05 August 1999 AGE-NC Project No. 98-0497 _ Page 3 of 5 3.0; SCOPE OF WORK Based upon analytical results of soil samples collected upon removal of the two USTs in September of 1998,the PHS-EHD has required this investigation'to determine the lateral and vertical extent of . Hydrocarbon-impacted soil. Initially, AGE proposes to advance and sample three soil probe borings afthe site. However; additional probe borings may be r' quired to adequately define the lateral and vertical extent of hydrocarbon-impacted soil. The investigation will.consist of the following tasks: • Permitting and pre-field work activities; • Soil'sample collection and analysis; • Report preparation. Each of these tasks are discussed below in detail. 3.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES Applicable site assessment permits will be obtained froiy the PHS-EHD. As required by PHS-EHD permitting, a site specific health and safety plan will be repared in accordance with Occupational Safety and Health Guidance Manualfor Hazardous Waste Site Activities (National Institute for' Occupational Safety. and Health Administration, U. . Coast Guard and U.S. Environmental Protection Agency, 1985). Prior to digging activities, each proposed digging location will be clearly marked and a utility clearance obtained through Underground Service AIert. 3.2. SOIL SAMPLE COLLECTION AND ANALYSIS Proposed soil boring locations are illustrated in Figure 2 Based on soil contamination encountered beneath the former USTs at approximately 14 feet bsg ai d from beneath the former dispenser island area, AGE proposes advancement of probe borings int e following locations: • Less than 5 feet north of the former UST 2; • Approximately 5 to 10 feet south of D-I(Dispe ser) soil sample location; • Approximately 5 to 15 feet west of the former UST No. 1; and Approximately 5 to 15 feet north of the former fuel dispenser island area.
