1.0 Executive Summary

Environmental Health Services Inc. (EHSI) was contracted to conduct a

Hazardous Materials Survey on Barracks 7 (Building #54) located at the United States Coast Guard (USCG) station in Kodiak, Alaska. The survey efforts focused on identifying the existence, location, and quantities of asbestos containing building materials and Polychlorinated Biphenyls (PCBs) in light fixtures. The information obtained will be used to guide future renovations, general operations, and the maintenance of this facility.

Based on current findings for the Barracks 7 facility, asbestos is present at concentrations greater than 1% in vinyl floor tile and mastics, cove base mastics, thermal system insulation (TSI) with cross contamination on suspended ceiling, contaminated crawl space soils, and on a small portion of the roof system. Gypsum wallboard (GWB) and associated joint compound were assumed asbestos containing based on previous survey results, which are included in Appendix E.

Precautions must be taken to prevent worker exposure, emissions to the environment, and to comply with applicable regulations. Friable and non-friable asbestos containing material that may be disturbed or become friable during renovation activities should be removed. Non-friable asbestos containing materials that are in good condition and will not be disturbed during renovation activities may be left in place. PCB containing light ballasts and mercury containing light tubes should be disposed of in accordance with applicable regulations. A regulatory matrix is provided in Appendix D for reference.

This report describes the types of asbestos containing materials identified and the quantities and locations of these materials. The report also provides the condition of asbestos containing materials and their potential for disturbance. In addition, PCB containing light ballasts locations and quantities are also reported. The report first describes the building systems as a whole (roof, GWB, ceiling, floor tile/mastic, TSI, soils), followed by a descriptive summary of each building level (roof, attic, second floor, first floor, crawl space/boiler room). Sample figures and tables are included in applicable sections for reference. Sample numbers referenced in text descriptions are abbreviated to conform to sample figures.

2.0 Asbestos Overview

Asbestos is a naturally occurring mineral. Asbestos is divided into two mineral groups- Serpentine and Amphibole. The division between the two types of asbestos is based upon the crystalline structure. Serpentines have sheet or layered structure where Amphiboles have a chain-like structure. As the only member of the serpentine group, Chrysotile is the most common type of asbestos found in buildings. Also known as “white asbestos”, Chrysotile makes up approximately 90%-95% of all asbestos contained in buildings in the United States.

Asbestos is often referred to as “friable” or “non-friable” for classification purposes. Friable asbestos is defined as “crumbled or reduced to powder by hand pressure”. Asbestos which is friable or has become friable has a greater likelihood of releasing asbestos fibers into the air.

The Asbestos Hazard Emergency Response Act (AHERA) was promulgated in 1986. AHERA mandated that the Environmental Protection Agency (EPA) develop regulations for addressing asbestos in schools. The mandatory AHERA inspector requirement was implemented for any person who performs inspections for Asbestos Containing Material (ACM) on public and commercial buildings, however failed to include residential apartments or detached single family homes. The Asbestos School Hazard Abatement Reauthorization Act (ASHARA), enacted in 1990 and implemented in 1994, governs the training that asbestos workers, inspectors, supervisors, plan management writers, and abatement designers must receive to become accredited by the state. AHERA instituted the training requirement for any person who inspects for ACM following a recommendation by ASHARA.

Asbestos in buildings does not mean an endangerment to workers or occupants unless the condition of the asbestos is damaged or will become damaged due to human or environmental influences. The Occupational Safety and Health Administration (OSHA) regulate workers exposure to ACM during asbestos removal and stipulate use of trained asbestos workers and engineering controls for mitigating exposure. Worker protection is required by labor standards in 29 CFR and Alaska Administrative Code Title 8 (Chapter 61). Waste management is regulated under 40 CFR. Transportation of asbestos is regulated under 49 CFR. A regulatory matrix is provided in Appendix D.

3.0 Polychlorinated Biphenyls (PCBs) Overview

PCBs are mixtures of synthetic organic chemicals with the same basic chemical structure and similar physical properties ranging from oily liquids to waxy solids. PCBs were used in hundreds of industrial and commercial applications including electrical, heat transfer, and hydraulic equipment; as plasticizers in paints, and rubber products; in pigments, dyes, carbonless copy paper and many other applications. More than 1.5 billion pounds of PCBs were manufactured in the United States prior to cessation of production in 1977.

Concern over the toxicity and persistence in the environment of Polychlorinated Biphenyls (PCBs) led Congress in 1976 to enact section 6 (e) of the Toxic Substance Control Act (TSCA) that included among other things, prohibitions on the manufacture, processing, and distribution in commerce of PCBs. A regulatory matrix regarding PCBs and fluorescent light ballasts is provided in Appendix D.

4.0 Methods and Limitations

This Asbestos Survey was conducted pursuant to the requirements of the

Asbestos Hazard Emergency Response Act (AHERA), as specified in 40 CFR 763. The visual inspections, evaluations and sample collection were conducted by Randall Neel, AHERA building inspector certification number 3508-02-C19-02. Bulk asbestos sample analysis was performed by EMSL Laboratories, a certified National Voluntary Laboratory Accreditation Program (NVLAP) laboratory.

Prior to sampling, a pre-sampling site visit was conducted on December 13, 2002.

The visit offered the opportunity to review building composition for developing a sampling strategy. The building survey team completed all associated project fieldwork from January 28 – February 4, 2003.

No access was granted to the CPO Lounge and the Union Office. These areas were not included in this survey. Destructive investigation techniques to visual inspect and sample materials within wall cavities were not utilized as part of this survey.

A PCB survey of florescent lamp ballasts was conducted to identify any ballasts that did not specify “NO PCBs”. All individual florescent light fixture covers were removed and replaced to complete visual inspection of ballasts. No sampling of ballasts was performed.

5.0 Building System Results

5.1 Roof

The roof system was sampled at nine locations. Review of laboratory results indicated two samples collected at the air vent/access hatch were positive for asbestos.

Sample #80A was collected from the access hatch top and sample #75A was collected from the side. Because all other roof samples did not contain asbestos, it appears that the small hatch was not included in previous re-roofing activities.

5.2 Gypsum Wallboard (GWB) and Exterior Walls

The survey for project # 33-J8177, 33-J88180, 33-J00008, conducted by Jensen

Yorba Lott Inc. and included in Appendix E, identified two locations where GWB contained asbestos greater than 1%. For this survey, all GWB was assumed to contain asbestos and should be treated as such for future remodeling or maintenance.

The exterior wall system is constructed of wood shingles, felt paper, and plywood sheeting. Three bulk felt paper samples located between the shingling and plywood sheeting were collected and analyzed for the presence of asbestos. Laboratory results for all three samples associated with the felt paper were non-detect for asbestos.

5.3 Ceiling System

The first and second floors have suspended ceilings with GWB extending above the ceiling framework. All different suspended ceiling tile patterns observed were sampled during this survey. No ceiling tiles tested positive for asbestos, however three rooms on the first floor contain asbestos cross-contamination from damaged pipe insulation. First floor rooms with contaminated ceiling tiles include Room 111, the Janitor’s Room and the Janitor’s Laundry Room. Ceiling tile dust samples were collected and analyzed by Transmission Electron Microscopy (TEM). The samples were all positive for asbestos. The suspended ceiling tiles in these rooms are contaminated with asbestos dust.

The second floor Laundry Room contains non-friable cement asbestos board

(CAB) above the suspended ceiling. The CAB covers half of the ceiling area and was observed in good condition. The boiler room ceiling contains damaged non-friable CAB.

The CAB in the Laundry and Boiler Rooms have a low potential for disturbance.

5.4 Floor Tile and Mastic

First and second floor core samples were consistent throughout the building. The flooring system consists of multiple layers including: carpet, vinyl sheeting or vinyl tile on plywood, green vinyl, black felt and mastic, plywood and three inch tongue and groove planking. The green vinyl sheeting with black felt and mastic tested negative for asbestos. The vinyl tiled areas on plywood were the only asbestos containing flooring encountered in this survey.

Five different 12x12 vinyl floor tile patterns were observed. The most common vinyl tile pattern and associated mastic tested greater than 1% asbestos. Mastic on two other vinyl tile patterns also tested greater than 1% asbestos. All flooring areas with vinyl tile and mastic should be treated as asbestos containing.

5.5 Thermal Insulation

TSI piping was treated as homogenous materials throughout the building.

Following AHERA sampling methodologies, nineteen TSI piping samples were collected during the survey. The insulation used on elbows and joints throughout the piping system appears identical. Review of laboratory results and drawings indicates TSI piping systems contain different insulation.

TSI piping quantities were estimated as homogenous materials based on the steam piping system and old risers for the water system. The water system appears to have been upgraded with non-asbestos containing materials. This rationale was applied following review of laboratory results, review of drawings for Civilian Barracks Bldg.54 Rehabilitation dated 6-9-76, and visual inspection of newer copper piping on most of the water system. The mechanical drawings specified that five existing hot water risers were retained for new plumbing connections. The old risers and abandoned water system behind walls and chases that were not located should all be considered asbestos containing.

Asbestos containing pipe insulation exists on steam pipes in the boiler room, crawlspace and first floors. The straight runs of steam pipes contain hard white asbestos insulation with asbestos containing hard elbows and joints. The water pipes have fiberglass straight runs and non-asbestos containing hard elbows and joints.

The insulation used for water system elbows and joints is identical in appearance to the asbestos insulation used on the steam system. Because of these similarities in appearance, caution should be exercised when designing future remodeling. The asbestos containing steam pipe insulation is in fair condition with a few locations observed in poor condition. These areas are discussed in the floor by floor descriptions.

5.6 Asbestos Contaminated Soil

Suspected asbestos containing debris was observed in the crawlspace soils. Three of the debris materials contained greater than 1% asbestos. Most of the visual debris was on the south side of the crawl space and included CAB, paper insulation, and white insulation. Some of the white pipe insulation came back non-asbestos containing and is believed to be from the water pipe system. Because it is not feasible to differentiate the non-asbestos containing debris from asbestos containing debris, and the soils contain damaged friable insulation, all soils in the crawl space should be considered asbestos contaminated for purposes of remodel, operation, and maintenance.

6.0 Roof Level Summary and Results

The roof system was visibly inspected and in good condition. Eleven roofing material samples were collected in a random sampling procedure. Two roofing samples were reported to contain greater than 1% asbestos. The positive asbestos roofing materials are located on the west side dormer access hatch. Samples were collected at the access hatch following a visual confirmation that different types of roofing exist. Sample #80A was collected from the top portion of the built up access hatch and sample #75A was collected from the asphalt shingles on the dormer front. Because only these two samples tested positive for asbestos, it is likely this small area was omitted during previous re-roofing activities. The access hatch area measures approximately 45 square feet. The materials were observed in good condition and non-friable with low disturbance potential.

7.0 Attic Summary and Results

The attic is divided into three distinct sections. Each section measures approximately 60 feet long by 45 feet wide separated by a non-mudded GWB wall with a door access. Nineteen bulk samples of various materials were collected throughout the attic. Materials sampled included: thermal system insulations, building insulation and backing, chimney block mortar, cloth wire wrap and asphalt roofing debris. Sample #6A, a black tar sealant collected from the ducting vent, contained greater than 1% asbestos.

The ducting sealant material measures approximately five feet long by two inches wide and is located directly behind the attic access hatch. This material is non-friable and in good condition with a low potential for disturbance.

8.0 Second Floor Summary and Results

Twenty-seven bulk samples of various materials were collected on the second floor. Materials sampled included: multiple layer flooring, floor tiles and mastics, vinyl sheeting, cove base and mastics, suspended ceiling tiles, CAB, TSI on pipe and a light gasket.

PCB containing light ballasts in three light fixtures are located on the second floor secured bathroom. All other florescent fixtures have “No-PCBs” printed on the ballasts.

Florescent light tubes are assumed to contain mercury vapor. Figure 3 provides locations of PCB containing light ballasts.

Multiple layer flooring include: carpet, vinyl sheeting or vinyl tile on plywood, a green vinyl layer, a black felt and mastic layer, plywood and three inch tongue and groove planking. Four vinyl tile and associated mastic samples contain greater than 1% asbestos. All areas containing vinyl tile and mastic are in good condition with a low potential for disturbance. Because it is not visually feasible to distinguish between asbestos/non-asbestos containing mastics associated with vinyl tiles, all vinyl tile areas should be considered asbestos containing. No vinyl sheeting tested positive for asbestos.

Vinyl Floor Tile:

Location: Est. Quantity Kitchen / Room 203/ Storage Rooms 497 sq/ft

Cove base and mastic was included as homogenous materials throughout the building. Although the cove base mastic on the second floor tested negative for asbestos, two cove base mastic samples on the first floor were reported greater than 1% asbestos.

Visual inspection confirmed the presence of multiple layers of cove base mastic on the second floor. Because of the multiple layer of mastics observed and first floor mastic testing positive for asbestos, all cove base mastic should be considered asbestos containing.

Cove Base/Mastic

Second Floor 2,569 lineal ft

Three ceiling tile samples were collected throughout the second floor. Ceiling tiles from the first and second floors were included as one homogenous area. All ceiling tiles collected from the second floor tested negative for asbestos.

The second floor Laundry Room contains non-friable cement asbestos board (CAB) above the suspended ceiling. The CAB contains greater than 1% asbestos and covers half of the ceiling area. The CAB in the Laundry Room is in good condition with a low potential for disturbance.

CAB

Laundry Room 100 sq/ft

A TSI piping sample (#23A) was collected from the second floor men’s bathroom steam pipes. The hard elbow was non-detect for asbestos. However, first floor steam pipe system TSI samples were greater than 1% asbestos. The TSI pipe system was treated as homogenous materials located throughout the building, therefore all TSI hard elbows associated with the steam pipe system should be considered asbestos containing.

Because destructive methods on GWB were not performed, and available drawings do not indicate pipe locations, TSI piping quantities were estimated as a homogenous material based on steam piping system and old risers from the water system. A descriptive explanation is provided under Building System Results, Thermal System Insulation. TSI quantities representing the second floor are identified in Section 9 (first floor). This piping terminates at the second floor and was included in first floor estimates.

GWB and joint compound are assumed to contain asbestos.

9.0 First Floor Summary and Results

Thirty-one bulk samples and three TEM samples were collected on the first floor.

Materials sampled included: multiple layer flooring, floor tiles and mastics, vinyl sheeting and mastics, cove base and mastics, suspended ceiling tile, TSI on pipe, wall board in bathrooms and sink resins.

Multiple layer flooring include: carpet, vinyl sheeting or vinyl tile on plywood, a green vinyl layer, a black felt and mastic layer, plywood and three inch tongue and groove planking. Eleven vinyl floor tile and mastic samples contain greater than 1% asbestos. All areas containing vinyl tile and mastic are in good condition with a low potential for disturbance. Because it is not feasible to distinguish between asbestos/non-asbestos containing mastics associated with vinyl tiles, all vinyl tile areas should be considered asbestos containing. No vinyl sheeting tested positive for asbestos.

Vinyl Floor Tile:

Men’s/Women’s Bathroom/Janitor Room/Laundry 252 sq/ft

Two samples of cove base mastic are greater than 1% asbestos. All cove base mastic should be considered asbestos containing.

Cove Base/Mastic Location: Est. Quantity Second Floor 1,673 lineal ft

TSI sampled on the steam system pipes contain greater than 1% asbestos and should all be considered asbestos containing. The condition of insulation on observable steam pipes was fair; however three locations are in poor condition. Room 111, the Janitor’s Room and Janitor’s Laundry Room contain TSI joints in poor condition with confirmed cross-contamination on suspended ceiling tiles. TEM vacuum samples were collected and analyzed for confirming the presence of asbestos dust. The suspended ceilings within these three areas should be treated as asbestos containing. Damaged TSI joints are highly friable material with potential for disturbance from handling or air erosion.

10.0 Boiler Room and crawl space

Four boiler room and 11 crawl space samples were collected. Materials sampled included: CAB, TSI pipe, chimney debris, vibration gaskets, TSI in soils.

Non-friable CAB is present on the boiler room ceiling. The ceiling CAB is damaged with a low potential of disturbance.

CAB

Location: Est. Quantity Boiler Room 500 sq/ft

The steam pipes in the boiler room and crawl space contain friable asbestos in fair condition with a low potential for disturbance. The crawl space steam pipe located throughout the perimeter is generally in fair condition. The steam pipes are friable with a low potential for disturbance. A steam pipe located at the southeast corner was observed in poor condition.

TSI Steam Piping

Boiler Room 90 lineal ft.

Crawl Space 420 lineal ft.

Asbestos contamination is evident throughout the crawl space soils. Most of the visual debris was on the south side of the crawl space and included CAB, paper insulation, and white insulation. It should be noted that the observed CAB in the crawl space was minimal and likely originated from small damaged pieces observed missing from the boiler room. Because it is not feasible to visually differentiate the non-asbestos containing debris from asbestos containing debris (namely TSI debris), and the soils contain damaged friable asbestos insulation, all soils in the crawl space should be considered asbestos contaminated.

11.0 Recommendations

Based on interpretations of asbestos sample results and site investigation, there are several areas of concern. Eight types of material tested positive for asbestos including: roofing material, GWB, vinyl floor tile with mastics, cove base mastic, CAB, TSI, cross contamination of suspended ceiling tiles and crawl space soils.

Three florescent light fixtures containing assumed PCB light ballasts were located in the second floor secured bathroom. Florescent light tubes throughout the building are assumed to contain mercury vapor. All of these items have special handling and disposal requirements.

Asbestos containing roofing material is considered a Category I non-friable material by EPA 40 CFR Part 61 Subpart M. The removal of asbestos containing roofing material is a Class II abatement task per OSHA 29 CFR 1926.1101. The roofing material and asphalt shingles associated with the small dormer roof access both contain asbestos.

During survey inspection, the roof was observed in good condition and does not pose an asbestos health hazard. Abatement workers with current state of Alaska asbestos abatement certification should be used for any roofing removal or disturbance of this section of roofing.

Gypsum wall board was tested in a previous survey. This survey prepared by

Jensen Yorba Lott Inc. for USCG Maintenance and Logistics Command, Pacific Engineering Unit, Project #33-J8177, 33-J8180, 33-J00008 reported two GWB samples contain asbestos greater than 1%. During this survey inspection, all GWB was assumed to be asbestos containing throughout the building. The GWB was observed in good condition and does not pose an asbestos health hazard. This material is considered Category II non-friable material by EPA 40 CFR Part 61 Subpart M. The removal of asbestos containing GWB is a Class II abatement task per OSHA 29 CFR 1926.1101.

Abatement workers with current state of Alaska asbestos abatement certification should be used for any GWB removal or disturbance in this facility. Special warning should be given to workers that damaged TSI may be discovered in hidden sections behind GWB.

Flooring samples indicate most flooring is non-asbestos containing. Carpeted and vinyl sheeting areas and the observed old layer of vinyl and mastic under the top layer of plywood were non-asbestos. Vinyl tiled areas tested positive for asbestos. The tile mastics used are also asbestos containing. During survey inspection, the vinyl flooring was observed in good condition and does not pose an asbestos health hazard. This material is considered Category I non-friable material by EPA 40 CFR Part 61 Subpart M. The removal of asbestos containing resilient flooring is a Class II abatement task per OSHA 29 CFR 1926.1101. Abatement workers with current state of Alaska asbestos abatement certification should be used for any vinyl tile removal or disturbance in this facility.

Cove base mastics were tested throughout the building. Two samples tested positive for asbestos. During survey inspection, it was observed that behind the cove base several layers of mastics exist. Cove base and mastics were observed in good condition and pose no immediate asbestos health hazards. Cove base removal would result in disturbing the mastics. This material is considered Category II non-friable material by EPA 40 CFR Part 61 Subpart M. The removal of asbestos containing construction mastics is a Class II abatement task per OSHA 29 CFR 1926.1101. Abatement workers with current state of Alaska asbestos abatement certification should be used for any cove base removal or disturbance.

CAB identified in second floor laundry room and the boiler room tested positive for asbestos. During survey inspection, the laundry room CAB was observed in good condition and does not pose an immediate asbestos health hazard. Boiler room CAB has broken areas and listed in poor condition. CAB is non-friable and the location of material gives it a low potential for disturbance thus does not pose an immediate asbestos health hazard. This material is considered Category II non-friable material by EPA 40 CFR Part 61 Subpart M. The removal of CAB is a Class II abatement task per OSHA 29 CFR

1926.1101. Abatement workers with current state of Alaska asbestos abatement certification should be used for any CAB removal or disturbance.

TSI is considered a Regulated Asbestos Containing Material (RACM) friable material by EPA 40 CFR Part 61 Subpart M. The removal of this TSI is a Class I abatement task per OSHA 29 CFR 1926.1101. Abatement workers with current state of Alaska asbestos abatement certification should be used for any asbestos containing TSI removal or disturbance.

Water system TSI observed and sampled is in fair condition. Based on review of the historical mechanical drawings combined with observations of newer copper piping made during this survey, upgrading of most water system piping has occurred. Review of hard elbow sample results associated with the upgraded water system indicates they are non-asbestos containing. Reviews of TSI sampling results also support this finding.

Sample 54B0131-51B collected on the old water system riser is asbestos containing.

Only water system TSI that is associated with the water system upgrades should be considered non-asbestos containing. All old risers and abandoned plumbing hidden behind GWB not located in this survey should be considered asbestos containing. TSI materials used during water system upgrade are identical in appearance to asbestos containing TSI. Trained asbestos workers are required to remove asbestos containing water system TSI or piping during remodel activities. Trained asbestos workers are required for removal of GWB. During the GWB abatement activity, it is recommended that trained asbestos workers abate all exposed insulated piping to prevent a potential exposure scenario from misidentifying asbestos containing TSI.

Steam system TSI tested positive for asbestos. This material is in fair condition with four areas observed in poor condition. Room 111, Janitors Laundry Room, and the Janitors Room have significantly damaged TSI above the suspended ceiling tiles. TEM samples confirmed the presence of asbestos dust. Because this material is very friable, all ceiling tiles in these rooms should be considered asbestos contaminated. These areas have high potential for asbestos health hazards and should be cleaned of contamination as soon as possible using trained asbestos workers.

Crawl space soils observed have TSI and CAB mixed with the soil. This could be the result of past abatement or repairs. Debris samples collected under the water system tested negative for asbestos. Samples collected in other locations tested positive for asbestos. Crawl space debris materials (especially TSI) are similar in appearance making it impossible to differentiate visually. This area poses high potential for an asbestos health hazard. As an interim measure, crawl space soils should be cleaned of gross contamination as soon as possible using trained asbestos workers. Future abatement planning should implement a more permanent solution such as soil removal, soil encapsulation or installation of visqueen barriers.

No sampling was conducted in the CPO/Union Office.
