The conclusions and opinions herein are based on the informationcompiled in the report.No environmental site assessment can wholly eliminate uncertainty regarding the potential forcontamination in connection with a property or project. Performance of this ESA is intended toreduce, but not eliminate, uncertainty regarding the potential for identifying possible sources ofcontamination in connection with the project. Other limitations to this project include the following:We did not access individual parcels within the project area except for a reconnaissanceinspection of the project road improvement corridor.Individual parcel owners were not interviewed.It is possible that surrounding properties used fuel oil in the past. Spills, leaks or releases ofpetroleum products could generate contamination.It is possible that surrounding farms and agricultural land have hazardous waste, such assolvents, pesticides or fuel oil used for agricultural purposes and maintaining farmingequipment.Contamination could have occurred on surrounding properties, where there are/wereaboveground or underground storage tanks that are/were not registered with the Federal,State, and County, or where hazardous petroleum products and maintenance/cleaningchemicals are/were stored or used.2.5 Special Terms and Conditions4
