what is expressed herein. No assurance can be given that Honeywell will timely resume off-site shipments, ship volumes originally projected, or that the fees being assessed will cover all project delay costs. Nor can the Company provide assurances it will satisfactorily perform under the terms of the contract, meet its profitability objectives for the project, or successfully execute its overall business plan going forward. For information on other factors that could cause actual results to differ from expectations, please refer to American Ecology Corporation’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q filed with the Securities and Exchange Commission.
