(Southern States) stating that excessive concentrations of nitrate and/or nitrite (as nitrogen) were detected in ground water at the Southern States Fertilizer Plant (NCDEHNR Groundwater Incident No. 5038). Canonie Environmental Services Corp. (Canonie) submits this Corrective Action Plan (CAP) to the NCDEHNR on behalf of the site owner, Southern States. Law Environmental, Inc. (Law) has provided assistance in preparation of this CAP as a special consultant to the site owner. It is being submitted for the Southern States Fertilizer Plant located in Statesville, Iredell County, North Carolina. The purpose of this CAP is to describe measures proposed to remediate ground water impacted with nitrates and nitrites at the Statesville Facility in response to the Notice of Violation. 1.1 Background The Southern States Fertilizer Plant is located on U.S. Highway 70 approximately six miles east of Statesville, North Carolina (See Figure 1). The facility was reportedly constructed in the 1950s. Southern States purchased the plant in February 1988. Various farm and garden fertilizers are manufactured at the plant using raw materials brought in by truck and rail. The materials are usually off-loaded directly onto conveyor belts for transfer to storage areas within the plant. Finished products are warehoused on -site pending shipment. Small warehouse areas at the north end of the main plant and a small building just east of the main plant are also used to store pre- mixed, bagged products on pallets. These products are sold directly to consumers without modification by Southern States. PR\W:\81-161\CAP [Jan. 31, 19941 CanonleEnviro=ental 2 The manufacturing facility air scrubber water system is currently self-contained; process water is recirculated within the plant without exterior discharge. Air scrubbers are used to reduce smokestack emissions. The scrubbers use a "wet" system and the scrubber water is consumed in the granulation process. Prior to changes in scrubber design approximately 12 years ago, process water was discharged from time to time. Drainage was to two holding ponds formerly located approximately 1,000 feet southwest of the plant. These ponds were closed in May 1992. Another pond located due east of the plant was closed approximately 20 years ago, and another one, located 300 feet southeast of the plant, was closed 7 to 8 years ago. Modifications to plant processes have been implemented over the last several years, so that waste products are appropriately contained within the manufacturing facility. 1.2 Previous Site Investigations In September 1989, Southern States retained Law Environmental (Law) to assist with evaluation and remediation efforts at the Statesville Fertilizer Plant. On December 12, 1989, NCDEHNR issued a Notice of Violation for the site. The notice stated that excessive concentrations of nitrate and/or nitrite (expressed as nitrogen) had been discovered in two NCDEHNR wells (K65W6 and K65W7) at the site (See Figure 2 for well locations). Nitrate/nitrite concentrations, were greater than the threshold values of 10 milligrams/liter (mg/1) nitrate/1 mg/I nitrite set forth in Title 15, Subchapter 2L, Section .0202(g) of the North Carolina Administrative Code (15A NCAC 2L). The notice required submission of specific technical and field data documenting the ground water conditions within 60 days. On January 19, 1990, representatives of Southern States and Law met with the NCDEHNR. All parties agreed that six ground water monitoring wells would be constructed at the site. Two of the monitoring wells would be extended to bedrock (defined as auger refusal) and four would be shallow monitoring wells .intended to address the lateral extent of contamination. This initial well installation work, referred to as Phase I, was conducted during the period of January 30 through February 7, PR%W:%91-1611CAP [Jon. 31, 1994] CanonleEnviro=ental 3 1990 and reported by Law as a response to the Notice of Violation. Additional ground water assessment was recommended. On May 4, 1990, the NCDEHNR issued a letter to Southern States. The letter indicated that the NCDEHNR Mooresville Regional Office had reviewed Law's Phase I Ground Water Assessment Report for the Statesville Southern States Fertilizer Plant. The letter stated that NCDEHNR was in agreement with Law concerning the need for further assessment activities. NCDEHNR indicated that these activities should be designed to more fully define the vertical and horizontal extent of nitrate/nitrite as nitrogen constituents in ground water at the site. Specifically, NCDEHNR suggested six points for consideration during a recommended Phase 11 assessment. A June 15, 1990 submittal was prepared by Law to respond to the May 4, 1990 letter from NCDEHNR. The submittal also contained a proposed Phase II Ground Water Assessment Work Plan designed to address the six points outlined by NCDEHNR. Phase II ground water assessment activities were completed and a Phase II Ground Water Assessment Report was submitted to NCDEHNR on September 25, 1990. Analytical results from Phase II analyses indicated that subsurface nitrate/nitrite as nitrogen had migrated along a path following surface drainage features. In addition, the holding ponds on -site appeared to have impacted the quality of ground water at the site. At the time of the Phase II report submittal, neither the horizontal nor the vertical extent of nitrate/nitrite as nitrogen constituents had been adequately defined. After submission of the Phase II report, authorization to drill off -site to the east of the plant was granted. An off -site monitoring well was installed, sampled, and the ground water was analyzed for nitrates/nitrites as nitrogen. The results of the laboratory analysis of the ground water indicated a nitrate/nitrite as nitrogen level significantly below the NCDEHNR threshold value. Law's October 24, 1990, Addendum to the Phase II Groundwater Assessment details this work. PR\WA91-191\CAP [Jan. 31, 19941 CanonleEnviro=ental 4 On December 12, 1990, NCDEHNR issued a letter to Southern States requesting an additional (Phase III) site assessment. The letter requested that a deep monitoring well be installed and that a well survey of surrounding property be conducted. On April 16, 1991, Law issued a Phase III -A Assessment Report describing well installation and sampling activities conducted at the site. The NCDEHNR responded on May 14, 1991 with a letter stating that site assessment was approved. Three pilot test wells (RW-1, RW-2, and RW-3) were installed from September 30 through October 4, 1991 by Law. Test wells were extended into bedrock. The purpose of the test wells was to assess the extent of ground water impacts within fractured rock and to test the fractured rock hydrogeologic unit for the feasibility of recovering constituents. Test Well RW-2 contained the highest concentrations of nitrates/nitrites, and as a consequence was selected as the pumping well for an aquifer test. Packer tests and a step-drawdown test were performed on RW-2. Law issued a Summary of Installation and Evaluation of a Pilot Well System Report (Law, December 11, 1991) summarizing pilot test results. Closure of the two former holding ponds located approximately 1,000 feet southwest of the plant was completed in May 1992. A list of reports submitted to the NCDEHNR Mooresville Regional Office by Law is included in the references of this CAP. 1.3 Permits ,,On-l- ,-1.99-1-;'-the-NCOEH'Nl aassu:�d nc dNsch�a"rge Permi't`�Jo ° s 'lQO002 �5:56 to Southern States.

Law issued the Conceptual Design Report for Land Treatment of Pond Water and Sediments on September 25, 1990 for the purpose of obtaining this non -discharge permit. PRUA91-161\CAP [Jan. 31,19941 CanonieEnviro=ental 5 Spray irrigation was conducted at the site on a once -a -week basis during the period of July 11 through August 27, 1991. The water in both holding ponds was successfully removed, and the ponds were closed by removing the former dams and using soil from the dams to backfill low areas. A National Pollutant Discharge Elimination System (NPDES) permit was issued by the NCDEHNR on December 1, 1993 (Permit No. NC0082821) for the anticipated discharge of impacted ground water from the Southern States Site into Fourth Creek. The effective date of the permit is January 1, 1994. A copy of the NPDES Permit and application is included in Appendix B. 1.4 Hydrogeology The project site is located in the Piedmont Physiographic Province, an area underlain by ancient igneous and metamorphic rocks. The soils encountered in this area during previous assessment activities are the residual product of in -place weathering of rock which was similar to the rock presently underlying the site. In areas not altered by erosion or disturbed by human activities, the typical residual soil profile consists of silty and/or clayey soils near the surface, where soil weathering is more advanced, underlain by sandy silts and silty sands. The boundary between soil and rock is not sharply defined. This transitional "partially weathered rock" (PWR) zone, is normally found overlying the parent bedrock. PWR is defined, for engineering purposes, as residual material with standard penetration resistances in excess of 100 blows per foot. Weathering is facilitated by fractures, joints and by the presence of less resistant rock types. Consequently, the profile of the PWR and hard rock is quite irregular and erratic, even over short horizontal distances. In this geologic setting, the uppermost water table aquifer for ground water supply includes two components: soil and crystalline rock. Ground water in soil occurs under water table conditions. Water occupies the interstices between the grains of the residuum or saprolite (weathered rock) and is in hydrostatic balance with the atmosphere at the water surface (water table). Potentiometric contours for the water table aquifer usually mirror the topographic contours. In the underlying crystalline rocks, ground water occurs in fractures, joints and other openings in the rock. These PRMA91-16MAP [Jan. 31,19941 CanoweEnviro=ental 1.1 openings intersect the top of bedrock and are recharged by ground water from the storage in the overlying soil. In this geologic setting it is expected that large-scale fracture trends would not significantly control the direction of ground water movement on a local scale such as at the subject site. However, associated small-scale fractures parallel to the large- scale trends, if present, could result in a preferred direction of ground water movement in the rock beneath the site. Regional ground water flow is thought to be influenced by the general west to east surface water flow of Third and Fourth Creeks and the south and southeast flow directions of the unnamed creeks downgradient of the plant. Ground water elevation data was collected at site monitoring wells on February 18, 1991, and a potentiometric contour map for the soil/PWR hydrogeologic unit was prepared. Directions of ground water flow can be interpreted between wells by comparing the ground water elevation at those locations, and considering factors such as the topography, the lithology, the elevation of recharge and discharge areas, and manmade influences. Law's measurements revealed that the ground water flow direction is generally from northeast to southwest. Previous data confirm this ground water flow direction and further suggest that a ground water high point or "ridge" straddles the northeast corner of the site. Ground water northeast of the "ridge" flows northeast toward Fourth Creek, while ground water southwest of the ridge flows southwest and south toward Third Creek. Impacted ground water at the site is located southwest of the ridge and flows toward Third Creek. Ground water levels may fluctuate several feet with seasonal and rainfall variations. Normally, the highest ground water levels occur in late winter and spring, and the lowest levels occur in late summer and fall. Hydraulic gradients were determined by dividing the difference in ground water elevations at two locations by the horizontal distance between the two locations. Because of the extensive relief at the site, horizontal hydraulic gradients were determined between Monitoring Wells K65W6"A" and K65W7"A," and Monitoring PH\W:\91-161\CAP IJ4n. 31, 19941 CanonleEnviro=ental 7 Wells K65W7"A" and K65W7"G" (See Figure 2 for well locations). These monitoring wells are screened at approximately the same intervals, and they are oriented in the direction of preferential ground water, flow. Horizontal hydraulic gradients were calculated to be 0.032 feet per foot (ft/ft) and 0.031 ft/ft, respectively. Vertical hydraulic gradients were determined at Monitoring Well Clusters K65W6 and K65W7. At each location, the hydraulic gradient was determined between the shallow and deep wells. Vertical hydraulic gradients ranged from 0.021 ft/ft downward between Monitoring Wells K65W6"A" and K65W6"E" to 0.050 ft/ft downward between Monitoring Wells K65W7"A" and K65W7"I." The 0.050 ft/ft downward vertical hydraulic gradient is likely exaggerated due to the mounding effect of the water table near former Ponds No. 1 and 2. The vertical hydraulic gradient between Monitoring Wells K65W7"H" and K65W7"I" was approximately 0.027 ft/ft downward. In -flow permeability tests were performed in Monitoring Wells K65W6"B", K65W7"A" and K65W7"B" on March 25, 1991 to estimate the hydraulic conductivity of the soil at the site. In -flow permeabilities were calculated from the field data (Law, 1991). Hydraulic conductivities of the soil ranged from approximately 3 x 10-4 to 1 x 10-3 centimeters per second (cm/sec) based on in -flow permeability testing. Ground water flow velocity (v) is a function of hydraulic conductivity (k), hydraulic gradient (i) and the effective porosity (ne), as indicated in the equation: v = ki/ne. The effective porosity of the soil encountered at the screened intervals is estimated to be approximately 20 percent. Therefore, the lateral ground water flow velocity in the soil at the site can be expected to range from approximately 50 to 150 feet per year using an average horizontal gradient of 0.032 ft/ft. The rate of constituent migration may be different (generally slower) than that of the ground water, but is typically in the same general direction. PR1WA91-16MAP Wen.31.19841 CanonleEnvironmental 2.0 OBJECTIVE OF THE CAP The objective of this CAP is to describe the proposed ground water remediation system for the Southern States Fertilizer Plant located in Statesville, North Carolina. The primary objective of the remediation system is to protect the public health and the environment by controlling the off -site migration of ground water impacted with nitrates and nitrites at levels exceeding drinking water standards. Migration of impacted ground water will be hydraulically controlled by pumping impacted water from recovery wells. Ground water recovery wells will be located within high concentration areas and at the downgradient end of the plume of impacted ground water located on the Southern States property. Placement of a recovery well at the downgradient end of the plume will intercept impacted ground water and control off -site migration. Impacted ground water will be pumped from impacted areas and discharged to Fourth Creek, located north of the facility in accordance with conditions specified in the NPDES Permit. Impacted ground water will be removed until levels of nitrates and nitrites in monitoring wells at the facility meet the guidelines for drinking water quality according to 15A NCAC 2L (North Carolina Administrative Code). Table 1 contains sample results from initial monitoring at the site, as well as quarterly sampling begun in 1992 as requested by NCDEHNR. Ground water will be removed to achieve a level of 10 mg/I for nitrate as nitrogen and 1 mg/I for nitrite as nitrogen. The design goal for pumping and discharging impacted ground water is a rate of 100 gallons per minute (gpm). Since RW-2 (Figure 3) is the only recovery well currently installed, the actual pumping rate will be determined based on the yield capacity of two additional proposed recovery wells, RW-4 and RW-5. Discharge to Fourth Creek will be conducted in accordance with a National Pollutant Discharge Elimination System (NPDES) Permit (Permit No. NC0082821). The effective date of the permit is January 1, 1994. A copy of the NPDES Permit is included in Appendix B. Encroachment permits and letters of authorization for installation of discharge piping between the site and the point of discharge at Fourth PR%W:181-161\CAP [Jan. 31, 18941 CanonleEnvirol ' ental Creek have been secured from applicable parties. These parties include the State of North Carolina Department of Transportation (NCDOT), the Norfolk Southern Corporation, and private or commercial property owners along the route of the pipeline. PR\WAO1-161\CAP [Jan. 31, 19941 CanonfeEnvironmental 10 3.0 EXPOSURE ASSESSMENT Nitrate is a normal component of the human diet. A typical daily intake by an adult in the United States is about 75 mg/day (about 0.2 to 0.3 mg nitrate-nitrogen/kg/day) (NAS, 1981). Of this, over 85 percent comes from the. natural nitrate content of vegetables such as beets, celery, lettuce, and spinach. Daily intakes of nitrate by vegetarians may exceed 250 mg/day (0.8 mg/nitrate-nitrogen/kg/day) (NAS, 1981). The contribution from drinking water is usually quite small (about 2 to 3 percent of the total) (NAS, 1981), but could reach 85 mg/day (0.29 mg nitrate-nitrogen/kg/day) if water containing 10 mg nitrate-nitrogen/I was consumed. Thus, some adults consuming high levels of vegetables along with water containing high levels of nitrate (up to 10 mg nitrate-nitrogen/1) could receive total doses of nitrate approaching the Reference Dose of 1.6 mg nitrate-nitrogen/kg/day. Two health hazards are related to the consumption of water containing large concentrations of nitrate (or nitrite): induction of methemoglobinemia, particularly in infants, and possible formation of carcinogenic nitrosamines. Nitrate in water at concentrations less than a thousand milligrams per liter is not of serious concern as a direct toxicant. It is a health hazard because of its conversion to nitrite. Acute toxicity of nitrate occurs as a result of reduction to nitrite, a process that can occur under specific conditions in the stomach, as well as in the saliva. Nitrate toxicity is due primarily to its oxidation to nitrite, which oxidizes the Fe(+ 2) form of iron in hemoglobin to the Fe(+3) state. This compound (Methemoglobin) does not bind oxygen, resulting in overall reduced oxygen transport from lungs to tissues. Consequently, anoxia and death may ensue. Low levels of methemoglobin occur in normal individuals, with typical values usually ranging from 0.5 to 2.0 percent (NAS, 1981). However, due to the large excess capacity of blood to carry oxygen, levels of methemoglobin up to around 10 percent are not associated with any significant clinical signs (Walton, 1951; ECETOC, 1988). Concentrations above 10 percent may cause a bluish color to skin and lips (cyanosis), while values above 25 percent lead to weakness, rapid pulse, and tachypnea (Jones, et al., 1973). Death may occur if methemoglobin values exceed 50 to 60 percent. PR\W:181-181\CAP IJen.31, 1894► Can®nieEnvironmental r � Acute nitrate toxicity is almost always seen in infants rather than adults. This increased susceptibility of infants has been attributed to high intake per unit weight, to the high pH in the infant gastrointestinal system that favors the growth of nitrate - reducing bacteria, to the condition of the mucosa, and to greater ease of oxidation of fetal hemoglobin. ? No cases of methemoglobinemia have been proved conclusively to be caused by the consumption of water containing less than 10 mg of nitrate-nitrogen/I, and there are many examples where nitrate -nitrogen concentrations up to 20 mg/liter have not produced any clinical effects in infants. Although the clinical manifestations of infantile methemoglobinemia may not be apparent at these levels, undesirable increases in methemoglobin in the blood do occur. Epidemiological evidence on the occurrence of methemoglobinemia in infants tends to confirm a value near 10 mg/I nitrate as nitrogen as a maximum concentration level for water with no observed adverse health effects. For this reason, a guideline value of 10 mg of nitrate- ^ nitrogen/I is recommended. Infants (especially age 0 to 3 months) are generally recognized as being the subpopulation most susceptible to nitrate -induced methemoglobinemia. Risk is especially high in infants who are exposed to water that is contaminated with bacteria, since this tends to promote high concentrations of bacteria in the stomach and intestines. Nitrate is toxic when present in excessive amounts in drinking water, and in some cases, there is a possibility that certain forms of cancer might be associated with very high nitrate concentrations. Healthy adults are reported to be able to consume large quantities of nitrate in drinking water with relatively little, if any, effects. Conversion of nitrate to nitrite may also occur in the adult stomach if the pH of the gastric fluid is sufficiently high (above pH 5) to permit bacterial growth. This is of concern in adults with diseases such as achlorhydria or atrophic gastritis. It is also of concern in infants. Thus far, epidemiological studies have presented conflicting results on the relationship between drinking water nitrate levels and the incidence of gastric cancer in human PR\W:\91-161\CAP Wen. 31, 19941 CanonieEnviro=ental 12 adults. However, most studies conducted in Europe, China, and the United States suggest no significant increase in the incidence of gastric cancer in relationship to drinking water nitrate concentrations. Too many other factors, including diet and population mobility, modify the actual quantity of nitrate consumed. 3.1 Nitrite The widespread use of nitrates as fertilizers can lead to accumulation of this ion in food, plants, and water supplies, presenting a hazard to infants in whom intestinal bacteria cause reduction of nitrate to nitrite. While nitrite ion disappears rapidly from - the circulation, little is known of its fate (Rath and Krantz, 1942). Only one-third of a dose is excreted unchanged in the urine. Nitrite is directly toxic by reaction with hemoglobin to form methemoglobin and cause methemoglobinemia or "blue -baby syndrome" (cyanosis). It also reacts readily under appropriate conditions with secondary amines and similar nitrogenous compounds to form nitrogen-nitroso compounds, many of which are potential carcinogens. Hence the ingestion of nitrite leads to a more rapid onset of clinical effects, and for this ion, the guideline value is correspondingly lower than that for nitrate. Where drinking water is correctly treated, the nitrite/nitrogen level should be considerably lower than 1 mg/liter. 3.2 Exposure Pathways A well survey was conducted by Law in January 1991 (Law, April, 1991). No municipal drinking water wells are known to exist within a one -mile radius of the site. Residential wells are discussed in the following section. 3.2.1 Ground Water Usage Based on topography, regional ground water appears to flow toward the south and southeast. An unnamed creek which borders the site to the west and south appears to inhibit off -site migration of nitrate/nitrite, under static conditions. Possible off -site PR\WA91-191\CAP [Jan. 31, 19941 CanonleEnvironmental 13 migration eastward has been addressed and defined by former Monitoring Well K65W6"F" which indicated a nitrate level of 0.14 mg/I (as N). The nitrate/nitrite concentrations in deep wells at K65W6"E" and K65W7"1" indicate that the vertical extent of nitrate/nitrite can be substantially delineated. Several factors likely limit the migration of nitrate/nitrite from the site. Based on the well survey conducted by Law in January 1991, there appears to be few potential downgradient receptors of ground water nitrate/nitrite. Specifically, only three existing wells were located within 1,500 feet and topographically downgradient (southwest) of the Southern States Facility property line. These three wells have been sampled by the Iredell County Health Department. Several residential wells along Highway 70 were also sampled. Concentrations were significantly below the NCDEHNR nitrate/nitrite threshold values at these wells. Information concerning well construction, water pumping rates, and depth below ground surface of water withdrawal (screen interval) is not known for most of the surrounding off -site wells. The closest known wells are, locate' d east and northeast of the site on Highway 70. A group of approximately five homes is located a minimum of 1,600 feet west of the site, along Highway 70. Investigation of the United States Geological Survey (USGS) contour lines show the wells located along Highway 70 to be topographically upgradient of the suspected sources of ground water contamination. Furthermore, the two northernmost on -site wells (K65W4 and K65W5) indicated nitrate/nitrite concentrations below the recommended health guideline; 3.9 mg/I and 4.8 mg/I, respectively. Based on the topographic map of the area and site ground water elevation measurements obtained by the Department of Environmental Management in September 1989, the City of Statesville Fourth Creek Treatment Plant (north of Highway 70) appears to be isolated from Southern States by a ground water divide. The McNess and Jefferson Smurfit industrial sites located just east of Southern States obtain water from the Iredell Water Corporation. A City of Statesville water line runs along Highway 70 and extends east of the Southern States Facility where it connects to an Iredell Water Corporation water tower. PR\W:\81-1811CAP [Jan. 31, 19941 CanouteEnvironmental 14 The industrial sites along Moorehead Road are connected to the Iredell Water Corporation line. This line also connects to Wayside Estates and Forest Acres. The residential homes along Highway 70 are not connected to a municipal supply, but as previously stated are thought to be topographically upgradient. 3.2.2 Surface Water Usage An unnamed creek along the western boundary of the Southern States Facility is small with an estimated width of approximately 4 feet and a depth of approximately 6 inches. The creek receives flow from north of Highway 70. It flows south to southeast where it commingles with other small tributaries before entering Third Creek. The yield of this unnamed creek is so small and the access so difficult that surface water withdrawals from the creek are not likely. Section 15A NCAC 26.0309 of the North Carolina Administrative Code designates Third Creek as. Class C waters (secondary recreation and agriculture uses requiring water of lower quality): Table 3 illustrates nitrate concentrations measured during previous field sampling activities. 3.2.3 Soil Soil sampling results from previous investigations (Table 4) indicate very low concentrations of nitrates, which may be representative of background soil concentrations. The primary exposure route considered for this exposure assessment is consumption of drinking water, soil is not considered a possible exposure pathway. There are no published inhalation or direct contact values for nitrate. 3.3 Conclusions Nitrate has been classed a Category III contaminant with methemoglobinemia in infants identified as the most sensitive endpoint. A level of 10 mg of nitrate as nitrogen will protect infants, and all other groups against the non-oncogenic effects presented by nitrate in drinking water. In reaching this conclusion, the EPA examined a large body of studies concerning chronic toxicity, developmental and reproductive toxicity, and methemoglobinemia (among other endpoints). Both human and animal experimental data were included in this analysis. The Maximum Contaminant Level PR\WA91-16MAP Wan. 31, 19941 CanoftleEnvironmental 15 Goal (MCLG) is based upon a Drinking Water Exposure Limit (DWEL) for nitrate/nitrogen of 10 mg/I with an uncertainty factor of 1. Nitrite has been classed a Category III contaminant with methemoglobinemia in infants identified as the most sensitive endpoint. The MCLG of 1.0 mg/I for nitrite as nitrogen is based on a review of all available data that demonstrates that 1 mg/I is adequate to protect infants and all other groups against the non-oncogenic effects of nitrite in drinking water. The MCLG is based upon a DWEL for nitrite/nitrogen of 1 mg/I. PR\W:\91-181\CAP Win. 31, 18941 CanonleEnvironmental 16 4.0 EVALUATION OF REMEDIAL ALTERNATIVES This section discusses alternatives considered for remediation of ground water at the Southern States Facility. Remedial alternatives were evaluated in order to identify the most appropriate approach that would meet the objectives of the CAP. The technical and economic feasibility of a remedial option were considered during the evaluation of alternatives. Potential remedial alternatives for this site include: no action, institutional actions, ground water containment, ground water removal, ground water discharge, and ground water treatment. These alternatives are discussed below. Section 4.6 discusses the remedial alternative selected for the site. 4.1 No Action/Institutional Actions The no -action alternative would leave the site in its present condition without any remedial intervention. This alternative would not provide any additional protection to human health and the environment from adverse effects of ground water impacted by elevated levels of nitrate/nitrite as nitrogen.

Institutional actions include access restrictions, provision of alternate water supplies, and ground water monitoring. -Institutional actions, such as ground water monitoring, are seen as viable components of other remedial alternatives rather than alternatives themselves. Ground water sampling could be conducted to monitor changes in ground water movement, contaminant concentrations, and to evaluate the effectiveness of the selected remedial alternative. Other institutional actions such as provision of alternate water supplies and restricted access are not considered in this CAP as the approach to remediation is to reduce levels of nitrates and nitrites in the impacted plume as well as control the plume. PR\W-\81-161\CAP IJ&n.31.19941 CanonleEnvironmental M 4.2 Ground Water Containment The ground water containment alternative includes options such as slurry wall construction or sheet piling placement to isolate the impacted plume. The purpose of ground water containment is to prevent the lateral migration of chemicals in the ground water aquifer by creating a vertical barrier to flow. Implementation of any of the containment alternatives would have significant technical limitations due to the geology of the site. As detailed in the Law Environmental Ground Water Assessment Reports, the geology underlying the site consists of silty and/or clayey soils near the surface where soil weathering is more advanced, underlain by sandy silts and silty sands. The boundary between soil and rock is highly variable and not sharply defined. A transitional zone of partially weathered rock is normally found overlying parent bedrock. Ground water flow occurs in fractures, joints, and other openings in the bedrock. These openings intersect the top of bedrock and are recharged by ground water from storage in the overlying soil. It is expected that large-scale fractures at the site contribute to ground water flow. Also, associated small-scale fractures subparallel to the large-scale fractures could control the preferred direction of ground water flow at the site. A slurry wall or sheet piling constructed into this type of fractured bedrock would not create a barrier to flow due to the fracture network. The fracture system as well as the bedrock/soil interface are not defined well enough to adequately determine the depth and placement of the vertical barrier. Fracturing present in the underlying bedrock would potentially channel ground water beneath and circumvent the containment structure. In addition, construction of a slurry wall or sheet pile wall in fractured bedrock would be difficult due to the hardness of the rock. ;D_ue to this vanat ifity rn .the bedrock fracture._system and_'ihte�face; the ground -water co.ntainm'ent;alternative ha`s significanftechnical,-as�:w`ell-as=economic limitafion"s,_and" _" °therefote-is_ nof"�co:nsidered 4a_via�ble_r�medial6 �alterna"tive.-; PRMA91-16MAP [Jan. 31,1994] CanonleEnvironmental 18 4.3 Ground Water Removal Ground water removal involves the extraction of impacted ground water to achieve hydraulic control of an affected aquifer to prevent off -site migration. Ground water removal can also achieve reductions in levels of nitrates and nitrites through recharge of aquifers with un-impacted water. Removal technologies include ground water recovery wells and collection trenches. The effectiveness of ground water removal technologies are dependent on the hydraulic conditions of the site. Ground water assessments and pilot well system tests have been conducted at the Southern States Facility. As detailed in the Summary of Installation and Evaluation of a Pilot Well System Report (Law, 1991), various types of pumping tests (Packer tests, step drawdown tests, and aquifer tests) were conducted. Results of the tests indicate that Well RW-2 intersects fractures in the bedrock and is capable of producing a flow of 50 gpm or more. Hydraulic conductivities measured at various depths of the well range from 10-3 ft/min in the highly permeable upper zone (40 feet to 95 feet), 10-5 ft/min in a less permeable zone (95 feet to 109 feet), to 10-4 ft/min in a moderately permeable zone (109 feet to 166 feet). Well RW-2 is located at the downgradient end of the impacted plume identified on the Southern States Property. The availability of aquifers sufficient to produce significant flow rates, such as seen at RW-2, makes ground water removal using ground water pumping wells a viable and effective remedial option for the site. Location of a recovery well at the downgradient end of the impacted plume would function to control migration of the plume, as well. Strategic location of additional recovery wells will enhance this effect. Ground water collection trenches have technical and economic limitations as compared to recovery wells. The collection trenches would need to be very deep to achieve the flow rates required for this remedial alternative. The costs associated with installing a series of deep collection trenches would make this alternative prohibitively expensive. PR\WA91-191\CAP IJ�n. 31, 19941 CanonleEnviro=ental ii9l Discharge of ground water that could be removed by means of recovery wells is discussed below. 4.4 Ground Water Discharge Ground water discharge options were considered in accordance with the NCDEHNR Guidance for Evaluation of Wastewater Disposal Alternatives. Four discharge disposal alternatives were considered, as summarized below. A. Discharge to a Publicly Owned Treatment Works (POTW). B. Discharge to a Subsurface Disposal System. C. Discharge through a Spray Irrigation System. D. Discharge to a Flowing Stream. 4.4.1 Discharge to a POTW The Fourth Creek Water/Wastewater Treatment Plant is located approximately one mile northeast of the site (see Figure 1). This local POTW accepts municipal sewage from the city of Statesville. The Fourth Creek Water/Wastewater Treatment Plant agreed to consider acceptance of ground water discharge from the Southern States Facility. However, the treatment plant set forth the following requirements to be met prior to final acceptance: • An extra -territorial agreement to discharge must be executed; • A permit to discharge would be issued and include the city's option to discontinue acceptance upon due notice to the discharger; • The discharger would be billed at current (1992) outside sewer rates of $14.32 for the first 300 cubic feet and $4.70 per 100 cubic foot thereafter; • The discharger would have to bear all costs associated with tie-ins (taps, meters, etc.). PR\W:181-1811CAP [Jan. 31, 1B841 CanonleEnvironmental 20 Conversations with the POTW indicated that they do not possess any denitrification equipment at the treatment plant and would not attempt to reduce nitrate or nitrite concentrations from the Southern States discharge prior to eventual discharge into Fourth Creek. Also, pretreatment may be required to reduce the concentration of suspended solids from the discharge. The cost -of discharging the. impacted. ground water to the-POTW _would bay' high. The cost .associated-:with-tine'sewer_ rates loki =would _be__$0._62/100-gallon or 5331k,r28/year assurnmg a flow rate of_1.00 gpm. Additional costs for tie-in, meters, and pretreatment for suspended solids would also need to be considered. Discharge to the Fourth Creek Water/Wastewater Treatment Plant would be costly and would not significantly enhance the environmental quality of the water. This discharge system is not necessarily reliable, as the city maintains the option to discontinue acceptance of the water at any time upon due notice to the discharger. Accordingly, this option of discharge was dropped from further consideration. 4.4.2 Discharge to a Subsurface Disposal System The former holding ponds at the site appear to have been the source of nitrate/nitrate impact on ground water. The holding ponds have now been closed. The purpose of remediation at this site is to extract ground water and thereby.remove impacted water from the site, reducing nitrates/nitrites (as nitrogen) to concentrations acceptable to the NCDEHNR. To accomplish this goal, it will be necessary to remove ground water from the site. Reinjection of the water on -site would be counterproductive to this goal. Moreover, the water could not be reinjected on -site because on -site soils are fine grained and therefore low in permeability. Soil profiles in the area consist of silty and/or clayey soils near the surface. There is insufficient open land available (either on -site or on surrounding properties) to accommodate the anticipated 100 gpm flow rate. PRUA91-161TAP [Jan. 31, 19941 CanonleEnviro=ental 21 Discharge to a subsurface disposal system, or an infiltration gallery, has been determined to be technically and environmentally infeasible. This option was therefore dropped from further consideration. 4.4.3 Discharge Through a Spray Irrigation System On June 13, 1991, the NCDEHNR issued non -discharge Permit No. WQ0004556 to Southern States. The permit authorized spray irrigation of approximately 2.5 million gallons of water from two former holding ponds at the site. The permit was effective from the date of issuance through May 31, 1992. Spray irrigation was conducted at the site on a once -a -week basis during the period of July 11 through August 27, 1991. An area covering approximately 10 acres received the discharge, and grasses in the area were periodically harvested during the spray cycles to remove nitrogen from the site. The spray operation was limited to four hours per week to avoid runoff and/or erosion. The maximum allowable spray volume was 255,000 gallons per week, and the maximum allowable nitrogen loading rate was 250 pounds of nitrogen per acre per year. Concentrations of approximately 140 mg/I nitrate/nitrite (as nitrogen). are anticipated in the ground water discharge. Given the permit restrictions (runoff, nitrogen loading) outlined above, it has been determined that the previously permitted 10-acre spray irrigation system could accommodate flow of approximately five gpm. Approximately 200 to 300 acres of usable open land would be required to allow continuous spray irrigation. This land area is not available either on -site or on surrounding properties. Discharge through a spray irrigation system was determined to be technically infeasible, and this option was therefore dropped from further consideration. 4.4. 4 Discharge to a Flo wing Stream Discharge alternatives mentioned above were found to be either economically or technically infeasible. Discharge of ground water to a flowing stream was then evaluated. PR\W:\91.161\CAP [Jan. 31, 19941 CanoniieEnviro=ental 22 Fourth. Creek flows west to east about 1.5 miles north of the Southern States Site. The stream is classified Class C - aquatic life propagation and survival, fishing, wildlife, and secondary recreation. Based on 7Q10 flows calculated by the USGS (included in an attachment to the NPDES permit application contained in Appendix B), Fourth Creek meets the requirements for classification as a flowing stream. The minimum 7Q10 flow for Fourth Creek (7.3 cfs or 3,300 gpm) is sufficient to dilute the nitrate/nitrite (as nitrogen) concentrations to levels commensurate with Class C standards. Calculations based on the USGS flow rate (3,300 gpm) and the nitrate/nitrite concentrations previously identified in Fourth Creek (2.7 ppm) demonstrate that Fourth Creek can accommodate the proposed effluent without exceeding the Class-C:a:urfac ater standard of=17 mg/I for nitrates :and ,nitrite.s - cocnbined110 mg/I for nitrate and 1 mg/l for nitrite). Discharge to Fourth Creek is therefore seen as a viable and effective remedial approach to discharge of ground water removed from the impacted plume as described in the ground water removal option discussed above. Discharge to Fourth Creek would be economically feasible as well, essentially~having th_e_same __ _ environmental effect, as`discharge_to.the_POT N withdutaii"ditional fee, charges: A proposed point of discharge is shown on Figure 3. This discharge point was chosen because it is at the most easily accessible point on Fourth Creek relative to the Southern States Plant. 4.4.5 Summary of Ground Water Discharge Discharge to a flowing stream using an NPDES permit is the most environmentally sound and cost-effective alternative for this project. The other discharge options discussed above have been found to have significant economic, technical, or environmental limitations. PR\W:\81-181\CAP [Jan. 31, 19941 CanouteEnvironmental 23 4.5 Ground Water Treatment Ground water treatment options include technologies used to remove/reduce nitrates and nitrites (denitrification) from impacted ground water prior to discharge. Canonie conducted an evaluation of technologies for the denitrification of ground water (Canonie, 1992). These technologies included: ion exchange, reverse osmosis, and biological treatment. Based on a review of the treatment technologies, cb� iolo",-_aIj' �denrtrifieation, '&� proven and_ efi#ect vi e=treafinent method :is p efer�.ed :over the.:other j technologies: As stated in Section 4.4 above, ground water treatment is not necessary if ground water is discharged to Fourth Creek. Calculations based on a flow rate calculated by the USGS (3,300 gpm) and the nitrate/nitrite concentrations previously identified in Fourth Creek (2.7 ppm) demonstrate that Fourth Creek can accommodate the proposed effluent without exceeding the Class C surface water standards of 10 mg/I and 1 mg/I for nitrate and nitrite, respectively. 4.6 Recommended Alternative The recommended remedial alternative for this site includes three components discussed above: institutional controls (ground water monitoring), hydraulic control through ground water removal, and ground water discharge to a flowing stream (Fourth Creek). This alternative presents an effective and economical approach to remediation of ground water at the, Southern States Facility. Ground water monitoring will be implemented to assess the effectiveness of the remediation system. Ground water will be removed to both hydraulically control the movement of the impacted plume and to reduce levels of nitrates and nitrites in the plume. Discharge to Fourth Creek offers an economically and environmentally feasible approach to disposal of removed ground water. An estimate of the cost for implementation of the proposed remediation system is included in Table 2. PH\W:\91-181\CAP [Jan. 31, 19941 CanonieEnvironmental 24 5.0 PROPOSED CORRECTIVE ACTION PLAN A more detailed discussion of the proposed remediation system is provided below. 5.1 Description of System/Conceptual Design The proposed ground water remediation system for the CAP will reduce levels of nitrates and nitrites in the impacted aquifer to meet State of North Carolina drinking water guidelines. Nitrate levels as nitrogen in ground water will be reduced to 10 mg/I. Nitrite levels as nitrogen in ground water will be reduced to 1 mg/I. These reductions will be achieved by pumping ground water from the impacted aquifer and discharging this water directly into Fourth Creek, located north of the facility, as shown on Figure 3. Removal of ground water from the impacted aquifer will result in recharge of the aquifer with un-impacted water. Discharge of ground water to Fourth Creek will result in nitrate and nitrite levels within the creek below the regulatory limits. Recovery wells will be strategically located within high concentration areas and at the downgradient end of the plume of impacted ground water. Placement of one well at the downgradient end of the plume will function to intercept impacted ground water and control off -site migration. Three production wells will be installed for pumping and discharging impacted water. Wells RW-2, RW-4 and RW-5 are shown on Figure 3. Well RW-2 is an existing pilot test well that will be utilized as one of these recovery wells. Wells RW-4 and RW-5 will be installed as a `part of this CAP. Recovery wells have been located to maximize removal of ground water in high concentration areas as well as to minimize further migration of the impacted ground water plume. Well RW-2 is located at the farthest downgradient location of the plume on the Southern States Property. It will function to both remove impacted ground water and to intercept ground water migrating off -site. Wells RW-4 and RW-5 are located northeast of RW-2, along the center of the high concentration area (See Figure 4). RW-4 and RW-5 will remove impacted water from these areas of higher concentration. PR\WA91-16MAP [Jan. 31, 19941 Cano11ieEnvironmental 25 Pilot tests were conducted on three test wells at the site, including well RW-2. Pilot tests have indicated that ground water can be pumped at a rate of approximately 50 gpm at RW-2. Ground water pumping rates at proposed well locations, RW-4 and RW-5, have not yet been determined. As a consequence, the pumping capacity of the remediation system will not be known until construction of the system. It is the goal . of the ground water remediation system to pump and discharge ground water at a rate to achieve the objectives of this CAP. The estimated flow is 100 gpm with 50 gpm provided by RW-2 and the remaining 50 gpm provided by RW-4 and RW-5. Individual wells will discharge into a common pipeline. This pipeline will eventually discharge into Fourth Creek. A lift station will be provided to assist in the transport of piped water over the distances and gradients between the facility and Fourth Creek. 5.2 Selection of Remedial Approach As stated above, the proposed ground water remediation system for the Southern States Fertilizer Plant presents an effective and economical approach to the control of migration of ground water impacted with nitrates and nitrites. Selection of the remedial approach was based on its technical feasibility. Data provided by the previous site investigations were used in the assessment of the remedial approach. Based on the pilot test of RW-2, the radius of influence of this. well was approximately 900 feet to the north and 350 feet to the east and west. This radius of influence will act as a barrier to plume migration off -site to the south. A diagram of the radius of influence is included on Figure 4 and in the Summary of Installation and Evaluation of a Pilot Well System Report (Law, 1991). Aquifer test data from that report is included in Appendix F. Pumping tests on RW-2 indicate that it is capable of producing a sustainable flow rate of 50 gpm. The bulk of the ground water flow (approximately 70 percent) in the fractured rock at RW-2 will probably occur from the upper rock zone of the fractured rock unit (40 to 62 feet) due to the presence of a substantial fracture at the 50-foot depth. Approximately 90 percent of the ground water flow from RW-2 during the aquifer test PRUA91-16MAP [Jan. 31,19941 CanonleEnvironmental 26 emanated from above the 95-foot depth. Pumping from this interval will extract ground water which showed higher levels of nitrates/nitrites during Packer tests. Screen intervals for RW-4 and RW-5 were selected based on hydrogeological data and 4 water quality results. Lithologic cross sections in relation to water quality were reviewed for selection of screen depth intervals. Impacted ground water appears to be higher in the soil/PWR interface in the area of RW-5. From this point, ground water impacts appear to migrate downward and downgradient toward the PWR/bedrock interface in RW-4 and RW-2. Higher nitrate/nitrite concentrations seen in initial and quarterly ground water sample results (summarized in Table 1) in Monitoring Wells K65W6"A", K65W7"H", and K65W7"F" indicate this trend. Screens will be placed to extract ground water in these high nitrate/nitrite level intervals. Placement of screens for recovery wells will act to hydraulically control movement of impacted ground water as well as extract higher concentration ground water. Vertical cross sections of the proposed recovery wells are included on Figure 5. Engineering analyses were performed in the selection of a lift station to provide the necessary pressure to pump ground water over the distances and gradients to the discharge point at Fourth Creek. Engineering calculations and details on the lift station and discharge piping are included in Appendix C. 5.3 System Layout The locations of recovery wells for the ground water remediation system are shown on the base map on Figure 3. Ground water from Recovery Wells RW-2, RW-4 and RW-5 will pump into a 4-inch Standard Dimension Ratio (SDR) 11 high -density polyethylene (HDPE) pipeline which will discharge into a lift station. The lift station will provide the necessary pressure to pump ground water over the remaining distance to the discharge point at Fourth Creek. Discharge piping will follow the route as shown on Figure 3. Recovery Well RW-2 is an existing well that was utilized for a pilot test (Law, December 11, 1991). This well will be used as one of the recovery wells for the MWA81-181\CAP IJ&n. 31, 1884] Canofti-eEnvironmental 27 ground water remediation system. RW-2 is located downgradient in the nitrate/nitrite plume as shown on Figure 4. A 4-inch, 5 horsepower (hp) submersible well pump will be installed in the existing 6-inch well. Engineering calculations used for selection of well pumps are included in Appendix D. The well pump will be installed at a depth of 55 feet below ground surface. Prior to installation of the well, a 5-inch steel casing will be installed with a stainless steel screen set from 35 to 55 feet in depth. Screening of the well will prevent particulate matter from entering the well pump. 'i Intervals above and below the proposed well pump depth contained elevated concentrations of nitrates/nitrites. The well pump will be located in the bedrock interval approximately 20 feet below the PWR. Pumping from this interval will create a downward hydraulic gradient through the PWR unit and a lateral and upward hydraulic gradient through fractured rock. Location of the well at this depth will also take advantage of the significant water -bearing fracture in the bedrock at the 50-foot depth identified by Law during the pilot test. Ground water will be pumped from the open bedrock through the well screen. Prior to installation of the pump, Well RW-2 will be sealed off below the 110-foot depth either by the installation of a packer or grouting from the bottom of the well up to this depth. Grouting of this interval will isolate lower permeability and lower concentration intervals. A well construction detail for Recovery Well RW-2 is included in Appendix E. The design flow rate for Recovery Well RW-2 is approximately 50 gpm. Recovery Well RW-4 will be constructed as a part of this CAP. Recovery Well RW-4 will be drilled using air rotary drilling techniques. A 6-inch-diameter steel casing will be installed in this well. The well pump will be a 4-inch, 2 hp submersible pump. A 75-foot well screen will be placed to intersect soil, PWR, and bedrock. The appropriateness of the proposed screen slot size will be verified in the field during drilling. The top 10 feet of the screen will be installed in the soil horizon. The bottom 10 feet of the screen will be installed in bedrock, with the remaining screen portion in the PWR. Pumping from this interval will draw ground water from both the soil interval and the PWR/bedrock interface where elevated levels of nitrates/nitrites were detected. Pumping from the PWR/bedrock interface will create lateral and upward PMA91-16MAP [Jan. 31,19941 . Can®nleEnvironmental 1 28 ' hydraulic gradients resulting in the recovery of nitrate/nitrite-impacted ground water from the PWR and the underlying bedrock units. Pumping from the soil interval will draw impacted water detected in the water table formation. Based upon information from Well K65W7"H" located near proposed Recovery Well RW-4, the depth of the PWR/bedrock interface is approximately 100 feet. The actual location of the PWR/bedrock interval may differ, however, as this interval is highly variable throughout the site. As a consequence, the final construction of the well will be determined by field conditions. The goal for recovery of ground water at this well is 25 gpm. The actual flow rate of this well is contingent upon the hydraulic conductivity of the formations in this screen interval, which are unknown. The proposed well construction detail for Recovery Well RW-4 is included in Appendix E. Recovery Well RW-5 will be constructed as a part of this CAP, as well. Recovery Well RW-5 will be cased with a 6-inch-diameter steel casing. A 4-inch, 2 hp submersible well pump will be installed in this well. A 20-foot stainless -steel well screen will be installed at an approximate depth of 50 to 70 feet. This depth interval is based upon the depth to PWR of approximately 60 feet identified in Well K65W6"A", which is in the vicinity of RW-5. Screen installation at this interval is for the purpose of extracting ground water from both the soil and PWR formations. Elevated concentrations of nitrates/nitrites were seen at this interface in K65W6"A." The actual location of the soil/PWR interface may differ, however. The goal for recovery of ground water at this well is 25 gpm. The actual flow rate will be determined following construction of the well. The proposed well construction detail for RW-5 is included in Appendix E. A lift pump station will be located as shown on Figure 3. Ground water from RW-2, RW-4, and RW-5 will discharge into this station. This station is designed for a 100 gpm flow rate. The lift station will be a duplex pump type. Appendix C contains engineering calculations and construction details for this station. From the station, ground water will be pumped the remaining distance to the discharge point at Fourth Creek. The lift station will have two submersible pumps each sized for 59 feet of total dynamic head. The station will have a 15=minute holding capacity. A control panel will be mounted above the ground surface at this station. MWA91-16MAP [Jan. 31, 10941 CanonleEnvironmental 29 A control panel for the recovery wells, including hand -off -auto switches and motor starters, will be mounted adjacent to the lift station. The lift station control panel will ' be electrically interlocked with the recovery well control panel so that in the event of lift station failure or excessive water levels in the station tank, the well pumps will be shut off. The lift station will be provided with a visual and audible alarm. The lift station will be provided as a package unit for ease of operation and maintenance. A security fence and gate will be provided around the lift station and control panels. Discharge piping from the lift station will be 6-inch-diameter SDR 11 HDPE. Discharge piping will be installed a minimum of 3 feet below ground surface to insure protection from frost. A construction detail of the discharge piping trench is included on Figure 6. Clean -outs will be provided for every 1,000 feet of discharge piping for maintenance purposes. Discharge piping will cross a Norfolk Southern Railway Company main line and spur between the facility and the discharge point at Fourth Creek. Discharge piping will encroach in the right-of-way of U.S. Highway 70 and cross U.S. Highway 70 and State Road 2312. "Jack and Bore" installation techniques will be used to route the pipe under Hwy 70 and the Norfolk Southern Railroad. An 8-inch steel casing was originally proposed to contain 4-inch discharge piping for these crossings. A 10-inch steel casing will be necessary to contain the larger 6-inch HDPE piping proposed in this CAP. Appendix G includes the encroachment permits including the construction profile for these crossings. "Cut and Cover" trenching techniques will be used elsewhere along this line according to NCDOT's Right -of -Way Encroachment Checklist Guidelines. Ground water will be discharged into Fourth Creek at the point shown on Figure 3. It is anticipated that the initial level of nitrates/nitrites in the discharge stream will be approximately 140 mg/I. Levels of nitrates/nitrites in Fourth Creek (during 7Q10 low flow conditions) will rise from the existing level of 2.7 mg/I to a level of approximately 6.7 mg/I based on a weighted average of 3,300 gpm of minimum creek flow and 100 gpm of discharge flow. This level is below 11 mg/I, the combined regulatory levels for nitrates and nitrites for Class C surface waters. Erosion control will be provided to dissipate energy from the discharged water and transition water into the creek. A PR%W:181-161\CAP [Jan. 31, 19941 Canons-eEnvironmental 30 detail showing the outlet piping and erosion control measures at the discharge point is included on Figure 6. A process and instrumentation diagram for the ground water extraction and discharge system is shown on Figure 7. 5.4 Operation and Maintenance Pumping and discharge of impacted water to Fourth Creek offers an effective approach to remediation with minimal operation and maintenance. Limitations to this system are minimal. The system is designed to operate 24 hours a day, year-round. The proposed system will operate automatically. A full-time operator will not be required. Evaluation and maintenance of the system can be incorporated into the routine operation and maintenance activities of personnel at the Southern States Facility. Training of appropriate personnel can occur during system start-up. Well pumps will shut off in the event of high water levels in the lift station. A system failure will be indicated by a visual and audible alarm. The well pump control panel located at the lift station will indicate whether well pumps are operational. 5.5 Sampling Plan and System Evaluation Ground water sampling will be -conducted semi-annually to evaluate the ground water remediation system at the Southern States Plant. Semi-annual ground water sampling at the site was approved by NCDEHNR in its October 13, 1993 letter to Southern States. Sampling will be conducted in the same manner as the ground water sampling done previously at the plant. Monitoring wells K65W6"A"-"C", K65W7"A," K65W7"F", and K65W7"H" will be sampled two times each year. Prior to sampling, each well will be developed to bring fresh formation water into the well. A volume of water equal to at least three well volumes (or to dryness) will be removed from each well prior to sampling. Laboratory -cleaned stainless steel or disposable bailers and new polypropylene rope will be used to collect each sample. Ground water elevations will be taken from each well prior to sampling. Temperature, pH, and specific conductance will be measured during well development. Purge water generated during the sampling events will be discharged directly to the ground surface on -site. PR\W:\91-181\CAP [Jan. 31,19941 CanonleEnvironmental 31 Ground water samples will be placed in appropriate containers and shipped on ice overnight to an approved laboratory. Each sample will be analyzed for nitrite and nitrate using EPA Method 353.2. The ground water elevation measurements will be used to generate a ground water contour map semiannually to detect any changes in ground water movement. The nitrite and nitrate analytical results will be used to determine the plume geometry or the areal/vertical extent of contamination. The nitrite and nitrate results will also be used to evaluate the effectiveness of the ground water pumping system with regard to contaminant removal efficiencies and achievement of target cleanup concentrations. The ground water pumping system effluent will be sampled in accordance with the NPDES Permit to evaluate the effectiveness of the system and confirm that the NPDES discharge criteria are not violated. The NPDES Permit is discussed further in Section 6.0 and is included as Appendix B. PR\W:191-1811CAP [Jan. 31. , 994, CanonleEnvironmental 32 6.0 PERMITS The following permits have been obtained for the Southern States ground water remediation project: • NPDES Permit for ground water discharge to Fourth Creek; • NCDOT Right -of -Way Encroachment Permit; • Norfolk Southern Railroad Encroachment Permit. Also, written permission was obtained from eight property owners whose property will be used for placement of the discharge pipeline. The letters of authorization from the property owners are included with the NPDES permit application. Details on the permits are presented below. 6.1 NPDES Permit An NPDES Permit to discharge ground water, impacted with nitrates and nitrites into Fourth Creek has been obtained for the Southern States Fertilizer Plant. The permit application was submitted on September 10, 1992. The permit was granted and made final on December 1, 1993. A copy of the permit has been included as Appendix B. The permit is effective from January 1, 1994 to October 31, 1998. Effluent limitations are specified for ammonia (during April 1 to October 31 only) pH and total suspended solids. The permit also requires that the effluent (diluted to 3 percent) pass the North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure. Effluent monitoring requirements are specified as follows: PR1WA01-16MAP Wen. 31,19941 CanonleEnvironmental 33 Monitoring Requirements Effluent Characteristic Measurement Frequency Sample Type Sample Location Flow Continuous Recorded Effluent NH3 as N 2/Month Grab Effluent Total Suspended Residue 2/Month Grab Effluent Copper Monthly Grab Effluent Chlorides Monthly Grab Effluent NO3 - N Monthly Grab Effluent Chronic Toxicity (Ceriodaphnia) Quarterly Grab Effluent Total Nitrogen (NO2, NOZ, and TKN) Monthly Grab Effluent Total Phosphorous Monthly Grab Effluent pH Weekly Grab Effluent 6.2 NCDOT Right -of -Way Encroachment Permit A request for a Right -of -Way Encroachment Permit was submitted to the NCDOT on July 21, 1992. The NCDOT granted the permit on August 2.6, 1992. A copy of the permit is included as part of the NPDES permit application. The pipeline route will follow NCDOT right-of-way for approximately 6,100 feet as shown in Appendix G. The pipe will be installed on the south side of Highway 70 and will extend approximately 2,000 feet eastward from the Southern States Plant. The pipeline will then be routed northward under both Highway 70 and the Norfolk Southern Railroad. After crossing Highway 70, the line will run adjacent to the east side of SR 2313 for approximately 1,200 feet, cross SR 2312, and run approximately 2,900 feet northeastward. Finally, the line will be routed northward across private property to a discharge point at Fourth Creek. In areas where the pipeline parallels the roadway, it will be installed on NCDOT and/or Norfolk Southern rights -of -way.

DEM or Division Means the Division of Environmental Management, Department of Environment, Health and Natural Resources. 3. FMC Used herein means the North Carolina. Environmental Management Commission. 4. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq. 5. Mass/Day Measurements a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Monthly Average" in Part I of the permit. b. The "weekly average discharge" is defined as the total mass of all'daily discharges sampled and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the week and then dividing this sum by the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit. C. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitation is defined as "Annual Average" in Pait I of the permit. Part L B-9 Page 2 of 14 6. Concentration Measurement a. The "average monthly concentration," other,than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily. Maximum" under "Other Limits" in Part I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day . The average yearly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one dissolved oxygen -sample is taken over a calendar day, the sample is considered to be the "daily average concentration" for the discharge. It 'is identified as "daily average" in the text of Part L f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit. g. A calendar quarter is defined as one of the following distinct periods: January through March, April through June, July through September, and October through December. PartU B-10 Page 3 of 14 7. Other Measurements a. Flow, (MGD):, The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. 8. Types of Samples a. Composite Sample: A composite sample shall consist of: (1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the present gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six (6) hours nor the number of samples less than four (4) during a 24 hour sampling period. b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be representative of the discharge or the receiving waters. 9. Calculation of Means a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the'geometric mean, values -of zero (0) shall be'. considered to be one (1). W PartIl B-11 Page 4 of 14 c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. 10. Calendar Day A calendar day is defined as the period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. 11. Hazardous Substance A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. 12. Toxic Pollutant A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. SECTION B. GENERAL CONDITIONS 1.

SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS 1. Certified Operator Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the facility by the Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities., Such operator must hold a certification of the grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the Certification Commission. The permittee must also employ a certified back-up operator of the appropriate type and any grade to comply with the conditions of Title 15A, Chapter 8A .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of Title 15A, Chapter 8A .0202. Once the facility is classified, the permittee shall submit a letter to the Certification Commission which designates the operator in responsible charge within- thirty. days after the wastewater treatment facilities are 50% complete. )4 Part11 B-15 Page 8 of 14 2. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. 3. Need to Halt or Reduce not a Defense It. shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a. Definitions (1) "Bypass" means the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice (1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the'anticipated quality and affect of the bypass. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part 11, E. 6. of this permit. (24 hour notice). d. Prohibition of Bypass 0) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee for bypass, unless: ; (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal Part II B=16 Page 9 of 14 periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The permittee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph d. (1) of this section. 5. Una a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2) The permittee facility was at the time being properly operated; and (3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit. (4) The permittee complied with any remedial measures required under Part H, B. 2. of this permit d. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof. 6. Removed Substances - Solids, sludges, filter backwash, or other'pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as io prevent any pollutant from such materials from entering waters of the State or navigable:waters of the United States.

Z, y B-23 Part III Permit No. NC0082821 E. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in: 1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 3% (defined as treatment two in the North Carolina procedure document). The permit holder shall perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be performed after thirty days _ from. the effective date of this permit during the months of February, May, August and November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to quarterly in the months specified above. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit - suitable test results will constitute noncompliance with monitoring requirements. F. Because the receiving waters eventually enters High Rock Lake, which is eutrophic, minimum treatment of 15 mg/l total nitrogen and 2 mg/l total phosphorus is RECOMMENDED. More stringent controls on nutrient imputs may be required in the future. y3 B-24 PART N - ANNUAL ADMINISTERING AND COMPLIANCE MONITORING FEE REQUIREMENTS N A.

The facility was constructed in the 1950s. Southern States purchased the plant from W. R. Grace & Co. in February 1988. The manufacturing facility is currently self-contained; process water is recirculated within the plant without exterior discharge. This is possible because air scrubbers are used to reduce stack emissions. The scrubbers use a "wet" system, and the scrubber water is consumed in the granulation process. Prior to changes in scrubber design approximately 10 years ago, process water was discharged from time to time. Drainage was to the former ponds located approximately 1,000 feet southwest of the plant. Modifications to plant processes have been implemented over the past several years, and waste products appear to be appropriately contained within the manufacturing facility. A spill control review was conducted by Law Environmental in February 1990. The report concluded that the plant possessed adequate spill containment facilities, and the likelihood of a significant spill appeared to be low. On December 12, 1989, the NCDEHNR issued a Notice of Violation for the site. The notice stated that excessive concentrations of nitrate and/or nitrite (expressed as nitrogen) had been discovered in two NCDEHNR wells at the site. Combined nitrate/nitrite as nitrogen concentrations were greater than the threshold value of 11 mg/l set forth in Title 15, Subchapter 2L, Section .0202(g) of the North Carolina Administrative Code (15A NCAC 2L). The notice required submission of specific technical and field data documenting the ground water conditions. On January 19, 1990, representatives of Southern States and Law Environmental met with Messrs. Jesse Wells and Jeff Lautier at the NCDEHNR Mooresville office. All parties agreed that Law Environmental would construct six ground -water monitoring wells at the site. Two of the monitoring wells would be extended to bedrock (defined as auger refusal), and four would be shallow monitoring wells intended to address the lateral extent of nitrogen content. This initial well installation work was conducted during the period of January 30 through February 7, 1990. A response to the December 12, 1989 Notice'of Violation was presented in Law Environmental's "Phase I Ground -Water Assessment Report" dated March 29, 1990. Additional ground water assessment (Phase II) was recommended. AM NPDES Permit Application Attachment II: Site Background Information Page 2 The Phase II ground -water assessment activities were completed and a "Phase H Ground -Water Assessment Report" was submitted to NCDEHNR on September 25, 1990. Analytical results from Phase II analyses indicated that subsurface nitrate/nitrite concentrations had migrated along a path following surface drainage features. 'In addition, the holding ponds on -site appeared to have been the source of the impact on ground water at the site. At the time of the Phase II report submittal, neither the horizontal nor vertical extent of mtrate/nitrite impact had been defined. After submission of the Phase H report, permission to drill off -site to the east of the plant was obtained from the owner of the adjacent property. An off -site monitoring well was installed and sampled, and the ground water was analyzed for nitrate and nitrite concentrations. The results of the laboratory analysis of the ground water indicated a nitrate/nitrite level significantly below the NCDEHNR threshold value. These results were submitted to NCDEHNR on November 19, 1990. On December 12, 1990, NCDEHNR issued a letter to Southern States requesting additional (Phase III) site assessment. The letter requested that a deep monitoring well be installed and that a well survey of surrounding property be conducted. On April 16, 1991, Law Environmental issued a Phase III -A assessment report describing well installation and sampling activities conducted at the site. The NCDEHNR responded on May 14, 1991 with a letter stating that site. assessment was approved. The NCDEHNR letter required submission of a CAP within 60 days, as well as installation of one additional monitoring well south of the property. On June 26, 1991, representatives of Southern States met with Ms. Barbara Christian and Ms. Christine DeRoHer of NCDEHNR. At the meeting, NCDEHNR agreed to grant a 45-day extension of the submittal date. The NCDEHNR also agreed that the submittal should present a work plan outlining the steps necessary for the preparation and submittal of a CAP. On August 30, 1991, the CAP work plan was submitted to NCDEHNR. The work plan identified specific tasks necessary for the completion of the CAP, along with a schedule for completion. The tasks included completion of an aquifer pump test and development of a hydraulic control and ground -water treatment and/or disposal strategy. B-37 NPDES Permit Application Attachment II: Site Background Information Page 3 On October 9, 1991, NCDEHNR issued a letter to Southern States proposing a Special Order by Consent (SOC) which contained proposed terms. under which the CAP preparation and submittal were to proceed. These terms included the identification of specific tasks, along with due dates and associated penalties. On October 31, 1991, representatives of Southern States met with Ms. Barbara Christian and Ms. Christine DeRoRer of NCDEHNR to discuss the terms of the SOC. In the meeting, it was agreed that Southern States would initiate the NPDES permit application process prior to completion and submittal of the CAP, and no later than January 2, 1992. This approach was intended to facilitate assessment of the practicality of the CAP from an NPDES permit standpoint prior to the submittal of the CAP. This approach was also intended to minimize NPDES permit related delays in starting site remediation once the CAP is approved. Short Form C - Application for Permit to Discharge was submitted to the NCDEHNR by Law Environmental and Canome Environmental on December 31, 1991. On January 7, 1992, the NCDEHNR returned the application and requested that it be resubmitted using the recently developed Short Form C-GW and guidance documents for NPDES engineering proposal and engineering alternatives analyses. During the spring and summer of 1992, Law contacted property owners along the route of the proposed ground -water discharge line to Fourth Creek. All necessary authorizations have been obtained from property owners to allow placement of the discharge line. Also during this period, Law obtained encroachment permits for the proposed pipeline from the North Carolina Department of Transportation and the Norfolk Southern Railroad. Copies of these documents are included herein (Attachment V). The completed Short Form C-GW is included as Attachment I, as requested in the January 7, 1992 letter from the NCDEHNR. 1 ATTACHMENT III: CORRECTIVE ACTION PLAN an CORRECTIVE ACTION PLAN in support of APPLICATION FOR PERMIT TO DISCHARGE - SHORT FORM C-GW Southern States Fertilizer Plant Statesville, North Carolina LEI Job No. 56-1570.94 The corrective action plan, details of which are currently under development, is based on pumping impacted ground water from the site and discharging the extracted ground water into Fourth Creek. The location of the discharge point and the pipeline route are shown on the enclosed map (Drawing 1). Authorizations have been obtained from property owners along this route. Encroachment permits have also been issued by the North Carolina Department of Transportation and the Norfolk Southern Railroad (refer to Attachments IV and V). The total flow rate of extracted ground water from the site is not expected to exceed 100 gallons per minute. Initial nitrate/nitrite concentrations are expected to be approximately 140 mg/liter (as nitrogen): Concentrations are expected to decrease with time from the initial values. On December 26, 1991, water samples were collected from Fourth Creek near the proposed discharge point. The samples were sent to law Environmental National Laboratories and analyzed for nitrate and nitrite (as nitrogen). The concentration of nitrate (as nitrogen) in the sample from Fourth Creek was 2.7 mg/l. Nitrite was not detected above the 0.05 mg/l detection limits. The United States Geological Survey has calculated a 7Q10 flow rate for Fourth Creek at the State Road 2316 bridge of 7.3 cubic feet per second (approximately 3,300 gallons per minute). Based on this flow rate, and the low nitrate/nitrite (as nitrogen) concentrations identified by recent- sampling, it appears that the stream could accommodate the proposed effluent. A copy of the Fourth Creek surface water laboratory analyses results and USGS 7Q10 calculations are attached.

W ENGINEERING PROPOSAL in support of APPLICATION FOR PERMIT TO DISCHARGE - SHORT FORM C-GW Southern States Fertilizer Plant Statesville, North Carolina (' LEI Job No. 56-1570.94 The following information fulfills the seven requirements of regulation 15 NCAC 2H .0105 (c). 1. ORIGIN, TYPE AND FLOW OF WASTE TO BE DISCHARGED The proposed discharge effluent will be ground water pumped from an aquifer underlying the Southern States Fertilizer Plant. This ground water has been impacted with nitrates and nitrites (as nitrogen) at concentrations which exceed North Carolina dnnkmg water standards. The expected discharge flow rate will be 100 gallons per minute. Pumping is expected to last up to 10 years. The total yield will therefore be approximately 500 million gallons. 2. WASTE TREATMENT AND DISPOSAL OPTIONS Disposal options were considered in accordance with the, NCDEHNit Guidance for Evaluation of Wastewater Disposal Alternatives. Four discharge disposal alternatives were considered, as summarized below. A. Discharge to a Publicly Owned Treatment Works. B. Discharge to a Subsurface Disposal System. C. Discharge through a Spray Irrigation System. D. Discharge to a Flowing Stream. Information concerning each of these alternatives is presented on the following pages. B-51 NPDES Permit Application Attachment IV: Engineering Proposal Page 2 A. Discharge to a Publicly Owned Treatment Works. A publicly owned wastewater treatment plant is located approximately one mile northeast of the site. This facility (The Fourth Creek Water/Wastewater Treatment Plant, see Figure 1) accepts municipal sewage from the city of Statesville. On February 5, 1992, Law Environmental submitted a letter to the Director of the Fourth Creek Plant, Mr. Joe Hudson. The letter formally requested that the plant accept ground water discharged from the nearby Southern States site. Laboratory analyses of representative ground water samples were included in support of the request. A copy of the letter is attached. As outlined on the attached response from Mr. Hudson dated February 11, 1992, the Fourth Creek Water/Wastewater Treatment Plant agreed to consider acceptance of the proposed discharge. However, the treatment plant set forth several requirements which must be mdt prior to final acceptance. On February 26, Law responded to the plant with the following questions: 1. Does the Fourth Creek Treatment Plant have denitrification equipment? 2. Would the Fourth Creek plant treat the Southern States effluent to reduce the nitrate concentrations prior to discharge to Fourth Creek? ` 3. Would it be necessary for Southern States to pre -treat the ground water prior to I discharge? If so, what method(s) of pre-treatment would be required? A meeting between Law Environmental and Mr. Hudson was held on April 1, 1992. During the meeting, 1&. Hudson indicated that: 1. The plant does not possess denitrification equipment. l2. The plant would not attempt to reduce nitrate or nitrite concentrations prior to discharge into Fourth Creek. 3. Pretreatment might be necessary to reduce suspended solids. A summary of the meeting discussion (dated April 8) is attached. . ' In summary, the Fourth Creek Water/Wastewater Treatment Plant does not possess denitrification equipment. Therefore passage of water through the plant would not enhance environmental quality. Accordingly, this option of discharge was dropped from further consideration. I B-52 NPDES Permit Application Attachment IV: Engineering Proposal Page 3 S. Discharge to a Subsurface Disposal System. As outlined in the Background Information section of this document, former holding ponds at the site appear to have been the source of nitratetnitrite impact on ground water. The holding ponds have now been closed. The goal of remediation at this site will be to extract ground water and thereby remove impacted water from the site, reducing nitrates/nitrites (as nitrogen) to concentrations acceptable to the NCDEHNR. To accomplish this goal, it will be necessary to remove ground water from the site. Reinjection of the water on -site would be counterproductive to this goal. Moreover, the water could not be reinjected on -site because on -site soils are fine grained and therefore low in permeability. There is insufficient open land available (either on -site or on surrounding properties) to accommodate the anticipated 100 gallon per minute flow rates. I- Discharge to a subsurface disposal system, or infiltration gallery, was determined to be environmentally infeasible. This option was therefore dropped from further consideration. C. Discharge through a Spray Irrigation System. On June 13, 1991, the NCDEE NR issued non -discharge Permit No. WQ0004556 to Southern States Cooperative, Inc. The permit authorized spray irrigation of approximately 2.5 million gallons of water from two former holding ponds at the site. The permit was effective from the date of issuance through May 31, 1992. Spray irrigation was conducted at the site on a once -a -week basis during the period of July 11 through August 27, 1991. An area covering approximately 10 acres received the discharge, and grasses in the area were periodically harvested during the spray cycles to remove nitrogen from the site. The water in both holding ponds was successfully removed, and the ponds were closed by removing the former dams and using soil from the dams to backfill low areas. The spray operation was limited to four hours per week to avoid runoff. The maximum allowable spray volume was 255,000 gallons per week, and the maximum allowable nitrogen loading rate was 250 pounds of nitrogen per acre per year. r ; PAR Laboratories, Inc. 2217 GRAHAM PARK DRIVE LABORATORIES.

GW-30 Revised 5/ 15/89 i B-53 NPDES Permit Application Attachment IV: Engineering Proposal Page 4 As previously noted, concentrations of approximately 140 mg/1 nitrate/nitrite (as nitrogen) are anticipated in the ground -water discharge. Given the permit restrictions (runoff, nitrogen loading) outlined above, we have determined that the previously permitted 10-acre spray irrigation system could accommodate flow of only approximately five gallons per minute. Approximately 200 to 300 acres of usable open land would therefore be required to allow continuous spray irrigation. This land area is not available either on -site or on surrounding properties. Discharge through a spray irrigation system was found to be environmentally infeasible, and this option was therefore dropped from further consideration. D. Discharge to a Flowing Stream. Since the non -discharge alternatives mentioned above were found to be environmentally infeasible, discharging the Southern States ground water to a flowing stream was evaluated. Fourth Creek flows west -to -east about 1.5 miles north of the Southern States site. The stream is classified Class C - aquatic life propagation and survival, fishing, wildlife, and secondary recreation. Based on 7Q10 flows calculated by the United States Geological Survey, Fourth Creek meets the requirements for classification as a flowing stream. The 7Q10 flow for Fourth Creek is sufficient to dilute the nitrate/nitrite (as nitrogen) concentrations to levels commensurate with Class C standards. The proposed point of discharge is shown on the attached Figure 1. This discharge point was chosen because it is at the most easily accessible point on Fourth Creek relative to the Southern States plant. A four -inch diameter discharge line could be constructed from the plant eastward along Highway 70 to State Road 2313 (John Long Road). The pipe could then be routed northward, under Highway 70 and the Norfolk Southern Railroad tracks to State Road 2312 (Buckbee Road), and northeastward on Buckbee Road to private property adjoining Fourth Creek. Right -of -Way Encroachment Agreements for this route have been issued by the Department of Transportation and the Norfolk Southern Railroad (copies attached). In addition, the private property owner (Mr. James W. Davidson) has given written consent for the project. Please refer to Drawing 1 for a detailed route map. Copies of property owner consent forms for the proposed route are included in the Engineering Alternatives Analysis, Attachment V of this submittal. Summary of Waste Treatment and Disposal Options In our opinion, discharge to a flowing stream using an NPDES permit is the most environmentally sound alternative for this project. Non -discharge options have been found to be environmentally infeasible as outlined above. B-54 NPDES Permit Application Attachment IV: Engineering Proposal Page 5 3. DESCRIPTION OF PROPOSED TREATMENT WORKS The proposed effluent will not be treated prior to discharge into Fourth Creels. As previously noted, the 7Q10 flow of 3,300 gpm will be sufficient to fully assimilate a direct discharge of 100 gpm of ground water without treatment. 4. GENERAL LOCATION MAP A USGS topographic map showing the location of the Southern . States Facility, as well as the proposed discharge point at Fourth Creek, is attached as Figure 1. 5. SCALE PLAN OF SITE AND PROPOSED TREATMENT WORKS A scale plan of the site is attached as Figure 2. The plan shows the proposed ground -water recovery well locations. Effluent pipes will connect the wells and lead to Highway 70, then eastward to State Roads 2313 and 2312 and north across private property to Fourth Creek. The proposed point of discharge is shown on the attached Figure 1. The route is shown in detail on Drawing 1. 6. ENVIRONMENTAL IMPACT MODELING The Division of Environmental Management has not indicated that requirements of 15 NCAC 2H .0105 (c) (6) are necessary for the purposes of this application. 7.

"Joe" Hudson, Jr. Director Subject: Summary of Discussion April 1, 1992 Meeting Proposed Discharge from Southern States Fertilizer Plant to the Fourth Creek Wastewater Treatment Plant Statesville, North Carolina LEI Job No. 56-1570.94 Gentlemen: MMI-VI LAW ENVIRONMENTAL, INC. 4333 WILMONT ROAD, SUITE 300 CHARLOTTE, NORTH CAROLINA 28217 P.O. BOX 240674 CHARLOTTE, NORTH CAROLINA 28224-0674 704-357-1747 704-357-1622 (FAX) On April 1, 1992, Mr. Thomas Beggs of Law Environmental and Mr. Scott Smith of Canonie Environmental Services Corporation met with Mr. Hudson and Ms. Carol Rogers, Fourth Creek Wastewater Pretreatment Coordinator. The purpose of our meeting was to discuss several issues related to discharge of ground water from the Southern States Fertilizer Plant. This letter serves to summarize the discussion. PROJECT BACKGROUND Law and Canonie are continuing to evaluate the feasibility of discharging ground water from the Southern States property to the Fourth Creek plant. We anticipate that the site will yield a maximum of 100 gallons per minute, or approximately 50 million gallons per year. Initial nitrate/nitrite (as nitrogen) concentrations are expected to be 150 mg/l. Concentrations should decrease with time, and .the project is expected to continue for up to ten years. On February 5, 1992, Law submitted a formal request for authorization to discharge nitrogen - impacted water to the Fourth Creek plant. Detailed inorganic laboratory analyses of the proposed discharge were included with the request. (�7 Panted m Recvded PaDer B-61 n 1 u 7 L Fourth Creek Wastewater Treatment Plant April 8, 1992 page 2 The Fourth Creek plant responded to our request in a letter dated February 11. The letter set forth the following minimum requirements for discharge: 1. Extra -Territorial Agreement to discharge must be executed. 2. Permit to discharge would include the City's option to discontinue acceptance upon due notice to discharger. 3. Discharger would be billed at current outside sewer rates; $14.32 for the first 300 cubic feet and $4.70 per 100 cubic feet thereafter. 4. Discharger must bear all costs associated with tie-ins. On February 26, 1992, Law submitted a "request for additional information regarding treatment plant operations. The request was discussed in detail during our April 1 meeting. DISCUSSION OF PROPOSED DISCHARGE Mr. Hudson indicated that the Fourth Creek Wastewater Treatment Plant does not possess denitrification capability. However, minimal denitrification of nitrogen -impacted water may occur as a secondary benefit of aeration/clarification processes. The plant does not specifically attempt to remove nitrates or nitrites. If the Southern States effluent is accepted by the plant, denitrification would not be attempted by the plant prior to discharge of the water into Fourth Creek. The Fourth Creek plant is currently experiencing difficulty with solids in the waste stream. The policy of the plant is therefore to require pretreatment of effluent accepted from outside sources. The purpose of pretreatment is to minimize the suspended solids content. Carbon filtration or similar technology would be acceptable for this purpose. Mr. Beggs noted that the previously submitted inorganic laboratory analyses may not accurately represent production well effluent. The previous water samples were drawn from small -diameter monitoring wells. Production wells pumping continuously for extended periods should produce less turbid ground water. Production wells have not yet been installed at the site. Therefore, in an effort to simulate production conditions, the monitoring wells were resampled using a 45 micron nylon filter to screen suspended solids. The samples were again analyzed for the inorganic parameters, and the results have been summarized on the attached table. A copy of this table was provided to Ms. Rogers for review during the meeting. B-62 F Fourth Creek Wastewater Treatment Plant April 8, 1992 page 3 Mr. Hudson indicated that the Fourth Creek plant would adhere to the policy of pretreatment by carbon filtration and would reserve the right to inspect pretreatment facilities at any time. The plant would also require that an access valve be provided at the main treatment plant. The purpose of the valve would be to give plant personnel immediate flow control if unauthorized constituents are detected in the effluent. Trenching procedures for tie-in to the plant were briefly discussed during the meeting. Mr. Hudson indicated that the tie-in sewer line from Southern States should be routed around the Fourth Creek facility to the east. The plant has an extensive network of underground utilities, and installation ' of a sewer line through the plant could be disruptive. Mr. Hudson suggested that W. Wayne Lambert, Director of Public Works for the City of Statesville, be contacted prior to sewer line installation. The meeting was adjourned with the understanding that Law would issue a letter to document the discussions. We note that a final determination regarding discharge to the Fourth Creek plant may be delayed several months, pending review of our plans by the North Carolina Division of Environmental Management. If there are any questions regarding this letter, or if our understanding of the topics discussed is inaccurate, please contact us. attachment cc: Mr. Scott Smith Canonie Environmental Services Corporation Sincerely, LAW ENVIRONMENTAL, INC.

Boa 1111 Statesville, North Carolina 25677 Subject: Request for Additional Information Proposed Discharge from Southern States Fertilizer Plant to the Fourth Creek Wastewater Treatment Plant Statesville, North Carolina _ IE1 Job No. 56-1570.94 Dear Mr. Hudson: We have received your February 11, 1992 correspondence; thank -you for responding so quickly to our Request for Authorization to Discharge Nitrogen -Impacted Ground Water (letter dated February 5, 1992). Law Environmental is continuing to evaluate the feasibility of discharging ground water from the Southern States property to the Fourth Creek treatment plant. As you recall, we anticipate that the site will yield a maximum of 100 gallons per minute, or approximately 50 million. gallons per year. Initial nitrate/nitrite (as nitrogen) concentrations are expected to be 150 mg/l. Concentrations should decrease with time, and the project is aq=ted to continue for up to ten years. To assist in our efforts to evaluate the option of discharge to the Fourth Creek Treatment Plant, we would greatly appreciate your response to the following questions: 1 Does the Fourth Creek Treatment Plant have denitrification equipment? 2. Would the Fourth Creek plant treat the Southern States effluent to reduce the nitrate concentrations prior to discharge to Fourth Creek? 3. Would it be necessary for Southern States to pre -treat the ground water prior to discharge? If so, what method(s) of pre-treatment would be required? ,-�Printed on Recycled Pane( B-65 Mr. Joe Hudson February 26, 1992 Page 2 We appreciate your continuing assistance and look forward to hearing from you on these matters.

We are open to considering this favorably after further discussions with you. In order to assist you in further discussions the following are the minimum requirements at this time: 1. Extra -Territorial Agreement to discharge must be executed. 2. Permit to discharge will be issued and include the Citys option to discontinue acceptance upon due notice to discharger. 3. Discharger will be billed at current outside sewer rates which are at this time $14.32 for the first 300 cu.ft. and $4.70 per 100 cu. ft. after that. 4. Discharger will have to bear all costs associated with tie-ins (taps, meters, etc.) 1 B-67 If you would like to continue these discussions please call me at 704-878-3438.

Box 1111 Statesville, North Carolina 28677 Subject: Request for Authorization to Discharge Nitrogen -Impacted Ground Water Southern States Fertilizer Plant Hwy. 70 East, Statesville, North Carolina LEI Job No. 56-1570.94 Dear Mr. Hudson: As discussed during our January 21, 1992 meeting, Law Environmental is evaluating alternatives for disposal of nitrogen -impacted ground water from the Southern States Fertilizer Plant. The plant is located near your facility on Hwy. 70 East, Statesville, North Carolina. This letter serves as a request for authorization to discharge ground water recovered from the Southern States site to the Fourth Creek Water/Wastewater Treatment Plant. I The ground water removal project is being conducted in cooperation with the North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR). The NCDEHNR will establish guidelines for the removal of ground water which has been impacted by nitrates and nitrites. Southern States plans to begin ground -water extraction from three recovery wells during 1992. Based on the results of an aquifer pump test, we estimate that the site will yield a maximum of 100 gallons per minute (approximately 50 million gallons per year). Initial nitrate/nitrite (as nitrogen) concentrations are expected to be approximately 150 mg/l. 1 Concentrations are expected to decrease with time, and the project is anticipated to continue for up to -ten. years. 2570-PGG/qh '� Printed on Rewcled Paper .• Fourth Creek Treatment Plant February 5, 1992 Page 2 In addition to nitrates and nitrites, we have analyzed representative ground -water samples for a broad range. of inorganic parameters. Laboratory test results are attached for your review. We note that the samples were collected from monitoring wells at the site. In our opinion, the Total- Suspended Solids results are not representative of water which will be drawn from properly designed and fully developed recovery wells. In an effort to obtain representative ground -water samples to assist you in evaluating our request, our technicians will resample each monitoring well. The samples will be filtered in the field using Nalgene pressurized filters (45 micron nylon filter media) to remove suspended solids. Inorganic parameters will again be analyzed, and laboratory results will be forwarded to you as they become available. We hope that the information presented herein will allow you to determine whether ground water from Southern States can be discharged to -the Fourth Creek. Treatment Plant. If you have any questions or require additional information, please do not hesitate to contact us. Thank -you for your assistance on this project. Sincerely, LAW ENVIRONMENTAL, INC. P.

Basis of Presentation - The consolidated financial state- ments include the accounts of Southern States Cooperative, Inc. ("Southern States") and its wholly owned subsidiaries ithe "Company"). Upon consolidation, all significant intercompany accounts and transactions have been elimi- nated. Southern States' investment in Statesman Financial Corporation, a SO% -owned finance company, is accounted for by the equity method (see Note 6). b. Inventories and Cost of Products Sold - Inventories, except grain, are stated at the lower of cost or market. Cost is determined on various bases, including average, first -in, first - out, and specific- identification. Inventories of grain are stated at net market, as adjusted for unrealized gains and losses on hedged open purchase and sales contracts. Grain inventories are substantially hedged to minimize risks arising from market fluctuations. Patronage refunds from supplier cooperatives in the form of qualified written notices of allocation are recorded as received and are accounted for as reductions of cost of products purchased. Nonqualified writ- ten notices of allocation are not recorded until the cash is received. c. Property, Plant and Equipment - Property, plant and equipment is recorded at cost. The costs of property addi- tions, major renewals and betterments are capitalized while the costs of ordinary maintenance and repairs are charged to operations as incurred. The costs of property additions in- clude interest capitalized during major plant construction. Depreciation is determined principally by the straight-line method based on estimated useful lives (buildings and im- provements - 20 to 40 years; machinery and equipment - 4 to 20 vearsi. Gains and losses on disposition or retirement of assets are reflected in income as incurred. d. Investments - Investments, principally in supplier coop- eratives. are stated at cash invested plus unpaid qualified written notices of allocation. e. Income Taxes - For income tax purposes, Southern States is a nonexempt agricultural cooperative. accordingly, the Company does not pay income taxes on that portion of savings paid in qualified written notices of allocation arising from sales to members, patrons. eligible for membership and certain other patrons; such savings are included in the taxable income of these members and patrons. Deferred income taxes are provided on amounts resulting from timing differences between financial statement and income tax reporting of certain income and expenses Iprincipally depre- ciation, future employee benefits, environmental remediation costs, inventory costs and bad debts). f. Employee Retirement Plan - The employees of the Com- pany are covered under a multiemployer defined benefit plan. The Company's policy is to fund and expense an amount equal to the Company's share of the actuarially determined funding requirement of the plan. S. Common Stock and Patronage Refunds Payable - South- em States is an agricultural cooperative operating for the benefit of its stockholders/members and other patrons. Pur- suant to its bvlaws, Southern States is obligated to return all patronage sourced savings for each year, after payment of dividends on capital stock and reasonable additions to capital reserves, to such members, patrons eligible for membership and certain other patrons in proportion to the volume of business transacted with them during the year. See Note 11 with respect to requirements for membership and common stock ownership. h.Reclassifications - Certain reclassifications have been made to the 1990 financial statements to conform to the 1991 presentation. 2. Acquisition: Pursuant to an Agreement and Plan of Merger (the "Agree- ment") dated November 30,1989, a wholly owned subsidiary of Southern States (the "Subsidiary") acquired, in a purchase transaction, all of the outstanding common stock of The Wetsel Seed Company, Incorporated ("Wetsel") on January 2. 1990 in exchange for the following consideration: a. S1,813,900 in cash and $1,736,100 in the Subsidiary's Series 1 Class A cumulative redeemable 9% preferred stock (S 100 par value; see Note 11) ("9%, Redeemable Preferred"); b. S537,600 in cash and S512.600 in the Subsidiarv's 9'%n Redeemable Preferred, placed in escrow and subject to charges for certain expenses. fees and losses (e.g., losses arising from environmental matters) ("Losses"), with any.remaining bal- ance payable to Wetsel's stockholders on December 31,1991; and c. Up to $2,400,000 in cash and/or the Subsidiary's 9% Redeemable Preferred, if anv, if the Subsidiary achieves cer- tain financial results in the five fiscal years subsequent to July 1, 1989 ("Eamout Merger Consideration"). The Agreement stipulates that Losses in excess of the total funds available in escrow will reduce the Eamout Merger Consideration. The Agreement further provides remedies to the Company or its subsidiaries from Wetsel's stockholders for anv Losses in excess of anv of the Earnout Merger Consid- eration. The Subsidiary's 9% Redeemable Preferred is redeem- able at par value plus any accrued and unpaid dividends, at the option of either the Subsidiary or the holder, five years after its issuance. Effective with the acquisition, the name of the Subsidiary was changed to The Wetsel Seed Company, Inc. The Company's consolidated financial statements include the operating re- sults of the Subsidiary since January 2, 1990. 3. Managed Member Cooperatives: Under management agreements, Southern States performs various financial. accounting and management services for other agricultural cooperatives ("managed member coopera- tives"). There were 75 and.76 such.,cooperatives at June 30, 1991 and 1990, respectively: These managed member coop- eratives are owned entirely by their stockholders and patrons and thus are associated with Southern States solely by man- agement agreements (the "Agreements"). For services per- lim lyaelee formed, Southern States was reimbursed in the amount of S3,006,121 in 1991 and $3,079,787 in '1990. Under the Agreements, cash is advanced by Southern States (primarily as revolving advances for sales of products) and excess cash of the managed member cooperatives is advanced to Southern States. The interest rate charged or credited on monthly balances of these advances approximates the Na- tional Bank for Cooperatives' seasonal loan rate. Net interest income realized by Souther States on net advances totaled S288,416 and S309,164 in 1991 and 1990, respectively. Net purchases by patrons include purchases by managed member cooperatives of approximately $166,000,000 in 1991 and $152,000,000 in 1990. 4.

Southern States accounts for its 50% ownership in SFC by the equity method. SFC and Southern States are parties to an agreement under which SFC purchases, with recourse, a portion of Southern States' receivables. Under the terms of the agreement, South- ern States pays a fee of 1/8% of receivables sold (subject to a minimum of $5,000 per month) to SFC. In addition, the receivables are discounted at an amount sufficient to provide SFC with revenues equal to at least 100% of interest charges incurred on related indebtedness. Receivables sold to SFC totaled $564,014,000 and S503,779,000 for 1991 and 1990, respectively. The related fees and discounts for 1991 and 1990 were $3,237,000 and $3,044,000, respectively. SFC has entered into operating lease agreements with South- ern States whereby Southern States leases computer equip- ment, an airplane and liquid propane tanks from SFC.

(B)The Senior Notes, Series A (the "Notes") issued to Aetna Life Insurance Company and due August 4, 1999 are payable S1,000,000 annuallv 1992-1996, S2,000,000 in 1997 and S6,000,000 annually 1998-2000. The Company may prepay the Notes during the periods ending August 4, 1998 and .august 4, 1999 at 102% and 101%, respectively, of the outstanding principal. (C) Six industrial revenue financings require payments suffi- cient to enable the industrial development authorities to pay, as required, the principal, premium, if anv, and interest on the revenue bonds. The obligations mature serially in the following annual amounts - S1,038,333 in 1992, $1,073,333 in 1993, S1,098,333 in 1994, $1,633,333 in 1995, S1,213,333 in 1996 and in varying amounts ranging from S500,000 to S1,620,000 annually in 1997-2006. The obligations bear interest at rates ranging from 5.00% to 8.25%. Long -tern debt maturing within each of the four fiscal years after June 30, 1992 is as follows: 1993 - S10,042,515; 1994 - S23,167,727; 1995 - S10,595,921; and 1996 - S8,927,239. Under the most restrictive outstanding debt agreement, the Company is required to maintain, at fiscal year end, on a consolidated basis: (a) working capital of at least S65,000,000; (b) a ratio of current assets to current liabilities of at least 1.6 to 1; (c) net worth of at least 39% of total assets and not less than S 115,000,000; and (d) a ratio of adjusted long-term debt to net worth not to exceed .75 to 1. 11.Capital Stock: Southem States' authorized capital stock consists of 20,000,000 shares of common stock (S1 par value); 200,000 shares of cumulative preferred stock (S 100 par value), issuable in series, the redemption of which is limited to 20,000 shares annually; and 130,000 shares of NC Redeemable Preferred Stock ($100 par value). The Subsidiary has authorized 22,487 shares of 9% Redeemable Preferred ($100 par value) (see Note 2). The NC Preferred Stock is nonvoting (except as provided by statute), is junior to other existing preferred stock but prior to the common stock, and has fixed preferences as to dividends and liquidation: Such shares are subject to mandatory redemp- tion by Southern States-18,600 shares (S1,860,000) annually July 15, 1992 through July 15, 1995 and 18,400 shares (S1,840,000) on July 15, 1996 at par value plus any accrued and unpaid dividends. The 9% Redeemable Preferred is re- deemable at par value plus any accrued and unpaid dividends, at the option of either the Subsidiary or the holder, five years after its issuance. Southern States' authorized common stock is membership common stock and, pursuant to the requirements of the Agricultural Cooperative Association Act of Virginia and the Company's Articles of Incorporation and bylaws, its issuance or transfer is limited to bona fide producers of agricultural products and cooperative associations that are owned and controlled by such producers who use the services or supplies of Southern States. Dividends on Southern States' common stock are limited annually to 6% of its aggregate par value. Each member, regardless of the number of shares of common stock registered in the member's name, is entitled to one vote in the affairs of the Company. Under various circumstances the Company repurchases common stock from its members at par value plus declared and unpaid dividends, if any. In the event of liquidation or other disposition of the Company's assets, the holders of common stock, after satisfaction of obligations to holden of all preferred stock, would be entitled to receive a maximum of S 1 per share (par value) plus declared and unpaid dividends, if any. m Changes in preferred stock ($100 par) and common stock 61 par) during 1990 and 1991 were as follows: 7 1/2% 9% 5%-6% Preferred Redeemable NC Preferred Redeemable Preferred Common Aggregate Aggregate aggregate Aggregate Shares Par Value Shares Par Value Shares Par Value Shares Par Value Balances, June 30, 1989 20,204 $2,020,400 130,000 S13,000,000 11.202,627 S11,202,627 Issued 272 27,200 1 22,487 S2.248.700 5,007 5,007 Redeemed (1,166) (116,600) (18,600) (1,860,000) (674,893) (674.893) Balances, June 30, 1990 19,310 1,931,000 111,400 11,140,000 22.487 52.248,700 10.532,741 10.532,741 Issued 281 28,100 9,834 9,834 Redeemed (1,049) (104,900) (18,600) (1,860.000) (143,835) (143.835) Balances, June 30, 1991 18,542 S1,854.200 92.800 - $9,280,000 22.487 S2.248.700 10.398.740 S10,398,740 12. Employee Benefit and Compensation Plans: Southern States sponsors a multiemplover defined benefit retirement plan (the "Plan") which is noncontributory and includes substantially all employees of Southern States and 75 managed member cooperatives. For 1991 and 1990, Southern States' expenses, including administrative expenses, were S2,705,756 and S2,497,380, respectively. A comparison -of accumulated benefits and net assets of the Plan, as estimated by the Plan's actuary, is presented below. The information relating specifically to Southern States' employees is not available. Actuarial present value of plan benefits: Vested Nonvested Total benefits Net assets available for benefits July 1 1990 1989 S 63,722,232 S60,903,825 2,462,446 1,971,306 S 66,184,678 S62.875,131 S80,193,688 S75,636,510 Under Southern States' 401(k) plan, Southern States matches employee contributions and may make discretionary contri- butions. Employee contributions are matched to the extent of 40% of the participant's first 3% contributed and 15% of the next 2% contributed. Southern States' matching contribu- tions for 1991 and 1990 were $474,883 and $334,125, respec- tively. Effective January 1,1991, the Subsidiary profit sharing plan was merged into the Southern States' 401(k) plan (See Note 2). Southern States provides certain medical and life insurance benefits for retired employees. Substantially all of Southern States' employees may become eligible for those benefits, generally upon attaining normal retirement age while em- ploved by Southern States. Those and similar benefits for active employees are provided through an insurance com- pany whose premiums are based on benefits paid. Southern States recognizes the cost of providing these benefits by expensing the annual insurance premiums. For 1991, the premiums for retired employees were S22,266 for life insur- ance and S827,303 for medical insurance. For 1990, such premiums were S19,815 and $335,020, respectively. In December 1990, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No.106, "Employers' Accounting for Postretirement Benefits Other Than Pensions" ("SFAS 106"). The new standard requires companies to accrue the cost of such benefits, primarily health care and life insurance, during the employee's period of service rather than the current practice of recognizing costs as claims are paid. The standard must be adopted during the Company's 1994 fiscal year. The Company has not com- pleted the complex analyses required to, determine the full impact of SFAS 106; however, the Company believes that even though adoption will most likely result in higher em- ployee benefit expense, adoption will not impact cash flow and will not have a material adverse effect on the Company's financial position. Southern States has in effect other compensation plans for key management and retail branch personnel under which current and deferred awards, based principally on operating results, are made. The aggregate charge to operations with respect to these plans"approxirtiated'S1,095,000 in 1991 and $1,121,000 in 1990. SOUTHERN C"rot,mv ;• N� 13.

When adopted, SFAS 96 will change the method of calculating the provision for income taxes, but will have no impact on actual tax payments. Based on statutory income tax rates currently in effect, management does not expect that the adoption of SFAS 96 will have a significant impact on the Company's financial position or future net income. 14. Texas City Refining Investment: On June 30,1988, Texas City Refining, Inc. ("TCR") (33-1/3% owned by Southern States) sold its refinery segment, which represented a substantial portion of TCR's operations, to Phibro Refining - Texas City, Inc. ("Phibro"), an affiliate of Hill Petroleum Company, for S33,000,000. The sale agree- ment provided for contingent compensation to TCR of up to $5,000,000 based upon future prices of crude oil and up to S15,000,000 based upon future profits of the refinery sold to Phibro. As of June 30, 1991 crude oil prices did not meet the prescribed levels for contingent compensation, therefore relieving Phibro of the obligation to make the S5,000,000 contingent payment to TCR. The remaining $15,000,000 of contingent compensation will be payable to TCR after June 30,1993 if the conditions of the sale agreement are met. The Company has a $1 million receivable from TCR which it expects to recover from TCR's disposition of its remaining assets (See Note 4). IS. Commitments and Other Matters: a. Leases - Southern States is a partyto an agreement whereby an investment company (the "Owner") constructed, on land owned by Southern States and leased to the Owner for a 70- year term expiring in 2048, a headquarters building for lease to Southern States. Under the terms of the building lease, Southern States is obligated to pay rent I net of income from the land rental) based upon the cost of the building and executory costs such as insurance, maintenance and property taxes. This operating lease has an initial term of 30 years, expiring in October 2008, and contains options allowing Southern States to renew the lease for two additional five-year periods and to purchase the building, at certain times through- out the lease, at the greater of the building's original cost or its then fair market value as defined in the lease. Should Southern States not exercise its purchase option by the expiration of the building lease, the Owner has options, exercisable throughout the remaining term of the land lease, to purchase the land at its then fair market value. In addition, the Company leases transportation, data process- ing and other equipment under operating leases expiring generally during the next five years. Rental expense approxi- mated 56,594,000 in 1991 and S6,565,000 in 1990. The Company's approximate minimum lease commitments under noncancellable operating leases, less noncancellable subleases, are as follows: Office Building Year Equipment Lease Subleases Totals 1992 S3,439,000 5 736,000 S(600,000) S 3,575;000 1993 2.315,000 736.000 (157,000) 2,894,000 1994 2,100,000 740,000 2,840.000 1995 1,175,000 742,000 1,917,000 1996 678,000 742,000 1,420,000 Thereafter 253,000 9.096.000 9,349,000 b. Other Matters -The Company's 1991 and 1990 consoli- dated statement of operations -includes a provision in cost of products purchased and marketed and other operating costs of $2,008,700 and S3,122,707, respectively, to cover esti- mated environmental remediation costs. The unpaid por- tion of such costs totaled S2,298,903 and $2,140,680 at June 30, 1991 and 1990, respectively, and is included as a liability in the Company's consolidated balance sheet for the respec- tive years. The remaining actual environmental remediation liability•may be different from management's estimates due to: the uncertainty of the extent of pollution, the complexity of laws and government regulations and their interpretation, the varying costs and effectiveness of alternative cleanup technologies and methods, the uncertain level of insurance or other types of recovery, and the questionable level of the Company's involvement. The Company is a defendant in several lawsuits arising in the ordinary course of business. While the outcome of any litigation cannot -be predicted with certainty, the Company. believes that the ultimate disposition of these matters will not have a materially adverse effect on its consolidated financial position or business. At June 30, 1991, commitments for the construction and acquisition of plant and equipment totaled approximately S7,280,000. 38 16. Supplemental Disclosures of Cash Flow Information: The components of cash provided by (used in) current assets and liabilities, net of effects of acquisitions of Wetsel, follow: 1991 1990 Receivables $ 8,352,984 $ (1,897,031) Inventories (5,585,877) 6,120,694 Refundable income taxes 457,199 391,773 Prepaid expenses (656,004) (413,062) Accounts payable 1,697,095 (7,101,779) Accrued expenses (1,060,133) 4,514,604 Other (net) (1,120,021) (666,173) S 2,085,243 $ 949,026 To the Board of Directors Southern States Cooperative, Inc. Cash payments for interest (net of amounts capitalized) were S12,238,025 and S12,010,410 for 1991 and 1990, respec- tively. Cash payments for income taxes were $2,791,294 and $3,078,067 for 1991 and 1990, respectively. Southern States' acquisition of Wetsel included the following cash and noncash transactions: Fair value of net assets acquired, including acquisition costs of $277,059 Cash acquired 9% Redeemable Preferred issued to sellers Cash. paid We have audited the consolidated balance sheet of Southern States Cooperative, Inc. and subsidiaries (the "Company") as of June 30, 1991 and 1990, and the related consolidated statements of operations, patrons' equity, and cash flows for the years then ended. These financial statements are the responsibility. of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Southern States Cooperative, Inc. and subsidiaries as of June 30, 1991 and 1990, and the consolidated results of their operations and their cash flows for the years then ended in conformity with generally accepted accounting principles.

Evaluation of Envirorunental Feasibility Disposal options were considered in accordance with the NCDEHNR Guidance for Evaluation of Wastewater Disposal Alternatives. Four discharge disposal alternatives were considered, as summarized below. 1. Discharge to a Publicly Owned -Treatment Works. 2. Discharge to a Subsurface Disposal System. 3. Discharge through a Spray Irrigation System. 4. Discharge to a Flowing Stream. Information concerning each of these alternatives is presented on the following pages. 1. Discharge to a Publicly Owned Treatment Works. a. Existing Sewerage System A publicly owned wastewater treatment plant is located approximately one mile northeast of the site. This facility (The Fourth Creek Water/Wastewater Treatment Plant, see Figure 1) accepts municipal sewage from the city of Statesville. On February 5, 1992, Law Environmental submitted a letter to the Director of the Fourth Creek Plant, Mr. Joe Hudson. The letter formally requested that the plant accept ground water discharged from the nearby Southern States site. Laboratory analyses of representative ground water samples were included in support of the request. A copy of the letter is attached. As outlined on the attached response from Mr. Hudson dated February 11, 1992, the Fourth Creek Water/Wastewater Treatment Plant agreed to consider acceptance of the proposed discharge. However, the treatment° plant set forth several requirements which must be met prior to final acceptance. B-94 NPDES Permit Application Attachment V: Engineering Alternatives Analysis Page 3 On February 26, Law responded to the plant with the following questions: 1. Does the Fourth Creek Treatment Plant have denitrification equipment? 2. Would the Fourth Creek plant treat the Southern States effluent to reduce the nitrate concentrations prior to discharge to Fourth Creek? 3. Would it be necessary for Southern States to pre -treat the ground water prior to discharge? If so, what method(s) of pre-treatment would be required? A meeting between Law Environmental and Mr. Hudson was held on April 1, 1992. During the` meeting, Mr. Hudson indicated that: 1. The plant does not possess denitrification equipment. 2. The plant would not attempt to reduce nitrate or nitrite concentrations prior to discharge into Fourth Creek. 3. Pretreatment might be necessary to reduce suspended solids. A summary of the meeting discussion (dated April 8) is attached. In summary, the Fourth Creek Water/Wastewater Treatment Plant does not possess denitrification equipment. Therefore passage of water through the plant would not enhance environmental quality. Accordingly, this option of discharge was dropped from further consideration. b. Planned Sewerage System The City of Statesville municipal government operates two wastewater treatment plants; one is on Third Creek approximately three miles west and upgradient of the Southern States site, and one is on Fourth Creek approximately one mile northeast of the site. The nearer facility (on Fourth Creek) was constructed in 1981 and was recently expanded. The Assistant Director for both plants is Mr. Steven Lambert. On February 6, 1992, we discussed with Mr. Lambert future City plans for wastewater treatment. Mr. Lambert indicated that the recent expansions of Fourth Creek plant were designed to provide sufficient capacity for many years. Therefore, no new wastewater treatment plants are planned for construction within the next five years. Furthermore, no expansion of treatment plant technology is planned to provide denitrification capabilities. 2. Discharge to a Subsurface Disposal System. As outlined in the Background Information section of this document (Attachment I% former holding ponds at the site appear to have been the source of mtrate/nitrite impact on ground water. The holding ponds have now been closed. The goal of remediation at this site will be to extract ground water and thereby remove impacted water from the site, reducing nitrates/nitrites (as nitrogen) to concentrations acceptable to the NCDEHNIL NPDES Permit Application Attachment V: Engineering Alternatives Analysis Page 4 To accomplish this goal, it will be necessary to remove ground water from the site. Reinjection of the water on -site would be counterproductive to this goal. Moreover, the water could not be reinjected on -site because on -site soils are fine grained and therefore low in permeability. There is insufficient open land available (either on -site or on surrounding properties) to accommodate the anticipated 100 gallon per minute flow rates. Discharge to a subsurface disposal system, or infiltration gallery, was determined to be environmentally infeasible. This option was therefore dropped from further consideration. 3. Discharge through a Spray Irrigation System. On June 13, 1991, the NCDEHNR issued non -discharge Permit No. WQ0004556 to Southern States Cooperative, Inc. The permit authorized spray irrigation of approximately 2.5 million gallons of water from two former holding ponds at the site. The permit was effective from the date of issuance through May 31, 1992. Spray irrigation was conducted at the site on a once -a -week basis during the period of July 11 through August 27, 1991. An area covering approximately 10 acres received the discharge, and grasses in the area were periodically harvested during the spray cycles to remove nitrogen from the site. The water in both holding ponds was successfully removed, and the ponds were closed by removing the former dams and using soil from the dams to backfill low areas. The spray operation was limited to four hours per week to avoid runoff. The maximum allowable spray volume was 255,000 gallons per week, and the maximum allowable nitrogen loading rate was 250 pounds of nitrogen per acre per year. As previously noted, concentrations of approximately 140 mg/1 nitrate/nitrite (as nitrogen) are anticipated in the ground -water discharge. Given the permit restrictions (runoff, nitrogen loading) outlined above, we, have determined that the previously permitted 10-acre spray irrigation system could accommodate flow of only approximately five gallons per minute. Approximately 200 to 300 acres of usable open land would therefore be required to allow continuous spray irrigation. This land area is not available either on -site or on surrounding properties. Discharge through a spray irrigation system was found to be environmentally infeasible, and this option was therefore dropped from further consideration. MI. NPDES Permit Application Attachment V: Engineering Alternatives Analysis Page 5 B. Review of EnvirrvnmentaaFeanbMy Each of the three discharge alternatives outlined above have been found to be environmentally infeasible. Therefore, we have considered the option of discharging recovered ground water to Fourth Creek under an NPDES permit. The environmental feasibility of this option is outlined below. C. Discharge to a Flowing Sbearn The nearest flowing stream is Fourth Creek. Fourth Creek flows west -to -east about 1.5 miles north of the Southern States site. - The stream is classified Class C - aquatic life propagation and survival, fishing, wildlife, and secondary recreation. Based on 7Q10 flows calculated by the United States Geological Survey, Fourth Creek meets the requirements for classification as a flowing stream. The 7Q10 flow for Fourth Creek is sufficient to dilute the nitrate/nitrite (as nitrogen) concentrations to levels commensurate with Class C standards. The proposed point of discharge is shown on the attached Figure 1. This discharge point was chosen because it is at the most easily accessible point on Fourth Creek relative to the Southern States plant. A four -inch diameter discharge line could be constructed from the plant eastward along Highway 70 to State Road 2313 (John Long Road). The pipe could then be routed northward, under Highway 70 and the Norfolk Southern Railroad tracks to State Road 2312 (Buckbee Road), and northeastward on Buckbee Road to private property adjoining Fourth Creek. Right -of -Way Encroachment Agreements for this route have been issued by the Department of Transportation and the Norfolk Southern Railroad (copies attached). In addition, the private property owner (Mr. James W. Davidson) has given written consent for the project. Please refer to Drawing 1 for a detailed route map. Copies of property owner consent forms for the proposed route are attached. 111. COST ESTIMATION AND COMPARISON Only one of the four discharge alternatives was found to be environmentally feasible.

"Joe" Hudson, Jr. Director Subject: Summary of Discussion April 1, 1992 Meeting Proposed Discharge from Southern States Fertilizer Plant to the Fourth Creek Wastewater Treatment Plant Statesville, North Carolina LEI Job No. 56-1570.94 Gentlemen: On April 1, 1992, Mr. Thomas Beggs of Law Environmental and Mr. Scott Smith of Canonie Environmental Services Corporation met with Mr. Hudson and Ms. Carol Rogers, Fourth Creek Wastewater Pretreatment Coordinator. The purpose of our meeting was to discuss several issues related to discharge of ground water from the Southern States Fertilizer Plant. This letter serves to summarize the discussion. - PROJECT BACKGROUND Law and Canonie are continuing to evaluate the feasibility of discharging ground water from the Southern States property to the Fourth Creek plant. We anticipate that the site will yield a maximum of 100 gallons per minute, or approximately 50 million gallons per year. Initial nitrate/nitrite (as nitrogen) concentrations are expected to be 150 mg/l. Concentrations should decrease with time, and the project is expected to continue for up to ten years. On February 5, 1992, Law submitted a formal request for authorization to discharge' nitrogen - impacted water to the Fourth Creek plant. Detailed inorganic laboratory analyses of the proposed discharge were included with the request. B-103 Fourth Creek Wastewater Treatment Plant April 8, 1992 page 2 The Fourth Creek plant responded to our request in a letter dated February 11. The letter set forth the following minimum requirements for discharge: 1. Extra -Territorial Agreement to discharge must be executed. 2. Permit to discharge would include the City's option to discontinue acceptance upon due notice to discharger. 3. Discharger would be billed at current outside sewer rates; $14.32 for the first 300 cubic feet and $4.70 per 100 cubic feet thereafter. 4. Discharger must bear all costs associated with tie-ins.. - On February 26, 1992, Law submitted a request for additional information regarding treatment plant operations. The request was discussed in detail during our April 1 meeting. DISCUSSION OF PROPOSED DISCHARGE Mr. Hudson indicated that the Fourth Creek Wastewater Treatment Plant does not possess denitrification capability. However, minimal denitrification of nitrogen -impacted water may occur as a secondary benefit of aeration/clarification processes. The plant does not specifically attempt to remove nitrates or nitrites. If the Southern States effluent is accepted by the plant, denitrification would not be attempted by the plant prior to discharge of the water into Fourth Creek. The Fourth Creek plant is currently experiencing difficulty with solids in the waste stream. The policy of the plant is therefore to require pretreatment of effluent accepted from outside sources. The purpose of pretreatment is to minimize the suspended solids content. Carbon filtration or similar technology would be acceptable for this purpose. Mr. Beggs noted that the previously submitted inorganic laboratory analyses may not accurately represent production well effluent. The previous water samples were drawn from small -diameter monitoring wells. Production wells pumping continuously for extended periods should produce less turbid ground water. Production wells have not yet been installed at the site. Therefore, in an effort to simulate production conditions, the monitoring wells were resampled using a 45 micron nylon filter to screen suspended solids. The samples were again analyzed for the inorganic parameters, and the results have been summarized on the attached table. A copy of this table was provided to Ms. Rogers for review during the meeting. B-101 2. Correspondence with Fourth Creek Publicly Owned Treatment Works B-104 Fourth Creek Wastewater Treatment Plant April 8, 1992 page 3 Mr. Hudson indicated that the Fourth Creek plant would adhere to the policy of pretreatment by carbon filtration and would reserve the right to inspect pretreatment facilities at any time. The plant would also require that an access valve be provided at the main treatment plant. The purpose of the valve would be to give plant personnel immediate flow control if unauthorized constituents are detected in the effluent. Trenching procedures for tie -into the plant were briefly discussed during the meeting. Mr. Hudson indicated that the tie-in sewer line from Southern States should be routed around the Fourth Creek facility to the east. The plant has an extensive network of underground utilities, and installation of a sewer line through the plant could be disruptive. Mr. Hudson suggested that Mr. Wayne Lambert, Director of Public Works for the City of Statesville, be contacted prior to sewer line installation. The meeting was adjourned with the understanding that Law would issue a letter to document the discussions. We note that a final determination regarding discharge to the Fourth Creek plant may be delayed several months, pending review of our plans by the North Carolina Division of Environmental Management. If there are any questions regarding this letter, or if our understanding of the topics discussed is inaccurate, please contact us. Sincerely, LAW ENVIRONMENTAL, INC. Thomas F. Beggs, P.E.

Law Environmental is continuing to evaluate the feasibility of discharging ground water from the Southern States property to the Fourth Creek treatment plant. As you recall, we anticipate that the site will yield a maximum of 100 gallons per minute, or approximately 50 million gallons per year® Initial nitrate/nitrite (as nitrogen) concentrations are expected to be 150 mg/l. Concentrations should decrease with time, and the project is expected to continue for up to ten years - To assist in our efforts to evaluate the option of discharge to the Fourth Creek Treatment Plant, we would greatly appreciate your response to the following questions: 1. Does the Fourth Creek Treatment Plant have denitrification equipment? 2. Would the Fourth Creek plant treat the Southern States effluent to reduce the nitrate concentrations prior to discharge to Fourth Creek? 3. Would it be necessary for Southern States to pre -treat the ground water prior to discharge? If so, what method(s) of pre-treatment would be required? 12, B-107 Mr. Joe Hudson February 26, 1992 Page 2 We appreciate your continuing assistance and look forward to hearing from you on these matters.

Box 1111 Statesville, North Carolina 25677 Subject: Request for Authorization to Discharge Nitrogen -Impacted Ground Water Southern States Fertilizer Plant Hwy. 70 East, Statesville, North Carolina LEI Job No. 56-1570.94 Dear Mr. Hudson: As discussed during our January 21, 1992 meeting, Law Environmental is evaluating alternatives for disposal of nitrogen -impacted ground water from the Southern States Fertilizer Plant. The plant is located near your facility on Hwy. 70 East, Statesville, North Carolina. This letter serves as a request for authorization to discharge ground water recovered from the Southern States site to the Fourth Creek Water/Wastewater Treatment Plant. The ground water removal project is being conducted in cooperation with the North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR). The NCDEHNR will establish guidelines for the removal of ground water which has been impacted by nitrates and nitrites. Southern States plans to begin ground -water extraction from three recovery wells during 1992. Based on the results of an aquifer pump test, we estimate that the site will yield a maximum of 100 gallons per minute (approximately 50 million gallons per year). Initial nitrate/nitrite (as nitrogen) concentrations are expected to be approximately 150 mg/l. Concentrations are expected to decrease with time, and the -project is anticipated to continue for up to ten years. 1570-PGG/qb B-111 1 Fourth Creek Treatment Plant February 5, 1992 Page 2 In addition to nitrates and nitrites, we have analyzed representative ground -;water samples for a broad range of inorganic parameters. Laboratory test results are attached for your review. We note that the samples were collected from monitoring wells at the site. In our opinion, the Total Suspended Solids results are not representative of water which will be drawn from properly designed and fully developed recovery wells. In an effort to obtain representative ground -water samples to assist you in evaluating our request, our technicians will resample each monitoring well. The samples will be filtered in the field using Nalgene pressurized filters (45 micron nylon filter media) to remove suspended solids. Inorganic parameters will again be analyzed, and laboratory results will be forwarded to you as they become available. We hope that the information presented herein will allow you to determine whether ground water from Southern States can be discharged to the Fourth Creek Treatment Plant. If you have any questions or require additional information, please do not hesitate to contact us. Thank -you for your assistance on this project.

The line will run along Highway 70 from the Southern States Fertilizer Plant eastward to John Long Road. The line will then be drilled under Highway 70 and the Norfolk Southern Railroad, following John Long Road northward to Fourth Creek. The proposed route is shown on the attached drawing. The line will be installed on North Carolina Department of Transportation right-of-way. However, the NCDOT has suggested that we get approval for the work from property owners along the proposed route. The pipeline will be carefully placed in an excavated trench that is six -inches wide and thirty -inches deep. After the pipe is located in the trench, the excavation will be carefully backfilled with compacted soil. Any damage'to your yard or pavement caused by this work will be repaired by Southern States at its expense. we will do our best to leave your yard in the same condition as it was before the excavation. Our field crew will not obstruct traffic to your property, and the water line will not interfere with your existing utilities.

Pipe Size Selection _ Since 6,800 feet, 4-inch pipe from Point A to Point G produces 136 feet friction resistance and gravity flow from Point G to Point I, 1,700 feet needs 6-inch pipe, it is concluded to use 6-inch pipe all the way from Lift Station A to Fourth Creek _ Point J. Total length from Point A to Point J - 9,800 feet Elbow, valves, etc. loss equivalent pipe length = 200 feet (see Page C-7) Friction loss = 0.13 psi/100 feet Total friction loss = 0.13 psi x 9.800 + 200 = 13 psi 100 = 30 feet of water This 6-inch pipe will run from Point A to Point J and transfer manhole at Point G is not needed. The 4-inch pipe has a friction loss too high and to run 10,000-foot pipe on one single line is not technically appropriate. ti The advantages in using 6-inch HDPE pipes for the whole line are: • Use only one third of the horsepower for the pumps when comparing 4-inch HDPE pipe line with 200-foot head and 6-inch pipe with 60-foot head. ' • Pump life is longer. • Less chance of high-pressure water hammer develops. • Fittings subject to smaller forces. • Pumps require single stage impeller and the initial cost is lower. There is no need for multiple stages. • Larger electrical supply line is not needed. • Less maintenance cost.

Two shut-off valves - will be installed on the 6-inch HDPE pipe near each end of the casing. See Sketch No. 7 for jacking pipe profile. Thermal Expansion and Contraction of HDPE Pipe In most buried pipeline installations, a significant degree of restraint is automatically provided due to soil friction. This is further controlled because the pipe usually lies in a slight "S" curve in the trench as it is installed. Because the temperature of the soil is fairly constant, temperature changes that do occur take place over a yearly season. Because of the enormous heat sink capability of the -earth, the magnitude of any temperature change is reduced and the time required to effect that temperature change is extended. Usually the summer and winter soil temperature difference is about 30°F. This 30OF temperature change occurs over seven months at a rate of _- nearly 0.143°F per day. In addition to soil friction overcoming a thermally imposed stress, the pipeline has an entire season to stress relax and dissipate that stress. If a minor temperature change does occur, its effect is further minimized by the water thermal inertia within the pipe. Therefore, the thermal effect on the pipe is negligible.

TYPICAL 4" DIAL INDICATOR -TOTALIZER DESCRIPTION MODEL ML-04 FLANGED TUBE METERS are manufactured to the highest standards. Materials used on all meters and flow ranges for the low velocity motor meet or exceed AWWA standard C704. The flanged end tube design permits use in a wide range of applications with up to 150 psi worldng pressure. Flanged ends are 150 lb. AWWA class D flat face steel flanges. Fabricated steel meter tubes have straighteningvanes and are protected internally and externally with 12-15 mils of fusion epoxy resin. INSTALLATION is made'similarto placing ashort length of flanged end Pipe in the line. The meter can be installed horizontally, or inclined on suction or discharge lines. However the indicator -totalizer must be positioned in the upward direction on the top of the 0peonly. The meter m ust have a full flow of liquid for proper accuracy. Valves, fittings, or other obstru ctions that tend to set upflow disturbances should beaminimum offive pipe diameters upstream and one Pipe diameterdownstream from the meter. PROPELLER is magnetically coupled with the drive mechanism through the sealed oil filled gearbox. This completely eliminates water entering the meterassembly, as well as the need for any packing gland. The propeller is a conical shaped three bladed propeller, injection molded of thermoplastic material resistant to normal water corrosion and deformity due to high flow velocities. BEARING in propeller is a water lubricated ceramic sleeve bearing that rides on a ceramic coated stainless steel spindle. Dual ceramic thrust bearings, standard on all meters, handle flows in both forward and reverse directions. The bearing design promotes extended periods of maintenance free propeller operation. Bearings within the sealed meter mechanism are shielded precision stainless steel bearings and are facory lubricated for the life of the meter. INDICATOR TOTALIZER ismechanically driven by the metermechanismand features a full 4' diameter, 250 degree sweep dial with a six digit, straight reading type totalizer and sweep test hand. The indicator drive mechanism is temperature compensated so the indicator will be accurate at all points on the dial when operated between 32° and 140- F. The indicator dial can be furnished in GPM, CFS, MGD or any standard liquid measuring units with choice of standard totalizer measuring units. The bonnet, with padlock hasp, is o-ring sealed to the meter head. CHANGE GEARS may be easily exchanged in the field when changing the dial, or when recalibrating fordifferent pipesizes. It is not necessary to remove pressure from the line for these changes. O-RING SEALS are used at the meter head and all points where seals are required, making the meter mechanism completely immune to any of the corrosive effects of atmospheric moisture or the liquids measured by the meter assembly.

The reliability of the printed circuit cards and solid state components utilized in construction provide continued accurate and dependable operation of the instrument OPERATION. Electronic circuitry within the transmitter furnishes a4.20made current signal proportional to the rate of flow through the measuring unit The current input signal drives the recorder mechanism. Internal power supply is furnished to provide power to transmitter. INSTALLATION of the case can be made through the front of an instrument panel or to any flat surface. Two mounting brackets hold the unitsec urey in place in either installation. For the best operation of the system the signal line should be of an armored cable and the powerand signal lines to the instrument should be placed in separate conduits to prevent extraneous voltages from interfering with the signal. CASE is impact resistant thermoplastic with a pressure latched, gasketed door with viewing window that seals the instrument from dust and moisture. INDICATOR is digital LED, and may be configured to read in gallons per minute, cubic feet per second, or any liquid rate measuring units. TOTALIZER is digital LED, and may beconfigured to read in gallons, cubicfeet, orany liquid measuring units. CHART DRIVE may be configured so chart rotation is equal to 24 hours, 7 days, 31 days, oroptionalspeeds from 6hours to31 days. Chartrotationisspscifiedwhen ordering and set at the factory. CHART is standard 12" and is heat sensitive, so it is supplied "blank". Unit prints its own chart including all dates, times, flow data, etc, as selected by the user.
