SOIL MANAGEMENT PLAN
Proposed Southline Apartments
Brownfields Agreement (BFA) 10036-06-60 dated July 8, 2011 and recorded July
13, 2011, concerns a 22.41-acre assemblage in Charlotte, North Carolina that
Cherokee Southline, LLC proposes to put to mixed commercial, high-density
residential and recreational use, with associated parking and landscaped areas.
Fifteen parcels were assembled for the Brownsfield Agreement; the right-of-way
easement of the City of Charlotte’s light rail line separates, in a north-south
direction, parcels facing Dunavant Street from those facing South Boulevard.
The subject property of the proposed Southline Apartments consists of nine (9)
contiguous taxable parcels of land that are part of the larger land area
designated for redevelopment and subject to the Brownfields Agreement. The
subject property encompasses approximately 11 acres, and is referenced by
Mecklenburg County Parcel Identification Numbers 12104101, 12104103 through
12104108, 12104110, and 12104111. Addresses associated with the subject
property include 140 Remount Road, 2517 Dunavant Street, 2415 Dunavant
Street, 2405 Dunavant Street, 2401 Dunavant Street, 2309 Dunavant Street,
2301/2303 Dunavant Street, 2321 Dunavant Street, and 2235 Hawkins Street.
The subject property currently has no existing structures, with remnants of
demolished building foundations, paved surfaces, and concrete rubble. Portions
of the concrete rubble have been arranged at the parcel perimeters running
along Dunavant Street, apparently to assist in erosion control. All monitoring
wells on the property that could be located, have been abandoned in accordance
with the Brownfields Agreement by Cherokee Southline, LLC.
As described below, certain impacts have been identified within the soil on these
parcels. Therefore, the contractor must adhere to the soil management protocols
outlined herein during redevelopment activities at the subject site.
Project Background
Cherokee Southline, LLC completed eighteen (18) Phase I Environmental Site
Assessments (ESAs) and nine (9) Phase II ESAs on the larger land area
consisting of fifteen (15) parcels of land (including the 9 parcels of the subject
property). During the completion of the Phase II ESAs, soil samples were collected
and analyzed to determine whether the historical commercial use of the properties
had affected the soil at the subject property. Soil samples were collected and
analyzed for volatile organic compounds (VOCs), semi-volatile organic compounds

(SVOCs), and RCRA 8 Metals on various parcels of the subject property. In
addition groundwater samples were also collected and analyzed for VOCs, SVOCs,
and RCRA 8 Metals on various parcels of the subject property. The analytical
results of the soil samples collected on the subject site indicated that two areas on
the site had concentrations of total chromium above the prior Inactive Hazardous
Site Branch (IHSB) Soil Remediation Goal (SRG) for total chromium and one area
had soil with residual petroleum impact. Low levels of solvents were present in
groundwater samples collected from monitoring wells in the northern portion of the
site. It is believed that these solvents are migrating from an off-site source.
Additionally, one 600 gallon heating oil underground storage tank (UST)
remained in place on the 2321 Dunavant Street parcel of the site. In August
2011, as per the Brownfields Agreement, Cherokee removed the heating oil UST.
The UST closure documentation indicated that residual petroleum impacted soil
remained in the area of the UST. Cherokee recently conducted additional soil
excavation in this area and analyzed multiple sidewall samples. This information
was submitted to Department of Natural Resources (DENR) in the Limited Site
Assessment Report dated October 2011. Based on laboratory data, residual
petroleum in excess of the Residual Maximum Soil Contaminant Concentrations
(MSCCs) remain in place after completion of the excavation in this area at depths
below nine (9) feet below ground surface. This UST basin is one of the areas of
Historic Contamination discussed below.
Based on review of the preliminary grading plans provided by JLB Southline,
there are areas below and above finish grade. Cut and fill activities will be utilized
across the subject property to establish finish grade. In addition, approximately
18,000 cubic yards of additional fill will be placed on the site to complete the
grading activities. The areas of cut are proposed to be above the existing
groundwater table so saturated soils should not be disturbed. In addition, once
the site has been brought to grade and construction of the buildings and
installation of underground utilities start, saturated soil is not anticipated to be
encountered. However, in the event saturated soil is encountered during
excavation activities they are to be handled as outlined in this soil management
plan.
As part of a Phase II Environmental Site Assessment dated December 2006, a soil
sample (RR-SB-1) was collected in the vicinity of an abandoned fuel oil UST at 140
Remount Road. RR-SB-1 was collected at .25’ to 2’ below ground surface. DRO
(370 ppm) was detected in RR-SB-1. The abandoned fuel oil UST was removed
from the eastern side of the former building located as documented in the Heating
Oil UST Closure Documentation Report dated May 24, 2008. The excavation area
was 26’ long x 15’ wide x 13’ in total depth. The soils in the vicinity of RR-SB-1 were
removed during excavation around the UST. See Figure 6, Limited Site
Assessment Report dated May 2008 (the “LSA Report”). Three soil samples (S-1

through S-3) were collected at the bottom of the UST basin. One of these samples
contained 12 ppm DRO at 13’ bgs; the remaining samples were below the
actionable level of 10 ppm for TPH. Subsequently, a LSA Report was prepared. No
petroleum constituents were detected in the groundwater sample collected from the
monitoring well installed during the LSA Report above 2L Groundwater Standards.
No petroleum constituents were detected in the soil samples collected as part of the
LSA Report and analyzed using risk-based testing methods. This UST basin is the
one of the areas of Historic Contamination discussed below.
Figure 3 depicts the approximate location where residual petroleum impacted
soil may be encountered during redevelopment activities. Redevelopment
activities are expected to predominantly occur in unsaturated soils above the
water table. A summary of historical soil analytical results are provided in
Attachment A.
Summary of Additional Assessment Since the Brownfields Agreement
In April 2011, PSI completed a Phase I ESA, and conducted a geotechnical
evaluation, a geophysical survey and a ground penetrating radar survey of the
subject property. The geophysical survey and ground penetrating radar survey
determined that there were two subsurface anomalies on the site that could be
possible USTs.
In August 2011, PSI assessed the two subsurface anomalies detected (during
the geophysical/ground penetrating radar survey) at 140 Remount Road and
2415 Dunavant Street. The anomaly located at 140 Remount Road was
determined not to be a UST or any other non-soil material. The anomaly located
at 2415 Dunavant Street was determined to be a concrete slab approximately 4
feet below existing ground surface.
PSI collected two (2) soil samples on the subject property in the areas where
total chromium was detected above the IHSB SRGs. The soil samples were
collected at approximately the same locations and depths of the original soil
samples analyzed (RR-SB-3 and OA-SB-2). The soil samples were analyzed for
total chromium, chromium III, and hexavalent chromium (chromium VI). The
results indicated that the species of chromium detected at the site do not exceed
the IHSB SRGs. Analytical results are provided in Attachment A. This sampling
event is documented in the Soil Sampling Summary Report dated September 29,
2011. Thus, chromium is no longer viewed as a Contaminant of Concern (CoC)
at the subject property.
In October 2011, ERM completed a Limited Site Assessment Report (as
amended and updated by the Limited Site Assessment Addendum) in the vicinity
of the former heating oil UST located at 2321 Dunavant Street.

Pre-Construction Activities
Site development requires the import of approximately 18,000 cubic yards of fill
soil from an off-site borrow area. JLB Realty will request a letter of certification
from the borrow pit, indicating that the off-site fill soil meets the requirements for
clean fill soil as required by the Brownfields Agreement. If the off-site borrow pit
can not provide JLB Southline with a letter of certification satisfactory to DENR,
then the Environmental Representative for JLB Southline will collect soil samples
for laboratory analysis from the borrow pit to verify suitability of the soil. The soil
samples will be analyzed for VOCs by EPA Method 8260B, SVOCs by EPA
Method 8270C, and Priority Pollutant Metals plus manganese by EPA Method
6010C and 7471B. The number of soil samples collected will be based on the
amount of fill soil to be excavated from the borrow pit and as required by DENR.
Proposed Construction
PSI’s understanding of the proposed construction on these parcels are based on
preliminary design drawings which were prepared by The John R. McAdams
Company, Inc., dated July 15, 2011. Specific drawings related to the excavation
and handling of soil are presented in Attachment B. If substantial deviations
from the design drawings occur due to unexpected conditions during
construction, revisions to this soil management plan may be required.
Redevelopment activities are expected to predominantly occur in unsaturated soil
above the water table.
Based on review of the preliminary grading plans provided by JLB Southline,
there are areas below and above finish grade. Cut and fill activities will be utilized
across the subject property to establish finish grade. In addition, approximately
18,000 cubic yards of additional fill will be placed on the site to complete the
grading activities. This soil is to be provided by an off-site borrow pit.
Based on the preliminary site plan and geotechnical assessment conducted on
the subject property, the majority of the proposed structures will have shallow
foundations less than five (5) feet in depth. Several of the proposed structures
will require ground improvement prior to construction. Based on geotechnical
engineering data, stone columns (Geo-piers) will be used for ground
improvement in the area of these structures. These structures are located in the
northeast quadrant of the site. Soil generated during the installation of the stone
column will be reused on-site and/or disposed of off-site in accordance with this
soil management plan.
Based on the preliminary site plan of the subject property, the majority of the
proposed underground utilities will be installed above the groundwater table.
Proposed Southline Apartments
Soil Management Plan
Brownfields Agreement 10036-06-60

Several of the underground utilities may encounter groundwater. Unsaturated soil
generated during the installation of the underground utilities will be reused on-site
and/or disposed of off-site in accordance with this soil management plan.
Saturated soil generated during the installation of the underground utilities will be
stockpiled on-site and handled in accordance with this soil management plan.
Based on the previous environmental assessment conducted at the subject
property, there are two potential areas where the on-site soil has or is reasonably
likely to have residual petroleum impact (the “Historic Contamination”): the
southern corner of the land parcel located at 140 Remount Road at depths of
twelve (12) feet or more beneath the surface of the ground, and a portion of the
former UST basin at 2321 Dunavant Street as more particularly shown on Figure
3 at depths of nine (9) feet or more beneath the surface of the ground. The CoC
in this area are residual petroleum impacts.
Potentially Impacted Soil (as defined below) that is displaced during construction
activities will be subject to the provisions of the soil management plan. Such
potentially impacted soil are in the area of Historical Contamination (referenced
above and shown on Figure 3) and any additional areas that may be
encountered that have substantial visual or olfactory evidence of impact (the
“Potentially Impacted Soil”). Other soil that may be excavated or displaced at the
property will not be subject to this soil management plan, unless scheduled for
off-site re-use.
When construction activities involve the excavation or disturbance of Potentially
Impacted Soil, an Environmental Representative (i.e. environmental personnel
trained in the identification, field screening, and sampling of contaminated
materials), will observe, and monitor using a continuously-reading
Photoionization Detection (PID) and/or Flame-ionization Detector (FID) to
document the condition of the soil during excavation activities, including
identification of potential contamination, and identification of saturated and
unsaturated soil. The PID and/or FID will be calibrated at least daily and/or in
accordance with manufacturer’s specifications and calibration readings will be
recorded in field notes.
Based on field screening and visual and olfactory evidence reviewed by the
Environmental Representative, the Potentially Impacted Soil will be segregated
and stockpiled into Type-1 through Type-5 soils and debris. The Environmental
Representative will collect samples of the soil stockpiles for laboratory analysis to
evaluate their potential for on-site re-use or off-site disposal as discussed below.

On-Site Soil Designations
Soil will be grouped into the following categories during redevelopment activities
at the site:
Type-1 – Soil that is not Potentially Impacted Soil (as defined on page 5).
This soil may be excavated or displaced at the property and will not be
subject to this soil management plan unless scheduled for off-site re-use
or disposal.
In the event of off-site reuse or disposal, Type-1 soil shall be managed in
same way as Type-2 soil.
Type-2 – Potentially Impacted Soil excavated or disturbed above the water table
and deemed to be non-impacted based on visual evidence, olfactory evidence
and field screening readings (< or =10 PPM on a PID and/or FID).
This soil may be reused on-site with no further analytical testing or
restrictions.
In the event of off-site reuse, such soil will be treated as Type-3 soil.
In the event of off-site disposal, Type-2 soil must be handled as required
by applicable laws and regulations. It should be noted, although NCDENR
considers the soil to be clean, the off-site disposal facility may require
analytical testing on the soil.
Type–3 – Potentially Impacted Soil excavated or disturbed above the water
table and deemed impacted based on visual evidence of petroleum impact,
olfactory evidence of petroleum impact and/or elevated field screening readings
(>10 PPM on a PID and/or FID).
If the field screening of Type-3 soil with the PID and/or FID indicates the
soil is equal to or less than 10 PPM, the soil can be used on-site with no
additional analytical testing or restrictions.
If the PID and/or FID screening of Type-3 soil indicates the soil impact is
greater than 10 PPM, the soil will be segregated, stockpiled on-site, and
analyzed for CoC as discussed below. Based on laboratory results, the
soil can be handled in one or more of the following ways:
o If testing of the soil in the Historic Contamination areas yield less than
or equal to 10 ppm TPH using TPH Methods, the soil can be reused on
site with no further analytical testing or restrictions.
o If no CoC exceed the Residential MSCCs established by the UST
Section of the Division of Waste Management of DENR, the soil can be
reused on-site with no further analytical testing or restrictions.
o If one or more of the CoC exceeds the Residential MSCCs, the soil
can be reused on-site under an impervious surface in accordance with
Proposed Southline Apartments
Soil Management Plan
Brownfields Agreement 10036-06-60
November 21, 2011

a plan approved by DENR. Any soil proposed for such reuse shall be
sampled and analyzed by Toxic Characteristic Leaching Procedure
(TCLP), and no soil that fails TCLP analysis shall be reused at the
Brownfields Property.
o If one or more of the CoC exceed the residential MSCCs, the soil may
be disposed of off-site at a disposal facility approved or permitted to
accept impacted soil.
o Soil that is impacted with CoC other than petroleum constituents will be
reclassified as Type-4 soil (discussed below).
The identification of Type-3 soil in areas other than those previously
documented will require notification of the DENR contact listed in the
Brownfields Agreement.
Type-4 – Any saturated soil and/or Potentially Impacted Soil impacted with CoC
in addition to or other than petroleum constituents (including reclassified
construction and organic debris.)
Type-4 soil and debris shall be segregated and stockpiled on the site.
Type-4 soil and debris shall be analyzed in accordance with the
procedures discussed below.
o If no CoC exceed the IHSB Preliminary Health-Based Residential
SRGs or the IHSB Protection of Groundwater SRGs, then the soil shall
be re-classified and may be used or disposed of as Type-1 soil.
o If one or more CoC exceed the IHSB Preliminary Health-Based
Residential SRGs the soil can be reused on-site under an impervious
surface in accordance with a plan approved by DENR or as otherwise
directed by DENR. Any soil proposed for such reuse shall be sampled
and analyzed by Toxic Characteristic Leaching Procedure (TCLP), and
no soil that fails TCLP analysis shall be reused at the Brownfields
Property.
o If one or more CoC exceed the IHSB Protection of Groundwater SRGs
(but not the IHSB Preliminary Health-Based Residential SRGs), the
soil can be reused on-site in accordance with a plan approved by
DENR.
o If one or more CoC exceed the IHSB Preliminary Health-Based
Residential SRGs or IHSB Protection of Groundwater SRGs, the soil
may also be disposed of off-site at a disposal facility approved or
permitted to accept such soil.
The identification of Type-4 soil in areas other than those previously
documented will require notification of the DENR contact listed in the
Brownfields Agreement.

Type-5 – Construction and/or organic debris (bricks, concrete, boulders, steel,
wood).
No visual or olfactory evidence of impact:
o The material can be used on-site as local, state, and/or federal law
permits.
o If material can not be used on site then it can be transported to an
approved off-site disposal facility without further testing. It should be
noted that the disposal facility may require additional testing prior to
accepting the material.
Evidence of impact (visual and/or odor):
o The material shall be reclassified and treated as Type-4 construction
and organic debris.
Soil Stockpiling and Sampling Procedures
The soil stockpiles will be constructed as follows, to mitigate potentially impacted
soil being in contact with non-impacted surface soil:
Soil will be stockpiled on 10-mil plastic sheeting.
The stockpile will be bermed with straw bails and/or soil and the underliner
will cover the berm material.
The stockpile and berm will then be covered with 10-mil thick plastic
sheeting. The plastic cover will be secured.
The top soil should be stripped and stockpiled separately from the underlying
soil.
Once the stockpiles are created, it will be necessary to sample the stockpiles in
order to characterize the concentrations of the chemicals-of-concern in the
material. The stockpiles will be sampled by JLB Southline LLC’s environmental
consultant.
Sampling of Type-3 soil - The stockpiled soil sampling shall be conducted as
outlined in the NCDENR UST Section “Guidelines for Assessment and Corrective
Action for UST Releases” (July 2008 Change 1 December 2008) and “Guidelines
for Sampling” (July 2008 Change 1 December 2008). A copy of the guidance is
provided in Attachment C for reference. Stockpiles shall be sampled as follows:
The number of composite samples to be collected from each stockpile will
depend upon the stockpile volume. The requirement for sampling soil
stockpiles are as follows:
o One composite soil sample will be collected per 200 yards.
Proposed Southline Apartments
Soil Management Plan
Brownfields Agreement 10036-06-60
November 21, 2011

o Each composite soil sample will be comprised of soil samples collected
from two randomly placed soil borings.
o Six (6) primary soil samples will be used to generate each composite
sample. The six (6) primary samples will be collected as follows: Three
(3) soil samples will be collected from within each soil boring. Each of
the three samples collected from the borings will be collected at
different depths.
Soils from the Historic Contamination area (former 12,000 gallon fuel oil
UST basin) at 140 Remount Road and in the former heating oil UST basin
at 2321 Dunavant Street shall be analyzed for TPH GRO/DRO using EPA
Method 8015, including 3550/5030 preparation methods (the “TPH
Methods”). If levels exceed 10 ppm, Soils from the Historic Contamination
area shall be analyzed using the methods in the bullet below.
Unless otherwise approved by DENR, soil samples from other petroleum-
impacted areas shall be analyzed by a North Carolina certified laboratory
for VOCs by EPA Method 8260B, SVOCs by EPA Method 8270C, and
Chromium and Lead by EPA Method 6010C and 7471B.
Sampling for Type-4 soil and Type-5 debris (with evidence of impact) - the
stockpiled soil and debris sampling shall be conducted as outlined in the soil
management plan and in the NCDENR IHSB “Guidelines for Assessment and
Cleanup” (August 2011). A copy of the guidance is provided in Attachment C for
reference. Stockpiles shall be sampled as follows:
Soil stockpiles shall be sampled separately.
The number of composite samples to be collected from each stockpile will
depend upon the stockpile volume. The requirement for sampling soil
stockpiles are as follows:
o Stockpiles should be divided into equal segments of approximately
100 cubic yards (c.y.) each.
o Three (3) boring locations per segment (use random or biased
selection).
o Soil samples will be collected from two depths within each boring
(minimum six (6) samples per segment).
o Composite samples will be collected only within each segment. For
samples submitted for volatile analysis, at least 25-percent will be
collected as unmixed grab samples.
o For areas of residual impact, PSI will use visible or field-screening
evidence to collect additional biased samples.
Proposed Southline Apartments
Soil Management Plan
Brownfields Agreement 10036-06-60
November 21, 2011

Unless otherwise approved by DENR, soil samples shall be analyzed by a
North Carolina certified laboratory for VOCs by EPA Method 8260B,
SVOCs by EPA Method 8270C, Priority Pollutant Metals plus manganese
by EPA Method 6010C and 7471B, and hexavalent chromium by EPA
Method 7196A, and TCLP Metals.
Laboratory results should be compared to the NCDENR IHSB Preliminary
Health-Based SRGs and Protection of Groundwater SRGs. The appropriate
screening criteria are provided in Attachment D.
Potential Soil Handling Health and Safety Concerns
While specific health and safety requirements are necessary for the handling and
long-term placement of soil that will be generated during construction activities
on the Southline property, the potential health effects for construction workers in
handling the soil are considered to be very low. Residual petroleum impacts exist
in several areas of the property. Chromium is no longer considered a concern
since, subsequent soil testing has indicated the individual species of chromium
do not exceed their respective IHSB SRGs. These Soil Cleanup Target Levels
are based on long-term exposure; however, the exposure to construction workers
is likely to be short term (less than 1 year). Therefore, the potential health risk to
construction workers is expected to be very low. JLB Southline shall comply with
all OSHA rules applicable to the site in performing activities in connection with
this soil management plan.
Post Construction Soil Sampling
Following final grading activities, composite soil samples will be collected in the
proposed green space areas of the site where residual soil is present at the
surface. Each of these areas shall be known as a “Green Space Area.”
Composite soil samples shall not be required in parts of the site where fill has
been placed over the surface of the presently existing grade. These samples will
be collected prior to installation of building footings and the curb and gutter
system. The upper 2 feet of soil in each Green Space Area will be considered a
composite sample area. Each of the composite samples will be comprised of soil
collected from three (3) to six (6) aliquots. The number of aliquots collected will
be dependant on the size of each Green Space Area requiring sampling and as
outlined in the NCDENR IHSB “Guidelines for Assessment and Cleanup” (August
2010).
Each of the composite soil samples will be analyzed for VOCs by EPA Method
8260B, SVOCs by EPA Method 8270C, Priority Pollutant Metals plus manganese
by EPA method 6010C and 7471B, hexavalent chromium by EPA Method
7196A, and TCLP Metals. In addition to analyzing the composite samples each

of the aliquot samples will be submitted to the laboratory and placed on hold for
potential future analysis. The aliquots will only be analyzed if the analysis of the
composite soil samples indicates CoC above IHSB soil remediation goals.
A final report summarizing the post-construction sampling of the Green Space
Areas shall be submitted to the DENR contact listed in the Brownfields
Agreement. If soil in any of the Green Space Areas exceeds IHSB Preliminary
Health-Based Residential SRGs, such impacted soil must be removed if located
within 2-feet of the ground surface and replaced with clean fill. Clean fill shall be
established pursuant to the procedures discussed in the section entitled “Pre-
Construction Activities” above. Any soil in a Green Space Area or removed from
a Green Space Area which exceed IHSB Preliminary Health-Based Residential
SRGs shall be managed in accordance with a plan pre-approved by DENR in
writing.

Inactive Hazardous Sites Program
Guidelines for
Assessment and Cleanup
August 2011
Department of Environment and Natural Resources
Division of Waste Management
Superfund Section
Inactive Hazardous Sites Branch
401 Oberlin Road - Suite 150
(Note: our physical address in October 2011 will be 217 West Jones Street)

Raleigh, North Carolina 27699-1646
Telephone: (919) 508-8400
http://portal.ncdenr.org/web/wm/sf/ihshome
i
Purpose and Intended Use of the Guidelines
These guidelines outline the minimum technical and administrative procedures for all site
assessments and site cleanups conducted pursuant to the Inactive Hazardous Sites Response Act
of 1987 (N.C.G.S. 130A-310 et.seq.). The guidelines do not apply to cleanups conducted under
the Inactive Hazardous Sites Branch’s Registered Environmental Consultant (REC) Program.
For additional information on the REC Program, please refer to the most recent edition of the
REC Program Implementation Guidance.
These guidelines should be used by remediating parties at priority action sites when responding
to Site Assessment Request Letters, Site Assessment Orders, Site Cleanup Request Letters,
Remedial Action Orders and Administrative Agreements for voluntary remedial actions not
conducted under the REC program. Due to the wide range of conditions encountered at
hazardous substance disposal sites, the guidelines will not address every conceivable situation.
At most sites, the consultant will need to prescribe additional sample collection and analyses
based on site-specific conditions. The importance of retaining a qualified and experienced
environmental consultant cannot be overemphasized.
Note: In order to be acknowledged and receive Inactive Hazardous Sites Branch approval,
all voluntary site cleanups, whether managed under the REC Program or managed
directly by the Inactive Hazardous Sites Branch, must be conducted pursuant to an
Administrative Agreement with the Division of Waste Management.
ii
Submittal of Documents
All work plans and reports should be submitted in both paper and electronic formats unless
otherwise instructed by branch staff. Specifications for electronic document submittal can be
found at: http://portal.ncdenr.org/web/wm/sf/ihshome.

1.0 Introduction
1.1 Statutory Authority
The Inactive Hazardous Sites Program was created by the Inactive Hazardous Sites
Response Act of 1987 (N.C.G.S. 130A-310 et. seq.). Authority for implementing the
statute has been delegated to the Director of the Division of Waste Management
(division).
The Inactive Hazardous Sites Program is a state program that derives its authority from
the state statute referenced above.Compliance with these guidelines does not ensure
compliance with the National Contingency Plan or CERCLA/SARA.
1.2 Jurisdiction
The program addresses releases to the environment of hazardous substances, as defined
in CERCLA/SARA. The program addresses both pre-1980 and post-1980
disposal/releases. Except as noted below, the program's jurisdiction is not limited by
facility type or operating status.
The program does not address RCRA permitted or interim status facilities, or any sites
where the Environmental Management Commission, the Commissioner of Agriculture, or
the Pesticide Board have assumed jurisdiction.
N.C.G.S. 130A-310.9 provides site owners, operators, or responsible parties an
opportunity to voluntarily clean up inactive hazardous substance or waste disposal sites
with the approval of the division. This voluntary remedial action program is
administered by the division's Inactive Hazardous Sites Branch (branch).
1.3 Categories of Site Cleanups
1.3.1 Voluntary remedial actions
Amendments to the Inactive Hazardous Sites Response Act in 1994 and 1995
provided the division with the authority to approve qualified environmental
consultants to certify that remedial actions are in compliance with state law. At
eligible voluntary remedial action sites, the remediating party may now retain an
approved environmental consultant to both perform and certify a remedial action
in lieu of state oversight. These changes were instituted because of the limited
state staff resources available to oversee voluntary remedial actions. The division
continues to have complete discretion to directly oversee any voluntary remedial
action, however, due to resource limitations, all eligible sites will be directed into
the privatized oversight program known as the Registered Environmental
Consultant (REC) Program. Remediating parties wishing to conduct a voluntary
remedial action must first notify the branch, in writing, of their desire to conduct a
voluntary remedial action. Upon receipt of such notice, the branch will request
that the remediating party complete a Site Cleanup Questionnaire with the aid of
their environmental consultant. The questionnaire will be used to expedite the
site eligibility screening process. Sites having any of the conditions listed on the
questionnaire are not automatically ineligible for the REC Program, but will be
2
reviewed in more depth prior to assigning the site to either the REC or state-
supervised voluntary remedial action programs. The Site Cleanup Questionnaire
can be found at: http://portal.ncdenr.org/web/wm/sf/sfavailabledocs.
1.3.1.1 Remedial actions under REC program
The remediating party is required to hire a division approved REC to
perform and certify all remedial activities at the site. Prior to initiating
any site work, the remediating party is also required to sign a limited
Administrative Agreement (Agreement) that outlines the requirements
for the remedial action.
Upon remedial action completion and final certification by the REC,
the site will be assigned “No Further Action” status in the Inactive
Hazardous Sites inventory. This change of inventory status does not
preclude any future state action if new evidence of contamination is
discovered at a later date.
Note:Site cleanups under the REC Program do not receive state
oversight. The branch will, however, perform random and
targeted audits of sites in the REC Program. For additional
information, please refer to most recent edition of the REC
Program Rules and Implementation Guidance.
1.3.1.2 Remedial actions under branch oversight
The branch will oversee voluntary site cleanups, at sites not eligible
for the REC Program, pursuant to Administrative Agreements with the
remediating party. Under this category of voluntary remedial actions,
the branch provides review and concurrence for project work,
including remedial investigation work plans, remedial investigation
reports, remedial action plans and remedial action reports. The
remediating party does not have to hire a Registered Environmental
Consultant to perform this work.
1.3.2 Priority actions
When the branch determines a site is a priority for action, it will solicit the
cooperation of the responsible party to perform assessment or cleanup activities
by issuing a Remedial Investigation Request Letter or Site Cleanup Request
Letter. The branch will review documents and oversee work related to
compliance with Remedial Investigation Requests without an Agreement.
However, to comply with Site Cleanup Requests, responsible parties must sign an
Agreement before they begin any site work. Based on site conditions, the branch
will determine if the remedial action will be supervised by the state or an REC. If
the responsible party does not comply with the solicitation letters, the branch may
issue an Order compelling action.
3
1.4 No Further Action Letters
After satisfactorily completing a voluntary remedial action (either REC or state
oversight), the remediating party will receive a letter indicating that the work required
under the Agreement has been completed and the Agreement is terminated. The site will
then be assigned "No Further Action" status in the Inactive Hazardous Sites inventory.
This change of inventory status does not preclude any future state action if new evidence
of contamination is discovered at a later date.
In accordance with N.C.G.S. 130A-310.7(c), any party wishing to receive a "No Further
Action" letter must provide the request in writing. The party requesting the letter may
also be required to reimburse the state for expenses incurred while reviewing the no
further action request. This requirement applies to all voluntary remedial action sites
under the Inactive Hazardous Sites program. Additional information can be found at:
http://portal.ncdenr.org/web/wm/sf/ihs/ra/nfa.
1.5 General Provisions
1.5.1 These guidelines outline the remedial action technical procedures and are not a
substitute for the Inactive Hazardous Sites Response Act, N.C.G.S. 130A-310 et
seq., and any relevant program rules.
1.5.2 This document and the remediation goal tables will be updated as necessary on
the Superfund Section’s Web site. Updates can be found at:
http://portal.ncdenr.org/web/wm/sf/sfavailabledocs.
1.5.3 The branch’s State Directed Cleanup Program is divided into Eastern and Western
regions. A regional map and contact information for all branch programs and
staff and can be found at: http://portal.ncdenr.org/web/wm/sf/ihs/ihsregmap.
1.5.4 N.C.G.S. 130A-310.9(a) requires that in order to participate in the voluntary
cleanup program, the remediating party must pay a fee of $1,000.00. This fee will
be used to help defray the costs of monitoring and enforcing the remedial action
program. This fee must be paid to the Division of Waste Management before an
Administrative Agreement will be executed.
4
2.0 Remedial Investigation Work Plans
The remediating party must submit Remedial Investigation Work Plans to the branch pursuant to
the terms of the Agreement, the Remedial Investigation Request Letter or the Remedial
Investigation Order. The remediating party should not implement the Remedial Investigation
Work Plan before it is approved by the branch.
2.1 Introduction
The Remedial Investigation should be conducted in at least two phases. The Phase I
investigation should identify all releases of hazardous substances to the environment,
characterize the chemical nature of such releases, and collect sufficient sampling data in
order to compile a list of contaminants of concern. Subsequent phases of the
investigation should delineate the lateral and vertical extent of contamination in each area
of concern, to concentrations less than or equal to the remediation goals established
pursuant to section 4.0 of this document. Separate work plans are required for each phase
of the investigation.
The field procedures outlined in the Remedial Investigation Work Plans, specifically
those relating to sample collection techniques, sample containers, sample preservation,
equipment decontamination and field measurement procedures, should comply with the
most current version of the U. S. Environmental Protection Agency (U.S. EPA) Region
IV Science And Ecosystem Support Division (SESD) Field Branches Quality System and
Technical Procedures. This information is available from the USEPA Region IV SESD
at:http://www.epa.gov/region4/sesd/fbqstp/.
Appendix A of this document provides an outline of the minimum sampling and
analytical procedures for the remedial investigation.
2.2 Phase I Remedial Investigation: Identification of Contaminants and
Areas of Concern
The Phase I Work Plan should contain the information described below and be presented
in the order described here.
Site Description
1. Site location information including site street address, longitude and latitude, and
identification of owners and use of the site and all surrounding property.
2. A summary of all management practices employed at the site for hazardous
wastes and any wastes that may have contained hazardous substances, including a
list of types and amounts of waste generated, treatment and storage methods, and
ultimate disposition of wastes. Also include a description of the facility's past and
current RCRA status; the location and condition of any vessels currently or
previously used to store any chemical products, hazardous substances or
hazardous wastes; and a summary of the nature of all on-site contaminant
releases, including one-time disposals or spills.
5
3. United States Geological Survey topographic maps sufficient to display
topography within a one-mile radius of the site.
4. A site map including scale; north arrow; and locations of property boundaries,
buildings, structures, all perennial and non-perennial surface water features,
drainage ditches, dense vegetation, known and suspected spill or disposal areas,
sumps, septic systems, storm water drains and piping, underground utilities,
storage vessels, and existing on-site wells;
5.a. An evaluation of all properties that make up the site and all adjacent property for
the existence of any of the environmentally sensitive areas listed below.
Appendix C provides the telephone contacts that should be made in order to
identify these areas. The information received through these contacts should be
outlined in this section of the work plan. In most cases, none of these areas will
be present. Knowledge of the presence of these sensitive environments is
necessary to determine if any special sampling (such as aquatic toxicity testing) is
required and whether site remediation may do more harm than good (for example,
excavation and destruction of a wetland versus leaving in place residual
contamination which will not significantly impact the wetland environment).

15. A description of equipment and personnel decontamination procedures.
Schedule
16. A proposed schedule for site activities and reporting.
Other Information
17. Any other information required by the branch or considered relevant by the
remediating party.
Certification
18. A signed and notarized certification by a representative of the remediating party
stating, “I certify that, to the best of my knowledge, after thorough investigation,
the information contained in or accompanying this certification is true, accurate,
and complete.”
19. A signed and notarized certification by the consultant responsible for the day to
day remedial activities stating, “I certify that, to the best of my knowledge, after
thorough investigation, the information contained in or accompanying this
certification is true, accurate, and complete.”
20. Any work that would constitute the “practice of engineering” as defined by G.S.
89C shall be performed under the responsible charge of, and signed and sealed by,
a professional engineer registered in the state of North Carolina. Any work that
would constitute the “public practice of geology” as defined by G.S. 89E shall be
performed under the responsible charge of, and signed and sealed by, a geologist
licensed in the state of North Carolina.
Note 1: Items 4, 6, 7 and 8 above may not be required for sites where the area of
concern is limited to a small area of soil contamination only.
Note 2: The remediating party is responsible for developing appropriate health and
safety measures that conform to all applicable federal and state
regulations. The goal is to ensure that the health and safety of all persons
on and off-site will not be adversely affected by any remedial activity.
2.3 Phase II Remedial Investigation: Delineation of Extent of Contamination
Upon completion of the Phase I remedial investigation, the branch will compile a list of
contaminants of concern for the site.
The remediating party should use the remediation goals referenced in section 4.0 of this
document or site-specific natural background levels for metals, if less stringent, in order
to delineate the extent of contamination. The branch will determine remediation goals
for any contaminants not listed in the tables.
8
The Phase II (and any necessary subsequent phases) Remedial Investigation Work Plan
should include items 10-20 above, presented in that order.
Note: Any sites having volatile organic compounds will be required to assess
structural vapor intrusion potential. For additional information, contact the
branch.
9
3.0 Remedial Investigation Reports
After each phase of the remedial investigation, the remediating party should prepare a Remedial
Investigation Report that includes the minimum information listed below. These reports must be
submitted to the branch pursuant to the terms of the Agreement, the Remedial Investigation
Request Letter or the Remedial Investigation Order.
Remedial investigation reports should be organized in sections corresponding to the following.
At minimum, they should include the following elements.
Methods of Investigation
1. A narrative description of how the investigation was conducted, including a discussion of
any variances from the approved work plan.
2. A description of groundwater monitoring well design and installation procedures,
including drilling methods used, completed drilling logs, "as built" drawings of all
monitoring wells, well construction techniques and materials, geologic logs, and copies
of all well installation permits.
3. A map, drawn to scale that shows all locations where soil, surface water and sediment
were sampled. Also, include all monitoring well locations on the map. In all cases show
each location’s relation to known disposal areas or other sources of contamination.
Monitoring wells should be surveyed to a known benchmark. Soil sample locations
should be surveyed to a known benchmark or flagged with a secure marker until after the
remedial action is completed. A professional land surveyor must conduct all surveying.
4. A description of all laboratory quality control and quality assurance procedures followed
during the remedial investigation.
5. A description of procedures used to manage drill cuttings, purge water and
decontamination water.
Site Geology and Hydrogeology
6. A summary of site geologic conditions, including a description of soils and vadose zone
characteristics.
7. A description of site hydrogeologic conditions (if groundwater assessment is determined
to be necessary), that includes current uses of groundwater, notable aquifer
characteristics, a water table elevation contour map with groundwater flow patterns
depicted, tabulated groundwater elevation data, and a description of procedures for
measuring water levels.
Investigation Results
8. Tabulation of analytical results for all sampling (include sampling dates and soil
sampling depths) and copies of all laboratory reports (see data reporting procedures
shown in section A.8).
10
9. Soil, groundwater, surface water and sediment contaminant delineation maps and cross
sections. Include scale and sampling points with contaminant concentrations.
10. A description of procedures and the results of any special assessments, such as
geophysical surveys, immunoassay testing (U.S. EPA SW-846 4000 series methods), soil
gas surveys, or test pit excavations.
Notes/Photographs
11. Copies of all field logs and notes, and color copies of site photographs.
Other Information
12. If groundwater contamination exists at the Site, an inventory and map of all wells,
springs, and surface water intakes used as sources of water within a one-half mile radius
of the center of the site. If the site is greater than one hundred (100) acres in size, the
inventory and map should cover a one-mile radius from the center of each source area.
13. Any other information required by the branch or considered relevant by the remediating
party.
Certification
14. A signed and notarized certification by a representative of the remediating party stating,
“I certify that, to the best of my knowledge, after thorough investigation, the information
contained in or accompanying this certification is true, accurate, and complete.”
15. A signed and notarized certification by the consultant responsible for the day to day
remedial activities stating, “I certify that, to the best of my knowledge, after thorough
investigation, the information contained in or accompanying this certification is true,
accurate, and complete.”
16. Any work that would constitute the “practice of engineering” as defined by G.S. 89C
shall be performed under the responsible charge of, and signed and sealed by, a
professional engineer registered in the state of North Carolina. Any work that would
constitute the “public practice of geology” as defined by G.S. 89E shall be performed
under the responsible charge of, and signed and sealed by, a geologist licensed in the
state of North Carolina.
11
4.0 Remediation Goals
The branch’s policy for establishing remediation goals is consistent with the intent of
CERCLA/SARA and the National Contingency Plan (NCP), as required by N.C.G.S. 130A-
310.3. The remediation goal tables referenced in this section are periodically updated based on
new or revised toxicological data. Remediation goals for soil and vapor intrusion screening
levels are typically updated twice per year (during the first and third quarters). Therefore,
remediating parties and their environmental consultants should periodically check the
remediation goal tables for updates to ensure that the most current information is being used.
4.1 Remediation Goals for Unrestricted Land Use
This section describes the procedures used to establish remediation goals for unrestricted
land use for each environmental media. Remediation goals for restricted land use are
described in section 4.2.
4.1.1 Remediation goals for soils
The branch has two soil remediation goals: a “health-based” remediation goal for
total concentrations of contaminants (section 4.1.1.1), and a “protection of
groundwater” remediation goal for leachable concentrations of contaminants
(section 4.1.1.2). The remedial action must attain both soil remediation goals.
Note: If sensitive environments are present at a site, the branch may require the
adjustment of remediation goals and/or the proposed remedial alternative.
Decisions will be made based on site-specific conditions.
When developing a Remedial Action Plan (RAP) as discussed in section 5.0, the
remediating party shall attempt to design a remedial action alternative that will
attain the goals described in sections 4.1.1.1 and 4.1.1.2. However, the branch
may adjust remediation goals at the time of remedy selection if warranted. If the
preferred remedy (selection governed by the feasibility study included in the
RAP) cannot achieve the remediation goals provided, the branch will re-establish
levels based on the lowest concentration that can be achieved at the site given that
those levels correspond to less than the maximum cumulative excess cancer risk
of 1 x 10-4 and a hazard index of 1.
4.1.1.1 Health-based soil remediation goals for unrestricted land use
Preliminary health-based remediation goals are shown in the Inactive
Hazardous Sites Branch Soil Remediation Goals Table (SRG Table)
located at: http://portal.ncdenr.org/web/wm/sf/sfavailabledocs . These
remediation goals have been established using current U.S. EPA risk
assessment guidance and are based on a lifetime excess cancer risk of
1 x 10-6 (carcinogens) and a hazard quotient of 0.2 (non-carcinogens).
The hazard quotient of 0.2 is used to account for multiple (average of
five) non-carcinogens in the same critical effect group. These
numbers can be used as final health-based remediation goals. The
branch can adjust these remediation goals at sites with less than five
non-carcinogens in the same critical effect group and for the specific
12
set of carcinogens present. Adjustments can also be made for
restricted uses as described in Section 4.2. The branch must be
contacted for contaminants not listed in SRG Table.
Note 1: The soil remediation goal for PCBs was established in accordance with
U.S. EPA policy for the cleanup of PCBs at Superfund sites. The
unrestricted use remediation goal for PCBs is 1 ppm. This number
may not be adjusted. However, higher levels can remain in subsurface
soils if (1) restrictive covenants, which prevent exposure, are applied
and (2) the remaining concentrations of PCBs in soil are shown not to
pose a threat to groundwater (i.e. soils meet protection of groundwater
remediation criteria). Application of restrictive covenants requires
branch approval (see section 4.2).
Note 2: Some of the remediation goals shown in the SRG Table may be more
stringent than natural background concentrations or practical
quantitation limits. Cleanup to below site-specific natural background
concentrations (metals only) or practical quantitation limits (using the
analytical methods specified in section A.7.1.2) is not required.
Note 3: If the site is currently or likely to become agricultural (crops,
livestock, etc.), remediation goals will also need to be calculated for
this scenario due to the concern for possible uptake of contaminants by
plants and livestock.
Note 4: At sites with surface water contamination, remediating parties may
need to plan the remedial action to address continuing source areas
first. For example, surface water contamination may result from
continuing releases from soils. In this case, soil must be remediated to
levels that will ensure attainment of surface water remediation goals.
Note 5: If soil contamination is causing or will cause a structural vapor
intrusion risk, cleanup levels may be adjusted accordingly.
Note 6: In certain situations, health-based soil remediation goals may be
attained through averaging contaminant concentrations. See Appendix
E for additional information.
4.1.1.2 Protection of groundwater soil remediation goals
Procedure
In addition to meeting health-based remediation goals, soils must also
meet a protection of groundwater soil remediation goal. Soils that
leach organic contaminants in excess of the groundwater remediation
goals will require further remediation. Soils that leach metals in excess
of the groundwater remediation goals (or natural leachable background
concentrations, whichever are less stringent) will also require further
remediation. The protection of groundwater soil remediation goals can
be determined using one of the following methods. The environmental
consultant should evaluate which method is most appropriate for each
13
site.
(1) Use the protection of groundwater values listed on the Inactive
Hazardous Sites Branch SRG Table located at:
http://portal.ncdenr.org/web/wm/sf/sfavailabledocs.
(2) Compare site specific leachability data to the groundwater
remediation goals. Soils that leach contaminants at concentrations
exceeding the groundwater remediation goals require additional
remediation. The branch recommends the use of TCLP or SPLP
analyses to determine the leachability of contaminants. If another
laboratory model is used, the remediating party must demonstrate its
scientific validity and that its precision and accuracy are
commensurate with its stated use.
(3) Use simple scientifically valid mathematical equations, employing
site-specific field data for all parameters, to calculate protection of
groundwater soil remediation goals. For example, companion samples
can be collected from different areas of the site having the
contaminant(s) in question and analyzed for: (i.) the total concentration
of the contaminant(s), and (ii.) the TCLP concentration of the
contaminant(s). The results could be used to determine a total
concentration target level that will ensure the protection of
groundwater criteria is met.
Exceptions
At sites that meet any of the following three conditions, the protection
of groundwater soil remediation goals do not apply:
1. Residual soil contaminant concentrations (total concentrations in
mg/kg) for metals only, do not exceed the site-specific natural
background concentrations;
2. Residual soil contaminant concentrations (total concentrations in
mg/kg) for both metals and organics, do not exceed values of
twenty times the corresponding groundwater remediation goals (in
mg/l);
3. Residual soil contaminant concentrations (total concentrations in
mg/kg) for metals and organics do not exceed the health-based soil
remediation goals for unrestricted land use (in mg/kg) described in
section 4.1.1.1, and either (a) or (b) applies:
(a) The remediating party has determined that all on-site disposal
and releases of hazardous substances occurred over 15 years
ago and sampling demonstrates that the concentrations of the
constituents of concern and any daughter products in
groundwater are below the groundwater remediation goals (see
Section 4.1.2);
14
(b) The branch-approved RAP for the site includes active
groundwater remediation and, based on site conditions and soil
contaminant concentrations, the remediating party can
demonstrate that: (1) soil contaminant concentrations will
passively (or by actions of the groundwater remedy) reduce to
meet the protection of groundwater remedial goals within five
years of initiation of groundwater remediation; (2) soil
contaminant concentrations will not cause an increase in
groundwater contaminant concentrations; and (3) the material
leaching will be captured or treated by the groundwater
remedial system during that period. If active groundwater
remediation is discontinued, the remediating party must
demonstrate that contaminants will no longer leach from soil to
groundwater at concentrations exceeding applicable remedial
goals.
Note: Monitored Natural Attenuation is not considered to be an
active groundwater remedy.
4.1.2 Remediation goals for groundwater
For groundwater contaminants with 15A NCAC 2L standards, remediation goals
are the permanent and interim groundwater standards established under 15A
NCAC 2L. For contaminants without 15A NCAC 2L standards, the remediating
party should contact the Branch.
Note 1: Remediation below the practical quantitation limits (using the
analytical methods specified in section A.7.1.2) or site specific natural
background levels (for metals only) is not required.
Note 2: The permanent and interim groundwater standards are listed in the
North Carolina Administrative Code (NCAC) at 15A NCAC 2L .0202
Groundwater Quality Standards. The NCAC can be found at:
http://portal.ncdenr.org/web/wm/sf/sfavailabledocs.
4.1.3 Remediation goals for sediments
Preliminary remediation goals for sediment are based on the most stringent of:
1. The health-based soil remediation goals listed in the SRG Table (or the
upstream “background” concentrations, if less stringent);
2. Remediation goals sufficient to ensure that contaminated sediment will not
cause exceedances of the remediation goals for groundwater and surface
water; or
3. Remediation goals sufficient to ensure the protection of aquatic receptors.
Maximum sediment contaminant concentrations will be compared to U.S.
EPA Region IV Ecological Risk Sediment Screening Values (sediment
15
screening values). The sediment screening values can be found at:
http://www.epa.gov/region4/waste/ots/ecolbul.html#ecointro.
The branch will determine final remediation goals based on numbers of
carcinogens and non-carcinogens present, ecological risks present, background
concentrations, and levels that cause other media to exceed cleanup targets.
Note 1: To demonstrate compliance with the branch’s preliminary sediment
remediation goals for the protection of aquatic receptors, the
laboratory must achieve sample quantitation limits less than or equal
to the sediment screening values. If this is not possible, the
laboratory must state in the case narrative that the quantitation limits
are the lowest that can be achieved using U.S. EPA-approved
methods.
Note 2: If sediment screening values are exceeded, the remediating party must
provide the following additional information:
1. A table with all sample analytical data.
2. A map drawn to scale with locations of all sampling points.
3. A table containing maximum contaminant concentrations,
upstream contaminant concentrations, U.S. EPA sediment
screening values (please identify sample numbers that have
exceedances) and sample quantitation limits.
4. A statement that indicates whether the contaminated surface water
body is perennial or intermittent.
5. A discussion of the potential mobility of contaminated sediment
and the potential for contaminants to leach into surface water.
6. The names and classifications of all downstream surface water
bodies if they are potential recipients of contaminated surface
water or sediment.
7. The identity of adjacent or downstream wetlands that could be
affected.
8. An estimate of the width and depth of the contaminated surface
water body.
Note 3: If contaminated sediments are located in a wetland or other sensitive
environment, the branch will weigh the benefit of active remediation
with the need for protecting and preserving sensitive environments and
instead using passive remedies or institutional controls.
Note 4: At sites with surface water contamination, remediating parties may
need to plan the remedial action to address continuing source areas
first. For example, surface water contamination may result from
continuing releases from sediment. In this case, sediment must be
remediated to whatever levels will ensure attainment of the surface
water remediation goals.
16
4.1.4 Remediation goals for surface water
Preliminary remediation goals for surface water are established by the Division of
Water Quality (DWQ) using State or Federal surface water standards for the
protection of human health and/or aquatic life. Final remediation goals will be set
at the DWQ standards or upstream “background” concentrations, whichever are
less stringent, with the exception of the following two conditions: (1) if surface
water contamination is causing sediments to exceed cleanup criteria, remediation
of surface water will be necessary to eliminate this effect; (2) if remediation of
surface water is determined to cause unreasonable harm to a wetland (or other
protected environment) alternate goals will be determined by the branch.
4.2 Remediation Goals for Restricted Land Use
Under certain site conditions, it may not be appropriate or feasible to meet the soil or
sediment remediation goals described in sections 4.1.1 and 4.1.3. The remediating party
may propose (for branch review and approval) alternate health-based remediation goals
for soil or sediment based on a restricted land-use exposure scenario. In any case,
remediation goals for protection of groundwater (Section 4.1.1.2) must be met. For
sediment (and sometimes soil), ecological concerns can also alter remediation goals
higher or lower. The process and requirements for proposing restricted land use as a
remedy are described in detail in Appendix D of this document.
In June 2011 House Bill 45 was signed into law allowing risked based remediation at
industrial sites that meet certain criteria. Please see NCGS 130A-310.65 - .77 for
additional information. If a site qualifies for risked based remediation, contact the
branch.
4.3 Structural Vapor Intrusion Potential Evaluation
Any sites having volatile organic compounds will be required to assess structural vapor
intrusion potential. For additional information, see the branch’s vapor intrusion guidance
at:http://portal.ncdenr.org/web/wm/sf/sfavailabledocs.
4.4 Additional Provisions
The branch considers “monitored natural attenuation” to be a potential remedial
alternative for attaining the remediation goals. It is not a waiver of the remediation goals.
If natural attenuation of any contaminated medium is proposed, the remediating party
must demonstrate that it is supported by the results of the feasibility study and that it is
the preferred remedy.
All proposed remedies must include removal and/or treatment of source areas with
contamination exceeding health-based and protection of groundwater remedial goals.
Source areas include waste materials, free product, suspected non-aqueous phase liquids
in porous media, etc.
If a remediating party determines that cleanup to established final remedial goals is not
technically practicable from an engineering perspective, they may submit such a
demonstration to the branch for consideration.
17
5.0 Remedial Action
Once the branch has approved the remedial investigation in writing, the remediating party must
prepare a RAP that includes the minimum information listed below. The RAP must be submitted
to the branch pursuant to the terms of the Agreement, the Site Cleanup Request Letter, or the
Remedial Action Order.
5.1 Introduction
Depending on site conditions and in order to avoid submitting a final RAP that will not
be approvable, it may be advantageous for the remediating party to submit several drafts
of the RAP (e.g. 30%, 90% and final). This would allow the remediating party to receive
contingent approval on proposed alternative(s) prior to the development of final RAP.
The submission of a draft RAP is not required but is encouraged at sites using new
remedial technologies or where treatability studies and/or pilot tests are necessary.
After the branch reviews the RAP and any required amendments have been made, the
revised RAP will be made available for public comment. At this time, the Branch may
request that the remediating party provide additional copies of the RAP for distribution to
the local health director, register of deeds office, and each public library in the county
where the site is located.
The branch will mail notice of the development of the RAP to those parties who have
requested such notice (N.C.G.S. 130A-310.9(b)). The RAP will be available for public
comment in this manner for 30 days after such mailing. If the division director
determines that there is significant public interest in a site, the branch may hold a public
meeting or public hearing. The branch will evaluate and consider all public comments
before approving the RAP.RAPs should not be implemented until written approval is
received from the branch.
The branch will approve or disapprove the RAP within a reasonable period of time of
receipt, but in a period not less than 30 days (public comment period).
Any modifications to the approved final RAP (including scheduling) must be submitted
in writing to the branch for approval.
5.2 Remedial Action Plan
The RAP should be organized in sections corresponding to the following. At minimum,
it should include the following elements.
5.2.1 Objectives
1. A discussion of the results of the remedial investigation. The discussion
should include the media contaminated, contaminants of concern, and the
lateral and vertical extent of contamination.
2. A brief statement of objectives for the remedial action.
18
5.2.2 Evaluation of remedies
1. Technology screening: Identification and listing of potentially applicable
technologies.
2. Feasibility Study: An evaluation of remedial alternatives using the
following feasibility study criteria:
a. Protection of human health and the environment, including the
attainment of remediation goals.
b. Compliance with applicable federal, state and local regulations.
c. Long-term effectiveness and permanence.
d. Reduction of toxicity, mobility and volume.
e. Short-term effectiveness: effectiveness at minimizing the impact of
the site remediation on the environment and the local community.
f. Implementability: technical and logistical feasibility, including an
estimate of time required for completion.
g. Cost.
h. Community acceptance.
5.2.3 Proposed remedy
1. A demonstration that the proposed remedy is supported by the results of
the feasibility study.
2. A detailed description of the proposed remedy, including (where
applicable): process flow diagrams of all major components of the
treatment train; conceptual engineering design reports, plans and
specifications; and a project schedule.
3. A description of all activities that are necessary to ensure that the proposed
method(s) of remedial action is (are) implemented in compliance with
applicable laws and regulations, and that the remediation goals established
hereunder are met. These activities include, but are not limited to, well
installation and abandonment, sampling, run-on/run-off control, discharge
of treated waste streams, and management of remediation-derived wastes.
4. The results of any treatability studies and/or additional site
characterization needed to support the proposed remedy. Any sampling
conducted in this regard must have the same support documentation as
required for remedial investigation sampling. The applicable reporting
requirements listed in sections 3.0 and A.8 must be identified in the RAP.
5. A description of the criteria for remedial action completion, including
procedures for post-remedial and confirmatory sampling.
6. Equipment and personnel decontamination procedures.
19
Note: To eliminate ongoing sources of groundwater contamination, the proposed
remedy for soil contamination must demonstrate that that the protection of
groundwater soil remedial goals will be met within five (5) years of
Remedial Action Plan implementation or sooner. If this cannot be
demonstrated, active groundwater remediation is required to control
groundwater contamination caused by ongoing leaching of contaminants.
Also, if, at any time during the first five years of implementation of an
approved RAP it is discovered that site conditions, remedial technologies
or other factors will prevent the remediating party from achieving the
protection of groundwater soil remedial goals within the required time
period the remediating party shall immediately notify the Branch and
active groundwater remediation may also be required.
Note: The remediating party is responsible for developing appropriate health and
safety measures that conform to all applicable federal and state regulations
to ensure that the health and safety all persons on and off-site will not be
adversely affected by any remedial activity.
5.2.4 Planned progress reporting
The remediating party should specify in the RAP the intended progress reporting.
A description of procedures and a schedule for completing construction, operation
and maintenance, system monitoring and performance evaluation, and progress
reporting should also be provided in the RAP. The progress reports must comply
with the terms of the Agreement and the approved RAP. In most cases, the
following reports will be required:
5.2.4.1 Preconstruction report - The content and timetable for submitting
this report must be specified in the RAP. (See section 5.3 for
content requirements.)
5.2.4.2. Construction completion report - The content and timetable for
submitting this report must be specified in the RAP. (See section
5.4 for content requirements.)
5.2.4.3. Periodic progress reports - The content and timetable for progress
reporting must be specified in the RAP. (See section 5.5 for
content requirements.)

in or accompanying this certification is true, accurate, and
complete.”
20
5.2.5.2 A signed and notarized certification by the consultant responsible
for the day to day remedial activities stating, “I certify that, to the
best of my knowledge, after thorough investigation, the
information contained in or accompanying this certification is true,
accurate, and complete.”
5.2.5.3 Any work that would constitute the “practice of engineering” as
defined by G.S. 89C shall be performed under the responsible
charge of, and signed and sealed by, a professional engineer
registered in the state of North Carolina. Any work that would
constitute the “public practice of geology” as defined by G.S. 89E
shall be performed under the responsible charge of, and signed and
sealed by, a geologist licensed in the state of North Carolina.
5.3 Preconstruction Report
After receiving written approval of the RAP from the branch and prior to construction,
the remediating party must submit a preconstruction report. The report must be certified
as described in section 5.2.5 and contain at least the following information.
1. The results of any additional site characterization or treatability studies performed
since branch approval of the RAP.
2. A final engineering report, including a narrative description of process design, a
summary of changes from the conceptual design approved in the RAP and final
construction plans and specifications.
3. Copies of any required registrations, permits, and approvals.
4. A detailed Performance Monitoring and Evaluation Plan that has been developed
to monitor the performance of the remedial action system as shown in the final
design.
5. An updated project schedule that includes estimated submittal dates for the
Construction Completion Report, Progress Reports, and the Remedial Action
Completion Report.
5.4 Construction Completion Report
Within ninety days of construction completion, the remediating party must submit a
construction completion report that includes “as-built” plans and specifications, a
summary of major variances from the final design plans, and a summary of any problems
encountered during construction. The construction completion report must be certified as
described in section 5.2.5.
5.5 Progress Reports
Weekly progress reports will be required during remedial actions of less than three
months duration. Quarterly progress reports will be required for remedial actions of
greater than three months duration. The content of weekly and quarterly progress reports
21
will be specified in the approved RAP. In most cases, the following information will be
required:
1. Operation and maintenance results: summaries of remedial action operating
experience and maintenance requirements, and a discussion of major problems
encountered.
2. Performance evaluation results: tabulated and graphical presentation of
monitoring data, and comparison of remedial action performance to design goals.
Example: Performance evaluation reports for a groundwater remediation system
would include evaluation of impacts on contaminant levels, hydraulic gradients
and recovery well capture zones, evaluation of the treatment train, contaminant
removal efficiencies, total mass of contaminants removed, etc. All results must
include the applicable information shown in section 3.0 and the data reporting
procedures shown in section A.8. Copies of waste manifests are required for any
RCRA hazardous wastes shipped off site.
3. All progress reports must be certified as described in section 5.2.5.
5.6 Remedial Action Completion Report
Within ninety days of remedial action completion, the remediating party must submit a
final report which demonstrates that the remedial action has been completed in
accordance with the approved RAP and in compliance with the Agreement, Site Cleanup
Request Letter, or Order to Develop and Implement a Remedial Action Program. The
final report should include at least the following:
1. A final progress report that includes the information shown in section 5.5.
2. A summary of remedial action operating experience and effectiveness in meeting
design goals, based on all performance monitoring data and progress reporting to

3. A discussion of criteria for remedial action completion, and a demonstration,
supported by confirmation sampling data, that such criteria have been satisfied.
All confirmation sampling results should include the same support documentation
as required for remedial investigation sampling. The applicable reporting
requirements listed in section 3.0 and section A.8 must be identified.
4. A summary of total project costs.
5. Certifications described in section 5.2.5.
Note: To be considered complete, the remedial action must achieve the current remedial
goals at the time of remedial action completion.
A - 1
Appendix A: Sampling and Analytical Procedures for the Remedial
Investigation
A.1 Introduction
This appendix provides general guidance on sampling and analytical procedures. At most sites,
the remediating party will need to prescribe additional sampling and analysis based on site-
specific conditions.
The remedial investigation should include collection of the minimum number of samples
described below, from each area of concern. (Analytical procedures are addressed in section A.7
of this appendix.) Once the first phase of sampling is completed, the branch will review the
information provided and compile a list of contaminants of concern. The second phase of the
remedial investigation should be structured to define the extent of each contaminant in each area
of concern for each medium that is contaminated. The extent of contamination must be
delineated to the remediation goals contained in section 4.0 of this document or site-specific
natural background levels for metals, if less stringent.
Note: All areas known, suspected or having a reasonable probability of being contaminated by
hazardous substances must be investigated. “Areas known, suspected or having a
reasonable probability of being contaminated” includes any media or areas where there is
evidence (such as, but not limited to, allegations or indications of spills, visual
observations, field instrument readings, laboratory data, and chemical odor) of a release
of hazardous substances or of materials that contain or may contain hazardous
substances.
A.2 Soil Sample Collection
A.2.1 Phase I sampling
The purpose of the Phase I soil investigation is to identify all releases of hazardous
substances to site soils, to characterize the chemical nature of such releases, and to collect
sufficient sampling data to establish remediation goals.
Known or suspected spills and disposal areas must be investigated using historical
research, such as waste management records, employee interviews, vintage maps, and
aerial photographs. Samples must be collected from each known or suspected area of
concern. All areas known, suspected or having a reasonable probability of being
contaminated by hazardous substances must be investigated. “Areas known, suspected or
having a reasonable probability of being contaminated” includes any media or areas
where there is evidence (such as, but not limited to, allegations or indications of spills,
visual observations, field instrument readings, laboratory data, and chemical odor) of a
release of hazardous substances or of materials that contain or may contain hazardous
substances. The necessary sampling strategy depends on whether or not there is visible
evidence of contamination.
A - 2
A.2.1.1 Visible evidence of contamination
At least one grab soil sample should be collected centrally from the most
visibly contaminated location and horizon in each area of hazardous substance
release or possible release.
A.2.1.2 No visible evidence of contamination
A.2.1.2.1 Surface release:
a. If no visible evidence exists in an area of a suspected surface
release of contaminants, sampling should be conducted by first
establishing a grid with grid line intersections (nodes) spaced no
farther than 50 feet apart. Samples collected for all analyses
except volatile organics should be collected from 0 to 6 inches
below ground surface at each grid node. Samples collected for
volatile organic analysis should be collected at a depth of 6 to 12
inches below ground surface. Compositing to reduce the total
number of samples may be conducted as follows:
< 62,500 square feet: No more than four adjacent grid node
(250 ft. x 250 ft.) samples may be composited.
> 62,500 square feet: A greater number of adjacent grid node
samples may be composited, but a minimum
of five resulting composite samples should
be submitted for laboratory analysis.
At least five samples or 25% of the node samples, whichever is
greater, should be collected as unmixed grab samples. Field
screening methods may be used to select these unmixed samples or
the unmixed samples should be collected from locations that are
evenly distributed across the area of suspected contamination. The
remaining samples should be collected as either unmixed grab
samples or composited samples. Composited samples will be used
for qualitative data only.
Note: For extremely large sites (sites several acres in size), contact
the branch to discuss site specific conditions.
b. In addition to A.2.1.2.1.a., if the actual contaminants released are
unknown, mobile contaminants or contaminants that have been
detected in groundwater at the site, a soil boring should be
advanced to the water table. The boring should be centrally
located in the area of concern and adequately sampled at intervals
from ground surface to the water table. Examples of sampling
intervals include 0 to 6 inches below ground surface, every five
feet from 6 inches to the water table, and at the water table.
A - 3
A.2.1.2.2 Subsurface release:
a. The results of the historical research should be used to conduct
geophysical surveys and test trenching. Geophysical surveys
should be conducted by scanning areas of concern on parallel and
perpendicular traverses spaced no further than 30 feet apart.
Closer spacing may be required when using a metal detector.
Grids should be established in all areas that yield anomalous
readings during the scanning phase. Grid nodes should be spaced
no greater than 10 feet apart. Readings should be recorded at each
grid node and mapped. If areas are excluded from the survey due
to instrument interference, the remediating party should provide a
written justification for exclusion along with a map delineating the
features causing the interference with the remedial investigation
report.
b. Once the subsurface disposal area has been identified, it should be
sampled in accordance with sections A.2.1.1, A.2.1.2.1 (b) and
A.5.1 (1). If the suspected subsurface disposal area cannot be
located using the methods described above, a soil boring should be
advanced through the suspected disposal area in accordance with
section A.2.1.2.1 (b).
A.2.2 Phase II sampling
The purpose of the Phase II soil investigation is to delineate the lateral and vertical extent
of contamination in each area of concern to concentrations less than or equal to the soil
remediation goals listed in the SRG Table, naturally occurring background levels (metals)
or remediation goals established by the branch. Delineating the extent of soil
contamination requires sampling all ditches, culverts or other drainage features that may
have received runoff from known-contaminated areas. Field screening methods, such as
soil gas testing and immunoassay test kits, may be used to help define the extent of
contamination. If these methods are used, soil samples should also be collected at the
expected vertical and lateral boundaries of each contaminated area and sent to the
laboratory for confirmation.
A.3 Groundwater Sample Collection
A.3.1 Phase I sampling
The purpose of the Phase I groundwater investigation is to identify all releases of
hazardous substances to groundwater, to characterize the chemical nature of the
contaminant plume(s), and to collect sufficient sampling data to establish remediation
goals.
A - 4
The need for groundwater assessment at a site with known soil contamination will be
determined on a case-by-case basis. If the water table is within five feet of the ground
surface, the contaminants are known to extend to within a five-foot depth of the water
table, or the contaminants are somewhat mobile (such as VOCs and leachable metals) the
uppermost groundwater aquifer should be sampled. At least one well should be installed
centrally within each area of release meeting one or more of the above criteria. Where
contaminants are believed to be “floaters” due to density and solubility in water, well
screens should be positioned across the water table. Where contaminants are believed to
be "sinkers," the well screen should be positioned just above the bedrock surface. In
many cases, insufficient information on the nature of hazardous substance releases at the
site will make it necessary to perform the Phase I groundwater field work after the Phase
I soil work is completed.
If the remediating party decides not to install a well within an area due to grossly
contaminated conditions or concern for rupturing buried vessels, a minimum of three
wells must then be installed immediately surrounding the suspect area. Once
groundwater flow patterns are clearly defined, a well will be required on the hydraulically
down gradient perimeter of the area of concern. A previously installed well may be
appropriately located. Depending on the size of the area and nature of the release,
additional monitoring wells may be necessary once the source is removed or remediated.
Groundwater elevation data should be collected during each sampling event and at least
every six months during the remedial investigation. If subsequent water table elevation
data indicate a significant change in the direction of groundwater flow, additional wells
will be necessary to adequately evaluate groundwater contamination. Groundwater
elevations should be measured from a datum established by a professional land surveyor.
A minimum of one sample must be collected from each monitoring well.
A.3.2 Phase II sampling
If Phase I sampling indicates hazardous substances are present in groundwater, additional
groundwater assessment will be required. The purpose of the Phase II groundwater
investigation is to delineate the lateral and vertical extent of all contaminant plumes, on -
and off-site. The lateral and vertical extent of the groundwater contaminant plumes must
be defined by wells free from hazardous substance concentrations that exceed branch
remediation goals.
Note: Site-specific conditions may require more than two phases to complete the
groundwater investigation. Examples include complex hydrogeology, such as
fractured bedrock aquifers, and complex contaminant behavior, such as the
migration of dense non-aqueous phase liquids.
A.4 Surface Water and Sediment Sample Collection
A.4.1 Phase I sampling
The purpose of the Phase I surface water/sediment investigation is to identify all releases
of hazardous substances to surface water or sediments, to characterize the chemical
A - 5
nature of such releases, and to collect sufficient sampling data to establish remediation
goals. Surface water assessment will be necessary if there is a potential for contaminants
to migrate to surface water via surface runoff or through a discharge of contaminated
groundwater to a surface water body. If surface water assessment is required, water and
sediment samples should be collected at the probable point of entry. In addition, at least
one water and one sediment sample must be collected immediately upstream of the site
and one water and one sediment sample collected immediately downstream of the site.
These samples need only be analyzed for contaminants previously detected in other
media at the site unless a non-permitted direct discharge of a hazardous substance from
the site to surface water has occurred. If such a discharge has occurred, samples should
be analyzed for the Phase I analyses described in section A.7.1.
A.4.2 Phase II sampling
If contamination is detected in any downstream sample, additional surface
water/sediment assessment will be required. The purpose of the Phase II surface
water/sediment investigation is to define the downstream extent of contamination to
concentrations less than or equal to the remediation goals established by the branch.
A.5 Other Sample Collection
A.5.1 Phase I sampling
1. If any abandoned or buried vessels containing unknown materials or hazardous
substances are discovered, contact the branch before proceeding with assessment.
Depending on the scope, full characterization may be part of the remedy. When
investigation does occur the contents should be sampled and analyzed for parameters
sufficient to meet disposal or treatment facility requirements. A full scan composite
soil sample(s) in the vessel area should be collected as described in section A.2.1.
Soil samples will also be required at the time of vessel excavation in the immediate
vicinity of all joints and junctures of subsurface pipe associated with any underground
vessels known or suspected to contain or have contained hazardous substances.
2. Waste materials (e.g. fly ash, sludge, etc.) that are known or suspected to contain
hazardous substances that may cause an exposure hazard and contaminate other
media should be evaluated using the same procedures as if it were contaminated soil.
Laboratory analyses are necessary to determine if the contaminants in the waste
materials exceed the branch’s remedial goals. See section A.2 for additional
information
3. Site-specific background soil samples should be collected to establish natural metals
concentrations. Samples should be located away from roadways, railways, parking
areas and other potential sources of contamination. Because natural metals
concentrations are highly variable, the branch recommends collecting a minimum of
five background soil samples. Background soil samples should be collected from
depths and soil types that are representative of contaminated soils, but should not be
collected from topsoil (0-6 inches).
4. If groundwater assessment is required, background groundwater samples should be
A - 6
collected to established natural background conditions. Samples should be collected
upgradient of any on-site sources of contamination.
5. If surface water assessment is required, background surface water and sediment
samples should be collected to establish natural or anthropogenic background
conditions. Samples should be collected upstream of any on-site sources of
contamination. If contamination is found upstream of the site in concentrations
greater than the downstream concentrations, downstream delineation may not be
required.
A.5.2 Phase II sampling
Areas determined to have hazardous substance contamination resulting from a release
from a vessel should be characterized according to section A.2.2.
Note: At sites having any contamination located within 100 ft of an occupied or
potentially occupied building, subsurface vapor intrusion should be considered.
For additional information contact the branch.
A.6 Standard Field Protocols
1. Unless otherwise noted below, field procedures relating to sample collection techniques,
sample containers, sample preservation, equipment decontamination and field
measurement procedures, should comply with the most current version of the U. S.
Environmental Protection Agency (U.S. EPA) Region IV Science and Ecosystem Support
Division (SESD) Field Branches Quality System and Technical Procedures. This
information is available from the USEPA Region IV SESD at:
http://www.epa.gov/region4/sesd/fbqstp/ .
2. In addition to the standard protocols outlined in the U.S. EPA information referenced
above, please observe the following procedures.
a. Field QC samples: (i.) minimum of one duplicate sample, per medium, per container
type, per field day; (ii.) equipment rinsate blanks and VOA trip blanks are strongly
recommended.
Note: If site conditions, sample frequency or number of samples warrant more limited
QA/QC testing, contact the branch.
b. Other than composited samples collected under Section A.2.1.2.1.a., all soil, sediment
and waste samples for volatiles analysis should be collected directly into sample
containers without mixing.
c. All soil sampling and boring locations should be staked and flagged (or surveyed)
until the remedial investigation is complete.
d. A professional land surveyor, registered in North Carolina, must survey all
monitoring well locations.
A - 7
e. Filtration of groundwater samples for metals analysis before acid digestion is not
permitted. Samples must be prepared using Standard Method 3030C “Preliminary
Treatment for Acid-Extractable Metals,” Standard Methods for the Examination of
Water and Wastewater, latest edition. If turbidity is a problem, groundwater samples
should be collected using a low-flow purging and sampling technique. Additional
well development may also be necessary.
f. For surface waters that are very shallow (less than six inches deep), turbulent or
highly turbid, samples may be collected in a separate collection container and then
decanted into the sample container. Samples for organic analysis must be decanted
into the sample container immediately. Samples for metals analysis may be allowed
to settle for a few minutes prior to decanting. All collection containers must be made
of the same materials as the sample container. They must be pre-cleaned and handled
in the same manner.
g. Investigation derived waste or IDW (may include drill cuttings and muds, sampling
materials, purge water, soil and residuals from testing) generated as part of
assessment activities may be discharged or stored in the area of contamination and are
not subject to RCRA permitting as long as the material: (1) stays on site and remains
in the contaminated area, (2) is secured, (3) does not increase the spread of
contamination or concentrations in a particular medium, (4) does not cause
mobilization of contaminants, and (5) does not introduce contamination to
uncontaminated soil (causing an increase in contaminant concentrations). In
residential and public use areas, IDW will require off-property management unless it
meets unrestricted use levels and disposal permission has been granted by the
property owner. IDW cannot be transferred and discharged to another area of
concern.
A.7 Sample Analyses
The remediating party must provide the laboratory with copies of Sections A.7 and A.8 of this
Guidance document to ensure that appropriate analyte lists are used in the analysis of samples.
A.7.1 Phase I analyses
A.7.1.1 Analytical parameters
Each Phase I sample should be analyzed for:
1. Concentrations (Totals Analysis) of hazardous substance list metals including
antimony, arsenic, beryllium, cadmium, chromium, copper, lead, manganese,
mercury, nickel, selenium, silver, thallium and zinc.
Note: If chromium is a known or suspected contaminant at a site, Phase I
samples should also be analyzed for hexavalent chromium. Also, if
total non-speciated chromium concentrations (by totals analysis) in the
Phase I samples exceed site specific natural background concentrations
and the hexavalent chromium soil remedial goals, hexavalent chromium
A - 8
analyses will also be required. This analysis can be done during Phase
I by collecting a sufficient sample volume to run hexavalent analyses
should the total chromium result exceed the hexavalent soil remedial
goal. Alternatively, this testing could be performed during the next
phase of work.
2. All volatile and semi-volatile compounds on the method analyte list using the
analytical methods specified in Section A.7.1.2 with a library search (using
the National Institute of Standards and Technology mass spectral library) to
produce a list of tentatively identified compounds. The library search should
identify TICs for the largest 10 peaks in each analytical fraction that have
reasonable agreement with reference spectra (i.e., relative intensities of major
ions agree within ± 20%). The list of identified TICs should not include
laboratory control sample compounds, surrogates, matrix spike compounds,
internal standards, system monitoring compounds or target compounds. Any
TICs that have reasonable agreement with reference spectra, and are detected
in more than one sample, should be included in all subsequent analytical work
unless the remediating party can prove the compound is a laboratory
contaminant. Quantification of these specific TICs must be performed before
cleanup levels can be determined.
3. Pesticides, PCBs, dioxins, cyanide, formaldehyde, ammonia, nitrates, nitrites,
phosphorous and any other CERCLA hazardous substances or pollutants not
specifically mentioned here, if the remediating party suspects they were used
at the site based on its chemical usage history.
Note: In most cases the above listed parameters must be included in the first
phases of testing each contaminated media. Typically, the contaminants
for an area of concern at an inactive hazardous site are not clearly
understood or are unknown due to the uncertainty of past practices at the
site (e.g. poor recordkeeping of disposal practices, uncertainty of the
business practices of a previous property owner or operator, etc.). If the
remediating party believes some of the above analyses should be
excluded, the remediating party should contact the branch to discuss the
site specific conditions before excluding analyses.
A.7.1.2 Analytical methods
The analytical methods used to test for the Phase I parameters outlined in
Section A.7.1.1 should be the most recent, U.S. EPA- approved update of the
following analytical methods:
Soil and sediment samples
Volatile Organic Compounds Method 8260*
Semi-volatile Organic Compounds Method 8270*
Pesticides Method 8081
PCBs Method 8082
Metals (total concentrations) SW-846 Methods
A - 9
Dioxins, cyanide, formaldehyde U.S. EPA method
and any other analytes not covered having the lowest
by above methods method detection limit
*: With a library search as described in Section A.7.1.1.
Water samples (including groundwater, surface water and TCLP leachate)
Volatile Organic Compounds Method 8260*
Semi-volatile Organic Compounds Method 8270*
Pesticides Method 8081
PCBs Method 8082
Metals, dioxins, cyanide, formaldehyde U.S. EPA method
and any other analytes not covered by capable of achieving
above methods method detection limits less
than or equal to the
applicable 15A NCAC 2L
groundwater standard.
*: With a library search as described in Section A.7.1.1.
Note 1: Standard Method 3030C “Preliminary Treatment for Acid-Extractable
Metals,” Standard Methods for the Examination of Water and
Wastewater, latest edition, must be used in metals analyses of water
samples. Filtration of groundwater and surface water samples before
acid digestion is not permitted. Highly turbid water samples for metals
analysis should be collected in accordance with Appendix A, section
A.6 (2)(e) and (f).
Note 2: To demonstrate compliance with the branch’s soil remediation goals
for the protection of groundwater, the laboratory must achieve sample
quantitation limits less than or equal to the Subchapter 2L groundwater
standards. Alternatively, they must state in the case narrative that the
sample quantitation limits are the lowest that can be achieved using
U.S. EPA-approved methods.
A.7.2 Phase II analyses
A.7.2.1 Analytical parameters
After the first phase of sampling is conducted as specified in sections A.2 through
A.5 above, any samples subsequently collected need only be analyzed for the
following compounds.
1. TICs that meet the criteria in section A.7.1.1 (2) that are also CERCLA hazardous
substances must be quantified in Phase II analyses using U.S. EPA methods that
have the lowest method detection limit. If no U.S. EPA method exists for a
particular compound, the best available analytical method should be used.
A - 10
2. All CERCLA hazardous substances present above method detection limits, unless
the contaminant concentration is proven through sampling to be the result of a
naturally-occurring condition, or the contaminant is a common laboratory
contaminant detected in concentrations below that detected in the method blank.
If a compound that is not a common laboratory contaminant is detected in both
the blank and a sample, another phase of sampling is necessary to demonstrate the
absence or presence of the contaminant.
3. Potential degradation compounds (which are also CERCLA hazardous
substances) of those CERCLA hazardous substances detected at the site.
4. If total chromium concentrations in the Phase I samples exceed site specific
natural background concentrations and the hexavalent chromium soil remedial
goals, hexavalent chromium analyses are required.
5. If laboratory sample dilutions were performed on Phase I samples, Phase II
samples must be analyzed for the entire analytical fraction previously diluted in
addition to the above items. Sample dilutions raise analytical detection limits and
can mask the presence of other constituents at lower concentrations.
A.7.2.2 Analytical methods
Phase II and subsequent samples should be analyzed using the methods specified
above for Phase I samples. Other U.S. EPA-approved methods may be
substituted, if the substitute methods achieve equal or lower method detection
limits.
A.8 Data Reporting
Laboratory reports submitted with remedial investigation reports must include the items listed
below. Full CLP documentation packages are not required.
1. The laboratory report must state that the laboratory is either certified for applicable
parameters under 15A NCAC Subchapter 2H .0800, or that it is a contract laboratory under
the U.S. EPA's Contract Laboratory Program.
2. A signed statement from the laboratory that the samples were received in good condition, at
the required temperature and that analysis of the samples complied with all procedures
outlined in U.S. EPA methodology, unless otherwise specified. Any deviation from the
methods, additional sample preparation, sample dilution and unrectified analytical problems,
must be justified in a narrative with the laboratory report.
3. Laboratory sheets for all analytical results, including sample identification, sampling dates,
date samples were received by laboratory, extraction dates, analysis dates, analytical methods
used, dilution factors and sample quantitation limits.
Note: The laboratory must provide a written explanation for any sample having sample
quantitation limits that exceed 10 times the U.S. EPA method detection limits.
A - 11
4. Laboratory sheets for all laboratory quality control samples, including results for bias and
precision and control limits used. The following minimum laboratory quality control sample
reporting is required: (a) at least one matrix spike and one matrix spike duplicate per sample
delivery group or 14-day period, whichever is more frequent (control limits must be
specified); (b) at least one method blank per sample delivery group or 12-hour period,
whichever is less; and (c) system monitoring compounds, surrogate recovery required by the
method and laboratory control sample analysis (acceptance criteria must be specified). All
samples that exceed control limits/acceptance criteria must be flagged in the laboratory
report.
5. The results of any library searches performed for “tentatively identified compounds.” The
library search must identify TICs for the largest 10 peaks in each analytical fraction that have
reasonable agreement with reference spectra (i.e., relative intensities of major ions agree
within ± 20%) and provide percent probabilities of match. TICs should not include
compounds which are laboratory control sample compounds, internal standards, surrogates,
matrix spike compounds, system monitoring compounds and target compounds. Any
identified TICs should be evaluated by the remediating party to determine the correlation to
any contaminant source materials.
6. Data quality should be reviewed and validated by both the remediating party and the
laboratory. Any quality control concerns, data qualifiers or flags should be evaluated and
discussed in the associated report.
7. All constituents detected must be reported even if they were not definitively quantified. All
estimated concentrations with data qualifiers must be reported.
8. Completed chain-of-custody with associated air bill (if applicable) attached.
9. The laboratory report should include the names of the individuals performing each analysis,
the quality assurance officer reviewing the data and the laboratory manager.
B - 1
Appendix B: Procedures for Confirmation
Sampling and Analysis
B.1 Introduction
This appendix provides general guidance on “post-remediation” sampling and analyses required
to demonstrate compliance with branch remediation goals. At most sites, the remediating party
will need to prescribe additional sampling and analysis based on site-specific conditions.
B.2 Soil Sampling
B.2.1 Post in-situ remediation
For in-situ soil remedies, such as soil vapor extraction, confirmation sampling should be
designed to verify that the entire soil column has been remediated to below branch
remediation goals. The remediating party must design a three-dimensional sampling grid
that meets the four requirements below.
1. Design a surface sampling grid over the area(s) of concern. Grid nodes should be no
more than 50 feet apart.
2. At each grid node, specify “candidate” sampling locations at the surface, at 0 - 6 inches
below ground surface, and at 5-foot intervals (or less) down to the vertical limit of
contamination. The result is a three-dimensional grid of "candidate" sampling locations
that encompasses the area of concern.
3. Select at least two candidate locations at each grid node for sample collection, using a
combination of random and biased selection. Biased samples should be collected from
known “hot spots” and from soil zones that are known to be resistant to in-situ methods
(e.g., clay lenses).
4. Same-depth samples from up to four adjacent grid nodes may be composited. Samples
at different depths may not be composited. For samples submitted for volatiles analysis,
at least five samples or 25% of the node samples, whichever is greater, must be unmixed
grab samples. Field screening methods may be used to select these unmixed samples, or
the unmixed samples should be collected from locations that are evenly distributed
across the area of suspected contamination. The remaining samples should be collected
as either unmixed grab samples or composited samples. Composited samples will be
used for qualitative data only.
B.2.2 Post ex-situ remediation
B.2.2.1 Post-excavation sampling
Post-excavation sampling must be designed to verify that all soils/wastes above
branch remediation goals have been removed. Excavations should be sampled
using the four requirements below.
B - 2
1. Design a sampling grid over the base and sidewalls of the excavation. Grid
nodes should be no more than 50 feet apart. At each grid node, collect a
sample from 0-3 inches into the base or sidewall.
2. For very small excavations, collect at least one composite sample from the
base and one composite sample from each sidewall. Composite samples
should consist of at least four aliquots each.
3. Biased samples should also be collected from areas of residual contamination,
based on visible or field-screening evidence.
4. For excavations <62,500 square feet (surface area), samples from up to four
adjacent grid nodes may be composited. For excavations > 62,500 square feet
(surface area), a greater number of grid nodes may be composited, but a
minimum of five resulting composite samples should be submitted for
laboratory analysis. For all excavations, samples from different sidewalls may
not be composited. For samples submitted for volatiles analysis, at least five
samples or 25% of the node samples, whichever is greater, should be unmixed
grab samples. Field screening methods may be used to select these unmixed
samples, or the unmixed samples should be collected from locations that are
evenly distributed across the area of suspected contamination. The remaining
samples should be collected as either unmixed grab samples or composited
samples. Composited samples will be used for qualitative data only.
B.2.2.2 Treated soil stockpiles
Treated soils/wastes must meet branch remediation goals before they can be
replaced on site. Treated soil stockpiles should be sampled using the following
four procedures.
1. Stockpiles should be divided into equal segments of approximately 100 cubic
yards each.
2. Within each segment, use either random or biased selection to locate at least
three hand-auger borings. Samples should be collected from two depths
within each boring (minimum six samples per segment).
3. Use visible or field-screening evidence to collect additional biased samples
from areas of residual contamination.
4. Samples may be composited only within each segment. For samples
submitted for volatiles analysis, at least 25% should be collected as unmixed
grab samples.
B.3 Groundwater Sampling
Confirmation sampling must demonstrate that site groundwater has been remediated to below
branch remediation goals. Demonstrate this using the following procedures.
B - 3
1. Groundwater remediation systems may be shut down when two consecutive semi-annual
(twice a year) sampling events demonstrate that all monitoring wells (on-site and off-site) are
free of contamination above branch remediation goals. To account for the effects of seasonal
fluctuations in the water table, semi-annual sampling events should be conducted in winter
and summer.
2. Following system shutdown, data from at least four consecutive quarterly sampling events
should demonstrate that all monitoring wells are free of contamination above branch
remediation goals and contaminant concentrations are not increasing.
B.4 Surface Water/Sediment Sampling
Confirmation sampling must demonstrate that site surface water and sediment have been
remediated to concentrations below branch remediation goals. Four consecutive quarterly
sampling events should demonstrate that concentrations in downstream samples are less than or
equal to concentrations in upstream samples. Alternatively, demonstrate that concentrations in
downstream samples are less than or equal to branch remediation goals.
B.5 Confirmation Sample Analyses
Confirmation sampling should demonstrate that all contaminants identified during the remedial
investigation meet applicable remedial goals.
All confirmation samples should be analyzed for all contaminants identified during the remedial
investigation. Confirmation samples must be analyzed using U.S. EPA methods with detection
limits less than or equal to branch remediation goals, or U.S. EPA methods with the lowest
available detection limits for each contaminant of concern.
This appendix provides general guidance on the minimum “post-remediation” sampling and
analyses necessary to demonstrate compliance with branch remediation goals. At most sites, the
remediating party will need to prescribe additional sampling and analysis based on site-specific
conditions.

Appendix D: Land Use Restrictions
D.1 Approval Process for Use of Land Use Restrictions as a Remedy
When unrestricted land use cleanup levels for soil and sediment contamination cannot be
achieved, land use restrictions must be proposed as part or all of a site remedy. This
remedy should be supported by the results of the feasibility study (see section 5.2.2).
Depending on contaminant concentrations and the site's proposed restricted use;
additional remedial action may or may not be required.
Upon completion of a branch-approved remedial investigation, cleanup levels for the
standard industrial/commercial exposure scenario will be provided upon written request.
The remediating party should calculate cleanup levels for other site specific exposure
scenarios (park settings, restricted access, etc.). A risk assessor familiar with the U.S.
EPA risk assessment procedures should conduct this work. If the remediating party
calculates cleanup levels, all supporting risk and exposure assessment calculations must
be provided for the branch’s review and approval. In general, the use of physical barriers
as a remedy for contaminated soils is the least favored option. The most favored option
for contaminated soils is to restore the area as close as possible to unrestricted use
remediation goals. If restoration to unrestricted use levels is not the preferred option
based on the outcome of the feasibility evaluation, cleanup to industrial use levels (or
other alternate scenario levels) is preferred over the use of physical barriers.
Contaminant removal to levels acceptable for the proposed site use, rather than the
placement of barriers, leaves the site with the most flexibility for use. It also provides the
least chance for restrictive covenants to fail to adequately protect human health. If the
feasibility evaluation results in a barrier-type remedy being the most suitable for the site,
direct contact cleanup goals may not apply. However, as with all cases, the protection of
groundwater criterion must be met.
The following steps outline the process that the remediating party should follow for
approval of remedies involving land use restrictions.
1. The remediating party notifies the branch in writing that it proposes the use of land
use restrictions at a site. The notification letter should include either a request for
standard industrial/commercial cleanup levels or indicate that site specific cleanup
levels will be calculated. The remediating party should include descriptions of the
current site and surrounding property use, the site’s proposed future use, and current
and proposed zoning of the site and surrounding properties.
2. The remediating party submits a draft RAP that includes a land use restriction
proposal. The land use restriction proposal should contain the following elements.
a. A proposal stating what activities and uses should be restricted at the site.
Examples of possibly precluded activities are:
- Construction of buildings and other man-made structures;
D - 2
- Excavating, dredging or otherwise removing soils and sediments at all, or
below specified depths;
- Planting or removal of vegetation including edible varieties, trees and shrubs;
and
- Limitations on site use (e.g., preclusion of all uses other than
industrial/commercial).
b. The deed book and page numbers for the property or properties where the
restrictions will apply, if approved.
c. The plat book and page numbers for any “Notice of an Inactive Hazardous
Substance or Waste Disposal Site” (Notice) already recorded in relation to the
site.
d. Proposed remediation goals for restricted land use.
Note: The remediating party must provide all supporting risk and exposure
assessment calculations if a site specific exposure scenario is
proposed.
e. Written consent by the owner(s) of the site to the imposition of land use
restrictions using the form provided in section D.2.
f. A proposed inspection plan for the site to verify that the recorded land use
restrictions are in place and activities at the site are in compliance with these
restrictions. The proposed inspection plan should be included in the section of
the RAP that describes planned inspection, maintenance and progress reporting.
Note: The site owner or remediating party will be required to conduct an
inspection of the site no less than annually. They must also submit a
signed and notarized statement stating that the land use restrictions are
still in effect and that conditions at the site are not in violation of the
land use restrictions. The branch may later supply a form for such
purposes. Owners, operators and other responsible parties are required
under N.C.G.S. 130A-310.3(f) to enforce the land use restrictions and
are expected to take action immediately upon discovery of a violation
of the land use restrictions. Failure to do so will cause automatic
revocation of branch approval of the remedial action.
3. After reviewing the proposal, the branch will approve, reject or provide comments on
the proposal. If an agreement is reached on the proposal, the branch will transmit the
land use restriction document to the remediating party as it is to be recorded. If the
document is acceptable to the remediating party and the site owner, a final RAP
including the land use restrictions document as an appendix, must be submitted.
Upon receipt, the branch will initiate the 30-day public comment period in
accordance with G.S. 130A-310.4(c) (2).
D - 3
4. During the RAP public notice period, the remediating party should submit a draft
Notice to the branch for review. The Notice takes the form of a site survey plat
prepared in accordance with N.C.G.S. 130A-310.8 and branch guidance. The Notice
must contain the following statement: Land Use Restrictions for this site are
recorded in Book ___ and Page ___. The branch will not issue approval to proceed
with recordation of the land use restrictions until the branch has received the draft
Notice and concludes it is complete.
Note 1: The required reference to the recorded land use restrictions (i.e. book and
page numbers) are not expected to be inserted at this time because they
have not yet been assigned.
Note 2: If a Notice for the site has already been approved by the branch and
properly recorded, the new Notice shall contain the following note:
“THIS NOTICE OF INACTIVE HAZARDOUS SUBSTANCE OR WASTE
DISPOSAL SITE SUPERSEDES ALL PREVIOUSLY RECORDED NOTICES OF
INACTIVE HAZARDOUS SUBSTANCE OR WASTE DISPOSAL SITE FOR
THIS PROPERTY.”
5. After the RAP public notice period concludes, the branch will provide written
approval of the RAP and notify the remediating party to proceed with implementation
of the RAP. Upon receipt of written approval of the RAP, the remediating party must
return original signed copies of the final version of the land use restriction document
and Notice to the branch. Upon receipt, the Chief of the Superfund Section will sign
and formally approve these documents. The signed documents will then be returned
to the remediating party for recording in the appropriate Register of Deeds office.
The documents must also be recorded in the grantor index under the names of the
owners of all affected property.
Note 1: These documents should be recorded in the following order: (1) land use
restriction document, (2) Notice (only after the Book and Page number
where the land use restriction document has been recorded have been
entered on the Notice).
Note 2:The remediating party should only record a land use restrictions document
and Notice that have been approved by the branch and contain the
signature of the Chief of the Superfund Section.
6. Within a time period specified by the branch, the remediating party must submit
certified copies of both the recorded land use restrictions document and Notice and
copies of the relevant grantor index page(s) to the branch.
Note: The timing of document recordation during remedial action
implementation is dependent on site conditions and the proposed remedy.
Failure to comply with document submittal deadlines issued by the branch
will cause automatic revocation of the branch’s approval of the RAP.
D - 4
D.2 Land Use Restrictions Consent Form
One of the following forms (Form D-1 Individual Ownership or Form D-2-Corporate

D.3 Cancellation of Land Use Restrictions
If the owner believes that all hazards have been removed and that hazardous substances
are no longer present at the site above unrestricted use remediation goals, the owner may
subsequently request branch approval to cancel the land use restrictions. Canceling land
use restrictions without prior branch approval will cause automatic revocation of
approval of the RAP and will subject the party taking such action to enforcement.

Appendix E: Procedures for Demonstrating Attainment of
Health-Based Soil Remedial Goals Through Averaging
Contaminant Concentrations
Cleanup levels for soils under the Inactive Hazardous Sites Program have three components.
These are the “health-based remedial goal, the protection of groundwater remedial goal and, if
applicable, the ecological risk component. All must be met at the site.
Averaging of contaminant concentrations in soil may be used in demonstrating attainment of
health-based cleanup levels. All of the following conditions apply to the use of such averaging.
Only sample points within one-quarter acre sectors may be averaged for comparison to
unrestricted use levels. Restricted industrial use (land use restrictions approved as part of
the remedial action plan) may allow for averaging over larger areas if the access and use
across the area is consistent. Remote areas and areas of less frequent access may not be
included in the industrial restricted-use averaging
Samples must be evenly spaced over the zone of averaging.
Only samples of the same vertical horizon may be averaged (0-6 inches for surface
samples and no more than 5-foot vertical spread for subsurface samples.
The quarter-acre zone may be a circle, a square or a triangle of generally equal sides.
One dimension of the zone’s perimeter may not be disproportionately longer than
another.
Only actual sample data may be used for all points included in the average and not
published averages for background concentrations.
The sample detection limit must be used for points where concentrations are at or below
detection limits.
Clearly distinct areas of known or suspected releases or visibly delineable areas (visual
characteristics define the areas that exceed cleanup levels) should not be included in any
areal averaging. These releases should be delineated and addressed separately.
Clean areas adjoining the area of release should not be included in the average even if the
area of release is less than a ¼ acre.
No single sample point may exceed ten times the site-specific adjusted cleanup level for
all contaminants except lead. For contaminants where the limit on the maximum sample
E - 2
point concentration is based on a carcinogenic effect cleanup level, the limit on the
maximum sample point concentration for averaging may be waived if a demonstration is
made to show that the sample point exceeding the maximum does not represent a separate
area of disposal/release. For contaminants with both carcinogenic and non-carcinogenic
effects, and where the carcinogenic maximum sample point limit is lower and is waived,
the non-carcinogenic maximum sample concentration would apply. The non-
carcinogenic limit may not be waived. For lead, no single sample point used in an
average may exceed 1000 ppm for unrestricted use and no more than three times the site-
specific cleanup level for restricted use.
Composite sample results may be included in an average, but must be weighted
proportionally to the area they represent. For example, if one composite sample in an
area represents ½ of the area and 5 others represent 1/10 of the area each, then the
concentration of the first composite should be multiplied by 5, added to the sum of the
other concentrations and then divided by 10 to compute the average concentration.
For characterizing soil concentrations over an area, a sampling grid with 50-foot grid
node spacing must be established. For large areas that can be demonstrated to have had a
consistent use and release of contaminants, sampling grids can be set up with larger grid
node spacing than 50 feet. However in such cases, the concentrations may not be
averaged in quarter acre zones. The upper end of the range of concentrations is presumed
to represent the entire area. No averaging may be conducted. If the upper end
concentration exceeds unrestricted use cleanup levels, the area would require cleanup or
land use restrictions. If the contaminant concentrations exceed the restricted-use levels
based on the intended use, an alternative for larger areas is to take one or more large
zones within the overall area that represent the range of environmental conditions present
(various geologic and geographic conditions such as slope vs. valley, wetter vs. drier) to
represent the overall area. Grids with 50-foot node spacing should be established across
these representative areas. This approach requires the area to be of consistent use and
access and requires land use restrictions as part of the remedy.
For unique circumstances, contact the Inactive Hazardous Sites Branch for further
guidance.

PRELIMINARY SOIL REMEDIATION GOALS (PSRG) TABLE
(Updated First & Third Quarter of Calendar Year)
AUGUST 2011
Both health-based and protection of groundwater remediation goals must be met. The protection of groundwater remediation
goals listed on this table are only one alternative for achieving protection of groundwater criteria. Please refer to REC or State–
lead Guidance documents for additional information on protection of groundwater remediation goals, procedures for adjusting
preliminary remedial goals and other criteria that may affect remediation goals (e.g. ecological receptors, cross-media
contamination). In addition, if sensitive environments are present, the branch may require the adjustment of remediation goals
and/or the proposed remedial alternative. Values revised since last edition are in bold.

1 - Preliminary health-based soil remediation goals (PSRGs) (adapted from the June 2011 USEPA Regional Screening Tables
(RSL.) http://www.epa.gov/reg3hwmd/risk/human/rb-concentration_table/Generic_Tables/index.htm
- The lower of the carcinogenic remediation goal at 1.0E-06 risk, the non-carcinogenic remediation goal at a hazard quotient
of 0.2, the chemical specific soil saturation concentration (Csat), and the Ceiling Concentration – Max (100,000 mg/kg) is
listed.
- Industrial Remediation Goals can only be used with Branch approval and land use restrictions. Industrial PSRGs cannot be
used for properties occupied or frequented by children.
- Determine if a chemical has both carcinogenic and non-carcinogenic properties from the USEPA RSL Supporting Tables
before adjusting, as prescribed in the guidance.
2 - Developed using a soil leachate model using default values appropriate for North Carolina (see pg. 18). For chemicals with
no protection of groundwater remediation goal call the Branch or refer to the guidance. Protection of groundwater
remediation goals can be developed using other methods described in Branch Guidance.
3 - Based on North Carolina 2L as target groundwater concentration.
4 - Based on North Carolina Interim 2L as target groundwater concentration.
5 - The preliminary remediation goals for dioxins and furans can also be calculated as a toxic equivalency concentration (TEQ)
by using the toxicity equivalence factor (TEF) methodology. (See TEF table for dioxins and furans.)
6 - The SRG is based on USEPA guidance on lead cleanup levels. The value cannot be adjusted.
7 - The SRG is based on USEPA policy for cleanup of PCBs at Superfund Sites. The Branch is currently reviewing the PCB
remediation goal policy and may issue further guidance at a later date.
8 - Remediation goals for carcinogenic PAHs can also be calculated as a toxic equivalency concentration (TEQ) by using the
toxicity equivalence factor (TEF) methodology. (See TEF table for carcinogenic PAHs.)
9 - C - The PSRG is based on the carcinogenic endpoint and corresponds to an excess lifetime cancer risk of 1 in 1,000,000.
N - The PSRG is based on the non-carcinogenic endpoint and corresponds to a hazard quotient of 0.2.
M - Contaminant is a mutagen.
Csat – Soil Saturation Concentration.
Max – Ceiling Concentration (100,000 mg/kg).
N/A- Not available.
