Restoration Plan
Piedmont Natural Gas Line 99 Emergency Repair
Brunswick County, NC
The proposed project has been designed to avoid and minimize jurisdictional impacts where practicable. As
part of mitigation for unavoidable impacts, the following plan shall be implemented to restore temporarily-
affected wetlands. This plan entails restoration of temporarily-disturbed areas to their original contours and
conditions to the degree practicable upon project completion. Unless otherwise authorized by the
appropriate permits, no fills or spoils of any kind will be permanently placed within wetlands or along the
stream banks. Further, disturbed wetland areas will be permanently stabilized with native vegetative cover.
Proposed restoration activities will include the removal of placed fill material and restoration of original pre-
disturbance contours. Excavated material shall be returned to the trench to the extent possible, and
remaining excess material relocated and retained on an upland site. Excavated topsoil will be stockpiled
separately, kept viable, and then replaced uniformly over the area of excavation from which it was removed.
The native seed mix identified in Table 1 below will be utilized within temporarily-disturbed streambanks and
riparian buffer areas.

Wetland Seed Mix is to be applied to the disturbed wetland areas. The recommended application rate: 20 lbs.
per acre. To provide quicker cover, the mix specified in Table 1 should also be augmented with the
appropriate cover/companion species, as identified in Table 2.
Table 2: Cover/Companion Crops
Species Common Season Mix Notes:
Secale cereale Cereal or
Winter rye
Early Spring or
Fall 30 lbs/acre Grows 3-4' tall, but not a strong a
competitor.
Lolium perenne Perennial rye Early Fall or
Spring 15 lbs /acre Shorter rye; lasts about 2 years,
then dies out.
Urocloa ramose Brown Top
Millet Spring, Summer 15 lbs / acre Good germination; dies off with
frost; does not tolerate mowing.
Substitutions to the riparian and wetland mixes identified in this restoration plan may be made with prior
approval. Any substitutions shall consist of appropriate native species.
