City of Ramsey Project B1610732 January 10, 2017 Page 7 B.2.c. Hydrogeology The depth to groundwater in the vicinity of the Site is estimated to be 15 to 30 feet below land surface. Based on previous investigations at the Site, groundwater was measured at depths of approximately 20 to 24 feet below land surface. According to published geologic information, the regional groundwater flow direction within the unconsolidated deposits in the Site vicinity is generally south-southwest (Palen et al., 1993). The Site -specific groundwater flow direction was not determined through direct measurement during this Phase I ESA. Additional field investigation, beyond the Scope of Services of this Phase I ESA, would be required to determine this information. B.3. Regulatory Report We obtained regulatory database information pertaining to the Site and surrounding area from Environmental Risk Information Services, Ltd. (ERIS). The ERIS report is a compilation of records of facilities that are included on current federal and state environmental regulatory databases. The databases were searched based on the specified minimum search distances from the Site as established by ASTM Practice E1527-13. The ERIS report also includes a description, source reference, date of acquisition, and the specified approximate minimum search distance criteria for each database and list. A copy of the ERIS report is attached in Appendix D. We reviewed the ERIS report to identify records that indicate known or potential recognized environmental conditions on the Site and/or surrounding area and to evaluate the likelihood for those recognized environmental conditions to impact the Site based on the information obtained in this Phase I ESA. B.3.a. Site The Site is listed on the following federal and/or state databases in the ERIS report: • Sunfish Express, 6401 Highway 10. The ERIS report indicates that the Site is listed on the underground storage tank (UST) and What's In My Neighborhood (WIMN) databases. One 20,000-gallon gasoline UST, two 10,000-gallon gasoline USTs, and one 10,000-gallon diesel UST are registered to the Site. All four tanks are listed as installed on October 31, 2002 and as out of service (not formally temporarily closed). All of the tanks are double -walled fiberglass with spill containment, overfill protection, and leak detection. B RAU N INTERTEC
