CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is -? _% (defined as treatment two in the North Carolina procedure
document). ;The permit holder shall perform guarterly monitoring using this procedure to establish
compliance with the permit condition. The. first test will be performed after thirty days from
issuance of this permit during the months of J4Ng A?9, J t.cL�, D CT Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below
all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT -I (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in -association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

COMMENTS OF WASTELOAD ALLOCATION
CITY OF MEBANE
NC 0021474
A review of the self -monitoring data produced the following
observations:
(1) Copper has averaged 23.19 ug/l.
(2) Zinc has averaged 128.71 ug/l.
Mebane has an IWC of 99%. Therefore, the copper value
(23.19) x IWC produces 22.95 ug/l. This exceeds the 7 ug/1
action level. Zinc (128.71) x IWC is equal to 127.4 ug/l. This
exceeds the zinc action level of 50.0 ug/l. These corrected
values reflect "no upstream" zinc or copper and 7Q10 conditions.
The WSRO recommends that copper and zinc have 7 ug/1 and 50
ug/1 permit limits respectfully because of their toxicity
history. Instream monitoring of copper and zinc is requested.
The WSRO recommends that the total phosphorus limit be on a
monthly and not on a quarterly basis.

MEMORANDUM
TO: Don Safrit
Trevor Clements
FROM: Steve W. Tedder
SUBJECT: City of Mebane Expansion Request
Upon consideration of the facts surrounding the nutrient controls
necessary for facility expansion, the WLA and permit should reflect limits for
phosphorus as 2.0 mg/I.
In addition, a condition should be added to the permit that will require
removal of the dam on Lake Latham prior to facility operation above the
currently permitted flows.
Please proceed with these modifications immediately.

Technical Support Branch
SUBJECT: Proposed expansion of City of Mebane WWTP
NPDES Permit No. NC0021474.
Alamance County
Technical Support has been working with the Winston-Salem
Regional Office to develop an acceptable scenario under which Mebane
would be allowed to expand their discharge. Initial concerns
regarding Mebane's ability to adequately operate and maintain a
municipal treatment plant and pretreatment program have been
resolved. However, both the region and Technical Support agree that
the expansion should not proceed with the outfall located at the
City's existing discharge point above Latham Lake. The current
receiving stream, Moadam Creek, has a 7Q10 flow of zero. During dry
periods the discharge provides the only inflow to the lake.
A recent intensive survey conducted in June indicated severe
problems in the lake. An algal mat covered the entire lake leaving
no open water areas visible. Lake samples indicated the mat was most
likely formed of blue-green algae, a nuisance species. The DO
concentrations at the surface of the lake in mid -afternoon were only
3.4 mg/l. The highest DOs are expected in the afternoon due to
photosynthesis. Even with the best available technology, we do not
think a problem of this magnitude can be remediated. Therefore, an
alternative discharge location must be found.
One option may be Back Creek (above SR 1936; below confluence
with Moadams Creek). Back Creek has a positive flow (7Q10=0.5 cfs)
but limited assimilative capacity. The limits for this option
would be:
summer winter
BODS 5 10 mg/1
NH3-N 1 1.8 mg/1
DO 6 6 mg/1
Fecal Coliform 200 200/100ml
pH 6-9 6-9 su
Total Phosphorous 2 2 mg/1
Chlorine 0.028 0.028 mg/1
Dechlorination will be required.

Effluent monitoring for copper, zinc, and silver will also be
required. Quarterly chronic testing at 89% will be required.
Other options may need to be explored. Your assistance in
expediting this process will be greatly appreciated. Please let me
know if you have further questions regarding this matter.

SUBJECT: Proposed expansion of City of Mebane WWTP
NPDES Permit No. NC0021474.
Alamance County
Upon evaluation of the City of Mebane's proposed expansion to
2.5 MGD, it has been determined not to permit expansion at the
existing discharge site. Moadams Creek is an effluent dominated
stream with a 7Q10 of zero and positive 30Q2. The Winston-Salem
regional office opposes Mebane's expansion to Moadams Creek.
Technical Support recommends relocation of the discharge site to Back
Creek (above SR 1936; below confluence with Moadams Creek) to remove
the source of severe degradtion to Latham Lake located 1 mile
downstream of the discharge. Back Creek has a positive flow
(7Q10=0.5 cfs) but limited assimilative capacity. It is recommended
that the facility meet tertiary limits at the Back Creek site.
summer winter
BODS 5 10 mg/1
NH3-N 1 1.8 mg/1
DO 6 6 mg/ 1
Chemical specific limits will be revised for the new site. The
instream waste concentration will be 89%. Dechlorination will be
required.
Please let me know if you have further questions regarding this
matter.

WATER Q WrY.ITY
SECTION
Reference is made to a memorandum to you dated
June 5,1990 concerning problems associated with the subject
facility. This memo pointed out problems that have occurred
at the Town of Mebane's existing WWTP. These problems
consisted of violations of effluent limitations, violations
of the pretreatment program, and violations of their land
application of sludge permit.
Subsequent investigations and meetings with the Town
Manager and Engineer has found that these violations appear
to have been attributed to the ORC during the time the
violations occurred. This ORC is no longer an employee of
the Town. The Town has or is taking the steps that the WSRO
staff believe are necessary to correct the above stated
violations. Therefore, the WSRO withdraws our previous
objections to reissuance of the NPDES Permit that was based
on these violations.
However, the WSRO does not withdraw our objections to
issuance of a NPDES Permit that would allow the Town to
expand their WWTP from 1.2 MGD to 2.4 MGD. This WWTP
discharges into Moadams Creek in the Gripe Fear River Basin.

This is a class C-NSW stream with a U.S.G.S. estimated low
flow of 0.0 cf s at 7Q10 and 0.07 cf s at 30Q2.
As can be seen this stream is currently dominated by
wastewater. Having dealt with several effluent dominated
streams in the Winston-Salem Region it is our opinion this
type stream is not environmentally sound nor a good way to
manage the States resources. It is felt that if this
expansion is allowed that irreversible harm will be caused
to biota and wildlife downstream of the increased discharge.
It should be noted the Town does have several options
mow to increase their wastewater flow. They could extend
the outfall line to a larger stream, build an additional
WWTP to discharge to another larger stream, seek an
alternative to a discharge, or maybe construct an outfall
line to the City of Burlington WWTP. These options have been
discussed with the Town Manager and Engineer.
If you should have any questions or wish to discuss
this matter, please advise,

SUBJECT: Priority Pollnalysis
City of Mebane
NPDES Permit No. NC0021474

Enclosed is a copy of the subject report Form A. It
appears that the 10 highest peaks were not identified. Is
this permissible?
The composite sample ran from January 22nd. to the 23rd.
Notice the concentration detected for cadmium and mercury.
The City ran a composite sample for self -monitoring on
January 24th and 25th. Cadmium was reported at 0.003 mg/l
and mercury at 0.0011 mg/l. The concentrations detected for
the priority pollutants was <1.0 ug/l and <0.20 ug/1 for
cadmium and mercury respectively. We have taken enforcement
against the city of cadmium and mercury permit violations.
R & A Labs ran both test. Do you feel comfortable with the
priority pollutants analysis or should another one be
required?

SUBJECT: City of Mebane WWTP Expansion
NPDES Permit No. NCO021474
Alamance County
The City of Mebane currently operates a 1.2 MGD
wastewater treatment plant. They have requested to expand
to 2.5 MGD. The City, through Alley, Williams, Carmen &
King, Inc., have requested monies from the State Revolving
Fund to finance the expansion. The Construction Grants
Section has allocated $2,600,000 for this expansion.
The WSRO has recommended that the City of Mebane be
subject to enforcement action. Specifically, the City of
Mebane violated G.S. 143-215.1(a) (6) on six occasions
between August 1989, and January 1990, when the City
permitted waste to be discharged into Moadams Creek in
violation of permit limits for cadmium. Mercury violations
occurred on three occasions between October 1989, and
January 1990. In addition, pH was violated in August 1989.
The City has not undertaken corrective measures for the
effluent permit violations.
The City has not taken adequate enforcement actions for
pre-treatment facilities in reportable non-compliance. Mr.
Everett signed a Proposed Assessment and Notice of
Continuing Penalties (NCP #90-01) against the City on May 1,
1990.

- 2 -
The City has been informed of a pre-treatment facility
falsifying their data. The City has not investigated this
matter. Cathy Tyndall has found the pretreatment program
inadequate.
The City has not demonstrated that the existingfper it
limits can be met. The WSRO does not feel that
low
should increase for a facility that is non -compliant. The
upgrade will be for new aeration equipment, a new clarifier,
final filters, a digester, chemical storage and feeding
equipment for phosphorus removal and chlorination/
dechlorination.
The City requested by letter dated May 10, 1990, that
their NPDES Permit be modified to reflect additional
flow.

reservations about a facility dischargingdirectly above an
impoundment like that found on Moadams Creek.
The City has not been properly implementing their
sludge permit for land application. The
WSRO
recommended enforcement action for the sludge permit
violations.
The City has reported a large I&I problw in mIn fact,

is enclosed.
The City of Mebane has averaged 0.6631 MGD over the
last 10 months. This is just over one-half of design
flow.
If the City addressed their I&Iproblem and hired a would meet existing permit

The WSRO recommends that the grant be reallocated to
another facility and the request for expansion be denied.
