1 Monthly sampling (instead of quarterly) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
3 For sampling periods with no discharge, you must still submit this discharge monitoring report with a checkmark here.
'The TSS benchmark value is 100 mg/L; except when discharging to ORW, HQW,Trout, and PNA waters in which case the benchmark is 50 mg/L.

QUALIFIERS
Project: Compost Central 1
Pace Project No.: 92465906
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.

All permits require qualitative monitoring to be performed during a"measurable storm event."
A"measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period,and the permittee obtains approval from the local DEMLR
Regional Office.
