<br />05/19/2022 Referred complaint to Travis L. Flora (Senior Hazardous Materials Specialist) at
<br />(408) 918-3486 (travis.flora@cep.sccgov.org) regarding contaminated soil coming
<br />from Santa Clara County (589 W. Fremont Avenue, Sunnyvale) and being
<br />disposed to the land. Received call back from Travis Flora and he said that the
<br />values for TPH-motor oil and TPH-diesel are so low that they are not a concern.
<br />The soil is non-hazardous so there wouldn't be any reason why it couldn't be used
<br />in this project. He said that he is unaware of any regulations that would prevent
<br />the soil from being used this way and that it is typical in his county. He also said
<br />that since the site that the soil is coming from is a closed clean-up site there isn't
<br />any concern there either. He would only be concerned if it was coming from an
<br />active clean-up site.
<br />Wrote referral letter to DTSC and Water Board.
<br />BAKER
<br />Returned call to Hardeep Singh (209-640-1000). He said he has stopped all
<br />additional truck loads of dirt until questions are resolved. Chains have been put up
<br />to block entry and two guards are on site to prevent any dumping. Tracy Paving
<br />and Grading is the company that was hired to bring in the dirt.
<br />05/23/2022 Scanned file for referral. BAKER
<br />06/06/2022 Referred complaint to Holly Young (Waterboards) at BAKER
<br />Holly.Young@Waterboards.ca.gov.
<br />Abated complaint as 07-Referred to other agency. Turned in file to Lead Sr.
<br />REHS for review.
