The Contractor is expected to provide sample analysis results to the overall WTC database in a format compatible with the selected format at no additional cost.

Site ES&H Director reserves the right to reject data not meeting Data Quality Objectives at no cost to the project. Site ES&H Director reserves the right to audit the Contractor facility and procedures. Deficiencies between stated qualifications and audit results will be corrected at no cost to the project.

Required Site Monitoring Site monitoring is required under the following conditions. • When required by the Subcontract, or task-specific HASP • When required by specific OSHA standards (e.g., asbestos, benzene,, lead,, carbon monoxide) • When worker exposure is reasonably anticipated to be greater than 50% of the OSHA Permissible Exposure Limit (PELs), ACGIH TLV, or other recognized occupational exposure limit • When necessary to verify the adequacy of hazard control measures and/or personal protective equipment, including respiratory protection • When necessary to assess and evaluate worker exposure, or to resolve worker complaints or concerns. With the approval of the site ES&H Director, site monitoring may be discontinued, after representative initial monitoring is conducted and worker exposures are shown to be adequately controlled through the use of engineering, work practice, or personal protective equipment control measures. If work activities change so that the initial monitoring is no longer representative of worker exposure, monitoring must be reinitiated.

Monitoring Strategy The Contractor is expected to submit to the site ES&H Director an employee-Monitoring Plan that will provide the required information to identify and control workplace hazards. . Where monitoring is required, the Contractor shall develop and implement a monitoring program that considers the factors that may affect worker exposure and the following elements. • Monitoring requirements, contaminants, and monitoring equipment limitations • Subcontractor-specific work locations, work activities, work practices, personnel, and equipment to be used on site • Any additional site-specific hazard information gathered by the Subcontractor during development of the task-specific HASP
