Jeff McGriff, Project Engineer, reported that the dredge would be used to “clean two 70-year old industrial storm water clay-lined lagoons that have not been cleaned for 20-30 years. One lagoon is 10 acres; the other is 2 acres.” “The depth of the lagoons (from surface to bottom, excluding sediment) is 8-9 feet. The number of feet of water between the surface and the top of the sediment is 2 feet. The material to be dredged is sandy, silty, and “sludgey” – like a thin pudding. “They plan to dredge 4-hours a day, year round, for 10 years. They have “hot spots” they intend to dredge first, and after they ‘get a feel for it’ they will develop a regular process. Mr. McGriff reports that there are big chunks of concrete in one corner and some stumps in another corner. Lion Oil’s hope is that by dredging the lagoons, they will be able to remove the concrete and stumps – thereby creating more capacity in the lagoons. Slurry will be discharged to a holding pond where the dredged material will be treated and pumped out. “Lion oil’s goal is to develop environmentally friendly and healthy practices, become compliant with EPA regulations, and increase the capacity of their lagoons” according to McGriff. Mr. McGriff said “the purchase of a dredge is a much more sound financial solution compared to alternatives such as draining the lagoons and dealing with the environmental effects as well as the expenses of hiring others to cleanup and cart the dredged material away.”
After SRS Crisafulli personnel trained Lion Oil staff to operate the dredge and helped put the Rotomite-SD110 into operation, Jeff McGriff wrote SRS Crisafulli’s Sales Manager the testimonial shown above.
