2 The discharge shall not cause the turbidity of the receiving water to exceed 50 NTU. If the turbidity exceeds these levels due to natural background conditions,
the discharge level cannot cause any increase in the turbidity in the receiving water.
3 See special condition A.(2). on the Supplement to Effluent Limitations and Monitoring Requirements Page.
4 The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
All samples collected should be of a representative discharge.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A.(2). Total Nitrogen Monitoring
The Permittee shall calculate annual total nitrogen mass loading as the sum of monthly loadings,
according to the following equations:
(L) Monthly Loading (lb) = Days x TN x Q, x 8.34
where:
Days = The number of discharge days in that month
TN = The average total nitrogen concentration (mg/1) of the composite samples
collected during the month
QW = The average daily waste flow (MGD) for the month
8.34 = Conversion factor, from (mg/l x MGD) to pounds
0' 1
The annual mass loading is the sum of the monthly loadings:
(2.) Annual Mass Loading Ob/yr)= T. (Monthly' Loadings) for the calendar year.
The Permittee shall report the total nitrogen concentration for each sample and the monthly mass
loading, in the appropriate monthly self -monitoring report; and the annual total nitrogen mass
loading. in the self -monitoring report for December of each year.

Summary
Facility has requested a permit renewal with no modifications to the existing facility
operations.
A review of the most recent compliance evaluation inspection report and all available DMR
data was performed. The most recent compliance inspection report was prepared on 12-
18-97. At that time, the facility appeared to be well maintained and the effluent was free
of solids. The DMR review revealed pH violations during the October 1996 reporting
period. No other violations were noted. One inconsistency was noted during the DMR
review. It is unclear where the facility is performing instream sampling. The facility
inconsistently reports the upstream and downstream location and sometimes does not
report a location at all. Region please comment on this issue.
