Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Mineral Research & Development currently operates a 0.025 MGD treatment
plant. Inorganic chemicals are manufactured at the plant. Previous WLA
was based on BPJ, which was more stringent than the WQ standard.
Facility is currently performing whole effluent toxicity tests using
the fathead minnow. -Pt. fog d Tech Support will recommend toxicity
testing be performed using the organism.CP64 Kepi E,ACtLesem/AQ.IATIGToxtacovy)
DMR data indicate the facility is capable of meeting all limits with
the exception of Zinc and occasionally NH3-N.
Permitted value for Copper is different than that recommended in
previous WLA. Region should comment if this is in error or if this is the
product of negotiations with the facility. Mineral Research and
Development appears capable of meeting the limit put into the permit.

ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Dapimid 48 hr - LC50
fATNeilD MNJNOW
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to an -WAD Mi�NoW
Freshwater and Marine Organisms". The monitoring shall be performed as a
Cerrodaphnia 48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any two consecutive toxicity
tests be less than 45 %. Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The first test will be performed after
thirty days from issuance of this permit during the months of TAN, Aea., SAL-) Dar
• 70►iet.es Paemeuts TAA (o G
The parameter code for this test if using n.,,;>,„'" "" " is �.
;f .,sing Ce i.,.ia„h .. _ _ __ __ . 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-1.
(original) is to be sent to the following. address:
Attention: Technical Services Branch
North .Carolina Division of
.Environmental Management
P.O. Box27687
Raleigh, N.C. 27611
Test data shall be: completeand 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 chlorineis 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 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 noncompliance with monitoring requirements.
