FORM 144 AND SCHEDULE 13D AND 13G
The undersigned hereby constitutes and appoints Joel C. Lambert, Michael K. Post

substitution, as the undersigneds true and lawful attorney-in-fact to:
1.	Execute for and on behalf of the undersigned (a) any Form 3, Form 4 and Form

Securities Exchange Act of 1934, as amended (the "Exchange Act"), (b) Form 144
and (c) Schedule 13D and Schedule 13G (including amendments thereto) in
accordance with Sections 13(d) and 13(g) of the Exchange Act, but only to the
extent each form or schedule relates to the undersigneds beneficial ownership of
securities of Crestwood Equity Partners LP or any of its subsidiaries;
2.	Do and perform any and all acts for and on behalf of the undersigned that may
be necessary or desirable to complete and execute any Form 3, Form 4, Form 5,
Form 144, Schedule 13D or Schedule 13G (including amendments thereto) and timely
file the forms or schedules with the Securities and Exchange Commission and any
stock exchange or quotation system, self-regulatory association or any other
authority, and provide a copy as required by law or advisable to such persons as
the attorney-in-fact deems appropriate; and
3.	Take any other action in connection with the foregoing that, in the opinion
of the attorney-in-fact, may be of benefit to, in the best interest of or
legally required of the undersigned, it being understood that the documents
executed by the attorney-in-fact on behalf of the undersigned pursuant to this
Power of Attorney shall be in the form and shall contain the terms and
conditions as the attorney-in-fact may approve in the attorney-in-facts
discretion.
The undersigned hereby grants to the attorney-in-fact full power and authority
to do and perform all and every act requisite, necessary or proper to be done in
the exercise of any of the rights and powers herein granted, as fully to all
intents and purposes as the undersigned might or could do if personally present,
with full power of substitution or revocation, hereby ratifying and confirming
all that the attorney-in-fact shall lawfully do or cause to be done by virtue of
this Power of Attorney and the rights and powers granted herein.  The
undersigned acknowledges that the attorneys-in-fact, in serving in such capacity
at the request of the undersigned, are not assuming (nor is Crestwood Equity
Partners LP assuming) any of the undersigneds responsibilities to comply with
Section 16 of the Exchange Act.
The undersigned agrees that the attorney-in-fact may rely entirely on
information furnished orally or in writing by or at the direction of the
undersigned to the attorney-in-fact.  The undersigned also agrees to indemnify
and hold harmless Crestwood Equity Partners LP and the attorney-in-fact against
any losses, claims, damages or liabilities (or actions in these respects) that
arise out of or are based upon any untrue statements or omissions of necessary
facts in the information provided by or at the direction of the undersigned, or
upon the lack of timeliness in the delivery of information by or at the
direction of the undersigned, to the attorney-in fact for purposes of executing,
acknowledging, delivering or filing a Form 3, Form 4, Form 5, Form 144, Schedule
13D or Schedule 13G (including amendments thereto) and agrees to reimburse
Crestwood Equity Partners LP and the attorney-in-fact on demand for any legal or
other expenses reasonably incurred in connection with investigating or defending
against any such loss, claim, damage, liability or action.
This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form 3, Form 4, Form 5, Form 144,
Schedule 13D and Schedule 13G (including amendments thereto) with respect to the
undersigneds holdings of and transactions in securities issued by Crestwood
Equity Partners LP, unless earlier revoked by the undersigned in a signed
writing delivered to the attorney-in-fact.  This Power of Attorney does not
revoke any other power of attorney that the undersigned has previously granted.
IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the date written below.
