Note: Results must be reported in numerical format. For example,do not report Below Detection Limit, BDL,<PQL, Non-detect, ND, 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
detection 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 text.
