Subject: Review of Draft NPDES Permit NC0000795
Kinder Morgan SE Terminals,LLC
KMST Greensboro Terminal 1,
WPCS Physical/Chemical Grade PCNC
6907 West Market Street,Greensboro
Guilford County
Mr. Sinclair:
The Division of Water Resources(DWR or the Division)received on August 18,2021,your application
to renew the subject permit.Please carefully review the attached renewal draft to ensure your
understanding of its limits and monitoring conditions,and to correct errors, if any.
Concurrent with this notification,the Division will solicit public comment on this draft by publishing a
notice in newspapers having circulation in the general Guilford County area,as required by the NPDES
Program. Please submit your written comments(if any),to my attention,NCDEQ/DWR/NPDES no
later than November 30,2021 (approximately 30 days after receiving this document). We welcome your
written comments,but they are not mandatory.
Whole Effluent Toxicity(WET)—Since last renewal the Division has deemed annual WET testing
insufficiently frequent to adequately evaluate surface-water toxicity.Consequently,all permits statewide
with annual testing are being converted to Quarterly at renewal.It follows therefore that we have set
Quarterly WET testing as a minimum frequency for this permit.
Data Evaluation. Since last renewal,the Division understands that Kinder Morgan has made no significant
alterations to treatment/pollution-prevention processes.In keeping with current NPDES Permitting
Guidance,DWR evaluated monitoring data by applying reasonable potential analyses(RPAs)as required
by the EPA.Each parameter of concern(POC)is considered for its potential to exceed its respective
surface water-quality standard
Summary of Changes for This Renewal:
1. updated facility description(see Supplement to Permit Cover Sheet)
2. updated text for WET testing [Condition A.(3.)]
3. updated facility map
4. monitoring frequencies for the analytes MTBE and Total Recoverable Phenolics
are hereby reduced from Monthly to Quarterly.
5. increased Whole Effluent Toxicity(WET)testing frequency from Annually to
Quarterly, in accord with revised statewide policy to protect surface water quality.
6. We have added pH monitoring,as required by EPA for all industrial dischargers.

A. (2.) FLOW MEASUREMENT RATIONAL
[G.S. 143-215.1(b)] \"� )\
The Rational Method- Determination of Pe Run ff: ),z
[REF:FHWA Urban Drains anual, 2. . 'onal a (3-1)]
Q=KuCIA,w e : N\
Q = flow(peak flow ra(e in cfs or m3/se
Ku= unit conversation faq) = 1 008 for . . standard units(usually
ignored because it is so close to 1),or 0.278 for metric units
C = dimensionless runoff coefficient for the watershed, loosely defined as the
ratio of runoff to rainfall
I = intensity of rainfall [taken from the intensity-duration-frequency curves
for the specified design return period at the time of concentration,tc(in/h
or mm/h).tc=time of concentration(time after beginning rainfall excess
when all portions of the drainage basin are contributing simultaneously to
outlet flow).
A = area of tributary watershed(acres or km2)
The rational equation is used to calculate the runoff from a region,given:
• the runoff coefficient(accounts for infiltration losses in the region),
• the rainfall intensity to the region,
• the time for runoff to travel from the region's upper reaches to its outlet,and
• the region's drainage area.
A. (3.) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled"Pass/Fail Methodology for Determining Acute Toxicity In A
Single Effluent Concentration" (Revised December 2010 or subsequent versions). The monitoring shall
be performed as a Fathead Minnow (Pimephales promelas)24-hour static test.
Page 4 of 8

NPDES Permit NC0000795
The effluent concentration at which there may be at no time significant acute mortality is 90% (defined
as treatment two in the procedure document). The tests will be performed during the months of
January,April,July, and October.These months signify the first month of each three-month toxicity
testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during
representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge
below all treatment processes.
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.
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, DWR Form AT-2 (original)is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service CeIter \\
Raleigh,North Carolina)27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
days after the end of the reporting period for which the report s ma e
\wv\ 2-',
Test data shall be complete and accut‘te and include all,supporting chemical/physical measurements
performed in associatio6vith tke xicity tests, as well all dose/response data. Total residual chlorine
of the effluent toxicisample mu measured anreporfed 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
Water Sciences Section at the address cited 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. Assessment of
toxicity compliance is based on the toxicity testing quarter,which is the three-month time interval that
begins on the first day of the month in which toxicity testing is required by this permit and continues
until the final day of the third month.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Resources 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.

Discharge Monitoring Report (eD ernet application.<'
Monitoring results obtained during the previous month(S) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access,then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms(MR 1, 1.1, 2, 3)or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
following address:
