17 December 2021 Project No. 21-6681 Page 9 of 14 reported as sites known or suspected to contain underground storage tanks, or to have been the scene of hazardous materials spills. Additionally, sites permitted to manufacture, utilize, generate, store, treat or dispose of hazardous materials and/or hazardous wastes are identified and located. A list of databases searched, and a glossary of databases are provided in the Executive Summary and Government Records Sections of the EDR, provided in Appendix D. 6.3.1. Subject Property Database Search Property addresses 22770 and 22600 South Union Road, Manteca, California were not listed on any governmental databases within the EDR Report. 6.3.2. Site Vicinity Database Search Sites with recognized environmental conditions surrounding the subject property are typically of concern to the subject property when they are located in an up-gradient direction from the property with respect to the groundwater flow direction (i.e. north- northeast groundwater flow direction). Typically, groundwater would represent the migration medium for contaminants over significant distances. Sites located in equi- gradient or down-gradient directions from the subject property are less likely to impact the subject property. Based on the EDR database search, no sites with environmental conditions were identified surrounding the subject property. Sites with permits to operate USTs, handle/store/transfer hazardous materials and generate hazardous waste are listed on the informational database reports, however, it does not necessarily imply that these sites have impacted the environment. Sites with permits within a ¼-mile search distance from the subject property are noted with emphasis on the immediately adjacent permitted sites. The following UST site was identified by EDR within the search radius: Site Distance & Direction1 Database(s) & Summary Environmental Concern2 Manteca-Lathrop Rural Fire Dispatch 111 ft NW, Higher gradient HIST UST: Listed as a facility that previously operated a 350-gallon gasoline underground storage tank (UST) installed in 1975.
