4.0 EMERGENCY CLEANUP AND MONITORING OPERATIONS <br />The pipeline was shut down on Sunday morning (February 23, 1986) at 8 <br />o'clock. IT Corporation was called in and clean-up and monitoring <br />commenced later that same day. Further details of emergency operations are <br />as follows: <br />4.1 General Site Cleanup <br />As a result of the flooding, petroleum products contained by the <br />landfill were carried into the adjacent Whiskey and Trapper Sloughs. To <br />contain the spread of product, IT has installed permanent and disposable <br />type booms at critical points along the edges of the sloughs and across the <br />ends of a connecting tidal culvert. The floating product has been <br />collected by vacuum and absorption with floating pads. IT have also <br />disposed of solid debris collected from the landfill site, the levees and <br />surrounding surface waters. <br />4.2 Pipeline Remediation <br />Plans were formulated to re-route the pipeline so that disruption of <br />fuel supplies to customers would be minimized. Excavations to the pipeline <br />were implemented and a new line installed. The old section is now being <br />purged and cleaned. It is planned that the abandoned pipe section will be <br />grouted and left in place. <br />4.3 Product Drainage and Removal <br />A number of pits and trenches have been excavated at the landfill <br />site. A total of 9 separate excavations were in place by March 6. These <br />excavations include a large 15 ft. deep pit; a 60 ft. long trench (5 ft. <br />wide and 6 ft. deep); and 7 small pits and trenches ranging from 3 to 10 <br />-6-
