Monitoring wells <br /> MW-6, MW-7, MW-9, MW-12, MW-13, and MW-14 were abandoned by overdrilling. Monitoring <br /> wells MW-4, MW-10, and MW-11D were abandoned by pressure grouting. Monitoring wells MW-2, <br /> MW-3, and MW-5 were transferred to the Lin coin Center Environmental Trust for use in their open <br /> environmental case. It is anticipated.that these activities sufficiently fulfill Chevron's responsibility <br /> in the aforementioned local and regional environmental cases.
