Section I - INTRODUCTION
Anthony Timberlands/ Malvern Permit # ARR00B476
Inspection Date 03/08/2023
PURPOSE OF THE INSPECTION
United States Environmental Protection Agency (EPA) Region 6 inspectors David Esparza, PE, and Ms. Chelsey Sherwood, arrived at Anthony Timberlands-Malvern facility (Malvern) at approximately 9:00 AM on March 8, 2023, for an unannounced inspection. I presented my credentials to Mr. Jim Jones, Vice President-Pine Division, of Anthony Timberlands, Inc. I informed him that this was an EPA inspection to determine the facility's compliance under the Clean Water Act (CWA) and the requirements of the National Pollutant Discharge Elimination System (NPDES) permit program, in accordance with the CWA. The generation of this report is based on information supplied by Malvern representatives, observations made by the EPA inspectors, and records and reports maintained by the permittee (Malvern), and the EPA. Before leaving the facility on March 8, 2023, an exit briefing was held with Mr. Jones and Mr. Wilson Anthony, Director of Regulatory Compliance (via telephone conference), to explain areas of concern noted at the time of the inspection.
FACILITY DESCRIPTION
Anthony Timberlands, Inc. (ATI) acquired the Hot Spring County Lumber Company and its landholdings in Malvern (Hot Spring County) in 1974. Approximately 2-years later, ATI acquired the Hollicer-Jones Lumber Company in Benton (Saline County) along with its land holdings and consolidated its mill into the Malvern site circa 1980. With production expanded this pure pine operation has a capacity of approximately 120 million board feet per year. The approximate 63-acre mill site is in the near proximity to 930 Cabe Avenue adjacent to the Union Pacific railroad and East of United States Interstate-30 (I-30) in Malvern, Hot Spring County, Arkansas (denoted in Aerial Image 1 below). Coordinates to the mill located along the edge of the Ouachita Mountains/Ouachita National Forest are in the vicinity of: Latitude 3421'52.31" North, Longitude 9249'16.60" West. The mill operates the sawmill and planing mill Monday through Friday 6:00 AM to 3:00 PM on a two (2) shift schedule, though certain mill processes (kiln drying, boiler operation) are performed around the clock.

Aerial Image #1- Overall view of the Anthony Timberlands-Malvern facility. Aerial from Google Earth (September 2021). Section II - OBSERVATIONS The following points of discussion are derived from review of the information provided by Anthony Timberlands representatives, their consultant, or on-site visual observation. The entire electronic version of the Stormwater Pollution Prevention Plan (SWPPP) was reviewed, inclusive of inspection reports, waste manifests and site plans/maps.
A Notice of Intent (NOI) (ARR00B476) was issued by the Arkansas Energy and Environment, Division of Environmental Quality, Office of Water Quality with an effective date of July 1, 2019, and the subsequent expiration date of June 30, 2024.
An electronic copy of the Stormwater Pollution Prevention Plan (SWPPP), originally adopted in October 1993 and revised in December 2022 and again in March 2023 was reviewed. Note: the SWPPP cover photograph taken on-site March 8, 2023, differs from the electronic version cover submitted pursuant to the Request for Information (RFI) (Appendix 1 Photograph #1 and Appendix 4).
The SWPP indicates inspections related to Outfall 001 were performed in March 2017 through August 2022.
An ADEQ letter dated January 12, 2023, authorized discharges from two (2) additional outfalls: Outfall 002 and Outfall 003.
The SWPPP states, security is third party contracted, though overall security is poor, due in part to its location and the presence of a former city street which traverses the site.

Anthony Timberlands/ Malvern Permit # ARR00B476
Inspection Date 03/08/2023
A city (Malvern) stormwater conduit, upgradient and Southeast discharges into the facility along Cabe Avenue and contributes large volumes of water to the ditches that lead to Outfall 002 and Outfall 003.
A bulk fuel facility (Ligon Oil) comprised of approximately 4-10K aboveground storage tanks (ASTs) upgradient and adjacent to the Malvern stormwater conduit did not have spill containment in-place.
Visible sheen at land surface was observed at various locations within the facility indicative of "abandoned" equipment hydraulic lines, bulk oil drums, etc. have not been adequately drained/purged (Appendix 1 Photograph #2, Photograph #3, Photograph #4, Photograph #5, Photograph #6 and Photograph #7).
A review of the information provided by ATI in their written response to a March 14, 2023, Request for Information (RFI), indicates the facility maintains on-site 1-100-gallon, 2-350-gallon, 2-550-gallon, 2-1K-gallon, and 1-12.5K-gallon bulk petroleum storage tanks. Note: observation indicated the facility had recently completed some concrete containment berms around the various ASTs though, those with containment needed pumping and/or cleaning. Additionally, it was not clear if the capacity of the containments accounted for precipitation (Appendix 1 Photograph #8, Photograph #9, Photograph #10, Photograph #11, Photograph #12, Photograph #13, and Photograph #14).
Housekeeping, inclusive of staged debris (equipment, motor vehicles, replaced parts, tires, drums, wooden pallets, etc.) throughout the facility invite vermin attraction (Appendix 1 Photograph #15, Photograph #16, Photograph #17 and Photograph #18).
The stormwater wattles installed/placed throughout various locations of the facility were irregularly spaced, small in diameter and not staked in typical industry methodology (Appendix 1 Photograph #12, Photograph #19 and Photograph #20).
A review of the 2021/2022 Stormwater Annual Report (SWAR) analytical results indicates, an excursion of the benchmark value for Chemical Oxygen Demand (COD) occurred. (Appendix 5)
Debris consistent with wastewater sanitary sewer overflow (SSO) events was visible at several locations (Appendix 1 Photograph #21 and Photograph #22).
Review of the Waste Manifest documents provided by ATI in their written response to a March 14, 2023, Request for Information (RFI), indicates the non-aqueous constituents of "soil, wood chips and debris with hydraulic oil" and aqueous constituents of "creek water with hydraulic oil", though the analytical amounts are not defined (Appendix 6).
A review of the facility Remediation and Maintenance Plan prepared by ECCI on behalf of ATI identified the primary Constituents of Concern (COC) as oil and grease (O&G). Additional COCs include Resource Conservation Recovery Act (RCRA) 8 Metals, Chemical Oxygen Demand (COD), and dissolved oxygen (DO). The proposed Remediation and Maintenance Plan was approved by ADEQ on January 17, 2023 (Appendix 7).
Section III - SUMMARY/AREAS OF CONCERN (AOC)
The entire evaluation can be summarized as follows:
The SWPP states, security is third party contracted, though overall security is poor, due in part to its location and the presence of a former city street which traverses the site. This deficiency allows unauthorized ingress and egress and potentially exacerbates vandalism and/or thief.
Though under other ownership a bulk fuel facility (Ligon Oil) comprised of approximately 4-10K aboveground storage tanks (ASTs) upgradient and adjacent to the Malvern stormwater conduit did not have spill containment in-place to prevent "run-on" into the Facility. This aspect can be

identified under Part: 3 Best Management Practices, Limitation and Monitoring RequirementsSubparts 3.1: Best Management Practices, 3.1.1: Minimize Exposure, 3.1.3: Maintenance, 3.1.4: Spill Prevention and Response Procedures. The stormwater wattles installed/placed throughout various locations of the facility were irregularly spaced, small in diameter and not staked/anchored in typical industry methodology. This could negate the purpose of these devices in the prevention or efforts to minimize run-off (Appendix 1 Photograph #12, Photograph #19 and Photograph #20). Visible sheen at land surface was observed at various locations within the Facility indicative of "abandoned" equipment hydraulic lines, bulk oil drums, etc. not adequately drained/purged. The following NPDES sections were lacking or deficient; Part: 3 Best Management Practices, Limitation and Monitoring Requirements- Subparts 3.1: Best Management Practices, 3.1.1: Minimize Exposure, 3.1.2: Good Housekeeping, 3.1.3: Maintenance, 3.1.4: Spill Prevention and Response Procedures, 3.1.6: Management of Runoff, 3.1.10, Part 4: Stormwater Pollution Prevention Plan (SWPPP) - Subparts 4.2.3: Facility Description, 4.2.4: Description of Potential Pollutant Sources, 4.2.6: Schedules and Procedures (4.2.6.1.1, 4.2.6.1.2 and 4.2.6.1.3) (Appendix 1 Photograph #2, Photograph #3, Photograph#4, Photograph #5, Photograph #6 and Photograph #7). Review of the Waste Manifest documents provided by ATI in their written response to a March 14, 2023, Request for Information (RFI), indicates the non-aqueous constituents of "soil, wood chips and debris with hydraulic oil" and aqueous constituents of "creek water with hydraulic oil", though the analytical amounts are not defined (Appendix 6). This constituent documentation leads to the potential of "run-off" impacts downstream. A review of the 2021/2022 Stormwater Annual Report (SWAR) analytical results indicates, an excursion of the benchmark value for Chemical Oxygen Demand (COD) occurred (Appendix 5). Debris consistent with wastewater sanitary sewer overflow (SSO) events was visible at several locations along various Facility perimeter locations. Part: 3 Best Management Practices, Limitation and Monitoring Requirements- Subparts 3.1: Best Management Practices, 3.1.1: Minimize Exposure (Appendix 1 Photograph #21 and Photograph #22). Poor housekeeping, inclusive of staged debris (equipment, motor vehicles, replaced parts, drums, wooden pallets, tires, etc.) throughout the facility are an invitation to vermin attraction. The following NPDES sections were lacking or deficient; Part: 3 Best Management Practices, Limitation and Monitoring Requirements- Subparts 3.1: Best Management Practices, 3.1.1: Minimize Exposure, 3.1.2: Good Housekeeping, 3.1.3: Maintenance, 3.1.4: Spill Prevention and Response Procedures, 3.1.6: Management of Runoff, 3.1.10: Waste, Garbage and Floatable Debris(Appendix 1 Photograph #16, Photograph #17 and Photograph #18). Review of the electronic copy of the Stormwater Pollution Prevention Plan (SWPPP), originally adopted in October 1993 and revised in December 2022 and again in March 2023 was reviewed. The following NPDES sections were lacking or deficient; Part 4: Stormwater Pollution Prevention Plan (SWPPP)- Subparts 4.2.3: Facility Description, 4.2.4: Description of Potential Pollutant Sources, 4.2.6: Schedules and Procedures (4.2.6.1.1, 4.2.6.1.2 and 4.2.6.1.3).

Information (RFI), indicates the Facility maintains on-site 1-100-gallon, 2-350-gallon, 2-550gallon, 2-1K-gallon, and 1-12.5K-gallon bulk petroleum storage tanks (16.6K Total). Note: observation indicated the facility had recently completed some concrete containment berms around the various ASTs though, those with containment needed pumping and/or cleaning. In accordance with 311 of the Clean Water Act (CWA) (https://www.epa.gov/oil-spills-preventionand-preparedness-regulations) and the SPCC Rule (40 CFR 112), a SPCC plan is required (Appendix 3 Request for Information (RFI) Response).
EPA Region 6 inspector David Esparza conducted a closing conference at Anthony Timberlands-Malvern facility on March 8, 2023, for the inspection.
Section IV - FOLLOW UP
The following information was received by EPA on March 16, 2023, in an ATI "redline" explanation to the March 14, 2023, Request for Information (RFI) after exiting the Facility on March 8, 2023:
A complete electronic copy of your current Stormwater Pollution Prevention Plan (SWPPP), inclusive of all on-site inspection reports for the previous two (2) years. Reply: See attached "Stormwater Pollution Prevention Plan - March 2023" and "Quarterly and Annual Stormwater Inspections"
A legible electronic copy of your "Exhibit A" (Redline Plan Sheet #D502001E). Reply: See "Malvern Exhibit A" and "Malvern - Exhibit A Explanation"
A current copy of the facility Site Map delineating the total foot-print area, locations/volumes of the onsite fuel storage tanks, and outfalls. Reply: See "Malvern Site Map with Total Site Area." When combined with "Malvern Exhibit A," I believe that the total area, locations/volumes of petroleum storage tanks, and outfalls are all covered. An electronic copy of your Spill Prevention, Control, and Countermeasure (SPCC) pertaining to your on-site fuel storage. Reply: The facility is currently in the process of installing additional secondary containments in a couple of areas. The facility hopes to have these complete along with our SPCC within the next 60 days.
Electronic copies of your waste manifests for your on-site oil/water separator regarding the transport/disposal for the previous two (2) years. Reply: I have attached these in a few separate emails due to the file size. We have had a large number of waste manifests. Only a small amount is related to the oil/water separator, but that material is not differentiated in the manifests since it has the same profile as our other disposals.
Electronic copies of your Stormwater Annual Report (SWAR) for the previous two (2) years, inclusive appurtenant analytical analysis. Reply: See attached "2021 and 2022 SWAR"
Electronic copies of your calibration and maintenance records for your continuous monitoring instrumentation, inclusive of serial numbers (S/N). Reply: The facility does not have any continuous monitoring instrumentation.

Page 7 Part 1 Permit Number ARR000000
1.6 Allowable Non-stormwater Discharges. The following non-stormwater discharges are authorized by this permit:
1.6.1 1.6.2 1.6.3 1.6.4 1.6.5
1.6.6 1.6.7
1.6.8 1.6.9 1.6.10
1.6.11
1.6.12 1.6.13
1.6.14 1.6.15
discharges from emergency firefighting activities; fire hydrant flushings; potable water sources including waterline flushings; runoff from irrigation using non-process water; landscape watering provided all pesticides, herbicides, and fertilizers have been applied in accordance with the approved labeling; uncontaminated routine external building washdown which does not use detergents; uncontaminated pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used; air compressor condensate; steam condensate; uncontaminated condensate from air conditioners, coolers, and other compressors and from the outside storage of refrigerated gases or liquids (such as the discharge of thawed condensate from the surface of liquid nitrogen tanks stored outdoors); incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of the facility, but not intentional discharges from the cooling tower (e.g., "piped" cooling tower blowdown or drains); uncontaminated ground water or spring water (See Note Below); foundation or footing drains where flows are not contaminated with process materials such as solvents, or other toxic or hazardous material (see Note below); excavation dewatering (see Note below and the definition in Part 8.11); and non-process water used for dust suppression on uncontaminated roads.
NOTE: There shall be no turbid discharges to surface waters of the state resulting from dewatering activities. If trench or ground waters contain sediment, it must pass through a sediment settling pond or other equally effective sediment control device, prior to being discharged. Alternatively, sediment may be removed by settling in place or by dewatering into a sump pit, filter bag, or comparable practice. Ground water dewatering which does not contain sediment or other pollutants is not required to be treated prior to discharge. However, care must be taken when discharging ground water to ensure that it does not become pollutant-laden by traversing over disturbed soils or other pollutant sources.
1.7 Conditional No Exposure Exclusion. In accordance with 40 CFR 122.26(g), a No Exposure Exclusion is a conditional exclusion applicable to all categories of industrial activity (except construction activity) with no exposure of industrial materials and activities to stormwater. All facilities with point source discharges composed entirely of stormwater associated with industrial activity that satisfy criteria of no exposure and complete the No Exposure Exclusion Certification Form will be able to obtain exclusion from this general permit. The Exclusion is available on a facility-wide basis only, not for individual outfalls. If any industrial activities or materials are or will be exposed to precipitation, the facility is not eligible for the No Exposure Exclusion. To apply for a No Exposure Exclusion, a complete and accurate No Exposure Exclusion Certification Form and an initial permit fee as required under the provisions of Reg. 9 should be submitted. Subsequent annual fees will be billed by the Department. Facilities operating under a 2014 Industrial Stormwater General Permit No Exposure Exclusion must submit a Recertification NOI under Part 2.2, assuming the facility still qualifies for the exclusion.
1.8 Limitations on Coverage (Exclusions). The following stormwater discharges associated with industrial activity are not covered by this permit:
1.8.1 Discharges Mixed with Non-Stormwater. Stormwater discharges associated with industrial activity that are mixed with sources of non-stormwater, except for non-stormwater discharges that are identified by and in compliance with Part 1.6 of the permit.
Page 8 Part 1 Permit Number ARR000000
1.8.2 Stormwater Discharges Associated with Construction Activity. Stormwater discharges associated with construction activity disturbing one acre or more are not eligible for coverage under this permit, even if a permittee currently has coverage under this permit.
1.8.3
Discharges Currently Covered by Another Permit. A facility is not eligible for coverage under this permit unless stormwater requirements from the individual permit can be transferred to this general permit. In order to avoid conflict with the "anti-backsliding" provisions of the Clean Water Act (CWA), a permit transfer will only be allowed where the outfall in the individual permit did not contain numeric water quality-based limitations with an exception of pH. A pH range limit would not necessarily be considered a water-quality based limit unless developed to address known discharge problems at a particular facility. Compliance with the numeric limitations under the individual permit could also be criteria for eligibility to transfer from an individual permit to the general permit.
1.8.4 Discharges Subject to Effluent Guidelines. Stormwater discharges associated with industrial activity from facilities which are subject to existing effluent guideline limitations addressing stormwater with the exception of those listed in Part 1.4.3.
1.8.5 Discharges into Impaired Receiving Waters (303(d) List). Discharges from a facility into receiving waters listed as impaired under Section 303(d) of the Clean Water Act are not eligible for coverage under this permit, unless the permittee:
1.8.5.1 1.8.5.2
documents that the pollutant(s) for which the waterbody is impaired is not present in the facility's stormwater discharge(s) and retain documentation of the finding with the SWPPP; or incorporate into the SWPPP any additional BMPs needed: 1.8.5.2.1 to prevent to the maximum extent practicable exposure of pollutants to stormwater for
which the waterbody is impaired; and 1.8.5.2.2 to sufficiently protect water quality.
Please note that the Department will review this information. If it is determined that the facility will discharge to an impaired water body, then the Department may include additional requirements.
1.8.6 Discharges into Receiving Waters with an Approved TMDL. Discharges from a facility into receiving waters for which there is an established Total Maximum Daily Load (TMDL) allocation are not eligible for coverage under this permit unless:
1.8.6.1 the permittee develops and certifies a SWPPP that is consistent with the assumptions and requirements in the approved TMDL; and
1.8.6.2 if a specific numeric wasteload allocation has been established that would apply to the facility's discharges, the operator must incorporate that allocation into its SWPPP and implement necessary steps to meet that allocation.
Please note that the Department will be reviewing this information. If it is determined that the facility will discharge to receiving waters with an approved TMDL, then the Department may require additional BMPs.
1.8.7 Direct Discharges into an Extraordinary Resource Water (ERW), Natural and Scenic Waterway (NSW), or Ecologically Sensitive Waterbody (ESW). Discharges from a facility directly into receiving waters which are listed as an ERW, NSW, or ESW under the authority of Reg. 2 are not eligible for coverage under this permit unless:
1.8.7.1 the permittee develops and certifies a SWPPP that includes additional BMPs needed to prevent to the maximum extent practicable exposure of pollutants to stormwater that could potentially impact water quality.
Page 9 Part 1 Permit Number ARR000000
Please note that the Department will review this information. If it is determined that the facility will discharge to an ERW, NSW, or ESW, then the Department may require additional BMPs.
1.8.8 Discharges that the Department has determined will cause impairment or has reason to believe will compromise Water Quality Standards. Discharges from a facility into receiving waters which the Department has determined will cause an impairment, or has reason to believe will compromise Water Quality Standards, are not eligible for coverage under this permit unless:
1.8.8.1 the permittee develops and certifies a SWPPP that includes additional BMPs needed to prevent to the maximum extent practicable exposure of pollutants to stormwater that could potentially impact water quality.
Please note that the Department will review this information. If it is determined that the facility will cause an impairment, or will compromise Water Quality Standards, then the Department may require additional requirements.
1.8.9 Discharges containing polychlorinated biphenyls (PCBs). Discharges of stormwater known to contain PCBs are not eligible for coverage under this permit. Stormwater discharges containing PCBs must be covered under a separate NPDES permit, discharged to a sanitary sewer in accordance with applicable industrial pretreatment requirements, or disposed of otherwise in accordance with applicable law.

Page 13 Part 3
Permit Number ARR000000
PART 3: BEST MANAGEMENT PRACTICES, LIMITATIONS AND MONITORING REQUIREMENTS
3.1. Best Management Practices. All facilities must comply with the following BMPs. Parts 3.1.1 through 3.1.11 are considered part of every facility's SWPPP unless the permittee has incorporated into the SWPPP adequate justification or data indicating why the BMP does not apply to the facility or the facility's stormwater discharges. BMPs are primarily to be used by the facility as the factors to consider when attempting to prevent pollutants from leaving the facility via stormwater exposed to industrial activities.
3.1.1.
Minimize Exposure. The operator must take actions as appropriate to minimize the exposure of potential sources of pollutants in the manufacturing, processing, and material storage areas (including loading and unloading, storage, disposal, cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff by either locating these industrial materials and activities inside or protecting them with storm resistant coverings (although significant enlargement of impervious surface area is not recommended). In minimizing exposure, the operator should pay particular attention to the following:
use grading, berms, or curbing to prevent runoff of contaminated flows and divert run-on away from these areas;
locate materials, equipment, and activities so that leaks are contained in existing containment and diversion systems (confine the storage of leaky or leak-prone vehicles and equipment awaiting maintenance to protected areas);
clean up spills and leaks promptly using dry methods (e.g., absorbents) to prevent the discharge of pollutants;
use drip pans and absorbents under or around leaky vehicles and equipment or store indoors where feasible;
use spill/overflow protection equipment; drain fluids from equipment and vehicles prior to on-site storage or disposal; perform all cleaning operations indoors, under cover, or in bermed areas that prevent runoff and run-on
and also that capture any overspray; and ensure that all washwater drains to a proper collection system (i.e., not the stormwater drainage system).
The discharge of vehicle and equipment washwater, including tank cleaning operations, is not authorized by this permit. These wastewaters must be covered under a separate NPDES permit, discharged to a sanitary sewer in accordance with applicable industrial pretreatment requirements, or disposed of otherwise in accordance with applicable law.
Note: Industrial materials do not need to be enclosed or covered if stormwater runoff from affected areas will not be discharged to receiving waters or if discharges are authorized under another NPDES permit.
3.1.2. Good Housekeeping. The operator must incorporate good housekeeping practices in an effort to keep clean all exposed areas that are potential sources of pollutants, using measures including, but not limited to, sweeping at regular intervals, keeping materials orderly and labeled, and storing materials in appropriate containers.
3.1.3.
Maintenance. The operator must regularly inspect, test, maintain, and repair all industrial equipment and systems to avoid situations that may result in leaks, spills, and other releases of pollutants in stormwater discharged to receiving waters. The operator must maintain all control measures that are used in the implementation of the Best Management Practices or to achieve the effluent limits required by this permit in effective operating condition. Nonstructural control measures must also be diligently maintained (e.g., spill response supplies available, personnel appropriately trained). If the operator finds that the control measures need to be replaced or repaired, the operator must make the necessary repairs or modifications as expeditiously as practicable.

Permit Number ARR000000
3.1.4. Spill Prevention and Response Procedures. The operator must minimize the potential for leaks, spills and other releases that may be exposed to stormwater and develop plans for effective response to such spills if or when they occur. At a minimum, the operator must implement:
Procedures for plainly labeling containers (e.g., "Used Oil," "Spent Solvents," "Fertilizers and Pesticides," etc.) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur;
Preventative measures such as barriers between material storage and traffic areas, secondary containment provisions, and procedures for material storage and handling;
Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other releases. Employees who may cause, detect, or respond to a spill or leak must be trained in these procedures and have necessary spill response equipment available. If possible, one of these individuals should be a member of the stormwater pollution prevention team (see Part 4.2.2); and
Procedures for notification of appropriate facility personnel, emergency response agencies, and regulatory agencies. Where a leak, spill, or other release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, or 40 CFR Part 302, occurs during a 24-hour period, the operator must notify the National Response Center (NRC) at (800) 424-8802 in accordance with the requirements of 40 CFR Part 110, 40 CFR Part 117, and 40 CFR Part 302 as soon as the operator has knowledge of the discharge. Local requirements may necessitate reporting spills or discharges to local emergency response, public health, or drinking water supply agencies. Contact information must be in locations that are readily accessible and available.
3.1.5.Erosion and Sediment Controls. The operator must stabilize exposed areas and control runoff using structural or non-structural control measures to minimize onsite erosion and sedimentation, and the resulting discharge of pollutants. Among other actions the operator must take to meet this limit, the operator must place flow velocity dissipation devices at discharge locations and within outfall channels where necessary to reduce erosion or settle out pollutants. In selecting, designing, installing, and implementing appropriate control measures, the operator is encouraged to consult with EPA's web-based resources relating to BMPs for erosion and sedimentation, including the sector-specific Industrial Stormwater Fact Sheet Series (https://www.epa.gov/npdes/industrial-stormwater-fact-sheet-series), National Menu of Best Management Practices (BMPs) for Stormwater (https://www.epa.gov/npdes/national-menu-best-management-practicesbmps-stormwater#edu), and Urban Runoff: National Management Measures (https://www.epa.gov/nps/urban-runoff-national-management-measures), and any similar publications.
3.1.6.
Management of Runoff. The operator must implement appropriate measures to manage the runoff from the property in such a manner as to minimize the pollutants in the discharge. These measures may include, but are not limited to, the diversion of the runoff away from areas where pollutants may be present or the reuse of stormwater runoff where practicable, by the use of measures that divert the runoff, contain the runoff, or allow for reuse of the runoff. In selecting, designing, installing, and implementing appropriate control measures, the operator is encouraged to consult with EPA's web-based resources relating to runoff management, including the sector-specific Industrial Stormwater Fact Sheet Series (https://www.epa.gov/npdes/industrial-stormwater-fact-sheet-series), National Menu of Best Management Practices (BMPs) for Stormwater (https://www.epa.gov/npdes/national-menu-best-management-practicesbmps-stormwater#edu), and Urban Runoff: National Management Measures (https://www.epa.gov/nps/urban-runoff-national-management-measures), and any similar publications.
3.1.7.
Salt Storage Piles or Piles Containing Salt. The operator must enclose or cover storage piles of salt, or piles containing salt, used for deicing or other commercial or industrial purposes, including maintenance of paved surfaces. The operator must implement appropriate measures (e.g., good housekeeping, diversions, containment) to minimize exposure resulting from adding to or removing materials from the pile. Piles do not need to be enclosed or covered if stormwater runoff from the piles is not discharged or if discharges from the piles are authorized under another NPDES permit.
Page 15 Part 3
Permit Number ARR000000
3.1.8.
Employee Training. The operator must train all employees who work in areas where industrial materials or activities are exposed to stormwater, or who are responsible for implementing activities necessary to meet the conditions of this permit (e.g., inspectors, maintenance personnel), including all members of the Pollution Prevention Team. Training for employees whose job duties include implementation of pollution prevention measures or Stormwater Pollution Prevention Team members must cover both the specific control measures used in the implementation of the BMPs in this Part, and monitoring, inspection, planning, reporting, and documentation requirements in other parts of this permit. Training for employees who work in areas where industrial materials or activities are exposed to stormwater, but whose job duties do not include implementation of pollution prevention measures should cover the specific control measures and BMPs used in the facility area in which they work. The Department recommends training be conducted at least annually (or more often if employee turnover is high).
3.1.9. Non-Stormwater Discharges. The operator must eliminate non-stormwater discharges not authorized by an NPDES permit. See Part 1.6 for a list of non-stormwater discharges authorized by this permit.
3.1.10. Waste, Garbage and Floatable Debris. The operator must take actions as appropriate to ensure that waste, garbage, and floatable debris are not discharged to receiving waters by keeping exposed areas free of such materials or by intercepting them before they are discharged.
3.1.11. Dust Generation and Vehicle Tracking of Industrial Materials. The operator must take actions as appropriate to minimize generation of dust and off-site tracking of raw, final, or waste materials.
3.2. Water Quality Standards. Any discharge of stormwater associated with industrial activity must be controlled as necessary to meet applicable water quality standards. New discharges or increased loadings from existing discharges must be consistent with the Arkansas Anti-Degradation Policy in Reg. 2. The Department expects that compliance with the other conditions in this permit will control discharges as necessary to meet applicable water quality standards. If at any time the facility becomes aware, or the Department determines, that the facility's discharge causes or contributes to an exceedance of applicable water quality standards, the permittee must take corrective action as required, document the corrective actions as required, and report the corrective actions to the Department.
3.3. Numeric Effluent Limitations based on Effluent Limitations Guidelines. Permittees subject to one of the Effluent Limitation Guidelines identified in Part 1.4.3 must comply with the following limits:
3.3.1. The effluent limits referenced in the table below must be met, based on whether a facility has stormwater associated with the industrial activities listed below:

the requirement of 40 CFR 449.11(a)(1) to collect at least 60 percent of available Aircraft Deicing Fluid. 4 Only mine dewatering from surface mining activities for crushed stone, and construction sand and gravel, are subject to
the ELG-based limits. Mine dewatering from other surface mining activities (as noted in the definition in Part 8.20) are not subject to the ELG-based limits.
3.3.2. The facility must monitor each outfall discharging stormwater from any of the regulated activities described in the above table. The similar outfall monitoring provision as described in Part 3.8.1 is not available for numeric effluent limits monitoring.
3.4. Parameter Benchmark Monitoring. All facilities covered under this general permit are authorized to discharge from all permitted stormwater outfalls. All facilities are required to conduct monitoring and sampling of stormwater at each outfall as specified below. The benchmark concentrations are not effluent limitations; a benchmark exceedance, therefore, is not a permit violation. Benchmark monitoring data are primarily to be used by the facility staff to determine the overall effectiveness of BMPs and control measures in controlling the discharge of pollutants to the environment and to assist the facility in knowing when additional corrective action(s) may be necessary.

1 For airports where a single permittee or a combination of permitted facilities use more than 100,000 gallons of
glycol-based deicing chemicals or 100 tons or more of urea on an average annual basis, monitor all parameters in
ONLY those outfalls that collect runoff from areas where deicing activities occur. Monitoring is not required for
facilities with deicing activities that do not meet the above thresholds.
Page 20 Part 3
Permit Number ARR000000
3.5. Additional Monitoring Required by The Department. The Department may notify the facility of additional discharge monitoring requirements. Any such notice will briefly state the reasons for the monitoring, locations, and parameters to be monitored, frequency and period of monitoring, sample types, and reporting requirements. If a facility discharges to an impaired water with a Department approved or established TMDL, the Department will inform the facility if any additional monitoring requirements or controls are necessary for the discharge to be consistent with the assumptions of any available wasteload allocation in the TMDL.
3.6. Monitoring Period. The monitoring period is from January 1 to December 31 of a calendar year. The facility must monitor at least once within a calendar year.
Monitoring requirements in this permit begin on the effective date of the permit.
3.7. Monitoring Location. All samples must be taken at monitoring points specified in the NOI and SWPPP before the stormwater joins or is influenced by any other waste stream, or waterbody, unless otherwise approved in writing by the Department.
3.8. Sampling Associated with Monitoring Requirements. Sampling shall be conducted to capture stormwater with the greatest exposure to significant sources of pollution. Each stormwater outfall must be sampled and analyzed separately unless an outfall has been determined to be similar in accordance with Part 3.8.1 below.
3.8.1.
Similar Outfalls. When a stormwater outfall may be similar to another outfall at the facility, i.e., similar effluents based on a consideration of industrial activity, significant materials and management practices, and activities within the area drained by the outfall, the permittee may sample only the discharge point with the highest concentration of pollutants. The permittee must get approval of the similar outfall designation from the Department prior to monitoring. This provision is not available for discharges subject to the Effluent Limitations Guidelines in Part 1.4.3. The SWPPP must include documentation on how these determinations were made and the description of each point of discharge. The documentation should include the following information:
3.8.1.1. Location (latitude and longitude) of each of the similar outfalls; 3.8.1.2. Description of the general industrial activities conducted in the drainage area of each outfall; 3.8.1.3. Description of the control measures implemented in the drainage area of each outfall; 3.8.1.4. Description of the exposed materials located in the drainage area of each outfall that are likely to be
significant contributors of pollutants to stormwater discharges; and 3.8.1.5. Why the outfalls are expected to discharge similar effluents.
3.8.2.
Sampling Procedures. Samples and measurements taken as required shall be representative of the volume and nature of the monitored discharge. Stormwater must be sampled according to requirements below unless the Permittee submits an alternative plan as a modification of coverage and it is approved by the Department. Any approved alternative plan should be included in the SWPPP. If a Permittee is unable to sample during a monitoring period, they must document a justification in the Stormwater Annual Report for that period.
Sampling requirements and instructions are as follows:
3.8.2.1. Grab Sample. A minimum of one grab sample must be taken from each outfall within the first 30 minutes of a discharge resulting from a measurable storm event, as described in Part 3.8.2.2, or within the first 30 minutes of a discharge from holding ponds or basins, as described in Part 3.8.2.3. If it is not possible to collect the sample within the first 30 minutes of a discharge, the sample must be collected as soon as practical, and documentation must be kept with the SWPPP explaining why it was not possible to take samples within the first 30 minutes.
Page 21 Part 3
Permit Number ARR000000
3.8.2.2. Measurable Storm Events. All required monitoring must be performed on a storm event that results in an actual discharge from the site ("measurable storm event") that follows the preceding measurable storm event by at least 72 hours (3 days). The 72-hour (3-day) storm interval does not apply if the facility is able to document that less than a 72-hour (3-day) interval is representative for local storm events during the sampling period. In the case of frozen precipitation, the measureable storm event begins when melting produces a measurable discharge at the facility and ends when measurable discharge ceases at the facility.
3.8.2.3. Holding Ponds and Basins. Discharges from stormwater holding ponds and basins may be unrelated to the occurrence of a measurable storm event, as described in Part 3.8.2.2. Samples must be taken within the first 30 minutes of a discharge from holding ponds and basins, regardless of the occurrence of a measurable storm event. Both controlled and uncontrolled discharges are acceptable for sampling.
3.8.2.4. Adverse Weather Conditions. Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local flooding, high winds, electrical storms, or situations that otherwise make sampling impractical, such as drought or extended frozen conditions. When adverse weather conditions prevent the collection of samples according to the relevant monitoring schedule, a substitute sample must be taken during the subsequent qualifying storm event. The facility must document any failure to monitor as indicating the basis for not sampling during the usual reporting period.
3.8.2.5. Sampling Method. Analytical methods used to meet the monitoring requirements specified in this permit shall conform to the latest revision of the Guidelines Establishing Test Procedures for the Analysis of Pollutants contained in 40 CFR Part 136 or to the latest revision of Standard Methods for the Examination of Water and Wastewater (APHA), unless otherwise specified in this permit or approved in writing by the Department provided that such otherwise approved analytical method is the equivalent of that found in the guidance cited in this section or will result in more accurate analytical results or will have a lower detection limit. Note that 40 CFR Part 136 and Standard Methods for the Examination of Waste and Wastewater establish the maximum holding times for each parameter which must be met for sampling results to be considered valid. Some parameters have short holding times, such as pH, which should be analyzed immediately to be considered valid.
3.8.2.6. Records. For each sampling event, except for sampling from holding ponds and basins, the permittee shall record the date of the storm event sampled, rainfall measurements or estimates (in inches) of the storm event which generated the sampled runoff, and the duration between the storm event sampled and the end of the previous measurable storm event. The above information does not need to be recorded for sampling events for discharges from holding ponds and basins.
3.9. Exceptions to Monitoring Requirements.
3.9.1. Inactive and Unstaffed Facilities. Facilities that are inactive and unstaffed during an entire monitoring period will not be required to monitor during the inactive and unstaffed period. To be eligible for an inactive and unstaffed facility waiver, the permittee must certify the site is unstaffed and inactive and the pollutant generating activities are not occurring at the site. The certification must be signed in accordance with signatory requirements of Part 7.8 and kept with the Stormwater Pollution Prevention Plan. Unstaffed is defined as no staff assigned to the industrial or pollutant generating activities. A site may be "unstaffed" even when security personnel are present, provided that pollutant generating activities are not included in their duties.
3.9.2. Sampling Waiver. If a parameter is assigned to the facility per Part 3.4, the permittee may request in writing for sampling for that parameter to be waived. Adequate justification or data must be provided to the Department indicating as to why the assigned characteristic is not present at levels that would adversely affect the environment. The Department will review the request and all available information and provide a decision via correspondence.
Page 22 Part 3
Permit Number ARR000000
3.10. Alternatives to Parameter Benchmark Values. The permittee may develop alternatives to the parameter benchmark values, as follows.
3.10.1. The SWPPP must contain a full and complete description of the alternative(s) to the established parameter benchmark values listed in this permit, along with the justification for the selected alternative(s), why the alternative(s) is considered equivalent to the listed parameter benchmark value in protecting water quality (if the permittee is establishing a different value than the established parameter benchmark value), how the alternative(s) will be evaluated to determine equivalency with the established parameter benchmark value, and documenting on an annual basis the permittee's ability to successfully achieve the alternative(s) to the established parameter benchmark values.
3.10.2. The permittee shall submit the section of the SWPPP with the alternative(s) and the rationale to the Department for review. The Department shall review the alternatives and notify the facility of such a decision in writing within 60 days of receipt of the request. The permittee shall use the parameter benchmark values provided in Part 3.4 until written approval by the Department of the alternative benchmark value(s) is received.
3.11. Response to Monitoring Results Above Parameter Benchmark Values. This permit stipulates parameter benchmark value concentrations that may be applicable to a facility's discharge. The benchmark concentrations are not effluent limitations. Therefore, a benchmark exceedance is not a permit violation. Benchmark monitoring data are primarily for the facility to use for determining the overall effectiveness of control measures and to assist in knowing when additional corrective action(s) may be necessary to comply with permit requirements.
3.11.1. Data exceeding benchmarks: If a sampling result for any parameter exceeds the parameter benchmark value, the facility shall investigate the cause or source of the elevated pollutant levels, review the SWPPP, and determine and document a Corrective Action Plan to address the benchmark exceedance. The facility shall commence with the above process within 30 calendar days of the exceedance while immediately taking all readily apparent, reasonable steps necessary to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational, including cleaning up any contaminated surfaces so that the material will not discharge in subsequent storm events.
The Corrective Action Plan must contain the following: the results of the review; the corrective actions the permittee will take to address the benchmark excursion, including whether a SWPPP modification is necessary; and an implementation schedule with milestone dates and including alternative methods for implementing existing site controls or methods for implementing additional effective site controls, if the site controls have not already been implemented.
The permittee must document the date that corrective actions are initiated and are completed or expected to be completed. This documentation must be included in an annual report and a copy retained onsite with the SWPPP.
3.11.2. Natural background pollutant level: If the permittee determines, and the Department acknowledges, that the exceedances of a benchmark value is attributable solely to the presence of that pollutant in the natural background, the permittee is not required to perform corrective actions or additional benchmark monitoring, provided that the following are met:
3.11.2.1. The concentration of the benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background (data from previous monitoring may be used if it is less than 5 years old);
3.11.2.2. The permittee documents and maintains with the SWPPP the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. This must include in the supporting rationale any site specific data previously collected by the facility or others (including literature studies) that describe the levels of natural background pollutants in the stormwater discharge; and
Page 23 Part 3
Permit Number ARR000000
3.11.2.3. The Department must be notified that the benchmark exceedances are attributable solely to natural background pollutant levels. Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on-site or pollutants in run-on from neighboring sources which are not naturally occurring.

PART 4: STORMWATER POLLUTION PREVENTION PLAN (SWPPP)
Page 24 Part 4
Permit Number ARR000000
Each facility covered by this permit shall develop, implement, and comply with a SWPPP. The SWPPP shall be prepared in accordance with commonly accepted engineering practices. The SWPPP shall identify potential sources of pollution which may reasonably be expected to affect the quality of stormwater discharges associated with industrial activity from the facility. Required elements of the SWPPP, implemented in the form of BMPs in lieu of numerical limitations, are considered to be technology-based non-numeric limits based on 40 CFR 122.44(k)(3). The permittee must select, design, install, and implement control measures to comply with the Best Management Practices in Part 3.1, to meet the water quality-based effluent limitations in Part 3.2, and meet the limits contained in applicable Effluent Limitations Guidelines in Part 3.3; the SWPPP is the documentation of this process. The SWPPP must also include any additional BMPs as necessary to comply with state water quality standards and parameter benchmark values. New facilities must have a SWPPP developed and implemented before beginning operation. However, some components of a SWPPP are added over time (e.g. results of dry and wet weather inspections) and cannot be included in the first SWPPP. The Permittee must update the SWPPP as required by permit conditions. Facilities must implement the provisions of the SWPPP required under conditions of this permit.
4.1 Deadlines for SWPPP Preparation and Compliance. Deadlines for SWPPP preparation and compliance for stormwater discharge associated with industrial activity are as follows. Upon a showing of good cause, the Director may establish a later date in writing for preparing and coming into compliance with a SWPPP for a stormwater discharge associated with industrial activity that submits an NOI in accordance with requirements of this permit.

Page 26 Part 4
Permit Number ARR000000
4.2.4.4
Non-Stormwater Discharges. The SWPPP shall include measures to identify and eliminate the discharge of process wastewater, domestic wastewater, non-contact cooling water, and other illicit discharges to stormwater systems or to waters of the State. The SWPPP shall identify and ensure the implementation of appropriate pollution prevention measures for non-stormwater component(s) of the discharge allowed by Part 1.6.
The SWPPP shall also include a certification that the discharge has been tested or evaluated for the presence of illicit non-stormwater discharges and that all identified unauthorized discharges have been eliminated. The certification shall include the identification of potential significant sources of non-stormwater at the site, a description of the results of any test or evaluation for the presence of non-stormwater discharges, the evaluation criteria and testing method used, the date of any testing or evaluation, and the on-site drainage points that were directly observed during a test. Certifications shall be signed in accordance with Part 7.8 of this permit. Such certification may not be feasible if the facility operating the stormwater discharge associated with industrial activity does not have access to an outfall, manhole or other point of access to the ultimate conduit which receives the discharge. In such cases, the source identification section of the SWPPP shall indicate why the certification required by this part was not feasible, along with the identification of potential significant sources of non-stormwater at the site.
4.2.4.5 Salt Storage. The SWPPP must document the location of any storage piles containing salt used for deicing or other commercial or industrial purposes.
4.2.4.6 Sampling Data. A summary of existing discharge sampling data describing pollutants in stormwater discharges from the facility, including a summary of sampling data collected during the term of this permit.
4.2.5 Measures and Controls. Each facility covered by this permit shall develop a description of stormwater management controls appropriate for the facility and implement such controls. The appropriateness and priorities of controls in the SWPPP shall reflect identified potential sources of pollutants at the facility. The selection, design, installation, and implementation of these control measures must be in accordance with good engineering practices and manufacturer's specifications. Note that a permittee may deviate from such manufacturer's specifications where justification is provided for such deviation and include documentation of the rationale in the part of the SWPPP that describes the control measures. If control measures are found not to be achieving their intended effect of minimizing pollutant discharges, the control measures must be modified as expeditiously as practicable.
The following should be considered when selecting and designing control measures:
4.2.5.1 4.2.5.2 4.2.5.3 4.2.5.4
4.2.5.5 4.2.5.6
preventing stormwater from coming into contact with polluting materials is generally more effective, and less costly, than trying to remove pollutants from stormwater; using control measures in combination is more effective than using control measures in isolation for minimizing pollutants in stormwater discharges; assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures that will achieve the limits in this permit; minimizing impervious areas at the facility and infiltrating runoff onsite (including bioretention cells, green roofs, and pervious pavement, among other approaches) can reduce runoff and improve groundwater recharge and stream base flows in local streams, although care must be taken to avoid ground water contamination; attenuating flow using open vegetated swales and natural depressions can reduce in-stream impacts of erosive flows; conserving or restoring of riparian buffers will help protect streams from stormwater runoff and improve water quality; and
Page 27 Part 4
Permit Number ARR000000
4.2.5.7 using treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants.
For guidance on potential pollutant sources and controls that should be considered in development of the SWPPP for a specific type of industry, refer to EPA's Multi-Sector General Permit (available online via link at: (https://www.epa.gov/npdes/stormwater-discharges-industrialactivities#msgpdocuments).

Mr. York,
I will have ECCI fix the typo and email you the updated copy later today. In regards to the MNA of the wetland area, I think the results from additional soil tests (probably next week) with all Plan parameters will be very helpful for future discussions regarding this area.
I am going to try and schedule a couple days next week for ECCI to sample the wetland area, residential properties in the proximate area of the release, and the area behind the waste pile. These are the areas that require some judgment in the area sampled, so I would like the DEQ to be present for these. I will be in contact over the next day or two regarding some dates next week that might work for a DEQ representative to accompany ECCI.
Feel free to give me a call or email me if any additional comments/questions are raised. Thanks!

Mr. Anthony,
Our comments are very minor:
Section 5.4 apparent typo - "In Figure 6..." we believe should read, "In Figure 5..." ATI is proposing MNA for the wetland area. Office of Land Resources (OLR) is sorting through the data provided
of any samples for this identified area. We anticipate further discussion of this proposal based on review of the data, however this concern has previously been addressed in DEQ's response comment 15 in the 21st December letter to ATI. We anticipate any further discussion to be collaborative in nature.
Please feel free to contact me if you would like to discuss. I will attempt to get in front of my bosses asap regarding the status of the Remediation Plan and whether I may proceed with formal acceptance of the plan.
Thanks,

2.0 BACKGROUND
Anthony Timberlands Inc. (ATI) was notified in September 2022 of a release of unknown origins. The release of petroleum product and/or high oxygen demanding constituents impacted the unnamed tributary to Town Creek, Town Creek, and Chatman Creek. The Arkansas Department of Energy and Environment, Division of Environmental Quality (DEQ) and the U.S. Environmental Protection Agency (EPA) identified ATI's Malvern facility as a responsible party (RP). Upon notification, ATI cooperated and coordinated with DEQ and EPA to quickly begin emergency response operations to recover free product and debris.
3.0 EMERGENCY RESPONSE
ATI contracted TAS Environmental Services, LP (TAS) for on-scene response. TAS mobilized and immediately placed oil absorbent booms and pads downstream of the facility. A vacuum truck was utilized to remove most of the liquid in ATI's concrete ditch immediately downstream of the facility. Clean sawdust was used to absorb the remaining liquid in the concrete ditch. The saturated material was then removed and

Remediation and Maintenance Plan
placed in roll-off containers for proper disposal. TAS also placed oil absorbent booms and pads in Town Creek in areas with free product and/or sheening.
The EPA met with ATI on October 17th and outlined an "area of concern" (AOC) where free product was observed. The AOC began at the unnamed tributary along Walco Road and ended shortly after the old railroad crossing on Town Creek. ATI coordinated with EPA to identify a scope of work to implement emergency response activities addressing the area of concern. TAS focused the cleanup on this area, and once most of the free product in Town Creek was removed, a four-inch diesel powered pump was used to create flow and push the remaining product to a collection point. TAS completed the removal of free product from the EPA identified area of concern by October 29th and began focus on sheen collection and removal by the use of oil booms throughout the area.
4.0 PURPOSE
Following the emergency response actions, DEQ requested ATI prepare a plan to address, if necessary, any residual free product, sheening, or oil residues and to temporarily sample for potential impacts to the area of release. ATI contracted ECCI to consult on additional response operations and to prepare the requested Remediation and Maintenance Plan. The following Remediation and Maintenance Plan is intended to outline the monitoring and, if necessary, additional remediation of downstream impacts to the unnamed tributary to Town Creek, Town Creek, and Chatman Creek. The remediation activities are intended to improve the current water quality of the unnamed tributary, Town Creek, and Chatman Creek back to the stream conditions prior to the release of petroleum products. The completion of this plan will be determined by ATI's sampling and observations detailed within this document.
ATI will rely on the Arkansas Pollution Control and Ecology Commission (APC&EC) Rule 2, EPA Regional Screening Levels (RSLs) summary table, EPA Region 4 Ecological Screening Values (ESVs), and DEQ published guidance to set both numeric and narrative targets to determine end points for this plan. These numeric and narrative targets will apply to the Constituents of Concern (COCs) discussed in Section 5.2.2 and detailed below.
ECCI

January 2023
Anthony Timberlands, Inc.
Remediation and Maintenance Plan
Rule 2 sets a narrative target for Oil and Grease (O&G) in section 2.410 as follows, "that oil, grease, or petrochemical substance shall not be present in receiving waters to the extent that they produce globules, other residue or any visible, colored film on the surface; coat the banks and /or bottoms of the waterbody; or adversely affect any of the aquatic biota."
Rule 2 sets numeric targets for dissolved oxygen in both small and large watersheds. In the primary season a value of 5 mg/L is applicable. During the critical season a value of 3 mg/L is applicable. The value of 50 mg/L will be used for the COD target endpoint based on DEQ Guidance.
ATI will conduct surface soil sampling on the Malvern facility, specifically in areas down gradient of the wood waste pile. Soil samples will also be collected from downstream areas where surface water samples are also collected and areas identified as having potential impacts. Soils analysis will be compared to the EPA RSLs and ESVs to identify if further remediation is necessary.
The Scope of Work (SOW) sent to ATI by the EPA lists tasks necessary for proper cleanup. The list includes: recover free product, maintain boom and physical barriers and removing all oiled vegetation within the impacted area. ATI has removed much of the free product and is now in the maintenance phase of the removal. Booms have been deployed in the area of concern. The booms are inspected and replaced as needed. ATI has developed a plan to remove impacted soils from the streambed in the unnamed tributary to Town Creek from the Walco Bridge downstream to the culvert just prior to the confluence with Town Creek. Excavation equipment will utilize wood mats to access portions of the unnamed tributary. The mats will be removed when the excavation is complete. The area of the unnamed tributary where the work is planned is depicted in Figure 4.
The wetland area south of the unnamed tributary and west of the Walco Bridge has had some impacted soils and vegetation. ATI plans to harvest or remove vegetation that has been soiled with the oily residue from the release. This will take place during the dormant season and will involve cutting impacted undergrowth vegetation, leaving the root structure intact, and allowing it to revegetate naturally. Trees will not be cut in

5.3 SOIL SAMPLING
This section provides a summary of the sampling and analysis activities that will be conducted to assess the current conditions of the soils on the facility and in the areas of concern downstream.
5.3.1 Soil Sampling on the ATI Facility ATI will conduct surface soil sampling on the Malvern facility, specifically in areas down gradient of the wood waste pile. Ten (10) sample locations have been selected for the on-site surface soil samples. The proposed sample locations are depicted in Figure 2 and will be taken in consultation with a DEQ representative on-site. Soil samples will be analyzed for parameters listed in Table 5.3 applicable to soils, TPH, SVOCs and VOCs. If VOCs are non-detect for that sample, no additional VOCs will be required for that area during confirmation sampling. Results will be compared to RSL tables and ESVs. 5.3.2 Soil Sampling Downstream In addition to the soil samples noted in Section 5.3.1, the facility will also take soil samples at the following downstream locations:
Along the creek bank at SW3, SW4 Alternate, SW5, and SW6 Alternate In the creek bed at SW3, SW4 Alternate, SW5, and SW6 Alternate The wetland area south of the unnamed tributary. Sample locations will

locations will be chosen in consultation with a DEQ representative on-site. A map of all the downstream sample locations will be created after the locations are chosen. Soil samples will be analyzed for those parameters in Table 5.3 applicable to soils, TPH, and SVOCs and VOCs. Results will be compared to RSL tables and ESVs.
5.4 SOIL REMEDIATION
ATI has identified the following two areas as requiring soil remediation by means of excavation. These locations are shown below.

1) The unnamed tributary from the Walco bridge extending to the culvert at 3421'49.05" N and - 9249'50.90" that was discussed in Section 4.0. This area is depicted in Figure 4.
2) ATI facility between the clarifier and the concrete ditch. This area is depicted in Figure 5.
Once excavation has been completed, confirmation samples will be collected based on guidance provide by DEQ, one (1) sample every 20 linear feet along a linear spill path or five (5) samples every 400 square feet (one for each perimeter length and one floor) in nonlinear excavated areas will be collected. ATI will collect samples from known contaminated areas (wetland area and/or unnamed tributary) and analyze them for the parameters listed in Table 5.3 that are applicable to soils, TPH, SVOCs and VOCs. These test results will determine which parameters will be analyzed in the postexcavation confirmation samples. Once test results are known, this section will be updated with the chosen testing parameters. Results will be compared to RSL and ESVs to determine whether additional soil should be excavated.
In Figure 5, ATI has identified the wetland area south of the unnamed tributary described in Section 4.0. ATI proposes to let this area be remediated through monitored natural attenuation. ATI proposes to monitor this area quarterly for two years. Samples will be analyzed for VOCs, SVOCs and RCRA 8 Metals. After two years, a determination will be made about the effectiveness of MNA and the sampling schedule modified as needed.
Test results from locations noted in Sections 5.3 and 5.4 above will indicate whether additional soil remediation is necessary.
5.5 WASTE MANAGEMENT
Excavated soils removed during the remediation will be profiled and placed in roll off containers. Soils will be managed and disposed of in accordance with all applicable regulations. Soils will be removed from the site as soon as practicable, generally within 10 days.

6.0 ADDITIONAL TREATMENT AND CONTROLS
ATI is evaluating and will implement additional treatment and controls, as necessary, for the unnamed tributary to Town Creek, and Town and Chatman Creeks downstream of the facility.
6.1 UNNAMED TRIBUTARY TO TOWN CREEK, TOWN AND CHATMAN CREEKS TREATMENT AND CONTROLS
ATI will continue to maintain booms in the unnamed tributary, Town Creek and Chatman Creek downstream of the facility until such a time that all free product, visible sheening, and residue are removed. Boom locations are depicted in Figure 3. As discussed in section 5.5, ATI will excavate the unnamed tributary to Town Creek to remove sediment from the bottom that could cause future sheening. The location of the excavation of the unnamed tributary to Town Creek is found in Figure 4. The excavation will take place under US Army Nationwide Permit (NWP) 20. Additionally, a Short-Term Activity Authorization (STAA) will be obtained from DEQ.
ATI will respond to any reported instances of free product, visible sheening, or residue of the release.
6.2 FACILITY TREATMENT AND CONTROLS
In response to DEQ's initial notification and facility investigation, ATI also plans to implement additional on-site controls and treatment for stormwater, spills, drips, and non-stormwater process related wastewater.
ATI has placed a liner and booms under all the existing bulk storage tanks and booms around equipment reservoirs. The liner is rolled around oil absorbent booms to create a temporary containment area. ATI is in the process of ordering steel or concrete secondary containment for all existing oil storage tanks.
The facility has also made changes to address runoff from the wood waste pile around the pond as well. ATI constructed a drainage trench on the back side of the pile to capture stormwater and firefighting water. The trench is maintained by pumping any water captured directly to the log yard pond.
Finally, TAS, while completing emergency response activities, used a vacuum truck to remove free product from ATI's oil water separator (OWS) onsite. The sediment

in the OWS was removed and placed in a roll-off container for proper disposal, offsite. ATI has completed improvements to the clarifier by increasing the wall height of the final chamber and adding five 12-inch diameter outlet pipes in place where three 6-inch pipes were previously. This will significantly increase the flow potential and minimize the possibility of an overflow event. The P.E. certified plans are included in Attachment 3 and will also be included in the forthcoming NPDES permit application.
ATI has started the process of applying for an industrial wastewater discharge permit.
7.0 MAINTENANCE PLAN
The Maintenance Plan (MP) will address the methods of continued monitoring and collection of oil residue of the release, in-stream water quality assessment, and a schedule for the planned frequency of monitoring of Town and Chatman Creeks. During a meeting with DEQ staff on October 27, 2022, the Maintenance Plan was discussed and DEQ staff indicated that the end goal was to remove the visible oil sheen and oil residue from the downstream area of concern and to return the water quality to its condition prior to the release. Maintenance activities will continue until the narrative and numeric water quality standards established in Section 4.0 are met downstream.
7.1 WATER QUALITY ASSESSMENT
The downstream water quality will be assessed using dry weather and rain event sampling protocol. The dry weather sampling will be collected at least a week apart if no precipitation has occurred. The rain event sampling will include three rounds of sampling each after a measurable rainfall. The parameters for the both the dry weather and rain event sampling will be those listed in Table 5.3. The results of these samples will be compared to the numeric and narrative targets outlined in above in Section 4.0 to complete the water quality assessment. The stated goal of the assessment is to ensure water quality has returned to the conditions existing prior to the release of petroleum products in the unnamed tributary, Town Creek, and Chatman Creek.

7.2 METHODS OF CONTINUED MONITORING OF RESIDUE
ATI will continue to monitor the downstream areas for the presence of oil sheen and oil residue. Maintenance activities will continue to remove visible oil from the surface and the oil residue on the streambed substrate from downstream locations. ATI will contract with a third-party response company to conduct the on-going maintenance. The unnamed tributary will be inspected from the point where the clarifier discharge enters the ditch to the confluence of Town Creek. Town Creek will be inspected from the confluence of the unnamed tributary to the sampling location SW-3. The downstream sample locations along Town and Chatman Creeks will also be inspected twice per calendar week for a period of 90 days. Water quality parameters pH, DO, and temperature will be collected during these inspections. Oil absorbent booms and pads (as needed) will be utilized during the maintenance activities as well.
7.3 OIL OBSERVED ON THE SURFACE
Oil absorbent booms will be placed downstream of the facility to collect any oil residue that becomes mobilized during rain events. The booms will be securely installed and maintained. Oil absorbent pads will be utilized by ATI representatives, as needed, to actively remove the oil from the surface of the water as necessary.
7.4 OIL DEPOSITS ON STREAM BANKS AND BOTTOMS
Stream bottom sediment and stream bank soil samples will be collected at the surface water sample locations; SW-3, SW-4 Alternate, SW-5, and SW-6 Alternate. All soil samples will be analyzed for the parameters listed Table 5.3 applicable to soils, TPH, VOCs, and SVOCs. The concrete lined ditch, the unnamed tributary to Town Creek, Town Creek, and Chatman Creek will be monitored for oil residue deposited on the stream bottom. If ATI identifies oil residue on the streambed through visual observations during the inspections, then a vacuum truck will be utilized to remove such deposits provided they are in a well-defined and easily accessible area. If deposits are in an in-accessible area or a vacuum truck cannot effectively remove them, then deposits on stream bottoms will be left to remediate naturally. ATI will also make observations looking for migrations of the deposits into the accessible areas. ATI will contract with a third party to conduct the maintenance activities.

8.0 SCHEDULE OF MAINTENANCE ACTIVITIES
Maintenance activities such as deploying oil absorbent booms and pads are ongoing. Oil absorbent booms along the unnamed tributary to Town Creek, Town Creek, and Chatman Creek will be monitored and maintained on a weekly schedule. The immediate and ongoing cleanup response is projected to stay at current levels until approval of this plan. At that point, a smaller field team will be in place to maintain oil absorbent booms.
8.1 SURFACE WATER SAMPLING
Upon approval of the Plan, ATI will begin to collect samples from the downstream sample locations (SW2, AT7, SW3, SW4 Alternate, SW5 and SW6 Alternate) after three different measurable (0.25 inches or greater) rain events. Samples will be analyzed for those parameters listed in Table 5.3. There will also be three (3) dry weather samples collected from the downstream sample locations (SW2, AT7, SW3, SW4 Alternate, SW5 and SW6 Alternate). Dry weather samples will be collected at least one week apart if

not rainfall occurs between events. Dry weather samples will also be analyzed for the parameters in Table 5.3.
8.2 SOIL SAMPLING
Upon approval of this plan soil sampling will be conducted on the ATI facility and at the downstream surface water locations. Soils from the stream banks and stream bottoms will be collected. Soils from residential properties in the proximate area of the release will also be collected. The soils will be analyzed for the parameters in Table 5.3 applicable to soils, TPH, VOCs, and SVOCs. The results will be compared with RSLs and ESVs. The soil sampling locations will be selected judgmentally by ATI and DEQ, with the exception of the locations where surface water will also be collected.
8.3 VISUAL INSPECTIONS
Twice weekly visual inspections for sheening and/or free product will occur at downstream of the ATI facility. The entire length of the unnamed tributary will be inspected. Town Creek from the confluence of the unnamed tributary to the rail road bridge will also be inspected. The surface water sample locations will also be inspected twice weekly. These inspections are scheduled to continue for three months. The schedule will be revaluated after this time. DO, pH, and temperature will be recorded during each inspection.
9.0 ECOLOGICAL CONSIDERATIONS
ATI will have discussions with the Arkansas Game and Fish Commission (AGFC) regarding the necessity of a biological evaluation of fish and mussel populations in the affected area.
10.0 COMMUNITY AND ENGAGEMENT PLAN
ATI will send out a weekly summary of activities via email to all impacted downstream landowners who have been identified.
