'See General Permit text, Table 1, identifying protected receiving water classifications where the more protective T55 benchmark applies.
'Stormwater discharges into receiving waters classified as saltwater are subject to the second listed benchmark.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, SOL, <PQL, Non -detect, NO, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format. "<xx mg/L!' . where XX is the numerical value of the
jetection limit, reporting limit, quantitation limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark you must Implement Tier 1 Tier 2 or Tier 3 responses See General Permit
