Permits & Engineering Comments:
This is a permit renewal for a package wastewater treatment plant for an apartment complex. Files
and data indicate that the facility is generally in compliance with permitted limits with only a few
exceptions. The facility has had some operational difficulties (the chlorinator was leaking before),
but seems to be ok now. The application for renewal has not been submitted yet, but the permit requires
an alternatives analysis with the submittal. Also, the permittee was advised during the last
compliance inspection that they will need to submit the analysis. If no alternatives are available, the
ammonia limit will be set at 2.0 mg/1 summer and 4.0 mg/1 winter, and the permittee will be given the
choice between this limit and a chronic tox. test at 90%. The data suggest that the facility can meet
the ammonia limit on a regular basis. P&E recommends renewal with changes noted above.

Also, the permittee was advised during the last compliance inspection that they will need to

ammonia limit on a regular basis. P&E recommends renewal with changes noted above.
Update: The region withdrew the dechlorination requirement since the facility is not
required to meet a TRC limit. The flow sample box requirement has been withdrawn
because the box has been repaired. The facility will get ammonia limits of 2&4 to be
phased in in twelve months. Permit will be issued to Renae Ward the owner and not the
facility Sunset Apartments.

2. Special monitoring or limitations (including toxicity) requests: None.
3. Important SOC, JOC or Compliance Schedule dates: (Please indicate). None,
4. Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge options available.
No.
We have no alternative analysis evaluation (AAE) from this facility. I have called the permittee and
written letters, explaining the AAE.
5. Other Special Items: None
PART IV - EVALUATION AND RECOMMENDATIONS
A review of the self -monitoring results for 1996 indicates compliance with all current final effluent permit
limits. The proposed 5 mg/1 BOD5 and 2 mg/1 ammonia limits for discharges to zero flow streams will be
difficult for this plant to meet, based on the past self -monitoring data. The plant will possibly need to upgrade
to meet more stringent limits.
The following items need to be included in the permit:
1. A 12 month compliance schedule for the facility to meet the effluent limitations of the permit.
2. A statement requiring the permittee to obtain an authorization to construct to upgrade the existing
facilities to include dechlorination, flow sample box and to meet the effluent limitations of the
permit.
Recommendation is made to renew the permit in accordance with division policy.
