Section 1 - Registrant's Business and Operations

Item 1.01.  Entry into a Material Definitive Agreement.

      On June 13, 2007, Perma-Fix  Environmental  Services,  Inc.  ("Perma-Fix")
entered  into a First  Amendment  to  Agreement  and Plan of Merger  (the "First
Amendment")  with  Nuvotec  USA,  Inc.   ("Nuvotec"),   Nuvotec's  wholly  owned
subsidiary,  Pacific  EcoSolutions,  Inc. ("PEcoS") and Perma-Fix's wholly owned
subsidiary, PESI Transitory, Inc. ("Transitory"). The First Amendment amends the
terms of the Agreement and Plan of Merger,  dated April 27, 2007  (together with
the First Amendment, the "Merger Agreement"), among such parties, which provides
for the  acquisition  of Nuvotec by Perma-Fix by means of a merger of Transitory
into  Nuvotec,  with  Nuvotec  surviving  as  the  wholly  owned  subsidiary  of
Perma-Fix.

      The First  Amendment  provides  that the total cash amount of the purchase
price to be paid at closing to the Nuvotec stockholders in the merger is reduced
from $2.5  million  to $2.3  million  and that the  maximum  aggregate  earn-out
payable  under the  Merger  Agreement  during the four year  earn-out  period is
reduced from $4.6 million to $4.4  million.  These  reductions  replace  certain
closing  date  purchase  price  adjustments  contained  in the  original  Merger
Agreement.  The  First  Amendment  also  permits  Nuvotec  to use  approximately
$644,000 of the  proceeds  received by Nuvotec  upon the exercise of its options
and warrants prior to the closing to pay certain expenses incurred by Nuvotec in
connection with the merger.

      As disclosed in Item 2.01 of this report,  which is incorporated into this
Item 1.01 by this reference, the merger was completed on June 13, 2007.

Section 2 - Financial Information

Item 2.01. Completion Of Acquisition Or Disposition Of Assets

      On June 13, 2007,  Perma-Fix  acquired  Nuvotec and Nuvotec's wholly owned
subsidiary,  PEcoS,  pursuant  to the  terms of the  Merger  Agreement,  between
Perma-Fix, Perma-Fix's wholly owned subsidiary,  Transitory, Nuvotec, and PEcoS.
The acquisition was structured as a reverse subsidiary  merger,  with Transitory
being merged into Nuvotec,  and Nuvotec being the  surviving  corporation.  As a
result of the merger,  Nuvotec  became a wholly owned  subsidiary  of Perma-Fix,
Nuvotec's name was changed to Perma-Fix Northwest, Inc. ("PESI Northwest"),  and
PEcoS is a  wholly-owned  subsidiary  of PESI  Northwest.  PEcoS is a  permitted
hazardous, low level radioactive and mixed waste treatment, storage and disposal
facility  located in the Hanford U.S.  Department  of Energy site in the eastern
part of the state of Washington.

      As  consideration  for the  merger,  Perma-Fix  agreed to pay the  Nuvotec
shareholders the sum of approximately $11.2 million, payable as follows:

(a)   $2.3 million in cash at closing of the merger;

(b)   an  earn-out  amount not to exceed  $4.4  million  over a four year period
      ("Earn-Out Amount"), with the first $1.0 million of the Earn-Out Amount to
      be  placed  in  an  escrow  account  to  satisfy  certain  indemnification
      obligations  under  the  Merger  Agreement  of  Nuvotec,  PEcoS,  and  the
      shareholders  of Nuvotec to  Perma-Fix  that are  identified  by Perma-Fix
      within two years following the merger; and

                                       2


(c)   payable only to the  shareholders  of Nuvotec that qualified as accredited
      investors  pursuant  to Rule 501 of  Regulation  D  promulgated  under the
      Securities Act of 1933, as amended (the "Act"):

      o     $2.3  million,  payable  over  a four  year  period,  unsecured  and
            nonnegotiable  and bearing an annual rate of interest of 8.25%, with
            (i)  accrued   interest   only  payable  on  June  30,  2008,   (ii)
            $833,333.33,  plus accrued and unpaid interest,  payable on June 30,
            2009, (iii) $833,333.33,  plus accrued and unpaid interest,  payable
            on June 30, 2010, and (iv) the remaining unpaid  principal  balance,
            plus  accrued  and  unpaid  interest,   payable  on  June  30,  2011
            (collectively, the "Installment Payments"). The Installment Payments
            may be prepaid at any time by Perma-Fix without penalty; and

      o     709,220 shares of Perma-Fix common stock, with such number of shares
            determined by dividing $2.0 million by 95% of average of the closing
            price of the  common  stock as quoted on the  Nasdaq  during  the 20
            trading days period  ending five  business days prior to the closing
            of the merger.

      At the closing of the  merger,  the Nuvotec  debt was  approximately  $9.3
million,  and the debt of PEcoS was approximately $3.7 million,  with a total of
approximately $8.8 million owing to KeyBank National Association. Perma-Fix paid
approximately $4.8 million of the KeyBank debt immediately upon closing.  Of the
amount of remaining  debt, $4.0 million is owed by PESI Northwest under a credit
facility with KeyBank.  The KeyBank credit  facility and a related $1.75 million
line of credit with KeyBank is  guaranteed by Robert L.  Ferguson,  who prior to
the merger was the  Chairman and Chief  Executive  Officer of Nuvotec and PEcoS,
and  William  Lampson,  who  prior to the  merger  was the  vice-chairman  and a
vice-president of Nuvotec and PEcoS

      In connection with the merger,  Perma-Fix agreed to increase the number of
its directors from seven to eight and to take reasonable  action to nominate and
recommend  Mr.  Ferguson  for  election  as a  member  of  Perma-Fix's  board of
directors. Accordingly, Mr. Ferguson has been nominated by Perma-Fix's Corporate
Governance  and  Nominating  Committee  for  election  to  the  Board,  and  his
nomination will be subject to the vote of Perma-Fix's stockholders at the annual
meeting  scheduled for August 2, 2007.  At the closing of the merger,  Perma-Fix
paid Mr. Ferguson and entities controlled by him, as accredited  stockholders in
Nuvotec,  a total of  $224,560  cash  and will be issue to him and the  entities
controlled  by him a total  of  192,783  shares  of  Perma-Fix  common  stock in
consideration  for the merger.  Mr. Ferguson and the entities  controlled by him
will also be  entitled  to receive  their  proportionate  share of the  Earn-Out
Amount and the Installment Payments under the terms of the Merger Agreement.

      Prior to the  merger,  Nuvotec  completed  the  transfer of certain of its
assets,  including  the spin off to the  shareholders  of  Nuvotec of the common
stock of Nuvotec's  majority  owned  subsidiary,  Vivid Learning  Systems,  Inc.
(OTCBB:VVDL).

      Perma-Fix's press release,  dated June 14, 2007, announcing the completion
of the merger is attached as Exhibit 99.1 hereto and is  incorporated  into this
Item 1.01 by this reference.

Section 3 - Securities and Trading Markets

Item 3.02. Unregistered Sales of Equity Securities

      On June 13, 2007,  Perma-Fix  agreed to issue a total of 709,220 shares of
Perma-Fix  common stock to the 82 former  shareholders of Nuvotec that qualified
as accredited  investors  (as defined in Rule 501 of  Regulation  D). The shares
will be issued as part of the  consideration  for the  acquisition  by merger of
Nuvotec pursuant to the Merger Agreement.  The number of shares to be issued was
determined  by dividing  $2.0 million by 95% of average of the closing  price of
the common  stock as quoted on the Nasdaq  during  the 20  trading  days  period
ending five business days prior to the closing of the merger.  The issuance will
increase the number of issued and outstanding  shares of Perma-Fix  common stock
from 52,165,113 to 52,874,333,  based on the number of shares  outstanding as of
June 1, 2007,  2007.  Each of the investors in the common stock  represented  to
Perma-Fix  that  the  investor  is  "accredited"  for  purposes  of Rule  501 of
Regulation  D. The issuance of the common stock was made in a private  placement
exempt  from  registration  under  Section  4(2) of the Act  and/or  Rule 506 of
Regulation  D  promulgated  under the Act. See the  discussion  under Item 1.01,
above, which is incorporated in this Item 3.02 by this reference.
