SOURCE BRANCH
Silver Maples Mobile Estates
Dear Ms. Jackson:
I am in receipt of a copy of a Public Notice by the Environmental Management
Commission (Commission) that intends to renew the subject NPDES Permit (Permit). We are
aware that the Commission has a policy of eliminating discharges to the surface waters if at all
possible, and in this situation it will be very possible. For the record, we would like to object
to the renewal of this Permit because this discharge could be eliminated by connecting to the
existing Kings Grant Rocky River Interceptor. Therefore, we respectfully request that the
subject Permit not be renewed and that the Permit holder work with the City of Concord
(Concord) to make arrangements to connect this .discharge to the public system. Concord
would be the retail sewer provider for this system. Concord has expressed a willingness to
work in conjunction with the Permit holder so that this discharge could be eliminated.
As I am sure you are aware, the citizens of Cabarrus County object to the construction
of package plants because of the failure and historic poor operation of these facilities.
Therefore, we further request that any Permit for a non-governmental package plant have a
special condition that requires the plant be replaced by a connection to the public sewer system
when a line is within 1,000 feet.
If you have any questions, please give me a call at [phone].

The permittee, Silver Maples Mobile Estates, is applying for
renewal of the permit to discharge treated domestic wastewater..
A review of monitoring reports from 1/l/95 to 1/1/99 revealed 9
monthly flow violations . Also, the facility has been flooded by
the Rocky river 8 times in the past 5 years . The facility is
also experiencing Inflow/Infiltration that needs to be addressed.
Giving the urbanization along the Rocky River, a flood study .
should be conducted in order to determine flooding frequency at
the WWTP and whether the facility should remain at that location.
It should be noted that a sewer line for the Water and Sewer
Authority of Cabarrus County is available within 150 feet of this
facility.
It is recommended that the permit be issued for a period of
two years, during which a study regarding the flooding problem be
conducted. The study should also present -alternatives if
flooding is found to be a chronic problem at the plant .
We would suggest that the Mobile Home Park connect to the

nearby area-wide sewer.
