RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risks described below before making an investment decision, as well as the risks and other information included and incorporated by reference in the applicable prospectus supplement when determining whether or not to purchase the securities offered under this prospectus and the applicable prospectus supplement. You should also refer to the other information in this prospectus incorporated by reference into this prospectus and the additional information in the other reports we file with the Securities and Exchange Commission (“SEC”).

If any of the following risks actually occur, our business, results of operations and financial condition could suffer. In that event, the trading price of our common stock could decline, and you may lose all or part of your investment in our common stock. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements.

Risks Relating to our Operations

Our insurer that provides our financial assurance that we are required have in order to operate our permitted treatment, storage and disposal facility has experienced financial difficulties.

It has been publicly reported that American International Group, Inc. (“AIG”), has experienced significant financial difficulties and is continuing to experience significant financial difficulties. A subsidiary of AIG provides our finite risk insurance policies which provide financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. We are required to provide and to maintain financial assurance that guarantees to the state that in the event of closure of our permitted facilities will be closed in accordance with the regulations. The policies provide a maximum of $35,000,000 of financial assurance coverage of which the coverage amount totals $32,515,000 at December 31, 2008. In March 2009, the policies were increased to provide a maximum of $39,000,000 of financial assurance coverage of which the coverage amounts totals $37,936,000. This additional increase was the result of additional financial assurance coverage requirement for our DSSI subsidiary to commercially store and dispose of PCB wastes under a permit issued by the EPA on November 26, 2008. The AIG subsidiary also provides other operating insurance policies for the Company and our subsidiaries. In the event of a failure of AIG, this could materially impact our operations and our permits which we are required to have in order to operate our treatment, storage, and disposal facilities.

If we cannot maintain adequate insurance coverage, we will be unable to continue certain operations.

Our business exposes us to various risks, including claims for causing damage to property and injuries to persons that may involve allegations of negligence or professional errors or omissions in the performance of our services. Such claims could be substantial. We believe that our insurance coverage is presently adequate and similar to, or greater than, the coverage maintained by other companies in the industry of our size. If we are unable to obtain adequate or required insurance coverage in the future, or if our insurance is not available at affordable rates, we would violate our permit conditions and other requirements of the environmental laws, rules, and regulations under which we operate. Such violations would render us unable to continue certain of our operations. These events would have a material adverse effect on our financial condition.

The inability to maintain existing government contracts or win new government contracts over an extended period could have a material adverse effect on our operations and adversely affect our future revenues.

A material amount of our Nuclear Segment's revenues are generated through various U.S. government contracts or subcontracts involving the U.S. government. Our revenues from governmental contracts and subcontracts relating to governmental facilities within our Nuclear Segment were approximately $43,464,000 and $30,000,000, representing 57.6% and 46.5%, respectively, of our consolidated operating revenues from continuing operations for 2008 and 2007. Most of our government contracts or our subcontracts granted under government contracts are awarded through a regulated competitive bidding process. Some government contracts are awarded to multiple competitors, which increase overall competition and pricing pressure and may require us to make sustained post-award efforts to realize revenues under these government contracts. All contracts with, or subcontracts involving, the federal government are terminable, or subject to renegotiation, by the applicable governmental agency on 30 days notice, at the option of the governmental agency. If we fail to maintain or replace these relationships, or if a material contract is terminated or renegotiated in a manner that is materially adverse to us, our revenues and future operations could be materially adversely affected.

Failure of our Nuclear Segment to be profitable could have a material adverse effect.

Our Nuclear Segment has historically been profitable. With the divestitures of certain facilities within our Industrial Segment and the acquisition of our Perma-Fix Northwest Richland, Inc. (“PFNWR”) within our Nuclear Segment in June 2007, the Nuclear Segment represents the Company’s largest revenue segment. The Company’s main objectives are to increase focus on the efficient operation of our existing facilities within our Nuclear Segment and to further evaluate strategic acquisitions within the Nuclear Segment. If our Nuclear Segment fails to continue to be profitable in the future, this could have a material adverse effect on the Company’s results of operations, liquidity and our potential growth.

Our existing and future customers may reduce or halt their spending on nuclear services with outside vendors, including us.

A variety of factors may cause our existing or future customers (including the federal government) to reduce or halt their spending on nuclear services from outside vendors, including us. These factors include, but are not limited to:

accidents, terrorism, natural disasters or other incidents occurring at nuclear facilities or involving shipments of nuclear materials;

failure of the federal government to approve necessary budgets, or to reduce the amount of the budget necessary, to fund remediation of U.S. Department of Energy (“DOE”) and U.S. Department of Defense (“DOD”) sites;

civic opposition to or changes in government policies regarding nuclear operations; or

a reduction in demand for nuclear generating capacity.

These events could result in or cause the federal government to terminate or cancel its existing contracts involving us to treat, store or dispose of contaminated waste at one or more of the federal sites since all contracts with, or subcontracts involving, the federal government are terminable upon or subject to renegotiation at the option of the government on 30 days notice. These events also could adversely affect us to the extent that they result in the reduction or elimination of contractual requirements, lower demand for nuclear services, burdensome regulation, disruptions of shipments or production, increased operational costs or difficulties or increased liability for actual or threatened property damage or personal injury.

Economic downturns (i.e. the current economic recession) and/or reductions in government funding could have a material negative impact on our businesses.

Demand for our services has been, and we expect that demand will continue to be, subject to significant fluctuations due to a variety of factors beyond our control, including the current economic recession and conditions, inability of the federal government to adopt its budget or reductions in the budget for spending to remediate federal sites due to numerous reasons, including, without limitation, the substantial deficits that the federal government has and is continuing to incur. During economic downturns, such as the current economic recession, and large budget deficits that the federal government and many states are experiencing, the ability of private and government entities to spend on nuclear services may decline significantly. Although the recently adopted economic stimulus package provides for substantial funds to remediate federal nuclear sites, we cannot be certain that economic or political conditions will be generally favorable or that there will not be significant fluctuations adversely affecting our industry as a whole. In addition, our operations depend, in large part, upon governmental funding, particularly funding levels at the DOE. Significant reductions in the level of governmental funding (for example, the annual budget of the DOE) or specifically mandated levels for different programs that are important to our business could have a material adverse impact on our business, financial position, results of operations and cash flows.

The loss of one or a few customers could have an adverse effect on us.

One or a few governmental customers or governmental related customers have in the past, and may in the future, account for a significant portion of our revenue in any one year or over a period of several consecutive years. Because customers generally contract with us for specific projects, we may lose these significant customers from year to year as their projects with us are completed. Our inability to replace the business with other projects could have an adverse effect on our business and results of operations.

As a government contractor, we are subject to extensive government regulation, and our failure to comply with applicable regulations could subject us to penalties that may restrict our ability to conduct our business.

Our governmental contracts, which are primarily with the DOE or subcontracts relating to DOE sites, are a significant part of our business. Allowable costs under U.S. government contracts are subject to audit by the U.S. government. If these audits result in determinations that costs claimed as reimbursable are not allowed costs or were not allocated in accordance with applicable regulations, we could be required to reimburse the U.S. government for amounts previously received.

Governmental contracts or subcontracts involving governmental facilities are often subject to specific procurement regulations, contract provisions and a variety of other requirements relating to the formation, administration, performance and accounting of these contracts. Many of these contracts include express or implied certifications of compliance with applicable regulations and contractual provisions. If we fail to comply with any regulations, requirements or statutes, our existing governmental contracts or subcontracts involving governmental facilities could be terminated or we could be suspended from government contracting or subcontracting. If one or more of our governmental contracts or subcontracts are terminated for any reason, or if we are suspended or debarred from government work, we could suffer a significant reduction in expected revenues and profits. Furthermore, as a result of our governmental contracts or subcontracts involving governmental facilities, claims for civil or criminal fraud may be brought by the government or violations of these regulations, requirements or statutes.

Loss of certain key personnel could have a material adverse effect on us.

Our success depends on the contributions of our key management, environmental and engineering personnel, especially Dr. Louis F. Centofanti, Chairman, President, and Chief Executive Officer. The loss of Dr. Centofanti could have a material adverse effect on our operations, revenues, prospects, and our ability to raise additional funds. Our future success depends on our ability to retain and expand our staff of qualified personnel, including environmental specialists and technicians, sales personnel, and engineers. Without qualified personnel, we may incur delays in rendering our services or be unable to render certain services. We cannot be certain that we will be successful in our efforts to attract and retain qualified personnel as their availability is limited due to the demand for hazardous waste management services and the highly competitive nature of the hazardous waste management industry. We do not maintain key person insurance on any of our employees, officers, or directors.

Changes in environmental regulations and enforcement policies could subject us to additional liability and adversely affect our ability to continue certain operations.

We cannot predict the extent to which our operations may be affected by future governmental enforcement policies as applied to existing laws, by changes to current environmental laws and regulations, or by the enactment of new environmental laws and regulations. Any predictions regarding possible liability under such laws are complicated further by current environmental laws which provide that we could be liable, jointly and severally, for certain activities of third parties over whom we have limited or no control.

The refusal to accept our waste for disposal by, or a closure of, the end disposal site that our Nuclear Segment utilizes to dispose of its waste could subject us to significant risk and limit our operations.

Our Nuclear Segment has limited options available for disposal of its waste. If this disposal site ceases to accept waste or closes for any reason or refuses to accept the waste of our Nuclear Segment, for any reason, we could have nowhere to dispose of our nuclear waste or have significantly increased costs from disposal alternatives. With nowhere to dispose of our nuclear waste, we would be subject to significant risk from the implications of storing the waste on our site, and we would have to limit our operations to accept only waste that we can dispose of.

Our businesses subject us to substantial potential environmental liability.

Our business of rendering services in connection with management of waste, including certain types of hazardous waste, low-level radioactive waste, and mixed waste (waste containing both hazardous and low-level radioactive waste), subjects us to risks of liability for damages. Such liability could involve, without limitation:

claims for clean-up costs, personal injury or damage to the environment in cases in which we are held responsible for the release of hazardous or radioactive materials; and

claims of employees, customers, or third parties for personal injury or property damage occurring in the course of our operations; and

claims alleging negligence or professional errors or omissions in the planning or performance of our services.

Our operations are subject to numerous environmental laws and regulations. We have in the past, and could in the future, be subject to substantial fines, penalties, and sanctions for violations of environmental laws and substantial expenditures as a responsible party for the cost of remediating any property which may be contaminated by hazardous substances generated by us and disposed at such property, or transported by us to a site selected by us, including properties we own or lease.

As our operations expand, we may be subject to increased litigation, which could have a negative impact on our future financial results.

Our operations are highly regulated and we are subject to numerous laws and regulations regarding procedures for waste treatment, storage, recycling, transportation, and disposal activities, all of which may provide the basis for litigation against us. In recent years, the waste treatment industry has experienced a significant increase in so-called “toxic-tort” litigation as those injured by contamination seek to recover for personal injuries or property damage. We believe that, as our operations and activities expand, there will be a similar increase in the potential for litigation alleging that we have violated environmental laws or regulations or are responsible for contamination or pollution caused by our normal operations, negligence or other misconduct, or for accidents, which occur in the course of our business activities. Such litigation, if significant and not adequately insured against, could adversely affect our financial condition and our ability to fund our operations. Protracted litigation would likely cause us to spend significant amounts of our time, effort, and money. This could prevent our management from focusing on our operations and expansion.

Our operations are subject to seasonal factors, which cause our revenues to fluctuate.

We have historically experienced reduced revenues and losses during the first and fourth quarters of our fiscal years due to a seasonal slowdown in operations from poor weather conditions, overall reduced activities during these periods resulting from holiday periods, and finalization of government budgets during the fourth quarter of each year. During our second and third fiscal quarters there has historically been an increase in revenues and operating profits. If we do not continue to have increased revenues and profitability during the second and third fiscal quarters, this will have a material adverse effect on our results of operations and liquidity.

If environmental regulation or enforcement is relaxed, the demand for our services will decrease.

The demand for our services is substantially dependent upon the public's concern with, and the continuation and proliferation of, the laws and regulations governing the treatment, storage, recycling, and disposal of hazardous, non-hazardous, and low-level radioactive waste. A decrease in the level of public concern, the repeal or modification of these laws, or any significant relaxation of regulations relating to the treatment, storage, recycling, and disposal of hazardous waste and low-level radioactive waste would significantly reduce the demand for our services and could have a material adverse effect on our operations and financial condition. We are not aware of any current federal or state government or agency efforts in which a moratorium or limitation has been, or will be, placed upon the creation of new hazardous or radioactive waste regulations that would have a material adverse effect on us; however, no assurance can be made that such a moratorium or limitation will not be implemented in the future.

We and our customers operate in a politically sensitive environment, and the public perception of nuclear power and radioactive materials can affect our customers and us.

We and our customers operate in a politically sensitive environment. Opposition by third parties to particular projects can limit the handling and disposal of radioactive materials. Adverse public reaction to developments in the disposal of radioactive materials, including any high profile incident involving the discharge of radioactive materials, could directly affect our customers and indirectly affect our business. Adverse public reaction also could lead to increased regulation or outright prohibition, limitations on the activities of our customers, more onerous operating requirements or other conditions that could have a material adverse impact on our customers’ and our business.

We may not be successful in winning new business mandates from our government and commercial customers.

We must be successful in winning mandates from our government and commercial customers to replace revenues from projects that are nearing completion and to increase our revenues. Our business and operating results can be adversely affected by the size and timing of a single material contract.

The elimination or any modification of the Price-Anderson Acts indemnification authority could have adverse consequences for our business.

The Atomic Energy Act of 1954, as amended, or the AEA, comprehensively regulates the manufacture, use, and storage of radioactive materials. The Price-Anderson Act supports the nuclear services industry by offering broad indemnification to DOE contractors for liabilities arising out of nuclear incidents at DOE nuclear facilities. That indemnification protects DOE prime contractor, but also similar companies that work under contract or subcontract for a DOE prime contract or transporting radioactive material to or from a site. The indemnification authority of the DOE under the Price-Anderson Act was extended through 2025 by the Energy Policy Act of 2005.

The Price-Anderson Act’s indemnification provisions generally do not apply to our processing of radioactive waste at governmental facilities, and do not apply to liabilities that we might incur while performing services as a contractor for the DOE and the nuclear energy industry. If an incident or evacuation is not covered under Price-Anderson Act indemnification, we could be held liable for damages, regardless of fault, which could have an adverse effect on our results of operations and financial condition. If such indemnification authority is not applicable in the future, our business could be adversely affected if the owners and operators of new facilities fail to retain our services in the absence of commercial adequate insurance and indemnification.

We are engaged in highly competitive businesses and typically must bid against other competitors to obtain major contracts.

We are engaged in highly competitive business in which most of our government contracts and some of our commercial contracts are awarded through competitive bidding processes. We compete with national and regional firms with nuclear services practices, as well as small or local contractors. Some of our competitors have greater financial and other resources than we do, which can give them a competitive advantage. In addition, even if we are qualified to work on a new government contract, we might not be awarded the contract because of existing government policies designed to protect certain types of businesses and underrepresented minority contractors. Competition also places downward pressure on our contract prices and profit margins. Intense competition is expected to continue for nuclear service contracts. If we are unable to meet these competitive challenges, we could lose market share and experience on overall reduction in our profits.

Our failure to maintain our safety record could have an adverse effect on our business.

Our safety record is critical to our reputation. In addition, many of our government and commercial customers require that we maintain certain specified safety record guidelines to be eligible to bid for contracts with these customers. Furthermore, contract terms may provide for automatic termination in the event that our safety record fails to adhere to agreed-upon guidelines during performance of the contract. As a result, our failure to maintain our safety record could have a material adverse effect on our business, financial condition and results of operations.

We continue to have material weaknesses in our Internal Control over Financial Reporting (“ICFR”).

During our evaluation of our ICFR, we noted that the monitoring of invoicing process controls and the corresponding transportation and disposal process controls at our Industrial Segment subsidiaries were ineffective and were not being applied consistently. In addition, we noted that the monitoring of quote to invoicing control was ineffective at certain of our Nuclear Segment subsidiaries. These deficiencies resulted in material weaknesses to our ICFR, and could result in sales being priced and invoiced at amounts which were not approved by the customer, or the appropriate level of management, and recognition of revenue in incorrect financial reporting period. These deficiencies have resulted in our disclosure that our ICFR was ineffective as of the end of 2008 and 2007. Although these material weaknesses did not result in a material adjustment to our quarterly or annual financial statements, if we are unable to remediate these material weaknesses, there is a reasonable possibility that a misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

We may be unable to utilize loss carryforwards in the future.

We have approximately $26,589,000 in net operating loss carryforwards which will expire from 2009 to 2028 if not used against future federal income tax liabilities. Our net loss carryforwards are subject to various limitations. Our ability to use the net loss carryforwards depends on whether we are able to generate sufficient income in the future years. Further, our net loss carryforwards have not been audited or approved by the Internal Revenue Service.

Risks Relating to our Intellectual Property

If we cannot maintain our governmental permits or cannot obtain required permits, we may not be able to continue or expand our operations.

We are a waste management company. Our business is subject to extensive, evolving, and increasingly stringent federal, state, and local environmental laws and regulations. Such federal, state, and local environmental laws and regulations govern our activities regarding the treatment, storage, recycling, disposal, and transportation of hazardous and non-hazardous waste and low-level radioactive waste. We must obtain and maintain permits or licenses to conduct these activities in compliance with such laws and regulations. Failure to obtain and maintain the required permits or licenses would have a material adverse effect on our operations and financial condition. If any of our facilities are unable to maintain currently held permits or licenses or obtain any additional permits or licenses which may be required to conduct its operations, we may not be able to continue those operations at these facilities, which could have a material adverse effect on us.

We believe our proprietary technology is important to us.

We believe that it is important that we maintain our proprietary technologies. There can be no assurance that the steps taken by us to protect our proprietary technologies will be adequate to prevent misappropriation of these technologies by third parties. Misappropriation of our proprietary technology could have an adverse effect on our operations and financial condition. Changes to current environmental laws and regulations also could limit the use of our proprietary technology.

Risks Relating to our Financial Position and Need for Financing

Breach of financial covenants in existing credit facility could result in a default, triggering repayment of outstanding debt under the credit facility.

Our credit facility with our bank contains financial covenants. A breach of any of these covenants could result in a default under our credit facility triggering our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. In the past, none of our covenants have been restrictive to our operations. If we fail to meet our loan covenants in the future and our lender does not waive the non-compliance or revise our covenant so that we are in compliance, our lender could accelerate the repayment of borrowings under our credit facility. In the event that our lender accelerates the payment of our borrowing, we may not have sufficient liquidity to repay our debt under our credit facility and other indebtedness.

Our amount of debt and floating rates of interest could adversely affect our operations.

At December 31, 2008, our aggregate consolidated debt was approximately $16,203,000. If our floating rates of interest experienced an upward increase of 1%, our debt service would increase by approximately $162,000 annually. Our secured revolving credit facility (the “Credit Facility”) provides for an aggregate commitment of $25,000,000, consisting of an $18,000,000 revolving line of credit and a term loan of $7,000,000. The maximum we can borrow under the revolving part of the Credit Facility is based on a percentage of the amount of our eligible receivables outstanding at any one time. As of December 31, 2008, we had borrowings under the revolving part of our Credit Facility of $6,500,000 and borrowing availability of up to an additional $5,400,000 based on our outstanding eligible receivables. A lack of operating results could have material adverse consequences on our ability to operate our business. Our ability to make principal and interest payments, or to refinance indebtedness, will depend on both our and our subsidiaries' future operating performance and cash flow. Prevailing economic conditions, interest rate levels, and financial, competitive, business, and other factors affect us. Many of these factors are beyond our control.

Risks Relating to an Investment in our Common Stock

Issuance of substantial amounts of our common stock could depress our stock price.

Any sales of substantial amounts of our Common Stock in the public market could cause an adverse effect on the market price of our Common Stock and could impair our ability to raise capital through the sale of additional equity securities. The issuance of our Common Stock will result in the dilution in the percentage membership interest of our stockholders and the dilution in ownership value. As of March 31, 2009, we had 53,985,119 shares of Common Stock outstanding.

In addition, as of March 31, 2009, we had outstanding options to purchase 3,558,347 shares of common stock at exercise prices from $1.22 to $2.98 per share. Further, we have adopted a preferred share rights plan, and if such is triggered, could result in the issuance of a substantial amount of our common stock. The existence of this quantity of rights to purchase our common stock could result in a significant dilution in the percentage ownership interest of our stockholders and the dilution in ownership value. Future sales of the shares issuable could also depress the market price of our common stock.

We do not intend to pay dividends on our common stock in the foreseeable future.

Since our inception, we have not paid cash dividends on our common stock, and we do not anticipate paying any cash dividends in the foreseeable future. Our Credit Facility prohibits us from paying cash dividends on our common stock.

The price of our common stock may fluctuate significantly, which may make it difficult for you to resell our common stock when you want or at prices you find attractive.

The price of our common stock on the Nasdaq Capital Markets constantly changes. We expect that the market price of our common stock will continue to fluctuate. This may make it difficult for you to resell the common stock when you want or at prices you find attractive.

Future issuance or potential issuance of our common stock could adversely affect the price of our common stock, our ability to raise funds in new stock offerings and dilute your percentage interest in our common stock.

Future sales of substantial amounts of our common stock in the public market, or the perception that such sales could occur, could adversely affect prevailing trading prices of our common stock, and impair our ability to raise capital through future offerings of equity. No prediction can be made as to the effect, if any, that future issuances or sales of shares of common stock or the availability of shares of common stock for future issuance, will have on the trading price of our common stock. Such future issuances could also significantly reduce the percentage ownership and dilute the ownership value of our existing common stockholders.

Delaware law, certain of our charter provisions, our stock option plans and outstanding warrants and our preferred stock may inhibit a change of control under circumstances that could give you an opportunity to realize a premium over prevailing market prices.

We are a Delaware corporation governed, in part, by the provisions of Section 203 of the General Corporation Law of Delaware, an anti-takeover law. In general, Section 203 prohibits a Delaware public corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. As a result of Section 203, potential acquirers may be discouraged from attempting to effect acquisition transactions with us, thereby possibly depriving our security holders of certain opportunities to sell, or otherwise dispose of, such securities at above-market prices pursuant to such transactions. Further, certain of our option plans provide for the immediate acceleration of, and removal of restrictions from, options and other awards under such plans upon a “change of control” (as defined in the respective plans). Such provisions may also have the result of discouraging acquisition of us.

We have authorized and unissued 17,456,534 (which include outstanding options to purchase 3,558,347 shares of our Common Stock) shares of Common Stock and 2,000,000 shares of Preferred Stock as of March 31, 2009 (which includes 600,000 shares of our Preferred Stock reserved for issuance under our preferred share rights plan). These unissued shares could be used by our management to make it more difficult, and thereby discourage an attempt to acquire control of us.

Our Preferred Share Rights Plan may adversely affect our stockholders.

In May 2008, we adopted a preferred share rights plan (the “Rights Plan”), designed to ensure that all of our stockholders receive fair and equal treatment in the event of a proposed takeover or abusive tender offer. However, the Rights Plan may also have the effect of deterring, delaying, or preventing a change in control that might otherwise be in the best interests of our stockholders.

In general, under the terms of the Rights Plan, subject to certain limited exceptions, if a person or group acquires 20% or more of our common stock or a tender offer or exchange offer for 20% or more of our common stock is announced or commenced, our other stockholders may receive upon exercise of the rights (the “Rights”) issued under the Rights Plan the number of shares our common stock or of one-one hundredths of a share of our Series A Junior Participating Preferred Stock, par value $.001 per share, having a value equal to two times the purchase price of the Right. In addition, if we are acquired in a merger or other business combination transaction in which we are not the survivor or more than 50% of our assets or earning power is sold or transferred, then each holder of a Right (other than the acquirer) will thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the purchase price of the Right. The purchase price of each Right is $13, subject to adjustment.

The Rights will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors. The Rights may be redeemed by us at $0.001 per Right at any time before any person or group acquires 20% or more of our outstanding common stock. The rights should not interfere with any merger or other business combination approved by our board of directors. The Rights expire on May 2, 2018.

Resale of shares offered by this prospectus could adversely affect the market price of our common stock and our ability to raise additional equity capital.

The sale, or availability for sale, of common stock in the public market pursuant to this prospectus may adversely affect the prevailing market price of our common stock and may impair our ability to raise additional capital by selling equity or equity-related securities. This prospectus includes 5,000,000 shares that will be available for resale (assuming the issuance from time to time of all of the common stock included in this offering). The resale of a substantial number of shares of our common stock in the public market pursuant to this offering, and afterwards, could adversely affect the market price for our common stock and make it more difficult for you to sell our shares at times and prices that you feel are appropriate.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained within this prospectus and the documents incorporated into this prospectus by reference may be deemed “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (collectively, the “Private Securities Litigation Reform Act of 1995”). All statements in this prospectus and the documents incorporated into this prospectus by reference other than a statement of historical fact are forward-looking statements that are subject to known and unknown risks, uncertainties and other factors, which could cause actual results and performance of the Company to differ materially from such statements. The words “believe,” “expect,” “anticipate,” “intend,” “will,” “may,” and similar expressions identify forward-looking statements. Forward-looking statements include, without limitation, the statements listed under “Special Note Regarding Forward-Looking Statements” in our 2008 Form 10-K, all of which are incorporated by reference herein, as well as those forward-looking statements identified in our other SEC filings incorporated by reference in this prospectus.

While we believe the expectations reflected in such forward-looking statements are reasonable, we can give no assurance such expectations will prove to be correct. There are a variety of factors which could cause future outcomes to differ materially from those described in this report, including, but not limited to:

·	general economic conditions;

·	material reduction in revenues;

·	inability to collect in a timely manner a material amount of receivables;

·	increased competitive pressures;

·	the ability to maintain and obtain required permits and approvals to conduct operations;

·	the ability to develop new and existing technologies in the conduct of operations;

·	ability to retain or renew certain required permits;

·	discovery of additional contamination or expanded contamination at any of the sites or facilities leased or owned by us or our subsidiaries which would result in a material increase in remediation expenditures;

·	changes in federal, state and local laws and regulations, especially environmental laws and regulations, or in interpretation of such;

·	potential increases in equipment, maintenance, operating or labor costs;

·	management retention and development;

·	financial valuation of intangible assets is substantially more/less than expected;

·	the requirement to use internally generated funds for purposes not presently anticipated;

·	the inability to maintain the listing of our Common Stock on the NASDAQ;

·	terminations of contracts with federal agencies or subcontracts involving federal agencies, or reduction in amount of waste delivered to us under these contracts or subcontracts;

·	disposal expense accrual could prove to be inadequate in the event the waste requires retreatment; and

other factors described under “Risk Factors” in this prospectus and in the other documents we have filed with the SEC and that are incorporated herein by reference, including the factors described under “Business,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in our annual report on Form 10-K for the fiscal year ended December 31, 2008 and that may be discussed from time to time in other reports filed with the SEC subsequent to the registration statement of which this prospectus is a part.

Any forward-looking statement speaks only as to the date on which that statement is made. We undertake no obligation to update publicly any forward-looking statement, whether as a result of new information, future events or otherwise.

USE OF PROCEEDS

Unless otherwise indicated in the prospectus supplement, we intend to use the net proceeds from the sale of the securities offered by this prospectus for general corporate purposes and working capital requirements, which may include the repayment of indebtedness. Under the terms of our existing Credit Facility, we may also use a portion of the net proceeds to fund possible investments in and acquisitions of complimentary businesses, partnerships, minority investments, products or technologies with the consent of our Credit Facility lender. Currently, there are no commitments or agreements regarding such acquisitions or investments that are material. Pending their ultimate use, we intend to invest the net proceeds in money market funds, commercial paper and governmental and non-governmental debt securities with maturities of up to three years. The terms of our existing Credit Facility require us to maintain such investments with our Credit Facility lender or its affiliates, which investments serve as additional collateral under the Credit Facility.

PLAN OF DISTRIBUTION

We may sell the securities:

through one or more underwriters or dealers,

directly to purchasers,

through agents, or

through a combination of any of these methods of sale.

We may distribute the securities:

from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time,

at market prices prevailing at the times of sale,

at prices related to such prevailing market prices, or

at negotiated prices.

We will describe the method of distribution of the securities in the applicable prospectus supplement.

We may determine the price or other terms of the securities offered under this prospectus by use of an electronic auction. We will describe how any auction will determine the price or any other terms, how potential investors may participate in the auction and the nature of the obligations of the underwriter, dealer or agent in the applicable prospectus supplement.

If underwriters are used in the sale, they will acquire the common stock for their own account and may resell the stock from time to time in one or more transactions at a fixed public offering price. The obligations of the underwriters to purchase the common stock will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the common stock to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us or our purchasers (as their agents in connection with the sale of securities). These underwriters, dealers or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions, or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. Each prospectus supplement will identify any such underwriter, dealer or agent, and describe any compensation received by them from us. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Underwriters, dealers and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments made by the underwriters, dealers or agents, under agreements between us and the underwriters, dealers and agents.

We may grant underwriters who participate in the distribution of securities an option to purchase additional securities to cover over-allotments, if any, in connection with the distribution.

Underwriters or agents and their associates may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In connection with the offering of our common stock, certain persons participating in such offering may engage in transactions that stabilize, maintain or otherwise affect the market price, including over-allotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the common stock in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the common stock originally sold by the dealer is purchased in a covering transaction to cover short positions. Those activities may cause the price of the common stock to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters who are qualified market makers on the NASDAQ Capital Markets may engage in passive market making transactions in the common stock on the NASDAQ Capital Global Markets in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

To the extent required, this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution.

DESCRIPTION OF COMMON STOCK

Our certificate of incorporation authorizes us to issue up to 75,000,000 shares of common stock, $0.001 par value. As of April 3, 2009, there were 54,019,324 shares of our common stock issued and outstanding.

The holders of shares of our common stock are entitled to one vote per share on all matters to be voted on by stockholders. Common stock holders are entitled to receive dividends declared by the board of directors out of funds legally available for the payment of dividends, subject to the rights, if any, of preferred stock holders. However, we have never paid a dividend and we do not anticipate paying a dividend in the foreseeable future. Our current secured credit facility prohibits us from paying cash dividends on our common stock. Upon any liquidation, dissolution or winding up of our business, the holders of common stock are entitled to share equally in all assets available for distribution after payment of all liabilities and provision for liquidation preference of shares of preferred stock then outstanding. The holders of common stock have no preemptive rights and no rights to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of common stock are fully paid and nonassessable.

Each share of our common stock includes an attached Right arising under and subject to the terms described in, the Rights Agreement, dated May 2, 2008 between us and Continental Stock Transfer & Trust Company, as rights agent. The terms of such Rights are summarized in “Rights Attaching to Our Common Stock” below.

The transfer agent and registrar for the common stock is Continental Stock Transfer & Trust Company 17 Battery Place, Floor 8, New York, New York 10004-1123.

RIGHTS ATTACHING TO OUR COMMON STOCK

On May 2, 2008, our Board of Directors declared a dividend distribution of one Right for each outstanding share of our common stock to our stockholders of record on May 12, 2008 (the “Record Date”). The Rights Agreement (as defined below) also contemplates the issuance of one Right for each share of common stock which is issued by the Company between the Record Date and the Distribution Date (or earlier redemption or termination of the Rights). The Rights are subject to the terms and conditions of the Rights Agreement, a copy of which is attached as Exhibit 4.1 to the Current Report on Form 8-K filed with the SEC on May 8, 2008. A copy of the Rights Agreement is also available upon written request to us. You are advised to review the entire Rights Agreement prior to making any investment decision.

Each Right entitles the registered holder to purchase from us one one-hundredth of a share of our Series A Junior Participating Preferred Stock, par value $.001 per share (the “Preferred Shares”) at a purchase price of $13.00 per one-one hundredth of a Preferred Share (the “Purchase Price”), subject to adjustment.

Until the earlier to occur of (a) 10 days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) have acquired beneficial ownership of 20% or more of our outstanding common stock (except pursuant to a Permitted Offer, as defined below, or persons excluded from being an Acquiring Person under the Rights Agreement) or (b) 10 business days (or such later date as may be determined by action of the Board of Directors prior to such time as any person becomes an Acquiring Person) following the commencement of, or announcement of an intention (which intention to commence remains in effect for 5 business days after such announcement) to make a tender offer or exchange offer, the consummation of which would result in a person or group becoming an Acquiring Person of 20% or more of our common stock (the earlier of such dates being called the “Distribution Date”), the Rights will be evidenced with respect to any of the common stock certificates outstanding and no separate Rights Certificates will be distributed.

Excluded from being an Acquiring Person under the Rights Agreement are the following (collectively, the “Excluded Persons”):

the Company;

any of our subsidiaries;

any employee benefit plan of us or our subsidiaries;

any entity holding common stock for or pursuant to the employee benefit plan o us or our subsidiaries;

any Person who becomes the beneficial owner of 20% or more of the common stock solely as a result of the acquisition of common stock by us, unless such Person shall, after such share purchases by us, become the beneficial owner of additional shares of common stock constituting 1% or more of the then outstanding shares of common stock; and

any person whom our Board of Directors determines in good-faith has acquired 20% or more of the common stock inadvertently and such person divests, within 10 business days after such determination, a sufficient number of shares of common stock to no longer beneficially own 20% of the common stock.

The Rights Agreement provides that, until the Distribution Date (or earlier redemption or expiration of the Rights):

the Rights will be transferred with and only with our common stock;

new common stock certificates issued after the Record Date, upon transfer or new issuance of common stock by us will contain a notation incorporating the Rights Agreement by reference; and

the surrender for transfer of any certificates for common stock, even without such notation (or a copy of a summary of rights) being attached thereto, will also constitute the transfer of Rights associated with the common stock represented by such certificate.

As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (“Right Certificates”) will be mailed to the holders of record of the common stock as of the close of business on the Distribution Date and such separate Right Certificates alone will evidence the Rights.

The Rights are not exercisable until the Distribution Date. The Rights will expire on May 2, 2018 (the “Final Expiration Date”), unless the Final Expiration Date is extended or unless the Rights are earlier redeemed by us, in each case, as described below.

In the event that any person becomes an Acquiring Person (except pursuant to a tender or exchange offer which is for all outstanding shares of common stock at a price and on terms which a majority of certain members of the Board of Directors determines to be adequate and in our best interests, our stockholders and other relevant constituencies, other than the Acquiring Person, its affiliates and associates (a “Permitted Offer”)), each holder of a Right (except Rights which have been voided as set forth below) will thereafter have the right (the “Flip-In Rights”) to receive upon exercise the number of shares of common stock or of one-one hundredths of a share of Preferred Shares (or, in certain circumstances, other of our securities) having a value (on the date such person became an Acquiring Person) equal to two times the Purchase Price of the Right.

In the event that at any time (a) we are acquired in a merger or other business combination transaction in which we are not the survivor, (b) a merger or other business combination with us in which we are the survivor and, in connection with such transaction, all or part of the shares of common stock shall be changed for stock or other securities of any other person (or us) or (c) more than 50% of our assets or earning power is sold or transferred, then each holder of a Right (except Rights which have been voided as set forth below) shall thereafter have the right (the “Flip-Over Right”) to receive, upon exercise, common stock of the acquiring company having a value equal to two times the Purchase Price of the Right. The Flip-Over Right is not applicable to transactions described in (a) and (b) of this paragraph if (i) such transaction is consummated with a person who acquired common stock pursuant to a Permitted Offer; (ii) the price per share of common stock offered in such transaction is not less than the price per share of common stock paid to all holders of common stock purchased pursuant to the Permitted Offer, and (iii) the form of consideration offered in such transaction is the same as the form of consideration paid pursuant to the Permitted Offer.

The Purchase Price payable, and the number of Preferred Shares, common stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution:

in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Shares;

upon the grant to holders of the Preferred Shares of certain rights or warrants to subscribed for or purchase Preferred Shares at a price, or securities convertible into Preferred Shares with a conversion price, less than the then current market price of the Preferred Shares; or

upon the distribution to holders of the Preferred Shares of evidences of indebtedness or assets (excluding regular periodic cash dividends paid out of earnings or retained earnings or dividends payable in Preferred Shares) or of subscription rights or warrants (other than those referred to above).

The number of outstanding Rights and the number of one one-hundredths of a Preferred Share issuable upon exercise of each Right are also subject to adjustment in the event of a stock split of the common stock or a stock dividend on the common stock payable in common stock or subdivisions, consolidations or combinations of the common stock occurring, in any such case, prior to the Distribution Date.

Any Rights that are beneficially owned by (a) any Acquiring Person (or any affiliate or associate of such Acquiring Person), (b) a transferee of an Acquiring Person (or any affiliate or associate thereof) who becomes a transferee after the Acquiring Person becomes such, or (c) under certain conditions, a transferee of any Acquiring Person (or any affiliate or associate thereof) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such, shall be null and void and no holder of such Rights shall thereafter have rights to exercise such Rights.

At any time after a person becomes an Acquiring Person and prior to the acquisition by such Person (or affiliate or associate of an Acquiring Person) of 50% or more of the outstanding common stock, our Board of Directors may exchange the Rights (other than Rights owned by such Acquiring Person which have become void), in whole or in part, at an exchange ratio of one share of common stock, or one-one hundredth of a Preferred Share (or of a share of a class or series of the our preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment). Upon our Board of Directors ordering the exchange, the right to exercise the Right shall terminate and the only right thereafter shall be to receive the shares in accordance with the exchange.

With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price. No fractional Preferred Shares will be issued (other than fractions which are integral multiples of one one-hundredth of a Preferred Share, which may, at the election of the Company, be evidenced by depositary receipts) and in lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Shares on the last trading day prior to the date of exercise.

At any time prior to the earlier of the Distribution Date or Final Expiration Date, our Board of Directors may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (the “Redemption Price”), adjusted to reflect any stock split, stock dividend or similar transaction, and payable, at our option, either in cash, shares of common stock, or any other form of consideration deemed appropriate by our Board. The redemption of the rights may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holder of Rights will be to receive the Redemption Price.

The terms of the Rights Agreement and the Rights may be amended by us without the consent of the holders of the Rights, in order to cure any ambiguity, to correct or supplement any provision contained therein which may be defective or inconsistent with any other provisions contained therein, or to make any other changes or amendments to the provisions contained therein which the Company may deem necessary or desirable, except that from and after such time as any person becomes an Acquiring Person no such amendment may adversely affect the interests of the holders of the Rights (other than the Acquiring Person or any affiliate or associate of the Acquiring Person). No amendment to the Rights Agreement or the Rights shall be made which changes the redemption price or the number of Preferred Shares or shares of common stock for which a Right is exercisable or exchangeable.

Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends.
