2.0 ASBESTOS

2.1 ASBESTOS SURVEY PROCEDURES

The survey was performed by visually observing accessible areas within the scope of work.

EPA/AHERA accredited inspectors performed the visual observations (refer to Appendix B for personnel qualifications).

After the overall visual survey was completed, representative sampling areas were determined.

The surveyors delineated homogeneous areas of suspect materials and samples of each material were obtained, in general accordance with regulations as established by the Occupational Safety and Health Administration (OSHA) and NESHAP. The field surveyors determined sample locations based on previous experience. Both friable and non-friable materials were sampled. A friable material is one that can be crushed when dry by normal hand pressure. This survey did not include the demolition of building components to access suspect material.

After completion of the fieldwork, the samples were delivered to Arrowhead Technologies, LLC, a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory for analysis. The samples were analyzed by Polarized Light Microscopy (PLM) coupled with dispersion staining, in general accordance with EPA-600/R-93/116. Utilizing this procedure, the various asbestos minerals (chrysotile, amosite, crocidolite, actinolite, tremolite, and anthophyllite) can be determined. The percentages of asbestos minerals in the samples were visually determined by the microscopist. Please note that the EPA designates all materials containing greater than one percent asbestos as an “asbestos-containing material” (ACM).

Regulated Asbestos-Containing Material (RACM) is defined as (a) Friable asbestos materials,

(b) Category I non-friable ACM that has become friable, (c) Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by this subpart.

Category I and Category II non-friable ACM, as defined by the EPA:

Category I non-friable ACM means asbestos-containing packings, gaskets, resilient floor covering, asphalt roofing products, and pliable sealants and mastics that are in good condition and not friable, containing more than one percent asbestos, as determined using the method specified in Appendix E, Subpart E, 40 CFR Part 763, Section 1, PLM.

Category II non-friable ACM means any material, excluding Category I non-friable ACM, containing more than 1 percent asbestos as determined using the methods specified in Appendix E, Subpart E, 40 CFR Part 763 Section 1, PLM that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

2.2 IDENTIFIED SUSPECT ASBESTOS-CONTAINING MATERIALS

A total of two hundred seven (207) samples of suspect building materials were collected from the facility during the survey, representing sixty-five (65) different identified homogeneous areas. The results of the laboratory analyses are included in Appendix A.

A summary of the homogenous sampling areas of suspect ACM determined to be present is outlined in the following table.

3.0 LEAD-CONTAINING PAINT

3.1 LEAD-CONTAINING PAINT SURVEY PROCEDURES

The lead-containing paint survey was performed by visually observing accessible painted component surfaces associated with the scope of work. The protocol used in this lead paint survey is a modified version of the survey methodology established by HUD. The protocol was modified to conform to the specific parameters of this project.

During the walk through of the facility, each area was observed and an inventory of painted surfaces was developed. The surveyor then subdivided the areas into homogeneous areas of apparent similar paint history.

Testing of the painted surfaces was performed by collecting representative paint chips. All samples were submitted to EMSL Analytical, Inc., an accredited laboratory recognized under EPA’s National Lead Laboratory Accreditation Program (NLLAP). These samples were analyzed by EPA Method 3050B/7000B and the results are reported in percentage of lead by weight of the paint sample (% Wt). Please note that any detectable concentration of lead in the paint is designated by OSHA as “lead-containing.”

3.2 IDENTIFIED SUSPECT LEAD-CONTAINING PAINT

The identified suspect lead-containing coatings are described in the following table:

1 BOLD result indicates lead-containing paint.

2 The requirements of the OSHA Lead in Construction Standard 29CFR 1926.62 are invoked if any amount of lead is present in the sample;

there is no minimum concentration.

4.0 CONCLUSIONS AND RECOMMENDATIONS

4.1 ASBESTOS – GENERAL

Asbestos-containing materials (ACMs) were identified in the scope of this survey. General and specific conclusions and recommendations are provided below.

The EPA, OSHA and the State of Florida have promulgated regulations dealing with asbestos.

For commercial building owners, the EPA NESHAP (40 CFR 61) regulations require removal of RACM, prior to conducting activities which might disturb the material. They also deal with notification, handling and disposal of asbestos.

The EPA recommends that an Operations and Maintenance (O&M) Program be developed for any facilities with ACM, and this Program should address all ACM (known and/or assumed) present. The O&M Program establishes notification and training requirements along with special procedures for working around the ACM. The O&M Program would remain in effect until all asbestos is removed.

Category I and Category II non-friable materials, as defined by the EPA, may remain within a facility during demolition with no potential cessation of work, provided they remain non-friable and the appropriate engineering controls (i.e., wet methods) are utilized, with the resulting waste disposed of as asbestos-containing waste. However, there is no guarantee that these materials will remain non-friable. If the materials become friable, then they are classified as RACM.

RACM, as defined by the EPA, must be removed prior to renovation or demolition activities that may disturb the materials.

The OSHA regulations deal with employee exposure to airborne asbestos fibers. The regulations restrict employee exposure, and require special monitoring, training and handling procedures when dealing with asbestos. Additionally, OSHA has regulations that may supersede the EPA regulations. In order to protect the worker, OSHA has established a permissible exposure limit (PEL), which limits employee exposure to airborne fiber concentrations. OSHA requires objective evidence that the PEL will not be exceeded, as justification that personal air monitoring and engineering controls will not be required. OSHA has also established rules requiring the containerization and labeling of asbestos waste.

The State regulations require that anyone involved in asbestos consulting activities be a licensed asbestos consultant and that anyone involved in asbestos abatement, with the exception of roofing materials, be a licensed asbestos abatement contractor.

4.1.1 ASBESTOS – SPECIFIC

MSV-01: Backing Associated with Olive Sheet Vinyl (Field Services Building) TSI-01: White Hard Block Pipe Insulation (Electric Operations Offices and Warehouse)

These materials are defined by the EPA as RACM. The backing associated with sheet vinyl in the field services building was observed to be in good condition, and did not appear to present a significant issue, as observed, at the time of the survey. The hard block pipe insulation in the electric operations offices and warehouse building was observed to be in significantly damaged condition, and presents a significant issue, as observed, at the time of the survey. We recommend that a licensed asbestos abatement contractor properly remove and dispose of the identified RACM prior to conducting demolition activities that might disturb the ACM.

M-04: Grey Exterior Caulk (Waste Water Admin Building) RF-02: Aluminum Coating on Mechanical Equipment Flashing (Waste Water Admin Building) M-01: Grey Interior Caulk (Waste Water Admin Warehouse) M-02: Grey Exterior Caulk (Waste Water Admin Warehouse)

These materials are defined by the EPA as a Category I non-friable materials. These materials may remain within a facility during demolition with no potential stoppage of work provided they remain non-friable. However, there is no guarantee that it will remain non-friable. If a material becomes friable, then it is classified as RACM. RACM, as defined by the EPA, must be removed prior to renovation or demolition activities that may disturb the materials. Also, OSHA has additional requirements that may supersede the EPA rules. These materials do not appear to present a significant issue, as observed, at the time of the survey. We recommend that the identified Category I material be maintained as part of an O&M Program and periodically monitored for any changes in condition prior to demolition. As discussed above, in order to protect the worker, OSHA has established a PEL which limits airborne fiber concentrations. Objective evidence that the PEL will not be exceeded is required by OSHA as justification that personal air monitoring and engineering controls will not be required. OSHA has also established rules requiring the containerization and labeling of asbestos waste.

Should prior abatement be desired, the work must be performed in accordance with Federal, State, and local regulations. In lieu of abatement, demolition utilizing the wet method is acceptable by a demolition contractor properly trained and certified to conduct Class II asbestos work, along with proper disposal and transport of the demolished materials to an approved landfill as asbestos-containing waste.

M-05: Black Sink Undercoat (Electric Operations Offices and Warehouse) MCP-01: Grey Cementitious Panels (Electric Operations Offices and Warehouse)

These materials are defined by the EPA as Category II non-friable materials. These materials have a high probability of becoming friable by the forces expected to act on the material in the course of demolition operations. Therefore, it will be classified as RACM.

The identified RACM does not appear to present a significant issue, as observed, at the time of the survey. We recommend that the identified RACM be maintained as part of an O&M Program and periodically monitored for any changes in condition prior to demolition. Additionally, we recommend that a licensed asbestos abatement contractor properly remove and dispose of the RACM prior to conducting demolition activities that might disturb the ACM.

4.2 LEAD-CONTAINING PAINT

Lead-containing paint (LCP) was identified in twenty-five (25) of the fifty (50) samples.

Under the present OSHA lead construction standard, all identified lead-containing paint affected by construction activities falls under the requirements of 29 CFR 1926. There are no current government guidelines defining a lead paint concentration that creates a hazardous atmosphere when disturbed. Based on current OSHA guidelines, for those employees who will be disturbing lead-containing paint, their employer must make an initial determination by monitoring employee exposure if any employee is exposed to lead at or above the established Permissible Exposure Limit (PEL) of 30 µg/m3 (8-hour TWA).

The employer must implement OSHA prescribed protective measures until they can demonstrate that the employee exposure is not in excess of the PEL. Due to the planned demolition or renovations for these facilities, GLE’s recommendations are as follows:

For all identified lead painted materials where abrasive blasting, welding, cutting and/or torch burning are planned, removal of lead paint is to be completed by a properly trained lead removal contractor.

For all identified lead painted materials where manual demolition (e.g. drywall), manual scraping, manual sanding and heat gun applications are planned: provide workers with interim protection as outlined in the OSHA Lead in Construction Standard until the employee exposure monitoring indicates that that all tasks being performed are not exposing employees above the

PEL.

The interim employee protection measures include but are not limited to the following:

appropriate respiratory protection; appropriate personal protective clothing and equipment;

change areas; hand washing facilities; biological monitoring; and training.

All waste generated during the lead paint removal and during subsequent manual demolition or renovation activities should be characterized by Toxicity Characteristic Leaching Procedure testing for lead for waste disposal purposes.

5.0 LIMITATIONS AND CONDITIONS

As a result of previous renovations, there may be hidden materials, such as floor tile, sheet vinyl flooring, insulation, etc. These materials may be found in various areas hidden under existing flooring materials or in wall cavities. Any materials or coatings found during construction activities, either not addressed in this survey report, or similar to the ACM or LCP identified in this survey report should be assumed to be ACM or LCP until sampling and analysis documents otherwise.

Because of the hidden nature of many building components (i.e. within mechanical chases), it may be impossible to determine if all of the suspect building materials have been located and subsequently tested. Destructive testing in some instances is not a viable option. We cannot, therefore, guarantee that all potential ACM or LCP has been located. For the same reasons, estimates of quantities and/or conditions are subject to readily apparent situations, and our findings reflect this condition. We do warrant, however, that the investigations and methodology reflect our best efforts based upon the prevailing standard of care in the environmental industry.

These samples were analyzed by layers. Specific layer or component asbestos content is indicated when relevant. The EPA considers a material to be asbestos containing only if it contains more than one percent asbestos by Calibrated Visual Area Estimation (CVAE). EPA regulations also indicate that Regulated Asbestos Containing Materials (RACM) -- materials which are friable or may become friable -- be further analyzed by point counting when the results indicate less than ten percent asbestos by CVAE. Arrowhead utilizes CVAE on a routine basis and does not include point counting unless specifically requested.
