The Site <br />is currently operating as a Quick Stop gas station utilizing three USTs with multi-tenant <br />commercial business space. <br />WKA understands a Phase I Environmental Site Assessment (Phase I ESA) was performed by <br />ALFA Environmental Assessment Services of Danville, California. A review of the Phase I ESA, <br />dated January 11,2021, identified Recognized Environmental Conditions (RECs) associated <br />with the current and historical operation of USTs for vehicle refueling. <br />Soil Sample Collection <br />To assess the potential for environmental impact at the Site due to the REC identified in the <br />Phase I ESA, WKA proposes performing soil sampling and laboratory analyses near locations <br />now occupied by the USTs. <br />Prior to soil sampling activities, WKA will prepare a site-specific health and safety plan and mark <br />the location of each soil boring with white paint. WKA will contact Underground Service Alert <br />(USA) a minimum of 72 hours before drilling to have their members mark the Site for <br />underground utilities. Additionally, WKA will coordinate with a private underground utility locator <br />to identify any underground utilities not marked by the USA members. WKA will contact the San <br />Joaquin County Environmental Health Department (SJCEHD) a minimum of 48 hours prior to <br />soil sample collection to schedule a grout inspection for destroying the soil borings. <br />www.wallace-kuhl.corn
