UST Information Tank No. Date Installed Size (gallons) Tank Dimension Last Contents Previous Contents (if any) UST-2 Unknown 10,000 26’5” x 8’ Heating Oil Unknown UST-A Unknown 10,000 16’9” x 10’ Diesel Unknown E. Site Characteristics 1.Describe any past releases at this site: Several past releases have been associated with the operations of several USTs located at the site with two incidents identified on the Leaking Underground Storage Tank (LUST) database. ECS reviewed the NCDEQ file for these incidents and are described below. Incident No. 14620 indicated that one gasoline UST (UST-3) that was reportedly 150-gallons and one 275- gallon heating oil UST (UST-4) were removed in 1995. At that same time, one 2,000-gallon heating oil UST (UST-6) and one 275-gallon heating oil UST (UST-5) were closed in place at the site. Soil samples were not 700 South Holden Road Greensboro, Guilford County, NC 27407 3 collected from beneath the two 275-gallon heating oil USTs and the 2,000-gallon gasoline UST during removal or closure. One soil sample was collected from beneath the 150-gallon gasoline UST during removal. Laboratory analysis detected 16,512 ppm (parts per million) total petroleum hydrocarbons (TPH) in a sample collected from beneath the 150-gallon gasoline UST. A Comprehensive Site Assessment (CSA) was performed in the vicinity of the 150-gallon gasoline UST. During the assessment, one groundwater monitoring well was installed in the vicinity of the UST and four groundwater monitoring wells were installed in proximity to the UST. Groundwater samples were collected from the monitoring wells and analyzed for petroleum constituents. Petroleum constituents were not detected above North Carolina 2L Ground Water Quality Standards (NC2LGWQS) in the four wells located in proximity to the former UST. However, several petroleum constituents were detected above NC2LGWQS in the sample collected from the monitoring well located at the former UST. The CSA indicates that the groundwater contamination is confined to areas near the UST. Groundwater flow direction in the area of the release was determined to be to the northwest. Incident No. 19003 indicated that assessment took place during the removal of a 30,000-gallon heating oil UST (UST-1) in 1998. During the removal, four soil samples were collected from beneath the UST and one sample was collected from beneath the product line and analyzed for petroleum constituents. Several petroleum constituents were detected above Maximum Soil Contamination Concentrations (MSCC) Soil-to- Groundwater Standards in the sample collected from beneath the product piping. A Phase I Limited Site Assessment was conducted in the vicinity of the 30,000-gallon heating oil UST. A report issued January 29, 1999 indicated that one groundwater monitoring well was constructed in the vicinity of the release and a groundwater sample was collected. The groundwater sample was analyzed for petroleum constituents. No petroleum constituents were detected above NC2LGWQS. ECS issued a Report of Environmental Assessment Services for this subject property in June 2008 (ECS Project number 09-15656A). ECS was contracted to assess whether an undocumented release had occurred from the three former USTs, and the existing UST that had not been assessed. The assessment was conducted to assess the current concentrations in the soil and groundwater in the vicinity of the USTs. Soil samples were collected from the vicinity of the former 150-gallon UST, the 30,000-gallon UST, the 2,000- gallon UST, a previously closed in place 275-gallon UST and the existing 10,000-gallon UST (UST-2). Laboratory analysis of soil samples collected from the former 2,000-gallon UST and the 275-gallon UST did not identify petroleum-related compounds. ECS recommended that a No Further Action letter (NFA) be issued for these areas. Petroleum-related compounds were identified above action levels in soil samples collected from the vicinity of the 10,000-gallon UST. Laboratory analysis of soil samples collected from the vicinity of the 30,000-gallon UST identified petroleum-related compounds above their respective Soil-to-Groundwater and Residential MSCCs. Groundwater samples were collected from the vicinity of the 30,000-gallon UST and 10,000-gallon UST. Lead was identified in one groundwater sample. Based on the lack of presence of other petroleum-related compounds in the groundwater samples, it was ECS' opinion that the concentration of lead is naturally occurring and related to a turbid sample. Due to the lack of additional petroleum-related compounds in the vicinity of the former 150-gallon UST, ECS recommended that an NFA be issued in regards to the 150-gallon UST. 700 South Holden Road Greensboro, Guilford County, NC 27407 4 ECS recommended that a NFA be issued for the site in regard to the 30,000-gallon UST and a Notice of Residual Petroleum (NORP) be completed for the soil in the vicinity of the 30,000-gallon UST. The NORP was recorded on November 18, 2009. The NORP indicated petroleum-contaminated soil is present on the subject property and shall not be excavated or disturbed within three feet of the delineated area. An NFA was issued for the Incident No. 19003 on November 9, 2009. An NFA was issued for Incident No. 14620 on October 22, 2018. 2. Is the facility active or inactive at this time? The approximate 39.78-acre subject property is occupied by the Whitestone Masonic and Eastern Star Community. The subject property contains assisted living buildings, a care and wellness center, a boiler building, dining building, a chapel, maintenance building, single-occupancy homes, cottages, a cemetery, landscaped areas and asphalt roads and parking areas. The buildings are heated with natural gas, with the exception of the Latham building, which is heated with steam produced in the boiler building. Water and sanitary sewer services are provided by the City of Greensboro. 3.Describe surrounding property use (for example, residential, commercial, farming, etc.): The site is located at 700 South Holden Road, Greensboro, Guilford County, North Carolina. The subject property is located in a commercial/residential area of Greensboro, North Carolina. The subject property is bound on the north by Wendover Avenue, followed by residential properties; on the east by South Holden Road, followed by residential properties and a multi-unit retail building and a Dunkin Donuts; on the south by an unnamed automobile repair facility, wooded land, single-family residence, Gay Terrace, Iglesia Pentescostes, Crazy Tires, and Spring Garden Street, followed by Bain Oil, Phoenix Collision Repair, and Ray Self Storage; and, on the west by Coapman Street, followed by residential properties and Wendover Ridge Apartments. A portion of the Greensboro 7.5-minute NC quadrangle map has been included as Figure 1 and details the site location and topography. 4.Describe site geology/hydrogeology: Site geology has been characterized through observations of the two UST excavation sidewalls and bottom as well as the sidewalls and bottom of the additional over-excavated area to the northwest of the two UST basins. Based upon these observations, the site geology consisted of a reddish-brown silty clay from just below ground surface (bgs) to the excavation’s maximum depth of 20-feet bgs. Neither bedrock nor groundwater was encountered or observed in the UST excavation to its maximum dug depth of 20-feet bgs. II.Closure Procedures A. Describe preparations for closure including the steps taken to notify authorities, permits obtained and the steps taken to clean and purge the tanks: - On March 19, 2021, ECS conducted abandonment activities at monitoring wells MW-1-10K, MW-1, and four additional monitoring wells located near MW-1. The additional monitoring wells were identified as MW-2 through MW-5 by ECS personnel prior to conducting well abandonment activities. Upon arrival, MW-1-10K was observed to have been damaged. ECS attempted to measure the depth of MW-1-10K 700 South Holden Road Greensboro, Guilford County, NC 27407 5 but encountered refusal at approximately 8 feet below top of casing (ft btoc). After further inspection, monitoring well MW-1-10K was presumed damaged and a groundwater sample was unable to be collected. The combined 2-inch diameter monitoring well footage totaled 178 ft btoc. The monitoring well abandonment records (Form GW-30) are included in Appendix A. Photo documentation depicting abandonment activities is included in Appendix B. - Prior to closure of the 10,000-gallon capacity heating oil UST, identified as UST-2, by removal, a GW/UST-3 Form was submitted to the Guilford County Department of Health and Human Services on April 20, 2021. A copy of the GW-UST-3 Form has been included in Appendix C. - A total of 1,800-gallons of residual petroleum/ rinse water and 273-gallons of sludge were evacuated from the two USTs in efforts to prepare the two USTs for removal on June 3, 2021 and June 9, 2021, respectively. A copy of the liquid disposal manifests has been included in Appendix D. - Buckeye Elm notified the City of Greensboro Fire Marshall’s Office of the UST removal and acquired necessary permits. The two 10,000-gallon USTs (UST-2 and UST-A) were removed upon the Fire Marshall's inspection and approval on April 2, 2019. - A UST-2A and UST-2B Form, Site Investigation Report for Permanent Closure or Change-in-Service form for both the registered tank and unregistered tank, were completed and emailed to the NCDEQ Central office and the Guilford County Department of Health and Human Services on July 22, 2021. A copy of the UST-2A has been included in Appendix E. - Two 10,000-gallon capacity USTs respectively containing heating oil and diesel and approximately 20- feet of associated product piping were removed as shown in Figure 2. The two 10,000-gallon capacity USTs were measured to be 26’5” long by 8’ in diameter (UST-2), and 16’9” long by 10’ in diameter (UST- A). Disposal manifests for the removed USTs are included in Appendix D. B. Note the amount of residual material pumped from the tank(s): - The two 10,000-gallon capacity USTs contained measurable fluids prior to removal on June 3, 2021 and June 9, 2021, respectively. Buckeye Elm contracted with EVO to remove the residual materials. A cumulative reported total of 1,800-gallons of petroleum impacted water and a total of 273-gallons of sludge was measured on EVO’s vacuum truck on June 3, 2021 and June 8, 2021, respectively, prior to mobilization offsite for disposal. A copy of the liquid disposal manifest has been included in Appendix D. C. Describe the storage, handling, and disposal of the residual material: - The residual material was transported by EVO to their facility in Winston-Salem, North Carolina for disposal. A copy of the liquid disposal manifests has been included in Appendix D. D. Excavation 1. Describe excavation procedures noting the condition of the soils and the dimensions of the excavation in relation to the tanks, piping and/or pumps: One 10,000-gallon capacity heating oil UST (UST-2) measuring 26’5” long by 8’ in diameter along 20 linear feet of product line piping was removed on June 3, 2021. Additionally, one 10,000-gallon capacity “orphan” diesel fuel UST (UST-A) measuring 16’9” long by 10’ wide was removed on June 9,2021. The locations of the 700 South Holden Road Greensboro, Guilford County, NC 27407 6 removed USTs and product piping are shown on the Site Map included as Figure 2. Excavation Procedures: 1.) The soils overlying UST-2 in the area of the fill port were noted to be stained from apparent spillage/overfilling. This soil was excavated and temporarily stockpiled onto 10-mil thick poly sheeting for future disposal. Additional apparent impacted soil was excavated from this area until it was determined via field screening that the remaining soils no longer appeared to contained petroleum impacts. 2.) Additional clean overburden soils were then excavated and stockpiled adjacent to the two UST basin’s western sidewall until both USTs were fully uncovered and removed from their respective basins. Upon removal, the USTs appeared to be in good condition with no corrosion holes observed. See photo-documentation included in Appendix B. No evidence of a release was noted from either of the two USTs upon their removal. 3.) Once removed from the basin, the two tanks were temporarily set upon the impacted overburden soil stockpile. The tanks were then loaded onto a flat-bed trailer truck for transportation to the recycling facility. UST-2 was transported offsite on June 3, 2021 following its closure by removal and UST-A was transported offsite on June 9, 2021 following its closure by removal. The Bill of Lading for the transport of the closed USTs has been included in Appendix D. 4.) Once the two 10,000-gallon USTs had been removed, over-excavation of impacted soils associated with the former 30,000-gallon UST (UST-1) was conducted. These soils were load directly into a stand-by dump truck following removal from the UST basin for transportation offsite. 5.) Over-excavation activities occurred throughout the previously delineated impacted soils associated with the former 30,000-gallon UST release located to the northeast of the removed 10,000-gallon USTs. The overall horizontal extent of the over-excavation has also been illustrated on Figure 2 and its vertical extent was terminated at depth of approximately 20 feet bgs. 2. Note the depth of tank burial(s) (from land surface to top of tank): The first 10,000-gallon heating oil UST-2 was buried approximately 6 feet below ground surface and the second 10,000-gallon “orphan” diesel UST-A was buried approximately 4 feet below ground surface. 3. Quantity of soil removed: A total of approximately 683.33 tons of impacted soil was removed for disposal on June 3, 2021 through June 4, 2021 and June 8, 2021, respectively. The removed impacted soil was transported by EVO to their disposal facility located in Winston-Salem, NC. Certified weight tickets and disposal manifests have been included in Appendix F. 4. Describe soil type(s): Soil surrounding the UST was characterized through observations of the UST excavation sidewalls and bottom. Based upon these observations, the surrounding soil consisted of a reddish-brown silty clay from just below land surface to the excavation's maximum termination depth of 20 feet bgs. Neither competent bedrock nor groundwater were encountered in the either of the two UST basins or the over excavated area 700 South Holden Road Greensboro, Guilford County, NC 27407 7 to a depth of 20 feet bgs. See Photo-documentation attached in Appendix B. 5. Type and source of backfill used: The excavation was backfilled with clean onsite materials and completed by the onsite grading contractor, Frank L. Blum Construction Company. E. Petroleum Hydrocarbon Impacted Soil 1. Describe how it was determined to what extent to excavate the soil: A flame ionization detector (FID) was used to determine the presence of volatile organic vapor concentrations in soils located near the fill port of the removed UST (UST-2) and soils associated with the former 30,000-gallon UST (UST-1) release. Additionally, apparent petroleum staining and odors of the soils in these locations were also used evaluate the extent of impacted soil. When these screening methods suggested that the petroleum-impacted soils had been removed, ECS recommended that excavation be terminated. The overall horizontal extent of the excavation has been illustrated on Figure 2 and its vertical extent was terminated at depth of approximately 20 feet bgs. 2. Describe method of temporary storage, sampling, and treatment/disposal of soil: Soils excavated for disposal from the fill port area were temporarily stockpiled on 10-mil thick poly sheeting. Over-excavated soils that were associated with the former 30,000-gallon UST were loaded directly into dump trucks for off-site disposal from June 3, 2021 through June 8, 2021, respectively. A total of approximately 683.33 tons of impacted soil were removed for disposal. That total included the temporary stockpiled fill port overburden and the over-excavated soil that was associated with the former 30,000- gallon UST-1. The impacted soils were transported to EVO’s disposal facility located in Winston-Salem, NC. Certified weight tickets and soil disposal manifests have been included in Appendix F. Seven (7) UST closure samples were collected from directly beneath each bottom of the two 10,000-gallon capacity USTs and the associated 20-feet of product line immediately following removal from their respective basins. Closure soil samples, identified as UST-1A through UST-1C, were collected immediately beneath the bottom of UST-2 at a depth of approximately 15-16 feet bgs and closure soil samples, identified as UST-2A and UST-2B, were collected immediately beneath the bottom of UST-A at a depth of approximately 14-15 feet bgs. The remaining closure samples, identified as L-1 and L-2, were collected directly beneath the 20-foot length of product line associated UST-2 at a depth of approximately 5-6 feet bgs. Each closure sample was submitted to the analytical laboratory for analyses of total petroleum hydrocarbons (TPH) gasoline range organics (GRO) and diesel range organics (DRO) by ultraviolet fluorescence (UVF) method. The closure soil samples was submitted to Red Labs, LLC (Red Labs), a North Carolina certified laboratory located in Wilmington, NC per the dates and times included on the chain-of- custody (COC) documentation. The Red Labs soil analytical laboratory report and COC has been included as Appendix G. Additionally, six (6) over-excavation soil samples were collected from the previously delineated impacted soils associated with the former 30,000-gallon UST release. Two over-excavation samples were collected from the base (B-1 and B-2) and four over-excavation samples were collected from the sidewalls (SW-1 through SW-4) of the excavated area as illustrated on Figure 2. B-1 and B-2 were collected along the centerline of the base excavation area at a depth of ranging from approximately 16 to 20 feet bgs and SW-1 through SW-4 were collected along the sidewalls of the excavation area at a depth of ranging from 700 South Holden Road Greensboro, Guilford County, NC 27407 8 approximately 16-20 feet bgs. Each over-excavation sample was submitted for analyses of volatile organic compounds (VOCs) by EPA Method 8260, semi-volatile organic compounds (SVOCs) by EPA Method 8270, and Volatile Petroleum Hydrocarbons (VPH) and Extractable Petroleum Hydrocarbons (EPH) by the Massachusetts Department of Environmental Protection (MADEP) methods. The over-excavation soil samples were submitted to Pace Analytical Services, LLC (Pace), a North Carolina certified laboratory located in Huntersville, NC per the dates and times included on the COC documentation. The Pace soil analytical laboratory report and COC has been included as Appendix G. III. Site Investigation A. Provide information on field screening and observations, include methods used to calibrate field screening instrument(s): Field screening was performed during soil excavation activities using a FID calibrated in accordance with manufacturer’s instructions from June 3, 2021 through June 9, 2021. Additionally, the soils were visually assessed for evidence of staining and evaluated for petroleum odors. FID measurements collected from the soils taken directly below the center of the UST basins and associated product piping ranged from 7.1 parts per million (ppm) to 21.6 ppm. Additionally, FID measurements collected from the soils taken from the former 30,000-gallon UST over-excavation area ranged from 9.7 ppm to 28.7 ppm. B. Describe soil sampling points and sampling procedures used, including: - Location of samples - Type of samples (from excavation, stockpiled soil, etc.) - Sample collection procedures (grab, split spoon, hand auger, etc.) - Depth of soil samples (below land surface) - Whether samples were taken from side or floor of an excavation - Sample identification and analyses Stockpile Soil Sampling One sample of the stockpiled soils was collected on June 3, 2021. The stockpile soil sample, identified as SP- 1, was collected from the overlying impacted soils surrounding the fill port of UST-2. The soil sample was submitted in laboratory supplied containers to be analyzed for TPH GRO and DRO by UVF method. UST Closure Soil Sampling A total of seven (7) soil samples were collected for UST closure purposes on June 3, 2021 and June 9, 2021, respectively, from the locations shown on Figure 2. Closure soil samples, identified as UST-1A through UST- 1C, were collected immediately beneath the bottom of UST-2 at a depth of approximately 15-16 feet bg. Additionally, closure soil samples, identified as UST-2A and UST-2B, were collected immediately beneath the bottom of UST-A at a depth of approximately 14-15 feet bgs. The remaining closure samples, identified as L- 1 and L-2, were collected directly beneath the 20-foot length of product line associated UST-2 at a depth of approximately 5-6 feet bgs. Each closure soil sample was submitted in laboratory supplied containers to be analyzed for TPH GRO and DRO by UVF method. 700 South Holden Road Greensboro, Guilford County, NC 27407 9 Over-Excavation Soil Sampling Excavation activities to remove the previously delineated impacted soils associated with the former 30,000- gallon UST release were initiated on June 4, 2021. The final excavation limits of the area associated with the 30,000-gallon UST were measured to be 25-feet long by 12-feet wide by 20-feet deep as shown on Figure 2. Following completion of over-excavation activities on June 8,2021, ECS collected six over-excavation soil samples. Two over-excavation samples were collected from the base (B-1 and B-2) and four over-excavation samples were collected from the sidewalls (SW-1 through SW-4) of the excavated area as illustrated on Figure 2. B-1 and B-2 were collected along the centerline of the base excavation area at a depth of ranging from approximately 16 to 20 feet bgs and SW-1 through SW-4 were collected along the sidewalls of the excavation area at a depth of ranging from approximately 16-20 feet bgs. Over-excavation soil samples were submitted in laboratory supplied containers to be analyzed for risk-based soil characteristics including VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and VPH and EPH by the MADEP methods. The post-excavation sample locations are illustrated on Figure 2. C.

Investigation results - Describe methods of analyses used (include U.S. EPA method number) - Describe analytical results for samples; discuss in relation to site specific cleanup level or action level, as appropriate Stockpile Soil Sample Quality One stockpile soil sample was collected on June 3, 2021. The stockpile soil sample, identified as SP-1, was collected from the overlying impacted soils surrounding the fill port of UST-2. The soil sample was submitted for laboratory analysis for TPH GRO and DRO using the UVF method. TPH GRO and DRO by UVF Analysis by UVF for soil sample SP-1 reported a GRO concentration of 1,780 milligrams per kilogram (mg/Kg), and DRO concentration of 11,892 mg/Kg. Both GRO and DRO concentrations were in excess of the NCDEQ Soil Action Levels of 50 mg/Kg and 100 mg/Kg for GRO and DRO, respectively. TPH GRO and DRO analytical results are presented in Table 1. Complete soil analytical laboratory reports with COC documentation have been included in Appendix G. UST Closure Soil Sample Quality A total of seven (7) closure soil samples were collected on June 3, 2021 and June 9, 2021, respectively. The samples, identified as UST-1A through UST-1C, were collected immediately beneath the bottom of UST-2 at a depth of approximately 15-16 feet bgs and closure soil samples, identified as UST-2A and UST-2B, were collected immediately beneath the bottom of UST-A at a depth of approximately 14-15 feet bgs. The remaining closure samples, identified as L-1 and L-2, were collected directly beneath the 20-foot length of product line associated UST-2 at a depth of approximately 5-6 feet bgs. Figure 2 illustrates the approximate soil sample locations. Each closure soil sample were submitted for laboratory analysis for TPH GRO and DRO using the UVF method. TPH GRO and DRO by UVF Analysis by UVF for each closure soil sample did not report GRO or DRO at a concentration above the NCDEQ Soil Action Levels of 50 mg/Kg and 100 mg/Kg for GRO and DRO, respectively. TPH GRO and DRO analytical results are presented in Table 1. Complete soil analytical laboratory reports with COC documentation have been included in Appendix G. Over-Excavation Soil Sample Quality – October 9, 2018 A total of six over-excavation soil samples were collected from the previously delineated impacted soils associated with the former 30,000-gallon UST release. Two over-excavation samples were collected from the base (B-1 and B-2) and four post-excavation samples were collected from the sidewalls (SW-1 through SW-4) of the excavated area as illustrated on Figure 4. Each of the over-excavation soil samples were submitted for analysis of VOCs, SVOCs, EPH) and VPH. 700 South Holden Road Greensboro, Guilford County, NC 27407 11 VOCs Analytical Results VOC analysis indicated several select targeted analytes to be above their respective laboratory reporting limits, however, the concentrations do not exceed their respective Soil to Groundwater Maximum Soil Contaminant Concentrations (MSCCs)or Residential MSCCs.

EPH and VPH Laboratory result so the EPS and VPH analysis indicated the following concentrations of method targeted petroleum hydrocarbon fractions in soil samples SW-1 and SW-2: Aromatic petroleum hydrocarbon fraction C9-C22 at 0.82 mg/Kg and at 1.6 mg/Kg respectively. Both concentrations are above the Soil to Groundwater MSCC, however, do not exceed the Residential MSCC. No further EPH or VPH petroleum hydrocarbon fractions were reported in excess of their respective Soil to Groundwater MSCCs or Residential MSCCs. A summary of the results are provided in Table 3. Complete laboratory reports with COC documentation have been included in Appendix G. IV. Conclusions and Recommendations Include probable sources of contamination, further investigation or remediation tasks, or whether no further action is required. Conclusions The two former 10,000-gallon capacity USTs and their contents were removed from the site on June 3, 2021 and June 9, 2021, respectively. There are no further known USTs remaining on the property. During the UST closure activities, the two USTs were observed to be in overall good condition with only rusting and pitting observed on each UST. Residual fluids were measured in each UST prior to removal and a recorded total of 1,800-gallons of petroleum impacted water and 273-gallons of sludge were evacuated from the USTs on June 3, 2021 and June 8, 2021, respectively. Following evacuation of the residual liquids, the two USTs were removed from their respective basins for disposal offsite. Soil over-excavation activities were performed horizontally towards the northwest of the two 10,000-gallon UST basins to a maximum excavation depth of 20-feet bgs. A total of approximately 683.33 tons of impacted soil were removed for disposal. That total included the temporary stockpiled fill port overburden and the over-excavated soil that was associated with the former 30,000-gallon UST-1 release. Over-excavation soil quality sampling subsequently indicated that impacted soils were successfully removed to below their 700 South Holden Road Greensboro, Guilford County, NC 27407 12 respective Residential MSCCs of the over-excavated area associated with the former 30,000-gallon UST-1 release. Recommendations ECS, on behalf of LCS Development, LLC, respectfully requests that return correspondence be made by the NCDEQ following review of this report. Based upon the closure and over-excavation sample analytical results collected from the two former UST basins and the over-excavation area associated with the former 30,000- gallon UST-1 release, ECS recommends No Further Action (NFA) for this UST Closure and rescinding the Notice of Residual Petroleum (NRP) placed on the property associated Incident No. 19003. However, due to the Soil-to-Groundwater exceedances, the collection of one groundwater quality sample in the vicinity of SW-1 and SW-2 may be determined necessary prior to obtaining a Letter of NFA.

Also send a copy to the Central Office in Raleigh. SEE MAP ON THE BACK OF THIS FORM FOR THE CENTRAL AND REGIONAL OFFICE ADDRESSES. STATE USE ONLY I.D. #_____________________ Date Received______________ INSTRUCTIONS (READ THIS FIRST) Complete and return a UST-3 form at least thirty (30) days prior to closure or change-in-service activities. If a Professional Engineer (P.E.) or a Licensed Geologist (L.G.) provides supervision for closure or change-in-service site assessment activities and signs and seals all closure reports then at least a five (5) working days’ notice is acceptable. Completed UST closure or change-in-service site assessment reports, along with a copy of the UST-2A and/or 2B forms, should be submitted to the appropriate Division of Waste Management (DWM) Regional Office within thirty (30) days following closure activities. The UST-2 form should also be submitted to the Central Office in Raleigh so that the status of the tanks may be changed to permanently closed and your tank fee account can be closed out. Note: Tank fees may be due for unregistered tanks. UST closure and change-in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site Checks, Tank Closure and Initial Response. The guidelines can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust. Note: To close tanks in place you must obtain prior approval from the DWM Regional office located in the region where the facility is located. You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the tank(s) will be taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed by a qualified company. Tanks disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment. If your tanks are disposed of improperly, you could be held responsible for the cleanup of any environmental damage that occurs. I. OWNERSHIP OF TANKS II.
