1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmarkdante for the ring report sah a ame art mark ter at tee same outfall.
2 For sampling periods with no discharge at any single outfall,you must still submit this discharge mon
3The 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.
4 See General Permit text,Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example,do not resort Below Detection Limit,
BDL, <PQL, Non-detect, ND,or other similar non-
numerical format, When results are below the applicable limits,the must resorted in le armat "<XX m_ L" where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L. Conversely,where fecal coliform results exceed the dilution upper limit, report the result as ">XX".
Note: If you report a sample value in excess of the benchmark,you must implement Tier 1,
TiOr Z or Tier 3 responses. See General Permit text.
Part B: Vehicle Maintenance Area Monitoring Results: only for facilities averaging . 55 gal of new oil per month.
