Planning and Permitting Services for Natural Gas Development

Geotechnical and air quality permitting to support cryogenic facility construction and operations.
  • Cryogenic processing facility aerial view - Gannett Fleming

    The facility's final capacity may reach 600 million cubic feet per day.

  • We coordinated the local road repairs and upgrades to handle additional loads into the new facility.

The client began construction in 2013 for a state-of-the-art cryogenic processing plant in Ohio to separate dry natural gas from natural-gas liquids (NGLs). The NGLs will travel through a 38-mile pipeline to another facility, where they will be converted to butane, ethane, and propane for homes and businesses. The plant will have the initial capacity to process up to 200 million cubic feet of natural gas per day. Two additional cryogenic plants are planned for the same site in the next several years. Final capacity may reach 600 million cubic feet per day.

Gannett Fleming’s work began with performing a geotechnical investigation of the site and zoning reconnaissance, and then expanded into full site design, roadway investigations, geotechnical investigations for horizontal directional drilling of pipelines, bridge inspections, building permitting assistance and inspection, on-lot sanitary sewer design, and air permitting.

What We Did

Gannett Fleming completed the air quality permit application to allow construction of a new natural gas processing plant to service production in the Marcellus and Utica Shales. The Ohio Environmental Protection Agency (EPA) Air Pollution Permit-to-Install and Operate (PTIO), allows installation, modification, and operation of emissions units at the plant. We pushed a fast-track schedule from an initial meeting in mid-January to obtain administrative completeness on the submitted application before the end of February. Tasks included calculation of maximum theoretical emissions and potential to emit; federal and state regulatory reviews, including New Source Performance Standards for natural gas processing (Subparts OOOO and VVa); and online form completion using the Ohio EPA's eBusiness Center. 

Our firm maintained close contact with the Ohio EPA permit writer to answer questions and provide supplements in a timely fashion to move the permit toward finalization. The final permit was issued in early June to keep the project on schedule. Construction on two additional plants began in late 2014, and our firm will assist with those projects through 2017.
