For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge Form SWU-247, last revised 21212012 Page 1 of 3 is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading may be substituted for an on -site reading, S. These parameters shall be monitored only if coal or coal ash is transported through the drainage f areas of these outfalls during the semi-annual monitoring period in Table 2. Footnotes: Permit # NCS000580 Part 1I Page 9 of 15 1. Hardness- dependent. Benchmark based on translation of dissolved value into total recoverable with an assumed hardness of 25 mg/1 and a total suspended solids (TSS) concentration of 10 mg/I. 2. Values above the North Carolina water quality standard for mercury (12 ng/1) should be noted on the DM R but do not trigger Tier responses. Concentrations infield blanks or method blanks associated with the sample may be subtracted from the results for thatsample, as long as all documentation of the adjustment is provided with the DMR. 3. If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented to demonstrate background concentrations were below the benchmark pH range of 6- 9.
