David,
Please see the responses below:
1) The re -submitted PCN wetland impacts table does not note the permanent impacts to forested and shrub -shrub
wetlands by conversion to herbaceous wetlands within the permanently maintained corridor along the utility right of
way. Please revise and resubmit this table noting in the comment section that approximately 0.5 acres of wetlands will
be permanently impacted due to conversion for the establishment of a 10 -ft wide permanent maintenance corridor.
Please see the attached/revised impacts table for the project. I apologize for prior confusion regarding this information.
2) The applicant is proposing broad impacts to WoUS for this project. Provide an analysis of alternatives to the proposed
sewer line alignment. This analysis should also include the feasibility of using alternative construction methods and
sewer line operation techniques in order to minimize impact to jurisdictional aquatic resources.
WGLA Engineering has prepared a memo addressing alternatives, which is attached for review.
3) The submitted documents do not note construction access points/corridors to the project area. Please submit
plans/maps locating these corridors and noting if impacts to WoUS will occur for these access features.
Please reference the figure included with the attached WGLA memo.
An updated impact map is also attached. Wetland Impacts #17 (W18), #18 (W19), and #19 (W21) were located in prior
converted cropland and have been removed from the impact map and impact table.
Please contact me if you have further questions or require any additional information.
Thanks,
Kaylie

Kaylie Yankura,
The Corps has received and reviewed your comments and documents per the Corps' request for additional information
dated March 26, 2018, for the Mud Creek Interceptor Sewer Line project in Hendersonville, Henderson County, NC. After
review and evaluation of the submitted documents, the Corps is requesting the following additional information.
1) The re -submitted PCN wetland impacts table does not note the permanent impacts to forested and shrub -shrub
wetlands by conversion to herbaceous wetlands within the permanently maintained corridor along the utility right of
way. Please revise and resubmit this table noting in the comment section that approximately 0.5 acres of wetlands will
be permanently impacted due to conversion for the establishment of a 10 -ft wide permanent maintenance corridor.
2) The applicant is proposing broad impacts to WoUS for this project. Provide an analysis of alternatives to the proposed
sewer line alignment. This analysis should also include the feasibility of using alternative construction methods and
sewer line operation techniques in order to minimize impact to jurisdictional aquatic resources.
3) The submitted documents do not note construction access points/corridors to the project area. Please submit
plans/maps locating these corridors and noting if impacts to WoUS will occur for these access features.
At this time, the request to utilize NWP 12 for authorization of impacts to WoUS is on hold until the above additional
information has been received. Once the Corps receives the information noted above we will be able to continue to
process your request. If you have any questions please contact me.
Sincerely,

RE: Mud Creek Sewer Extension
Project Clarifications
WGLA# 17100
DATE: May 31, 2018
We are in receipt of your email with additional questions from Mr. David Brown with the US Army
Corps of Engineers related to the Mud Creek Sewer Extension project. Below is a summary of the
questions and responses to each:
2) The applicant is proposing broad impacts to WoUS for this project. Provide an analysis of
alternatives to the proposed sewer line alignment. This analysis should also include the feasibility of
using alternative construction methods and sewer line operation techniques in order to minimize
impact to jurisdictional aquatic resources.
During the planning for the proposed Mud Creek project WGLA, Henderson County and Fletcher
Academy considered a number of alternatives to eliminating the Fletcher Academy wastewater
treatment facility and discharge. These alternatives considered construction of a new wastewater
treatment facility for Fletcher Academy. This alternative was eliminated due to environmental
considerations. A new treatment plant would continue to discharge to a zero flow stream.
Additionally, the cost for the operation and maintenance of the new treatment plant would place a
considerable financial burden on Fletcher Academy. Finally, this alternative would not allow
Henderson County to eliminate a major pump station in their system.
Another alterative considered was installation of a pump station and force main in lieu of a gravity
sewer line. Based on preliminary cost estimates, this alterative would be more expensive than a
gravity sewer line when considering operation and maintenance costs of both the new pump station
and the existing Naples pump station that will be eliminated. Further, this alternative did not follow
or further the County and Cane Creek's sewer system master plan for providing sewer service to
areas not currently served.
C I V I L E N G I N E E R S & L A N D P L A N N E R S
Ms. Kaylie Yankura
May 31, 2018
Page 2
The alternative of the gravity sewer option was selected since is was a better solution
environmentally considering it eliminated a wastewater discharge. It provided access to sewer along
the route and was in keeping with the County's sewer system master plan. Further, the gravity sewer
option was considered the best option from a financial standpoint when considering operation and
maintenance costs.
During the course of design, alternative routes, in some locations, as well as wider corridors were
delineated for streams and wetlands. The delineation provided information so that the sewer line
routing could be adjusted slight to avoid or minimize impacts. In many cases however, adjustment of
the line was not possible to avoid all impacts. Additionally, the alternative route around the Garren
property (see attached Figure 5) would have resulted in a greater impact to forest wetlands.
Related to alternative construction methods, boring through or under the wetland areas was
considered but eliminated from consideration due to costs. The cost for a gravity sewer bore is
approximately $400 — 500 per linear foot. The cost for excavation and installation of a gravity sewer
line is less than half the cost of a bore. Further, it is very difficult to install a bore at the minimal
grade necessary to support the gravity sewer option. For those reasons, the alternative of a bore for
the sewer line was eliminated.
3) The submitted documents do not note construction access points/corridors to the project area.
Please submit plans/maps locating these corridors and noting if impacts to WoUS will occur for these
access features.
Please find attached a copy of a plan showing construction access locations for the project. The access will be
from Rugby Road, US Hwy 25, Old Asheville Road, existing farm roads and from the Fletcher Academy
property. These access locations have been approved by NCDOT and Fletcher Academy.
If you have further questions or need more information, don't hesitate to contact our office.
