Dear Mr. Wilkins:
R. Paul Wilms
Director
The Technical Support Unit of the Division of Environmental Management
has partially completed the evaluation of Gastonia's discharge alternatives
for the 201 Amendment. Preliminary stream impact analyses have been fin-
ished for the proposed State Line/Crowders Creek WWTP and both of Gastonia's
facilities on Long Creek and Catawba Creek. The fourth site requested,
Kings Mountain's facility, will require substantially more time in obtaining
verification of stream flows, reviewing ambient water quality data and
developing an updated Level B model for McGill Creek. If the Kings Mountain
site is still of a high priority after reviewing the results of the other
alternatives, please notify us, so that we may allocate additional time to
our staff to continue work on this project.
It's important to remember that these effluent limits are preliminary
and are not final wasteload allocations. Final wasteload allocations will
be determined after the City of Gastonia submits an official NPDES permit
application.
A brief capsule of recommended limits and pertinent comments for the
State Line WWTP, Gastonia - Long Creek and Catawba Creek WWTP's follows:
1) State Line and Crowders Creek WWTP
The South Carolina Department of Health and Environmental Control was
instrumental in the development of these limits. A QUAL2E microcomputer
model was used by this agency for an analysis of Crowders Creek and these
limits were recommended to protect water quality:

South Carolina's concern over the eutrophic condition of the Crowders
Creek Cove of Lake Wylie is the basis for the phosphorus limit. The cove's
ranking as the fourth most eutrophic lake in South Carolina supports action
for some control of phosphorus inputs.

This facility is also of concern regarding loading to the cove area of
the lake. The Division has tentatively scheduled field work for this summer
to investigate eutrophic conditions. Nutrient removal may be recommended as
a future requirement for the Catawba Creek plant.

Further evaluation of ambient water quality data will be needed to
determine possible impacts to Long Creek and South Fork Catawba River, from
the Long Creek WWTP and Town of Dallas WWTP.

RE: Proposed Crowders' Creek WWTP
Plant Effluent Limitations
Dear Mr. Wilkins:
R. Paul Wilms
Director
The Division of Environmental Management has received your letter dated
2/23/88 concerning the request for effluent limits at the subject facility.
Your 1/12/88 requests for limitations has already received priority and work
is proceeding in a timely fashion.
The submitted information requested allocations at four sites. This
alone requires additional work by the staff and the United States Geological
Survey to establish limitations. In addition, one site is at the North
Carolina/South Carolina border which necessitates coordination with other
state agencies.
We anticipate that our work will be completed by March 31, 1988. if
there are additional questions, please contact Charles Wakild or Steve
Tedder at [phone].
Sincerely,

Proposed Wastewater Treatment
Plant Effluent Parameters
Dear Mr. Wilms:
The City of Gastonia and our Consulting Engineers (J.N. Pease Associates) are
working quite closely with your staff on a "fast track" program leading to what
is expected to be a new, large regional wastewater treatment facility. Due to
EPA funding requirements, the City's time frame for project planning completion
is most limited.
Of most vital importance at this time is our receipt of wastewater treatment
facility effluent parameters which we have requested of NCDEM. Our requests
for such parameters, made to NCDEM through our Consultants on January 12, 1988,
have not been established as yet; and we are becoming quite concerned over
possible delays to our planning efforts.
Any assistance you can provide the City in this matter would be greatly
appreciated. Should your staff need any data not already in their file, please
let me know immediately and it will be supplied.
Sincerely,
Samuel L. Wilkins, P.E.
