BOISE, ID -- (MARKET WIRE) -- December 7, 2006 -- American Ecology Corporation (NASDAQ: ECOL) today announced its earnings guidance and its dividend and capital spending plans for 2007.

2007 Guidance

Management currently expects the Company to generate earnings of between $0.92 and $1.02 per diluted share for 2007, which reflects projected year-over-year growth in operating income in the range of 11%-24%. This is consistent with long-term organic growth projections for operating income in the range of 15%.

2006 earnings guidance of $0.85 to $0.90 per diluted share was last updated by the Company on October 18, 2006. This estimate, which management reaffirmed today, includes a pretax benefit of approximately $704,000 from settlement of a prior year business interruption insurance claim, approximately $458,000 in other income from a gain on sale of land at a non-operating facility and reimbursement of legal expenses from a prior year matter. The insurance settlement and other income contributed approximately $0.04 to 2006 diluted earnings per share.

The Company expects 2007 capital expenditures up to $12 million, a reduction from 2006 capital expenditures expected to approximate $20 million. The 2007 capital plan is devoted primarily to disposal cell expansion and increased drum storage capacity at the Company's Texas facility, expanded waste treatment capacity at its Idaho and Nevada facilities, a potential rail transfer facility in northern New Jersey, and equipment replacement at all four operating sites.

"We anticipate continued operating income growth in 2007 as recent and ongoing capital investments allow us to more efficiently manage increasing waste volumes," President and Chief Executive Officer Stephen Romano commented. "The approximately $50 million of internally generated cash invested in the last three years to expand our state-of-the-art treatment, disposal and rail transport services also provides an excellent platform to aggressively pursue new business," Romano stated.

Increased Honeywell project margins based on a northern New Jersey transfer station are only reflected in the higher end of the 2007 guidance range. "We continue to work on a preferred rail site with the involved government and railroad representatives, and have largely completed engineering design work," Romano noted, adding, "We have not begun construction pending the outcome of these ongoing discussions, however, and are not projecting a facility availability date at this time."

The Company expects to use substantially all of its available net operating loss carryforwards by the end of 2006 and to begin using cash on hand to pay its 2007 tax liabilities. The Company expects its effective tax rate to approximate 39% (37% cash rate) for 2007.

The Company plans to announce fourth quarter and full year 2006 financial results on February 6, 2007. Management will host an investor conference call the following day to discuss these results and provide an operations update. Specifics on the call will be issued in advance.

2007 Dividend Plan

The Company also announced that its Board of Directors intends to continue paying a $0.15 per common share quarterly dividend in 2007, subject to the Company meeting applicable bank covenants. The Board approved payment of the next quarterly dividend on January19, 2007 to stockholders of record on January 12, 2007. The Company estimates that approximately $2.7 million in cash will be paid out for the upcoming quarterly dividend.

"We believe American Ecology's free cash flow will continue to be sufficient to pay the dividend while also funding planned capital projects and other growth initiatives in 2007," Romano concluded.
