'Sto'rnwater discharges into receiving waters Classified as soltwitterare subject to the second listed benchmark.
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 me/L", where XX is the numerical value of the
ietection limit. reporting limit, quantitation 'J nit, etc. iu mg/L.
