FINDING OF NO SIGNIFICANT IMVACT (FNSI)
Article I, Chapter 1 I3A of the North Carolina Gi,meral Statutes requires a project to be
subject to the requirements of the North Carolina Environmental Policy Act (NCEPA) if
it involves a major agency, action which will affect the environment. The proposed
project has been evaluated for compliance with the NCEPA and determined to be a major
action which will affect the environment and a State permit will be required.
Project Applicant: Water and Sewer Authority of Cabarrus County (WSACC)
Project Description: The proposed $6.7 million project is to be financed entirely
with local funds and no state loans or grants are involved.
The proposed Adams Creek interceptor system consists of
installing 34,500 114 8 to 30-inch pipes to serve the existing
development and the projected growth in the Adams Creek
drainage basin.
The review process indicated that significant adverse environmental impacts should not
occur if mitigative measures are implemented, and an environmental impact statement
(EIS) will not be required. The decision was based on information in the preliminary
engineering report and reviews by governmental agencies. An environmental assessment
supporting this action is attached. 't'his FNS1 completes the environmental review record,
which is available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least thirty days after
notification that the FNSI has been published in the North Carolina Environmental
Bulletin.
Sincerely,
Kerr T. Stevens, Director
Division of Water Quality
ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
Figures 1 and 2 identify the location of the proposed Phases I and II Adams Creek
collection/transport facilities.
Transport Facilities. The proposed project will be constructed in two phases to serve the
town of Mt. Pleasant and growth in the Adams Creek drainage basin. Phase I consists of
installing 15,500 l.f. of 30-inch gravity lines along Adams Creek. Three additional lines (5,200
l.f. of 8-inch, 4001.f. of 10-inch, and 1,500 I.f. of 30-inch gravity pipe) will be installed to
connect to the 30-inch pipe so that the existing Food Lion, Summer Street, and Pasture pump
stations can be eliminated. The Phase II project will consist of installing 11,600 l.f. of 24-inch
interceptor along Adams Creek to connect to the Phase I 30-inch gravity pipe listed above. An
additional 3001.f. of 8-inch pipe will be provided to connect to the 24-inch line so that the
existing Mt. Pleasant High School package treatment plant can be eliminated. In addition to
installing the proposed interceptors to eliminate an effluent discharge and overloaded pump
stations, the proposed collection/transport facilities will facilitate growth in the Adams Creek
drainage basin. The flow from the proposed interceptors will be discharged into an existing
pump station, and treatment will be provided by WSACC's treatment plant. A FNSI was
signed September 3, 1999 for the approval of the Rocky River regional treatment plant to be
upgraded and expanded from 24 to 34 mgd.
B. Existing Environment
Topography and Soils. The proposed project is situated in the Adams Creek drainage basin,
which is located in Cabarrus County. The topography is primarily rolling uplands with
elevations from 500 to 600 feet above mean sea level and slopes ranging from 1 to 40 percent.
Most of the upland soils are well drained with a clay or loam subsoil. Soils associated with the
streams and valleys are characterized by floodplain and wetland conditions. Septic tank
drainfields are primarily restricted due to impermeable soils in the Adams Creek drainage
basin.
Surface Water. Cabarrus County is located in the Yadkin-Pee Dee River Basin. Adams
Creek, a class "C" stream with a 7Q10 of 3.37 cfs, is the major stream in the project area.
Adams Creek drains into Dutch Buffalo Creek, which flows into the Rocky River. According
to water quality data, the supporting use of Adams Creek is threatened due to stream
degradation caused by growth and development in the area.
Water Supply. The town of Mt Pleasant receives its water supply from the Dutch Buffalo
Creek. Residents and commercial establishments that are not connected to the town's central
water system must rely upon groundwater.
C. Existing Wastewater Facilities
The town of Mt. Pleasant is located in two drainage basins: the Adams Creek basin to the west
and the Dutch Buffalo Creek basin in the east. All of the town's flow is treated at the 24 mgd
Rocky River regional wastewater treatment plant. Wastewater collected in the Adams Creek
basin is pumped to the Dutch Buffalo Creek basin via three submersible pump stations owned
by Mt Pleasant. An additional pump station, which serves the Mt. Pleasant Elementary School,
is also located in the Dutch Buffalo Creek basin. The Town has problems with overflows at the
two oldest pump stations (Summer Street and Pasture). Cabarrus County operates the 0.012
mgd package treatment plant which serves the Mt. Pleasant High School, and the effluent is
discharged into Adams Creek. The package plant is experiencing equipment problems, and
NPDES violations have been documented. Most of the town's collection system was installed
in the 1930's and the clay pipes with mortar joins are in poor condition. An infiltration and
inflow (I/1) analysis was performed and significant problems were documented. The town is
planning to implement a comprehensive sewer rehabilitation program.
D. Need for Proposed Facilities and Actions
The project area is experiencing a demand for residentiat development that is being driven by
the growth from the cities of Charlotte and Concord and Mecklenburg County. Accordingly,
the proposed interceptors will permit the collection of wastewater in the Adams Creek drainage
basin so that the flow can be conveyed efficiently to the Rocky River regional wastewater
treatment plant. The project will allow flows from the western portion of the town of Mt.
Pleasant to be collected by gravity, and, thus, eliminating three pump stations. The project will
also allow Cabarrus County to remove the effluent that is being discharged from the package
treatment plant serving the Mt. Pleasant High School. Therefore, the proposed project needs to
be constructed to provide the necessary collection/transport facilities to serve the existing and
future needs of the service area.
E. Alternatives Analysis
A facilities plan was prepared, and several choices were considered in the evaluation of
wastewater collection/transport facilities to serve the existing and future needs of the Adams
Creek drainage basin. The "no-action" alternative would require using individual septic tanks
to serve residential developments. However, the soils are not very conducive for utilizing
septic tank drainfields, and inadequately treated wastewater could cause public health problems
and degradation to surface waters. Package treatment plants are also not an acceptable
alternative because the individual treatment systems with surface discharges do not generally
function well enough to protect water quality. The "no-action" approach was rejected due to
the wastewater limitations of meeting long-term growth needs in the Adams Creek drainage
basin. The preferred choice of action is to provide the necessary collection/transport facilities
-2-
to convey efficiently the wastewater generated in the Adams Creek drainage basin to the Rocky
River regional wastewater treatment facility. It is the selected alternative.
F. Environmental Consequences, Mitigative Measures
The proposed 24 and 30-inch gravity interceptors will be installed primarily along Adams
Creek and in proximity to unnamed tributaries. The 8 to 15-inch connecting lines are to be
located perpendicular and away from streams. Approximately 85 percent of the sewer
corridors consist of alluvial forest with trees estimated to be thirty to forty years old. The
remaining sewer corridors include agricultural fields, pastureland, and residential yards. The
interceptors will be located in the floodplain, and numerous stream crossings will be required.
Some of the stream banks are deeply incised with steep to vertical banks. There are no
documented wetlands that will be impacted except the steam crossings, and all construction
activities will take place in accordance with the Corps of Engineers' Nationwide Permit
Number 12 and the Division of Water Quality's 401 Water Quality Certification. The
Department of Cultural Resources reviewed the proposed plan and determined that there were
no properties of architectural, historic, or archaeological significance which would be affected
by the project. The U.S. Fish and Wildlife Service and the N.C. Wildlife Resources
Commission evaluated the proposed project and requested that mitigative measures be
implemented to avoid or minimize adverse impacts associated with the construction and
operation of the proposed wastewater collection/transport facilities. All of the review
comments from the agencies are attached. Responses to the comments and mitigative measures
are provided to assure the project will be implemented in a manner to eliminate or minimize
adverse impacts to the environment.
G. Public Participation, Sources Consulted
A public hearing was held May 20, 1999 on the proposed project to install collection/transport
facilities in the Adams Creek drainage basin, which includes the town of Mt. Pleasant. The
hearing covered problems of the existing package treatment plant and pump station facilities,
need for the proposed improvements, and cost to implement the selected alternative. No
opposition to the proposed project has been expressed, and a resolution has been adopted to
implement the proposed project.
