2 For sampling periods with no discharge at any single outfall,you must still submit this discharge monitoring report with a checkmark here.

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
