If the monitoring required by paragraph (e)(2)(i) of this section reveals employee exposure above the TWA, the employer shall repeat such monitoring for each such employee at least every six (6) months.
1910.1028(e)(3)(iii)
The employer may alter the monitoring schedule from every six months to annually for any employee for whom two consecutive measurements taken at least 7 days apart indicate that the employee exposure has decreased to the TWA or below, but is at or above the action level.
1910.1028(e)(3)(iv)
Monitoring for the STEL shall be repeated as necessary to evaluate exposures of employees subject to short term exposures.
1910.1028(e)(4)
