Shaun,
The Division received the courtesy copy of the subject PCN. I have attached to this email 401 Water Quality Certification
(WQC) 4133 (GC 4133), which corresponds to Nationwide Permit 12 (Utility Line Activities). The second page of the
attached document lists a number of thresholds or circumstances under which written approval for a 401 WQC is
required.
Please clarify the following items:
1. The stream impact table lists two stream impacts. However, there appears to be three stream crossings
associated with the project (Line "A" STA 19+00, 20+80, and 28+80.) Please clarify the discrepancy.
2. Please confirm Line "A" STA 29+00 to 30+50 will meet Condition 1.2. of GC 4133.
3. Please confirm the apparent stream crossing at Line "A" STA 28+80 will meet Condition 1.3. of GC4133.
Note that the stream impact table lists the impacts as permanent. As noted in a previous email, if the streambanks are
returned to near their original contour, seeded, and matted, as apparently depicted in the COIR MATTING STANDARD
DETAIL on Sheet D-3, the impact would be considered temporary. Future submittals should note impacts of this nature
as temporary.
Thanks and feel free to contact me if you have any questions.
