Rescission of NPDES Permits - Guilford County Schools _
Colfax Elementary School , NPDES Permit No. NC0038261 }'
Stokesdale Elementary School, NPDES Permit No. NC0038237
Rena Bullock School, NPDES Permit No. NCO038202
Summerfield School, NPDES Permit No. NCO038245
Guilford County
,& r n FvQ,u
Reference is made to the rescission of the subject NPDES Permits. Staff of our
Winston-Salem Regional Office have confirmed that none of the above schools currently
discharge wastewater and these Discharge Permits are no longer required. Therefore, these
NPDES Permits will be removed from our computer systems, effective immediately.
If in the future you wish to again discharge wastewater to the State's surface waters,
you must first apply for and receive new NPDES Permits. Discharging without a valid
NPDES Permit will subject the discharger to a civil penalty of up to $10,000 per day.
If it would be helpful to discuss this matter further, I would suggest that you contact
Steve Mauney, Water Quality Regional Supervisor, Winston-Salem Regional Office at
910n71-4600.
Sincerely,
A. Preston Howard, Jr., P.E.

----------------------------- COMMENTS -----------------------------------
Per standard Division procedure for discharges to streams with 7Q10=0
and 30Q2=0, recommend removal of discharge as soon as an alternate method
of waste disposal can be found. The instream monitoring requirement may
be dropped as soon as the facility agrees, in writing, to a schedule for
removal of discharge. Recommend instream monitoring of temperature, DO,
conductivity, and fecal coliform.
The downstream monitoring site has been changed to provide data more
representative of the discharges impact.
