Brief of WLA Analysis
1977: discharge approx. 1/2 mile below Mnt Lake Dam. Limits of 23 BOD5, 19 NH3-N, 5 dissolved oxygen, 1,000 fecal, 30 TSS,
6 - 9 pH. A few months later, (1978) those limits were documented to be 30 BOD5, 17 NH3-N, 5 dissolved oxygen, etc.
1983: pipe 001 - o in Tsivoglou equation and remodeling yeilded Secondary limits w/ a 1.0 dissolved oxygen.
pipe 002 - boiler blowdown, temperature and pH limits
pipe 003 - cooling water, temperature and pH limits
pipe 004 - oil storage facility runoff, oil & grease limits
pipe 005 - filter backwash, settleable solids, TSS, pH, and turbidity limits
1988: remodeled, (per Region request) and Secondary limits w/ a 5.0 dissolved oxygen were recommended. Later that year, the
Region requested the addition of Chronic Toxicity Testing; initially monitoring, then after 6 months a limit of 51 %.
1990: facility tied all outfalls into one pipe, (therefore 001 expanded from 0.100 mgd to 0.200 mgd). Remodeled w/ much longer
segment due to high CBOD's and NBOD's, (dissolved oxygen was not predicted to drop below 5.30 mg/I). Facility had been
experiencing high NH3-N levels in their effluent and did not have a good toxicity test record. It was assumed that ammonia
was the dominating reason for the toxicity failures. Facility had primary and secondary Imhoff tanks, (basically an above
ground septic tank) and proposed expansion was for extended aeration package plant. Tedder over -rode the recommended
NH3-N limits, (1.4 / 4.9 mg/I) in favor of monthly Toxicity Testing. Instream monitoring was increased; wkly over summer and
monthly over winter. A 25.0 µg/I residual chlorine limit was also recommended.
DMR's
two solids and one fecal violation over past year.
facility was under SOC in 1992
Toxicity Testing record very poor
Not taking dissolved oxygen measurments w/ temperatures consistently for instream monitoring. Summer months indicates
supersaturation.
Honeycutt (Operator Certification and Training) visited the facility in 1993
ESB sent letter adressing toxicity problems in 1992
ORC is including hand-written notes as to status of upgrades and toxicity problems, (1994 notes attached)
