<br />Murphy Parkway Property Waste Materials Reuse Workplan
<br />
<br />and evaluation of residual solid waste materials within WU1.2 Our firm prepared Addendum to
<br />the EMMP dated March 22, 2018 to slightly revise the verification soil sampling program
<br />(testing of soils beneath the area of removed wastes) as suggested by the Central Valley Regional
<br />Water Quality Control Board (CVRWQCB).3
<br />
<br />This Workplan includes: a general description of the site; background information; a description
<br />of the planned site development; information, laboratory data and discussion pertaining to
<br />stockpiled materials generated during the recent removal of solid waste materials from WU1;
<br />justification for onsite reuse of materials excavated from WU1; procedures for the reuse of these
<br />materials in onsite engineered fills; and verification/reporting procedures to ensure that the
<br />materials are reused in the manner described herein.
<br />
<br />Our firm prepared a draft version of this Workplan dated May 7, 2018.4 The San Joaquin
<br />County Environmental Health Department (SJCEHD) indicated approval of the draft Workplan
<br />in a letter dated May 11, 2018.5 The CVRWQCB prepared a review letter dated May 11, 2018
<br />indicating conditional approval of the draft Workplan, and we prepared a final Workplan dated
<br />May 18, 2018 addressing comments and requirements presented in the CVRWQCB review
<br />letter.6 7 The CVRWQCB presented a few additional review comments in an email dated May
<br />23, 2018; this revised final Workplan addresses those comments.
<br />
<br />A Vicinity Map showing the location of the subject parcel is presented as Plate 1. A Site Map is
<br />presented as Plate 2 showing the layout of the entire parcel, the former area of capped wastes
<br />(WU1) on the far northwesterly portion of the site, the locations of stockpiled materials that were
<br />recently excavated and removed from the capped waste area, and the general layout of the
<br />planned large commercial/light-industrial building on the property. A detail map showing WU1
<br />area and the locations of verification soil samples collected beneath the area of removed wastes
<br />is presented as Plate 3. A civil engineering drawing depicting additional details pertaining to the
<br />planned construction is presented as Plate 4. Plate 5 is a site map that shows planned waste reuse
<br />areas (beneath the building and concrete pavements). Analytical laboratory data for samples of
<br />the stockpiled materials from WU1, as well as for the verification soil samples collected beneath
<br />WU1, are presented on Tables I through VII; the laboratory reports and chain-of-custody
<br />documentation are included in Appendix A. The Foundation Investigation (geotechnical
<br />engineering report) and a related Clarification Letter for the site development project is
<br />presented in Appendix B.
