2.Outfall TX1 (Whole Efflluent Toxicity)
During the period beginning the effective date and lasting through the expiration date, the permittee is authorized to discharge from Outfall TX1, which is functionally identical to Outfall 001. Such discharge shall be 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 biomonitoring and concurrent analysis parameters specified in this permit must be performed by a laboratory certified by the Oklahoma Department of Environmental Quality for those parameters. Samples sent directly to the WET testing laboratory shall not undergo any preservation other than refrigeration to not more than 4 ºC prior to arrival and processing at the WET testing laboratory.

eApplies to either or both test species according to results of test failure triggering monthly retests.
fMonthly retesting required only if routine test for reporting period (for either species) fails. Only the two retest parameters are to be filled in on retest DMRs. Results of the original retest-triggering test (the portion of the above table labeled “routine testing”) are not to be filled in for retests. The date to be annotated in the lower right hand corner of retest DMRs is the date retest results are submitted, not the date of the original retest-triggering test.
D. pulex whole effluent toxicity reporting and monitoring requirements apply beginning ______, and the first reporting period is ______to ______.
P. promelas (Fathead minnow) whole effluent toxicity reporting and monitoring requirements apply beginning ______, and the first reporting period is ______to ______.
WET testing summary reports: Reports of all acute WET testing initiated, regardless of whether such tests are carried to completion, shall follow the requirements of Part II, Section F, Item 4.
(2)Concurrent Testing Provision for Acute WET Testing
Concurrent analyses of total ammonia and pH are 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 Daphnia pulex WET testing or retesting. TDS constituent ion species are: K+ (potassium), Na+ (sodium), Ca+2 (calcium), Mg+2 (magnesium), Cl (chloride), HCO3 (bicarbonate) and SO42 (sulfate). Samples collected for acute WET testing purposes, including static renewals, shall be of sufficient volume to allow for the required concurrent analyses in addition to the WET testing itself. Samples sent directly to a state certified analytical laboratory for concurrent testing purposes must be composite samples that are properly preserved, and the results of these samples may be included in the monitoring requirements for Outfall 001. Reporting of concurrent testing results shall be in accordance with the following requirements. Results shall also be submitted in or concurrently with each full WET test report.

Two sets of samples for concurrent analyses are required for ammonia and pH, including those taken for static renewals. The first concurrent analysis is performed on a sample preserved in accordance with 40 CFR 136 (acidification is performed after pH measurement on-site) and delivered directly to a state certified analytical laboratory for total ammonia analysis. These results shall be reported as required in the above table for Outfall TX1. The second concurrent analysis is required on the composite samples that are delivered to the WET testing laboratory. Just prior to the first use of each composite sample for WET testing purposes, the biomonitoring laboratory shall take an adequately-sized portion of each composite sample, measure the pH, acidify it in accordance with the preservation requirements in 40 CFR 136, and have it analyzed for total ammonia at a state certified laboratory. The pH and ammonia results for the latter sample are for documentation only and shall not be used to fulfill the concurrent testing requirements in the above table. The results from both sets of samples for concurrent testing (that acidified on site and delivered directly to an analytical laboratory as well as the one acidified and analyzed after receipt by the WET testing laboratory) shall be recorded in the full WET test report.
bSee provision for WET testing monitoring frequency reduction after the first year (Part II, Section F, Item 5).
cThe pH measurement must be taken just prior to the acidification step.
