S12ecial inst ctions or Conditions
All volumes of wastewater leaving the facility must be monitored. If continuous
monitoring is not feasible, then the discharger shall record the approximate times
that discharge began and ended, along with the instantaneous flow at the time of
effluent sampling. Monitoring for Benzene, Toluene, Ethyl benzene and Xylene
using an EPA approved method to a detection level of at least 1 ppb. Limited
parameters are to be monitored twice (2) per month. Also recommend monitoring
for methyl tert-butyl ether (MTBE) using an EPA approved method. This
monitoring should be performed at the same time that the whole effluent toxicity
test sample is taken during the first five discrete discharge events and annually
thereafter. A reopener clause should be placed in the permit to allow limits to be
placed on toxicants should the facility fail its whole effluent toxicity test.

ACUTE TOXICITY MONITORING (EPISODIC)
The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in
E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pbwhales
promelas) 24 hour static test, using effluent collected as a single grab sample. Effluent samples
for self -monitoring purposes must be obtained below all waste treatment. Sampling and
subsequent testing will occur during the first five discrete discharge events after the effective date
of this permit. After monitoring of the first five toxicity tests, the peimittee will conduct one test
annually, with the annual period beginning in January of the next calendar year. The annual test
requirement must be performed and reported by June 30. If no discharge occurs by June 30,
notification will be made to the Division by this date. Toxicity testing will be performed on the
next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge 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: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
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 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 invad test.
Failure to submit suitable test results will constitute noncompliance with monitoring requi menu

Facility has a record of passing, but with the wrong test, we recommended 48 hr Daphnia and the lab now requires 24 hr
Fathead. After talking with Matt Matthews at the lab, he suggested we re -institute the 5 discrete discharges with 24 hr

Dear Ms. Smith:
:F1'iib:eo has experienced changes in the lead monitoring reau:l;ts in
the Charlotte orminal's outfall. While tOia probleln wua► t'sought
corroote,d,, monitoring results for December werci 58 u.g/1 and 32
UY/ 1.
During 1992 wlt experienced intermittent lead , exceedanceas. - Wea
engaged upon a datai)led sampling program to identify,tho ceource of
:lead, Ultimately a sample of soap used to clean the rack area
tested positive for load and Am use was immnediataly di.laconti.nued.
No exceedcncea occurred from February through November 1993 and we
laelieeved the problam had been resolved,
In the most recent cna:lyses (Doc;embor 1993) we were very slurprised
when two exceedasnc ou oQcurred. The system was immediately cleaned
asa.in and additional equipment igt being ridded as as fakil hale
polishing step. Phibro is currently waiting on authorization to
proceed with the equipment.
Should you require furt.lher• information you ma iy contact F;1: A'nk 11hiteat,
