City of Ramsey <br /> Project B1610732 <br /> January 10, 2017 <br /> Page 7 <br /> 113.2.c. Hydrogeology <br /> The depth to groundwater in the vicinity of the Site is estimated to be 15 to 30 feet below land surface. <br /> Based on previous investigations at the Site,groundwater was measured at depths of approximately 20 <br /> to 24 feet below land surface. <br /> According to published geologic information, the regional groundwater flow direction within the <br /> unconsolidated deposits in the Site vicinity is generally south-southwest (Palen et al., 1993). <br /> The Site-specific groundwater flow direction was not determined through direct measurement during <br /> this Phase I ESA. Additional field investigation, beyond the Scope of Services of this Phase I ESA, would be <br /> required to determine this information. <br /> 13.3. Regulatory Report <br /> We obtained regulatory database information pertaining to the Site and surrounding area from <br /> Environmental Risk Information Services, Ltd. (ERIS).The ERIS report is a compilation of records of <br /> facilities that are included on current federal and state environmental regulatory databases. The <br /> databases were searched based on the specified minimum search distances from the Site as established <br /> by ASTM Practice E1527-13. <br /> The ERIS report also includes a description, source reference, date of acquisition, and the specified <br /> approximate minimum search distance criteria for each database and list. A copy of the ERIS report is <br /> attached in Appendix D. <br /> We reviewed the ERIS report to identify records that indicate known or potential recognized <br /> environmental conditions on the Site and/or surrounding area and to evaluate the likelihood for those <br /> recognized environmental conditions to impact the Site based on the information obtained in this Phase I <br /> ESA. <br /> 113.3.a. Site <br /> The Site is listed on the following federal and/or state databases in the ERIS report: <br /> ■ Sunfish Express, 6401 Highway 10.The ERIS report indicates that the Site is listed on the <br /> underground storage tank(UST) and What's In My Neighborhood (WIMN) databases. One <br /> 20,000-gallon gasoline UST, two 10,000-gallon gasoline USTs, and one 10,000-gallon diesel <br /> UST are registered to the Site. All four tanks are listed as installed on October 31, 2002 and as <br /> out of service (not formally temporarily closed). All of the tanks are double-walled fiberglass <br /> with spill containment, overfill protection, and leak detection. <br /> BRAUN <br /> INTERTEC <br />
