1. EXECUTIVE SUMMARY

PSI has conducted an Indoor Air Quality (IAQ) Assessment of the Air Traffic Control Tower at the Lackland AFB in San Antonio, Texas.

This survey was conducted at the request of Mr. Stephen Reus, Parsons Government Services., Inc., to establish a baseline regarding IAQ potentially resulting from previous moisture intrusion.

The scope of the IAQ Assessment was intended to address identifiable conditions within the areas of the facility as it relates to the recognition, evaluation, and control of mold within building. This assessment was intended to provide data regarding potential fungal amplification within the facility, general condition of heating ventilation and air conditioning (HVAC) systems, and building moisture conditions. The HVAC system was operating at the time of the assessment.

The assessment results indicate that the comfort parameters measured within the subject building were within the guidelines specified by ASHRAE for temperature and relative humidity were found to be within the referenced guidelines. Excessive moisture was not measured within the tested building material substrates. Based on the laboratory results for the air samples collected, no elevated concentrations of fungal spores were identified in comparison to the outside sample.

Based on the methodologies described in this report, this assessment has provided sufficient information to determine that fungal spore amplification is not present in the facility.

2. INTRODUCTION

An IAQ Assessment of the Air Traffic Control Tower located at Lackland Air Force Base in San Antonio, Texas has been conducted by Professional Service Industries, Inc. (PSI) to investigate reports of perceived IAQ problems potentially associated with occupant concerns. This assessment was conducted on August 13, 2014, by Mr. Joe Leal, Environmental Specialist, under the supervision of Guy Roberts, Mold Assessment Consultant. This survey was performed as a baseline assessment as part of a hazardous material assessment of the structure.

The survey was generally conducted in three phases as follows:

Phase 1 - Initial Evaluation - A preliminary evaluation was conducted by PSI which included interviews of the management and maintenance personnel providing information relative to potential exposure pathways. This data was used to focus the scope of work to be followed over the course of the sampling event.

Phase 2 – Physical Data Collection - A sampling plan was developed under the direction of a Texas Department of State Health Services (TDSHS) licensed Mold Assessment Consultant. Measurements were made of temperature and relative humidity in the selected areas of the facility through the use of an electronic Extech™ humidity/temperature device.

Physical data collection also included obtaining samples for total fungal spores in selected areas and comparative samples from the local outdoor environment.

Phase 3 - Project Report - This report outlines the survey findings based on the testing results and field observations. The report also discusses other observations concerning the area as they impacted the sampling events. This report includes discussion of sampling methodology, locations, analytical methods, results, and conclusions.

2.1 AUTHORIZATION

Authorization to perform the assessment was given by a signed copy of Purchase Order: PO- 0000183. Access to the site was provided by Mr. Stephen Reus, Parsons Government Services, Inc. representative.

2.2 SITE DESCRIPTION

The subject site upon which this assessment was conducted is located at the Air Traffic Control Tower at the Lackland Air Force Base, in San Antonio, Texas.

2.3 PROJECT BACKGROUND

This survey was conducted at the request of Mr. Stephen Reus, Parsons Government Services, Inc. representative as part of the hazardous material assessment/survey for the Air Traffic Control Tower at the Lackland Air Force Base in San Antonio, Texas,

2.4 PURPOSE AND SCOPE

The purpose of this IAQ Assessment was to evaluate conditions within the building as it relates to the recognition, evaluation, and control of mold within the structure. This assessment provides data regarding potential fungal amplification, general condition of HVAC systems, and building relative humidity conditions.

The assessment was completed in general accordance with the authorized scope of work.

3. ASSESSMENT ACTIVITIES

This assessment was conducted on August 13, 2014, by Mr. Joe Leal, Environmental Specialist, under the supervision of Guy Roberts, Mold Assessment Consultant. Prior to the commencement of assessment activities, the client provided site access to the building.

3.1 WALK-THROUGH EVALUATION

The walk-through evaluation was conducted throughout the building to observe suspect areas with reported fungal amplification issues. PSI was escorted by Mr. Stephen Reus, Parsons Government Services, Inc. representative during the walk through evaluation.

3.2 PHYSICAL MEASUREMENTS/GENERAL COMFORT PARAMETERS

3.3 PHYSICAL MEASUREMENTS

Measurement and recording of the air temperature is used to determine comfort level parameters associated with the indoor environment. The monitoring device was placed in each area and allowed to collect spot measurements while obtaining moisture meter readings and air samples.

The American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) provides guidance on comfort ranges for temperature depending on season. These numbers generally range from 68 to 76o F during the winter months and from 72 to 80o F during the summer months. The ranges are dependent on available humidity with the lower end of the temperature range coinciding with the higher humidities. The temperatures measured within the area were within this range.

Measurement and recording of the relative humidity is used to indicate comfort level parameters associated with the indoor air. Overly dry as well as overly humid air are both indicators of air quality provided by the HVAC system. The monitoring device was placed in the sampling areas for spot check measurements while collecting air sample and moisture meter readings. ASHRAE recommends maintaining the humidity between 30 and 70%, ideally between 40 and 60%. The relative humidity levels within the area were within this range.

Utilizing a Ryobi Moisture Meter, PSI performed moisture testing on the substrates within the areas. PSI did not observe elevated moisture content measurements on accessible walls.

3.4 TOTAL AIRBORNE FUNGAL (MOLD) STRUCTURES (VIABLE AND NON-VIABLE)

Total Fungal Structures were collected using utilizing Air O Cell TM spore traps that deposits the spores onto a slide where they are identified and enumerated microscopically. The Air O Cell TM

3.3.1 TEMPERATURE

3.3.2 RELATIVE HUMIDITY

3.3.3 MOISTURE METER RESULTS

spore trap was connected to a sampling pump calibrated to flow at 15 liters per minute for a sampling period of ten (10) minutes, resulting in a total sample volume of 150 liters. An outdoor sample was also collected for comparison purposes.

The advantage to using this method is quick turn-around time from the laboratory, as the samples are evaluated microscopically and do not require incubation. Please note that spores including viable and non-viable spores are counted. In addition, fungal spores cannot be speciated using this method. The air sample results are included in Table 1.

All microbial samples were analyzed by PSI’s Microbiological Laboratory located in Pittsburgh, PA. The laboratory successfully participates in the American Industrial Hygienists Association (AIHA), Environmental Microbiology Proficiency Analytical Testing Program (EMPAT) which measures the laboratory’s proficiency in analyzing environmental microbiological samples.

EMPAT is specifically for labs identifying microorganisms commonly detected in air, fluids, and surface samples during fungal studies. EMPAT is a triennial performance based testing program.

Samples may contain both pure and mixed cultures of fungi or bacteria. Laboratories participate to assess and improve their analytical skills. Proficiency in EMPAT is mandatory for labs seeking EMLAP accreditation.

4. DATA ANALYSIS & INTERPRETATION

Analysis and interpretation of the data generated during the field investigation is presented in the following sections. Where appropriate, the results are compared with regulatory limits, if available, or industry standard guidelines for the chemicals, compounds, and physical measures identified in this assessment. Summaries of the analytical results are provided in Table 1.

Laboratory reports are provided in the Appendix.

4.1 OBSERVATIONS

Noticeable variations in temperatures and perceived humidity upon entry into the various areas of the building were not indicated. The air conditioner units were functioning at the time of the evaluation. Upon entry, no unusual and “musty” odors were noted. No areas of suspect visible mold amplification were observed in the building assessed. Generally, the temperature and relative humidity were within the comfortable range, as confirmed by instrument readings.

4.2 AIRBORNE SAMPLE RESULTS

There are currently no enforceable regulatory standards pertaining to air, surface, or bulk concentrations of fungi. In the absence of a regulatory standard, health and safety practitioners find guidance from the American Conference of Governmental Industrial Hygienists (ACGIH) publication of the Bioaerosols Committee entitled "Guidelines for the assessment of Bioaerosols in the Indoor Environment". The ACGIH guidelines recommend medical assessment of symptoms, evaluation of building performance and use of professional judgment as primary means for investigating indoor air quality issues. According to the ACGIH, routine air sampling is not recommended because there are no scientific supportable numerical limits to which microbial air samples may be compared.

Air sampling is best used as a means to determine if there is amplification of microorganisms within the building as compared to naturally occurring microorganisms’ outdoors. Air sampling may also be used to document the contribution of identified microorganisms and their sources to a particular air quality problem or complaint.

Molds and bacteria were identified by colony growth and microscopically as necessary. A complete listing can be found in the appendices to this report. Though never truly accurate for numbers, the air samples are accurate at detecting the types of colonies which were airborne at the time of sampling. The analytical methodology involves identification of the three most prevalent organisms in a sample.

For airborne samples, indoor levels and types were compared to the outdoor varieties with the best scenario being similar types but fewer spore counts in the indoor sample. Results for airborne total (viable and non-viable) fungi (mold) are expressed as fungal structures (spore counts) per cubic meter (spores/M3).

Air samples for total fungal spore analysis were collected from the following locations:

70’ level-Backup Radio Room

10’ Level-Communications Room

Outside of the Building.

The total spore concentration for the outdoor sample was 1,721 spores/M3. The results for the samples collected from inside the building had total spore concentrations ranging from 167 to 344 spores/M3. The spore types identified on the indoor total spore air samples were also identified on the outdoor sample.

5. CONCLUSIONS AND RECOMMENDATIONS

PSI has performed an Indoor Air Quality Assessment of the subject site in general accordance with Agreement between Parson Government Services, Inc. and PSI. Based on the results of this assessment, the following conclusions and recommendations have been developed.

5.1 PHYSICAL MEASUREMENTS/GENERAL COMFORT PARAMETERS

The assessment results indicate that the comfort parameters measured within the subject building were within the guidelines specified by ASHRAE for temperature and humidity were found to be within the referenced guidelines. Excessive moisture was not measured within the tested building material substrates.

5.2 AIRBORNE TOTAL FUNGAL SPORE COUNT RESULTS

Based on the laboratory results for the air samples collected, no elevated concentrations of fungal spores were identified in comparison to the outside sample and does not appear to be evidence of fungal amplification.

5.3 RECOMMENDATIONS

These sample results generally confirm that the total indoor spore counts were lower than what was measured outside the building, which is considered acceptable for a structure with a normally functioning heating, ventilation and air-conditioning (HVAC) system with no interior fungal amplification sources. Visible fungal growth in excess of 25 square feet was not observed, so mold remediation is not warranted at this time. It should be noted that no unusual odors were noticed upon entry into the office, there were no excessive water stains or indications of leaks in the offices, and moisture meter readings around windows and doors were in the “dry” range. PSI recommends that the door frames that have visible damage be repaired to minimize the potential for fungal amplification.

Professional Service Industries, Inc. (PSI) was retained by Parsons Government SVCS In. to conduct a lead-based paint survey of Building B1160, Lackland AFB Kelly ATCT located at Lackland AFB, Texas. The inspection was performed under the direction of Mr.

John Langan, a Texas Department of Health (TDH) Certified Lead Risk Assessor (Certificate No. 2070377). A brief summary of findings is contained in the following paragraphs.

An initial walk-through was conducted to determine the presence of accessible and/or exposed paint films. Coatings that were similar in general appearance and that appeared to have a similar painting history and substrates were grouped together for testing.

Following the walk-through, the inspector performed testing utilizing x-ray fluorescence (XRF). The 1997 Chapter 7 revisions to the U.S. HUD Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (June 1995) requires one test per testing combination unless otherwise directed. A testing combination is a unique combination of room equivalent, building component type, and substrate. Paint color is no longer a variable of testing combinations. Confirmation samples were not required hence no paint-chip samples were collected for this survey.

This survey did identify the presence of lead content above the “HUD standard” of 1.0 mg/cm2 or 0.5 percent by weight in the areas screened for LBP.

2.0 INTRODUCTION

2.1 General Information

Professional Service Industries, Inc. (PSI) was retained by Mr. Stephen Reus of Parsons Government SVCS In. to conduct a lead-based paint survey of Building B1160, Lackland AFB Kelly ATCT, located at Lackland AFB, Texas. The survey was conducted on August 21, 2014. This report has been prepared for the exclusive use of Parsons Government SVCS In..

2.2 AUTHORIZATION

This survey was completed in accordance with the agreement between PSI and Parsons Government SVCS Inc.

2.3 PURPOSE

The purpose of the lead-based paint testing was to identify painted surfaces or other surface coatings that contain 1.0 mg/cm2 lead or greater by XRF.

In 1978, the Consumer Product Safety Commission banned the sale of lead-based paint to consumers, and its application to areas where consumers have direct access to painted surfaces. Because of this ban, buildings painted prior to 1978 are suspected of containing leaded paint. However, testing has shown that leaded paint was used in many buildings painted after 1978 as well.

The information provided in this report can be used by Parsons Government SVCS In. to make decisions regarding lead management and abatement strategies or the need for additional testing.

2.4 WARRANTY

The information contained in this report is based upon the data furnished by the client and observations and test results provided by PSI. These observations and results are time dependent, are subject to changing site conditions, and revisions to federal, state, and local regulations.

PSI warrants that these findings have been promulgated after being prepared in accordance with generally accepted practices in the lead-based paint testing and abatement industry. No other warranties are implied or expressed.

PSI also recognizes that raw field test data is usually not sufficient to make all abatement and management decisions and recommends that PSI be afforded an opportunity to review abatement specifications so test results may be properly interpreted and implemented.

APPENDIX A

Background Information on Lead and Lead-Based Paint

BACKGROUND ON LEAD

Lead-based paint is defined by the EPA and HUD as “paint or other surface coatings that contain lead in excess of 1.0 mg/cm2 or 0.5% by weight.”

The U.S. Department of Health and Human Services states that lead poisoning is the most common environmental threat of young children. Lead poisoning of young children can cause brain damage that interferes with the development of intelligence.

Paint with a high lead content was widely used until 1978 when the Consumer Product Safety Commission lowered the maximum legal lead content of house paint to 0.06% by weight. It is therefore estimated that more than 75% of homes built before 1980 contain significant amounts of lead. The primary source of lead exposure in children is dust. Paint chips that are swallowed, contaminated water, and utensils with lead coating also contribute to the problem.

The exposure of construction workers is a concern because of the high levels of airborne dust on construction projects and high lead concentrations of many commercial coatings. The U.S. Occupational Safety and Health Administration (OSHA) lead in construction standard 29CRF 1926.62 applies to the construction industry. Additionally, the OSHA standard applies to the disturbance of materials coated with any detectable levels of lead.

Lead-based paint hazards can be temporarily controlled using “in-place management”. Interim control measures are intended to “reduce temporarily human exposure or likely exposure to lead-based paint hazards” as defined in Title X of the Housing and Community Development Act of 1992. Paint coatings can be maintained in good condition and managed in place until removal or renovation activities. Interim control measures are effective as long as they are carefully monitored, maintained, and periodically reevaluated.

GLOSSARY OF TERMS

Abatement - a comprehensive process of eliminating exposure or potential exposure to lead paint and lead-containing soil and dust which must include testing, measures for worker protection, containment of dust and debris, cleanup and disposal of waste, and clearance testing.

Action Level - the point at which something needs to be done to correct or eliminate the presence of the hazard (e.g. lead).

Acute Effect - severe or immediate reaction, usually to a single large exposure.

Administrative Removal - is the temporary removal of workers prior to their reaching blood lead levels requiring medical removal in order to provide additional protection to both workers and employers.

Apparent Lead Concentration (ALC) - for direct reading XRFs, is the average of at least 3 XRF single cycle readings on a painted surface. For spectrum analyzers, the ALC is a single reading.

Atomic Absorption - is a method of measuring elements such as lead. The lead is vaporized at high temperature, usually several thousand degrees, and light of a very specific wavelength is shined through the vapor.

Biological Monitoring - is the analysis of person’s blood and/or urine, to determine the level of a contaminant, such as lead, in the body.

Blank - a non-exposed sample of the medium used for testing, such as wipe or filter, which is analyzed like other samples to determine whether (1) samples are contaminated with lead before samples are collected (e.g., at the factory, or at the testing site), (2) the samples are contaminated after sample collection (e.g., during transportation to the laboratory or in the laboratory).

CFR - The Code of Federal Regulations - a codification of the regulations of the various Federal Agencies.

Characteristics - EPA has identified four characteristics of a hazardous waste:

Ignitability; Corrosivity; Reactivity; and Toxicity. Any solid waste that exhibits one or more of these characteristics is classified as a hazardous waste under RCRA.

Chelation Therapy - the medical treatment in which a drug that is attracted to metals (such as lead) is infused into a patient’s vein. The drug binds to the metal in the blood, and both are excreted by the kidney in urine.

Chronic Effect - a response to exposure which may take days, months or years to develop.

Corrected Lead Concentrations, CLC - the difference between the Apparent Lead Concentration (ALC) and the Substrate Equivalent Lead Concentration (SEL).

Common Area - a room or area that is accessible to all residents in a multi-family building (e.g., hallway, laundry room).

Containment - is a process for protecting the environment by controlling exposures to lead dust and debris created during abatement.

Detection Limit - the minimum amount of a component that a method can reliably measure.

Direct Reading XRF - is an x-ray Fluorescence analyzer which provides the operator with a display of an estimated lead concentration, usually calculated from the lead “K” x-ray intensity, but sometimes from the “L” x-ray intensity.

dI - stands for “deciliter.” The prefix “deci-” means “one-tenth.” One deciliter is roughly the same as about one tenth of a quart, or about 3.4 fluid ounces.

Dwelling Unit - refers to the room or group of rooms within residential premises used or intended for use by one family or house hold for living, sleeping, cooking and eating. “Dwelling Unit” includes a condominium.

Encapsulation - involves resurfacing or covering surfaces, and silling or caulking with durable materials, so as to prevent or control chalking, flaking lead-containing substances from becoming part of house dust or accessible to children. Painting or wallpapering is not considered to be encapsulation.

Engineering Controls - are measures implemented at the work site to contain, control and/or otherwise reduce worker exposure to, and environmental releases of, lead dust and debris.

EPA Identification Number - the unique number assigned by EPA to each generator or transporter of hazardous waste, and each treatment, storage, or disposal facility.

Final Inspection - inspection by a qualified inspector, industrial hygienist, or local public health official to determine whether abatement and cleanup are complete.

Generator - any entity who first creates a hazardous waste, or any person who first makes the waste subject to the Subtitle C regulation (e.g., imports a hazardous waste, initiates a shipment of a hazardous waste from a TSD, or mixes hazardous wastes of different DOT shipping descriptions by placing them into a single container).

HEPA or High Efficiency Particle Air Filter - means a filter capable of filtering out particles of 0.3 microns or greater from a body of air at 99.97% efficiency or greater.

High Phosphate Detergent - detergent which contains at least 5% trisodium phosphate (TSP).

In-place Management - a series of recurrent actions to reduce the lead hazard until such time as abatement can be carried out. Usually involves paint stabilization and regular cleaning of the premises.

Intact Surface - refers to a surface with no loose paint.

Landfill - a disposal facility or part of a facility where solid or hazardous waste is placed in or on land and which is not a land treatment facility, a surface impoundment, or an injection well.

Logbook - a notebook that accompanies each XRF analyzer, to record such information as daily performance, maintenance problems, and average reading time.

Manifest - the shipping document, EPA form 8700-22, used for identifying the quantity, composition, origin, routing, and destination of hazardous waste during its transportation from the point of generation to the point of treatment, storage, or disposal.

Medical Removal - the temporary removal of workers due to elevated blood levels as defined in the OSHA Lead Standard.

Micrograms - one millionth of a gram: g: The prefix “micro-” means “1/1,000,000 of” (one millionth of). Since there are 453 grams in one pound and 16 ounces in one pound, one gram equals 0.035 ounces. A microgram is equal to about 35/1,000,000 (thirty-five billionths) of an ounce.

Off-Site-Paint Removal - the removal of paint at a site away from the abatement project such as the stripping of lead paint from the surface of a component at the facilities of a commercial paint-stripping operation occurring in chemical tanks.

On-Site Paint Removal - the removal of lead-based paint down to the bare substrate usually through heat, chemical or mechanical means. The affected component remains in-place on the premises during this removal process.

Personal Samples (for sampling lead dust) - air samples collected from within the breathing zone of a worker, but outside the respirator.

Pigments - are chemicals which have color, or properties which affect color.

ppm - stands for “parts per million,” meaning the weight of one part per weight of the total amount of material. For example, a lead concentration of 1 ppm expresses the ratio of one gram of lead dissolved into one million (1,000,000) grams of water.

Precision - the degree of variation in a series of successive measurements of the same phenomenon. Commonly measured by standard deviation.

Public Housing Agency (PHA) - any State, county, municipality, or other governmental entity or public body (or agency or instrumentality thereof) which is authorized to engage or assist in the development or operation of housing for low income families.

Random Testing - the process of performing an initial survey in representative sampling of units in a project.

RCRA - Resource Conservation and Recovery Act of 1976. What we commonly refer to as RCRA is an amendment to the Solid Waste Disposal Act of 1965. RCRA was amended in 1980 and most recently on November 8, 1984 by the Hazardous and Solid Waste Amendments.

Replacement - is a strategy of abatement which entails the removal of components such as windows, doors, and trim that have lead painted surfaces and installing new components free of lead paint.

SEL (Substrate Equivalent Lead Concentration) - for a direct reading XRF, the average of at least 3 XRF single cycle readings on an unpainted surface. For a spectrum analyzer, the difference between the instrument reading on a standard or reference material placed on the bare substrate and the known lead level in the standard.

Small Quantity Generator - as defined by EPA, a generator who produces less than 100 kg of hazardous waste per month (or accumulates less than 100 kg at any one time) or one who produces less than 1 kg of acutely hazardous waste per month (or accumulates less than 1 kg of acutely hazardous waste at any one time). State definitions of Small Quantity Generator may vary.
