Phase I Environmental Site Assessment
Municipal Building
301 Hillsborough Street
Raleigh, North Carolina
H&H Job No. RAL-001

1.0 Findings, Opinions, and Conclusions

On behalf of the City of Raleigh, Hart & Hickman, PC (H&H) has performed a Phase I
Environmental Site Assessment (ESA) on a 0.5-acre parcel of land and office building located at
301 Hillsborough Street in Raleigh, Wake County, North Carolina. This ESA was conducted in
general conformance with the scope and limitations of ASTM-E 1527-05, and CERCLA’s Small
Business Liability Relief & Revitalization Act (Brownfields Amendments) of 2002 (101)(35)(B),
All Appropriate Inquiries (AAI), Final Rule, published by U.S. EPA in the Federal Register on
November 1, 2005, effective November 1, 2006. Any exceptions to, or deletions from, this
practice are described in this report. A summary of the findings of the site assessment is
presented below.

• The subject site is comprised of 0.5 acre of commercial property in a mixed commercial
and residential area of downtown Raleigh that had originally been developed as
residential property; the current building was constructed in 1957 with an addition added
in 1975.
• The area in the vicinity of the subject site is a mix of residential and commercial
properties.
• H&H did not observe evidence of a water supply well or septic system on the site; the
property utilizes municipal utilities for potable water and sewage disposal.
• A review of the environmental database report indicated that no environmental incidents
associated with the subject site have been reported on a local, state or federal regulatory
agency database.

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
• H&H observed locations at which other investigators had identified asbestos-containing
building materials throughout the facility, and lead-based paint.
• Other than the ACBM and lead-based paint, H&H did not observe significant evidence of
hazardous materials on the property; H&H observed small quantities of gasoline for use
in emergency generators that were properly stored in a locked, flammables cabinet, and
multiple bags of de-icing compound in the on-site metal warehouse.
• H&H observed the use of a corrosion inhibitor compound for building maintenance use;
the compound was stored in containers that were noted to be in good condition. There
was no evidence of spills or staining of the concrete floor from this compound.
• H&H did not observe evidence of soil staining, stressed vegetation, or unusual mounds or
depressions.
• A five feet by four feet sump was observed in the boiler room in the basement; the pit
walls appeared to be in good condition; however, the base of the sump could not be
inspected as it was covered with approximately 24 inches of standing water.
• Historical evidence indicates that past on-site operations included operation of a
calibration laboratory during occupation of the building by Instrument Society of America
(ISA); however, there is no indication of the on-site storage of large quantities of
chemicals.
• Historical evidence indicates that past off-site operations in the site vicinity, which
include a gasoline service station to the north (300 Hillsborough Street), mortuary with
associated gasoline and heating oil USTs and former dry cleaning operations to the south
(317 W. Morgan Street), and a heating oil tank release to the northeast (220 Hillsborough
Street) may impact subject site groundwater due to the proximity of these sites to the
subject site and the inconclusive data regarding groundwater flow direction.
This assessment has revealed evidence of one recognized environmental condition (REC)
and two potential environmental conditions (PECs) in connection with the subject site:

3 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
• REC #1: Groundwater contaminants stemming from the former Lozupone/Shell Oil
property at 300 Hillsborough Street, identified releases from underground storage tanks
(USTs) at the former Instrument Society of America (ISA) property at 317 W. Morgan
Street, and identified releases from a former UST located at the NC Democratic Party
Headquarters property at 220 Hillsborough Street have a moderate to high potential to
impact the subject site.

Recommendation: H&H recommends sampling groundwater at the site to identify
whether any potential off-site sources of petroleum hydrocarbon contamination or
potential chlorinated solvent contamination have impacted the site property. Although
not identified as RECs, the following two potential environmental concerns (PECs) were
identified in connection with the subject site:

• PEC #1: Asbestos-containing building materials (ACBM) (floor tile and associated
mastic, baseboard mastic, exterior window caulking, TSI, fireproofing, and roof system
materials containing asbestos at concentrations greater than 1%) were previously
identified at the site by others. H&H understands that affected TSI joints were replaced;
however, most of the ACBM has not been removed from the site.

Recommendation: H&H recommends that the previously identified ACBM be addressed
in accordance with the Communications of Hazards section found in the Occupational
Safety Health Administration (OSHA) Standard 1926.1101. H&H also recommends that
the ACBM found in friable condition, or the non-friable materials that would be rendered
friable during renovation or demolition activities, be removed by a certified asbestos
abatement contractor prior to any future demolition or renovation activity.

• PEC #2: Several painted surfaces have been identified by others as containing lead-based
paint (LBP) (ex. on the ladder in room 002, stair components of the front and back stairs,
and on the stairs and railing in the boiler room.) These materials do not appear to have
been removed.

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc

Recommendation: H&H recommends implementation of interim controls, including
paint film stabilization on substrates in good sound condition, continued visual inspection
and maintenance until eventual abatement, and dust control on the LBP surfaces. H&H
also recommends evaluating abatement options, including encapsulation, enclosure, on-
site paint removal, or component replacement of the LBP surface. Cleaning of the facility
after completion of interim controls or abatement options are conducted, including
completing a LBP clearance inspection (visual inspection and dust wipe samples) is also
recommended.

2.0 Introduction

This report presents the results of a Phase I ESA for a 0.5-acre parcel of land and municipal
building located at 301 Hillsborough Street in Raleigh, Wake County, North Carolina (“subject
site”). This assessment was conducted for the City of Raleigh pursuant to their Brownfields
Assessment Grant (Cooperative Agreement BF-96416704-0) with the U.S. Environmental
Protection Agency (EPA), and in accordance with our authorized scope of work.

2.1 Purpose and Scope of Services

The purpose of this assessment was to identify, to the extent feasible pursuant to the processes
prescribed herein, recognized environmental conditions in connection with the property. Such
environmental conditions include the presence or likely presence of hazardous substances or
petroleum products on the property under conditions that indicate an existing release, a past
release, or a material threat of a release of hazardous substances or petroleum products in
structures on the property, or into the ground, ground water, or surface water on the property.

2.2 Methodology Used

This Phase I ESA was performed in general conformance with ASTM procedure E 1527-05,
Standard Practice for ESAs: Phase I Environmental Site Assessment Process, and is consistent
with CERCLA’s Small Business Liability Relief & Revitalization Act (Brownfields
Amendments) of 2002 (101)(35)(B), All Appropriate Inquiries (AAI), Final Rule, published by
U.S. EPA in the Federal Register on November 1, 2005, effective November 1, 2006. The
assessment process consisted of four primary tasks:
• records review;
• interviews with the current owner/occupants of the property and with local government
officials regarding the property (as appropriate);
• site reconnaissance; and
• evaluation and report preparation.

3.0 Site and Area Description

3.1 General Site Description and Use
The subject site is comprised of an approximately 0.5-acre parcel of land and office building
located at 301 Hillsborough Street in Raleigh, Wake County, North Carolina (PIN# 1703-59-
6095). The site is comprised of a four-story office building and parking areas. The site is
bounded by Hillsborough Street to the north, S. Dawson Street to the east, W. Morgan Street to
the south, and an asphalt-paved public parking facility to the west. A site location map is
included as Figure 1. A site map that also illustrates potential off-site sources of contamination
is included as Figure 2. Site photographs are provided in Appendix A.

3.2 Description of Site Structures and Improvements
The subject site consists of a five level (basement level and four above-ground stories) L-shaped
office building, loading dock, and metal warehouse, with a building footprint of approximately
11,200 square ft. This building is located within a primarily commercial and government-related
office area, at the southwest intersection of Hillsborough Street and S. Dawson Street, three
blocks west of the State Capitol Building. A small parking area immediately fronting the
building along Hillsborough Street is surfaced with paver stones; a small parking area at the rear
of the building is paved with asphalt. The rear of the building is accessed via W. Morgan Street.

According to Wake County real estate records, the site building was originally constructed in
1957, with an addition constructed in 1975. An enclosed metal warehouse for the storage of
miscellaneous equipment and materials is located immediately adjacent to the rear loading dock,
and is accessible from W. Morgan Street. Two waste dumpsters, one for trash and one for
recycled materials, are located adjacent to the rear loading dock.

9 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
The office portion of the building is of conventional brick and exposed steel construction with
two central heating and air conditioning (HVAC) systems, one for the original building and one
for the addition. The roof is of tar and gravel construction, which is sloped to the roof drains.
Separate HVAC units, including cooling towers, are located on the roof, with components of the
HVAC systems accessible through mechanical rooms on each floor of the building. The building
is served by two elevators; one in the lobby and one near the rear entrance. The rear elevator is
operated by a hydraulic mechanism.

The boiler room is located at the northwest end of the building in the basement level. Separate
boilers heat the original building and the addition. The boilers for the addition are located within
a pit in the boiler room. A concrete-lined sump is also located in this pit.

At the time of the site visit, the office space was occupied by a variety of City Departments,
including City Police Units, City Surveying units, and Mechanical, Fire, Plumbing, and Electrical
Inspection Departments. Portions of the site, primarily the fourth floor and portions of the third
floor, were unoccupied.

The majority of the property is covered by the building footprint and either asphalt paving or
paver stones. Only small portions of the property are landscaped in planters or planter beds.

3.3 Property Owner, Manager, and Occupants
H&H reviewed the real estate records of the subject site on the Wake County website
(www.wakegov.com). Real estate and tax records indicate that the subject site is owned by the
City of Raleigh. The property notes do not indicate that any environmental liens are in place
against the property, nor does a search of the Register of Deeds website available through
www.wakegov.com. A copy of the subject site’s Wake County real estate data record is
provided in Appendix B.

10 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
H&H was not provided with, nor did H&H perform, a chain-of-title search, for this property.
Available deed records go back to 1946 and are available through the county website noted
above. They indicate that the property was purchased by the City of Raleigh from Instrument
Society of America (ISA) in December 1998. ISA had purchased the property from the Baptist
State Convention in 1982, which had originally constructed the office building in approximately
1956-1957, after purchasing the property from Boylan-Pearce, Inc. in 1953. The property
transferred ownership only between individuals prior to that time.

3.4 Vicinity Characteristics

The area in the vicinity of the subject site is comprised of a mix of residential, commercial,
governmental and church-related properties. The subject site is bounded by the following:

• North – Hillsborough Street with a gravel-covered parking lot (former gasoline station at
300 Hillsborough Street) and the Clarion Hotel across the street.
• Northeast – Sacred Heart Church, school buildings and parking lot
• East – S. Dawson Street and commercial building known as Hillsborough Place
• South – W. Morgan Street and new condominiums, including ground-level storefronts
(some still vacant)
• West – asphalt-paved public parking lot

3.5 Physical Setting

Topography
The property is in a densely developed urban area of downtown Raleigh (United States
Geological Survey (USGS) topographic quadrangle map, 7.5 minute series, Raleigh West, NC,
1988). It is located at an elevation between 340 to 350 ft. above mean sea level (msl).
Available topographic information indicates that the site is situated near the top of a topographic
high oriented from northwest to southeast, with the topographic gradient in the area of the site
generally to the southwest as shown in Figure 3, Site Topographic Map.

11 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
Geology

The subject site is located in the Piedmont Physiographic Province of North Carolina. According
to the Geologic Map of North Carolina dated 1985, the subject site lies within the Raleigh Belt
of the Piedmont. The Raleigh Belt is composed of a suite of metamorphic rocks; the downtown
Raleigh area is generally underlain by biotite gneiss and schist intruded by sills and dikes of
granite, pegmatite, aplite, and minor hornblende gneiss.

In the Piedmont, the bedrock is overlain by a mantle of weathered rock termed saprolite or
residuum. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of
rock fragments. Due to the range of parent rock types and their variable susceptibility to
weathering, the saprolite ranges widely in color, texture, and thickness. Generally, the saprolite
is thickest near interstream divides and thins toward streambeds. In profile, the saprolite
normally grades from clayey soils near the land surface to highly weathered rock above the
competent bedrock.

The occurrence and movement of ground water in the Piedmont is typically within two separate
but interconnected water-bearing zones. A shallow water-bearing zone occurs within the
saprolite, and a deeper water-bearing zone within the underlying bedrock.

Ground water in the shallow saprolite zone occurs in the interstitial pore spaces between the
grains comprising the saprolite soils. Ground water in this zone is typically under water table or
unconfined conditions. Ground water movement is generally lateral from recharge areas to small
streams that serve as localized discharge points.
The occurrence and movement of ground water in the underlying water-bearing zone within the
crystalline bedrock is controlled by secondary joints, fractures, faults, and dikes within the
bedrock. On a regional scale, the direction of ground water flow is typically from uplands to
major streams and ground water sinks. The saprolite has a higher porosity than the bedrock and
serves as a reservoir that supplies water to a network of fractures in the bedrock.

In addition to the above listed sites, H&H reviewed a list of unmappable orphan sites included
within the EDR database report. Orphan sites do not contain sufficient address information in
the environmental databases to plot them on a map. Based upon our reconnaissance of the
surrounding area, none of the orphan sites were located in the vicinity of the subject site.

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
Subject Site
The subject site was not identified by the EDR report as a property of environmental concern.

Site Vicinity Properties
H&H reviewed regulatory agency files for properties in the site vicinity of the subject site that
were identified immediately adjacent to, or within ¼ to ½ mile of the subject site. Regulatory
agency files were reviewed for the following properties in the site vicinity:
1) Lozupone Property/Shell Oil, (former gasoline station) located immediately north of the
site at 300 Hillsborough St.;
2) Former Instrument Society of America; 317 W. Morgan St., immediately south of the
property;
3) City of Raleigh Municipal Building, 222 W. Hargett St.
4) Democratic Party Headquarters, 220 Hillsborough Street, one block northeast of the
subject site.

A discussion of these sites based on available documentation or communication through the
relevant regulatory agencies is provided in Section 4.2 below. All of the remaining database
listings identified by EDR appear to have a low potential to impact the subject site due to their
distance from the subject site, site vicinity topography, and observed or presumed groundwater
flow direction in the area.

4.2 Other Records Review

Previous Site Investigations
Four previous site investigation reports were available for the subject site. These are:
1) Mid-Atlantic Associates, P.A., October 20, 1998. Report of Phase I Environmental Site
Audit with Limited Asbestos and Lead-Based Paint Survey, ISA Building, 301
Hillsborough Street, Raleigh, North Carolina.
2) Titan Atlantic Group, October 30, 2003. Asbestos Survey at Municipal Building, 301
Hillsborough Street, Raleigh, North Carolina.
15 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
3) Titan Atlantic Group, October 30, 2003. XRF Lead-Based Paint Inspection Report, 301
Hillsborough Street, Raleigh, North Carolina.
4) Engineering Consulting Services, Ltd., November 22, 2005, Limited Asbestos Sampling,
301 Hillsborough Street, 4-Story Building, Raleigh, Wake County, North Carolina.

The results of the previous investigations included the following environmental concerns:

Identification of ACBM
• Identification of asbestos in concentrations greater than 1% in floor tile and associated
mastic, baseboard mastic, exterior window caulking, thermal system insulation (TSI),
and hard TSI joint samples throughout the building interior (Titan, October 2003).
Additional materials found to contain greater than 1% asbestos included fireproofing
throughout the building and roofing material (ECS, November 2005).
• Asbestos-containing TSI and hard TSI joints and exterior window caulking were
considered friable materials in good condition, and therefore regulated asbestos-
containing material (RACM).
• Asbestos-containing floor tiles, floor tile mastics and baseboard mastics were
considered Category I non-friable materials in good condition.
• Recommendations made by others regarding ACM were the following:
o Removal of any RACM by a qualified asbestos abatement contractor prior to
renovation or demolition of the structure.
o Removal of any Category I ACM by a qualified asbestos abatement contractor
prior to renovation or demolition due to the potential of damage and becoming
friable with disturbance.

Identification of LBP
• Identification of LBP using a portable LPA-1 Lead Paint Spectrum Analyzer (XRF) at
concentrations greater than 1.0 milligrams per square centimeter (mg/cm2) on a ladder
in room 002, stair components of the front and back stairs, and on the stairs and
railing in the boiler room.

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
• Recommendations made by others regarding the LBP were as follows:
o Use interim controls, including paint film stabilization on substrates in good
sound condition, continued visual inspection and maintenance until eventual
abatement, and dust control.
o Evaluate abatement options, including encapsulation, enclosure, on-site paint
removal, or component replacement.
o Cleaning of the facility after interim controls or abatement options conducted,
including completing a LBP clearance inspection (visual inspection and dust
wipe samples.)

The results of the previous investigations also resulted in the recognition of one potential off-site
environmental condition:

Lozupone Property (former gasoline service station) at 300 Hillsborough St.:

Additional information obtained from a search of regulatory agency records on this site is
provided below.

Fire Department
H&H made inquiries of the City of Raleigh Fire Department concerning records of fires or
chemical spills on or near the subject site. Mr. A.C. Rich of the City of Raleigh Fire Marshall’s
office indicated that according to his records, which date back to 1983, there have been no
incidents in which a hazardous materials team has responded to at 301 Hillsborough St. (personal
communication, April 17, 2006).

H&H made inquiries of the City of Raleigh Fire Department, Office of Fire Protection regarding
UST installation or closure permits issued in this area (personal communication, April 17, 2006
and May 3, 2006). A response from this department was not available at the time of this report.
Information from this office will be provided in an addendum to this report if relevant to site
conditions.

NC DENR
H&H reviewed Superfund files available at the NC DENR, Oberlin Road facility, and the LUST
and Groundwater section files available at the NC DENR Raleigh Regional Office in Raleigh,
NC. The information provided below was obtained from these files.

Lozupone Property/Shell Oil
The Lozupone Property at 300 Hillsborough St. lies immediately north of the subject site. The
site is currently a gravel-covered parking lot used by the neighboring Clarion Hotel. Historically,
the site was operated as a gasoline station as early as 1940 through 1980.

Five underground storage tanks (USTs): two 10,000-gallon gasoline, one 6,000-gallon gasoline,
one 550-gallon waste oil, and one 550-gallon fuel oil, and associated product lines were removed
from the property in 1989 (Groundwater Technology, Site Summary, November 1992). A series
of subsurface investigations including soil borings and the installation of 18 monitoring wells on-
and off-site (MW-1 through MW-9, and GT-1 through GT-5, SP-1, VP-1 through VP-3), and
monitoring events were conducted from 1989 through 2000. A Geoprobe soil sampling program
was also conducted in May 2000 (EMS Environmental, Inc., Site Closure Report, August 3,
2000).

The depth to groundwater ranged from 38 to 48 feet below ground surface. Available water level
data indicated that the groundwater flow direction was to the northeast, generally away from the
subject site; however, there was one reporting period in which it appeared that groundwater flow
was toward the southwest.

Soil and groundwater contamination with mineral spirits, benzene, toluene, ethylbenzene,
xylenes, MTBE, IPE, and lead was detected on- and off-site in excess of state standards.
Benzene concentrations in groundwater at this site ranged up to 2300 ug/L in MW-2, toluene up
to 5400 ug/L in MW-4, ethylbenzene up to 3200 in MW-4, xylenes up to 10,000 in MW-2,
methyl tertiary butyl ether (MTBE) up to 90 in MW-4, isopropyl ether (IPE) up to 75 ug/L in
18 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
MW-6, and lead up to 9 ug/L in MW-6 (EMS Environmental, Inc., Groundwater Monitoring
Report, May 8, 2000).

One groundwater monitoring well, GT-5, was installed on October 31, 1991 on the south side of
Hillsborough St. near the western boundary of the subject site at 301 Hillsborough St. (then
owned by Instrument Society of America), and the adjacent motel that was present at that time.
The total depth of GT-5 is reported to be 55 feet below ground surface, with the screened interval
between 30 to 55 feet and a well diameter of 4 inches. Groundwater concentrations in GT-5
were initially non-detect; however sampling in September 1999 and April 2000 (the last known
sampling event) indicated 5.8 and 5.0 ug/L of benzene and 2.7 ug/L toluene. EMS
Environmental argued that the concentrations were generally decreasing in all wells (EMS
Environmental, Inc., Groundwater Monitoring Report, May 8, 2000), yet this does not appear to
be the case in the area screened by well GT-5. Rather, the available data suggest that a benzene
concentrations were increasing near the subject site when monitoring ceased. A copy of a
representative groundwater concentration map is provided in Appendix G.

Site remediation included: 1) the excavation of approximately 1,560 cubic yards of
contaminated soil in two separate events in 1990 and 1991, 2) the installation of a soil vapor
extraction (SVE) and air sparging (AS) systems in February 1993, and 3) operation of these
systems until 1996. DENR issued a Notice of No Further Action at the site based on a low risk
designation and public notice requirements of residual petroleum hydrocarbon contamination on
September 3, 2000.

The groundwater remediation system has been removed from the property at 300 Hillsborough
St. It is unknown whether the wells at 300 Hillsborough were closed or whether they were
simply covered with gravel; however, well GT-5, located near the subject site, appears to still be
accessible. Based on the close proximity of this site to the subject site, and its location near a
topographic divide, which may also serve as a hydrologic divide, the groundwater contamination
at the 300 Hillsborough St. site may impact the subject site.

Instrument Society of America
The former Instrument Society of America (ISA) site is at 317 W. Morgan St., immediately south
of the property. ISA had purchased the property from the Baptist State Convention in 1983. ISA
sold the property on September 8, 2000 to the Morgan Street Partners, who developed the site
into condominiums.

Phase I site assessment activities in anticipation of the upcoming real estate transaction lead to
the identification of former USTs and past use for two dry cleaning operations at the site
(Engineering Consulting Services (ECS), March 29, 2000). A petroleum hydrocarbon release
was discovered during the removal of two orphaned 560-gallon fuel oil USTs at the site on
August 19, 2000 (Engineering Consulting Services, Ltd, Orphan Underground Storage Tank
Closure Report, August 30, 2000). At that time the site was used as a parking lot.

During the tank closure, approximately 39 tons of contaminated soil was excavated; however,
excavation was limited by the presence of a former building foundation. Soil samples collected
from the excavation ranged from ND to 11,100 ppm TPH-DRO and from ND to 599 ppm TPH-
GRO.

Three groundwater monitoring wells, MW-1 through MW-3, were installed at the site on May
13, 2000, August 19, 2000, and August 24, 2000, respectively (ECS, Limited Site Assessment
(LSA), October 6, 2000). Wells were installed to depths ranging from approximately 38 feet in
MW-3 to 60 feet in MW-2. Static water level is noted as 30 feet in all three wells. Water level
measurements to enable a calculation of the groundwater flow direction and gradient were not
reported. Lithologies at the site were reported to be silty sands and silty clays overlying
weathered rock. A series of eight geotechnical borings were also drilled at the site in May 2000.

A geophysical survey using ground-penetrating radar (GPR) was conducted at the site to identify
the potential UST and concrete substructures. A test pit investigation was conducted on August
5, 2000 to further investigate subsurface geophysical anomalies detected during the GPR survey.

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc

Selected soil samples from the boring for MW-3 were submitted for chemical analysis by EPA
Method 8260, EPA Method 8270, MADEP VPH/EPH. Soil samples from MW-3 were in excess
of residential soil standards for 2-methylnapthalene and C9-C22 Aromatics.

One groundwater sample from MW-1 was submitted for EPA Method 6210D (Volatile
Organics), EPA Method 8270 (Semi-Volatile Organics) and EPA Method 8315 (Formaldehyde).
One groundwater sample was submitted from MW-2 for EPA Method 6210D (Volatile
Organics), and one groundwater sample was submitted from MW-3 for EPA Method 602
(Volatile Organics), EPA Method 625 (Semi-Volatile Organics), and MADEP VPH/EPH.

Analytical results indicated the detection in the MW-1 samples of chloroform and toluene at 1.0
ppb and bis(2-ethylhexyl) phthalate at 10 ppb. Formaldehyde and other VOCs were not detected.
Only benzene at 2.1 ppb was detected in the groundwater sample from MW-2. Analytical results
from the MW-3 groundwater sample indicated high concentrations of benzene (495 ppb), toluene
(2,030 ppb), ethylbenzene (520 ppb), xylenes (5,200 ppb), and naphthalene (74.9 ppb), which
were in excess of their respective 2L standards. A map of the groundwater concentrations
detected at this site is provided in Appendix G.

The NCDENR issued a Notice of No Further Action to the Morgan Street Partners for the site on
January 5, 2001 (date on document erroneously indicates January 5, 2000). Currently, the site is
occupied with residential condominiums with ground-level storefronts.

Based on the proximity of this site to the subject site, and inconclusive groundwater flow
direction data, the groundwater contamination present at the former ISA site may impact the
subject site.

NC Democratic Party Headquarters
The NC Democratic Party Headquarters site is located at 220 Hillsborough St., which is
approximately one-half block to the east of the subject site. The site is the location of a release
21 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
from a 1000-gallon heating oil UST that was discovered upon site renovation activity. The UST
was removed on March 19, 2002.

Petroleum hydrocarbons were detected in site soils in exceedance of residential maximum soil
contaminant concentrations (TPH GRO ranged from 930 to 1,840 mg/kg; TPH DRO ranged from
6510 to 21,600 mg/kg). Groundwater was investigated at the site through the installation of one
shallow monitoring well. Target contaminants were not detected in the on-site well above the
method detection limits, except for 220 ug/L C9-C22 aromatics. It was not possible to extract
groundwater flow direction information from the documents on this site, as only one monitoring
well was installed.

Due to the proximity of this property, the lack of groundwater flow direction information and the
presence of the topographic high in this location, it is possible that groundwater contaminants at
this property may migrate to the subject property; however, additional groundwater elevation
data would be necessary to fully evaluate the flow direction in this location.

Summary of Off-site Investigations
Given the proximity of the sites and available groundwater flow direction data, and based on the
available documentation of the potential off-site sources of contamination discussed above, H&H
believes the groundwater contaminants stemming from the former Lozupone/Shell Oil property
at 300 Hillsborough Street, the former ISA property at 317 W. Morgan Street, and the NC
Democratic Party Headquarters property at 220 Hillsborough Street could impact the subject site.
Additional groundwater elevation data would be needed to more fully evaluate groundwater flow
direction in this specific location. The location of potential sources of off-site contamination to
the subject site are noted on Site Map and Potential Sources of Contamination (Figure 2.)

Additional sites with historic uses that have the potential to impact the subject site were
identified through historical Sanborn Map review. These sites are discussed below in Section 4.3
and are also noted on Site Map and Potential Sources of Contamination (Figure 2).

State Historic Preservation Office
Maps available at the State Historic Preservation Office (SHPO) Survey Planning Branch and the
Office of State Archaeology (OSA) offices in Raleigh, NC were reviewed to identify whether the
site was located on the National Historic Register or was in a state archaeological area of interest.
According to available SHPO maps of Raleigh, the site is not listed on the National Historic
Register, nor is under consideration for listing on the National Historic Register.

According to maps available with the OSA and Ms. Delores Hall, State Archaeologist (personal
communication, April 20, 2006), the subject site is not located in a state archaeological area of
interest.

U.S. Department of Interior, Fish & Wildlife Service
The U.S. Department of Interior, Fish & Wildlife Service, Raleigh Field Office responded to our
inquiries by indicating that site assessment activities that may be conducted on the site are not
likely to adversely affect any federally-listed endangered or threatened species (USDOI, March
28, 2006).

4.3 Historical Use Information

Interviews

In order to obtain historical information concerning the past operations on the subject site, H&H
interviewed Mr. Billy Jackson, Building Maintenance Superintendent, and Mr. Chuck
Pemberton, one of his building maintenance staff. A summary of the interviews is provided
below.

Mr. Billy Jackson, City of Raleigh Building Maintenance Superintendent, was interviewed for
information concerning environmental conditions at the subject site. Mr. Billy Jackson did not
know of any environmental conditions of concern at the property, except for the asbestos-
containing building materials (ACBM) and lead-based paint (LBP) detected by others previously
in portions of the building (discussed in Section 4.2.)
23 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc

Mr. Chuck Pemberton indicated that the City of Raleigh stores hazardous materials such as
gasoline and unused paints, spray enamels, and other maintenance chemicals, in a locked
flammables cabinet in the metal warehouse. The gasoline is used to fuel several emergency
back-up generators at the facility.

A corrosive scale and corrosion inhibitor, with the tradename Ancool 3393 (manufactured by
Anderson Chemical Co. in Macon, GA), is stored in the boiler room and used in the HVAC
system to prevent biological growth. An MSDS for Ancool is provided in Appendix D. The
ingredients of Ancool 3393 are listed as sodium molybdate and sodium hydroxide. Eye, skin
and respiratory protection are required when handling this chemical as acute hazards include
severe irritation to eye, skin, and mucous membranes. No chronic hazards are noted.

Mr. Pemberton was not aware of any ASTs or USTs at the site.

Aerial Photographs
Aerial photographs dated 1965, 1971, 1981, and 1993 were provided through EDR Aerial Photo
Decade Package dated February 8, 2006 (Appendix E). Aerial photographs available through the
Wake County GIS mapping website (http://impas.co.wake.nc.us) include aerial photography of
the subject site and vicinity in 1999, 2002 and 2004. No aerial photographs depict the subject
site prior to the construction of the existing building. The following is a summary of the findings
of the aerial photograph review:

• 1965 (original scale 1”= 750’): The subject site and the surrounding properties are
densely developed. The original building configuration is visible on the subject site. The
former gasoline station across Hillsborough Street to the north is also visible. A long
rectangular building, believed to be a motel, is immediately adjacent to the west.
24 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
• 1971 (original scale 1”= 750’): The subject site appears similar to the 1965 aerial
photograph; the building addition and the warehouse structure has not been added on as
of yet. The former gasoline station is visible to the north; the circular present-day Clarion
Hotel building to the north (formerly Holiday Inn) has been constructed by this time; a
parking lot is present to the east.
• 1981 (original scale 1”= 833’) The subject site and surrounding properties appear to
remain similar to the 1971 aerial photograph; however, the construction of the building
addition is observable. The building to the south has been replaced by a parking lot.
• 1993 (original scale 1”= 833’): The subject site and surrounding properties remain
similar to the 1981 aerial photograph with the exception that the metal warehouse on the
subject site is visible and the former gasoline station buildings are not observed.
• 1999 (http://imaps.co.wake.nc.us; scale not provided – interactive variable scale): The
subject site remains similar to the 1993 aerial photograph. The surrounding properties
remain similar to the 1993 aerial photograph with the exception that the adjacent building
to the west has been replaced with a parking lot, and the parking lot to the east has been
replaced with the Hillsborough Place building.
• 2002 (http://imaps.co.wake.nc.us; scale not provided – interactive variable scale): The
subject site remains similar to the 1993 aerial photograph. The former gasoline station
property to the north appears to be cleared with smaller structures visible along the
eastern edge of the property.
• 2004 (http://imaps.co.wake.nc.us; scale not provided – interactive variable scale) The
subject site is similar to the 2002 aerial photograph. The site immediately to the south
appears to be undergoing construction and the former gasoline station site appears to have
been regarded. The site and surrounding properties are consistent with the present
knowledge of site configuration and use. A copy of the 2004 aerial photograph is also
provided in Appendix E.

City Directories
H&H reviewed City and Cross Reference Directories dated 1935 through 2005 (approximate
five-year intervals) at the Olivia Raney History Library in Raleigh, NC. City directories with
25 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
coverage of the subject site indicate that the subject facility was occupied by the Baptist State
Convention from at least 1955 until at least 1980, and by the Instrument Society of America by at
least 1985. No occupant was identified in the City Directories for 1990 and 1995. Starting in at
least 2000, NC State Social Services and in 2005, City and State offices are listed at this address.

City directories also indicate that the site immediately to the north of the subject site, was
operated continuously as a gasoline service station from at least 1940 through 1970. No
occupant was identified in the City Directories from 1975 through 1985.

Sanborn Fire Insurance Maps
H&H reviewed Sanborn Fire Insurance Maps that were available through the EDR Sanborn Map
Report dated February 8, 2006 (Appendix F.) Sanborn Map coverage was available for the
subject site and vicinity for the years 1896, 1903, 1909, 1914, 1950 and 1972. A search of
Sanborn Map coverage accessible on www.nclive.org through the Wake County Public Library
electronic database indicated that no additional maps were available for this area. The
information gleaned from the Sanborn Maps is provided below:

1896: The earliest Sanborn Map of the subject site indicates that the property was a residence.
The surrounding property appears to be residential.

1903: The 1903 Sanborn Map is similar to the 1896 map.

1909: The 1909 Sanborn Map is similar to the 1903 and 1896 map in terms of site use. A school
is present in the site vicinity to the west.

1914: The 1914 Sanborn Map is similar to the 1909 map in terms of site use.

1950: The 1950 Sanborn Map provides the first major change in the subject site and vicinity site
use. The southern one-third of the subject site is noted as “Used Auto Sales” although the
original residence appears to still be present at the site. An enclosure of some kind is noted at the
26 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
southwestern edge of the parcel, which may reflect the sales office for the auto dealership. The
property to the north is clearly designated as a “Filling Station” and the property to the south is
listed as an “Undertaker”.

1972: The 1972 Sanborn Map notes the original footprint of the State Baptist Convention
building on the subject site, the location of the former gasoline station and hotel to the north, the
undertaker operation to the south and the “Downtowner Motor Inn” immediately adjacent to the
site to the west. A small circular symbol at the undertaker operation marked G.T. is believed to
represent a gasoline tank. This is presumed to be the UST that was recently discovered at the
317 W. Morgan St. property (see Section 4.2.)

Historical Use Summary
Based upon the historical information reviewed, the subject site was developed as a residential
property from as early as 1896 through approximately the early 1950s. The Baptist State
Convention purchased the property in 1953 and developed the site with a commercial office
building in 1957. ISA purchased the site in 1982 and continued to own the facility until the City
of Raleigh purchased the site in 1998. It has served as a state and/or municipal office building
since that time.

Off-site property use has historically included gasoline service stations, mortuary operations, and
motel/hotels. According to a 1960 Sanborn Map that was referenced in a previous report, dry
cleaning & laundry facilities were also formerly located at 317 W. Morgan Street.

5.0 Site Reconnaissance

A visual reconnaissance of the site was conducted by Ms. Sharon Eckard of H&H on April 12,
2006. Ms. Eckard was accompanied on the site reconnaissance by Mr. Chuck Pemberton, with
the City of Raleigh Building Maintenance Department. The weather conditions were sunny with
temperatures near 80°F. Photographs of the exterior and representative interiors of the building
are provided in Appendix A.

The exterior of the property was inspected along with the interior basement and first floor
through fourth floor levels, including mechanical rooms and the boiler room. The rooftop was
also accessed during the site reconnaissance. Certain rooms in the building that were used as
Police Department storage areas and other police activities were not accessible due to security
and/or privacy reasons.

5.1 Hazardous Substances

H&H identified four gasoline cans and a variety of spray and liquid paint and enamel containers
that were stored in a locked, flammables metal cabinet in the metal warehouse. Also stored in
the warehouse were multiple bags of de-icing compound for exterior walkways and driveways.
All containers appeared to be in good condition and H&H observed no evidence of chemical
spills or staining on the floor below the stored materials. Other surplus equipment and
furnishings were stored in the warehouse.

H&H also identified two plastic drums of corrosive scale and corrosion inhibitor concentrate
(Ancool #3393) and one drum of diluted Ancool solution in the boiler room located on the
basement level. The Ancool solution is used for maintenance of the buildings’ HVAC systems.
The containers appeared to be in good condition and H&H observed no evidence of spills or
staining on the concrete floor below the drums. An MSDS for this chemical is provided in
Appendix D.

28 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
H&H also identified several locations where suspect ACBM and lead-based paint sampling was
conducted by others during previous investigations (discussed in Section 4.2). H&H did not
collect additional samples for ACBM or lead-based paint as this was outside of our agreed upon
scope of services.

5.2 Storage Tanks and Sumps

No USTs or ASTs were observed on the subject site and none were reported by the site contacts
Mr. Billy Jackson or Mr. Chuck Pemberton. One concrete-lined sump was observed in the boiler
room pit floor. According to the original building plans from 1955, the sump was constructed of
six-inch concrete and is five feet deep by four feet wide. At the time of the inspection, the pit
had approximately 24 inches of standing water at the base. The sidewalls of the pit appeared to
be in good condition; however, due to the standing water it was not possible to visually inspect
the base of the sump. The sump receives from the nearby eye wash station, and from piping
from the two original coal-fired boilers. The boilers have since been converted to natural gas.

5.3 Water and Wastewater Issues
The property utilizes municipal utilities for potable water and sewage disposal. No water supply
wells or sanitary septic systems were noted at the subject site and none were reported by site
contacts Mr. Jackson or Mr. Pemberton.

During the site reconnaissance, three sewer line clean-out locations were noted in the rear
parking lot near W. Morgan St. These clean-out locations were also noted on site building plans
for the building addition constructed in 1972. The most westerly clean-out was noted to have a
loose cap.

5.4 Indications of PCBs

Polychlorinated biphenyls (PCBs), a potential environmental contaminant, are sometimes found
in mineral oils used in electrical equipment including transformers or in older hydraulic oils used
for elevator systems. Older electrical distribution panels present in the boiler room and
29 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
potentially elsewhere in the facility may contain PCB oils. The elevator near the rear entrance to
the building uses a hydraulic system (Dover Controller), which is maintained by Southern
Elevator. The elevator room was clean and did not indicate leakage or spills of oils on the floor.

H&H observed three pole-mounted transformers located along the western boundary of the
subject site. Progress Energy supplies electricity to the site area. Previous investigators had
determined that these transformers were non-PCB bearing; H&H confirmed this by noting the
existence of a blue dot on the transformers signifying that they are a non-PCB type. The
transformers identified at the site appeared to be in good condition. No evidence of an oil spill
was observed to the transformers protective casings, pole, or to the ground surface below the
transformers. The transformers are the responsibility of Progress Energy, and the landowner is
not responsible for leaks or spills from the site transformers.

5.5 Indications of Waste Disposal

Two waste dumpsters at the subject facility were noted to be in good condition. One receptacle
was placed on a concrete surface; the other on asphalt. Although there was some staining and
cracking of the asphalt pavement surface, there was no evidence of unauthorized waste disposal
observed at the subject site. General waste generated at the facility is reportedly collected by the
City of Raleigh sanitation service.

5.6 Surface Conditions

The ground surface surrounding the site building is either covered with asphalt, paver stones,
concrete sidewalk, or small, unmaintained, landscaped areas. No areas of concern, such as
stressed vegetation or significant staining were observed during the site reconnaissance.

30 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
5.7 Stormwater

Stormwater generated at the site flows into the subsurface municipal storm sewer in this area.

H&H reviewed the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map
(FIRM) data presented on EDR Overview and Detail Map within the EDR database report
(Appendix C). The flood data in the EDR report indicates that the subject site (Panel
37183C0343E) is not located within the 100 or the 500-year flood plains

5.8 Asbestos Containing Building Materials (ACBM)

Asbestos-containing building materials (ACBM) (floor tile and associated mastic, baseboard
mastic, exterior window caulking, TSI, fireproofing, and roof system materials containing
asbestos at concentrations greater than 1%) were previously identified at the site by others. H&H
understands that affected TSI joints were replaced; however, most of the ACBM has not been
removed from the site.

H&H recommends that the previously identified ACBM be addressed in accordance with the
Communications of Hazards section found in the Occupational Safety Health Administration
(OSHA) Standard 1926.1101. H&H also recommends that the ACBM found in friable condition,
or the non-friable materials that would be rendered friable during renovation or demolition
activities, be removed by a certified asbestos abatement contractor prior to any future demolition
or renovation activity.

5.9 Lead-Based Paint

H&H noted several painted surfaces during the site visit that have been identified by others as
LBP. LBP sampling conducted by others during previous investigations identified LBP at the
following locations: ladder in room 002, stair components of the front and back stairs, and on the
stairs and railing in the boiler room. The areas identified with LBP are discussed further in
31 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
Section 4.2. H&H did not conduct additional screening for or collect additional samples for LBP
as this was outside of our agreed upon scope of services.

H&H recommends implementation of interim controls, including paint film stabilization on
substrates in good sound condition, continued visual inspection and maintenance until eventual
abatement, and dust control on the LBP surfaces. H&H also recommends evaluating abatement
options, including encapsulation, enclosure, on-site paint removal, or component replacement of
the LBP surface. Cleaning of the facility after completion of interim controls or abatement
options are conducted, including completing a LBP clearance inspection (visual inspection and
dust wipe samples) is also recommended.

6.0 Summary

On behalf of the City of Raleigh, Hart & Hickman, PC (H&H) has performed a Phase I
Environmental Site Assessment (ESA) on a 0.5-acre parcel of land and municipal office building
located in Raleigh, Wake County, North Carolina. This ESA was conducted in general
conformance with the scope and limitations of ASTM-E 1527-05 and CERCLA’s Small
Business Liability Relief & Revitalization Act (Brownfields Amendments) of 2002 (101)(35)(B),
All Appropriate Inquiries (AAI), Final Rule, published by U.S. EPA in the Federal Register on
November 1, 2005, effective November 1, 2006. Any exceptions to, or deletions from, this
practice are described in this report. A summary of the findings of the site assessment is
presented below.

• The subject site is comprised of 0.5 acre of commercial property in a mixed commercial
and residential area of downtown Raleigh that had originally been developed as
residential property. The current building was constructed in 1957 with an addition
constructed in 1975.
• Historical evidence indicates off-site operations in the site vicinity include a gasoline
service station to the north (300 Hillsborough Street), mortuary with associated gasoline
and heating oil USTs, and former dry cleaning operations to the south (317 W. Morgan
Street), and a heating oil tank release to the northeast (220 Hillsborough Street). These
former off-site operations may impact subject site groundwater due to proximity to the
subject site. Available data regarding groundwater flow direction are inconclusive.
• The property utilizes municipal utilities for potable water and sewage disposal, and H&H
did not observe evidence of a water supply well or septic system on the site.
• A review of the environmental database report indicated that no environmental incidents
associated with the subject site have been reported on a local, state or federal regulatory
agency database.
• H&H observed locations at which other investigators had identified asbestos-containing
building materials (ACBM) throughout the facility, and lead-based paint (LBP).

\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
• Other than the ACBM and lead-based paint, H&H did not observe significant evidence of
hazardous materials on the property; H&H observed small quantities of gasoline for use
in emergency generators that were properly stored in a locked, flammables cabinet, and
multiple bags of de-icing compound in the on-site metal warehouse.
• H&H observed the use of a corrosion inhibitor compound for building maintenance use;
the compound was stored in containers that were noted to be in good condition. There
was no evidence of spills or staining of the concrete floor from this compound.
• H&H did not observe evidence of soil staining, stressed vegetation, or unusual mounds or
depressions.
• A five feet by four feet sump was observed in the boiler room in the basement; the pit
walls appeared to be in good condition; however, the base of the sump could not be
inspected as it was covered with approximately 24 inches of standing water.
• Historical evidence indicates that past on-site operations included a calibration laboratory
run by Instrument Society of America (ISA); however, there is no indication of on-site
storage of large quantities of chemicals.
This assessment has revealed evidence of one recognized environmental condition (REC)
and two potential environmental conditions (PECs) in connection with the subject site:

• REC #1: Groundwater contaminants stemming from the former Lozupone/Shell Oil
property at 300 Hillsborough Street, identified releases from underground storage tanks
(USTs) at the former Instrument Society of America (ISA) property at 317 W. Morgan
Street, and identified releases from a former UST located at the NC Democratic Party
Headquarters property at 220 Hillsborough Street are judged to have a moderate potential
to impact the subject site.

Recommendation: H&H recommends sampling groundwater at the site to identify
whether off-site sources of petroleum hydrocarbon contamination or chlorinated solvent
contamination have impacted the site property.

34 Hart & Hickman, PC
\\hhfs01.harthickman.local\masterfiles\AAA-Master Projects\City of Raleigh - RAL\RAL-001\301 Hillsborough\Phase I Report\RAL-001 301 Hillsborough Phase I.doc
Although not identified as RECs, the following two PECs were identified in connection with the
subject site:

• PEC #1: Asbestos-containing building materials (floor tile and associated mastic,
baseboard mastic, exterior window caulking, TSI, fireproofing, and roof system materials
containing asbestos at concentrations greater than 1%) were previously identified at the
site by others. H&H understands that affected TSI joints were replaced; however, most of
the ACBM has not been removed from the site.

Recommendation: H&H recommends that the previously identified ACBM be addressed
in accordance with the Communications of Hazards section found in the Occupational
Safety Health Administration (OSHA) Standard 1926.1101. H&H also recommends that
the ACBM found in friable condition, or the non-friable materials that would be rendered
friable during renovation or demolition activities, be removed by a certified asbestos
abatement contractor prior to any future demolition or renovation activity.

• PEC #2: Several painted surfaces have been identified by others as containing lead-based
paint (ex. on the ladder in room 002, stair components of the front and back stairs, and on
the stairs and railing in the boiler room.) These materials do not appear to have been
removed.

Recommendation: H&H recommends implementation of interim controls, including
paint film stabilization on substrates in good sound condition, continued visual inspection
and maintenance until eventual abatement, and dust control on the LBP surfaces. H&H
also recommends evaluating abatement options, including encapsulation, enclosure, on-
site paint removal, or component replacement of the LBP surface. Cleaning of the facility
after completion of interim controls or abatement options are conducted, including
completing a LBP clearance inspection (visual inspection and dust wipe samples) is also
recommended.
