Subject: DRAFT NPDES Permit NC0022209
Motiva Enterprises, LLC
Greensboro Terminal, WPNC Grade PCNC
101 S. Chimney Rock Road, Greensboro
Guilford County
The Division of Water Resources (DWR or the Division) received on February 28, 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 August 31, 2021 (approximately 30 days after receiving this document). We welcome your
written comments, but they are not mandatory.
Whole Effluent Toxicity (WET) — The Division acknowledges Motiva's request to relax WET testing
from Quarterly to Annually. However, since last renewal DWR has deemed annual WET testing
insufficiently frequent to evaluate surface -water toxicity, and we have therefore set Quarterly WET
testing as a minimum frequency. Consequently, all permits statewide with annual testing are being
converted to Quarterly at renewal. It follows that your request must be denied.
Data Evaluation. Since last renewal, the Division understands that Motiva 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 on the supplement to permit cover sheet
2. updated text for WET testing [Condition A. (3.)]
3. updated facility map
4. BTEX, Naphthalene, Oil & Grease, and Turbidity remain POCs based on current
site usage and activities. However, these analytes not detected above lab PQLs

during the previous permit cycle; therefore, monitoring is reduced from Monthly
to Quarterly.
5. MTBE monitoring discontinued; not detected during the previous permit cycle;
Motiva has not used this fuel additive since 2010.
6. Total Recoverable Phenolics monitoring discontinued; not detected; no longer
considered POC per current permitting guidance.
Monthly Report Submittals: Federal regulations require electronic submittal of all program reports and
Monthly Discharge Monitoring Reports (DMRs); see Permit Condition A. (3.). Our records show that
Motiva has successfully registered for the Electronic Discharge Monitoring Report (eDMR) program.
Please do not continue to submit DMR hardcopy as back-up to the eDMR.
The NPDES standard conditions (Parts II, III, and IV), are part of this permit but are not included in this
draft document (cover, map, and Part I). The conditions are identical to your current permit except that
agency and division names have been updated. The latest version of Parts II, III, and IV are available
at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
Following the mandatory 30-day Public Comment period, the Division will review all pertinent comments,
if any, and take appropriate action prior to issuing an NPDES permit final.
If you have questions, please email the undersigned at [joe.corporon(a,ncdenr.gov]. In support of mandated
emergency response to Covid 19, most of NC state government currently functions remotely, therefore
correspondence via email is preferred.

Footnotes:
1. The Permittee shall submit Dischar onitoring Reports electronically using NC DWR's eDMR application
system. See Condition A. (4.).
2. Each discharge event shall b e monitored for Flow volume and duration — During periods of no flow, the
Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow
may be documented using any one of the following four (4) methods:
1) measure flow continuously via weir or flow meter (totalizer preferred)
2) estimate flow at 20-minute intervals during the entire discharge event
3) report flow based on discharge pump logs; or
4) calculate flowbasedon totalrainfallperunit area draining to the outfall
using the Rational Method [see formula, Section A. (2.)].
3. Turbidity —Effluent turbidity shall not cause receiving -stream turbidity to exceed 50 NTU. If background
turbidity naturally exceeds 50 NTU, the effluent shall not cause backgroundturbidityto increase. Any discharge
exceeding this permit limit will require sufficient instream sampling (upstream and/or downstream) to verify
compliance (effluent vs. background). [NCAC 02B. 0211(21)]
4. Where possible, the grab sample for Oil & Grease should be skimmed from the water surface ofa quiescent
(calm water) zone.
5. BTEX (Benzene, Toluene, Ethyl Benzene, Xylene), Naphthalene - Applied laboratorypracticalquantitation
limits (PQLs) must be sufficiently sensitive to detect the respective water -quality standard for each p arameter of
concern [see Part II. SectionD. (4.)].
6. Whole Effluent Toxicity (WET), Fathead Minnow (Pimephales promelas), 24-hour static test during the
months of January, April, July, and October [see section A. (3.].

A. (3.) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QUAR"1'ERLY)
[15A NCAC 02B .0500 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. 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.

NPDES Permit NC0022209
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 electronically using
the Division's eDMR system 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:

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.
