Subject: REVISED LIMITED PHASE II ENVIRONMENTAL SITE ASSESSMENT
500 AND 506 HOKE STREET
RALEIGH, WAKE COUNTY, NORTH CAROLINA PES PROJECT NUMBER: R16-161
Dear Mr. Alexander: At your request, Proctor Environmental Services, Inc. (PES) has prepared this summary report for the above-referenced Site, located as shown on Figures 1 and 2. The objective
of our scope of services was to follow-up on the findings of our June 31, 2016 Phase I
Environmental Site Assessment prepared on behalf of Passage Home, a party interested
in purchasing the subject property. As discussed in the Phase I ESA, the following recognized environmental conditions (RECs) were discovered associated with the Property:
• The Site was identified in four regulatory databases in the EDR report related to a former lessee of Site, Nyetech Environmental Solutions. Further review of the EDR report indicated that a release was reported at the Site on January 22, 2004 and Incident Number 86897 was issued by the underground storage tank (UST)
Section of the NCDENR (now the NCDEQ);
• An underground petroleum storage tank (UST) was potentially present and reportedly removed from the Site approximately 50 years ago. An apparent
dispenser pad was observed adjacent to the northeast corner of the building on the Site; and
• The property adjacent to the northeast corner of the Site, located at 1400 - 1402 Garner Road, is currently known as the Old Garner Road Food Mart and also appears in use as an automotive repair service operation. Based upon the presence of an apparent fuel dispensing island, it appears to have been a full-service automotive repair and fueling station in the past. Due to the possible former

Raleigh, North Carolina
presence of petroleum USTs and automotive repair services at the adjacent site,
it could pose a possible environmental risk to the Site.
The remainder of this report summarizes our findings related to the aforementioned Nyetech incident, the possible on-site former petroleum UST and the adjacent former automotive repair service operation and our assessment activities, findings, and
recommendations for the current environmental conditions at the Site.
HISTORICAL BACKGROUND The Comments section of the EDR report, a portion of which can be found in Appendix A, indicate that the North Carolina environmental regulatory agency became aware of
Nyetech’s activities at the Site in January of 2004. Listed as a “LAST” or leaking aboveground storage tank, the EDR report states that “A waste hauler mixes Lq. (i.e. liquids) with saw dust to make a solid, then transport the solids to Earth Tech in Sanford NC. Ten roll backs full of materials and leaking on the ground. Petro and solvents, and
other petroleum products leaking. samples pulled and NOV (i.e., Notice of Violation) sent,
further action pending the samples data.” The source of contamination was listed as “spill-surface” and the groundwater contamination status was listed as “unknown.” Based upon soil samples collected and analyzed both before and after limited remedial actions, semi-volatile organic compounds are present in the soil behind the building and the Site Incident remains open.
Based upon these findings on the Site, a PES representative visited the Raleigh Regional Office of the NCDEQ Underground Storage Tank Section to review the incident file. A copy of the information from the files can be found in Appendix B. The following
documents were copied and reviewed for this report:
• January 21, 2004 – Initial Site Visit Notes and Complaint about Nyetech
• January 22 and 23, 2004 – Groundwater Section Staff Report and Photos
• January 23, 2004 - NCDENR Notice of Violation (NOV)
• March 25, 2004 – Request for Fast Track Enforcement against Nyetech
• April 14, 2004 – Nyetech Response to NOV
• May 11, 2004 – John Alexander Correspondence to NCDENR Our review of these documents indicated that on January 21, 2004, Nyetech personnel were observed by a third party “solidifying stuff in a roll off buried in the ground” in the lot behind the building on Hoke Street. Their operations appeared to be “very sloppy and
there was antifreeze spilled on the ground.” NCDENR personnel visited the site to
observe and photograph the operations and collect representative soil samples for laboratory analysis. NCDENR personnel further stated that there were eight to twelve roll off boxes full of contaminated soil awaiting off-site transport which were leaking onto the surrounding ground. A hand drawn, unscaled map of the back lot and sample locations
collected during the NCDENR site visit is attached as Figure 3. As shown, regulatory personnel collected three samples (Nos. 1, 2, and 3) from around the five roll-off boxes

Raleigh, North Carolina
located in the southeastern portion of the back lot. The site drawing also indicates several more roll-off boxes in the central portion of the back lot, at least two oil containers located in the northwestern portion of the back lot, and a “pit” located in the southwest portion of the back lot.
According to the NCDENR laboratory report in Appendix B and as summarized in Table 1, it appears that sample 1 was analyzed for oil and grease, sample 2 was analyzed for 10 metals, and sample 3 was analyzed for semi-volatile organic compounds. The NCDENR laboratory analysis revealed the presence of oil and grease, numerous metals
and various semi-volatile organic compounds (SVOCs) in excess of the laboratory’s
quantitation limits. Specifically, our review of the analytical results of the NCDENR samples indicated an oil and grease concentration in sample 1 of 220 mg/Kg, which exceeds the NCDENR Action Level of 10 mg/Kg. Of the ten metals tested, with one exception, none exhibited concentrations in excess of their NCDEQ Inactive Hazardous
Substances Branch (IHSB) residential, industrial, or protection of groundwater preliminary soil remediation goals (PSRGs). The single exception was manganese from sample 2, which exhibited a concentration of 160 mg/Kg. The protection of groundwater PSRG for manganese is 65 mg/Kg.
Several SVOC constituents, including fluoranthene, pyrene, benzo(a)anthracene,
benzo(a)pyrene, benzo(b)fluoranthene, chrysene and indeno(1,2,3-cd)pyrene were detected in NCDENR sample 3 in excess of either their IHSB Industrial and/or Residential Health-Based Soil Remediation and/or Protection of Groundwater Goals. These
constituents are polynuclear aromatic hydrocarbons (PAHs), which are typically produced
by the incomplete combustion of organic matter, such as in engines and incinerators. They are typically associated with used oil. The NCDENR Hazardous Waste Section, Compliance Branch issued a Notice of Violation (NOV) to Nyetech on January 23, 2004 citing numerous regulatory violations and stating
that the releases of “used oil” must be stopped, contained and cleaned up. A March 25, 2004 “Request for Fast Track Enforcement Against Nyetech” was present in the file but appeared to be in draft form as it was not completed. There was no indication in the file that the enforcement action correspondence was ever transmitted to Nyetech.
An April 14, 2004 letter from Nyetech to the NCDENR in response to the NOV was reviewed. According to Nyetech’s letter, which was not prepared or sealed by a professional engineer or geologist, Nyetech’s General Manager stated that they had “emptied and cleaned residual from inside all seven roll-off containers, and excavated to approximately one foot below grade from the impacted area resulting in 176.21 tons of
soil to be hauled” off-site for disposal. The letter report and associated drawing (see Figure 4 in this report), do not indicate from where on the back lot the excavation occurred, only that it was within the “impacted area”.

Raleigh, North Carolina
Upon completion of the limited excavation work, Nyetech subsequently performed a sampling event to collect laboratory samples for analysis. The samples were apparently collected from the soil below the area(s) of excavation and were perhaps composited instead of grab samples. According to the Nyetech letter report, three samples (#1, #2,
and #3) were analyzed by the laboratories according to Methods 8270, 602, and for the eight RCRA metals. Our review of the analytical results, as contained in Appendix B and summarized in Table 2, indicates that the concentrations of the SVOC constituents benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene and indeno(1,2,3-cd)pyrene exceeded either their IHSB Industrial and/or Residential Health-
Based Soil Remediation and/or Protection of Groundwater.
Although the field notes in the NCDENR Incident file are not thorough, it would appear that the NCDENR personnel-collected samples were grab samples and surficial in nature while the Nyetech-collected samples were possibly composited and collected from below
the excavated soil at a depth of approximately one foot below ground surface. With the exception of one constituent, benzo(k)fluoranthene, all of the constituents detected in the Nyetech-collected post-excavation samples were also present in NCDENR samples, only at significantly lower concentrations. PES SAMPLING ACTIVITIES
PES personnel visited the site in July and August of 2016 to conduct limited soil and groundwater assessment activities at the areas of suspected impact based upon our
review of the NCDENR and Nyetech information discussed above.
Soil Sampling Activities On July 28 and 29, 2016, seventeen (17) soil borings, located as shown in Figure 5, were
advanced and sampled around the back lot of the site, focusing on the northwest and
southeast quadrants where the roll-off boxes, oil containers, and NCDENR and Nyetech samples were reportedly located. The soil borings were continuously sampled using direct-push technology (DPT) sampling
methodologies to the terminal depths discussed below. Soil samples were collected using
a 4-foot long, 2¼ inch diameter, hollow-stemmed sampler with an acetate liner. This approach allowed us to visually inspect the soil for evidence of staining potentially related to possible releases. In addition, a photoionization device (PID) was used to screen the soil for emissions of volatile organic compounds (VOCs) typically associated with petroleum and volatile off-vapors and to select the soil interval most likely impacted for
laboratory analysis, if any. The extracted native soil generally appeared to be native reddish-brown silty clay. No areas of obvious fill material were observed in any of the borings. Finally, no elevated PID readings were recorded, indicating that no obviously impacted soil was encountered during the field screening activities. Boring logs are
contained in Appendix D.

Raleigh, North Carolina
Three (MW-1S, MW-2S, and MW-3S) of the 17 borings were ultimately converted into monitoring wells MW-1 through MW-3. These three borings were continuously sampled to a terminal depth of 30 feet bgs. Samples were collected for laboratory analysis from each of these three borings at depth intervals of 1’ to 3’ bgs and 8’ to 10’ bgs. (The soil
samples from boring MW-2S and MW-3S from the deeper interval were put on hold in the laboratory pending results from the shallow soil samples. Based upon the shallow sample analytical results, which did not exhibit any detectable concentrations, a decision was made no to analyze these two deeper samples.) The other 14 borings (S-1 through S-14) were advanced and continuously sampled to a depth of 10 feet below ground surface
(bgs). Samples were collected for laboratory analysis from each of these borings at depth
intervals of 1’ to 3’ bgs. Soil sample portions from each boring were placed in laboratory-provided glass sampling jars which were placed in insulated coolers containing ice for sample preservation. The
soil samples were transported under chain-of-custody protocols and shipped overnight to Prism Laboratories in Charlotte, North Carolina. The soil samples were analyzed for VOCs by Method 8260, semi-volatile organic compounds (SVOCs) by Method 8270, extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH) by the MADEP method, gasoline-range organics (GRO) by EPA Method 8015C,
herbicides and pesticides according to Methods 8080 and 8082, respectively, and the metals chromium and lead. The soil laboratory analytical results are summarized in Table 3 and a copy of the laboratory analytical report is contained in Appendix C. The soil
laboratory results are discussed later in this document.
Groundwater Sampling Activities – NE Property Corner, Old Garner Road Food Mart Two temporary groundwater monitoring wells (HokeTW-1 and HokeTW-2) were constructed immediately topographically downgradient (south side) of the automotive repair and food mart operation located at 1400 and 1402 Old Garner Road, located as shown on Figure 2. The wells, constructed to a terminal depth of 25 feet bgs, consisted of 10 feet of no. 10 slot screen at the bottom and then solid PVC riser pipe to the surface. Appropriately sized filter sand was then introduced into the annular space between the well and the boring walls such that the length of the screen was covered with filter sand,
which is designed to reduce the amount of fine, solid particles that enter into the well
through the machine-cut slots. Groundwater samples were collected using disposable polyethylene bailers after purging each well of at least three (3) well volumes to remove sediments and silts initially present within the well prior to sampling. The groundwater samples collected from the two temporary monitoring wells on July 27,
2016 were analyzed in the laboratory for VOCs by EPA Method 6200B. The groundwater laboratory analytical results are summarized in Table 4 and a copy of the laboratory analytical report is contained in Appendix C. The groundwater laboratory results are
discussed below. These temporary wells were abandoned immediately after sampling.

Groundwater Sampling Activities – Back Lot Area of 500 Hoke Street Subsequent to completion of the soil sample collection activities, the aforementioned soil borings (MW-1S, MW-2S, and MW-3S) were converted into groundwater monitoring wells
MW-1, MW-2 and MW-3, located as shown in Figure 6. Each groundwater monitoring well was constructed using one-inch diameter PVC well material. The wells consist of 10 feet of no. 10 slot screen at the bottom and then solid PVC riser pipe to the surface. Appropriately sized filter sand was then introduced into the annular space between the well and the boring walls such that the length of the screen was covered with filter sand,
which is designed to reduce the amount of fine, solid particles that enter into the well
through the machine-cut slots. Groundwater samples were collected using disposable polyethylene bailers after purging each well of at least three (3) well volumes to remove sediments and silts initially present within the well prior to sampling. Well construction details are summarized in Table 5 and copies of the well construction records are located
in Appendix D. Based upon the results of the groundwater analyses from the samples collected from the initial three wells, which are discussed below, an additional three wells, MW-4, MW-5, and MW-6, located as shown in Figure 6, were constructed in the same fashion as the original three wells.
Subsequent to well development, samples were collected from the monitoring wells using
disposable polyethylene bailers. The groundwater samples were slowly decanted into laboratory-provided sample bottles containing the appropriate preservatives. The sample bottles were placed in an insulated cooler containing ice for sample preservation and
transported under chain-of-custody protocols and shipped overnight to Prism
Laboratories. The groundwater samples collected from monitoring wells MW-1 through MW-3 on July 28, 2016 were analyzed in the laboratory for VOCs by EPA Method 6200B, SVOCs plus the 10 largest non-target peaks by Method 8270, MADEP VPH (aromatics) and the metals chromium and lead. The groundwater samples collected from monitoring wells MW-4 through MW-6 on August 24, 2016 were analyzed in the laboratory for VOCs
by EPA Method 6200B. The groundwater laboratory analytical results are summarized in Table 4 and a copy of the laboratory analytical report is contained in Appendix C. The groundwater laboratory results are discussed below.
Groundwater Flow Direction Determination Activities
Following installation of the six permanent groundwater monitoring wells, the
horizontal location of each well was referenced to existing, fixed landmarks on the
subject property. Additionally, the top of casing and ground elevation at each well
were surveyed and referenced to an arbitrary datum established at the site. On
September 6, 2016, the depth to liquid in each well was measured using an electronic
oil-water interface probe. The interface probe was decontaminated between each
well using an Alconox wash followed by a clean water rinse. The depth to
groundwater beneath the property ranged from approximately 24.5 feet bgs in well
MW-1 to 26.5 feet bgs in well MW-6, the hydraulically upgradient well. Free-product

petroleum was not detected on the groundwater surface in any of the groundwater
monitoring wells. Liquid level data are summarized on Table 5. Based on survey and
depth to groundwater data and as shown in Figure 7, the direction of groundwater
flow beneath the subject property is generally towards the south/southwest, which is
consistent with the general topography of the area of the site.
UST Investigation Activities
As stated in the Phase I ESA, an underground petroleum storage tank (UST) was
potentially present and reportedly removed from the Site approximately 50 years ago. An
apparent dispenser pad was observed adjacent to the northeast corner of the building on
the Site. During the assessment activities related to this report, six soil borings were
advanced and sampled in the vicinity of the possible dispenser pad, located as shown on Figure 5. The borings were advanced and sampled to a depth of approximately 20 feet
bgs and the soil was scanned for emissions of volatile organics. No visual or organoleptic
evidence of petroleum-impacted soil was discovered in the vicinity of the apparent
dispenser and the likely area of a former UST, if one was ever located at the site.
SUMMARY OF FINDINGS Based upon our limited assessment activities and observations at the site, we present the following findings and opinions:
Soil Analytical Results One constituent of concern was detected in the 18 soil samples submitted for analysis in excess of its regulatory standard. Specifically, beta-BHC (at 0.0015 mg/Kg) was detected
in sample B-7 at a depth of one to three feet bgs. The beta-BHC concentration was
flagged by the laboratory as a “J” value, indicating that, although detected, its concentration was below the laboratory’s Reporting Limit and therefore the result is an estimated concentration. This concentration exceeds the constituent’s IHSB Protection of Groundwater PSRG of 0.0012 mg/Kg. Beta-BHC is an organochloride and an isomer of
hexachlorocyclohexane, or HCH. It is a byproduct of the production of
the insecticide lindane (γ-HCH). According to the technical literature, it typically constitutes 5% to 14% of technical grade lindane, though it has not been produced or used in the United States for more than 30 years.
Another lindane-related constituent, delta-BHC, was detected in the same sample at a
concentration of 0.00049 mg/Kg. It too was flagged by the laboratory as a “J” value, indicating it’s an estimated concentrated. Delta-BHC does not have any listed regulatory remediation goals according to the IHSB.

Groundwater Analytical Results Two constituents of concern, tetrachloroethylene (also known as PCE) and trichloroethylene (TCE) were detected in groundwater at the site. TCE is typically
considered a degradation product of PCE when detected in the same sample at lower concentrations, which is the case at this site. PCE has a North Carolina groundwater standard of 0.7 ug/L and TCE has a standard of 3 ug/L. PCE was detected as follows:
• At a concentration of 0.73 ug/L in temporary monitoring well TW-1, which was located due south of the automotive repair shop located at the corner of Hoke Street and Old Garner Road; and
• As shown on Figure 8 and summarized in Table 4, PCE was detected in
groundwater samples collected from back lot monitoring wells MW-1, MW-2 and MW-3 at concentrations of 8.0 ug/L, 37.0 ug/L, and 0.58 ug/L respectively. TCE was also detected in the sample collected from well MW-2 at a concentration of 6.0 ug/L. No detectable concentrations of PCE were detected in the samples
collected from monitoring wells MW-4, MW-5, and MW-6. CONCLUSIONS
Based upon the soil and groundwater assessment activities conducted at the site, we
provide the following conclusions and recommendations:
• With one exception (and assuming that the sample location map is relatively accurate), it appears that Nyetech effectively removed adversely impacted soil
associated with their storage and blending operation on the back lot. The soil sample collected at a depth interval of 1 to 3 feet bgs at sample location S-7 exhibited beta-BHC at 0.0015 mg/Kg, just slightly in excess of its IHSB Protection of Groundwater PSRG of 0.0012 mg/Kg. None of the other soil samples exhibited analyte concentrations in excess of their respective regulatory standards;
• Groundwater below the southwestern quadrant of the back lot has been adversely impacted by PCE at concentrations in excess of its regulatory stand. PCE is a
chlorinated solvent used commercially as an industrial degreaser, spot remover,
and in dry cleaning operations. There is no known historical source of PCE storage or usage at the facility. Although it’s feasible that the Nyetech operations may have been the source, no PCE was detected in any of the soil samples collected by the NCDENR, Neytech, or Proctor Environmental. Based upon the groundwater flow direction under the site, which is towards the south/southeast, it’s likely that PCE
is migrating off the site and under the adjacent property to the south, the Former Cardinal Trucking site. It should be noted that the Cardinal Trucking Site has also been impacted by historical releases of PCE from the former Ashland Chemical Facility, which, as shown in Figure 2, is located adjacent to the west of the
southwestern portion of the subject site; and

• No visual or organoleptic evidence was found regarding the presence of an underground petroleum storage tank in the vicinity of the northeastern corner of
the building on the subject site. RECOMMENDATIONS
As summarized herein, the remaining known recognized environmental condition at the
Hoke Street property is PCE, a common industrial solvent, found in groundwater beneath the southwestern quadrant of the site at a depth of about 25 feet below grade. That portion of the site is currently undeveloped, and there is no current groundwater use at the entire site. Moreover, in Raleigh installation of groundwater water supply wells is prohibited.
Therefore, in the future, if development of this area were to occur, the remaining concern
is the potential for vapor intrusion and indoor air quality impacts due the groundwater
contamination. As a result, in the area of the site with groundwater impacts, any new development should avoid encountering groundwater, and further assessment of the vapor intrusion pathway
should be conducted to determine if groundwater contamination could pose a potential source of indoor air contamination to new structures and improvements. If a vapor intrusion risk were found, appropriate mitigation measures should be considered and incorporated into the development efforts.
