General-duty citation text

29 CFR  1926.1126(d)(3): The employer did not determine the 8-hour time-weighted average exposure for each employee on the basis of any combination of air monitoring data, historical monitoring data, or objective data sufficient to accurately characterize employee exposure to chromium (VI):  a.  On or about February 10, 2021, the employer had relied on historical air monitoring data from previous project worksites in 2009 and 2015 with follow-up air monitoring in 2016 and 2017.   The 2009 air monitoring report indicated that weather conditions were abnormal the day of monitoring and, therefore, should be repeated. The employer completed air monitoring in mid-February 2015 where 4 of 14 results obtained indicated employee exposures of 66.7, 674, 134, and 711 �g/m3, which were above the OSHA PEL of 5 �g/m3.  The employer repeated air monitoring at the end of Feb 2015, which indicated an employee exposure of 13 �g/m3, and again in December 2016, which indicated employee exposures of 9.3 �g/m3 and 22 �g/m3.  Monitoring in January and February 2017 was also obtained with one employee exposure 3.4  �g/m3, which was above the OSHA Action Level of 2.5  �g/m3.  No air monitoring had been completed by the employer at the Guernsey Power Station worksite prior to February 10, 2021.
