SUBJECT:
NPDES Permit Modification
The Hideways
NPDES Permit No. NCO057401
Mecklenburg County
This Office is in receipt of an NPDES Permit application from Mr. Charles
Gallant concerning a modification to the Permit. Mr. Gallant is requesting
an increase in flow from the originally permitted flow of 0.002MGD to 0.200MGD.
This increase in flow will come from the proposed construction of approximately
400 condominiums on nearby property. The existing WWTP serving the Hideways
will be abandoned once the proposed project has begun. Mr. Gallant indicates
that the 0.200MGD WWTP will be constructed in stages until maximum flow has
been attained. A rotor disk type WWTP, similar to the one currently in opera-
tion at the Hideways, is planned for the project. This facility could be
expected to meet secondary limitations if the revised WLA indicates such
would continue to be applicable.
This Office has evaluated this proposal and recommends approval provided
the DHR concurs. It should be noted that a second and third discharge is
proposed for this section of the lake just above the point where the existing
Hideways WWTP discharges. These two (2) proposed discharges (Summitview -
NC0067202 and Langston Drive - NCO064441) will, if approved, generate an
additional 0.400MGD into this section of the lake. Because of the nature
of the development proposed for this area, the possible creation of nuisance
conditions and the volume of WW discharged, it is recommended that the discharge
line for the proposed Hideways WWTP be piped an additional 150 feet into the
main river channel. This recommendation will also be made for Summitview and
Langston Drive prior to issuance of an A to C. Locations of these proposed
discharges can be found on the attached map.
If you have any questions regarding this matter, please advise.
