ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterjy 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(Pimephales promelas)24 hour static
test,using effluent collected as a 24 hour composite. The effluent concentration at which there may be at 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 first test will be performed after thirty days from the effective date of this permit during the
months of_SEP DEC MAR JUN
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,DEM Form AT-2(original)is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 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.

Per Dave's comments on the factsheet: 1)Ni limit was given per guideline 2) In this case we
are recommending monitoring of phenols based on narrative for Class C waters for
protection against fish flesh tainting.The predicted phenols value exceeds the allowable and
if this was a WS class stream a limit would be given. Based on the Tr designation of the WF
French Broad and for protection of the fish,I recommended the continuation of at least
monitoring for phenols. 3)Reviewed the instream data and overall the instream temp.cap of
20C for Tr class has not been exceeded,however there were a couple of summer months
where the avg was 18-19C. Only had one downstream value above 20C . Again for the
protection of the Tr and HQW designations,I don't think that continued instream monitoring
for temperature would present an undue hardship to the discharger.

Involves chrome plating and burnishing of chrome parts.
Compliance Data Review- Facility average Qw = 0.019 MGD. Following parameters
reported most times as less than detectable in the period from(6/94-5/95),however there
are months when values are recorded.#Months<DL in 0,CN(7), Cd(7), Cu (4),Pb
(7),Ni (8),Ag(5). One violation of permit limit, Cr limited @1.71 #/d,mo. avg. of 6.14
#/d in 11/94. Oil&Grease limit exceeded in 8/93.
ARO Staff Report - Recommends renewal of Permit. Noted that treatment process
modifications and upgrades of monitoring equipmenmt for chemical processes,and
installation of alarm systems have reduced the likelyhood of spills reaching the river.
Toxicity Analysis - Previous has acute monitoring for two years, after which, the
facility would go to an acute tox P/F. Will renew acute tox P/F limit. Reviewed
DMR data from 1994 thru May, 1995.DMRs had most data as none detected(ND). No
detection levels were given at all.Had to call ORC,Edward Corey to get actual detection
levels for each parameter in order to do tox analysis. Not detected could have been
considered a 0 value and the evaluation could not have been done.The detection levels are
as follows:
CN 0.002(all in mg/1)
Phenols 0.025
Cd 0.01
Cr 0.020
Cu 0.01
Pb 0.100
Ni 0.050
Ag 0.010
Zinc 0.010
O&G 1.0
TSS 1.0
Lab used is Pace Laboratories in Asheville.
Ni-all 32 observations are BDL,predicted value< 1/100 of allowable
Cd and Pb, 31 Of 32 observations are BDL. Cd predicted value< 1/10 of allowable.Pb
predicted value< 1/100 of allowable
Cn-28 of 32 obs are BDL. Cn predicted value< 1/100 of allowable
Zn-predicted value< 1/10 of allowable
Cu- 22 of 32 values BDL. Cu predicted value< 1/10 of allowable.

page 2
Cr -Predicted value> 1/10 of allowable
Ag-27 of 32 values BDL/Max.predicted Cw>allowable. Limit is needed. Since Ag is
an action level will recommend renewal of existing guideline limit.
Phenols-previously recommended to be limited because WLA indicated that receiving
stream was WS class. This was either erroneous or the class has changed, new WLA
shows class as C TR HQW. However, there is a narrative "standard" for phenols in Class
C waters that states "only such levels as will not result in fish-flesh tainting or mpairment
of other best usage. The receiving stream is also designated for trout. Phenols limit
applicable only given in WS class waters. Would like to continue phenols limit since the
predicted value exceeds the allowable conc. of 60114/1 for the 1 µg/1 standard for WS and
if protection from fish-flesh tainting is the criteria for protection then this exceedance could
taint fish.
Reviewed the Toxicological Profile for Phenol by Agency for Toxic Substances and
Disease Registry. U.S. Public Health Service . States that phenol found in aluminum
forming industry in the final effluent in concentration of 1.3 ppm(mean value)and 9.7
ppm (max. value).(page 70) As found in other media, (not water, air, soil)phenols had
been found in bottomfish from five sites in Commence Bay in Washington (page 71),@
the highest max. and overall max. concentration of 0.14 ppm and 0.22 ppm, respectively.
Telecon with Mark Hale of ESB --
Recommendation. Because of the HQW class of the facility will recommend
renewal of existing limits with some modification. Will recommend
monitoring for Ni since all the values are below detection. Will
recommend renewal of all other limits for the protection of the HQW status.
Although the tox analysis indicates that several of the parameters can be
monitored or have the limit rescinded, will continue to recommend the
effluent guidelines for this type of industry.

.0004 DEFINITIONS •
The following definitions shall apply throughout this Subchapter.
(1)Activated Carbon Beds. A physlcatrchemlcal method for reducing soluble organic material from wastewater effluent;The column-type beds used In this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she;
(2)Aerated Lagoons. A basin In which all solids are maintained In suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow-through basis;
(3)Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, agitation or d lusion;(3a) Extended
- Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4)Agriculturally managed site. Any sits on which a crop is produced,managed,and harvested(Crop Includes grasses,grains.tees.etc.);
(5)Air Stripping. A process by which the ammonium ion Is first converted to dissolved ammonia(pH adjustment)with the ammonla then released to the
atmosphere by physical means;or other similar processes which remove petroleum products such as benzene,toluene.and xylene;
(6)Carbon Regeneration. The regeneration of exhausted carbon by the use of a lumace to provide extremely high temperatures which volatilize and oxidize the
•i absorbed impurities;
(7)Carbonaceous Stage. A stage of wastewater treatment designed to achieve"seeondary'effluent limits;
'•''(8)Centrifuge. A mechanical device in which centrifugal force is used to separate solids from liquids or to separate liquids of different densk:as-
(9)Chemical Addition Systems-The addition of chemical(s)Io wastewater at an application point for purposes of Improving solids removal,pH adjustment, •
'..alkalinity control.etc.;the capability to experiment with different chemicals and different application points to achieve a specific result will be considered one
•;,. •'r:system;the capability to add chemicat(s)to dual units will be rated as one system;capability to add a chemical at a different application points for different
purposes will result In the systems being rated as separate systems;
(10)Chemical Sludge Conditioning. The addition of a chemical compound such as lime,ferric chloride,or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11)Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic,non-toxic materials from sand,gravel.
c' ' crushed stone or other similar operations.Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances; ^^^
