This letter summarizes activity since our preliminary EMP report of late January and our recent conversation. The Order addressed two issues: The evaluation monitoring plan to assess the extent of groundwater impact and closure of the areas containing refuse that are not now provided with closure cap. Evaluation Monitoring Plan (EMP) The second set of groundwater monitoring wells were drilled and sampled in the week of February 24, 2012, for a total of six sampling points to date. We expect the analyses from the February wells in the third week of March. Hopefully these data will allow us to establish the extent of release and complete the Evaluation Monitoring Program and Engineering Feasibility Study. We were fortunate that we had both Vector(now Geologic)and Gregg Drilling under contract when the Order was issued so that we could immediately direct their efforts to this component of the Order. Landfill Closure Plans and specifications for the Final Cover Expansion Design were delivered to RWQCB staff on October 9, 2011 in accordance with Item 1 on page 5 of the Order. These documents reflected the conceptual design approved by RWQCB staff in 2008 and we anticipated that the detailed design would be quickly approved, and with luck, construction could occur in 2012. As with Vector and the EMP,we had a contract in place with Shaw Environment and Infrastructure(Shaw), and we immediately applied that resource design upon receipt of the Order. However, this design was found not to be acceptable based on technical grounds, and we are therefore preparing to re-design closure of this landfill. Unfortunately, our contract budget with Shaw was consumed in the preparation of the plans and specifications submitted October 9 and related work and discussion with the RWQCB permitting unit, and we are not able to extend this contract again.
