  1. What challenges are involved with rerouting the pipeline around/under Rt. 22?

    • This pipeline was originally constructed in 1947. In this day and age, there are many more regulations that impact how and where pipelines can be constructed. Environmental concerns involving creeks, wildlife and vegetation must be taken into account as well as the inconvenience to local residents. We want to make certain that our construction practices comply with all of those regulations.

  2. What are the minimum requirements regarding how close a pipeline can be to a home or other structure?

    • Applicable safety regulations would permit the installation of a pipeline as close as one foot away from a structure. Our Company's goal is to construct our pipeline as far away from housing as possible. Once the pipeline is constructed, new housing cannot be built within the permanent right-of-way. Landowners should let us know in advance if they require timber access roads or future driveway crossings so that we can incorporate these items into our pipeline design.

  3. How long do you monitor for crop loss? How is the crop value/reimbursement amount determined?

    • Crop yields are monitored for at least one year, possibly two years after construction has been completed. However, we will monitor three years or beyond to ensure pre-construction yield. (Crop yields are similar to adjacent undisturbed portions of the same field).

  4. Does the right to use eminent domain come from the state or from the FERC?

    • The right to use eminent domain comes from federal law. It is our goal to reach a mutual agreement with all affected landowners. We use eminent domain only as a last resort.

  5. Would Supply Corporation share its right of way (ROW) with another company?

    • Most 1947 ROW agreements allow for another pipeline within 16', parallel to the existing pipeline. We generally do not want another pipeline in our corridor. The new agreements we are pursuing are for one pipeline only.

  6. Will the existing Line N be abandoned?

    • The existing 20" pipeline will not be abandoned. Supply Corporation will be exploring potential uses for the line.

  7. In areas where Horizontal Directional Drilling (HDD) will be done, will you still need a 50 foot easement?

    • The Company still needs a right of way to operate the pipeline. However, in areas where HDD has been done, there are no restrictions on above ground structures or permanent crops.

  8. How will the operations of Markwest Energy affect this project? Will this pipeline transport gas for Markwest?

    • Line N is a part of the interstate pipeline system that transports natural gas that is ready for use in homes and businesses. Markwest is a producer/gatherer of natural gas that is not yet ready for home consumption; it must be processed before it comes into the interstate pipeline system. Therefore, Line N will not be transporting gas on its way to Markwest's processing facility. Line N may be used to transport gas that has been processed by Markwest.

  9. If there is already a 50' ROW through my property, will the new agreement be for another 50'?

    • The new agreement will specify a new 50' ROW, 25' of which will overlap the current ROW. In short, an added 25' will be needed.

  10. Will the new pipeline include anti-corrosion technology?

    • Yes, anticorrosion equipment will be installed.
