Dear Ms.Minnich:
On behalf of Tryon Investors, LLC,Wood Environment & Infrastructure Solutions, Inc. (Wood) is pleased to
submit this letter requesting additional approval to transfer soil resulting from grading and utility
trenching and future tree planting activities at the subject property. Wood has provided on-going
Brownfields consulting services at the subject property consisting of one parcel (Tax Parcel 073-073-01)
encompassing approximately 4.9 acres situated at the intersection of South Tryon Street and West Carson
Boulevard. The Prospective Developer’s (PD)General Contractor (GC) provided estimated quantities
regarding excavated soil that is presently stockpiled at the site or will soon be excavated and stockpiled
there.The GC provides Wood and the PD with photographic documentation of the soil stockpiles and the
location at the site from which the soil was excavated.
In response to Wood’s email Soil Transfer Request (dated May 7, 2020) The North Carolina Department of
Environmental Quality (NCDEQ), Division of Waste Management (DWM), Brownfields Program (BFP)
issued a letter (dated May 14,2020)approving transfer of soil from the subject property to the Woodlawn
Green Brownfield Properties (BF# 22023-18-060). This approval applied to transfer of approximately 2,500
cubic yards (CY) of soil.The soil transfer to Woodlawn Green was initiated on May 18, 2020. Subsequently,
based on Wood’s Letter Report of Stockpiled Soil Characterization, dated July 13, 2020, the NCDEQ, DWM,
BFP issued a letter (dated July 24,2020) approving transfer of approximately 3,000 cubic yards (CY)of soil
stockpiled from the subject property to the Matheson Avenue II Brownfield Property (BF# 22042-18-060)
and Matheson Avenue Creek (BF#23015-19-060). On July 28, 2020, the GC initiated transport of the
stockpiled soil to the Matheson Avenue location.

On behalf of the PD and GC, Wood notified the BFP via email on July 30, 2020 that there was a
discrepancy between the reported volume of stockpiled soil and the volume available for transport.In the
email correspondence, Wood reported that approximately 4,700 to 5,000 CY of soil may need to be
transferred to the Matheson Avenue sites for beneficial reuse (BR) and requested approval for transfer of
this volume. Based on the analytical data (five volatile organics and five composite samples (20 discrete
locations for semi-volatile organics and metals)) provided in Wood’s above-referenced letter report, the
characterization sampling and analysis would compute to one composite per 1,000 CY. In addition, the PD
retains Wood to perform continuous monitoring (field screening for volatile organics) during excavation
and truck loading.
As of the date of this letter, the hauling entity estimates that approximately 3,700 CY of stockpiled soil has
been transferred to the Matheson Avenue location. Based on that estimate, approximately 1,300 CY of
additional soil could be transferred to the Matheson Avenue locations. The GC estimates that the volume
of excess soil will exceed 1,300 additional CY. The GC further estimates that up to 7,800 additional cubic
yards of excess could be generated from the areas of the property represented by Wood’s BR data
referenced in the table below. The table below illustrates the number of characterization samples
collected and analyzed, the estimated volume of excess soil proposed for transport and the ratio of
samples per CY:

The PD/GC will coordinate with representatives of the recipient(s)to verify that the soil would be useful
for structural fill at the Matheson Avenue locations and Woodlawn Green.The redevelopment summary
report will document actual volumes of soil transferred to the approved destinations.
