LFR Inc. period or at the end of the shortened time frame, the Trust will present the Phase V IRA Detailed Plan to the Court for approval as an Agreed Order modifying the Amended First Final Consent Decree. As required by Section XI.A.4 of the Amended First Final Consent Decree, timely objections to the Proposed Phase V IRA Detailed Plan will be in the form of a petition for Dispute Resolution and will be resolved pursuant to Section XXI of the Amended First Final Consent Decree. 5.2 Contractor Selection and Mobilization Upon final approval of the Proposed Phase V IRA Detailed Plan and design, a group of qualified drillers and substrate vendors will prepare bids to install the wells and provide the substrate for injection. LFR will conduct a site walk with the potential contractors as part of the submittal to allow these parties to view the existing conditions at and features of the Site. Contractors will submit sealed bids to LFR within one month of the site walk. The winning contractor will be selected within two weeks of LFR's receipt of the bids. The selected contractor will then begin preparing plans, purchasing equipment, and obtaining the appropriate permits required to perform the work. LFR will conduct a preconstruction meeting with personnel from the construction contractor and LPL to formulate a construction plan that specifies details such as sequencing the work, the location of material staging areas and waste storage areas, suitable working hours for specific tasks, and notification and chain-of-command procedures. These procedures will be consistent with the precedents established during the Phase I IRA. 5.3 Well Installation LFR anticipates that drilling and construction of the 22 ERD injection wells and six groundwater monitoring wells will occur during a one- to two-month period, access conditions and weather permitting. The wells would be completed at the existing ground surface and will be contained in flush-mounted well boxes to prevent damage to the wellheads and to allow parking and traffic flow in these areas. 5.4 Well Installation and Substrate Injection Construction of the Phase V IRA components will include activities such as well drilling and substrate injection. As with previous IRAs, LFR anticipates that intrusive work activities, such as drilling, would be performed between the hours of 7 A.m. and 7 P.m. in low-profile areas (e.g., those adjacent to the GWETS). However, intrusive activities in high-profile areas would be performed after business hours to minimize the impact to commercial operations. Substrate injection and groundwater sampling is not considered an intrusive activity. Substrate injection would typically involve a pickup truck with a trailer and should not affect traffic or noise.
