Depot Wide Surface and Near Surface Soils, Northern Depot Area site. These ICs should be similar to those presented for the other three sites. 2. Transfer of Ownership - Addendum to Future Development Report, Section 2.4, page 2-1; Section 3.4, page 3-1; Section 4 .4, page 4-1; and Preliminary Institutional Control Slip Pages to Draft Final DDJC-Tracy Remedial Design Work Plan, Section 6.5.2.2, page 6-15; Section 6.5.3.2, page 6-16; and Section 6.5.4.2, page 6-16. Each of these sections explain that if ownership of the Installation is transferred to private or nonfederal entities in the future, restrictive covenants will be written into the land property deed to prevent schools, playgrounds, hospitals, or housing from being built at the sites until contaminants of concern (COCs) are below levels of concern. Assuming that such ownership transfer takes place several years (or even decades) from now, after the Final Closeout Report under CERCLA has been issued (a reasonable assumption) , what MECHANISM exists to remind and trigger those in charge in future years to include such restrictive covenants in the property deed? Although the Base Master Plan may physically exist as a document far into the future and it may continue to identify the need for restrictive covenants for these sites, this does not ensure that those in charge, decades from now, will even remember to refer to those requirements prior to property transfer, due to the elapsed time, changes in personnel, changing Federal priorities, etc. Thus, some administrative or legal mechanism is needed as a reminder/trigger for this action. How will this be accomplished? Also, what mechanism is in place to ensure that sign posting at the IC sites remains in place? 3. SWMU 7 - Addendum to Future Development Report, Section 2.3, page 2-1 The first paragraph states that "The selected remedy specifies that for Buildings 19 and 21 and pavement within the affected area shown in Figures 2-1 and 2-2, the signatory parties to the ROD must be notified at least 90 days before demolition or construction activities that could expose contaminated soil. " Building 15 may also be effected by future development activities. Please add Building 15 to this list (as shown on Figure 2-2) , to be consistent with the Slip Pages to the Remedial Design Work Plan. 4. SWMU 33 - Addendum to Future Development Report, Figure 4-1 Figure 4-1 indicates ICs apply only to about half of the Industrial Waste Pipeline (depicted by red rectangles) . The remaining portions of the IWP are not subject to ICs based on this figure. The reason for this is not clear and appears to conflict with the Final ROD. The ROD (Section 9.8.2.6) states "Any construction, excavation, or demolition along the IWP will require an evaluation of potential impacts to the selected remedy. " ICs provide the mechanism to ensure that such an evaluation is done. The ROD does not distinguish among different segments of the IWP with 2
