Proposal for <br />Various Environmental Services <br />Page 29 <br />August 1, 2022 <br />Key Personnel: Mr. Williams was the HazMat Survey lead, Mr. Sandoval was the site investigation and <br />assessment lead, and Mr. Ward was the CIH for this project. <br />Type: Category I <br />Client: City of Alhambra <br />Project Involvement: 2018-2019 <br />Disclaimer: Mr. Toosi was the deputy manager and <br />senior engineer of this project at his previous role as <br />the vice president of Rubicon Engineering <br />Corporation. <br />Project Description: Five USTs containing gasoline <br />and waste oil were removed from the City of <br />Alhambra's Maintenance Yard in the 1990s. However, the soil in the area was not evaluated for the <br />presence of residual contamination. The LA Water Board on April 20, 2018, sent a Corrective Order <br />Letter to the City. That order requested additional assessments to be conducted and a work plan for these <br />activities must have been submitted to the LA Water Board by May 20, 2018. Our team was contacted by <br />the City's Utility Department's Deputy Director, Mr. David Dolphin, to initiate developing the work plan <br />and submit to the agency by the requested deadline. The LA Water Board approved our work plan and <br />requested the results of the investigation in a technical report format by October 13, 2018. We completed <br />all pre -field activities and hired subcontractors that we felt were the most qualified while offering the best <br />value and mobilized our field crew on October 1, 2019. For this project, our team: <br />■ Drilled a total of 12 borings using direct push technology (DPT) to a depth of 35 feet below <br />ground surface and collected samples at every five-foot interval. <br />■ Analyzed the samples using a mobile laboratory subcontractor for total petroleum hydrocarbons <br />(TPH) and volatile organic compounds; and <br />Showed, based on the results of this investigation, that the removal of the USTs was conducted <br />properly, and that no residual contamination was present at the site. On October 12, 2018, we <br />Submitted the final Site Closure Report and requested closure for the site from the LA Water <br />Board. On October 7, 2019, the Water Board issued a no further -action letter and approved our <br />request for Site Closure. The city was delighted with our team's efforts to finish this project <br />within the budget in a timely manner. We have established relationship with the LA Water Board's <br />staff and have a reputation as a diligent consultant, whose mission is to protect the environment and <br />ensure its clients are not environmentally liable. <br />Key Personnel: Mr. Toosi was the deputy project manager and senior engineer for this project. <br />0 A -Tech Consulting, Inc. <br />
