On behalf of MPLX LP (the“Partnership”), the undersigned hereby requests, pursuant to Rule 461(a) promulgated under the Securities Act of 1933, that the Registration Statement on Form S-4 (File No. 333-206445) (the“Registration Statement”) of the Partnership be declared effective at 10:30 a.m. Eastern Time on Thursday, October 29, 2015, or as soon thereafter as practicable. The Partnership respectfully requests that you notify Kimberly J. Pustulka of such effectiveness by a telephone call to (216) 586-7002.
In connection with such request, the undersigned, on behalf of the Partnership, hereby acknowledges the following:
| • | should the Securities and Exchange Commission (the“Commission”) or the staff, acting pursuant to delegated authority, declare the Registration Statement effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement; |
| • | the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the Registration Statement effective, does not relieve the Partnership from its full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement; and |
| • | the Partnership may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. |
Please contact Kimberly J. Pustulka of Jones Day at (216) 586-7002 if you have any questions concerning this matter. Thank you for your continued attention to this matter.
