contaminants (dust, metals, volatile organic compounds, and other specific compounds) heat stress, cold stress and noise.

Federal, EPA, NIOSH, and New York City DDC may determine minimum site monitoring requirements. Contractors are expected to conduct exposure monitoring for all employees as required by OSHA or local requirements. All exposure data must be provided to the DDC ES&H Department.

2.4.1 Required Site Monitoring

Site monitoring is required under the following conditions. • When required by specific OSHA standards (e.g., asbestos, benzene, , lead, formaldehyde, 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 DDC/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.

2.4.2 Monitoring Strategy

The construction/demolition contractor is expected to submit to the DDC/Site ES&H Director an employee-monitoring plan that reflects the anticipated task specific hazards. Where monitoring is required, the DDC IH 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 • Contractor-specific work locations, work activities, work practices, personnel, and equipment to be used on site • Any additional site-specific hazard information gathered by the contractor during development of the task-specific JHA.

The monitoring strategy shall be documented in the task-specific JHA and include the type of monitoring (direct reading, personal, perimeter or area monitoring), activities or locations to be monitored, contaminants, monitoring instrumentation, monitoring methods, and frequency of monitoring as appropriate.
