In addition, an update to the health and safety plan presently on-file will be prepared in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985).

Figure 2 depicts areas with letter and borings are grouped as applied to each area. Area A • One boring will be advanced to depth of 20 feet below surface grade (bsg) near a dry well area (D), • One boring will be advanced to depth of 15 feet bsg near a septic system area (S), Area B • One boring will be advanced to depth of 20 feet below surface grade (bsg) near a dry well area (D), • One boring will be advanced to depth of 15 feet bsg near a septic system area (S), Area C • Two borings will be advanced to a depth of 20 feet bsg near a septic system area (S), Area D • One borings will be advanced to a depth of 20 feet bsg near a septic system area (S), Area E • Two borings will be advanced to a depth of 20 feet bsg near the former UST release area to define any additional contamination (type and distribution) • One borings will be advanced to a depth of 20 feet bsg near a septic system area (S), • Six shallow borings will be 5 feet bsg near the former UST release area to define any residual from impacted soil piles deposited for disposal.
