E. Director January 28, 2013 John E. Skvaria, III Secretary Subject: Response to NPDES CEI Momentive Specialty Chemicals, Inc. NPDES Permit No. NCS000156 The Division of Water Quality received your responses to the Compliance Evaluation Inspection (CEI) report dated July 30, 2012. A review of the information provided was conducted. Thank you for the thorough response to each item listed in the CEI. The responses were very helpful in providing clarification to better understand both structural and non structural best management practices (BMPs) implemented by the company to address stormwater quality. DWQ would like to be advised of any outcome concerning the investigation into the results for formaldehyde concentrations found in the stormwater discharges. Your response indicated the potential for a false positive due to the required acid addition for sample analyses. Momentive requested clarification from DWQ for Comment #7 of the CEI report. Attached is a copy of Item IVB of EPA Form 2F for your consideration. Please continue to monitor the stormwater outfalls both qualitatively and quantitatively in accordance with the permit requirements and continue monitoring toxicity as defined in Appendix A_ The Division is hopeful that continued improvements in structural best management practices as well as improved housekeeping will significantly improve the stormwater discharge quality. The implementation of capturing the first flush in the hexamine, special projects and formaldehyde areas for utilization within the production facility should help improve the quality of the stormwater discharge from those areas. If continued gross exceedances of the benchmarks continue, the Division of Water Quality may require Momentive Specialty Chemicals Inc. to implement an in stream study to determine the effects of the stormwater discharges form this site to the receiving waters. This facility is deemed compliant with the requirements of the Stormwater Pollution Prevention Plan and the monitoring requirements imposed in the permit as of the date of the last inspection (February, 2012). 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Coleen H. Sullins, Director Division of Water Quality This letter is in regard to a site inspection that was conducted on October 1, 2008. Details of the inspection are enclosed for your review. The purpose of the inspection was to gain an understanding of the portion of the subject permitted facility (former Wright Corp.) that is now operated by the Oak -Bark Corporation. It will be necessary for Oak -Bark to apply to the Division for permit coverage to operate the two lined and covered Kelly Ponds as a closed loop recycle system_ Although, the facilities used to be used as a closed loop recycle system and are now only used to store wastewater and sludge, the Division's Central Office determined that the recycle permit would be appropriate in lieu of continuing permit coverage as a groundwater remediation facility. I have enclosed instructions, fee schedule, and an application for coverage under the closed loop recycle permit.

The site was initally permitted as groundwater remediation but no groundwater remediation ever occurred. The permit was initially provided to the Wright Corp. and covered the operation of two 2.3 MG lined and capped ponds (known as the Kelly Ponds) and one .50 MG lined pond. The Kelly ponds have MW 22,23,25,& 26 and the .5 MG pond has MW 6,7, & 9. The ponds were used to store production wastewater for reuse into evaporative chiller towers (formaldehyde and hexamine plants). The former Wright Corp site now includes two different entities (Oak -Bark Corp. and Hexion Speciality Chemicals). Oak -Bark wishes to have the Kelly Ponds repermitted and no longer uses them for industrial contact wastewater recycling. They are physically disconnected from the industrial area and have received no wastewater contributions since December of 2006. Oak -Bark wishes to eventually remove stored wastewater and solids from the two Kelly Ponds for proper disposal. Hexion will be requesting permitting the .5 MG lined pond for closed loop recycled wastewater with in the near future. I have enclosed an application for permitting a closed loop wastewater recycling facility. Since the facility is existing, some of the application submittal requirements will not have to be presented. It will not be necessary to provide application information relative to environmental assessments, certificates of convenience & public necessity, & water balance. The wastewater analyses of the stored wastewater should also include tests results for determining the wet weight concentrations of hexamine, formaldehyde and formic acid for required toxicity test parameters. It will not be required to fully characterize the stored wastewater and sludge at this time. However, if the Kelly Pond contents are proposed to be land applied via beneficial recycling as soil amendment/ fertilizer, additional waste characterization of wastewater and sludge during the land application permitting activity would include the following: Hazardous characterization- ignitability, corrosivity, reactivity, toxicity characteristics leaching procedure. Contaminants & other parameters - arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium, zinc, aluminum, ammonia -nitrogen, total keldahl nitrogen, nitrate -nitrite nitrogen, calcium, magnesium, percent total solids, pH, plant available nitrogen by calculation, phosphorus, potassium, sodium & fecal coliform bacteria.

A Compliance Sampling Inspection (CST) was conducted as part of the Multimedia Inspection. The facility's self -monitoring program was evaluated in the areas of records and reports, flow measurement, and sampling procedures. EPA collected and analyzed samples at the final effluent discharge (outfall 002) to determine if the facility was meeting the self -monitoring requirements specified in the NPDES permit_ In addition, samples -were also, collected ait the Storrnwater Outfall 006 and Industrial User Outfall 001. The following personnel participated in the inspection: Name Organization Phone Number Joe Compton EPA (706)355-8733 David Abbott EPA (404) 562-9631 Nancy McKee EPA (404) 562-8674 Ron Mikulak EPA (404) 562-9233 Mike Neill EPA (706) 355-8614 Briars Herndon EPA Contractor (706) 354-5503 Bobby Nelms NCDENR ' (910) 602-3329 Marvin Freeman Oak Bark (910) 655-2263 Wilber Lewis Oak Bark (910) 655-2297 Dave Swart Hexion (910) 655-2263 April Hanson Hexion (910) 655-2263 Michael West Hexion (910) 485-9221 Joel Fanti Hexion (910) 655-2263 Phil Busovne Hexion (910) 274-8330 Martin Lowery Hexion Contractor (336) 259-8047 SUMMARY The facility's overall self -monitoring program was considered to be satisfactory, with the exception of one flow measurement deficiency and two minor record keeping deficiencies. The SESD Project Number 08-0590 Page 5 of 13 flow measurement deficiencies at outfall 002 had a major impact on the reliability of the flow data submitted on the discharge monitoring reports. The sampling results indicated that all parameters were within NPDES permit limits. FIELD EVALUATION A detailed discussion of each area evaluated is contained in the following sections, which corresponds to the areas evaluated in Section "C" of the NPDES Compliance Inspection Report Form (EPA Form 3560). Deficiencies identified during the inspection are followed by their respective Regulatory Requirement. Suggestion's are included whichare intended to improve the operation of the facility. 1. Facility Site Review Hexion Specialty Chemicals, Inc. processes formaldehyde and anhydrous ammonia to produce hexamine and specialty Kenton resin products. The facility operates under three permits originally issued to Write Corporation which has now become two separate facilities (Oak -Bark Corporation and Hexion Specialty Chemicals, Inc). Both facilities share the same site. Presently, Hexion takes responsibility for all stormwater discharges although some of the stormwater originates on Oak -Bark property. The stormwater permit issued under the former company's name (Write Corporation NCS000156) expired on February 28, 2005. Under the present name, Hexion Specialty Chemicals, Inc there are two permitted process discharges. One.treated process wastewater discharges to the Columbia County Wastewater Treatment Plant under the Industrial User Permit number IUP 001 via outfall 001. The other wastewater discharges to Livingston Creek under the NPDES Permit number NCO003395 via outfall 002 Additionally, Hexion trucks wastewater to the Sampson County Landfill for solidification and final disposal. The process wastewater (outfall 001) was treated in the following manner: o three flow equalization tanks; one.air stripper; • ion exchange -- three deionization units; • neutralization — pH adjustment; and e five intermediate flow equalization tanks Treated wastewater (23,000 to 28,000 gallons per day) was discharged to the Columbia County WWTP via 1UP outfall 001 The Hexion designated NPDES outfall 002 mainly consist of non -contact cooling water. However, the permit description includes the permitted discharge of reverse osmosis reject, softener backwash, water softener regenerant, firewater tank blowdown, and similar wastewaters. The non contact cooling water discharges to Livingston Creek via outfall 002. SESD Project Number 08-0590 Page 6 of 13 Storrwater was discharged under the expired permit (NCS000156) via SW outfalls 001-007. The stormwater receiving waters are designated as Mill Creek and Livingston Creek, both are class C streams in the Cape Fear Basin. Rating: Satisfactory. 2. Permit The NPDES permit for outfall 002 became effective on September 1, 2007 and will expire on December 30, 2011. The Industrial User Permit for outfall 001 became effective on February 1, 2008 and will expire on April 2, 2012. The Stormwater permit for outfalls 001-007 became effective on March 1, 2000 and expired on February 28, 2005. The facility had applied for a new stormwater permit; however, the finalized permit remained in litigation. Inspection observations verified the permit information regarding the name and description of the .facility, the location of the permitted outfalls, and the name and location of the receiving waters. Rating: Satisfactory. 3. Records and Repo The facility's records consisted of discharge monitoring reports (DMRs), work sheets, calibration records, laboratory reports, and chain -of -custody forms. Records and reports for April and May 2008 were checked for agreement with NTDES self -monitoring requirements regarding sampling documentation, equipment calibration, and reporting of parameter concentrations and loadings. The facility operator analyzes pH, conductivity, dissolved oxygen, temperature, and total residual chlorine on site. The remaining samples were sent to Environmental Chemist Inc, in Wilmington, North Carolina for analysis. Deficiency: The values for field measurements were written on the operator's glove and discarded after transferring the information to the work sheets. Rep_ulatory Requirement As specified in 40 CFR, Part 122.41 0)(2), " records of monitoring information shall be maintained for a period of at least three years." This includes anything that measurements are written on. Suggestion The operator could maintain initial measurements in a small note book when in the field, transfer the data to the work sheets after returning to the laboratory, and maintain the notebook for a period of not less than three years. Deficienev: The dissolved oxygen calibration records consisted of a check mark for verification. Temperature, slope and dissolved readings were not recorded. Regulatory Requirement: As specified in 40 CFR, Part 122.41 6)(3), records of monitoring information shall be maintained for a period of at least three years. The records shall include: SESD Project Number 08-0590 Page 7 of 13 M a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling or measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. Rating: Satisfactory. 4. Flow Measurement Effluent flow at outfall 002 was instantaneously measured at the 60' V-Notch weir. The weir was located in a structure just prior to the waste stream discharge to a swampy area leading to Livingston Creek. An instantaneous flow comparison between the facility personnel and EPA, personnel indicated that the facility was reading 5.0 % higher. than EPA. This is within the allowable +/-10% accuracy range. Deficiency: Although the facility's flow measurementwas within the allowable +/-10% accuracy range, the two readings should have compared more favorably. The permittee measured the head on the weir plate from the top of the weir to the water level. The table used to convert that measurement was not a standard conversion table. One source for the correct conversion table is found in the (USDI Water Measurement Manual, Third Edition, 2001). Re ulatory Requirement: Head readings for V-notch sharp crested should be measured upstream of the weir plate a distance of four times the estimated head over the weir crest_ (USDI Water Measurement Manual, Third Edition, 2001). Deficiency: The weir plate was not plumb. Regulaton Requirement: The upstream face of the weir plate should be smooth and in a vertical plane perpendicular to the axis of the channel (USDI Water Measurement Manual, Third Edition, 2001). Deficiency: The weir angle was -not precise. Deficiency: The weir approach channel was overgrown with vegetation. Regulatory Re uirement: Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to insure the accuracy and reliability of measurements of the monitored discharges. The devices shall be installed, calibrated, and maintained to insure that the accuracy of the measurements are consistent with the accepted capability of that type of device (USEPA NPDES Compliance Sampling Inspection Manual, MCD-51). Rating: Unsatisfactory SESD Project Number 08-0590 Page 8 of 13 Effluent flow at outfall 001 was measured using a Seametrics FT420 impeller flow meter. Rating: Satisfactory Effluent flow at outfall 006 was based on a calculation using total area and the amount localized rainfall. Rating:" Satisfactory 5. Sampling Outfall 002-EPA and the permittee collected and analyzed grab samples at outfall 002 for pH, chlorine, dissolved oxygen, temperature, and conductivity. Effluent grab samples for BOD5, ammonia, total dissolved solids, metals, total nitrogen, fluoride, and total phosphorus were collected by EPA and the permittee. The permittee iced the samples and sent them to Environmental Chemist Inc, in Wilmington, North Carolina for analysis. Analytical results did not exceed the NPDES permit limits. Table 1 summarizes EPA and Hexion sampling results from outfall 002. Contained within the table are only those results that met or exceeded the minimum detection limits. A complete list of results, both EPA and Hexion are available upon request. Outfall 006-An effluent grab sample at outfall 006 was collected for pH and analyzed on site by EPA. Additionally, effluent grab samples were collected for BOD5, ammonia, metals, total Kjeldhal nitrogen, NO2-NO3, total phosphorus, extractable organic compounds, and volatile organic compounds. Sample results did not indicate the presence of parameter concentrations thought to be harmful to the environment. Table 2 summarizes sampling results from outfall 006. Contained within the table are only those results that met or exceeded minimum detection limits. A complete list of EPA results is available upon request. Outfall 001-EPA collected grab samples at outfall 001 for pH and temperature. These parameters were analyzed on site by the EPA. Additionally, effluent grab samples were collected for BOD5, ammonia, metals, total nitrogen, fluoride, total phosphorus, extractable organic compounds, and volatile organic compounds. Parameter concentrations are below those thought to be harmful to the biological treatment process. Table 3 summarizes sampling results from outfall 001. Contained within the table are only those results that met or exceeded minimum detection limits. A complete list of EPA results is available upon request. 6.

Accordingly, we are forwarding the attached NPDES discharge permit. This permit 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). This final permit includes the following changes from your current permit: ➢ The processed wastewater discharge (outfall 001) has been eliminated. This discharge is connected to Columbus County Publicly Owned Treatment Work (POTW). - ➢ A formaldehyde limit of 7.48 mg/L has been added to outfall 002 because the parameter presented a reasonable potenti to exceed the NC water duality standard based on a statistical analysis of the effluent data. ➢ A total residual chlorine (TRC) limit has also been added to outfall 002. The limit will be effective on March 1, 2r09 Monthly monitoring is required beginning on September 1, 2007. See the attached TRC policy memo for details. ➢ Monthly monitoring for various toxicants, and quarterly whole effluent toxicity testing requirements have been added to this permit because the IFl6sion has adopted a permitting strategy for all reverse osmosis (RO) and ion exchange (IE) dischargers across the State. These requirements reflect the minimum constituents and monitoring frequencies for these types of discharges. ➢ The Division understands that Hexion Specialty Chemicals is currently investigating the potential to connect the reverse osmosis reject and water softener backwash sources to the Columbus County POTW. Hexion should be aware that this type of wastewater may cause an aquatic toxicity problem in the effluent from Columbus County POTW. The Division recommends that pilot studies be performed for whole1°` Carolina effluent toxicity to simulate the addition of this type of wastewater into the Columbus �IVat4lr 1 North Carolina Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 Phone (919) 733-7015 Customer Service Internet: vvww.ncu-a15Mu-ality-per Location: 512 N.

DENR/DWQ/NPDES UNIT FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES PERMIT NCO003395 INTRODUCTION The Hexion Specialty Chemicals, Inc. — Acme Facility, herein called the Acme Facility or permittee, requires a National Pollutant Discharge Elimination System (NPDES) permit to discharge treated wastewater to the waters of the state. The permittee's 5-year NPDES permit expired at midnight on December 31, 2006. The Company requested timely renewal of their permit, so they are currently operating under the permit issued September 30, 2003. This Fact Sheet summarizes background information and rationale ,l.sed by the Division to determine permit limits and monitoring frequencies. FACILITY DESCRIPTION Acme Facility is a privately owned organic chemical manufacturing plant utilizing a biotrol wastewater treatment facility to treat industrial wastewater. The treatrnent system utilizes holding tanks, ion exchange units, bioreactors, clarifiers, bag filters and discharge tanks. Table 1. Summarizes the receiving stream characteristics and facility description. Table I.

No wastewater is discharged from this process; however, the formaldehyde is then reacted with anhydrous ammonia to produce hexamine, an organic chemical in the Standard Industrial Classification (SIC) 2869 group. This particular SIC is regulated under 40 CFR 414, subpart H — Specialty Organic Chemicals. However, the facility now discharges all its process wastewater into Columbus County Wastewater Acme Facility Fact Sheet NPDES Renewal Page 1 of 3 Treatment Plant. The effluent outfall 001 ' has been eliminated at the request of the Division. The only surface water discharge left at the facility is utility water.(outfall 002). The facility discharges the utility water into the Livingston Creek. For the past three years, the monthly average flow of the utility water varied within the range of 0.002 — 0.028 MGD as reported in the Discharge. Monitoring Report (DMR), see the table for details. Livingston Creek suffers from low dissolved oxygen whose sources are listed unknown (Cape Fear River Basinwide Plan, 2005). REASONABLE POTENTIAL ANALYSIS (RPA) To establish a list of pollutants of concern (POCs), the Division examined Acme Facility's permit application, three years of Discharge Monitoring Reports (January 2004 through March, 2007), and the basin plan. Reasonable potential analysis (RPA) was performed on formaldehyde based on monitoring required in the current permit and the results of the RPA is as follows: Formaldehyde — The maximum predicted concentration was determined to be greater than the allowable concentration. A limit of 7.48 mg/L and monthly monitoring has been added to this permit. TOTAL RESIDUAL CHLORINE (TRC) The Division has implemented TRC policy to protect aquatic life in the waters of the State and has adopted aquatic life standard for TRC. The permittee currently has high concentration of total residual chlorine in the effluent so the facility is subject to the Division's TRC guidelines. A TRC limit of 28 ug/l has been added to this permit to be consistent with the Division's TRC policy. COMPLIANCE REVIEW DWQ — The Wilmington Regional Office (WiRO) staff conducted an annual facility inspection and Thomas Moore prepared a staff report dated October 16, 2006. The facility was in satisfactory condition and in compliance with the NPDES permit at the time of the inspection.

PART II - BACKGROUND AND HISTORY The facility has been previously permitted to discharge -process wastewater from Outfall 001 and non -contact process -cooling water from Outfall 002. .The permit was modified September 30, 2003 to include effluent limitations for OutfalI 001, calculated using a methodology agreed upon by the Division of Water Quality (DWQ) and Wright Chemical. This methodology was communicated to Wright Chemical in the Division's February 25, 2003 letter summarizing the review of the flow monitoring study. The facility entered into a Special Order by Consent with the North Carolina Environmental Management Commission (EMC) on 08/20/2004. OrrMay 4, 2005, the Special Order by Consent (EMC WQ No. 05-003) was issued. Wright Chemical did not believe they could meet the effluent permit limitations (effective on October 1, 2003) specified in the modified NPDES Permit NCO003395 for 5-Day Biological Oxygen Demand (BOD-5) and Total Suspended Solids (TSS). As a result of the agreement under the SOC, relaxed limits. were given for BOD-5 (12.8 lbs/day monthly average and 34.0. Ibs/day daily maximum) and TSS (16.2 lbs/d monthly average and 51.9 lbs/d daily maximum). It should be noted that based on a review of the DMR data submitted between October 2003 to present, the facility would have met the more stringent limitations given in their permit modification effective October 2003 without the relaxed limitations given in the SOC. Under the SOC, Wright Chemical agreed to achieve final compliance by eliminating the permitted effluent discharge by connecting to a POTW or comply with the final effluent limitations specified in NPDES Permit NC0003395. Specifically, the SOC States in Section 2. (b.) 1): "On or before July 1, 2006, eliminate the permitted effluent discharge by connection to a Publicly Owned Treatment Works (POTW) operated by Columbus County, or complete actions necessary to achieve compliance with final effluent limits contained in the permit while continuing the permitted discharge". Prior to the SOC, two wastewater streams, described later in this report, comprised the influent wastewater streams routed to the wastewater treatment plant (i.e. Biotrol system). As specified in the SOC, the facility agreed to eliminate the effluent discharge from Outfall 001 by connection to a Publicly Owned Treatment Works (POTW) operated by Columbus County. The Columbus County POTW, located adjacent to the Wright Chemical facility, completed start-up in late July 2006. The completion of the startup of the POTW was after the final SOC compliance date of July 1, 2006. Wright Chemical began discharging wastewater to the POTW in late July 2006. However, only one of the influent wastewater streams has been routed to the POTW'since the!stai tup of the system. The second wastewater stream is still being routed to the Biotrol system for treatment and the treated effluent is being discharged to the receiving stream through Outfall 001. , ' =r PART III - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1) Volume of wastewater to be permitted: As per permit application: • Outfall 001 — 0.012 MGD • Outfall 002 — 0.014 MGD 2) What is the_currew permitted -flow limit? • Outfall 001 — 0.2 MGD • Outfall 002 — No flow limit 3) Actual treatment capacity of the current,facility? Discharge Outfall 001 The facility discharges treated process wastewater and boiler blowdown water from the existing wastewater treatment plant through Outfall 001. The wastewater treatment facility consists of three (3) 20,000-gallon holding tanks, bioreactor, clarifier with sludge holding compartment, bag filter system, and two (2) 20,000-post equalization tanks. There does not appear to be any information in the regional office files that identify treatment capacities for any of the listed components. Also, there are no engineering plans and/or specifications in the Regional Office for the wastewater treatment system. , Discharge Outfall 002 The facility discharges non -process contact -cooling water through Outfall 002. This wastewater stream has not required treatment. 4) Date(s)and construction activities allowed_ by previous Authorizations to Construct issued in the previous two years: None 5) Please provide a description of existing or substantially constructed wastewater treatment facilities: The facility has two discharge points, Outfall 001 and Outfall 002. The following is a description of the processes associated with the wastewater discharge for each outfall. Discharge Outfall 001 The facility discharges treated wastewater from the existing wastewater treatment plant through Outfall 001. The wastewater treatment plant receives two wastewater streams, process wastewater and boiler blowdown water. The wastewater treatment plant is comprised of the following components: • Three (3) 20,000 gallon intermediate wastewater holding tanks • One bioreactor (Biotrol) • One combined secondary treatment system, comprised of: • One (1) clarifier • One sludge digestor/sludge holding compartment • Three (3) sock filters • Two (2) 20,000 gallon post -equalization tanks The hexamine plant is the primary source of process wastewater. The process wastewater generated from the hexamine plant is comprised of ammonia, formaldehyde, hexamine, methanol and formic acid. The process wastewater exits the hexamine process and passes through two subsequent product recovery processes, an air stripper unit and a de -ionization (Do system. The process wastewater from the hexamine plant enters the air stripper unit first. A fraction of the ammonia and methanol are removed by the air stripper and recycled back to the hexamine plant. The wastewater then exits the air stripper unit and enters the de -ionization system, which is comprised of a series of three (3) ion exchange units. The De -ionization System removes hexamine and some additional ammonia. The intermediate wastewater exiting the de -ionization system contains predominately formaldehyde and formic acid with trace amounts of methanol, ammonia, and hexamine. The intermediate wastewater is then collected in the three (3) 20,000- gallon intermediate wastewater -holding tanks. The original design of the system allowed for the intermediate wastewater from the wastewater - holding tanks to be directed to several locations for reuse and/or treatment: 1) Wastewater treatment plant (Biotrol); 2) Boilers for use as boiler makeup water;' 3) Formaldehyde plant for recovery or process makeup water 4) De -ionization system for use as backwash; and The .volumes of wastewater sent to each location are not clearly defined in available documentation. The following is a brief discussion of the four streams stated above: a) A portion of the intermediate wastewater from the holding tanks was sent directly to the wastewater treatment plant for treatment and ultimate discharge to the receiving stream via Outfall 001. b) A second portion of the intermediate wastewater is sent to the boilers for use as boiler make- up water. As the wastewater is utilized in the boilers for steam production, a wastewater stream is generated from the steam blowdown, which is collected in a hot well. The hot boiler blowdown water is then passed through a heat exchanger to recover some of the energy. From the heat exchanger, the wastewater is sent to the wastewater treatment plant (Biotrol) for treatment and ultimate discharge to'the receiving stream via Outfall 001. c) The third portion of the intermediate wastewater is sent to the formaldehyde plant for use as process water for blending purposes. d) A fourth portion of the intermediate wastewater is used as filter backwash water.for the de - ionization system. Sulfuric acid is mixed with the wastewater' stream being used for backwash water. The acidified wastewater stream is then passed through each of the three (3) ion exchange units of the de -ionization system in order to regenerate the ion exchange media. The backwash water from the de -ionization system is then routed to the fertilizer production process for reuse. Any backwash water that is not used in the fertilizer process is routed to the lined pond, which is permitted under WQ0000783. Prior to the SOC, two wastewater streams identified above (Items a and b) comprised -the influent wastewater streams routed to the wastewater treatment plant. As specified in the SOC, the facility agreed to eliminate the effluent discharge from Outfall 001 by connection to a Publicly Owned Treatment Works (POTW) operated by Columbus County. The POTW,. located adjacent to the Wright Chemical facility, completed start-up in late July 2006. Wright Chemical began discharging wastewater to the POTW in late July 2006. This ; discharge to the POTW only consists of the wastewater stream that was previously sent directly to the Biotrol system from the intermediate wastewater holding tanks (Item a). Currently, the boiler blowdown wastewater stream continues to be routed to the Biotrol system for treatment and subsequent discharge through Outfall 001 (Item b). Therefore, only one of the influent wastewater streams to the Biotrol system has been eliminated and connected to the POTW. Wright Chemical has not eliminated Outfall 001 as specified in the SOC agreement. Discharge Outfall 002 The facility discharges non -process contact -cooling water from a cooling toNver system through Outfall 002. This wastewater stream has not required treatment in the past. 6) Please provide a_description of proposed wastewater treatment facilities: N/A 7) Possible toxic impacts to surface waters: ammonia, formaldehyde, hexamine, methanol and formic acid 8) Pretreatment Pro ram POTKY only : Not needed 9) Residuals handling and utilization/disposal scheme: Wet sludge disposed of through S&B Maintenance, Inc., Permit No. WQ0000783.

From the history I know, Mark McIntire (who used to work in that Unit) went through a very unpleasant settlement negotiation (they adjudicated their last wastewater permit) to get to that endpoint ... it was pretty messy. Not sure what Bob is doing this time around (and we should coordinate)... but it makes our stormwater permit task even more challenging. What's so difficult about limits on stormwater is that there is no established way to calculate them... the rules specify that 7Q10 conditions (or 30Q2 flow, depending on whether its a carcinogen) are used for ww effluent limits, which are for a continuous discharge. However, there is no set method for calculating WQ-based stormwater limits, and the 7Q10 (low flow) basis doesn't make sense because it will not be a "low flow" condition in a rain event. That's not to say there shouldn't or can't be any in a stormwater permit (and yes, we can make a sound legal argument that we have the authority to impose them), but at the moment we're at a loss for a defensible method to calculate them. You do make a great point with the construction site example, though --that may be helpful here_ There's no doubt that we cannot justify giving them a stormwater permit that essentially permits discharge of wastewater. And that at the numbers we're seeing, we may have an excellent argument that stormwater must in fact be contacting enough raw material to be considered a process wastewater --which means it's not stormwater. need to sit down with Bradley and discuss some approaches, especially in light of Matt's thoughts on the toxicity testing. I'll let you know what he says. -BG Bethany Georgoulias Environmental Engineer NC DENR DWQ Stormwater Permitting Unit (919) 733-5083, ext. 529 bethany.georgouliasoncmail.net Linda Willis wrote: Bethany Georgoulias wrote: Linda, Yes, I got directions on where to meet all of you --Sarah Young and I will meet 1 of 6 1/30/2006 10:36 ANI !Fwd: Re: Wright] 1p- • you there at 10:30.

We have the authority to do that, we just need to choose our strategy. We can even issue the permit for a shorter period of time than 5 years, but again, we need to have a good idea of what would be next, particilarly if there is any legal challenge in the future. Bradley even suggested working with NPDES wastewater on this one, and in fact, that permit may be up for renewal shortly, too. I'm hesitant about requiring instream monitoring in the stormwater permit if the wastewater discharge introduces influence because the data could be difficult to use ... but then again, if they're complying with the wastewater limits, their ww shouldn't violate water quality standards in a worst case low flow condition, and therefore not in a rain event that increases stream flow --so it might still be worthwhile; it just may be more of a safety issue at times for their employees in storm conditions. No, I haven't seen any information granting their representative outfall status .(but I'll comb the files again), and I intend to ask the contact if they've submitted that info. per your request.

The WWTP outfall and stormwater outfalis goes to a swampy area that 2 of 6 1/30/2006 10:36 AN }` [Pwd: Re`: Wright] interconnects both Livingston Creek and Mill Creek. The upstream downstream sampling would have the influence of all wastest reams from the site (NPDES WW discharge and stormwater outfall discharges). Livingston has the influence from IP as well. Upstream/Downstream sampling could be required in the stormwater permit can't it?? For let's say BOD, COD, NH3-N, and TKN along with DO, Conductivity and PH. The last permit cycle (permit issued Feb, 2000) there was no mention of representative outfall status granted or acknowledged in the text of that permit. Correct me if we have granted them that. In my last inspection report I asked for the data showing supporting evidence that outfalls 1, 4, 6 and 7 were granted represent. outfall status. I did not receive anything from Wright. Can you all look through your records to see if that was granted? Here's what we'd like to see (I visited a little bit with Ed Beck on this). - Ed did say that since this is an individual permit, we should be able to modify it anyway we deem appropriate and effective to fit the situation at Wright. 1.) Require all outfalls be monitored fully including BOD, COD, NH3-N, TSS, TKN, TP, pH , formaldehyde, hexamine, (lead had a hit above cut off levels in 2002) not sure if you want that one to stay in. We need to know what the situation is at all the outfalls (let's hope they are not representative because that would truly be bad for all the outfalls to be so heavily contaminated) and I think if some of those outfalls had been given "representative outfall status" that needs to be eliminated. Also I recommend toxicity testing for each outfall once per year (to get a baseline). . if they pass "X" (not sure what is reasonable for "X") number of sampling events in a row, they can be given the flexibiilty of not testing again until the last year of the permit (perhaps). Maybe in lieu of toxicity at the outfalls, we have them do upstream/downstream monitoring for every parameter on their NPDES WW Permit (NC0003395) including COD. 2.) This is the second permit round that we will (most likely) see the stormwater from the site bust cut off concentrations. Housekeeping has been addressed in their BMP's yet they admit housekeeping remains a problem which they cannot seem to find solutions for (hexamine storage area for example). Our language in the new permit should keep cutoff concentrations as a benchmark that if exceedances continue. . the Division will be looking for action from Wright to resolve in an expedient manner. . give them a time schedule to address the problem once the cutoff concentration has been exceeded. Require them to write a report to us telling us why the contaminants were so high and what they are doing to resolve the issue. If tightening up on housekeeping works, fine. If not, we should require that Wright capture the on site run off (in those areas feeding the outfalls that are above cut off concentrations) and treat it as a wastewater. Let's keep in mind, their BOD loading to the receiving stream from stormwater runoff (if you crunch some numbers) arc a magnitude of 10 to 80 times higher than their NPDES WW BOD limits! Industrial sites are tough, we have a few throughout our region. Many of those capture their stormwater in their processing and storage areas and treat it onsite as a wastewater. Granted, they probably use it for dilution of their process wastewater and therefore happy to run it through their WWTPs. None the less, it does not leave the site with stormwater. Wright may have to consider their stormwater a wastewater that should be treated if they cannot resolve these issues_ Thanks for the update Bethany. We are all ears here and look forward to working with you all on this one. Perhaps you all would like to go visit the site? 3 of 6 1/30/2006 I0:36 AN [Fwd: Re: Wrigbt] Best Regards, Linda Willis Bethany, Did you get up with layton as to where we all would meet you up there in Morehead for the Port inspection?? The ports have'a security guard at a little check point when entering, we could meet there (just a suggestion) Let me know, we can all wait at the same place. Did Layton have any problems with the list of individuals that would be inspecting the facility and did he have any problems with the State personnel having a camera with them?? Comments on Wright Corporation Look at NC General Statute 143-215.1(a)(4), (6) and (al). . . No person shall do any of the following. (4) increase the quantity of waste *discharged through any outlet* or processed in any treatment works or disposal system to any extent that would result in any violation* *of the* eflfuent standards or *limitations established for any point source* *or that would adversely affect the condition of the receiving waters to the extent of violating any applicable standard . * (al) *in the event that both effluent standards or limitations and classifications and water quality standards are appicable to any point source or sources and to the waters to which they discharge, the more stringent among the standards established by the commis shall be applicable and controlling. *This says to me that we can impose effluent standard limitations on the stormwater discharge no less stringent, that that of their NPDES Individual permit since their are no water quality standards for ammonia or BOD but their are effluent standards for that receiving stream from this facility from a point source.* Looking at 143-215. *The Commission is authorized and directed to develop, adopt, modify and revoke effluent standards or limitation* and waste treatment management practices *as it determines necessary to. prohibit abate or control water pollution*. *The effluent standards or limitations developed.and adopted by the commission shall provide limitations upon the effluents dishcarged from* pretreatment facilitites* and from outlets and point sources to the water of the state adequate to limit the waste loads upon the waters of the State to the extent necessary to maintain or enhance* the blah blah blah We can, should and are directed to impose limits, not just cut off concentrations. . . Looking at this Bethany, why can we not put limits in their NPDES Stormwater Individual Permit to accomplish what we are directed here to do. We limit their wastewater effluent for BOD, and NH3 as N at levels far below that 4 of 6 1/30/2006 10:36 Ail ' [Fwd:'Re. Wright] S discharged with their stormwater. We have the power to put limits f (enforceable) in their stormwater permit as stated above don't we??? If their WW permit deems NH3--N and BOD levels as applicable standards for their -discharge, how can those levels not be "applicable" to their stormwater discharge?? They must be sure their stormwater effluent is no more polluted than the effluent limits given them for their treated process wastewater. If they cannot prevent contaminants from being in contact with the stormwater, they should have to treat: that as a wastestream_ It has all the characterisitics of a wastewater not just what we typically see as stormwater runoff. The reps above state our ability to do this. I believe we need to put BOD and NH3-N limits no less stringent than what is in their NPDES WW permit . We have a construction site here in town that is contaminated with urea. When in contact with stormwater,-the runoff becomes a fairly concentrated wastewater of ammonia. . to the tune of 50 ppm to 40000 ppm. We issued two NOV's for discharging ammonia to the stormdrains. Although we had no stream standard limits for ammonia, it is a constituent that has limits on NPDES discharge permits and in the tune of 2 and 4 ppm (depending upon season). on that premise we stated that no ammonia taxi leave their site via stormwater runoff or stormdrains to surface waters in concentrations greater than that. Wright's situation is no different. The cited facility brought in an on site WW treatment system to treat the ammonia below 50 ppm in order to send it to the City of Wton's WWTP, not until they get below concentrations of 2 and 4 are we able to allow them to let it "runoff" to the river. Water quality standards only address a specific list of contaminants or conditions. . it doesn't encompass everything. The regs allow us though to impose beyond water quality standards (which misses a lot of stuff) by allowing us to use either effluent limitations that would be applicable for a discharge, or the water quality standard or when both come into play, the more stringent of the two. As I see it, we must force the issue of adherence to no more than 2 and-5 monthly limits and 10 and 25 daily max's (right in line with their effluent permit) which goes to the same receiving stream_ We cannot be any less stringent on this source of contamination (even though stormwater related) than that issued for the point source effluent WW discharge_ Same goes for BOD. Well that's my argument for this situation. Perhaps I'm missing something but, I think we have two legs to stand on concerning this particular site and it's obvious stormwater contamination problems. I look forward to your response. Linda Willis I already sent a list to him, so he's good to go. . . Tom Moore may come along, I told Tom I:d have to put him on the list so he'll have to give me an answer by tomorrow at least. By the way, I was wrong, Wright has BOD mass limits (12.8 and 34 lbs) monthly/daily respectively. . but not NR3 limits_ . they have a really relaxed permit (NPDES Individual) since that's coming up for renewal, let's talk about their NPDES Permit renewal limits too.

The samples of concern were given the following lab numbers: MW-6 is AB14767; MW-7 is AB1476B; MW-9 is AB14769. The sample bottles marked as preserved with sulfuric acid and for analysis of NH3, TKN, NO3NO2, and TP were checked with pH strips to verify that sample pH was <2 (as we do for all samples that we receive). The sample pH of these three samples was 6 to 7. We also checked the bottles marked for NO3 (no acid preservation) and they were at pH of 7. We checked the bottles for wet Chem, and those were okay, too (no acid). So it appears that either you forgot to add the acid to these bottles, or you did add the acid and the sample pH did not hold at <2 during transport. In the lab, I added 2 ml of 25% sulfuric acid to these bottles to adjust sample pH to <2. I noticed that each sample appeared to react with the sulfuric acid more than is normal, and the samples had a strong odor of sulfide. Sample AB14768 required 3 ml of 25W sulfuric acid to adjust sample pH to <2, and reacted strongly to the acid (alot of bubble formation and the sample bottle even began to slightly bulge before I removed the cap to relieve the pressure). Anyway, we will proceed with the analyses, but the results for NH3, TKN, NO3NO2, and TP will be qualified with J6 due to sample pH not being <2. Note that the acid -preserved samples for the other four sites that you collected on 3/20/07 had sample pH <2. If you have any questions, you can reach me at 919-733-3908, extension 227.
