This facility has a zero -flow discharge location. Facility failed to submit alternative analysis as required
from previous permit. Discharge point is actually 40 to 50 feet downstream from previous discharge
location but this will not affect limits. Facility has operational difficulties, and must install a continuous
flow measuring device. Effluent violations were noted in the past 18 months for residual chlorine. Fecal
violations were documented during the months of January, February, March, June and August through
November of 1994. Recommend NH3 limits of 2.0 mg/1 summer and 4.0 mg/1 winter, and 17.0 ug/1 for
residual chlorine (trout waters). Facility must be required to upgrade the existing facilities to meet tertiary
limits. Facility- has installed a new chlorination unit within the past eight months.

the facility has been compliant last 12 months. Facility will have problems meeting ammonia
limits. Recommend renewing with existing limits and changing ammonia limits from 1.0/1.8 mg/1
to 2.0/4.0 mg/1 to meet current definition of BAT for small discharges.
