paraphase text: The various containment systems offer more than just differences in cost; time considerations are also crucial. Installing a specific containment system takes a certain amount of time, which is an expensive factor in any engineering project. This report will present our recommendations for choosing between a GCL and a CCL. We'll begin by addressing the most immediate benefit: a cost saving of $160,000. This saving is likely to grow as gasoline prices continue to rise. For instance, the cost per cubic yard with the CCL system, currently at $20, could rise to $25 or more
