<br />3.0 WASTE MANAGEMENT WORKPLAN
<br />
<br />As indicated earlier in this report, the waste management work related to WU1 at the site is a
<br />component of the clean closure activities for the subject parcel. An element of the approved Clean
<br />Closure Plan is an Excavation and Material Management Plan (EMMP) that was prepared by our
<br />firm. The EMMP presented measures and procedures for the removal, management, sampling,
<br />testing, and evaluation of residual solid waste materials within WU1.7 Our firm prepared an
<br />Addendum to the EMMP dated March 22, 2018 to slightly revise the verification soil sampling
<br />program (testing of soils beneath the area of removed wastes) as suggested by the Central Valley
<br />Regional Water Quality Control Board (CVRWQCB).8 The EMMP and the Addendum were
<br />approved by the oversight agencies prior to implementation of the work.
<br />
<br />
<br />4.0 WU1 WASTE EXCAVATION, STOCKPILING, SAMPLING/TESTING, AND
<br />EVALUATION
<br />
<br />4.1 General
<br />
<br />Excavation, removal, and stockpiling of waste materials and associated soil within WU1 (capped
<br />area within the northwesterly portion of the subject parcel) was performed in April 2018 by Ramcon
<br />Engineering and Environmental Contracting. The work was overseen by a Certified Engineering
<br />Geologist from our firm; additionally, representatives of SJCEHD, the CVRWQCB, and CalRecycle
<br />observed the work. The work was performed in accordance with the referenced, agency-approved
<br />EMMP and associated Addendum.
