 Exhibit 10.31 
 HECKMANN CORPORATION 
 RESTRICTED STOCK AGREEMENT 
 Heckmann Corporation (the “Company”) has granted to the Participant named in the Notice of Grant of Restricted
Stock (the “Grant Notice”) to which this Restricted Stock Agreement (the “Agreement”) is attached an Award consisting of Shares subject to the terms and conditions set
forth in the Grant Notice and this Agreement. The Award has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Heckmann Corporation 2009 Equity Incentive Plan (the
“Plan”), as amended to the Date of Grant, the provisions of which are incorporated herein by reference. By signing the Grant Notice, the Participant: (a) acknowledges receipt of and represents that the
Participant has read and is familiar with the Grant Notice, this Agreement, the Plan and a prospectus for the Plan prepared in connection with the registration with the Securities and Exchange Commission of the Shares (the “Plan
Prospectus”), (b) accepts the Award subject to all of the terms and conditions of the Grant Notice, this Agreement and the Plan and (c) agrees to accept as binding, conclusive and final all decisions or interpretations
of the Committee upon any questions arising under the Grant Notice, this Agreement or the Plan. 
 1. DEFINITIONS
AND CONSTRUCTION. 
 1.1 Definitions. Unless
otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Grant Notice or the Plan. 
 1.2
Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Agreement. Except when otherwise indicated by the context, the singular
shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise. 
 2. ADMINISTRATION. 
 All questions of interpretation concerning the Grant Notice, this Agreement, the Plan or any other form of agreement or other document employed by the
Company in the administration of the Plan or the Award shall be determined by the Committee. All such determinations by the Committee shall be final, binding and conclusive upon all persons having an interest in the Award, unless fraudulent or made
in bad faith. Any and all actions, decisions and determinations taken or made by the Committee in the exercise of its discretion pursuant to the Plan or the Award or other agreement thereunder (other than determining questions of interpretation
pursuant to the preceding sentence) shall be final, binding and conclusive upon all persons having an interest in the Award. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or
election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election. 

 3. THE AWARD.

 3.1 Grant and Issuance of Shares. On the Date of Grant, the Participant shall acquire and the Company shall issue, subject to the
provisions of this Agreement, a number of Shares equal to the Total Number of Shares. As a condition to the issuance of the Shares, the Participant shall execute and deliver the Grant Notice to the Company, and, if required by the Company, an
Assignment Separate from Certificate duly endorsed (with date and number of shares blank) in the form provided by the Company. 
 3.2 No
Monetary Payment Required. The Participant is not required to make any monetary payment (other than to satisfy applicable tax withholding, if any, with respect to the issuance or vesting of the Shares) as a condition to receiving the Shares, the
consideration for which shall be past services actually rendered or future services to be rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable law, the Participant shall furnish
consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the Shares issued pursuant to the Award. 
 3.3 Beneficial Ownership of Shares; Certificate Registration. The Participant hereby authorizes the Company, in its sole discretion,
to deposit the Shares with the Company’s transfer agent, including any successor transfer agent, to be held in book entry form during the term of the Escrow pursuant to Section 6. Furthermore, the Participant hereby authorizes the Company,
in its sole discretion, to deposit, following the term of such Escrow, for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all Shares which are no longer
subject to such Escrow. Except as provided by the foregoing, a certificate for the Shares shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant. 
 3.4 Issuance of Shares in Compliance with Law. The issuance of the Shares shall be subject to compliance with all applicable
requirements of federal, state or foreign law with respect to such securities. No Shares shall be issued hereunder if their issuance would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations
or the requirements of any stock exchange or market system upon which the Stock may then be listed. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel
to be necessary to the lawful issuance of any Shares shall relieve the Company of any liability in respect of the failure to issue such Shares as to which such requisite authority shall not have been obtained. As a condition to the issuance of the
Shares, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may
be requested by the Company. 
 4. VESTING OF
SHARES. 
 Shares acquired pursuant to this Agreement shall become Vested
Shares as provided in the Grant Notice. For purposes of determining the number of Vested Shares following an Ownership Change Event, credited Service shall include all Service with any 

  

 2 

 
corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and
after the Ownership Change Event. 
 5. COMPANY REACQUISITION
RIGHT. 
 5.1 Grant of Company Reacquisition Right. In
the event that (a) the Participant’s Service terminates for any reason or no reason, with or without cause, or (b) the Participant, the Participant’s legal representative, or other holder of the Shares, attempts to sell,
exchange, transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership Change Event), including, without limitation, any transfer to a nominee or agent of the Participant, any Shares which are not Vested Shares
(“Unvested Shares”), the Participant shall forfeit and the Company shall automatically reacquire the Unvested Shares, and the Participant shall not be entitled to any payment therefor (the
“Company Reacquisition Right”). 
 5.2 Ownership Change Event, Dividends, Distributions and
Adjustments. Upon the occurrence of an Ownership Change Event, a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure
of the Company as described in Section 9, any and all new, substituted or additional securities or other property (other than regular, periodic dividends paid on Stock pursuant to the Company’s dividend policy) to which the Participant is
entitled by reason of the Participant’s ownership of Unvested Shares shall be immediately subject to the Company Reacquisition Right and included in the terms “Shares,” “Stock” and “Unvested Shares” for all
purposes of the Company Reacquisition Right with the same force and effect as the Unvested Shares immediately prior to the Ownership Change Event, dividend, distribution or adjustment, as the case may be. For purposes of determining the number of
Vested Shares following an Ownership Change Event, dividend, distribution or adjustment, credited Service shall include all Service with any corporation which is a Participating Company at the time the Service is rendered, whether or not such
corporation is a Participating Company both before and after any such event. 
 6.
ESCROW. 
 6.1 Appointment of Agent. To ensure that Shares
subject to the Company Reacquisition Right will be available for reacquisition, the Participant and the Company hereby appoint the Secretary of the Company, or any other person designated by the Company, as their agent and as attorney-in-fact for
the Participant (the “Agent”) to hold any and all Unvested Shares and to sell, assign and transfer to the Company any such Unvested Shares reacquired by the Company pursuant to the Company Reacquisition Right.
The Participant understands that appointment of the Agent is a material inducement to make this Agreement and that such appointment is coupled with an interest and is irrevocable. The Agent shall not be personally liable for any act the Agent may do
or omit to do hereunder as escrow agent, agent for the Company, or attorney in fact for the Participant while acting in good faith and in the exercise of the Agent’s own good judgment, and any act done or omitted by the Agent pursuant to the
advice of the Agent’s own attorneys shall be conclusive evidence of such good faith. The Agent may rely upon any letter, notice or other document executed by any signature purporting to be genuine and may resign at any time. 
  

 3 

 6.2 Establishment of Escrow. The Participant authorizes the Company to deposit the
Unvested Shares with the Company’s transfer agent to be held in book entry form, as provided in Section 3.3, and the Participant agrees to deliver to and deposit with the Agent each certificate, if any, evidencing the Shares and, if
required by the Company, an Assignment Separate from Certificate with respect to such book entry shares and each such certificate duly endorsed (with date and number of Shares blank) in the form attached to this Agreement, to be held by the Agent
under the terms and conditions of this Section 6 (the “Escrow”). Upon the occurrence of an Ownership Change Event, a dividend or distribution to the stockholders of the Company paid in shares of Stock or
other property (other than regular, periodic dividends paid on Stock pursuant to the Company’s dividend policy) or any other adjustment upon a change in the capital structure of the Company, as described in Section 9, any and all new,
substituted or additional securities or other property to which the Participant is entitled by reason of his or her ownership of the Shares that remain, following such Ownership Change Event, dividend, distribution or change described in
Section 9, subject to the Company Reacquisition Right shall be immediately subject to the Escrow to the same extent as the Shares immediately before such event. The Company shall bear the expenses of the Escrow. 
 6.3 Delivery of Shares to Participant. The Escrow shall continue with respect to any Shares for so long as such Shares remain
subject to the Company Reacquisition Right. Upon termination of the Company Reacquisition Right with respect to Shares, the Company shall so notify the Agent and direct the Agent to deliver such number of Shares to the Participant. As soon as
practicable after receipt of such notice, the Agent shall cause the Shares specified by such notice to be delivered to the Participant, and the Escrow shall terminate with respect to such Shares. 
 7. TAX MATTERS. 
 7.1 Tax Withholding. 
 (a) In
General. At the time the Grant Notice is executed, or at any time thereafter as requested by a Participating Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise
agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax (including any social insurance) withholding obligations of the Participating Company, if any, which arise in connection with the Award,
including, without limitation, obligations arising upon (a) the transfer of Shares to the Participant, (b) the lapsing of any restriction with respect to any Shares, (c) the filing of an election to recognize tax liability, or
(d) the transfer by the Participant of any Shares. The Company shall have no obligation to deliver the Shares or to release any Shares from the Escrow established pursuant to Section 6 until the tax withholding obligations of the
Participating Company have been satisfied by the Participant. 
 (b) Withholding in Shares. The Company shall have the right, but not
the obligation, to require the Participant to satisfy all or any portion of a Participating Company’s tax withholding obligations by withholding a number of whole, Vested Shares otherwise deliverable to the Participant or by the
Participant’s tender to the Company of a number of whole, Vested Shares or vested shares acquired otherwise than pursuant to the Award having, in any such case, a fair market value, as determined by the Company as of the date on 

  

 4 

 
which the tax withholding obligations arise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory
withholding rates. 
 7.2 Election Under Section 83(b) of the Code. 
 (a) The Participant understands that Section 83 of the Code taxes as ordinary income the difference between the amount paid for the Shares, if
anything, and the fair market value of the Shares as of the date on which the Shares are “substantially vested,” within the meaning of Section 83. In this context, “substantially vested” means that the right of the Company
to reacquire the Shares pursuant to the Company Reacquisition Right has lapsed. The Participant understands that he or she may elect to have his or her taxable income determined at the time he or she acquires the Shares rather than when and as the
Company Reacquisition Right lapses by filing an election under Section 83(b) of the Code with the Internal Revenue Service no later than thirty (30) days after the date of acquisition of the Shares. The Participant understands that failure
to make a timely filing under Section 83(b) will result in his or her recognition of ordinary income, as the Company Reacquisition Right lapses, on the difference between the purchase price, if anything, and the fair market value of the Shares
at the time such restrictions lapse. The Participant further understands, however, that if Shares with respect to which an election under Section 83(b) has been made are forfeited to the Company pursuant to its Company Reacquisition Right, such
forfeiture will be treated as a sale on which there is realized a loss equal to the excess (if any) of the amount paid (if any) by the Participant for the forfeited Shares over the amount realized (if any) upon their forfeiture. If the Participant
has paid nothing for the forfeited Shares and has received no payment upon their forfeiture, the Participant understands that he or she will be unable to recognize any loss on the forfeiture of the Shares even though the Participant incurred a tax
liability by making an election under Section 83(b). 
 (b) The Participant understands that he or she should consult with his or her
tax advisor regarding the advisability of filing with the Internal Revenue Service an election under Section 83(b) of the Code, which must be filed no later than thirty (30) days after the date of the acquisition of the Shares pursuant to
this Agreement. Failure to file an election under Section 83(b), if appropriate, may result in adverse tax consequences to the Participant. The Participant acknowledges that he or she has been advised to consult with a tax advisor regarding the
tax consequences to the Participant of the acquisition of Shares hereunder. ANY ELECTION UNDER SECTION 83(b) THE PARTICIPANT WISHES TO MAKE MUST BE FILED NO LATER THAN 30 DAYS AFTER THE DATE ON WHICH THE PARTICIPANT ACQUIRES THE SHARES. THIS
TIME PERIOD CANNOT BE EXTENDED. THE PARTICIPANT ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE PARTICIPANT’S SOLE RESPONSIBILITY, EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH ELECTION
ON HIS OR HER BEHALF. 
 (c) The Participant will notify the Company in writing if the Participant files an election pursuant to
Section 83(b) of the Code. The Company intends, in the event it does not receive from the Participant evidence of such filing, to claim a tax deduction for any amount which would otherwise be taxable to the Participant in the absence of such an
election.

 8. EFFECT OF CHANGE IN
CONTROL. 
 In the event of a Change in Control, the surviving, continuing,
successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of the Participant, assume or continue in full force and effect the
Company’s rights and obligations under the Award or substitute for the Award a substantially equivalent award for the Acquiror’s stock. For purposes of this Section, the Award shall be deemed assumed if, following the Change in Control,
the Award confers the right to receive, subject to the terms and conditions of the Plan and this Agreement, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or
property or a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled. Notwithstanding the foregoing, Shares acquired pursuant to the Award prior to the Change in Control and any
consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Agreement except as otherwise provided herein. 
 9. ADJUSTMENTS FOR CHANGES IN CAPITAL
STRUCTURE. 
 Subject to any required action by the stockholders of the
Company, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in
a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number and kind of shares of stock or other property
subject to the Award, in order to prevent dilution or enlargement of the Participant’s rights under the Award. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without
receipt of consideration by the Company.” Any and all new, substituted or additional securities or other property to which Participant is entitled by reason of ownership of shares acquired pursuant to this Award will be immediately subject to
the provisions of this Award on the same basis as all shares originally acquired hereunder. Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be
determined by the Committee, and its determination shall be final, binding and conclusive. 
 10. RIGHTS
AS A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT. 
 The Participant shall have no rights as a stockholder with respect to any Shares subject to the Award until the date of the issuance of the Shares (as
evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the Shares
are issued, except as provided in Section 9. Subject to the provisions of this Agreement, the Participant shall exercise all rights and privileges of a stockholder of the Company with respect to Shares deposited in the Escrow pursuant to
Section 6. If the Participant 

  

 6 

 
is an Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a
Participating Company and the Participant, the Participant’s employment is “at will” and is for no specified term. Nothing in this Agreement shall confer upon the Participant any right to continue in the Service of a Participating
Company or interfere in any way with any right of the Participating Company Group to terminate the Participant’s Service at any time. 
 11. LEGENDS. 
 The Company may at any time place legends
referencing the Company Reacquisition Right and any applicable federal, state or foreign securities law restrictions on all certificates representing the Shares. The Participant shall, at the request of the Company, promptly present to the Company
any and all certificates representing the Shares in the possession of the Participant in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be
limited to, the following: 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS SET FORTH IN AN AGREEMENT
BETWEEN THIS CORPORATION AND THE REGISTERED HOLDER, OR HIS PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION.” 
 12. TRANSFERS IN VIOLATION OF AGREEMENT. 
 No Shares may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of, including by operation of law, in any manner
which violates any of the provisions of this Agreement and, except pursuant to an Ownership Change Event, until the date on which such shares become Vested Shares, and any such attempted disposition shall be void. The Company shall not be required
(a) to transfer on its books any Shares which will have been transferred in violation of any of the provisions set forth in this Agreement or (b) to treat as owner of such Shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such Shares will have been so transferred. In order to enforce its rights under this Section, the Company shall be authorized to give a stop transfer instruction with respect to the Shares to the Company’s
transfer agent. 
 13. MISCELLANEOUS PROVISIONS.

 13.1 Termination or Amendment. The Committee may terminate or amend the Plan or this Agreement at any time; provided, however, that
no such termination or amendment may adversely affect the Participant’s rights under this Agreement without the consent of the Participant unless such termination or amendment is necessary to comply with applicable law or government regulation.
No amendment or addition to this Agreement shall be effective unless in writing. 
 13.2 Nontransferability of the Award. The right to
acquire Shares pursuant to the Award shall not be subject in any manner to anticipation, alienation, sale, exchange, 

  

 7 

 
transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or
by the laws of descent and distribution. All rights with respect to the Award shall be exercisable during the Participant’s lifetime only by the Participant or the Participant’s guardian or legal representative. 
 13.3 Further Instruments. The parties hereto agree to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 13.4 Binding Effect. This Agreement shall inure to the benefit of the
successors and assigns of the Company and, subject to the restrictions on transfer set forth herein, be binding upon the Participant and the Participant’s heirs, executors, administrators, successors and assigns. 
 13.5 Delivery of Documents and Notices. Any document relating to participation in the Plan or any notice required or permitted hereunder shall be
given in writing and shall be deemed effectively given (except to the extent that this Agreement provides for effectiveness only upon actual receipt of such notice) upon personal delivery, electronic delivery at the e-mail address, if any, provided
for the Participant by a Participating Company, or upon deposit in the U.S. Post Office or foreign postal service, by registered or certified mail, or with a nationally recognized overnight courier service, with postage and fees prepaid, addressed
to the other party at the address of such party set forth in the Grant Notice or at such other address as such party may designate in writing from time to time to the other party. 
 (a) Description of Electronic Delivery. The Plan documents, which may include but do not necessarily include: the Plan, the Grant
Notice, this Agreement, the Plan Prospectus, and any reports of the Company provided generally to the Company’s stockholders, may be delivered to the Participant electronically. In addition, if permitted by the Company, the parties may deliver
electronically any notices called for in connection with the Escrow and the Participant may deliver electronically the Grant Notice to the Company or to such third party involved in administering the Plan as the Company may designate from time to
time. Such means of electronic delivery may include but do not necessarily include the delivery of a link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail or such
other means of electronic delivery specified by the Company. 
 (b) Consent to Electronic Delivery. The Participant acknowledges that
the Participant has read Section 13.5(a) of this Agreement and consents to the electronic delivery of the Plan documents and, if permitted by the Company, the delivery of the Grant Notice and notices in connection with the Escrow, as described
in Section 13.5(a). The Participant acknowledges that he or she may receive from the Company a paper copy of any documents delivered electronically at no cost to the Participant by contacting the Company by telephone or in writing. The
Participant further acknowledges that the Participant will be provided with a paper copy of any documents if the attempted electronic delivery of such documents fails. Similarly, the Participant understands that the Participant must provide the
Company or any designated third party administrator with a paper copy of any documents if the attempted electronic delivery of such documents fails. The Participant may revoke his or her 

  

 8 

 
consent to the electronic delivery of documents described in Section 13.5(a) or may change the electronic mail address to which such documents are to be
delivered (if Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal service or electronic mail. Finally, the Participant understands that he
or she is not required to consent to electronic delivery of documents described in Section 13.5(a). 
 13.6 Integrated Agreement.
The Grant Notice, this Agreement and the Plan, together with any employment, service or other agreement between the Participant and a Participating Company referring to the Award, shall constitute the entire understanding and agreement of the
Participant and the Participating Company Group with respect to the subject matter contained herein or therein and supersede any prior agreements, understandings, restrictions, representations, or warranties among the Participant and the
Participating Company Group with respect to such subject matter. To the extent contemplated herein or therein, the provisions of the Grant Notice, this Agreement and the Plan shall survive any settlement of the Award and shall remain in full force
and effect. 
 13.7 Applicable Law. This Agreement shall be governed by the laws of the State of California as such laws are applied
to agreements between California residents entered into and to be performed entirely within the State of California. 
 13.8
Counterparts. The Grant Notice may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
