The majority of our revenues are derived from fees charged for waste treated and disposed of at our owned facilities. We also manage the transportation of wastes to our facilities and we package waste, broker arrangements with other service providers and transport waste to those service providers' facilities. American Ecology was incorporated in Delaware in 1987. Our executive offices are located at 300 E. Mallard, Suite 300, Boise, ID 83706-6650, and our telephone number is (208) 331-8400. FORWARD LOOKING STATEMENTS Statements and information included in this Registration Statement on Form S-3 that are not purely historical are forward-looking statements within the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements regarding our expectations, intentions, beliefs and strategies regarding the future including sales, earnings per share, cost structure, market position, market growth opportunities and new products. We may make other forward-looking statements from time to time, including in press releases and public conference calls and webcasts. All forward-looking statements made by us are based on information available to us at the time the statements are made, and we assume no obligation to update any forward-looking statements. Actual results are subject to a number of risks and uncertainties that could cause actual results to differ materially from those included in the forward-looking statements. Some of these risks and uncertainties are discussed below in "Risk Factors." RISK FACTORS You should carefully consider the following risk factors and other information in or incorporated in this prospectus before deciding to invest in shares of our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not known to us or that we now think are immaterial may also impair our business operations. If any of the following risks actually occur, our business, financial condition and results of operations could be materially and adversely affected. If that occurs, the trading price of our common stock could decline, and you may lose all or part of your investment. KEY PERSONNEL We have a relatively flat management structure and we rely on the continued service of our senior management. The loss of services of any key management employee could adversely effect our business or the price of our securities. Also, our future success depends on our ability to identify, attract, hire, train and motivate other highly skilled personnel. Failure to do so may adversely affect future results. COMPLIANCE AND CHANGES WITH APPLICABLE LAWS AND REGULATIONS The changing regulatory framework governing our diverse business creates significant risks, including potential liabilities from violations of environmental statutes and regulations. Failure to timely obtain or comply with applicable federal, state and local governmental licenses, permits or approvals for our waste treatment and disposal facilities could prevent or inhibit us from operating our facilities and providing services, resulting in a potentially significant loss of revenue and earnings. Changes in laws or regulations or changes in the enforcement or interpretation of existing laws and regulations may require that we modify existing operating licenses or permits, or that we obtain additional approvals. Any new governmental requirements that raise compliance standards or require changes in operating practices or technology requirements may impose significant costs. Failure to comply with applicable statutes, regulations, licenses and permits may result in the imposition of substantial fines and penalties and could adversely affect our ability to carry on our business. Our revenues are primarily generated as a result of requirements imposed on our customers under federal and state laws, regulations, and programs to protect public health and the environment. If requirements to comply with these laws and regulations, particularly those relating to the treatment or disposal of PCB, hazardous, NORM/NARM and 2 low-level radioactive waste, were substantially relaxed or less vigorously enforced, demand for our services could materially decrease and our revenues could be significantly reduced. EXPOSURE TO LITIGATION Because our personnel routinely handle radioactive, PCB and hazardous materials, we may be subject to liability claims by employees, contractors and other third parties. There can be no assurance that our existing liability insurance is adequate to cover claims asserted against us or that we will be able to maintain adequate insurance in the future. Adverse rulings in ongoing legal matters could also have a material adverse effect on us. ACCESS TO CAPITAL We require cost-effective access to capital to implement our strategic and financial plan. If we cannot maintain access to capital or raise additional capital, we may need to delay or scale back planned infrastructure improvements or disposal capacity expansions. This could negatively impact our ability to generate earnings. We currently have cash and short-term investments on hand to fund our budgeted 2005 capital projects and we believe we have constructed sufficient disposal capacity to meet near-term needs. No assurance can be given, however, that we will continue to have cash on hand for these purposes or maintain cost-effective access to the capital markets. ACCESS TO INSURANCE AND FINANCIAL ASSURANCES We are required by license, permit, and prudence to maintain a variety of insurance instruments and financial assurances. Without cost-effective access to insurance and/or financial assurance markets, our ability to operate our facilities would be materially and adversely affected. Although we expect to renew these policies prior to expiration, no guarantee can be given that we will be able to renew or procure new financial assurance insurance on favorable terms. The inability to obtain cost-effective insurance and/or financial assurance could have a material adverse effect on us. IMPLEMENTATION OF NEW TECHNOLOGIES We expect to introduce new technologies at our facilities from time to time. We have experienced difficulties implementing new technologies in the past. If we cannot cost-effectively deploy new treatment technologies in response to market conditions and customer requirements, our business could be adversely affected. COMPETITIVE ENVIRONMENT We face competition from companies with much greater resources and potentially more cost-effective services. An increase in the number of commercial treatment or disposal facilities for hazardous or radioactive waste in the United States, or a decrease in the treatment or disposal fees charged by competitors could negatively affect our results of operations. Our business is heavily affected by waste tipping fees assessed by state regulatory entities. These fees, which vary from state to state, are periodically adjusted. Such adjustments may significantly impact the competitive environment in which we conduct business either positively or negatively. ECONOMIC CONDITIONS AFFECTING OUR CUSTOMERS Our hazardous waste facilities serve steel mills, refineries, chemical production plants and other basic industries that are, or may be, affected by general economic conditions. During periods of economic weakness, these industries may curtail production activities producing waste and/or delay spending on plant maintenance, waste clean-up work and other discretionary projects. POTENTIAL LOSS OF MAJOR CONTRACTS Customers periodically review their contracts with us and may, from time to time, opt not to renew or extend their disposal contracts. A loss of one or more of our large contracts could significantly reduce our revenues and negatively impact earnings, and materially and adversely affect our results of operations. 3 ABILITY TO COLLECT ON INSURANCE In July 2004, a fire at our Texas waste treatment facility substantially impaired our ability to operate that facility at full capacity and consequently our revenues in fiscal 2004 declined. While we believe our business interruption claim filed in response to the fire and other filed insurance claims are valid, we do not assure you that we can collect on amounts claimed. POTENTIAL FIRES OR OTHER INCIDENTS LIMITING OPERATIONS We are subject to unexpected occurrences related, or unrelated, to our daily handling of dangerous substances. A fire or other incident, such as the fire in July 2004 at our Texas waste treatment facility, could impair one or more of the facilities from performing their normal operations which could have a material adverse impact on us. ACCESS TO COST EFFECTIVE RAIL TRANSPORTATION SERVICE Revenue at our Grand View, Idaho facility is subject to potential risks from disruptions in rail transportation service. Large volume base business and event business at this facility frequently arrive by rail. Events such as strikes, natural disasters and other acts of God, war, or terror could delay shipments and reduce both volumes and revenues. In addition, rail car service may be limited by economic conditions, specifically including increasing demand for rail service, which may result in sustained periods of slower service and make it difficult to acquire sufficient rolling stock. These economic conditions could also result in lower volumes and revenues. During the second half of 2004 we experienced delays in receiving waste because rail transporters failed to meet anticipated schedules and because it was not practical to replace these transporters with other service providers. No assurance can be given that we can procure transportation services at historical rates. The lack of railcars, now and in the future, could limit our ability to implement our growth plan and increase revenue at our Grand View facility. UTILIZATION OF NET OPERATING LOSS CARRYFORWARDS As of March 31, 2005, we had federal net operating loss carryforwards of approximately $36 million. Section 382 of the Internal Revenue Code imposes an annual limitation on the amount of net operating loss carryforwards that may be used to offset taxable income when a corporation has undergone significant changes in its ownership. Our ability to utilize the net operating losses may be limited by the sale of common stock registered in this offering. To the extent our use of net operating loss carryforwards is limited by Section 382, our income would be subject to cash payments of income tax earlier than it would if we were able to fully use our net operating loss carryforwards. ABILITY TO PERFORM CONTRACTS AS REQUIRED Various contractual agreements require us to meet qualitative and quantitative performance criteria in providing waste services. The ability to meet the required performance criteria, in some cases, requires that we expend significant additional resources. If we were unable to meet the required performance criteria we could be subject to substantial monetary penalties and/or loss of the affected contracts. SIGNIFICANT SALES BY THE SELLING STOCKHOLDERS MAY CAUSE THE MARKET PRICE OF OUR STOCK TO DECLINE Sales of a substantial number of the shares covered by this offering, or the perception that such sales could occur, could cause the market price of our common stock to decline. While we have no current plans to raise capital through the sale of additional equity securities, the sale of the shares covered by this offering could impair our ability to raise capital through the sale of such securities. 4 WHERE YOU CAN FIND MORE INFORMATION - INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE We file annual, quarterly and special reports, proxy statements and other information with the Securities and Exchange Commission under the Securities Exchange Act of 1934.

Barker and Edward F. Heil are directors of American Ecology. Mr. Barker originally joined the Board of Directors in 1996. Mr. Barker did not stand for re-election to the Board at its May 2002 annual meeting, but returned to the Board to fill a vacancy created by a director who resigned in July 2002. Mr. Heil joined the Board of Directors in 1994. The remaining selling stockholders are Mr. Barker's daughter, Connie Barker, and trusts established for the benefit of Mr. Heil's children. The selling stockholders listed in the above table may have sold or transferred, in transactions exempt from the registration requirements of the Securities Act, some or all of their shares since the dates as of which the information in the above table was supplied to American Ecology. Information about the selling stockholders may change over time. Any changed information will be set forth in prospectus supplements, if required. Because the selling stockholders may offer all or some of their shares from time to time, American Ecology cannot accurately estimate the amount of shares of common stock that will be held by the selling stockholders upon the termination of any particular offering. See "Plan of Distribution." 6 PLAN OF DISTRIBUTION We are registering shares of common stock on behalf of the selling stockholders and we anticipate keeping this registration statement effective for a period of two years from its effective date. "Selling stockholders" includes donees, pledges, transferees or successors-in-interest selling securities received from a named selling stockholder as a gift, pledge or other non-sale related transfer after the date of this prospectus. All costs, expenses and fees (other than underwriting discounts, commissions or fees attributable to the sale of the shares or any counsel, accountants or other persons retained or employed by the selling stockholders) in connection with the registration of the shares of common stock offered by this prospectus will be borne by American Ecology. Brokerage commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by the selling stockholders. Sales of shares may be effected by the selling stockholders from time to time in one or more types of transactions, including block transactions - on the NASDAQ National Market System, - in the over-the-counter market, - in negotiated transactions, - through put or call options transactions relating to the shares, and - through short sales of shares, or a combination of these methods of sale or through any lawful manner, at fixed prices that may be changed, at market prices prevailing at the time of sale or at negotiated prices. The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares, nor is there an underwriter or coordinating broker acting in connection with the proposed sale of shares by the selling stockholders. The selling stockholders may sell shares directly to purchasers or to or through underwriters or broker-dealers, who may act as agents or principals. The underwriters or broker-dealers may receive compensation in the form of discounts, concessions or commissions from the selling stockholders and/or the purchasers of shares for whom the underwriters or broker-dealers may act as agents or to whom they sell as principal, or both. The amount and form of compensation for these services will be determined by the selling stockholders and the purchaser or purchasers, and may be in excess of customary commissions. The selling stockholders and any underwriters or broker-dealers that act in connection with the sale of shares might be deemed to be "underwriters" within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by these underwriters or broker-dealers and any profit on the resale of the shares sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act. The selling stockholders may agree to indemnify any underwriter, agent, or broker-dealer that participates in transactions involving sales of the shares against specified liabilities, including liabilities arising under the Securities Act. Because selling stockholders may be deemed to be "underwriters" within the meaning of Section 2(a)(11) of the Securities Act, the selling stockholders will be subject to the prospectus delivery requirements of the Securities Act, which may include delivery through the facilities of the Nasdaq National Market System pursuant to Rule 153 under the Securities Act. American Ecology has informed the selling stockholders that the anti-manipulative provisions of Regulation M of the Exchange Act may apply to their sales in the market. In addition to selling their shares under this prospectus, the selling stockholders also may resell all or a portion of their shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided they meet the criteria and conform to the requirements of that rule. 7 If the selling stockholders notify us of any material arrangement entered into with an underwriter or broker-dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, under Rule 424(b) under the Securities Act, disclosing - the name of each such selling stockholder and of the participating underwriter or broker-dealer; - the number of shares involved; - the price at which the shares were sold; - the commissions paid or discounts or concessions allowed to the underwriter or, broker-dealer; and - other facts material to the transaction. In addition, if we are notified by a selling stockholder that a donee, pledgee, transferee or other successor-in-interest intends to sell more than 500 shares, a supplement to this prospectus will be filed.

INDEMNIFICATION OF OFFICERS AND DIRECTORS We have broad powers to indemnify directors and officers against liabilities they may incur in these capacities under the Delaware General Corporation Law (the "DGCL"). Our Certificate of Incorporation requires that we indemnify officers and directors and eliminates directors' liability to American Ecology for monetary damages, in each case to the full extent allowed under the DGCL. Section 145(a) of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Section 145(b) of the DGCL provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if he or she acted under similar standards, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper. Section 145 of the DGCL further provides that (i) to the extent that a former or present director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith; (ii) indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and (iii) the corporation may purchase and maintain insurance on behalf of any present or former director, officer, employee or agent of the corporation or any person who at the request of the corporation was serving in such capacity for another entity against any liability asserted against such person and incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145. II-1 Article VII of our Certificate of Incorporation requires that we indemnify to the full extent permitted by the DGCL any person for liabilities incurred in his or her capacity as a director or officer of American Ecology, including service at our request in any capacity at another entity. We are obligated to pay in advance the person's expenses incurred in defending any proceeding in advance if the person agrees to repay the advance if it is determined ultimately that he or she is not entitled to be indemnified. Article VII also provides that the personal liability of our directors to American Ecology or its stockholders for monetary damages for any breach of fiduciary duty by the director as a director is limited or eliminated to the fullest extent permitted by the DGCL.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Boise, State of Idaho, on July 19, 2005.
