29 CFR 1926.62(e)(1): The employer did not implement all feasible engineering and work practice controls, including administrative controls, to reduce and maintain employee exposure to lead to or below the permissible exposure limit: Decommissioned Millstone Power Station Unit No. 1 Roof: On or about October 24, 2023, and sometime thereafter, employees were presumed to be exposed to lead during high exposure plasma torch cutting tasks at concentrations greater than fifty micrograms per cubic meter of air (50 ug/m3) over an averaged 8-hour period. The employer did not implement feasible engineering and work practice controls that included, among others, local exhaust ventilation and stripping back lead-containing coating to reduce employee exposure presumed to be in excess of 2,500 ?g/m3 for the "trigger tasks" tasks listed in paragraph (d)(2)(iv) when employees were presumed to be exposed to excess levels in the absence of monitoring required per 29 CFR 1926.62(d), which verifies that employees were not exposed to levels that exceeded the 2,500 �g/m3 lead concentration levels for the (d)(2)(iv) "trigger tasks" performed. . This occurred while employees used a plasma cutter and power cutting tools to aggressively cut lead-painted building structures that included, but were not limited to, boiler system piping; roof penetrations, electrical conduits, air handling recirculation units (HVHs), exhaust filter fan units (HVEs), and ductwork that was removed from some of the following rooftop Millstone Power Station Unit 1 locations: a) Maintenance Shop Roof b) Turbine Building Roof c) Reactor Building Roof d) Yard - Radwaste & Radwaste Storage Roof
