AREA I
The Area I ash fill, completed in the fall of 2010, is an approximately 18-acre fill area on the north end of
the Airport located east of the runway. The fill area is designed to slope north at a 2.5%grade across
the top of the fill area. The outer slope of the fill was built to a 33% (3HAV)slope. A wetland area,
stormwater structures, and outfalls are located at the north toe of the Area I slope.
There is a 100-foot wide compacted soil core over the length of a 60-inch diameter stormwater pipe that
transects the ash fill. The pipe flows south to north and is part of drainage from the Airport runway
areas. The compacted soil core is to ensure that ash is not located within 50 feet of a stormwater pipe.
Area I is lined with geosynthetic clay liner(GCL)on the bottom. The cap system for the area is a
vegetated compacted soil cover. The top of the fill system with the 2.5%grade is constructed with a 6-
foot thick soil cap. The outer slopes are constructed with a 2-foot thick soil cap as designed. The detail
for the cap is shown in the figure below. The detail shown below is from the drawing set"Asheville
Regional Airport-Fly Ash Beneficial Use Project," issued by Charah, revised December 2007.

Area I Observations
The October 2015 inspection identified exposed ash at the cap in the northwest corner,areas with over
grown vegetation,and several areas of minor erosion on the slopes. The exposed ash in Area I was
excavated and removed from the site and compacted soil was placed to restore cover. Additional
temporary erosion control measures were put in place in the area, including silt fencing, reseeding, and
a series of berms and pumps to divert water until a permanent grading plan could be developed and
executed. Further inspections of the area in November and December revealed these temporary
measures were successful in diverting water and avoiding further erosion.
The photos below illustrate the measures taken to confirm cap thickness, reduce erosion, and establish
vegetation in Area I. The areas were stripped of vegetation as shown in Photo 1. Exposed ash was
excavated and placed in on-site roll-off containers. The roll-off containers were transported by
Mountain Environmental for eventual disposal at a lined solid waste facility in Enoree,South Carolina.
Bills of lading are available for review. The excavated areas were brought to grade with soil and
compacted as shown in Photo 2. Photo 2 shows the soil placement and the temporary erosion
measures taken immediately after the conditions were found. Photo 3 shows Area I two weeks after
3

Photo 2 was taken. Flow diversion berms were constructed across the area. The area was reseeded and
straw matting was installed to further reduce erosion.

As a result of this clearing,an apparent weep and scarp were noted on the north side of the access road
that forms the toe of the fill area. Further geotechnical analysis of this area is warranted to determine
the cause of these items as well as determine if stability factors are acceptable. Duke Energy will work
with the Airport to undertake a geotechnical investigation of this area in the first quarter of 2016.
Photos 6 and 7 below show the condition of the weep and scarp. The weep is a trickle flow. The scarp is
approximately 60 feet in length with depth ranging from eight inches to 18 inches.

Several areas on the north slope of Area I have been repaired by filling in ruts with soil and establishing
vegetation.The east slopes of the fill area have adequate vegetation, no visible erosion,and are in good
condition. Minor erosion was noted in areas along the south slope as well as some small animal
burrows that need to be addressed. The top of the fill has a few minor erosion issues,an area of sparse
vegetation,and a small depression requiring attention.. Duke Energy has identified these areas in the
monthly reports and provided a list of recommended repairs for each issue to the Airport.
Area I Corrective Actions
Duke Energy has been conducting monthly inspections for the final three months of the year in addition
to the prescribed quarterly inspection required under the Permit. Duke Energy will continue with
monthly inspections until the final repair plan is developed and constructed.
Duke Energy is working with Charah and AVCON,the Airport's consulting engineers,to develop a final
repair plan to address the issues noted above and identified in the monthly inspections and NOV.
The following schedule is proposed for completion of the permanent design, permitting, and
construction.
• 60 days to complete permanent designs for Area I and review existing permanent
stormwater management plan for Area IV(March 1, 2016)
• 45 days to complete necessary permitting with NCDEQ(April 15,2016)
• 60 days to complete construction activities on-site(June 15, 2016)
Upon completion of the permanent repairs, Duke Energy will return to quarterly inspections of Area I.

AREA III
The Area III ash fill, currently completing construction,is an approximately 29-acre ash fill located west
of the runway on the northern portion of the airport property. Area III is constructed (from bottom to
top)with a compacted soil subgrade,geosynthetic clay liner, and 60-mil geomembrane liner with
leachate collection pipes on top of the liner. The leachate collection system gravity drains to the
Metropolitan Sewerage District of Buncombe County(District). Leachate flow has consistently been
observed at 6-7 gallons per minute. The cap for Area III is a flexible membrane with soil cover on top of
it. The geomembrane in the cap system is 40-mil textured HDPE. The cap thickness is six feet on top
and two feet on the side slopes as designed. The design details shown below are from the drawing set,
"Asheville Regional Airport, Engineered Fill-Area 3," issued for construction by Charah on March 15,
2013.

As of the December 2015 inspection,Area III has an open Erosion and Sediment Control (E&SC) permit
held by the Airport. Final phases of construction are still ongoing in the area. The photos presented
below show that vegetation is just being established on the top of the north end of the fill and along
much of the north and west slopes. The Airport has constructed a runway on the top portion of the fill.
Other than a few minor erosion areas associated with establishing vegetation,the slopes of this area are
in good condition.

Area III Corrective Actions
Area III does not have any issues identified for corrective action. Duke Energy will continue to include
the area in its inspections.
Area III is currently being completed and will be turned over to the responsibility of the Airport for
future maintenance.

AREA IV
The Area IV ash fill,substantially completed April 1, 2015, is located to the west of the Airport
runway. The 28-acre fill area was constructed in three different phases: Phase I, Phase IA,and Phase
2. Area IV is constructed (from bottom to top)with a compacted soil subgrade,geosynthetic clay liner,
and 60-mil geomembrane liner with leachate collection pipes on top of the liner. The'leachate collection
system gravity drains to the District. Leachate flow has consistently been observed at 4-5 gallons per
minute.
The cap system is similar to Area III noted above, but it was designed with a 30-mil geomembrane cap.
The soil thickness on the cap is six feet on top and two feet on the side slopes as designed.

Area IV Observations
The October 2015 inspection identified exposed geomembrane liner along the western slope (but not
exposed ash),areas with over grown vegetation, and several areas of erosion on the slopes. The area
with the exposed cap was filled with soil and a sandbag diversion ring was installed to divert surface
water until a permanent grading plan is developed and implemented. Further inspections of the area in
November and December 2015 revealed the temporary measures were successful in diverting water
and avoiding further erosion.

Area IV is currently being utilized as a construction laydown area adjacent to the new runway. The
Airport holds an E&SC permit for Area IV in relation to the construction activities for the new runway.
Several minor erosion areas along the western slope were identified. There are several slope drains
with erosion around the rip rap at the drain discharge and several erosion channels north of the
retaining wall. The entire slope is covered with vegetation over twenty-four inches tall that limits
inspection. Duke Energy has identified these areas in the monthly reports and provided a list of
recommended repairs for each issue to the Airport.
Area IV Corrective Actions
Duke Energy conducted monthly inspections for the final three months of the year in addition to the
prescribed quarterly inspection required under the Permit. Duke Energy will continue with monthly
inspections until the final repair plan is developed and constructed.
Duke Energy is working with Charah and AVCON,the Airport's consulting engineers,to develop a final
repair plan to address the exposed geomembrane noted above and the issues identified in the NOV.
The following schedule is proposed for completion of the permanent design, permitting, and
construction.
• 60 days to complete permanent designs for Area I and review existing permanent
stormwater management plan for Area IV(March 1,2016)

Part 2 - Annual Report Additional Information Required by NOV
Pursuant to the NOV, NCDEQ required a response to certain items in this Report. Each of NCDEQ's
requests for information are set forth in italics with Duke Energy's response following.
1. Duke subcontractors indicate that a soil cap thickness of 4 ft. was present on the slopes of
Area IV upon completion of the cell. The Division is requiring verification of soil cap
thicknesses along the entire slope face of Area IV. Any discrepancies between the soil cap
thickness as designed and constructed and the existing soil cap thickness shall be explained.
There are no discrepancies in the design of the soil cap for the Area IV structural fill project. The design
for Area IV provides for a soil cap thickness across the surface of six(6)feet and a minimum of two (2)
feet on the side slopes. As built surveying was performed by WNC Engineering and Surveying and
confirmed all infrastructure locations,separation, and soil cap thicknesses. Copies of GeoTrack
Technologies'Construction Quality Assurance certifications are available upon request. NCDEQ was
notified of this cap configuration in a letter dated December 1, 2011 (see Attachment"1").
2. Conceptual design plans for Area I indicate a soil cap thickness of 4 ft. on slopes and 6 ft.or the
crown of the structural fill. The Division is requiring verification of soil cap thicknesses along the
entire slope face of Area I as well as all recent repair area. Any discrepancies between the
soil cap thickness as designed and constructed and the existing soil cap thickness shall be
explained. Refer to 3.d. below.
There are no discrepancies in the design of the soil cap for the Area I structural fill project. Area I was
designed with a soil cap system of six(6)feet of soil across the surface with two (2)feet of soil along the
side slopes. (See letter from Progress Energy to NCDEQ dated December 23, 2008 discussing the soil cap
thickness at Attachment"2.") Charah conducted hand auger borings and a field run survey during the
week of 12/14/2015 to evaluate in-situ soil cap conditions along the slope of Area I and determined that
minor soil losses have occurred since the project was closed in November 2010. These losses are
concentrated in the northwest corner of the structural fill,which coincides with the areas noted in the
recent inspection completed by NCDEQ and subsequently temporarily stabilized by Charah.
3. Describe all remedial efforts, temporary and long-term;planned to address the Area 1 breach
and Area IV soil cap erosion. This description shall include specifics with regard to:
Temporary remedial actions have been taken to address erosion in Areas I and IV. For Area I, remedial
actions have included constructing temporary stormwater diversion berms, installing silt fencing, re-
grading areas, and establishing vegetation on disturbed surfaces. For Area IV,the area where the cap
geomembrane was exposed has been stabilized with a temporary cover ballasted by sand bags and
riprap. These actions are described in detail with photos in Part 1 of this Report.
The permanent repair plan is under development by Charah and the Airport's consultant,AVCON.
Regarding the specific items noted in the NOV,the responses are described below:
13

a. Removal of the 6"slope drain in Area l;
Removal of the 6"slope drain will be addressed in the Final Repair plan.
b. How the erosive conditions located at two slope drains on Area IV will be stabilized and
repaired;
Rills and erosive conditions will be repaired and monitored until the permanent design configuration for
Area IV is in place. Previously,geomembrane material was placed at the outlet of these slope drains
and covered with rip rap to protect the integrity of the geomembrane cap system below. This system
will be maintained until final removal of the temporary slope drains.
c. The long-term stormwater management design at Area IV, including any required changes to
slope drains and road ditches,
Upon completion of the ongoing temporary runway construction project,slope drains will be removed
and road ditches placed into their permanent configuration. Stormwater and sediment basin volume
calculations were completed with the original design for these improvements and will be adequate
without additional measures or design changes. Information can be submitted with the Area IV
permanent E&SC design package to support this original design.
d. The presence of CCP on the surface of the Area 1 slope in a second area located away from the
stormwater channel;
The CCP noted in this item was investigated and confirmed to be a result of the ongoing repair activities
and equipment performing work on-site as opposed to degradation of the soil cap. Hand auger soil
borings in the area confirmed appropriate cap thicknesses.
e. The treatment and maintenance of observed rills and cavities on the slope face of Areal;
Temporary stabilization measures were completed on November 5,2015. Duke Energy has also
implemented temporary monthly inspections,which are above and beyond the quarterly inspections
required under the Permit. These monthly inspections will continue until the permanent repairs have
been completed.
Erosion rills and gullies were re-graded and stabilized. In areas where the cap had eroded and the
required thickness was not met,soil material was brought in and placed to meet required cap
thicknesses.The final repair plan will address grades in these areas and permanent surface stabilization
procedures to allow for proper drainage in the future. The photos provided in Area I observations of
this Report show examples of the measures taken to date to stabilize the surface.
f. Approximately 12 cubic yards of mixed CCP and soil cap material were removed from the repair
area in Area 1. Please provide information and related documentation of the disposal method;
CCP-impacted materials from the slope and toe areas of Area I were taken for disposal off-site. These
materials (approximately 12 cubic yards)were hauled by a registered environmental disposal company
14

(Mountain Environmental)and properly disposed of in a permitted solid waste facility in Enoree,South
Carolina. Waste manifests can be made available upon request.
g. The maintenance of Area I and Area IV grass cover both on the slope face and structural fill
deck;
The final repair plan will address the vegetation requirements for these areas. In conjunction with the
final repair plan being implemented and the new inspection frequency by Duke Energy, areas will
documented and discrepancies noted.
h. Access paths shall be maintained below Area I to allow inspection of. toe slope area, wetland
areas, all monitoring wells(including those not in the current monitoring schedule),stormwater
outlets, and streams. These access paths will be necessary for adequate inspection in
accordance with permit condition V.2.
Maintenance of the Airport property is the responsibility of the Airport and will continue as such.
Regular inspections as outlined in the Permit and further defined in Duke Energy's Operations and
Maintenance Plan dated October 23, 2015 will ensure such maintenance takes place and any minor
deficiencies are corrected promptly.
4. Aschedule indicating when a long-term storm water solution will be implemented at Area I and
what efforts are currently underway with regard to the design and implementation of a
permanent stormwater management plan for Area IV.
The Area I and Area IV investigations have been completed as noted above and conceptualization of the
permanent repairs is underway. The following schedule is proposed for completion of the permanent
design, permitting, and construction.
• 60 days to complete permanent designs for Area I and review existing permanent
stormwater management plan for Area IV (March 1,2016)
• 45 days to complete necessary permitting with NCDEQ(April 15,2016)
• 60 days to complete construction activities on-site (June 15,2016)

RE: Asheville Structural Fill Project
Asheville Airport—Area IV
Carolina Power&Light Company d/b/a Progress Energy Carolinas,Inc.
Ash Distribution Program Permit No.WQ0000020
Dear Mr.Laverty:
Carolina Power & Light Company d/b/a Progress Energy Carolinas, Inc. (PEC) received your letter
dated October 3,2011 which requested certain information regarding Phase II of Area IV structural
fill at the Asheville Airport. This letter responds to that request(DENR request in italics):
1. According to 15.A NCAC 02T.1204 (d), information shall be provided to the Division of
Water Quality that describes and explains site-specific engineering or institutional controls
proposed to prevent adverse impacts to public health and the environment. Submit a
project narrative for Phase 11 that includes a general overview, timeline,footprint(acreage),
environmental impact statement and completed Phase li engineering construction plans.
Please note the Division (APS) would like the opportunity to review and comment on the
Phase 11 construction design.
The Asheville Airport Area IV structural fill project is divided into three distinct phases, Phase I,
Phase IA and Phase II. The overall fill footprint totals approximately 52.9 acres and will contain
more than 2 million cubic yards of coal combustion byproducts(fly ash and bottom ash). Phase
II itself is approximately 22.7 acres in size and will accommodate approximately 1.1 million tons
of coal combustion byproducts as fill(-777,000 cubic yards).
Phase I/IA is anticipated to be complete by May 2012. Construction of Phase II improvements
will begin in late 2011/early 2012 with coal combustion byproducts placement beginning in late
February 2012. Coal combustion byproducts placement in Phase II will continue to project
completion anticipated in July 2013.
The project design for Phase II is the same as incorporated into Phase I/IA. There will be a 60 mil
HDPE geomembrane used as a liner beneath the coal combustion byproducts fill. Above the
liner is a leachate collection system. The coal combustion byproducts fill will be covered by a 30
mil HDPE geomembrane and then by native soils ranging from 2 feet thick on sideslopes to 6
feet thick in flat areas.

The enclosed compact disc contains the Environmental Assessment(EA)completed by the Asheville
Airport and the Phase II engineering construction plans. Also enclosed are two hard copies of the
Phase II engineering construction plans per your request.
2. Verify that the Phase 11 meets all applicable setbacks established in 15A NCAC 02T.1206.
These include setbacks from water supply wells streams (including those culverted), and
seasonal high water table.
All setbacks have been met. Please see the enclosed Hydrogeologic Assessment Report Asheville
Regional Airport Area IV completed by Silar Services, Inc.along with the engineering construction
plans for setbacks from the seasonal high groundwater table. The Airport has completed the
necessary permitting to take small areas of wetlands& streams within Phase IL There will be no
culvert as within fill Area I and therefore,no impact to the setback requirements for surface waters.
Please refer to Appendix B & H of the enclosed .Environmental Assessment for the permitting
efforts completed by the Airport. The enclosed engineering construction plans show the closest
groundwater well is over 300 feet from the edge of fill for Area IV.

4. If soils within the Asheville City gun range are to be disturbed during Phase 11 then an
environmental assessment should be completed prior to construction. The Division is
concerned that lead contamination could be present within the footprint of the gun range.
Contaminated soils are not recommended for use as a cover material. Please provide a
narrative on the condition of the gun range.

DENRARO
December 1,2011
The City of Asheville owns the firing range and has agreed to vacate the firing range in early 2012.
The City of Asheville has committed to work through NC DENR to remediate the firing range to
'clean closure'. Please refer to Appendix B of the enclosed Environmental Assessment to a letter
dated March 28,2011 from Jeffrey B.Richardson,Assistant City Manager for the City of Asheville.
PEC will work with Charah and the Airport to ensure no 'impacted' soils are used as cover within
Area IV fill project. Per DENR Inactive Hazardous Sites Branch Preliminary Soil Remediation Goals
Table dated August 2011,the lowest established level for lead is for Protection of Groundwater at
270 mg/kg. No soils with lead concentrations at or above 270 mg/kg will be used as cover soils in
Area IV fill project.
PEC proposed an alternative location for a background well for Area IV. The attached figure (E-1)
shows the proposed background well location. PEC proposes to install this background well along
with well PMW-9 upon your concurrence. These two wells along with review boundary wells MW-
2,MW-5(formerly known as PZ-4), MW-6 and MW-7 would complete the monitoring well network
for Area IV. The wells will be sampled in April and November for pH, temperature, water level,
specific conductivity, total dissolved solids, antimony, arsenic, barium, boron, cadmium,
chloride, chromium, copper, iron, lead, manganese, mercury, nickel, nitrate, selenium, sulfate,
thallium and zinc.
If you have any questions,please contact Mt.John Toepfer at 919-546-7863.

RE: Asheville Steam Electric Plant Coal Ash Structural Fill Project
Request for Waiver of 50 Foot Setback
Ash Distribution Program, Permit WQ0000020
Dear Mr.Davidson:
We appreciate the opportunity to meet with you and your staff on December 15, 2008
regarding the subject project. As we discussed at the meeting, Carolina Power&Light Company
d/b/a Progress Energy Carolinas, Inc. is partnering with the Asheville Regional Airport Authority
(Airport)on the North General Expansion Project. The Airport has secured permits from the
Corps of Engineers and the Division of Water Quality to permanently impact 1,535 linear feet of
perennial streams, 138 linear feet of intermittent streams and 0.359 acres of wetlands to
develop the North General Expansion Project. The design (see attached drawings)calls for the
existing stream to be routed through a 60-inch concrete reinforced pipe approximately 1,600
feet in length installed beneath the fill. As a part of this development,our Asheville Steam
Electric Plant coal ash will be utilized in select portions of the project as structural fill.
As detailed in the attached drawings,the project design will utilize porous material within the
perennial streams, intermittent streams and wetlands in addition to serving as bedding beneath
the 60-inch concrete reinforced pipe. This will allow any water upwelling to flow parallel to the
concrete reinforced pipe.The remainder of the project footprint will be filled with clean soils to
a depth of at least two feet above the top of the 60-inch concrete reinforced pipe. Over this
clean fill, a geosynthetic clay liner(GCL)will be placed. Only above the GCL will coal ash be
utilized as structural fill. The coal ash side slopes will be covered by a minimum of two feet of
clean soils and seeded. The top of the coal ash fill will be covered by six feet of clean soils and
seeded,above which pavement, hangars and other ancillary development will be placed. No
construction is anticipated to encounter the ash fill.
It is our understanding that the water flowing within this 60-inch concrete reinforced pipe is
considered Waters of the State. Our above referenced Ash Distribution Program Permit and the
Airport's 401 water quality certification state that coal ash can be used as structural fill within 50
feet of surface waters with prior approval from the Aquifer Protection Section of the
appropriate Division Regional office.
As the coal ash fill is proposed to be encapsulated between clean soils and a GCL liner, we
believe that the surface waters within the 60-inch concrete reinforced pipe are adequately
protected. We therefore request your approval to use coal ash as structural fill in accordance
Progress Energy Service Company,LLC
P.O.Box 1551
Raleigh,NC 27602

with the details.of the attached drawings. We welcome any questions or discussions you have
in order to expedite our request and ensure the best possible design to protect surface and
ground waters. Please contact Ms.Laurie Moorhead at 828-687-5240 for further questions and
discussions.

Introduction
This document serves as the Annual Inspection Report(Report) required by Condition V.2.of NCDENR
(now NCDEQ) Permit No.WQ0000020(Permit) issued to Duke Energy on September 2, 2015.
Pursuant to the Permit,an annual inspection report shall be submitted on or before December 31 of
each year. Quarterly inspections shall be performed that log observations pertaining to the integrity of
intermediary and permanent caps,structural integrity, erosion,condition of liner systems,stormwater
collection systems and condition of monitoring wells. Quarterly inspections shall contain the following,
at a minimum:
• Date and time of each report;
• Name and title of the inspectors;
• Observation results on structural integrity, erosion, liner systems, integrity of the cap system,
stormwater collection systems,condition of monitoring wells,settlement,subsidence,seepage,
and presence of woody vegetation;
• Description and photo documentation of any pertinent issues such as breach in liner system,
excavations within 3 feet of the liner system,erosion, development of depressions,slope
movement, damage to monitoring wells, and groundwater seepage;
• Any maintenance, repairs,or corrective actions taken;
• An annual engineer's certification of the evaluation on the structural integrity and stability of
the ash fill areas.
Annual Report Summary and Observations
In accordance with the Permit conditions and as outlined in the 2015 Annual Report, Duke Energy
performed regular inspections of the structural fill areas at the Asheville Regional Airport(Airport) in
2016. Duke Energy was issued a Notice of Violation No. NOV-2015-PC-0303 (NOV) on December 2,2015.
As part of the response to the NOV mentioned above,the following schedule was proposed in the 2015
Annual Report for completion of the permanent design, permitting, and construction of repairs and
improvements to Area I and Area IV.
• 60 days to complete permanent designs for Area I and review existing permanent
stormwater management plan for Area IV(March 1,2016)
• 45 days to complete necessary permitting with NCDEQ(April 15, 2016)
• 60 days to complete construction activities on-site(June 15,2016)
Duke Energy agreed to perform monthly inspections until all issues in the NOV were addressed.
Subsequently, quarterly inspections would resume per the permit. Repairs and maintenance of the
items in the NOV were deemed substantially complete after the September monthly inspection.A
quarterly inspection,for Quarter 4,was performed in November.

northeast corner of the property,Area III west of the runway to the north, and Area IV to the west of
the runway and to the south.
Area I &Area IV Improvement Plan
The Area I &Area IV Improvement Plan consisted of construction drawings and erosion and sediment
control measures developed by AVCON. Inc.,the airport's engineering consultant,and Charah,the
airport's construction contractor. Duke Energy engineering reviewed the plans and provided comments
to ensure the plans would meet the requirements of the NOV. The plans were finalized March 1, 2016.
The plans were also forwarded to NCDEQ Division of Water Quality as a courtesy to show the repair plan
was progressing.The final sealed plans are included as Attachment 1 to this report.
AVCON submitted the plans to NCDEQ for Erosion and Sediment Control permitting in March 2016. The
Letter of Approval was received April 20, 2016. Charah began construction of the repairs for Area I on
April 21,2016 and completed repairs on June 15, 2016.Area IV repairs were started in May 2016 and
completed June 30, 2016.Area IV repairs were delayed due to an ongoing construction project in the
vicinity of Area IV.
As part of the July inspection, Duke Energy walked the areas and inspected the repairs with
representatives of Charah and the airport. Duke Energy submitted a letter of completion for the
improvements plan on August 16, 2016.This letter is attached to this report as Attachment 2.
Duke Energy continued to do monthly inspections through September until the Erosion and Sediment
Control Plan was finalized by DEQ. Duke Energy initiated quarterly inspections thereafter.

Area I
The Area I ash fill, completed in the fall of 2010, is an approximately 18-acre fill area on the north end of
the Airport located east of the runway. The fill area is designed to slope north at a 2.5%grade across
the top of the fill area. The outer slope of the fill was built to a 33% (3H:1V)slope. A wetland area,
stormwater structures, and outfalls are located at the north toe of the Area I slope.
There is a 100-foot wide compacted soil core over the length of a 60-inch diameter stormwater pipe that
transects the ash fill. The pipe flows south to north and is part of drainage from the Airport runway
areas. The compacted soil core is to ensure that ash is not located within 50 feet of a stormwater pipe.
Area I is lined with geosynthetic clay liner(GCL) on the bottom. The cap system for the area is a
vegetated compacted soil cover. The top of the fill system with the 2.5%grade is constructed with a 6-
foot thick soil cap. The outer slopes are constructed with a 2-foot thick soil cap as designed. The detail
for the cap is shown in the figure below. The detail shown below is from the drawing set"Asheville
Regional Airport-Fly Ash Beneficial Use Project," issued by Charah, revised December 2007.

Area I Observations
During the last two months of 2015,temporary measures were installed in Area I to divert water,
establish vegetation and prevent further erosion until a final repair plan could be developed.AVCON,
the airport's engineering consultant,was contracted to prepare a permanent repair plan by March 1,
2016 with approval and construction completed by June 15, 2016. Until the plan and repairs could be
completed,the temporary structures were maintained and inspected.
The photos below illustrate the measures taken to reduce erosion and establish vegetation in Area I
after the NOV was issued. Before the repair plan could be implemented,typical conditions as shown in
the photos existed relatively unchanged from January to April.

After clearing vegetation in later 2015, an apparent weep and scarp were noted on the north side of the
access road that forms the toe of the fill area. This area was to be addressed within the repair plan, by
removing unstable material and backfilling and re-grading the area.

good condition. Minor erosion was noted in areas along the south slope as well as some small animal
burrows that would be addressed. The top of the fill had a few minor erosion issues, an area of sparse
vegetation, and a small depression requiring attention. Duke Energy identified these areas in the
monthly reports and provided a list of recommended repairs for each issue to the Airport.
Area I Corrective Actions
A permanent repair plan was approved by NCDEQ in April 2016. Charah began work on the repair plan in
May and completed the work in June.The plan for Area I included re-grading areas to divert
stormwater, install fill to ensure permitted cap thickness and repairing drainage structures.
The pictures below show examples of repair construction.

Area IV
The Area IV ash fill,substantially completed April 1,2015, is located to the west of the Airport
runway. The 28-acre fill area was constructed in three different phases: Phase I, Phase IA, and Phase
2. Area IV is constructed (from bottom to top) with a compacted soil subgrade,geosynthetic clay liner,
and 60-mil geomembrane liner with leachate collection pipes on top of the liner. The leachate collection
system gravity drains to the District.
The cap system is similar to Area III noted above, but it was designed with a 30-mil geomembrane cap.
The soil thickness on the cap is six feet on top and two feet on the side slopes as designed.

Area IV Observations
An inspection in October 2015 identified exposed geomembrane liner along the western slope (but not
exposed ash),areas with over grown vegetation, and several areas of erosion on the slopes. The area
with the exposed cap was filled with soil and a sandbag diversion ring was installed to divert surface
water until a permanent grading plan is developed and implemented. Further inspections ofthe area in
November and December 2015 revealed the temporary measures were successful in diverting water
and avoiding further erosion.
Area IV was included in the AVCON Improvement plan to repair the deficiencies noted above.The areas
were inspected monthly,similar to Area I,to ensure the areas needing repair were not worsening.
The photos below show typical conditions in the area prior to being addressed with the repair plan
design and implementation.

the new runway.
Area IV Corrective Actions
A permanent repair plan was approved by NCDEQ in April 2016. Charah began work on the repair plan in
May and completed the work in June.The plan for Area IV included re-grading areas to divert
stormwater,establishing vegetation, and placement of fill to ensure permitted cap thickness.
Improvement Plans were developed by AVCON,the contractor for the Asheville Airport.The plans were
shared with NCDEQ-Asheville Regional Office in March 2016.An Erosion &Sediment Control Plan
approval was issued to start work May 13, 2016. Charah completed construction in Area IV June 30,

3 September 7,2017 Quarterly
4 Nov.ember 2,2017 Quarterly

Based on observations from the September 7 inspection, NCDEQ Department of Water Resources was
notified of possible exposed ash on the north slope of Area I.Subsequently, DEQ requested additional
information to be submitted as well as additional monitoring of Area I. DEQ issued an official Notice of
Violation (NOV)on November 17, 2017, NOV-2017-PC-0616(Incident#201701440).The NOV outlined a
list of items to be provided in a report by December 29, 2017 (aka, 90-day submittal). Items related to
the NOV and required submittal will not be covered in this Annual Inspection Report.
Duke Energy began making weekly inspections to monitor conditions following the September 7
inspection to monitor Area I and provide feedback to DEQ.The weekly inspections are not summarized
in this Annual Report.Area I matters will be presented under separate cover in response to the NOV and
in the 90-day submittal prepared by Geosyntec.

Area I
The Area I ash fill,completed in the fall of 2010, is an approximately 18-acre fill area on the north end of
the airport, east of the runway.The top of the fill area was designed to slope downward towards the
north at a 2.5%grade.The outer slope of the fill was designed to a 33% (3H:1V)slope.A sediment basin,
stormwater structures, and outfalls are located at the north toe of the Area I slope.
According to information included in the "As Built"Surface Development drawings by Vaughan
Engineering latest revision February 22,2016,there is a 100-foot wide compacted soil core over the
length of a 60-inch diameter stormwater pipe that transects the ash fill.The 60-inch pipe flows south to
north and is part of drainage from the airport runway areas.The compacted soil core was designed to
ensure that ash is not located within 50 feet of a stormwater pipe.
Area I is lined with geosynthetic clay liner(GCL) on the bottom.The cap system for the area is a
vegetated compacted soil cover.The top of the fill area was designed with a 6-foot thick soil cap.The
outer slopes were designed with a 2-foot thick soil cap.The detail for the cap is shown in the figure
below.The detail shown below is from the drawing set"Asheville Regional Airport-Fly Ash Beneficial
Use Project," issued by Charah, revised December 2007.

Area I underwent extensive repairs during 2016. Repairs to the area were completed and finalized in
September 2016.The Annual Report for 2016 showed Area 1 to be in good condition in December 2016
with the re-graded slopes in good condition and having established vegetation.
1st Quarter Inspection-February 23,2017
The first quarterly inspection did not note any structural changes to the fill area.A seep was noted near
the toe in the wetlands and two animal burrows were noted and subsequently repaired.An erosion rill
was noted on the east toe of the slope.

Duke Energy responded to the slough by installing a temporary repair and covering the material and
placing sandbags to divert water during impending tropical storms.The area was eventually repaired by
covering the area with geosynthetic fabric,a sand layer and rip-rap ballast.The repair was intended to
allow water to drain from the slope without having cover material slide or ash release.

Area 3.
This observation was addressed in the first quarter report. Photo 7 from the summary above,shows the
area had been repaired. Duke Energy continued to include the area in its inspections, inspecting the cap
for erosion and integrity issues.
The Area III fill appeared to be in good condition throughout 2017 based on the quarterly inspections.
With the leachate flow ranging from 0-1 gpm, it appears the cap and liner system are performing as
designed.
Area IV
The Area IV ash fill,substantially completed April 1,2015, is located to the west of the airport runway.
The 28-acre fill area was constructed in three different phases: Phase I, Phase IA,and Phase 2.Area IV is
constructed (from bottom to top)with a compacted soil subgrade,geosynthetic clay liner,and 60-mil
geomembrane liner with leachate collection pipes on top of the liner.The leachate collection system
gravity drains to the District.
The cap system is similar to Area III noted above, but it was designed with a 30-mil geomembrane cap.
The soil thickness on the cap is six feet on top and two feet on the side slopes as designed.

Area 1
The Area 1 ash fill, completed in the fall of 2010, is an approximately 18-acre fill area on the north end of
the Airport located east of the runway.The fill area is designed to slope north at a 2.5%grade across the
top of the fill area.The outer slope of the fill was built to a 33%(3H:1V)slope.A wetland area,
stormwater structures, and outfalls are located at the north toe of the Area 1 slope.
There is a 100-foot wide compacted soil core over the length of a 60-inch diameter stormwater pipe that
transects the ash fill.The pipe flows south to north and is part of drainage from the Airport runway
areas.The compacted soil core is to ensure that ash is not located within 50 feet of a stormwater pipe.
Area 1 is lined with geosynthetic clay liner(GCL) on the bottom.The cap system for the area is a
vegetated compacted soil cover.The top of the fill system with the 2.5%grade is constructed with a 6-
foot thick soil cap.The outer slopes are constructed with a 2-foot thick soil cap as designed.The detail
for the cap is shown in the figure below.The detail shown below is from the drawing set"Asheville
Regional Airport-Fly Ash Beneficial Use Project," issued by Charah, revised December 2007.

Area 1 Observations
Area 1 underwent extensive repairs during 2016. Repairs to the area were completed and finalized in
September 2016.The Annual Report for 2016 showed Area 1 to be in good condition in December 2016
with the re-graded slopes in good condition and having established vegetation. In December of 2017 a
portion of the slope was repaired to cover exposed ash and in response to the Notice of Violation (NOV-
2017-PC-0616).The repair included covering the exposed ash with sand, non-woven geotextile and rip-
rap.The repair's dimensions are approximately 130-ft long and 30-ft wide.
1st Quarter Inspection-February 15,2018
The first quarterly inspection did not note any structural changes to the fill area nor exposed ash.Some
minor erosion and wet areas were noted.A scarp noted in previous inspections along the toe of the
bench road.This area was repaired with similar stabilization repair for the north slope. Figures 1 and 2
below show the repaired areas.

This observation was addressed in the 2017 fourth quarter report. Photo 8 from the summary above,
shows the area. Duke Energy continued to include the area in its inspections, inspecting the cap for
erosion and integrity issues.
The Area 3 fill appeared.to be in good condition throughout 2017 based on the quarterly inspections.
With the leachate flow ranging from 0-3 gpm, it appears the cap and liner system are performing as
designed.

Area 4
The Area 4 ash fill,substantially completed April 1,2015, is located to the west of the Airport runway.
The 28-acre fill area was constructed in three different phases: Phase I, Phase IA, and Phase 2.Area 4 is
constructed (from bottom to top)with a compacted soil subgrade,geosynthetic clay liner,and 60-mil
geomembrane liner with leachate collection pipes on top of the liner.The leachate collection system
gravity drains to the District.
The cap system is similar to Area 3 noted above, but it was designed with a 30-mil geomembrane cap.
The soil thickness on the cap is six feet on top and two feet on the side slopes as designed.

The Area 4 fill appeared to be in fair condition throughout 2018 based on the quarterly inspections.
With the leachate flow maintaining 0 gpm readings in each quarter, it appears the cap and liner system
are performing as designed.The erosion and vegetation issues were not addressed adequately in 2018.
Final Observations
The structural fills Area 3 and Area 4 at the Asheville Regional Airport are in overall good condition as
documented in regular inspections by Duke Energy in 2018.The cap and liner systems appear to be
performing as designed as the outfall measurements ranged from 0-3 gpm throughout the year.
Ongoing inspections will ensure the fills continue functioning as designed and maintain the integrity of
the fill structures.
The ongoing issues for Areas III and 4include establishing and maintaining vegetation and continual
maintenance and repair of erosion.As of the final Quarterly Report, dated November 20, 2018,the
following table lists issues to be monitored and recommended actions going into 2019.The tables will
be shared with Asheville Airport maintenance. Duke Energy does not maintain the areas.

Monitoring Wells
In addition to monitoring the surface of the fills,the condition of the monitoring wells were observed
quarterly per the permit. Conditions of the wells were recorded regarding access, casing, caps, labeling,
locks, paint and well pad.All wells as of the final quarterly report are in satisfactory condition with no
issues outstanding.The wells were sampled biannually per the permit in April and November.Additional
wells, MW-06—MW-09,were installed in Area 1 in August 2018.These wells were inspected visually in
the Q4 inspection:They will be added to the quarterly monitoring moving forward.

Dear Mr. Hall,
Please find attached the analytical results for a water sample collected from your water
supply well located at the address referenced above, on February 24, 201.5,.Te samples
were analyzed for sulfate and various metals.Your-water supply well was chosen for
sampling due to its proximity to a coal ash structural fill currently being constructed at the
Asheville Regional Airport.The collection of water samples is a routine matter and not an
indication of impacts to local drinking water supplies.
The following table summarizes the attached analytical results.The results are shown in
units of micrograms of contaminant per liter of water and is approximately equivalent to
part per billion (ppb).
;.
Chloride ~ 250,000 ppb 1,100 ppb
Calcium. 17,000 ppb
Copper 1,300 ppb 1,000 ppb 3.2 ppb
Magnesium , 5,600 ppb
Potassium 3,600 ppb
Sodium 9,500 ppb
Zinc 1,000 ppb 11 ppb
The analytes that were detected are not above the applicable standards and are fairly
typical of groundwater quality in western North Carolina. Nonetheless, a Health Risk
Evaluation (HRE) of the water supply well was performed 'by our toxicologist, Dr. Ken
Rudo. The HRE, which is enclosed, states your drinking water, based on the latest results,
is safe for all household uses including drinking, cooking, washing dishes, bathing,.and

Dear Mr. Kachman,
Please find attached the analytical results for a water sample collected from your water
supply well located at,the address referenced above, on February 9, 2015.The samples
were analyzed for sulfate and various metals.Your water supply well was chosen for
sampling due to its proximity to a coal ash structural fill currently being constructed at the
Asheville Regional Airport.The collection of water samples is a routine matter and not an
indication of impacts to local drinking water supplies.
The following table summarizes the attached analytical results. The results are shown in
units of micrograms of contaminant per liter of water and is approximately equivalent to
part per billion (ppb).

Calcium 12,000 ppb
Copper 1,300 b 1,000 ppb 5.3 ppb
Magnesium 1,700 ppb
Potassium 2,200 ppb
Sodium 7,000 ppb
The analytes that were detected are not above the applicable standards and are fairly
typical of groundwater quality in western North Carolina. Nonetheless, a Health Risk
Evaluation (HRE) of the water supply well was performed by our toxicologist, Dr. Ken
Rudo. 'The HRE, which is enclosed, states your drinking water, based on the latest results,
is safe for all household uses including drinking, cooking, washing dishes, bathing, and
showering.-

Subject: Asheville Airport Well Receptor Survey
Dear Mr. Hall and Ms. Dhar,
The North Carolina Division of Water Resources is conducting a review of private water
supply wells located in close proximity to a coal combustion byproduct (CCB) structural fill
,currently under construction at the Asheville Regional Airport in Buncombe County.The
Division would like permission to sample you water supply well(s) for dissolved metals in
order to establish a baseline or reference point for local groundwater quality.
The request to sample your water supply well is strictly a precautionary measure. The CCB
structural fill project utilizes-an impervious liner and a leachate collection system to
protect the environment. There is no evidence that coal ash is impacting the quality of your
drinking water. .
There is no cost associated with the water sample analysis.A copy of the analytical results
will be provided to you. Please contact me at.[phone] or [e-mail]
to schedule an appointment. I would appreciate your prompt attention to this matter.
Sincerely,
J'

Dear Mr. Phillips,
Please find attached the analytical results for a water sample collected from your water
supply well located at the address referenced above, on October 1, 2014. The samples
were analyzed for thallium,sulfate,and various metals.Your water supply well was chosen
for sampling due to its proximity to a coal ash structural fill currently being constructed at
the Asheville Regional Airport.The collection of water samples is a routine matter and not
an indication of impacts to local drinking water supplies.
The following table summarizes the attached analytical results. Please note that the bolded
values indicate levels above the NC Groundwater Standard, 15A NCAC 2L.0202. The
results are shown in units of micrograms of contaminant per liter of water and is
approximately equivalent to part per billion (ppb).

Because constituents were detected in your water sample above the applicable standard,a
Health Risk Evaluation (HRE) of the water supply was performed by our toxicologist,Dr.
Ken Rudo. The HRE,which is enclosed,makes specific recommendations for use of your
water based on these results.The remaining constituents in your drinking water are typical
for groundwater quality in Western North Carolina.
I will be contacting you shortly to resample your well for lead. If you have any questions
concerning the Health Risk Evaluation,please contact Dr. Ken Rudo at [phone]. If
you have any additional questions or concerns,please contact me at [phone] or

Dear Mr. and Mrs. Pinner,
Please find attached the analytical results for multiple water samples collected from your
water supply well located at the address referenced above, on October 1, 2014 and October
6, 2014. The samples were analyzed for thallium, sulfate, fecal coliform bacteria,total
coliform bacteria, and various metals.Your water supply well was chosen for sampling due
to its proximity to a coal ash structural fill currently being constructed at the Asheville
Regional Airport. The collection of water samples is a routine matter and not an indication
of impacts to local drinking water supplies:
The following table summarizes the attached analytical results.The results are shown in
units of micrograms of contaminant per liter of water and is approximately equivalent to

Dear Mr. Eaton and Ms. Roach,
Please find attached the analytical results for a water sample collected from your water
supply well located at the address referenced above, on October 1, 2014. The samples
were analyzed for thallium, sulfate,and various metals.Your'water supply well was chosen
for sampling due to its proximity to a coal ash structural fill currently being constructed at
the Asheville Regional Airport. The collection of water samples is a routine matter and not
an indication of impacts to local drinking water supplies.
The following table summarizes the attached analytical results. Please note that the bolded
values indicate levels above the NC Groundwater Standard, 15A NCAC 2L.0202.The
results are shown in units of micrograms of contaminant per liter of water and is
approximately equivalent to part per billion (ppb).

Dear Mr. and Mrs:Kachman,
The North Carolina Division of Water Resources is conducting a review of private water
supply wells located in close proximity to a coal combustion byproduct (CCB) structural fill
currently under construction at the Asheville Regional Airport in Buncombe County. The
Division would like permission to sample you water supply well(s) for dissolved metals in
order to establish a baseline or reference point for local groundwater quality.
The request to sample your water supply well is strictly a precautionary measure. The CCB
.structural fill project utilizes an impervious liner and a leachate collection system to .
protect the environment. There is no evidence that coal ash is impacting the quality of your
drinking water.
There is no cost associated with the water sample analysis.A copy of the analytical results
will be provided to you. Please contact me at(828) 296-4681 or [e-mail]
to schedule an appointment. I would appreciate your prompt attention to this matter.

Dear Mr. Mack,
On January 25, 2010, personnel from the Aquifer Protection Section's Asheville
Regional Office collected a groundwater sample from your water supply well located at 5
Hidden Creek Drive in Buncombe County. This sample was analyzed for chloride, sulfate,
nitrate, nitrite and 18 different metals. A copy of the laboratory analysis is included with this
letter.
Laboratory results indicate no detections for sulfate, nitrite, antimony, arsenic, barium,
beryllium, cadmium, chromium, copper, iron, lead, mercury, manganese, nickel, selenium, and
thallium. However, there are trace amounts of nitrate, magnesium, sodium and zinc. A brief
explanation of each analyte present is given below:
• Chloride was detected at a concentration of 2.8 mg/I. Chloride.is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of chloride at 250 mg/I. The level of
chloride in your water supply well is below the maximum contaminate level.
• Nitrate was detected at a concentration of 0.11 mg/I. Potential sources of nitrate can
include septic systems, animal waste, commercial fertilizer, and decaying organic
matter. North Carolina has established the maximum contaminate level for human
consumption of nitrate at 10 mg/I. The level of nitrate in your water supply are well is
below the maximum contaminate level.
• Magnesium was detected at a concentration of 0.45 mg/I. Magnesium is a naturally
occurring element that is abundant in local rocks and soils. North Carolina has not
established a maximum contaminate level for magnesium.
• Sodium was detected at a concentration of 10 mg/I. Sodium is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has not established a
maximum contaminate level for sodium. U.S. Environmental Protection Agency has
established a dietary recommendation for sodium in water at less than 20 mg/I. The level
of sodium in your water supply well is below the dietary recommendation.
• Zinc was detected at a concentration of 0.024 mg/I. Zinc is a naturally occurring element

that is abundant in local rocks and soils. North Carolina has established the maximum
contaminate level for human consumption of zinc at 1 mg/I. The level of zinc in your
water supply are well is below the maximum contaminate level.
There may be a possibility that the Division will contact you again in year to perform a
follow up sampling of your water supply well. I appreciate your willingness to participate in this
baseline groundwater investigation. If you have any questions concerning your groundwater

Dear Mr. Paz,
On January 25, 2010, personnel from the Aquifer Protection Section's Asheville
Regional Office collected a groundwater sample from your water supply well located at 18
Hidden Creek Drive in Buncombe County. This sample was analyzed for chloride, sulfate,
nitrate, nitrite and 18 different metals. A copy of the laboratory analysis is included with this
letter.
Laboratory results indicate no detections for sulfate, nitrite, antimony, arsenic, barium,
beryllium, cadmium, chromium, copper, iron, lead, mercury, manganese, nickel, selenium,
thallium, and zinc. However, there are trace amounts of chloride, nitrate, magnesium, and
sodium. A brief explanation of each analyte present is given below:
• Chloride was detected at a concentration of 2.6 mg/I. Chloride is a. naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of chloride at 250 mg/l. The level of
chloride in your water supply well is below the maximum contaminate level.
• Nitrate was detected at a concentration of 0.58 mg/I. Potential sources of nitrate can
include septic systems, animal waste, commercial fertilizer, and decaying organic
matter. North Carolina has established the maximum contaminate level for human
consumption of nitrate at 10 mg/I. The level of nitrate in your water supply are well is
below the maximum contaminate level.
• Magnesium was detected at a concentration of 1.5 mg/I. Magnesium is a naturally
occurring element that is abundant in local rocks and soils. North Carolina has not
established a maximum contaminate level for magnesium.
• Sodium was detected at a concentration of 7.8 mg/I. Sodium is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has not established a
maximum contaminate level for sodium. U.S. Environmental Protection Agency has
established a dietary recommendation for sodium in water at less than 20 mg/I. The level
of sodium in your water supply well is below the dietary recommendation.

Estimado Sr. Paz,
El 25 de enero del 2010, personal de la Secci6n de Protecci6n de Acuiferos de la
Oficina Regional de Asheville, tomb muestras de agua subterranea de su pozo localizado en
18 Hidden Creek Drive, condado de Buncombe. Estas muestras fueron analizadas para
cloruro, sulfato, nitrato, nitrito y 18 diferentes metales. Una copia del analisis del laboratorio
esta incluida con esta carta.
Los resultados de laboratorio indicaron no detectado para sulfato, nitrito, antimonio,
arsenico, bario, berilio, cadmio, cromo, cobre, hiero, plomo, mercurio, magnesio, nfquel,
selenio, talio, y zinc. Sin embargo, se encontraron on la muestra, rastros de cloruro, nitrato,
magnesio, y sodio. Una breve explicaci6n de los contaminantes encontrados en el analisis es
dada abajo:
• El cloruro detectado en su pozo esta en una concentraci6n de 2.6 mg/l. El cloruro es un
elemento que se encuentra naturalmente en abundancia en rocas y suelo local. Carolina
del Norte ha establecido un nivel maximo de cloruro permitido para el consumo humano
de 250 mg/l. El nivel de cloruro en su pozo se encuentra por debajo de este nivel.
• El nitrato detectado en su pozo esta en una concentracion de 0.58 mg/I. Las fuentes
potenciales de contaminaci6n del nitrato pueden incluir sistemas septicos, desechos de
animates, fertilizantes comerciales, y descomposici6n de la materia organica. Carolina
del Norte ha establecido un nivel maximo de nitrato permitido para el consumo humano
de 10 mg/l. El nivel de nitrato en su pozo se encuentra por debajo de este nivel.
• El magnesio detectado en su pozo esta en una concentracion de 1.5 mg/l. El magnesio
es un elemento que se encuentra naturalmente en abundancia en rocas y suelo local.
Carolina del Norte no ha establecido un nivel maximo de magnesio permitido para el
consumo humano.
• El sodio detectado en su pozo esta en una concentracion de 7.8 mg/I. El sodio es un
elemento que se encuentra naturalmente en abundancia en rocas y suelo local. Carolina
del Norte no ha establecido un nivel maximo de sodio permitido para el consumo
humano. Sin embargo, la Agencia de Protecci6n Ambiental Federal ha establecido una
recomendaci6n alimenticia para el sodio en el agua de menos de 20 mg/l. El nivel de
sodio en su pozo esta por debajo de la recomendaci6n alimenticia.

Existe la posibilidad que la Division to contacte a usted nuevamente este ant para
realizar muestras de seguimiento en su pozo. Apreciamos su buena voluntad de
participar en esta investigaci6n para establecer niveles en aguas subterraneas. De
usted tener alguna pregunta acerca de su calidad de agua subterranea no vacile en
Ilarnarme al 296-4500 o escribirme a mi correo electronico brett.lavertyCaDncdenr.gov.

Dear Mr. Carr,
On January 25, 2010, personnel from the Aquifer Protection Section's Asheville
Regional Office collected a groundwater sample from your water supply well located at 12
Hidden Creek Drive in Buncombe County. This sample was analyzed for chloride, sulfate,
nitrate, nitrite and 18 different metals. A copy of the laboratory analysis is included with this
letter.
Laboratory results indicate no detections for sulfate, nitrite, antimony, arsenic, barium,
beryllium, cadmium, chromium, lead, mercury, manganese, nickel, selenium, and thallium.
However, there are trace amounts of chloride, copper, iron, nitrate, magnesium, sodium and
zinc. A brief explanation of each analyte present is given below:
• Chloride was detected at a concentration of 4.3 mg/I. Chloride is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of chloride at 250 mg/l. The level of
chloride in your water supply well is below the maximum contaminate level.
• Copper was detected at a concentration of 0.06 mg/I. Copper is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of copper at 1 mg/I. The level of
copper in your water supply well is below the maximum contaminate level.
• Iron was detected at a concentration of 0.08 mg/l. Iron is a naturally occurring element
that is abundant in local rocks and soils. North Carolina has established a maximum
contaminate level for human consumption of iron at 0.3 mg/I. The level of iron in your
water supply well is below the maximum contaminate level.
• Nitrate was detected at a concentration of 1.40 mg/l. Potential sources of nitrate can
include septic systems, animal waste, commercial fertilizer, and decaying organic
matter. North Carolina has established the maximum contaminate level for human
consumption of nitrate at 10 mg/I. The level of nitrate in your water supply are well is
below the maximum contaminate level.

Dear Ms. Lipinski,-
On February 15, 2010, personnel from the Aquifer Protection Section's Asheville
Regional Office collected a groundwater sample from your water supply well located at 10
Hidden Creek Drive in Buncombe County. This sample was analyzed for chloride, sulfate,
nitrate, nitrite and 18 different metals. A copy of the laboratory analysis is included with this
letter.
Laboratory results indicate no detections for sulfate, nitrite, antimony,. arsenic, barium,
beryllium, cadmium, chromium, lead, mercury, nickel, selenium, thallium, and zinc. However,
there are trace amounts of chloride, iron, manganese, nitrate, magnesium, and sodium. A brief
explanation of each analyte present is given below:
• Chloride was detected.at a concentration of 5.3 mg/I. Chloride is anaturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of chloride at 250 mg/l: The level of
chloride in your water supply well is below the maximum contaminate level.
• Iron was detected at a concentration of 2.40 mg/l. Iron is a naturally occurring element
that is abundant in local rocks and soils. North Carolina has established the maximum
contaminate level for human consumption of iron at 0.3 mg/l. Despite exceeding the
maximum contaminate level, elevated iron does not pose a health risk. It is quite
common to find elevated levels of iron and manganese in our region's water supply
wells.
• Manganese was detected at a concentration of 0.04 mg/I. Manganese is a naturally
occurring element that is abundant in local rocks and soils. North Carolina has
established the maximum contaminate level for human consumption of manganese at
0.05 mg/l. The level of manganese in your water supply well is below the maximum
contaminate level.
• Nitrate was detected at a concentration of 1.30 mg/l. Potential sources of nitrate can
include septic systems, animal waste, commercial fertilizer, and decaying organic
matter. North Carolina has established the maximum contaminate level for human

consumption of nitrate at 10 mg/I. The level of nitrate in your water supply are well is
below the maximum contaminate level.
• Magnesium was detected at a concentration of 1.6 mg/I. Magnesium is a naturally

• Sodium was detected at a concentration of 6.7 mg/I. Sodium is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has not established a
maximum contaminate level for sodium. U.S. Environmental Protection Agency has
established a dietary recommendation for sodium in water at less than 20 mg/I. The level
of sodium in your water supply well is below the dietary recommendation.
There may be a possibility that the Division will contact you again in year to perform a
follow up sampling of your water supply well. I appreciate your willingness to participate in this
baseline groundwater investigation. I have taken the liberty of including some information on
iron and manganese in water supply wells. If you have any questions concerning your

At the time the sample was collected,iron was present and above the applicable
standard.The remaining anlaytes are below the applicable standards and within a normal
range for water supply wells in western North Carolina.
The Aquifer Protection Section is planning to resample water supply wells in the
Hidden Creek Community in 2015. I have taken the liberty of including a fact sheet on iron
in groundwater. If you have any questions regarding the results please contact me at

Dear Ms. Hare,
On March 8, 2010, personnel from the Aquifer Protection Section's Asheville Regional
Office collected a groundwater sample from your water supply well located at 3 Hidden Creek
Drive in Buncombe County. This sample was analyzed for chloride, sulfate, nitrate, nitrite and
14 different metals. A copy of the laboratory analysis is included with this letter.
Laboratory results indicate no detections for arsenic, barium, cadmium, chromium, iron,
lead, manganese, mercury, nickel, nitrite, selenium, and sulfate. However, there are trace
amounts of chloride, copper, magnesium, nitrate, sodium, and zinc. A brief explanation of each
analyte present is given below:
• Chloride was detected at a concentration of 1.7 mg/l. Chloride is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of chloride at 250 mg/I. The level of
chloride in your water supply well is below the maximum contaminate level.
• Copper was detected at a concentration of 0.005 mg/l. Copper is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has established a
maximum contaminate level for human consumption of copper at 1 mg/l. The level of
copper in your water supply well is below the maximum contaminate level.
• Magnesium was detected at a concentration of 2.1 mg/l. Magnesium is a naturally
occurring element that is. abundant in local rocks and soils. North Carolina has not
established a maximum contaminate level for magnesium.
• Nitrate was detected at a concentration of 1.1 mg/l. Potential sources of nitrate can
include septic systems, animal waste, commercial fertilizer, and decaying organic
matter. North Carolina has established the maximum contaminate level for human
consumption of nitrate at 10 mg/l. The level of nitrate in your water supply are well is
below the maximum contaminate level.
• Sodium was detected at a concentration of 5.9 mg/l. Sodium is a naturally occurring
element that is abundant in local rocks and soils. North Carolina has not established a
maximum contaminate level for sodium. U.S. Environmental Protection Agency has

established a dietary recommendation for sodium in water at less than 20 mg/I. The level
of sodium in your water supply well is below the dietary recommendation.
• Zinc was detected at a concentration of 0.025 mg/l. Zinc is a naturally occurring element
that is abundant in local rocks and soils. North Carolina has established the maximum
contaminate level for human consumption of zinc at 1 mg/l. The level of zinc in your
water supply are well is below the maximum contaminate level.
There may be a possibility that the Division will contact you again in year-to perform a
follow up sampling of your water supply well. I appreciate your.willingness to participate in this
baseline groundwater investigation. If you have any questions concerning your groundwater
quality do not hesitate to call me at 296-4500 or at brett.lavertyCa)-ncdenr.gov.

that is abundant in local rocks and soils. North Carolina has established the maximum
contaminate level for human consumption of zinc at 1 mg/I. The level of zinc in your
water supply are well is below the maximum contaminate level.
There may be a possibility that the Division will contact you .again in year to perform a
follow up sampling of your water supply well. I appreciate your willingness to participate in this
baseline groundwater investigation. If you have any questions concerning your groundwater
quality do not hesitate to call me at 296-4500 or at brett.lavertva-ncdenr.gov.
