The anticipated sampling dates are listed below in Table 3 -3. Unexpected circumstances or <br />adverse weather /site conditions may require that a sampling date be rescheduled. The Sampling <br />Plan will be updated with changes and DMG will be informed of the change in sampling schedule.. <br />Table 3 -2.
