1.0 - EXECUTIVE SUMMARY

Bonus Environmental, LLC was contracted by the National Guard Bureau Region North Industrial 

Hygiene office to identify and measure the existence and extent of potentially hazardous operations or 

conditions at the Washington D.C. Armory located at 2001 E. Capital Street in Washington D.C., 

20003. The purpose of this evaluation was to generate or to update a previous baseline evaluation so 

that employee exposure history can be provided to each civilian and military employee. The following 

industrial hygiene conditions were evaluated during this industrial hygiene evaluation performed by 

Bonus Environmental, LLC representatives and on September 24, 2012: 

• Indoor Air Quality

• Lead Wipe & Bulk Sampling

• Illumination

• Ergonomics 

• Evaluation of the physical condition of 

the facility in regards to peeling paint, 

asbestos containing materials, water 

damage or mold problems, and 

housekeeping practices.

The Washington D.C. Armory is an Army National Guard armory comprised of offices, classrooms, 

locker rooms, storage rooms, a drill hall, a gym, bunk rooms, break rooms, and conference rooms. The 

point of contact for the approximately 588,000 ft2 Washington D.C. Armory is SPC James Harrison. 

Two hundred fifty eight (258) full-time administrative personnel and eleven (11) maintenance 

personnel are employed at the Washington D.C. Armory. A shop diagram depicting the locations of 

the operations identified during this industrial hygiene evaluation is not provided, as the floorplans 

provided to Bonus Environmental, LLC are so large that they aren’t able to be reduced to a reasonable 

size and remain readable.

The National Guard Bureau Region North Industrial Hygiene Office provided governmental furnished 

equipment and sampling media required to perform the industrial hygiene evaluation. Chain of 

custody forms for laboratories approved by the National Guard Bureau Region North Industrial 

Hygiene Office were provided with the sampling media. All samples collected during this industrial 

hygiene evaluation were sent to the National Guard Bureau Region North Industrial Hygiene Office 

approved laboratories for analysis.

2.0 – LEAD SAMPLING

2.1 – Lead Wipe Sampling

Lead wipe sampling was performed according to the Environmental Protection Agency (EPA) method 

600/R-93/200(M)-7420 (Atomic Absorption - Flame). Nineteen (19) wipe samples and one (1) field 

blank were sent under chain-of-custody procedures to AMA Analytical Services, Inc., an American 

Industrial Hygiene Association (AIHA) accredited laboratory located in Lanham, Maryland. The U.S. 

Department of Labor (USDOL) and the Occupational Safety and Health Administration (OSHA) do 

not have a promulgated standard for lead surface contamination; however OSHA has provided an 

interpretive level of 200 micrograms per square foot (μg/ft2) to assess the housekeeping requirements 

of "as free as reasonably practicable". This interpretation is presented in OSHA Industrial Hygiene 

Technical Manual (TED 01-00-015; 1/20/1999), and in a letter of interpretations dated 1/13/2003, and 

subsequently issued to public domain. NG Pam 420-15 addresses the conversion and remediation of 

former indoor firing ranges. The following table outlines the locations and analytical results for the 

lead wipe samples collected during this project

The former indoor firing range is currently used for storage. It is uncertain whether it was remediated 

to the protocols specified in NG Pam 420-15. Remediation wipe sample results were not posted, nor 

were any signs posted restricting access to the area. The bullet trap was not still in the “bullet trap 

area”.

3.0 - PHYSICAL CONDITION OF FACILITY / PERSONNEL CONCERNS 

3.1 - Lead Based Paint 

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

performed a visual inspection of the facility in regards to lead based paint. Bonus Environmental, LLC 

identified several areas of peeling paint which could potentially pose a lead exposure hazard. Bonus 

Environmental, LLC identified peeling blue paint in the ground floor, east hallway, and peeling white 

paint in the Boiler room, on the upper west wall. Two (2) paint chip samples was collected and sent 

under chain-of-custody procedures to AMA Analytical Services, Inc., an AIHA accredited laboratory 

located in Lanham, MD. Analysis indicated that both of the peeling paints collected contained

detectable levels of lead. The paints are therefore considered to be lead-based paint. The OSHA Lead 

in Construction Standard, 29 CFR 1926.62 does not assign a numerical value of which must be present 

within the paint to be considered lead based paint. Paints which contain any detectable level of lead 

shall be treated and handled as lead based paint. Housing and Urban Development (HUD) defines lead 

based paint as having greater than 0.5% lead by weight. Paint chip sample results are attached to this 

report as Appendix A. 

3.2 – Presumed Asbestos Containing Materials 

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

performed a visual inspection to identify presumed asbestos containing materials (PACM) and, if 

found, to note their condition. Bonus Environmental, LLC did not identify any PACM that was 

considered to be in poor or damaged condition. 

3.3 - Water Damage/Mold Growth 

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

performed a visual inspection to report the location and perform an evaluation of any water damaged 

or visible mold problems. Bonus Environmental, LLC identified approximately 8 ft2 of waterdamaged dropped-ceiling tiles, and approximately 60 ft2 of moldy drywall located in Room 119 

(Maintenance Room). In addition, it was noted that Room 12-W was labeled with signs as “Microbial

Page 6 of 44
Hazard”. Room 12-W was stripped of it’s walls to the studs on it’s perimeter wall, and had waterstained carpeting.

3.4 - Housekeeping

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

performed an evaluation of the housekeeping practices. Bonus Environmental, LLC found the 

housekeeping practices within Washington D.C. Armory facility in good order. 

3.5 – Employee Interviews

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

performed interviews and made observations to determine if the work activities being performed 

possessed any ergonomic concerns. Following the interviews and observations, no ergonomic and or 

indoor air quality concerns were identified. 

3.6 – Indoor Air Quality

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

measured temperature, relative humidity, carbon monoxide (CO), and carbon dioxide (CO2) 

throughout the facility. A calibrated TSI Q-Trak Plus Model 8554 Indoor Air Quality Monitor

equipped with a Q-Trak Probe 982 was utilized to record indoor air quality measurements. 

Carbon dioxide is a natural component of air and the amount of CO2 in a given air sample is 

commonly expressed as parts per million (ppm). The outdoor air in most locations contains about 380 

ppm carbon dioxide. Higher outdoor CO2 concentrations can be found near vehicle traffic areas, 

industry and sources of combustion. The concentrations of CO2 found in most offices are well below 

the OSHA Permissible Exposure Limit (PEL) of 5,000 ppm when averaged over an 8-hour time period 

for an industrial workplace. While levels below 5,000 ppm are considered to pose no serious health 

threat, studies have indicated that individuals in offices with elevated CO2 concentrations tend to report 

drowsiness, lethargy and a general sense that the air is stale. Ventilation rates for office spaces are 

defined by various codes and standards. The most widely accepted standard is the American Society 

of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Standard 62. According to 

ASHRAE Standard 62.1-2010, CO2 concentrations below 700 ppm above the outdoor level are 

considered to indicate adequate ventilation and provide human comfort. The CO2 measurements 

collected during this industrial hygiene evaluation ranged from 368 ppm to 684 ppm and indicate 

adequate ventilation within the facility.

Carbon monoxide is a colorless, odorless, poisonous gas that results from the incomplete burning of 

common fuels such as natural or liquefied petroleum gas, oil, wood or coal. When carbon monoxide is 

inhaled, it enters the blood stream and reduces the ability of the blood to carry oxygen to vital organs, 

such as the heart and brain. Because it is impossible to see, taste or smell the toxic fumes, CO can 

harm you before you are aware it is in your work area. At lower levels of exposure, CO causes mild 

effects that are often mistaken for the flu. These symptoms include headaches, dizziness, 

disorientation, nausea and fatigue. The effects of CO exposure can vary greatly from person to person 

depending on age, overall health and the concentration and length of exposure. The OSHA has 

established a permissible exposure limit (PEL) of 50 parts per million (ppm). OSHA standards 

prohibit worker exposure to more than 50 parts of the gas per million parts of air averaged during an 8-

Page 7 of 44
hour time period. The peak CO level for employees is 200 ppm. The CO measurements collected 

during this industrial hygiene evaluation ranged from 0.0 ppm to 0.8 ppm. CO levels were well below 

the OSHA PEL during this industrial hygiene evaluation. 

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

collected temperature measurements. Temperature measurements throughout the common areas of the 

facility routinely occupied by employees ranged from 68.7oF to 74.1oF and are considered to be within 

an acceptable range outlined within ASHRAE Standard 55-2010. 

During the industrial hygiene evaluation of the Washington D.C. Armory, Bonus Environmental, LLC 

collected relative humidity measurements. Relative humidity measurements throughout common areas 

of the facility routinely occupied by employees ranged from 28.3% to 45.3%. Indoor air quality 

measurements recorded during this industrial hygiene evaluation are summarized in the table below.

SECTION 1.0 PROJECT OVERVIEW & SUMMARY

On June 30, 2014, an Industrial Hygiene Investigation was conducted at the DC 

Armory Readiness Center (RC). Mr. of LEA Environmental LLC 

(LEA) conducted the investigation. The site contacts for the survey were Safety 

and Occupational Health Specialists, CIV, DCARNG and SPC, 

DCARNG . LEA was contracted to perform an evaluation of the 

subject facility following standard guidelines and protocols as well as to 

identify any immediate concerns to environmental health & safety. The 

evaluation included the following activities: 

• A general overview of the activities performed during the workday was 

conducted, including interviews with site representatives for background 

information. 

• An evaluation of the ventilation system was conducted. 

• Direct reading instrumentation was utilized to measure common indoor 

air quality parameters including temperature, relative humidity, carbon 

dioxide and carbon monoxide. 

• A lighting evaluation was conducted in the warehouse and the adjacent 

office spaces. 

• An on-site review of the site-specific written compliance programs was 

conducted. 

• A building survey was conducted for identification of potential 

hazardous building materials (mainly potential peeling lead-based paint 

and potential asbestos containing materials) was conducted. Samples 

were collected and sent to an appropriately accredited laboratory for 

analysis. 

• Sampling for lead was conducted using ghost wipes for the potential 

cross contamination of lead. Samples were collected and sent to an 

appropriately accredited laboratory for analysis. 

• Air sampling was conducted to determine the presence of lead in the air. 

Samples were collected and sent to an appropriately accredited 

laboratory for analysis. 

• An evaluation of the personal protective equipment utilized by workers 

during the course of the work activities was conducted. 

• Photographic documentation was collected in the facility. 

It should be noted that based on interviews with the site point of contact, not 

all rooms were accessible and there was no access to the 3rd Floor North 

(Generals’ Floor). 

During the course of the investigation, an area of water intrusion was noted in 

room 105-A. Water damage on ceiling tiles and radiator pipe wrap was 

observed. A sample (P-2) was collected of the pipe wrap and analyzed for the

presence of Asbestos Containing Materials (ACM). Results of the sample 

analysis indicated no ACM detected. 

In addition, peeling paint was observed at the basement level of stairwell 11-L1, 

which appeared to be the direct result of a previous water intrusion event that 

occurred in the basement floor of the facility. Peeling paint was also observed 

in room 303E, currently being renovated. Samples P-1 and P-3 were collected 

and analyzed for lead. Results indicated lead levels below the recommended 

limit for classification as “Lead Based Paint”. 

At the time of the investigation the POC of the DC Armory indicated an air 

quality complaint in a small closet housing gas masks and field bags (Room 

105-2). An investigation of the area was conducted and observations and direct 

reading instrumentation did not indicate an immediate concern to 

environmental health and safety. 

In addition, the POC indicated a mold complaint was noted in a double shower 

(Room 5-SB) and a women’s restroom (Room 10-SB). Room 5-SB was previously 

cleaned and no visible mold growth was observed. Visible mold growth was 

observed in Room 10-SB on the ceiling tile where visible watermarks were also 

observed. 

The lighting survey was conducted throughout the facility offices. The results 

of the survey revealed that several areas demonstrated illumination levels that 

were below the recommended minimums. It should be noted that based on the 

size and access of the facility, all rooms could not be investigated. In addition, 

there was no access to the 3rd floor north corridor. 

The on-site review of written compliance programs found the programs 

supplied complete, with attached documentation of employee training. 

During the survey, inspection dates on portable fire extinguishers were checked 

and were found to be current. 

Based on the operations of the facility, a chemical inventory and Material Safety 

Data Sheets were not noted during the course of the survey.

SECTION 3.0 PROJECT DISCUSSION

Upon completion of the survey, and receipt of sample results, the information 

obtained is researched and compared against applicable standards. Any 

observations made by the Industrial Hygienist during the course of the survey 

are added to the interpretation to understand any possible abnormalities. The 

following outlines the results for the individual parameters selected for 

monitoring, and information on the applicable regulations and/or guidelines 

researched. 

Section 3.1 Temperature & Relative Humidity 

Levels of temperature and relative humidity measured during the course of the 

investigation were compared to the American Society of Heating, Refrigerating

and Air Conditioning Engineers (ASHRAE) published guidelines. The guidelines 

prepared by ASHRAE are represented in the following chart: 

Relative Humidity Winter Temperature Range Summer Temperature Range

30% 68.5 - 76.0 F 74.0 – 80.0 F 

40% 68.5 - 75.5 F 73.5 – 79.5 F 

50% 68.5 - 74.5 F 73.0 – 79.0 F 

60% 68.0 - 74.0 F 72.5 – 78.0 F 

Based on studies conducted by ASHRAE, the published standard reflects the 

levels where 80% of building occupants are comfortable. 

The temperature levels in the AASF facility ranged from 75.3°F to 83.8°F, and 

slightly above the range as described by ASHRAE. The relative humidity levels 

ranged from 46.0% to 65.2% in the subject space. Relative humidity levels were

also slightly above recommended levels in some areas. A complete charting of 

the measurements is included in Section 4.1.

Section 3.2 Carbon Dioxide

Levels of carbon dioxide in an office space are often measured in order to 

determine the efficiency of ventilation systems in the building. Elevated levels 

of carbon dioxide can often indicate inadequate ventilation based on the 

number of occupants in a space. ASHRAE has outlined ventilation 

BEST AVAILABLE COPY BEST AVAILABLE COPY FOIA Requested Record #J-15-0085 (DC) 

Released by National Guard Bureau 

Page 32 of 44
DC ARMORY RC

INDUSTRIAL HYGIENE EVALUATION 8

requirements for office spaces, as well as provided guidelines for limits of 

carbon dioxide in a space. A conservative guideline provided by ASHRAE is that 

carbon dioxide levels remain below 1,000 ppm. In addition, as outdoor levels 

of carbon dioxide often directly impact indoor levels, ASHRAE also 

recommends a secondary guideline of indoor levels remaining below outdoor 

levels plus 700 ppm. In addition to ventilation indicators, excessive carbon 

dioxide levels can also exhibit adverse conditions in occupants such as 

headaches and lethargy. As the facility in question was noted to have 

limitations of the ventilations systems present, these measurements could be 

utilized to determine an immediate need for increased ventilation, if applicable. 

The carbon dioxide levels measured in the subject spaces of the AASF facility 

ranged from 488 ppm to 895 ppm. These levels were below the more 

conservative ASHRAE recommendation. A complete charting of the 

measurements is included in Section 4.1.

Section 3.3 Carbon Monoxide

Carbon monoxide is a common indoor air quality contaminant, resulting from 

incomplete fuel combustion in furnaces and generators, as well as through 

automobile exhaust and tobacco smoke. Levels of carbon monoxide in an 

interior working environment can also indicate improper idling of vehicles, 

such as trucks, near the facility or in the maintenance bays during normal work 

operations. 

Carbon monoxide is a colorless and odorless gas that causes the formation of 

carboxyhemoglobin in the blood stream. At moderate levels, this can cause 

angina, impaired vision and reduced brain function. In indoor spaces, various 

agencies have established indoor limits for carbon monoxide. However, a 

commonly referenced standard is the National Ambient Air Quality Standard 

(NAAQS) of 9 ppm for an eight-hour exposure limit. The levels of carbon 

monoxide ranged from 0.1 ppm to 1.3 ppm in the subject space, and below the 

recommended limit. A complete charting of the measurements is included in 

Section 4.1.

Section 3.4 Ventilation Survey 

At the time of the inspection the majority of the facility did not have a 

centralized HVAC unit, but utilized individual window air-cooling units. Heat 

for the facility was supplied via oil/boiler. Overhead exhaust and ceiling fans 

were observed in the drill hall. A portion of the second floor that has recently 

been renovated utilizes a central HVAC system. According to the POC and 

several employees at the facility ventilation and air circulation is an ongoing 

problem and complaint at the facility.

Page 33 of 44
DC ARMORY RC

INDUSTRIAL HYGIENE EVALUATION 9

In addition to the collection of direct reading measurements in the subject 

space, smoke tubes were utilized to document the direction of airflow in the 

facility. The smoke tube testing revealed that most of the areas in the facility 

revealed a “neutral” response, with limited directionality or movement from the 

point of origin. 

Section 3.5 Lighting Survey 

A lighting survey was conducted in the office areas and the drill hall. Due to 

the size and number of rooms in the facility all of the rooms could not be 

surveyed. The measurements were documented in footcandles (fc), and were 

compared against the recommended guidelines in both the ANSI guidelines for 

Office Lighting and Industrial Lighting. The results of the survey revealed that 

lighting levels ranged from 4.5 fc (Drill Hall North) to 122.9 fc (Room 107E). 

Illumination levels throughout the facility should be addressed to remain above 

recommended minimums. A complete listing of the sample results is included 

in Section 4.3. 

Section 3.6 Surface Lead Sampling

Samples were collected for the potential presence of lead on surfaces. The 

surface samples were collected utilizing SKC Ghost Wipes. The surface samples 

were collected in and adjacent to the former indoor firing range and areas 

located within the drill hall as well as offices throughout the facility where a 

potential cross contamination may be of concern. 

Results of the sampling revealed levels of lead on surfaces above the Housing 

and Urban Development (HUD) regulatory limits in samples G-2 (Pistol Range 

Floor), G-7 (Drill Hall Brick Wall), G-8 (Drill Hall Exhaust Vent), G-9 (Drill Hall 

Return Vent), and G-10 (Room 107E Window Sill). A summary of the results is 

included in Section 4.4 

Section 3.7 Potential Hazardous Building Materials Survey 

During the course of the evaluation, a visual inspection was conducted to 

determine the potential presence of hazardous building materials, such as 

asbestos or lead containing materials. In addition, the visual inspection 

includes identification of potential avenues of water intrusion that may lead to 

the amplification of microbial growth. 

During the course of the evaluation, peeling paint was observed in stairwell 11 

L-1 and on the ceiling of room 303E currently being renovated. Paint chip 

samples were collected for lead analysis. The results of the samples indicated

INDUSTRIAL HYGIENE EVALUATION 10

lead levels below the regulatory limit. A summary of the results is included in 

Section 4.5. 

A mold complaint was noted by the POC in a double shower (Room 5-SB) and a 

women’s restroom (Room 10-SB). Room 5-SB was previously cleaned and no 

visible mold growth was observed. Visible mold growth was observed in Room 

10-SB on the ceiling tile where visible watermarks were also observed. 

At the time of the investigation the POC indicated an air quality (odor) 

complaint from an employee working adjacent to Room 105-2, a small closet 

that houses gas masks and field bags. An investigation of the area was 

conducted and observations and direct reading instrumentation within the 

small closet did not indicated an immediate concern to environmental health 

and safety. 

During the investigation, a sample was collected of a material identified as 

suspected to contain asbestos. The sample (P-2) collected was pipe insulation 

located in Room 105A that was damaged following a water intrusion event. The 

bulk sample was collected following guidelines established by AHERA. The 

sample was collected and sent to an appropriately accredited laboratory for 

analysis. Results of the sample indicated no asbestos containing material 

detected. A summary of the results is included in Section 4.6. 

Section 3.8 Lead in Air Sampling

During the course of the evaluation, air samples were collected on a PVC 

filtered cassette, and analyzed at an appropriately accredited laboratory for 

lead via EPA 600. 

Samples were collected in the former firing range and drill hall as 

recommended in the ARNG Scope of Work. Results of the samples indicated 

levels of lead were below the OSHA Regulatory limit of 0.05 mg/m3

. A summary 

of the results is included in Section 4.7. 

Section 3.8 Written Compliance Program Evaluations/Chemical Inventories 

During the course of the survey, an on-site review of documentation provided 

by the site contact occurred, to include site-specific written compliance 

programs. The following written compliance programs were found in the 

documentation: 

• Hazard Communication Training 

• Fire Protection Training 

• Hearing Conservation Program

The programs were found to have been complete and subsequent training 

documentation was attached to verify the worker’s completion of the training. 

In addition, interviews with the site representatives confirmed that related 

safety training is completed in house on a quarterly schedule. The records 

found confirmed this statement. 

The facility did not have a Respiratory Protection Program or Confined Space 

Entry Program. When discussed with the site POC, it was reported that the 

facility does not require these programs. 

Section 3.9 General Observations & Work Activities 

The DC Armory Readiness Center consists of one large three-story building and 

one sub-floor (basement). Construction of the facility was reportedly 

completed in 1941. The facility consists mainly of department and support 

staff offices, ancillary storage rooms and corridors, and a 10,000-seat drill hall. 

The armory is utilized Monday thru Friday by full time Guard personnel. The 

facility supports and maintains ongoing DCARNG missions as well preparing 

units for drill weekends, occurring two weekends out of the month. The drill 

hall is utilized by the DCARNG and the DC Area for various events. There is 

usually an event held at least once a month on the drill floor, however, it may 

not necessarily be a Guard sponsored event. The drill floor, when used 

by DCARNG, can host small events such as troop deployment ceremonies, 

promotion ceremonies, and retirement ceremonies. The drill floor is also used 

for unit events in which all full time personnel are required to attend and the 

entire floor is used, as well as for memorial services for deceased soldiers. 

On the day of the survey, there was approximately 300 staff at the facility. A 

diagram of the facility as provided by the POC is included in Appendix A.
