amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Charlotte -Mecklenburg Utility Department
Mecklenburg County
FOR THE
construction and operation of a bulk reclaimed water distribution program and all associated facilities at
the Franklin Water Treatment Plant (NPDES Permit No. NC0084549). Bulk reclaimed water, following
treatment and testing according to the water reclamation facility's existing NPDES permit and the
conditions provided herein, may be manually distributed from a three-inch hose connected to a quick -
connect coupling and controlled by a lockable control panel at a newly constructed truck filling station.
All reclaimed water distributed must be measured and recorded. Bulk reclaimed water may only be
distributed to approved trucks and drivers for the following uses: sewer line flushing, dust control for
street sweeping, irrigation of landscapes not intended for human consumption, vehicle washing at
construction sites (not including vehicle underbody), and construction uses such as soil compaction, dust
control, and asphalt reclamation. The bulk reclaimed water distribution program shall be operated such
that no discharge of wastes to surface waters occurs, pursuant to the application received August 21, 2002
and in conformity with the project plans, specifications, and other supporting data subsequently filed and
approved by the Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until April 30, 2012, shall void Permit No.
WQ0021734 issued October, 23, 2002, and shall be subject to the following specified conditions and
limitations:
1. SCHEDULES [please review the entire permit for reporting, monitoring, and other on -going activities]
