Re:	Red Cedar Gathering Company, Sambrito Compressor Station, Permit # SMNSR-SU-000049-2022.002, Proposed Synthetic Minor New Source Review Permit

Dear Mr. Powers:

The U.S. Environmental Protection Agency Region 8 (EPA) received a request from Red Cedar Gathering Company (Red Cedar), dated June 17, 2022, to revise the synthetic minor permit that the EPA issued pursuant to the Tribal Minor New Source Review (MNSR) Permit Program at 40 CFR part 49, for Sambrito Compressor Station (permit number SMNSR-SU-000049-2011.001). Red Cedar requested the following permit revisions; align the synthetic MNSR permit with the facility's applicable requirements of 40 CFR part 63, subpart ZZZZ, and its effective Title V operating permit; remove certain engine monitoring and corrective action requirements considered unnecessarily burdensome; would correct typographical errors. The proposed permit reflects some of the requested changes based on the EPA's evaluation.

We hereby issue the proposed revised synthetic MNSR permit for the Sambrito Compressor Station (permit number SMNSR-SU-000049-2022.002). 

The proposed permit and supporting materials are accessible for your review at https://www.epa.gov/caa-permitting/caa-permit-public-comment-opportunities-region-8 and Docket ID #EPA-R08-OAR-2022-0545 beginning April 6, 2023. The regulations at 40 CFR 49.157 and 49.158 require that the affected community and the public have the opportunity to submit comments on any proposed MNSR permit. All written comments submitted within 30 calendar days after the public notice is published will be considered by the EPA in making its final permit decisions. The public comment period will end at 5:00 p.m. MDT on May 5, 2023. 







If you have any questions concerning the proposed permit, please contact Lohitaksha (Lo.) Rao at (303) 312-6241 or at rao.lohitaksha@epa.gov.

							Sincerely,
