2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
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.
° See General Permit text, Table 1, 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 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 ml~/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 ">W

Please verify whether Qualitative Monitoring must be, performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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 DWQ Regional Office.

To Whom it May Concern:
The enclosed DMRs (original and one copy) are being submitted for stormwater outfall
monitoring samples collected on February 9, 2015 as part of a permit monitoring requirement
at the City of Charlotte- Central Yard, Certificate of Coverage number NCG080822. The
reason for the late submittal is that data was just recently discovered by me during a review
of the site's Stormwater Pollution Prevention Plan. Mecklenburg County Stormwater staff
collect the samples on our behalf under a contract. They collected the samples and prepared
the DMR, but failed to communicate that the samples had been collected and the DMR was
ready to go. This is the first time this has happened since we've had permit coverage for this
site, and we've set up a communication system going forward to ensure that it does not
happen again.
Thank you,
