This Amendment No. 2 to Schedule 13D amends and supplements the Schedule 13D originally filed on July 27, 2016 (the “Original Schedule 13D”) as amended by Amendment No. 1 filed on July 25, 2017 (the Original Schedule 13D, as so amended, the “Amended Schedule 13D”), and is being filed jointly on behalf of Heartland Advisors, Inc., a Wisconsin corporation (“Heartland”), and William J. Nasgovitz, an individual (each a “Reporting Person,” and together, the “Reporting Persons”), relating to the common stock, $0.001 par value per share (the “Common Stock), of Perma-Fix Environmental Services, Inc., a Delaware corporation (the “Company”).  The purpose of this Amendment No. 2 to Schedule 13D is to report a change in the share ownership as a result of Heartland’s transactions in the Common Stock on behalf of its clients.

Unless otherwise defined or modified below, capitalized terms used in this Amendment No. 2 to Schedule 13D shall have the meaning ascribed to them in the Original Schedule 13D.

All disclosure for items contained in the Amended Schedule 13D where no new information is provided for such item in this Amendment No. 2 to Schedule 13D is incorporated herein by this reference.

Item 3.

Source and Amount of Funds or Other Consideration

Heartland has beneficially owned shares of Common Stock on behalf of Client Accounts for a number of years.  As of September 5, 2017, Heartland had acquired an aggregate of 1,419,439 shares of the Company’s Common Stock.  All shares of Common Stock held by Heartland on behalf of the Client Accounts were purchased with funds provided by the Client Accounts.

Item 5.

Interest in Securities of the Issuer

The aggregate percentage of shares of Common Stock reported owned by each person named herein is based upon 11,713,928 shares outstanding, which is the total number of shares of Common Stock outstanding as of August 8, 2017, as reported in the Company’s Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission on August 9, 2017.

As of September 5, 2017, as investment adviser to the Client Accounts, Heartland may be deemed the beneficial owner of 1,419,439 shares, or approximately 12.1%, of the Company’s Common Stock.  The clients of Heartland, a registered investment adviser, including a series of a registered investment company and other managed accounts, have the right to receive or the power to direct the receipt of dividends and proceeds from the sale of shares of the Company’s Common Stock held by Heartland included in this Schedule 13D.  The Heartland Value Fund, a series of Heartland Group, Inc., a registered investment company, owns greater than 5% of the Common Stock of the Company.  Any remaining shares of Common Stock disclosed in this filing as owned by Heartland and Mr. Nasgovitz are owned by various other Client Accounts managed by Heartland on a discretionary basis.  To the best of Heartland’s knowledge, as of September 5, 2017, none of the other Client Accounts owns more than 5% of the shares of the Company’s Common Stock outstanding.

Heartland, as investment adviser to the Client Accounts, may be deemed to have shared voting power with respect to 1,247,833 shares and shared dispositive power with respect to 1,419,439 shares of Common Stock.  Mr. Nasgovitz, as a control person of Heartland, may be deemed to have shared voting power with respect to 1,247,833shares of the Company’s Common Stock and shared dispositive power with respect to 1,419,439 shares and may thus be deemed the indirect beneficial owner of the shares beneficially owned by Heartland.  Mr. Nasgovitz specifically disclaims beneficial ownership of such shares.

A description of any transactions in the Common Stock by Heartland on behalf of its clients during the past sixty (60) days from the date hereof is set forth on Annex 2 attached hereto and incorporated herein by reference.
