• • • improvements to create an interior storage area, exclusive of a special deluge-type , fire sprinkler system. Dopaco is presently negotiating with the Fire Marshall to establish the final criteria for fire protection in an enclosed storage area. • Recommended Action Dopaco should finalize its economic evaluation of alternative drum storage areas and initiate steps to upgrade or relocate its existing drum storage area. At this stage it appears that • relocation of the storage area would be economical. In the event stringent fire protection requirements are imposed, it may be prudent for Dopaco to examine the exterior storage area in greater detail to refine the cost estimate for this alternative . • FUGITIVE CONNECTIONS TO STORM DRAINS System Description Storm drainage from the Gold Bond property is conveyed directly to McDougald Slough through either a City of Stockton storm drain • located in West Church Street or an onsite , exterior storm drain system located along the southern and eastern portions of the property (see Figure 3 ) . The City storm drain in West Church Street extends from a manhole at the Yosemite Street intersection to the discharge point in • McDougald Slough at the Church Street culvert. The City storm drain includes approximately 610 feet of 21 inch and 120 feet of 30 inch pipe and varies in depth from 9 to 14 feet. Connections to the City storm drain from the Gold Bond property occur at Yosemite Street ( 12 inch and 21 inch connections) and at Stockton Street near the Guard House (10 inch connection). • The onsite storm drains consist of a number of yard drains which discharge directly to McDougald Slough. No piping diagrams or schematics are available for this drain system. Physical inspection of several of these drains confirmed that they are shallow (2 to 3 feet deep) and are o routed toward war for draigh. are • No connections of inplant piping possible due to the shallow depth of the drains. The inplant drainage system consists of floor drains , sanitary sewers and process piping. Again, no piping schematics are available which characterize drainage paths from all areas of the • facility. It is reasonable to assume that all major process and sanitary piping is connected to the City's sanitary sewer system, since evidence of discharges from these sources to the storm drain have not been observed. Some question remains regarding the connection of isolated floor drains to the storm sewer, however. • 12 •
