Good afternoon Ms. Munzer,
Thank you for your review of the Silas 100kV line project and my apologies it has taken me this long to get back to you.
There have been some changes to the project requiring additional coordination to address your and other permit review
comments. Those changes have been made and include the following items from your comments provided in August.
- The project proposes to install corrugated HDPE culverts. We have made a note to clarify that on the detail
drawings (See Detail A below). In addition please note that current issues in supply are preventing the use of
CMP or RCP culverts in this project.
- As per you recommendation, the list of species in the seeding schedule will be modify to the NC riparian mix.
(See Detail B Below.

Good morning Ms. Velasquez,
2

In reviewing the Silas 100 KV line project, I have a few comments. Due to concerns for aquatic passage, NCWRC would
prefer CMP or RCP instead of HDPE. However, if HDPE must be used, please use corrugated pipes.
Also, non-native plants should not be used for seeding disturbed areas. Specifically, avoid using Bermudagrass, redtop,
tall fescue, and lespedeza, which are invasive and/or non-native. A list of alternatives to non-native species has been
attached. Alternatively, use a grain, such as oats, wheat, or rye for temporary cover and native seed mixes for permeant
seeding. We recommend planting native, wildflower seed mixes that will create pollinator habitat within the project
boundary.
Thank you.
