Closure in Place Sample Clauses
Closure in Place. The Parties intend that the Ash Landfill, solid waste landfill, specified retention and stormwater ponds, and certain subgrade structures, pipes, and conduit will be closed in place. Closure in place of these facilities and structures, and any others mutually agreed to by the parties in accordance with this Lease, is a permissible use that has been mutually agreed upon by the Parties. The Rental Payments (Section 7 Rental and Rental Payment) are, in part, consideration paid by Lessees for the Nation’s consent to closure in place and the Lease Term is based, in part, on Lessees’ need for access to conduct monitoring and maintenance activities after closure. All closure in place shall comply with this Lease, the Retirement Guidelines, the NGS Retirement Plan, and all applicable federal environmental laws.
Closure in Place. Comm 10 allows closure in place of USTs in a limited number of circumstances. Closure in place must be requested in writing from the Commerce authorized agent responsible for closure verification. Only written permission for closure in place is valid. Site assessments are still required when tanks are closed in place. Collect soil samples from all of the locations specified above by one of the following methods.
a. Soil borings, through the use of a drill rig, power auger, or hand auger. Conduct the borings within three feet of and below each end of each tank, drilling at an angle if necessary. Conduct soil borings along piping runs and pump islands immediately adjacent to these structures. The borings must be completed, documented and abandoned in compliance with the requirements of ch. NR 141, Wis. Adm. Code, which governs monitoring ▇▇▇▇▇ and soil borings.
b. Holes cut in the bottom of the tank(s). If the tank(s) can be safely entered, and holes can be cut in the bottom, the soil beneath the tank(s) may be sampled through the holes. Cut the holes near each end of each tank. If native soil cannot be accessed from the holes, sample the backfill material. Include visual observations of the interior of the tank in the closure documentation.
c. Test pits beside the tank(s). Many tanks are abandoned in place due to their proximity to building foundations. Often it is possible to excavate a test pit or trench on the side of the tank opposite the foundation. Soil conditions can then be visually assessed and soil samples collected directly.
