The <br />Division also reviewed all subsequent revisions and stipulation responses to <br />ensure that all permit commitments and conditions were being followed. <br />Hydrologic monitoring data was reviewed in conjunction with the review of the <br />application to assess the adequacy of the monitoring plan and discussion of <br />hydrologic impacts.
