Wastewater Treatment Lagoon—Lagoon Closure Report
Headwater Geology 1
1 Introduction
Headwater Geology PLLC. (Headwater), on behalf of Fletcher Academy, Inc. (Fletcher Academy),
prepared this Lagoon Closure Report documenting closure activities for a wastewater treatment
lagoon located on PJs Place Road, in Fletcher, North Carolina (the Site). The lagoon location is
shown on the attached Figure 1, Figure 2, and Figure 3. The Fletcher Academy connected to a
municipal sewer system on March 5, 2021, and therefore has closed the existing lagoon and
wastewater treatment system.
Headwater submitted the Lagoon Assessment Plan—Revision 3 on February 12, 2020
(Headwater 2020a) to the North Carolina Department of Environmental Quality (DEQ) Division of
Water Resources (DWR). The sludge/residuals assessment portion of the plan was approved by
DEQ on November 13, 2019, and the full Assessment Plan was approved by email on February
13, 2020.
Following assessment activities, Headwater submitted a Lagoon Assessment Report to DEQ on
June 11, 2020 (Headwater 2020b). Following review and correspondence with DEQ, the DEQ
requested that a dewatering plan be prepared to describe the plan to drain and ultimately close
the lagoon. A dewatering plan was submitted to DEQ and to the Buncombe County Metropolitan
Sewerage District (MSD) on September 22, 2020. The dewatering plan was approved in an email
from DEQ sent on October 2, 2020. Subsequently, the Lagoon Assessment Report and Closure
Plan (Headwater 2020c), dated October 6, 2020, was revised to include both the assessment
results, the dewatering plan, and additional detail regarding sludge removal.
Lagoon closure activities were performed in general accordance with the Lagoon Assessment
Report and Closure Plan. Any variations to the plan were performed in coordination with DEQ
and MSD. Lagoon dewatering, sludge removal, and lagoon closure activities are documented
herein.
1.1 Lagoon Background Information
Wastewater generated by the Fletcher Academy, Captain Gilmer Christian School, Fletcher Park
Inn Retirement Community, AdventHealth Hendersonville Hospital, and multiple private
residences was treated by the Site lagoon and associated infrastructure. The Site wastewater
treatment system (WWTS) is associated with National Pollutant Discharge Elimination System
(NPDES) permit number NC0036641. Treated wastewater was discharged to Byers Creek. A new
municipal sewer line, associated with the Cane Creek Sewer District, was constructed to connect
this waste stream to the Buncombe County MSD municipal sewer system. The new sewer line
was connected on March 5, 2021.
Headwater understands that the original permit was issued in October 1988. According to the
permit, the Site lagoon is composed of a 2.094 million-gallon, clay-lined, earthen lagoon
subdivided into four cells, separated by floating curtains. Floating aerators were also present in
the lagoon. Influent would enter the lagoon on the eastern end where it was aerated and would

progress westward through the lagoon. Prior to discharge, wastewater was chlorinated and
subsequently de-chlorinated by infrastructure located at the southwestern corner of the lagoon.
The lagoon is approximately 400 feet long by 100 feet wide.
Headwater was provided a sludge monitoring data prepared by the Fletcher Academy that
indicated sludge thickness was measured at approximately 0 to 60 inches between 2007 and
2014. This report indicated that the lagoon water depth ranges from approximately 7 to 10 feet. A
probiotic solution had been applied during this time period to reduce sludge thickness.
Three monitoring wells located adjacent to the lagoon were installed in 1986 and sampled
annually or bi-annually until the requirement to monitor groundwater was removed from the permit
in September 1998. According to a memo sent on September 16, 1998 from Kay Dechant to Bob
Cheek, through Don Link (representatives of the North Carolina Department of Environment and
Natural Resources, Division of Water Quality), the facility has shown no exceedances of
groundwater standards except for sporadic coliform. Surface water and groundwater sampling
performed during Headwater’s assessment also did not indicate the presence of contaminants in
surface or groundwater (Headwater 2020c).
1.2 Lagoon Assessment and Closure Plan Summary
Lagoon assessment activities were performed in general accordance with the July 2007 North
Carolina Department of Environment and Natural Resources (DENR) Guidelines for the Closure
of Treatment Ponds and Lagoons (DENR 2012) as well as the Lagoon Assessment Plan—
Revision 3 (Headwater 2020a). Results of this assessment are documented in the Lagoon
Assessment Report and Closure Plan (Headwater 2020c), dated October 6, 2020.
Assessment activities included:
Assessment for the presence and thickness of sludge in the lagoon
Collection of sludge samples for laboratory analysis
Collection of surface water and groundwater samples for laboratory analysis
Based on the sludge thickness evaluations, approximately 2,500 cubic yards of sludge were
estimated to be present in the lagoon. The majority of sludge was observed in Cell #3 and
measured up to 6 feet thick, with lesser amounts in Cell #4 and Cell #2. Only trace amounts of
sludge were observed in Cell #1. Approximate sludge thickness is shown on Figure 2.
Analytical results indicated that the sludge does not have the potential to leach constituents at
Resource Conservation and Recovery Act (RCRA) hazardous concentrations. The sludge is rich
in nitrogen compounds and phosphorous and contains elevated concentrations of fecal coliform
bacteria.
There were no constituents detected above applicable standards in surface water or groundwater.
The results of the surface and groundwater sampling indicate that the lagoon liner was functioning

properly, and surface and groundwater have not been impacted by the lagoon. Surface and
groundwater sample locations are shown on Figure 3.

2 Lagoon Closure
Lagoon closure included the following primary steps:
Lagoon dewatering
Sludge Removal
Lagoon berm, structures, and clay liner demolition and Site stabilization
Lagoon dewatering began after the lagoon was disconnected from additional effluent on March
5, 2021 (when the new sewer line connection occurred). Dewatering was substantially completed
by mid-April 2021 when additional water floating on sludge could not feasibly be removed without
entraining sludge in the discharge.
Sludge management, solidification, and transport was performed by Advanced Environmental
Options (AEO), located in Spartanburg, South Carolina and was performed from mid-March until
June 3, 2021, when sludge removal was completed.
Spading of the clay liner of the bottom of the lagoon began in mid-May 2021. The lagoon berm
was collapsed and grading of the lagoon area, to provide positive drainage, was completed by
AEO the week of June 14, 2021.
A detailed summary of these steps is included in the following subsections. A photographic log is
included as Appendix A.
2.1 Lagoon Dewatering
The lagoon was disconnected from additional influent on March 5, 2021, when the facility was
connected to the municipal sewer. Discharge of effluent continued through the NPDES permitted
discharge during March 5, 6, and 7, 2021 until the water level in the lagoon was at the same level
as the highest effluent collection line in the lagoon. This line was located at a depth of about 2
feet below the former lagoon surface.
Discharge of lagoon wastewater to the sewer system began on the afternoon of March 8, 2021.
This discharge was performed using a pump connected to an intake floating in the middle of Cell
#1 of the lagoon. Initially, a filter fabric box was placed around the intake of the pump. However,
based on turbidity measurements of the effluent and in the lagoon itself, the filter fabric box was
removed, as it was contributing to a reduced flow rate and the filter fabric was difficult to replace
with clean fabric. Water was pumped from the lagoon to former sewer piping infrastructure that
previously discharged to the lagoon. Using this infrastructure, wastewater could be metered
through the existing weir meter. After the meter, additional pipe infrastructure diverted the
discharge into a sewer manhole associated with the newly constructed sewer line. Turbidity of
the discharge was measured approximately every 30 minutes using a Hach turbidity meter to
ensure water clarity was 75 Nephelometric Turbidity Units (NTUs) or less. Note that in
coordination with Mr. Roger Edwards (MSD), the turbidity limit was later raised as described
Wastewater Treatment Lagoon—Lagoon Closure Report
Headwater Geology 5
herein. Biological oxygen demand (BOD) was measured approximately bi-weekly and total
suspended solids (TSS) was measured approximately weekly by James and James
Environmental Mgt. Inc. during discharge events.
A second pump was soon added to the dewatering system so that initial pumping rates ranged
from about 85 to 170 gallons per minute (GPM). However, pumping was stopped on March 12,
2021, due to increasing turbidity levels. As sludge was exposed in the middle of the lagoon, it
began migrating outward. Also, small streams of water were observed flowing from water that had
pooled in Cell #4, across sludge mounded in the middle of the lagoon, and toward the pump intake
in Cell #1. This resulted in increased turbidity levels. The water and sludge level in the lagoon
was measured at about 4.5 feet deep at this point.
By March 17, 2021, pumping was performed using small sump pumps at a rate of about 5 GPM.
Prior to discharge, the effluent was pumped through drum filter systems consisting of an
approximately 50-gallon plastic drum with the top cut off, filled from the bottom with a layer of
stone, filter fabric, washed sand, and an additional layer of filter fabric. The top layer of filter fabric
would need to be replaced every 4 to 6 hours of pumping. The drum filters reduced the turbidity
of the water in the lagoon from approximately 250 to 170 NTUs. However, TSS samples collected
of this effluent and the corresponding lagoon source water indicated that TSS was reduced from
276 milligrams per Liter (mg/L) to 14 mg/L as indicated by samples collected on March 17 and
18, 2021. Mr. Adam Tripp with Headwater discussed these results with Mr. Roger Edwards with
MSD on March 19, 2021. Mr. Edwards suggested that turbidity measurements for water pumped
through the sand filter could be used as a subjective guide since they were not well correlated
with TSS, and ultimately TSS was a better measurement of solids/sludge being entrained in the
effluent. Mr. Jason McDonald with FAI and Mr. Tripp had previous conversations with Mr. Edwards
regarding challenges removing water and meeting the initial turbidity limits of 75 NTUs. Mr.
Edwards had suggested increasing the turbidity limits incrementally, eventually up to 175 NTUs
for water that did not pass through the sand filter. Additionally, certain exceptions to the 175 NTU
limit were made for specific dewatering periods based on discussions between Mr. McDonald and
Mr. Edwards.
On March 17, 2021, an earthen dam was constructed in the middle of Cell #1. The contents of
the eastern side of the earthen dam were pumped into two sludge dewatering bags. The rate of
filtration through the dewatering bags decreased rapidly. The eastern portion of Cell #1 was then
converted into a sludge solidification pit. The filter bags used were an Interstate Products Ultra-
Dewatering Bag 9725-O/S Oil & Sediment Model, 10' x 15' with pore rating of 80 Microns.
By March 23, 2021, the majority of accessible water had been removed from the remainder of the
lagoon. After rain events, water was pumped directly from the surface of the lagoon at a rate of
about 85 GPM. When pumping in this manner was no longer feasible, water was pumped though
sand filters using small sump pumps at about 5 GPM. Although there were still areas of ponded
water above sludge, it was difficult to pump this water as the sludge layer was very close to the
Wastewater Treatment Lagoon—Lagoon Closure Report
Headwater Geology 6
surface of the water and pumping could not easily be performed without entraining sludge in the
effluent. The sludge/water depth at this point was approximately 4 feet deep. Subsequent
pumping of wastewater was performed only after rain events.
On April 4-5, 2021, water that had accumulated on top of sludge in Cell #4 that could not flow to
the other end of the lagoon was pumped to the eastern end of the lagoon, adjacent to Cell #1.
After a period of settling, this water was then pumped into an additional filter bag. The filter bag
performed better by keeping the inlet hose at the surface of the water, connected to the back of
a boat partially anchored to the bank to modulate the depth of the hose intake. Using the filter bag
in this manner was much more successful for filtering water. A sample of the filtered water was
collected on April 5, 2021 and TSS was measured at 642 mg/L. Mr. McDonald discussed these
results with Mr. Edwards and estimated that less than 10,000 gallons of wastewater may be
removable in this manner. Based on the relatively low volume, Mr. Edwards suggested that water
pumped through the filter bag was acceptable for discharge to the sewer.
A summary of TSS, turbidity, and BOD measurements is as follows, as shown in the attached lab
reports provided by James and James Environmental (Appendix B).

2.2 Sludge Solidification and Disposal
Sludge solidification, transport, and disposal was performed by AEO between mid-March to June
3, 2021. During the dewatering process, on March 17, 2021, an earthen dam was constructed in
the middle of Cell #1. After the water on the eastern side of the berm was substantially removed,
this area was used as a solidification pit. It was later modified into two solidification pits to allow
for solidification and loading to occur simultaneously in separate pits. The first pit was located
directly adjacent to the berm so that sludge could be moved from the lagoon by excavator bucket
directly into this pit. A second pit was located adjacent to the access road to the north of the first
solidification pit so that the second pit could be used for loading. Solidification was performed by
adding a super absorbent polymer (SAP) that was a byproduct of the manufacture of diapers.
Generally, sludge would be placed in the first solidification pit and would be mixed with SAP and
allowed to solidify overnight. The solidified sludge would then be moved to the second pit used
for loading and would be loaded into dump trucks for transport to the landfill. Additional SAP would
be added as needed. The process would then be repeated. Note that a solidification pit was also
constructed and used at the western end of the lagoon early in the project to remove sludge from
Cell #4. However, this solidification pit was later emptied and abandoned in favor of the pits
constructed at the eastern end of the lagoon in Cell #1. As sludge was removed from the lagoon
and the sludge level was reduced, the sludge was pushed inward and eastward, toward the
solidification pits in Cell #1. This was accomplished by using the excavator bucket to push a
portion of the lagoon wall downward so that it would displace sludge and effectively move the
lagoon wall inward and eastward.
Solidified lagoon sludge was transported to Santek Environmental of North Carolina’s White Oak
Landfill, located in Waynesville, Haywood County, North Carolina under an approved waste
profile. A total of 3,393.62 tons of solidified sludge was disposed of at the White Oak Landfill.
Once the lagoon or a particular cell was free of residual sludge, Headwater contacted Mr. Brett
Laverty of the DEQ to visually inspect the lagoon or cell(s) and to confirm that the lagoon or cell
was “closed” and no longer subject to wastewater treatment requirements. Mr. Laverty visited the
Site on May 21, 2021 and June 4, 2021 to perform inspection of sludge removal progress and
completion. Specifically, Mr. Laverty observed that sludge had been removed from approximately
midway through former Cell #2 to the end of Cell #4 on May 21 and observed that all sludge had
been removed from the entire lagoon on June 4, 2021. Note that confirmation soil samples of the
base of the lagoon were determined to be unnecessary because the sludge was determined not
to contain hazardous materials and therefore neither would the liner (Headwater 2020c).
Waste manifests are included in Appendix C.
2.3 Lagoon Structure and Liner Demolition
After sludge had been removed from the lagoon, the clay liner was compromised. The liner was
“spade” which consists of scooping a bucket of clay liner and laying it to the side with the excavator
Wastewater Treatment Lagoon—Lagoon Closure Report

bucket. This method meets the goal of preventing the clay liner from holding water and helped to
dry the clay by better mixing it with surrounding residual soils.
After compromising the liner, the lagoon structure was then properly decommissioned by
breaching the southern berm of the lagoon and collapsing it inward so that the soil composing the
berm was used to fill the lagoon. The fill soil was placed and graded so that the Site gently slopes
to the south. Soil was compacted by tracking heavy equipment across the soil. At the completion
of grading activities, the Site was stabilized with grass and straw matting.
2.3.1 Additional Structure Demolition
Influent piping was removed and disconnected from the waste stream at the location where the
new sewer line intersected the existing sewer infrastructure. Effluent piping was removed from
the lagoon and remaining piping was abandoned in place at a location approximately 30 to 40
feet south of the former southern berm of the lagoon. The curtains used to divide the cells in the
lagoon were removed and disposed of as construction and demolition debris. Additional concrete
infrastructure associated with water treatment processes at the southwestern edge of the lagoon
was demolished, crushed, and used as fill material within the collapsed lagoon structure. The
chlorine building and main building were also demolished and disposed of as construction and
demolition debris. Power poles were also removed and repurposed.

3 Conclusions and Recommendations
The lagoon was drained and a total of 1,017,100 gallons of water was discharged to the new
sewer system. Lagoon residuals were solidified and properly disposed of at the White Oak Landfill
located in Haywood County. A total of 3,393.62 tons of residuals/sludge were disposed.
The clay liner at the base of the lagoon was compromised so that it would no longer hold water
and the lagoon’s southern berm was collapsed inward and graded so that the Site would drain
properly. The Site was then stabilized with seed and straw matting.
Lagoon infrastructure, including influent and effluent piping, power poles, buildings, and concrete
structures were demolished.
Wastewater that formerly was treated in the lagoon now discharges to a new sewer line
associated with the Cane Creek Sewer District and connected to the Buncombe County MSD
municipal sewer system.
Based on these results, Headwater recommends that the Site’s NPDES permit (# NC0036641),
be rescinded and a letter of “No Further Action” be issued for the project. Restrictions associated
with potential future Site usage are not recommended.
