Special Condition(s):
Permits & Engineering Comments:
This is a permit renewal for an extended aeration treatment system, with additional limits for
increased flow. Files indicate that the facility has been in violation of permitted limits, especially
TSS, in 1996. The facility is experiencing problems with treatment during peak flow periods, and it was
suggested to the permittee that flow equalization be investigated and a flow recorder be installed. The
ammonia limit at 0.12 MGD was previously permitted as a year-round limit. No basis for a year-round
limit was outlined in the wla. Therefore, per current SOP for ammonia/tox. limits, the ammonia limit
has been set for the summer, and monitoring only is required for the winter. P&E recommends renewal of
permit with changes noted above. Region: Can we anticipate% facility going to class III at the
