❑� Northwest Pipe Spill Prevention, Control, and Countermeasure (SPCC) Plan 9 �-- Company Tracy Plant The Tracy Plant is bounded on the north by West Linne Road, beyond which is residential development; on the east by vacant land; on the south by vacant land; and on the west by a concrete block manufacturer. The Tracy Municipal Airport is located just southwest of the Tracy Plant. 4.2 Facility Operations The Tracy Plant produces concrete-lined steel pipe and poured concrete pipe for water transmission applications. Various manufacturing operations are involved depending on the required pipe configuration: • Steel pipe is spiral welded from steel coil. Concrete and sand mixing operations produce concrete for lining the pipe. • Poured pipe is manufactured in the Verticast Department. Various coatings and tape wrap are applied to the finished pipe depending on the end-use requirements. Form oils and release agents are used in this process. • A vehicle maintenance function supports onsite forklifts and trucks. The majority of the Tracy Plant's aboveground petroleum storage capacity is associated with the storage of motor oils, automatic transmission fluid, waste oil, gasoline, and diesel fuel by the vehicle maintenance function (Figure 4.5). Operational areas described above are identified on the facility diagram (Figure 4.4). 4.3 Discharge History There have been no releases of oil at this facility which exceed reportable release thresholds established in 40 CFR § 112.4(a) or California HSC § 25270.8. Reportable oil release thresholds are discussed further in Section 5.3 of this SPCC Plan. 5.0 Discharge Prevention — General SPCC Requirements The goal of a SPCC program is to prevent the release of oil into the environment through a combination of containment measures, routine inspection, and employee training. In the event of a release, the SPCC program also provides procedures for responding to the release and notifying the appropriate regulatory authority. This section contains a description of these general SPCC program elements, which are required by 40 CFR § 112.7 and HSC 25270.8. 5.1 Facility Conformance with Applicable Requirements Unless stated otherwise, this SPCC Plan conforms to the general requirements for spill prevention, control, and countermeasure plans required by 40 CFR § 112.7.
