NORTH CAROLINA BROWNFIELDS REDEVELOPMENT SECTION
ENVIRONMENTAL MANAGEMENT PLAN
This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Redevelopment Section at the direction of a Brownfields
project manager.
The EMP is a standard requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during demolition and construction at Brownfields properties in an effort
to avoid delays in the event of the discovery of new contamination sources or other
environmental conditions. The EMP provides a means to document redevelopment plans and
environmental data for each applicable environmental medium to inform regulatory -compliant
decision -making at the site. As much detail as possible should be included in the EMP,
including contingency planning for unknowns. Consult your project manager if you have
questions.
Prospective Developers and/or their consultants must complete and submit this form and all
pertinent attachments, see checklist below, to their Brownfields project manager prior to any
earthmoving or other development -related activities that have the potential to disturb soil at
the Brownfields Property, including demolition. For the EMP to be valid for use, it must be
completed, reviewed by the Section, signed by all parties working on the project, and
approved by the Brownfields project manager. Failure to comply with the requirements of the
EMP could jeopardize project eligibility, or in the event of a recorded agreement, be cause for
a reopener.
The EMP is valid only for the scope of work described herein and must be updated to be
applicable for new phases of redevelopment or after significant changes in applicable
regulatory guidance. Risk characterization of a Brownfields Property to DEQ's written
satisfaction is required prior to EMP approval.
Voluntary Metrics Tab
The NC Brownfields Redevelopment Section updates estimated capital investment (from the
Brownfields Property Application) and estimated jobs created (from the Brownfields
Agreement) whenever possible. As a voluntary measure, you may opt to complete the below
information for capital investment and jobs created as estimated by your final redevelopment
plans for the Brownfields Property:
1. Estimated capital investment in redevelopment project: $50,000,000
2. Estimated jobs created:
a. Construction Jobs: TBD
b. Full Time Post -Redevelopment Jobs: Jobs associated with the multi -modal
public transportation center and businesses within the building.

PART 1. SOIL
1) Known or suspected contaminants in soil (list general groups of contaminants):
Soil assessment activities took place in February 2004 (2 borings) and January 2021 (4 borings).
The February 2004 assessment consisted of the collection of grab samples analyzed for volatile
organic compounds (VOCs), semi -volatile organic compounds (SVOCs), and Resource
Conservation and Recovery Act (RCRA) 8 Metals. Samples collected in January 2021 consisted of
grab samples for analysis of VOCs and composite samples for analysis of SVOCs, RCRA 8 Metals,
Mercury, and Hexavalent Chromium. The tables included in the appendix lists the contaminants
measured in soil and provides a comparison to Residential Preliminary Soil Remediation Goals
(PSRGs). Since groundwater is proposed for restriction, the Protection of Groundwater PSRGs are
not presented in the tables. Polynuclear aromatic hydrocarbons (PAHs) and RCRA 8 metals were
detected in soil samples above residential PSRGs or in cases where there is no established
screening level. See Table 3 attached to the EMP for detected concentrations.
2) Depth of known or suspected contaminants (feet):
Contamination is estimated to be at least 3 feet below land surface.
3) Area of soil disturbed by redevelopment (square feet):
The redevelopment site is 1.739 acres in size. Deep foundations/piles are located across the
entire site.
4) Depths of soil to be excavated (feet):
Soil may be excavated at depths up to 80 feet associated with deep foundation/pile work. Minor
amounts of soil will be excavated during utility install.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Approximately 10,000 to 15,000 cubic yards total.
4,000 cubic yards are anticipated from deep foundations/pile with the remainder of soil coming
from locations across the site during grading, including the former basement that was backfilled
with beneficial reuse fill from Lake Wheeler Assemblage Brownfields site.
8
EMP Version 3, March 2023

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Limited impacts are expected based on depth of deep foundations/piles and beneficial fill
imported to site during demolition and backfilling of former basement.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Limited impacts are expected based on depth of deep foundations/piles and beneficial fill
imported to site during demolition and backfilling of former basement. Approximately 10,000 to
15,000 cubic yards total are anticipated for export.
PART 1.A. MANAGING ONSITE SOIL

❑ Other. Please provide a description of the measure:
4) Please describe the following action(s) to be taken during and following excavation and
management of site soils:
Management of fugitive dust from site
® Check to confirm that management of fugitive dust from site activities will be handled in
accordance with applicable local, state, and federal requirements.
As needed, monitoring of fugitive dust will be conducted in accordance with typical construction
practices. Soils that are dry and have the potential to migrate through air from the site will be
managed in accordance with typical construction practices, which will take the form of a light,
periodic application of water via a water truck to moisten soils and reduce airborne dust.
Field screening of site soil
At a minimum, contractors shall be made aware of protocols should impacted soils (e.g. staining,
unusual odors, fill materials) be identified.
Describe the field screening method, frequency of field screening, person conducting field
screening:
Soils will be screened by a Qualified Environmental Professional (QEP) if visible discoloration
and/or odors are discovered during grading/excavation activities. If observed, the suspected
soils will be screened with a photo -ionization detector (PID) to identify relative concentrations
and evaluate the need for sampling and laboratory analysis.
Additional screening in other areas of the site will not be conducted beyond visual observation
for discoloration and/or odors by on -site construction personnel with a QEP on -call as needed
during grading activities. Based on sampling conducted across the site and lack of potential
sources of contamination, additional screening is not warranted.
Soil sample collection
❑ Yes
® Not anticipated - In order to avoid delays in construction, a plan shall be in place for sampling
of suspect soils should they be encountered during redevelopment. If soil sample collection is
not anticipated but the need to do so is identified during redevelopment, notify the Brownfields
project manager of the anticipated sample and report dates for scheduling purposes.
Describe the sampling method (e.g., in -situ grab, composite, stockpile, etc.) and confirm that all
procedures outlined in applicable DEQ guidance for assessment shall be followed Typically, at
least one representative sample (per 500 yd'for residential and 1,000 yd3 for commercial)
consisting of a 3 to 5-point composite sample with grab sample for VOCs based on the highest PID
reading is required to determine soil management options:
If during deep foundation/pile work, impacted soils are discovered, procedures for
screening and sampling the soils will be implemented as described in the section for
11
EMP Version 3, March 2023

"Contingency for encountering unknown tanks, drums, or other waste materials". Visual
observation for discoloration and/or odors will be made by on -site construction personnel
with a QEP on -call as needed during grading activities
Check applicable chemical analytes for soil samples:
® Minimum Sample Requirements: Volatile organic compounds (VOCs) by EPA Method
8260; Semi -volatile organic compounds (SVOCs) by EPA Method 8270; and Metals RCRA
List + Hexavalent Chromium by EPA Method 6020/7199

® Other Constituents & Respective Analytical Method(s) (e.g. Herbicides):
Hexavalent Chromium via EPA Method 7199 will be run on the soil sample with the
highest total chromium laboratory result. In the case of soil stockpiles, if the
hexavalent chromium analysis of that sample is below the hexavalent chromium
PSRG, then the soil in the stockpile is considered to be below the hexavalent
chromium PSRG.
® Check to confirm that by the owner's signature and the North Carolina Professional
Engineer/Geologist sealing this EMP the consultant understands that no work plan for suspect
soil sample collection will be submitted beyond this EMP, and that it is the responsibility of the
sealing professional and property owner to ensure that all applicable guidelines and
methodologies are followed and reported to DEQ for determination and approval of soil
placement prior to final relocation.
If impacted soils above applicable PSRGs and/or site specific risk thresholds are proposed to be
relocated on -site, prior to final placement on -site, the following shall be submitted for DEQ
review/approval
- Analytical data that has been sampled in accordance with the above referenced frequency and

sample collection will be submitted beyond this EMP, and that it is the responsibility of the sealing
professional and property owner to ensure that all applicable guidelines are followed and reported in
the Soil Export Request for DEQ approval. Failure to meet these requirements could result in
resampling and/or failure to approve export.
If other special considerations apply, discuss:
PART I.D. MANAGEMENT OF UTILITY TRENCHES
❑ Install liner between native impacted soils and base of utility trench before filling with clean fill
(Preferred)
16
EMP Version 3, March 2023

® Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a
hazardous waste), i.e., impacted soils are placed back at approximately the depths they were
removed from such that impacted soil is not placed at a greater depth than the original depth
from which it was excavated.
® Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport,
and/or degradation of conduit materials due to direct impact with contaminants.
® If yes, provide specifications on barrier materials or provide the results of this evaluation in the
Vapor Mitigation Plan. Note that if vapor mitigation is planned for site buildings, utility corridors
will need to be evaluated as part of mitigation designs:
During the design of the planned VIMS for the site, the need for barriers in utility conduits will be
evaluated.
❑ If no, include rationale here:
uiici< or tap nere to enter text.
❑ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings
Other comments regarding managing impacted soil in utility trenches:
Concerns and methods for handling of soils do not preclude nor modify any of the Occupational
Safety and Health Administration (OSHA) requirements for worker safety incumbent upon
contractors for regular site safety and trenching/excavation activities. Workers should be aware
of the possibility of contaminated soil in the utility trenches. Workers will don appropriate
personal protective equipment, and mitigation measures such as venting, and limiting worker
entry into trenches and other subsurface work areas as much as is feasible will be taken.
Workers will be informed to look for signs of contaminated soil including staining, discoloration,
and strong odors during utility trenching. If potentially contaminated soil is encountered during
trenching, the contractor should notify the QEP and field screening of air space should be
conducted during work.
PART 2. GROUNDWATER
1) What is the depth to groundwater at the Brownfields Property?
Depth to groundwater ranges from approximately 11 ft bls in the northern portion of the site to
19 ft bls in the southern portion of the site.
2) What is the maximum depth of soil disturbance onsite?
Deep foundation/piles up to 80' bgs.
3) Is groundwater known to be contaminated by ❑onsite ®offsite ❑both or ❑unknown
sources? Describe source(s):
Existing data indicates historical groundwater contamination from up -gradient gasoline station
and industrial sources.
4) What is the direction of groundwater flow at the Brownfields Property?
17
EMP Version 3, March 2023

Temporary monitoring wells were not surveyed and therefore a groundwater elevation map was
not developed for the site. Shallow groundwater may be inferred to follow surficial topography,
which is generally to the south-southeast at the site.
5) Will groundwater likely be encountered during planned redevelopment activities (e.g.
footer/utility construction or helical pilings?)
®Yes ❑No
If yes, describe these activities:
Groundwater may be encountered during deep foundation/pile work.
In the event that groundwater is encountered during redevelopment activities (even if no is
checked above), list activities for contingent management of groundwater (e.g., dewatering
of groundwater from excavations or foundations, containerizing, offsite disposal, discharge to
sanitary sewer, NPDES permit, or sampling procedures).
Excavations in areas where groundwater accumulated will be allowed to re -infiltrate for
approximately 24 hours (if it does not affect the construction schedule) or removed so that
construction may proceed. If groundwater must be removed, it will be pumped out via
vacuum trucks and taken off -site for disposal at a permitted facility.
In the event that significant groundwater dewatering is required, in lieu of offsite disposal, we
would consider collection, pretreatment and discharge to the City of Raleigh POTW under a
temporary Industrial User Permit.
6) Are monitoring wells currently present on the Brownfields Property? ................. ❑Yes ®No
If yes, are any monitoring wells routinely monitored through DEQ or other
agencies?.................................................................................................................. ❑Yes ®No
7) Please check methods to be utilized in the management of known and previously
unidentified wells.
❑ Abandonment of site monitoring wells in accordance with all applicable regulations. It
is the Brownfields Redevelopment Section's intent to allow proper abandonment of
well(s) as specified in the Brownfields Agreement, except if required for active
monitoring through another section of DEQ or the EPA.
❑ Location of existing monitoring wells marked
❑ Existing monitoring wells protected from disturbance
® Newly identified monitoring wells will be marked and protected from further
disturbance until notification to DEQ Brownfields can be made and approval for
abandonment is given.
8) Please provide additional details as needed:

Contractors engaged in ground disturbing activities, including excavation, foundation
construction and grading, will comply with the applicable provisions of Occupational
Health and Safety Administration (OSHA) regulations, as well as all other applicable federal, State
of North Carolina and local safety regulations. To comply with OSHA requirements for protection
of their work force, contractors and their safety managers will review site conditions, conduct a
workplace exposure assessment and plan for OSHA compliance and worker protection and
training. Control measures, among others, can include limiting disturbed area, temporarily
covering exposed soils if areas not ready for final backfill, the use of personal protective
equipment, mitigation measures such as venting, and limiting worker entry into trenches and
other subsurface work areas as much as is feasible.

Brownfields Redevelopment Section's Vapor Intrusion Mitigation System Design Submittal
Requirements.
Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land
use restrictions or requirements of the recorded or draft Brownfields Agreement and that
separate approval of mitigation measures will be required.
CONTINGENCY PLAN
In this section, please provide actions that will be taken to identify or manage unknown
potential new sources of contamination. During redevelopment activities, it is not uncommon
that unknown tanks, drums, fuel lines, landfills, orother waste materials are encountered.
Notification to DEQ Brownfields project manager, UST Section, Fire Department, and/or other
officials, as necessary and appropriate, is required when new potential source(s) of
contamination are discovered. These Notification Requirements were outlined on Page 1 of this
EMP.
Should potentially impacted materials be identified that are inconsistent with known site
impacts, the DEQ Brownfields project manager will be notified, and a sampling plan will be
prepared based on the EMP requirements and site -specific factors. Samples will generally be
collected to document the location of the potential impacts.
Check the following chemical analysis that are to be conducted on newly identified releases:
® Minimum Sample Requirements: Volatile organic compounds (VOCs) by EPA Method 8260;
Semi -volatile organic compounds (SVOCs) by EPA Method 8270; and_Metals RCRA List +
Hexavalent Chromium by EPA Method 6020/7199
❑ Pesticides: Specify Analytical Method Number(s):
Click or tap here to enter text
21
EMP Version 3, March 2023

❑ PCBs: Specify Analytical Method Number(s):
® Other Constituents & Analytical Method(s) (e.g. Herbicides)
Please note, if field observations indicate the need for additional analyses, they should
be conducted, even if not listed here.
Hexavalent Chromium via EPA Method 7199 will be run on the soil sample with the
highest total chromium laboratory result. In the case of soil stockpiles, if the
hexavalent chromium analysis of that sample is below the hexavalent chromium PSRG,
then the soil in the stockpile is considered to be below the hexavalent chromium PSRG.
Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
There is a possibility, albeit small, that materials of unknown type (tanks, drums or impacted soils)
could be present on the site. The worker and contractor must be able to recognize when conditions
change at the site. Field staff must be able to determine if a new discovery of changed chemical
conditions has occurred, and if so, if it is significant. If there is question of the significance of a new
discovery or changed condition, the environmental manager (Terracon) or equivalent qualified
environmental professional should make the determination. The worker or contractor should be alert
during earthwork for the following indications that will trigger the possible identification of a new
condition not addressed by previous investigations and evaluation.
Underground Storage Tanks — Note that UST Section guidelines must be followed for sample
frequency during UST closure. Unless damage to onsite structures to remain as part of
redevelopment would occur, USTs shall be removed from the Brownfields Property:
Prior assessment reports have not identified suspected underground storage tanks (USTs)
remaining at the site. The worker and contractor should be cognizant of man-made containers or
remnants of containers of any material. The presence of whole or crushed drums or containers
in excess of one gallon in the soils in combination with odor or unique color changes may be
indicative of a changed condition. Should USTs, drums, or similar items be encountered during
redevelopment activities, the environmental manager (Terracon) should be contacted
immediately, and the identified item should be left as encountered. The NC Brownfields project
manager will be notified by site's environmental manager. Following notification of the NC
Brownfields project manager, the UST will be rendered inert of potential combustible vapors and
removed from the ground. The UST will be taken offsite for proper disposal and soil samples will
be collected from the UST basin and four sidewalls, along any associated piping, and analyzed for
VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D), and RCRA 8 Metals (EPA Methods
6010D and 7471B). Documentation of the UST removal activities, UST disposal, and sampling
results will be provided to the NC Brownfields project manager upon receipt by the
environmental manager.
Sub -Grade Feature/Pit:
If during redevelopment activities, an unknown sub -grade feature/pit is encountered, the
environmental manager (Terracon) should be notified immediately. The environmental manager
will supervise exploratory excavation in and around the feature and soils will be screened for
potential impacts. If potential impacts are identified, the NC Brownfields project manager will be
22
EMP Version 3, March 2023

notified and soil samples will be collected from the area of potential impacts and analyzed for
VOCs (EPA Method 826013), SVOCs (EPA Method 8270D), and RCRA 8 Metals (EPA Methods
6010D and 747113). The location of the feature will be recorded for future reference. Soil
sampling results will be provided to the NC Brownfields project manager.
Buried Waste Material — Note that if buried waste, non-native fill, or any obviously filled materials
is encountered, the DEQ Brownfields Redevelopment Section must be notified to determine if
investigation of landfill gases is required:
If during redevelopment activities, buried waste material is encountered, the environmental
manager (Terracon) should be notified immediately, and the identified waste should be left as
encountered. The NC Brownfields project manager will be notified by site's environmental
manager. Following notification of the NC Brownfields project manager. The environmental
manager will supervise exploratory excavation in and around the waste and soils will be
screened for potential impacts. The waste should be segregated from surrounding soils,
inventoried and taken offsite for proper disposal. If potential impacts are identified, the NC
Brownfields project manager will be notified and soil samples will be collected from the area of
potential impacts and analyzed for VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D),
and RCRA 8 Metals (EPA Methods 6010D and 7471B). The location of the feature will be
recorded for future reference. Documentation of the waste removal activities, waste disposal,
and sampling results will be provided to the NC Brownfields project manager upon receipt by
the environmental manager.
Re -Use of Impacted Soils Onsite:
See Part 1— Soil and Part LA — Managing On -site Soil for details regarding the re -use of impacted
soil on -site.
If unknown, impacted soil is identified onsite, management onsite can be considered after the
project team provides the necessary information, outlined in Part LA. Item 11, for Brownfields
project manager approval prior to final placement onsite.
If other potential contingency plans are pertinent, please provide other details or scenarios as
needed below:
If impacted soil is noted at the site, the suspect soils should be isolated as soon as possible from
contact and disturbance by rain and wind until screening identification can be made.
Construction flagging tape attached to stakes can be used to prevent accidental movement of the
soils by earthwork operations. Covering of the soils with plastic sheeting and weight the covering
with planks, sandbags, or equivalent should occur. The soils should be screened for volatile and
semi -volatile organic compounds using a photoionization detector (PID). The screening will be
conducted by the on -site environmental manager or other qualified environmental professional.
The owner or contractor may alternatively go directly to laboratory testing for identification
purposes.
Screening tests can be conducted on the site and can produce preliminary results quickly. The
field test does not produce a precise measurement of the amounts of contaminants found in the
soils, but indicates whether contaminants are likely present and warrant further caution and
actual measurement. If preliminary screening activities indicate a changed condition may be
present, it may be necessary to conduct laboratory testing to determine if contaminants are
23
EMP Version 3, March 2023

present in the soil and actually pose a significant risk. Laboratory testing requires time that
varies depending on the type of test needed. In general, laboratory testing for RCRA 8 Metals,
VOCs, and SVOCs can take approximately 5 to 7 business days unless special arrangements are
made with the laboratory for more expensive "RUSH" results. During this time, the suspected
impacted soils should be further isolated from worker and public exposure. Special handling and
care must be taken in sampling and transporting soils for the laboratory tests to be accurate. The
workers in physical contact with suspect impacted soil should have training consistent with 29
OSHA 1910.120.
For small volumes, the soil can be placed temporarily in steel open -top drums with bolt -on lids.
After sealing, the drum should be clearly labeled with pertinent information such as "Do Not
Disturb", sample number, date, and name of sampler. The drums should be placed in an on -site
area protected from general traffic. For larger volumes, it can be effective to place the soils into
commercial roll -off dumpsters which have been previously washed and cleaned of residues or
soils can be stockpiled on plastic sheeting. The containers will not have free -draining bottoms and
stockpiles shall be graded, bermed, or provided with an equivalent barrier where necessary to
help prevent water run-off. The tops of the containers or stockpiles will then be covered with
plastic sheeting and secured against wind and rain. The commercial containers or stockpiles
should be placarded with information similar to the notation on drums.
POST -REDEVELOPMENT REPORTING
® Check this box to acknowledge that a Redevelopment Summary Report will be required for the
project. If the project duration is longer than one year, an annual update is required and will be
due by January 31 of each year, or 30 days after each one-year anniversary of the effective date of
this EMP (as agreed upon with the project manager). These reports will be required for as long as
physical redevelopment of the Brownfields Property continues, except that the final
Redevelopment Summary Report will be submitted within 90 days after completion of
redevelopment. Based on the estimated construction schedule, the first Redevelopment Summary
Report is anticipated to be submitted on 1/31/2024
