SW11-1 is monitored quarterly; however in previous years run-offevents contained <br />such high quantities of suspended solids that the sampler tubes were plugged and the <br />gaging device silted in. Due to this continued problem, grab samples and measurements <br />have been taken quarterly and during run-offevents at the mapped location of the <br />monitoring device since 6/95. <br />Constant servicing of these stations is necessary with no guarantee that the next run-off event will <br />be measured and a sample collected. This concern has been addressed in the most recent permit <br />review and in previous Annual Hydrology Reports. This information was also conveyed to Mr. <br />Jim Bernell (DMG Hydrologist) during an inspection of these locations on 5!20!97. Mr. Bernell <br />indicated at that time that he was questioning the necessity of monitoring these locations. <br />After discussing this situation further with Mr. Bernell on 7-07-97, and considering the potential <br />hydrological impacts reflected by the current surface water monitoring program, BME plans to <br />submit a Technical Revision to DMG requesting that the Surface Water Monitoring requirements <br />be eliminated from our permit. BME understands that Mr. Bernell is in agreement with this <br />decision. <br />BME requests that DMG consider this information and explanation when making the assessment <br />to NOV C-97-006. Also, as per our telephone conversation on 7-02-97, BME requests that the <br />30 day assessment deadline be waived. <br />Please contact me if you have any questions. <br />Sincerely, <br />Gordon H.
