 Exhibit 10.4 

CHANGE-IN-CONTROL SEVERANCE AGREEMENT 

This CHANGE-IN-CONTROL SEVERANCE AGREEMENT (the “Agreement”) is
entered into as of July 1, 2021 (the “Effective Date”) between DT Midstream, Inc., a Delaware corporation (the “Company”), and
                     (the “Executive”). 

RECITALS 
 The Executive is an
executive or a key employee of the Company or one or more of its Subsidiaries and has made and is expected to continue to make major contributions to the short- and long-term profitability, growth and financial strength of the Company. 

The Company recognizes that, as is the case for most publicly held companies, the possibility of a Change-in-Control exists and that potential employment uncertainty resulting from a Change-in-Control may distract management
from conducting the Company’s business or cause management employees to leave the Company. 
 The Company wants to provide security to its senior
executives and key employees to enable them to discharge their duties during the consideration and consummation of a Change-in-Control in order to preserve the value of
the Company for its shareholders. 
 In consideration of these objectives, the Company and the Executive agree as follows: 

 

	1.	 Term of Agreement. The term of this Agreement (the “Term”) begins on the Effective Date and
ends on the earlier of: 

  

	 	(a)	 the later of: 

  

	 	(1)	 the Agreement Expiration Date; or 

 

	 	(2)	 the last day of the Severance Period. 

or 
  

	 	(b)	 the date prior to a
Change-in-Control on which the Executive ceases for any reason to be an employee of the Company and any Subsidiary. For purposes of this Section 1(b), the Executive
does not cease to be an employee of the Company and any Subsidiary if the Executive’s employment is transferred between the Company and any Subsidiary, or among any Subsidiaries. 

 

	2.	 Right to Receive Severance Benefits and Other Consideration. The Executive will become entitled to the
severance benefits and other consideration provided under this Agreement if the Executive’s employment is terminated because of a Qualifying Termination. 

 

	3.	 Severance Benefits and Other Consideration. 

 

	 	(a)	 Severance Benefits. The Severance Benefits payable under this Agreement are all the following:

  

	 	(1)	 A lump sum payment equal to X% of the sum of: 

 

	 	(A)	 Base Salary; plus

	 	(i)	 the Annual Bonus for the year in which the
Change-in-Control occurs; or 

  

	 	(ii)	 the Annual Bonus for the year in which the Termination Date occurs, 

in either case based on the assumption that target performance goals for the applicable year would be met and the Executive was employed for
the entire year or until any later date required to receive the payment;] 
  

	 	(2)	 A lump sum payment equal to: 

 

	 	(A)	 [the greater of:

	 	(i)	 the numerator is the number of days prior to the Executive’s Termination Date during the calendar year in
which the Termination Date occurs; and 

  

	 	(ii)	 the denominator is 365, 

 

	 	(C)	 then reduced by the Annual Bonus for the year in which the Termination Date occurs that is payable to the
Executive under the terms of the Annual Plan if the Executive has attained age 55 and completed 10 years of service with the Company and all Subsidiaries. 

  

	 	(3)	 For Welfare Benefits provided to the Executive immediately prior to the Executive’s Termination Date (or,
if greater, immediately prior to reduction, termination, or denial), a lump sum payment equal to the present value of the cost of coverage for the Benefit Continuation Period. The cost of coverage will be determined at rates in effect as of the
Termination Date. The present value of the cost will be determined using an interest rate equal to the composite prime rate in effect as of the Termination Date in the Northeast Edition of The Wall Street Journal. 

 

	 	(4)	 Outplacement services by a firm selected by the Executive, at a cost to the Company in an amount up to 15% of
the Executive’s Base Salary. No payments by the Company for outplacement services will be made after December 31st of the calendar year following the calendar year including the Termination

	 	(2)	 Section 3(a)(2); 

 

	 	(3)	 Section 3(a)(3); 

 

	 	(4)	 Section 3(a)(4); 

 

	 	(5)	 Section 3(b); and 

 

	 	(6)	 (IF APPLICABLE) Section 3(c). 

Notwithstanding anything in this Agreement to contrary, consideration provided under Section 3(a)(5) above will be paid in accordance with
the terms of the LTIP. 
  

	 	(b)	 Withholding of Taxes. The Company will withhold from any amounts payable under this Agreement all
federal, state, city or other taxes that the Company is required to withhold under any law or government regulation or ruling. 

  

	 	(c)	 Interest. If the Company fails to make any payment or provide any benefit required to be made or
provided under this Agreement on a timely basis, the Company will pay interest on the amount or value at an annualized rate of interest equal to the composite prime rate as quoted from time to time during the relevant period in the Northeast Edition
of The Wall Street Journal. The interest is payable as it accrues on demand, but the Company is not required to pay interest more frequently than monthly. Any change in the prime rate will be effective on and as of the date of the change.

  

	 	(d)	 Severance Benefits Not Included in Other Compensation. The lump sum payments referenced in
Section 3 above will not be included in Executive’s earnings or compensation for purposes of calculating any benefits to which the Executive may be entitled to under any other employee benefit plan or program, including but not limited to
any qualified or non-qualified defined contribution plan calculation, post-employment benefit calculation, or 401(k) calculation. 

 

	5.	 Non-Duplication of Severance Benefits and Other Consideration.

  

	 	(a)	 Qualifying Termination During Concurrent Severance Periods. If the Executive experiences a Qualifying
Termination when two or more Severance Periods are running concurrently, as applicable (because two or more Changes-in-Control have occurred), the Executive will have a
Qualifying Termination with respect to each Severance Period. A determination of the payments and benefits to be provided under the Agreement will be made for each Qualifying Termination. However, the Executive will receive only:

  

	 	(1)	 the greatest lump sum payment under Section 3(a)(1) payable for any Qualifying Termination;

  

	 	(2)	 the greatest lump sum payment under Section 3(a)(2) for any Qualifying Termination; 

 

	 	(3)	 the greatest lump sum payment under Section 3(a)(3) for any Qualifying Termination;

For Executive Name 
  

	 	(4)	 one instance of outplacement assistance under Section 3(a)(4); 

 

	 	(5)	 the greatest of payments regarding any outstanding equity-based awards as called for under the terms and
conditions of the LTIP and any applicable award document; and 

  

	 	(6)	 the greatest lump sum payment under Section 3(b) for any Qualifying Termination; and

  

	 	(7)	 (IF APPLICABLE) the greatest lump sum payment under Section 3(c) for any Qualifying Termination.

  

	 	(b)	 Effect on Other Employee Benefits. The Executive’s Qualifying Termination will not affect any
rights the Executive may have under any agreement, policy, plan, program or arrangement of the Company or Subsidiary providing Employee Benefits (other than Severance Pay), which rights are governed by the terms of the agreement, policy, plan,
program or arrangement. The benefits received by an Executive under this Agreement because of a Qualifying Termination supersede and are in lieu of any other Severance Pay to which the Executive may be entitled. 

 

	6.	 No Mitigation. 

The Company acknowledges that it will be difficult and may be impossible for the Executive to find reasonably comparable employment following the Termination
Date. Accordingly, the Company acknowledges that payment of the severance compensation by the Company to the Executive under this Agreement is reasonable. The Executive is not required to mitigate the amount of any payment provided for in this
Agreement by seeking other employment or otherwise. No profits, income, earnings or other benefits from any source will create any mitigation, offset, reduction or other obligation on the part of the Executive, except as may have been otherwise paid
to the Executive by the Company or a Subsidiary in connection with or in consideration of Executive’s release and settlement of any claims arising out of the Executive’s employment or the termination of the Executive’s employment.

  

	7.	 Arbitration; Legal Fees and Expenses. 

 

	 	(a)	 Except for legal proceedings brought by the Executive or the Company for injunctive relief, any dispute or
claim involving this Agreement will be submitted to final and binding arbitration. The arbitration will take place in Oakland County, Michigan before a single neutral arbitrator under the then-current National Rules for the Resolution of Employment
Disputes of the American Arbitration Association. The arbitrator will issue a written opinion and will not have authority to render an award beyond the scope and specific terms of this Agreement. Judgment upon the arbitrator’s award may be
entered in any court of competent jurisdiction. Any demand for arbitration must be made within 30 days of when the party knew or should have known of the alleged dispute or claim. Failure to timely demand arbitration makes the dispute or claim non-arbitrable. The Executive and the Company expressly waive their rights to institute or prosecute any lawsuits or other court proceedings and waive their right to a jury trial, except for the legal proceedings
excluded above. 

  

	 	(b)	 It is the intent of the Company that the Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive’s rights under this Agreement because the legal fees and related expenses would substantially detract from the benefits intended to be extended to the Executive under this
Agreement.

	 	(c)	 If it appears to the Executive that the Company has failed to comply with any of its obligations under this
Agreement or if the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any action or proceeding designed to deny, or to recover from, the Executive the benefits provided
or intended to be provided to the Executive under this Agreement, the Company irrevocably authorizes the Executive to retain counsel of Executive’s choice, at the expense of the Company as provided in this Section 7, to advise and
represent the Executive in connection with any interpretation, enforcement or defense of the Executive’s rights under this Agreement. 

  

	 	(d)	 The Executive may pursue any legal defense of the Executive’s rights under this Agreement whether by or
against the Company or any Director, officer, stockholder or other person affiliated with the Company, in any jurisdiction. 

  

	 	(e)	 Whether or not the Executive prevails in connection with any defense of the Executive’s rights under this
Agreement, the Company will pay and be solely financially responsible for reasonable hourly attorneys’ fees and related fees and expenses incurred by the Executive under this Section 7, but only if the arbitrator determines the
Executive’s claim was brought in good faith and was not frivolous. If the Executive’s request for injunctive relief is denied and the Executive does not timely demand arbitration for the dispute or claim underlying the Executive’s
request for injunctive relief, the Executive’s request for injunctive relief is deemed to be frivolous and not brought in good faith for purposes of this Section 7(e). 

 

	 	(f)	 The Company’s payment of the Executive’s legal fees and expenses under this Section 7 following
termination of the Executive’s employment (whether or not in a Qualifying Termination) will be made during the first calendar year beginning after the date the Executive’s employment terminated. 

 

	8.	 Survival of Rights and Obligations. 

The rights and obligations of the Executive and the Company under the following Sections will survive the termination or expiration of this
Agreement and the termination of the Executive’s employment after a Change-in-Control for any reason: 

 

	 	(a)	 Section 2 (Right to Receive Severance Benefits and Other Consideration); 

 

	 	(b)	 Section 3 (Severance Benefits and Other Consideration); 

 

	 	(c)	 Section 4 (Timing of Payments); 

 

	 	(d)	 Section 5 (Non-Duplication of Severance Benefits and Other
Consideration); 

  

	 	(e)	 Section 6 (Mitigation); 

 

	 	(f)	 Section 7 (Legal Fees); and 

 

	 	(g)	 Section 20 (Definitions).

	 	(c)	 Non-Solicitation. 

 

	 	(1)	 For a period of two years after the Termination Date, the Executive will not solicit, divert, take away, or
attempt to take away any customer of the Company or any Subsidiary or the business of any customer of the Company or any Subsidiary. 

  

	 	(A)	 A “customer” of the Company or any Subsidiary is any person or other entity to which the Company or
any Subsidiary has sold services or products during the 24-month period immediately preceding the Termination Date, any person or other entity that the Company or any Subsidiary is in the process of selling
services or products, or any person or other entity to which the Company or any Subsidiary has submitted or is in the process of submitting a bid to sell services or products.

This Agreement is not intended to constitute a contract of employment for any specific term or period. Nothing in this Agreement creates any

the same extent the Company would be required to perform it if the succession had not taken place. This Agreement will be binding upon and inure to the benefit of the Company and any successor to the Company, including without limitation any person

	17.	 Counterparts. 

This Agreement may be executed in one or more counterparts, each of which is deemed an original but all of which together will constitute one
agreement. 
  

	18.	 Section 280G. 

This Section 18 will apply if the Executive is a “disqualified individual” within the meaning of
Section 1.280G-1, Q/A-15 of the Treasury regulations. In the event of an event constituting a change in the ownership or effective control of the Company or
ownership of a substantial portion of the assets of the Company described in Section 280G(b)(2)(A)(i) of the Code, the Company, at its sole expense, will cause its independent auditors promptly to review all payments, accelerations,
distributions and benefits that have been made to or provided to, and are to be made, or may be made, to or provided to, the Executive under the Agreement (irrespective of whether severance payment and benefits or other payments and benefits are
then payable to the Executive at that time), and any other agreement or plan under which the Executive may individually or collectively benefit (collectively the “Original Payments”), to determine the applicability of
Section 4999 of the Code to the Executive in connection with such event. The Company’s independent auditors will perform this analysis in conformity with the foregoing provisions and will provide the Executive with a copy of their analysis
and determination. Notwithstanding anything contained in this Agreement to the contrary, to the extent that the Original Payments would be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the
Original Payments will be reduced (but not below zero) to the extent necessary so that no Original Payment will be subject to the Excise Tax, but only if, by reason of such reduction, the net after-tax benefit
received by the Executive will exceed the net after-tax benefit received by him or her if no such reduction was made. For purposes of this Agreement, “net after-tax
benefit” will mean (a) the Original Payments which the Executive receives or is then entitled to receive from the Company that would constitute “parachute payments” within the meaning of Section 280G of the Code, less
(b) the amount of all federal, state and local income taxes payable with respect to the foregoing calculated at the maximum marginal income tax rate for each year in which the foregoing will be paid to the Executive (based on the rate in effect
for such year as set forth in the Code as in effect at the time of the first payment of the foregoing), less (c) the amount of the Excise Tax imposed with respect to the payments and benefits described in (a) above. If a reduction is
required by this provision, the payments and benefits will be reduced in the following order: any cash severance to which the Executive becomes entitled (starting with the last payment due), then other cash amounts that are parachute payments
(starting with the last payment due), then any stock option awards that have exercise prices higher than the then-fair market value price of the stock (based on the latest vesting tranches), then restricted stock and restricted stock units based on
the latest awards scheduled to be distributed, and then other stock options based on the latest vesting tranches. The fees and expenses of the Company’s auditor for its services in connection with the determinations and calculations
contemplated by this provision will be borne by the Company. 
  

	19.	 Section 409A. 

The Company intends that all payments and benefits provided under this Agreement or otherwise are exempt from, or comply with, the requirements
of Code Section 409A so that none of the payments or benefits will be subject to the additional tax imposed under Code Section 409A, and any ambiguities herein will be interpreted in accordance with such intent. For purposes of Code
Section 409A, each payment, installment or benefit payable under

 Change in Control Agreement 

For Executive Name 
  

 
this Agreement is hereby designated as a separate payment. “Termination of employment,” “resignation” or words of similar import, as used in this Agreement shall mean, with
respect to any payments subject to Code Section 409A, the Executive’s “separation from service” as defined by Code Section 409A. If any payment subject to Code Section 409A is contingent on the delivery of a release by
the Executive and could occur in either of two years, the payment will occur in the later year. In addition, if the Company determines that Executive is a “specified employee” under Code Section 409A(a)(2)(B)(i) at the time of
Executive’s separation from service, then (i) any severance payments or benefits, to the extent that they are subject to Code Section 409A, shall be paid the first business day after the end of such
six-month period, or, if earlier, within 30 days after the Executive’s death and (ii) any installments that otherwise would have been paid or provided prior to such date will be paid or provided in a
lump sum when the severance payments or benefits commence. 
  

	20.	 Definitions. 

For purposes of this Agreement, the following definitions apply: 
  

	 	(a)	 [Agreement Expiration Date is the later of: 

 

	 	(1)	 the day before the third anniversary of the Effective Date; or

WHEREAS, the Company desires to continue to retain the services of Executive; AND the parties desire to enter into this Agreement to set forth
certain terms and conditions under which Executive may be eligible to receive a Severance Payment (defined below) in the event of a termination from employment with the Company; 

NOW, THEREFORE, in consideration of the following mutual agreements and covenants and other good and valuable consideration, the sufficiency

 1.    Term of
Agreement. This Agreement (the “Term”) begins on July 1, 2021 and ends on the date the Executive terminates or resigns employment with the Company or any Subsidiary. 

2.    Severance Payment. Subject to the Company’s receipt of an effective Release of Claims executed by
Executive in the form appended hereto as Appendix A (“Release”), if Executive’s employment is involuntarily terminated by the Company without Cause (as defined herein), or by the Executive for Good Reason (as defined herein), but
excluding termination of employment due to Executive’s death or Complete Disability (as defined herein), Executive will be entitled to receive a “Severance Payment” consisting of:

	 	(A)	 Executive’s annual base salary at the time of termination; plus 

 

	 	(B)	 Executive’s target annual bonus under the Company’s Annual Incentive Plan. 

Any payment under this paragraph will be subject to all applicable payroll taxes and other withholdings and will not be included in earnings or compensation

contribution plan calculation, post-employment benefit calculation, or 401(k) calculation, unless such employee benefit plans or programs expressly provide for the inclusion of such amounts in earnings or compensation. 

The Severance Payment will be payable in a lump sum within 30 days of the Effective Date of the Release.

	 	g.	 other intentional activity, including but not limited to a breach of the Executive’s fiduciary duties with
respect to the Company, a Subsidiary, or any welfare plan or pension plan sponsored by the Company or a Subsidiary;

 SEVERANCE AGREEMENT 

 

 5.    Complete Disability or Death. If the Company
terminates Executive’s employment as a result of Executive’s Complete Disability, or if Executive’s employment is terminated due to the death of Executive, then Executive will not be entitled to receive the Severance Payment under
this Agreement. “Complete Disability” means Executive is prevented from performing their employment duties by reason of any physical or mental incapacity that results in Executive’s satisfaction of all requirements
necessary to receive benefits under the Company’s long-term disability plan. 
 6.    No Employment
Contract. This Agreement will not be deemed to constitute a contract of employment for any specific term or period. Notwithstanding any other provision of this Agreement, Executive’s employment with the Company remains at all times at-will and may be terminated by either party at any time, with or without cause. 

7.    Non-Duplication of Severance Benefits. If Executive
experiences a Qualifying Termination resulting from a Change-in-Control for which Executive is entitled to Severance Benefits under Executive’s CHANGE-IN-CONTROL SEVERANCE AGREEMENT, Executive will not be entitled to a Severance Payment under this Agreement. The benefits received by an Executive under the
Executive’s CHANGE-IN-CONTROL SEVERANCE AGREEMENT supersede and are in lieu of any Severance Payment to which the Executive may be otherwise entitled under this
Agreement. With the exception of the CHANGE-IN-CONTROL SEVERANCE AGREEMENT, this Agreement supersedes and replaces all prior severance agreements and similar agreements
between the Executive and the Company or any of its Subsidiaries (“Prior Agreements”). Any and all Prior Agreements other than the CHANGE-IN-CONTROL SEVERANCE
AGREEMENT cease to be of force and effect as of the Effective Date. 
 8.    Entire Agreement. Except as
otherwise provided in Section 7 above, this Agreement contains the entire agreement between Executive and the Company regarding the subject matter hereof and, as such, fully supersedes any and all prior agreements or understandings, whether
oral or written, between Executive and the Company pertaining to the subject matter addressed in this Agreement. To the extent any term or condition of this Agreement conflicts with any term or condition of any other agreement between the parties,
whether written or oral, this Agreement will prevail. 
 9.    Modification of Agreement. This Agreement
may be modified, amended or superseded only by a written agreement signed by Executive and the General Counsel of the Company. 

10.    Validity. If any provision of this Agreement or the application of any provision to any person or
circumstances is held invalid, unenforceable or otherwise illegal by a court of competent jurisdiction, the remainder of this Agreement and the application of the provision to any other person or circumstances will not be affected. The provision
held to be invalid, unenforceable or otherwise illegal will be amended to the minimum extent necessary to make it enforceable, valid or legal. 

11.    Choice of Law. This Agreement will be governed by and construed in accordance with the substantive
laws of the State of Michigan without giving effect to any choice-of-law rules that may require the application of the laws of another jurisdiction. 

12.    Internal Revenue Code Section 409A. All amounts payable under this Agreement are
intended to comply with the Code Section 409A “short term deferral” exception specified in Treas. Reg. § 1.409A-1(b)(4) or the “separation pay plan” exception specified in

Treas. Reg. § 1.409A-1(b)(9), or both of them, and shall be interpreted in a manner consistent with the applicable exceptions. If any amounts payable
under this Agreement do not qualify for an exception and are subject to Code Section 409A, this Agreement shall be interpreted and administered to comply with Code Section 409A to the maximum extent possible. Payment of any amount subject
to Code Section 409A that is scheduled to be paid within six (6) months after the Executive separation from service will accrue without interest and be paid on the earlier of (a) the first business day after the end of the six-month period, or (b) fifteen (15) days after the appointment of the personal representative or executor of Executive’s estate following his death. Nothing in this Agreement shall be construed as a
guarantee of any particular tax treatment. In no event whatsoever (including, but not limited to, as a result of this Section or otherwise) shall the Company be liable for any tax, interest or penalties that may be imposed on Executive under Code
Section 409A. “Termination of employment,” “resignation” or words of similar import, as used in this Agreement shall mean, with respect to any payments subject to Code Section 409A, the Executive’s “separation
from service” as defined by Code Section 409A. If any payment subject to Code Section 409A is contingent on the delivery of a release by the Executive and could occur in either of two years, the payment will occur in the later year.

 13.    Arbitration. Any controversy or claim arising out of or relating to this Agreement, its terms,
breach of any warranty or representation herein, or to interpret or enforce this Agreement, will be submitted to arbitration through the American Arbitration Association (“AAA”), with arbitration to occur in Wayne County, Michigan, and be
resolved in accordance with the rules then in effect for such entity. The arbitration proceeding will allow the parties to be represented by counsel at their respective expense, reasonable discovery, a hearing on the claim, selection of a neutral
arbitrator by mutual agreement, and if the parties are unable to agree, based on procedures provided by AAA, governing voluntary labor arbitration, judicial review as provided by Michigan law, and a written award containing findings of fact and
conclusions of law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. 

14.    Successors and Binding Agreement. This Agreement will inure to the benefit of and be enforceable by

this Release. 
 8.     Severability. In the event that any provision or any portion of any provision

all claims, liens, Medicare conditional payments and rights to payment, known or unknown, arising from any and all charges for medical treatment Executive has received or will receive in the future. If any governmental entity, or anyone acting on
behalf of any governmental entity, seeks reimbursement or damages (including multiple damages) from Company relating to Executive’s alleged past or future medical expenses, injuries, or claims, Executive will defend and indemnify Company, and
hold Company harmless from any and all such damages (including multiple damages), claims, liens, Medicare conditional payments and rights to payment, including any attorneys’ fees and costs sought by such entities. Executive agrees to waive any

Section 409A.
