Town of Elm City
Elm City Wastewater System Improvements
Qualitative Indirect and Cumulative Impact Analysis
WilsonCounty, North Carolina
The Town of Elm City has been under a sewer moratorium since 1998 which has
limited potential economic growth in the Town. The existing wastewater treatment
system currently exceeds the permitted flow on a regular basis and needs additional
capacity to meet both current demands and potential demands contributed to future
growth. The proposed project will provide that additional capacity allowing the Town
to adequately meet current needs and allow for future service expansion.
No cumulative effects are anticipated for groundwater resources as a result of the
proposedproject. Reduction of the public water supply is not anticipated from future
domesticconsumption and commercial usage.Cumulative impacts to surface
waters within the watershed may include sedimentation and run off from land
clearing activitiesand stream and wetland crossingsassociated with new
development, however, these impacts should be mitigated by utilizing best
management practices and limiting ground disturbance to the minimum practical.
All futureimpacts to surface waters and stormwater for construction of potential
projectsshouldbepermitted through proper State and Federal Agencies. Any
increased stream sedimentation andsoil erosion from increased land clearing for
future development should also be regulated throughState and Federal permitting
processes. Changes in hydrological regimes of streams and rivers within the
watershed isnot anticipated.
TheUt to UtTown Creekwithinthe proposed project area is not classified by the
North Carolina Department of Environmental Quality (NCDEQ). The receiving Town
Creek is classifiedas C;NSW. Class C waters are protected for uses such as
secondary recreation, fishing, wildlife, fish consumption, aquatic life including
propagation, survival and maintenance of biological integrity, and agriculture.
Secondary recreation includes wading, boating, and other uses involving human
body contact with water where such activities take place in an infrequent,
unorganized, or incidental manner.Nutrient SensitiveWaters (NSW)is a
supplemental classification intended for waters needing additional nutrient
management due to being subject to excessive growth of microscopic or
macroscopic vegetation.In addition, the proposed project watershedis within the
Tar-Pamlico River Basin which carries the Nutrient Sensitive Waters Management
Strategy: Protection and Maintenance of Existing Riparian Buffers.The purpose of
this Rule isto maintain and protect existing riparian buffers in the Tar-Pamlico River
Basin to maintain their nutrient removal functions.
Theexisting bufferrulesand the required Erosion and Sedimentation Control Plan
in accordance with rules established by the NC Sedimentation Control Commission
should reduce or eliminate the need for additional regulatory measures. Strict

adherence to these regulatory programs should result in the protection of the
watershed during growth in the surrounding area.
