Compressor Turbines NOTICE 30-00077E: Texas Eastern Transmission LP (258 Bristoria Road, Wind Ridge, PA 15380) Notice is hereby given in accordance with 25 PA Code 88 127.44-46 that the Department of Environmental Protection (Department) intends to issue Air Quality Plan Approval 30-00077E for installation of two (2) Solar, 10,744 HP, Taurus 070 natural gas-fired ocompressor turbines at the Holbrook Compressor Station located in Richhill Township, Greene County. These new turbines will replace twelve (12) engines. The turbines will be built with SOLONOX dry low NOx (DLN) technology for the control of NOx and equipped with oxidation catalysts for the control of CO, VOCS, and organic hazardous air pollutants (HAPS). The new turbines will be equipped with Solar Turbines proprietary gas release control technology to reduce the VOC and methane emissions associated with compressor turbine operations such as gas releases from dry seals and depressurization required for scheduled maintenance or non-emergency shutdowns. The facility is also replacing two emergency generators (Source IDs 120 and 121) with a Waukesha VGF24GL 585 hp, natural gas, emergency generator. The project will also include the installation of two (2) fuel gas heaters, each rated at 0.769 MMBtu/hr heat input, three (3) separator vessels each rated less than 450 galons used to collect pipeline liquids, and one (1) 2,940 gallon pipeline liquids tank. Potential to emit from the facility after installation of the new sources and controls will be: Table 1: Facility Wide Potential to Emit Air Contaminant Emission Rate(tpy) Nitrogen Oxides (NOx) 140 Carbon Monoxide (CO) 130 Total Particulate Matter (PM) 17 Particulate Matter Less Than 10 Microns In Diameter (PM10) 17 Particulate Matter Less Than 2.5 17 Microns In Diameter (PM2.5) Sulfur Oxides (SOx) 35 Volatile Organic Compounds (VOC) 62 Hazardous Air Pollutants (HAP) Formaldehyde (HCHO) 3.5 Carbon Dioxide Equivalents (CO2e) 325,000 The authorization is subject to State regulations including 25 Pa. Code $123.1, $123.2. $123.31, and $123.41, Federal New Source Performance Standards including 40 CFR Part 60 Subpart KKKK-Standards of Performance for Stationary Combustion Turbines and 40 CFR Part 60 Subpart JJJI-Standards of Performance for Stationary Spark Ignition Internal Combustion Engines, and National Emission Standards for Hazardous Air Pollutants from 40 CFR Part 63 Subpart ZZzz - National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines (RICE). This plan Approval has been conditioned to ensure compliance with all applicable rules. This includes emissions restrictions, operational restrictions, testing, monitoring. recordkeeping, reporting, and work practice requirements. The Department has determined that the proposed facility satisfies Best Available Technology ("BAT") requirements. Once compliance with the Plan Approval is demonstrated, the applicant will be required to revise or submit a Title V Operating Permit in accordance with 25 Pa. Code Subchapter G. The Plan Approval Application, the Department's Air Quality Review Memorandum, and the proposed Air Quality Plan Approval for this project are available for review by any interested party at the Department's Southwest Regional Office, 400 Waterfront Drive, Pittsburgh, PA 15222. A file review can be scheduled through the DEP's website at https://www.dep.pa.gov/Citizens/PublicRecords/Pages/Informal-File-Review.aspx. A person may oppose the proposed plan approval by filing a written protest with the Department through Melissa Jativa, Pennsylvania Department of Environmental Protection, 400 Waterfront Drive, Pittsburgh, PA, 15222; mjativa@pa.gov; or fax 412.442.4194. Each protest or set of written comments must contain the name, address and telephone number of the person submitting the comments, identification of the proposed Plan Approval (PA-30-00077E), and a concise statement of the objections to the plan approval issuance and the relevant facts upon which the objections are based. A public hearing may be held, if the Department, in its discretion, decides that such a hearing is warranted based on the information received. All persons submitting comments or requesting a hearing will be notified of the decision to hold a hearing by publication in the newspaper or by the Pennsylvania Bulletin, or by telephone or email, where the Department determines such notification is sufficient. Written comments or requests for a public hearing should be directed to Edward F. Orris, Environmental Engineer Manager, Pennsylvania Department of Environmental Protection, 400 Waterfront Drive, Pittsburgh, PA 15222 or by email to eorrisa pa gov. All comments must be received prior to the elose of business 30 days after the date of this publication. 3-16,17,18 Compressor Turbines NOTICE 30-00077E: Texas Eastern Transmission LP (258 Bristoria Road, Wind Ridge, PA 15380) Notice is hereby given in accordance with 25 PA Code 88 127.44-46 that the Department of Environmental Protection (Department) intends to issue Air Quality Plan Approval 30-00077E for installation of two (2) Solar, 10,744 HP, Taurus 070 natural gas-fired ocompressor turbines at the Holbrook Compressor Station located in Richhill Township, Greene County.
