Brownfields are potentially <br />contaminated sites where the MPCA is assisting with environmental investigations <br />and/or redevelopment activities. <br /> <br />Site 42 – Mcneely Residence, 6687 20th Avenue South, Lino Lakes, MN <br />• Leak Site LS0015090: The identified leak was discovered in 2003, consisted of fuel oil <br />#1 and #2, impacted groundwater, and was issued site closure by the MPCA in 2005. <br />Site closure does not mean that the site is free of contamination. <br /> <br />Site 43 – Lino Lakes Well #4, 6786 Clearwater Creek Drive, Lino Lakes, MN <br />• Leak Site LS0014107: The identified leak was discovered in 2000 and was issued site <br />closure by the MPCA in 2003. The type of product released is not known. Site closure <br />does not mean that the site is free of contamination. <br /> <br />Surrounding Area Sites - Within 500 Feet <br />Three sites (Sites 21, 36, and 41) were identified in the surrounding area (beyond adjacent) within <br />500 feet of the Project Area and are associated with four (4) listings. The surrounding area <br />listings are for stormwater and hazardous waste permits and do not indicate the presence of <br />contamination. <br /> <br />CONCLUSION <br /> <br />All identified Project Area leaks and VIC listings (Sites 1, 5, 25, and 33) and adjoining leak or <br />VIC/PB listings (Sites 8, 10, 20, 42, and 43) pose a contamination risk if future redevelopment <br />involves excavation activities in the vicinity of these sites. Prior to redevelopment in the vicinity of <br />the identified leak or VIC/PB sites, it is recommended that subsurface environmental <br />investigations be conducted to determine if contaminated soil and/or groundwater will need to be <br />managed during redevelopment. <br /> <br />If evidence of contamination or regulated materials are discovered during construction, it is <br />recommended that WSB’s Environmental Group is contacted immediately to ensure all materials <br />are managed in accordance with local, state, and federal regulations.
