Subject: NPDES Permit Modification
Permit Number NC0086827
Brenntag Southeast,Inc.
Durham County
Dear Mr.Biehl:
The Division issued NPDES permit NC0086827 to Brenntag Southeast,Inc.on October 31,2001. The
Division has received your January 30,2004 proposal for permit modification at the subject facility.
In your letter,you requested that monitoring for the following parameters be removed as a permit
condition: chloroethane,chloroform,ethyl benzene,isopropyl ether,methylene chloride,methyl isobutyl ketone,
naphthalene,phenol,sec-butylbenzene,tert-butylbenzene, 1,1,1-trichloroethane, 1,3,5-trimethylbenzene,and 1,2,4-
trimethylbenzene.This request was based on the fact that these constituents were not found at detectable levels in
the effluent for at least the past twelve months(except for phenol,which was detected once and that was thought to
be a lab en-or). In addition,you requested that the limit and monitoring for bis(2-ethylhexyl)phthalate be removed
as a permit requirement since it also was not detected in effluent samples for the past year(except for once which
was discounted as a lab error). Finally,you requested that the effluent sample type for chronic toxicity be changed
from composite to grab due to extenuating circumstances at the site that make composite sampling costly,time
consuming,and less accurate in indicating the true toxicity of the effluent.
The Division has examined the effluent data from this discharge and agrees that removal of those
parameters that have not been detected for the past 12 months is appropriate. Therefore,monitoring of the following
twelve parameters will no longer be required:chloroethane,chloroforni,ethyl benzene,isopropyl ether,methylene y
chloride,3methyl isobutyl ketone,naphthalene,;xsec-butylbenzene,tert-butylbenzene, 1,1,1-trichloroethane, 1,3,5-
trimethylbenzene,and 1,2,4-trimethylbenzene.
The Division also acknowledges that it is possible that the one sampling event which showed detectable
levels of phenol and bis(2-ethylhexyl)phthalate might have reflected laboratory error rather than actual
contamination of effluent. However,permit requirements cannot be removed based upon the assumption of lab
error,but must be removed based upon accurate data. Therefore,current permit requirements for these parameters
will remain unchanged at this time.
Your request to be permitted to collect a grab sample rather than a composite sample for toxicity testing has
also been approved based upon the demonstration that the discharge,if protected from prolonged exposure to air in
the vicinity of the discharge,does not cause toxicity.
In accordance with your permit modification request and our review,the Division is forwarding herewith a
modification to the subject permit. Enclosed please find the modified permit pages. These pages should be inserted
into your permit and the old ones discarded.This permit modification is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated May 9, 1994(or as subsequently amended).
Please take notice that this permit is not transferable. This permit does not affect the legal requirement to
obtain other permits which may be required by the Division of Water Quality or permits required by the Division of
Land Resources,Coastal Area Management Act or any other Federal or Local government permit that may be
required.

Kirk,
If y'all feel that a grab would be representative, then we're fine with
it. Dawn had talked with me last week about it. It's a groundwater
remediation facility that was having problems with contamination of
their sampler from the air.
Call me if you have questions.

Permit Modification Request for NPDES Permit No.NC0086827 Date:
Brenntag Southeast Facility,Durham,North Carolina 30 January 2004
Contact:
Dear Mr. Goodrich: Jim Shilliday
ARCADIS G&M, Inc. (ARCADIS)has prepared this letter on behalf of Brenntag Extension:
Southeast,Inc. (Brenntag)to request a National Pollutant Discharge Elimination 246
System(NPDES)permit modification for the Brenntag facility located at 2000 East
Pettigrew Street in Durham,North Carolina. The facility currently operates a E-mall:
groundwater treatment system that is authorized to discharge to surface water under [e-mail]
NPDES Permit No.NC0086827.
Our ref:
As required by the permit,Brenntag monitors the treated groundwater effluent on a NC000368.0013.00002
monthly basis for a variety of volatile organic, semi-volatile organic,and inorganic
constituents via a grab sample. Brenntag also monitors the effluent on a quarterly
basis for chronic toxicity via a composite sample.
Fourteen of the volatile and semi-volatile organic compounds specified for analysis
in the NPDES Permit are flagged with the notation, "If after one year of sampling
(12 sampling events)this analyte has not been detected above the quantitation limit,
the permittee may request that the Division evaluate removing that parameter as a
condition of the permit." The historical analytical results for the 14 compounds
which may potentially be removed from the required analyte list are summarized in
the attached Table 1. The results summarized on Table 1 include all effluent
samples collected from the groundwater remediation system since it was activated in
June 2001 through December 2003.
As shown in Table 1,none of the 14 noted parameters have been detected in treated
groundwater effluent at the Brenntag facility with the exception of carbon disulfide
(which has been detected twice and is a confirmed contaminant at the site)and
Part of a bigger picture

ARCADIS Mr.Goodrich

phenol(which was detected once and the detection was thought to be caused by
laboratory contamination as this semi-volatile organic compound is not known to be
a contaminant associated with the groundwater at the site). Based on these data,
Brenntag requests that monitoring of the following parameters be removed as a ()lr ply
permit condition: chloroethane,chloroforth,ethyl benzene, iso• opyl ether,
methylene chloride,methyl isobutyl ketone,naphthal6e4MP sec-butylbenzenee,
tert-butylbenzen, 1,1,1-trichloroethan, 1,3,5-trimethylbenze`ne,:nd 1,2,4-trimetriyl ,
benzene. d ,,tu2 ( (rs t '`rz' 5-)
6 NES
In addition,Brenntag would like to request the removal of bis(2-ethylhexyl)phthalate T�
from the list of required analytes for the monthly effluent samples. This compound
is a know laboratory contaminant and it is not a constituent of concern associated
with groundwater at the site. This constituent has only been detected in one effluent
sample(sample collected on September 14,2003)out of the 32 NPDES sampling
events conducted to date. The detection of bis(2-ethylhexyl)phthalate in the effluent
sample collected on September 14, 2003,was discounted as laboratory error or
laboratory contamination as was the detection((phenol during that same sampling 6-
event. - s \ss
•�' ,DO
Brenntag also requests that the DWQ consider amending the permit to allow chronic', 1 os'
toxicity to be analyzed from a grab sample rather than a composite sample. �v �x� •0�
Currently the composite sampling procedure requires that the composite sampling UGt
equipment be placed inside a 55 gallon plastic drum which is then sealed and the air
inside the drum is purged with nitrogen. This sample collection procedure was
developed because the composite sample collection equipment is located near the
acid repackaging area and the air in this area periodically contains elevated
concentrations of ammonia gas. It was determined that the ammonia gas was
coming in contact with the composite sampling equipment over the 24 hour period
that the equipment is sampling the effluent. It is suspected that the ammonia gas was
causing elevated chlorine concentrations in the composite samples and the elevated
chlorine concentrations caused several samples collected in 2002 to fail the chronic
toxicity testing procedure.
A summary of all historical effluent sampling data(including chronic toxicity test
data)since system startup in June 2001 is included in attached Table 2. The effluent
samples have passed each quarterly chronic toxicity test beginning in October 2002
which is the first sampling event to include the equipment containerization process
discussed above. The containerization process is time consuming and costly;
therefore,we would like to eliminate the need for this process by amending the
sampling protocol to allow for collection of grab samples as opposed to composite
samples.

Subject:Regarding Permit NC0086827 for the Brenntag Facility in Durham,N C
From: "Jones,Alexandra" <[e-mail]>
Date:Tue,9 Sep 2003 14:03:52-0600
To: "'[e-mail]"' <charles.weaver@ncmaiLnet>
CC: "Shilliday,Jim" <[e-mail]>
Mr. Weaver,
Thank you for returning my call. As you requested, I am sending my
questions to you in this e-mail regarding the NPDES permit for the
groundwater treatment system at the Brenntag Durham facility.
Currently, there are thirteen VOCs and one SVOC listed as monitoring
requirements on this permit that are flagged with this qualification: "If
after one year of sampling, this analyte has not been detected above the
quantitation limit, the permittee may request that the Division evaluate
removing that parameter as a condition of the permit." None of the fourteen
qualified constituents except carbon disulfide, which was detected in
December 2002 and July 2001, have been detected since the groundwater
treatment system was activated in June 2001. We would like to request that
the permit be modified to remove the thirteen constituents from the
conditions of the permit. How should we go about this request process?
Additionally, all analytical parameters for the permit, with the exception
of chronic toxicity, are analyzed from a grab sample. The chronic toxicity
is analyzed from two, 24-hour composite samples. In previous discussions
with Matt Matthews of the DWQ, he has stated that it may be possible to
modify the permit conditions to allow chronic toxicity to be analyzed from a
grab sample rather than a composite if it can be demonstrated that the
composition of the effluent does not vary in toxicity over time. I would
like to discuss this possibility with your further, at your convenience.
Thank you,
E. Alexandra Jones, EIT

PART III
OTHER REQUIREMENTS
A. Construction
No construction of wastewater treatment facilities or additions to add to the plant's treatment capacity or to
change the type of process utilized at the treatment plant shall be begun until Final Plans and Specifications have
been submitted to the Division of Water Quality and written approval and Authorization to Construct has been
issued.
B. Groundwater Monitoring
The permittee shall, upon written notice from the Director of the Division of Water Quality, conduct
groundwater monitoring as may be required to determine the compliance of this NPDES permitted facility with
the current groundwater standards.
C. Changes in Discharges of Toxic Substances
The permittee shall notify the Permit Issuing Authority as soon as it knows or has reason to believe:
a. That any activity has occurred or will occur which would result in the discharge, on a routine or frequent
basis, of any toxic pollutant which is not limited in the permit,if that discharge will exceed the highest of the
following "notification levels";
(1) One hundred micrograms per liter(100µg/L);
(2) Two hundred micrograms per liter (200 µg/L) for acrolein and acrylonitrile; five hundred micrograms
per liter (500 µg/L) for 2.4-dinitrophenol and for 2-methyl-4.6-dinitrophenol; and one milligram per
liter(1 mg/L) for antimony;
(3) Five (5) times the maximum concentration value reported for that pollutant in the permit application.
b. That any activity has occurred or will occur which would result in any discharge, on a non-routine or
infrequent basis, of a toxic pollutant which is not limited in the permit, if that discharge will exceed the
highest of the following"notification levels";
(1) Five hundred micrograms per liter (500.tg/L);
(2) One milligram per liter (1 mg/L) for antimony;
(3) Ten (10) times the maximum concentration value reported for that pollutant in the permit application.
D. Requirement to Continually Evaluate Alternatives to Wastewater Discharges
The permittee shall continually evaluate all wastewater disposal alternatives and pursue the most environmentally
sound alternative of the reasonably cost effective alternatives. If the facility is in substantial non-compliance with
the terms and conditions of the NPDES permit or governing rules, regulations or laws, the permittee shall
submit a report in such form and detail as required by the Division evaluating these alternatives and a plan of
action within sixty(60) days of notification by the Division.
PART IV
ANNUAL ADMINISTERING AND COMPLIANCE MONITORING FEE
REQUIREMENTS
A. The permittee must pay the annual administering and compliance monitoring fee within 30 (thirty)
days after being billed by the Division. Failure to pay the fee in a timely manner in accordance with
15A NCAC 2H .0105(b)(4) may cause this Division to initiate action to revoke the permit.
