STATEMENT OF WORK (SOW)

Department of the Interior (DOI) Analytical Laboratory Services in Support of Wildland Fire

Occupational Safety and Health (OSH) Hazard Exposure Assessment

March 10, 2026

1.0 GENERAL INFORMATION

1.1 Description of Work:

The Contractor shall provide accredited industrial hygiene and environmental laboratory analytical services (as applies to hazard determination, human exposure assessment, and hazard mitigation actions) to support air and other media testing/sampling for the purposes of wildland firefighter hazard exposure assessments. These assessments are critical to perform occupational safety and health program requirements across firefighter operations. All work will be performed in calendar year 2026 and involves an especially large, planned sampling effort (~2,000 samples) for critical assessments of current mitigations and the need and feasibility of respiratory protection for future use. All work shall ensure legally defensible, high-quality analytical data for air samples collected by government personnel or government-authorized contractors.

1.2 Background Information:

The U.S. Wildland Fire Service streamlines wildfire prevention, response, and recovery efforts across public lands administered by the U.S. Department of the Interior (DOI), setting the nation on a course to build a more resilient future. This unified service reflects the critical role Interior’s wildland fire management plays in safeguarding lives, communities, infrastructure, and ecosystems amid the increasing risk wildfires pose across the country.

The Wildland Fire Service is leading efforts to assess occupational exposures and implement medical surveillance programs for wildland firefighters. This SOW supports the 2026 initiative to conduct detailed exposure monitoring and develop effective control strategies by providing the laboratory analysis necessary to accurately quantify exposures. Development of sampling strategies, collection of samples in the field, and summary data analysis will be done by government personnel or by other industrial hygiene professionals contracted through means beyond this contract.

1.2.1 Exposure Assessment Overview

Exposure assessments are required under DOI OSH policy, Occupational Safety and Health Administration’s (OSHA) General Industry and Construction standards, and the DOI Departmental Manual (DM) Series 27. They provide a structured process to:

• Identify potential airborne and surface hazards in the workplace

• Quantify worker exposures through sampling and validated laboratory analytical methods

• Determine risk and validate effectiveness of controls through comparison of results to OSHA Permissible Exposure Limits (PELs) and the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) as required in DOI DM Part 485 Chapter 4, Safety and Health Standards, Procedures, and Guidelines.

• Recommend mitigation strategies, engineering controls, personal protective equipment (PPE) to include respiratory protection, and risk communication requirements

• Have a baseline to use as a reference when assessing other similar exposures or when evaluating the effectiveness of controls after mitigations have been implemented

• Document exposure histories as part of worker notification requirements

• Provide accurate, defensible laboratory data to support medical surveillance and program evaluation

1.3 Scope of Services

The Contractor shall provide laboratory analysis following standardized, accredited methodologies for hazard determination and exposure assessment purposes. Samples will be collected by government personnel or their contracted support industrial hygiene personnel. This contract will not be responsible for any collection of samples or any follow-on statistical analysis, reporting of results to workers, or risk assessment beyond providing the results of the laboratory analysis to the industrial hygiene staff requesting the analysis.

The lab should only provide analysis that is within the scope of the American Industrial Hygiene Association Laboratory Accreditation Program (AIHA LAP) or other accrediting body oversight when AIHA isn’t not provide coverage for the given methods. For example, Environmental Protection Agency (EPA) methods outside the scope of AIHA LAP can be accredited through the EPA’s Environmental Laboratory Accreditation Program (ELAP).

General services the laboratory will provide are:

• Receipt and management of samples under secure chain of custody

• Analytical testing using validated OSHA, National Institute for Occupational Safety and Health (NIOSH), EPA, or approved equivalent methods

• Supplying sample equipment, supplies, and media for analysis as an optional addition to analysis

• Quality control, reporting, data formatting, and electronic deliverables

• Providing results within specified timeframes

• Consultation on method selection when requested

2.0 Technical Requirements

2.2 Analytical Methods Required

The Contractor shall use validated OSHA, NIOSH, EPA, or equivalent methods as needed to support DOI and United States Forrest Services (USFS) occupational exposure monitoring. The contractor may make modifications to those standard methods as long as relevant laboratory accreditation requirements are met and they provide standard operating procedures (SOPs) describing those modifications upon request.
