Miller-Driscoll Project Rationale:
•
School Requires Renovations to Meet Current Standards
•
Safety/Security
•
Ventilation
•
Acoustics
•
Technology
•
Energy Efficiency
•
Significant Deferred Capital Infrastructure Projects Required
•
Pre-School Space Inadequate to Accommodate Growing Special Needs Pre-K
Population
•
Provide Value to the Community
• Create dedicated Pre-K space
on lower level with separate
entrance and drop off/pick
up loop
• Replace old ‘peach core’ with
new classrooms and
cafeteria
• Convert south cafeteria to
additional gym space
• Reconfigure administrative
are to create single, secure
K-2 entrance
• Relocate playgrounds to rear
of building
• Demolish north cafeteria
wing and replace it with
additional parking

Hazardous Building Materials Investigation
Summary
• Investigation scope was designed based on the scope of the
contemplated renovation.
• Miller-Driscoll School – majority of the school is 1960’s
construction; certain areas were constructed in 1989 and 1995.
• Asbestos, lead, PCBs & other regulated items were expected to
be identified, as they are typical for a school of this age.
Presence of these building materials does not indicate a
health/safety risk.

Asbestos
• Miller wing/Driscoll wing – floor tile/mastic, glues,
chalkboards, fire door insulation, duct insulation (kitchen),
pipe insulation, fireproofing (boiler room areas), roof
flashing & caulking/glazings.
• Majority of ACM is non-friable materials.
• Some friable materials are present, however they are
located in inaccessible areas above ceiling or in fixed wall
cavities.
10
Miller-Driscoll School Renovation
Lead
• Majority of the paints associated with plaster walls, sheetrock
walls, concrete walls, window components & door components
contained non-detectable/low levels of lead for both the Miller
and Driscoll wings.
• Higher lead levels (>1.0 mg/cm2) were found in the paint
coatings of the structural steel (I-beams) in non-accessible
areas behind walls & ceilings of both the Miller and Driscoll
wings. These areas are subject to EPA Renovation Repair and
Painting (RRP) in “child occupied areas” with kids <6.
• Paints were found to be intact.
11

PCBs
•
•
•
•
•
•
•
Unregulated PCBs (<1ppm).
Low level State Regulated (≥1ppm but <50 ppm).
Federally Regulated (≥50 ppm). Federally-regulated PCB-containing materials have
different disposal requirements.
~80% of caulkings/glazings were found to either be unregulated or state regulated.
~20% of caulkings/glazings were federally regulated. *(Atypically low for a school
this age).*
Caulkings/glazings generally intact.
2 caulkings (50-150 ppm Driscoll classroom windows), 3 caulkings/glazings (2,0003,000 ppm Old garage cooler ceiling, Driscoll hallway windows, Driscoll cafeteria
doors) & 1 caulking (>150,000 ppm Miller wing pod windows exteriors).
12

Other Regulated Items
• Hg bulbs, halogen bulbs, ballasts, CFCs, printed
circuit boards (typical components).
• TRC’s technical specification requires use of a CT
DEEP licensed spill contractor for proper handling
and packing for recycle/disposal.
13
Miller-Driscoll School Renovation
Abatement Specifications/SIP
• Technical specifications for the abatement of hazardous building
materials (contractor certification, setup process, removal activities,
engineering controls, work practices, disposal, work area clearances,
etc.) approved by local building officials & the CT Bureau of School
Facilities (BSF).
• Written by CTDPH licensed/certified professionals.
• Self-Implementing Cleanup Plan (SIP)
– Plan that addresses the investigation and remediation of PCBs
identified at the site.
– Thoroughly reviewed by EPA and revised as requested.
– SIP approved by EPA on September 10, 2015.
14

Abatement Process
• As much work as possible will be conducted while the
students/staff are not in the building (e.g., summers,
school vacations, weekends). Any asbestos work that will
have to be done while “school is in session” will have a
specific safety plan in place, with pre-approval by CTDPH.
Parents/Teachers/Faculty will be notified. Any areas
where abatement is being conducted will not be
accessible to Students/Teachers/Faculty.
15
Miller-Driscoll School Renovation
Abatement Process (continued)
• Abatement of hazardous building materials done by
CTDPH-licensed and EPA/OSHA-trained contractors.
• Abatement contractor duties will included but won’t be
limited to:
– Setting up polyethylene negative pressure enclosures
(NPE).
– Using engineering controls during abatement (wet
methods & HEPA vacuuming) to prevent fibers/dust
from escaping the NPE.
– Proper disposal of waste.
16
Miller-Driscoll School Renovation
Abatement Process (continued)
•
TRC will be providing a full time CT licensed project monitor on-sight during
all hazardous building materials abatement. His/her duties will include but
won’t be limited to:
– Background air/dust monitoring before, during and after abatement
activities.
– Pre-visual inspections of NPE prior to the start of abatement.
– Ensuring abatement contractor is using all necessary engineering
controls.
– Post visual inspections to ensure all hazardous building materials have
been removed in the NPE.
– Conduct clearance testing prior to the breakdown of the NPE.
• PCM/TEM air testing (asbestos).
• PCB dust wipes/PCB substrate verification samples (PCBs).
