Leonard Production Facility - Weld County Notice Period Begins: November 29, 2018 Notice is hereby given that an application for a proposed project or activity has been submitted to the Colorado Air Pollution Control Division for the following source of air pollution: Applicant: Extraction Oil Et Gas, Inc. Facility: Leonard Production Facility Well Production Facility NWSW of Section 21, Township 2N, Range 67W Weld County The proposed project or activity is as follows: The operator is requesting permit coverage for eight (8) 400 barrel fixed roof condensate storage vessels,natural gas venting from one (1) heater treater, one (1) gas buster and eight (8) three-phase high-low pressure separators, two (2) 400 barrel fixed roof produced water storage vessels, and condensate loadout. These emissions sources are located at a new oil and gas well production facility located in the ozone non-attainment area. The Division has determined that this permitting action is subject to public comment per Colorado Regulation No. 3, Part B, Section III.C due to the following reason(s): • permitted emissions exceed public notice threshold values in Regulation No. 3, Part B, Section IIl.C.1.a (25 tpy in a non-attainment area and/or 50 tpy in an attainment area) • the source is requesting a federally enforceable limit on the potential to emit in order to avoid other requirements The Division has made a preliminary determination of approval of the application. A copy of the application, the Division's analysis, and a draft of Construction Permit 18WE0215, 18WE0216, 18WE0217, 18WE0218 Et 18WE1092 have been filed with the Weld County Clerk's office. A copy of the draft permit and the Division's analysis are available on the Division's website at https://www.colorado.gov/pacific/cdphe/air-permit-public-notices The Division hereby solicits submission of public comment from any interested person concerning the ability of the proposed project or activity to comply with the applicable standards and regulations of the Commission.
