Appendix B 

 USE OF BACKSHORE AREA FOR DISPOSAL 



Having a disposal site adjacent to the contaminated beach will 

 result in great saving in time and cost for beach cleanup. One can con- 

 sider creating a dump site in the backshore area adjacent to the location 

 of contamination [25] . An area must be selected that is not subject to 

 erosion. Such an area may meet the requirements that oil drainage would 

 not affect water supplies. 



At the selected site, one or more excavations could be made for 

 the disposal of contaminated beach material. The excavated material 

 should be stored adjacent to the excavation as shown in Figure B-1. The 

 procedure is suitable for sand, gravel or rock beaches. The oil- 

 contaminated material removed should have sufficient sand and gravel 

 to stabilize the fill site and prevent flowing. 



The land fill excavation should be filled with contaminated spoil 

 to a level that is 2 feet below grade and then covered with the stored 

 beach material. This method of disposal is in accordance with the State 

 of California Department of Water Resources requirements for a landfill 

 site. 



The landfill procedure near the site of contamination will result 

 in a considerable saving in cost over the process of transporting the 

 material to a distant landfill site. At the Santa Barbara Spill, the 

 total cost of disposal (hauling, dump fees, road improvement, etc.) 

 is estimated at about $200,000 or $4 per cubic yard. For comparison 

 the cost of operation of a landfill site in the backshore area should 

 be less than $1.00 per yard.
