Dear Ms. Tedrow:

The North Carolina Department of Environmental Quality (DEQ) Division of Waste
Management Brownfields Program received an original Brownfields Property Application
(BPA) on February 10, 2017 and a revised BPA on February 23, 2017 for the Hoke Street
Passage Home property located at 500 & 506 Hoke Street, and 1412 Garner Road in Raleigh,
Wake County. We have reviewed the documents submitted with this BPA and those documents
related to the Brownfields Property or immediate site vicinity that you or your consultant John
Gallagher provided on April 25, 2017, May 17, 2017, or June 14, 2017 via email. The following
is a summary of the reports and documents reviewed:

Based on our review of these documents, data gaps with respect to shallow soil, sub-slab vapor
or soil gas, groundwater, and the presence of certain historical sub-surface features were
identified. Additional information and assessment activities, as outlined below, are required to
assist in making risk management decisions for inclusion in the brownfields agreement (BFA).
Please submit a work plan prepared by an environmental professional for our review and
approval prior to conducting the field work at the Brownfields Property. The work plan should
include a description of the sampling and analytical methods to be utilized and a map depicting
the proposed sample and transect/survey locations with the parcel boundaries. The most recent
Inactive Hazardous Sites Program Guidelines for Assessment and Cleanup (Link) should be
used as guidance for sampling procedures and methodology. With respect to analytical lab data
packages, please request Level 2 QA/QC data packages from a N.C. certified environmental
laboratory. If obviously impacted soil is observed during the sampling, collect one duplicate
sample within the impacted area.

1) Additional information: Site Redevelopment
Based on our discussions at your office on April 24, 2017 and your BPA, we understand that
your plans for the Brownfields Property are the following:

1) 1412 Garner Road parcel (Parcel 1703920658)
 Composting via the bin system and bokashi method
 Growing and harvesting edible plants and flowers

2) 506 Hoke Street parcel (Parcel 1703920846)
 Storage of wood chips

3) 500 Hoke Street parcel (Parcel 1703828886)
 Use of the building to support community and economic
development activities, currently envisioned as a restaurant and
food/agricultural training center for people ages 16 and up.

Please provide additional information about these operations, using scaled drawings where
appropriate:
1. Please confirm the ages of people that will be frequenting the building and grounds as
visitors and of those working on the property in a full-time or part-time capacity.
2. What type of plants will be grown onsite?
3. What is the anticipated depth of the root zone of such plants?
4. What type of gardening will be implemented at the Property? Will plants be grown in
raised beds exclusively or in native soils?
5. Describe the planned structure of the proposed greenhouse and its location. Will it be
a permanent structure with a concrete floor and walls?
6. What are the products that may be sold at the Property?

2) Receptor Survey: Complete the enclosed Brownfields Property receptor survey and include
as an attachment to the Additional Assessment Report.

3) Additional Assessment: Sampling Activities

a) Surficial Soil Samples on 1412 Garner Road parcel (Parcel 1703920658): Collect a
minimum of twelve (12) surficial (0-2 ft) soil samples, unless the planned depth of
disturbance in soil for site activities will be deeper. A minimum of six (6) samples must
be collected in the open eastern area of this parcel that historically was used for trailer
and vehicle parking (refer to aerial photography in Phase I Environmental Site
Assessment (Proctor Environmental Services, June 31, 2016; Appendix D). A minimum
of five (5) surface soil samples must be collected from the western portion of this parcel.
Samples shall be collected in areas where direct contact with surface soils and soil
disturbance is anticipated and assessment data is not available. One (1) soil sample
should be collected from the area of the distressed vegetation in the southwest corner of
the back lot, identified in photograph #24 of the Phase I Environmental Site Assessment
(Proctor Environmental Services, June 31, 2016, Appendix B Site Photographs.)

b) Surficial Soil Samples on 506 Hoke Street parcel (Parcel 1703920846): Collect a
minimum four (4) surficial (0-2 ft) soil samples, unless the planned depth of disturbance
in soil for site activities will be deeper. Additional sampling is requested due to the
limited information as to the historic use of this parcel; limited assessment activities; the
1981 aerial photograph that shows vehicles parked on the parcel; presence of the adjacent
vehicle repair shop, and the 2005 aerial photograph provided in the Phase I
Environmental Site Assessment (Proctor Environmental Services, June 31, 2016) that
shows possible drum storage on the property and the loading area.

c) Background Soil Sample: Collect at least one surficial background soil sample for
analysis of RCRA Metals.

d) Sub-Slab/Soil-Gas Sampling: Potential risk for vapor intrusion in the onsite building at
500 Hoke Street (Parcel No. 1703828886) and on the Brownfields Property has not been
evaluated. Collect a minimum of four (4) sub-slab soil gas samples within the existing
building at 500 Hoke Street. Samples should be located throughout the building and at
least one (1) sample must be collected within the area of the former Nyetech 10 day
storage area, one (1) sample near the former fuel dispenser pad, and one (1) sample in the
southwestern area of the building. If any proposed renovation of the existing building
includes extending the building to the south, soil gas samples in the proposed footprint
should be collected. Depending on the structure of the proposed greenhouse additional
soil gas samples may be requested within the area of its planned footprint. The proposed
sub-slab and soil vapor sampling methods should be consistent with Division of Waste
Management Vapor Intrusion Guidance and referenced in the work plan. Include a
description of the field leak check methods, with our preference for the use of helium in
the field, in the work plan submitted for approval prior to sampling and ensure
communication with the laboratory that laboratory method detection limits and reporting
limits will be below applicable screening levels.

e) Groundwater Sampling: Collect groundwater samples, from wells MW-1, MW-2, MW-5,
& MW-6. Obtain groundwater data from the area on the west side of the auto service
station at the intersection of Hoke Street and Garner Road. Include proposed
groundwater sampling methods, well installation location and plans, and field parameters
in the work plan.

Analytical Laboratory Parameters
All samples will be analyzed by a N.C. certified laboratory under chain of custody protocol.

Soil
All soil samples should be submitted for laboratory analysis of VOCs by EPA Method 8260,
SVOCs by EPA Method 8270, RCRA Metals by EPA Method 6010, pesticides and
herbicides except that samples for VOC analysis should not be taken from the upper one foot
of soil. Deeper samples should be collected if warranted based on field screening results (PID
readings, visual and olfactory observations), or if the depth of disturbance in a particular area
will be more than two feet.

Sub-slab Vapor or Soil Vapor
Analyze all sub-slab /soil-gas samples for VOCs by EPA Method TO-15.

Groundwater
Groundwater samples should be sampled for VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, and RCRA Metals by EPA Method 6010.

Please note in the work plan that the reporting limits will be below applicable N.C. standards
or screening levels, and that the laboratory will be contacted to ensure such compliance. If
applicable reporting limits are in exceedance, re-sampling may be requested by the
Brownfields Program. Additionally, on the chain of custody, please request that the data be
provided in both Excel and PDF formats.

Report and Figures: Upon receipt of the analytical data package from the laboratory, provide
the data to me in excel format via email in advance of your full report. Submit a summary
report with a brief site history, a description of current and planned site operations, a
description of field activities, tabulated data collected in the field, tabulated data in
comparison to applicable screening levels, and the laboratory data packet in PDF format with
applicable QA/QC documentation. Report figures should include a site plan to scale with
sample locations, current site structures, and concentration map(s) for contaminants detected
above applicable standards or screening levels.

4) Geophysical Surveys:

a) Conduct ground penetrating radar (GPR) and electromagnetic induction (EM) surveys
near the dispenser pad on the northeast side of the building to determine if a reported
UST is present in the area. Per the Limited Phase II Environmental Site Assessment, 6
soil borings were installed near the dispenser pad and no visual or organoleptic evidence
Hoke Street Passage Home

of petroleum-impacted soil were reported for the soil borings (Figure 5 of the report
shows the locations of the soil borings). It is our understanding that samples from the
soil borings were examined with a PID meter and were not analyzed by a lab, please let
us know if this is incorrect.

b) Conduct GPR and EM surveys in the area where the “pit” was identified on the hand
drawn figures taken from January 21, 2004 NCDENR field notes and an April 14, 2004
Nyetech NOV Response. The figures were included in the June 31, 2016 Phase I (pages
145 and 187, respectively). The location of the pit is estimated to be near the southwest
corner of the back lot on the 1412 Garner Road parcel (Parcel 1703920658). The pit has
been described as a “rolloff buried in the ground”, “pit”, and “mixing agent stockpile”.

In the work plan, include a description of the method used to conduct the surveys and a
figure showing the planned locations of the transects relative to the dispenser pad and
estimated location of the pit.

We look forward to receiving your work plan discussed above. If you have questions about this
correspondence or require additional information, please feel free to contact me by phone at 919-
707-8382 or by email at [e-mail].

Sincerely,

Sarah Hardison Young
Brownfields Project Manager
