1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.

numerical format. When results are below the applicable limits, they must be reported in the format. "<XX m /L". where XX is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L.
