OVERVIEW On April 2, 2019 an eight inch product pipeline carrying “Natural Gasoline” breached (39.520785o N, -87.084614o W), resulting in the discharge of approximately 12,600 gallons into a tributary of Billy Creek, Clay County, Indiana (the “incident”) (Fig. 1). The purpose of this Report is to briefly summarize the steps taken by the natural resource Trustees [the State of Indiana Department of Environmental Management (IDEM) and Department of Natural Resources (IDNR), and the U.S. Fish and Wildlife Service] to complete the preassessment phase of the Natural Resource Damage Assessment and Restoration (NRDAR) process pursuant to 15 C.F.R. Part 990, Subpart D. Specifically, this Report describes the Trustees’ jurisdiction to pursue restoration activities under the Oil Pollution Act (OPA), including a brief description of the incident, as well as a description of the natural resources under the trusteeship of the Trustees that may have been injured as a result of the incident. This report summarizes the observed effects of the incident on aquatic and terrestrial organisms under our trusteeship. The documentation of the impacts during the response will aid in the development of feasible restoration actions.

Spill Incident We received notice via the National Response Center in the morning of April 2, 2019 that a 8” product pipeline owned by Marathon Pipeline LLC had failed near Knightsville, Clay County, Indiana. An estimated 300 barrels (12,600 gallons) of natural gasoline was released impacting soil and an unnamed tributary of Billy Creek. IDEM deployed several OSCs to the site. Natural resource trustee personnel were in communication with the USEPA and IDEM spill response staff several times on April 2, 2019 being updated on the spill and providing natural resource technical assistance. While on-site on April 3, 2019 US Fish and Wildlife Service (USFWS) and IDEM natural resource trustee staff provided technical assistance to IDEM and Marathon Pipe Line LLC. We participated in walking the creek banks, making wildlife observations, evaluating sheen and creek bank conditions. Investigations revealed that there were dead fish and ducks on the unnamed tributary and Billy Creek. Dead animals were recovered as safety permitted in the second day of recovery efforts. Affected fish and wildlife included 8 ducks, one Louisiana waterthrush, nearly 400 small fish and minnows, several salamanders and frogs. Some of these deceased animals had GPS coordinates collected. These samples were placed in several coolers with ice and taken to the USFWS office where the bird carcasses were stored in a locked freezer at -4oC. The fish, salamanders and frog samples were placed in 10% neutral buffered formalin to arrest the decomposition process so that species identification and aging could take place. US EPA deployed their START contractor to conduct air monitoring due to the close proximity of several residences. Response efforts ran continuously for many days (Fig. 2). IDEM OSCs led the response oversight and U.S. EPA continued to provide regional assistance and air monitoring support. were onsite to advise the spill response activities and assess natural resource conditions. On April 3, 2019 US EPA and Marathon conducted air monitoring near residential properties and all results near private residences have resulted in no detections of pollutants. Marathon continued spill recovery efforts and no oil reached Eel River or the Wabash River. Marathon completed the cleanup and remediation activities under IDEM’s oversight.

Billy Creek and Natural Resource Injuries Billy Creek is in northeastern Clay County approximately 1 mile east of Brazil, Indiana. Billy Creek is a tributary to Croys Creek which flows into the Eel River just downstream of Cagels Mill Lake in Putnam County (Fig. 3). The stream segments impacted have a combined catchment basin of 15.96 km2. Land use in this region of Indiana is predominantly agricultural (62%) National Hydrology Dataset Plus (version 2). Corn and soybeans are the two major crops. The mean daily discharge at the upper segment of Billy Creek nearest the spill is 3.31 cubic feet per second (NHDP). Despite the significant amount of agriculture in this area, the creek is surrounded by high quality forested riparian and wetland habitat. The Billy Creek ecosystem is home to a wide range of fish and invertebrate species. Indiana Department of Environmental Management (IDEM) routinely inventories the biotic integrity of Indiana streams on a 5 year rotating basis. The regional expectations of the biological integrity of central Indiana (Eastern Corn Belt Plain, ECBP) water resources was developed by Simon and DuFour (1998) and has been calibrated to accommodate headwater stream conditions. Best achievable conditions in the ecoregion is based on the concept of “least impacted” reference conditions for establishing baseline conditions (Hughes et al. 1986, Hughes 1995). This calibration uses an ecological classification that recognizes expected differences in biological assemblages based on potential natural vegetation, soils, land forms, and climate (Omernik 1987). Using only the inventory of the deceased fish community (Table 1) this stretch of Billy Creek achieved an Index of Biotic Integrity (IBI) score of 42 (Table 2). According to the ECBP the spill impact zone would be rated as “Fair” in comparison to highest achievable conditions. Many of the fish in this sample were 4 plus years old.

Two federally listed species, the endangered Indiana bat (Myotis sodalis), and the threatened northern long-eared bat (Myotis septentrionalis) have been frequently found in areas near to this spill impact zone (USFWS undated), and in similar habitats to those impacted in the Billy Creek watershed (Fig. 3). In addition, several amphibians were impacted by the spill. Although a relatively small area was impacted by this spill (Fig. 1), it was high value wildlife habitat as adverse impacts to migratory bird were extraordinary. The death of 8 wood ducks in the peak of the breeding season is a substantial loss. The loss of a Louisiana waterthrush is also significant. Waterthrush are “bioindicators of riparian ecosystem integrity” (Frantz et al. 2018) being found in contiguous, high value habitats (Mattsson et al. 2009). They feed on aquatic macro-invertebrates (Prosser and Brooks 1998) from “well developed pool and riffle areas” (Frantz et al. 2018). Accordingly, natural resources under the trusteeship of the Trustees have been injured as a result of the releases of natural gasoline at this incident.

It is established that “natural gasoline” is “toxic to aquatic life with long lasting effects” (Marathon 2016). This was confirmed by the observations and collections of fish, salamanders and frog along the unnamed tributary and Billy Creek. Some scavenging likely took place as small wading bird footprints (likely from a green heron) were observed in the impact zone (D. Sparks pers. obs. 4-3-2019). Concentrations of Petroleum Product in Billy Creek

It is estimated that approximately 12,600 gallons of natural gasoline was released into the Billy Creek. This petroleum product was different than anything we had ever had experience with and so we pursued chemical analyses. The trustees asked the US Coast Guard’s Marine Safety Laboratory (MSL) if they would analyze feathers to describe the petroleum product for us in detail. Having reviewed the “natural gasoline” SDS that we had received from Marathon, MSL stated that their routine analytical approach was not designed to work for such an extremely light and volatile product. This led us to explore analytical opportunities with our standing analytical contractors. After coordinating with our Analytical Control Center (ACF) we contracted with Alpha Woods Hole Analytical Laboratory (Alpha) to analyze feathers clipped from these 9 birds for oil fingerprint analysis. Analytical Methods The USFWS Analytical Control Facility let this contract to Alpha Woods Hole Labs for P.I.A.N.O. (Parafinic, Isoparafinic, Aromatic, Naphthenic, Olefinic) Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry (GC/MS). PIANO Volatile organic

compound analysis is applicable to the determination of purgeable organics with a boiling point below 270°C in water and other aqueous samples (surface and saline waters, groundwaters, domestic and industrial wastes), oils/NAPL, and solid samples (soils, sediments and sludges).

Volatile organic compound analysis by purge and trap GC/MS can be used to quantify organic compounds that have boiling points less than 270ºC. The method is applicable to all types of matrices, and to all of the compounds listed in Table X. These volatile organic compounds can accurately be determined in the range of 2μg/L to 200μg/L for aqueous samples, in the range of 2μg/Kg to 200μg/Kg for solid samples, and 10mg/Kg to 1000mg/Kg for oil. NAPL sample results that do not require dilution.

Alpha received nine tissue/feather samples from the USFWS Bloomington, Indiana Field Office for VO/PIANO analyses. The acceptable precision of this data set was assessed utilizing reported relative percent difference (RPD) values of lab generated spiked duplicates. The acceptable RPD criterion for samples with reported analyte concentration ranges between 2-10 times the Limit of Detection (LOD) is a value of less than 17.3%. The acceptable criterion for reported analyte concentrations greater than 10 times the LOD is a value of less than 8.6%. The principal measures of accuracy used to assess the quality of this data set were lab generated spike duplicates. The average recovery of most analytes from spiked tissue, soil/sediment and water should be between 60 and 130 percent. There were no Blank Frequency Anomalies, Reference Material Frequency Anomalies, Mass Spec Frequency Anomalies, Blank Anomalies, Duplicate Anomalies, Spike Anomalies, S.R.M. Anomalies. The contract required amount of 5% precision samples were included with this data set. The lab performed lab generated spiked duplicates which were used to assess the acceptable reproducibility of the data set. The contract required amount of 5% accuracy samples were included with this data set. The lab performed lab generated spikes and lab generated spiked duplicates which were used to assess the acceptable accuracy of the data set. The Service does not have contract required LODs for VO/PIANO analytes since they are not mandatory analytes. The LODs provided by the lab should be used in assessing the data.: This analytical analysis (ACF catalog 3020099) received QA/QC approval on September 30, 2019 by Steve Boateng and Brenda Bryant (US FWS Analytical Control Facility). Between 67 and 99 compounds were detected on these feather samples (Table 3). Total VOC concentrations detected ranged from 746 ppm wet weight in the Louisiana waterthrush sample to a high of over 53,000 ppm wet weight in one of the wood duck samples. The description of “natural gasoline” in the Safety Data Sheet provided by Marathon (Appendix I) matched Alpha’s analytical results of the oil from the deceased bird’s feathers (Table 3). In sum, and as explained more fully herein, the response actions have not adequately addressed, or are not expected to address, the injuries to natural resources resulting from the incident.

General Advice: In case of accident or if you feel unwell, seek medical advice immediately (show directionsfor use or safety data sheet if possible).

Inhalation: Remove to fresh air. If not breathing, institute rescue breathing. If breathing is difficult,ensure airway is clear, give oxygen and continue to monitor. If heart has stopped,immediately begin cardiopulmonary resuscitation (CPR). Keep affected person warm and atrest. If symptoms or irritation occur, call a physician.

Skin Contact: Immediately wash exposed skin with plenty of soap and water while removing contaminatedclothing and shoes. May be absorbed through the skin in harmful amounts. Get medicalattention if irritation persists. Any injection injury from high pressure equipment should beevaluated immediately by a physician as potentially serious (See NOTES TO PHYSICIAN).

Place contaminated clothing in closed container until cleaned or discarded. If clothing is tobe laundered, inform the person performing the operation of contaminant's hazardousproperties. Destroy contaminated, non-chemical resistant footwear.

Eye Contact: Flush immediately with large amounts of water for at least 15 minutes. Eyelids should beheld away from the eyeball to ensure thorough rinsing. Gently remove contacts whileflushing. Get medical attention if irritation persists.

Ingestion: Do not induce vomiting because of danger of aspirating liquid into lungs, causing seriousdamage and chemical pneumonitis. If spontaneous vomiting occurs, keep head below hips,or if patient is lying down, turn body and head to side to prevent aspiration and monitor forbreathing difficulty. Never give anything by mouth to an unconscious person. Keep affectedperson warm and at rest. GET IMMEDIATE MEDICAL ATTENTION.

Most important signs and symptoms, both short-term and delayed with overexposure

Notes To Physician: INHALATION: This material (or a component) sensitizes the myocardium to the effects ofsympathomimetic amines. Epinephrine and other sympathomimetic drugs may initiatecardiac arrhythmias in individuals exposed to this material. Administration ofsympathomimetic drugs should be avoided.

SKIN: Leaks or accidents involving high-pressure equipment may inject a stream of materialthrough the skin and initially produce an injury that may not appear serious. Only a smallpuncture wound may appear on the skin surface but, without proper treatment anddepending on the nature, original pressure, volume, and location of the injected material,can compromise blood supply to an affected body part. Prompt surgical debridement of thewound may be necessary to prevent irreversible loss of function and/or the affected bodypart. High pressure injection injuries may be SERIOUS SURGICAL EMERGENCIES.

INGESTION: This material represents a significant aspiration and chemical pneumonitishazard. Induction of emesis is not recommended.

5. FIRE-FIGHTING MEASURESSuitable extinguishing mediaFor small fires, Class B fire extinguishing media such as CO2, dry chemical, foam (AFFF/ATC) or water spray can be used. Forlarge fires, water spray, fog or foam (AFFF/ATC) can be used. Firefighting should be attempted only by those who are adequatelytrained and equipped with proper protective equipment.

Unsuitable extinguishing mediaDo not use straight water streams to avoid spreading fire.

Specific hazards arising from the chemicalThis product has been determined to be an extremely flammable liquid per the OSHA Hazard Communication Standard and shouldbe handled accordingly. May accumulate electrostatic charge and ignite or explode. Vapors may travel along the ground or bemoved by ventilation and ignited by many sources such as pilot lights, sparks, electric motors, static discharge, or other ignitionsources at locations distant from material handling. Flashback can occur along vapor trail. For additional fire related information,see NFPA 30 or the Emergency Response Guidebook 128.

Hazardous combustion productsSmoke, carbon monoxide, and other products of incomplete combustion.

Explosion dataSensitivity to Mechanical Impact No.Sensitivity to Static Discharge Yes.

Special protective equipment and precautions for firefightersFirefighters should wear full protective clothing and positive-pressure self-contained breathing apparatus (SCBA) with a fullface-piece, as appropriate. Avoid using straight water streams. Water may be ineffective in extinguishing low flash point fires, butcan be used to cool exposed surfaces. Avoid excessive water spray application. Water spray and foam (AFFF/ATC) must beapplied carefully to avoid frothing and from as far a distance as possible. Keep run-off water out of sewers and water sources.

Additional firefighting tacticsFIRES INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders ormonitor nozzles. Cool containers with flooding quantities of water until well after the fire is out. Do not direct water at source of leakor safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration oftank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles: if this isimpossible, withdraw from area and let fire burn.

EVACUATION: Consider initial downwind evacuation for at least 1000 feet. If tank, rail car or tank truck is involved in a fire,ISOLATE for 5280 feet (1 mile) in all directions; also, consider initial evacuation of 5280 feet (1 mile) in all directions.

Personal precautions: Keep public away. Isolate and evacuate area. Shut off source if safe to do so. Eliminate allignition sources.

Protective equipment: Use personal protection measures as recommended in Section 8.

Emergency procedures: Advise authorities and National Response Center (800-424-8802) if the product hasentered a water course or sewer. Notify local health and pollution control agencies, ifappropriate.

Environmental precautions: Avoid release to the environment. Avoid subsoil penetration.

Methods and materials forcontainment:

Contain liquid with sand or soil. Prevent spilled material from entering storm drains, sewers,and open waterways.

Methods and materials for cleaningup:

Use suitable absorbent materials such as vermiculite, sand, or clay to clean up residualliquids. Recover and return free product to proper containers. When recovering free liquidsensure all equipment is grounded and bonded. Use only non-sparking tools.

7. HANDLING AND STORAGESafe Handling Precautions: NEVER SIPHON THIS PRODUCT BY MOUTH. Use appropriate grounding and bonding

practices. Static accumulating flammable liquid. Bonding and grounding may be insufficientto eliminate the hazard from static electricity. Do not expose to heat, open flames, strongoxidizers or other sources of ignition. Vapors may travel along the ground or be moved byventilation. Flashback may occur along vapor trails. No smoking. Avoid repeated andprolonged skin contact. Avoid breathing vapors or mists. Use only with adequateventilation. Use personal protection measures as recommended in Section 8. Use onlynon-sparking tools. Exercise good personal hygiene including removal of soiled clothingand prompt washing with soap and water. Do not cut, drill, grind or weld on emptycontainers since explosive residues may remain. Refer to applicable EPA, OSHA, NFPAand consistent state and local requirements.

Hydrocarbons are basically non-conductors of electricity and can become electrostaticallycharged during mixing, filtering, pumping at high flow rates or loading and transferoperations. If this charge reaches a sufficiently high level, sparks can form that may ignitethe vapors of flammable liquids. Sudden release of hot organic chemical vapors or mistsfrom process equipment operating under elevated temperature and pressure, or suddeningress of air into vacuum equipment may result in ignition of vapors or mists without thepresence of obvious ignition sources. Nozzle spouts must be kept in contact with thecontainers or tank during the entire filling operation.

Portable containers should never be filled while in or on a motor vehicle or marine craft.Containers should be placed on the ground. Static electric discharge can ignite fuel vaporswhen filling non-grounded containers or vehicles on trailers. The nozzle spout must be keptin contact with the container before and during the entire filling operation. Use onlyapproved containers.

A buildup of static electricity can occur upon re-entry into a vehicle during fueling especiallyin cold or dry climate conditions. The charge is generated by the action of dissimilar fabrics(i.e., clothing and upholstery) rubbing across each other as a person enters/exits thevehicle. A flash fire can result from this discharge if sufficient flammable vapors arepresent. Therefore, do not get back in your vehicle while refueling.

Cellular phones and other electronic devices may have the potential to emit electricalcharges (sparks). Sparks in potentially explosive atmospheres (including fueling areassuch as gas stations) could cause an explosion if sufficient flammable vapors are present.Therefore, turn off cellular phones and other electronic devices when working in potentiallyexplosive atmospheres or keep devices inside your vehicle during refueling.

Delayed and immediate effects as well as chronic effects from short and long-term exposure

GASOLINE: Lifetime inhalation studies with full vaporized gasoline (67, 292 and 2,056ppm) produced kidney damage and kidney tumors in male rats but not in female rats ormale and female mice. Female mice developed a slightly higher incidence of liver tumorscompared to controls at the highest exposure level. Results from separate studies withcompounds producing similar effects, i.e., 1,4-dichlorobenzene and perchloroethylene,have shown that the kidney damage and kidney tumors develop via the formation ofalpha-2u-globulin, a mechanism unique to the male rat. Humans do not formalpha-2u-globulin, therefore, tumors resulting from this mechanism are not relevant inhumans. The biologic significance of the mouse liver tumor response with regard to human

health risk not clear at this time. Altered mental state, drowsiness, peripheral motorneuropathy, irreversible brain damage (so-called Petrol Sniffer's Encephalopathy), delirium,seizures, and sudden death have been reported from repeated overexposure to somehydrocarbon solvents, naphthas, and gasoline.

PENTANES: Studies of pentane isomers in laboratory animals indicate exposure toextremely high levels (roughly 10 vol.%) may induce cardiac arrhythmias (irregularheartbeats) which may be serious or fatal.

N-HEXANE: Long-term or repeated exposure to n-hexane can cause peripheral nervedamage. Initial symptoms are numbness of the fingers and toes. Also, motor weaknesscan occur in the digits, but may also involve muscles of the arms, thighs and forearms. Theonset of these symptoms may be delayed for several months to a year after the beginningof exposure. Testicular atrophy and partial to full loss of the germ cell line were observed insub-chronic high-dose inhalation studies of laboratory rodents. These effects appearedirreversible. Rodent reproduction studies have shown evidence of reduced fetal weight butno frank malformations.

BUTANES: Studies in laboratory animals indicate exposure to extremely high levels ofbutanes (1-10 or higher vol.% in air) may cause cardiac arrhythmias (irregular heartbeats)which may be serious or fatal.

TOLUENE: Abuse of toluene at high concentrations (e.g., glue sniffing and solvent abuse)has been associated with adverse effects on the liver, kidney and nervous system, and cancause nervous system depression, cardiac arrhythmias, and death. Studies of workersindicate long-term exposure may be related to impaired color vision and hearing. Somestudies of workers suggest long-term exposure may be related to neurobehavioral andcognitive changes. Some of these effects have been observed in laboratory animalsfollowing repeated exposure to high levels of toluene. Several studies of workers suggestlong-term exposure may be related to small increases in spontaneous abortions andchanges in some gonadotropic hormones. However, the weight of evidence does notindicate toluene is a reproductive hazard to humans. Studies in laboratory animals indicatesome changes in reproductive organs following high levels of exposure, but no significanteffects on mating performance or reproduction were observed. Case studies of personsabusing toluene suggest isolated incidences of adverse effects on the fetus including birthdefects. Findings in laboratory animals have been largely negative. Positive findingsinclude small increases in minor skeletal and visceral malformations and developmentaldelays following very high levels of maternal exposure. Studies of workers indicate longterm exposure may be related to effects on the liver, kidney and blood, but these appear tobe limited to changes in serum enzymes and decreased leukocyte counts. Adverse effectson the liver, kidney, thymus and nervous system were observed in animal studies followingvery high levels of exposure. The relevance of these findings to humans is not clear at thistime.

BENZENE: Studies of workers exposed to benzene show clear evidence that overexposurecan cause cancer and other diseases of the blood forming organs including AcuteMyelogenous Leukemia (AML), and Aplastic Anemia (AA), an often fatal disease. Somestudies suggest overexposure to benzene may also be associated with MyelodysplasticSyndrome (MDS). Findings from a case control study of workers exposed to benzene wasreported during the 2009 Benzene Symposium in Munich included an increase in AcuteMyeloid Leukemias and Non-Hodgkins Lymphoid Neoplasms (NHLN) of the subtypefollicular lymphoma (FL) in some occupational categories. Some studies of workersexposed to benzene have shown an association with increased rates of chromosomeaberrations in circulating lymphocytes. One study of women workers exposed to benzenesuggested a weak association with irregular menstruation. However, other studies ofworkers exposed to benzene have not demonstrated clear evidence of an effect on fertilityor reproductive outcome in humans. Benzene can cross the placenta and affect thedeveloping fetus. Cases of AA have been reported in the offspring of persons severelyoverexposed to benzene. Studies in laboratory animals indicate that prolonged, repeatedexposure to high levels of benzene vapor can cause bone marrow suppression and cancerin multiple organ systems. Studies in laboratory animals show evidence of adverse effectson male reproductive organs following high levels of exposure but no significant effects on

reproduction have been observed. Embryotoxicity has been reported in studies oflaboratory animals but effects were limited to reduced fetal weight and minor skeletalvariations. Benzene has been classified as a proven human carcinogen by OSHA and aGroup 1 (Carcinogenic to Humans) material by IARC. The current proposed IARCclassification for benzene is summarized as follows: Sufficient evidence for Acute MyeloidLeukemia; limited evidence for Acute Lymphatic Leukemia, Chronic Lymphatic Leukemia,Non-Hodgkin Lymphoma, and Multiple Myeloma.

ETHYLBENZENE: Findings from a 2-year inhalation study in rodents conducted by NTPwere as follows: Effects were observed only at the highest exposure level (750 ppm). Atthis level the incidence of renal tumors was elevated in male rats (tubular carcinomas) andfemale rats (tubular adenomas). The incidence of tumors was also elevated in male mice(alveolar and bronchiolar carcinomas) and female mice (hepatocellular carcinomas). IARChas classified ethyl benzene as "possibly carcinogenic to humans" (Group 2B). Studies inlaboratory animals indicate some evidence of post-implantation deaths following high levelsof maternal exposure. The relevance of these findings to humans is not clear at this time.Studies in laboratory animals indicate limited evidence of renal malformations, resorptions,and developmental delays following high levels of maternal exposure with evidence ofmaternal toxicity. The relevance of these findings to humans is not clear at this time.Studies in laboratory animals have demonstrated evidence of ototoxicity (hearing loss)following exposure levels as low as 300 ppm for 5 days. Studies in laboratory animalsindicate some evidence of adverse effects on the liver, kidney, thyroid, and pituitary gland.

C9 AROMATIC HYDROCARBONS: A developmental inhalation study was conducted inlaboratory mice. Increased implantation losses, reduced fetal weights, delayed ossificationand an increased incidence of cleft palate were observed at the highest exposure level(1,500 ppm). This exposure level was extremely toxic to pregnant female mice (44%mortality). Reduced fetal body weights were also observed at 500 ppm. Amulti-generation reproduction inhalation study was conducted in laboratory rats.Reductions in pup weights, pup weight gain, litter size, and pup survival were observed at1,500 ppm, an exposure level at which significant maternal toxicity was observed. Reducedpup weight gain was also observed at 500 ppm.

COMBUSTION ENGINE EXHAUST: Chronic inhalation studies of gasoline engine exhaustin mice, rats and hamsters did not produce any carcinogenic effects. Condensates/extractsof gasoline engine exhaust produced an increase in tumors compared to controls whentesting by skin painting, subcutaneous injection, intratracheal instillation or implantation intothe lungs. Gasoline exhaust has been classified as possibly carcinogenic to humans (2B)by the International Agency for Research on Cancer (IARC).
