Compliance is defered for two (2) years (see compliance schedule). During this period, the facility is required to
monitor and report the monthly average and daily maximum concentrations.
Monitoring begins the effective date of the permit.
Monitoring is required for one (1) year beginning 36 months from the effective date of the permit.
If chlorination/dechlorination is utilized. If an UV system is utilized, the City of Altus may request that the permit be
modified to remove the limit for Total Residual Chlorine.
No measurable is defined as less than 0.1 mg/l. If no chlorine is used for an entire reporting period, the permittee shall
report a value of “zero” for the daily maximum and enter “No chlorine used this reporting period” in the comments
section on the DMR for that reporting period in lieu of the indicated testing. For any week in which chlorine is used,
the indicated testing shall be done until the chlorine is no longer in use and at least one subsequent test verifies that the
effluent meets the total residual chlorine limit (see also footnote d).

Permit Part I- Page 3
Other Year round Requirements:
There shall be no discharge of floating solids or visible foam in other than trace amounts.
There shall be no discharge of any visible sheen of oil or globules of oil or grease.
All monitoring and reporting requirements shall also be in compliance with Part III of this permit.
Samples taken for compliance with permit limits and monitoring requirements specified above shall be taken
at the discharge from the contact basin located in the NW¼, SE¼, SE¼, Section 23, Township 2N, Range 20
WIM, Jackson County, Oklahoma.
B. Whole Effluent Toxicity Reporting and Monitoring Requirements
During the period beginning with the effective date and lasting through the expiration date of the permit, the
permittee is authorized to discharge from Outfall TX1 (functionally identical to Outfall 001). Such discharge
shall be limited and monitored by the permittee as specified below.
The permittee is encouraged to perform required biomonitoring activities as early in the reporting period as is
practical so as to ensure sufficient time remains in the reporting period should retests/repeat tests be
necessary.
All laboratory analyses for the parameters specified in the biomonitoring section must be performed by a
laboratory certified by the Oklahoma Department of Environmental Quality for those parameters.

Quarterly reporting periods commence with the effective date of the permit. A valid WET test shall be reported for
each species for each reporting period. Results of retests conducted pursuant to prior test failure shall not be
submitted on DMRs in lieu of routine test results.
All chronic WET testing shall use the dilution series specified in Part II, Section E, Item 1.

Whole Effluent Toxicity Concurrent Testing Provision:
Concurrent analysis of total ammonia and pH is required for each individual effluent sample collected for
acute WET testing or retesting of the Fathead minnow species. Concurrent analyses of TDS and constituent
ion species are required for each individual effluent sample collected for Ceriodaphnia dubia WET testing or
retesting. For purposes of concurrent testing requirements, TDS constituent ion species are: K + (potassium),
Na+ (sodium), Ca+2 (calcium), Mg+2 (magnesium), Cl (chloride), HCO3 (bicarbonate) and SO42 (sulfate).
Reporting of concurrent testing results shall be in accordance with the following requirements.

required concurrent analyses in addition to the WET testing itself.

Two sets of samples for concurrent analyses are required for ammonia and pH:
Concurrent ammonia analyses must be performed on composite samples that are properly preserved and delivered
directly to a state certified analytical laboratory. These results shall be included in the results for Outfall 001.
Samples sent directly to a WET testing laboratory shall not undergo any preservation other than refrigeration to no
greater than 6º C but not frozen prior to arrival and processing at the WET testing laboratory.
A second concurrent analysis is required for the sample that is sent to the WET testing laboratory and for the table
above. Just prior to first use of each composite sample for WET testing purposes, the biomonitoring laboratory shall
take an adequately-sized portion of each composite sample, acidify it in accordance with preservation requirements
in 40 CFR 136, and have it analyzed for total ammonia at a state certified laboratory. The pH measurement required
for the above table must be taken just prior to the acidification step. These pH and ammonia readings should NOT
be included in the results for Outfall 001.
c
Report only those effluent samples collected for WET testing of the Dapnia species
Concurrent analyses required for TDS:
The concurrent TDS sample is taken at the beginning of the biomonitoring test. Only one sample is necessary and it
must be sent directly to a laboratory certified by the state for the TDS analyses. The analyses must include the
constituents listed for TDS above the concurrent table.
It must be a composite sample that is properly preserved and refrigerated to no more than 6º C. This result may be
included in the results for Outfall 001, if required.

Permit Part I- Page 6
Sampling Location for Biomonitoring Requirements:
Samples taken in compliance with the monitoring requirements specified above for Outfall TX1 shall be
taken at the same location as for Outfall 001 (see Page 1 for latitude/longitude and legal location).
C. Sanitary Sewer Overflows
Any bypass in the collection system [sanitary sewer overflow (SSO)] shall be reported in accordance with
Part III.B.6. of this permit.
D. Compliance Schedule
The permittee shall achieve compliance with the specified effluent fecal coliform limitations in accordance
with the following schedule. During the period from the effective date of the permit through the date the
facility is required to achieve full compliance with the effluent limitation, the facility is required to monitor
and report the monthly average and daily maximum concentrations.
