Dear Ms. Karoly:
Enclosed is additional information requested to modify a
prior approved 401 Water Certification with Additional
Conditions, dated June 8, 2009 for the Pope Air Force Base
Ammunitions Supply Point, Cumberland County. The Division of
Water Quality (DWQ) Project # is 20081579; USACE Action ID. No.
2007-04036.
We understand some additional cumulative compensatory
wetland mitigation is required for this project due to some
unforeseen impacts. The compensatory mitigation plan will be
through the North Carolina Ecosystem Enhancement Program In-Lieu
Fee Program. As per communication between Mr. Ian McMillan and
Mr. Erich Hoffman by telephone on 10 June 2010, an error was
discussed pertaining to the North Carolina Department of
Environment and Natural Resources, DWQ letter dated June 3,
2010. The total amount of acres of compensator wetland
mitigation required for this project was stated incorrectly as
0.1414 acres. This total accidentally included some temporary
project impacts. The corrected total project impacts that
requires compensatory mitigation is 0.0834 acres.
The only additional cumulative area of permanent wetland
impact was caused by the construction expansion of the entrance
way off Vass Road to accommodate a required turning lane for
traffic. This lane was required due to traffic safety
requirements. See Plate CE-110. The permanent fill impacted
approximately 0.04172 acres of riparian wetlands. This impact
will be mitigated at a 2:1. The areas adjacent to the impacted
wetland will be graded stabilized and revegetated with the
appropriate approved Fort Bragg seed mix. Note: This area was

-2-
never delineated under the original wetland survey for
jurisdiction wetlands because the turning lane is outside of
what was considered the original Pope/Fort Bragg ASP boundary.
The contractor was unaware wetlands occurred north of Vass Road.
The second additional cumulative temporary wetland impact was
caused by a temporary road construction crossing that included a
culvert placed in a wetland area. These impacts and specifics
were addressed in a letter dated May 10, 2010. See Plate CE-
130. Since these cumulative impacts are temporary they will not
require compensatory mitigation.
If you have any further questions, please contact Mr. Erich
Hoffman at [phone] or [e-mail].
Sincere
Gregory G. Bean
Director of Public works
