HAZNET Sites database consists of data that is extracted from the copies of hazardous waste ( 3 .1) <br /> manifests received each year by the DTSC. <br /> The subject property was identified during the HAZNET database search, as further discussed <br /> below: <br /> • The subject property, occupied by the prior tenant McGregor Printing Corporation, was <br /> identified with three HAZNET database listings. The dates of the disposal of hazardous <br /> materials are unknown. McGregor Printing Corporation had 2.29 tons of waste oil and �3' <br /> mixed oil and 0.2085 tons of unspecified oil-containing waste transported from the subject <br /> property to Yolo County for disposal. McGregor Printing Corporation had 0.4587 tons of <br /> •.. unspecified aqueous solution transported from the subject property to Los Angeles County to <br /> be recycled. Due to the lack of a documented release of hazardous materials or any <br /> indication of spills, the transfer of hazardous materials for disposal is not anticipated to be an <br /> environmental concern. Refer to Section 4.3 for further discussion of the historic occupancy <br /> by McGregor Printing Corporation. <br /> Underground/Aboveground Storage Tanks (UST/AST) List is a comprehensive listing of �) <br /> registered underground and aboveground storage tanks located within the State of California. <br /> Eight sites within a '/-mile radius of the subject property were identified during the UST/AST (3,6_7> <br /> database search. Due to the lack of a documented release or factors discussed in the LUST <br /> segment of Section 5.3, the storage of hazardous materials within registered tanks is not a <br /> significant environmental concern. <br /> Leaking Underground Storage Tanks (LUST) List is a list produced by the Regional Water <br /> Quality Control Board (RWQCB) of known sites with current or former leaking underground <br /> storage tanks on the premises. <br /> Nineteen sites within a '/z-mile radius of the subject property were identified during the LUST <br /> database search. Of these sites, eighteen were plotted in excess of '/g-mile from the subject (71-�, <br /> property, and based on the relative distance are not expected to represent a significant <br /> environmental concern. The remaining site is further discussed below: <br /> • United Parcel Service at 1532 North Broadway was plotted by the database 601 feet north- <br /> northeast (hydrologically upgradient) of the subject property. Files were reviewed for this <br /> property at the SJCEHD related to this LUST case. <br /> Documentation was on file indicating that a UST removal was conducted at this property in /�1 Lo <br /> 1991. The USTs removed were listed as one 10,000-gallon gasoline UST and one 500- l <br /> gallon waste oil UST. Soil and groundwater sampling were conducted in the vicinity of <br /> these USTs, and mild amounts of contamination were found near both. This site was listed <br /> as a leaking underground storage tank (LUST) site. Surrounding soils were subsequently <br /> excavated prior to installation of the current UST system. In 1991, a case closure letter was <br /> Phase I Environmental Site Assessment AEI <br /> Project No.274968 <br /> ,.,. October 11,2007 <br /> Page 19 <br />
