Table 6: pH Sampling and Limits for 303(d)-Listed Waters <br />Parameter identified in <br />Parameter <br />Analytical <br />Sampling <br />Numeric Effluent <br />303(d) listing <br />Sampled/Units <br />Method <br />Frequency <br />Limit <br />High pH <br />pH /Standard <br />pH meter <br />Weekly, if <br />In the range of 6.5 <br />Units <br />discharging <br />— 8.5 <br />2. At the Permittee's discretion, compliance with the limit shall be assessed at one of <br />the following locations: <br />a. Directly in the 303(d)-listed waterbody segment, inside the immediate area of <br />influence of the discharge; or <br />b. Alternatively, the Permittee may measure pH at the point where the discharge <br />leaves the construction site, rather than in the receiving water. <br />3. Discharges that exceed the numeric effluent limit for pH (outside the range of 6.5 — <br />8.5 su) constitute a violation of this permit. <br />4. Permittees whose discharges exceed the numeric effluent limit shall sample <br />discharges daily until the violation is corrected and comply with the non- <br />compliance notification requirements in Special Condition S5.F. <br />E. Sampling and Limits for Sites Discharging to Waters Covered by a TMDL or Another • <br />Pollution Control Plan <br />Discharges to a waterbody that is subject to a Total Maximum Daily Load <br />(TMDL) for turbidity, fine sediment, high pH, or phosphorus must be consistent <br />with the TMDL. Refer to http://NNrkvw.ecy.wa.gov/programs/wq/tmdl/ <br />TMDLsbvWria/TMDLbvWria.html for more information on TMDLs. <br />a. Where an applicable TMDL sets specific waste load allocations or requirements <br />for discharges covered by this permit, discharges must be consistent with any <br />specific waste load allocations or requirements established by the applicable <br />TMDL. <br />i. The Permittee must sample discharges weekly or as otherwise specified <br />by the TMDL to evaluate compliance with the specific waste load <br />allocations or requirements. <br />ii. Analytical methods used to meet the monitoring requirements must <br />conform to the latest revision of the Guidelines Establishing Test <br />Procedures for the Analysis of Pollutants contained in 40 CFR Part 136. <br />Turbidity and pH methods need not be accredited or registered unless <br />conducted at a laboratory which must otherwise be accredited or <br />registered. <br />b.
