1.0 Executive Summary

Environmental Health Services Inc. was contracted to conduct a Hazardous Materials Survey of the Lorsta Office (Building 576) located on Aviation Hill near the United States Coast Guard (USCG) station in Kodiak, Alaska. The survey efforts focused on identifying the existence and quantity of asbestos containing gypsum wall board (GWB) and joint compound in Room 205 and exterior asbestos and Lead-Based Paint (LBP) containing materials. The information obtained will be used to guide the future renovations, general operations, and maintenance of this facility.

Based on current findings for the Lorsta Office (Building 576), asbestos is present at concentrations greater than 1% in the roofing system and at one exterior location where black sealant was used to seal building crevasses. Seven exterior building locations were confirmed to contain LBP greater than 1 mg/cm2.

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) to 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 it 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, and 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) regulates workers exposure to ACM during asbestos removal and stipulate use of trained asbestos workers and engineering controls for mitigating exposure. A regulatory matrix applicable to the hazardous materials identified in this report is provided in Appendix D.

3.0 Lead-based Paint (LBP) Overview

Lead is a heavy, soft, easily worked, bluish metal that is mined out the earth.

Lead has been used for many different applications throughout the centuries. It has been used in pipes, lining for storage vessels, glazing in pottery, added to paint, roofing, electrical conduits and combined with other metals.

Lead was added to paint up until the 1950’s for three main reasons: pigment, added durability and corrosion control, and as a drying agent. The use of LBP declined due to the introduction of latex and titanium oxide paints. In 1971 Congress made the Lead-based Paint Poisoning Prevention Act (LBPPPA) which gave a limit to the amount of lead paint could contain. Later, Congress passed legislation to reduce lead-based paint hazards called the Residential Lead Hazard Reduction Act (Title X). The Housing and Urban Development (HUD) agency next created the Guidelines for the Evaluation and Control of Lead-based Paint Hazards in Housing based on the requirements set forth in Section 402 of Title X. The development of Title X was largely to support reduction of LBP hazards in housing, especially target housing where a potential for childhood lead poisoning exists. The Title X Guidelines use a Federal limit for lead in paint as 1.0 mg/cm² or more than 0.5% by weight.

Section 402 of the Toxic Substance Control Act (TSCA) details the requirements and certifications needed to conduct lead-based paint inspections, risk assessments, designers, supervisors, and abatement workers. The Occupational Safety and Health Administration (OSHA) also regulates workers exposure to lead during disturbance activities as defined in the 29 CFR 1926.62. A regulatory matrix applicable to the hazardous materials identified in this report is provided in Appendix D.

4.0 Methods and Limitations

The 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 was conducted by Randall Neel, AHERA building inspector certification number 3508-02-C19-02. Asbestos bulk sample analysis was performed by EMSL Laboratories, a certified National Voluntary Laboratory Accreditation Program (NVLAP) laboratory.

All lead-based paint testing was performed on site using a Niton XRF 300. The primary lead inspector was Alan Caldwell (EPA Lead Risk Assessor #AK-09-122005- 047).
