Comment: There are two points made in this summary statement, one is that AGE is light on trench logs and delineation information and the other is related to wastes extending offsite onto an adjacent property. • The final deposition of the waste that was removed from the property. There should be copies of receipts from the disposal sites.All of that information should be included. • Because we do not know for sure what waste[s]are on the neighboring property, gas could be generated by that waste. 1 think that we should have at least one gas well near the waste on the neighboring property. • In the meeting with the potential buyers there was discussion of excavating the area down 5 ft and possible reuse of the material onsite. The EHD needs those details prior to considering this property partially closed. Comments: please refer to Ninyo & Moore comments related to the PCLUP. 1 The email from the LEA stated that it was decided that the LEA would need to be onsite for the planned excavation portion [of work] and that prior to excavation, a Service Request form and required and a work plan for trenching, including safety plan, and a map of proposed trench locations was required. The email provided a brief description of the anticipated earthwork construction activities that will disturb and redistribute soils and wastes during planned site development. It was indicated that the Geotechnical Investigation for the project that included general recommendations for earthwork and over-excavation of fill materials was attached to the email. Brusca Associates, Inc. stated that the Geotechnical Engineer at Raney Geotechnical, Inc., was currently considering the specific nature of the waste/landfill materials beneath the northwesterly portion of the property, and may have some additional recommendations/requirements with respect to those materials. The email stated the following information related to addressing LEA comments to the PCLUP prepared by AGE: Planned Earthwork Activities: "Project earthwork construction will involve the disturbance, redistribution, and grading of soils across esfs]sentially the entire 48-acre parcel, including the landfill area on the northwesterly portion of the site. The project specifications call for the complete excavation of loose soils1fill materials (including remnant buried glass waste) to expose underlying firm, native undisturbed soils. In some areas, the depth of required excavation to remove fills/wastes could be several feet or more. The excavated soils (and mixed-in glass materials) will be moisture conditioned as necessary, and placed and compacted as engineered fill within various project areas (potentially including areas outside of the current landfill footprint). Any deleterious materials encountered other than glass and deemed una[a]ccpetable to the Geotechnfi]cfi]al Engineer(such as piping, rubbish, large metal fragments, etc.) will likely need to d for removal and offsite disposal.
