On February 15, 2022, the Division of Water Resources (Division) received your application requesting a 401 Water
Quality Certification from the Division for the subject project. On March 7, 2022, the Division received the required fee.
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:
• Section 1 (Information for Initial Review) of the PCN lists the nearest body of water as Mcdowell Branch, which is
incorrect. The stream in the project area is an unnamed tributary to Cartoogechaye Creek, which is a Class B,
Trout waters.
o You must contact Stan Aiken (copied) with DEMLR to discuss whether a Trout Buffer waiver will be
required for this project.
• Section 5 (Jurisdictional Determinations) of the PCN indicates that USACE issued a preliminary jurisdictional
determination. Please provide DWR with a copy of the PJD.
• As indicated under Item C.3.g (Page 13) of the USACE PCN Complete Help File "The stream impact length should
be measured along the centerline of the stream. When proposing a culvert, the impact length is generally
greater than the length of the culvert and associated dissipater since the existing stream usually has some
sinuosity (curvature)." Please verify or correct the stream impact length as indicated on the PCN form. Please
provide updated drawings and application materials (including Table of Impacts in the PCN form) that properly
show the length of impacts to the jurisdictional stream. [15A NCAC 02H .0502(a) and (c)](a)(9)
• The plan calls for a rip rap pad to be placed at the culvert outlet in the streambed. The Division considers this a
permanent impact. Please include this in the revised impact table.
• If the proposed precast end wall extends beyond the footprint of the proposed culvert, please update the
impact table to reflect this.
• In order to show your project will be in compliance with Condition II. 11 in GC 4263, please provide a detail
showing the proper installation (below the streambed elevation) of the riprap pad at the culvert outlet.
• Your response to Section E.1b (Avoidance and Minimization) states that "Phasing of work within stream and by
methods which minimize disturbance outside of the work area limits by use of sandbag dams and pumping if
required."
Per Condition II. 8 of GC 4263, all work must be done "in the dry". Therefore, dewatering methods will be
necessary to temporarily dewater the stream channel during pipe installation. Please ensure that the temporary
impacts are clearly indicated in the revised impact table.
i

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 provide your response by April 11, 2022. If all of the requested
information is not received, the Division will be unable to approve the application and it will be denied as incomplete.
The denial of this project will necessitate reapplication to the Division for approval, including a complete application
package and the appropriate fee.
