ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Fathead Minnow 24 hr - No Significant Mortality
The pernuttee shall conduct acute toxicity tests on a auarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute
Toxicity In A Single Effluent Concentration". The monitoring shall be performed as a Fathead
Minnow TWjWhales p%mdu) 24 hour static test, using effluent collected as a 24 hour
composite. The effluent concentration at which there may be no time significant acute mortality
is 90% (defined as treatment two in the North Carolina procedure document). Effluent samples for
self -monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The fast test will be ormed after thirty days from issuance of this permit during the
months of 14"
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
appropriate parameter code. Additionally, DEM Form AT-2 (original) is to be sent to the following
address:
Attention: Technical Services 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 doselresponse 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 test data from either these monitoring requirements 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 a failure of permit condition.

Marshall 201 Facilities Plan
Project No. C370512-01
We are in receipt of an amendment on the subject plan.
Based on this submittal it appears that the Town of Marshall
plans to expand their WWTP to 400,000 gpd. This flow is
comprised of 180,000 gpd domestic, 150,000 commercial,
50,000 gpd I/I and 20,000 gpd non specified. The discharge
point will remain the same.
We would request that speculative effluent limits be
supplied to this office as soon as possible. Thank you.

SUBJECT:
Marshall 201 Facilities Plan
Project No. C370512-01
Per your request November 20, 1987, the Technical Support Unit of the
Division of Environmental Management has completed preliminary stream impact
analyses for the Town of Marshall WWTP using a routine Level "B" model. The
results of these analyses are attached for your review. Because of the
unknown constituency of the commercial and non -specified flow in Marshall's
waste, toxicity requirements have also been attached. These requirements
may not be necessary if additional information shows that this waste con-
tains no toxics. As stated, these results are preliminary and should not be
considered as a final wasteload allocation. Final wasteload allocations
will only be developed after an NPDES permit application has been submitted.
Should you have questions or comments regarding this matter, please
feel free to give me a call.

TOXICITY TESTING REQUIREMENT
The permittee shall conduct acute toxicity tests on a ;WOK eLy basis
using protocols defined in E.P.A. Document 600/4-85/013 titled "The Acute
Toxicity of Effluents to Freshwater and Marine Organi s11,. The monitoring
shall be performed as a Daphnia up lex or Ceriodaphn�ra 48 hour static test,
using effluent collected as a 24 hour compositelhe LC50,of this effluent
using the previously stated methodology may riottt at any time be less than
O.l:l %. Effluent samples for self -monitoring urpos�esxust be obtained dur-
ing representative effluent discharg bel/O/w a l waste treatment. The first
test will be performed within thirty days from issuance o0 this permit.
All toxicity testing results r quired /a-s part of this permit condition will
be entered on the Effluent Disc arge Monitoring Form (MR-1) for the month in
which it was performed, using t e ap ropri�te parameter code. Additionally,
DEM Form AT-1 (original) i� to be sen •• tohe following address:

Test data shall be complete and accurate and include all supporting chemi-
cal/physical measurementyperformed in association with the toxicity tests,
as well as all dose/response data. Total residual chlorine must be measured
and reported if chlorine is used for disinfection of the waste stream.
Should any test data from either these monitoring requirements or tests
performed by the North Carolina Division of Environmental Management indi-
cate 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 docu-
ment, such as minimum control organism survival and appropriate environmen-
tal controls, shall constitute an invalid test and will require immediate
retesting. Failure to submit suitable test results will constitute a fail-
ure of permit condition.
