The primary route filed with FERC in March 2015 reflected the project alignment as of Dec. 1, 2014. The supplemental filing today incorporates additional minor route changes adopted between Dec. 2, 2014 and March 31, 2015. Another supplemental filing reflecting changes made after March 31, 2015, will likely be submitted to FERC in July 2015.

Today’s supplemental filing incorporates an additional 40 minor route adjustments and workspace changes affecting roughly 10% (18.68 miles) of the total greenfield pipeline project, increasing the total greenfield mileage by 1.4 miles to 183.7 miles. These changes are primarily the result of requests from landowners and public officials, as well as attempts by project planners to further avoid various sensitive resources and land uses.

About half of the changes (21) were routes which had been previously identified as alternatives in the March 2015 FERC filing. The most significant of these included Alternate Route 17 (1.3 miles in Lebanon County), Alternate Route 19 (1.2 miles in Schuylkill County) and Alternate Route 20 (0.8 miles in Columbia County).

A complete list of the route modifications can be found in Table 1 (page 4-5) of Volume 1, supplemental filing part 1.

To date Williams has made adjustments to more than 50% of the greenfield pipeline route since it was introduced last year.
