NORTH CAROLINA BROWNFIELDS PROGRAM
ENVIRONMENTAL MANAGEMENT PLAN
This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Program at the direction of a Brownfields project manager.
The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during the 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 resultant EMP to be valid for use, it
must be completed, reviewed by the program, 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 completed 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.
Voluntary Metrics Tab
The NC Brownfields Program 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: NA
2. Estimated jobs created:
a. Construction Jobs: NA
b. Full Time Post-Redevelopment Jobs: NA

1) Known or suspected contaminants in soil (list general groups of contaminants):
According to the Hart Hickman 2008 Phase 2 report, VOCs and PAHs did not exceed DEQ
screening levels in collected soils samples. Chromium was detected above the EPA Soil
Screening Levels but within naturally occurring Chromium background levels. Work from
the proposed project would be conducted in an “area of potential soil contamination” as
denoted on the plat map. However, exposure to VOCs, PAHs, or other soil contamination
is considered minimal due to the shallow nature of the proposed excavation.

EMP Version 2, January 2021
2) Depth of known or suspected contaminants (feet):
Based on Hart Hickman and Terracons Annual Groundwater Monitoring Report field notes,
historical groundwater levels range between 22-14 feet Below Ground Surface, total well depth is
30 feet bgs. Chlorinated solvents were detected in groundwater samples above the 2L standards
and residential and nonresidential groundwater screening levels in MW-1.
3) Area of soil disturbed by redevelopment (square feet):
Approximately 10 square feet.
4) Depths of soil to be excavated (feet):
Approximately 4-5 feet below ground surface.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
9.08 cubic yards
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
The total amount of soil to be excavated is expected to be minimal, the excavated soil will be used
as backfill for the foundation of the replacement poles.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
The total amount of soil to be excavated is expected to be minimal, the excavated soil will be used
as backfill within the foundation of replacement poles. Remaining soil will be raked to the level of
the existing grade and seeded and strawed.
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
☒ Yes, describe the method will include:
Two approaches to dust control will be utilized on the proposed project: proactive work
strategies to minimize fugitive dust generation and reactive engineered controls to mitigate
dust generation and/or capture fugitive dust. Because a variety of activities have the
potential to generate fugitive dust at a given site, there is no unique response to dust
prevention and control. Proactive measures would consist of the utilization of plastic
sheeting to cover excavated soils (spoil) from mobilization during wet weather events,
sediment socks or filter fabric surrounding spoil piles and stormwater inlet filters to prevent
mobilized sediment from entering storm drains. The immediate seed and strawing of the
excavated areas. Reactive controls would be vacuum trucks to remove any mobilized
sediments. As the volume of soil to be excavated is less than 10 cubic yards, fugitive dust is
not anticipated. Should an issue arise, contractors contact the project environmental
professional. If the project environmental professional confirms that fugitive dust has
become an issue, the DEQ Brownfields project manager will be contacted within 48 hours to
advise of the condition.
☐ No, explain rationale:
Click or tap here to enter text.
Field Screening of site soil
The total amount of soil to be excavated is expected to be minimal, the excavated soil will be used as
backfill within the foundation of replacement poles. Remaining soil will be raked to the level of the
existing grade and seeded and strawed.
11
EMP Version 2, January 2021
☒ Yes, describe the field screening method, frequency of field screening, person conducting
field screening:
During soil disturbance at the proposed pole locations, workers or contractors will observe
the soils for evidence of potential impacts. Soils excavated from the proposed pole
foundations will be screened at two (2’) foot intervals. Soils from each boring will be placed
into two separate sealed plastic bags. The soils in one bag will be allowed to volatilize for
approximately five (5) minutes prior to screening for volatile vapors, while the second bag
is immediately placed on ice to prevent volatilization until collection of the sample for
submittal to the laboratory. Headspace screening of soil samples will be conducted utilizing
a calibrated photoionization detector (PID) equipped with a 11.7 electron-volt (eV)
ultraviolet lamp source, which provides measurements of total volatile organic vapors in
parts per million (ppm) isobutylene equivalents. Sampling personnel will wear disposable
nitrile gloves to minimize the potential for sample contamination. Soils will be evaluated
for the presence of odor, staining, and elevated photoionization detector (PID) readings.
An aliquot with the highest PID reading will be collected for analysis. Sampling equipment
will be decontaminated using a phosphate‐free soap and distilled water solution prior to
and between the collection of each sample. Should the contractors observe soil staining,
odors, or other concerns, they will contact the project environmental professional. If the
project environmental professional confirms that the excavated soils maybe impacted, the
DEQ Brownfields project manager will be contacted within 48 hours to advise of the
condition.
☐ No, explain rationale:
Soil Sample Collection
☒ Yes, describe the sampling method (e.g., in‐situ grab, composite, stockpile, etc.):
Soils excavated from the proposed pole foundations will be screened at two (2’) foot
intervals. Soils from each boring will be placed into two separate sealed plastic bags. The
soils in one bag will be allowed to volatilize for approximately five (5) minutes prior to
screening for volatile vapors, while the second bag is immediately placed on ice to prevent
volatilization until collection of the sample for submittal to the laboratory. Headspace
screening of soil samples will be conducted utilizing a calibrated photoionization detector
(PID) equipped with a 11.7 electron-volt (eV) ultraviolet lamp source, which provides
measurements of total volatile organic vapors in parts per million (ppm) isobutylene
equivalents. Sampling personnel will wear disposable nitrile gloves to minimize the
potential for sample contamination. Soils will be evaluated for the presence of odor,
staining, and elevated photoionization detector (PID) readings. An aliquot with the highest
PID reading will be collected for the below listed analysis.

use restrictions or requirements of the recorded or draft Brownfields Agreement and that
separate approval of mitigation measures will be required.
CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials
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, or other 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:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and
silver)

Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
21
EMP Version 2, January 2021
Click or tap here to enter text.
Underground Storage Tanks:
UST sampling would be consistent with that of NC DEQ UST sampling regulations.
Sub-Grade Feature/Pit:
Soil characterization sampling would be conducted in the event of visual or olfactory observations,
as well as additional geophysical assessment to delineate the subgrade/pit feature.
Buried Waste Material – Note that if buried waste, non-native fill, or any obviously filled materials
is encountered, the DEQ Brownfields Program must be notified to determine if investigation of
landfill gases is required:
In the event that buried material is encountered, Pike would stop work and contact the sites
Brownfields manager.
Re-Use of Impacted Soils On-Site:
Impacted soils are not expected given the shallow nature of the excavation, excavated soils will be
returned to the excavation during pole installation or spread on site and leveled with the existing
grade.
If unknown, impacted soil is identified on-site, management on-site can be considered after the
project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields
Project Manager approval prior to final placement on-site.
If other potential contingency plans are pertinent, please provide other details or scenarios as
needed below:
