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) At MFA Bio Fuel:  Employees are exposed to noise levels higher than 85 dBA.  The employer failed to establish a Hearing Conservation Program.    (1)  An employee working at MFA Bio Fuel was exposed to continous noise level at 105.2 % of the allowable 8-hour time-weighted average sound level of 90 dBA or an equivalent sound level of approximately 90.37 dBA.  The sampling was performed for 458 mins during one shift on August 15, 2013; exposure calculations included a zero increment for the 22 minutes not sampled.
