FACILITY SUMMARY:
This facility is chemical manufacturing plant that produces formaldehyde and hexamine. The facility
formerly consisted of reverse osmosis (RO) and water softeners with reject or concentrate wastewaters. The
RO and water softeners wastestreams have been removed. Currently, this facility is discharging cooling
waters associated with boiler blowdown, cooling tower blowdown water and similar wastewaters (including
fire tank blowdown). Hexion, Inc. has requested for coverage under general permit NCG500000.
MONITORING FOR GENERAL PERMIT COC NCG500676: Coverage under the general permit is
for discharge cooling waters associated with boiler blowdown, cooling tower blowdown water and similar
wastewaters. General Permit NCG500000 Part I, A. (1.) gives the effluent limitations and monitoring
requirements for such wastewaters.
BIOCIDE FORM 101 APPROVAL: Hexion was approved on April 26, 2017 by the DWR Water Science
Section Aquatic Toxicity Branch for ChemTreat CL and Hydrogen Peroxide to be discharged via Outfall
001 into Livingston Creek. Calculations predict the use of these products, at the dosage rate, will not cause
toxic impacts to aquatic life in the receiving stream, Livingston Creek. Therefore, the use of this product as
an additive to cooling water system is acceptable.

SUMMARY NOTES FOR RESCISSION OF INDIVIDUAL PERMIT NC0003395:
• The Wilmington regional office confirmed in an inspection conducted on September 30, 2016 [see
attached] that the reverse osmosis (RO) system has been taken off-line. As described regional office
inspection report:
Water softener (used for formaldehyde production make-up water) backwash is routed to the
concrete basin, which also receives the first 30 minutes of flush stormwater from the hexamine
process area. The concrete basin content is used for make-up water for cooling towers 5 and 6. All
water in these towers is evaporated.
Other cooling towers: no. 1 taken out of service, nos. 2, 10 and 11 have been replaced by new no. 3.
Nos. 3, 7, and 12 are supplied water via the plant fire tank, which receives all make up water from
Livingston Creek. The fire tank is blown down once per week. The one operational boiler currently
discharges to the Columbus County POTW. This boiler blowdown may be sent back to outfall 002
at a future date. These cooling towers and boiler have various conditioners and biocides added to
the makeup water. Plant hexamine production wastewater is sent to the Columbus County POTW.
Outfall 002 was discharging and the effluent was noted to be clear and relatively free of suspended
solids.
• The water softener was removed in June 2016, which will no longer discharge of any reject or
concentrate water via Outfall 002. Discharge form water softeners is now being incorporated into the
recycled water system.
• The facility formerly used treated process water as cooling water. Consequently, Outfall 002 was
monitored for formaldehyde. A limit violation for formaldehyde occurred in November 2012. Since
2011, the facility has cleaned, removed and/or replaced cooling towers to eliminate discharge of
formaldehyde. Notably, water from Livingston Creek is now used as cooling water instead of any
process waste stream.
• Fire tank blowdown is allowed by the general permit.
TOXICITY — The previous permit NC000395 required Chronic
using Ceriodaphnia dubia at 4.7% that was limited. See attached

RPA: The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water
quality standards, a statistical evaluation that is conducted during every permit renewal utilizing the most
recent effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The
NC RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of
zero background; 3) use of /2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between Apr2016-
Mar2017. Pollutants of concern included toxicants with positive detections and associated water quality
standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit:
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria:
Arsenic, Copper, Zinc, Fluoride, Chloride, Formaldehyde and Methanol. The individual permit
NC000395 with these parameters of concern will be rescinded. See attached RPA spreadsheets and
discussion of the implementation of the dissolved metal standard for Copper below.
NPDES Implementation of Instream Dissolved Metals Standards — Freshwater Standards
The NC 2007-2015 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as
approved.

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness -dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness and
so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on that
below), but it is also possible to consider case -specific translators developed in accordance with established
methodology.
RPA Permitting Guidance/WOBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream. If the maximum predicted value is
greater than the maximum allowed value (chronic or acute), the discharge has reasonable potential to
exceed the standard, which warrants a permit limit in most cases. If monitoring for a particular pollutant
indicates that the pollutant is not present (i.e. consistently below detection level), then the Division may
remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
Fact Sheet
NPDES COC NCG500676
Page 5

• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates
the 1 Q 10 using the formula 1 Q 10 = 0.843 (s7Q10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern and for
each individual discharge, the Permit Writer must first determine what effluent and instream
(upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and upstream
hardness samples over a period of one week. The RPA is rerun using the new data.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
= (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) + (s7Q10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1 Q 10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any have
been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in -stream ambient
conditions. This factor is calculated using the linear partition coefficients found in The
Metals Translator: Guidance for Calculating a Total Recoverable Permit Limit from a
Dissolved Criterion (EPA 823-B-96-007, June 1996) and the equation:
Cdiss =
Ctotal
1
1 + { [I( ] [satt+a)] [106] }
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used, and
Kpo and a = constants that express the equilibrium relationship between dissolved and
adsorbed forms of metals. A list of constants used for each hardness -dependent metal can
also be found in the RPA program under a sheet labeled DPCs.
Fact Sheet
NPDES COC NCG500676
Page 6

4. The numeric standard for each metal of concern is divided by the default partition coefficient (or
site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca = (s7Q10 + Qw) (Cwqs) — (s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw = permitted effluent flow (cfs, match s7Q10)
s7Q10 = summer low flow used to protect aquatic life from chronic toxicity and human health through
the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q10 may be incorporated as applicable:
1 Q 10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of water, fish, and
shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations, the discharge is considered to show reasonable
potential to violate the water quality standard, and a permit limit (Total allowable concentration) is
included in the permit in accordance with the U.S. EPA Technical Support Document for Water
Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance with
the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on 40 CFR
122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and hexavalent
chromium Water Quality Standards. As a cost savings measure, total chromium data results may be
used as a conservative surrogate in cases where there are no analytical results based on chromium
III or VI. In these cases, the projected maximum concentration (95th %) for total chromium will be
compared against water quality standards for chromium III and chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are inserted
into all permits with facilities monitoring for hardness -dependent metals to ensure the accuracy of
the permit limits and to build a more robust hardness dataset.

*Downstream hardness data from ambient station B8441000 (-1 mile downstream, see attached map) was
used in place of upstream hardness. The average of the downstream data is 41.32 mg/L. This hardness data
is utilized in the attached RPA to demonstration that the predicted maximum concentration is less than both
the acute and chronic allowable concentration. As a result, no limitation is recommended by the RPA.
Additionally, a stress test of hardness data was conducted using an RPA spreadsheet for Copper indicating
that a Total Hardness of>29.45 mg/L is required for no reasonable potential to exceed the water quality
standard for dissolved copper. The ambient stream data would indicate that Total Hardness for Livingston
Creek is well above this stress test endpoint value.

The equation for the chronic value gives the greatest result: y = 5.1329x + 32.153
If Y = 183.3 mg/L
then X = 29.45 mg/L
therefore, upstream hardness data need to be >_29.45 mg/L

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Met with Tom Buller to perform routine compliance inspection and discuss conversion of individual to
general permit.
Confirmed that RO sytem has been taken off-line. Water softener (used for formaldehyde production
make-up water) backwash is routed to the concrete basin, which also receives first 30 minutes flush
stormwater from the hexamine process area. The concrete basin content is used for make up water
for cooling towers 5 and 6. All water in these towers is evaporated.
Other cooling towers: no. 1 taken out of service, nos. 2, 10 and 11 have been replaced by new no. 3.
Nos. 3, 7, and 12 are supplied water via the plant fire tank, which receives all make up water from
Livingston Creek. The fire tank is blown down once per week. The one operational boiler currently
discharges to the Columbus County POTW. This boiler blowdown may be sent back to outfall 002 at a
future date. These cooling towers and boiler have various conditioners and biocides added to the
makeup water. Plant hexamine production wastewater is sent to the Columbus County POTW.
Oufall 002 was discharging and the effluent was noted to be clear and relatively free of suspended
solids.
Permittee is currently preparing a general permit application along with biocide worksheets for each
chemical. Permittee may also propose a new downstream sample site due to current access issues;
there may be a more accessible site which would also be more representative of potential downstream
impacts.

Subject: RE: Biocide Review - Hexion Acme Facility
Derek,
Nice talking to you this morning. The likely source of copper and zinc at the facility is from legacy production at Oak Bark
of a product called Mintrex. Oak Bark ceased production in 2011-2012. Oak Bark did not control their process or
production well and Mintrex contaminated most of the site. It is a fine dust and we suspect that it has blown all around
the plant site and entrained in cooling towers. The site knows of no other source of copper that could be impacting our
cooling tower discharges. The site has seen decreasing concentrations of copper and zinc at all of our stormwater
outfalls as well as in our 002 NPDES wastewater discharge which indicates that we are correct that the source of the
copper is from legacy Mintrex contamination.
In addition our permit application stated that blowdowns from Cooling Towers #3, #7, and #12 would be
discharged. Cooling Tower #7 has changed operation and will not be blowing down in the future. In addition Cooling
Tower #3 will also be changing operation once we receive our new air permit this year. Therefore our estimated
discharge amounts will be decreasing quite significantly. Let me know if you have any questions about this email. Thank
you,

Hexion Acme Facility has requested approval of the following chemicals, ChemTreat CL 438
and Hydrogen Peroxide. These products will be discharged into their Outfall 001 and in to the
Livingston Creek.
Calculations predict the use of these products, at the stated dosage rate, will not cause toxic
impacts to aquatic life in the receiving stream, Livingston Creek. Therefore, the use of this
product as an additive to their cooling water system at Hexion Acme Facility is acceptable.

Dear Ms. Gryzb:

Wafer Q Seict on
Permitting
Hexion is submitting a General Permit Application to replace our current Individual
NPDES Permit # NC00003395. You will see the General Permit Application attached.
We have attached the Chemical Treatement/Biocide Forms and documentation for the
Cooling Tower chemical treatment and biocide. We are also sending them to the
Aquatic Toxicology group.
Hexion discovered that our current makeup of our boiler treatment chemicals do not
meet the criteria for discharge to the creek. It is important to remember that Hexion is
not currently discharging boiler blowdown as that was not allowed under our individual
permit. We will be working with our vendor and the Aquatic Toxicology Branch to find a
treatment regimen that will meet the criteria. Hexion will not discharge boiler
blowdowns until that has been approved by the Aquatic Toxicology Branch.
Thank you for your cooperation in this matter. If you have any questions regarding this
submittal, please contact me at 910-830-2757.
Regards,

4. First Aid Measures
BRENNTAG ANIS
inhalation: Remove to fresh air. Give artificial respiration if not breathing. Get immediate medical attention.
ingestion: DO NOT induce vomiting. Give large quantities of water. Never give anything by mouth to an unconscious person. Get
immediate medical attention. If swallowed, large amounts of oxygen may be released. The distention of the stomach or esophagus may be
injurious.
Skin Contact: Hush skin with plenty of water while removing contaminated clothing. Get medical attention for irritation or burns.
Clean clothing before reuse.
Eye Contact: Flush eyes with plenty of water while holding eyelids open. Get immediate medical attention.
5. Fire Fighting Measures
Go to Section 9 for Flammable Properties.
Fire: Wear protective clothing including self-contained breathing apparatus.
Explosion: Hydrogen peroxide itself is non flammable. Contact with clothing end combustibles may cause fire. On decomposition in
contact with contaminants releases oxygen which may intensify fire. The decomposition of hydrogen peroxide will release oxygen gas,
which will increase the explosive limits and burning rate of flammable vapors.
Fire Extinguishing Media: Water, water fog
Special Information: Contact with organic liquids or vapors may cause immediate fire and explosion especially if heated or may result
in delayed detonation. Conduct all initial experiments on small scale and protect personnel with adequate shielding as reactions are
unpredictable. being affected by impurities. contaminants. etc.
6. Accidental Release Measures
Personnel with pruper protective equipment should dike and contain spill. Flood area with water and drain to a chemical sewer or
wastewater treatment plant. May be destroyed with sodium metabisulfite or sodium sulfite (L9 lbs. SO2 equivalent per Ib. of peroxide).
7. Handling and Storage
Store in a ventilated, cool area. Product freezes at -15°F. Do not get in eyes. Avoid contact with sun and clothing. Avoid contact with

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Airborne Exposure Guidelines:
HYDROGEN PEROXIDE (7722-84-1)
US. ACGIH Threshold Limit Values
Time weighted average
1 ppm
US. OSHA Table Z-1 Limits for Air Contaminants (29 CFR 1910.1000)
PEL:
1 ppm (1.4 mg/m3)
Only those components with exposure limits are printed in this section. Limits with skin contact designation above have skin contact
effect. Air sampling alone is insufficient to accurately quantitate exposure. Measures to prevent significant cutaneous absorption
may be required. Limits with a sensitizer designation above mean that exposure to this material may cause allergic reactions.
Engineering controls:
Investigate engineering techniques to reduce exposures below airborne exposure limits or to otherwise reduce
exposures. Provide ventilation if necessary to minimize exposures or to control exposure levels to below
airborne exposure limits (if applicable see above),If practical, use local mechanical exhaust ventilation at
sources of air contamination such as open process equipment
Consult ACGIH ventilation manual or NFPA Standard 91 for design of exhaust systems.
Respiratory protection:
Avoid breathing vapor or mist. Where airbome exposure is likely or airborne exposure limits are exceeded (if
applicable, see above), use NIOSH approved respiratory protection equipment appropriate to the material
and/or its components. Full facepiece equipment is recommended and, if used, replaces need for face shield
and/or chemical goggles. Consult respirator manufacturer to determine appropriate type equipment for a given
application. Observe respirator use limitations specified by NIOSH or the manufacturer. For emergency and
other conditions where there may be a potential for significant exposure or where exposure limit may be
significantly exceeded, use an approved full face positive -pressure, self-contained breathing apparatus or
positive -pressure airline with auxiliary self-contained air supply. Respiratory protection programs must comply
with 29 CFR § 1910.134.
