THE COMMON STOCK WE MAY OFFER
We may offer up to an aggregate of 5,000,000 shares of common stock in one or more offerings.  A prospectus supplement, which we will provide to you each time we offer securities, will describe the specific amounts, prices and terms of these securities.
We may sell the common stock to or through underwriters, dealers or agents or directly to purchasers.  We and our agents reserve the sole right to accept and to reject in whole or in part any proposed purchase of securities.  Each prospectus supplement will set forth the names of any underwriters, dealers or agents involved in the sale of the common stock described in that prospectus supplement and any applicable fee, commission or discount arrangements with them.
Common stock holders are entitled to receive dividends declared by our board of directors out of funds legally available for the payment of dividends, subject to 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.  Each holder of common stock is entitled to one vote per share.  The holders of common stock have no preemptive rights or cumulative voting rights.  A prospectus supplement will describe the specific amounts, prices and terms of any common stock to be issued.

RISK FACTORS Investing

An investment in our securities involves a high degree of risk.  BeforeYou should carefully consider the risks described below before making an investment decision, youas 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 carefully consideralso refer to the risk factors set forthother information in this prospectus and any accompanying prospectus supplement delivered withincorporated by reference into this prospectus as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement and the additional information in the other reports we file with the Securities and Exchange Commission ("SEC"(“SEC”). OUR SUBSTANTIAL AMOUNT OF DEBT COULD ADVERSELY AFFECT OUR OPERATIONS. We have a substantial amount of debt. At March 31, 2004,
2

The risks and uncertainties described below are not the only risks and uncertainties we face.  Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our aggregate consolidated debt was approximately $20.9 million.business operations.  If our floating rates of interest experienced an upward increase of 1%, our debt service would increase by approximately $209,000 annually. Our secured revolving credit facility (the "Credit Facility") provides for an aggregate commitment of $25 million, consisting of an $18 million revolving line of credit and a term loan of $7 million. The maximum we can borrow under the revolving partany of the Credit Facility is based on a percentage of the amount of our eligible receivables outstanding at any one time. The Credit Facility is due December, 2005. Although we used a substantial portion of the net proceeds received from a recently completed private placement (see "Recent Developments - Private Placement") to reduce our indebtedness under the revolving part of the Credit Facility, we intend to continue to borrow under that facility from time to time, and this reduction did not reduce the amount we can borrow under the Credit Facility. As of March 31, 2004, we had borrowings under our revolving part of our Credit Facility of $1.7 million and borrowing availability of up to an additional $11.4 million based on our then outstanding eligible receivables. Our high leverage could have material adverse consequences on our ability to operatefollowing risks actually occur, our business, including the following: o it may make it difficult for us to satisfy our obligations and contractual and commercial commitments o our ability to obtain additional financing in the future for refinancing indebtedness, acquisitions, working capital, capital expenditures or other purposes may be impaired; o funds available to us for ourresults of operations and general corporate purposes or for capital expenditures will be reduced because a substantial portion of our consolidated cash flow from operations will be dedicated to the payment of the principal and interest on our indebtedness; o we may be more highly leveraged than certain of our competitors, which may place us at a competitive disadvantage; o we may be more vulnerable to a downturn in general economic conditions; o certain of the borrowings under our debt agreements have floating rates of interest, which cause us to be vulnerable to increases in interest rates; and 2 o we must use a substantial portion of our cash flow from operations to pay interest on our indebtedness, which reduces the funds available to us for other purposes. 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. THE DOCUMENTS GOVERNING OUR INDEBTEDNESS RESTRICT OUR ABILITY TO ENGAGE IN CERTAIN BUSINESS TRANSACTIONS. The terms of the Credit Facility restrict our ability and the ability of our subsidiaries, without the lender's approval, to, among other things: o incur or guarantee additional indebtedness; o pay cash dividends on, redeem or repurchase capital stock; o make certain investments; o incur or permit to exist liens; o make material changes in the nature or conduct of our business; o merge or consolidate with or acquire substantially all of the stock or assets of other companies; and o transfer or sell assets. The Credit Facility also requires that we meet specified financial ratios and financial condition tests. Our ability to make additional borrowings undercould suffer. In that event, the Credit Facility depends upon satisfaction of these covenants. Our ability to meet these covenants and requirements may be affected by events beyond our control. Our failure to comply with obligations under the Credit Facility could result in an event of default under the facility. A default, if not cured or waived, could permit acceleration of our indebtedness. We cannot be certain that we will be able to remedy any default. If our indebtedness is accelerated, we cannot be certain that we will have funds available to pay the accelerated indebtedness or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all. THE CONVERSION OF OUR CONVERTIBLE PREFERRED STOCK AND EXERCISE OF OUR OUTSTANDING WARRANTS AND OPTIONS COULD CAUSE THE MARKET PRICE OF OUR COMMON STOCK TO FALL AND MAY HAVE DILUTION AND OTHER EFFECTS ON OUR EXISTING STOCKHOLDERS. The conversion of our outstanding Series 17 Class Q Convertible Preferred Stock, par value $.001 per share (the "Series 17 Preferred") could result in the issuance of up to 1,666,667 shares of common stock at a conversiontrading price of $1.50 per share of common stock, subject to adjustment pursuant to certain anti-dilution provisions. The exercise of our outstanding warrants and options into common stock could result in the issuance of up to approximately 12,980,493 shares and 3,139,950 shares, respectfully (assuming that all options and warrants are currently exercisable). The exercise prices of the outstanding warrants and options range from $1.00 per share to $3.25 per share, subject to adjustment pursuant to certain anti-dilution provisions. Consequently, upon such issuances, our stockholders could experience a significant dilution of their investment. Dilution of our common stock could decline, and you may potentially have a material adverse impact on our earnings per share and could, among other things, depress the pricelose all or part of your investment in our common stock.  This result could detrimentally affectThe risks discussed below also include forward-looking statements and our abilityactual results may differ substantially from those discussed in these forward-looking statements.

Risks Relating to raise additional equity capital. The conversionour 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 outstanding Series 17 Preferredpermitted 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 the exercise of all of our outstanding warrants and options could result in us having outstanding a total of 59,214,835 shares of common stock, assuming all outstanding warrants and options are currently exercisable and subject to adjustment pursuant to certain anti-dilution provisions. Such issuances would significantly reduce the percentage ownership of our existing and future common stockholders. Many of the beneficial holders of our convertible preferred stock and the holders of many of our outstanding warrants and options may immediately sell the full amount of common stock received upon conversion of the convertible preferred stock and exercise of the warrants and options, as applicable, as those shares of common stock are subject to effective registration statements that are currently in effect. As these shares are sold, the price of the common stock may decrease. 3 CAPITAL BANK'S INVESTORS BENEFICIALLY OWN A SIGNIFICANT NUMBER OF OUR OUTSTANDING SHARES, HAVE THE RIGHT TO ACQUIRE ADDITIONAL SHARES, AND HAVE THE ABILITY TO RESELL SUCH SHARES, WHICH MAY ADVERSELY AFFECT OUR ABILITY TO RAISE ADDITIONAL FUNDS AND TO UNDERTAKE CERTAIN TRANSACTIONS. As of April 22, 2004, Capital Bank-Grawe Gruppe AG ("Capital Bank"), owned of record, as agent for certain of its investors, 7,246,045 shares of our common stock or approximately 17.5% of the outstanding shares of common stock, and had the right to acquire an additional 4,334,805 shares of common stock pursuant to the convertible preferred stock and warrants held in Capital Bank's name, as agent for certain investors. If Capital Bank acquires all of the shares issuable pursuant to such preferred stock and warrants, Capital Bank would own of record 11,580,850 shares of common stock, representing 25.3% of our then issued and outstanding common stock, assuming we issue no other shares of common stock and Capital Bank does not dispose of any shares. We receive proceeds fromPCB wastes under a permit issued by the exercise for cash of the warrants held by Capital Bank's investors, but we will not receive any proceeds from the resale of these shares by Capital Bank's investors. A substantial amount of the shares beneficially owned by Capital Bank's investors are registered for resale. To the extent that Capital Bank's investors sell these shares at times when we are attempting to raise additional capital, our ability to raise these additional funds may be adversely impacted. We are not aware of any agreement or understanding among Capital Bank's investors to act as a group (as defined in Rule 13d-5(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). However, if Capital Bank's investors agree to act as a group or otherwise to act in concertEPA on November 26, 2008.  The AIG subsidiary also provides other operating insurance policies for the purpose of voting on matters subject to stockholder vote,Company and our management could be greatly impacted. For instance, this investor group could instruct Capital Bank to vote for or againstsubsidiaries.  In the approvalevent of a merger or other proposal requiring stockholder approval. As a result, the abilityfailure of our other stockholders to influence our management and policiesAIG, this could be limited, and their ability to realize opportunities to sell some or all of their stock at prices that represent a premium over market prices could be lost. THE ISSUANCE OF ADDITIONAL SHARES OF OUR COMMON STOCK MAY ALSO RESULT IN A CHANGE IN CONTROL. The issuance of additional shares of our common stock upon conversion of the Series 17 Preferred and exercise of our currently outstanding warrants could result in a substantial number of shares being held by one or more groups acting in concert. In that event, such group or groups may have the ability to cause a change in control under our Credit Agreement. Our Credit Facility provides that a change of control will occur if (a) Dr. Louis F. Centofanti, our Chairman, President, and Chief Executive Officer, or Richard T. Kelecy, our Chief Financial Officer, ceases to serve as a senior executive officer in substantially the same capacity as served on the date of the Credit Facility or (b) the persons who were members of our Board on the closing of the Credit Facility cease to constitute 50% of our Board. Each of these events could be an event of default under the terms of the credit facility. The terms of the Purchase Agreement covering our subordinated notes provide that if Dr. Centofanti ceases to be our President and Chief Executive Officer, the holders of the subordinated notes have the option to require us to prepay all amounts owing under the subordinated notes. As of the date of this prospectus, we owe under the subordinated notes the principal sum of $5.6 million, which principal sum is due in full on July 31, 2006. The Purchase Agreement covering the subordinated notes also provides that if any person or group is successful in electing its nominees to 50% or more of the positions on our Board, then the holders of the Subordinated Notes have the option to require us to prepay all amounts owing under the Subordinated Notes, plus a prepayment premium. If anyone or a group were to successfully attempt to cause any of these changes in our management or Board, we could be in default under our loan agreements. IF WE ARE UNABLE TO MAINTAIN OUR DOE SUBCONTRACTS, OR THE SUBCONTRACTS ARE DELAYED, WE COULD LOSE A PRIMARY REVENUE SOURCE. Currently, a material amount of our nuclear segment's revenues are generated pursuant to subcontracts under contracts with the U. S. Department of Energy (the "DOE"). Each subcontract provides that the contractor, on its or the DOE's behalf, may terminate or delay each contract under which the subcontracts were issued at any time by notifying us. If we fail to maintain, renew, or replace these contracts, our revenues could be materially reduced, and your investment could be materially and adversely affected. We have significant revenues under subcontracts granted to our nuclear segment by Bechtel Jacobs Company, LLC, a contractor to the DOE, which were approximately $13,139,000, and $9,664,000, representing 15.5% and 11.6%, respectively, of our consolidated revenues for 2003 and 2002. 4 THE INABILITY TO COMPLETE EXISTING GOVERNMENT CONTRACTS OR WIN NEW GOVERNMENT CONTRACTS OVER AN EXTENDED PERIOD COULD HARM OUR OPERATIONS AND ADVERSELY AFFECT OUR FUTURE REVENUES. 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 increases overall competition and pricing pressure and may require us to make sustained post-award efforts to realize revenues under these government contracts. In addition, government clients can generally terminate or modify their contracts at their convenience. The inability to complete existing government contracts or win new government contracts over an extended period could harmimpact our operations and adversely affect our future revenues. IF WE CANNOT MAINTAIN OUR GOVERNMENTAL PERMITS OR CANNOT OBTAIN REQUIRED PERMITS, WE MAY NOT BE ABLE TO CONTINUE OR EXPAND OUR OPERATIONS. Wepermits which we are a waste management company. Our business is subjectrequired to extensive, evolving, and increasingly stringent federal, state, and local environmental laws and regulations. Such federal, state, and local environmental laws and regulations governhave in order to operate our activities regarding the treatment, storage, recycling,and disposal and transportation of hazardous and non-hazardous waste and low-level radioactive waste. We must obtain and maintain permits, licenses and/or approvals to conduct these activities in compliance with such laws and regulations. Failure to obtain and maintain the required permits, licenses and/or approvals would have a material adverse effect on our operations and financial condition. facilities.

If we arecannot maintain adequate insurance coverage, we will be unable to maintain our currently held permits, licenses, and/or approvals or obtain any additional permits, licenses and/or approvals which may be required as we expand our operations, we may not be able to continue certain of our operations. See "Risk Factors - Our Industrial waste management services and nuclear waste management services subject us to potential environmental liability." CHANGES IN ENVIRONMENTAL REGULATIONS AND ENFORCEMENT POLICIES COULD SUBJECT US TO ADDITIONAL LIABILITY AND ADVERSELY AFFECT OUR ABILITY TO CONTINUE CERTAIN OPERATIONS. Because the environmental industry continues to develop rapidly, we cannot predict the extent to which our operations may be affected by future 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. IF WE ARE UNABLE TO MAINTAIN PROFITABILITY, WE MAY BE UNABLE TO COMPLY WITH CERTAIN GOVERNMENT REGULATIONS AND COULD BECOME SUBJECT TO SUBSTANTIAL FINES OR LOSE OUR PERMITS. The standards imposed by federal, state, and local environmental laws require us to incur additional expenses as necessary to upgrade our facility. If we are unable to continue to be profitable on a long-term basis, our ability to remain in compliance with various federal, state, and local environmental regulations would be impaired. Violation of such federal, state, and local regulations could result in the loss of one or more of our permits or subject us to substantial fines, penalties, or other liabilities that could have a material adverse impact on our financial condition and our ability to continue certain of our operations. OUR INDUSTRIAL WASTE MANAGEMENT SERVICES AND NUCLEAR WASTE MANAGEMENT SERVICES SEGMENTS SUBJECT US TO POTENTIAL ENVIRONMENTAL LIABILITY. Our business of rendering services in connection with management of waste, including certain types of hazardous waste and low-level radioactive waste, subjects us to risks of liability for damages. Such liability could involve, without limitation: o 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; 5 o claims of employees, customers, or third parties for personal injury or property damage occurring in the course of our operations; and o 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. During the first quarter of 2004, we discovered that one of our subsidiaries has been storing a substantial amount of hazardous and non-hazardous waste in violation of certain environmental laws. We voluntarily reported this matter to the appropriate state governmental authorities and have removed this waste to permitted treatment, storage, and/or disposal facilities ("TSD facilities"). As of the date of this prospectus, the state has not advised us as to what action or actions, if any, it intends to take against our subsidiary as a result of this matter. The state could assert monetary fines and penalties or take other action against our subsidiary as a result of this matter (including, but not limited to, loss of permits), which may have a material adverse effect upon us. 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 regulated by numerous laws 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 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. 6 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. 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

The inability to a seasonal slowdown in operations from poor weather conditions and overall reduced activities during these periods. This trend has continued through the first quarter of 2004. During the first quarter of 2004, we had unaudited revenues of $17.5 million and net loss applicable to common stockholders of $2.0 million, as compared to unaudited revenues of $19.5 million and net loss applicable to common stockholders of $431,000 for the first quarter of 2003. See below "Risk Factors - - Our Industrial waste management services segment has sustained substantial losses, which, if continuing, may have a material adverse effect on your investment in our common stock." During our second and third fiscal quarters there has historically beenmaintain existing government contracts or win new government contracts over 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 willextended period could have a material adverse effect on our resultsoperations and adversely affect our future revenues.

A material amount of operation and liquidity. OUR INDUSTRIAL WASTE MANAGEMENT SERVICES SEGMENT HAS SUSTAINED SUBSTANTIAL LOSSES WHICH, IF CONTINUING, COULD HAVE A MATERIAL ADVERSE EFFECT ON YOUR INVESTMENT IN OUR COMMON STOCK. Theour 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 industrial waste management services segment constitutedNuclear Segment were approximately 52.1%$43,464,000 and 45.1%$30,000,000, representing 57.6% and 46.5%, respectively, of our consolidated operating revenues in 2003from continuing operations for 2008 and 2002, respectively, and 41.6%2007.  Most of our consolidatedgovernment 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 duringunder these government contracts. All contracts with, or subcontracts involving, the first quarterfederal government are terminable, or subject to renegotiation, by the applicable governmental agency on 30 days notice, at the option of 2004. Our industrial waste management services segment sustained lossesthe governmental agency.  If we fail to maintain or replace these relationships, or if a material contract is terminated or renegotiated in 2003 and 2002 of approximately $2.0 million and $3.9 million, respectively. This segment has also sustained an unaudited loss of $2.5 million for the first quarter of 2004, as compareda manner that is materially adverse to a loss of $828,000 during the first quarter of 2003. This segment is generally adversely affected by economic downturns, due, in part, to reductions in industrial production that result in reduced levels of hazardous and non-hazardous waste. We believe that theus, our revenues and profits in this segment were negatively impacted by the downturn in our economy that began in 2001 and continued during part of the first quarter of 2004. During the fourth quarter of 2003, we completed a restructuringfuture operations could be materially adversely affected.

Failure of our industrial waste management services segment, changing this segment's managementNuclear 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 increasing itsthe 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 higher-margin generator direct revenuesthe efficient operation of our existing facilities within our Nuclear Segment and eliminating lower-margin outside broker revenues. During March 2004, we completed certainto further evaluate strategic acquisitions inwithin the industrial waste management services segment. See "Recent Developments - Acquisitions."Nuclear Segment. If our industrial waste management services segmentNuclear Segment fails to becomecontinue to be profitable on an annualized basis in the foreseeable future, this could have a material adverse effect on ourthe Company’s results of operations, liquidity and our potential growth. IF WE ARE UNABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY, OUR GROWTH COULD BE LIMITED.

Our success is dependentexisting 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 abilitybusinesses.

Demand for our services has been, and we expect that demand will continue to maintainbe, subject to significant fluctuations due to a variety of factors beyond our proprietary technologies. There can be no assurancecontrol, 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 steps taken by usfederal government has and is continuing to protect our proprietary technologiesincur.  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 adequategenerally 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 prevent misappropriationour business could have a material adverse impact on our business, financial position, results of these technologies by third parties. Misappropriationoperations 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 proprietary technologyrevenue 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 operationsbusiness and financial condition. Changesresults of operations.

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

Our governmental contracts, which are primarily with the useDOE or subcontracts relating to DOE sites, are a significant part of our proprietary technology. LOSS OF CERTAIN KEY PERSONNEL COULD HAVE A MATERIAL ADVERSE EFFECT ON US. 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. IF ENVIRONMENTAL REGULATION OR ENFORCEMENT IS RELAXED, THE DEMAND FOR OUR SERVICES WILL DECREASE.

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
5

·
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. 7 OUR OPERATIONS WILL SUFFER IF WE ARE UNABLE TO MANAGE OUR GROWTH.

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.
6

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 currently experiencingengaged 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 periodcompetitive advantage. In addition, even if we are qualified to work on a new government contract, we might not be awarded the contract because of growth through internal expansionexisting government policies designed to protect certain types of businesses and strategic acquisitions, including two acquisitions in March 2004. See "Recent Developments -- Acquisitions." This growth has placed, and could continue to place, a significant strainunderrepresented minority contractors. Competition also places downward pressure on our management, personnel,contract prices and other resources. Our growth requires us to effectively manage our collaborative arrangements andprofit margins. Intense competition is expected to continue to improve our operational, management, and financial systems and controls, and to successfully train, motivate, and manage our employees.for nuclear service contracts. If we are unable to effectively managemeet these competitive challenges, we could lose market share and experience on overall reduction in our growth,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 realizebe 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 expected benefitstreatment, 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 growth,laws and such failure couldregulations. Failure to obtain and maintain the required permits or licenses would have a material adverse effect on our operations and financial condition. WE DO NOT INTEND TO PAY DIVIDENDS ON OUR COMMON STOCK IN THE FORESEEABLE FUTURE. 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 December 31, 2008, we had 53,934,560 shares of Common Stock outstanding.

In addition, as of December 31, 2008, we had outstanding options to purchase 3,417,347 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. We intend to retain future earnings, if any, to provide funds for the operation and/or expansion of our business. The terms of the Series 17 Preferred allow us to pay dividends on the outstanding Series 17 Preferred in cash or common stock. We currently intend to pay the dividends accruing on the Series 17 Preferred in common stock if, and when, declared and paid by our Board of Directors. The actual number of shares of common stock issuable in payment of accrued dividends on the Series 17 Preferred will depend upon the length of time the Series 17 Preferred is outstanding and the price of the common stock at the time of payment of dividends. Our Credit Facility prohibits us from paying cash dividends (including cash dividends on our Series 17 Preferred) withoutcommon 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 lender's prior written consent. EXPIRATION OF THE PRICE-ANDERSON ACT'S INDEMNIFICATION AUTHORITY COULD HAVE ADVERSE CONSEQUENCES ON OUR POWER, DEFENSE, AND ENERGY & ENVIRONMENT BUSINESS UNITS.Nasdaq Capital Markets constantly changes. We provide servicesexpect 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 nuclear industry. The Price-Anderson Act promoteseffect, if any, that future issuances or sales of shares of common stock or the nuclear industry by offering broad indemnification to commercial nuclear power plant operators and DOE contractorsavailability of shares of common stock for liabilities arising outfuture issuance, will have on the trading price of nuclear incidents at power plants licensed by the NRC and at DOE nuclear facilities. That indemnification protects not only the NRC license or DOE prime contractor, butour common stock.  Such future issuances could also others like us who may be doing work under contract or subcontract for a licensed power plant or under a DOE prime contract. While the Price-Anderson Act's indemnification provisions are broad, it has not been determined whether they apply to all liabilities that might be incurred by a radioactive materials cleanup contractor. Moreover, the Price-Anderson Act indemnification authority expired on December 31, 2003, for NRC licensees, and it will expire on December 31, 2004 for DOE contractors. There are legislative proposals to enact a long-term extension of Price Anderson indemnification authority, as has been done several times in the past. Those proposals are part of the omnibus energy legislation that is pending in Congress. However, that bill has been held up during the last several legislative sessions for reasons unrelated to Price Anderson. DOE contractors who have coverage under current contracts would be unaffected by the expiration of authority at the end of the year. Their coverage continues until the contract under which the indemnification was granted terminates. However, our federal business could be adversely affected if DOE prime contractors are reluctant to enter into new contracts involving nuclear hazards in the absence of an extension of Price Anderson indemnification authority for them after December 31, 2004. DOE has alternative, although more limited, indemnification authority under Public Law 85-804, and when Price Anderson has temporarily lapsed in the past, DOE prime contractors were generally willing to accept that coverage on an interim basis. Private insurers, however, have generally not been willing to cover nuclear hazards associated with DOE work.

Additional authorization of shares of common stock could be used by incumbentour management to make it more difficult, and thereby discourage an attempt to acquire control of us, even thoughus.

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 deem such an acquisition desirable.also have the effect of deterring, delaying, or preventing a change in control that might otherwise be in the best interests of our stockholders.

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.

We sold to 15 accredited investors 4,616,113 shares of common stock at $2.25 per share and warrants for the purchase of up to an additional 1,615,638 shares of common stock. The warrants have an exercise price of $2.92 per share and a three year term. The warrants may be exercised pursuant to a cashless exercise option if, at any time after one year from the date of issuance of the warrants, there is no effective registration statement registering the resale of the shares issuable upon exercise of the warrants and such shares are not eligible to be sold pursuant to Rule 144(k) of the Securities Act. We realized net proceeds from the private placement of approximately $9.9 million, after paying fees of $515,000 to the placement agent and certain expenses of the placement agent. The net proceeds were used as follows: o $2.9 million in connection with a certain acquisition discussed below; and o the remaining $7.0 million to reduce debt, make certain capital expenditures and for working capital purposes. As compensation for consulting services in connection with the private placement, we issued warrants ("Consultant Warrants") to outside consultants to purchase an aggregate of 160,000 shares of our common stock, subject to adjustment. The Consultant Warrants have an exercise price of $2.92 per share and a three year term. The exercise price of, and number of shares of common stock issuable upon exercise of, the warrants and Consulting Warrants are each subject to adjustment upon certain events. These events include, among others, stock splits and reclassifications of our common stock, and certain reorganizations, mergers and consolidations. The issuance of shares, warrants and Consultant Warrants described above was made pursuant to a private placement under Section 4(2) and/or Regulation D of the Securities Act. The shares issued

We also acquired certain assets of US Liquids of Pennsylvania d/b/a EMAX ("EMAX"), located in Pittsburgh, Pennsylvania. We paid $2.9 million in cash for these assets. A&A and EMAX had unaudited combined revenues in 2003 of approximately $15 million and had an unaudited combined net loss of approximately $299,000. A&A is a full line provider of environmental, marine and industrial maintenance services.

EMAX, through its field and industrial services group, provides a variety of environmental services such as transportation of drums and bulk loads, tank cleaning, industrial maintenance, dewatering, drum management and chemical packaging. EMAX also has a wastewater treatment group, which provides for the treatment of non-hazardous wastewaters such as leachates, oily waters, industrial process waters and off-spec products.
