Exposure monitoring and measurement.

(1) Monitoring program.
(a) Each employer who has a place of employment where coke oven emissions are present must monitor employees employed in the regulated area to measure their exposure to coke oven emissions.
(b) The employer must obtain measurements which are representative of each employee's exposure to coke oven emissions over an eight-hour period. All measurements must determine exposure without regard to the use of respiratory protection.
(c) The employer must collect full-shift (for at least seven continuous hours) personal samples, including at least one sample during each shift for each battery and each job classification within the regulated areas including at least the following job classifications:
(i) Lidman;
(ii) Tar chaser;
(iii) Larry car operator;
(iv) Luterman;
(v) Machine operator, coke side;
(vi) Benchman, coke side;
(vii) Benchman, pusher side;
(viii) Heater;
(ix) Quenching car operator;
(x) Pusher machine operator;
(xi) Screening station operator;
(xii) Wharfman;
(xiii) Oven patcher;
(xiv) Oven repairman;
(xv) Spellman; and
(xvi) Maintenance personnel.
(d) The employer must repeat the monitoring and measurements required by subsection (1) of this section at least every three months.
(2) Redetermination. Whenever there has been a production, process, or control change which may result in new or additional exposure to coke oven emissions, or whenever the employer has any other reason to suspect an increase in employee exposure, the employer must repeat the monitoring and measurements required by subsection (1) of this section for those employees affected by such change or increase.
(3) Employee notification.
(a) The employer must notify each employee in writing of the exposure measurements which represent that employee's exposure within five working days after the receipt of the results of measurements required by subsection (1) and (2) of this section.
(b) Whenever such results indicate that the representative employee exposure exceeds the permissible exposure limit, the employer must, in such notification, inform each employee of that fact and of the corrective action being taken to reduce exposure to or below the permissible exposure limit.
(4) Accuracy of measurement. The employer must use a method of monitoring and measurement which has an accuracy (with a confidence level of 95%) of not less than plus or minus 35% for concentrations of coke oven emissions greater than or equal to 150 Ug/m3.
