(2) Demarcation The regulated area shall be demarcated in any maimer that minimizes the number of persons within the area and protects persons outside the area from exposure to airborne ~ - and their removal procedures, and other practices for reducing the hazard. Such training shall be obtained in a comprehensive course, such as a course conducted by an EPA Asbestos Training Center, or an equivalent course.

(5) Prohibited activities. The employer shall ensure thal employees do not eat. drink, smoke, chew tobecco or gum. or apply cosmetics in the regulated area. (ii) Determinations of employee exposure shall be made from breathing zone air samples that are representative of the 8-hour TWA of each employee. (iii) Representative 8-hour TWA employee exposure shall be determined on the basis of one or more samples representing full-shift exposure for employees in each work area. (2) initial monitoring, (i) Each employer who has a workplace or work operation covered by this standard, except as provided for in paragraphs (f)(2)(u) and (f)(2)(iii) of this section, shall perform initial monitoring at the initiation of each asbestos, tremolite. anthophyllite. actinolite job to accurately determine the airborne concentrations of asbestos, tremolite. anthophyllite. or actinolite to which employees may be exposed. (ii) The employer may demonstrate that employee exposures are below the action level by means of objective data demonstrating that the product or material containing asbestos, tremolite. anthophyllite. actinolite. or a combination of these minerals cannot release airborne fibers in concentrations exceeding the action level under those work conditions having the greatest potential for releasing asbestos, tremolite, anthophyllite. or actinohte. (iii) Where the employer has monitored each asbestos, tremolite. anthophyllite. or actinolite job. and the data were obtained during work operations conducted under workplace conditions closely resembling the processes, type of material control methods, work practices, and environmental conditions used and prevailing in the employer's current operations, the employer may rely on such earlier monitoring results to satisfy the requirements of paragraph (f)(2)(i) of this section. (3) Periodic monitoring within regulated areas. The employer shall conduct daily monitoring that is representative of the exposure of each employee who is assigned to work within a regulated area. Exception: When all employees within a regulated area are equipped with supplied-air respirators operated in the positivepressure mode, the employer may dispense with the daily monitoring required by this paragraph. (4) Termination ofmonitoring. If the periodic monitoring required by paragraph (f)(3) of this section reveals that employee exposures, as indicated by statistically reliable measurements, are below the action level, the employer may discontinue monitoring for those employees whose exposures are represented by such monitoring.

At the June 6 meeting you said it was decided negative pressure enclosures are not needed at Brownsville. I assume Mark Tapp concurred that it was not feasible to build enclosures. Jack Dermit, however, also indicated they were required. If there is any change in your position, please call me by September 7. Very truly yours. J. H. Smith Project Manager - Southern Region JHS/lkw/0246L Attachment cc: Belia Cortez'-''BfbWhsville, TXi Mark Tapp --League City, TX P. S. We have required negative pressure enclosures at Seadrift, Texas City and Ponce on recent dismantlements. BRG 0731
