B. The Consent Decree obligates the City, among other things, to operate and maintain a system of wells and treatment plants known collectively for this Agreement as the "Newmark Facilities," which include, in part, construction and implementation of two operable units: the Newmark Operable Unit (Newmark OU) and the Muscoy Operable Unit (Muscoy OU). The Newmark Facilities are intended to function as a groundwater treatment system to clean up contaminants in a portion of the Bunker Hill Basin. The primary contaminants of concern in that plume are tetrachlorethylene (PCE) and trichloroethylene (TCE). C. Pursuant to the terms of the Consent Decree, the "Work" to be done by the City is defined in the Consent Decree, and includes the operation and maintenance of the Newmark Facilities. The Work is subject to the oversight of both the United States Environmental Protection Agency (USEPA) and the State of California Department of Toxic Substances Control (DTSC), with the lead and support oversight roles divided between the two agencies, depending on the task. City compliance with Consent Decree terms is demonstrated through monitoring of contaminant concentrations as well as a separate compliance measure based on month-to-month water level data, particle tracking and potentiometric surface mapping, as described more fully in Section III.F.2.b) of the Statement of Work (SOW). This month-to-month water level compliance measure is distinct from, and calculated very differently than the long-term measurements of particle movement used in the Groundwater Model discussed below. D. As a condition of the Consent Decree, the City is also obligated to institute a groundwater management and permit program (GMPP) to "ensure the effectiveness and integrity" of the Newmark Site that includes: (i) taking appropriate actions to prevent or mitigate the potential 1082952.1 5104575
