Receiving Stream: UT to Mill Creek C-Swamp Index #: 30-6-5-(1) C33NW
From source to SR 1214 near Winfallr 7/1/73
WLA TBS 9/18/88
Recommended that Al be monitored for.
WLA had water classified as SC and thus gave them Turbidity at 25 NTU (should
be 50 NTU for C-Swamp)
Compliance data: No violations, but all values for the following have been the same every
month for the last two years: Q = 0.035, chloride = 72.0, C12 = 0 and iron = 120.0
Chloride is listed as 72.0 mg/1 on compliance sheet and as 72.0 ppm on DMR.
• Facility is monitoring for TSS monthy instead of bimonthly. *
• Facility is not monitoring for settleable solids. *
• No Turbidity monitoring; weekly U&D required. ORC will start this.
• The data for chloride (72 ppm) is where the operator is writing Chlorine on the
DMR's. He has a column for chloride and one for C12 Difference is?
Chlorine should be written as chloride
• Is alum flocculation used? No ko Ncet T A(ur„
11/3 Called the ORC, Russ Chappell, 426-8199 about the above bulleted items.
* Barry Adams and Kimberly Hall visited @ 3 wks ago and talked to him about these items.
ORC will start monitoring for turbidity, settleable solids and TSS bimonthly. He stated that
he will start using exact #'s on the DMR instead of rounding to the same ones every time.
CF Notes: No old SR
Letter dated 5/4/94 from Lyn Hardison to Russ Chappell told him that he was non-
compliant for not monitoring for everything on his permit.
(I will have compliance unit look into this.)
Drafted permit:
Made the following change - Turbidity limit changed from25NTU to 50 NTU.
