A. (4.) ACUTE TOXICITY PASS/FAIL LIMIT (Quarterly
The permittee shall conduct acute toxicity tests'on a auarterli,basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity
In A Single Effluent Concentration" (Revised-July, 1992 or subsequent versions). The monitoring
shall be performed as a Fathead Minnow(Pimephales promelas) 24 hour static test. The effluent
concentration at which there may be at no time significant acute mortality is 90% (defined as
treatment two in the procedure document). Effluent samples for self-monitoring purposes must be
obtained during representative effluent discharge below all waste treatment. The tests will be
performed during the months of March,June, September and December.
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 TGE6C. Additionally, DWQ Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical
measurements peiformed 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 there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity(AT)
test form indicating the facility name, permit number, pipe number, county, and the month/year of
the report with the notation of"No Flow" in the comment area of the form. The report shall be
submitted to the Environmental Sciences Section at the address cited above.
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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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 Water Quality 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 follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

Permit NC00003I1
A. (5.) CHRONIC TOXICITY LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 0.55%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined
in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998,
or subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised-February 1998) or subsequent versions. The tests will be performed during the months
of March, June, September, and December. Effluent sampling for this testing shall be performed
at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised-February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment,"collection methods, exposure regimes, and further statistical methods are
specified in the"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality

later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and
all concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT)
test form indicating the facility name, permit number, pipe number, county, and the month/year of
the report with the notation of"No Flow" in the comment area of the form. The report shall be
submitted to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality 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, minimum control organism reproduction, and appropriate environmental
controls, shall constitute an invalid test and will require immediate follow-up testing to be completed
no later than the last day of the month following the month of the initial monitoring.

forms. The processes performed on-site are metal stamping, metal forming, chrome plating and
zinc plating. The facility is located near Rosman, North Carolina and discharges to high quality
waters in the French Broad River Basin. The NPDES permit for M-B Industries covers three
outfalls. Outfall 001 discharges process wastewater that has undergone physical/chemical
treatment and falls under federal effluent guidelines (40CFR 433.13). Outfall 002 consists
entirely of non-contact cooling water, and Outfall 003 discharges treated groundwater.
Reasonable Potential Analysis
Reasonable potential analysis was conducted for Outfall 003: As, Trichloroethene, Cd, Cr,
Tetrachloroethene, CN, Cis-1,2 dichloroethene, Pb, Se,Ag,Zn, and for Outfall 001: Cd, Cr, Cu,
CN, Pb,Ni,Phenols, Ag, Zn(please see attached). A separate RPA for acute standards for CN
was also calculated for both outfalls. (please see attached).

Dear Ms.Sprinkle,
Please accept the following narrative as our Sludge Management Plan:
The Waste Water Treatment Plant located at M-B Industries,Inc.was constructed to
precipitate any metals and or grinding solids introduced in the influent from the
Plating and finishing processes.The influent arrives at the WWTP in two 4000-
gallon holding tanks where itis continuously mixed to prevent settling.Air pumps
move the product to Treatment Tank no. 1 where caustic soda in introduced with
agitation in order to increase the PH level ata range of 11 -12. Gravity continues on
to Treatment Tank no.2 for the introduction of Ferric Chloride(Coagulant).
Treatment Tank no.3 introduces Quaternary Acryl amide Copolymer(Flocculent).
Both 2 and 3 continue to mix thoroughly.Gravity continues to move product
through a clarifier where the metals and solids precipitate to bottom.Air pumps
move the sludge to a conical shaped hopper.Settling continues and the sludge is fed
into a filter press at which time 90 percent of the water is remove and pumped back
to the head of the plant for reprocessing.After couple of hours the filter press is
opened and the sludge cake is remove from the filter screens into an electrically
fired/auger agitated dryer where the F006 waste can be dried to a consistency of
baby powder.From the dyer the F006 falls Into a 55-gallon drum ready for the
hazardous landfill. Parts Cleaning Technology is the Carrier @$210.00 per Drum
and PSC Phillips Services,Inc.is the landfill_Water from the Clarifier is gravity fed to
Treatment tank no.4 to adjust the PH to a range of 6-9 before the effluent is
discharge into the West Fork of the French Broad River.
if have any questions please call me 828-862-4201. ag@ ..rtgWg D

Dear Mrs.Sprinkle and Mr.Weaver,
On the behalf of M-B Industries, Inc., I would like to request renewal of
NPDES permit no.NC0000311. And in the same request,please accept my apologies
for being tardy in submitting this renewal. Being a manufacturing company whose
every product can be purchased in China,we have witnessed some uncertain
challenges during these past couple of years. Challenges that had our thoughts of
not performing metal finishing and relying on outside contractors to provide this
service. Upon reviewing the cost associated with this strategic undertaken,we have
decided to continue metal finishing here at M-B Industries, Inc. Our only changes or
improvements to the WWTP have been structural. Primarily replacement of
corroded metal supports and repainting.Normal wear and tear maintenance
continues.
We look forward to a continuation of our NPDES permit. If you have any
questions or concerns,please contact me and or Wade Sanders (operator in charge).
Regards,
Edwin Morrow
