MEMORANDUM
To: Randy Kepler
From: Farrell Keough
Through: Carla Sanderson
Subject: Benson WWTP NC0020389
monitoring requirements
The Town of Benson sent a letter dated November 2, 1993 questioning the necessity for requirements on
Copper, Lead, Chromium, Zinc, Cadmium, Silver, and Cyanide. The following is a brief outline of the reasons
involved regarding these requests; the recommendations for each are based on an attached data sheet reflecting
the Benson WWTP Effluent, Influent, and Effluent data from Johnson & Johnson, (Benson's only significant IU).
Before addressing each parameter, a brief history of the facility would be pertinent. After receiving their last
permit, (1988) the facilities lab lost its certification. Benson continued to send in their Daily Monitoring Reports based
on analysis from their uncertified laboratory. Unfortunately, the Water Quality Section did not pursue Benson's failure
to obtain re -certification and they continued to submit DMR's based on their lab's analysis. The data from these
reports was used to determined their 1993 permit limits, but now both the facility and the Raleigh Regional Office, (as
well as Pretreatment) are contesting the applicability of this data for interpreting the 'actual' end -of -pipe toxicants
discharged by the Benson WWTP. They are requesting that we view Benson's previous DMR data as invalid and not
use it. As a mechanism to encourage our review of the requirements for this permit, Benson has sent in data
representing various points of exit and entry into their plant over the past four or five months. The following is a brief
synopsis of said data and its relation to our permit recommendations.
Cadmium: the limit recommended for this parameter was based upon an "actual influent loading" value given by
Pretreatment. Re-evaluation of the data by Pretreatment indicates that the previous value was too high and
the current influent loading is negligible. Our recommendation, based on this information would be to drop
both the limit and monitoring requirements.
Chromium: the limit recommended for this parameter was based upon an "actual influent loading' vale( given by
Pretreatment as well as what was "permitted out" by the facility. Re-evaluation of the dato by Pro-eatment
indicates that the previous value, (actual influent loading) was too high and the currer : inf;uen; ir:adii - is
negligible. A positive 0.071 mg/I was recorded in November of 1993, but this was i,,r;uent from
uncontrollable sources and carries a high 'default' removal rate. Our recommendation, based on this
information would be to drop both the limit and monitoring requirements.
Copper: the monitoring requirement recommended for this parameter was based on both Pretreatment
figures from the headworks as well as the suspect monitoring data from the facility. The effluent data from the
facility is indicating above standard levels on a regular basis. Due to the nature of this discharge, (i.e. effluent
dominated stream) Technical Support would recommend continued requirement of their NPDES
monitoring.
Cyanide: the limit recommended for this parameter was based upon a "permitted industrial load" value given by
Pretreatment. Re-evaluation of the data by Pretreatment indicates that value was too high. Our
recommendation, based on this information would be to drop both the limit and monitoring requirements.

Town of Benson NC0020389
Lead: the limit recommended for this parameter was based on both Pretreatment figures from the
headworks as well as the suspect monitoring data from the facility. Effluent data, (from a certified laboratory)
indicates strong potential for positive values to be discharged. Also, current standard operating procedures
require that all major municipal dischargers monitor, (at least) for lead. Taking both these aspects into
account, Technical Support would recommend this parameter under -go a monitoring requirement to validate
that no water quality violations could take place.
Nickel: the limit recommended for this parameter was based on both Pretreatment figures from the
headworks as well as the suspect monitoring data from the facility. The very limited effluent data, (facility only
took one months worth) coupled with the positive values for nickel from Johnson & Johnson indicates a
need for monitoring, which we would recommend be placed in Benson's Long Term Monitoring Plan through
their Pretreatment Program. ✓ -+0 If iN LTr4P —
Zinc: the monitoring requirement recommended for this parameter was based. on both Pretreatment
figures from the headworks as well as the suspect monitoring data from the facility. The effluent data from the
facility is indicating positive levels on a regular basis. Due to the nature of this discharge, (i.e. effluent
dominated stream) Technical Support would recommend continued requirement of their monitoring to be
placed in their Pretreatment LTMP.
Silver: the limit recommended for this parameter was based upon an "actual influent loading" value given by
Pretreatment as well as what was "permitted out" by the facility. Re-evaluation of the data by Pretreatment
indicates that the previous value, (actual influent loading) was too high and the current influent loading is
negligible. No positive values were recorded 1993. Our recommendation, based on this information would
be to drop both the limit and monitoring requirements.

Farrell, here's the Benson data. I added a third "chart" for each set of data, where all values
reported as less than detection are averaged as zero. Please be aware the top chart for each
location disregards BDL values altogether (I didn't say this while we were meeting). This
third chart treats them as zero (the second chart treats them as 1/2 the detection level). We
often use either the 1/2 average or the zero average when we are preparing data; by that I
mean we derive both and see what the effect of each would be and then decide. I would
request you do this for lead (the only pollutant we decided needed an NPDES requirement),
that is use the "zero" average of 0.0005 mg/1 at the POTW effluent and see whether an
effluent monitoring requirement is still needed.
I spoke with John Alt at Benson and he said he meant all metlas, including nickel, cadmium,
and silver. He will make a handwritten correction on his copy of his letter clarifying that he
mean't all metals in the draft permit, and send it out Monday.

January 1992 thru September 1993. Please note that as of June
1992, the combined sample was obtained. at Pipe 001 after the
installation of the flow meter, pH meter and temperature probes.
Trend analyses of BOD5,,chromium, copper, lead, oil & grease, pH,
total phosphorus, total suspended solids, and zinc were generated
for combined waste stream (.total effluent) through September 1993.
If I can be of further assistance, please contact me at

Subject: Request to delete NPDES Metal Monitoring Requirements -
Dear Mr_ Howard
Our NPDES Discharge Permit is in the process of being
renewed, at this time I would like to take the opportunity to
request that the metals monitoring requirements (ie_ Copper,
Lead, Cori m, Zinc and Cyani p) be deleted from our renewed
NPDES Discharge Permit. I have included with this letter
supporting data from our one industry, also from our plant effluent
sample analysis of the metal parameters for the months of July through -
October 1993 from Southern Testing and Research commercial labs in
Wilson NC_
Our only source of metals since our existing plant started up in
July of 1980, has been from uncontrollable residential domestic
sewerage and small businesses (ie. clothing stores, restaurants
etc.). At the present time we have no radiator shops or any type
of metal plateing businesses discharging into the Benson sewer
system_
Since December of 1986, Johnson & Johnson, our one significant
industrial user, has voluntarily monitored their metals on a
monthly basis, this was in addition to the monitoring
required by their Pretreatment Permit issued to them by the
Town of Benson_ In all that time (Dec. 1986 to July 1993)
only one monthly report (Jan 1992) showed other than trace amounts of
any metals_ After a joint investigation by Town and J&J personnel,
the elevated metal values were found to be due to a change in
commercial laboratories. J&J contracted Chemical & Environmental
Technology Inc_ in Research Triangle Park in November of 1986 to
G

sample and analyze their monthly samples until December 1991.
In January 1992, J&J changed to Burlington Research Inc_ for thei__,
sampling and analysis_ When the Burlington Research employee set�,-
up their portable sampler to collect the ,January 1992 samples, he
extended the sampler suction line all the way to the bottom of the
sampling manhole_ In the course of sampling during the next 24
hrs. the sampler picked up quite a bit of sediment in the manhole,
which no one knew was there and had been concentrating the trace
metals for quite a while. Subsequently J&J thoroughly cleaned the
sampling manhole and regularly checks it now for any sediment
build up. Since that time, (Jan_ 1992) no metal values have shown
more than insignificant trace amounts as shown in the included
data and graphs derived from J&J's monthly Pretreatment IDMR
reports and analysis of the treatment plants effluent_
Originally the Metal monitoring requirements were added to our
NPDES Discharge Permit ONLY because the State Pretreatment
Division would only approve the Benson Pretreatment Program if we
developed a set of local metal.limits and NOT because we had any
problems with metals in our effluent and waste sludge. At the
present time the only metal limits in J&J's Pretreatment Permit
are the local limits, and then only because the State
Pretreatment Division requires that they be included in ALL SIU
Permits. Johnson & Johnson is classed as an Significant
Industrial User only because their discharge flow volume
constitutes approximately 40% of the Towns total influent at the
wastewater treatment plant and for no other reason. Also by deleteing
the Metals analysis requirement, which are sent out to a commercial
laboratory, will thereby reduce the cost of our laboratory program by
50 to 60 dollars per month. I am sure that ,you realize that small
town budgets are very limited in funds and that operating cost
reduction in any area, no matter how small, is very helpful_
Therefore as Town of Benson Pretreatment Program Director and
Superintendent (ORC) of the Benson Wastewater Treatment Plant, on
the Town of Benson's behalf and by authority of the Benson Board
of Commissioners, I request that the monitoring requirements for
Copper, Lead, Zinc, Chromium and Cyanide in our NPDES Discharge Permit
# NC 0020389 be deleted from our renewed State Discharge Permit when
issued_. If you need any additional data or have any questions please
feel free to call me at the treatment plant from 8:00 to 10:30 AM and
12:30 to 5:00 PM Phone # [phone].
Sincerely,
John D. Alt Sr.
Supt_ Benson W.W.T.P. &
Pretreatment Program Director
