Exhibit A Multi-Modal Station/Shopping Center Phase II ESA Page 4 Miner Avenue. One boring will be completed to 12 feet bgs at 201 N. Grant Street. One boring will be completed to approximately 75 feet bgs at 701 E. Channel Street. Groundwater and soil samples will be collected to help assess the potential contamination at the properties. Soil samples will be collected from 4, 8, and 12 feet bgs at each boring. The three boreholes completed to approximately 75 feet bgs will be left open during the day to collect depth-to- groundwater measurements once the groundwater has stabilized. The three soil samples collected from each boring will be composited and analyzed for VOCs by EPA Method 8260. Apparent contamination will introduce the need for additional borings estimated at 20% of the original number. Contamination noted in the laboratory results for the composite samples will require discrete soil sample analysis, estimated at approximately 20% of the borings. The discrete soil samples will be analyzed for VOCs by EPA Method 8260, semi- VOCs by EPA Method 8270, and total petroleum hydrocarbons by EPA Method 8015M. In addition, each of the discrete soil samples taken from a depth of four feet will be analyzed for LUFT-5 metals by EPA Method 6010B. Groundwater samples will be analyzed for VOCs by EPA Method 8260. Visually apparent contamination will introduce the need for additional borings estimated at 10% of the original number of borings to approximately 75 feet bgs. Analyses will be conducted at an off-site laboratory. Subtask 2 — Block 2 Borings Seventeen Geoprobe soil borings will be completed on the site designated Block 2. Five borings will be completed to 12 feet bgs at 808 E. Miner Avenue. Two borings completed to 12 feet bgs and one completed to approximately 75 feet bgs will be installed at 822 E. Miner Avenue. Five borings completed to 12 feet bgs will be installed at 210 N. Grant Street. One boring completed to 12 feet bgs will be installed at each of the following sites: 830 E.Miner Avenue, 840 E. Miner Avenue, 848 E. Miner Avenue, and 227 N. Aurora Street. Groundwater and soil samples will be collected to help assess the potential contamination at the properties. Soil samples will be collected from 4, 8, and 12 feet bgs at each boring. The three boreholes completed to approximately 75 feet bgs will be left open during the day to collect depth-to-groundwater measurements once the groundwater has stabilized. The three soil samples collected from each boring will be composited and analyzed for VOCs by EPA Method 8260. Apparent contamination will introduce the need for additional borings estimated at 20% of the original number. Contamination noted in the laboratory results will require discrete soil sample analysis at approximately 20% of the borings. The discrete soil samples will be analyzed for VOCs by EPA Method 8260, semi-VOCs by EPA Method 8270, and total petroleum hydrocarbons by EPA Method 8015M. In addition, each of the discrete soil samples taken from a depth of four feet bgs will be analyzed for LUFT-5 metals by EPA Method 6010B. Groundwater samples will be analyzed for VOCs by EPA Method 8260 (on-site mobile laboratory). Visually apparent contamination will introduce the need for additional borings estimated at 10% of the original number of borings to approximately 75 feet bgs. Analyses will be conducted at an off-site laboratory. Subtask 3 — Block 3 Borings Six soil borings will be completed on the site designated Block 3. Two borings completed to 12 feet bgs and two to approximately 75 feet bgs will be installed at 930 E. Miner Avenue. One boring completed to 12 feet bgs will be installed at both 920 E. Miner Avenue and 911 E. Channel Street. Groundwater and soil samples will be collected to help assess the potential
