CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br />CENTRAL VALLEY REGION <br />CLEANUP AND ABATEMENT ORDER NO. R5-2008-0707 <br />FOR <br />MARTIN OPERATING PARTNERSHIP AND THE PORT OF STOCKTON <br />MOLTEN SULFUR PROCESSING PLANT <br />SAN JOAQUIN COUNTY <br />This Order is issued to Martin Operating Partnership and the Port of Stockton (hereafter <br />together referred to as "Discharger") based on provisions of California Water Code Section <br />13304, which authorizes the Regional Water Quality Control Board, Central Valley Region, <br />(hereafter Regional Water Board) to issue a Cleanup and Abatement Order, and California <br />Water Code Section 13267, which authorizes the Regional Water Board to require the submittal <br />of technical and monitoring reports. <br />The Executive Officer of the Regional Board finds, with respect to the Discharger's acts, or <br />failure to act, the following: <br />Martin Operating Partnership (Martin) owns and operates a processing plant that <br />converts molten sulfur into sulfur pellets (i.e., "prill"). The Port of Stockton (Port) <br />owns and leases the land to Martin. Martin began prill operations in 1991. <br />The Discharger's facility is located at 2717 West Washington Street at the Port of <br />Stockton. The 4.62-acre property is described by Assessor's Parcel Number 145- <br />030-01 in Section 9, T1 N, R6E, MDB&M. The site is within the Port's Eastside <br />Complex, east of the San Joaquin River, and south of Wharf 10-11, as shown on <br />Attachment A, which is incorporated herein and made a part of this Order by <br />reference. <br />The facility receives molten sulfur in tanker trucks, transfers the liquid sulfur to a <br />storage vault, and subsequently processes/pelletizes the molten sulfur into prill. An <br />overhead conveyor moves the finished prill to the stockpile area. Pull is dropped <br />from the overhead conveyor onto stockpiles. The stockpiles are uncovered and are <br />stored outdoors on a 200x400" asphalt floor, referred to as the prill storage area. A <br />windbreak encircles the stockpiles, but is below the top of the stockpiles. The <br />Discharger stockpiles the prill until conveyed to cargo ships docked in the nearby <br />Stockton Deep Water Shipping Channel. Shipping occurs approximately six to eight <br />times per year. <br />The facility includes below-grade sumps, two ponds, one aboveground storage tank <br />(AST), a prill conveyor system, a molten sulfur unloading area, vault, <br />process/pelletizer area, and prill storage area. The Discharger's facility layout is <br />shown on Attachment B, the Site Layout map, which is incorporated herein and made <br />a part of this Order by reference.
