5 SITE SUMMARY 1.0 SITE CONDITIONS This section discusses the observed conditions on the Site, as defined as the properties (Tax Parcels # s and ) on which the Disposal Area is located. The Disposal Area is defined as the area observed or reported to have been used for waste placement or burial. The boundary (perimeter) of this area is the observed limit of waste material based on field observations and the inferred limit based on a review of historical aerial photographs. The site visit was conducted on October 13, Photographs illustrating site conditions are included in Appendix D. The Site is located in Stanly County, near Albemarle, NC. Driving directions to the Site from the intersection of NC-138 and NC-24/27 Bypass are as follows: 1. Drive west on NC-24/27 Bypass for about ¾ mile. 2. Turn left onto Coble Avenue and drive to the security gate of the City of Albemarle Disposal Facility. 3. The City of Albemarle Dump is located beyond the security gate along Long Lake Creek. 1.1 On-site Structures Buildings associated with the City of Albemarle Sewage Disposal Facility are located on the Site. The Facility consists of waste ponds, paved roads, two buildings, and numerous storage sheds. An unused steel storage tank used for polymer is located on the southeastern part of the Disposal Area, and a sludge dispenser pipe used to release waste into trucks is located on the central part of the Disposal Area. City of Albemarle Dump NONCD

6 1.2 Current Site Usage According to Raymond Allen, Albemarle City Manager, the Site is used as the Sewage Disposal Facility for the City of Albemarle. The Utilities Department uses the northwestern part of the Disposal Area to store wood telephone poles. 1.3 On-Site Water Supply Wells and Intakes No on-site water supply wells were observed on the Site during the site visit. A water meter and fire hydrants were observed on the Site during the site visit. 1.4 Surface Water Features Poplin Creek flows from north to south along the southeastern boundary of the Disposal Area. Long Lake Creek flows from northwest to south along the southwestern boundary of the Disposal Area. Long Lake Creek and Poplin Creek were about 25 feet wide with slow flowing clear water. Both creeks flowed on exposed boulders. Some disposal material was observed in the stream beds including tires, water heaters, glass, and concrete. A drainage ditch was observed along the northern boundary of the Disposal Area. The drainage ditch was dry with exposed disposal material in the southern drainage ditch bank. Observed disposal material included glass, plastic, clothing, tires, and 55-gallon drums. 1.5 Disposal Area Access to the Disposal Area is from Coble Avenue and through a security gate with key pad (Photo 1). The Disposal Area occupies 7.6 acres based on the estimated Disposal Area perimeter shown on Figures 1 through 3. The Disposal Area generally slopes to the southwest. A comparison of the topography from the 1978 USGS 7.5 minute topographic quadrangle map (10 foot contours) with the 2005 City of Albemarle Dump NONCD

7 topographic map from NCDOT GIS Branch (20 foot contours) indicates that up to about 10 feet of cut material may have been removed from the northwestern part of the Disposal Area. The removed cut material is estimated based on a comparison of topographic maps of different vintages constructed using different methods. The reported years of operation were from the early to mid 1930 s to 1972, so the 1978 USGS map (based on 1977 aerial photographs) may have represented the land surface at or near the end of the disposal period. Differences between elevations on the maps may reflect actual elevation changes or may be apparent differences due to the different map making methods. The elevation comparisons are approximate and differences in scale and methods of mapping are not sufficient to evaluate some changes in topography. GPS coordinates were taken of the Disposal Area perimeter. The approximate Disposal Area perimeter is illustrated on the figures and on aerial photographs in Appendix E. A table of GPS coordinates for the Site entrance and the Site perimeter is presented in Table 1. The Disposal Area perimeter location is approximate and is based on visual observations made at the time of the site visit and interpretation of aerial photographs. Figures 4 and 5 show LiDAR shaded relief superimposed on the Disposal Area. 1.6 Disposal Area Conditions The Disposal Area was covered with a paved road, grass, and deciduous trees of two to four feet in diameter. Disposal material was observed along the stream banks of Poplin Creek along the southeastern boundary of the Disposal Area and Long Lake Creek along the southwestern boundary of the Disposal Area. The observed disposal material along the stream banks included concrete, corrugated metal, glass, tires, and water heaters. Exposed disposal material was also observed along the northern boundary of the Disposal Area which included 55-gallon drums, glass, plastic, tires, clothing, asphalt, concrete, and white goods. The northwestern part of the Disposal Area was covered with dirt and stacked wooden telephone poles and the southeastern part of the Disposal Area was covered with grass. City of Albemarle Dump NONCD

8 The observed Disposal Area was on two tax parcels, Parcel Numbers and The perimeter of the Disposal Area was visually evident with the majority of the Disposal Area on Parcel No The southeastern perimeter of the Disposal Area extended onto Parcel No The southeastern and southwestern boundaries of the Disposal Area are located within the 100 year flood zone. No notable erosion, depressions or hummocky topography, offensive odors associated with the old landfill, stained or discolored soils, or slope failures were observed during the site visit. 1.7 Evidence of Human Activity Activities associated with the operation of the Sewage Disposal Facility were observed during the site visit. 1.8 Potential Landfill Gas Migration Pathways Potential gas migration pathways observed on the Disposal Area included an underground pipe from the steel storage tank used for polymer to Long Lake Creek, underground pipes from the sewage disposal facility to the sludge dispenser pipe, and a sewer line along the southwestern side of the Disposal Area. The pipeline locations to the steel storage tank and sludge dispenser were not observed. The sewer line right-of-way and manholes were observed. Potential gas migration pathways observed on the Site included buildings associated with the sewage disposal facility, and underground sewer and water lines. 1.9 Physical Barriers Site access is provided by Coble Avenue. Site access for vehicles is blocked by a security gate at the entrance to the Sewage Disposal Facility. Access to the northern part of the Disposal Area is City of Albemarle Dump NONCD

9 limited by a security gate. Physical barriers were not observed along the eastern, western, or southern boundaries Other Pertinent Information Some history of the Site was obtained during conversations with persons familiar with the Site. The information obtained indicates that: Mr. Raymond Allen, Albemarle City Manager, stated that the Site operated from the early to mid 1930 s to Mr. Allen stated that the waste placed at the Site was generated by the City of Albemarle. Mr. Allen stated that since the Site was closed in about 1972, the Site has been used by the City of Albemarle Sewage Disposal Facility. Notes from conversations with people familiar with the site are included in Appendix C. The information obtained from these conversations has not been verified or confirmed.
