code description
CSC/R10PMT = Facility-supplied outfall locations in EPA Permit files trans-
ferred to 24k maps, then digitized by in-house contractor, 6/90
WDOE/1295 = Dump from Wash. Dept. of Ecology database, 12/95.
WDOE/0492 = Wash. Dept. of Ecology database, April, 1992.
WDOE PMT = From front page of WDOE NPDES permit, due to obvious errors in
WDOE/0492.
ESD/NOS10K = EPA dive team inspections, transferred to NOS chart at 1:10,000.
ESD/NOS10K = EPA dive team inspections, transferred to NOS chart at 1:80,000.
FAC = Facility-supplied by various textual/tabular means (without maps)
FAC/24KMAP = Facility-supplied data on 24K map.
FAC/63KMAP = ditto, on 63K map.
FAC100KMAP = ditto, on 100K map.
