1.0 PURPOSE AND NEED FOR PROJECT
OW4
1.1. Project Description
The Town of Mocksville owns and operates two wastewater treatment facilities: the
Dutchmans Creek Facility (NC 0021491), and the Bear Creek Facility (NC 0050903). See
Ptl Figure 1, Figure 2 and Figure 3 in Appendix I for vicinity maps for these two facilities.
Bear Creek is a small stream with a 7-day 10-year low flow (7Q10) of approximately 0.675
mgd. The Town's 0.250 mgd oxidation ditch type treatment facility discharges into Bear
Creek. The average daily discharge in 2002 through the plant was 0.184 mgd while the
average daily discharge in 2003 through the plant was 0.262 mgd. The higher 2003
discharge appears to have resulted from Inflow and Infiltration resulting from greater rainfall
in that year. The NCDENR has required the Town to address flow issues at the Bear Creek
Treatment Plant.
M
Dutchmans Creek is a somewhat larger stream with a 7Q10 of 9.69 mgd. The Town owns
and operates a 0.680 mgd extended aeration treatment plant discharging to Dutchmans
rAq Creek. The average daily discharge in 2002 through the plant was 0.504 mgd while the
average daily discharge in 2003 through the plant was 0.567 mgd. As was the case for the
Bear Creek facility, the higher 2003 discharge appears to have resulted from inflow and
infiltration resulting from greater rainfall in that year.
The Town of Mocksville has instituted an ongoing rehabilitation program to address the Inflow
aq and Infiltration issues with both the Bear Creek collection system and the Dutchmans Creek
collection system. As this program is independent of the upgrade project, it will not be
discussed at length in this report.
The Ingersoll-Rand Company discharges into the Bear Creek collection system. Since
Ingersoll performs machine fabrication and metal finishing, the company operates under a
categorical pretreatment permit and pretreats its wastewater to relatively high standards prior
to discharge. The company's pretreatment permit allows for discharging up to 65,000 gallons
per day through the pretreatment plant and 36,000 gallons per day from ground water
remediation wells on site. Ingersoll is seeking to add additional manufacturing capability.
However, since the Bear Creek WWTP is flow limited and Bear Creek itself is a small,
sensitive stream, moving the Ingersoll-Rand discharge to the Dutchmans Creek facility
provides an opportunity to reduce flows to Bear Creek and utilize the additional assimilative
capacity of Dutchmans Creek.
The Crestwood Farms Company (a poultry and pork cooking company) has asked for
additional treatment capacity to support its plant expansion. A new Wal-Mart complex is also
planned for the area. Crestwood Farms and the proposed Wal-Mart are directly tributary to
�' the Dutchmans Creek Treatment Plant.

The Bear Creek WWTP is an oxidation ditch type of facility constructed in 1983. The
Dutchmans Creek WWTP is an extended aeration facility initially constructed in 1970 and
expanded in 1983. The treatment facilities are in good condition and perform well. All sewer
rights of way are well maintained and mowed frequently.
The Town is well equipped to remediate the sewer system. The Town owns a sewer camera
and smoke testing machine and is in the process of purchasing additional flow monitoring
PON equipment for use in Inflow tracking and reduction. The Town also owns a full complement of
sewer cleaning and construction equipment.
mz' 1.2. Purpose and Need for Project
The Bear Creek Plant is currently operating beyond its permitted capacity and is discharging
r' to a small stream. The Ingersoll Rand Company requires additional capacity that the Bear
Creek Plant is unable to provide at present.
MCI The Crestwood Farms Company has requested additional capacity and discharges into the
Dutchmans Creek collection system. A new Wal-Mart facility is proposed and would also
discharge into the Dutchmans Creek collection system. The Dutchmans Creek WWTP is
n currently operating at 83% of its rated capacity. NCDENR requires approval of construction
drawings and a construction schedule when actual flow exceeds 90% of permitted plant
Mn capacity.
The Ingersoll Rand Company and Crestwood Farms International have both committed in
F, writing to provide additional jobs if these wastewater capacity issues are resolved.
The proposed improvements to the Town's wastewater treatment and collection system will
work in conjunction to provide for more efficient treatment of wastes, as well as provide for
present and future wastewater treatment capacity. In addition, the project will result in
providing for future economic development.
2.0 ALTERNATIVES TO THE PROPOSED ACTION
Alternative 1. Sewer Rehab for Inflow and Infiltration and no action for plant upgrade.
Inflow and infiltration are issues that are being addressed in the system. However, even in
dry conditions when Inflow and Infiltration are not a factor, the Bear Creek Plant is reaching
capacity and cannot handle a substantial flow increase from the Ingersoll Rand facility
because the receiving stream is fragile and flow limited.
`m-' Regardless of the status of the Bear Creek WWTP, the Dutchmans Creek WWTP must be
upgraded in order to provide for the projected needs from overall growth, the Crestwood
Farms expansion and proposed new development.
Alternative 2. Expansion of the Bear Creek Facility and the Dutchmans Creek Facility.
Expanding both facilities without moving the Ingersoll discharge will increase flow to a stream
PIP

that is receiving a wastewater load approximately 37% of its 7Q10. Regardless of
environmental issues, providing a pump station and force main for an estimated construction
cost of $160,000 is considerably less than providing a Bear Creek Treatment plant upgrade
to 350,000 gpd at an estimated cost of $500,000, while also upgrading the Dutchmans creek
plant at an estimated cost of $1,500,000.
Alternative 3. Transferring the Ingersoll Rand wastewater from the Bear Creek WWTP to the
`T' Dutchmans Creek WWTP and Expanding the Dutchmans Creek WWTP Facility.
This alternative is more fully developed and is recommended. The option includes a pump
station and force main to transfer the Ingersoll Rand wastewater and a 300,000-gallon
upgrade to the Dutchmans Creek treatment plant. Table 2.1 provides a preliminary cost
estimate for this option. The Dutchmans Creek treatment facility would be expanded
approximately 50% by the addition of a treatment module similar to the other modules, which
have performed well. Designs are in accordance with NCDENR and the Ten States
standards, at least 24 hours of hydraulic detention will be provided in the aeration basin with
2-25 hp aerators. Clarification, chlorination and disinfection will be provided as in previous
phases. Dechlorination will be provided.
a
Mq
Zal
This alternative will address the Town of Mocksville's long-term wastewater treatment
capacity needs as well as the impact on Bear Creek. This alternative has an estimated cost
of $1,685,000. The proposed expansion of the Dutchmans Creek WWTP will be conducted
within the confines of the existing property, thereby minimizing environmental disturbance.
The construction of the pump station will occur on the property owned by Ingersoll-Rand, and
the associated force main will be in the Town of Mocksville's street rights of way.

3.1. Land Use
3.1.1. General Land Use
The proposed Town of Mocksville Dutchmans Creek Wastewater Treatment Plant
Upgrade consists of expanding the hydraulic capacity of the Dutchmans Creek WWTP
from .680 mgd to .980 mgd, as well as the installation of a pump station and associated
�+ force main to transfer the categorical discharge from Ingersoll Rand from the Bear Creek
Basin to the Dutchmans Creek basin. The WWTP upgrade and expansion will occur at
the existing WWTP site, the pump station installation will occur at the Ingersoll Rand site
on Sanford Avenue with its associated force main being run to East Maple Avenue to tie
into the Dutchmans Creek collection system.
The Town of Mocksville and Davie County have zoning ordinances and land use plans.
The area immediately surrounding the existing Dutchmans Creek WWTP is zoned
Residential/Agricultural. The area surrounding the treatment plant is open field and

pasture. The site of the pump station installation is a large industrial property and the
0=4 associated force main will be installed in the Town of Mocksville's street rights of way.
The Town of Mocksville owns the property where the existing WWTP in located which is
an eight -acre tract off Garwood Road. However, due to the layout of the existing WWTP,
the Town will need to purchase three -fourths of an acre of land to accommodate this
upgrade. Ingersoll-Rand owns the property where the pump station will be installed
which is a one hundred thirty two -acre tract in the Town of Mocksville. The force main
will be run in the Town of Mocksville's street rights of way.
f' The proposed project will not directly result in changes in land use. Increased
wastewater treatment capacity, however, may result in increased commercial and
awl residential development in the system's service area.
3.1.2. Important Farmland, Prime Rangeland, and Forestland
'=' 3.1.2.1. Affected Environment
The proposed Town of Mocksville Dutchmans Creek WWTP Upgrade consists of two
project elements at two separate locations. The WWTP upgrade and expansion
element will be conducted at the site of the current WWTP. The site covers
approximately eight acres, with approximately two acres already developed. The
expansion is expected to result in approximately one acre being developed. Due to
the layout of the existing plant, the Town will need to purchase about three -fourths of
an acre of land to accommodate this upgrade. Soils on the site consist of Gaston
loam, Enon, Mecklenburg, and Chewacla soils. The site is owned by the Town of
Mocksville and is not currently used for agricultural or forestry purposes. Portions of
the Davie County Soil Survey are included as Figure 4 and Figure 5 in appendix I.
The proposed installation of the pump station will occur at the property owned by
Ingersoll-Rand and located on Sanford Avenue in Mocksville and will not disturb any
farmland, forest land or rangeland. The proposed force main will be installed in the
Town of Mocksville's street rights of way.

The proposed Town of Mocksville's Dutchmans Creek WWTP upgrade will
increase the systems wastewater treatment capacity, thereby allowing for future
development in the systems service area. The primary service area is in the Town
of Mocksville ETJ district, which is urbanized. Since locations of future
development (if any) are unknown, it is impossible to determine future impacts of
the proposed project on important farmland, prime forestland, or prime rangeland.
However, it should be noted that no additional service lines are included in this
project.

3.1.3.3. Mitigation
Since the proposed project will not have a direct impact on formally classified lands,
no mitigation measures are proposed.
3.2. Floodplains
3.2.1. Affected Environment
There are no detailed Federal Emergency Management Agency (FEMA) Flood Insurance
Rate Maps available for the sites in question. However a review of the generic maps
reveal a portion of the site where the WWTP is located is within the 100-year flood plain.
,a, However, the WWTP itself is located outside of the flood plain.
FR
pq
The proposed site of the new pump station is located within the Town of Mocksville, which
is not mapped by the FEMA program. However, a review of the appropriate USGS
topographic map (Mocksville Quadrangle circa 1969) indicated the flood plain to be at an
elevation of 725 feet approximately 1800 feet downstream from the pump station site.
The top of the pump station is at an elevation of 750. The installation of the force main,
however, will cross a small wet weather ditch tributary to Bear Creek.
The FEMA Flood Insurance Rate Maps covering the project are Community -Panel
Number 370308 0100 C. A portion of the FEMA Flood Insurance Rate Map is included as
Figure 6 in Appendix I.
There will be no land disturbance conducted within the floodplain. The improvements at
the WWTP and the installation of the force main will not result in any new development in
the floodplain.

There will be no direct impact of the Town of Mocksville's Dutchmans Creek WWTP
upgrade on floodplains. Therefore, a FEMA 81-93 Standard Flood Hazard
Determination Form is not included.
3.2.2.2. Indirect Impacts
The Town of Mocksville and Davie County both have ordinances in place which
prohibit development within the flood plain area. This project will create additional
wastewater treatment capacity for the Town, which could enable the extension of new
collection lines. Floodways could be crossed with transmission lines, but no other
r,
development would be permitted.
3.2.2.3. Cumulative Impacts
The cumulative impacts of the Town of Mocksville's Dutchmans Creek WWTP
upgrade on floodplains will be possible future installation of interceptor sewer mains.
3.2.3. Mitigation
To discourage new development in the floodplain the Town of Mocksville and Davie
County have ordinances prohibiting the construction of buildings in the floodplain.
To mitigate any impacts to water quality while construction activities are taking place,
the Town of Mocksville will employ appropriate sedimentation and erosion control
measures during construction of the project.
3.3. Wetlands
r, 3.3.1. Affected Environment
Based upon USDA—NRCS Soil Survey for Davie County the soil at the site of the
FM Dutchmans Creek WWTP is Gaston loam with Enon and Mecklenburg soils. A narrow
band of Chewacla loam exists along the bank of Dutchman Creek. The existing facilities
are located out of the floodplain, which contains the Chewacla soils. The proposed
RR expansion is also planned to be outside of the floodplain and Chewacla soil band. A site
visit was conducted by Grey Engineering to identify possible wetlands areas. No
identified wetlands areas will be impacted by the proposed Dutchmans Creek WWTP

with approximately two acres already developed. The expansion is expected to result in
approximately one acre being developed. The proposed pump station will occur on the
one hundred thirty two -acre tract owned by Ingersoll-Rand. Plans for the pump station
and associated force main were submitted to the NC Department of Cultural Resources'
State Historic Preservation Office (SHPO). Archeological resources were not identified
during previous construction phases in 1970 and 1983. With the close proximity of the
planned expansion to the existing structures, no archeological resources are anticipated.

In addition, due to the low level of new structures proposed at the WWTP and location
'� of the project in an isolated, low-lying area approximately four miles from the Town of
Mocksville, there will be no impacts to visual aesthetics.
Simi 3.4.3.1. Indirect Impacts

S, If any archaeological materials such as stone projectile points, ceramic shards, bricks, or
human skeletal remains are encountered prior to or during construction of this project,
activities will be ceased and the State Historic Preservation Office will be notified. The
Val contract for project construction (the EJCDC — Funding Agency Edition) will include this
requirement.
rl 3.5. Biological Resources
3.5.1. Affected Environment
The Town of Mocksville's Dutchmans Creek WWTP upgrade Project will result in
approximately one acre of land disturbance at the existing WWTP site. The WWTP
discharges directly into Dutchmans Creek.
Vegetation in the project area includes low-lying weeds and grasses. Wildlife in the area
includes whitetail deer, opossum, turkey, chipmunk, raccoon, and squirrel.
There are two species thought to exist in southern Davie County that are currently listed
as threatened or endangered under the Endangered Species Act of 1973 as amended
(see Appendix II for Table 1). They are the Bog Turtle (Glyptemys muhlenbergil), a
federally threatened species and Michaux's Sumac (Rhus michauxif), a federally
endangered low shrub. The Bog Turtle has not been seen in Davie County, but it is noted
here as suitable habitat in considered being available. Michaux's Sumac has been found
in northern Davie County. There is a sufficient amount of variation in habitat preference
that this species might occur in shrubby or wooded sites. No Michaux's Sumac has been
seen in southern Davie County but is noted here as it is the only federally listed species
that warrants attention.

The direct impacts of the project on biological resources will the be protection of water
quality and aquatic life in Bear Creek as a result of the reduced risk associated with
the re-routing of Ingersoll-Rand's categorical effluent. Requests were sent to the
North Carolina Wildlife Resources Commission as well as the North Carolina
Department of Environment and Natural Resources Division of Water Quality.
Correspondence from these agencies is included in Appendix II.
Mn 3.5.2.2. Indirect Impacts
Completion of the project will increase the Town's wastewater treatment capacity.
Pal This will allow for future growth in and around the Town of Mocksville. However,
future growth cannot be directly linked to the project, and is expected to occur
regardless of the project. Increased development could result in loss of wildlife
habitat. There are no known threatened or endangered species in that area of Davie
County.

r' 3.6. Water Quality Issues
3.6.1. Affected Environment
The Town of Mocksville's Dutchmans Creek WWTP upgrade is scheduled in part to
protect the water quality of both Dutchmans Creek and Bear Creek. The project consists
of redirecting the discharge from Ingersoll-Rand from the Bear Creek system to the
Dutchmans Creek system, and expanding the capacity of the Dutchmans Creek WWTP.
These improvements will protect water quality by reducing the risk in Bear Creek, which is
Mn a small and fragile ecosystem, and by increasing the treatment capacity of the Dutchmans
Creek WWTP, allowing it to use the larger assimilative capacity of Dutchmans Creek.
The majority of Dutchmans Creek in Davie County is classified as 'C' with the exception of
the source lake, which is classified as 'B' and the last nine -tenths miles prior to
discharging into the Yadkin River, which is classified as 'WS/IV'.
Class C waters are protected for secondary recreation, fishing, wildlife, fish and aquatic
r-M life propagation and survival, agricultural and other uses suitable for Class C. 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.
,m There are no restrictions on watershed development or types of discharges.
rwn
3.6.2. Environmental Consequences
3.6.2.1. Direct Impacts
Pq The direct impact of the Town of Mocksville's Dutchmans Creek WWTP upgrade will
be the protection of water quality in Bear Creek as a result of decreasing the risk of
the categorical effluent from Ingersoll-Rand to the Bear Creek WWTP. Currently Bear
Creek has a loading of 37% from the WWTP (based on a permitted flow of .250 mgd
and a 7Q10 of .675 mgd). The re-routing of the Ingersoll-Rand categorical effluent will
help to attenuate the risk to Bear Creek associated with this waste stream.
rMn
Dutchmans Creek is currently loaded at 7%(based on a permitted flow of .680 mgd
and a 7Q10 of 9.69 mgd). There will be an increase in the volume of effluent from the
Dutchmans Creek WWTP as a result of the expansion, a portion of which will be the
redirection of the Ingersoll-Rand flow. This will increase the loading in Dutchmans
Creek to 10%. The larger assimilative capacity of Dutchmans Creek will also serve to
attenuate the risk associated with the categorical effluent from Ingersoll-Rand.
The North Carolina Wildlife Resources Commission in response to the State Clearing
'� house raised a concern regarding possible toxicity issues with moving the Ingersoll-
Rand discharge from the Bear Creek basin to the Dutchmans Creek basin, specifically
problems associated with Dissolved Oxygen and Fecal Coliform. A review of the DMR
Op
OR

am
am
data for the past several years indicates no problems with either of these constituents.
P4 The North Carolina Wildlife Resources Commission also mentioned a toxicity problem.
Modifications have been made to the pretreatment process at Ingersoll-Rand and
toxicity results indicate acceptable levels (the test gives only pass/fail results) for the
past two years.
The North Carolina Wildlife Resources Commission response also noted that they
"generally recommend conversion from chlorine and de -chlorination to ozonation or
ultra -violet disinfection processes for WWTPs". While this technology is appropriate
MI for the construction of new plants, or major expansions, the proposed expansion of
Dutchmans Creek WWTP is a minor one (only 300,000 gpd). The operations staff is
comfortable with the use of chlorine and de -chlorination, and ozonation and/or ultra-
violet disinfection is not currently in use anywhere in the Town of Mocksville's system.
Based upon these mitigating circumstances, and the fact that the NCWRC only lists
this as a general recommendation, the use of this technology is not deemed
f economically feasible for this particular application.
Potential impacts to water quality during construction of the project consist of
FM sedimentation from on -site soil erosion.
3.6.2.2. Indirect Impacts
Indirect impact of the project on water quality consists of increased effluent from the
Dutchmans Creek WWTP discharged to Dutchmans Creek. This will occur as normal
�, growth occurs in the Town of Mocksville's sewer system service area. Also the project
will allow for increased development in the Town's sewer service area. This
development may result in increased area of impervious surfaces that may affect
water quality through non -point source pollution.
3.6.2.3. Cumulative Impacts
The cumulative impacts of the project will be a reduced level of risk associated with
the categorical effluent being discharged from Ingersoll-Rand. There will also be an
rM impact to Dutchmans Creek of increased effluent as a result of normal growth
occurring in and around the Town of Mocksville.
M 3.6.3. Mitigation
Construction activities associated with the project will be performed using appropriate
r' sedimentation and erosion control measures to avoid or minimize the impact of sediment
being transported into Dutchmans Creek. A sedimentation and erosion control plan will
be developed and submitted to the North Carolina Department of Environment and
""' Natural Resources' Division of Land Resources for review and permitting. All other
construction activities will utilize best management practices.

3.7. Coastal Issues
There are no coastal issues as the project is located in Davie County, which is not a coastal
county.
3.8. Socio-Economic Issues/Environmental Justice
'92' 3.8.1. Affected Environment
Based on 2000 U.S. Census data, the Town of Mocksville has a population of 4178. The
Mn total minority population is 997, or 24%. The percentage of persons living below the
poverty level is 12%. Portions of the 2000 U.S. Census are included in Appendix III.
Mn The proposed project will result in system wide improvements, and does not include
construction elements (i.e., sewer line extensions) that will serve site -specific areas in
Mocksville. The Dutchmans Creek WWTP is located outside the Town of Mocksville in a
relatively unpopulated area.
O, 3.8.2. Environmental Consequences
3.8.2.1. Direct Impacts
The project will result in system wide improvements, and does not include sewer line
extensions. There will be new jobs created by two major industries already located in
OZ, the area that will provide employment opportunities to the residents. These are
existing industries who have committed to expanding their work force if the Town of
Mocksville can provide the increase wastewater treatment capacity to support the
r� additional operations.
3.8.2.2. Indirect Impacts
n
The project will provide for adequate wastewater treatment capacity to serve future
growth in Mocksville. The Town of Mocksville will not base decisions on new
connections to the system on race or income levels.
The project's resultant increase in wastewater treatment capacity has been tied to the
pq addition of jobs at two large industrial firms in the area. Also, the additional treatment
capacity has the potential to encourage additional economic development in the sewer
system area. This will have a positive impact on the area in the form of increased tax
r, base and new jobs.
r--;l

`W 3.8.2.3. Cumulative Impacts
The cumulative impact of the project on the social and economic condition in the Town
of Mocksville will be the additional jobs committed to by the two local industries plus
the anticipated economic development in the Town's sewer service area.
rml 3.8.3. Mitigation
MI There are no mitigation measures necessary for impacts to socio-economic conditions
associated with the project.

3.9. Miscellaneous
3.9.1. Air Quality
3.9.1.1. Affected Environment
The proposed Town of Mocksville Dutchmans Creek WWTP upgrade project consists
of two project elements occurring at separate locations. The WWTP upgrade will be
conducted at the site of the current WWTP. The site covers approximately eight
r, acres, with approximately two acres already developed. The expansion is expected to
result in approximately one acre being developed. The proposed pump station will
occur on the property owned by Ingersoll-Rand. The associated force main will be
installed in the Town of Mocksville's street rights of way.
3.9.1.1.1. Environmental Consequences
3.9.1.1.1.1. Direct Impacts
The direct impact of the project on air quality will be temporary increases in dust
and exhaust emissions from construction equipment. Also, approximately one
acre will be disturbed at the WWTP site for development.
r -,
3.9.1.1.1.2. Indirect Impacts
M
The project's resultant increase in wastewater treatment capacity has the
potential to encourage development in the sewer system service area. This
development may lead to an increase in vehicle emissions and emissions from
industries.

912104 Town of Mocksville's Dutchman Creek WWTP Upgrade Page 15 of 21

ap
Ock 3.9.1.1.1.3. Cumulative Impacts
The cumulative impacts of the project on air quality area temporary increase in
`M dust and exhaust emissions from construction equipment and a possible
increase in automobile and industrial emissions associated with future growth.
3.9.1.2. Mitigation
flwl Due to the minimal impact during construction, and the small size of the construction
sites, no air quality mitigation measures are feasible.
3.9.2. Transportation
3.9.2.1. Affected Environment
The proposed Town of Mocksville Dutchmans Creek WWTP upgrade project consists
of two project elements occurring at separate locations. The WWTP upgrade will be
conducted at the site of the current WWTP. The site covers approximately eight
acres, with approximately two acres already developed. The expansion is expected to
result in approximately one acre being developed. The proposed pump station will
occur on the property owned by Ingersoll-Rand. The associated force main will be
installed in the Town of Mocksville's street rights of way.
3.9.2.1.1. Environmental Consequences
3.9.2.1.1.1. Direct Impacts
The construction activities associated with the WWTP upgrade element of the
project will not have a significant impact on traffic as the current site is outside
M the Town of Mocksville, and is located on a remote site off a dead end road.
The Installation of the pump station will also not have a significant impact on
traffic as the location is on an industrial site. The associated force main will be
installed in the Town of Mocksville street rights of way. The force main
installation will result in minor traffic delays. Street crossings will be bored and
jacked to reduce the impact on traffic. No streets will be closed during the
construction phase of the project.
3.9.2.1.1.2. Indirect Impacts
The project's resultant increase in wastewater capacity, plus the additional jobs
committed to by local industry, have the potential to encourage additional
economic development in the sewer system service area. This development
may lead to an increase in traffic in the area. Also the addition of the proposed
Mq
9/2/44 Town of Mocksville's Dutchman Creek WWTP Upgrade Page 16 of 21

Wal-Mart development would increase traffic. This is being addressed with
NCDOT.
3.9.2.1.1.3. Cumulative Impacts
The cumulative impacts of the project to transportation are some temporary
traffic delays associated with the installation of the force main and possible
increases in traffic associated with future economic development.
3.9.2.2. Mitigation
Since transportation impacts associated with the project are expected to be minor and
temporary, no mitigation efforts are planned.
r' 3.9.3. Noise
3.9.3.1. Affected Environment
The proposed Town of Mocksville Dutchmans Creek WWTP upgrade project consists
of two project elements occurring at separate locations. The WWTP upgrade will be
conducted at the site of the current WWTP. The site covers approximately eight
acres, with approximately two acres already developed. The expansion is expected to
result in approximately one acre being developed. The proposed pump station will
occur on the one hundred thirty two -acre tract owned by Ingersoll-Rand. The
associated force main will be installed in the Town of Mocksville's street rights of way.
3.9.3.1.1. Environmental Consequences
r., 3.9.3.1.1.1. Direct Impacts
Mn
During the construction of the project, there will be a temporary increase in
noise in the construction areas. The impact will be greater during the force
main installation portion of the project as that work will be performed within the
Town of Mocksville.
Noise impacts during construction activities at the WWTP site will be minimal
due to its remote location in a sparsely populated area outside the Town. Noise
impacts during construction activities at the pump station location will also be
minimal due to its proximity to the industrial plant and the buffering effect of the
buildings.
912104 Town of Mocksville's Dutchmans Creek WWTP Upgrade Page 17 of 21

Noise impact after construction will be from increased blower capacity at the
WWTP. The impact of the blowers is not deemed to be significant due to the
remote location of the WWTP in a largely unpopulated area.
3.9.3.1.1.2. Indirect Impacts
There will be no significant increase in noise attributed to this project.
3.9.3.1.1.3. Cumulative Impacts
Rn The cumulative noise impacts of this project will be a temporary increase in
noise levels during construction
3.9.3.2. Mitigation
Construction activities will be limited to daylight hours, Monday through Friday to
r' minimize the impact to the surrounding areas.

SUBJECT: State Clearinghouse Project No. 03-0202, Town of Mocksville and
Ingersoll-Rand Pump Station and Force Main. Department of Commence
- Community Development Block Grant Request, Davie County
This correspondence responds to a request by you for our review and comments
— on the Environmental Assessment (EA) for the referenced grant for sewer collcetion
transfer station improvements. These comments are provided in accordance with the
provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16
., U.S.C. 661-667d.) and the North Carolina Environmental Policy Act (G.S. 113A-1
through 113A-10; 1 NCAC 25).
— The Town of Mocksville proposes to install a pump station and sewer line to
transfer wastewater to the Dutchmans Creek wastewater treatment plant (WWTP). This
wastewater is currently produced by Ingersoll-Rand and pretreated before being
discharged to the Bear Creek WWTP. Ingersoll-Rand is contributing 60,000 gallons per
- day of pretreated wastewater pius 36,000 gallons per day of remediation waters to the
Bear Creek WWTP. This industrial discharge may contribute to toxicity problems. Bear
Creek WWTP is under a toxicity moratorium. Ingersoll-Rand desires to expand
operations, add 60 new jobs and increase pretreatment wastewater volume by 70,000
gallons per day. The Town is requesting $720,000.00 in public grants in order to transfer
Ingersoll-Rand's wastewater from the Bear Creek WWTP (0.25 MGD) to the Dutchmans
Creek WWTP (0.681 MGD). The submittal indicates that the transfer would "serve to
lift the moratorium off' the Bear Creek WWTP.
The North Carolina Wildlife Resources Commission has not been informed as to
whether or not the proposed transfer would improve or degrade aquatic habitat conditions
in Bear Creek or Dutchmans Creek. The Dutchman's Creek WWTP may provide
additional dilution of the Ingersoll-Rand pretreated wastewater effluent. It is our

understanding that Dutchman Creek has fecal coliform problems and also significant
dissolved oxygen (DO) problems that may be associated with the WWTP discharge.
We are concerned that the transfer (with or without requested additional flows)
may simply shift a toxicity or pollution problem from one aquatic ecosystem to another.
Therefore, we recommend that the Town of Mocksville and Ingersoll-Rand provide
toxicity testing for various concentrations of pretreated effluent with Dutchmans Creek
WWTP wastewater to determine what impacts may occur prior to public fund issuance.
These tests should incorporate anticipated industrial flow increases. Information gained
from toxicity testing should be used to reduce effluent and toxicity problems and improve
wastewater discharge characteristics. Testing activities should follow toxicity modeling
and sampling protocols established by the NC Division of Water Quality.
As public funds are being requested to subsidize a private industrial expansion,
pretreatment improvements should be provided at Ingersoll-Rand to further alleviate
toxicity and effluent problems. The NCWRC generally recommends conversion from
chlorine and de -chlorination to ozonation or ultra -violet disinfection processes for
WWTPs, especially in slow moving creeks and small streams.
Providing that Division of Water Quality toxicity sampling and testing protocols
determine that the transfer will not simply move toxicity or wastewater problems from
Bear Creek to Dutchman Creek, we will not object to the use of Community
Development Block Grant public funds. However, if toxicity or other pollutants will
contribute to or exasperate water quality in Dutchmans Creek, we request the opportunity
to reconsider the project based on any new information. As appropriatc, we will review
construction plans for the pump station and appurtenances during the 404 Permitting or
�► -'.01 Certification process.
Thank you for the opportunity to review and comment on this project. If you
ram, have any questions regarding these comments, please contact me at-3 36/769-9453.

The Bog Turtle (Glyptemys muhlenbergir), a federally threatened species, occurs in boggy,
swampy wetlands, but is considered a potential resident of the area. It has not been seen in
Davie County, but suitable habitat is considered to be available. The southern population of Bog
Turtle in our region is considered threatened only because of its similarity of appearance (S/A) to
r, the northern segment of the population of the species, which does not occur here.
Michaux's Sumac (Rhus michauxir), a federally endangered low shrub of mesic to xeric sandy or
Po, rocky open woodlands occasionally subject to disturbances such as irregular mowing (not
usually road shoulders, but possibly on shrubby road embankments), fire or forestry practices,
currently is known to occur in the Mocksville 7.5' US Geological Survey quadrangle of Davie

w"

County. There is a sufficient amount of variation in habitat preference that this species might
can occur in shrubby or wooded sites. It is the only federally listed species, which warrants attention.
Within Davie County as a whole, there are additional natural elements with significance at the
federal level. Species with an FSC federal status do not technically fall within the domain of the
Endangered Species Act. They are still being evaluated for inclusion under the Endangered
Species Act. The Redhorse (Moxostoma robustum), a creek fish, is under review by the US Fish
M-1 and Wildlife Service, but not yet listed federally because of lack of information. Other species
that may be found in Davie County which fall into this category are Yellow Lampmussel
(Lampsilis cariosa), a mollusk; Cherokee Clubtail (Gomphus consanguis), a dragonfly; Creamy
Tick -trefoil (Desmodium ochroleucum), a flowering plant; and Carolina Birdfoot-trefoil (Lotus
hellen), a flowering plant.
