(conoco) Interoffice Communication To M. L. Ashby From P. D. Despres Date July 22, 1982 subject Containment of Stormwater in the Tank Farm Area The stormwater runoff from the tank farm area currently drains immediately to the secondary wastewater treatment facility. Routine containment of this water within the dikes and periodic draining to the secondary would help alleviate the load on the secondary basins during periods of heavy rainfall. The runoff from the tank farm area comprises approximately 12% of the total surface runoff from the VCM Plant. Routine isolation of the tank dike areas will also help contain any toxic material from the EDC.or by-product tanks in case of a tank rupture. There are a total of eight tank dike drains that should be closed: three interconnecting lines and five effluent drains (see Figure 1). These valves should be kept closed at all times. Draining should be done on the weekends if necessary and secondary basin levels permitting. Routine containment of the runoff water will cause a few changes in operations and maintenance policies and practices. Materials and equipment left inside the dike area should be removed either from the tank farm area or to a high accessible location. Care should be taken not to clutter the walkways with this material overnight. If there are any questions or comments, please contact me at Extension 5049.
