               6-1. SAMPLING STRATEGIES. The sampling strategy developed should account for
               all possible spray painting activities within the booths.
                   a. The sampling is done during the painting of different vehicles and
               equipment, when the booths' filters are clean and dirty, when changes or
               modifications occur in or to the booths. and for each painter.

                   b.   The documentation should be revalidated biennially if the initial
               sampling results are 6#low one-half of the standard and Jtmi4nftUally if
               preatei,than one-half of the standard. .

                   c.   Additional monitoring is required whenever there has been a

               method for determining exposure limits. Area samples should be used to
               determine the effectiveness of control measures or locate problem areas.

                   b. The USAEHA TG No. 141 also--

                       (]) Contains procedures for submitting air samples.

                       (2) Identifies laboratories performing the analyses. When more than
               one analysis on a collected sample is desired, the laboratory performing the
