It must be recognized, however, that this <br />does and can occur as a result of precipitation events only, based upon past <br />observations, and not wholly due to our spray application activities. We have been <br />concerned with this to the extent of avoiding surficial ponding as much as possible and <br />preventing overland flow of water in relation to our spraying activities. Care will <br />continue to be exercised when we are conducting evaporative spraying activities to <br />assure that water is not released to Windy Gulch. <br />Please be advised that we discontinued spray application water management activities on <br />11/15/97 with adit seepage being reported to the infiltration trench; this will continue <br />until next Spring or at such a time as adit flows cease. Next Spring we will resume <br />evaporative spray applications as ground and weather conditions allow. <br />We are continuing to work on the caved section in the 9360 workings along with re- <br />construction of timber support as we progress; most of the summarized details of our <br />recent activities were forwarded to you recently in our November monthly report. <br />If you have any questions, or require further information, please contact me in the San <br />Francisco office. <br />Very Truly Yours, <br />i~~l~~~ <br />Cc: B.
