Dear Mr. Thornburg,
The Wastewater Irrigation System Permit for the City of Raleigh Wrenn Road Spray Irrigation Facility,
Permit No. WQ0002708 is set to expire on June 30, 2020 and is due for renewal. In accordance with
NCDENR DWR non -discharge permit renewal requirements, the City of Raleigh is submitting the
enclosed Non -Discharge Permit Renewal request package within six months of the permit expiration date
to request renewal of Permit No. WQ0002708.
The enclosed permit renewal request submittal package includes the following:
• A signed copy of completed and executed Non -Discharge System Renewal Application (Form
NDSR 08-19). (Attachment A)
• The most recently issued permit, dated July 14, 2015. (Attachment B)
• A report prepared by HDR, NC 540 Impacts on Raleigh Wrenn Road Facility, which describes the
anticipated loss of spray irrigation area sustained by the Wrenn Road Facility. (Attachment C)
• An updated site map for the facilities, including a general overall location map and multiple site
plans that have been prepared for the Spray Irrigation Modifications Project. (Attachment D)
The current permit includes a statement regarding the reduction of setbacks to residences that are part of
the Buffaloe Preserve LLC subdivision. The setbacks were reduced to 200 feet per setback waiver
allowance in 15A NCAC 02T .0506(d). The City would like to continue with this setback. We do not
believe the data in the table in Section IV of the permit application form is necessary.
As part of the previous permit requirements, the City has installed four groundwater monitoring wells at
various locations approved by NC DEQ that are at or near the Wrenn Road Facility. The purpose of these
wells is to evaluate background concentrations of manganese, iron and arsenic above 15A NCAC 02L
standards. Per conversations with NC DEQ, modeling may be required after the sampling campaign is
completed.
It is anticipated that, NC 540 will be expanded on a portion of the Wrenn Road Spray Irrigation Facility.
Potential changes to the facility as a result of this project have been previously discussed with NC DEQ
during initial conversations for this permit renewal and as part of the City's Groundwater Monitoring Plan
for the Wrenn Road facility Wastewater Irrigation System Memorandum submittal to NC DEQ. The NC
540 project is currently in the design phase, but it is anticipated that there will be impacts to spray
irrigation fields 2A and 3B as a result of construction. Potential impacts may include a loss of 8.3 acres of
irrigable land and modifications to spray field operations. The attached NC 540 Impacts on Raleigh
Wrenn Road Facility report prepared by HDR provides a detailed analysis of the anticipated impacts.
Changes to facility operations from NC 540 will be addressed by submitting a separate application for a
revised permit when design is complete.

Should you have any questions regarding the permit renewal request, please feel free to contact me at
[phone].

Please see Condition III.9 prohibiting public access to the treatment and disposal site.
Because a new subdivision and high school are being constructed in the immediate vicinity, it is
recommended gated access to the facilities be installed to the Wrenn Road entrance and additional
fencing on the site.
As pm t of the application, Permittee has requested establishment of background
concentrations for arsenic, iron, and/or manganese above the groundwater standards contained in
Attachment C. The City has obtained monitoring data that suggests that background concentrations of
arsenic, iron and manganese occur at levels greater than the groundwater standards established in 15A
NCAC 02L. Per 15A NCAC 02L .0202(b)(3), the Director shall determine the groundwater standard to
be the natural occurring concentrations. Please coordinate Nvith the Raleigh Regional Office to ensure that
appropriate monitoring data is obtained to support a background concentration determination. Also,
consider the following guidance material in determining background concentrations:
1. Aquifer Protection Section Policy for Metals Determinations Required by Title 15A, North
Carolina Administrative Code, Subchapter 2L (May, 2013)
[http:!/portaLnedenr.org/e/document_I ibrarydget_fi le?unid=2fcae529-e6fe-46a6-aa29-

Until a background concentration can be established, and the permit modified to reflect site -specific
groundwater standard, the Division will use its enforcement discretion on reported monitoring data for
arsenic, iron and manganese. Please note additional footnotes in Attachment C that recognizes this
process.
If any parts, requirements or limitations contained in this permit are unacceptable, the Permittee
has the right to request an adjudicatory hearing upon written request within 30 days following receipt of
this permit. This request shall be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings at 6714 Mail
Service Center, Raleigh, NC 27699-6714. Unless such demands are made, this permit shall be final and
binding.

Executive Summary
Executive Summary
The City of Raleigh Public Utilities Department (City) is seeking to quantify the impacts to its
Wrenn Road Facility from construction of the NC 540 Triangle Expressway Southeast Extension
by the North Carolina Department of Transportation (NCDOT), Federal Highway Administration
(FHWA) and North Carolina Turnpike Authority (NCTA) (Figure ES- 1). The Wrenn Road Facility
site will be impacted in at least three ways:
• Sprayfield irrigated area and other physical infrastructure for the treatment facility are lost
at the southern end of the site, either directly (taken by NCDOT for Expressway right of
way or for a stormwater drainage easement) or indirectly (state -required setbacks
between Wrenn Road Facility sprayfields and property lines)
• Irrigation system pumping systems and controls are impacted; modified pumping systems
and controls programming will be required
• New infrastructure will need to be constructed at another location to replace the treatment
capacity lost due to NCDOT's project
Other impacts may also occur, including the lost opportunity to utilize the southern end of the site
for additional wastewater pumping infrastructure and the value of the lost land area itself.

Executive Summary
data was supplemented by discussions and data provided by the City of Raleigh Public Utilities
Department staff.
The Wrenn Road Facility receives water treatment process residuals from the Dempsey E. Benton
Water Treatment Plant through a 16-inch influent force main. Liquid from the residuals is spray -
applied to the site's 14 irrigation zones. Capacity impacts from the NC 540 project occur in spray
irrigation zones 2A and 3B, in the southeast portion of the site. These impacts are effectively the
same whether or not the specified setback is 50-ft or 150-ft from the NC 540 right of way because
of the operational requirements and how the setbacks intersect the sprayfield grid system.
With a 50-ft or 150-ft setback, irrigation zone 2A will lose approximately 7.1 acres of its original
20.2 acres irrigated area; zone 3B will lose approximately 4.3 acres of its 16.7 acres of irrigated
area. The total loss of approximately 11.4 acres of irrigation is 4.3 percent of the total 268.68
irrigated acres at the site.
The conceptual level opinion of probable project cost for replacement of treatment capacity at the
Wrenn Road Facility ranges from $2.5 million to $9.2 million. A new location offsite will be needed
to replace the lost capacity; the wide range of cost opinion presented reflects the difference in
expected costs between an adjacent site and a site 5 miles away.
The other factors in the significant uncertainty of the probable project cost opinion are lack of site -
specific data for the capacity replacement site, such as soil conditions, agronomic rates for
irrigation, potential underground utility conflicts, property acquisition requirements and the route
of a pipeline between the Wrenn Road Facility and future replacement site. Property values for
suitable size parcels, for both fee -simple acquisition and temporary or permanent easements, are
also uncertain in this developing area. The City's ability to acquire additional land is not
guaranteed, nor is the ability to permit additional off -site irrigation lands. The cost estimates fall
within the Association for the Advancement of Cost Engineering (AACE) International definition
of a Class 5 industry standard for cost opinions at this stage of the project definition.

Introduction
Introduction
Background
Construction of Interstate Highway 540 (1-540) and North Carolina Highway 540 (NC 540), a
perimeter loop around Raleigh, began in the early 1990s in response to continued strong
population growth in Raleigh, Wake County, and the Research Triangle region. Construction has
been completed on approximately 41 miles of expressway between I-87/US 64/US 264 near
Knightdale, in eastern Wake County, around the neighborhoods of north Raleigh, through an 1-40
interchange near RDU Airport, to NC Highway 55 south of Apex. Based on projected future
regional transportation needs to reduce traffic congestion in the region during peak travel periods
and to improve linkages throughout the regional roadway network, the North Carolina Department
of Transportation (NCDOT), Federal Highway Administration (FHWA) and North Carolina
Turnpike Authority (NCTA) have collaborated to plan for the completion of the 1-540/NC 540
perimeter loop, joining the current terminal ends of the Triangle Expressway and providing
interchanges at US 401 South between Fuquay Varina and Garner, 1-40 South and US 70.
NCDOT, FHWA, and NCTA collaborated on a siting study and evaluation of environmental
impacts. This process is documented in their Final Environmental Impact Statement (FEIS) for
the Complete 540 Triangle Expressway Southeast Extension, completed in December 2017. The
NC 540 extension will be constructed along a route that will cross the southeast portion of the
Wrenn Road Facility.
The Wrenn Road Facility was constructed as a wastewater treatment facility by the Town of
Garner and has been operated by the City since the merger of Garner's water and wastewater
utilities with Raleigh in 2001. The function of Wrenn Road Facility is described as follows on the
City's website:
The Wrenn Road Facility, located in Garner, became a City asset upon utility system merger
agreement with the Town of Garner. Consisting of over 600 acres of fields and woodlands, the
facility was originally used to treat wastewater collected from the sewer system serving most of
the Garner area. The facility has not received waste from the sewer system since 2008, when all
wastewater flow was permanently redirected to the Neuse River Resource Recovery Facility.
Operations at this site have since been repurposed for the management of residuals generated by
operation of the Dempsey E. Benton Water Treatment Plant. These residuals are composed of
the lake sediments and other particles that are removed from the water during the production of
potable water. Water plant residuals are currently land applied and irrigated onto hay fields, and
hay is baled and sold to local area farmers.

HDR Engineering, Inc. of the Carolinas (HDR) developed this technical memorandum to
summarize the findings from a preliminary evaluation of the NC 540 project's impact on the Wrenn
Road Facility, based on its analysis, including discussions and data provided by City of Raleigh
Public Utilities Department staff and the NCDOT NC 540 Design -Build Team.

Impact Analysis
Project Goals
HDR performed a desktop review of available information associated with the Wrenn Road
Facility's infrastructure and operations and NC 540 alignment as provided by NCDOT's Design -
Build Team. The City's goal is to quantify the impacts on the facility by the alignment of NC 540,
in terms of lost treatment capacity, and the costs to replace this capacity at another suitable
location, including:
1. Quantify physical infrastructure impacted by NC 540, either from direct impacts (right of
way [ROW] and stormwater drainage easements) or indirect impacts (irrigation area
setback requirements)
a. Communicate with the North Carolina Department of Environmental Quality
(NCDEQ) Division of Water Resources (DWR) to identify the expected setback for
Wrenn Road Facility's sprayfields from NC 540 ROW to comply with state permits.
b. Map the proposed NC 540 ROW boundary with the Wrenn Road Facility
infrastructure and overlay the required setback from the ROW line.
c. Estimate loss of irrigated area and impact on the Wrenn Road Facility treatment
capacity.
d. Quantify irrigation system pumping and controls logic impacts resulting from the
proposed loss of irrigated area and infrastructure.
2. Describe high-level requirements to replace impacted treatment capacity
3. Estimate the replacement value of the impacted infrastructure
Impact Analysis
Current Operation
The Wrenn Road Facility receives residuals of the water treatment process from the Dempsey E.
Benton Water Treatment Plant (DEBWTP) through a 16-inch influent force main. Spray irrigation
application on the Wrenn Road Facility's 268.68 acres occurs by pumping from two onsite lagoons
to sprinklers in 14 irrigation zones (e.g., zones 1A, 1 B, 2A, 2B, 3A, 3B, 4A, 4B, 5A, 5B, 6A, 6B,
7A, 7B). The on -site pump station includes four 100 HP pumps with variable frequency drives.
The required flow rate to each of the zones has been balanced, with the flow rate and irrigation
time designed to match the seasonal agronomic rate which can be utilized by the irrigated hay
crop and trees. Multiple irrigation zones can be irrigated simultaneously.
Table 1 summarizes the current permit limits for the Wrenn Road Facility (NCDWR Permit No.
WQ0002708, Attachment A; current permit was issued July 14, 2015). The permit limits define
irrigated acreage and yearly maximum inches of liquid which can be applied to each zone; the
yearly maximum number of gallons which can be applied to each zone was not defined in the
permit but can be calculated from the data provided, and is also shown in Table 1. The permit
references the Wrenn Road Facility capacity of 704,618 gallons per day (gpd) of DEBWTP
residuals, which would be equivalent to a total annual application of 257.2 million gallons.

TOTAL
268.68
The entire Wrenn Road Facility exceeds 600 acres, of which 268.68 acres are irrigated. The
remainder of the site is used for the required setbacks, buffer areas, lagoons, roads, and
maintenance and office facilities. The variability in the permit's limits on hourly application rate
and yearly maximum application is due to agronomic analysis of differences in site conditions
between the zones, including soil series, topography and crop type.
The Wrenn Road Facility's design enables flexible operation to respond to current conditions so
that agronomic application rates are not exceeded for the spray zones. Operations staff monitor
weather and soil conditions and variations in residuals flow rate and adjust application schedules
accordingly. The onsite lagoon storage permits the City to pause irrigation on days when ground
conditions are not favorable.
As of 2019, the average day flow through the Wrenn Road Facility is approximately 309,000 gpd.
Continued growth in customer water demands are expected to drive increases in DEBWTP water
production, with corresponding increases in residuals flows toward Wrenn Road Facility capacity
limits.
Physical Infrastructure Impacted By NC 540
The Wrenn Road Facility NC 540 Impacts analysis was completed based on the identified project
goals and preliminary evaluation of the proposed alignment of NC 540 across the site, as provided
by NCDOT's Design -Build Team. HDR performed a desktop review of the estimated project
impacts and reviewed existing infrastructure, existing survey information, limited information on
underground and above -ground utilities, Geographic Information System (GIS) data and other
factors potentially influencing NC 540 project impacts.

Impact Analysis
NCDWR Guidance Regarding Setbacks
Subchapter 15A 2T of the North Carolina Administrative Code (NCAC) — Waste Not Discharged
to Surface Waters - governs permits for waste management systems that do not discharge to
surface waters. Section 15A NCAC 2T.0500 addresses operational requirements for wastewater
spray irrigation systems like the Wrenn Road Facility, including setbacks. Setbacks are defined
as the horizontal separation between the sprinkler irrigation system and various physical features
such as buildings, road right of ways, property lines, and water bodies.
Subsection .0506 requires 50-ft setbacks for sprinkler irrigation systems from road rights of way
and 150-ft setbacks from each property line. HDR verbally confirmed these set -back requirements
with NCDWR's Tessa Monday, Environmental Engineer III, and was advised that a 50-ft setback
would be required from the new NC 540 ROW line. There is a potential risk that in the future the
City is held to the 150-ft property line setback in place of the 50-ft right of way setback. Because
of this potential, an analysis was performed to estimate impacts from both 50-ft and 150-ft
setbacks from the ROW. The analysis shows effectively the same impact because of the
operational requirements and how the setbacks intersect the sprayfield grid system.
Project Impacts to Irrigated Area
HDR used GIS mapping to overlay the proposed NC 540 alignment on the Wrenn Road Facility,
to determine the direct impacts of the Expressway ROW and stormwater drainage easement
taking, and to evaluate the indirect impacts resulting from the additional 50-ft or 150-ft setback
from the ROW imposed by the state's 2T regulations.
Figures 1 and 2 illustrate the area impacted by the NC 540 project. Figure 1 shows the entire
Wrenn Road Facility, while Figure 2 focuses on the impact area for the 50-ft and 150-ft setback
respectively. Capacity impacts occur in irrigation zones 2A and 3B, in the southeast portion of the
site.
With a 50-ft or 150-ft setback, irrigation zone 2A will lose approximately 7.1 acres of the original
20.2 acres of the irrigated area due to the NC 540 project; zone 3B, with 16.7 acres of spray
irrigation, will lose approximately 4.3 acres. This is a combined loss of approximately 11.4 acres
of Wrenn Road Facility's total 268.68 irrigated acres.
At the Wrenn Road Facility's design irrigation rates for each zone, this loss of irrigation area is
estimated to be equivalent to a 5.6 million gallon per year (mg/y) loss in treatment capacity for
zone 2A and a 3.2 mg/y capacity loss for zone 3B. Based on permit spray application limits, Wrenn
Road's overall average day capacity would reduce by 3.7 percent (681,000 gpd) with a 50 or 150-
ft. setback. These losses are experienced in 2 of the 14 irrigation areas.
Direct and indirect impacts are measured in terms of infrastructure loss and lost irrigation capacity.
Infrastructure impacts include the piping (both mains and smaller irrigation system lines), valves
and sprinkler heads for the area lost to irrigation — which could not be relocated and reused
elsewhere — as well as changes to the service requirements for the irrigation system's pumps and
programmed control system. Table 3 summarizes Wrenn Road Facility property loss and irrigation
capacity impacts estimated to result from the NC 540 project. Attachment B includes supporting
data for the impact assessment.

Impact Analysis
Irrigation System Pumping and Controls Logic Impacts
When the Wrenn Road Facility irrigated area is reduced by the NC 540 project, the City will be
required to make some changes to the site's pumping system and irrigation control system. With
a 50-ft or 150-ft setback, the annual average day volume to irrigation zones 2A and 3B will be
reduced, respectively, to 35,809 gallons (35.2% reduction) and 40,678 gallons (25.8%).
Significant seasonal variations exist in application flow rates. These modifications can be
accommodated by programming modifications to the variable frequency drives and the irrigation
system controls logic for these zones.
Mitigating for Loss of Infrastructure and Treatment Capacity
Based on the impacts described above, the City will experience a real loss of infrastructure and
irrigation capacity with either the 50-ft or 150-ft setback. A financial value can be associated with
this impact based on infrastructure losses and costs to restore Wrenn Road Facility's capacity.
HDR's preliminary opinion of the probable costs of these impacts is discussed in the following
section.
The City's water service area is expected to continue growing at a strong rate through the planning
horizon, and the City cannot sustain the loss of the Wrenn Road Facility's treatment capacity
resulting from the construction of NC 540. It will be necessary to offset the lost treatment
capacity at a nearby available parcel by constructing a pipeline from the pump station and
irrigation infrastructure (sprinklers, valves, etc.). Therefore, the cost opinion in the following
section will incorporate replacement costs for the infrastructure and irrigation capacity impacts.
The elements required to mitigate for the loss of infrastructure and treatment capacity are:
■ Parcel of land area comparable in size to the land taken for the project, located adjacent
to the current site if possible to minimize pumping costs between the Wrenn Road Facility
and new irrigated areas. However, if an adjacent site cannot be acquired, a more remote
site several miles from the Wrenn Road Facility could be utilized.
■ Soil types that are at least comparable to the soil types found in the impacted portions of
zones 2A (Granville, Wedowee, Chewacla and Wehadkee sandy loams, and Fuquay
loamy sand) and 3B (Wedowee sandy loams). Further details are provided in Attachment
B.
■ Irrigation infrastructure (piping, valves, sprinkler heads) sufficient for the treatment
capacity to be replaced at a new location.
■ Modifications to pumping facilities and control logic as required to serve the new irrigation
facilities. A dedicated pump station may be required to convey flows to an offsite sprayfield
location.
■ Depending on the site location, cellular or radio communication may be necessary for the
irrigation control system.
■ Monitoring wells for the new irrigation facilities, as required to comply with state -issued
permits.
• Site improvements for the new irrigation facilities, including security fencing, gravel roads,
and site lighting.

Preliminary Project Opinion of Probable Costs
Preliminary Project Opinion of Probable Costs
Capacity Replacement Cost Opinion
The preliminary opinion of probable cost for replacement of treatment capacity at the Wrenn Road
Facility ranges from $2.5 million to $9.2 million for a 50-ft or 150-ft setback. The project cost
opinion for irrigation capacity replacement is shown in Table 4. The opinion confirms to the
Association for the Advancement of Cost Engineering (AACE) International definition of a Class
5 industry standard for cost opinions at this stage of the project definition. Attachment C contains
project cost opinion details.

b Property acquisition and easement acquisition costs per acre are based on a property valuation of larger parcels in
the vicinity of the Wrenn Road Facility.
° Construction cost opinion includes contractor overhead and profit, mobilization/demobilization and other applicable
charges
The opinion of probable project cost contains significant uncertainty, which is attributed to a range
of factors including lack of site -specific data on a replacement site for the lost capacity, such as
soil conditions, agronomic rates for irrigation, potential underground utility conflicts and property
acquisition requirements. This type of information is valuable for understanding the potential
changes that could occur to cost estimates as more detailed project information is developed
during the design phase. The location of a replacement treatment site and the route of a pipeline
11

City of Raleigh Public Utilities Department I NC 540 Impact on Wrenn Road Facility Evaluation ���
Preliminary Project Opinion of Probable Costs
between the Wrenn Road Facility and future replacement site are unknown; the new site could
be immediately adjacent to the existing site or could be as much as five miles away. Property
values for suitable size parcels, for both fee -simple acquisition and temporary or permanent
easements, are also uncertain in this developing area. In addition, the City's ability to acquire
additional land is uncertain, as well as the ability to permit additional off -site irrigation lands.
The level of certainty for the project cost opinion is +50%/-30% within the AACE International
definition of a Class 5 standard for cost opinions at this stage of project definition, meaning that
the range of construction costs could be from $1.8 million to $6.0 million on the low end of the
scale to $4.8 million to $13.8 million on the high end of the scale for a 50-ft setback or 150-ft
setback.
The following assumptions were applied in developing the cost opinion:
• Property acquisition for new irrigation area to replace the area lost due to NC 540 is based
on an irrigation area of 11.4 acres for a 50-ft setback or 150-ft setback. Accounting for
land which is not usable for spray irrigation, the suitable minimum parcel size is estimated
to be 22 acres, depending on the particular site and setback requirements applied. The
estimated cost per acre is based on Wake County property tax database value of
representative parcels exceeding 20 acres in the vicinity of the Wrenn Road Facility site.
However, as noted above, there is significant uncertainty in property costs due to market
conditions and parcels available for sale, and the City's costs could be significantly higher.
For planning purposes, the property acquisition cost is estimated at $30,000 - $60,000 per
acre. A property immediately adjacent to the Wrenn Road Facility site is preferred, though
the City may need to include parcels remote from the site in their search. The range of
per -acre costs would be applicable to either case.
• Easement acquisition for the pipeline between the Wrenn Road Facility and a new remote
irrigation area is based on an easement width of 30 feet centered over the line, with an
irrigation area minimum parcel size of 20 acres. Easement cost is estimated to be
approximately $100,000 per mile of offsite pipeline.
• On -site installed PVC piping costs are based on similar project costs in unpaved
easement, varying by pipe diameter, $20 to $30 per linear foot. Offsite installed piping
costs, including an allowance for fittings, valves, and air release valves, are based on
similar project costs in roadway rights of way, 6-inch ductile iron, $120 per linear ft.
• On -site irrigation system components are based on vendor -provided unit costs with added
installation allowance. Cost for fittings and all installation costs are incorporated into the
$250 per -sprinkler cost.
• A $50,000 allowance is provided for control system programming. In addition, an
allowance of $100,000 to $500,000 is provided for a dedicated control system for the new
irrigated area including cellular or radio communication to support SCADA monitoring and
control; the higher end of the range represents additional costs if the new irrigation site is
not adjacent to the existing Wrenn Road Facility.
12

City of Raleigh Public Utilities Department I NC 540 Impact on Wrenn Road Facility Evaluation ���
Preliminary Project Opinion of Probable Costs
• A new dedicated pump station is assumed to serve an off -site new irrigation area, with an
approximate firm capacity of 550 gpm, due to the complexity of modifying current pump
facilities for significantly different operating requirements.
• Site improvements budgeted for the new irrigation site include security fencing (estimated
at 4,000 linear ft), site lighting, gravel roads and monitoring wells (estimated at 4 wells).
• Design and construction administration costs for the project are included as a multiplier
applied to the construction cost estimates at 15 percent of construction costs. Design
allowance includes routine permitting costs.
• Project contingency of 30% added, reflecting the early stage of project definition
• The cost opinion does not include costs associated from lost opportunity uses for the
impacted areas, such as timber harvesting or utilization of the site for purposes other than
spray irrigation, such as a wastewater pump station.
• This cost opinion does not include the value of the property taken by NCDOT for Right of
way or storm drainage easement
The opinion of probable construction costs is based on price data from recent bid data of similar
projects within the state market, cost data obtained from manufacturers' representatives, and
published data of material and estimating databases.

Please see Condition 1II.9 prohibiting public access to the treatment and disposal site.
Because a new subdivision and high school are being constructed in the immediate vicinity, it is
recommended gated access to the facilities be installed to the Wrenn Road entrance and additional
fencing on the site.
As part of the application, Permittee has requested establishment of background
concentrations for arsenic, iron, and/or manganese above the groundwater standards contained in
Attachment C. The City has obtained monitoring data that suggests that background concentrations of
arsenic, iron and manganese occur at levels greater than the groundwater standards established in 15A
NCAC 02L. Per 15A NCAC 02L .0202(b)(3), the Director shall determine the groundwater standard to
be the natural occurring concentrations. Please coordinate Nvith the Raleigh Regional Office to ensure that
appropriate monitoring data is obtained to support a background concentration determination. Also,
consider the following guidance material in determining background concentrations:
1. Aquifer Protection Section Policy for Metals Determinations Required by Title 15A, North
Carolina Administrative Code, Subchapter 2L (May, 2013)

Until a background concentration can be established, and the permit modified to reflect site -specific
groundwater standard, the Division will use its enforcement discretion on reported monitoring data for
arsenic, iron and manganese. Please note additional footnotes in Attachment C that recognizes this
process.
If any parts, requirements or limitations contained in this permit are unacceptable, the Permittee
has the right to request an adjudicatory hearing upon written request within 30 days following receipt of
this permit. This request shall be in the form of a written petition, conforming to Chapter 150B of the

of pH shall be made after purging and prior to sampling for the remaining parameters. `
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum. -
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 621 OD. PQL at 0.5 µg/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at OS µg/I, or less
e. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported.
W00002708 Version 3.0 Attachment C Page I of 2

5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Raleigh Regional Office Aquifer Protection Supervisor, telephone number
[phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well. additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment.
8. Monitoring data suggest that the naturally occurring background concentrations may exceed the groundwater quality standards for arsenic, iron, and manganese. Per 15A NCAC 02L .0202(b)(3),
the Permittee has applied to the Director to establish background concentrations and site specife water quality standards for these parameters. Final determination of background concentration for
arsenic, iron, and manganese were pending upon issuance of this permit (March XX 2015), The Division shall use enforcement discretion for any apparent ground water standard violation for
arsenic, iron or manganese until background concentrations and site specific groundwater quality standards can be determined.
