dept conservation and recreation comments
this is a pdf of comments submitted to FERC including various resources under their protection/development. also some of the endangered species and ecosystems they are concerned about.
There’s lots of information here about the entire length of the pipeline, with a special section for Buckingham..
These people might be amenable to looking at unknown resources, endangered species that you might know of and may not be referenced here.
The James River in Buckingham is a definite issue mentioned. I think organizations who protect the river need to receive this letter and become involved.
