°See General Permit text, Table 1, identifying protected receiving water classifications where the more protective TSS benchmark applies.

- umerical 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
nection limit, reporting limit, quantitation limit, etc. in mg/L.
Note: If you re ort a sample value in excess gof the benchmark ou must implement Tier I Tier Z or Tier 3 resl2onses. See General Permit.
