29 CFR 1910.95(c)(1): The employer did not administer a continuing, effective hearing conservation program as described in 29 CFR 1910.9(c) through (o) whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level of 85 decibels measured on the A scale, or equivalently a dose of fifty percent:    a) Entire Facility:  Range Safety Officers (RSOs) who were observing/instructing customers shooting inside the shooting range were exposed to noise levels in excess of the OSHA Permissible Exposure Limit of 90 dBA on 5/12/18.  Employees were exposed to continuous noise levels ranging from 91.1 dBA to 100.7 dBA as an 8-hour Time Weighted Average (TWA), which was equivalent to 117.9% to 441.2% of the Permissible Exposure Limit.   The sampling times ranged from 365 minutes to 480 minutes and zero exposure was assumed for the unsampled period of time.  The employee did not develop and implement an effective hearing conservation program; on or about 5/12/18.

29 CFR 1910.1025(c)(1): Employee(s) were exposed to lead at concentrations greater than fifty micrograms per cubic meter of air averaged over an eight-hour period:    a) Inside the Shooting Range:  On or about 5/12/18, two range safety officers (RSOs) who observed/instructed customers and performed cleaning in the range were exposed to lead levels ranging from 143 ug/m3 to 507 ug/m3 (micrograms of lead per cubic meter of air) which was between 2.86 and 10.14 times above the OSHA 8-Hour Time Weighted Average Permissible Exposure Limit of 50 ug/m3.  The sampling time ranged from 320 minutes to 460 minutes and zero exposure was assumed for the unsampled period of time.     b) Inside the Shooting Range:   On or about 6/18/18, a Range Safety Officer (RSO) who performed cleanup of the range through dry sweeping, shoveling and vacuuming of lead debris was exposed to 88 ug/m3 (micrograms of lead per cubic meter of air) which was 1.77 times above the 8-Hour Time Weighted Average Permissible Exposure Limit of 50 ug/m3.  The sampling time was for 65 minutes and zero exposure was assumed for the unsampled period of time.    MULTI-STEP ABATEMENT PLAN:    Step 1: Provide effective respiratory protection and ensure it is used by exposed employees as an interim protective measure until feasible engineering and/or administrative controls can be implemented or whenever such controls fail to reduce employee exposure to within permissible exposure limits.       Step 2: A written detailed plan of abatement shall be submitted to the Area Director outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposures to hazardous substances as referenced in this citation.  This plan shall include, at a minimum, target dates for the following actions which must be consistent with the abatement dates required by this citation:            (1)  Evaluation of engineering /administrative control options;       (2)  Selection of optimum control methods and completion of design;       (3)  Procurement, installation and operation of selected control measures;       (4)  Testing and acceptance or modification/redesign .
