7.0 Introduction<br />

This Remedial Action Work Plan (lWIVP) describes the methods and procedures to execute and<br />

accomplish the remedial work involved with the Fort Ord Operable Unit 2 (OU2) Landfill<br />

Closure. The permanent remedial work consists of demolition, well abandonment, excavation of<br />

refuse, landfill cover construction, revegetation of the work areas, and restoration of roads and<br />

sidewalks. Temporary needs for closure include traffic control, construction support facilities,<br />

security, safety, and utility services. This RAWP also considers the needs for environmental<br />

protection, health and safety, and community relations.<br />

The USACE, through the Total Environmental Restoration Contract (TERC), is constructing the<br />

landfill cap in accordance with approved documents including the Record of Decision (ROD)<br />

and the Harding Lawson Associates (HLA) design. TERC employs a designhuild mechanism<br />

to perform the remedial work. This mechanism allows latitude for the contractor, IT Corporation<br />

(IT), to suggest time and cost-saving measures and improvements without compromising the<br />

intent of the ROD, the design, or the quality of the work. The lWWP includes these time and<br />

cost-saving measures as constructibility improvements for consideration by the United States<br />

Army Corps of Engineers (USACE) and regulatory agencies.<br />

IT is incorporating these constructibility improvements to the HLA design, which is the base<br />

document, in this RAWP. These improvements enhance the overall design approved by the Base<br />

Cleanup Team (BCT) and are meant to define those areas which deviate from the approved<br />

design. BCT approval is requested to adapt these improvements to the approved design.<br />

These improvements do not change the basic design concepts and performance specifications<br />

approved in the HLA design documents. The design consists of capped landfill areas within a<br />

low permeable liner and vegetative cover. Therefore, no Explanation of Significant Differences<br />

(ESD) amendments are required to the ROD based on these constructibility improvements, The<br />

only ESD requirement, which adds cleanup criteria to the ~eas to be consolidated, is currently<br />

undergoing review by the United States Environmental Protection Agency (USEPA),<br />

Department of Toxic Substances Control (DTSC), California Integrated Waste Management<br />

Board (CIWMB), and Regional Water Quality Control Board (RWQCB).<br />
