Dear Mr. Miller:
The Division of Water Quality received your request for changes in your monitoring
obligations at the subject facility on August 1, 2008. Based on our previous site visit on July 8,
2008 and our understanding of your representations of current site drainage conditions as
presented in your letter and site plan, we are granting the following revision to your monitoring
obligations under NCG080814.
Please maintain a copy of this letter on file at the facility.
You reported that Outfall at BMP- I and BMP-2 are similar. As a result of our
site investigation, the City of Charlotte may conduct the required analytical
sampling at MH8 as shown on your plan (monitoring point 002) to be a
representative sample for BMP-1. Please note that BMP-2 outfall must be
included in the twice -yearly qualitative monitoring event.
2. Continue the required analytical sampling from BMP-3 that collects drainage
from fleet fueling and washing area (monitoring point 001) as shown on your
plan.
3. Continue the required analytical sampling from BMP-4 that collects drainage
from bus maintenance staging area and outdoor materials storage area
(monitoring point 003) as shown on your plan.

RE: Representative Outfall Status Request
Charlotte Area Transit System Bus Maintenance Operations Facility (NCG080814)
3145 S. Tryon St., Charlotte
Dear Samar:
The Charlotte Area Transit System Bus Maintenance Operations Facility at 3145 S. Tryon St. in Charlotte
has one true stormwater outfall located at the northwest corner of the facility. All stormwater from the
facility discharges at that location; however, a significant amount of stormwater from offsite also
discharges from that same outfall.
In order to monitor stormwater that drains only from onsite locations, we determined that alternate permit
compliance monitoring locations needed to be identified. You and I met at the subject facility on July 8,
2008 to identify those monitoring locations. We identified four (4) such locations, which discharge
stormwater from materials handling areas and other areas of "industrial" activity (washing, fueling,
maintenance, bus parking, etc.). Two of the four monitoring locations we identified both drain areas
where only bus parking occurs. Because those two drainage areas are essentially identical, with no other
stormwater-impacting activities taking place, we are requesting representative outfall status. The
representative outfall location is indicated as Monitoring Point 002 (at MH8) on the attached Site Map.
The equivalent drainage area is located west of MH8.
Also, because the monitoring locations we identified do not discharge stormwater from the entire site, but
rather from smaller drainage areas, we are requesting representative outfall status for the other two
monitoring points/outfalls as well (see Monitoring Points 001 and 003 on the attached map). All
materials handling areas and other areas of "industrial" activity that occur at the facility drain to one of
the three monitoring points, so no significant areas will be missed with the proposed monitoring scheme.
Please contact me at [phone] if you have any questions or concerns.
Best Regards, fJ1
