FN Appendix 8—Subject Properties and Adjacent Sites Summaries Port of Stockton, Stockton, CA the site. On June 29th, 2021, a No Further Action letter was issued by the RWQCB. The historical release of nitrate and ammonia to soil and groundwater at this site and its proximity to the Site (<500 ft) represents an HREC for the Site. MOSS TRACT-APN: 145020042321 W.WASHINGTON ST.#D, CARGILL MOLASSES A spill occurred at 2321 West Washington Street#D, west of Port Road 8 and south of Port Road D, and the facility at this site has since been demolished and excavated. Records show past elevated concentrations of both oxidized and reduced nitrogen, and ammonia. In November 1997, the site was issued a No Further Action letter. The historical release of oxidized and reduced nitrogen represents an HREC to the Site. 65 STORK ROAD—HYDROAGRI On July 29th, 1998, a leak of UAN-32% nitrogen occurred from a pipeline (owned by HydroAgri North America, which is listed at 3019 Navy Drive) 5 ft below the surface, beneath the H.J. Baker sulfur handling plant, which is located at 65 Stork Road. The RWQCB has recommended obtaining soil and groundwater samples from the release location to evaluate the necessity of remediation. Because this release of UAN is still an open case, occurred in close proximity to the Site (approximately 200 ft away), and has unknown impacts, it represents a REC for the Site. Moss Tract -APN: 14503001 PORT RD G & 13/14, PORT OF STOCKTON SITE#3 The potential contaminant of concern at Port Rd G and 13/14 is gasoline, and the potential medium of concern is an aquifer used for drinking water supply. In February 2008, two 12,000- gallon USTs were removed from the site. Excavation later removed 180 cubic yards of petroleum-impacted soil. On November 91h, 2012, the site was issued a No Further Action letter. The historical release of gasoline to groundwater and its proximity to the Site (<500 ft) represents an HREC for the Site. Moss Tract -APN: 14503012 2115 WEST WASHINGTON STREET, PACIFIC MOLASSES COMPANY In 1988, between 500 and 1,000 gallons of UAN spilled and pooled at the south end of the site at 2115 West Washington Street. In 1990, about 2,500 cubic yards of soil were removed to maximum depth of 12 ft, and soil and groundwater samples were collected and analyzed. Results of soil and groundwater analyses indicated that concentrations of nitrate remaining in soil and groundwater did not exceed the maximum contaminant level. On April 15th, 2015, a No Further Action letter was issued. The historical release of UAN at Pacific Molasses Company and its proximity to the Site (<500 ft) represents an HREC for the Site.
