Ms. Eckard:
S&ME, Inc. (S&ME), on behalf of Novare Group, presents this revised Soil Management Plan to address potentially impacted soils, should they be encountered during
construction activities for the above referenced site properties. A Soil Management Plan
(Rev 3), dated May 12, 2014, was submitted and implemented for the site property
having the address of 631 N. Tryon Street (Mecklenburg parcel nos. 07803301 and 07803303). This revised Soil Management Plan is to amend the May 12, 2014 Site
Management Plan to include an additional, adjacent parcel having the address of 601 N.
Tryon Street (Mecklenburg parcel no. 07803302). S&ME understands that a Brownfields
Agreement (BFA) was finalized for the initial site property (parcel nos. 07803301 and
07803303), dated May 27, 2014 between the North Carolina Department of Environment and Natural Resources (NCDENR) and the property owner 10th & Tryon, LLC (and/or
developer – Skyhouse Charlotte, LLC). Further, S&ME understands that the developer is
also currently pursuing a BFA for the adjacent property (parcel no. 07803302).

Based on conversations and approvals with the NCDENR Brownfields, a Site Management Plan is required as part of the BFA for both properties. Therefore, the May
12, 2014 Site Management Plan (Rev 3) is being amended to include all three parcels.

Background
The three parcels total approximately 3 acres (2.173-acres for parcels 07803301/07803303 and approximately 0.86 acres for parcel 07803302) located in
Charlotte, North Carolina. The 2.173-acre parcel covers the northeastern portion, and the
0.86 acre parcel covers the remaining southwestern portion of the city block situated
between North Tryon Street, West 10th Street, North Church Street, and West 9th Street.

Below is a summary of the various documents as they pertain to the two site parcels.

Parcels 07803301 and 07803303 (631 North Tryon Street): Based on a review of the above documents, the larger site parcel contained a former
gasoline station and dry cleaner located in the southeast corner of Parcel no. 07803301,
near the intersection of West 10th Street and North Tryon Street. Soil sampling
conducted by Piedmont Geotechnical Consultants (PGC) in 2005 identified detectable concentrations of volatile organic compounds (VOCs) and polycyclic aromatic
hydrocarbons (PAHs) at one sample location (B-1), near the former gasoline station.
Although concentrations of select metals were also identified in the soil samples, the
concentrations are stated to be consistent with natural occurring concentrations and
therefore, not suspected to be an indication of a release. No groundwater samples were collected by PGC in 2005.

In 2007 and 2012, S&ME conducted 15 soil borings (nine in 2007 and six in 2012) and
based on the field observations, nine soil and three groundwater samples were submitted
for laboratory analysis. The soil samples submitted for analysis in 2007 were analyzed for VOCs, PAHs, volatile and extractable petroleum hydrocarbons (VPH/EPH), and total
lead and chromium. The soil samples submitted for analysis in 2012 were analyzed for
VOCs and PAHs. The groundwater sample collected in 2007 was analyzed for VOCs,
2
Soil Management Plan (Rev. 4) S&ME Project No. 4335-14-075 SkyHouse Phase I and Phase II Sites, Charlotte, North Carolina October 15, 2014
semi-volatile organic compounds (including PAHs), VPH, EPH, and total lead and
chromium. The groundwater sample collected in 2012 was analyzed for VOCs and PAHs. Results of laboratory analyses and field sampling results collected by S&ME during the two sampling events identified no evidence of a release. A Boring/Well
Location Map indicating the approximate former gasoline station/dry cleaner and
boring/well locations by PGC and S&ME is provided as Figure 3.
The BFA was finalized on May 27, 2014 and included the following Land Use Restrictions (LURs):
1. The Property can only be used for residential, parking, office and retail
purposes.
2. Groundwater may not be used for any purpose without the prior written approval from the NCDENR. 3. Soil disturbances must be handled in accordance with an approved Soil
Management Plan including subsequent NCDENR approved
modifications to the plan.
4. None of the contaminants known to be present in the environmental media at the Property may be used or stored at the Property, except in de minimis amounts for cleaning and other routine housekeeping activities.
5. The Property cannot be used as an outdoor park or for outdoor sports.
6. The Property may not be used as a playground or for child care centers or
pre-secondary schools. 7. The Property owner is responsible for repairs to monitoring wells on the Property.
8. NCDENR and/or others conducting NCDENR-directed environmental
assessment or remediation on the Property, cannot be denied access.
9. In January of each year, the Property owner is required to submit a Land Use Restriction Update (LURU) to NCDENR.
Note: The above listed restrictions are abbreviated from the BFA and are not
intended to be a complete list. Please refer to the BFA for full details.

Parcel 07803302 (601 North Tryon Street): Based on a review of the above referenced DRAFT Phase I Environmental Site
Assessment, the following recognized environmental conditions (RECs) were identified
associated with the smaller parcel:

• According to reviewed Sanborn fire insurance maps, a used auto sales facility with an auto body/repair area was present in the southern portion of the subject
property in 1963. Solvents and petroleum products may have been used at this
facility. The time frame of the operation of the auto body/repair facility was not
identified by standard historical sources.
• According to reviewed Sanborn fire insurance maps, multiple residences and apartments were located in the western portion of the subject property from at
least 1905 through 1963. The potential exists for these structures to have used
heating oil tanks.

Soil Management Plan (Rev. 4) S&ME Project No. 4335-14-075 SkyHouse Phase I and Phase II Sites, Charlotte, North Carolina October 15, 2014
In accordance with LUR number 3 of the BFA for parcel nos. 07803301 and 07803303,
and as stated above, S&ME prepared a Soil Management Plan (Rev 3) to address the soil disturbances. The Soil Management Plan (Rev 3) addressed assessing soils following excavation but prior to the soils being transported off-site. However, due to the amount
of soils that are anticipated to be removed and transported off-site from the smaller parcel
(Parcel no. 07803302), and based on a conversation with Ms. Sharon Eckard of the
NCDENR on July 30, 3014, the Soil Management Plan (Rev 3) has been amended to also allow for the in-place assessment of soils that are anticipated to be excavated and transported off-site. The following sections address the various assessment options.

Assessment and Management of Excavated Site Soils
Site soils that are excavated for site redevelopment and are to be removed from the site are to be evaluated during excavation activities to assess for potential impacts. The soils are to be evaluated for evidence of impacts by an environmental professional and
segregated as to potential impacted and apparent non-impacted soils. All soils are to be
field screened by an environmental professional for evidence of staining, noting
detectable petroleum or chemical odors and, collecting a “grab” sample for relative organic vapor levels using an organic vapor analyzer (OVA). The “grab” sample is to be placed into a sealable plastic (e.g., Ziplock®) bag, allow time for the accumulation of
organic vapors to collect in the “headspace” of the bag and insert the tip of an OVA, and
record the relative organic vapor measurements.
Soils with apparent evidence of impacts based on the field screening are to be placed into one stockpile and soils with no apparent evidence of impacts are to be segregated into a
separate stockpile. The soils of the two stockpiles are to be placed onto, and covered by,
a non-porous, waterproof material such as plastic sheeting and secured to reduce the
potential for exposure and runoff during rain events, pending laboratory analyses.
Stockpile of Apparent Non-Impacted Soil

• In order to further evaluate the stockpiled soils containing no apparent evidence of
impacts, one composite sample is to be collected for approximately every 200 tons of soil and submitted to a North Carolina certified laboratory for chemical
analysis. Based on the analyses previously conducted of site soils during the
various assessment activities, the soil sample(s) should be analyzed for VOCs
using EPA Method 8260/5035 and PAHs using EPA Method 8270.
• Should no target constituent be detected in the soil sample(s) above the lowest of the NCDENR Inactive Hazardous Site Branch (IHSB), Residential Preliminary
Soil Remedial Goals (PSRGs), the soils can be transported off-site for disposal,
used as off-site beneficial fill material with documentation of acceptance by the
receiving party, or used onsite as beneficial fill material provided that the soil also would not be considered a hazardous waste. Should target constituents be detected
in site soil sample(s) in excess of Residential PSRGs but below Industrial PSRGs,
these soils could be managed onsite under the following conditions: the soil shall
be moved to a location which will be covered with asphalt and/or concrete, with
its location and depth documented, and the soil covered with a geotextile fabric
4

and clean fill so that its location can be identified if encountered in the future, and
its location will be provided to NCDENR in an updated survey plat. Should target constituents be detected in the soil sample(s) above NCDENR IHSB Industrial PRGs, the soils are to be considered as a waste and are to be properly
managed as stated below for the “impacted” soil stockpile.”

Stockpile of Suspected Impacted Soil
• In order to further evaluate the stockpiled soils suspected as containing impacts,
one composite sample is to be collected of soil for approximately every 500 tons,
or as required by the receiving permitted facility, and submitted to a North
Carolina certified laboratory for chemical analysis. Based on the analyses previously conducted of site soils during the various assessment activities, the soil
sample(s) should be analyzed for VOCs using EPA Method 8260/5035 and PAHs
using EPA Method 8270.
• Should no target constituent be detected in the soil sample(s) above the Residential PSRGs, the soils can be handled in according to the parameters
provided in the 2nd bullet above.
• Should any target constituent be detected in the soil sample(s) at levels above the
NCDENR IHSB Industrial PSRGs, or are not needed as beneficial fill material onsite or offsite, the soils are to be considered a waste and must be properly
managed. The actual handling of the waste will be based on the type and
concentrations of the constituents detected, the NCDENR guidance, and the
Brownfields Agreement. NOTE: additional analysis may be necessary for
acceptance by the permitted disposal/treatment facility, if off-site disposal/treatment of the waste is required.

In-Place Assessment and Management of Site Soils
In order to eliminate the stockpiling of and the sampling and analysis of stockpiled soils,
and to expedite the removal of soils from the site prior to transport off-site for disposal, soils in areas proposed to be removed may be assessed in-place. The in-place assessment
shall consist of the collection of soil samples for laboratory analysis that are
representative of the soil to be excavated and transported off-site for disposal. The in-
place assessment shall consist of:

• Conducting soil borings that extend from current ground surface to the proposed
excavation depth/elevation with one soil sample per boring submitted for
laboratory analysis of VOCs using EPA Method 8260/5035 and PAHs using EPA
Method 8270. During each boring, soils will be collected continuously from the surface to the termination depth and evaluated in the field as to evidence of potential impacts (i.e., staining, odors, and volatile organic vapor readings, etc.).
The discrete depth interval that exhibits the most apparent evidence of impacts
will be submitted for laboratory analysis. Should no evidence of apparent impacts
be observed, then the sample will be collected at varying depths across the assessment area.

Soil Management Plan (Rev. 4) S&ME Project No. 4335-14-075 SkyHouse Phase I and Phase II Sites, Charlotte, North Carolina October 15, 2014
• The soil borings will be conducted at a rate of one boring per every approximate
2,500 square feet (ft2) or 50 feet by 50 feet area in areas of the site where no identified environmental concerns were identified according to information within
the above referenced reports.
• In areas of environmental concern and the identified RECs, the frequency of
borings will increase to one boring per every approximate 1,000 ft2 or approximately every 30 feet by 30 feet area with a corresponding increase in soil
samples for laboratory analysis.
• The results of the laboratory analysis of each soil sample will be compared to the
above referenced PSRGs.
• Should no target constituent be detected in the soil sample(s) above the lowest of
the Residential PSRGs, the soils within the corresponding 50 feet by 50 feet area
can be transported off-site for disposal, used as off-site beneficial fill material
with documentation of acceptance by the receiving party, or used onsite as beneficial fill material provided that the soil also would not be considered a hazardous waste.
• Should target constituents be detected in the soil sample(s) above the lowest of
the Residential PSRGs, the soil can either be excavated, stockpiled, resampled and managed in accordance with above Stockpile of Suspected Impacted Soils, or the soils can be excavated, direct loaded and transported off-site for disposal as
waste.

Off-site Disposal Options Based on the previous soil sampling results, the generation of hazardous waste is not anticipated. However, if any future soil samples results suggest otherwise, additional soil
sampling would be necessary to classify the waste followed by appropriate handling and
disposal. Below is a partial list of typical disposal/treatment facilities for non-hazardous
waste that may accept the soils; however, additional facilities may be available.

At completion of site soil removal activities, documentation of all soils (non-impacted
and impacted) leaving the site are to be provided to the NCDENR, Brownfields. The documentation is to include laboratory results of sample analysis, volumes (or tonnage) of soils transported off-site, disposal location, and disposal location site use.

Underground Storage Tanks
Based on previous site information and assessment activities, no underground storage tanks (USTs) are known or suspected to exist at the site; however, should UST(s) or appurtenances that appear to be related to an UST (e.g., vent piping, fill piping, dispenser
piping, fill ports, etc.) be encountered during site redevelopment activities, they will be
closed in accordance with the current NCDENR, UST Section guidance, or as approved
by the NCDENR, Brownfields Section. Imported Fill It is expected that approximately 1,600 cubic yards of fill soil will be brought to the site for use as
imported fill. One composite sample of soil will be obtained from each fill source prior to bringing the soil to the site. The composite soil sample(s) will be analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and the Hazardous Substance List metals. Fill soil
will be considered suitable for placement at the site if it does not contain compound concentrations above NCDENR IHSB Residential PSRGs and typical background levels for
metals.
Final Grade Sampling In any area where the ground surface is not to be covered by building foundations, sidewalks, or
asphaltic or concrete parking areas and driveways, and where ground contact by humans and
animals may occur, representative final grade soil sampling shall be performed to the written satisfaction of DENR, including analysis for VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, and Hazardous Substance list metals.
Reporting
Within 90 days after physical redevelopment of the property is completed, a report will be submitted to DENR and subject to its approval, summarizing environmentally-related activities including, but not limited to, 1) actions taken pursuant to the Property’s Brownfields Agreement,
2) soil grading and cut and fill actions, 3) field screening, sampling and laboratory analysis of environmental media, 4) stockpiling, containerizing, decontaminating, treating, handling, laboratory analysis and ultimate disposition of any soil, groundwater, or other materials suspected
or confirmed to be contaminated with regulated substances, and 5) the removal of any contaminated soil, water or other contaminated materials (for example, concrete, demolition
debris) from the Property, including copies of all legally required manifests.
Exclusions This soil management plan addresses the sampling and analysis, and the disposal of soils
to be removed from the site during construction activities. This plan excludes, but these
exclusions are not limited to the following:

• Sampling of non-excavated soils;
• Health and Safety procedures protocols during construction or soil handling;
• Additional soil or groundwater assessment of site;
