Subject: REQUEST FOR ADDITIONAL INFORMATION
PNG Pleasant Garden Rd Looping Project
Dear Mr. Vena:
On April 8, 2019, the Division of Water Resources — Water Quality Programs (Division) received your
application dated April 4, 2019, requesting a 401 Water Quality Certification from the Division for your
project. The Division has determined that your application is incomplete and cannot be processed. The
application is on -hold until all of the following information is received:
1. The application documentation indicates that the permanent maintained easement is proposed
as 50 feet wide, however Condition 1.5 of 401 Water Quality General Certification #4133 states
that permanent maintained corridors for gas utility lines shall not exceed 30 feet wide. I do not
see that you have specifically requested an exemption to this Condition, so if that is your intent,
please clarify that in response to this request. Please note that PNG has previously requested
and been approved for 30 -foot permanent easements on multiple projects, therefore we would
need clear justification for why a greater maintenance corridor through wetlands and streams is
required for this specific line.
The plan view of the culvert replacement of AR -005 indicates that the proposed new culvert
alignment may have the potential to cause downstream erosion and water quality concerns as
the outlet appears to be within a sharp channel meander and outlet velocity would be directed
towards a stream bank. Please review this alignment in more detail and provide additional
information to support the current alignment, or realign the culvert outlet to better match the
natural stream channel alignment.
Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested
information for the proper consideration of the application. Please respond in writing within 30
calendar days of receipt of this letter by sending one (1) copy of all of the above requested information
