Cullman Avenue Sites
As part of real estate due diligence associated with Charlotte-Mecklenburg Storm Water Services, Flood Mitigation Program's purchase of properties along flood prone areas, ESP completed separate Phase I ESAs on three warehouse-type properties located along Cullman Avenue in the NoDa district of Charlotte, North Carolina.


FedEx Ground Distrubution Center
As part of the purchase of an operating FedEx ground distrubition facility located in Fort Mill, SC, ESP completed a Phase I ESA for Monmouth Real Estate. The approximate 18-acre site consisted of an operating 113,000-sq.ft. FedEx Ground Distribution Center located in an area consisting of commercial, industrial warehouse and office space.


Ranlo Dump Site
Following discovery of a debris filled drainage feature on undeveloped industrial property being cleared for development, ESP performed an assessment identifying petroleum, metals and pesticide impact within the debris and underlying soils. The debris originated from a textile mill located in the area. After numerous discussions with NCDENR on appropriate divisional regulatory oversight, ESP performed a detailed soil quality assessment with findings documented in a Comprehensive Site Assessment report.

Approximately 2,300 tons of impacted debris and soil were then excavated and transported off-site for permitted disposal at a municipal solid waste landfill. Following the receipt of acceptable post-excavation confirmatory soil sampling results, ESP prepared a Soil Closure Report requesting NFA. NCDENR's Hazardous Waste Section agreed with ESP's findings and issued an NFA for the incident.



Former Gasoline Station
ESP performed a Phase I ESA on a vacant former gasoline station being considered as a location for a school administration building. The Phase I ESA identified the possible presence of potential orphan USTs and associated piping on the property which were confirmed by ESP’s geophysical exploration services using ground penetrating radar (GPR) and conventional electromagnetic methods. ESP conducted a subsequent Phase II ESA which documented significant areas of petroleum-impacted soil across the site for which ESP recommended abatement. ESP also performed an asbestos survey on the site’s existing structure prior to its planned demolition.


Warehouse/Office
As part of a property transaction, ESP performed a Phase I ESA on this approximate 96,825-square-foot warehouse/office built in 1956. The Phase I ESA identified an existing unused approximate 6,000-gallon heating oil UST and a former 10,000-gallon gasoline UST (previously removed). Based on results of a subsequent limited Phase II assessment, ESP concluded that neither UST had leaked or impacted soil quality. ESP contracted and documented the closure by excavation and removal of the 6,000-gallon heating oil UST. ESP also provided a licensed inspector to conduct an asbestos survey and LBP inspection of the facility prior to upcoming significant renovations.


Former Dry Cleaning Store
Following the completion of a Phase I ESA, ESP assessed soil and groundwater quality in the area of the closed dry cleaning store. During the assessment, ESP cored through the store’s concrete floor in the area where dry cleaning operations had previously been conducted. A shallow soil sample was collected from the cored hole and analyzed for VOCs. A temporary monitoring well was installed downgradient of the dry cleaner and completed on top of bedrock. A groundwater sample was collected and also analyzed for VOCs. Results of the soil and groundwater samples did not reveal impact from past dry cleaning operations.


Former Armory
ESP provided due diligence support for the sale of this approximate 2-acre site. The site’s two-story building reportedly built in 1925 once served as a National Guard Armory. ESP’s review of a recent Phase I ESA report identified a number of environmental concerns associated with the property. ESP conducted a soil assessment which included the collection of eight soil samples in the area of an existing diesel above-ground storage tank, a former gasoline UST, and in the area of recent and past equipment maintenance.


Urban Tract Development
During site development grading of this 22-acre urban tract, six orphan UST locations with multiple tanks were encountered. ESP managed initial abatement of the USTs, made required regulatory 24-hour notification, monitored excavation and permitted off-site disposal of more than 5,000 tons of impacted soil, collected confirmatory soil samples, and completed initial abatement action reports. Received notice of NFA on all six of the UST release incidents while construction progressed.


Urban Site
ESP performed a Phase I ESA on the property which identified the possible presence of an unused gasoline UST. ESP located the UST using ground-penetrating radar (GPR) and an EM61 metal detector. After locating the UST, ESP collected soil samples from depths corresponding to just below the base of the in-place 1,000-gallon gasoline UST. Results confirmed that a release of petroleum had occurred from the UST and the NCDENR was subsequently notified. The UST was then excavated and removed from the tank pit along with 136 tons of impacted soil. Confirmation sampling documented the successful removal of all petroleum-impacted soil above standards from the sides of the excavation; however, since petroleum-impacted soil was found to extend into the water table which was encountered at a depth of approximately 12 feet, ESP installed and sampled a temporary monitoring well as part of Phase I of a Limited Site Assessment. Based on acceptable soil and groundwater sampling results, ESP received a notice of (NFA).


Church Expansion
During grading operations associated with expansion of the church, an orphan heating oil UST along with visibly impacted soils was encountered by a construction contractor. ESP was contacted to assess the release, notify the appropriate regulatory agency, and provide abatement services. Following removal of the heating oil UST, ESP documented the excavation of impacted soils from the former tank pit. Since subsequent confirmatory soil samples revealed that petroleum impacted soils extended into the underlying water table, ESP completed a Limited Site Assessment including the installation of a monitoring well within the immediate area of the tank pit. Resulting groundwater analytical results revealed petroleum levels below NC standards, and ESP obtained regulatory closure for the release.

Industrial Facility
This project involved the assessment and remediation of free-phase and dissolved-phase toluene. Recovery operations consisted of the design, permitting and installation of a dual-phase extraction (DPE) system consisting of an on-site and an off-site recovery well. Connection of the off-site well to the remedial system was accomplished by boring beneath a road and running piping inside 4-inch diameter conduit. During the first 6 months of operation, the DPE system reduced free-phase toluene thickness from 1.4 feet to less than 0.01 feet and decreased the off-site dissolved toluene concentration from 250,000 ppb to 64 ppb.


Former Garage
Performed Phase I and Phase II Environmental Site Assessments on this former automotive repair facility. ESP installed a temporary monitoring well and sampled groundwater, excavated buried automotive debris and sampled underlying soil, cored the building's concrete floor and sampled underlying soil, and analyzed shallow soil samples for lead impact. A total of 218 tons of impacted soil and automotive debris were subsequently excavated and transported off-site for permitted disposal, followed by confirmation sampling. Results of the assessment and abatement activities were reported to SC DHEC.


Automotive Repair Facility
Performed Limited Site Assessment (LSA) activities in the area of a former septic system impacted with chlorinated solvents from an automotive repair facility. Assessment activities included the completion of monitoring wells, collection and analysis of soil and groundwater samples, and performance of a receptor survey. Based on results of the LSA, ESP obtained a NFA for the release


Sewer Line Release Abatement
A grading contractor breached a 6-inch diameter force main sanitary sewer line upgradient of a recently constructed stormwater retention basin. Roughly 100,000 gallons of sewage escaped the pipe and flowed into the approximate 1-acre retention basin. ESP documented site conditions and recommended abatement measures. Approximately 65,000-gallons of liquid were pumped from the basin into pump trucks for off-site disposal, followed by spreading of approximately 17 tons of agricultural lime along the banks, access points, and inside the retention basin. SCDHEC was notified and approved the planned abatement measures. Following a significant rain event, ESP collected a surface water sample from the retention basin’s outfall and a surface water sample from within the basin itself to be analyzed for fecal coliform. Based on fecal coliform results, SCDHEC concluded that no further action was required and the release incident was closed.


Low-income Housing Project
In conjunction with completion of a NEPA Environmental Assessment, ESP performed a sound level study on this planned low-income housing project. The sound level measurements were conducted around the property line perimeter over a 24-hour period. The sound level study was conducted due to the proximity of a highway approximately 250 feet from the site, and the location of nearby railroad tracks. The study was performed using a Larson Davis System 824 sound level monitoring system. The data collected by the system contained various sound level quantities, including exceedance levels and other noise measurements, all measured simultaneously. The system was field calibrated prior to the start of each test period using a Larson Davis Cal 200 field calibrator. A total of 24 sound level test periods were conducted during the study, 16 day-time samples and 8 night-time samples. Study noise levels were referenced to the HUD Noise Guidebook. The calculated day-night average sound level for each sampled location fell below the Site Acceptability Standard limit of 65 dBA.


Renovation of Public Housing Complex
This public housing complex had provided needed rental housing to low-income residents since it was constructed in 1970. The project involved the renovation of 138 units within the complex that had not undergone significant renovation since their construction and many were in disrepair. The public housing complex fronted an active railroad which had to be taken into account in the noise survey calculation. ESP completed both a Phase I ESA and a NEPA environmental review as part of the Tax Credit application process to obtain HUD funding for the renovations. Existing and future noise levels were determined to exceed acceptable HUD standards requiring noise mitigation measures in the design of renovations for some of the units.

Brownfields Property
ESP conducted a Phase I ESA on this Brownfields property formerly occupied by an asphalt plant. Based on Phase I ESA findings, ESP managed environmental liabilities for the client involved in redevelopment of this Brownfields property. Activities included North Carolina Brownfields potential regulatory reporting associated with soil, groundwater and soil vapor studies and waste management.


Brownfields Site
As part of the redevelopment of this Brownfields and REC program site, ESP worked with the former owner, developer, client and regulatory agencies to ensure safe handling of site soils during construction activities and compliance with applicable Brownfields land use restrictions. Project involved monitoring of construction activities, collection and analysis of soil gas and soil samples, contaminated soil disposal and reporting.


Former Textile Dye Manufacturing Facility
Performed a Phase I ESA and asbestos survey on this 220,000-square-foot former textile dye manufacturing facility. Phase I ESA identified a reported release of gasoline from a former UST along with several inactive 15,000-gallon USTs. ESP’s subsequent Phase II assessment activities and an asbestos survey allowed the client to negotiate future environmental costs into the purchase of the property. Once the client purchased the property, ESP was involved in the removal of the inactive USTs, assessment of the previous gasoline release, and the removal of asbestos from the facility. ESP provided the client with documentation of asbestos abatement contractor performance during extensive abatement activities at the facility.


Skilled Care Center
ESP conducted a mold survey and completed a remediation specifications report on the interior space of the center. Based on the collection and analysis of air spore trap and swab samples, the presence of elevated counts of fungal spores in collected air samples and the presence of visible mold growth within the structure were identified. Following completion of a contractor’s mold abatement activities, ESP returned to the site and conducted mold clearance air sampling with a follow-up visual inspection. The visual inspection consisted of verifying the absence of visible mold growth and moisture intrusion issues. A Fluke TiR1 infrared camera was used to survey the subject walls and adjacent floors for signs of temperature differentials that would signify a moisture intrusion issue. No visible mold growth or moisture intrusion issues were observed during the visual inspection. Mold clearance air sampling confirmed that abatement of the previously identified mold had successfully been completed.


Library Building
ESP conducted an asbestos survey and lead-based paint (LBP) inspection on this approximate 9,202-square-foot, two-story library built in 1925 prior to a significant planned renovation. It was concluded that approximately 75 linear feet of 4-inch diameter white pipe wrap located within the building’s crawl space contained asbestos while LBP was identified throughout the interior and exterior of the structure.


University Residence Hall
ESP conducted an asbestos survey of the three-story, 50,000-square-foot residence hall. ESP collected more than 100 samples of suspect asbestos containing materials for testing. Results allowed the University to bid out asbestos abatement services prior to the building’s demolition.


Office Building
ESP conducted an indoor air quality assessment for this two-story, approximately 70,470-sqft office building. From various locations within the building, ESP collected mold spore trap samples utilizing a Megalite pump and VOC air samples utilizing a summa canister. Quantitative measurements including relative humidity, carbon dioxide, carbon monoxide, dew point, temperature, VOCs and particulate were also collected. Sewer gas intrusion was screened utilizing a Yellow Jacket Combustible Gas Detector.


Future Veterans Permanent Housing Site
ESP assisted a local housing authority in the acquisition of an existing apartment complex for rehabilitation into permanent housing for homeless veterans in the Davidson County area. To secure US HUD funding for the project, ESP completed a Phase I ESA, NEPA environmental assessment, and an asbestos/LBP survey for the site. The project is currently proceeding with development plans using procured US HUD funds.


Former Cotton Mill
As part of our NEPA environmental assessment needed to obtain US HUD funding, ESP completed a HUD noise calculator spreadsheet for this planned apartment site. Results of the spreadsheet's noise calculations revealed current noise levels of 68.1 DNL and future (20 years) levels of 69.6 DNL, both above the HUD normally unacceptable level of 65 DNL, but within the normally unacceptable range of 65 to 75 DNL.
