H i Ryan,
We are preparing to submit a buffer authorization for NCDOT's roadway project at PTI Airport for the Boom
manufacturing site (HE-0005). The project is expected to have no impacts to streams or wetlands, but there will be some
impacts to riparian buffers (see permit drawings attached). The project is located in the Jordan Lake watershed. We are
wondering whether DWR will categorize these impacts as either roadway or parallel impacts. Depending on how it is
categorized will tell us whether mitigation will be required.
If you can help us determine how to proceed, it would be much appreciated.
Thanks,
Nancy
