(IET) has prepared the following injection report. This report has been prepared to document remediation activities conducted at the site. The injection program was implemented from January 7th to 17th 2019. The remedial approach employed the oxidation remediation product "Ferric Oxide activated Persulfate". This product pairs a self -activating oxidation persulfate chemistry while providing the appropriate components for a longer lasting biological attenuation process following the initial oxidation event. The materials introduced across 19 of 20 injection wells included 158,858 pounds of sodium persulfate, 13,826 pounds of ferric oxide powder in approximately 69,536 gallons of solution. Although several attempts were made IW-16 was not installed due to obstacles encountered prior to reaching the desired depth. Surfacing of remedial material was encountered during the implementation of the design at several of the Injection Wells; namely (IW-1, IW-2, IW-3, IW-6, IW-7, IW-10, IW-11 and IW-13). Ultimately full dosages were applied to IW-3, IW-6 and IW-7 using decreased flow and pressure and revisiting the location multiple times. IW-1 and IW-2 were not completed in full, but 7 direct push locations were installed in the area around these two locations in order to distribute the material via injection. IW-10, IW-11 and IW-13 did not receive a full dosage but IW-12 received the materials left over from these wells. IW-12 is immediately upgradient of the uninstalled IW-16 location and 10, 11 and 13 were not accepting any more volume without excessive daylighting occurring in and along the road (Cullman Ave). IW-12 shares a screened interval with IW-13 so the extra material was added there. The point by point dosages along with instances of surfacing and other field notes are noted in the attached field logs. Introduction The Cullman Ave site located in Charlotte, NC, was identified as having soils and groundwater impacted by the historical release of chlorinated hydrocarbons. An injection program was conducted by IET for the remediation of CVOC impacts in both soil and groundwater throughout the designated areas utilizing advanced oxidation technologies. Remediation Implementation Injection Procedures IET injected a total of 19 injection wells and 7 direct push locations at the Cullman Ave. site. Details regarding each injection attempt are provided in the field logs in the Appendix. 2 1 P a g e Trex Properties — Cullman Ave. ePET Direct -Push -Driven Perforated Rod Placement A Powerprobe 9500 unit comparable to the one pictured in Figure 1, was utilized to drive the injection screen (as seen in Figure 2) to depths ranging from 5 to 27 feet below ground surface (bgs). It is at these depths, that the likelihood exists of being in close proximity to the targeted waters in the more permeable layers that were identified during FIGURE 1: AMS POWER PROBE 9500 VTR characterization of the site. These more permeable layers are those believed to have historically provided the preferential pathways taken by the dissolved -phase CVOCs. Subsurface Pathway Development Compressed air was used to propel all injectants - into the subsurface. Compressed air was first - injected into the subsurface at approximately 150 pounds per square inch (psi) until a significant pressure drop was observed at the injection pressure vessel. This process is referred to as pathway development. The intent of this step is to open pathways in the subsurface for FIGURE 2: RETRACTABLE INJECTION SCREEN the injectants to follow. These pathways are believed to be those more permeable pathways along which VOCs are more likely to have migrated, both in the vadose and saturated zones. Liquid and liquid -entrained injectants are then delivered with pressurized gas to the pathways that were produced during the development step. Liquid Injection A predetermined volume of the sodium persulfate and ferric oxide material was immediately injected into the subsurface fractures and voids that were developed during the compressed air injection step. Liquid Rinse A small amount of water was injected to clear the injection lines and sand packs of the injectant. Post Injection Line Purge Compressed air was injected to clear the lines of all material and to force the remedial components further into the formation before moving to the next injection location. 3 1 P a g e Trex Properties — Cullman Ave. QET Site Map e PMW ,W —9A Iw- \20 j SOURCE AREAFOR - GONTAMINAT10N ti 3A7 Lf o- uw c6 14' DPT Locations FIGURE 3: GENERAL INJECTION IMPLEMENTATION — INJECTION LOCATIONS 4111 c. Trex Properties — Cullman Ave. GET Conclusion The injection program at the Cullman Ave. site was implemented based on the proposed design with slight field modifications. All proposed injectants were introduced at the targeted depths. It is expected that the injection event will yield positive results and IET looks forward the assessing the data following future sampling events.

Brief description of business: Former RCRA TSD facility where solvents were recycled under the company name Detrex under a RCRA Part B Permit. VI. INCIDENT DESCRIPTION 1. Source and date of contamination: The facility was first permitted to recycle waste solvents (primarily PCE and TCE) in 1983 under the first RCRA Part B permit for such a facility in the state of NC. Over the years, incidental spills of such solvents resulted in contamination of unsaturated materials occurring beneath and adjacent to the on site buildings Over time the soil contamination gave rise to contamination of underlying groundwater. Solvent contaminated groundwater then migrated with natural groundwater flow to downgradient properties to the north and to a perennial stream known as Little Sugar Creek 2. List all contaminants present in soils or groundwater at the site (contaminants may be listed in groups, e.g., gasoline, diesel, jet fuel, fuel oil, chlorinated ethenes, chlorinated ethanes, metals, pesticides/herbicides, etc): Chlorinated ethenes and chlorinated ethanes 3.

As shown in Figure 2, the land surface topography rises sharply at the southern property boundary where the railroad lines are located, and slopes gently downward to the north towards Little Sugar Creek. Little Sugar Creek and associated tributaries are the primary surface water features in the immediate vicinity of the site. The northern boundaries of the subject properties are located approximately 150 feet to the south of Little Sugar Creek, which flows to the west towards downtown Charlotte. 1.2 GEOLOGY and HYDROGEOLOGY The site is located within a geologic terrain known as the Charlotte Belt, which is part of the Piedmont Physiographic Province. The topography of the Piedmont is commonly - characterized by low rounded hills and long northeast to southwest trending ridges with incised creek channels. The Charlotte Belt consists primarily of moderately metamorphosed coarse grained igneous rocks including granite, diorite and gabbro. The soil profile in the Piedmont is formed by the in -place chemical and physical weathering of the underlying rock. The most highly weathered materials occur near the land surface and typically contain appreciable amounts of clay generated through chemical alteration of feldspar minerals that are part of the parent rock. With increasing depth in the soil profile the degree of weathering and amount of clay minerals decreases and the appearance and texture of the soil begin to resemble those of the underlying parent rock. This material which has the appearance of rock but which is unconsolidated is known as saprolite. With increasing depth the saprolite becomes more consolidated until the point where it can no longer be penetrated by mechanical drilling machinery such as direct push equipment or hollow stem augers. Geologic material below this point is referred to as partially weathered rock (PWR), which is often the most permeable part of the soil profile. The PWR becomes more consolidated with depth and gradually transitions into fully consolidated bedrock. Rainfall that does not a) run off, b) get absorbed by plants, or c) evaporate, infiltrates the soil profile until it reaches the water table. Below the water table, all porous saprolite or PWR and fractures within underlying bedrock are saturated with groundwater. These Page 1 of 4 Trex Properties, Charlotte NC NCDEQ UIC Permit Application Attachment 2A saturated subsurface materials comprise the unconfined aquifer that underlies the site. The Geologic Map of North Carolina (1985) and descriptions of rock samples obtained from deeper well borings at the site by previous investigators suggest that the parent rock in the area is a meta -diorite, which is a coarse grained igneous rock that has been moderately metamorphosed. Rock of this type would be expected to weather into a typical Piedmont soil profile that coarsens with depth and that does not contain confining layers. Therefore horizontal layers that restrict the vertical movement of groundwater should not be present within the aquifer that underlies the site. The presence of fractures in the upper portion of bedrock in Piedmont settings in North Carolina is not uncommon and is to be expected. However, experience has shown that attempting to fully characterize the nature and extent of fractures under a site such as this would be a cost prohibitive'exercise of questionable value. Experience at this and other Piedmont sites has shown that the direction of groundwater flow through partially weathered rock and competent bedrock is controlled by hydraulic gradients, and that groundwater will move from areas of higher hydraulic head (groundwater at higher elevation) to areas of lower hydraulic head. This is true for flow through either porous or fractured media. Table 1 contains information on the construction of the permanent monitoring wells installed in the vicinity of the site, including which portion of the aquifer the well screen is set within (saprolite, PWR or bedrock). Table 2 contains depth to groundwater measurements and groundwater elevations at well locations that were accessible on September 22 and 23, 2015. The groundwater elevation data for the shallow wells screened within saprolite are plotted and contoured in Figure 4 to depict the direction of groundwater flow in the shallower portion of the aquifer. The -groundwater elevation data for wells screened within the PWR portion of the aquifer are plotted and contoured in Figure 5 to illustrate the direction of groundwater flow in the deeper portion of the aquifer. The positions of the groundwater elevation contours on both Figures 4 and 5 are very similar and both imply northerly directions of groundwater flow towards Little Sugar Creek, which makes intuitive sense and is consistent with previous determinations. The groundwater elevations shown in Table 2 and on Figures 4 and 5 indicate that the highest groundwater elevation in the saprolite/partially weathered rock portion of the aquifer was measured at PMW-2oA, and that highest groundwater elevation in the bedrock was measured at PMW-2oB. Therefore, we expect that groundwater flows away from this area towards the north and northwest as illustrated in Figures 4 and 5. Additionally, we would not expect Page 2 of 4 Trex Properties, Charlotte NC NCDEQ UIC Permit Application Attachment 2A groundwater occurring at lower elevations to flow towards the PMW-20 well pair as the hydraulic head relationship would not allow such flow. Little Sugar Creek is a perennial surface water feature that has been present at its current location for a very long time. The creek occupies the topographically lowest area between higher topographic elevations to the north and south. Water within the creek comes from surface water runoff from the north, south and east, and flows to the west towards the city of Charlotte. The creek is considered to be a perennial stream because it exhibits water flow throughout the year, even during dryer times of the year. Water present within the stream during dryer times comes from groundwater discharge from both north and south sides of the creek. The creek is the area where groundwater flowing southward from the north meets groundwater flowing northward from the south, as illustrated in the groundwater elevation contour maps discussed above. As shown in Table 2, the hydraulic head or groundwater elevation in the deeper portion of the aquifer at well pairs located proximal to Little Sugar Creek is higher than that in the shallow portion of the aquifer, which indicates the presence of an upward component of groundwater flow. This is the case at PMW-7A & B, PMW-8A & B, PMW-9A, B & C, PMW-1oA & B, PMW-12A & B, PMW-21A & B, and PMW-22A & B. The groundwater elevation measured in PMW-11A was higher than that in deeper well PMW-11B when the water levels were measured on September 22, 2015. However, when these wells were measured during the September 25, 2012 groundwater sampling event documented in Amec's April 5, 2015 Draft Interim Report Addendum, the water level in deeper well PMW-11B was 0.27 feet higher than that in PMW-11A, indicating the presence of an upward component of groundwater flow. Conversely, the hydraulic head in the shallow portion of the aquifer is higher than that in the deeper portion at locations that are distant from the creek, particularly PMW-1A & B, PMW-2A & B, and PMW-2oA & B. This is typical of recharge areas where there is a downward component of groundwater flow. Additionally, the absence of contaminants associated with the site in two sets of groundwater samples from off -site wells PMW-22A & B, which are located on the north side of the creek, indicates that Little Sugar Creek is acting as a barrier that prevents groundwater from south of the creek from moving further to the north. The concept that groundwater in the vicinity of the site is discharging into Little Sugar Creek is supported by previous analyses of surface water from the creek provided in Amec's 2012 Phase II Interim Report, which show detectable concentrations of contaminants in all samples collected at various locations along the creek. Page 3 of 4 Trex Properties, Charlotte NC NCDEQ UIC Permit Application Attachment 2A All of the lines of evidence described above imply that Little Sugar Creek acts not only as a groundwater discharge area, but as a hydraulic barrier that prevents the movement of groundwater from the south side of the creek to its north side, and vice versa. The geologic cross -sections provided in Figures 6 through 9 provide four different views of the subsurface, and variations in the approximate thickness of the saprolite and PWR across the area of investigation. The cross -sections also show the variations in the depth to competent bedrock across the site. In general, the depth to bedrock increases with proximity to Little Sugar Creek.

The purpose of conducting these tests was to provide a means of estimating the hydraulic conductivity of the saprolite, PWR and bedrock portions of the aquifer that underlies the site. The slug tests were performed in substantial accordance with the Procedures for Conducting and Analyzing Slug Tests dated November so, 2014 and its NCDENR approval letter dated November 25, 2014. The relatively rapid rate of water level recovery in the saprolite and PWR wells necessitated the use of a pressure transducer and data logger to obtain usable early test water level recovery data. As a QA/QC check, manual water level measurements were collected as the slug in and slug out test data were being measured and recorded by the pressure transducer and data logger at the saprolite and PWR well locations. The rate of water level recovery within bedrock well PMW-13B was slow enough to allow manual measurement of water level recovery data alone. Copies of field notes and photographs taken during the slug testing activities are provided in Appendix G. Pertinent test information and water level recovery data recorded by the data logger are included in Appendix H, as are the manual readings recorded at each well location. Calculations of hydraulic conductivity estimates from the test data are provided in Appendix I. 1.2 SLUG TESTING RESULTS Calculations of hydraulic conductivity estimates using monitoring well installation details and water level recovery data according to the method of Herman Bouwer (1989) are provided in Appendix H. The resulting hydraulic conductivity estimates for the saprolite, PWR and bedrock are summarized in Table 7. The average hydraulic conductivity for the saprolite was determined to be approximately 3.0 feet per day (ft/d) or about 1.1 x 10"3 centimeters per second (cm/s). The average hydraulic conductivity for the PWR was determined to be approximately 2.8 ft/d or about 9.8 x 10-4 cm/s, which is essentially equivalent to the average hydraulic conductivity of the saprolite. This hydraulic conductivity range is generally equivalent to that of a silty fine to medium sand that might be found in a coastal plain setting and suggests that the saprolite and PWR beneath the site would be amenable to injection of either high or low viscosity reagents formulated to reduce the concentrations of VOCs in groundwater. Page 1 of 2 Trex Properties, Charlotte NC NCDEQ UIC Permit Application Attachment 2E The average hydraulic conductivity of the bedrock at location PMW-13B (0.03 ft/d or 1.1 x io" 5 cm/s) was found to be two orders of magnitude lower than that of the saprolite and PWR. W&R expects that the range of bedrock hydraulic conductivity varies within ± one order of magnitude depending on the amount of fractures present at a given location. According to the cross -sections provided in Attachment 2A the combined thickness of the saturated saprolite and underlying PWR ranges between approximately 4o and 70 ft. Therefore, using an average hydraulic conductivity of 3 ft/day for these materials, the transmissivity of the unconfined surficial aquifer in the vicinity of the site should range between 14o and 210 ftZ/day. Because the surficial aquifer is unconfined, the storativity is equal to the specific yield, which is also known as the effective porosity (Fetter, 1980). According to grain size distribution analysis performed on a saturated soil sample obtained from a depth of 5 to 15 feet from temporary observation well OW-2, the sample contained about 62% sand, 30% silt and 8% clay.

Merril Publishing Company, Columbus Ohio, 488p. r Trex Properties, Charlotte NC NCDEQ UIC Permit Application Attachment 2F 1.1 Groundwater Flow Direction and Gradient According to the groundwater elevation contours for the shallower portion of the surficial aquifer shown in Figure 4 of Attachment 2A, the direction of groundwater flow is to the north and northwest, towards Little Sugar Creek. The horizontal hydraulic gradient between the south side of the Trex Property and Little Sugar Creek is approximately o.o1 ft/ft (5 ft of groundwater elevation change over an approximately 500 ft flow path). 1.2 Groundwater Flow Rate According to Fetter,198o the groundwater seepage velocity or flow rate is equal to the hydraulic conductivity of the aquifer times the horizontal hydraulic gradient, divided by the effective porosity. Using an average hydraulic conductivity of 3 ft/day and an effective porosity of 0.20 (discussed in Attachment 2E), and a horizontal hydraulic gradient of o.o1 ft/ft, the groundwater flow rate within the surficial aquifer should be approximately 0.15 ft/day, or about 55 ft/yr.

Contractor will be equipped with an all -terrain forklift to manage reagents and will store persulfate inside a large secondary containment berm near the work area. At the beginning of each injection day, contractor will park our custom-built injection vehicle (photos included) near the injection area. Persulfate will be brought to the area and stored adjacent to the injection vehicle. When injecting FeEDTA activated persulfate we simultaneously feed caustic and the persulfate at the same time. This provides for the best mixing of activator and oxidant. During injection all injection rates and pressures are recorded with pressure gauges and custom built digital turbine flow meters. Depending on expected flow rates, the appropriate size flow meter is selected. To also maintain consistent flows and pressures, a pressure relief valve ensure design injection pressures are not exceeded. The persulfate will be mixed in 500 gallons batches using 2000 lb super sacks and contractor's Bulk Mixing ISCO trailer (see photo below). Due to the corrosively of FeEDTA and persulfate all injection and mixing equipment will be either stainless steel, PVC or plastic tanks. PVC injection hose is also used due to its compatibility with caustic and persulfate and is usually pressure rated at < 250 PSI. During injection there is always a safety shower andpw _wash available and PPE includes Tyvek, Respirator when mixin , ggles and a face shield. sAll injection equipment is kept in secondary -�...�a. containment, and if it rairff prior to discharge of rain water it is tested for pH to ensure it hasn't been impacted by the persulfate or caustic. After injection distribution can be assessed through electrical conductivity loggings or sampling nearby wells for DO, ORP, pH, Conductivity, and persulfate concentration (test kit). Depending on the amount of contaminant mass in solid and groundwater, multiple injection events may be required to meet remediation expectations During injections, the persulfate solution will be manifolded to multiple locations to maximize efficiencies in the field. For well injections, contractor will utilize a PVC well cap fixed with a threaded cap to each location. Each well cap will be equipped with a pressure gauge and pressure relief valve. contractor will inject at up to four well locations simultaneously. CLIENTS estimates a flow rate per point of 5 gallons per minute (gpm) at less than 40 pounds per square inch (PSI) per well. Contractor assumes that all points will accept persulfate at these flows and pressures. If flows cannot be established or pressures cannot be maintained below 40 PSI resulting in additional time on site, this will be managed through a change order. Following set up, CTS will obtain water from a nearby fire hydrant using a backflow preventer and supply the bulk mixture. The City water will then be utilized as mix water in the persulfate injections.

The next set of groundwater samples will be collected approximately six months following completion of the injection. Another set of groundwater samples will be collected after six additional months, approximately one year following completion of the injection. Subsequent sets of groundwater samples will be collected on an annual basis. Groundwater samples from the wells listed will be analyzed for volatile organic compounds (VOCs), persulfate, total organic carbon (TOC), sulfate, iron, chloride, and ethenes. Additionally, the samples will be tested in the field for temperature, pH, specific conductance, dissolved oxygen and redox potential. Monitoring will also include making periodic observations of Little Sugar Creek during the injection process for any signs of injectant daylighting, and collection and testing of three surface water samples from Little Sugar Creek from upstream, midstream and downstream locations (see attached Figure 3). These samples will be collected on the same schedule as the groundwater samples. The surface water samples will be analyzed for VOCs by an EPA -certified laboratory. Additionally, the samples will be tested in the field for temperature, pH, specific conductance, Page i of 2 dissolved oxygen and redox potential. Laboratory analytical results for groundwater samples obtained from the site in 2012, 2014 and 2015 indicate that the VOCs tetrachloroethene (PCE), trichloroethene (TCE), cis 1,2 dichloroethene (DCE), 1,1 DCE, and 1,4 dioxane are present at the most groundwater monitoring locations at concentrations that exceed their North Carolina groundwater standards established in Title 15A of the North Carolina Administrative Code Subchapter 2L (2L Standards). For this reason, these five VOCs are considered to be the primary contaminants of concern present in groundwater in the vicinity of the site. Maps that show the horizontal distribution of these VOCs in groundwater are provided in Attachment 9. Cross -sections which show the vertical distribution of these VOCs are included in Attachment 1.

Disclaimer: The estimated dosage and recommended application methodology described in this document are based on the site information provided to PeroxyChem, but are not meant to constitute a guaranty of performance or a predictor of the speed at which a given site is remediated. Klozur® persulfate and activator demand calculations do not take into account the kinetics, speed of the reaction, or ability to establish contact between the reagents and contamination in the subsurface. These calculations represent the minimum anticipated amount needed to treat the constituents of concern (COCs). As a result, these calculations should be used as a general approximation for purposes of an initial economic assessment. PeroxyChem recommends that oxidant demand and treatability testing be performed to verify the quantities of oxidant needed. page 3 of 5 5/6/2016 Klozur Persulfate activation chemistries are used to convert Klozur Persulfate into the highly reactive radicals. Choosing the right activator chemistry for your contaminants of concern is important in obtaining a successful site remediation. The choice of activator will be dependent upon the target contaminants, site lithology and hydrogeology, and other site conditions. While activator demand quantities for all methods are given, not all activation methods are recommended for your given contaminant or site conditions. Please consult with an PeroxyChem Environmental Solutions technologist for proper selection of activation chemistry.

HAZARDOUS DECOMPOSITION PRODUCTS: Oxygen that supports combustion and oxides of sulfur. COMMENTS: PRECAUTIONARY STATEMENT: Pumping and transport of Klozur persulfate requires appropriate precautions and design considerations for pressure and thermal relief. Decomposing persulfates will evolve large volumes of gas and/or vapor, can accelerate exponentially with heat generation, and create significant and hazardous pressures if contained and not properly controlled or mitigated. Use with alcohols in the presence of water has been demonstrated to generate conditions that require rigorous adherence to process safety methods and standards to prevent escalation to an uncontrolled reaction. 11.

Irritating to eyes, respiratory system and skin. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ■ The material has NOT been classified as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence. <\p>. EYE ■ This material can cause eye irritation and damage in some persons. SKIN ■ This material can cause inflammation of the skin oncontact in some persons. ■ The material may accentuate any pre-existing dermatitis condition. ■ Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions. • Open cuts, abraded or irritated skin should not be exposed to this material. ■ Entry into the blood -stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ■ The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ■ Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled. CHRONIC HEALTH EFFECTS ■ Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis: caused by particles less than 0.5 micron penetrating and remaining in the lung. <\p>. Chelates are occasionally used in therapies for various forms of poisoning. A systemic reaction known as the "excessive chelation syndrome" consists mainly of general unwellness, fatigue, thirst, followed by chills and fever. <\p>. Injection of EDTA and it salts can cause severe kidney damage with tissue death and internal bleeding, bone marrow depression and critically low levels of calcium. Chronic excessive intake of iron have been associated with damage to the liver and pancreas. People with a genetic disposition to poor control over iron are at an increased risk. <\p>.

FIRE FIGHTING Alert Emergency Responders and tell them location and nature of hazard. Wear breathing apparatus plus protective gloves. GENERAL FIRE HAZARDS/HAZARDOUS COMBUSTIBLE PRODUCTS Combustible solid which burns but propagates flame with difficulty. Avoid generating dust, particularly clouds of dust in a confined or unventilated space as dusts may form an explosive mixture with air, and any source of ignition, i.e. flame or spark, will cause fire or explosion. Dust clouds generated by the fine grinding of the solid are a particular hazard. accumulations of fine dust may bum rapidly and fiercely if ignited. Combustion products include: carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx), metal oxides, other pyrolysis products typical of burning organic material. May emit poisonous fumes. May emit corrosive fumes. FIRE INCOMPATIBILITY ■ Avoid contamination with oxidizing agents i.e. nitrates, oxidizing acids,chlorine bleaches, pool chlorine etc. as ignition may result. PERSONAL PROTECTION Glasses: Chemical goggles. Gloves: Respirator: Particulate Section 6 - ACCIDENTAL RELEASE MEASURES MINOR SPILLS Clean up all spills immediately. Avoid breathing dust and contact with skin and eyes. MAJOR SPILLS ■ Moderate hazard. CAUTION: Advise personnel in area. Alert Emergency Responders and tell them location and nature of hazard. Section 7 - HANDLING AND STORAGE PROCEDURE FOR HANDLING Avoid all personal contact, including inhalation. Wear protective clothing when risk of exposure occurs. Empty containers may contain residual dust which has the potential to accumulate following settling. Such dusts may explode in the presence of an appropriate ignition source. Do NOT cut, drill, grind or weld such containers In addition ensure such activity is not performed near full, partially empty or empty containers without appropriate workplace safety authorisation or permit. RECOMMENDED STORAGE METHODS Polyethylene or polypropylene container. Check all containers are clearly labelled and free from leaks. STORAGE REQUIREMENTS Store in original containers.

Care must be taken, when removing gloves and other protective equipment, to avoid all possible skin contact. Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include: such as: frequency and duration of contact, chemical resistance of glove material, glove thickness and dexterity Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739). When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes according to EN 374) is recommended. When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according to EN 374) is recommended. Contaminated gloves should be replaced. Gloves must only be worn on clean hands. After using gloves, hands should be washed and dried thoroughly. Application of a non -perfumed moisturiser is recommended. Experience indicates that the following polymers are suitable as glove materials for protection against undissolved, dry solids, where abrasive particles are not present. polychloroprene nitrile rubber butyl rubber fluorocaoutchouc polyvinyl chloride Gloves should be examined for wear and/ or degradation constantly.

For incompatible materials - refer to Section 7 - Handling and Storage. Section 11 - TOXICOLOGICAL INFORMATION EDTA IRON SODIUM SALT TOXICITY AND IRRITATION ■ unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances. TOXICITY IRRITATION Oral (rat) LD50: 5000 mg/kg Nil Reported ■ Asthma -like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non -allergenic condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non-atopic individual, with abrupt onset of persistent asthma -like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production. Contact allergies quickly manifest themselves as contact eczema, more rarely as urticaria or Quincke's edema. The pathogenesis of contact eczema involves a cell -mediated (T lymphocytes) immune reaction of the delayed type. <\p> For ethylenediaminetetraacetic acid (EDTA) and its salts: EDTA is a strong organic acid (approximately 1000 times stronger than acetic acid). It has a high affinity for alkaline -earth ions (for example, calcium and magnesium) and heavy-metal ions (for example, lead and mercury). This affinity generally results in the formation of highly stable and soluble hexadentate chelate complexes. EDTA's ability to complex is used commercially to either promote or inhibit chemical reactions, depending on application EDTA and its salts are expected to be absorbed the lungs and gastrointestinal tract; absorption through the skin is unlikely. In general, EDTA and its salts are mild skin irritants but considered severe eye irritants. The greatest risk in the human body will occur when the EDTA attempts to scavenge the trace metals used and required by the body The binding of divalent and trivalent cations by EDTA can cause mineral deficiencies, which seem to be responsible for all of the known pharmacological effects. Sensitivity to the toxic effects of EDTA is, at least in part, related to the deficiency of zinc. Several short term studies, reported no adverse effects from administering doses up to 5% of EDTA and its salts to lab rodents daily and for several weeks. Only diarrhoea and lowered food consumption were reported in animals given 5% disodium EDTA. However, abnormal effects were seen in animals that were fed mineral deficient diets. Abnormal symptoms were observed in male and female rats fed a low mineral diet (0.54% Ce and 0.013%Fe) with the addition of 0%, 0.5%, or 1 % disodium EDTA for 205 days. Rats fed a low percent of disodium EDTA in the diet for short term studies with adequate minerals showed no signs of toxicity. Rats fed 0.5% disodium EDTA for 44-52 weeks were without deleterious effects on weight gain, appetite, activity and appearance. Rats fed 1 % disodium EDTA with adequate mineral diet for 220 days showed no evidence of dental erosion. EDTA and its salts are eliminated from the body, 95% via the kidneys and 5% by the bile, along with the metals and free ionic calcium which was bound in transit through the circulatory system 6 of 8 Trisodium EDTA was tested in a bioassay for carcinogenicity by the National Cancer Institute. Trisodium EDTA administered to male and female rats at low (3,750 ppm) or high (7,500 ppm) concentrations for 103 weeks produced no compound -related signs of chemical toxicity, and tumor incidence was not related to treatment . EDTA and its salts should not pose a teratogenic concern based on previous studies in lab rodents. Study results indicate no teratogenic effects are likely in lab rodents at doses up to 1000 mg/kg . Adequate minerals in the diet and administration of tap water prevented possible teratogenic effects of EDTA during pregnancy. Teratogenic effects observed in lab rodents were likely due to animals maintained on deionised water and a semi -purified diet, and housed in nonmetallic caging. Infants and children will unlikely be exposed to high concentrations as in lab rodents. Rats given 1250 mg/kg or 1500 mg/kg by gavage exhibited more maternal toxicity than the diet group, but produced only 21 % malformations in the offspring at the lower dose. The subcutaneously administration of 375 mg/kg was also maternally toxic, but did not result in malformations in the offspring. Differences in toxicity and teratogenicity are probably related to absorption differences and interaction with metals . Disodium EDTA ingested during pregnancy is teratogenic in rats at 2% in the diet and greater The maximum human consumption of EDTA and its salts in foods was reported to be on the order of 0.4 mg/kg/day. Infants and children also generally drink tap water instead of deionised or distilled water. Even if young infants were to be fed some solid food, given the characteristics of EDTA and its salts, residues are not likely to be present at concentrations for potential sensitivity.

Issue Date: Nov-23-2008 Print Date:Oct-22-2010 8of8 PeroxyChem K L O Z U R Klozur° Persulfate Demand Test and Base Buffering Capacity test Client: WithersRavenel 1410 Commonwealth Drive, Unit 101 Wilmington, NC 28403 Brian Bellis Phone: 910 — 256 — 9277 Email: bbellis@writhersravenel.com Performing Lab: PeroxyChem Environmental Solutions USA Tonawanda, New York Date May 4, 2016 Background Klozur® activated persulfate is a strong oxidant capable of mineralizing a wide range of contaminants, including chlorinated solvents, petroleum hydrocarbons, polyaromatic hydrocarbons, gasoline additives, pesticides, and many others. Activation of the persulfate anion generates the sulfate radical, the primary species that drives the rapid destruction of the contaminants of concern. Activation can be accomplished by several methods. heat, transition metals, addition of hydrogen peroxide, or utilizing high pH. Choice of the activation method will depend on the contaminant of concern and site characteristics. A chemical oxidant is not specific as to what it will oxidize. As a result, activated persulfate will not only mineralize the contaminant of concern, but a portion of the oxidant will be used in oxidizing soil organics, reduced metals, and organic species that are not of concern. In addition, activated persulfate will undergo auto -decomposition, which will be a function of temperature, concentration and activation method. The demand upon the activated persulfate from all of these components is captured in a coarse screening test termed, "Klozur Demand Test". It is dependent upon the site characteristics, such as the organic content of the soil, the mineral loading, and soil type and collectively must be considered for estimating the magnitude of oxidant dosing during field application. PeroxyChem is the owner of licensee under various patents relating to the use of activation chemistries PeroxyChem LLC Report page 1 of 5 May 4, 2016 The Klozur® Persulfate KDT test measures the loss of persulfate in the presence of soil, groundwater and activator over a period of 48 and 168 hours. The resulting KDT values can then be used as a guide to develop appropriate persulfate dosing for subsequent treatability testing and field applications. When high pH is chosen as a means of activation, a Base Buffering Capacity (BBC) test is recommended. The goal of a BBC test is to determine the amount of sodium hydroxide (NaOH) needed to raise the pH of a soil to pH 10.5, which is necessary for Klozur persulfate activation. This report contains the results and observations from both a KDT and BBC test. II.

Skin irritation Non -irritating to the skin LD50 Oral > 2000 mg/kg bw (rat) LD50 Dermal > 2000 mg/kg bw (rat) LC50Inhalation > 2.75 mg/L (4-hr) Sensitization Did not cause sensitization on laboratory animals Chronic toxicity Chronic toxicity In a 31/61-day oral study on rats with Ferric -sodium EDTA, the NOAEL >/= 84 mg/kg. Carcinogenicity Not recognized as carcinogenic by Research Agencies (IARC, NTP, OSHA, ACGIH) Mutagenicity Not mutagenic in AMES Test. Ferric sodium EDTA gave a positive response in the Mouse Lynphoma Assay (in vitro) with and without metabolic activation at concentrations that were cytotoxic. The positive response was attributed to a possible sensitivity of the cells to abnormal iron concentrations. Reproductive toxicity EDTA and its sodium salts have been reported, in some studies, to cause birth defects in laboratory animals only at exaggerated doses that were toxic to the mother. These effects are likely associated with zinc deficiency due to chelation. Exposures having no effect on the mother should have no effect on the fetus. Based on data with a related substance (magnesium-disodium EDTA), the NOAEL is expected to be 500 mg/kg. Target organ effects Skin, Eyes.

Current or future use of site with site contact person, address, and phone number. The Trex site at 3114 and 3124 Cullman Avenue in Charlotte, is currently vacant and unoccupied. The two buildings on the property are warehouse type structures each approximately 10, 000 square feet in size. Downgradient properties to the north are owned by Mecklenburg County and are vacant and unoccupied There are no buildings on these properties, and there are restrictions on the land use because the properties are in the flood plain of Little Sugar Creek. 3. Contractor applying product, contact person, address, and phone number. WithersRavenel, Inc. Brian Bellis, PG 1410 Commonwealth Drive, Suite 101, Wilmington NC 28403 910-256-9277 4. Distance and likelihood of impact to public or private wells used for drinking, industrial processes, cooling, agriculture, etc. Is area served by public water supply? Verification must be provided by the appropriate Regional Office of the Public Water Supply Section. The Trex site is located in a highly developed part of eastern Charlotte and pzrblic water is available throughout the area. According to the draft Phase I RCRA Facility Investigation Report prepared by MACTEC and dated March 23, 2009, there are no private or industrial wells within a 1, 500 foot radius of the site. This was determined by a visual survey and through review of'the Mecklenburg County GIS and the Mecklenburg Couivy Land Use and Environmental Services Agency. 5. General description of the contaminants if present in the soil and/or groundwater at the site. Volatile organic compounds (VOCs). Mainly, trichloroethene, tetrachloroethene, 1,1 dichloroethene, 1,1,1 trichloroethane and 1, 4 dioxane. 6. Name, approximate distance, and likelihood of impact to the nearest body of surface water to the site. Little Sugar Creek is located approximately 150, feet north of the Trex property. Analysis of 'sur face water samples_ from the creek indicate the presence of VOCs. Revised: Oct/13/2014 GW/UIC-3 RISK ASSESSMENT EVALUATION OF GROUNDWATER OR SOIL REMEDIATION ADDITIVES CONTAINING NO MICROORGANISMS Page 2 of 4 7. Approximate distance to nearest residence(s) and workplace. According to the 2009 report by MACTEC referenced previously; the area within about 1, 000, feet of the Trex site is coned industrial, and the nearest residential neighborhoods are about 1,000 to 1,200 feet to the northeast and southwest. The nearest occupied workplaces are adjacent to the Trex site to the west. Required Product/Process-Specific Information 1. Product manufacturer name, address, phone number, and contact person. PeroxyChem, LLC 1735 Market Street, Philadelphia, PA 19103. Contact: Patrick Hicks, PhD (919) 280-7962. 2. Identity of specific ingredients (including CAS#) and concentrations of ingredients contained in the product and purpose of each.* Ferric sodium EDTA: Chemical name: Ethyldiaminetetraacetic acid, ferric sodium complex C10H12FEN208Na.3H2O. Purposes: Chelating agent; plant nutrient: activator of sodium persulfate injectant. 3. Approximate concentration of each ingredient following release into groundwater or soil. According to Patrick Hicks of PeroxyChem, a Fe EDTA concentration of 200 parts per million is required to activate sodium persulfate injectant. Revised: Oct/l 3/2014 GW/UIC-3 RISK ASSESSMENT EVALUATION OF GROUNDWATER OR SOIL REMEDIATION ADDITIVES CONTAINING NO MICROORGANISMS Page 3 of 4 4. Approximate distance and direction of travel for product in groundwater, the groundwater concentration of each ingredient at this distance, and distance from this point to the nearest drinking water source (that is currently used for drinking purposes). These should be reasonably accurate estimates based on the best available information and calculations (modeling, if necessary) regarding aquifer characteristics and flowpaths at the site; where uncertainty exists in critical aquifer parameters (e.g. effective porosity), conservative assumptions should be made in estimating these values so that worst -case predictions of travel distances are made. According to the results of a clean water injection pilot test conducted within the injection zone near well PAIi- 5.4, we expect the sodium persulfate injectant and activator (Fe EDTA) to travel approximately 40 feet from each of the 20 injection wells. The natural groundwater seepage velocity is approximately 60 feet per year and flow direction is northerly towards Little Sugar Creek. There are no drinking water wells within 1,500 feet of the site. The Fe EDTA activator will be prepared and injected at a concentration of 200 parts per million. Approximate groundwater concentration of each ingredient after pumping or recovery (if applicable). Not applicable. 6. If the product is expected to discharge to a nearby surface water, approximate concentrations of product in the water. Product is not expected to discharge to nearby surface water. It will have been chemically consumed in its interaction with sodium persulfate and will leave only iron oxide as a byproduct of the reaction. 7. Documentation from authoritative technical references of specific degradation products expected. (Provide a brief summary of the referenced material as well as a copy of the referenced material.) See attached Material Safety Data Sheet for Dissolvine E-FR-13 (Fe EDTA). According to this document under the heading "Persistence and Degradability" the product is inherently biodegradable. EDTA ferric sodium complex is photodegradable with a half life of 20 days, and bioaccumulation is unlikely. Documentation from authoritative technical references of expected migratory potential of specific ingredients and degradation products in soil and groundwater. (Provide a brief summary of the referenced material as well as a copy of the referenced material.) According to Pat Hicks o f PeroxyChem, iron migratory potential is expected to be negligible because the main byproduct of'the reaction between sodium persulfate and Fe EDTA is oxidized iron, which will likely adhere to soil particles that comprise the aquifer. 9. Complete description of the use of the product at the site. Powdered Fe EDTA activator will be mixed with water in a lank on -site to a concentration of 200 parts per million. The powdered sodium persulfate injectant trill be Revised: Oct/13/2014 G W/U1C-3 RISK ASSESSMENT EVALUATION OF GROUNDWATER OR SOIL REMEDIATION ADDITIVES CONTAINING NO MICROORGANISMS Page 4 of 4 mixed with water in a separate tank, and will be injected simultaneously with the Fe EDTA activator solution. This will cause the production of persulfate radicals, which will oxidize the VOCs in groundwater leaving water, carbon dioxide and chloride as reaction byproducts. r- * If the composition of the proposed injected fluid is considered a trade secret and needs to be treated as confidential, please submit the confidential information clearly labeled as confidential. In addition, include a letter identifying the confidential information and stating why the information should be processed as confidential. All information warranting protection as a trade secret will be kept from public disclosure in accordance with G.S. 132- 1.2. and 15A NCAC 2C .0211(g). The risk assessment will be forwarded to the designated contact person for the site, consultant applying the product, and Division of Water Resources UIC Program contact person.

With regard to having monitoring wells outside the injection zone, we believe that existing monitoring well clusters PMW-8A & 86, and PMW-9A, 9B & 9C will serve this purpose. As we discussed on the phone, there is little room between existing wells PMW-10A & 10B and PMW-11A 11B and the slope that leads to Little Sugar Creek where additional downgradient monitoring wells could be installed. Our monitoring plan includes collection and analysis of surface water samples from Little Sugar Creek, which has already been impacted by VOCs from the Trex site and other upstream and downstream sites not related to Trex. Monitoring of the creek water downgradient of the injection area should allow us to evaluate the effectiveness of the injection. Regarding the groundwater seepage velocity: The average hydraulic conductivity for the shallow portion of the surficial aquifer determined from slug tests conducted in shallow wells PMW-1A and PMW-10A was 3.0 ft/day (see attachment 2 of our application). The hydraulic gradient for the shallow portion of the aquifer shown in Figure 4 of attachment 2 is approximately 0.011 (-4 feet of head drop over a distance of about 350 feet). The effective porosity of the surficial aquifer was determined from grain size analysis of a saturated soil sample and the method of Johnson (see attachment 2 of our application) is about 20%. Therefore the seepage velocity in the shallow portion of the aquifer is 3 ft/d x 0.011 divided by 0.2 is approximately 0.165 ft/day or about 60 ft/yr. The hydraulic conductivity of the deeper portion of the surficial aquifer was determined from slug tests conducted in deep wells PMW-1B and PMW-10B, and was very similar to that of the shallow portion of the aquifer (2.8 ft/d as shown in Table 7 of attachment 2). The hydraulic gradient for the deeper portion of the aquifer was determined from the groundwater elevation contours shown in Figure 5 of attachment 2 and is approximately 0.0105 (-4 feet of head drop over a distance of about 380 ft). Using an effective porosity of 20% for this similar material gives a seepage velocity of 2.8 ft/d x 0.0105 divided by 0.2 or 0.147 ft/day or about 54 ft/yr, which is very similar to that in the upper portion of the aquifer. `Thanks for your preliminary review or our application and for the opportunity to respond accordingly.

FORM: WQROS-ARR ver. 092614 Page 1 of 1 North Carolina Department of Health and Human Services Division of Public Health Roy Cooper Mandy Cohen Governor Secretary Daniel Staley Division Director February 20, 2017 MEMORANDUM To: Michael Rogers — UIC Program Aquifer Protection System Division. of Water Quality Department of Environment and Natural Resources From: Kennedy Holt Epidemiology Section Division of Public Health Department of Health and Human Services Subject: Health Risk Assessment Use o A o 'Remediation of Groundwater Contaminated with VOCs. This review is provided in response to a request for a health risk evaluation regarding the use of Fe EDTA for remediation of groundwater contaminated with VOCs. The contractor, Withers & Ravenel, Inc., is seeking approval for the use of Fe EDTA for underground injection remediation projects in conjunction with sodium persulfate in North Carolina. Based upon the supplied information from Withers & Ravenel, Inc. and PeroxyChern, it is unlikely that injections of Fe EDTA would affect neighboring wells or migrate through the aquifer. However, increases in chloride concentrations in groundwater may occur because of using this product_ This potential increase warrants the necessity of monitoring the remediation sites and wells surrounding these sites to ensure that chloride levels do not exceed the 250mg/L North Carolina 15A 02L .0202 groundwater standards. Additional site information would be in the Underground Injection Control (UIC) program product application worksheet. www.ncdhhs.gov Tel 919-707-5900 e Fax 919-870-4807 Location: 5505 Six Forks Road o Raleigh, NC 27609 Mailing Address: 1912 Mail Service Center • Raleigh, NC 27699-1912 �o An Equal Opportunity / Affirmative Action Employer Fe EDTA is composed of 87-89% of EDTA ferric sodium complex (CAS No. 15708-41-5) and 11- 0% Water (CAS No. 7732-18-5). Fe EDTA will be delivered to the remediation site in powdered form. This mixture will then be mixed on site, with water, to create an injection slurry with a concentration of 200 parts per million (ppm). This slurry will then be simultaneously injected with the sodium persulfate solution into the injection site. The following information is provided regarding precautions for handling and transporting the Fe EDTA powder: 1. Store in a cool, dry place. Fe EDTA readily absorbs moisture from the air. Additionally, thermal decomposition can lead to the formation of toxic gases and vapors. Nitrogen oxides (NOx), Carbon oxides (COx), and metal oxides can form in temperatures exceeding 25°C. 2. Health Hazards for Fe EDTA product: Exposure Routes: Inhalation, ingestion, skin and/or eye contact Target Organs: Eyes, skin, respiratory system Exposure Symptoms: Irritation to the eyes, skin, nose, and/or throat Eyes: If this product contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids for at least 15 minutes. Contact lenses should not be worn when working with this product. Skin: If this chemical contacts the skin, brush away the excess solids then wash with warm water and soap. Breath: If a person breathes large amounts of this product, contact the Poison Control Center, or notify a doctor. Swallow: If this product has been swallowed, do not induce vomiting. Provide water to rinse the mouth followed by water to drink to the individual. Contact the Poison Control Center or notify a doctor if in - doubt. 4. Personal Protective Equipment (PPE): • Wear appropriate personal protective clothing to reduce exposure to the skin and mitigate inhalation exposures. PPE should include chemical goggles, gloves (nitrile rubber), closed toed shoes, dust mask, and clothing to cover arms and legs: The worker should brush the solids off skin when it becomes contaminated. • Wear appropriate eye protection to prevent eye contact. Contact lenses should not be worn when working with this product. Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. 5. For the Fe EDTA product a N95 dust respirator should be used when working with this product to reduce inhalation exposures. Page 2 of 3 6. If anything more than a dust mask is required during work; then all exposed workers would need to be in a respiratory protection program that meets the OSHA respirator standard 29cfr 1910.134. So even if there are respirators there for emergencies or for escape the full OSHA respiratory standard is applicable. cif employees use just N95 dust masks voluntarily then only certain parts of the respiratory protection program are applicable. 7. First Aid EYE EXPOSURE - Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. DERMAL EXPOSURE — Wash with warm water and soap. Wash contaminated clothing before reuse. J INHALATION EXPOSURE — Move to a well -ventilated area with fresh air. If difficulty breathing or discomfort occurs, contact the Poison Control Center, or notify a doctor. ORAL EXPOSURE - If this product has been swallowed, do not induce vomiting. Provide water to rinse the mouth followed by water to drink to the individual- Contact the Poison Control Center or notify a doctor if in doubt. 8. Byproduct Concerns Chloride is an EPA Secondary Drinking Water Standard, as well as a NC North Carolina 15A 02L .0202 groundwater standard set at 250mg/L. Any entity seeking to use Fe EDTA as part of their groundwater remediation plan need to take the proper precautions to ensure that chloride levels do not exceed 250rng/L for the remediation site and for surrounding wells. This could be accomplished through the testing of groundwater from the remediation site and surrounding wells or through the construction of monitoring wells. Other recommendations: 9. Store and use in well ventilated areas_ 10. All persons involved in the handling and use of the product should be familiar with the information in this document and the MSDS. 11. Measures should be taken to prevent contamination of this product to nearby wells and surface water bodies, and to control the movement of the primary chemicals or reaction products offsite.

SODIUM PERSULFATE HEALTH RISK INFORMATION: Formula: Na2S203 CASN: 7775-27-1 Synonyms: Sodium peroxydisulfate, Sodium persulfate Classification: strong oxidant Sodium persulfate is a strong oxidant and reacts with combustible and reducing materials. Sodium persulfate decomposes on heating producing toxic and corrosive fumes including sulfur oxides. It reacts violently with powdered metals and strong bases. In solution in water it is a weak acid. Sodium persulfate becomes unstable when exposed to heat, moisture and/or contamination. It is incompatible with acids, alkalis, halides (fluorides, chlorides, bromides and iodides), combustible materials, most metals and heavy metals, oxidizable materials, other oxidizers, reducing agents, cleaners, and organic or carbon containing compounds. Oxidizing chemicals, including sodium persulfate, should not be stored or directly mixed with combustible material (such as fuels, papers or solvents) or reducing agents (such as metals or sulfites). Contact with incompatible materials can result in a material decomposition or other uncontrolled reactions. Oxidizing chemicals may react energetically with combustible materials or reducing agents and also release oxygen and heat during decomposition that could help support a fire. Some oxidizing agents are incompatible with one another. Decomposing persulfates will evolve large volumes of gas and/or vapor, can accelerate exponentially with heat generation, and create significant and hazardous pressures if contained and not properly controlled or mitigated. Use with alcohols in the presence of water has been demonstrated to generate conditions that require rigorous adherence to process safety methods and standards to prevent escalation to an uncontrolled reaction. Potential health effects: The primary route of toxicity is through direct inhalation of airborne dust or mist, or direct contact. Airborne persulfate dust may be irritating to eyes, nose, lungs, throat and skin upon contact. Dust dispersion should be controlled. Sodium persulfate in identified as a strong oxidizer and an irritant. Inhalation of dust may cause asthma -like reactions. Acute (short-term) health effects that may occur immediately or shortly after exposure include severe skin and eye irritation and burns. Breathing sodium persulfate can irritate the nose, throat and lungs, causing coughing, wheezing and/or shortness of breath. Long-term (chronic) or repeated exposure may cause a skin allergy or dermatitis. If allergy develops, very low future exposure can cause itching and a skin rash. An asthma -like allergy may also result from long-term or repeated inhalation exposures with future exposure potentially causing asthma attacks with shortness of �L OirlYo„ u, rU o� Location: 5505 Six Forks Rd., 2"d Floor, Room 1-2-DI - Raleigh, NC. 27609 :y�;�An Equal Opportunity Employer Page 3 of 9 breath, wheezing, cough, and/or chest tightness. General allergic reactions, like urticaria (hives) or shock, may occur. Sodium persulfate has not been tested for its ability to cause cancer or reproductive effects. Evidence of exposure includes: Inhalation: cough, labored breathing, sore throat, wheezing Skin: redness, pain Eyes: redness, pain Ingestion: diarrhea, nausea, sore throat, vomiting Recommended personal protective equipment (PPE): Prevent release of dust into the work environment with room ventilation. All persons working with sodium persulfate should use appropriate PPE, including: Eves and face: Use cup type chemical goggles. Full face shield may be used. Respiratory: Use approved dust respirator when airborne dust is expected. A NIOSH 100 HEPA tight -fitting half -face unit is recommended (with fit testing). Protective clothing: Normal work clothes. Rubber or neoprene footwear. Gloves: Rubber or neoprene gloves. Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for leaks. First Aid: Eye contact: Immediately flush with large amounts of water for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. Skin Contact: Quickly remove contaminated clothing. Immediately wash contaminated skin with large amounts of soap and water. Breathing: Remove the person from exposure. Begin rescue breathing (using universal precautions) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. Additional safety recommendations: Prevent release of dust into the work environment with room ventilation. Workers whose clothing has been contaminated with sodium persulfate should change into clean clothing promptly. On skin contact immediately wash or shower to remove the chemical. Remove contaminated clothing immediately and wash before reuse. At the end of the work shift, wash any areas of the body that may have contacted sodium persulfate, whether or not known skin contact has occurred. Do not take contaminated work clothes home to prevent exposure of family members. Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to sodium persulfate. Eye wash fountains should be provided in the immediate work area for emergency use. If there is the possibility of skin exposure, emergency shower facilities should be provided. Do not eat, smoke, or drink where sodium persulfate is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet. Handling and storage: Use adequate ventilation when transferring product from bags or drums.

Spills should be collected into suitable containers to prevent dispersion into the air. Wear respiratory protection if ventilation is inadequate or not available. Use eye and skin protection. Use clean plastic or stainless steel scoops only. Store (unopened) in a cool, clean, dry place away from point sources of heat, e.g. radiant heaters or steam pipes. In case of fire or decomposition (fuming/smoking) deluge with plenty of water to control decomposition. Use a vacuum or a wet method to reduce dust during clean-up. DO NOT DRY SWEEP.. CALCIUM PEROXIDE HEALTH RISK INFORMATION: Formula: Ca02 CASN: 1305-79-9 Synonyms: calcium dioxide, calcium superoxide, Calper, Calper G Classification: oxidizer Calcium peroxide is an oxidizer, thus contact with combustible materials (paper, cotton, organics, leather, reducing agents, and other oxidizers) should be avoided. Calcium peroxide is not flammable but will contribute oxygen to feed a fire. Contamination, heat, and humid conditions will enhance and accelerate decomposition. Decomposition is endothermic, unlike most oxidizers. Store calcium peroxide in a clean, dry place. Do not expose to heat sources or high humidity. Store away from combustible materials. Keep containers closed when not in use. Dilute spills with water. Potential health effects: Contact can severely irritate and burn the skin and eyes with possible eye damage. Breathing calcium peroxide can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Harmful if swallowed. The following acute (short-term) health effects may occur immediately or shortly after exposure. Contact can severely irritate and burn the skin and eyes with possible eye damage. Breathing calcium peroxide can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Chronic (long-term) health effects can occur at some time after exposure and can last for months or years and include lung irritation. Repeated exposure may cause bronchitis with cough, phlegm, and/or shortness of breadth. Calcium peroxide has not been tested for its ability to cause cancer or reproductive effects. Calcium peroxide should be handled in well ventilated, dust controlled areas. When handling large quantities, use a dust mask, goggles, and gloves. Evidence of exposure includes: Inhalation: nose and throat irritation Skin: irritation Eyes: irritation Ingestion: irritation of mouth and stomach Recommended personal protective equipment (PPE): Avoid skin contact with calcium peroxide.

Use a vacuum or a wet method to reduce dust during clean-up. DO NOT DRY SWEEP_ Handling and storage: Calcium peroxide must be stored to avoid contact with combustibles; hydrocarbons; fuels; cellulose; hydrogen peroxide; and organic materials since fires may occur.

SODIUM HYDROXIDE HEALTH RISK INFORAMTION: Formula: NaOH CASN: 1310-73-2 Synonyms: Caustic soda, Lye, Soda lye, Sodium hydrate Classification: alkaline, corrosive �� Location: 5505 Six Forks Rd., 2id Floor, Room 1-2-D1 • Raleigh, N.C. 27609 �,PI :■.o.�� •�'� An Equal Opportunity Employer Page 6 of 9 Sodium hydroxide is classified as a corrosive material. Sodium hydroxide is incompatible with water, acids, flammable liquids, organic halogens, organic peroxides, metals such as aluminum, tin, zinc, or nitromethane. It is corrosive to metals. Keep this compound separated from acids, easily ignitable materials, explosives, metals, organic peroxides, and water or any moisture. Sodium hydroxide will react with water to release heat and contact with aluminum, tin, lead and zinc will release flammable and explosive hydrogen gas. Contact with nitromethane and other nitro compounds may result in the formation of shock -sensitive or explosive salts. Contact with moisture or water may generate sufficient heat to ignite combustible substances. Potential health effects: Sodium hydroxide is a corrosive irritant of the skin, eyes, and mucous membranes. Sodium hydroxide both in solid and in solution has a markedly corrosive action upon all body tissues causing burns and frequently deep maceration, with ultimate scarring. Inhalation of the dust or concentrated mist can cause damage to the upper respiratory tract and to lung tissue, depending upon the severity of the exposure. Effects of inhalation may vary from mild irritation of the mucous membranes at 2 mg/m3 to severe pneumonitis at higher airborne concentrations. Inhalation of alkaline vapors can produce upper airway edema, respiratory failure, wheezing, pulmonary edema, and pneumonitis. Exposure to the dust or mist may cause pain, redness, irritation or full thickness burns. Contact with the eyes causes disintegration and sloughing of conjunctival and corneal epithelium, corneal opacification (renders the cornea opaque), marked edema, and ulceration. Permanent visual loss may occur. After 7 to 13 days, either gradual recovery begins, or there is progression of ulceration and corneal opacification. On the skin, solutions of 25 to 50% sodium hydroxide cause a sensation of irritation within about 3 minutes; with 4% solutions, irritation does not develop for several hours. If it is not removed from the skin, severe burns with deep ulceration may occur. Produces severe abdominal pain, corrosion of the lips, mouth, tongue, esophagus, and pharynx, and the vomiting of large pieces of mucosa. It can cause perforation and scarring. Glottic edema and upper airway obstruction may occur following ingestion. Cases of squamous cell carcinoma of the esophagus have occurred with latent periods of 12 to 42 years after ingestion. These cancers were the sequelae of tissue destruction and possible scar formation, rather than due to a direct carcinogenic action of sodium hydroxide itself. The greatest industrial hazard is rapid tissue destruction of eyes or skin upon contact with either the solid or concentrated solutions. Acute (short-term exposure) health effects which may occur immediately or shortly after exposure include with contact severe irritation and burning the skin and eyes with possible eye damage or clouding of the eyes with loss of vision. Breathing sodium hydroxide can irritate the mouth, nose and throat. Breathing can also irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. Chronic (long-term exposure) health effects can occur at some time after exposure to and can last for months or years. Very high chronic exposure may cause lung damage. Sodium hydroxide has not been tested, for ability to cause cancer in animals. There is no evidence it effects reproduction.

OSHA: The legal airborne permissible exposure limit (PEL) is 2 mg/m3 averaged over an 8-hour work shift. NIOSH: The recommended airborne exposure limit is 2 mg/m3, which should not be exceeded at any time. The NIOSH IDLH value is 10 mg/m3. ACGIH: The recommended airborne exposure limit is 2 mg/in3, which should not be exceeded at any time. Recommended personal protective equipment (PPE): Appropriate, impervious, protective clothing (including gloves) should be worn to prevent skin contact. Protective equipment should not be made of aluminum, copper, soft iron, tin, or zinc (or alloys made of these metals. Eyes and face: For solid sodium hydroxide wear impact resistant eye protection with side shields or goggles. For liquids wear indirect -vent, impact and splash resistant goggles. A face shield along with goggles is recommended when working with corrosive, highly irritating or toxic substances. Contact lenses should not be worn when working with this substance. Eyewash fountains should be provided. Respiratory: Use NIOSH certified toxic.dust"respirator. A NIOSH 100 HEPA tight- fitting half -face unit is recommended (with fit testing). Where the potential exists for exposure over 2 mg/m3, use a MSHA/NIOSH approved supplied -air respirator with a full face piece operated in a pressure -demand or other positive -pressure mode. For increased protection use in combination with an auxiliary self-contained breathing apparatus operated in a pressure -demand or other positive -pressure mode. Exposure to 10 mg/m3 is immediately dangerous to life and health. If the possibility of exposure above 10 mg/m3 exists, use a MSHA/NIOSH approved self-contained breathing apparatus with a full face piece operated in a pressure -demand or other positive -pressure mode. Gloves: Impervious. ACGIH recommends polyvinyl chloride, butyl, butyl/neoprene, natural rubber, neoprene, polyethylene, Saranex, Teflon and Viton/neoprene as protective materials. First Aid: Eyes: Irrigate immediately Skin: Water flush immediately. Clothing which becomes significantly contaminated, or wet, should be removed as quickly as possible. Breathing: Respiratory support Ingestion: Medical attention immediately Location: 5505 Stt Forks Rd., 2 t Floor, Room 1-2-D/ • Raleigh, N.C. 27609 - An Equal Opportunity Employer i�u,,�u uur Page 8 of 9 Handling and storage: Store in tightly closed containers in a cool, dry, well -ventilated area away from moisture. Wherever sodium hydroxide is used, handled, manufactured, or stored, use explosion -proof electrical equipment and fittings. Keep sodium hydroxide separated from acids, easily ignitable materials, explosives, metals, organic peroxides, and water (or any moisture). Additional safety recommendations: Workers whose clothing has been contaminated by sodium hydroxide should change into clean clothing promptly. Do not take contaminated work clothes home. Family members could be exposed. Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to sodium hydroxide. Eye wash fountains should be provided in the immediate work area for emergency use. If there is the possibility of skin exposure, emergency shower facilities should be provided. On skin contact sodium hydroxide, immediately wash or shower to remove the chemical. At the end of the work shift, wash any areas of the body that may have contacted sodium hydroxide, whether or not known skin contact has occurred. Do not eat, smoke, or drink where sodium hydroxide is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet.
