- Description
- Sources are being sought to perform the following (partial)Statement of Work (SOW). Business concerns who are interested in this notice can send the following info: Company name and address, point of contact, DUNS No., and previous contracts info. Send info to: Commander (fcp-4),U S Coast Guard MLCA, Attn: Romy Maglalang, 300 East Main St., Norfolk, VA 23510. Or, by email to: romeo.v.maglalang@uscg.mil; by fax: 757-628-4134/35. Purpose: Provide SECTOR Houston/Galveston with exposure data and symptom / quality of life data that will be analyzed to identify and determine the statistical significance of short and long term associations or trends that result from working inside the main administrative building. Associations or trends will include but will not be limited to: Outdoor and indoor air quality over time. The concentration ratio of outdoor and indoor airborne chemical contaminants and symptom rates over time Association between concentration ratios and quality of life indicators over time. Any combination of the above variables in relation to each other Study Design: Design will combine environmental and symptom survey data that is temporally matched. Collection of environmental data will be temporally randomized. Coast Guard will add airborne chemical environmental data to the study that is event-driven; resulting from sampling when there is a known chemical release or a significant odor is detected which signals a chemical release. One or more local Houston-area Coast Guard control populations are required; at a minimum the USCG Houston air station at Ellington Field will serve as a control. A control will allow data comparison and determination if relocation would provide a significantly different working environment. Control data can be selected from environmental, symptom and/or quality of life indicators. Data Analysis: Study data will be analyzed by an Epidemiologist or Biostatistician in conjunction with the study team. Sampling: Sampling media and/or instruments will be used to collect a sufficient volume of outdoor and indoor air over a pre-determined period and analyzed by a suitable standard methodology. Sampling will include at least two indoor and one outdoor area. Sampling will be of sufficient volume and duration to allow a limit of quantification at least equal to the exposure criteria. The duration of sampling will match the time-averaging period required by the exposure criteria. Sampling will include a suitable number of field and media blanks. Survey accomplished via the internet or by email. Questionnaire will collect building occupant symptoms, metadata, and quality of life indicators. Measures: Analysis of at least 30 chemicals by commercial or research laboratory. Chemicals must include: benzene, isopropanol, acetone, xylene, ethylbenzene, toluene, styrene, isobutane, 2-heptanone and total hydrocarbons,pyrene,naphthalene and anthracene as indicators of asphalt-based polyaromatic airborne chemicals. For a period to include the study duration, gather publicly available National Ambient Air Quality Standards data from the closest NAAQS sampling station to Section Houston-Galveston. Indoor and outdoor particulate matter concentrations by particle size as measured by Coast Guard owned TSI Dustraks.Particle size discrimination must include PM 2.5. Indoor and outdoor temperature, relative humidity, carbon dioxide and carbon monoxide. Symptom Survey: building occupants will be assigned an online survey account number and will be asked to provide one-time baseline (metadata) information (name, gender, birth date, tenure, position, physical location, work hours, etc?). Quality of Life Indicators (QLI): stress, noise, odors, etc. Building occupants will provide this information in addition to symptoms. Noise levels will be assessed during periods of peak outdoor noise associated with the activities of surrounding industrial areas. Evaluation Criteria: Evaluation criteria will include acute and chronic criteria from: Texas Natural Resources Conservation Commission (TNRCC) health-based Effects Screening Levels, ESL. ATSDR Minimal Risk Levels (MRLs). Assumptions: The outdoor air sampling location will be fixed, and close as possible to the outdoor air intake to the heating, ventilating and air-conditioning system(s).This location will be considered representative of outdoor air locations, even though concentrations of chemicals in other outdoor areas may actually be lower or higher than measured values. Indoor air sampling locations will be of a number such that they are representative of distinct areas of the building. For example, distinct floors or separate built environments within the building that house distinct populations of individuals. These locations will be considered representative of indoor concentrations of chemicals at those locations.
