NOA Drywell Closure and Investigation Work Plan Page 14 of 16 <br /> ' March 18, 2014 <br /> Revised March 20, 2014 <br /> 5.3 Alternative Curing System <br /> An Immersion method of concrete curing will henceforth be used. Concrete test specimens will <br /> be cured by total immersion in tubs filled with water. This curing method is commonly used in <br /> laboratories for curing concrete test specimens. This method has been used since <br /> discontinuation of the Fog Curing System on March 6, 2014. <br /> 5.4 Alternative Curing System Waste Fluids Disposal <br /> The alternative Immersion method will not require continuous drainage or disposal of waste <br /> ' fluids. The water will be reused for the curing of multiple concrete test specimens. The tubs will <br /> be stored inside of the Concrete Cure Room. <br /> It is anticipated that three (3) 150 gallon water tubs will be used. The water will only require <br /> changing annually. The waste water is planned to be disposed of at Forward Landfill, Inc. in <br /> Manteca, San Joaquin County, California. Prior to disposal, the waste water will be analyzed by <br /> ' a certified analytical laboratory for landfill profiling. <br /> 5.5 Alternative Curing System Waste Containment <br /> The tubs will be stored inside of the Concrete Cure Room. This room is fully contained. The <br /> floor drain will be grouted and the walls, ceiling, and floor are concrete. Environmental <br /> ' contamination will not result from a spill. <br /> 6.0 TIME SCHEDULE <br /> The following dates indicate the proposed time schedule for this project.
