EMP Version 2, June 2018   
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   

So that the EMP provides value in protecting brownfields eligibility and public health, the 
preparer shall ensure that the following steps have been completed prior to submitting the 
EMP for review.  Any EMP prepared without completing these steps is premature.   

☒ Site sampling and assessment that meets Brownfields’ objectives is complete and has 
been reviewed and approved by the Brownfields Project Manager. 

☒ Specific redevelopment plans, even if conceptual, have been developed for the project, 
submitted and reviewed by the Brownfields Project Manager.

1) Known or suspected contaminants in soil (list general groups of contaminants): 
Tabular summaries of available soil sample analytical data in comparison to the North Carolina 
Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary 
Soil Remediation Goals (PSRGs) and DEQ Underground Storage Tank (UST) Section Action Levels 
(where applicable) are included as Table 1A and Table 1B.  A soil sample location map is provided 
as Figure 3A, an in situ soil sample location map is provided as Figure 3B, and a soil sample 
compounds concentration map is provided as Figure 3C.  A brief summary of the soil assessment 
results is provided below. 

7 
EMP Version 2, June 2018   
Volatile Organic Compounds (VOCs) 
Laboratory analytical results indicate that low levels of several petroleum‐related compounds 
were detected at concentrations above the laboratory method detection limits, but below the 
DEQ IHSB PSRGs in an area of surficial staining in the northeastern portion of the Site.  In 
addition, a trace level of 1,4‐dichlorobenzene (0.0025 mg/kg) was detected at a concentration 
above the laboratory method detection limit, but below DEQ IHSB PSRGs in a soil sample (SB‐4) 
collected beneath the slab of the dye house in the western portion of the Site.  Aside from trace 
levels of acetone, no other VOCs detected above laboratory method detection limits in soil 
samples collected at the Site.   

Semi‐Volatile Organic Compounds (SVOCs) 
As shown in Table 1B and in Figure 3C, laboratory analytical results indicate that low levels of 
benzo(a)pyrene (up to 0.22 J mg/kg) were detected at concentrations above the DEQ IHSB 
Residential PSRG in in situ soil characterization soil samples EX‐18 and EX‐23.  No other SVOCs 
were detected at concentrations above the PSRGs in soil samples collected at the Site. 

Total Petroleum Hydrocarbons (TPH) 
As shown in Table 1A and in Figure 3C, TPH as diesel range organics (480 mg/kg) was detected at 
a concentration above the DEQ UST Section Action Level of 100 mg/kg in soil sample SS‐5 
collected in an area of surficial staining located in the northeastern portion of the Site.  TPH 
fractions were not detected above the laboratory method detection limits in other soil samples 
collected at the Site. 

Metals  
As expected, several metals have been detected at concentrations above the laboratory method 
detection limits in soil samples collected at the Site.  The detected metals concentrations appear 
to be consistent with naturally occurring levels in Site area soil and are considered to represent 
background concentrations. 

2) Depth of known or suspected contaminants (feet): 
Soil samples containing benzo(a)pyrene at concentrations exceeding the Residential PSRG were 
collected from depths ranging from 0 to 3 feet below grade. It is estimated that diesel impacted 
soil is limited to shallow soil (less than 2 ft bgs) in an approximate 650 sq ft area in the 
northeastern portion of the Site.  The locations at the Site with compound concentrations above 
the applicable screening criteria are shown in Figure 3C. 

3) Area of soil disturbed by redevelopment (square feet): 
Grading will generally be conducted across the entire Site prior to construction (approximately 
186,500 sq ft). 

4) Depths of soil to be excavated (feet): 
Cut depths in the western portion of the Site will extend to depths ranging from less than 1 ft to 
approximately 8.5 ft.  

8 
EMP Version 2, June 2018   

5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): 
A copy of the most recent version of the cut‐fill analysis is provided as Appendix B.  Grading and 
construction activities for the proposed redevelopment at the Site will generate approximately 
8,000 cubic yards of soil that will likely need to be transported off‐Site to achieve proposed final 
grade elevations. The export soil volume includes approximately 5,600 cubic yards of 
geotechnically unsuitable undocumented urban fill that has been identified at varying depths 
across the Site. 

Grading activities will be conducted in accordance with a grading plan utilizing grading 
equipment (i.e. backhoes, front end loaders, bull dozers, etc.) and the Site development 
contractor will implement best management practices in accordance with a sediment and 
erosion control plan (i.e. implementation of silt fencing, berming, and covering stockpiled soil 
with plastic) to manage soil on‐Site during Site redevelopment activities and to prevent 
redistribution of soils onto adjacent properties.  Grading and redevelopment activities will be 
conducted in general accordance with applicable local, state, and federal regulations. 

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:             
Soil samples collected from in‐situ soil characterization sections EX‐18 and EX‐23 contained low 
levels of benzo(a)pyrene at concentrations exceeding the Residential PSRGs. These sections 
comprise a total of approximately 850 cubic yards of soil which are generally composed of urban 
fill unsuitable for construction purposes and are therefore planned for excavation.  

TPH as diesel range organics at a concentration above the DEQ UST Action Level are estimated to 
be in shallow soil (less than 2 ft bgs) in an approximate 650 sq ft area in the northeastern portion 
of the Site (Figure 3C).  However, this area is proposed for fill during redevelopment activities 
and no cut is this area is currently planned. 

7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:   
Shallow soil unsuitable for construction purposes generated during grading activities in the areas 
of EX‐18 and EX‐23 (total of approximately 850 cubic yards) will be exported off‐Site to a suitable 
location with DEQ prior approval. 

Part 1.A. MANAGING ONSITE SOIL 
If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields 
Property, or otherwise disturbed during site grading or other redevelopment activities, please

DEQ Brownfields database to demonstrate material from these facilities is suitable for use as 
structural fill at a Brownfields property. 

If fill soil is obtained from an off‐Site property that is not a known permitted quarry, a sampling 
plan will be developed and submitted for DEQ review.  DEQ approval of the sampling plan and 
analytical results will be obtained prior to transporting import soil to the Site.   

The specific sampling rate will be outlined in the aforementioned sampling plan.  However, if the 
proposed borrow source has not been previously developed (i.e., virgin land), soil samples will be 
collected for the laboratory analytical suite indicated above at a general rate of one per 1,000 
cubic yards.  If the borrow source property has been previously developed, soil samples will be

be excavated on site, related sampling results, etc. Provide a site map with locations of 
export and sampling results included. 
As noted above, grading for the proposed redevelopment at the Site will generate approximately 
8,000 cubic yards of soil that will likely need to be transported off‐Site to achieve proposed final 
grade elevations. Grading plans for the redevelopment generally include cut in western portions 
of the property and fill in eastern portions of the property. However, results of geotechnical 
assessment activities identified undocumented urban fill unsuitable for construction purposes at 
varying depths in several areas (including fill areas in the eastern portion of the Site) that will 
likely need to be exported from the Site. The anticipated export soil volume (8,000 cubic yards) 
includes approximately 5,600 cubic yards of geotechnically unsuitable undocumented urban fill. 
Cut depths on the western portion of the Site will extend to depths up to approximately 8.5 ft.  
Results of recently completed in situ soil characterization assessment activities indicate that 
composite soil samples collected from in‐situ soil characterization sections EX‐18 (0 to 3 ft below 
grade) and EX‐23 (0 to 2 ft below grade) contained concentrations of benzo(a)pyrene above the 
Residential PSRG.  Soil in remaining areas of proposed export at the Site do not contain 
compounds at concentrations above the PSRGs or naturally occurring levels in the case of metals.

Solid Waste approval prior to exporting soil to a non‐Brownfields property or non‐permitted 
disposal facility. 

Part 1.D. MANAGEMENT OF UTILITY TRENCHES 

☐ Install liner between native impacted soils and base of utility trench before filling with clean fill 
(Preferred) 

☒ 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: 
Click or tap here to enter text. 

☒ If no, include rationale here: 
Results of vapor intrusion assessment activities and recently completed supplemental vapor 
intrusion assessment activities indicate that potential vapor intrusion concerns are limited to the 
western portion of the Site.  A vapor intrusion mitigation plan is proposed for buildings that will 
be constructed in the western portion of the Site.  Proposed utility trenches will be beneath the 
vapor intrusion mitigation system and no additional barrier will be needed to further minimize 
vapor transport through the utility trench. 

Other comments regarding managing impacted soil in utility trenches:  
The contractor and workers will observe soil for potential impacts during utility installation activities. 
Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or filled 
or previously disposed materials of concerns (i.e., chemicals, tanks, drums, etc.).  Should the above be 

18 
EMP Version 2, June 2018   
noted during utility work, the contractor will contact the project environmental engineer to observe 
the suspect condition.  If the project environmental engineer confirms that the material may be 
impacted, then the procedures outlined in Managing On‐Site Soil above will be implemented.  In 
addition, the environmental engineer will contact the DEQ Brownfields project manager within two 
business days to advise that person of the condition. 

Should impacted soil be discovered during utility trenching activities, appropriate safety screening will 
be performed to protect workers during utility installation activities.  Safety screening activities 
include monitoring the worker breathing zone with a calibrated photoionization detector or similar 
instrument at all times when in utility trenches.  If safety screening results indicate further action is 
warranted, the work zone will be evacuated until appropriate engineering controls (such as use of 
industrial fans) are implemented. 

PART 2. GROUNDWATER – Please fill out the information below.

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.

Please provide details on the proposed methods of managing the following commonly 
encountered issues during redevelopment of Brownfields Properties. 
During construction activities, contractors may encounter unknown sub‐surface environmental 
conditions (i.e., tanks, drums, or waste materials) that if encountered, will require proper 
management.  Prior to beginning Site work, H&H will attend a pre‐construction kick‐off meeting 
with the PD and the redevelopment contractors to discuss the DEQ approved EMP and various 
scenarios when it would be appropriate and necessary to notify H&H of the discovery of unknown 
subsurface features or potentially impacted media at the Site. 

In the event that such conditions are encountered during redevelopment activities, the 

24 
EMP Version 2, June 2018   
environmental actions noted below will be used to assist in appropriate management of sub‐surface 
environmental conditions and determination of the most suitable final disposition of potentially 
impacted Site media. 

Underground Storage Tanks:  
In the event that an unknown UST or impacts associated with a UST release are discovered at the 
Site during redevelopment activities, the UST and/or UST related impacts will be addressed through 
the Brownfields Program.  DEQ Brownfields will be notified within 48‐hours of discovery of the UST. 

If an unknown UST is encountered, the UST will be removed, if possible, and transported off‐Site for 
disposal at a suitable facility.  Prior to removing the UST from the ground, residual fluids, if any, will 
be sampled for VOCs, SVOCs, and RCRA metals as needed for disposal purposes.  If a UST is 
encountered that cannot be removed, it may be abandoned in‐place with prior DEQ approval and 
construction will proceed.  Where appropriate, the bottom of the UST may be penetrated before 
abandonment to prevent fluid accumulation.  Impacted soil in the vicinity of the UST will be 
managed in accordance with the Managing On‐Site Soil section outlined in this EMP. 

Sub‐Grade Feature/Pit: 
If a sub‐grade feature or pit is encountered, it will be removed and transported off‐Site for disposal 
at a suitable facility.  If it cannot be removed, it will be filled with soil or suitable fill. Where 
appropriate, the bottom of the sub‐grade feature or pit may be penetrated before back filling to 
prevent fluid accumulation.  If the pit has waste in it, the waste may be set aside in a secure area 
and will be sampled for waste disposal purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and 
disposed off‐Site at a permitted facility or the waste will be managed in accordance with the 
Managing On‐Site Soil section outlined above in the EMP, whichever is most applicable based on 
the type of waste present.  If the observed waste characteristics indicate the concrete may 
potentially be contaminated to a significant degree, the concrete will be sampled and analyzed by 
methods specified by the disposal facility. 

Buried Waste Material: 
If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to 
stop work in that location and notify the project environmental engineer.  The environmental 
engineer will observe the suspect materials and collect samples for laboratory analysis, if 
warranted.  Confirmation sampling will be conducted at representative locations in the base and the 
sidewalls of the excavation after the waste or significantly impacted soil is removed.  The 
confirmation samples will be analyzed for VOCs, SVOCs, and RCRA metals (or other analyses as 
appropriate based on the type of waste material).  Information will be provided to DEQ Brownfields 
regarding the permitted facility used for disposal of the waste or significantly impacted soil. Areas of 
suspected contaminated soil that remain at the Site after excavation is complete above the DEQ 
IHSB Residential PSRGs will be managed pursuant to this plan.
