THE DIRECTOR OR HIS DESIGNEE WILL PRESENT THIS TO THE COMMISSION. YOUR PRESENCE AT THIS MEETING WILL SERVE TO ASSIST IN ADDRESSING ANY QUESTIONS THE COMMISSION MEMBERS HAVE ON THIS VARIANCE. THE EMC MEETING IS AT 9:00 AM AND IS NORMALLY HELD IN THE ARCHDALE BUILDING GROUND FLOOR HEARING ROOM. I HAVE NOT YET SEEN AN AGENDA. IF WE NEED TO TALK GIVE ME A CALL AT (919) 715-6189. DH AGENDA ITEM: EXPLANATION: Hearin g Officer's Re port and Re quest for Variance for a Site Owned by the Goodwill Industries of the Southern Piedmont in Charlotte . North Carolina. Goodwill Industries of the Southern Piedmont is located inside the city limits of Charlotte at 2122 Freedom Drive, Goodwill Industries of the Southern Piedmont is a non-profit organization and serves as a vocational rehabilitation training center for the handicapped. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest comer of the building. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of this property. The area of the plume was estimated to be approximately 60,000 square feet. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. This corrective action plan was implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup system. Pump- and-treat technology uses a pump to convey contaminated groundwaters from beneath the land, treats these groundwaters to remove contaminants, and return the treated water to a permitted discharge. The Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte-Mecklenburg Utility Department issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. Beginning in May 1991 the Division of Water Quality required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site and to determine the effectiveness of groundwater cleanup. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Groundwater sampling has also been conducted at recovery wells used as sumps to collect groundwater, free product, and dissolved hydrocarbons. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat operations that was approved by the Division in October 1994. The temporary interruption of the cleanup system was done to determine if residual concentrations of substances in groundwater and the subsurface would increase significantly if no treatment system was in operation. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to ISA NCAC 2L .0113(b). An increase in the concentration of Naphthalene was reported from the April 17, 1996 semiannual monitoring event from Monitoring well# 5. This well is located within the area of the contaminate plume and is beneath 1 the building. No known sources of drinking water from water wells or surface water supplies are known to exist within a½ mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. The company believes that the variance will not impact surface waters in the area. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). On October 13, 1995 the Mooresville Regional Office recommended approval of this variance request be made on the condition that an additional monitoring well be installed and that semiannual monitoring be conducted at selected monitoring wells at the site. Pursuant to 15A NCAC 2L .0113( d) and ( e ), public notice of this variance was sent to adjacent property owners, the Mecklenburg County Health Director, the City Manager of Charlotte, and the Mayor of Charlotte. Notice of this hearing was also published in the February 15, 1996 edition of the Charlotte Observer to meet the requirements of 15A NCAC 2L ~0113(e)(l)(A). In addition, approximately 130 notices of this variance were sent to persons listed in the "Groundwater Variance and Regulatory Actions Mailing List" to meet the requirements of 15A NCAC 2L .0113(e)(l)(F). On March 19, 1996 a public hearing on this proposed variance was held pursuant to 15A NCAC 2L .0113 in Charlotte, North Carolina. The hearing was attended by three persons representing Goodwill Industries of the Southern Piedmont and their consulting firm S&ME Inc. No oral comments were expressed at the hearing and no written comments were received during the hearing. Only one written comment was received prior to the closing of the hearing record on April 19, 1996 from Mr. James Ponder, the project geologist with S&ME Inc. Mr. Ponder proposed a semi-annual monitoring schedule for one year followed by annual sampling thereafter. These recommendations were based upon discussions with Mooresville Regional Office staff. His comments also addressed specific analytical methods to be used and the infeasibility of installing an additional monitoring well. On.June 21, 1996, the North Carolina General Assembly enacted Senate Bill 1317 into law that allows clean-up activities to be temporarily suspended pending adoption of risk-based assessment and corrective action rules for certain sites where releases of petroleum from underground storage tanks have occurred. The legislation specifies that sites with a priority ranking of C, D, or E be classified as Class CDE must suspend cleanup activities including monitoring. Senate Bill 1317 also requires that responsible parties of these sites will not receive reimbursements for the state trust fund unless they can meet the hardship provisions of the law. In light of the fact that the Goodwill Industries site in the proposed variance falls under this classification, the Division informed the company that it will not require cleanup of the site at 2221 Freedom Drive at the present time. This notification was sent to Goodwill Industries through it's consultant on September 6, 1996. It was also requested that Goodwill Industries of Southern Piedmont inform the Groundwater Section of intention to continue pursuing a variance in light of this legislative change. On September 11, 1996 Goodwill Industries of the Southern Piedmont informed that Groundwater Section of its intention to continue pursuing a variance at this site. Based upon the legislation enacted in Senate Bill 1317, Goodwill Industries interest in a variance for this site, and site specific factors shown in the September 16, 1996 letter ( See Attachment # 5 of the Hearing Officer's Report), the Mooresville Regional Office revised previous recommendations for monitoring requirements. The Mooresville Regional Office recommends that no monitoring be required as a condition of granting the variance request. This recommendation is based on the amount of soil 2 .. and groundwater remediation conducted at the site, the fact that the plume of contamination does not appear to be migrating offsite, the low risk the site poses to drinking water supplies, and other factors shown in the September 16, 1996 letter It must be noted that a total of$371,896 has been expended to clean-up this site, approximately $294,774 incurred from the State Underground Storage Tank Trust Fund. This included contaminated soil removal to the extent practicable and groundwater extraction and treatment. Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that continued operation of best available technology will not result in significant long term remediation of the site to the groundwater quality standards in 1 SA NCAC 2L .0202 and contend that continued operation of the existing system will be a serious financial burden without equal or greater public benefit. Contaminated soil ( 1154 tons) has been excavated and disposed of appropriately. A groundwater pump and treat system was in operation for approximately 18 months and treated in excess of 2 million gallons of water. There has been no significant increase of contaminants since the system has been shut down. The contaminated groundwater plume is limited to the site near Monitoring Well# S and has not impacted off-site properties at this time. Groundwater modeling predicts that it would take 10 years for the contaminant plume to reach adjoining property assuming no attenuation or degradation of the contaminants. This variance request applies only to an area of property owned by Goodwill Industries of the Southern Piedmont. RECOMMENDATION: It is recommended that the Environmental Management Commission grant the variance request for Goodwill Industries of the Southern Piedmont ( Groundwater Incident Number # 8094) pursuant to the requirements of ISA NCAC 2L .0113 and North Carolina General Statute 143-215.J(e). It is also recommended that this variance request be approved without further monitoring requirements based upon the low site priority ranking of the site, the limited areal extent of contamination, the ability of the contaminants to attenuate, and the financial burden on Goodwill Industries of continued remediation without significant environmental improvement. 3 , '-\\!' ;~~, -.

I served as the hearing officer and a summary of the public hearing and my recommendations are attached for your consideration. The issue concerns whether the Environmental Management Commission (EMC) should approve or deny a request for a variance of the Groundwater Quality Standards inTitle 15A North Carolina Administrative Code (NCAC) Subchapter 2L .0202 (15A NCAC 2L .0202) and 15A NCAC 2L .01060). Such a variance may be granted by the EMC under the authority of North Carolina General Statute (NCGS) 143-215.3(e). The procedures for application and for public notification found in 15A NCAC 2L .0113 have been followed for this request . Also attached for your review and consideration are those documents considered relevant to this request including a summary of background information. If you have any questions, please do not hesitate to call . ., PUBLIC HEARING A public notice was published advising interested parties that a public hearing was scheduled on March 19, 1996 (Attachment 1). The public hearing was conducted as scheduled. The Division was represented by four staff members: Sherri Knight Allen Schiff Keith Overcash David Hance Hearing Officer Mooresville Regional Office Mooresville Regional Office .Recorder The hearing was attended by three citizens representing Goodwill Industries of the Southern Piedmont and their consulting firm S&ME (Attachmeni 2). No one present requested to make verbal comments. Opening remarks were given by the hearing officer, followed by the staff presentation by Allen Schiff (Attachment 3). No written comments were received during the hearing and only one was received prior to the closing of the hearing record on April 19, 1996 (Attachment 4). In general, the written comments, submitted by James Ponder, project geologist with S&ME, proposed a semi-annual monitoring schedule for one year followed by annual sampling thereafter. These recommendations were based upon discussions with Mooresville Regional Office staff. The comments also addressed specific analytical methods to be used and the infeasibility of installing an additional monitoring well. On June 21, 1996, the North Carolina General Assembly enacted Senate Bill 1317 into law that allows clean-up activities (including monitoring) to be temporarily suspended pending adoption of risk-based assessment and corrective action rules for certain sites where releases of petroleum from underground storage tanks have occurred. The legislation specifies that sites with a priority ranking of C,D, or Ebe classified as "Class COE". In light of the fact that the Goodwill Industries site in the proposed variance falls under this classification, the Division informed the company that it will not require cleanup of the site at 2221 Freedom Drive at the present time. This notification was sent to Goodwill Industries through it's consultant on September 6, 1996. It was also requested that Goodwill Industries of Southern Piedmont inform the ·Groundwater Section of intention to continue pursuing a variance in light of this legislative change.

The hearing concerns a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the. Cqrrective Action requirements of 15A NCAC 2L .0106 G) for Goodwill Industries of the Southern Piedmont, Inc. The variance application from Goodwill Industries was received for review by the Department on July 28, 1995. · The property where the release of petroleum-product has occurred is located as follows: Enter the City of Charlotte from Interstate 85 and take Freedom Drive (US 27) toward downtown. Go 3/4 of a mile. Goodwill Industries is located at the corner of Berryhill Road and Freedom Drive. The street address for this property is 2122 Freedom Drive. Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority of ISA NCAC 2L .0113 so that it does the following: I (1) Allow concentrations of Benzene, Toluene, Ethyl benzene, Xylene (-o,-m, and p ), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above 15A NCAC 2L .0202 standards as analvzed Anril 13 . 1 . These concentrations will e required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one- .. half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedinont is located within an area with a mixture of commercial, industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest corner of the building .. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a : Comprehensive Site· Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking' lot of this property. The area of the plume was estimated to be approximately 60,000 square feet. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992 which was approved and implemented on September 6, 1992." Goodwillindustries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup . system. The Corrective Action Plan was approved by the Division on October 22, 1992. Beginning in May 1991 the Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site and to determine the effectiveness of groundwater cleanup. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Groundwater sampling has also been conducted at recovery wells used as sumps to collect groundwater, free product, and dissolved hydrocarbons. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions iri the concentrations 1 2) _;_J . ' I ATTACHMENT #1 r ~fNaphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treac operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to ISA NCAC 2L .0113(b). No known sources of drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface · and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. The company believes that the variance will not impact surface waters in the area. ~ Allow for the restoration of groundwater without requiring remedial actions in accordance with :.:Y c-.. 15A NCAC 2L .0106G). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application of best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in ISA NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,18S gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. _ _J Goodwill Industries of the Southern Piedmont has considered the use of air sparging with yapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of ISA NCAC 2L .0113(c)(5). The total estimated cost of installing this technology plus one years maintenance is $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss of income. Goodwill Industries of the Southern· Piedmont has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the rema.hting contamination at this site. The company does not believe that this technology is the "best ·available technology economically reasonable" as specified in ISA NCAC 2L .0113(c)(S). Goodwill Industries asserts that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. · · 2 , .. r Attachment # 2 -PROCEEDING OF THE HEARING AND REGISTRATION LIST Attachment# 2 PROCEEDINGS OF HEARING FOR THE GOODWILL INDUSTRIES OF THE SOUTHERN PIEDMONT VARIANCE (GW INCIDENT # 8094) INTRODUCTION: A public hearing was held by the Department of Environment, Health and Natural Resources on behalf of the Environmental ~anagement Commission to receive public comment on a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the Corrective Action requirements of 15A NCAC 2L .0106 G) for Goodwill Industries of the Southern Piedmont in Charlotte, North Carolina for property it presently owns at 2122 Freedom Drive.

S&ME, Inc., on behalf of Goodwill Industries (Goodwill) Inc., submits this letter, proposing a groundwater quality monitoring plan to be considered with the proposed variance request for the above referenced site. S&ME proposes to collect groundwater samples from 7 _ wells (MW-1 through MW-7) and water levels in all wells semiannually for one year and annually thereafter. The semi-annual sampling events will be performed during April 1996 and September 1996 to potentially coincide with the seasonal high and low groundwater levels and the annual events will be scheduled during the seasonal high groundwater levels. Additionally, we suggest that the laboratory analyses be limited to those compounds that have consistently been detected in the monitoring wells, using EPA Methods 602 (BTEX) plus MTBE and 610 for naphthalene . .,.

On October 13, 1995, the MRO forwarded you a variance request· for the subject •site along with the · MRO' s recommendation that selected monitor we.11.s be sampled semi-annually if the variance was approved. ··upon further review of the variance reg14:est ~nd 15A NCAC 2L > 0113 the MRO feels-that the variance should be approved without any further monitoring for the/ following re_~sons : _ ' 1. The groundwater contaminant plume does not extend offsite. 2. The contaminant plume, for the most part, exists under the Goodwill building. 3. Goodwill has calculated that it would take ten years for any --contaminants to reac.h the adjoining downgradient property, .assuming no attenuat;•ion or degradation. 4. Goodwill has also calculated that it would take 63 years for · the contaminants to reach the nearest surface water body, assuming no attenuation or degradation. 5. ;Public water supply ·lines in the · area of the Goodwill 'facility are buried too shallow to be impacted by contaminants found at the site. 6. 1154 tons of contaminated soils have been excavated and disposed of at a permitted faqility. 7. ~ groundwater pump and treat system was in operation from November 1, 1993 until May 5, 1995. This system treated a total of 2,108,185 gallons of groundwater during its operation. No significant increase of contaminants has occurred since the system has been shut off. 170/z;o·d 8S:8 96, 81 das 8Jd fl19 W3a ~NH3a ATTACI-MENT #5 · 8.

Chief, Groundwater Section FROM: Carl Bailey (./:) Assistant Chief for Planning, Groundwater Section SUBJECT: Variance Request for the Goodwill Industries of the Southern Piedmont in Charlotte, North Carolina. The Groundwater Section is in the process of reviewing a request for variance from Title 15A North Carolina General Statutes, Subchapter 2L "Classi fi cations and Water Oualitv Standards Auv licable to the Groundwaters o f North Carolina" for the subject site. The petitioner, Goodwill Industries of the Southern Piedmont, requests a variance from 1 SA , NCAC 21 .0202 (Groundwater Quality Standards) and 15A NCAC 21 .01060) (Corrective Action Plans). ·· Attached for your consideration is a memorandum in which staff have provided comments concerning the information required to be submittedjn support of the request in accordance with 15A NCAC 2L. 0113(c) and which must be considered by the Environmental Management Commission (EMC) prior to granting a variance. Based on the info~ation received thus far, this facility seems to be a good candidate for a variance. Your concurrence is needed so that the Division can proceed with public notice of hearing in accordance with procedures set out in 15A NCAC 2L .0113(d) and (e) and for subsequent review by the Environmental Management Commission. 1 t . ,· ·, C I/ The Groundwater Section would like present this request as an information item to the Groundwater Committee at the February 8, 1996 meeting, if the Committee Chairman chooses to hold a meeting.

Implementation of the Corrective Action Plan was approved by the Division on October 22, 1992~ The Charlotte Mecklenburg Utility Department (CMUD) issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site. On September 21, 1994 the company conducted · comprehensive groundwater sampling at eight monitoring wells. The deepest of the monitoring wells is known as "DMW-3" and is 44 feet below the land surface. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. Only Benzene was found in the monitoring wells. The highest concentration found in a monitoring well in exceedence ofthe 15A NCAC 2L .0202 Groundwater Quality Standard for Benzene during this sampling event was 0.011 milligrams/Liter_ in Monitoring Well# 4. _ The Division also required Goodwill Industries to evaluate the effectiveness of groundwater cleanup efforts by examining concentrations of substances recovery wells used as sumps to collect free product and dissolved hydrocarbons from the site. Samples were obtained from six recovery wells located beneat4, the building, parking lot, and loading dock areas. Groundwater samples were · analyzed using US Environmental Protection Methods 602 and 625. The highest .. Benzene concentration in a recovery well showed 0.290 milligrams/Liter at Recovery Well# 5 beneath the building. Downgradient Monitoring Well# 7 .. located offsite southeast next to Freedom Drive did not show any concentrations above practical quantitation levels. Based on these results the Division of Environmental Management recommended the pump-and-treat system be turned off for a period of two months to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily tu,rned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzen~ in · all six recovery wells showed a significant decrease during this sampling event. Based on the results of the December 1994 monitoring, Goodwill Industries of the Southern Piedmont informed the Charlotte-Mecklenburg Utilities Department (CMUD) in January 1995 that it intended to request a variance at this site. In Appendix ID the January 12, 1995 memorandum from CMUD informed the responsible party that the existing permit to discharge treated . groundwater into the sewer system would be extended beyond August 31, 1995 for an additional year, if the variance to terminate remediation is not granted by the Commission during the time. As shown in Appendix m, CMUD stated that the permit would be "extended" not "re-issued". On July 28, 1995 Goodwill Industries sent a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b ). 3 c-- / l ·. ATTACI-L'-1ENT 6 did not reveal Dimethyl Phtha.Iate contamination in Recovery Well# 5, other recovery wells, or monitoring wells. In Table 2 of the report, the December 9, 1994 groundwater sampling was conducted at monitoring wells showed the concentrations of Benzene, Toluene, Ethylbenzene,_ Xylenes, and MTBE below their respective Groundwater Quality Standards in 15A NCAC 2L .0202. None of the monitoring wells showed concentrations of these substances above practical quantitation li:rp.its. The only wells that showed any concentration levels above Groundwater Quality Standards in 15A NCAC 2L .0202 from the USEP A Method 602 analysis were the recovery wells (RW #1 through RW # 6). The highest concentration in any single recovery well during this period was 0.071 inilligrams per Liter (mg/L) or 71 micrograms per Liter (ug/L) at RW # 5. The .analysis of samples using USEP A Method 625 did not reveal any concentrations of phthalate compounds, 1,2-Dichlorobenzene, or Naphthalene in the monitoring wells above the Groundwater Quality 'Standards in 15A NCAC 2L .0202. Base/Neutral extractable compounds, such as Anthracene, did not appear in concentrations above Groundwater Quality Standards or Interim Maximum Allowable Concentrations in any of these wells. Recovery Well# 5 showed Naphthalene at 0.062 mg/Lor 62 ug/L. The ~· Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). This recovery well is located in the center of the building which houses Goodwill Industries of the Southern Piedmont. It is important to note that this December .. 1994 sampling event had occurred some time afte~ the pump-and-treat system. had been temporarily turned off pursuant to the Division's instructions. No significant increase in concentrations of substances was observed as a result of the temporary cess·atiori. of pump-and-treat cleanup. On April 13, 1995 Goodwill Industries conducted a routine sampling of monitoring and recovery wells at the site. Table 2 shows results from USEP A Method 602 analysis. Three monitoring wells (MW # 3, DMW # 3, and MW # 4 had concentrations of Benzene above the Groundwater Quality Standard of 0.001 mg/L (1 ug/L). Mon.itoring Well # 4 had the highest concentration of Benzene at 0.004 mg/Lor 4 ug/L. Recovery Wells #1 through# 6 showed levels of Benzene above the Groundwater Quality Standard established by 15A NCAC 2L .0202. USEP A Method 625 analysis did . not reveal any chemicals in monitoring wells above practical quantitation limits. Table 2 shows that Naphthalene continues to be present in Recovery Well # S at a concentration above the standard in 15A NCAC 2L .0202. Naphthalene was found in this well at '0.029 ing/L or 29 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). No other recovery wells have shown any constituents in exceedence of the standards contained in 15A NCAC 2L .0202 as a result of analysis using USEP A Method 625. Goodwill Industries of the Southern Piedmont has attempted to define the vertical extent of groundwater contamination beneath the site. The deepest well (DMW # 3) is 44 feet below the ground surface. Groundwater sampling and analysis was conducted using USEP A Method 602 and Method 625 at three 7 _;,----.... ; ·: ·:.~ ,.:·.--.;. ~-.-:_:.=-:_: ATTACl-fv1ENT 6 ! separate times in 1994 as shown in Table # 2. The analysis of the September 21, 1994 sampling event for DMW #3 showed a concentration of Benzene at 0.003 milligrams per liter. This level is in exceedence of the Groundwater Quality Standard of 0.001 milligrams per liter for this substance in ISA NCAC 2L .0202. The analysis of all other samples taken from this well in 1994 did not reveal any other chemical constituent from the p·etroleum release. A semi-annual sample was taken on April 13, 1995 at the monitoring well DMW # 3 and showed a Benzene concentration at 0.002 mg/Lor 2 ug/L. No other substances normally associated with a release of diesel fuel were found in this monitoring well during the April 1995 sampling. (see Table 2 of the report). _ Page 8 of the report states that the downgradient recovery well (RW # 6) has not shown " •.. any EPA Method 625 compounds and only 28 ug/1 of benzene ... ". Analysis of samples from the downgradient monitoring well MW # 7 has not , shown any substances as a result of using USEP A Method 602 or Method 625. Based on the groundwater flow velocity of 11 feet per year from the site assessment, the company ·estimates that the time it will take the petrochemical plume to reach monitoring well # 7 is 4.5 years. Goodwill Industries believes that it will take a ·total of 10 years for the substances to reach the downgradient :· property boundary. These estimates are based on conservative assumptions that the plume will not be impacted by natural remedial processes and attenuation effects within the subsurface. It is not anticipated that rainfall events will significantly impact the movement of contaminants offsite. The area where groundwater monitoring results showed concentrations of Benzene, Naphthalene, and Dimethyl Phthalate above the standards is beneath the building that houses Goodwill Industries of the Southern Piedmont.· The area outside this structure is covered by an asphalt driveway and parking area. No sources of drinking water from water wells or surface water are known to exist within a 1/2 mile radius of the Goodwill Industries of the Southern Piedmont. The requirements for variance ~pplications in 15A NCAC 2L .0113(c)(4) specify that locations of drinking water wells and other water supply sources that are within one-half mile of the site must be shown on a map. The report from Goodwill Industries states that there are no drinking water wells within one-half mile of the site for which the variance has been requested. The December 7, 1995 memorandum referencing "Private Drinking Water Information" shows that there are no drinking water supply intakes at surface water bodies located within a lf2 mile radius of the site. Drinking water for the City of Charlotte is obtained from Mountain Island Lake on the Catawba River five miles north-northwest of the site. All downgradient properties are supplied drinking water from the City of Charlotte. There are approximately six groundwater monitoring wells near the railroad tracks and Flemming 8 ' . ATTACI-MENT 6 remediating groundwater contamination. Some of the plumbing for the pump- and-treat cleanup system is located in various parts of the building. Continual reliance on the pump-and-treat system will mean that Goodwill Industries will not be able to utilize this additional space for offices. Based on the previous installation of the pump-and-treat groundwater remediation system, Goodwill Indusmes foresees the use of an air sparging system with vapor recovery to cleanup the site resulting in a major disruption of ' business operations at Goodwill Industries. The floor ~pace within the Goodwill Industries site would need major renovations in order to install this type of system. The loading dock area would need to be closed during construction and installation of the system causing the loss of unrecoverable revenues to the company. Continued operation of the pump-and-treat system may require additional expenses on the part of Goodwill Industries. On January 12, 1995 the Charlotte- ' Mecklenburg Utility Department (CMUD) gave Goodwill Industries an "extension" to continue discharging treated effluent from the pump-and-treat groundwater remediation system into the city's sewer system until August 31, 1996. No indication was given by CMUD as to future extensions or reissuan~ of a permit for the discharge beyond one year. If Goodwill Industries continues ·to conduct corrective action that necessitates the discharge of treated effluent and .. the CMUD does not continue permitting the discharge into the sewer system, the .. company will need to pursue a separate discharge for this system. Such a discharge may require the construction of piping and pumping devices to the nearest discharge point at a surface water body. The company reports that the nearest drainage feature is Stewart Creek located approximately 700 feet downgradient from the site. In addition, this discharge would need to meet the requirements of state NPDES water quality rules in 15A NCAC 2B. Permitting and construction of a new discharge line for tlie present pump-and-treat system would require the additional expense of funds by the responsible party. Assuming that the option of a discharge to Stewart Creek is the most cost effective of other alternatives and the site remains eligible for state trust fund reimbursement, the responsible party may receive reimbursement through the trust fund for "reasonable and necessary costs" during permitting and construction of the discharge line. The company believes that there is immense uncertainty that best available technology will remediate the groundwaters at this site to standards within a foreseeable period of time. Goodwill Industries of the Southern Piedmont asserts that allowing natural remedial processes to degrade and attenuate substances found at the site will be no less effective a method than using technologic methods discussed and will not entail the same burdensome costs upon the company. 12 t ~-- 1--·. ··~-.: ATTACI-MENT6 Goodwill Industries of the Southern Piedmont. Upon your concurrence with our recommendation, the Groundwater Section will pro·ceed with the preparation of the required public notice and hearing. Upon completing of the requirements of 15A NCAC 2L .0113(d - f), with a recommendation to grant this variance from the Environmental Management Commission Groundwater Committee, this request will proceed to the Environmental Management Commission for final action in ISA NCAC 2L .0113(g).

Sherri Knight, Groundwater Supervisor Winston-Salem Regional Office Hearing Officer's Report and Recommendations Variance Request from 15A NCAC 2L .0202 and .0106(j) Goodwill Industries of the Southern Piedmont 2122 Freedom Drive Charlotte, Mecklenburg County Groundwater Incident# 8094 Site Priority Ranking 'E' of Category 'CDE' In accordance with your memorandum dated March 14, 1996, a Public Hearing was held on March 19, 1996 at 7:00 p.m. in the Criminal Courts Building of the Mecklenburg County Courthouse in Charlotte, North Carolina. I served as the hearing officer and a summary of the public hearing and my recommendations are attached for your consideration. The issue concerns whether the Environmental Management Commission (EMC) should approve or deny a request for a variance of the Groundwater Quality Standards in Title 15A North Carolina Administrative Code (NCAC) Subchapter 2L .0202 (15A NCAC 2L .0202) and 15A NCAC 2L .0106(j). Such a variance may be granted by the EMC under the authority of North Carolina General Statute (NCGS) 143-215.3(e). The procedures for application and for public notification found in 15A NCAC 2L .0113 have been followed for this request. Also attached for your review and consideration are those documents considered relevant to this request including a summary of background information. If you have any questions, please do not hesitate to call. ., ' ' , PUBLIC HEARING A public notice was published advising interested parties that a public hearing was scheduled on March 19, 1996 (Attachment 1). The public hearing was conducted as scheduled. The Division was represented by four staff members: Sherri Knight Allen Schiff Keith Overcash David Hance Hearing Officer Mooresville Regional Office Mooresville Regional Office Recorder The hearing was attended by three citizens representing Goodwill Industries of the Southern Piedmont and their consulting firm S&ME (Attachment 2). No one present requested to make verbal comments. Opening remarks were given by the hearing officer, followed by the staff presentation by Allen Schiff (Attachment 3). No written comments were received during the hearing and only one was received prior to the closing of the hearing record on April 19, 1996 (Attachment 4). In general, the written comments, submitted by James Ponder, project geologist with S&ME, proposed a semi-annual monitoring schedule for one year followed by annual sampling thereafter. These recommendations were based upon discussions with Mooresville Regional Office staff. The comments also addressed specific analytical methods to be used and the infeasibility of installing an additional monitoring well. On June 21, 1996, the North Carolina General Assembly enacted Senate Bill 1317 into law that allows clean-up activities (including monitoring) to be temporarily suspended pending adoption of risk-based assessment and corrective action rules for certain sites where releases of petroleum from underground storage tanks have occurred. The legislation specifies that sites with a priority ranking of C,D, or E be classified as "Class CDE". In light of the fact that the Goodwill Industries site in the proposed variance falls under this classification, the Division informed the company that it will not require cleanup of the site at 2221 Freedom Drive at the present time. This notification was sent to Goodwill Industries through it's consultant on September 6, 1996. It was also requested that Goodwill Industries of Southern Piedmont inform the Groundwater Section of intention to continue pursuing a variance in light of this legislative change. On September 11, 1996 Goodwill Industries of the Southern Piedmont informed that Groundwater Section that it intends to continue pursuing a variance at this site. Based upon the legislation enacted in Senate Bill 1317, Goodwill Industries interest in a variance for this site, and site specific factors shown in the September 16, 1996 letter (Attachment # 5), the Mooresville Regional Office revised previous recommendations for monitoring requirements. The Mooresville Regional Office recommends that no monitoring be required as a condition of granting the variance request. This recommendation is based on the amount of soil and groundwater remediation conducted at the site, the fact that the plume of contamination does Attachment # 1 -PUBLIC NOTICE , 1 ATTACHMENT #1 1 NOTICE OF VARIANCE APPLICATION AND HEARING DEPART11ENT OF ENVIRON11ENT, HEALTH AND NATURAL RESOURCES DIVISION OF ENVIRONMENTAL MANAGEMENT Notice is hereby given of a variance application and public hearing to be held by the Department of Environment, Health and Natural Resources on behalf of the Environmental Management Commission. The hearing concerns a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the. Corrective Action requirements of 15A NCAC 2L .0106 G) for Goodwill Industries of the Southern Piedmont, Inc. The variance application from Goodwill Industries was received for review by the Department on July 28, 1995. The property where the release of petroleum product has occurred is located as follows: Enter the City of Charlotte from Interstate 85 and take Freedom Drive (US 27) toward downtown. Go 3/4 of a mile. Goodwill Industries is located at the comer of Berryhill Road and Freedom Drive. The street address for this property is 2122 Freedom Drive. Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority ?f ISA NCAC 2L .0113 so that it does the following: (1) Allow concentrations of Benzene, Toluene, Ethylbenzene, Xylene (-o,-m, and p ), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above ISA NCAC 2L .0202 standards as anal ze ril 13. 1 . These concentrations will e required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one- half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, i.ndustrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest comer of the building. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of this property. The area of the plume was estimated to be approximately 60,000 square feet. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992 which was approved and implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup system. The Corrective Action Plan was approved by the Division on October 22, 1992. Beginning in May 1991 the Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site and to determine the effectiveness of groundwater cleanup. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Groundwater sampling has also been conducted at recovery wells used as sumps to collect groundwater, free product, and dissolved hydrocarbons. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions in the concentrations 1 .. ' I I ATTACHMENT #1 of Naphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .Ol 13(b). No known sources of drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. The company believes that the variance will not impact surface waters in the area. 2) Allow for the restoration of groundwater without requiring remedial actions in accordance with 15A NCAC 2L .01060). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application of best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with yapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of ISA NCAC 2L .0113(c)(5). The total estimated cost of installing this technology plus one years maintenance is $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss of income. Goodwill Industries of the Southern Piedmont has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remairµng contamination at this site. The company does not believe that this technology is the "best available technology economically reasonable" as specified in 15A NCAC 2L .0113(c)(5). Goodwill Industries asserts that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. 2 . . 1 .,.

The groundwater contaminant plume does not extend offsite. 2. The contaminant plume, for the most part, exists under the Goodwill building. 3. Goodwill has calculated that it would take ten years for any -contaminants to reac.h the adjoining downgradient property, .assuming no attenuat;•ion or degradation. 4. Goodwill has also calculated that it would take 63 years for · the contaminants to reach the nearest surface water body, assuming no attenuation or degradation. 5. ;Public water supply lines in the · area of the Goodwill 'facility are buried too shallow ta be impacted by contaminants found at the site. 6, 1154 tons of contaminated soils have been excavated and disposed of at a permitted faqility. 7. A groundwater pump and treat system was in operation from November 1, 1993 until May 5, 199S. This system treated a total of 2,108,185 gallons of groundwater during its operation. No significant increase of contaminants has occurred since the system has been shut off. tl0lc0·d 96, 81 das 8Jd ~9 W3G ~H3G f . I I I ATTACl-fvlENT #5 . . , ... a.

' ATTACl-f,1ENT 6 DMSION OF ENVIRONMENTAL MANAGEMENT GROUNDWATER SECTION January .12, 1996 MEMORANDUM To: From: Subject: Preston Howard Arthur Mouberry (¥ Request for Variance from 15A NCAC 2L .0202 and 15A NCAC 2L .01060) for a Site Owned by Goodwill Industries of the Southern Piedmont at 2122 Freedom Drive in Charlotte, North Carolina (Mecklenburg County) {Groundwater Incident Number 8094}. Goodwill Industries of the Southern Piedmont is a non-profit organization and serves as a vocational rehabilitation training center for the handicapped. A 2,000 gallon underground storage tank containing diesel fuel was removed from the site on November 21, 1990. Pursuant to title 15A NCAC 2L .0113(c) variance applications are required to contain specific information in order to adequately review a request. Goodwill Industries variance application is contained in a report titled "Variance Re quest Incident Number 8094 Goodwill Industries of the Southern Piedmont. Inc. 2122 Freedom Drive Charl6tte , North Carolina S&ME Pro ject No. 1354-93-410". In addition, the Groundwater Section requested Goodwill Industries provide clarifying information and editorial corrections to some of the information submitted in the report. The corrected information is shown in memoranda submitted on November 27th, December 4th, and December 7th of 1995. The information submitted by S&ME Incorporated on behalf of Goodwill Industries of the Southern Piedmont appears to meet the requirements of 15A NCAC 2L .0l 13(c) and is summarized as follows: Rule .0l 13 (c)(l): Resolution by the Countv or governing Board: Goodwill Industries of the Southern Piedmont has always been a private non-profit organization. No resolution is necessary. 1 ' ' ATTACI-MENT 6 Rule .0113 (c)(2): A description of past existin g or pro posed activities that would result in a discharge of contaminants into gr oundwater: Goodwill Industries of the Southern Piedmont is located inside the city limits of Charlotte, North Carolina at 2122 Freedom Drive (Parcel Number 071- 063-13). The report titled "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Proiect No. 1354-93-410 contains the relevant information about this site. This facility is at the corner of Freedom Drive and · Berry Hill Road as shown in Figure 1 of Appendix in the report from S&ME Incorporated. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. The former owner of this location was A.G. Boone Trucking Company. A 2,000 gallon underground storage tank containing diesel fuel was at the northwest corner of the building. This underground storage tank was ~· removed on November 21, 1990 and the release was subsequently discovered ·upon tank closure. Goodwill Industries does not have any other underground storage tanks on this property. No other existing or potential sources of groundwater contamination were identified at this property by Goodwill Industries. Goodwill Industries of the Southern Piedmont and all adjacent properties are in an area with a mixture of commercial, industrial, and residential development. The tank closure report documented the removal of 240 tons of soil contaminated with diesel fuel. Analytical tests of soils within the excavation area did not indicate contamination below 21 feet from the ground surface. In August 1991 a Comprehensive Site Assessment was completed. The site assessment revealed a groundwater plume from a small area of contamination adjacent to the building. This area of contamination was at the northwest corner of Goodwill Industries near the companies loading dock and adjacent to the area where the diesel fuel pump had been located. The area of the plume was estimated to be approximately 60,000 square feet ( 400 feet long by 150 feet long). Monitoring indicated that the vertical extent of this plume was approximately 44 feet below the ground surface. The company estimated that approximately 5,924,952 gallons of groundwater had been contaminated by the release. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. From September 6, 1992 through November 9, 1992 approximately 914 tons of soil was excavated and treated offsite adjacent to the loading dock area. The treatment method used for this soil was thermal incineration. A Corrective Action Plan or "Remedial Action Plan" was submitted to the Division on July 2, 1992 to cleanup groundwater 2 .. ,.., . ATTACI-MENT 6 using pump-and-treat technology. Implementation of the Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte Mecklenburg Utility Department (CMUD) issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site. On September 21, 1994 the company conducted comprehensive groundwater sampling at eight monitoring wells. The deepest of the monitoring wells is known as "DMW-3" and is 44 feet below the land surface. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. Only Benzene was found in the monitoring wells. The highest concentration found in a monitoring well in exceedence of the 15A NCAC 2L .0202 Groundwater Quality Standard for Benzene during this sampling event was 0.011 milligrams/Liter in Monitoring Well# 4. The Division also required Goodwill Industries to evaluate the effectiveness of groundwater cleanup efforts by examining concentrations of substances recovery wells used as sumps to collect free product and dissolved hydrocarbons from the site. Samples were obtained from six recovery wells located beneatl} the building, parking lot, and loading dock areas. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. The highest . Benzene concentration in a recovery well showed 0.290 milligrams/Liter at Recovery Well # 5 beneath the building. Downgradient Monitoring Well # 7 . located offsite southeast next to Freedom Drive did not show any concentrations above practical quantitation levels. Based on these results the Division of Environmental Management recommended the pump-and-treat system be turned off for a period of two months to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily turned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzene in all six recovery wells showed a significant decrease during this sampling event. Based on the results of the December 1994 monitoring, Goodwill Industries of the Southern Piedmont informed the Charlotte-Mecklenburg Utilities Department (CMUD) in January 1995 that it intended to request a variance at this site. In Appendix m the January 12, 1995 memorandum from CMUD informed the responsible party that the existing permit to discharge treated groundwater into the sewer system would be extended beyond August 31, 1995 for an additional year, if the variance to terminate remediation is not granted by the Commission during the time. As shown in Appendix m, CMUD stated that the permit would be "extended" not "re-issued". On July 28, 1995 Goodwill Industries sent a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). 3 ATTACl-ftlENT 6 Potential sources of groundwater contamination in the area are shown in Figure 2 in the report "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" and include the following: 1) A retail gasoline station· presently owned by Servco located approximately 800 feet northwest of Goodwill Industries on Freedom Drive; 2) A fuel oil tank located approximately 250 feet to the northeast from Goodwill Industries. This fuel oil tank appears to be on property owned by Flemming Laboratories Incorporated; 3) An H 2S04 tank located approximately 250 feet to the northeast from Goodwill Industries. This chemical tank appears to be on property owned by Flemming Laboratories Incorporated; ; 4) An area containing what is described as "hazardous waste drul!ls" approximately 250 to 300 feet to the east from Goodwill Industries. Figure # 2 appears to show that these drums are on property owne~ by Flemming Laboratories Incorporated. 5) 6) 7) 8) 9) 10) Monitoring Wells owned by Flemming Laboratories Incorporated. These wells are located to the east and northeast of the Goodwill Industries site. Berry Hill Road (a public roadway); Freedom Drive (a public roadway); A CSX Transportation Incorporated railroad line that is to the northeast and east of Goodwill Industries. The former owner of this line was the Piedmont and Northern Railroad Company; A sewer line that is within of few feet of the southwest property line of Goodwill industries. This sewer runs from northwest to southeast parallel to the Goodwill Industries property line; A storm drain line that is within of few feet of the southwest property line of Goodwill industries. This storm drain runs from northwest to southeast parallel to the Goodwill Industries property line; and 4 • 1 1 •• , • ATTACI-MENT 6 11) Numerous other storm drain lines and sewer lines that are in the general area. The property for which the variance is requested is entirely owned by Goodwill Industries of the Southern Piedmont. The groundwater that was impacted by the release is located beneath the building and the parking lot area. A fence is located at the northeast side of the building. Access to impacted groundwater at the site by workers, visitors, and unlawful intruders is under the control of the responsible party. Rule .0113(c)(3): Description of the proposed area for which the variance is requested: This variance is for an area entirely within the property boundaries of the Goodwill Industries of the Southern Piedmont. Maps of this area are shown in Figure 3 and Appendix Il of the report titled "Variance Reguest Incident _. Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Project No. 1354-93-410". The contaminated area is in the form of an ellipse with it's longitudinal axis from northwest to southeast. The southeastern side of this ellipse is within a few f ~et of the storm drain line and sewer line that runs alongside Freedom Drive. More specifically the area for which the variance is requested is bounded to the north by the property line with Suburban Propane Company. This area laterally extends to the northeast toward the Suburban Propane Company property line, running beneath the Goodwill Industries Building, but does not extend as far as Monitoring Well # 6. The lateral area extends southeast toward property owned by D.L. Appliance Company but not as far as Monitoring Well# 7. The southwestern boundary of this area is at the property line that runs parallel with Freedom Drive. The western extent of this area is beneath the building and does not go as far as the position of Monitoring Well # 1. The extent of the northwest boundary includes part of the asphalt parking lot but does not go beyond the site where the diesel underground storage tank pump island once existed. The lateral extent of this plume stops before it reaches Monitoring Well# 2. The concentration of contaminants in groundwater is primarily influenced by the direction and rate of groundwater flow. Goodwill Industries asserts that groundwater flow from the site travels toward a tributary of Stewart Creek approximately 700 feet to the southeast. This creek discharges into the Catawba River. The groundwater flow rate was obtained from information in the Comprehensive Site Assessment (CSA). Based on information in the CSA, Goodwill Industries of the Southern Piedmont asserts that groundwater in the area flows in a southeast direction. The 1994 groundwater monitoring results 5 ATTACf-b'lENT 6 from recovery wells beneath the building indicated that the contaminant plume is moving in a southeasterly direction toward Freedom Drive. The estimated groundwater flow velocity in the subsurface is approximately 11 feet/year. The company asserts that at this rate of groundwater movement the plume of petroleum hydrocarbon contamination will enter Stewart Creek in approximately 63 years, assuming no natural degradation or attenuation of the plume occurs (See page 9 of the report). Page 3 of the report states that the company does not believe that any natural geologic structures exist in the subsurface beneath the site that would have_ the effect of creating an impermeable boundary to groundwater movement. Goodwill Industries believes that the depth to bedrock beneath the site is between 50 and 100 feet. No other properties owned by Goodwill Industries of the Southern Piedmont or properties owned by other persons are being included in this application for variance. (refer to Appendix II of the report). Rule .0113(c)(4): Supporting information to establish that the variance will not endanger the public health and safety ... : The part of the variance concerning Groundwater Quality Standards shown in 15A NCAC 2L. 0202 has been requested for Benzene, Ethylbenzene, Toluene, Xylene(-o,-m, and p), Naphthalene, Methyl Tert-Butyl Ether (MTBE;), Dimethyl Phthalate, and 1,2-Dichlorobenzene. In order to assess health impacts from this site, monitoring wells were sampled at this site to assess the extent of contamination and concentration levels of substances. Concentrations of substances in recovery wells were also examine to determine the effectiveness of the pump and treat system at removing these chemicals. Groundwater monitoring data from Goodwill Industries of the Southern Piedmont indicates that this site does not pose a hazard to the public. Sampling and analysis has been conducted since May 8, 1991 at monitoring wells and recovery wells. Three sampling events occurred in March, September, December of 1994 and the last sampling and analysis was done on April 13, 1995. USEP A Method 602 and Method 625 were the analytical methods used for samples collected at the Goodwill Industries site. USEP A Method 602 is used to assess the concentration levels of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE. USEP A Method 625 is used to examine the concentrations of phthalate compounds, 1,2-Dichlorobenzene, Base/Neutral Extractables, and Naphthalene. The highest concentration of any substance found at this site was 0.590 milligrams per liter (mg/L) or 590 micrograms per liter (ug/L) of Dimethyl Phthalate in Recovery Well# 5. The Groundwater Quality Standard for this substance is zero pursuant to 15A NCAC 2L .0202(c). The lateral extent of this reported contamination is shown in Figure 4 of Appendix II. Dimethyl Phthalate was not detected in any other recovery wells or in monitoring wells during this sampling event. Analysis of subsequent groundwater samples in 1994 and 1995 6 ' . .. ATTACHMENT 6 did not reveal_ Dimethyl Phthalate contamination in Recovery Well# 5, other recovery wells, or monitoring wells. In Table 2 of the report, the December 9, 1994 groundwater sampling was conducted at monitoring wells showed the concentrations of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE below their respective Groundwater Quality Standards in 15A NCAC 2L .0202. None of the monitoring wells showed concentrations of these substances above practical quantitation limits. The only wells that showed any concentration levels above Groundwater Quality Standards in 15A NCAC 2L .0202 from the USEP A Method 602 analysis were the recovery wells (RW #1 through RW # 6). The highest concentration in any single recovery well during this period was 0.071 milligrams per Liter (mg/L) or 71 micrograms per Liter (ug/L) at RW # 5. The analysis of samples using USEP A Method 625 did not reveal any concentrations of phthalate compounds, 1,2-Dichlorobenzene, or Naphthalene in the monitoring wells above the Groundwater Quality Standards in 15A NCAC 2L .0202. Base/Neutral extractable compounds, such as Anthracene, did not appear in concentrations above Groundwater Quality Standards or Interim Maximum Allowable Concentrations in any of these wells. Recovery Well# 5 showed Naphthalene at 0.062 mg/Lor 62 ug/L. The ;• Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). This recovery well is located in the center of the building which houses Goodwill Industries of the Southern Piedmont. It is important to note that this December 1994 sampling event had occurred some time after the pump-and-treat system had been temporarily turned off pursuant to the Division's instructions. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat cleanup. On April 13, 1995 Goodwill Industries conducted a routine sampling of monitoring and recovery wells at the site. Table 2 shows results from USEP A Method 602 analysis. Three monitoring wells (MW # 3, DMW # 3, and MW # 4 had concentrations of Benzene above the Groundwater Quality Standard of 0.001 mg/L (1 ug/L). Monitoring Well# 4 had the highest concentration of Benzene at 0.004 mg/Lor 4 ug/L. Recovery Wells #1 through# 6 showed levels of Benzene above the Groundwater Quality Standard established by 15A NCAC 2L .0202. USEP A Method 625 analysis did not reveal any chemicals in monitoring wells above practical quantitation limits. Table 2 shows that Naphthalene continues to be present in Recovery Well# 5 at a concentration above the standard in 15A NCAC 2L .0202. Naphthalene was found in this well at 0.029 mg/L or 29 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). No other recovery wells have shown any constituents in exceedence of the standards contained in 15A NCAC 2L .0202 as a result of analysis using USEPA Method 625. Goodwill Industries of the Southern Piedmont has attempted to define the vertical extent of groundwater contamination beneath the site. The deepest well (DMW # 3) is 44 feet below the ground surface. Groundwater sampling and analysis was conducted using USEP A Method 602 and Method 625 at three 7 ' ,_ ... ATTACI-MENT 6 ., separate times in 1994 as shown in Table # 2. The analysis of the September 21, 1994 sampling event for DMW #3 showed a concentration of Benzene at 0.003 milligrams per liter. This level is in exceedence of the Groundwater Quality Standard of 0.001 milligrams per liter for this substance in 15A NCAC 2L .0202. The analysis of all other samples taken from this well in 1994 did not reveal any other chemical constituent from the petroleum release. A semi-annual sample was taken on April 13, 1995 at the monitoring well DMW # 3 and showed a Benzene concentration at 0.002 mg/L or 2 ug/L. No other substances normally associated with a release of diesel fuel were found in this monitoring well during the April 1995 sampling. (see Table 2 of the report). Page 8 of the report states that the downgradient recovery well (RW # 6) has not shown " ... any EPA Method 625 compounds and only 28 ug/1 of benzene ... ". Analysis of samples from the downgradient monitoring well MW # 7 has not shown any substances as a result of using USEP A Method 602 or Method 625. Based on the groundwater flow velocity of 11 feet per year from the site assessment, the company estimates that the time it will take the petrochemical plume to reach monitoring well # 7 is 4.5 years. Goodwill Industries believes . that it will take a 'total of 10 years for the substances to reach the downgradient ;• property boundary. These estimates are based on conservative assumptions that the plume will not be impacted by natural remedial processes and attenuation effects within the subsurface. It is not anticipated that rainfall events will significantly impact the movement of contaminants offsite. The area where groundwater monitoring results showed concentrations of Benzene, Naphthalene, and Dimethyl Phthalate above the standards is beneath the building that houses Goodwill Industries of the Southern Piedmont. The area outside this structure is covered by an asphalt driveway and parking area. No sources of drinking water from water wells or surface water are known to exist within a 1/2 mile radius of the Goodwill Industries of the Southern Piedmont. The requirements for variance applications in 15A NCAC 2L .0113(c)(4) specify that locations of drinking water wells and other water supply sources that are within one-half mile of the site must be shown on a map. The report from Goodwill Industries states that there are no drinking water wells within one-half mile of the site for which the variance has been requested. The December 7, 1995 memorandum referencing "Private Drinking Water Information" shows that there are no drinking water supply intakes at surface water bodies located within a 1/2 mile radius of the site. Drinking water for the City of Charlotte is obtained from Mountain Island Lake on the Catawba River five miles north-northwest of the site. All downgradient properties are supplied drinking water from the City of Charlotte. There are approximately six groundwater monitoring wells near the railroad tracks and Flemming 8 • \1 • • • • •' . ATTACI--MENT 6 Laboratories Incorporated. These are to the northeast of the Goodwill Industries and are cross-gradient from the site. It appears unlikely that the presence of these wells would result in the movement of petroleum contamination from Goodwill Industries into groundwater. It is highly improbable that public water supply lines will be impacted by this variance. The nearest water supply lines are a 20 inch line that runs parallel on Freedom Drive and an eight inch ~upply line that runs along Berry Hill Road. The Groundwater Section contacted the Administration Division at the Charlotte- Mecklenburg Utility Department (704-399-2551) and was informed that the average ·depth of these water lines from the ground surface is four feet. Groundwater contamination beneath Goodwill Industries is too deep within the subsurface to impact these lines. Rule .Ol 13 (c)(5): Supporting information to establish that re quirements of the rule cannot be achieved b y providin g best available technolo gy economically reasonable: The part of the request that concerns variance to Corrective Action in_.15A NCAC 2L .0106(j) will allow Goodwill Industries of the Southern Piedmont fo discontinue Corrective Action at this site. Goodwill Industries of the Southern Piedmont has submitted supporting information in the report and other documents demonstrating that the continued application of BAT will not res~lt in significant long term remediation of the site to the Groundwater Quality Standards, contained in 15A NCAC 2L .0202. The is due to the high probability that continued remediation activities at the site will not significantly reduce contaminant levels below Groundwater Quality Standards in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated approximately 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Page 11 of the report titled "Variance Re q uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" states that a total of $371,896 has been expended to cleanup this site. Goodwill Industries of the Southern Piedmont has incurred $77,122 of this total in the form of State Trust Fund deductibles and non-reimbursed items. Concentrations of substances in the groundwater have not been significantly reduced over the last year as shown in Table 2 of the report. Monitoring wells have shown insignificant reductions in Benzene using pump-and treat technology. Significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. It is also important to note that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted groundwater monitoring data indicated no increase 9 . . ATTACHMENT 6 in the concentration of any constituent. In order to demonstrate that the requirements of the rule cannot be achieved using best available technology, Title 15A NCAC 2L .0113(c)(5) requires that specific technology considered be identified, the costs of implementing the technology be shown, and the impacts of the costs on the applicant be provided. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is practical to meet the requirements of 15A NCAC 2L .0113(c)(5). In order to meet EHNR air quality standards, an air sparging system would need to be used in conjunction with vapor extraction to prevent fugitive vapors from spreading into the environment. The company asserts that two air sparging wells would need to be located inside the building in order to have an effective · remediation system. The use of vapor extraction at the Goodwill Industries site would necessitate additional measures to protect workers from harmful concentrations of substances inside the building. The costs required to continually control vapor flow within the plant and the potential risk to workers offsets any inherent benefits of this cleanup method. Pursuant to the requirements of 15A NCAG 2L .0113(c)(5), the company does not believe that air sparging with vapor extraction an "economically reasonable" technology for this site. The Goodwill Industries of the Southern Piedmont has furnished cost information for an air sparging system with vapor extraction in Table 3 of th_e report "Variance Request Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Project No. 1354-93-410". This information is summarized as follows: ·Technology Air Sparging System Soil Vapor Extraction System Piping & Underground Utilities Permitting, Project Management, On-Site Supervision Plus Operation and Maintenance for One-Year ' Total Cost ($) $21,000 $17,600 $23,000 $38,400 Estimated Total Cost = $100,000 10 ,_.,.- i .1 ATTACf-MENT 6 Goodwill Industries has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. Enhanced in-situ bioremediation involves the introduction of nutrients and oxygen into groundwater. The company does not believe that this technology is the "best available technology economically reasonable" as specified in ISA NCAC 2L .0113(c)(S). If enhanced in-situ bioremediation was selected as the cleanup method for the Goodwill Industries site it would involve the use of injection wells to introduce nutrient substances into the subsurface that would assist in biodegradation. In order to permit injection wells under the current rules in ISA NCAC 2C .0200 they would have to permitted as Type SX (Other Wells). On page 2 of a December 4, 1995 memorandum the company's environmental consultant stated that permitting of injection wells for enhanced in-situ bioremediation would require the company to conduct extensive groundwater modeling studies and geochemical modeling. In addition, a site specific design for the injection well field would need to be developed prior to obtaining a permit. In addition, a corrective action plan using in-situ bioremediation woul~ also need to be reviewed under the criteria in ISA NCAC 2L .0106(1). This rule requires a demonstration be made to the Director of the Division of Environmental Management that the site meets the criteria of ISA NCAC 2L .0106(1) so that the health, safety, and welfare of the public would not be impacted by allowing natural remedial processes to -cleanup the site. In a November 27, 1995 letter Goodwill Industries states that the investigative work required to submit this corrective action plan would involve lengthy studies of the geochemical properties of the site, flow properties of the contaminated matrix, and developing methods of measuring the contaminate concentration. A study of the feasibility of bioremediation would also need to be conducted to show that a corrective action plan under ISA NCAC 2L .0106(1) would effectively reduce contaminate concentrations to the level of the standards. The company believes that in order to determine the feasibility of in-situ enhanced bioremediation, an assessment of biologic processes in the soil would need to be examined and the toxicity of soils and sediments to these organisms would need to be assessed. Goodwill Industries believes that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. Rule .0113 (c)(6): Supp orting information to establish that compliance would produce serious financial hardshi p on the app licant: In pages 10 through 12 of the report reveals that Goodwill Industries of the Southern Piedmont has demonstrated that continued application of best available technology to this site would be a prohibitively expensive method of 11 ATTACf-MENT 6 remediating groundwater contamination. Some of the plumbing for the pump- and-treat cleanup system is located in various parts of the building. Continual reliance on the pump-and-treat system will mean that Goodwill Industries will not be able to utilize this additional space for offices. Based on the previous installation of the pump-and-treat groundwater remediation system, Goodwill Industries foresees the use of an air sparging system with vapor recovery to cleanup the site resulting in a major disruption of business operations at Goodwill Industries. The floor space within the Goodwill Industries site would need major renovations in order to install this type of system. The loading dock area would need to be closed during construction and installation of the system causing the loss of unrecoverable revenues to the company. Continued operation of the pump-and-treat system may require additional expenses on the part of Goodwill Industries. On January 12, 1995 the Charlotte- Mecklenburg Utility Department (CMUD) gave Goodwill Industries an "extension" to continue discharging treated effluent from the pump-and-treat groundwater remediation system into the city's sewer system until August 31, 1996. No indication was given by CMUD as to future extensions or reissuan~ of a permit for the discharge beyond one year. If Goodwill Industries continues ·to conduct corrective action that necessitates the discharge of treated effluent and .. the CMUD does not continue permitting the discharge into the sewer system, the company will need to pursue a separate discharge for this system. Such a discharge may require the construction of piping and pumping devices to the nearest discharge point at a surface water body. The company reports that the nearest drainage feature is Stewart Creek located approximately 700 feet downgradient from the site. In addition, this discharge would need to meet the requirements of state NPDES water quality rules in 15A NCAC 2B. Permitting and construction of a new discharge line for the present pump-and-treat system would require the additional expense of funds by the responsible party. Assuming that the option of a discharge to Stewart Creek is the most cost effective of other alternatives and the site remains eligible for state trust fund reimbursement, the responsible party may receive reimbursement through the trust fund for "reasonable and necessary costs" during permitting and construction of the discharge line. The company believes that there is immense uncertainty that best available technology will remediate the groundwaters at this site to standards within a foreseeable period of time. Goodwill Industries of the Southern Piedmont asserts that allowing natural remedial processes to degrade and attenuate substances found at the site will be no less effective a method than using technologic methods discussed and will not entail the same burdensome costs upon the company. 12 1 ,, ATTACl-fv1ENT 6 Rule .0113 (c)(7): Supp orting information that compliance would produce serious financial hardshi p without equal or gr eater public benefit: The company has submitted information in the request demonstrating that the environment, safety and public health would not be impacted by this variance. If air sparging with vapor recovery is used as an alternate cleanup method, it will necessitate the continual closing of this facility until the new system is constructed, installed, tested, and approved. The community that relies on vocational training provided by Goodwill Industries of the Southern Piedmont will not have access these resources. The Groundwater Section believes that the public will not benefit from compelling the Goodwill Industries of the Southern Piedmont to remediate this site using pump-and-treat technology or alternatives discussed. Rule .0113 (c)(8): "A co py of anv Special Order ... ": No Special Order by Consent has been issued for this site. Rule .0113 (c)(9): "A list of names and addresses of pro pertv owners ... ": The property owners within the proposed area of the variance are shown in Table # 1 that was revised on November 17, 1995 in a letter and includes the Dixie Electric Company, the D&L Appliance Company, the Suburban Propane Gas Corporation, the North Carolina Department of Transportation, CSX Railroad Incorporated, the E.F. Lombardi Company, and Goodwill Industries of the Southern Piedmont. Title ISA NCAC 2L .0113(e)(E) requires that notification of a public hearing on this variance be given to these adjacent property owners "at least 30 days prior to the date of the hearing". It is the recommendation of the Groundwater Section that the subject variance request to Corrective Action requirements of 15A NCAC 2L .01060) and Groundwater Quality Standards contained in 15A NCAC 2L .0202 proceed to public notice in accordance with 15A NCAC 2L .0113(e). Please note that the Mooresville Re gional Office has recommended that this variance be granted u pon the condition that an additional monitoring well be installed. It has further been recommended that this well be installed south of the well identified as Recovery Well# 5 (RW #5 ) and that "selected wells be sam pled semi-annuall y fo r several years". On October 6, 1995 the Division of Epidemiology completed their review of the risk assessment methodology for this site and recommended that this variance be granted for 13 ATTACl-f>1ENT6 ) ·-... ",-Goodwill Industries of the Southern Piedmont. Upon your concurrence with our recommendation, the Groundwater Section will proceed with the preparation of the required public notice and hearing. Upon completing of the requirements of 15A NCAC 2L .0113(d - f), with a recommendation to grant this variance from the Environmental Management Corn.mission Groundwater Committee, this request will proceed to the Environmental Management Commission for final action in 15A NCAC 2L .0113(g).

Attached is a variance request on behalf of the Goodwill Industries of the Southern Piedmont from SM&E Incorporated. The. request for variance is to groundwater standards for Benzene, Ethylbenzene, Toluene, Xylene (-o,-m, and -p), Naphthalene, Methyl Tert-Butyl Ether, Dimethyl Phthalate, and 1,2- Dichlorobenzene. The request is for a site contaminated by a release from a 2,000 gallon underground storage tank used to store diesel fuel. The area for which the variance request has been made is entirely within the property boundaries of the Goodwill Industries of the Southern Piedmont. This facility has been primarily used to assist and provide vocational training to handicapped persons. According to information submitted by the company, Goodwill Industries is within a heavily industrialized area of the City of Charlotte. Monitoring well data indicates contamination in excess of groundwater standards in 15A NCAC 2L .0202. Goodwill Industries of the Southern Piedmont does not believe that any public benefit can be gained through continued groundwater remediation efforts. Please review the attached report and provide the Groundwater Section with a r~commendation regarding this request. If possible, the Section would like to receive your response by October 13, 1995. Upon receiving your recommendation, the Section will forward a recommendation to the Director of the Division of Environmental Management.

Hance ,Y/p -Goodwill Industries Hearing Officer's Report for the Variance Request December 9, 1996 Here are some PROPOSED changes to the hearing officers report that you sent me in November 1996. Most changes are editorial in nature or for clarification. I expanded on your thoughts in the fourth and fifth paragraphs to include my discussions with Barbara Christian and Arthur Mouberry. Included in Attachment# 2 is a "Proceedings of the Hearing" with the . registration list. I also recommend we have an Attachment # 6 that will provide the EMC niore information about this site if they wish to examine it more closely. DID YOU REQUEST ADDITIONAL MONITORING DATA FOR THIS SITE? WE MAY WANT TO INCLUDE THIS IN THE DISCUSSION OR DO WE???? The copy marked DRAFT-SUBJECT TO REVISIONS for your review. A clean copy of this report with the attachments is also included. If you have no cltanges, please sign the clean copy and mail it back to me. IF we need to make corrections call me at 919-715-6189 or send an EMAIL TO ME with that information. Once we have a report that you are satisfied with we will send this toArthur Mouberry and Preston Howard so it may go before the EMC Groundwater Committee on Feburary 13, 1997. lfthe EMC Groundwater Committee gives it's approval in February, the earliest time this variance can proceed to the full EMC is March 13, 1997. Sorry for not getting to it sooner but Risk Based Corrective Action rulemaking had priority. cc: Carl Bailey PUBLIC HEARING A public notice was published advising interested parties that a public hearing was scheduled on March 19, 1996 (Attachment 1). The public hearing was conducted as scheduled. The Division was represented by four staff members: Sherri Knight Allen Schiff Keith Overcash David Hance Hearing Officer Mooresville Regional Office Mooresville Regional Office Recorder The hearing was attended by four citizens representing Goodwill Industries of the Southern Piedmont and their consulting firm S&ME (Attachment2). No one present requested to make verbal comments. Opening remarks were given by the hearing officer, followed by the staff presentation by Allen Schiff (Attachment 3). No written comments were received during the hearing and only one was received prior to the closing of the hearing record on April 19, 1996 (attachment 4). In general, the written comments, submitted by James Ponder, project geologist with S&ME, proposed a semi-annual monitoring schedule for one year followed by annual sampling thereafter. These recommendations were based upon discussions with Mooresville Regional Office staff. The comments also addressed specific analytical methods to be used and the infeasibilty of installing an additional monitoring well. On June 21, 1996, the North Carolina General Assembly enacted Senate Bill 1317 into law that allows clean-up activities (including monitoring) to be temporarily suspended pending adoption of risk assessment rules for UST sites classified as 'CDE'. Based upon ~~de~~~ the Mooresville Regional Office prepared a memorandum revising previous recommendations for monitoring requirements contingent upon variance approval. DISCUSSION/RECOMMENDATION The two issues before the Environmental Management Commission (EMC) are whether to grant a variance from the Groundwater quality standards for benzene, toluene, ethylbenzene, xylenes, naphthalene, dimethyl phthalate and 1,2 Dichlorobenzene as found in NCAC 2L .0202 and a variance from the requirement to continue to implement a corrective action plan using the best available technology as required by NCAC 2L .0106 (j). A total of $371,896 has been expended to clean-up this site, approximately $294,774 incurred from the State Underground Storage Tank Trust Fund. This included contaminated soil removal to the extent practicable and groundwater extraction and treatment. Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that continued operation of best available technology will not result in significant long term remediation of the site to the groundwater quality standards in 15 A NCAC 21 .0202 and contend that continued operation of the existing system will be a serious financial burden without equal or greater public benefit. Contaminated soil (1154 tons) has been excavated and disposed of appropriately. A groundwater pump and treat system was in operation for approximately 18 months and treated in excess of 2 million gallons of water. There has been no significant increase of contaminants since the system has been shut down. The contaminated groundwater plume is limited to the site and has not impacted off-site properties at this time. Groundwater modeling predicts that it would take 10 years for the contaminant plume to reach adjoining property assuming no attenuation or degradation of the contaminants. This variance request applies only to an area of property owned by Goodwill Industries of the Southern Piedmont. Based upon the low site priority ranking, the limited areal extent of contamination, the ability of the contaminants to attenuate, and the financial burden of continued remediation without significant environmental improvement, it is my recommendation that the EMC consider granting the variance request without further monitoring requirements.

Groundwater Incident No. 8094 Mecklenburg County, N.C. On October 13, 1995, the MRO forwarded you a variance request for the subject site along with the MRO's recommendation that selected monitor wells be sampled semi-annually if the variance was approved. Upon further review of the variance request and 15A NCAC 2L .0113 the MRO feels that the variance should be approved without any further monitoring for the following reasons: 1. The groundwater contaminant plume does not extend offsite. 2. The contaminant plume, for the most part, exists under the Goodwill building. 3. Goodwill has calculated that it would take ten years for any contaminants to reach the adjoining downgradient property, assuming no attenuation or degradation. 4. Goodwill has also calculated that it would take 63 years for the contaminants to reach the nearest surface water body, assuming no attenuation or degradation. 5. Public water supply lines in the area of the Goodwill facility are buried too shallow to be impacted by contaminants found at the site. 6. 1154 tons of contaminated soils have been excavated and disposed of at a permitted facility. 7. A groundwater pump and treat system was in operation from November 1, 1993 until May 5, 1995. This system treated a total of 2,108,185 gallons of groundwater during its operation . No significant increase of contaminants has occurred since the system has been shut off. ... : ,_;,:·~ ·--· ;·, i \3 _.,. ·:· ~.-.. 8.

In summary, this is a very low priority setting, the minimal contaminants remaining are known to be biodegradable, and we were incorrect in our assumption that monitoring would always be required upon granting of a variance resulting in our concurrence with the proposed monitoring.

Box 7668 Charlotte, NC 28241-7668 Dear Mr. Ponder: Regarding: September 6, 1996 Proposed Monitoring Requirements by the Mooresville Regional Office as a Condition for Approval of the Variance Request For Goodwill Industries of the Southern Piedmont and the Impact of Senate Bill 131 7 (GW Incident Number # 8094). You will recall that, on behalf of the Environmental Management Com.mission, the Groundwater Section held a public hearing on March 1 9, 1996 concerning a proposed variance for the Goodwill Industries of the Southern Piedmont for property located at 2122 Freedom Drive in Charlotte, North Carolina. At that hearing it was recommended by the Mooresville Regional Office that an additional monitoring well be installed south of the Goodwill Industries Building. On April 4, 1996 you sent the Groundwater Section a letter stating that the installation of that monitoring well is not "feasible". On June 21, 1996 the North Carolina General Assembly enacted Senate Bill 1317 into law that allows for cleanup activities to be temporary suspended pending adoption of risk assessment rules. Monitoring under cleanup requirements may be suspended at these sites. On July 24, 1996, you informed the staff that this site is priority ranked as "E" and in accordance with Senate Bill 1317 is "Class COE". You requested that the Groundwater Section review the necessity for recommending monitoring requirements to the Environmental Management Commission as a condition on the approval of the variance request, in light of the passage of this legislation. During a discussion with David Hance you expressed the view that since Section 1 (d) of Senate Bill 1317 restricts the Environmental Management Commission from requiring cleanup and monitoring as a part of a cleanup plan at a Class CDE site, then the law must also extend to monitoring conditions that would be applied by the Environmental Management Commission to a Groundwater Section.

The staff review of this site shows that it has a priority ranking of "E " according to information that the Groundwater Section has on file. It is important to note that Senate Bill 1317 specifically includes cleanups at sites where petroleum has been discharged or released from underground storage tanks. This law does not specify any new requirements for variances proposed to the environmental management commission pursuant to 15A NCAC 21.0113. The statutory basis for the Environmental Management Commission to grant variances is found in North Carolina General Statute (NCGS) 143- 215.3(e). Senate Bill 1317 does not mention this statute nor does it effect any actions taken by the Environmental Management Commission pursuant to NCGS 143-215.3(e). In light of these facts, there are three courses of action that the Goodwill Industries of the Southern Piedmont can take that will result in a corrective action plan that will satisfy the requirements of 15A NCAC 2L, which are shown as follows: 1) Goodwill Industries of the Southern Piedmont could withdraw the variance and discontinue cleanup for Groundwater Incident # 8094 until a risk assessment rule has been established. Senate Bill 1317 requires that by October 1, 1997 the Environmental Management Commission adopt a rule to implement the requirements of NCGS 143-215.94V(b). Please note that the deferment of cleanup requirements is a temporary, not a permanent deferment. It is not known at this time what requirements will be included in a new risk assessment rule. It must be further noted that if a risk assessment were conducted at this site and it showed that conditions are such that the site posses a higher risk than that of a site ranked Class CDE, this may result in a re-ranking to Class AB status. A higher ranking at a site may result in the reinstatement of active groundwater remediation. A risk assessment may also result in the necessity for expanded monitoring requirements. After a risk assessment rule has been adopted, a new variance may also be requested only if a new risk based rule allows responsible parties to obtain variances for releases from petroleum underground storage tanks. 2) Goodwill Industries of the Southern Piedmont could withdraw the variance for 2 Groundwater Incident # 8094 and cleanup the site pursuant to the requirements of 15A NCAC 2L. It must be noted that SB 131 7 allows, but does not require, the temporary cessation of remediation activities. Payments for cleanup out of the state's underground storage tank cleanup funds will cease unless Goodwill Industries of the Southern Piedmont can meet the criteria outlined in Section 1 (f) of Senate Bill 1317. After a risk assessment rule has been adopted, a new variance may also be requested only if a new risk based rule allows responsible parties to obtain variances for releases from petroleum underground storage tanks. 3) Goodwill Industries of the Southern Piedmont could continue to pursue a variance at this property. If a variance is granted by the Environmental Management Commission for this site, any conditions upon the variance, including monitoring, would need to be adhered ·to by the company in order for a variance to remain legally valid. After a variance is granted the responsible party may be allowed to conduct a risk assessment under the new rules to determine if the variance is still necessary. If a risk assessment, shows that the variance or monitoring requirements placed by the Environmental Management Commission as conditions for the approval of a variance are no longer needed, then Goodwill Industries may request that the variance be rescinded. In order to complete activities shown in either Number 1 or 2 above to support a new variance request pursuant to 15A NCAC 2L .0113, the most up-to-date site i1:1formation must be submitted with the information submitted through April 4, 1996. If a risk assessment is conducted pursuant to Senate Bill 1317 for any of these three scenarios, it must be in accordance with a new rule approved by the Environmental Management Commission. The most recent site information will need to be submitted in accordance to the requirements of the rule. At this time no new risk assessment rule has been p ro posed by the Division of Water Quali ty . If a decision by the Environmental Management Commission concerning this variance is unacceptable, then Goodwill Industries of the Southern Piedmont may file a petition for a contested case pursuant to ISA NCAC 2L .Ol 13(h). 3 The Groundwater Section would like to know in writing if Goodwill Industries of the Southern Piedmont desires to continue pursuing a variance for Groundwater Incident Number 8094 at this time. The hearing officer for this variance, Ms. Sherri Knight, is in the process of completing the review the Goodwill Industries request. She has been examining the groundwater monitoring data from April 4, 1996. Upon the completion of the hearing officers report and recommendation, this variance will be sent to the Environmental Management Commission for review and final action. ff possible, we would like to receive the response to this letter by September 20, 1996. Please send your response to Mr. David Hance, P.O. Box 29578, Raleigh, NC 27626-0578 {phone: (919) 715-6189; fax (919)715-0588}.

(S&ME), on behalf of Goodwill Industries of the Southern Piedmont, Inc., submits results for the first semi-annual groundwater sampling event conducted at the above referenced site on April 17, 1996. The semi-annual sampling was proposed in S&ME's Submittal of Written Statements for Variance letter, dated April 4, 1996 and submitted to Division of Environmental Management (Mr. David Hance). Results for the monitor well sampling event indicate that the relative concentrations of dissolved hydrocarbons have not changed significantly. No dissolved hydrocarbons were detected on-site in the down gradient monitoring well (MW-7). The final semi-annual sampling event is scheduled for November 1996, with subsequent sampling performed annually .

Monitoring Wells Sampling Results Goodwill Industries Ground Water Flow Direction S&ME Project 1354-93-410 June 12, 1996 S&ME visited the site on April 17, 1996 and obtained depth to groundwater surface measurements in shallow monitoring wells MW-1 through MW-7. The site location is shown in Figure 1 and the monitoring and recovery well locations are shown in Figure 2. Table 1 presents the depth to groundwater measurements and elevation data obtained in each of the se_ven shallow monitoring wells. Based on measurements the ground water flow direction in the surficial aquifer is southeast under a hydraulic gradient of approximately 0.038. These results are consistent with previous site data. The ground water surface is illustrated in Figure 3. Ground Water Quality In accordance with the proposed sampling and analyses (S&ME's letter dated April 4, 1996), S&ME sampled seven shallow monitoring wells (MW-1 through MW-7) on April 17, 1996. S&ME purged these wells and obtained groundwater samples for laboratory analyses. The groundwater samples were submitted to IEA Laboratories, _in Cary, North Carolina. The samples were analyzed according to EPA Method 610 (naphthalene) and EPA Method 602 for purgeable aromatics (BTEX and MTBE). The ground water analytical results are summarized in Table 2. A copy of the laboratory report is attached. No dissolved hydrocarbons were detected above the laboratory quantitation limits in monitoring wells MW-1, MW-2, MW-4, MW-6 and MW-7. Concentrations of toluene (130 ug/L) and total xylenes (77 ug/L) were detected in monitoring well MW-3. These levels 2 Monitoring Wells Sampling Results Goodwill Industries S&ME Project 1354-93-410 June 12, 1996 are below the 2L ground water standards for these compounds. Monitoring well MW-5 historically contained the highest levels of dissolved hydrocarbons. This well contained concentrations of benzene (350 ug/L), ethylbenzene (11 O ug/L), total xylenes (1000 ug/L) MTBE (380 ug/L) and naphthalene (480 ug/L) on April 17, 1996. The total BTEX level (1,770 ug/L) detected on April 17, 1996 is less than half the original concentration of BTEX ( 3,927 ug/L) detected during the assessment work on May 9, 1991. Figures 4 and 5 illustrate BTEX and naphthalene isocontours based on the April 17, 1996 sampling results. The final semi-annual groundwater sampling event is scheduled for September 1996. The first annual groundwater sampling for the variance monitoring is scheduled for April 1997 . Results will be forwarded to the NCDEHNR upon receipt of the laboratory report. 3 Date 17-Apr-96 17-Apr-96 17-Apr-96 17-Apr-96 17-Apr-96 17-Apr-96 17-Apr-96 TABLE 1 GOODWILL INDUSTRIES S&M E JOB NO. 1354-93-410 Groung Water Elevations Well Top-of-Casing I Depth to Elevation Water MW-1 100.11 10.82 MW-2 104.32 12.95 MW-3 98.79 6.10 MW-4 98.60 10.63 MW-5 100.51 12.90 MW-6 98.70 9.13 MW-7 94.65 15.86 ND: Not Detected k:\ ... \ 1993\93-41 0\wl96. wk1 Corrected* Wate1 Table Elevation 89.29 91.37 92.69 87.97 87.61 89.57 78.79 P:\PERSONAL\JI MP\ 123DAT A \SPREADSH\GOODWI L\GWL0495.wk1 .

S&ME proposes to collect groundwater samples from 7 wells (MW-1 through MW-7) and water levels in all wells semiannually for one year and annually thereafter. The semi-annual sampling events will be performed during April 1996 and September 1996 to potentially coincide with the seasonal high and low groundwater levels and the annual events will be scheduled during the seasonal high groundwater levels. Additionally, we suggest that the laboratory analyses be limited to those compounds that have consistently been detected in the monitoring wells, using EPA Methods 602 (BTEX) plus MTBE and 610 for naphthalene.

RESOURCES DIVISION OF ENVIRONMENTAL MANAGEMENT Notice is hereby given of a variance application and public hearing to be held by the Department of Environment, Health and Natural Resources on behalf of the Environmental Management Commission. The hearing concerns a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the Corrective Action requirements of 15A NCAC 2L .0106 (j) for Goodwill Industries of the Southern Piedmont, Inc. The variance application from Goodwill Industries was received for review by the Department on July 28, 1995. The property where the release of petroleum product has occurred is located as follows: Enter the City of Charlotte from Interstate 85 and take Freedom Drive (US 27) toward downtown. Go 3/4 of a mile. Goodwill Industries is located at the comer of Berryhill Road and Freedom Drive. The street address for this property is 2122 Freedom Drive. Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority of 15A NCAC 2L .0113 so that it does the following: (1) Allow concentrations of Benzene, Toluene, Ethylbenzene, Xylene (-o,-m, and p ), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above 15A NCAC 2L .0202 standards as analyzed on April 13, 1995. These concentrations will be required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres ofland. Approximately one- half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest comer of the building. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of this property. The area of the plume was estimated to be approximately 60,000 square feet. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992 which was approved and implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup system. The Corrective Action Plan was approved by the Division on October 22, 1992. Beginning in May 1991 the Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site and to determine the effectiveness of groundwater cleanup. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using . pump-and treat technology. Groundwater sampling has also been conducted at recovery wells used as sumps to collect groundwater, free product, and dissolved hydrocarbons. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions. in the concentrations 1 of Naphthalene and Benzene have not been observed in recovery wells. No sigll!ficant increasf .n concentrations of substances was observed as a result of the temporary cessation of pump-and-treat operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). No known sources of drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. The company believes that the variance will not impact surface waters in the area. 2) Allow for the restoration of groundwater without requiring remedial actions in accordance with 15A NCAC 2L .0106G). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application of best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of 15A NCAC 2L .0113(c)(5). The total estimated cost of installing this technology plus one years maintenance is $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss of income. Goodwill Industries of the Southern Piedmont has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. The company does not believe that this technology is the "best available technology economically reasonable" as specified in 15A NCAC 2L .0113(c)(5). Goodwill Industries asserts that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. 2 RAF The written comment period for this variance will close at 12:00 PM (Midnight) on April 19, 1996. I am requiring that you complete the hearing officers report and the recommendation to the Environmental Management Commission Groundwater Committee by July 18, 1996. This period of time is ninety (90) days after the closing date for written public comment and allows Division staff adequate time to review you recommendation. Unless significant new site information becomes available after the public hearing or other extraordinary circumstances occur that dictate a longer review period by the hearing officer, the earliest date that this variance may be considered by the Groundwater Committee is September 11, 1996. If your review of the variance shows that there is a need for a longer review period, please contact Arthur Mou berry at (919) 715-6189. I appreciate your taking the time to conduct this hearing. The staff will be glad to assist you through the proceedings. If you have any questions, feel free to call Carl Bailey at (919) 715-6169.

ALLEN SCHIFF DAVID HANCE SUBJECT: INFORMATION TO ASSIST YOU IN THE STAFF PRESENTATION FOR THE HEARING ON THE VARIAN CE FOR THE GOODWILL INDUSTRIES OF THE SOUTHERN PIEDMONT ON MARCH 19, 1996. Here is a portion of an earlier public notice for the Goodwill Industries variance. It was modified to reduce the length of the document so as to save publication costs. However, staff felt it may assist you in preparing for the hearing. The information ts shown below: Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority of 15A NCAC 2L .0113 so that it does the following: (1) Allow concentrations of Benzene, Toluene, Ethylbenzene, Xylene (-o,-m, and p), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above 15A NGAC 2L .0202 standards as analyzed on April 13, 1995. These concentrations will be required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, Industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest corner of the building. The tank closure Investigation revealed that the tank had leaked it's contents Into surrounding soll. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of this property. The area of the plume was estimated to be approximately 60,000 square feel On April 14, 1992 Goodwill Industries of the Southern Piedmont was Informed that the Comprehensive Slte Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. Tills corrective action plan was implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation or a pump-and-treat groundwater cleanup system. Pump-and-treat technology uses a pump to convey contaminated groundwaters from beneath the land, treats these groundwaters to remove contaminants, and return the treated water to a permitted discharge. The Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte-Mecklenburg Utility Department issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the beginning on May 8, 1991. The Division also required Goodwill Industries to evaluate the effectiveness of groundwater cleanup efforts by examlnlng concentrations of substances In recovery wells. Recovery wells at the Goodwill Industries slte are used as sumps to collect groundwater, free product, 1 .. and dissolved hydrocarbons from the site. Pumps convey this fluid to the treatment system. Samples were obtained from six recovery wells located beneath the building, parking lot, and loading dock areas. Groundwater cleanup using pump-and- treat technology began on May 8, 1991. From May 8, 1991 through September 21, 1994 there was no significant increase or decrease in concentrations of Benzene and other substances at on-site monitoring wells. The downgradient monitoring well located offsite to the southeast next to Freedom Drive did not show concentrations of any substances during this period. Based on groundwater analysis from May 8, 1991 through September 21, 1994 the Division of Environmental Management recommended the pump-and-treat system be turned off to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily turned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzene in all six recovery wells showed a significant decrease during this sampling event. Routine analysis of groundwater samples on April 13, 1995 showed that concentrations of substances had not been significantly reduced since 1994. Three of seven monitoring wells showed concentrations of Benzene above the Groundwater Q.uality Standards of 15A NCAC 2L .0202. The highest concentration in groundwater for a single monitoring well was 0.004 milligrams per liter. The Groundwater Quality Standard for Benzene ls 0.001 milligrams per liter. Samples from the six recovery wells continued to show levels of Benzene above Groundwater Quality Standards. Naphthalene was found at a recovery well beneath the building at a concentration of 0.029 milligrams per liter. The Groundwater Quality Standard for Naphthalene is 0.021 milligrams per liter. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations or substances was observed as a result or the temporary cessation of pump-and-treat operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). Based on groundwater flow information obtained during the Comprehensive Site Assessment it is believed that the contaminant plume is moving to the southeast. Goodwill Industries of the Southern Piedmont has calculated that It will take 10 years for the substances to reach the downgradient property boundary. The company also asserts that It will take approximately 63 years for these constituents to reach the nearest tributary of the Catawba River which ls Stewart Creek, assuming no natural degradation or attenuation occurs in the subsurface. No known sources of drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. 2) Allow for the restoration of groundwater without requiring remedial actions in accordance with 15A NCAC 2L .0106(i). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application or best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in 15A NCAC 2L .0202. The is due to the high probability that continued remediation activities at the site will not significantly reduce contaminant levels below Groundwater Quality Standards in 15A NCAC 2L .0202. Since discovery or the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,185 gallons of groundwater to comply with the cleanup requirements or the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation or the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. Goodwill Industries of the Southern Piedmont has considered the use of alr sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of 15A NCAC 2L .0113(cX5). This ls because design and installation of an air sparging system would need to consider that contaminants at this site are located directly below the building used to house Goodwill Industries. The company believes that the use of vapor extraction at this site would necessitate additional measures to protect workers from harmful concentrations of substances inside the building. The costs required to continually control vapor flow within the plant and the potential risk to workers offsets any inherent benefits of this cleanup method. Goodwill Industries of the Southern Piedmont has furnished cost information for an air sparging system with vapor extraction. The total estimated cost or installing this technology plus one years maintenance ls $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss or income. 2 NOT E: 03/11/96 TO: FROM; IMPOR TANT !!!!!!

THANK YOU I f/4JtJ~ David Hance cc: Carl Bailey 1 NOTICE OF VARIANCE APPLICATION AND HEARING DEPARTMENT OF ENVIRONMENT, HEALTH AND NATURAL RESOURCES DIVISION OF ENVIRONMENTAL MANAGE1IBNT Notice is hereby given of a variance application and public hearing to be held by the Department of Environment, Health and Natural Resources on behalf of the Environmental Management Commission. The hearing concerns a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the Corrective Action requirements of ISA NCAC 2L .0106 G) for Goodwill Industries of the Southern Piedmont, Inc. The variance application horn Goodwill Industries was received for review by the Department on July 28, 1995. The property where the release of petroleµm product has occurred is located as follows: Enter the City of Charlotte from Interstate 85 and tak~ freedom Drive (US 'l.7) toward downtown. Go 3/4 of a mile. Goodwill Industries is located at the corner of Berryhill Road and Freedom Drive. The street address for this property is 2122 Freedom Drive which is listed as in land maps as Parcel Numt>er 071-063-13. Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority of 15A NCAC 2L .0113 so that it does the following: (1) Allow concentrations of Benzene, Toluene, Ethyl benzene, Xylene (-o,-m, and p ), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above 15A NCAC 2L .0202 standards as analy zed on April 13, 1995. These concentrations will be required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered hf"'the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest corner of the building. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of t hls property. The area of the plume was estimated to be approximately 60,000 square feet. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. This corrective action plan was implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup system. Pump-and-treat technology uses a pump to convey 1 contaminated groundwaters from beneath the land, treats these groundwaters to remove contaminants, and return the treated water to a permitted discharge. The Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte-Mecklenburg Utility Department issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the beginning on May 8, 1991. The Division also required Goodwill Industries to evaluate the effectiveness of groundwater cleanup efforts by examining concentrations of substances in recovery wells. Recovery wells at the Goodwill Industries site are used as sumps to collect groundwater, free product, and dissolved hydrocarbons from the site. Pumps convey this fluid to the treatment system. Samples were obtained from six recovery wells located beneath the building, parking lot, and loading dock areas. Groundwater cleanup using pump-and-treat technology began on May 8, 1991. From May 8, 1991 through September 21, 1994 there was no significant increase or decrease in concentrations of Benzene and other substances at on-site monitoring wells. The downgradient monitoring well located offsite to the southeast next to Freedom Drive did not show concentrations of any substances during this period. Based on groundwater analysis from May 8, 1991 through September 21, 1994 the Division of Environmental Management recommended the pump-and-treat system be turned off to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily turned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzene in all six recovery wells showed a significant decrease during this sampling event. Routine analysis of groundwater samples on April 13, 1995 showed that concentrations of substances had not been significantly reduced since 1994. Three of seven monitoring wells showed concentrations of Benzene above the Groundwater Quality Standards of 1 SA NCAC 2L .0202. The highest concentration in groundwater for a single monitoring well was 0.004 milligrams per liter. The Groundwater Quality Standard for Benzene is 0.001 milligrams per liter. Samples from the six recovery wells continued to show levels of Benzene above Groundwater Quality Standards. Naphthalene was found at a recovery well beneath the building at a concentration of 0.029 milligrams per liter. The Groundwater Quality Standard for Naphthalene is 0.021 milligrams per liter. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). Based on groundwater flow information obtained during the Comprehensive Site Assessment it is believed that the contaminant plume is moving to the southeast. Goodwill Industries of the Southern Piedmont has calculated that it will take 10 years for the substances to reach the downgradient property boundary. The company also asserts that it will take approximately 63 years for these constituents to reach the nearest tributary of the Catawba River which is Stewart Creek, assuming no natural degradation or attenuation occurs in the subsurface. No known sources of 2 drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. 2) Allow for the restoration of groundwater without requiring remedial actions in accordance with 15A NCAC 2L .0106G). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application of best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in 15A NCAC 2L .0202. The is due to the high probability that continued remediation activities at the site will not significantly reduce contaminant levels below Groundwater Quality Standards in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of 15A NCAC 2L .0113(c)(5). This is because design and installation of an air sparging system would need to consider that contaminants at this site are located directly below the building used to house Goodwill Industries. The company believes that the use of vapor extraction at this site would necessitate additional measures to protect workers from harmful concentrations of substances inside the building. The costs required to continually control vapor flow within the plant and the potential risk to workers offsets any inherent benefits of this cleanup method. Goodwill Industries of the Southern Piedmont has furnished cost information for an air sparging system with vapor extraction. The total estimated cost of installing this technology plus one years maintenance is $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss of income. Goodwill Industries of the Southern Piedmont has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. Enhanced in-situ bioremediation involves the introduction of nutrients and oxygen into groundwater through injection wells to assist in building a viable population of microorganisms that break down chemicals. The company does not believe that this technology is the "best available technology economically reasonable" as specified in 15A NCAC 2L .0113(c)(5). Goodwill Industries asserts that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. Investigative work to get the appropriate injection well permits under 15A NCAC 2C .0200 (Criteria and Standards Applicable to Injection Wells) would involve extensive geologic evaluation, groundwater flow modeling, geochemical studies, and site- 3 specific engineering to develop an appropriate injection well field. In addition, the company would need to demonstrate that in-situ bioremediation will degrade contaminant below concentrations listed in 15A NCAC 2L .0202 in order to meet the requirements of 15A NCAC 2L .0106(1). To do this Goodwill Industries would need to conduct a detailed study of the biologic processes in the soil and subsurface to assure that the site can support organisms that biologically breakdown substances. The hearing will be held as follows: CHARLOTTE MARCH 19, 1996 7:00 PM Mecklenburg County Courthouse -Criminal Courts Building 2nd Floor -Courtroom 2201 700 East Fourth Street Oral Comments may be made during the hearing, or written statements may be submitted to the agency by April 19, 1996.

The hearing concerns a request for a variance from the Groundwater Quality Standards of 15A NCAC 2L .0202 and the Corrective Action requirements of 15A NCAC 2L .0106 G) for Goodwill Industries of the Southern Piedmont, Inc. The variance application from Goodwill Industries was received for review by the Department on July 28, 1995. The property where the release of petroleum product has occurred is located as follows: Enter the City of Charlotte from Interstate 85 and take Freedom Drive (US 27) toward downtown. Go 3/4 of a mile. Goodwill Industries is located at the comer of Berryhill Road and Freedom Drive. The street address for this property is 2122 Freedom Drive. Goodwill Industries requests that the Environmental Management Commission grant the following variance to it's rules under the authority of 15A NCAC 2L .0113 so that it does the following: (1) Allow concentrations of Benzene, Toluene, Ethyl benzene, Xylene (-o,-m, and p ), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene to remain at levels above 15A NCAC 2L .0202 standards as analyzed on April 13, 1995. These concentrations will be required to remain within the property boundaries of the Goodwill Industries of the Southern Piedmont. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one- half of the land area is covered by the building that houses Goodwill Industries. Goodwill Industries of the Southern Piedmont is located within an area with a mixture of commercial, industrial, and residential development. On November 21, 1991 Goodwill Industries removed a 2,000 gallon underground storage tank containing diesel fuel that was located at the northwest corner of the building. The tank closure investigation revealed that the tank had leaked it's contents into surrounding soil. In August 1991 a Comprehensive Site Assessment was completed and revealed a plume of groundwater contamination beneath the building and parking lot of this property. The area of the plume was estimated to be approximately 60,000 square feet. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992 which was approved and implemented on September 6, 1992. Goodwill Industries later submitted a separate Corrective Action Plan was submitted to the Division on July 2, 1992 to cleanup groundwater. The plan called for the implementation of a pump-and-treat groundwater cleanup system. The Corrective Action Plan was approved by the Division on October 22, 1992. Beginning in May 1991 the Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site and to determine the effectiveness of groundwater cleanup. Monitoring wells at this site have shown insignificant reductions in Benzene as a result of using pump-and treat technology. Groundwater sampling has also been conducted at recovery wells used as sumps to collect groundwater, free product, and dissolved hydrocarbons. Although concentrations of substances appear to be decreasing in recovery wells, significant reductions in the concentrations 1 of Naphthalene and Benzene have not been observed in recovery wells. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat operations. On July 28, 1995 Goodwill Industries submitted a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0l 13(b). No known sources of drinking water from water wells or surface water supplies are known to exist within a 1/2 mile radius of this property. The Charlotte-Mecklenburg Utilities Department has indicated that the average depth of public water supply lines in this area are four feet from the ground surface and are too shallow to be impacted by constituents found in groundwater beneath Goodwill Industries. The company believes that the variance will not impact surface waters in the area. 2) Allow for the restoration of groundwater without requiring remedial actions in accordance with 15A NCAC 2L .0106(j). Goodwill Industries of the Southern Piedmont has submitted supporting information demonstrating that the continued application of best available technology will not result in significant long term remediation of the site to the Groundwater Quality Standards contained in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated an estimated 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Goodwill Industries reports that a total of $371,896 has been expended to cleanup this site. This total cost includes approximately $294,774 that was incurred to the State's Underground Storage Tank Trust Fund. Goodwill Industries has shown that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted the groundwater data indicated no increase in the concentration of any constituent in monitoring wells. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is economically reasonable or practical to meet the requirements of 15A NCAC 2L .0113(c)(5). The total estimated cost of installing this technology plus one years maintenance is $100,000. In addition, the company believes that installation of this technology will necessitate the temporary closing of the facility and result in the subsequent loss of income. Goodwill Industries of the Southern Piedmont has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. The company does not believe that this technology is the "best available technology economically reasonable" as specified in 15A NCAC 2L .0l 13(c)(5). Goodwill Industries asserts that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. 2 FEF: [1?

The report titled "Variance Request Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Proiect No. 1354-93-410 contains the relevant information about this site. This facility is at the corner of Freedom Drive and· Berry Hill Road as shown in Figure 1 of Appendix in the report from S&ME Incorporated. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. The former owner of this location was A.G. Boone Trucking Company. A 2,000 gallon underground storage tank containing diesel fuel was at the northwest corner of the building. This underground storage tank was removed on November 21, 1990 and the release was subsequently discovered upon tank closure. Goodwill Industries does not have any other underground storage tanks on this property. No other existing or potential sources of groundwater contamination were identified at this property by Goodwill Industries. Goodwill Industries of the Southern Piedmont and all adjacent properties are in an area with a mixture of commercial, industrial, and residential development. The tank closure report documented the removal of 240 tons of soil contaminated with diesel fuel. Analytical tests of soils within the excavation area did not indicate contamination below 21 feet from the ground surface. In August 1991 a Comprehensive Site Assessment was completed. The site assessment revealed a groundwater plume from a small area of contamination adjacent to the building. This area of contamination was at the northwest corner of Goodwill Industries near the companies loading dock and adjacent to the area where the diesel fuel pump had been located. The area of the plume was estimated to be approximately 60,000 square feet ( 400 feet long by 150 feet long). Monitoring indicated that the vertical extent of this plume was approximately 44 feet below the ground surface. The company estimated that approximately 5,924,952 gallons of groundwater had been contaminated by the release. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. From September 6, 1992 through November 9, 1992 approximately 914 tons of soil was excavated and treated offsite adjacent to the loading dock area. The treatment method used for this soil was thermal incineration. A Corrective Action Plan or "Remedial Action Plan" was submitted to the Division on July 2, 1992 to cleanup groundwater 2 using pump-and-treat technology. Implementation of the Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte Mecklenburg Utility Department (CMUD) issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perform groundwater monitoring to determine the vertical and lateral extent of contamination at the site. On September 21, 1994 the company conducted comprehensive groundwater sampling at eight monitoring wells. The deepest of the monitoring wells is known as "DMW-3" and is 44 feet below the land surface. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. Only Benzene was found in the monitoring wells. The highest concentration found in a monitoring well in exceedence of the 15A NCAC 2L .0202 Groundwater Quality Standard for Benzene during this sampling event was 0.011 milligrams/Liter in Monitoring Well# 4. The Division also required Goodwill Industries to evaluate the effectiveness of groundwater cleanup efforts by examining concentrations of substances recovery wells used as sumps to collect free product and dissolved hydrocarbons from the site. Samples were obtained from six recovery wells located beneath the building, parking lot, and loading dock areas. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. The highest Benzene concentration in a recovery well showed 0.290 milligrams/Liter at Recovery Well # 5 beneath the building. Downgradient Monitoring Well # 7 located offsite southeast next to Freedom Drive did not show any concentrations above practical quantitation levels. Based on these results the Division of Environmental Management recommended the pump-and-treat system be turned off for a period of two months to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily turned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzene in all six recovery wells showed a significant decrease during this sampling event. Based on the results of the December 1994 monitoring, Goodwill Industries of the Southern Piedmont informed the Charlotte-Mecklenburg Utilities Department (CMUD) in January 1995 that it intended to request a variance at this site. In Appendix III the January 12, 1995 memorandum from CMUD informed the responsible party that the existing permit to discharge treated groundwater into the sewer system would be extended beyond August 31, 1995 for an additional year, if the variance to terminate remediation is not granted by the Commission during the time. As shown in Appendix III, CMUD stated that the permit would be "extended" not "re-issued". On July 28, 1995 Goodwill Industries sent a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). 3 Rule .Ol 13 (c)(2): A description of past , existin g or pro posed activities that would result in a discharge of contaminants into groundwater: Goodwill Industries of the Southern Piedmont is located inside the city limits of Charlotte, North Carolina at 2122 Freedom Drive (Parcel Number 071- 063-13). The report titled "Variance Re q uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410 contains the relevant information about this site. This facility is at the corner of Freedom Drive and · Berry Hill Road as shown in F igure 1 of Appendix in th·e report from S&ME l1n~orp-orated. T he Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. The former owner of this location was A.G. Boone Trucking Company. A 2,000 gallon underground storage tank containing diesel fuel was at the northwest corner of the building. This underground storage tank was removed on November 21, 1990 and the release was subsequently discovered upon tank closure. Goodwill Industries does not have any other underground storage tanks on this property. No other existing or potential sources of groundwater contamination were identified at this property by Goodwill Industries. Goodwill Industries of the Southern Piedmont and all adjacent properties are in an area with a mixture of commercial, industrial, and residential development. The tank closure report documented the removal of 240 tons of soil contaminated with diesel fuel. Analytical tests of soils within the excavation area did not indicate contamination below 21 feet from the ground surface. In August 1991 a Comprehensive Site Assessment was completed. The site assessment revealed a groundwater plume from a small area of contamination adjacent to the building. This area of contamination was at the northwest corner of Goodwill Industries near the companies loading dock and adjacent to the area where the diesel fuel pump had been located. The area of the plume was estimated to be approximately 60,000 square feet ( 400 feet long by 150 feet long). Monitoring indicated that the vertical extent of this plume was approximately 44 feet below the ground surface. The company estimated that approximately 5,924,952 gallons of groundwater had been contaminated by the release. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. From September 6, 1992 through November 9, 1992 approximately 914 tons of soil was excavated and treated offsite adjacent to the loading dock area. The treatment method used for this soil was thermal incineration. A Corrective Action Plan or "Remedial Action Plan" was submitted to the Division on July 2, 1992 to cleanup groundwater 2 Potential sources of groundwater contamination in the area are shown in Figure 2 in the report "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" and include the following: 1) A retail gasoline station presently owned by Servco located approximately 800 feet northwest of Goodwill Industries on Freedom Drive; 2) A fuel oil tank located approximately 250 feet to the northeast from Goodwill Industries. This fuel oil tank appears to be on property owned by Flemming Laboratories Incorporated; 3) An H 2SO4 tank located approximately 250 feet to the northeast from Goodwill Industries. This chemical tank appears to be on property owned by Flemming Laboratories Incorporated; ; 4) An area containing what is described as "hazardous waste drums" approximately 250 to 300 feet to the east from Goodwill Industries. Figure # 2 appears to show that these drums are on property owned by Flemming Laboratories Incorporated. 5) Monitoring Wells owned by Flemming Laboratories Incorporated. These wells are located to the east and northeast of the Goodwill Industries site. 6) Berry Hill Road (a public roadway); 7) Freedom Drive (a public roadway); 8) A CSX Transportation Incorporated railroad line that is to the northeast and east of Goodwill Industries.

This sewer runs from northwest to southeast parallel to the Goodwill Industries property line; 10) A storm drain line that is within of few feet of the southwest property line of Goodwill industries. This storm drain runs from northwest to southeast parallel to the Goodwill Industries property line; and 4 Potential sources of groundwater contamination in the area are shown in Figure 2 in the report "Variance Re q uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" and include the following: 1) A retail gasoline station presently owned by Servco located approximately 800 feet northwest of Goodwill Industries on Freedom Drive; 2) A fuel oil tank located approximately 250 feet to the northeast from Goodwill Industries. This fuel oil tank appears to be on property owned by Flemming Laboratories Incorporated; 3) An H 2SO 4 tank located approximately 250 feet to the northeast from Goodwill Industries.

The former owner of this line was the Piedmont and Northern Railroad Company; 9) A sewer line that is within of few feet of the southwest property line of Goodwill industries. This· sewer runs from northwest to southeast parallel to the Goodwill Industries property line; 10) A storm drain line that is within of few feet of the southwest property line of Goodwill industries. This storm drain runs from northwest to southeast parallel to the Goodwill Industries property line; and 4 11) Numerous other storm drain lines and sewer lines that are in the general area. The property for which the variance is requested is entirely owned by Goodwill Industries of the Southern Piedmont. The groundwater that was impacted by the release is located beneath the building and the parking lot area. A fence is located at the northeast side of the building. Access to impacted groundwater at the site by workers, visitors, and unlawful intruders is under the control of the responsible party. Rule .0113 (c)(3): Description of the pro posed area for which the variance is re quested: This variance is for an area entirely within the property boundaries of the Goodwill Industries of the Southern Piedmont. Maps of this area are shown in Figure 3 and Appendix II of the report titled "Variance Re q uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410". The contaminated area is in the form of an ellipse with it's longitudinal axis from northwest to southeast. The southeastern side of this ellipse is within a few feet of the storm drain line and sewer line that runs alongside Freedom Drive. More specifically the area for which the variance is requested is bounded to the north by the property line with Suburban Propane Company. This area laterally extends to the northeast toward the Suburban Propane Company property line, running beneath the Goodwill Industries Building, but does not extend as far as Monitoring Well # 6. The lateral area extends southeast toward property owned by D.L. Appliance Company but not as far as Monitoring Well# 7. The southwestern boundary of this area is at the property line that runs parallel with Freedom Drive. The western extent of this area is beneath the building and does not go as far as the position of Monitoring Well # 1. The extent of the northwest boundary includes part of the asphalt parking lot but does not go beyond the site where the diesel underground storage tank pump island once existed. The lateral extent of this plume stops before it reaches Monitoring Well# 2. The concentration of contaminants in groundwater is primarily influenced by the direction and rate of groundwater flow. Goodwill Industries asserts that groundwater flow from the site travels toward a tributary of Stewart Creek approximately 700 feet to the southeast. This creek discharges into the Catawba River. The groundwater flow rate was obtained from information in the Comprehensive Site Assessment (CSA). Based on information in the CSA, Goodwill Industries of the Southern Piedmont asserts that groundwater in the area flows in a southeast direction. The 1994 groundwater monitoring results 5 from recovery wells beneath the building indicated that the contaminant plume is moving in a southeasterly direction toward Freedom Drive. The estimated groundwater flow velocity in the subsurface is approximately 11 feet/year. The company asserts that at this rate of groundwater movement the plume of petroleum hydrocarbon contamination will enter Stewart Creek in approximately 63 years, assuming no natural degradation or attenuation of the plume occurs (See page 9 of the report). Page 3 of the report states that the company does not believe that any natural geologic structures exist in the subsurface beneath the site that would have the effect of creating an impermeable boundary to groundwater movement. Goodwill Industries believes that the depth to bedrock beneath the site is between 50 and 100 feet. No other properties owned by Goodwill Industries of the Southern Piedmont or properties owned by other persons are being included in this application for variance. (refer to Appendix II of the report). Rule .0113{c)(4): Supporting information to establish that the variance will not endanger the public health and safety ... : The part of the variance concerning Groundwater Quality Standards shown in 15A NCAC 2L. 0202 has been requested for Benzene, Ethylbenzene, Toluene, Xylene(-o,-m, and p), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene. In order to assess health impacts from this site, monitoring wells were sampled at this site to assess the extent of contamination and concentration levels of substances. Concentrations of substances in recovery wells were also examine to determine the effectiveness of the pump, and treat system at removing these chemicals. Groundwater monitoring data from Goodwill Industries of the Southern Piedmont indicates that this site does not pose a hazard to the public. Sampling and analysis has been conducted since May 8, 1991 at monitoring wells and recovery wells. Three sampling events occurred in March, September, December of 1994 and the last sampling and analysis was done on April 13, 1995. USEP A Method 602 and Method 625 were the analytical methods used for samples collected at the Goodwill Industries site. USEP A Method 602 is used to assess the concentration levels of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE. USEP A Method 625 is used to examine the concentrations of phthalate compounds, 1,2-Dichlorobenzene, Base/Neutral Extractables, and Naphthalene. The highest concentration of any substance found at this site was 0.590 milligrams per liter (mg/L) or 590 micrograms per liter (ug/L) of Dimethyl Phthalate in Recovery Well# 5. The Groundwater Quality Standard for this substance is zero pursuant to 15A NCAC 2L .0202(c). The lateral extent of this reported contamination is shown in Figure 4 of Appendix II. Dimethyl Phthalate was not detected in any other recovery wells or in monitoring wells during this sampling event. Analysis of subsequent groundwater samples in 1994 and 1995 6 did not reveal Dimethyl Phthalate contamination in Recovery Well# 5, other recovery wells, or monitoring wells. In Table 2 of the report, the December 9, 1994 groundwater sampling was conducted at monitoring wells showed the concentrations of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE below their respective Groundwater Quality Standards in 15A NCAC 2L .0202. None of the monitoring wells showed concentrations of these substances above practical quantitation limits. The only wells that showed any concentration levels above Groundwater Quality Standards in 15A NCAC 2L .0202 from the USEP A Method 602 analysis were the recovery wells (RW #1 through RW # 6). The highest concentration in any single recovery well during this period was 0.071 milligrams per Liter (mg/L) or 71 micrograms per Liter (ug/L) at RW # 5. The analysis of samples using USEP A Method 625 did not reveal any concentrations of phthalate compounds, 1,2-Dichlorobenzene, or Naphthalene in the monitoring wells above the Groundwater Quality Standards in 15A NCAC 2L .0202. Base/Neutral extractable compounds, such as Anthracene, did not appear in concentrations above Groundwater Quality Standards or Interim Maximum Allowable Concentrations in any of these wells. Recovery Well# 5 showed Naphthalene at 0.062 mg/Lor 62 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). This recovery well is located in the center of the building which houses Goodwill Industries of the Southern Piedmont. It is important to note that this December 1994 sampling event bad occurred some time after the pump-and-treat system had been temporarily turned off pursuant to the Division's instructions. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat cleanup. On April 13, 1995 Goodwill Industries conducted a routine sampling of monitoring and recovery wells at the site. Table 2 shows results from USEP A Method 602 analysis. Three monitoring wells (MW # 3, DMW # 3, and MW # 4 had concentrations of Benzene above the Groundwater Quality Standard of 0.001 mg/L (1 ug/L). Monitoring Well# 4 had the highest concentration of Benzene at 0.004 mg/Lor 4 ug/L. Recovery Wells #1 through# 6 showed levels of Benzene above the Groundwater Quality Standard established by 15A NCAC 2L .0202. USEP A Method 625 analysis did not reveal any chemicals in monitoring wells above practical quantitation limits. Table 2 shows that Naphthalene continues to be present in Recovery Well # 5 at a concentration above the standard in 15A NCAC 2L .0202. Naphthalene was found in this well at 0.029 mg/L or 29 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). No other recovery wells have shown any constituents in exceedence of the standards contained in 15A NCAC 2L .0202 as a result of analysis using USEP A Method 625. Goodwill Industries of the Southern Piedmont has attempted to define the vertical extent of groundwater contamination beneath the site. The deepest well (DMW # 3) is 44 feet below the ground surface. Groundwater sampling and analysis was conducted using USEP A Method 602 and Method 625 at three 7 separate times in 1994 as shown in Table# 2. The analysis of the September 21, 1994 sampling event for DMW #3 showed a concentration of Benzene at 0.003 milligrams per liter. This level is in exceedence of the Groundwater Quality Standard of 0.001 milligrams per liter for this substance in 15A NCAC 2L .0202. The analysis of all other samples taken from this well in 1994 did not reveal any other chemical constituent from the petroleum release. A semi-annual sample was taken on April 13, 1995 at the monitoring well DMW # 3 and showed a Benzene concentration at 0.002 mg/L or 2 ug/L. No other substances normally associated with a release of diesel fuel were found in this monitoring well during the April 1995 sampling. (see Table 2 of the report). Page 8 of the report states that the downgradient recovery well (RW # 6) has not shown " ... any EPA Method 625 compounds and only 28 ug/1, of benzene ... ". Analysis of samples from the downgradient monitoring well MW # 7 has not shown any substances as a result of using USEP A Method 602 or Method 625. Based on the groundwater flow velocity of 11 feet per year from the site assessment, the company estimates that the time it will take the petrochemical plume to reach monitoring well # 7 is 4.5 years. Goodwill Industries believes . that it will take a 'total of 10 years for the substances to reach the downgradient property boundary. These estimates are based on conservative assumptions that the plume will not be impacted by natural remedial processes and attenuation effects within the subsurface. It is not anticipated that rainfall events will significantly impact the movement of contaminants offsite. The area where groundwater monitoring results showed concentrations of Benzene, Naphthalene, and Dimethyl Phthalate above the standards is beneath the building that houses Goodwill Industries of the Southern Piedmont. The area outside this structure is covered by an asphalt driveway and parking area. No sources of drinking water from water wells or surface water are known to exist.within a 1/2 mile radius of the Goodwill Industries of the Southern Piedmont. The requirements for variance applications in 15A NCAC 2L .0113(c)(4) specify that locations of drinking water wells and other water supply sources that are within one-half mile of the site must be shown on a map. The report from Goodwill Industries states that there are no drinking water wells within one-half mile of the site for which the variance has been requested. The December 7, 1995 memorandum referencing "Private Drinking Water Information" shows that there are no drinking water supply intakes at surface water bodies located within a 1/2 mile radius of the site. Drinking water for the City of Charlotte is obtained from Mountain Island Lake on the Catawba River five miles north-northwest of the site. All downgradient properties are supplied drinking water from the City of Charlotte. There are approximately six groundwater monitoring wells near the railroad tracks and Flemming 8 Laboratories Incorporated. These are to the northeast of the Goodwill Industries and are cross-gradient from the site. It appears unlikely that the presence of these wells would result in the movement of petroleum contamination from Goodwill Industries into groundwater. It is highly improbable that public water supply lines will be impacted by this variance. The nearest water supply lines are a 20 inch line that runs parallel on Freedom Drive and an eight inch ~upply line that runs along Berry Hill Road. The Groundwater Section contacted the Administration Division at the Charlotte- Mecklenburg Utility Department (704-399-2551) and was informed that the average ·depth of these water lines from the ground surface is four feet. Groundwater contamination beneath Goodwill Industries is too deep within the subsurface to impact these lines. Rule .0113 (c )(5): Supp ortin g information to establish that re quirements of the rule cannot be achieved by providing best available technolo gy economically reasonable: The part of the request that concerns variance to Corrective Action in 15A NCAC 2L .0106(j) will allow Goodwill Industries of the Southern Piedmont to discontinue Corrective Action at this site. Goodwill Industries of the Southern Piedmont has submitted supporting information in the report and other documents demonstrating that the continued application of BAT will not result in significant long term remediation of the site to the Groundwater Quality Standards, contained in 15A NCAC 2L .0202. The is due to the high probability that continued remediation activities at the site will not significantly reduce contaminant levels below Groundwater Quality Standards in 15A NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated approximately 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Page 11 of the report titled "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" states that a total of $371,896 has been expended to cleanup this site. Goodwill Industries of the Southern Piedmont has incurred $77,122 of this total in the form of State Trust Fund deductibles and non-reimbursed items. Concentrations of substances in the groundwater have not been significantly reduced over the last year as shown in Table 2 of the report. Monitoring wells have shown insignificant reductions in Benzene using pump-and treat technology. Significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. It is also important to note that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted groundwater monitoring data indicated no increase 9 in the concentration of any constituent. In order to demonstrate that the requirements of the rule cannot be achieved using best available technology, Title 15A NCAC 2L .0113(c)(5) requires that specific technology considered be identified, the costs of implementing the technology be shown, and the impacts of the costs on the applicant be provided. Goodwill Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is practical to meet the requirements of 15A NCAC 2L .0113(c)(5). In order to meet EHNR air quality standards, an air sparging system would need to be used in conjunction with vapor extraction to prevent fugitive vapors from spreading into the environment. The company asserts that two air sparging wells would need to be located inside the building in order to have an effective remediation system. The use of vapor extraction at the Goodwill Industries site would necessitate additional measures to protect workers from harmful concentrations of substances inside the building. The costs required to continually control vapor flow within the plant and the potential risk to workers offsets any inherent benefits of this cleanup method. Pursuant to the requirements of 15A NCAC 2L .0113(c)(5), the company does not believe that air sparging with vapor extraction an "economically reasonable" technology for this site. The Goodwill Industries of the Southern Piedmont has furnished cost information for an air sparging system with vapor extraction in Table 3 of the report "Variance Request Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Proiect No. 1354-93-410". This information is summarized as follows: Technology Air Sparging System Soil Vapor Extraction System Piping & Underground Utilities Permitting, Project Management, On-Site Supervision Plus Operation and Maintenance for One-Year Total Cost ($) $21,000 $17,600 $23,000 $38,400 Estimated Total Cost = $100,000 Goodwill Industries has examined the potential effectiveness of enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. Enhanced in-situ bioremediation involves the introduction of nutrients and oxygen into groundwater. The company does not believe that this technology is the "best available technology economically reasonable" as specified in 15A NCAC 2L .0113(c)(5). If enhanced in-situ bioremediation was selected as the cleanup method for the Goodwill Industries site it would involve the use of injection wells to introduce nutrient substances into the subsurface that would assist in biodegradation. In order to permit injection wells under the current rules in 15A NCAC 2C .0200 they would have to permitted as Type 5X (Other Wells). On page 2 of a December 4, 1995 memorandum the company's environmental consultant stated that permitting of injection wells for enhanced in-situ bioremediation would require the company to conduct extensive groundwater modeling studies and geochemical modeling. In addition, a site specific design for the injection well field would need to be developed prior to obtaining a permit. In addition, a corrective action plan using in-situ bioremediation would also need to be reviewed under the criteria in 15A NCAC 2L .0106(1). This rule requires a demonstration be made to the Director of the Division of Environmental Management that the site meets the criteria of 15A NCAC 2L .0106(1) so that the health, safety, and welfare of the public would not be impacted by allowing natural remedial processes to cleanup the site. In a November 27, 1995 letter Goodwill Industries states that the investigative work required to submit this corrective action plan would involve lengthy studies of the geochemical properties of the site, flow properties of the contaminated matrix, and developing methods of measuring the contaminate concentration. A study of the feasibility of bioremediation would also need to be conducted to show that a corrective action plan under 15A NCAC 2L .0106(1) would effectively reduce contaminate concentrations to the level of the standards. The company believes that in order to determine the feasibility of in-situ enhanced bioremediation, an assessment of biologic processes in the soil would need to be examined and the toxicity of soils and sediments to these organisms would need to be assessed. Goodwill Industries believes that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. Rule .Ol 13 (c)(6): Supp orting information to establish that compliance would produce serious financial hardshi p on the app licant: In pages 10 through 12 of the report reveals that Goodwill Industries of the Southern Piedmont has demonstrated that continued application of best available technology to this site would be a prohibitively expensive method of 11 remediating groundwater contamination. Some of the plumbing for the pump- and-treat cleanup system is located in various parts of the building. Continual reliance on the pump-and-treat system will mean that Goodwill Industries will not be able to utilize this additional space for offices. Based on the previous installation of the pump-and-treat groundwater remediation system, Goodwill Industries foresees the use of an air sparging system with vapor recovery to cleanup the site resulting in a major disruption of business operations at Goodwill Industries. The floor space within the Goodwill Industries site would need major renovations in order to install this type of system. The loading dock area would need to be closed during construction and installation of the system causing the loss of unrecoverable revenues to the company. Continued operation of the pump-and-treat system may require additional expenses on the part of Goodwill Industries. On January 12, 1995 the Charlotte- Mecklenburg Utility Department (CMUD) gave Goodwill Industries an "extension" to continue discharging treated effluent from the pump-and-treat groundwater remediation system into the city's sewer system until August 31, 1996. No indication was given by CMUD as to future extensions or reissuance of a permit for the discharge beyond one year. If Goodwill Industries continues to conduct corrective action that necessitates the discharge of treated effluent and the CMUD does not continue permitting the discharge into the sewer system, the company will need to pursue a separate discharge for this system. Such a discharge may require the construction of piping and pumping devices to the nearest discharge point at a surface water body. The company reports that the nearest drainage feature is Stewart Creek located approximately 700 feet downgradient from the site. In addition, this discharge would need to meet the requirements of state NPDES water quality rules in 15A NCAC 2B. Permitting and construction of a new discharge line for the present pump-and-treat system would require the additional expense of funds by the responsible party. Assuming that the option of a discharge to Stewart Creek is the most cost effective of other alternatives and the site remains eligible for state trust fund reimbursement, the responsible party may receive reimbursement through the trust fund for "reasonable and necessary costs" during permitting and construction of the discharge line. The company believes that there is immense uncertainty that best available technology will remediate the groundwaters at this site to standards within a foreseeable period of time. Goodwill Industries of the Southern Piedmont asserts that allowing natural remedial processes to degrade and attenuate substances found at the site will be no less effective a method than using technologic methods discussed and will not entail the same burdensome costs upon the company. 12 Rule .0l 13 (c)(7): Supp orting information that com pliance would produce serious financial hardshi p without equal or greater public benefit: The company has submitted information in the request demonstrating that the environment, safety and public health would not be impacted by this variance. If air sparging with vapor recovery is used as an alternate cleanup method, it will necessitate the continual closing of this facility until the new system is constructed, installed, tested, and approved. The community that relies on vocational training provided by Goodwill Industries of the Southern Piedmont will not have access these resources. The Groundwater Section believes that the public will not benefit from compelling the Goodwill Industries of the Southern Piedmont to remediate this site using pump-and-treat technology or alternatives discussed. Rule .0l 13 (c)(8): "A co py of an y S pecial Order ... 11 : No Special Order by Consent has been issued for this site. Rule .0l 13 (c)(9 ): "A list of names and addresses of pro perty owners ... ": The property owners within the proposed area of the variance are shown in Table# 1 that was revised on November 17, 1995 in a letter and includes the Dixie Electric Company, the D&L Appliance Company, the Suburban Propane Gas Corporation, the North Carolina Department of Transportation, CSX Railroad Incorporated, the E.F. Lombardi Company, and Goodwill Industries of the Southern Piedmont. Title 15A NCAC 2L .0113(e)(E) requires that notification of a public hearing on this variance be given to these adjacent property owners "at least 30 days prior to the date of the hearing". It is the recommendation of the Groundwater Section that the subject variance request to Corrective Action requirements of 15A NCAC 2L .01060) and Groundwater Quality Standards contained in 15A NCAC 2L .0202 proceed to public notice in accordance with 15A NCAC 2L .0l 13(e). Please note that the Mooresville Re gional Office has recommended that this variance be granted u pon the condition that an additional monitoring well be installed. It has further been recommended that this well be installed south of the well identified as Recovery Well# 5 (RW #5 ) and that "selected wells be sam pled semi-annually for several years". On October 6, 1995 the Division of Epidemiology completed their review of the risk assessment methodology for this site and recommended that this variance be granted for 13 Goodwill Industries of the Southern Piedmont. Upon your concurrence with our recommendation, the Groundwater Section will proceed with the preparation of the required public notice and hearing. Upon completing of the requirements of 15A NCAC 2L .0113(d - f), with a recommendation to grant this variance from the Environmental Management Commission Groundwater Committee, this request will proceed to the Environmental Management Commission for final action in 15A NCAC 2L .0113(g). If there are any questions regarding this matter or if any additional information is needed, please let me know.

David Hance 1 DIVISION OF ENVIRONMENTAL MANAGEMENT GROUNDWATER SECTION January 12, 1996 MEMORANDUM To: From: Subject: Preston Howard Arthur Mouberry $ Request for Variance from 15A NCAC 2L .0202 and 15A NCAC 2L .01060) for a Site Owned by Goodwill Industries of the Southern Piedmont at 2122 Freedom Drive in Charlotte, North Carolina (Mecklenburg County) {Groundwater Incident Number 8094}. Goodwill Industries of the Southern Piedmont is a non-profit organization and serves as a vocational rehabilitation training center for the handicapped. A 2,000 gallon underground storage tank containing diesel fuel was removed from the site on November 21, 1990. Pursuant to title 15A NCAC 2L .Ol 13(c) variance applications are required to contain specific information in order to adequately review a request. Goodwill Industries variance application is contained in a report titled "Variance Request Incident Number 8094 Goodv,ill Industries of the Southern Piedmont. Inc. 2122 Freedom Drive Charlotte. North Carolina St':.~vffi Pro ject No. 1354-93-410". In addition, the Groundwater Section requested Goodwill lndustries provide clarifying information and editorial corrections to some of the information submitted in the report. The corrected information is shown in memoranda submitted on November 27th, December 4th, and December 7th of 1995. The information submitted by S&ME Incorporated on behalf of Goodwill Industries of the Southern Piedmont appears to meet the requirements of 15A NCAC 2L .0113(c) and is summarized as follows: Rule .0113 (c)(l): Resolution by the County or governing Board: Goodwill Industries of the Southern Piedmont has always been a private non-profit organization. No resolution is necessary. 1 Rule .Ol 13 (c)(2 ): A descri ption of past . existing or pro posed activities that would result in a dischar ge of contaminants into gr oundwater: Goodwill Industries of the Southern Piedmont is located inside the city limits of Charlotte, North Carolina at 2122 Freedom Drive (Parcel Number 071- 063-13). The report titled "Variance Re quest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410 contains the relevant information about this site. This facility is at the corner of Freedom Drive and · Berry Hill Road as shown in Figure 1 of Appendix in the report from S&ME Incorporated. The Goodwill Industries site consists of approximately 2.98 acres of land. Approximately one-half of the land area is covered by the building that houses Goodwill Industries. The former owner of this location was A.G. Boone Trucking Company. A 2,000 gallon underground storage tank containing diesel fuel was at the northwest corner of the building. This underground storage tank was removed on November 21, 1990 and the release was subsequently discovered upon tank closure. Goodwill Industries does not have any other underground storage tanks on this property. No other existing or potential sources of groundwater contamination were identified at this property by Goodwill Industries. Goodwill Industries of the Southern Piedmont and all adjacent properties are in an area with a mixture of commercial, industrial, and residential development. The tank closure report documented the removal of 240 tons of soil contaminated with diesel fuel. Analytical tests of soils within the excavation area did not indicate contamination below 21 feet from the ground surface. In August 1991 a Comprehensive Site Assessment was completed. The site assessment revealed a groundwater plume from a small area of contamination adjacent to the building. This area of contamination was at the northwest corner of Goodwill Industries near the companies loading dock and adjacent to the area where the diesel fuel pump had been located. The area of the plume was estimated to be approximately 60,000 square feet ( 400 feet long by 150 feet long). Monitoring indicated that the vertical extent of this plume was approximately 44 feet below the ground surface. The company estimated that approximately 5,924,952 gallons of groundwater had been contaminated by the release. On April 14, 1992 Goodwill Industries of the Southern Piedmont was informed that the Comprehensive Site Assessment had been completed to the satisfaction of the Division. Goodwill Industries submitted a Corrective Action Plan to address soil contamination on April 15, 1992. From September 6, 1992 through November 9, 1992 approximately 914 tons of soil was excavated and treated offsite adjacent to the loading dock area. The treatment method used for this soil was thermal incineration. A Corrective Action Plan or "Remedial Action Plan" was submitted to the Division on July 2, 1992 to cleanup groundwater 2 using pump-and-treat technology. Implementation of the Corrective Action Plan was approved by the Division on October 22, 1992. The Charlotte Mecklenburg Utility Department (CMUD) issued a permit to discharge treated water from the pump-and-treat groundwater remediation system into the nearby sanitary sewer. The Division of Environmental Management required Goodwill Industries to perfornt groundwater monitoring to determine the vertical and lateral extent of contamination at the site. On September 21, 1994 the company conducted comprehensive groundwater sampling at eight monitoring wells. The deepest of the monitoring wells is known as "DMW-3" and is 44 feet below the land surface. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. Only Benzene was found in the monitoring wells. The highest concentration found in a monitoring well in exceedence of the 15A NCAC 2L .0202 Groundwater Quality Standard for Benzene during this sampling event was 0.011 milligrams/Liter in Monitoring Well# 4. The Division also required Goodwill Industries to evaluate the eff ectiveii.ess of groundwater cleanup efforts by examining concentrations of substances recovery wells used as sumps to collect free product and dissolved hydrocarbons from the site. Samples were obtained from six recovery wells located beneath the building, parking lot, and loading dock areas. Groundwater samples were analyzed using US Environmental Protection Methods 602 and 625. The highest Benzene concentration in a recovery well showed 0.290 milligrams/Liter at Recovery Well# 5 beneath the building. Downgradient Monitoring Well# 7 located offsite southeast next to Freedom Drive did not show any concentrations above practical quantitation levels. Based on these results the Division of Environmental Management recommended the pump-and-treat system be turned off for a period of two months to determine if residual contaminants in the soils and subsurface would recontaminate the groundwater, if no treatment system were operating. In December 1994 groundwater monitoring was conducted at recovery wells and monitoring wells after the pump-and-treat system had been temporarily turned off. Four of the seven monitoring wells were sampled and all samples reported Benzene concentrations below quantitation limits. Concentrations of Benzene in all six recovery wells showed a significant decrease during this sampling event. Based on the results of the December 1994 monitoring, Goodwill Industries of the Southern Piedmont informed the Charlotte-Mecklenburg Utilities Department (CMUD) in January 1995 that it intendea to request a variance at this site. In Appendix III the January 12, 1995 memorandum from CMUD informed the responsible party that the existing permit to discharge treated groundwater into the sewer system would be extended beyond August 31, 1995 for an additional year, if the variance to terminate remediation is not granted by the Commission during the time. As shown in Appendix III, CMUD stated that the permit would be "extended" not "re-issued". On July 28, 1995 Goodwill Industries sent a variance request to the Chairman of the Environmental Management Commission pursuant to 15A NCAC 2L .0113(b). 3 Potential sources of groundwater contamination in the area are shown in Figure 2 in the report "Variance Re quest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Proiect No. 1354-93-410" and include the following: 1) A retail gasoline station presently owned by Servco located approximately 800 feet northwest of Goodwill Industries on Freedom Drive; 2) A fuel oil tank located approximately 250 feet to the northeast from Goodwill Industries. This fuel oil tank appears to be on property owned by Flemming Laboratories Incorporated; 3) An H 2SO 4 tank located approximately 250 feet to the northeast from Goodwill Industries. This chemical tank appears to be on property owned by Flemming Laboratories Incorporated; ; 4) An area containing what is described as "hazardous waste drums" approximately 250 to 300 feet to the east from Goodwill Industries. Figure # 2 appears to show that these drums are on property owned by Flemming Laboratories Incorporated. 5) Monitoring Wells owned by Flemming Laboratories Incorporated. These wells are located to the east and northeast of the Goodwill Industries site. 6) Berry Hill Road (a public roadway); 7) Freedom Drive (a public roadway); 8) A CSX Transportation Incorporated railroad line that is to the northeast and east of Goodwill Industries. The former owner of this line was the Piedmont and Northern Railroad Company; 9) A sewer line that is within of few feet of the southwest property line of Goodwill industries. This sewer runs from northwest to southeast parallel to the Goodwill Industries property line; 10) A storm drain line that is within of few feet of the southwest property line of Goodwill industries. This storm drain runs from northwest to southeast parallel to the Goodwill Industries property line; and 4 11) Numerous other storm drain lines and sewer lines that are in the general area. The property for which the variance is requested is entirely owned by Goodwill Industries of the Southern Piedmont. The groundwater that was impacted by the release is located beneath the building and the parking lot area. A fence is located at the northeast side of the building. Access to impacted groundwater at the site by workers, visitors, and unlawful intruders is under the control of the responsible party. Rule .Ol 13 (c)(3): Description of the pro posed area for which the variance is re quested: This variance is for an area entirely within the property boundaries of the Goodwill Industries of the Southern Piedmont. Maps of this area are shown in Figure 3 and Appendix Il of the report titled "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Proiect No. 1354-93-410". The contaminated area is in the form of an ellipse with it's longitudinal axis from northwest to southeast. The southeastern side of this ellipse is within a few feet of the storm drain line and sewer line that runs alongside Freedom Drive. More specifically the area for which the variance is requested is bounded to the north by the property line with Suburban Propane Company. This area laterally extends to the northeast toward the Suburban Propane Company property line, running beneath the Goodwill Industries Building, but does not extend as far as Monitoring Well# 6. The lateral area extends southeast toward property owned by D.L. Appliance Company but not as far as Monitoring Well # 7. The southwestern boundary of this area is at the property line that runs parallel with Freedom Drive. The western extent of this area is beneath the building and does not go as far as the position of Monitoring Well# 1. The extent of the northwest boundary includes part of the asphalt parking lot but does not go beyond the site where the diesel underground storage tank pump island once existed. The lateral extent of this plume stops before it reaches Monitoring Well# 2. - The concentration of contaminants in groundwater is primarily influenced by the direction and rate of groundwater flow. Goodwill Industries ass~rts that groundwater flow from the site travels toward a tributary of Stewart Creek approximately 700 feet to the southeast. This creek discharges into the Catawba River. The groundwater flow rate was obtained from information in the Comprehensive Site Assessment (CSA). Based on information in the CSA, Goodwill Industries of the Southern Piedmont asserts that groundwater in the area flows in a southeast direction. The 1994 groundwater monitoring results 5 from recovery wells beneath the building indicated that the contaminant plume is moving in a southeasterly direction toward Freedom Drive. The estimated groundwater flow velocity in the subsurface is approximately 11 feet/year. The company asserts that at this rate of groundwater movement the plume of petroleum hydrocarbon contamination will enter Stewart Creek in approximately 63 years~ assuming no natural degradation or attenuation of the plume occurs (See page 9 of the report). Page 3 of the report states that the company does not believe that any natural geologic structures exist in the subsurface beneath the site that would have the effect of creating an impermeable boundary to groundwater movement. Goodwill Industries believes that the depth to bedrock beneath the site is between 50 and 100 feet. No other properties owned by Goodwill Industries of the Southern Piedmont or properties owned by other persons are being included in this application for variance. (refer to Appendix Il of the report). Rule .0113 {c){4): Supp orting information to establish that the variance will not endanger the public health and safe ty ... : The part of the variance concerning Groundwater Quality Standards shown in 15A NCAC 2L. 0202 has been requested for Benzene, Ethylbenzene, Toluene, Xylene(-o,-m, and p), Naphthalene, Methyl Tert-Butyl Ether (MTBE), Dimethyl Phthalate, and 1,2-Dichlorobenzene. In order to assess health impacts from this site, monitoring wells were sampled at this site to assess the extent of contamination and concentration levels of substances. Concentrations of substances in recovery wells were also examine to determine the effectiveness of the pump and treat system at removing these chemicals. Groundwater monitoring data from Goodwill Industries of the Southern Piedmont indicates that this site does not pose a hazard to the public. Sampling and analysis has been conducted since May 8, 1991 at monitoring wells and recovery wells. Three sampling events occurred in March, September, December of 1994 and the last sampling and analysis was done on April 13, 1995. USEP A Method 602 and Method 625 were the analytical methods used for samples collected at the Goodwill Industries site. USEP A Method 602 is used to assess the concentration levels of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE. USEP A Method 625 is used to examine the concentrations of phthalate compounds, 1,2-Dichlorobenzene, Base/Neutral Extractables, and Naphthalene. The highest concentration of any substance found at this site was 0.590 milligrams per liter (mg/L) or 590 micrograms per liter (ug/L) of Dimethyl Phthalate in Recovery Well# 5. The Groundwater Quality Standard for this substance is zero pursuant to 15A NCAC 2L .0202(c). The lateral extent of this reported contamination is shown in Figure 4 of Appendix Il. Dimethyl Phthalate was not detected in any other recovery wells or in monitoring wells during this sampling event. Analysis of subsequent groundwater samples in 1994 and 1995 6 did not reveal Dimethyl Phthalate contamination in Recovery Well# 5, other recovery wells, or monitoring wells. In Table 2 of the report, the December 9, 1994 groundwater sampling was conducted at monitoring wells showed the concentrations of Benzene, Toluene, Ethylbenzene, Xylenes, and MTBE below their respective Groundwater Quality Standards in 15A NCAC 2L .0202. None of the monitoring wells showed concentrations of these substances above practical quantitation limits. The only wells that showed any concentration levels above Groundwater Quality Standards in 15A NCAC 2L .0202 from the USEP A Method 602 analysis were the recovery wells (RW #1 through RW # 6). The highest concentration in any single recovery well during this period was 0.071 milligrams per Liter (mg/L) or 71 micrograms per Liter (ug/L) at RW # 5. The analysis of samples using USEP A Method 625 did not reveal any concentrations of phthalate compounds, 1,2-Dichlorobenzene, or Naphthalene in the monitoring wells above the Groundwater Quality Standards in 15A NCAC 2L .0202. Base/Neutral extractable compounds, such as Anthracene, did not appear in concentrations above Groundwater Quality Standards or Interim Maximum Allowable Concentrations in any of these wells. Recovery Well# 5 showed Naphthalene at 0.062 mg/Lor 62 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). This recovery well is located in the center of the building which houses Goodwill Industries of the Southern Piedmont. It is important to note that this December 1994 sampling event had occurred some time after the pump-and-treat system had been temporarily turned off pursuant to the Division's instructions. No significant increase in concentrations of substances was observed as a result of the temporary cessation of pump-and-treat cleanup. On April 13, 1995 Goodwill Industries conducted a routine sampling of monitoring and recovery wells at the site. Table 2 shows results from USEP A Method 602 analysis. Three monitoring wells (MW # 3, DMW # 3, and MW # 4 had concentrations of Benzene above the Groundwater Quality Standard of 0.001 mg/L (1 ug/L). Monitoring Well# 4 had the highest concentration of Benzene at 0.004 mg/Lor 4 ug/L. Recovery Wells #1 through# 6 showed levels of Benzene above the Groundwater Quality Standard established by 15A NCAC 2L .0202. USEP A Method 625 analysis did not reveal any chemicals in monitoring wells above practical quantitation limits. Table 2 shows that Naphthalene continues to be present in Recovery Well# 5 at a concentration above the standard in 15A NCAC 2L .0202. Naphthalene was found in this welf"at 0.029 ing/L or 29 ug/L. The Groundwater Quality Standard for Naphthalene is 0.021 mg/L (21 ug/L). No other recovery wells have shown any constituents in exceedence of the standards contained in 15A NCAC 2L .0202 as a result of analysis using USEP A Method 625. Goodwill Industries of the Southern Piedmont has attempted to define the vertical extent of groundwater contamination beneath the site. The deepest well (DMW # 3) is 44 feet below the ground surface. Groundwater sampling and analysis was conducted using USEP A Method 602 and Method 625 at three 7 separate times in 1994 as shown in Table# 2. The analysis of the September 21, 1994 sampling event for DMW ·#3 showed a concentration of Benzene at 0.003 milligrams per liter. This level is in exceedence of the Groundwater Quality Standard of 0.001 milligrams per liter for this substance in 15A NCAC 2L .0202. The analysis of all other samples taken from this well in 1994 did not reveal any other chemical constituent from the petroleum release. A semi-annual sample was taken on April 13, 1995 at the monitoring well DMW # 3 and showed a Benzene concentration at 0.002 mg/L or 2 ug/L. No other substances normally associated with a release of diesel fuel were found in this monitoring well during the April 1995 sampling. (see Table 2 of the report). Page 8 of the report states that the downgradient recovery well (RW # 6) has not shown " ... any EPA Method 625 compounds and only 28 ug/1 of benzene ... ". Analysis of samples from the downgradient monitoring well MW # 7 has not shown any substances as a result of using USEP A Method 602 or Method 625. Based on the groundwater flow velocity of 11 feet per year from the site assessment, the company estimates that the time it will take the petrochemical plume to reach monitoring well # 7 is 4.5 years. Goodwill Industries believes that it will take a ·total of 10 years for the substances to reach the downgradient property boundary. These estimates are based on conservative assumptions that the plume will not be impacted by natural remedial processes and attenuation effects within the subsurface. It is not anticipated that rainfall events will significantly impact the movement of contaminants offsite. The area where groundwater monitoring results showed concentrations of Benzene, Naphthalene, and Dimethyl Phthalate above the standards is beneath the building that houses Goodwill Industries of the Southern Piedmont. The area outside this structure is covered by an asphalt driveway and parking area. No sources of drinking water from water wells or surface water are known to exist within a 1/2 mile radius of the Goodwill Industries of the Southern Piedmont. The requirements for variance applications in 15A NCAC 2L .0113(c)(4) specify that locations of drinking water wells and other water supply sources that are within one-half mile of the site must be shown on a map. The report from Goodwill Industries states that there are no drinking water wells within one-half mile of the site for which the variance has been requested. The December 7, 1995 memorandum referencing "Private Drinking Water Information" shows that there are no drinking water supply intakes at surface water bodies located within a 1/2 mile radius of the site. Drinking water for the City of Charlotte is obtained from Mountain Island Lake on the Catawba River five miles north-northwest of the site. All downgradient properties are supplied drinking water from the City of Charlotte. There are approximately six groundwater monitoring wells near the railroad tracks and Flemming 8 Laboratories Incorporated. These are to the northeast of the Goodwill Industries and are cross-gradient from the site. It appears unlikely that the presence of these wells would result in the movement of petroleum contamination from Goodwill Industries into groundwater. It is highly improbable that public water supply lines will be impacted by this variance. The nearest water supply lines are a 20 inch line that runs parallel on Freedom Drive and an eight inch ~upply line that runs along Berry Hill Road. The Groundwater Section contacted the Administration Division at the Charlotte- Mecklenburg Utility Department (704-399-2551) and was informed that the average ·depth of these water lines from the ground surface is four feet. Groundwater contamination beneath Goodwill Industries is too deep within the subsurface -to impact these lines. Rule .01 l3 (c)(5): Supp orting information to establish that requirements of the rule cannot be achieved by providing best available technolo gy economically reasonable: The part of the request that concerns variance to Corrective Action in ISA NCAC 2L .01060) will allow Goodwill Industries of the Southern Piedmont to discontinue Corrective Action at this site. Goodwill Industries of the Southern Piedmont has submitted supporting information in the report and other documents demonstrating that the continued application of BAT will not result in significant long term: remediation of the site to the Groundwater Quality Standards, contained in ISA NCAC 2L .0202. The is due to the high probability that continued remediation activities at the site will not significantly reduce contaminant levels below Groundwater Quality Standards in ISA NCAC 2L .0202. Since discovery of the release on November 21, 1990 the Goodwill Industries of the Southern Piedmont has disposed of a total of 1154 tons of diesel fuel contaminated soil. Goodwill Industries of the Southern Piedmont has treated approximately 2,108,185 gallons of groundwater to comply with the cleanup requirements of the Corrective Action Plan that was approved on October 22, 1992. Page 11 of the report titled "Variance Req uest Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Pro ject No. 1354-93-410" states that a total of $371,896 has been expended to cleanup this site. Goodwill Industries of the Southern Piedmont has incurred $77,122 of this lotal in the form of State Trust Fund deductibles and non-reimbursed items. Concentrations of substances in the groundwater have not been significantly reduced over the last year as shown in Table 2 of the report. Monitoring wells have shown insignificant reductions in Benzene using pump-and treat technology. Significant reductions in the concentrations of Naphthalene and Benzene have not been observed in recovery wells. It is also important to note that when the operation of the pump-and-treat groundwater remediation system was temporarily interrupted groundwater monitoring data indicated no increase 9 in the concentration of any constituent. In order to demonstrate that the requirements of the rule cannot be achieved using best available technology, Title 15A NCAC 2L .0113(c)(5) requires that specific technology considered be identified, the costs of implementing the technology be shown, and the impacts of the costs on the applicant be provided. Goodwill.Industries of the Southern Piedmont has considered the use of air sparging with vapor extraction as an alternate technology to the pump-and-treat groundwater remediation system. The company does not believe this technology is practical to meet the requirements of 15A NCAC 2L .0113(c)(5). In order to meet EHNR air quality standards, an air sparging system would need to be used in conjunction with vapor extraction to prevent fugitive vapors from spreading into the environment. The company asserts that two air sparging wells would need to be located inside the building in order to have an effective remediation system. The use of vapor extraction at the Goodwill Industries site would necessitate additional measures to protect workers from harmful concentrations of substances inside the building. The costs required to continually control vapor flow within the plant and the potential risk to workers offsets any inherent benefits of this cleanup method. Pursuant to the requirements of 15A NCAC 2L .0113(c)(5), the company does not believe that air sparging with vapor extraction an "economically reasonable" technology for this site. The Goodwill Industries of the Southern Piedmont has furnished cost information for an air sparging system with vapor extraction in Table 3 of the report "Variance Request Incident Number 8094 Goodwill Industries of the Southern Piedmont, Inc. 2122 Freedom Drive Charlotte, North Carolina S&ME Project No. 1354-93-410". This information is summarized as follows: Technology Air Sparging System Soil Vapor Extraction System Piping & Underground Utilities Permitting, Project Management, On-Site Supervision Plus Operation and Maintenance for One-Year Total Cost ($) $21,000 $17,600 $23,0'00 $38,400 Estimated Total Cost= $100,000 10 .. Goodwill Industries -has examined the potential effectiveness of .enhanced in-situ bioremediation technology for cleaning up the remaining contamination at this site. Enhanced in-situ bioremediation involves the introduction of nutrients and oxygen into groundwater. The company does not believe that this technology is the "best available technology economically reasonable" as specified in ISA NCAC 2L .0113(c)(5). If enhanced in-situ bioremediation was selected as the cleanup method for the Goodwill Industries site it would involve the use of injection wells to introduce nutrient substances into the subsurface that would assist in biodegradation. In order to permit injection wells under the current rules in ISA NCAC 2C .0200 they would have to permitted as Type SX (Other Wells). On page 2 of a December 4, 1995 memorandum the company's environmental consultant stated that permitting of injection wells for enhanced in-situ bioremediation would require the company to conduct extensive groundwater modeling studies and geochemical modeling. In addition, a site specific design for the injection well field would need to be developed prior to obtaining a permit. In addition, a corrective action plan using in-situ bioremediation would also need to be reviewed under the criteria in ISA NCAC 2L .0106(1). This rule requires a demonstration be made to the Director of the Division of Environmental Management that the site meets the criteria of ISA NCAC 2L .0106(1) so that the health, safety, and welfare of the public would not be impacted by allowing natural remedial processes to cleanup the site. In a November 27, 1995 letter Goodwill Industries states that the investigative work required to submit this corrective action plan would involve lengthy studies of the geochemical properties of the site, flew properties of the contaminated matrix, and developing methods of measuring the contaminate concentration. A study of the feasibility of bioremediation would also need to be conducted to show that a corrective action plan under ISA NCAC 2L .0106(1) would effectively reduce contaminate concentrations to the level of the standards. The company believes that in order to determine the feasibility of in-situ enhanced bioremediation, an assessment of biologic processes in the soil would need to be examined and the toxicity of soi.is and sediments to these organisms would need to be assessed. Goodwill Industries believes that the costs of the investigative work to permit injection wells and develop a corrective action plan would likely exceed the costs of implementing a corrective action plan relying on air sparging technology. Rule .Ol 13(c)(6): Supporting information to establish that compliance would produce serious financial hardship on the applicant: In pages 10 through 12 of the report reveals that Goodwill Industries of the Southern Piedmont has demonstrated that continued application of best available technology to this site would be a prohibitively expensive method of 11 remediating groundwater contamination. Some of the plumbing for the pump- and-treat cleanup system is located in various parts of the building. Continual reliance on the pump-and-treat system will mean that Goodwill Industries will not be able to utilize this additional space for offices. Based on the previous installation of the pump-and-treat groundwater remediation system, Goodwill Industries foresees the use of an air sparging system with vapor recovery to cleanup the site resulting in a major disruption of business operations at Goodwill Industries. The floor space within the Goodwill Industries site would need major renovations in order to install this type of system. The loading dock area would need to be closed during construction and installation of the system causing the loss of unrecoverable revenues to the company.· Continued operation of the pump-and-treat system may require additional expenses on the part of Goodwill Industries. On January 12, 1995 the Charlotte- Mecklenburg Utility Department (CMUD) gave Goodwill Industries an "extension" to continue discharging treated effluent from the pump-and-treat groundwater remediation system into the city's sewer system until August 31, 1996. No indication was given by CMUD as to future extensions or reissuance of a permit for the discharge beyond one year. If Goodwill Industries continues to conduct corrective action that necessitates the discharge of treated effluent and the CMUD does not continue permitting the discharge into the sewer system, the company will need to pursue a separate discharge for this system. Such a discharge may require the construction of piping and pumping devices to the nearest discharge point at a surface water body. The company reports that the nearest drainage feature is Stewart Creek located approximately 700 feet downgradient from the site. In addition, this discharge would need to meet the requirements of state NPDES water quality rules in 15A NCAC 2B. Permitting and construction of a new discharge line for the present pump-and-treat system would require the additional expense of funds by the responsible party. Assuming that the option of a discharge to Stewart Creek is the most cost effective of other alternatives and the site remains eligible for state trust fund reimbursement, the responsible party may receive reimbursement through the trust fund for "reasonable and necessary costs" during permitting and construction of the discharge line. The company believes that there is immense uncertainty that best available technology will remediate the groundwaters at this site to standards within a foreseeable period of time. Goodwill Industries of the Southern Piedmont asserts that allowing natural remedial processes to degrade and attenuate substances found at the site will be no less effective a method than using technologic methods discussed and will not entail the same burdensome costs upon the company. 12 Rule .0113 (c)(7 ): Supp orting information that compliance would produce serious financial hardship without equal or greater public benefit: The company has submitted information in the request demonstrating that the environment, safety and public health would not be impacted by this variance. If air sparging with vapor recovery is used as an alternate cleanup method, it will necessitate the continual closing of this facility until the new system is constructed, installed, tested, and approved. The community that relies on vocational training provided by Goodwill Industries of the Southern Piedmont will not have access these resources. The Groundwater Section believes that the public will not benefit from compelling the Goodwill Industries of the Southern Piedmont to remediate this site using pump-and-treat technology or alternatives discussed. Rule .0l 13 (c)(8): "A cop y of any Special Order ... ": No Special Order by Consent has been issued for this site. Rule .0l 13 (c)(9): "A list of names and addresses of pro pertv owners ... ": The property owners within the proposed area of the variance are shown in Table# 1 that was revised on November 17, 1995 in a letter and includes the Dixie Electric Company, the D&L Appliance Company, the Suburban Propane Gas Corporation, the North Carolina Department of Transportation, CSX Railroad Incorporated, the E.F. Lombardi Company, and Goodwill Industries of the Southern Piedmont. Title 15A NCAC 2L .0113(e)(E) requires that notification of a public hearing on this variance be given to these adjacent property owners "at least 30 days prior to the date of the hearing". It is the recommendation of the Groundwater Section tlfat the subject variance request to Corrective Action requirements of 15A NCAC 2L .01060) and Groundwater Quality Standards contained in 15A NCAC 2L .0202 proceed to public notice in accordance with 15A NCAC 2L .0l 13(e). Please note that the Mooresville Re gional Office has recommended that this variance be granted upon the condition that an additional monitoring well be installed. It has further been recommended that this well be installed south of the well identified as Recovery Well# 5 (RW #5 ) and that "selected wells be sam pled semi-annually for several years". On October 6, 1995 the Division of Epidemiology completed their review of the risk assessment methodology for this site and recommended that this variance be granted for 13 Goodwill Industries of the Southern Piedmont. Upon your concurrence with our recommendation, the Groundwater Section will proceed with the preparation of the required public notice and hearing. Upon completing of the requirements of 15A NCAC 2L .0113(d - f), with a recommendation to grant this variance from the Environmental Management Commission Groundwater Committee, this request will proceed to the Environmental Management Commission for final action in 15A NCAC 2L .0113(g). If there are any questions regarding this matter or if any additional information is needed, please let me know.

The CSA results were reviewed by the NCDEHNR and the report approved. Subsequently, A Corrective Action Plan (CAP) to cleanup the site was prepared and approved by the NCDEHNR. Installation of a private well in Mecklenburg County does not require a permit. Therefore, the Mecklenburg County Health Department does not have any records documenting the location of private drinking wells. Drinking water for the city is obtained from Mountain Island Lake, which is located on the Catawba River approximately five miles north- northwest of the site.

The map shows properties within a 1,000 foot to 1,500 foot radius of Goodwill Industries. Each of the numbers on the map indicate that a property is supplied water by CMUD. Most importantly, the map indicates that properties downgradient of the site are supplied water by CMUD. There is a groundwater incident site (NCDEHNR Incident No, 8982) known as Biltmore Dairy Farms located approximately one-quarter mile southeast of Goodwill Industries facility. The CSA for this site was prepared by Westinghouse Environmental and Geotechnical Services, Inc. (WEGS). Similarly, CSA results for this site indicate that there were no private drinking water wells found within a quarter-mile radius of the Biltmore site.

Groundwater Incident~ 8094 Upon review of the July 1995 variance request and the Groundwater Incident file for the subject site, the MRO recommends approval of the variance with the following comments: 1. The groundwater contaminant plume does not appear to extend past the boundaries of the Goodwill Industries site. 2. No potable wells exist within a\ mile radius of the subject site. 3. The MRO agrees that the implementation of an air sparging and soil vapor extraction system is neither cost effective nor practical since the bulk of the contaminant plume is located under the Goodwill Industries building and activation of this type of remediation system could result in vapor hazards within the facility. If a variance is granted for the subject site, we would recommend that an additional monitor well be installed south of recovery well RW-5 and that selected wells be sampled semi- annually for several years. · Attached to this memo is the only known copy of the variance request. · If you should have· any questions, I can be reached at (704) 663-1699, ext. 236.
