who discharge wastewater to HQW waters shall obtain a Summer 7Q10 flow and report this information to DEMLR. If the permittee cannot obtain a Summer 7Q10 flow for the receiving waters at the
discharge location, the permittee shall notify DEMLR, and the DEMLR Regional Office may require an annual flow report on a case -by -case basis.

7. If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit. Tier 2
Monthly sampling shall be done until 3 consecutive samples are below the benchmark or within the benchmark range.
3 TSS benchmark values are 100 mg/I, except when discharging to ORW, HQW, Trout, and PNA waters where they are 50 mg/I.
° For each sampled measurable storm event the total precipitation must be recorded using data from an on -site rain gauge.

If "NO FLOW" or "NO DISCHARGE, Enter "NO FLOW" or "NO DISCHARGE" for each outfall here. Please make sure to mark the sample period above.
a If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit, Tier 2
Monthly sampling shall be done until 3 consecutive samples are below the benchmark or within the benchmark range.
3 TSS benchmark values are 100 mg/l, except when discharging to ORW, HOW, Trout, and PNA waters where they are 50 mg/l.
"For each sampled measurable storm event the total precipitation must be recorded using data from an on -site rain gauge.
