WORK SCOPE <br /> ' CONTINUOUS MONITORING SYSTEMS INSTALLATION <br /> FOR MORTON PAINT COMPANY <br /> ' STOCKTON, CALIFORNIA <br /> PROPOSAL #641 <br /> INTRODUCTION <br /> Groundwater Technology is pleased to present this proposal <br /> to design and install a comprehensive underground tank leak <br /> ' monitoring system at the Morton Paint company facility in <br /> Stockton, California. The facility is a paint manufacturing <br /> ' plant that has on-site storage of gasoline and solvents in ten, <br /> 5 , 000 gallon underground tanks . The tanks contain; acetone, <br /> toluene, xylene, methyl ethyl ketone (MEK) , propylene glycol <br /> methyl ether acetate (PMA) , blended solvents (toluene, xylene, 3 <br /> tanks ) and 2 tanks of unleaded gasoline. The tanks lay end to <br /> end in two rows of five in a single tank pit. we understand that <br /> the tank pit is backfilled with a granular material. <br /> 1 <br /> The monitoring system proposed herein is based upon the <br /> ' requirements of State of California Regional water Quality <br /> Control Board ' s monitoring alternative 2 . Alternative 2 requires <br /> ' soil sampling at the bottom of the tank pit, and the installation <br /> of four groundwater monitoring wells in addition to the <br /> continuous monitoring system. <br /> ' WORKSCOPE <br /> The following work plan prepared by Groundwater Technology <br /> ' provides a detailed overview of the continuous monitoring system <br /> (CMS ) installation. The design specifications for the CMS vapor <br />
