D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
S&EC completed a wetland, stream and riparian buffer delineation for the proposed infrastructure project so that
the project engineers could design a plan to minimize impacts to the natural resources to the maximum extent
practicable. This delineation included evaluating the parcels of land directly south of the USACE property on the
east and west side of Wimberly Road for the proposed pump station. In addition, this delineation consisted of
evaluating a corridor 50' beyond the edge of pavement starting from the USACE property along the east and west side
of Wimberly Road and south to the Apex/Cary Water Treatment Plant. SBEC also evaluated an additional route
through the USACE property which followed the Colonial Pipeline Gas Easement.
The proposed infrastructure project, which consists of a pump station, a gravity sanitary sewer and water line
crossing White Oak Creek and a force main and water line going south along Wimberly Road will result in one
impact area (see sheets Exhibit 1-3) on USACE property. This proposed impact area consists of permanent and
temporary impacts to jurisdictional wetlands and riparian buffers associated with construction clearing, excavation
and the pits required for a Bore and Jack construction method. it's important to note that the construction easement
through the USACE property includes two different utilities and varies in width in order to minimize impacts to
wetlands and riparian buffers. It's also important to note that Town of Apex has agreed to a 10' wide permanent
maintenance corridor for each utility (i.e. sanitary sewer 8 water line) through the USACE property, therefore
permanent (i.e. conversion of wetlands from forested to herbaceous) impacts and future riparian buffer clearing for
this project have been minimized to the maximum extent practicable.
03-07-16- The Bore & Jack construction activities commenced and unanticipated flooding events of White
Oak Creek were encountered which resulted in stream a bank failure. These flood events determined the
need for dewatering the stream during the bore & jack construction activities. Therefore a temporary
stream bypass was put in place to create a safe work environment and sand bags were utilized to stabilize
the stream banks. Additionally, unexpected large debris (i.e. boulders, wooden timbers and tree stumps)
have been come across during the bore & jack construction activities. A temporary trench box was put in
place to control the work area and to minimize stream bank failures. All temporary stream and temporary
buffer impacts will be restored and stabilized once the construction activities have completed. A stream
bank stabilization plan will be submitted at a later date once the most appropriate plan is agreed upon by
the Town of Apex, the US Army Corps of Engineers and the NC Division of Water Resources.
in summary, the total updated impacts for this project are 0.024 acres of wetlands, 327 linear feet of stream,
6,233 W of Zone 1 and 3,482 ft' of Zone 2.
Furthermore, the applicant is aware of the regional conditions associated with the Nationwide Permits 12 With
respect to utility line activities (NWP 12 -Regional Conditions section 4.0), the applicant is proposing the Bore & Jack
method to minimize impacts to streams and wetlands, any temporary discharges into wetlands during construction
activities will be kept to minimum period of time and will be contained with appropriate erosion control methods,
construction corridor proposed to be 45 'wide because sanitary sewer and water line both to be constructed at the
same time within the same easement. utilities are not crossing the AIWW, the utilities are not aerial communication
lines, the cleared wetlands within the construction corridor will be re -vegetated with native species and the
permanently maintained corridor has been minimized to 10' wide with impacts less than 0.10 acres so mitigation
has not been proposed, use of riprap will not be necessary and construction area will be monitored for hydraulic
fracturing/hacking.
11b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Bore and Jack installation of the sewer line and the water line is being utilized. Sediment and Erosion Control methods
will be employed and enforced during construction and removed once the project is completed. Following construction.
grade will be returned to the original contours and planted with native wetland species. The Town will maintain only a 10'
maintenance corridor over the sewer and water lines.

constructed on USACE land. The
area of wetland disturbance, the size
and length of the water line, sewer
line. and pump station all fall under
the minimum criteria thresholds that
require NEPA/SEPA review The
USACE property office is reviewing
whether NEPAISEPA for the land
use permit for federal /aril will be
required.
1c. If you answered "yes" to the above, has the document review been finalized by the
❑ Yes ❑ No
Slate Clearing House? (If so, attach a copy of the NEPA or SEPA final approval
letter.) Comments:
2. Violations (DWQ Requirement)
2a. Is the site in violation of DWO Wetland Rules (15A NCAC 2H .0500), Isolated
❑ Yes ®No
Wetland Rules (15A NCAC 2H.1300), DWO Surface Water or Wetland Standards,
or Riparian Buffer Rules (15A NCAC 2B 0200)?
2b. Is this an after -the -fact permit application?
® Yes ❑ No
2c If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s) Permits were
pursued in 2014 and a Nationwide Permit 12 (A/D # SAW -2014-01522) and Water Quality Certification 3884 (DWR # 14-
0842) were both issued in August 2014 for this project. The Bore 8 Jack construction activities commenced and
encountered unanticipated flooding events of White Oak Creek which resulted in a stream bank failure. These
flood events determined the need for dewatering the stream during the bore 8 jack construction activities.
Therefore a temporary stream bypass was put in place to create a safe work environment and sand bags were
utilized to stabilize the stream banks. Additionally, unexpected large debris (i.e. boulders, wooden timbers and
tree stumps) have been come across during the bore 8 jack construction activities. A temporary trench box
was put in place to control the work area and to minimize stream bank failures.
3. Cumulative Impacts (DWQ Requirement)
3a. Will this project (based on past and reasonably anticipated future impacts) result in
® Yes ❑ No
additional development, which could impact nearby downstream water quality?
3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWO policy. If you answered "no," provide a short narrative description.
We have reviewed the "Draft Internal Policy, Cumulative impacts and the 401 Water Quality Certification and Isolated
Wetlands Programs" document prepared by the NC Division of Water Quality on April 10. 2004, version 2.1. The draft
states that "other pub/ically funded projects"may or may not result in cumulative impacts. The proposed White Oak
Creek Infrastructure project may result in future cumulative impacts however the Town of Apex has addressed these
potential secondary and cumulative impacts within their "Secondary and Cumulative Impacts Master Mitigation Plan' and
Biennial Reports found on the Town of Apex SC/ Master Mitigation Plan website: http //www. apexnc ora/servrcesiuubGc-
works/environmental-programs-division/scr-master-mitigation-plan. In addition to this plan and report, it is important to
note that the project is located within Town of Apex, therefore any proposed adjacent properties that have potential
for development would have the following regulations to protect downstream waters and water quality: 1 the Water

Supply, Watershed Protection Program which limits development densities as well as requires protective riparian
buffers, 2) the Jordan Watershed Basin Riparian Buffer Protection regulations, these regulations require limited
development within the riparian buffers, "diffuse flow"o/any concentrated stormwater which could require Best
Management Practices to control nitrogen and phosphorus if diffuse flow cannot be achieved: and finally 3) the
Phase Il NPDES Stormwater Permit Program, this program includes permitting requirements for Municipal
Separate Storm Sewer Systems (MS4s) in addition to post -construction stormwater management requirements.
We anticipate that the DWR will advise us if any additional information is necessary.
4.
Sewage Disposal (DWO Requirement)
4a
Clearly detail the ultimate treatment methods and disposition (non -discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility. This overall prgect is a proposed pump station, a sanitary
sewer going north and a force main going south. All wastewater from these new lines will ultimately connect to the Towns
treatments facility.

5d.
What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
S&EC performed a records search of all federally protected Endangered and Threatened species documented by the North
Carolina Natural Heritage Program (NHP) within a 2-mile radius of the evaluated area, all federally protected aquatic species
documented within the projects 14-digit HUC, and all federally protected species documented by the US Fish & Wildlife Service
(USFWS) to occur in Wake County, NC.
No occurrences of federally protected species are documented within the project site, no federally protected aquatic species are
documented by NH to occur in the project's HUC, and no federally protected species are documented by NHP to occur within 2
miles of the evaluated area.
In addition, a preliminary evaluation of potentially suitable habitat for federally protected species was performed by reviewing
available mapping including 2013 USGS quadrangles and 2013 aerial imagery. The preliminary review showed that potentially
suitable habitat for Michaux's Sumac. A target species survey for Michaux's Sumac and an on-site assessment of potentially
suitable habitat for federally protected species was performed by S&EC on June 10, 2014. Transects along the transition area
between managed herbaceous roadside and forested areas were walked in search of Michaux's Sumac, and M specimens wet
found. Several specimens of Winged Sumac (Rhus copallinum) were observed within the transitional area between
managed/herbaceous roadside and planted pine forest. No suitable habitat for any other federally protected species was
located within the evaluated area.

Will this project occur in or near an area that the state, federal or tribal
❑ Yes ®No
governments have designated as having historic or cultural preservation
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b.
What data sources did you use to determine whether your site would impact historic or archeological resources? A
review of online records maintained by the North Carolina State Historic Preservation Office (SHPO) was conducted in
June 2014. No historic structures are documented by SHPO within the evaluated area and during the site visit on
June 10. 2014, no structures or ruins were observed within the evaluated area In addition, a preliminary request for
comment regarding potential archaeological or cultural resources within the evaluated area was submitted electronically
to the State Office of Archaeology (OSA). Comments received indicated that the area had not previously been surveyed.
however. the evaluated area is not likely to contain any archaeological sites that would be eligible for the National
Register due to previous disturbance from the construction of Wimberly road.
