  1. What noise level is equivalent to 55 dBl?

    • 55 dBL is comparable to normal conversation.
  2. Will there be an increase in the noise level at the Marc West metering station?

    • This is a non-regulated gathering facility. The amount of gas going through this station will increase; the noise level may increase due to the increased pressure in the pipeline. We will look into this to determine the overall effect and if any improvements can be made
  3. For the compressor station, what will be done to mitigate the noise level?

    • Various noise treatment options will be implemented, including 6-8 inches of insulation inside the building; interior liner to the building itself; special ventilation systems; silencer on intake and exhaust; low speed fans with special fan blades on coolers; pipes buried where possible; sound-proofed auxiliary equipment enclosures. All noise sources receive a technical acoustic evaluation and are treated to minimize impact as necessary..
  4. Will a revised noise report be submitted to the Township?

    • Yes. A current, revised report will be submitted.
  5. How high will the roofline of the compressor building be?

    • 28 feet is the highest roofline in our system; Buffalo Station will be lower. Exact height will be determined as we get further into the design process.
  6. How far from the existing pipeline will the new pipeline be?

    • The new section of pipeline will be approximately 25 feet from the existing line. We plan to stay within or parallel to the existing easement, but may require additional ROW.
  7. What will be the maximum operating pressure of the new line?

    • The current line has a maximum operating pressure of 787 psi, and typically operates below 600 psig. The new line will also operate within that range.
  8. Is the gas to be transported wet or dry gas?

    • This is dry gas.
  9. What about venting operations? How much noise will there be?

    • Normal venting operations will be silenced to the same specs as the rest of the station. Only the emergency shut-down vents are not silenced.
  10. How is this station going to be monitored? Where would someone come from in the event of an emergency?

    • The station will be monitored by our Gas Control Operations in New York. We do plan to hire someone in this area once everything is up and running.
  11. Will the fire department be trained to handle an emergency?

    • We will meet with all emergency responders to make sure they are familiar with the station, its safety features and know who to contact in the event of an emergency. Meetings with local emergency personnel are conducted on a regular basis.
  12. Why is the proposed line located to the right (east) of the existing line? Why not to the left?

    • This was the preliminary location. However, the route will be finalized after a review of all survey information and upon FERC approval and discussion with the landowners.
  13. Do you need the existing pipeline? Why not use the same footprint for the new one?

    • The existing line may prove useful as a future gathering system line as local natural gas production ramps up.
  14. If we now have a 50 ft. ROW, how much more will you need?

    • In most areas, we will need an additional 25 ft. of permanent ROW.
  15. How will compensation be determined?

    • Company representatives will meet with each affected landowner to discuss compensation. Local appraisers will be used to determine property values.
  16. What affect will ROW clearing have on current "Clean and Green" status? 10% marketable lumber is required.

    • There are three eligible Clean and Green Assessment classifications - Agricultural (farmland); Forest Reserve (forested land); and Agricultural Reserve (open space land). According to the Washington County Assessor's Office, the installation of a pipeline will not change the use of the land, which is the most important condition of a Clean and Green Assessment. Even if a right-of-way corridor of timber is removed on a Forest Reserve classified parcel, it should not affect the Clean and Green assessment.
  17. What about existing fencing?

    • We will replace all existing fences, gates and other items disturbed by our construction activities. Any temporary livestock fencing issues required during construction can be discussed during the right of way negotiations.
