<br /> 1 pH shall be determined at the time of sample collection for ammonia.
<br /> 2 Requires use of"clean technique"(EPA 163 1)for sampling,handling and analysis.
<br /> 3 Discharger must submit report outlining EPA test methods and detection limits by 15 February 2000 for
<br /> approval. Report all peaks identified by the EPA test methods
<br /> In conducting the receiving water sampling, a log shall be kept of the receiving water
<br /> conditions throughout the reach bounded by Stations R-1 through R-5. Attention shall be
<br /> given to the presence or absence of:
<br /> a. Floating or suspended matter e. Visible films, sheens or coatings
<br /> b. Discoloration f. Fungi, slimes, or objectionable growths
<br /> c. Bottom deposits g. Potential nuisance conditions
<br /> d. Aquatic life h. Flow
<br /> Notes on receiving water conditions shall be summarized in the monitoring report.
<br /> THREE SPECIES CHRONIC TOXICITY" MONITORING
<br /> Chronic toxicity monitoring shall be conducted to determine whether the effluent is contributing
<br /> toxicity to Dredger Cut. The testing shall be conducted as specified in EPA 600/4-91-002, or
<br /> later amendment. Chronic toxicity samples shall be collected at the discharge of the wastewater
<br /> treatment plant prior to its entering Dredger Cut. 24-hour composite samples shall be
<br /> representative of the volume and quality of the discharge. Time of collection samples shall be
<br /> recorded. The effluent tests must be conducted with concurrent reference toxicant tests. Monthly
