The purpose of this chapter is to adopt recognized standards for the design, construction, and placement of above-ground tanks to collect used oil from private individuals for recycling purposes pursuant to RCW 19.114.040.

These standards are designed to fulfill the legislative intent as stated in RCW 19.114.010 which states "Improper disposal of used oil creates leaching problems within landfills, is a significant source of water pollution, has a detrimental impact on the fisheries industry, and contributes toward the overall shortage of energy resources. In light of these harmful consequences and the ease with which used oil can be recycled, the legislature declares that it is the policy of this state to collect and recycle used oil."
