CENTRAL VALI REGIONAL WATER QUALITY ONTROL BOARD <br /> 21 September 1998 <br /> DISCHARGER: Port of Stockton <br /> LOCATION & COUNTY: Stockton, San Joaquin County <br /> CONTACT(S): Jay Jahangiri, Environmental Director <br /> INSPECTION DATE: 6 July 1998 <br /> INSPECTED BY: Patricia Leary <br /> ACCOMPANIED BY: Jay Jahangiri and Tim Loveland, Port of Stockton <br /> John Benedict, San Joaquin Valley Air Pollution Control District <br /> J.F. Jerwa, Stevedoring Services of America <br /> Tom Mogan, Metropolitan Stevedore Company <br /> OBSERVATIONS AND COMMENTS: <br /> Background <br /> I had received various complaints over time that sulfur loading on the Port's conveyor owned by the <br /> Port District(and operated under contract by Stevedoring Services of America) created significant sulfur <br /> dust in the air, and spilled significant quantities of sulfur into the Deep Water Channel. At <br /> approximately 1000 on 6 July 1998 I received a call that the Port conveyor was operating that.day, and <br /> the adjacent conveyor owned by Metropolitan Stevedore Co. would be operated the next day. It <br /> provided an opportunity to observe both conveyors to determine the effectiveness of the BMPs to meet <br /> BAT standards. Due to concerns about sulfur dust air emissions, I notified Mr. John Benedict of the <br /> San Joaquin Valley Air Pollution Control District to arrange a joint inspection. <br /> Observations <br /> I arrived with John Benedict and located Tom Mogan of Metropolitan Stevedore Co., who accompanied <br /> us to the conveyor area. Mr. Mogan notified Jay Jahangiri that we were there to inspect the sulfur <br /> conveyor area. The Port's conveyor was being operated by Stevedore Services of America. Shortly <br /> thereafter, representatives from the Port and Stevedoring Services of America also arrived at the site. <br /> There was sulfur spillage along the length of the conveyor. The spillage was on the ground surface, and <br /> on paved areas along its length. There was no secondary containment of the spillage. The ship loader <br /> portion of the conveyor was spilling significant quantities of sulfur onto the dock and directly into the <br /> water. The water surface was covered with sulfur between the ship and the bank. There was a blue tarp <br /> hanging down off the ship, intended to catch sulfur from spilling into the water, but it provided <br /> insufficient coverage to be ineffective as a solution. Workers placed a second tarp next to it during the <br /> inspection. Plywood was laid on the dock surface to collect spillage, but sulfur spilled beyond the limits <br /> of the plywood, and fell through openings in the dock to the river. <br /> Approved: <br />
