1 The City of Everett The Floyd & Snider Team Everett Landfill/Tire Fire Site ' 5.1 OBJECTIVES 1 1 1 1 1 r< P---, 1 1 1 1 1 1 1 5.0 Direct Contact Pathway Site inspections will ensure teat performance and remedial action objectives for the direct contact pathway are met throughout the undeveloped site, during phased construction activities, and after development is in place. Special requirements for construction must also be met. The following performance objectives were originally described in the Final Feasibility Study and Phase // Remedial Investigation (ERM Northwest, 1993). 1. Prevent public contact with landfill materials. In this case, the public is defined as any individual not trained in health and safety precautions, and not associated with construction or maintenance activities at the site. 2. Control vector and nuisance conditions, such as human pathogen vectors and exposed refuse. The remedial action objectives for the direct contact exposure pathway are as follows: • Isolate humans and wildlife from refuse and contaminated material under existing site conditions. • Prevent penetration of the site cover by site users who are not trained in health and safety requirements for contaminated material. • Maintain integrity of site cover, prevent exposure of buried materials by erosion. • Prevent exposure to personnel who are not trained in health and safety requirements for contaminated material during future construction activities. • Prevent exposure to personnel who are not trained in health and safety requirements for contaminated material during future maintenance of site utilities. • Prevent casual exposure to humans and wildlife after redevelopment. • Take precautions when refuse is uncovered, dag up, and disposed of during site development Existing conditions of a minimum two -foot cover of clean soil, positive drainage, and access controls to undeveloped portions of the site will be maintained until potential future development can implement the preferred alternative for future conditions in a phased manner. 5.2 INSPECTION PLAN Inspections of the entire Landfill/Tire Fire Site will occur on a quarterly basis. The objective of the inspection is to identify and record areas of the cap/cover and site security that have been compromised and require repair. Also included are site inspections for the groundwater pathway required to verify that stormwater is prevented from infiltrating the site and that the leachate collection system is in good repair (see Section 4.3).
