LeC:lerc , <br /> TI-e purpose of t.hi _• 1 e t t e r i s to e x p 1 ai n r,ur appl i cat.i on for <br /> waste discharge at. the Micke Grove Golf Course in the County of <br /> San Joaquin . <br /> In general , what we propose to do is drain our rnaintenance yard <br /> wash area into a grease trap , and then drain the water off into <br /> one of our sealed ponds . (please see attached drawings ) <br /> The purpose of the wash area is to clean the maintenance <br /> machines after they have been out on the course . This is not <br /> an area where we will be cleaning off the engines or changing <br /> the oiI in the rnachines . The wash area is only to clean the grass <br /> off the rnachines, after they have been mowing the golf course . <br /> We. have eight ponds on the golf course and all have been <br /> chernicalIy sealed with the seepage inhibitor ESS- 13 , as well as <br /> the Soil Stabilizer E- 13 . Please see the attached detail = on the <br /> application of t.hese sealants and their permeability . The <br /> permeability of this seal is 1x10 -7 c . p . s . or less . I <br /> understand it. is your policy to discharge all waste into an above <br /> ground tank , or into a sealed pond . We feel we meet the <br /> requi rernent. of di 5char9i ng i n t o a sealed pond . <br /> If there are any further questions , please feel free to call me <br /> at any time , 209-474 -3750 .
