The report indicates that recent <br /> conveyor operations caused significant quantities of sulfur to be spilled directly into the Deep Water <br /> Channel, onto the dock and its supporting timbers, and onto the ground along the length of the conveyor. <br /> The ship loader generates significant quantities of sulfur dust which settles over the Port property and <br /> into the Channel. These operations demonstrate that neither the Port nor Stevedoring Services of <br /> America has been implementing adequate Best Management Practices (BMPs). <br /> Recent improvements proposed by the Port to enclose the conveyor along the ground, and to use an <br /> improved tarp collection system on the inclined conveyor and ship loader will be helpful, and are a <br /> significant step towards improving the quality of storm water runoff in the area. However, tarp usage to <br /> collect spills may be difficult to properly implement by those performing the work. The problem of <br /> sulfur dust emissions from the ship loader also does not appear to be addressed. <br /> Waste Discharge Requirements Order No. 97-042 (NPDES No. CA0084077) was adopted 28 February <br /> 1997 for the Stockton Port District, for Facility-Wide Storm Water Discharges from the Municipal <br /> Separate Storm Sewer System and Non-Storm Water Discharges from the Port of Stockton. Non-storm <br /> water discharges include all discharges from the Port facility that are not solely comprised of storm <br /> water runoff. Material and product handled at the Port which is spilled directly to surface water is <br /> considered a non-storm water discharge. <br /> Discharge Prohibition A.5. states: <br /> "The discharge of material by the Discharger associated with shipping, receiving and <br /> storage activities conducted at the Port, such as, but not limited to, sulfur, coal, cement, <br /> petroleum coke, raw sugar, copper concentrate, and fertilizers, to a surface water is <br /> prohibited. The Discharger shall not be in violation of this prohibition if it demonstrates <br /> that the discharge has not caused an exceedance of a water quality objective, and that it <br /> has applied best management practices that reflect the Best Available Technology <br /> Economically Achievable for nonconventional and toxic pollutants (BAT), and Best <br /> Conventional Technology Economically Achievable for conventional pollutants (BCT), to <br /> minimize or avoid such discharges." <br /> California Environmental Protection Agency <br /> Ca Recycled Paper <br />
