The remainder of the Site consists of a parking area (asphalt millings) and some grass covered areas.

The Site will be subject to the following key remedial actions: the submittal and approval of a Remedial Action Work Plan (RAWP), development and compliance with the Contaminated Materials Management Plan (CMMP), placement of at least one foot of clean fill or impervious material (e.g. buildings, asphalt, or concrete) over impacted areas to restrict access to underlying soil, implementation of a site-specific Long-Term Stewardship (LTS) Plan, recording of an Environmental Covenant that restricts the Site use to non-residential, ensures there is no interference with the remedy, restricts groundwater withdrawal and ensures compliance with the LTS Plan and CMMP, and the submittal of a Remedial Action Completion Report.
