OF ENVIRONMENT AND NATURAL RESOURCES RECEIVED DEC 2 9 2004 MOORESVILLE REGIONAL OFFICE DWO-GROUNDWATER SECTION On behalf of Southern States Cooperative, Inc. (Southern States), MACTEC Engineering and Consulting, Inc., formerly Law Engineering and Environmental Services, Inc. (MACTEC) has completed the first and second semi-annual ground -water sampling events for 2003 at the subject site (Figure 1). The work was performed according to MACTEC's Meeting Notes — March 5, 2003 Site Visit, dated March 20, 2003. This report briefly outlines our recently completed field activities and the results of the ground -water analyses. Background The previous schedule of sampling and reporting consisted of semi-annual sampling and analysis from selected site monitoring wells for nitrite and nitrate. The semi-annual sampling was performed during April and October of each year. Ground water was recovered from recovery wells RW-2 and RW-4 five months of the year (November, through March), followed by no pumping for seven months (April through October). Cyclical pumping allows ground water to recover in all of the monitoring wells during the time when the recovery wells are not operating, thus enabling them all to be sampled. The monitoring wells are sampled and analyzed for nitrite and nitrate. Recovery wells are also sampled for nitrite and nitrate but only during the time when they operate. As a result of the Report Review and Site Reranking correspondence dated September 17, 2002, the North Carolina Department of Environment and Natural Resources (NCDENR) requested the spring 2003 semi-annual sampling event be conducted approximately one month after the recovery MACTEC Engineering and Consulting, Inc. 2801 Yorkmond Rd., Suite 100 • Charlotte, NC 28208 704-357-8600 • Fax: 704-357-8638 2004 Annual Report December 22, 2004 Southern States Fertilizer Plant MACTEC Project No. 6228-04-1072 system was shut down to allow the ground -water table to return to non -pumping elevations. Additionally, NCDENR requested the analysis of ammonia in addition to nitrate and nitrite for the spring 2003 sampling event. On March 5, 2003, a site meeting was held at the facility between representatives of Southern States, MACTEC, and Mr. Matt Heller of NCDENR. At this time we discussed the current operation of the recovery system and sampling and reporting schedule. Mr. Heller requested continuation of semi-annual sampling from the site monitoring wells in April and October of each year and annual reporting by November 30 of each year. Recovery and Monitoring Well Abandonment and Replacement The realignment of US 70 through the site necessitated that North Carolina Department of Transportation (NCDOT) acquire a right-of-way through the property (see Figure 2). This right- of-way will encompass an area within which three of our monitoring wells and one of the recovery wells (i.e., RW-4; see Figure 2) were located at the site. Therefore, MACTEC abandoned the three monitoring wells K65W7 "A", K65W7 "H" and K65W7 "I" and recovery well RW-4 and replaced them in August 2004. The three new wells K65W7 "J", K65W7 "K", K65W7 "L" and the recovery well RW-6 were installed to the northeast of the abandoned wells. The new wells were surveyed to a relative elevation. Additionally, a top of casing (TOC) measurement for the well was recorded relative to well K65W6 "D". Well construction details/construction records and well completion logs are provided in Appendix'A. Well locations are shown on Figure 2. Field Sampling On April 16, 2004, and October 28, 2004, MACTEC collected representative samples of ground water from on -site monitoring wells (Figure 2). Depths to ground water were measured at each monitoring well prior to well purging and are summarized in Table 1. Ground -water flow for the site is illustrated on the ground -water contour maps for each sampling event (Figures 3 and 4). The contours represent equipotential lines for the respective set of data. The natural direction of ground- water flow is toward the south-southwest. Field sampling procedures followed those normally employed to gather ground -water samples from monitoring wells and were outlined in the approved Corrective Action Plan (CAP) of January 28, 1994 for ground -water recovery. Each well was first purged to bring fresh formation water into the well. A volume of water equal to at least three well volumes (or to dryness twice) was 2 2004 Annual Report December 22, 2004 Southern States Fertilizer Plant MACTEC Project No. 6228-04-I072 removed from each well prior to sampling. Disposable bailers and new polypropylene rope were used to collect each sample. Field indicator parameters of pH, temperature, and specific conductivity were measured with calibrated meters after purging each well volume of ground water. The semi-annual ground -water monitoring program consists of sampling the following wells: K65W6 "A" K65W6 "E" K65W7 "D" K65W7 "H" K65W7 "L" K65W6 `B" K65W7 "A" K65W7 "E" K65W7 "I" RW-2 K65W6 "C" K65W7 `B" K65W7 "F" K65W7 "J" RW-4 K65W6 "D" K65W7 "C" K65W7 "G" K65W7 "K" RW-5 During the April 16, 2004 sampling event, Wells K65W6 "D", K65W7 "C", K65W7 "E", and K65W7 "G" did not have sufficient water to purge or sample. During the October 28, 2004 sampling event, Wells K65W6 "D" and K65W7 "C" did not have sufficient water to purge or sample. During the October 28, 2004 sampling event, Wells K65W7 `B" and K65W7 "B" could not be located. Monitoring well K65W6 "C" was covered with fill material due to previous construction activities at the site, and as a result was inaccessible for future reporting periods. Therefore, this well could not be purged or sampled during the reporting period. Ground -water samples were placed in laboratory provided containers and delivered on ice to Pace Analytical Laboratories, Inc. in Huntersville, North Carolina. Ground -water temperature, specific conductance, and pH were measured at the time of sampling and are provided in Table 2. Analytical Results On April 16, 2004 the indicator parameters (pH, temperature and specific conductivity) were measured at each well, prior to sample collection. The results of the field parameters are summarized in Table 2. Specific conductance of the ground -water samples ranged from 81.4 µmhos/cm (K65W7 "D") to 2,930 µmhos/cm (K65W6 "A"). Values of pH ranged from 4.0 (K65W7 "A") to 7.63 (K65W6 "E"). The temperature of the ground -water samples ranged from 12.7 °C (K65W7 "D") to 18.0 °C (K65W6"B"). 3 2004 Annual Report December 22, 2004 Southern States Fertilizer Plant MACTEC Project No. 6228-04-1072 The samples were analyzed for nitrate -nitrogen in accordance with EPA Methods 353.2-354.1. Additionally, the samples were analyzed for ammonia at the request of NCDENR. The analytical results are summarized in Table 3. A nitrate isopleth map is presented on Figure 5 (April 2004). Nitrate concentration in samples collected April 16, 2004 ranged from 0.1 mg/L (RW-4) to 200 mg/L (K65W7 "A"). Ammonia concentration in samples collected April 16, 2004 ranged from <0.10 mg/L (K65W6 "A", K65W6 `B", K65W6 "B", K65W7 `B", K65W7 "D", K65W7 "F" and K65W7 "I") to 150 mg/L (RW-4). On October 28, 2004 the indicator parameters (pH, temperature and specific conductivity) were measured at each well, prior to sample collection. The results of the field parameters are summarized in Table.2. Specific conductance of the ground -water samples ranged from 127.8 µmhos/cm (K65W7 "D") to 2,905 µmhos/cm (K65W6 "A"). Values of pH ranged from 3.64 (K65W6 `B") to 12.20 (K65W7 "L"). The temperature ranged from 14.7 °C (K65W7 "F", K65W7 "J" and K65W7 "K") to 17.0 °C (K65W6 "E"). The samples were analyzed for nitrate -nitrogen and nitrite -nitrogen in accordance with EPA Methods 353.2-354.1 and 353.2, respectively. The analytical results are summarized in Table 3. A nitrate isopleth map is presented on Figure 6 (October 2004). Nitrate concentration in samples collected October 28, 2004 ranged from <0.10 mg/L (K65W7 "F") to 150 mg/L (K65W6 "A"). Nitrite was detected in wells K65W7 "J" (0.3 mg/L) and K65W7 "K" 0.78 mg/L) during the October 28, 2004 sampling event. Nitrite was not detected in the other wells that were sampled above the laboratory reporting limit during the October 28, 2004 sampling event. Remediation System Information During this reporting period, (November 2003 — October 2004) recovery well RW-2 was in operation from December 22, 2003 through April 2, 2004. Recovery well RW-2 pumped at an average rate of approximately 57 gallons per minute (gpm). Conclusions The following conclusions can be summarized from the previous sections with regard to the ground -water sampling activities at the subject property: 4 2004 Annual Report Southern States Fertilizer Plant MACTEC Project No. 6228-04-1072 December 22, 2004 • There was a slight increase. in the nitrate concentrations in the new monitoring wells K65W7 "J", K65W7 "K" and K65W7 "L" in comparison to the previous sampling events of the wells that were replaced (K65W7 "A", K65W7 "H" and K65W7 "I"). • Nitrite has not been detected in any of the site monitoring wells above the ground -water standard of 1.0 mg/L as established in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Part .0202 since October 1993. Recommendations Based upon the results of the ground -water sampling activities, MACTEC recommends the following: • Continuation of semi-annual ground -water sampling for the site monitoring wells in April and October of each year. • Submittal of an annual report by November 30 of each year. • Continuation of pulsed pumping for the ground -water remediation system.

(Southern States), MACTEC Engineering and Consulting, Inc., formerly Law Engineering and Environmental Services, Inc. (MACTEC) has previously had discussions with you in connection with the proposed realignment of US 70 through our client's property located in Statesville, North Carolina (see Figure 1). This proposed realignment of US 70 has necessitated that North Carolina. Department of Transportation (NCDOT) acquire a right-of-way through our client's property at Statesville (see Figure 2). This right-of-way will encompass an area within which three of our monitoring wells and one of the recovery. wells (i.e., RW-4; see Figure 2) are located at the site. Therefore, the purpose of this letter is to request permission to abandon these four wells shown on Figure 2 and replace themin proposed new locations north of both their existing locations and of the proposed NCDOT right- of-way. MACTEC proposes to disconnect the electrical systems at the recovery well and remove them (i.e., control panel, pump, etc.) prior to the commencement of the proposed abandonment of these four wells. Each well will be sounded for a measurement of the total depth prior to abandonment. Each well will be disinfected using a calcium hypochlorite solution containing approximately 70% chlorine. Abandonment of these wells will be completed by removing/cutting down the well casing to ground surface and backfilling each borehole with cement/bentonite grout mix. This grout mix will be placed within the well using a tremie pipe placed to the bottom of each well. Each well will be grouted from the bottom to. the top. Upon achieving a return of the grout mix at the ground surface the tremie pipe will be removed from the well. Since the commencement of the ground -water recovery system at this site, the recovery capability of the system has been appreciably less (i.e., lower ground -water withdrawal rates) in the northern area of the constituent plume compared to the southern area of the constituent plume. Therefore, MACTEC recommends that these monitoring wells and therecovery well be replaced on the north side of the proposed NCDOT right-of-way. Hence, the new location for the monitoring wells and recovery well shall be north of the proposed alignment for US 70 and within 50 feet of the existing ground -water discharge line from RW-2 and RW-4, and the electrical conduit line. The proposed locations for the replacement wells are shown in Figure 2. MACTEC Engineering and Consulting 2801 Yorkmont Road, Suite 100 • Charlotte, NC 28208 704-357-8600 • Fax: 704-357-8638 Ms. Amber Lindon, P.G. Southern States - Statesville, NC July 29, 2004 The drilling of these wells shall be preceded with a soil boring using auger drilling with blow counts and collection of soil samples for characterizing the subsurface formations. Soil samples will be obtained every 5 feet to auger refusal from the borehole employing split -spoon sampling techniques. These soil samples will be used to describe the soils encountered in.the boring. The auger drilling shall continue to auger refusal. Estimated depth to auger refusal is 120 feet. The results of the drilling of this borehole will be used to determine the depths of the proposed monitoring wells. Summary details of the existing wells and the identification of the proposed replacement wells are as follows: Well Identification Casing Diam. (ins.) Depth (feet) Proposed Well ID RW-4 6 103 RW-6 K65W7"A" 2 42 K65W7"J" K65W7"H" 4 110 K65W7"K" K65W7"I" 4 200 . K65WT L' The borehole shall be converted to new replacement monitoring well K65W7"K". The borehole will be reamed out to 10-inch diameter to the top of rock. A 4-inch diameter solid PVC casing will be installed to the top of rock. This casing shall be grouted in place by tremie pipe from bottom to ground surface. The grout around the casing will be allowed to set for 24 hours. Following that, a 10-foot corehole will be cored using NQ core barrels below the bottom of the casing. The core will be retained in a core box for characterization by a registered geologist. Following the completion of the mid -depth monitoring well, we propose to drill an 8-inch diameter borehole for shallow monitoring well (i.e., K65W7"J") to an estimated depth of 65 feet below ground surface. This depth will be determined from the soil boring described previously. A 2-inch diameter 10-foot long 0.010" slotted Schedule 40 PVC well screen with solid PVC well casing will be installed to ground surface. A fine sand will be placed around the well screen to two feet above the top of the well screen by tremie pipe. Two -feet of bentonite shall be placed above the sand pack. The annulus will be grouted with cement/bentonite mix from the bottom to ground surface by tremie pipe. The last monitoring well (i.e., K65WT L') will be drilled with a 12-inch diameter borehole to the top of rock, an estimated depth of 120 feet below ground surface. An 8-inch steel or PVC casing will be installed to the 120-foot depth and grouted from the bottom.to ground surface by tremie pipe. A 6-inch diameter bore hole will be air drilled to an approximate depth of 180 feet below ground surface. A 4-inch diameter Schedule 40 solid PVC well casing will be installed to ground surface. The annulus will be grouted with cement/bentonite mix from bottom to top by tremie pipe. The grout seal around the casing will be allowed to set for 24 hours. Subsequently a 20- foot.NQ hole will be cored below the bottom of casing. This core will be retained in a core box for characterization by a registered geologist. All three monitoring wells will be finished with above ground aluminum locking protective covers. Each of these three monitoring wells will be developed for a minimum of two 'hours either by pump or air. Based on the findings from the installation of the three monitoring wells a depth for the recovery well will be selected. Subsequently a 14-inch diameter hole will be drilled to a depth of 150 feet below ground surface. A 6-inch diameter 100-foot long 0.010" wire wound Stainless Steel well screen with solid steel well casing will be installed to ground surface. A fine sand will be placed Ms. Amber Lindon, P.G. July 29, 2004 Southern States - Statesville, NC around the well screen to 2 feet above the top of the well screen by tremie pipe. Two -feet of bentonite shall be placed above the .sand pack. The annulus will be grouted with a cement/bentonite mix from the bottom to ground surface by tremie pipe. This well will be the replacement well RW-6. Subsequently Recovery Well RW-6 will be developed for a minimum of two hours. The equipment associated with the recovery well (i.e., vault, piping, electrical, control panel, pump, etc.) will be placed within and around Recovery Well RW-6. The pump discharge will be connected to the existing discharge line. A sampling port and flow meter will be connected to the discharge line. The power will be tapped from the existing power line and run in a conduit to the vault adjacent to RW-6. The recovery system will be tested prior to demobilization from the site. A driller certified in North Carolina will install these wells. Following their completion, the location of.these wells will be surveyed. Upon the completion of the survey MACTEC will submit the abandonment forms to NCDENR and a set of well completion forms for the new wells.

Director Division of Water Quality GROUNDWATER SECTION September 17, 2002 RE: Report Review and Site Reranking Southern States Facility (Wayside Estates) GW Incident No. 5038 Iredell County, N.C. On May 13, 2002, I received a "Three Year Monitoring Report" for the subject site. On August 23, 2002, I received an updated water supply well survey. Thank you for your submission Of this information. I have completed my review of both reports. In response to the updated well survey, I have reranked the site. The current site ranking is 90 B. This ranking increases the level of regulatory oversight. It has no effect on groundwater clean-up requirements. During my review of the monitoring report, 1 noted that it was well organized and written. Based upon my review of the report, I am requesting that you continue semi-annual monitoring through at least spring 2003. Due to the ongoing drought, I am requesting that the spring 2003 sampling event be conducted at least one month after the remediation system has been turned off to allow the water table to return to non -pumping levels. This sampling event, at the approximate time of the seasonal high water table, will afford the best opportunity to collect data from the largest number of wells. During this sampling event, I request that you analyze all samples for ammonia in addition to nitrate. If you think that it would be beneficial for comparison purposes, you may also conduct a sampling event immediately prior to system shutdown in March/April 2003. You may complete this sampling event in addition to, or in lieu of the October/November 2002 sampling event. After the results of the spring 2003 sampling event have been reviewed, I would like to meet with you and Matt Gustis at the site. During our visit, I would like to discuss the following: 1. Options that may allow for operation of the recovery system throughout the year; 2. The possibility of increasing groundwater recovery in the vicinity of recovery well RW- 5; 3. The possibility of reducing the groundwater recovery in the vicinity of recovery well RW-1; 4. The relocation of wells due to the NC DOT road project; 5.

(MACTEC) and Southern States Cooperative, Inc. are pleased to submit this Meeting Notes — March 5, 2003 Site Visit for the Southern States facility. The following individuals attended the March 5, 2003 meeting held at the Southern States fertilizer facility located in Statesville, North Carolina: Matt Heller, P.G. Division of Water Quality, NCDENR Jim Wright, P.E. Southern States Cooperative, Inc. Vance Dann Southern States Cooperative, Inc. Matthew Gustis, P.E. MACTEC After introductions, Matt Heller stated that he would like to walk the site to see the location of the current remediation system, the former ponds, and the area to be impacted by future North Carolina Department of Transportation (NCDOT) construction activities. Additionally, Matt Heller stated that he would like to discuss the issues brought up in his Report Review and Site Reranking correspondence dated September 17, 2002. Mr. Gustis described the current operation of the ground -water recovery system. It consists of three pumping wells (RW-2, RW-4, and RW-5), a pH adjustment holding tank, and a National Pollutant Discharge Elimination System (NPDES) permit to discharge the effluent to the waters of North Carolina. Mr. Gustis continued to explain the historical operation of the system and the relative efficiency of each well. Recovery Well RW-5 is installed to a total depth of 70 feet below grade with a screened interval from 50-feet to 70-feet below grade which extends into the top ten feet of the partially weathered rock. Recovery Well RW-5 maintains a.pumping rate of 1 gallon per minute (gpm). Recovery Well RW-4 is installed to a total depth of 103 feet below grade with a screened interval from 28-feet to 103-feet below grade which extends into the top ten feet of fractured bedrock. Recovery Well RW-4 maintains a pumping rate of 4 to 8 gpm. Recovery Well RW-2 is installed to a total depth of 162 feet below grade with a 6-inch open hole borehole extending approximately 129 feet into fractured bedrock. RW-2 maintains a pumping rate of 50 to 60 gpm. The system is operational from November 1 through March 31. It is shut down during the summer months due to historically high concentrations of ammonia which have exceeded the NPDES permit limitations. Mr. Heller questioned the storage and handling processes at the facility. Jim Wright stated that Southern States currently mixes and stores fertilizers at the property. All process water is obtained through an on -site water supply well and stored in a water tank. This process water is MACTEC Engineering and Consulting, Inc. 2801 Yorkmont Road Suite 100 • Charlotte, NC 28208 704-357-8600 • Fax: 704-357-8638 Serving the Charlotte area for over 50 years A_ r Meeting Minutes — March 5, 2003 Site Visit March 20, 2003 Southern States Fertilizer Facility MACTEC Project No. 30150-6-1318 recirculated within the plant without exterior discharge. Historically, discharge water was discharged into holding ponds located near the southwestern portion of the property. Mr. Heller inquired about the on -site water supply well. Later discussions with Danny Rose of Southern States indicated that the water supply well can pump a capacity of 65,000 gallons per day (gpd) and is 260 feet deep. Typically, the facility utilizes approximately 30,000 gpd during the peak season. We further discussed the proposed NCDOT construction activities at the facility. Mr. Gustis explained that the NCDOT will be constructing an expansion of Highway 70 through a portion of the property. Recovery Well RW-4 and Monitoring Wells K65W7"A," K65W7"H," and K65W7"I" are within the proposed right-of-way and will have to be abandoned and reinstalled. MACTEC, as requested by the NCDOT, has submitted a proposal to abandon and reinstall the aforementioned monitoring and recovery wells and to install a conduit underneath the proposed roadway to reroute the discharge piping for RW-2. MACTEC is still coordinating with the NCDOT on these issues. We discussed options for operation of the recovery system throughout the year. Mr. Heller would like Southern States to perform their next semi-annual sampling event at the end of April 2003, approximately one month after system operations have ceased. At this time he would like to sample for ammonia in addition to nitrates and nitrites from the monitoring and recovery wells. An evaluation can be made at a later time as to the benefit of operating the system year round. Mr. Gustis pointed out that MACTEC's findings in their Three Year Monitoring Report, dated May 9, 2002, indicated that the benefits of seasonal pumping were similar to those of continuous pumping. Based upon nitrate mass extraction rates per gallon of 150.8 kilograms per million gallons for continuous pumping versus 135.0 kilograms per million gallons for seasonal pumping and the fact that nitrate extraction rates decline asymptotically with increased time of continuous pumping, seasonal pumping appears to be beneficial. We discussed the possibility of increasing ground -water recovery from RW-5. Mr. Gustis stated that RW-5 has historically pumped at a rate of approximately one gallon per minute. It apparently was never installed to a proper depth when the system was installed by Canonie Environmental. Mr. Gustis presented the option of reinstalling RW-4 further north due to the NCDOT activities and closer to RW-5 to help capture the higher concentrations of nitrates. Mr. Heller mentioned the possibility of extending RW-5 deeper. However, as a first step, he was interested in relocating RW-4 as an option for optimizing the recovery system. We also discussed the possibility of reducing the recovery from RW-2. Mr. Heller stated to use our judgment on this issue. Mr. Heller questioned whether or not the off -site water supply wells located west of the facility have been sampled. Mr. Gustis stated that to the best of his knowledge they have not. Mr. Heller may sample those wells at a later time. Mr. Heller also discussed the option of operating the system year round and using the discharge in the summer months for plant process water. This option may or may not be feasible and would have to be evaluated by Southern States. Actions that Mr. Heller would like Southern States to take include: Collecting ground -water samples from the monitoring and recovery wells for nitrates, nitrites, and ammonia in April 2003; Submitting an annual report summarizing the October 2002, and April and October 2003 semi-annual sampling events by November 30, 2003; Continuing ground -water monitoring on a semi-annual basis; 2 Meeting Minutes — March 5, 2003 Site Visit Southern States Fertilizer Facility MACTEC Project No. 30150-6-1318 March 20, 2003 • Continuing reporting on a annual basis with the report to be submitted by November 30 of each year; • Continuing seasonal system operation between November 1 and March 31 of each year; • Evaluating where the most efficient location of RW-4 would be to increase ground water pumping rate in the vicinity of RW-5.

OF ENVIRONMENT AND NATURAL RESOURCES RECEIVED DEC 12003 MOORESVILLE REGIONAL OFFICE DWQ-GROUNDWATER SECTION On behalf of Southern States Cooperative, Inc. (Southern States), MACTEC Engineering and Consulting, Inc., formerly Law Engineering and Environmental Services, Inc. (MACTEC) has completed the second semi-annual ground -water sampling event for 2002 and the first and second semi-annual ground -water sampling events for 2003 at the subject site (Figure 1). The work was performed according to MACTEC's Meeting Notes — March 5, 2003 Site Visit, dated March 20, 2003. This report briefly outlines our recently completed field activities and the results of the ground -water analyses. Background The previous schedule of sampling and reporting consisted of semi-annual sampling and analysis from selected site monitoring wells for nitrite and nitrate. The semi-annual sampling was performed during April and October of each year. Ground water was recovered from recovery wells RW-2 and RW-4 five months of the year (November through March), followed by no pumping for seven months (April through October). Cyclical pumping allows ground water to recover in all of the monitoring wells during the time when the recovery wells are not operating, thus enabling them all to be sampled. The monitoring wells are sampled and analyzed for nitrite and nitrate. Recovery wells are also sampled for nitrite and nitrate but only during the time when they operate., As a result of the Report Review and Site Reranking correspondence dated. September.17, 2002, the North Carolina Department of Environment and Natural Resources (NCDENR) requested the MACTEC Engineering and Consulting 2801 Yorkmont Road, Suite 100 e Charlotte, NC 28208 704-357-8600 • Fax: 704-357-8638 2002 — 2003 Annual Report November 26, 2003 Southern States Fertilizer. Plant MACTEC Project No. 30150-6-1318 spring 2003 semi-annual sampling event be conducted approximately one month after. the recovery system was shut down to allow the ground -water table .to return to non -pumping elevations. Additionally, NCDENR requested the analysis of ammonia in addition to nitrate and nitrite. On March 5, 2003, a site meeting was held.at the facility between representatives of Southern States, MACTEC, and Mr. Matt Heller of NCDENR. At this time we discussed the.current operation of the recovery system and sampling and reporting schedule. Mr. Heller requested continuation of semi-annual sampling from the site monitoring wells in April and October of each year and annual reporting by November 30 of each year. Additionally, he requested an annual report by November 30, 2003 summarizing the results of the October 2002, May 2003, and October 2003 sampling events. Field Sampling On October 18, 2002, May :2, 2003, and October 17, 2003, MACTEC collected representative samples of ground water from on -site monitoring wells (Figure 2). Depths to ground water were measured at each monitoring well prior to well purging and are summarized in Table :1. Ground- water flow for the site is illustrated on the ground -water contour maps for each sampling event (Figures 3, 4, and 5). The contours represent equipotential lines for the respective set of data. The natural direction of ground -water flow is:toward the south-southwest. Field sampling procedures followed those normally employed to. gather ground -water samples from monitoring wells and were outlined in the approved Corrective Action Plan (CAP) of January 28, 1994 for ground -water recovery. Each well was first purged to bring fresh formation water into the well. A volume of water equal to at least three well volumes (or to dryness twice) was removed from each well prior to sampling. Disposable bailers and new polypropylene rope were used to collect each sample. Field indicator parameters of pH, temperature, and specific conductivity were measured with calibrated meters after purging each well volume of ground water. The semi-annual ground -water monitoring program consisted of sampling the following wells: K65W6 "A" K65W6 "E" K65W7 "D" K65W7 "H" RW-5 K65W6 `B" K65W7 "A" K65W7 "E" K65W7 "I" K65W6 "C" K65W7 `B" K65W7 "F" RW-2 K65W6 "D" K65W7 "C" K65W7 `°G" . RW-4 W 2002 — 2003 Annual Report November 26, 2003 Southern States Fertilizer Plant MACTEC Project No. 30150-6-1318 During .the October 18, 2002 sampling event, Wells K65W6 `B", K65W6 "D", K65W7 "A", K65W7 `B", K65W7 "C", K65W7 "E", and K65W7 "G" did not have sufficient water to purge or sample. During the May 2, 2003 sampling event, Wells K65W6 "D", K65W7 `B", K65W7 "C", and K65W7 "E" did not have sufficient water to purge or sample. During the October 17, 2003 sampling event, Well K65W6 "D" did not have sufficient water to purge or sample and Well K65W7 "E" could not be located. Monitoring well K65W6 "C" was covered with fill material due to previous construction activities at the site, and as a result was inaccessible for future reporting periods. Therefore, this well could not be purged or sampled during the reporting period. Ground -water samples were placed in laboratory provided containers and delivered on ice to Pace Analytical Laboratories, Inc. in Huntersville, North Carolina. Ground -water temperature, specific conductance, and pH were measured in the field at the time of sampling and are provided in Table 2. Analytical Results On October 18, 2002 the indicator parameters (pH, temperature and specific conductivity) were measured at each well, prior to sample collection. The results of the field parameters are summarized in Table 2. Specific conductance of the ground -water samples ranged from 124.7 µmhos/cm (K65W7 "D") to.3,230 µmhos/cm . (K65W6 "A").. Values of pH ranged from 5.49 (K65W7 "H") to 7.48 (K65W7. "F"). The temperature ranged from 15.6 'C (K65W7 "F") to 19.3 °C (RW-2). The samples were analyzed for nitrate -nitrogen and nitrite -nitrogen in accordance with EPA Methods 353.2-354.1 and 353.2, respectively. The analytical results are .summarized in Table 3. A "nitrite concentration map is presented on Figure 6 (October 2002) and a nitrate isopleth map is presented on Figure 7 (October 2002). Nitrite results are presented as a concentration. map because there are insufficient data to generate contours for nitrite concentration. Nitrate concentration in samples collected October 18, 2002 ranged from 2.4 mg/L (K65W7 "D".) to 170 mg/L (K65W6 "A"). Nitrite was not detected in any of the wells above the laboratory reporting limit during the October 18, 2002 sampling event. Q 2002 — 2003 Annual Report Southern States Fertilizer Plant MACTEC Project No. 30150-6-1318 November 26, 2003 On May 2, 2003 the indicator parameters (pH, temperature and specific conductivity) were measured at each well, prior to sample collection. The results of the field parameters are summarized in Table 2. Specific conductance of the ground -water samples ranged from 103.5 µmhos/cm (K65W7 "D") to 3,480 µmhos/cm (K65W6 "A"). Values of pH ranged from 3.57 (K65W7 "A") to 7.60 (K65W7 "I"). The temperature of the ground -water samples ranged from 13.6 °C (K65W7 "G") to 20.8 °C (RW-4). The samples were analyzed for nitrate -nitrogen and nitrite -nitrogen in accordance with EPA Methods 353.2-354.1 and 353.2, respectively. Additionally, the samples were analyzed for ammonia at the request of NCDENR. The analytical results are summarized in Table 3. A nitrite concentration map is presented on Figure 8 (May 2003) and a nitrate isopleth map is presented on Figure 9 (May 2003). Nitrite results are presented as a concentration map because there are insufficient data to generate contours for nitrite concentration. Nitrate concentration in samples collected May 2, 2003 ranged from 1.3 mg/L (K65W7 "G") to 230 mg/L (K65W7 "A").... Nitrite was not detected in any of the wells above the laboratory reporting limit during the May 2, 2003 sampling event, except K65W7 "H and RW-4, which contained 0.054 mg/L and 0.12 mg/L, respectively. Ammonia concentration in samples collected May 2, 2003 ranged from <0.10 mg/L (K65W6 "A", K65W6 `B", K65W "6E", K65W7 "F", K65W7 "G", and K65W7 ``I") to 150 mg/L (RW-4). On October 17, 2003 the indicator parameters (pH, temperature and specific conductivity) were measured at each well, prior to sample collection. The results of the field parameters are summarized in Table 2. Specific conductance of the ground -water samples ranged from 149.3 µmhos/crim (K65W7 "D") to :3,180 µmhos/cm (K65W6 "A"). Values of pH ranged from 3.92 (K65W7 "C") to 8.30 (K65W6 "E"). The. temperature of the ground -water samples ranged from 13.9 °C (K65W7 "B") to 18.1 °C (K65W6 "B"). The samples were analyzed for nitrate -nitrogen and nitrite -nitrogen in accordance with EPA Methods 353.2-354.1 and _353.2, respectively. Additionally, the samples were analyzed for ammonia at the request of NCDENR. The analytical results are summarized in Table 3. A nitrite concentration map is presented on Figure 10 (October 2003) and a nitrate isopleth map is presented on Figure 11 (October 2003). Nitrite results are presented as a concentration: map because there are insufficient data to generate contours for nitrite _ concentration. Nitrate 4 2002 — 2003 Annual Report November 26,.2003 Southern States Fertilizer Plant MACTEC Project No. 30150-6-1318 concentration in samples collected October 17. 2003 ranged from <0.050.mg/L (K65W7 "D") to 84 mg/L (K65W6 "A"). Nitrite was not detected in any of the wells above the laboratory reporting limit during. the October 17, 2003 sampling event. Ammonia concentration in samples collected October 17, 2003 ranged from <0.10 mg/L (K65W6 "A",. K65W6 "B", K65W "W', K65W7 "B", K65W7 "D", K65W7 "F", K65W7 "G", and K65W7 "I") to 9.1 mg/L (K65W7 "C"). Remediation System Information During this reporting period, (April 2002 — October 2003) recovery wells RW-2 and RW-4 were in operation from December 17, 2002 through March 31, 2003. Recovery well RW-2 pumped at an average rate of. approximately 48 gallons per minute (gpm). Recovery well RW-4 pumped at an average rate of approximately 4 gpm while in operation. Conclusions The following conclusions .can be summarized from the previous sections with regard to the ground -water sampling activities at the subject property: • There is an overall general .trend toward decreasing nitrate concentrations for the monitoring wells across the site. • Based upon the nitrite concentrations, nitrite is not a constituent of concern for this site. • Nitrite has not been detected in any of the site monitoring wells above the ground -water standard of 1.0 mg/L as established in. Title 15A of the North .Carolina Administrative Code, Subchapter 2L, Part.0202 since October 1991. • Increasing ground -water elevations resulting from rainfall in late 2002 and early 2003 allowed MACTEC to collect samples from site monitoring wells that have historically been dry (K65W6 "B", K65W7 "A", K65W7 "B", and K65W7 "C"). Recommendations Based upon the results of the ground -water sampling activities, MACTEC recommends the following: • Continuation of semi-annual ground -water sampling for the site monitoring wells in April and October of each year. 5 2002 — 2003 Annual Report November 26, 2003 Southern States Fertilizer Plant MACTEC Project No. 30150-6-1318 • Discontinuance of analysis of the semi-annual .ground -water samples for nitrite. e Submittal of an annual report by November 30 of each year. • Continuation of pulsed pumping for the ground -water remediation system. • Due to proposed NCDOT construction activities at the facility which involve an expansion of Highway 70 through a portion of the property, Recovery Well RW-4 and Monitoring Wells K65W7"A," K65W7"H," and K65WT I' are within the proposed right-of-way and will have to be abandoned and reinstalled. MACTEC recommends relocation of RW-4 north/northeast closer to RW-5 in, order to improve system efficiency and recovery of higher concentrations of nitrates.

INTRODUCTION Southern States Cooperative, Inc. (Southern States) owns and operates a fertilizer plant located on U.S. Highway 70 approximately six miles east of Statesville, North Carolina (Figure 1). The facility was reportedly constructed in the 1950s. Southern States purchased the facility from W.R. Grace & Co. 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 premixed, bagged products on pallets. These products are sold directly to consumers without modification by Southern States. The manufacturing facility is currently self-contained; process water is recirculated within the plant without exterior discharge. This is possible due to the use of air scrubbers to reduce smokestack emissions. The scrubbers utilize a "wet" system and the scrubber water is consumed in the granulation process. Prior to changes in the scrubber design approximately twenty years ago, process water was discharged from time.to time. This process water was discharged to two former ponds located approximately 1,000 feet southwest of the plant. Two other ponds were reportedly closed. One of these ponds was located east of the plant and was reportedly closed approximately thirty years ago. The other pond was located 300 feet southwest of the plant and was reportedly closed in the mid-1980's. The ponds located around the plant were reportedly unlined. Therefore, the discharge of process water to some of these ponds did create a situation conducive for potential leakage of these process waters into the subsurface media. In 1989, Southern States retained Law Engineering and Environmental Services, Inc. (LAW) to assist with the evaluation and remediation at the facility. On December 12, 1989, the North Carolina Department of Environment and Natural Resources (NCDENR) (formerly the Department of Environment, Health and Natural Resources [NCDEHNR]) issued a Notice of Violation (NoV) for the site. The NoV stated that excessive concentrations of nitrate and/or nitrite had been discovered in two wells located at the site. Additional assessment was required by NCDENR to be conducted at the site. W.R. 1-1 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 Grace & Co., the primary responsible party, retained Canonie Environmental Services Corporation (Canonie) to monitor the environmental assessment work for the site. Canonie subsequently contracted LAW to assist with the fieldwork associated with the assessment of the site. LAW performed the field work for assessing the extent of the leakage from the .two aforementioned ponds into the subsurface media. Monitoring wells were installed across the site, south of the plant, and were screened at various depths below ground surface. The locations of the monitoring wells are shown on Figure 2. I LAW performed several hydraulic tests and an aquifer test in October 1991 at the site under the direction of Canonie in order to acquire the data for the design of the remedial system proposed for the site. On January 28, 1994, Canonie submitted a corrective action plan for ground -water recovery at the subject property. Correspondence from NCDENR, dated March 18, 1994, included review comments for the plan and stated that semi-annual sampling should be conducted until the corrective action system was operational. Accordingly, LAW collected semi-annual ground -water samples during 1994. The ground- water recovery system was installed in late 1994. The recovery system became operational in January 1995. 1-2 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 2. BACKGROUND Ground -water recovery operations began in January 1995; however, the pH of the discharge water was below National Pollutant Discharge Elimination System (NPDES) permit limitations. Therefore, a sodium hydroxide caustic agent was introduced into the wastewater stream in an effort to raise the pH. Ground -water recovery resumed on June 29, 1995. The ground -water recovery system consisted of three recovery wells (i.e., RW-2, RW-4 and RW-5). The locations of these recovery wells are shown on Figure 2. Recovery Well RW-2 is located near the southern property boundary and consists of an open hole in fractured bedrock from a depth of 37 feet below ground surface to a total depth of 162 feet below ground surface. Recovery Well RW-4 was installed approximately 650 feet north of Recovery Well RW-2. Recovery Well RW-4 consists of a 75-foot long screen spanning the bottom ten feet of the residual soil, partially weathered rock and the upper ten feet of the fractured bedrock. The top of the screen is 28 feet below ground surface and Recovery Well RW-4 has a total depth of 103 feet below ground surface. Recovery Well RW-5 was installed approximately 160 feet south-southeast of the plant. Recovery Well RW-5 consists of a 20-foot long screen spanning the bottom ten feet of the residual soil, and the top ten feet of the partially weathered rock. The top of the screen is 50 feet below ground surface and the total depth of Recovery Well RW-5 is approximately 70 feet below ground surface. Because of the elevated ammonia concentrations present in the recovered ground water from Recovery Well RW-4, the recovered ground water discharged to Fourth Creek did not meet the ammonia discharge limits established by NCDENR within the NPDES permit. Therefore, the pumping schedule for the recovery wells was altered to increase the potential for meeting the discharge limits during the summer months (i.e., April 1 through October 31). Ground water was recovered continuously from two recovery wells (RW-2 and RW-5) throughout the entire year and from three recovery wells (RW-2, RW-4 and RW-5) from November through March. Recovery Well RW-4 was not pumped from April 1 through October 31 due to the NPDES permit restrictions on ammonia. The monitoring wells at the site were sampled on a semi-annual schedule, with sampling performed during May and November. of each year. 2-1 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 In a letter mailed to Southern States, dated November 5, 1998, NCDENR raised some concerns about the ground -water remediation system. As a result of this letter 'a meeting was held on December 16, 1998 at the NCDENR office in Mooresville, North Carolina. Representatives from Southern States, W.R. Grace & Co., LAW and NCDENR were present at this meeting. Several issues were discussed at this meeting in regard to the ground -water remediation system at the Southern States Statesville facility. These issues were as follows: ♦ the NCDENR ranking of the site at 150/B was questioned based on a more recent water well survey; ♦ revised operation of the ground -water remediation system was proposed; ♦ the feasibility of performing a risk assessment for this site was discussed; and ♦ a request to abandon RW-1 and RW-3 was raised by W.R. Grace & Co. Based on the discussions during the meeting, the latter two issues were dropped from further pursuit at that time. However, in LAW's Proposed Change to Ground -Water Remediation System Operating and Reporting Schedule, dated January 27, 1999, the discussions pertaining to the first two issues were presented in writing and submitted to NCDENR as a basis for reviewing the site ranking and revising the operation of the ground -water remediation system. In a letter from NCDENR dated February 17, 1999 the ranking of the site was revised to 30/1) and NCDENR agreed with the proposed revised operation of the ground -water remediation system. The goal of the revised operational plan for the ground -water remediation system was to implement pulsed pumping of the system, rather than continuous pumping. This approach was proposed for the following reasons: 1. To determine whether or not pulsed pumping will influence recovery efforts more effectively than continuous pumping; 2. To allow ground water to recover in all of the monitoring wells during the time when the recovery wells are not operating, thus enabling all of the monitoring wells to be sampled; and 3. To eliminate the discharges of recovered ground water with ammonia concentrations exceeding the NPDES discharge limits. 2-2 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 The pulsed pumping approach involved operation of the three recovery wells (RW-2, RW-4, and RW-5) for approximately five months of the year (November through March), followed by a period of seven months (April through October) with no pumping. Recovery wells are also sampled for nitrite and nitrate, but only during the time when they operate. The semi-annual sampling schedule for the monitoring wells was altered to match the pumping schedule. The months in which samples were _to be collected changed from November and March to October and April. The October sampling event allows for samples to be collected after the system has been off for seven months prior to the recommencement of the pumping. The April sampling event allows for samples to be collected after the system has been operating for five months. Reporting was proposed to change from a semi-annual basis to an annual basis with annual reports submitted to the NCDENR after the October sampling event. The pulsed pumping schedule would be continued for three years, at the end of which time a more comprehensive report would be submitted to NCDENR with comments and recommendations based on the results from the three years of pulsed pumping. A three-year period was planned because it was thought that would allow enough time for data to be collected to better evaluate the impact of the pulsed pumping and ground -water remediation at this site. This report was prepared pursuant to the NCDENR letter approving the pulsed pumping schedule outlined in LAW's Proposed Change to Ground -Water Remediation System Operating and Reporting Schedule, dated January 27, 1999. The purpose of this report is to present a summary of the three years of pulsed pumping of the ground -water remediation system. 2-3 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 3. OPERATIONAL ACTIVITIES _ As discussed in Section 2 the ground -water remediation system at the Southern States facility i I commenced operations in January 1995. The period of continuous pumping was continued through to the end of March '1999. The pulsed pumping schedule began on April 1, 1999 and has continued through to the end of March 2002. Further details of the operation of the ground -water remediation system are provided in Section 3.3. Both before the installation of the ground -water remediation system and during the operation of the ground -water remediation system the site has been monitored on a semi-annual basis. Monitoring of the ground -water remediation system consisted of measuring depths to ground water in each of the monitoring wells and the collection of ground -water samples (see Section 3.1) for analysis in the laboratory for nitrate and nitrite (see Section 3.2). 3.1 Monitoring Activities For each semi-annual sampling event LAW mobilized to the subject property to collect representative samples of ground water from the on -site monitoring wells (Figure 2). , Depths to ground water were measured at each monitoring well prior to well purging and are summarized for three events in Table 1. These three events were selected to represent the following conditions: • pre-remediation "natural' conditions (February 18, 1991), which were approximately four years prior to the commencement of continuous pumping; - • the end of the period of continuous pumping (March 30, 1999); and • the end of the period of pulsed pumping (March 28, 2002). Ground -water flow for the site prior to the commencement of pumping in 1995 is illustrated on the ground- water contour map (Figure 3). Ground -water contours and flow for the site at the end of the period of continuous pumping are shown on Figure 4 and at the end of the period of pulsed pumping are shown on Figure 5. The contours represent equipotential lines for the respective set of data. The natural direction of ground -water flow is toward the south-southwest. Field sampling procedures followed those normally used to gather ground -water samples from monitoring wells and were those outlined in the approved corrective action plan of January 28, 1994 for ground -water recovery. Each well was first purged to bring fresh formation water into the well.. A volume of water equal to at least three well volumes (or to dryness twice) was removed from each well 3-1 Southern. States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 prior to sampling. Disposable bailers and new polypropylene rope were used to collect each sample. Indicator parameters (specific conductance, pH and temperature) were measured in the field and have been reported in previous annual reports. Field indicator parameters of pH, temperature, and specific conductivity were measured with calibrated electronic meters after purging each well volume of ground water. Besides the three active recovery wells located at the site there are fourteen monitoring wells that are regularly sampled during each semi-annual sampling event. One of the goals of changing the operation of the ground -water remediation system to pulsed pumping was to permit the ground water in several of the monitoring wells to recover from the lowered water table induced by the pumping prior to activating the ground -water remediation system each November. The semi-annual ground -water monitoring program consisted of sampling the following wells: K65W6 "A" K65W6"B" K65W6"C" K65W6"D" K65W6 "E" K65W7 "A' K65W7 `B" K65W7 "C" K65W7"D" K65W7"E" K65W7"F" K65W7"9" K65W7 "H" K65W7 "P' RW-2 RW-4 RW-5 During the period of continuous pumping, seven of the monitoring wells (i.e., K65W6`B", K65W6"D", K65W7"C", K65W7"D", K65W7"B", K65W7"F", and K65W7"G") did not have sufficient water to purge and/or sample. One other monitoring well (i.e., K65W7"B") did not have sufficient water to purge and/or sample for the latter half of the period of continuous pumping. Additionally during the last two sampling events of this period Monitoring Well K65W7"A" did not have sufficient water to purge and/or sample. Therefore, by the end of the period of. continuous pumping nine of the fourteen monitoring wells were not dependable for acquiring sufficient water to purge and/or sample. Monitoring Well K65W6 "C" was covered with fill material due to construction activities at the site, and as a result was inaccessible for future reporting periods. Therefore, this well could not be purged or sampled during the entire period of pulsed pumping. During the period of pulsed pumping four of the monitoring wells (i.e., K65W6"D", K65W7`B", K65W7"C", and K65W7"E") did not have sufficient water to purge and/or sample. Of the five monitoring wells that were sampled at each sampling event during the period of continuous pumping, one was covered due to construction activities (K65W6 "C") and the other four were continuously sampled 3-2 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 during the period of pulsed pumping (i.e., K65W6"A", K65W6"E", K65W7"H", and K65W7"P'). The switch to pulsed pumping enabled intermittent sampling of four of the remaining five monitoring wells and continuous sampling of one monitoring well (K65W7"D"). Additionally, during the period of the pulsed pumping, rainfall in North Carolina has been significantly lower than the average rainfall. Thus groundwater elevations have been exhibiting an overall decline, thereby potentially reducing the number of monitoring wells with sufficient ground water available for sampling purposes. Upon collection of the ground -water samples, they were placed in laboratory provided containers and delivered to a North Carolina certified laboratory (i.e., Pace Analytical Services, Inc. in Huntersville, North Carolina and Prism Laboratories, Inc. in Charlotte, North Carolina). 3.2 Laboratory Analytical Results As required by the corrective action plan, the samples were analyzed for nitrate -nitrogen and nitrite - nitrogen in accordance with EPA Methods 353.2-354.1 and 353.2, respectively. The analytical results are summarized in Table 2 and the laboratory report from the March 29, 2002 event has been included as Appendix A. Of all the analytical data for nitrite from the monitoring wells at this site, only one sampling event exhibited a nitrite concentration exceeding the North Carolina Maximum Contaminant Level (MCL) of 1 milligram per liter (mg/L) as presented in Title 15A of the North Carolina Administrative Code, Section 2L, Subchapter .0202 (15A NCAC 2L.0202). This sampling event was conducted on February 10, 1993 with the ground -water sample collected from K65W7 "P'. The nitrite concentration was 9 mg/L. Both before and since then the other sixteen nitrite concentrations for this monitoring well are below the MCL and in most instances below the Minimum Detection Level (MDL). Hence, the single exceedance of the nitrite MCL is an anomalous event. Therefore, based on these results nitrite is not a concern at this site. There are two sampling events with a complete nitrate data set for the period prior to the commencement F of continuous pumping (i.e., 1/22/92 and 2/10/93). However, an inspection of the latter, data indicates that three of the nitrate concentrations (i.e., K65W6"A", K65W7"H", and K65W7"P') do not fit the overall nitrate trend for the respective monitoring well. Therefore, the nitrate data for the former sampling event was selected as being representative of the period prior to the commencement of the 3-3 Southern States Cooperative, Inc — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 sampling event was selected as being representative of the period prior to the commencement of the continuous pumping. A nitrate isopleth map for this sampling event is presented on Figure 6 (January 22, 1992). Nitrate concentrations for the sampling events at the end of each of the pumping periods (i.e., continuous — 3/30/99; and pulsed — 3/29/02) are presented on Figures 7 and 8. Fluctuations in nitrate concentrations are typical and may be related to ground -water recharge and/or seasonal variations. Trend plots for nitrate concentrations in each monitoring well are included in Appendix B. -4 3.3 Remediation System Operation The ground -water, remediation system at the Southern States facility commenced operations in January 1995. However, because of several operational problems the system was down for most of the first half of both 1995 and 1996. Only after August 1996 was the ground -water remediation system able to maintain a continuous withdrawal of ground water. The continuous ground -water withdrawal continued through to the end of March 1999 for a total period of approximately 32 months. From March 1999 to the end of March 2002 the ground -water remediation system has been operated on a pulsed pumping schedule. During the period of pulsed pumping the ground -water remediation system was pumped for a total of 14 months (there were approximately two months of downtime during startup in November 2000, though the system was pumped for an extra month). During the periods of pumping, Recovery Well RW-2 typically pumps from 50 to 60 gallons per minute (gpm). Recovery Well RW-4 typically pumps from 4 to 8 gpm and Recovery Well RW-5 approximately 1 gpm. Therefore, about 90 percent of the recovered ground water is extracted from Recovery Well RW- 2. Recovery. Well RW-4 contributes approximately 9 percent of the flow. Combining the pump rates of the three recovery wells, the total ground -water withdrawal rate ranged from 55 to 70 gpm during the periods of operation. For the period of the continuous pumping the ground -water remediation system recovered 88 million gallons of ground water. During the subsequent period of pulsed pumping approximately 29 million gallons of ground water were recovered. Based on an average flow rate per month, the ground -water remediation system recovered 2.76 million gallons per month for the period of continuous pumping and 2.07 million gallons per month for the period of pulsed pumping. 3-4 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 4. DATA INTERPRETATION The data collected during the operation monitoring visits conducted at the site over the past seven years were presented in Section 3. The assessment of the ground -water remediation system is done in two parts. In the first part the recovery operational data are reviewed in Section 4.1 in order to assess the operation of the ground -water remediation system at the Southern States facility. In the second part, Section 4.2 reviews the trend of the nitrate concentrations for the monitoring wells located at the site. 4.1 Review The goal of the ground -water remediation system is to remove nitrates from the subsurface media underlying the site. Hence, the primary purpose of this report is to assess whether the ground -water remediation system has been meeting this goal. A secondary purpose of this report is to assess the effectiveness of a continuously pumped ground -water remediation system versus a pulsed pumped system. There are a number of approaches available for reviewing the data in order to evaluate the success of meeting this goal and also, to compare the operation of a continuously pumped system versus pa pulsed pumping system. Using the nitrate concentrations for the recovered ground water from each of the recovery wells. and flow rate data, the estimated total mass of nitrate recovered through the ground -water remediation system is 17,260 kilograms. Of this total mass, 13,300 kilograms were recovered during the period of continuous pumping. Another 3,960 kilograms of nitrate were recovered during the period of pulsed pumping. In order to make a fair comparison between the two different pumping periods the nitrate mass per gallon pumped from the underlying aquifer needs to be determined from the available data. During the period of continuous pumping the average nitrate extraction rate was 150.8 kilograms per million gallons and during the period of pulsed pumping the average nitrate extraction rate was 135.0 kilograms per million gallons. The rate of nitrate extraction during the latter pumping period was reduced by 10 percent from the nitrate extraction rate for the first pumping period. However, a lower nitrate extraction rate during the latter pumping period does not necessarily mean that pulsed pumping is less effective than continuous pumping, because typically the nitrate extraction rates decline asymptotically with increased time of .continuous pumping. Therefore, a comparison of the nitrate extraction rates from the ground -water remediation system for the continuous and pulsed pumping 4-1 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 periods was indeterminate for assessing the optimum pumping approach. In a review of pulsed pumping, the United States Environmental Protection Agency (USEPA) was also unable to assess whether it was any better or worse than continuous pumping for several sites (Ref.: Evaluation of Ground -Water Extraction Remedies, Volume I — Summary Report, EPA/540/2-89/054, September 1989). 4.2 Trend Analysis The second part of the assessment of the ground -water remediation system is to summarize the trends of the nitrate concentrations in the monitoring wells. As outlined in Section 3.1 there were fourteen monitoring wells actively monitored as part of the ground water monitoring program at the site. However, Monitoring Well K65W6"C" was lost due to construction activities in 1998. A review of the nitrate concentrations, for, January 22, 1992 (prior to commencement of pumping), March 30, 1999 (end of the continuous pumping period), and March 29, 2002 (end of the pulsed pumping period) was made in order to determine overall trends. At the end of the continuous pumping period five monitoring wells exhibited a decrease in nitrate concentrations (i.e., K65W6"A", K65W6"C", K65W7"D", K65W7"H", and K65W7"P') and two monitoring wells exhibited an increase in nitrate concentrations (Le., K65W6`B" and K65W6"E") compared to January 22, 1992 concentrations. At the end of the pulsed .pumping period five monitoring wells exhibited a decrease in nitrate concentrations (i.e., K65W6"A", K65W7"D", - K65W7"F", K65W7"H", and K65W7"I") and four monitoring wells exhibited an increase in nitrate concentrations (i.e., K65W6`B", K65W6"E", K65W7"A", and K65W7"G") compared to January 22, 1992 concentrations. It should be noted that the nitrate concentration in Monitoring Well K65W7"G" is below the MCL of 10 mg/L for nitrate, except for the most recent concentration of 31 mg/L, which is an anomalous value compared to the data history for this well. Nitrate concentration plots for the monitoring wells are presented in Appendix B. 4-2 Southern States Cooperative, Inc. — Three Year Monitoring Report May 9, 2002 Statesville Facility LAW Project No. 30150-6-1318 5. CONCLUSIONS AND RECOMMENDATIONS 5.1 Conclusions The following conclusions can be summarized from the previous sections with regard to the operation of the ground -water remediation system for the Southern States facility in Statesville, North Carolina: ♦ Changing the ground -water remediation system from a continuously pumped system to a pulsed pumped system did enable more monitoring wells to be sampled than previously sampled. ♦ A total of 17,260 kilograms of nitrate have been recovered from the ground water underlying the site. ♦ A comparison of the nitrate extraction rates from the ground -water remediation system for the continuously and pulsed pumping periods was indeterminate for assessing the optimum pumping approach. ♦ Both the continuously pumped ground -water remediation system and the pulsed pumping were capable of removing nitrate from the ground water at relatively similar rates. ♦ Based on the nitrite concentrations, nitrite is not a constituent of concern for this site. ♦ There is a general trend toward decreasing nitrate concentrations for the monitoring wells across the site. 5.2 Recommendations Based on NCDENR's revised site ranking to 30/1) in a letter dated February 17, 1999, LAW recommends that consideration be given to performing a risk assessment for this site. In the event that agreement cannot be reached in performing a risk assessment, LAW recommends that the pulsed pumping of the system be continued "for another three years. LAW also recommends that the ground -water monitoring network be sampled on an annual basis during the month of October, prior to the commencement of the pumping during the winter months. The rationale for recommending annual ground -water sampling is based on a combination of the extensive monitoring well data set already available for this site, the lower ranking of the site, and the inability of acquiring a meaningful and complete data set at the end of each pumping period (i.e., March) because of the reduced ground -water elevations due to pumping. 5-1 Southern States Cooperative, Inc. — Three -Year Monitoring Report Statesville Facility LAW Project No. 30150-6-1318 TABLES May 9,2002 Southern States Fertilizer Plant - Three Year Monitoring Report May 9, 2002 LAW Project 30150-6-1318 ' TABLE 1 GROUND -WATER ELEVATION DATA SOUTHERN STATES FERTILIZER PLANT STATESVILLE, NORTH CAROLINA LAW PROJECT NO.30150-6-1318 Well Ground -Water Measurement Top of Casing Depth to Identification Date Elevation (feet) Water (feet) Elevation (feet) K65W6"A" 2/18/91 864.52 16.25 848.27 3/30/99 23.84 840.68 3/29/02 28.32 836.20 K65W6"B" 2/18/91 871.55 19.05 852.50 3/30/99 24.04 847.51 3/29/02 28.80 842.75 K65W6"C" 2/18/91 861.69 34.95 826.74 3/30/99 44.52 817.17 3/29/02 NM -- K65W6"D" 2/18/91 849.37 31.10 818.27 3/30/99 DRY < 809.45 3/29/02 DRY < 809.45 K65W6"E" 2/18/91 864.89 18.30 846.59 3/30/99 23.99 840.90 3/29/02 28.33 836.56 K65W7"A" 2/18/91 833.47 23.00 810.47 3/30/99 43.66 789.81 3/29/02 DRY < 787.17 K65W7"B" 2/18/91 821.75 15.85 805.90 3/30/99 DRY < 791.24 3/29/02 DRY < 791.24 K65W7"C" 2/18/91 809.72 14.32 795.40 3/30/99 DRY < 785.62 3/29/02 DRY < 785.62 K65W7"D". 2/18/91 800.64 7.32 793.32 3/30/99 12.12 788.52 3/29/02 12.28 788.36 K65W7"E" 2/18/91 823.70 25.61 798.09 3/30/99 DRY < 786.28 3/29/02 DRY < 786.28 Page 1 of 2 Southern States Fertilizer Plant - Three Year Monitoring Report LAW Project 30150-6-1318 TABLE 1 GROUND -WATER ELEVATION DATA SOUTHERN STATES FERTILIZER PLANT STATESVILLE, NORTH CAROLINA LAW PROJECT NO.30150-6-1318 May 9, 2002 Well Measurement Top of Casing Depth to Ground -Water Identification Date Elevation (feet) Water (feet) Elevation (feet) K65W7"F" 2/18/91 796.15 6.73 789.42 3/30/99 DRY < 766.20 3/29/02 24.00 772.15 K65W71'G" 2/18/91 795.98 6.20 789.78 3/30/99 DRY < 779.15 3/29/02 14.06 781.92 K65W7"H" 2/18/91 833.92 29.10 804.82 3/30/99 49.89 784.03 3/29/02 53.00 780.92 K65W7"I" 2/18/91 835.54 32.60 802.94 3/30/99 47.68 787.86 3/29/02 50.21 785.33 Prepared/Date: / C; . o 2 Checked/Date: (,� 9 02 NOTES: 1.

Phone: 704.875.9092 Fax.• 704.875.9091 I, along with the inorganic laboratory supervisor, reviewed the data from these two samples. For sample K65W7"G" (922178991), this sample was originally analyzed full strength; however, the results from this analytical run exceeded, the calibration range of our instrument. The sample was reanalyzed at a ten -fold dilution. The results from this analytical run were 31.4 mg/L, which is the result that was reported to you. The results from this analysis confirmed the results of the original run. With regards to sample K65W6"A" (922178959), the sample was originally analyzed full strength with the results exceeding the calibration range of the instrument. The sample was reanalyzed using a five -fold dilution. However, due to an error with the instrument software, nitrate was misidentified and was reported as < 0.50 mg/L. The nitrate data from the five -fold run still exceeded the calibration range of the instrument. Therefore, a revised report is being reissued to you with estimated values for this sample. This sample could not be reanalyzed after discovery of the error because the hold time for the analysis had expired. We have corrected the error with our software, and this type of error should not reoccur. If you need additional information regarding the data for these samples, please contact me at 704-875-9092 Ext. 229.
