Arndt , <br /> describing a biodegradable flocculant (Nalco 8103) . He <br /> has told me that this meets all effluent standards and is <br /> not in any way detrimental to aquatic life. <br /> We have calibrated the concrete box by the front gate and <br /> the 12t1 cmp that goes from the small pond to the large pond <br /> at No. 1 Mine and will maintain the dosage as closely as <br /> possible to 1 or 2 ppm. We will continue to work with Nalco <br /> to properly store, mix and flocculate our ponds . <br /> Please contact me if you have any questions. <br /> Sincerely, <br /> Environmental Coordinator <br /> DWBowman:ms <br /> Copies: <br /> J.
