4. For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge

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.
5. These parameters shall be monitored only if coal or coal ash is transported through the drainage
areas of these outfalls during the semi-annual monitoring period in Table 2.

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/l.
2. Values above the North Carolina water quality standard for mercury (12 ng/l) should be noted on the
DM R but do not trigger Tier responses. Concentrations infield blanks or method blanks associated
with the sample may he subtracted from the results for that sample, 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.
