  11      Project Objectives
  The goal of Site remediation detailed in this SIP is to achieve compliance with applicable regulations
  as stated in 40 CFR 761 .61(a), 761 .61(c) and 761 .62(a) and the Regulations of Connecticut State
  Agencies (RCSA) Sections 22a-1 33k-I through 22a- 1 33k-3, inclusive, Remediation Standard
  Regulations (RSRs) and Sections 22a-463 through 469, inclusive of the Connecticut General
  Statutes, governing Polychlorinated Biphenyls (PCBs). This SIP only addresses environmental issues
  related to PCBs and includes an outline of the approach and procedures that Contractors will follow
  to ensure achievement of the remedial objectives.




  Self-Implementing Cleanup Plan
  Emmett O’Brien Technical High School
  January 2011                                                                                    Page 1
The remedial goals for the Site are as follows:

     •   To remove all PCB-containing caulking and glazing compounds associated \vjth exterior
         window systems, exterior door systems, exterior building expansion systems, exterior vent
         systems, and interior/exterior column    systemsclassified as PCB Bulk Product Waste that are
         to be disturbed by the proposed renovations to the site
     •   To remove all adjacent porous building materials (brick) within twelve (12) inches of the
         exterior building expansion systems and interior/exterior column systems contaminated with
         PCBs as PCB Bulk Product Waste that are to be disturbed by the proposed renovations to
         the site
     •   To remove all adjacent porous building materials (brick and/or block) within six (6) inches
         of the exterior wmdow systems contaminated with PCBs as PCB Remediation Waste that
         are to be disturbed by the proposed renovations to the site
     •   To remove all soil adjacent to the building with total PCB concentrations 1 PPM
         contaminated by PCB-containing caulking and/or glazing compounds classified as a PCB
         Remediation Waste.

An approach has been developed for this project to achieve the first remedial goal by removing
PCB-containing caulking and glazing compounds classified as PCB Bulk Product Wastes and
adjacent building materials. After removal, verification sampling will be performed. For this
project, the PCB Bulk Product Wastes and potentially impacted building materials will be considered
removed when all verification samples are <1 PPM total PCBs.

The second remedial goal is to remove all soil adjacent to the buildings with total PCB
concentrations ? I PPM contaminated by PCB containing caulking and/or glazing compounds
classified as a PCB Bulk Product Wast. In order to determine the soil removal boundaries, the soil
was characterized per 40 CFR Part 761 Subpart N (Subpart N). After removal of soil; verification
sampling will be performed per 40 CFR Part 761 Subpart 0 (Subpart 0). Soil characterization and
removal activities will be discussed further in subsections 2.4 and 3.6.

12       Non-Federally Regulated Building
         Material
In addition to this SIP to address federally-regulated PCB Bulk Product Wastes, the CT DPW and
CT DOE have coordinated with the Connecticut Departments of Environmental Protection (CT
DEP) and Public Health (CT DPH) to develop a scope of work to remove all PCB-containing
caulking and glazing compounds with total PCB concentrations 1 PPM and < 50 PPM that are not
classified as federally-regulated PCB Bulk Product Wastes.

January 2011                                                                                    Page 2
Following the removal of these building materials, the building materials formerly in contact will be
sampled. If total PCB concentrations in the remaining building materials are I PPM and the
material is scheduled to be left in place, then an encapsulant will be applied to the area where the
caulking and/or glazing compounds were in contact with building materials and new caulking or
glazing compounds will be applied.

Following the removal of these building materials, the building materials formerly in contact will be
sampled. If total PCB concentrations in the remaining building materials are 1 PPM and the
material is scheduled to be demolished, six (6) inches of the adjacent porous building materials will
be removed. Following removal, verification sampling will be performed to ensure that the
remaining building materials are 1 PPM.

The CT DEP and CT DPH have concurred with the proposed Scope of Work as described in
Appendix A.

t3      Site Description and Location
Emmett O’Brien Technical High School, built circa 1966 with renovations/additions reported in
1968 and 1975 and located in Ansonia, Connecticut, (see Figure 1 for aerial view of the site and
Figure 2 for building configuration), is part of the Connecticut Technical High School System which
provides students in grades 9-12 the opportunity to take courses in trades and technology as well as
the more typical high school academic courses.

It currently offers trade courses in culinary arts, hairdressing/barbering, carpentry, electrical, heating
ventilation and air conditioning, plumbing and heating, manufacturing technology, automotive
technology, electronics technology, graphics technology, information systems technology, and health
technology. It is approximately 125,000 square feet and situated in a wooded, residential area on
Prindile Avenue in Ansonia, Connecticut.

Original construction was performed in 1966. Renovation/addition activities were reported to have
occurred in the late 1960’s and mid 1970’s and they involved constructing classrooms and technical
rooms to the original building (classrooms 102-107, 201-209, electrical, auto, HVAC, and plumbing
shops as well as part of the cafeteria).

The locations of the building additions are shown on a site plan included as Figure 2 and a more
detailed description is as follows:

                Original building construction, now known as Classrooms 108-112, 210-219, Main
                Offices, gymnasium areas, part of the café/kitchen areas, library and carpentry,
                maintenance, industrial electrical, machine, tool and die shops.

                 1960/1970 Additions known as classrooms 102-107,, 201-209, electrical, auto,
                 HVAC, and plumbing shops as well as part of the cafeteria.


No large scale program was ever undertaken at the Site that would involve the removal of existing
compounds either for removal of asbestos-containing materials or for maintenance activities.
However, it does appear that small amounts of replacement caulking/glazing compounds were
added around parts of windows as repairs and were probably completed in very hintied instances.

Thus, it is considered unlikely that there are areas where PCB Bulk Product Waste caulks were
removed and replaced with caulks that might not have contained PCBs (treat whole area as
homogeneous).

1.4     Facility and Renovation Project
        Description
The total area of the parcel occupied by Emmett O’Brien ? res. On the property to the north of
the school building are baseball fields. The school buildin s located in the southern portion of the
parcel.

The school building is separated into two (2) distinct sections. A description of their current and
anticipated future uses and planned renovations is as follows:

            •   Original Building includes a first and second floor section consisting of educational
                classrooms and administrative offices, a gymnasium section consisting of a
                gymnasium and associated locker rooms, a library, demonstration room, and boiler
                room, and a shop section consisting of a carpentry shop, industrial electronic shop,
                maintenance shop, plastics shop, tool and die shop, and machine shop. Additionally,
                a stand alone garage structure is located to the west of the maintenance shop.
            •   Renovation activities in these sections of the building include construction of an
                addition off the east side of the gymnasium wing and the north side of the carpentry
                shop wing while the garage structure is to be demolished. Additional renovation
                activities include replacement of the exterior window systems and limited
                replacement of the exterior door systems along with extension interior remodeling.
                Remediation of PCB Bulk Product Wastes and associated Adjacent Building Material
                Substrates and Soil will be conducted prior to the renovation of these sections.
            •   It is estimated that the Original Building will have the following amounts removed:

                     •   Approximately Three Thousand Four Hundred (3,400) Liner Feet of
                         Exterior Window Caulking Compounds containing PCBs 50 PPM and One
                         Thousand Seven Hundred (1,700) Square Feet of Adjacent Building Material

2 SITE CHARACTERIZATION
21      Sampling Program Description
Sampling was performed:

             •    to categorize source materials such as interior and exterior caulking and glazing
                  compounds associated with exterior window, door, vent, building expansion, and air
                  conditioning systems that were be disturbed during proposed renovation activities
             •    to ascertain PCB concentrations within adjacent building materials such as brick that
                  are located adjacent to source materials identified to contain >50 PPM PCBs
             •    to characterize and delineate extent of impacts to soil, concrete, and asphalt that
                  may have been affected by flaking or deteriorating PCB Bulk Product Wastes

Connecticut. On October 20 and 26, 2010, and November 1, 15, 24, 29, and 30, 2010,
EnviroScience collected interior and exterior bulk caulking and/or glazing compound samples at
Emmett O’Brien Technical High School in Ansonia, Connecticut

Sampling methodology involved collecting grab samples per homogenous material type identified
following building material survey techniques generally employed in the Building Sciences industry
to identify, locate and sample homogeneous building materials (i.e. Asbestos Hazard Emergency
Response Act [AHERAI asbestos sampling guidelines).

The Environmental Protection Agency (EPA) Methods 8082/3540C (PCB analysis with soxhiet
extraction) was used for analysis at a State of Connecticut approved laboratory. Building materials
were grouped into one of three categories as defined in 761.3 under the federal regulations using
the following criteria:

    •   PCB Bulk Product Waste All caulking and/or glazing compounds with total PCB
                                       —



        concentrations 50 PPM were included in this category. A total of four (4) exterior caulking
        compounds, one (1) exterior window glazing compound, and two (2) interior caulking
        compounds met this criteria. An additional one (1) exterior caulking compound was
        assumed to meet this criteria due to inaccessibility issues related to sampling the building
        material.

    •   PCB Remediation Waste Caulking and/or glazing compounds with total PCB
                                       —




        concentrations l PPM but <50 PPM which were applied over a caulking and/or glazing
        compound with total PCB concentrations 5O PPM or where the concentration of the
        original caulking and/or glazing compound could not be determined. No large scale
        evidence of re-caulking and/or re-glazing was found at any of the sample locations. Thus,
        none of the caulking and/or glazing compounds were determined to be PCB Remediation
        Waste.

    •   Excluded PCB Products Caulking and/or glazing compounds were determined to be
                                       —




        Excluded PCB products if the determined in-situ total PCB concentration was <50 PPM
        and if it could be determined that the caulking and/or glazing compounds were original and
        that the total PCB concentration had not been modified by subsequent activities. As
        discussed above, all of the caulking and/or glazing compounds were determined to be
        original to building construction and there was no evidence that subsequent renovations had
        modified total PCB concentrations. Thus, three (3) exterior caulking and/or glazing
        compounds and four (4) interior caulking and/or glazing compounds were determined to be
        excluded PCB products.

The areas identified as containing PCB Bulk Products based upon sampling performed by TRC and
EnviroScience of homogenous material(s) are as follows:

23      Adjacent Building Material Substrate
        Sampling
Adjacent building material substrate samples were collected to determine the extent of removal of
adjacent porous building materials surrounding the bulk source material that were identified as PCB
Bulk Product Wastes.

Representative samples of adjacent porous building material substrates were collected a distance of
less than one (1) inch from the PCB Bulk Project Wastes. Additional representative samples of
adjacent porous building material substrates were collected a distance of six (6) inches from the PCB
Bulk Project Wastes in some limited areas.

In addition, concrete and/or asphalt samples were collected a distance of less than one (1) inch from
the base of the wall where the PCB Bulk Product Wastes were located.

Samples were collected following the EPA Region 1 Standard Operating Procedure for Sampling
Concrete at each of the locations. Samples were extracted and analyzed using EPA Methods 3540C
and 8082, respectively, and all analytical results were reported on a dry weight basis.

2.3i Exterior Adjacent BuUding Material
     Substrates
Twelve (12) samples (within one (1) inch of PCB Bulk Product Waste) were collected from the
adjacent exterior building material substrates throughout the original building in areas associated

Emmett O’Brien Technical High School
January2011                                                                                       Page 8
with exterior building expansion caulking compounds, exterior window caulking compounds, and
exterior door caulking compounds. Additionally, three (3) samples were collected from the exterior
building material substrates throughout the original building in areasassociated with exterior
building expansion caulking compounds at distances six (6) inches away from the PCB Bulk Product
Wastes.

Adjacent porous building material substrate sampling was also not performed for exterior window
glazing compounds, exterior vent caulking compounds located in the building addition, and/or
exterior column caulking compounds in the original building.

    •   Exterior window glazing compounds are only in contact with non-porous surfaces (glass and
        metal window frames), thus no sampling of adjacent porous building materials is needed.
    •   Exterior vent caulking compounds are inaccessible due to the height of the material and the
        adjacent building material substrates will be tested for PCB contamination following removal
        and remediated as necessary
    •   The adjacent building material substrates associated with the exterior column caulking
        compounds are assumed to be similar to the exterior building expansion caulking
        compounds and will be treated as such.

Samples collected were spread across the original building to evaluate the concentrations of PCB
within the adjacent porous building material substrates and the analytical results are in Table 2. Of
these samples, eight (8) were none-detect for PCBs, one (1) sample was < 1.0 PPM, three (3)
samples were >1 PPM and < 50 PPM. Two (2) samples were> 50 PPM.

Thus, sampling of the exterior adjacent porous building material substrates associated with PCB
Bulk Product Waste indicates the following:

            •   Removal of exterior window glazing compounds located on south side of cafeteria
                and associated metal window framing/window glass should be achievable by
                removing entire window frame unit
            •   Removal of exterior door caulking compounds located throughout original building
                and exterior vent caulking compounds from HVAC shop in building addition with
                no removal of adjacent porous building material should be achievable by removing
                entire door frame unit and/or vent frame unit, scrapping remaining caulking
                compounds from adjacent porous building materials, and cleaning the adjacent
                porous building materials
            •   Removal of exterior door caulking compounds located throughout original building
                with no removal of adjacent orous building material should be achievable by
                scrapping remaining caulking compounds from adjacent porous building materials
                and metal door frame, and cleaning the adjacent porous building materials and metal
                door frame

              •   Removal of exterior window caulking compounds located throughout original
                  building and interior window caulking compounds located at front entrance with
                  removal of six (6) inches of adjacent porous building material should be achievable
                  by removing entire window frame unit and removing six (6) inches of adjacent
                  porous building materials
              •   Removal of exterior column and building expansion caulking compounds located
                  throughout original building with removal of twelve (12) inches of adjacent porous
                  building material should be achievable by removing entire caulking compound and
                  removing twelve (12) inches of adjacent porous building material from each side of
                  caulking seam
              .
2.3.2 Interior Adjacent Building Material
      Substrates
No samples of interior adjacent building material substrates were taken.

The adjacent building material substrates associated with the interior window caulking compounds
are assumed to be similar to the exterior window caulking compounds and associated adjacent
buildings in the original building and will be treated as such. The adjacent building material
substrates associated with the interior column caulking compounds are assumed to be similar to the
exterior building expansion caulking compounds and will be treated as such if removal is required
based on proposed renovation activities.

2.3.3 Exterior Surfaces Adjacent to Building
Fifty (50) samples were collected from the concrete and/or asphalt located on the ground beneath
the locations of PCB Bulk Product Wastes in the original building. Grab samples were collected
within one (1) inch from the base of the building at the location of these wastes to assess the
potential for impacts to the adjacent ground substrates due to flaking and/or deteriorating of the
PCB Bulk Product Wastes.

Of the fifty (50) analytical results, forty eight (48) were none-detect for PCBs and two (2) results
were   <   1.0 PPM.

These analytical results indicate that there are no impacts to the concrete and/or asphalt
surrounding the original building that need to be remediated.

No concrete and/or asphalt sampling was performed in the areas of the building addition and/or
garage due to the limited amount of PCB Bulk Product Waste (exterior window glazing compounds
and exterior vent caulking compounds) associated with areas containing concrete and/or asphalt in
the building addition.

Analytical results are presented in Table 3 and the grab sample locations are shown on Figure 5.


24      Soil Sampling
Soil samples were collected from areas that are grassed or landscaped at locations beneath areas
where exterior PCB Bulk Product Wastes, either caulking and/or glazing compound, are located.

Analytical results are presented in Table 4 and the sample locations are shown on Figure 6, while
specific areas requiring remediation are detailed on Figures 7. Analytical data reports are included in
Appendix B.

The soil sampling was performed as follows:

            •   Initial grab soil samples were collected on October 14 and 15, 2010, within two (2)
                inches from the base of the building at ten foot intervals. Each of the grab samples
                were collected from surficial soil (0- to 4-inch interval). Composite samples were
                made by completely mixing aliquots of equal mass from two contiguous grab sample
                locations.

            •   A second round of grab soil sampling was performed on November 12, 2010, with
                the intent of completing the de]ineatton of PCB-impacted soil requiring remediation.
                 Where required to complete the vertical delineation, soil samples were collected at
                the same location as the previous initial grab soil samples, but at a depth of 4 to 8
                inches below grade. Additional sampling to complete the horizontal delineation was
                performed also. Since the PCB source material involves flaking from building
                caulks, the area affected was expected to be limited as it extends away from the
                building. Thus, sample intervals were reduced to 1.5 meters (or five feet) from the
                base of the wall and conducted at depth intervals of 0 to 4 inches and 4 to 8 inches.

            •   A third round of grab soil sampling was performed on November 24, 2010, with the
                intent of completing the vertical delineation of PCB-impacted soil requiring
                remediation. Where required to complete the vertical delineation, soil samples were
                collected at the same location as the previous two (2) rounds of grab soil samples,
                but at a depth of 8 to 12 inches and 20 to 24 inches below grade.

Unless otherwise noted below, the ground surface at the grab sample locations is covered with turf
and there is no evidence of any landscaping work having been performed. All surficial grab soil
samples were collected by removing turf at the sample location, shaking out the soil contained
within the turf into the exposed location, and then collecting a sample of surficial soil from 0 to 4
inches below grade. All grab samples collected at a depth of greater than 4 inches were collected by
hand augering to the desired depth (measured in the field) and then collecting a sample at the

desired depth. Soil removed by augering was replaced into the hole created at the same depths from
which it was removed to avoid mixing of potentially contaminated soil with clean.

All of the samples submitted were extracted using EPA Method 3540. Analysis of total PCBs was
performed using EPA Method 8082 and the total PCB concentration is based upon the mass of
Aroclors reported. All of the analytical data are reported on a dry-weight basis.

The following provides details concerning the delineation of PCB-impacted soil at each of the areas
where remediation will be required. Soil remediation excavation and verification sampling
procedures are discussed in Section 3.6.

2.4.1 Original Building East Side of
                                 —




      Gymnasium Wing
Initial soil composite sample locations for the east side of the gymnasium wing are shown on Figure
6. Initially, eight (8) surficial grab soil samples were collected from the ground surface beneath
vertical and horizontal caulking seams associated with the exterior window systems and exterior
building expansion caulk systems at this location. The ground surface was grassed and there was no
evidence of any landscaping work having been performed. All of these initial locations were located
within two (2) inches from the base of the building and spaced at ten feet intervals. Each of the
grab samples was composited for analysis as described above. Three (3) of the four (4) soil
composites submitted exceeded 0.5 PPM total PCBs (maximum composite sample result of 2.8
PPM total PCBs) and the remaining sample was none-detect indicating that additional
characterization sampling was required.

Additional characterization sampling was performed in order to complete the delineation and
determine the area requiring remediation. Grab soil samples were collected at a depth of eight (8) to
twelve (12) and twenty (20) to twenty four (24) inches at the original sample locations to complete
the vertical delineation. Analytical data, presented in Table 4, indicate that all of the samples at the
twenty (20) to twenty four (24) inch depth interval were none-detect and that a shallow excavation
of 1.5 to 2 foot would be sufficient to achieve remedial goals.

Grab soil samples at depths of zero (0) to four (4) and four (4) to eight (8) inches were collected a
distance of 5 feet horizontally away from the building at the original sampling locations in the
manner described above. These samples were submitted for analysis and determined to be none-
detect for PCBs and that any excavation performed at this location would not have to extend five
(5) feet from the building face.

The grassed area requiring remediation is approximately eighty (80) feet long. Assuming an
excavation of two (2) feet deep and extending five (5) feet from the base of the building,
approximately twenty mne (29) cubic yards (CY) of soil will be excavated to achieve remedial goals.

No additional characterization sampling is needed to determine the area requiring remediation in
this area.

2.4.2 Building Addition          —     South Side of
      Cafeteria Wing
Imtial soil composite sample locations for the south side of the cafeteria wing are shown on Figure
6. Initially, six (6) surficial grab soil samples were collected from the ground surface beneath
exterior window glazing compounds at this location. The ground surface was grassed with no
evidence of landscaping work having been performed. All of the initial sample locations were
located within two (2) inches from the base of the building and spaced at ten feet intervals. Each of
the grab samples was composited for analysis as described above.

Two (2) of the three (3) soil composites submitted exceeded 0.5 PPM total PCBs (maximum sample
result of 1.8 PPM total PCBs) indicating that additional characterization sampling was required in
this area.

Additional characterization sampling was performed in order to complete the delineation and
determine the area requiring remediation. Grab soil samples were collected at a depth of four (4) to
eight (8) inches below all of the original sample locations to complete the vertical delineation.
Analytical data, presented in Table 4, indicate that the samples were none-detect for PCBs indicating
that a shallow excavation of 1 foot below grade may be sufficient to achieve remedial goals.

Grab surficial soil samples were collected a distance of 5 feet horizontally away from the building at
depths of zero (0) to four (4) and four (4) to eight (8) inches. Analytical results indicate that that
samples were none-detect for PCBs and that any excavation performed at this location would not
have to extend five (5) feet from the building face at this location to achieve remedial goals.

The grassed area requiring remediation on the building addition south side of the cafeteria wing is
                                                                  —




approximately seventy (70) feet long. Assuming an excavation of one (1) foot deep and extending
on average five (5) feet from the base of the building, approximately thirteen (13) cubic yards (CY)
of soil will be excavated to achieve remedial goals.

No additional characterization sampling is needed to determine the area requiring remediation in
this area.

      Carpentry Wing
Initial soil composite sample locations for the east side of the carpentry wing are shown on Figure 6.
 Initially, five (5) surficial grab soil samples were collected from the ground surface beneath exterior

surface was grassed with no evidence of landscaping work having been performed. All of the initial
sample locations were located within two (2) inches from the base of the building and spaced at ten
feet intervals. Four (4) of the grab samples were composited for analysis as described above with
the fifth (5th) grab sample was sent in as a grab sample.

One (1) of the two (2) soil composites submitted exceeded 0.5 PPM total PCBs (sample result of
0.68 PPM total PCBs) indicating that additional characterization sampling was required in this area.

Additional characterization sampling was not performed in order to complete the delineation and
determine the area requirmg remediation. Thus the area requiring remediation is assumed to be
similar to the south side of the cafeteria wing.

The grassed area requiring remediation on the original building east side of the carpentry wing is
                                                                 —




approximately fifty (50) feet long. Assuming an excavation of one (1) foot deep and extending on
average five (5) feet from the wall, approximately nine (9) cubic yards (CY) of soil will be excavated
to achieve remedial goals.

2.4.4 Original Building West Side of
                                 —




      Machine and Tool & Die Shop Wing
Due to the existence of an elevated metal walkway that prevents access to the soil located adjacent
to the building, no sampling of the soil was performed in this area of the building. Based on soil
characterization in the areas adjacent to the metal structure (maintenance shop), it is assumed that
the soil does not contain PCBs greater than I PPM. If the metal structure is to be removed during
construction, the soil will be characterized, properly disposed of based on characterization, and
verification sampling performed if required.

The soil associated with the exterior expansion caulking compounds and exterior door caulking
compounds associated with the garage structure was never characterized. U         l

3 REMEDIATION PROCEDURES
PCB Bulk Product Waste (caulking and/or glazmg compounds), Adjacent Porous Building Material
(six and/or twelve inches from caulking compounds classified as PCB Bulk Product Waste), and
PCB Remediation Wastes (soils, see Section 2.4)will be removed utilizing abatement work practices
and engineering controls to limit the potential release of PCB dust/debris.

All materials will be containerized and then transported for appropriate disposal. The removal of
PCB Bulk Product Waste, Adjacent Porous Building Material, and Remediation Wastes will be
performed by a specialty contractor, utilizing workers afforded appropriate hazard communication
training, under the supervision of an appropriately educated and trained third party (field inspector)
who can validate appropriate removal techniques and confirm thorough removal of identified
materials.

The goal of building material remediation efforts is to ensure that all PCB Bulk Product Wastes and
the associated building materials are removed from areas that are being renovated and/or
demolished.

The guidelines provided below present the general procedures that are to be followed for the
removal of building materials and excavation of soil but the contractor vi1l have to determine exact
removal actions during the performance of the work.

With the exception of soils, as described in 3.6, no segregation of Federally- or non-federally
Regulated PCB wastes will be performed and materials will be removed together at each location.
This includes material generated during the removal of PCB-containing caulking and/or glazing
compounds with PCB concentrations <50 PPM. For this particular project, the remedial standard
for all verification samples will be total PCB concentrations <1 PPM. Achieving this remedial
standard at all verification sampling locations will allow for the remaining building materials to
remain in place and to be repaired during subsequent renovation activities. Section 3.5 discusses the
verification sampling in more detail.

3.1     Safety and Monitoring Requirements

It is anticipated that workers and students will use the Emmett O’Brien Technical High School
building while removal and abatement is ongoing. To prevent exposure of these persons to
contaminated dust, Control Areas will be established outside of the Regulated/Containment/Soil
Excavation Areas. Only properly trained personnel associated with the removal, abatement, and soil
excavation actions will be allowed within the Control Areas that will be established by placing
barriers with signs indicating that access to the area is restricted. The field inspector will maintain
the Control Areas and escort unauthorized personnel from the area promptly. Only those personnel
actively working on the removal, abatement, and soil excavation actions will be allowed within the
Regulated/Containment Area and they shall be equipped with Personal Protective Equipment
(PPE).

For interior removals, dust monitoring will be performed in the Control Area immediately outside
the Regulated/Containment Area prior to initiating the remedial action, during performance of the
action, and followmg the remediation which will include the break-down of the
Regulated/Containment Area. Monitoring will be performed for total suspended particulates (TSP).

The background concentration within each interior Control Area will be determined prior to
initiating remedial actions and a control area background level will be established. If, during the
performance of air monitoring during remediation, dust levels outside the Regulated/Containment
Area are observed to increase by 20-percent over the background level determined prior to the
remediation, the contractor shall be instructed to stop work, re-establish the regulated Containment
Area and associated engineering controls, and then will be required to decontaminate the remainder
of the Control Area outside Regulated/Containment Area prior to restarting work on the
rem ediation.

For soil excavation activities, the remedial contractor will be required to employ dust suppression
measures, most likely watering, to prevent dust generation. It is not anticipated that OSHA limits
for dust or PCB exposures will be approached. The dust suppression will be employed to prevent
the potential release of PCBs to the surrounding environment and the contractor will be directed to
employ dust suppression measures if any dust generation is observed.

12       Public Communication

Public outreach will be performed both prior to initiating and during the project to inform the
community of the activities that will be performed at the Site to address PCB contamination. The
scope and protocols to be followed are detailed in the attachment included in Appendix C.

33       Engineering Control Descriptions

Engineering controls to be implemented for interior and exterior remediation will follow along
similar guidelines as used when conducting asbestos abatement activities. That is, modeled after
OSHA Class I asbestos engineering controls for interior remediation work, and modeled after
exterior OSHA Class II asbestos engineering controls for exterior remediation work. A description
of these activities is as follows, while a more detailed description can be found in the PCB
Remediation Technical Specification located in Appendix G.

3.3.1 interior Remediation Procedures
Interior Remediation Procedures are as follows:

     •   Areas where PCB Bu]k Products will be removed are to be pre-cleaned using HEPA filtered
         equipment and/or wet methods as appropriate to collect all loose dust and debris which may


         contain PCB.
     •   After pre-cleaning, movable objects will be removed from the work areas. Fixed objects will
         be enclosed with one layer of six (6) mil polyethylene sheeting sealed with tape.

       •   Any openings between the Remediation Area and the non-remediation areas, including the
           outside of the building, will be sealed off with critical barriers consisting of a minimum of
           one (1) layer of six (6) n-ui polyethylene sheeting securing the edges with tape.
    •      A Negative Pressure Enclosure (NPE) will be constructed around the work area by covering
           of floor and wall surfaces with two (2) layers of six (6) mu polyethylene sheeting sealed with
           tape. Polyethylene will be applied alternately to floors and walls.
    •      The Contractor will create a negative pressure differential in the range of 0.02 to 0.04 inches
           of water column between the Remediaflon Area and surrounding areas by the use of
           acceptable HEPA filtered negative air pressure equipment. No air movement system or air
           filtering equipment will discharge unfiltered air outside the Remediation Area. The
           contractor shall continually monitor the pressure differential to ensure that the NPE is
           functioning appropriately and will stop work if the pressure differential is outside acceptable
           limits. Work will recommence after an acceptable pressure differential has been established.
    •      Signs will be posted outside the enclosure to deter unauthorized personnel from entering.
    •      Removal work practices within the regulated containment will be implemented which
           facilitate the removal of the PCB Bulk Product Waste and associated Building Material while
           also limiting the amount of dust and debris to be generated. The contractor will remove six
           (6) inches of adjacent porous building material substrates around the PCB Bulk Product
           Waste if required.
   •       All building materials removed during the remediation will be wrapped in poiy sheeting and
           transported to the waste storage area. The poiy sheeting will be secured with tape to ensure
           that no dust is released during the transport and the contractor will be responsible for the
           remedliation of any new releases caused by spillage.
   •       Verification sampling will be performed as described below to determine that all building
           materials, as outlined in this SIP, have been removed.

3.3.2 Exterior Remediation Procedures
Exterior remediation procedures are as follows:

       • Where necessary, the ground adjacent to and beneath areas where PCB Bulk Products and
         Building Material will be removed, will be remediated after performance of the Bulk
         Product/Building Material removal and will be protected by the contractor during the
         remediation activities. During removal of PCB Bulk Products and associated Building
         Material, ground surfaces in the regulated area will be covered with 2 layers of 6 mu
         polyethylene sheeting to capture/collect any debris generated, and secured to prevent
         movement. The sheeting will extend a minimum of ten feet beyond the building area to be
         remediated.
       • Any building openings such as windows, doors, vents, etc in the immediate vicinity of the
         exterior remediation areas will be sealed off with critical barriers consisting of a minimum of
         one (I) layer of six (6) mil polyethylene sheeting securing the edges with tape.

     • Removal work practices within the regulated containment will be implemented which
       facilitate the removal of the PCB Bulk Product Waste and associated building material while
       also limiting the amount of dust and debris to be generated. The contractor will remove six
       (6) inches and/or twelve (12) inches of adjacent building material substrate around the PCB
       Bulk Product Waste as required.
     • All Building Materials removed during the remediation will be wrapped in poiy sheeting and
       transported to the waste storage area. The polv sheeting will be secured with tape to ensure
       that no dust is released during the transport and the contractor will be responsible for the
       remedliation of any new releases caused by spillage.
     • Verification sampling will be performed as described below to determine that all building
       materials, as outlined in this SIP, have been removed.

14      Cleanliness Verification

For interior and exterior containments, the entire area within containment will be HEPA vacuumed
to remove dust. The project monitor will then inspect the area to determine that is has been cleaned
of all dust generated during the abatement. For interior containments, two wipe samples will be
collected from horizontal areas where dust will accumulate within each containment. For exterior
containments, two wipe samples will be performed on horizontal building materials that were within
the containment.

For areas that are being renovated, where wipe samples are representative of materials to remain in
place, all wipe samples will be required to be <1.0 pg/IOO cm For areas that are being demolished
                                                            .

An estimated amount of cleanliness verification wipe samples is included in Table 5. However, the
actual number performed in the field will depend upon the number of containments established by
the Contractor for the abatement actions.

If any of the containment areas fail any of the cleanliness verification procedures, inspection or wipe
samples, the Contractor shall be instructed to re-clean the area and all inspections and testing will be
performed until the area has been cleared.

3.5       Verification Sampling

Approval of verification on a frequency less than that specified in Subpart 0 is requested for this
remediation project. Based on the existing sample data and this SIP for the project, the proposed
verification sampling frequency is one sample per every 50 linear feet of interface between building
caulks classified as PCB Bulk Product Waste and Building Material substrates that are porous
materials.

All verification samples from porous materials will be collected following the EPA Region I
Standard Operating Procedure which is included in Appendix D. Table 5 lists the areas where
samples will be collected for Federally-Regulated caulking and/or glazing compounds and the
estimated number of verification samples to be collected. Additionally, Table 5 lists the areas where
samples will be collected for Non-Federally Regulated caulking and/or glazing compounds and the
estimated number of venfication samples to be collected.

Additional details as to sampling protocols are as follows:

      •   At locations where PCB Bulk Product Wastes are bordered on either side by porous
          materials (e.g. concrete, brick, masonry) both sides of the removal action will be treated in
          the calculation of linear feet for verification sampling. If at all possible, verification
          samples on either side of the caulked joint will be staggered so as to “spread” the location
          of the verification samples.
      •    “Backing” material may be present behind the building caulks. Any backing material
          adjacent to the PCB containing caulking and/or glazing compounds and in contact/coated
          with a porous surface will be removed and disposed with the caulking and/or glazing
          compounds.
      •   No verification samples will be collected when the PCB Bulk Product Waste is classified as
          a glazing if the glazing is applied to two non-porous surfaces (e.g. glass and metal window
          frame). Paint on painted metal window frames will be considered to be a porous surface.
          However, no attempt will be made to segregate materials and the window, glazing, and
          frame will be totally removed. Thus, the metal frame would have limited the potential
          impact of PCBs and the building materials in contact with the metal frame will not be
          considered in the determination of linear feet for verification sampling.

The oversight contractor will collect verification samples at the approved frequency and will be
responsible for verifying that sufficient samples have been collected and that the remedial goal has
been achieved prior to initiation of “clean” demolition activities. Clean demolition activities will
commence after the oversight contractor has determined that remedial requirements have been
achieved. In the case where verification samples do not achieve the remedial goal, the oversight
contractor will instruct the remedial contractor to reestablish the appropriate controls and regulated
area and to continue the removal of Building Materials using the removal procedures as stated
above.

3.6     Soil Rernediation

Each of the soil remediation areas, east side of gymnasium wing, east side of carpentry wing, south side
of cafeteria wing, are easy to access with equipment that would be used in the remediation and it is
anticipated that each of the remediation areas will be performed at the same time.

An excavator or other simiar type of equipment will be used to remove soil which will be live loaded
into lined roll-off containers or dump trailers for transport to the appropriate disposal facthtv.
Verification samples will be collected as per Subpart 0 following excavation and analyzed as grab
samples. Any grab samples generated will be from contiguous sample locations on the 1.5 m by I .5m
Subpart 0 sampling grid. Soil samples collected from the base and sidewalls of the excavations will
consist of surficial soil.

Soil excavations will be backfiRed with certified clean soil meeting the CTDEP Remediation Standards
Regulations (RSRs) for the Residential Direct Exposure Criteria (RDEC) and Groundwater
Classification B (GB) Pollutant Mobility Criteria (PMC).

3.7     Waste Characterization, Transport, and
        Disposal

Wastes will be pre-characterized to the satisfaction of the selected disposal facility prior to initiating
any remedial activities. All wastes generated during building remediation activities will be shipped
for disposal as PCB Bulk Product Waste at a TSCA-permitted facility and no attempt will be made
to segregate the removed material.

All wastes generated during soil remediation activities will be shipped for disposal as PCB
Remediation Wastes at a concentration less than fifty (50) PPM at a facility permitted to receive such
waste. It is anticipated that approximately fifty one (51) cubic yards of soil will be disposed in this
manner.

3.8      Equipment Decontamination
All moveabie equipment, tools, and sampling equipment which has contacted the PCB Bulk Product
or Remediation Wastes will be decontaminated prior to leaving the site. Decontamination procedures
will comply with either 76l.79(b)(3)(i)(A), 76l.79(b)(3)(ii)(A) or 76l.79(c)(2).

All decontamination wastes, PPE, and polyethylene that come in contact with PCB Bulk Product or
Remediation Wastes will be disposed of as PCB Wastes with concentrations greater than 50 PPM.
These wastes will be segregated as to matrix, aqueous, non-aqueous liquids, or solid materials (e.g.,
PPE), and stored in drums or lined containers prior to transport from the site for disposal.

Aqueous and non-aqueous liquids will be tested for PCB content and shipped offsite for disposal at
permitted facility to receive such wastes. Solid Wastes will be containerized with the other regulated
PCB wastes generated during the remediation project for transport and disposal.

39      Notification and Certification
The removal and abatement measures described within this SIP will be initiated after receiving written
approval of the plan from EPA. Notification of intent to perform these remedial measures is provided
to EPA with this submittal and will also be provided to the CT DEP and school and local officials.

Also enclosed with this submittal, in accordance with EPA 40 CFR 761.61(a) (3), is a written
certification from CT DPW, indicating the location of all reports detailing sample collection and
analysis procedures used to assess or characterize the PCB contamination for this SIP are available for
EPA inspection.

Notes:   For glazing compounds,           is assumed   that   the window and/or door glass and window and/or door frame    will be   removed and there   will be   no porous building materials remaining   that   are in contact   with   the glazing.   Thus,   no verification sampling
           will be   performed in relation to glazing compounds.

                        Non-Federally Regulated
PCB-Containing Building Materials Scope of Work
The location of those materials classified as Excluded PCB Products with total PCB concentrations
1 PPM and <50 PPM based upon sample results of homogenous material are shown on figures
3A-D -and sample results for the caulking and/or glazing compounds are found in Table 1.

All caulking and/or glazing compounds containing 1 PPM and <50 PPM shall be removed
without the removal of associated adjacent porous building substrates to start utilizing the same
engineering controls described for interior and exterior removals within this document. Following
the removal of these caulking and/or glazing compounds; the following actions will be performed:

   •   Verification samples of adjacent porous building material substrates will be collected at a
       frequency of I per every 50 linear feet of homogenous caulk or glazing removed.
   •   If the verification sample is <1 PPM then no further action will be performed.
   •   If the verification sample is 1 PPM then one of the following two actions will be
       performed:
            o Six-inches of building materials will be removed from either side of the caulk for
               areas that are within the demolition/renovation area of the project.
            o Building materials will be encapsulated using materials and procedures that conform
               to the attachment included in this appendix.

Emmet O’Brien Te h School will commence a demolition and renovation
program starting or/’ sert date During this program there will be removal of asbestos
containing materia1, PC -contaminated building materials, and PCB-contaminated soil
previously identified at the school.

The asbestos and PCB abatement programs were authorized by the State of Connecticut
Departments of Public Health (CT DPH) and Environmental Protection (CT DEP) and
the United States Environmental Protection Agency Region I (EPA) after careful planning
and thorough review.

It is anticipated that workers and students will use the Emmett O’Brien Technical High
School buildings while removal and abatement is ongoing. To prevent exposure of these
persons to contaminated dust, Control Areas will be established outside of the Regulated/
Containment/Soil Excavation Areas. Only properly trained personnel associated with the
removal, abatement, and soil excavation actions will be allowed within the Control Areas
that will be established by placing barriers with signs indicating that access to the area is
restricted. Oversight will be provided to prevent unauthorized persons from entering these
restricted areas.

The asbestos and PCB abatement work will be performed by a Connecticut Department of
Public Health licensed asbestos abatement contractor and eüieI-e*p€rienc in the
handling of PCB and Asbestos contaminated materials, nsert contractor name    Asbestos
and PCB abatement work will be monitored continuously by Fuss & O’Neill
EnviroScience, LLC, an independent environmental consultant hired by the State to
conduct air testing during asbestos and PCB abatement activities.

As required by the CT DPH, CT DEP and EPA, this notification is being sent to parents,
teachers, and employee organizations at Emmett O’Brien Technical High School. Any
questions about the project may be directed to Mr. Richard Cavaliaro, Principal, Emmett
O’Brien Technical High School at (203) 238-6268 or Richard.Cavallaroct.gov.

We appreciate your patience and understanding during this process.

Sincerely,


Richard Cavallaro

                           Standard Operating Procedure for Sampling Concrete in the Field

  1.0     Scope and Application

         The following Standard Operating Procedure (SOP) describes a concrete sampling technique
                                                                                                            which uses
         an impact hammer drill to generate a uniform, finely ground, powder which is easily homogenized,
         extracted and analyzed. This procedure is primarily geared at providing enough sample for one or
                                                                                                                 two
         different analyses at a time. That is, the time required to generate sufficient sample for a full
                                                                                                            sweet of
         analyses may be impractical. The concrete powder is suitable for all types of environmental
                                                                                                           analyses,
         with the exception of volatile compounds, and may be analyzed in the field or at a fixed laboratory.
                                                                                                                  This
         procedure is applicable for the collection of samples from concrete floors, walls, and ceilings.

         The impact hammer drill is far less labor intensive than previous techniques using coring devices,
                                                                                                               or
         hammers and chisels. It allows for easy selection of sample location and sample depth. Not only
                                                                                                               can the
         project planner control the depth to sample into the cOncrete, from surface samples (0 ‘/ inch)
                                                                                                            down to a
         core of the entire slab, but the technique can also be modified to collect samples at discrete depths
                                                                                                                within
         the concrete slab.

        Another issue with concrete sampling is the fact that the amount of time spent drilling translates
                                                                                                           into the
         weight of sample produced. Thus, to maximize sampling time, it is important to know the minimum
        amount of sample required for each analysis. To do this, the project planner should take the following
        steps: I) Use the Data Quality Objective (DQO) process and familiarity with the site to develo
                                                                                                         pthe
        objectives of the sampling project and the depth(s) of sample to be collected. 2) Review the site
                                                                                                           history
        and any previous data collected to determined possible contaminants of concern. 3) Establish the
                                                                                                            action
        levels for those possible contaminants and determine the appropriate analytical methods (both
                                                                                                        field
        and/or fixed laboratory) to meet the DQOs of the project. 4) Based on the detection limits of
                                                                                                       these
        methods, determine the amount of sample required for each analysis and the total sample weight
                                                                                                           require
        for each sample location (including quality control samples).

        As with any environmental data collection project, all aspects of a concrete sampling episode should
                                                                                                              be
        well thought out, prior to going out in the field, and thoroughly described in a Quality Assurance
                                                                                                           Project
        Plan (QAPP). The QAPP should clearly state the DQOs of the project and document a complete
                                                                                                           Quality

                                                                                                          For more

2.0     Method Summary

        A one-inch diameter carbide drill bit is used in a rotary impact hammer drill to generate a fine concrete
        powder suitable foranalysis. The powder is placed in a sample container and homogenized for
                                                                                                           field or
        fixed laboratory analysis, The procedure can be used to sample a single depth into the concrete,
                                                                                                            or may
        be modified to sample the concrete at distinctly different depth zones. The modified depth sampling
        procedure is designed to minimize any cross contamination between the sampling zones.

                                                                                                               is
           generated during the drilling process. Proper respiratory protection and/or a dust control system
                                                                                                             must be
           in place at all times during sampling.

 4.0       Interferences and Potential Problems

          Since this sampling technique produces a finely ground uniform powder, physical matrix effects from
          variations in the sample consistency (i.e., particle size, uniformity, homogeneity, and surface condition)
          are minimized. Matrix spike analysis of a sample is highly recommended to monitor for any matrix
          related interferences.

          As stated in Section 1.0 above, this sampling procedure is not recommended for volatile organic
          compound (VOC) analysis. The combination of heat generated during drilling and the exposure
                                                                                                          of a
          large amount of surface area will greatly reduce VOC recovery. If low boiling point semi-volatile
          compounds (i.e., naphthalene) are being analyzed, then the drill speed should be reduced to minimize
          heat build-up.

 6.0     Sample Containers, Preservation, and Storage

        Concrete samples must be collected in glass containers for organic analyses, and may be collected in
        either glass or plastic containers for inorganic analyses In general, a 2-ounce sample container with
        Teflon-lined cap (wide-mouth jars are preferred) will hold sufficient volume for most analyses. A 2-
        ounce jar can hold roughly 90 grams sample. Note, samples which require duplicate and/or matrix
        spike/matrix spike duplicate analyses may require a larger sample container, or additional 2-ounce
        sample containers.

        Organic samples are to be shipped on ice and maintained at 4°C (± 2°C) until the time of extraction and
        analysis. Inorganic samples may be shipped and stored at room temperature. Refer to 40 CFR Part 136
        for guidelines on analysis holding times.

        To maintain sample integrity, chain-of-custody procedures must be implemented at the time of sampling
        to 1) document all sample locations and associated field sample identification numbers, 2) document all
        quality control samples taken, including field duplicates, split samples for confirmatory analyses, and PE
        samples, and 3) document the transfer of field samples from field sampler to field chemist or fixed
        laboratory.

7.0     Procedure

7.1     Single Depth Concrete Sampling

        Lock a 1-inch diameter carbide drill bit into the impact hammer drill and plug the drill into an
       appropriate power source. (A gasoline generator will be needed if electricity is not available.) For easy
        identification, sample locations may be pre-marked using a crayon or a non-contaminating spray paint.
       (Note, the actual drilling point must not be marked.) Depending on the appearance of the sample
        location, or the objectives of the sampling project, it may be desired to wipe the concrete surface with a
       clean dry cloth prior to drilling. All sampling decisions of this nature should be noted in the sampling
       logbook. Begin drilling in the designated lOcation. Apply steady even pressure and let the drill do the
       work. Applying too much pressure will generate excessive heat and dull the drill bit prematurely. The
       drill will provide a finely ground concrete powder that can be easily collected, homogenized and
       analyzed. Having several decontaminated impact drill bits on hand will help expedite sampling when
       numerous sample locations are to be drilled.

       Sample Collection

       A /2-inch deep hole (using a 1-inch diameter drill bit) generates about 10 grams of concrete powder.
       Based on this and the action levels for the project, determine the sampling depth, and/or the number of
       sample holes to be composited, to generate sufficient sample volume for all of the required analyses.
       (Note, with the absorbency of concrete, a !/2-inch deep hole can be considered a surface sample.)

       A decontaminated stainless steel scoopula can be used to collect the sample. The powder can either
                                                                                                                be
       collected directly from the surface of the concrete and/or the concrete powder can be scraped back into
       the hole and the less rounded back edge of the scoopula can be used to collect the sample. For holes
       greater than 2-inches in depth, a stainless steel spoonula will make it easier to collect the sample from the
       bottom of the hole.
                                                                                    SOP: Concrete Sampling
                                                                                    Rev, #:   0.0
                                                                                    Date:       12/01197
                                                                                    Page:       6of12
       To ensure collection of a representative sample when multiple analyses are required, a concrete sample
       should always be collected and homogenized in a single container and then divided up into the individual
       containers for the various analyses or split samples. This is particularly important when sample holes are
       deep, or when several holes are drilled adjacent to each other to form a sample composite.

       Wall and Ceiling Sampling

       A team of two samplers will be required for wall and ceiling sampling. The second person will be
       needed to hold a clean catch surface (i.e., an aluminum pan) below the drill tocollect the falling powder.
       For wall samples, a scoopula, or spoonula, can be used to collect remaining concrete powder from within
       the hole. For ceiling holes, it may be necessary to drill the hole at an angle so the concrete powder can
       fall freely in the collection plan (and avoid falling on the drill). Another alternative might be to use the
       chuck-end of the drill bit and punch a hole through the center of the collection pan. The drill bit is then
       mounted :through the pan and into the drill, Thus, the driller can be drilling straight up while the assistant
       steadies the pan to catch the falling dust. As a precaution, it may be advantageous to tape a piece of
       plastic around the drill, just below the chuck, to avoid dust contaminating the body of the drill and
       entering the mechanical vents. (Note, the plastic should deflect dust from the drill, but be loose enough
       underneath to allow for proper ventilation.)

7.2    Multiple Depth Concrete Sampling

      The above method for concrete sampling can also be used to collect samples from different depths within
      the concrete. To do this, two different sized drill bits (i.e., ‘/2 inch and 1 inch) and a simple vacuum pump
      with a vacuum trap assembly is required (see Figure 1). First, the 1 inch drill bit is used to drill to the
      first level and the concrete sample is collected as described in Section 7.1. The vacuum pump is then
      turned on and the hole is cleaned out using the vacuum trap assembly. The drill bit is then changed to the
      ‘/2 inch bit and the next depth is drilled out (the ‘/2 inch bit is used to avoid contact with
                                                                                                     the sides of the
      first hole). A clean tube or flask is placed on the vacuum trap, and the sample from the second drilling is
      collected. To go further, the 1 inch drill is usedto open up the hole to the second level, the hole is
      cleared, and then the 1/2 inch drill is used again to go to a third level, etc. Note, the holes and concrete
      surface should be vacuumed thoroughly to minimize any cross-contamination between sample depths.

      Vacuum Trap Design and Clean-out

       The trap presented in Figure 1 is a convenient and thorough way for collecting and removing concrete
       powder from drilled holes. The trap system is designed to allow for control of the suction from the
      vacuum pump and easy trap clean-out between samples. Note, by placing a hole in the inlet tube (see
      Figure 1), a finger on the hand holding the trap can be used to control the ‘suction at the sampling tip.
      Thus, when this hole is left completely open, there will be no suction, andthe sampler can have complete
      control over where and what to sample. To change-out between samples the following steps should be
      taken: 1) The pasture pipet and piece of polyethylene tubing at the sample inlet should be replaced with
      new materials, 2) the portion of the rubber stopper and glass tubing that was in the trap should be wiped
      down with a clean damp paper towel (wetted with deionized water) and then dried with a fresh paper
      towel, 3) a clean pipe cleaner should be drawn through the glass inlet tube to remove any concrete dust
      present, and 4) the glass tube or flask used to collect the sample should swapped out with a clean
      decontaminated sample trap. Having several clean tubes or flasks on hand will facilitate change-out
      between samples.

7.3   Decontamination Procedure

      Necessary supplies for decontamination include: two small buckets, a scrub brush, potable water,
      deionized water, a squirt bottle for the deionized water, and paper towels. The first bucket contains a
      soap and potable water solution, and the second bucket contains just potable water. Place all used drill
      bits and utensils in the soap and water bucket. Scrub each piece thoroughly using the scrub brush. Note,
      the concrete powder does cling to the metal surfaces, so care should be taken during this step, especially
      with the twists and curves of the drill bits Next rinse each piece in the potable water bucket, and follow
      with a deionized waterrinse from the squirt bottle. Place the deionized.water rinsed pieces oh clean
      paper towels and individually dry and inspect each piece. Note, all pieces should be dry prior to reuse.


8.0   Field Documentation

      All Site related documentation and reports generated from concrete sampling should be maintained in the
      central Site file. If personal logbooks are used, legible copies of all pertinent pages must be placed in the
      Site file.
                                                                                   SOP: Concrete Sampling

                                                                                   Date:     12/01/97
                                                                                   Page:     8of12

8.1     Field Logbooks

        All field documentation should be maintained in bound logbooks with numbered pages. If loose-leaf
        logsheets are used to document site activities, extra care should be taken in keep track of all logsheets.
        The original copy ofall logsheets should be maintained in the central Site file. Note, all sample locations
        must be documented by tying in their location to a detailed site map, or by using two or more permanent
        landmarks. The following information should be documented in the field logbooks:

        •   Site name and location,
        •   EPA Site Manager,
        •   Name and affiliation of field samplers (EPA, Contractor company name, etc.),
            Sampling date,
        •   Sample locations and IDs,
        •   Sampling times and depths, and
        •   Other pertinent information or comments

8.2     Sample Labeling and Chain-of-Custody

8.2.1       Samile Labels

            Sample labels willbe affixed to all sample containers. Labels must contain the following
            information:

            •   Project name,
            •   Sample number, and/or location
            •   Date and time of sampling,
            •   Analysis,
                Preservation, and
            •   Sampler’s name.

8,2.2       Chain-of-Custody

            All samples must be traced from collection, to shipment, to laboratory receipt and laboratory custody.
            The Chain-of-Custody (COC) Record is a multi-part form that is initiated as samples are acquired
            and accompanies a sample (or group of samples) as they are transferred from person to person. The
            COC form is signed by all individuals responsible for sampling, sample transport, and laboratory
            receipt. (Note, overnight deliver services, often used with sample transport, are exempt from having
            to sign the COC form. However, copies of all shipping invoices must be kept with the COC
            documentation.) One copy of the COC is retained by the field sampling crew, while the original (top,
            signed copy) and remaining carbonless copies are placed in a zip-lock bag and taped to the inside lid
            of the shipping cooler. If multiple coolers are required for a sample shipment to a single laboratory,
            the COC need only be sent with one of the coolers. The COC should state how many coolers are
            included with the shipment. All sample shipments to different laboratories require individual COC
            forms. The original COC form accompanies the samples until the project is complete, and is then
            kept in the permanent project file. A copy of the COC is also kept with the project manager, the
            laboratory manager, and attached to the data package.
                                                                                       SOP: Concrete Sampling

8.2.3        Custody Seal

             The Custody seal is an adhesive-backed label which is also part of the chain-of-custody process. The
             custody seal is used to prevent tampering with the samples after they have been collected in the field
             and sealed in coolers for transit to the laboratory. The Custody seals are signed and dated by a
             sampler and affixed across the opening edges of each cooler containing samples. Clear packing tape
             should be wrapped around the cooler, and over the Custody seal, to secure the cooler and avoid
             accidental tampering with the Custody seal.

9.0     Quality Assurance and Quality Control (QA/QC)

        A solid QA/QC program is essential to establishing the quality of the data generated so that proper
        project decisions can be made. The following are key quality’ control elements which .should be
        incorporated into a concrete sampling and analytical program.

9.1     Equipment Blanks

        An equipment blank should be performed on decontaminated drill bits and collection utensils at a
        frequency of I per 20 samples or I per day, whichever is greater. To prepare the equipment blank, place
        the decontaminated drill bit and utensils in a large clean stainless steel bowl. Pour sufficient deionized
        water into the bowl to fill all of the required sample containers. Next, stir the drill bit and utensils in the
        bowl with a clean utensil to thoroughly mix the blank. Finally, decant off the equipment blank into the
        sample containers. Note, a clean funnel may help to pour off the equipment blank into the containers.

9.2     Field Duplicates

        Field duplicates are samples collected adjacent to each other (collocated) at the same sample location
        (not two aliquots of the same sample). Field duplicates not only help provide an indicator of overall
        precision, but measure the cumulative effects of both the field and analytical precision, and also measure
        the representativeness of the sample. Field duplicates must be prepared and analyzed at a frequency of I
        per 20 samples or I per non-related concrete matrix, whichever is greater. An example o.f a non-related
        concrete matrix.might be the investigation of two different types of chemical spills.

        Calculate the Relative Percent Difference (RPD) between the sample and its duplicate using Equation 1.

        Equation 1

          The following general guidelines have been established for field duplicate criteria:

          a   If both the original and field duplicate values are practical quantitation limit (PQL), then the
              control limit for RPD is 50%,
          •   If one or both values are <PQL, then do not assess the RPD,

          If more rigorous field duplicate criteria are needed to achieve project DQOs, then that criteria should be
          documented in the project QAPP.

       If the field duplicate criteria specified above are not met, then flag that target element with an “n” on the
       final report for both the original and field duplicate samples. Report both the original and field duplicate
       analyses; do not report the average. Field duplicate samples should should be indicated on the sample
       ID. For example, the sample ID can contain the the suffix “FD”,

9.3    Laboratory Duplicates

      Laboratory duplicates are two aliquots of the same sample that are prepared, homogenized and analyzed
      in the same manner. (Note, proper sample homogenization is critical in producing meaningful results.)
      The precision of the sample preparation and analytical methods is determined by performing a laboratory
      duplicate analysis. Laboratory duplicates can be prepared in the field and submitted as blind samples, or
      the laboratory can be requested to perform the laboratory duplicate analysis. In the case of laboratory
      prepared duplicates, the field sampling team must be sure to provide sufficient sample volume.
      Laboratory duplicates must be prepared and analyzed at a frequency of 1 per 20 samples or I per non-
      related concrete matrix, whichever is greater.

      Calculate the RPD between the sample and its duplicate using Equation 1. The following general
      guidelines have been established for laboratory duplicate criteria:

      •       If both the original and laboratory duplicate values are PQL, then the control limit for RPD is
                25%,
      •       If one or both values are <PQL, then do not assess the RPD.

      If duplicate criteria are not met, then flag that target element with an on the final report for both the
                                                                               ““


      original and duplicate samples. Report both the original and duplicate analyses; do not report the
      average.

9.4   Matrix Spike/Matrix Spike Duplicate Samples

      Matrix spike/matrix spike duplicate samples (MS/MSDs) are two additional aliquots of a sample which
      are spiked with the appropriate compound(s) or analyte(s) of concern and then prepared and analyzed
      along with the original sample. (Note, proper sample homogenization, prior to spiking, is critical iii
      producing meaningful results) MS/MSDs help evaluate the effects of sample matrix on the analytical
      methods being used. The field sampling team must provide sufficient sample volume such that the field
      or fixed laboratory can prepare and analyze MS/MSDs at a frequency of I per 20 samples or I per non-
      related concrete matrix, whichever is greater.
                                                                                  SOP: Concrete Sampling

9.5   Performance Evaluation Samples

      In accordance with the EPA Region I Performance Evaluation Program Guidance, performance
      evaluation (PE) samples should be submitted for each type of analysis to be performed in the field or by
      the fixed laboratory performing full protocol EPA methods. PE samples provide information on the
      quality of the individual data packages PE samples are certified standard reference materials (SRMs)
      from a source other than that used to calibrate the instrument. If both field and fixed laboratories are
      being used to analyze samples, at least one solid PE sample should undergo both field analysis and
      confirmatory full protocol EPA method analysis to facilitate data comparability A copy of the certified
      values for the SRM must be submitted with the final data packages to facilitate data evaluation.

9.6   Data Verification and Validation

      All field data and supporting information (including chain-of-custody) that is collected during a concrete
      sampling episode should be verified daily, by a person other than that performing the work, to check for
      possible errors.
                                                                                        SOP: Concrete Sampling

         During the project planning process, a plan for data validation should be established for all
                                                                                                          data, both for
         field and fixed laboratories. All data must be validated to assure that it is of a quality suitable
                                                                                                             to make

On February 12, 13 and 17, 2010, and March 6, 2010 TRC of Windsor, Connecticut conducted a
preliminary investigative survey for polychiorinated biphenyl (PCB) presence at the Emmett O’Brien
Technical High School, located at 141 Prindle Avenue in Ansonia, Connecticut. The investigation
was initiated at the request of the Connecticut Technical High School System (CTHSS), following
the EPA’s publication of preliminary guidance on managing PCB caulk in schools in September
2009, in an effort to proactively protect the health and safety of the Technical High School System’s
students and staff from potential PCB exposure. The scope and strategy of the inspection was
devised with ongoing consultation between CTHSS, TRC and EPA, and did not include building
spaces/wings constructed or completely renovated post 1980 (after the federal ban on the use ofPCB
in 1979). Bulk sampling of interior/exterior caulks/glazes was conducted, with the focus of the
investigation borne upon the building envelope spaces (exterior walls, expansion joints, doors,
windows, etc), and the general locations of the differing types of caulks/glazes was noted. After
receiving laboratory results on the bulk samples, a targeted program of both interior surface dust
sampling and indoor air sampling was conducted. Neither soil nor building substrate sampling were
included as part of the initial investigative program.


TRC conducted the bulk caulk/glaze inspection, generally modeling the inspection protocols after the
EPA AHERA asbestos inspection protocols. A visual assessment of the areas was perfonned to
identify differing caulks/glazes present, and a single grab bulk sample of each type ofhomogeneous
caulk/glaze identified was collected, with samples collected down to the substrate/backer to ensure
no evidence of prior older caulk/glaze was present, therefore verifying the samples collected
represented a distinct homogeneous material. Following sample collection, replacement caulking
material was installed to seal the sample location. Samples were submitted following chain of
custody procedures to Complete Environmental Testing, Inc. in Stratford, Connecticut for analysis
via EPA Methods 3540C/8082 (PCB Arochior with Soxhlet Extraction). Analytical results indicated
interior and exterior caulks/glazes defined as EPA PCB Bulk Products (50ppm), as well as further
caulks/glazes subject to regulation by the CTDEP (>1 ppm <5oppm), were present. Detailed results
 of the bulk caulk/glaze sampling can be found in Table 1 and Appendix A, while the bulk sample
 locations and the general locations ofthe EPA & CTDEP regulated caulk/glaze can be found on the
 drawings/field sketches in Appendix D.


Following receipt of the bulk caulk/glaze analytical results, interior dust wipe sampling was
conducted by TRC. A targeted sampling strategy, discussed with and approved by the EPA, was
implemented, wherein two samples each were collected from five rooms which contained the
 greatest caulk/glaze PCB source strength, as well as from the cafeterias and break rooms where food
consumption takes place (representing the highest potential for exposure via ingestion). In each
room one sample was collected from an area of high contact probability (e.g. desk top) and one
sample was collected from an area ofhigh potential dust accumulation (e.g. window sill). Sampling
media was laboratory prepared and consisted of a gauze pad pre-moistened with hexane. Samples
were collected using disposable 100 cm templates following the collection protocols outlined in
                                    2
EPA 40 CFR 761.123 and ASTM Method D661 -01. One field blank and one duplicate sample were
also collected for quality control (QC) purposes. Samples were submitted following chain ofcustocly
procedures to Con-Test Analytical Laboratory in East Longmeadow, Massachusetts for analysis via
EPA Methods 3540C/8082 (PCB Arochlor with Soxhiet Extraction). Analytical results indicated no
detectable levels of PCB in any of the dust wipes collected (well below the EPA/CTDEP/CTDPH
school guidance level of 1 .Oug/1 00cm Note, sample AW-09 was inadvertently spiked at the
                                  ).
                                  2
laboratory with arochlor solution 1016/1260, resulting in the subsequent detection of 0.51 ug of each
arochlor during analysis. This data is not representative of the actual field condition and was voided.
Note also, arochior 1254, the arochlor associated with the majority of the detectable bulk caulk
samples, was not detected in sample AW-09, which is consistent with the results of all other dust
wipe samples. Detailed results of the interior dust wipe sampling can be found in Table 2 and
Appendix B.


TRC also conducted targeted indoor air sampling following receipt ofthe bulk caulk/glaze analytical
data. A targeted sampling strategy, also discussed with and approved by the EPA, was implemented
which was based upon the protocols found in the US Green Building Council (USGBC) LEED 2009
for Schools Indoor Environmental Quality (IEQ) Indoor Air Quality (IAQ) sampling guidance.
            -




Samples were collected at a rate of at least one per 25,000 square feet of building space/floor area,
spaced representatively throughout the building to cover each floor, each wing, separate HVAC
system, and represent the various types of room spaces (gym, cafeteria, offices, classrooms, shops,
hallways, etc.). Sample locations were also biased with a targeted strategy toward the areas/rooms
which contained the greatest caulk/glaze PCB source strength, and included an air sample from each
room where dust wipe sampling was conducted for comparative/correlation purposes. Sampling
media consisted of laboratory prepared 20mm glass cartridges filled with polyurethane foam (PUF)
sorbent, and samples were collected from breathing zone elevations (3’       —   6’ above floor level)
following the collection protocols outlined in EPA Method TO-i OA. Sampling flow rates were
calibrated pre and post sampling using a field rotameter calibrated from a primary standard, with a
maximum flow rate of 5 liters per minute and a minimum sampling time of 4 hours, resulting in a
minimum sample volume of 1200 liters. One field blank, one blind spike, one duplicate, and one
ambient outdoor sample were also collected for quality control (QC) purposes. Collected samples
were submitted following chain of custody procedures to Northeast Analytical Labs in Schenectady,
New York for analysis via EPA Methods 3540C/680 (PCB Flomolog with Soxhiet Extraction).
Analytical results indicated no airborne levels of PCB above the EPA September 2009 guidance
level of 450ng/m for students/staff in high schools, in any of the indoor air samples collected.

Notes:
Investigation did not include building spaces/wings constructed post 1980 (after the federal ban on
the use of PCB in 1979). Bulk inspection scope included interior and exterior building envelope
spaces (exterior wails, expansion joints, windows, doors, etc.), sampling of each homogeneous
caulklglaze identified and identif’ing general locations for each homogeneous caulk/glaze sampled.
Dust wipe inspection scope included targeted sampling from areas with higher PCB content
caulk/glaze present and from areas with higher potential for exposure via ingestion (cafeteria, break
room). Air sampling scope included sampling from representative floors/building spaces following
LEED Indoor Environmental Quality (IEQ) sampling strategies, with a bias toward areas with higher
PCB content caulk/glaze present. Based on results of the preliminary investigation, sampling soil
and building substrates for PCB presence may be warranted.

             building material abutting exterior and/or interior window caulking compounds shown on
             the Contract Drawings and Site Remedial Plan shall be removed to a depth of at least six
             (6) inches of building materials on each side of the window systems.

             Non-federally regulated PCB-containing caulking and/or glazing compounds is defined
             as any building material manufactured with total PCB concentrations 1 mg/kg and < 50
             mg/kg. All non-federally regulated caulking and/or glazing compounds shall be removed
             from the site and disposed of per these Specifications by the Contractor.

             If total PCB concentrations in the building materials are >1 mg/kg and these building
             materials are to remain, then an encapsulant, per these Specifications, shall be applied by
             the Contractor to the area where the caulk and/or glazing were in contact with building
             materials are to remain. If total PCB concentrations in the building materials are >1
                                      .




             mg/kg and the building materials are to be removed, the contractor shall be required to
             remove six (6) inches of adjacent porous building materials. If total PCB concentrations in
             the remaining building materials are <1 mg/kg, then the building materials shall be left in
             place as is.

       (çC   Work in demolition and/or renovation areas, shall be scheduled during school vacations,
      çP     when school is not in session. Such work shall be started and completed within such
             schedule. Work shall be completed at least ten (10) days prior to students returning to
             school. Building materials in contact with the federally and non-federally regulated
             caulking and/or glazing compounds shall be appropriately cleaned by the Contractor as per
             these Specifications. Verification samples of the remaining, cleaned building materials
             shall then be taken by the Project Monitor.

             The Owner shall hire a PCB Engineer for the duration of the PCB abatement work. The
             PCB Engineer shall provide a Project Monitor to oversee the activities of the Contractor.
             After removal, verification sampling shall be performed by the Project Monitor. PCB Bulk
             Product Wastes and abutting building materials shall be considered removed when all
             verification samples are <1 mg/kg total PCBs.

             These Specifications govern all work activities that disturb PCB-containing caulk and
             glazing and associated building material. All activities shall be performed in accordance
             with, but not limited to, OSHA Regulation 29 CER 1926, EPA PCB Regulation 40 CFR

      Regulated Area shall be required to adhere to the requirements of personnel protection as stated in
      this section and all other applicable provisions of the Contract. All unqualified and unauthorized
      persons shall be escorted outside of the Regulated Area and if due to other provisions of the
      Contract, escorted outside of the project site during the PCB work.
3.4   PCB ABATEMENT PROCEDURES
      The Site Supervisor, acting as the OSHA Competent Person, shall be at the site at all times during
      the performance of abatement work.

      The Contractor shall not begin abatement work until authorized by the Project Monitor, following a
      pre-abatement visual inspection of each Regulated Area.

      All workers and authorized persons shall enter and leave the Regulated Area through the worker
      decontamination unit, leaving contaminated protective clothing in the airlock for disposal of as
      PCB contaminated waste. No one shall eat, drink, smoke, chew gum or tobacco, or apply cosmetics
      while in a Regulated Area.

      The following details the extent of each phase of operation designated for this work. Phase areas
      may be combined or divided at the direction of the PCB Engineer. Proceed through the sequencing
      of the work phases under the direction of the Engineer.

      See the PCB Site Remedial Plan and other Contract Drawings provided for the site for specific
      locations of PCB containing caulks and glazing. The specific locations for these materials and
      amount of associated building materials to be removed as well are indicated on these drawings and
      the PCB Site Remedial Plan.

      During removal, the Contractor shall spray PCB containing building material with water using
      airless spray equipment capable of providing a “mist” application to reduce airborne dust. Hose
      length shall be sufficient to reach all of the Regulated Area. Do not “flood” the area with hose type
      water supply equipment with the potential to create water releases from the regulated area.

      The Contractor shall employ mechanical methods such as cutting, grinding, and pneumatic
      hammers to remove PCB contaminated wastes. The methods employed must not damage the
      integrity of the containment structure and shall not create a breach through which contaminated
      dust may escape. The Contractor shall be responsible for all costs associated with decontamination
      and remediation in the case of a containment breach.

      In order to minimize PCB concentrations inside the Regulated Area, the Contractor shall remove
      the materials in manageable sections. In addition, PCB Waste materials removed from any elevated
      level shall be carefully lowered to the floor.

      The Contractor shall promptly place the PCB Waste material in disposal containers (six (6) mil
      polyethylene bags/ poly-lined dumpsters, etc.) as it is removed. Large components removed intact
      may be wrapped in one (1) layer of six (6) mil polyethylene sheeting secured with tape and glue. As
      the disposal containers are filled, the Contractor shall promptly seal the containers, apply caution
      labels and clean the containers before transportation to the airlock. Bags shall be securely sealed to
      prevent accidental opening and leakage by taping in gooseneck fashion. Small components and
      PCB Waste material with sharp-edged components (e.g. nails, screws, metal lath, tin sheeting)
                                                                        PROJECT NO. BI-RT-844(ASB)

                 ABATEMENT OF PCB CONTAMINATED BUILDING MATERIALS
                                                         Page 10 of 16

which could tear polyethylene bags and sheeting shall be placed in clean drums and sealed with
locking ring tops. Drums may not be placed intact into final waste disposal containers intact and
may be reused by the Contractor after the contents have been emptied. However, any drums use to
handle wastes must be broken down and disposed of properly with other PCB wastes.

All waste containers shall be leak-tight. Containers shall be decontaminated by wet cleaning and
HEPA vacuuming within the airlock prior to exiting the regulated area. Wet clean each container
thoroughly before moving to a Waste Holding Area.

If at any time during PCB Waste removal, the Project Monitor should suspect contamination of
areas outside the Regulated Area, the Contractor shall immediately stop all abatement work and
take steps to decontaminate these areas and eliminate causes of such contamination. Unprotected
individuals shall be prohibited from entering contaminated areas.

After completion of abatement work; all surfaces from which PCB Waste has been removed shall
be wet brushed, using a nylon brush, wet wiped and sponged or cleaned by an equivalent method to
remove all visible material (wire brushes are not permitted). Cleaning shall also include the use of
HEPA filtered vacuum equipment.

The Contractor shall also remove and containerize all visible accumulations of PCB Waste and/or
PCB contaminated debris which may have splattered or collected on the polyethylene engineering
controls/barriers.

The Contractor shall clean surfaces of contaminated containers and equipment thoroughly by
vacuuming with HEPA filtered equipment and wet sponging or wiping before moving such items
into the airlock for final cleaning and removal to uncontaminated areas.

The Contractor shall remove contamination from the exteriors of the air filtration devices,
scaffolding, ladders, extension cords, hoses and other equipment inside the Regulated Area.
Cleaning may be accomplished by brushing, HEPA vacuuming and/or wet cleaning. The Contractor
shall wet wipe the Regulated Area beginning at the point farthest away from the negative air
filtration units using cotton rags or lint free paper towels. Rags and towels shall be disposed of after
each use. Workers should avoid the use of dirty rags to insure proper cleaning of surfaces. Mop the
entire floor with a clean mop head and amended. Water shall be changed frequently

Once the Regulated Area surfaces have dried, the Project Monitor shall perform a thorough post
abatement visual inspection. The Project Monitor will visually inspect the Regulated Area and the
surrounding Control Area to determine that the Contractor has sufficiently decontaminated and
removed any dust that might contain PCBs. All surfaces within the Regulated Area, including but
not limited to ledges, beams, and hidden locations shall be inspected for visible residue. Evidence
of dust contamination that would be indicative of PCB contamination identified during this
inspection will necessitate further cleaning as heretofore specified. The area shall be re-cleaned at
the Contractor’s expense, until the standard of cleaning is achieved.

Once the area has received a satisfactory post-abatement visual inspection, any equipment, tools or
materials not required for completion of the work, shall be removed by the Contractor from the
Regulated Area. Negative air filtration devices shall remain in place and operating for the
remainder of the clean-up operation.



                                                                   PROJECT NO. BI-RT.844(ASB)

3.5   PHASED PCB ABATEMENT PROCEDURES
      Should the potential exist for an unsafe condition to be produced by removing PCB contaminated
      building materials prior to removing clean materials, then the Contractor shall notify the Owner and
      the PCB Engineer and Project Monitor of such concerns and mitigate potentially unsafe conditions.

      Should PCB contaminated building material need to remain to prevent an unsafe situation, the PCB
      Engineer shall collect the required verification samples prior to the performance of any demolition
      in the area. The Contractor shall then physically demark the line of clean building materials as
      determined by the verification sampling on the structure by painting or otherwise marking the
      structure so that it is clearly visible.

      Once the area is marked, the Contractor may remove clean building materials as described
      elsewhere in the Contract Document. After the clean building materials have been removed to the
      marked line, PCB Contaminated building materials shall be abated according to the procedures
      stated in section 3.4 of this specification.
3.6   POST-ABATEMENT RE-OCCUPANCY PROCEDURES
      The Project Monitor shall collect verification samples as per the EPA Region 1 Standard Operating
      Procedure for Sampling Concrete at the frequency specified in the approved PCB Site Remedial
      Plan. The verification samples will be analyzed for PCBs using EPA Methods 3540 and 8082.
      Analysis of verification samples will be expedited but the Contractor shall expect 48 to 72 hours
      (these hours do not include weekend and/or holiday hours) delay until analytical results are
      available. Analysis of wipe verification sampling will be expedited but the Contractor shall expect
      and 48 to 72 hours (these hours do not include weekend and/or holiday hours) delay until analytical
      results are available. Asbestos air clearance sampling, if required, will be conducted along side
      wipe verification sampling and analyzed within the 48 to 72 hour period of wipe sample analysis.

      Federally Regulated PCB Waste:: In areas where PCB Wastes have been removed along with the
      associated building materials as required, the remedial standard to be achieved by all verification
      samples is <1 mg/kg total PCBs. If this standard is achieved then additional re-occupancy work
      (asbestos re-occupancy air sampling and wipe verification sampling) will be performed. If the
      remedial standard is exceeded, the Contractor shall be instructed to remove additional building
      materials as instructed by the Project Monitor.
      4
      Non-federally Regulated PCB Waste: Work involving non-federally regulated PCB waste shall be
      removed and the associated building materials removed and cleaned in accordance with these
      Specifications and left in place. The remedial standard to be achieved by the verification samples
      collected from the associated building materials is <1 mg/kg total PCBs. if this standard is achieved
      and the building materials are to be left in place, then additional re-occupancy work (asbestos re
      occupancy air sampling and wipe verification sampling) will be performed. if this standard is not
      achieved and the building materials are to be left in place, then an encapsulant shall be applied by
      the Contractor to the area where the caulk and glazing were in contact with building materials and
      after the encapsulant has cured, new caulk or glazing shall be applied by the Contractor. If this
      standard is not achieved and the building materials are to be removed, the Contractor shall remove
      additional building materials as instructed by the Project Monitor.

      Following the collection and analysis of verification samples indicating that remediation goals have
      been achieved or the encapsulation of other materials, the Project Monitor shall collect wipe
      samples of surfaces within the Containment Area to determine if the decontamination performed by
      the Contractor has been sufficient to remove potentially PCB containing dust. The PCB Engineer
                                                                        PROJECT NO. BI-RT-844(ASB)
                                                          SECTION 02 82 19
                       ABATEMENT OF PCB CONTAMINATED BUILDING MATERIALS
                                                               Page 12 of 16

      shall obtain expedited analyses of these samples from an outside laboratory, but the Contractor shall
      expect 48 to 72 hours (these hours do not include weekend and/or holiday hours) delay until
      analytical results are available. The PCB Engineer shall instruct the Contractor to perform
      additional decontamination if wipe sample results are 1 .0 p.gIlOO cm2. Areas which do not comply
      shall continue to be cleaned by and at the Contractors expense, until the specified Standard of
      Cleaning is achieved as evidenced by results of wipe testing. When the Regulated Area passes the
      re-occupancy clearance, controls established by these Specifications may be removed.

      The Contractor shall be aware that some PCB containing materials also contain regulated
      concentrations of asbestos. Asbestos air clearance sampling shall be performed along side wipe
      verification sampling within each containment if required.

      Wipe sampling will not begin until after the area has received an acceptable post abatement visual
      inspection and verification sample results indicate compliance with remedial standards.

      Analysis shall follow the requirements of EPA Methods 3540 and 8082.

      Each homogeneous Regulated Area which does not meet the clearance criteria shall be thoroughly
      re-cleaned using FIEPA vacuuming and/or wet cleaning, with the negative pressure ventilation
      system in operation. New samples shall be collected in the Regulated Area. The process shall be
      repeated until the Regulated Area passes the test, with the cost of repeat sampling being borne
      entirely by the Contractor.

      For a PCB Waste abatement project with more than one homogeneous Regulated Area, the release
      criterion shall be applied independently to each Regulated Area.

      These clearance sampling procedures shall be implemented for both interior and exterior NPE work
      areas.
3.7   Post Abatement Work Area Deregulation
      The Contractor shall remove all remaining polyethylene, including critical barriers, and airlocks
      with the negative air filtration devices in operation. HEPA vacuum and/or wet wipe any visible
      residue which is uncovered during this process. All waste generated during this disassembly
      process shall be discarded as PCB Bulk Product Waste.

      A final visual inspection of the work area shall be conducted by the PCB Engineer and the Project
      Monitor to ensure that all visible accumulations of PCB Waste materials have been removed and
      that no equipment or materials associated with the abatement work remain.

      The Contractor shall restore all work areas and auxiliary areas utilized during work to conditions
      equal to or better than original. Any damage caused during the performance of the work activity
      shall be repaired by the Contractor at no additional expense to the Owner.
3.8   Encapsulation Procedures
      The contractor shall encapsulate building materials located in areas where renovation/demolition is
      not being performed as indicated on the Contract Drawings and these Specifications with an
      elastomeric, crack bridging, anti-carbonation, protective coating to be applied as the encapsulant.
      Following completion of encapsulant application, including cure time, the Contractor shall reinstall
      caulk as per and meeting the specifications contained within Section 079200   —   Joint Sealants.


                                                                        PROJECT NO. BI-RT-844(ASB)

3.1   SITE PREPARATION
            Prior to performing soil excavations, the Contractor shall secure the excavation
            area with temporary fencing. The Contractor may move temporary fencing
            sections to allow for work progress while actively working in an excavation area.
            However, if no work is actively being performed in an excavation area the
            temporary fencing will be reinstalled.

      A.    Excavation Layout

            The Contractor shall mark the limits of proposed initial excavations of
            contaminated soils prior to performing any excavations. The limits of the
            excavations shall correspond to those shown on the Contract Drawings and Site
            Remedial Plan

           The Contractor shall install in accordance with Section 02112, “Erosion and
           Sediment Control” and the Contract Drawings.

      C.   Waste Storage Areas

           If the Contractor chooses to store soil onsite prior to transport offsite for disposal,
           the Contractor shall construct a secured Waste Storage Area at a location agreed
           to by the Contractor and the PCB Engineer within contract limit lines. The
           contract limit lines are to be secured as described elsewhere in these
           specifications and entry shall be limited to Contractor Personnel only. The Waste
           Storage Area shall enclose all Suitable Waste Storage Containers actively in use
           with temporary fencing. The fence shall be marked with a Large ML mark as
           specified in 40 CFR Part 761 Subpart C.

      D.   Waste Storage

           The Contractor shall not store waste onsite in a Suitable Waste Container for a
           period of more than 30 days. The start of the period of waste storage for each
           container will start on the day in which wastes are first loaded into a container
           and will terminate when the container is transported offsite.

           The Contractor shall store waste onsite in Suitable Waste Containers. No
           stockpiling shall be allowed and the Contractor shall be responsible for all costs
           associated with investigation and remediation of any areas contaminated due to
           the failure of the Contractor to comply with waste storage requirements.

      E.   Decontamination

           The Contractor shall decontaminate all moveable equipment that contact PCB
           Remediation Wastes in accordance with the procedures specified in § 761.79(c).
           The Contractor shall not remove any equipment from the Contaminant Zone until
           it has been properly decontaminated. Specifically, the Contractor shall employ
           double wash/rinse procedures as specified in 40 CFR Part 761 Subpart S or swab
           non-porous surfaces that have contacted PCB wastes with a solvent as specified
           in §761.79(c)(2)(i). The Contractor shall segregate all liquid waste streams and
           be responsible for characterizing these wastes for disposal purposes. Solid wastes
           generated during decontamination shall be stored for disposal with the other PCB
           wastes generated during remediation activities.

           The PCB Engineer shall be responsible for ensuring that decontamination
           procedures are followed and that wastes are appropriately characterized and
           disposed of properly.
3.2   SURFACE PREPARATION
      A.   Clearing and Grubbing

           Clearing is not required for any of the excavation areas as this will be performed
           by others. Limited grubbing is required in the excavation to be performed on the
           northwest side of the A-Wing as there are some small bushes and associated
           roots in place within the excavation area.

                                                             PAGE 6 OF 9


           The soil removed from any root structure that has been grubbed from an
           excavation area must remain in the excavation or be placed directly into a
           Suitable Waste Container. Unless suitably decontaminated and tested as clean, all
           roots grubbed from an area must be considered to be PCB Remediation Wastes.

      B.   Lock Box and Carpentry Shop Debris

           Is the contractor responsible for moving lock box and carpentry debris located on
           the east side of the carpentry shop
3.3   EXCAVATION AND HANDLING OF CONTAMINATED SOILS
      A.   Contaminant Zone Operations

           Construction equipment such as excavators, front end loaders, dozers and hauling
           vehicles, used within a Contaminant Zone that have contacted PCB Remediation
           Wastes shall not be permitted to move outside of the area until they have been
           properly decontaminated. All soil within the excavations shall be assumed to be
           PCB Remediation Wastes <50 ppm unless the Contractor is otherwise instructed
           by the PCB Engineer. All waste handling and storage procedures, equipment
           decontamination procedures, and other Contaminant Zone Operations shall
           conform to the requirements of 40 CFR Part 761 Subpart D.

      B.   Dust Control

           The Contractor shall utilize an adjacent fire hydrant and appropriate hose for dust
           control. Water shall be applied to keep fugitive dust under control as needed and
           as directed by the PCB Engineer. Water will be provided by the DPW from an
           approved fire hydrant or other suitable source at no extra charge to the
           Contractor.

      C.   Excavation

           Excavation shall be shallow and performed in lift intervals no greater than one
           foot unless otherwise approved by the PCB Engineer. Excavation areas shall be
           clearly marked with stakes and labels.

           Excavation equipment shall be smooth edge blade without ripping teeth.
           Excavation shall be carried out in such a manner so as to minimize the mixing of
           soils to underlying soils. No ripping, plowing, harrowing or mixing of soils shall
           be permitted. Only excavation equipment that provides precise depth control will
           be permitted. No crane mounted clamshell or dragline excavators will be
           allowed.

           Excavation shall be carried out so as to remove contaminated soils from the edge
           farthest away from the edge where hauling vehicles will approach the
           Contaminant Zone. Contaminated soils shall not be moved over areas excavated
           and tested as below action levels and ready for backfilling, unless hauling
           vehicles move across the clean area to the edge of the Contaminant Zone.
           Excavation equipment shall not overfill their buckets so as to allow spillage of


                                                         PROJECT NO. BI-RT-844(ASB)
                                                        SECTION 028220
                             EXCAVATION OF PCB REMEDIATION WASTE SOILS
                                                            PAGE 7 OF 9

           soil across other contaminated or clean areas. The loose or excess soil shall be
           removed from the bucket within the active excavation area prior to moving the
           soil to the hauling vehicles. The Contractor shall be solely responsible for the
           cost of excavating, handling, storage, testing and disposal of soils that were
           previously clean and have tested as contaminated due to deficient Contractor
           operation practices and methods.

      D.   Personal Protective Equipment

           The Contractor shall assume that all personnel working within a contaminant
           zone shall be required to be equipped with Personal Protective Equipment (PPE).
           The Contractor’s health and safety officer will be responsible for determining the
           appropriate level of personal protection. That determination must be evaluated by
           a certified industrial hygienist and shall be based on actual laboratory data and
           monitoring from site operations. All personnel shall be required to go through an
           approved decontamination procedure. All personal protective garments shall be
           containerized and not reused after removal. The personal protective garments
           shall be disposed of as contaminated waste in an approved manner.

      E.   Remedial Action Levels

           The remedial action level for PCB contaminated soil shall be <1.0 PPM as
           specified in the Regulations of Connecticut State Agencies Sections 22a-133k-1
           through 22a-l 33k-3, inclusive, and the High Occupancy Standard without
           further restrictions in §761.61 (a)(4) of 40 CFR Part 761.
3.4   EXCAVATION COMPLETION
           Each excavation shall be considered complete after sufficient verification
           samples have been collected and analyzed and determined to meet remedial
           action levels. Verification samples shall be collected and analytical data
           reviewed by the PCB Engineer.

           Following the completion of an excavation, the Contractor shall decontaminate
           their equipment as required and remove from the area. The Contractor may
           remove temporary security fencing if the excavation is deemed by the PCB
           Engineer not to be a site hazard.
