Building Materials

PCBs In Building Materials

Where are they found?

• Buildings and Structures constructed/renovated from 1950 to 1978

• Masonry joints and painted surfaces of concrete sidewalks and pools

In what building products have we been encountering PCBs?

Common Sources

•Caulking, Grout, Sealants, Paints, Insulation,

•Ceiling Tiles, Roofing Materials, Adhesives, Gasket Materials,

•Transformer/Hydraulic Oils

Various building related components

•HVAC equipment, Mastic, Light Ballasts, Capacitors and other

•Electrical Equipment

Current products manufactured outside the US

•Caulking, Sealants and Adhesives

PCBs In Building Materials

Likely affected areas?

PCBs In Building Materials

•Underlying Soil

•Roofs

•HVAC equipment

•Ceilings

•Elevator shafts

•Window and door frames

•Masonry joints

•Expansion joints

•Painted surfaces

•Porous Surfaces

Where do PCBs Leach/Spread?

•Abutting surfaces

•Underlying/surrounding soils

•Porous surfaces and substrates (wood,

concrete, pavement)

•Dust

Migration Pathways

Are you restoring, renovating or demolishing a Building or

Structure built between 1950 to 1978? (Can be as simple as

replacing a window)

•Yes (Test) due to Disposal Facility Acceptance of Waste and

OSHA Worker Safety Notification.

•No, but being pressured to Investigate if PCBs are a Concern

(Perform Air Sampling by Qualified Company)

(Keep in mind that Waterproofing, Repointing, Grouting and

concrete removal can all be sources of PCB contamination)

Testing Guidance

What do you do once you find PCBs? •Proper Regulatory Notification (EPA, State)

•Create Comprehensive PCB Work Plan

•Select Qualified Remediation Contractor

•Experienced and Trained Personnel

•Proper Personnel Protection Equipment, Containment Procedures,

Waste Management, and Decontamination of Equipment

•Regulatory Reporting

Remediation/Abatement Process

Case Study-Confidential Town Elementary School

PCB Contaminated Caulking Removal and Encapsulation

TMC was contracted to remove and encapsulate PCB-containing caulk found at

the elementary school that was discovered during a hazardous materials review

conducted in April of 2012.

The contract was awarded to TMC in mid-August after a competitive bid process.

With the new school year set to begin at the end of August, the abatement

timeframe was extremely tight, with approximately one week to complete the

abatement and encapsulation. TMC was able to successfully expedite the

required EPA submittal and review process due to the diligent efforts of our

experienced personnel and EPA’s precious time devoted to this project.

TMC provided a value-engineered solution, improving the original plans which

included an epoxy paint encapsulant. An alternate rigid metal over the remaining

PCB containing material was installed to encapsulate the areas after caulking

removal.

In order to prevent an unacceptable delay in the start of the school year, TMC

worked closely with the Town’s engineer/consultant and the EPA to accomplish the

project on-time through an innovative alternative solution.

Confidential Town- Elementary School PCB Contaminated Caulking Removal

• Time sensitive schedule

• Dry time of multiple coats and climate

• Surfaces that would not allow epoxy paint to adhere

Project Obstacles:

• Alternate solution prevents exposure and contact to adjacent

wall surfaces

• Rigid system would protect young children against contact

into the exposed cracked joints

• Reduce maintenance from graffiti scratches

• Can be removed for demo

Alternate Encapsulation Solution:

Rigid metal panels vs. epoxy coating

Summary

• A well developed PCB Work Plan is one of the most

important steps for EPA acceptance and execution of the

abatement/remediation.

• Highly Trained and Experienced Remediation Contractor

is Key to Success.

• A Teaming Relationship with the Engineer, Consultant,

Client and Remediation Contractor is extremely beneficial

for Successful Project Execution.
