Dept. of EHNI AUG 1 1992 ReclEor a C.i tficcV 287 82.2 163 379 5.35 Wasteload Allocation Summary (approach taken, correspondence with region, EPA, etc.) The facility is currently discharging to Heatherly Creek, which yields an IWC of 94%. The facility cannot meet its toxicity limit and may relocate to the Ararat River which would yield an IWC of 5% with a flow of 3 MGD. Pilot Mountain is under a JOC due to its failing innovative treatment technology. Federal funds will enable the facility to improve their treatment system and, hopefully, meet their final limits. Previous speculative WLA was performed for a possible discharge to Tom's Creek. Because the Town is seeking long term solutions, the Ararat River may be their best alternative at a flow of 3 MGD. Mt. Airy is appx. 13 miles upstream. The facility should be aware that limits may become more stringent upon basin -wide renewal.
