Removal, demolition and disposal of any of the <br /> above-mentioned chemicals should be conducted in compliance with California <br /> environmental regulations and policies. In addition, sampling near current and/or <br /> former buildings should be conducted in accordance with DTSC's 2006 Interim <br /> Guidance Evaluation of School Sites with Potential Contamination from Lead <br /> Based Paint, Termiticides, and Electrical Transformers <br /> (https•//dtsc ca gov/wpcontent/uploads/sites/31/2018/09/Guidance Lead <br /> Contamination 050118.pdf). <br /> 3. If any projects initiated as part of the proposed project require the importation of <br /> soil to backfill any excavated areas, proper sampling should be conducted to <br /> ensure that the imported soil is free of contamination. DTSC recommends the <br /> imported materials be characterized according to DTSC's 2009 Information <br /> Advisory Clean Imported Fill Material(https://dtsc.ca.gov/wp- <br /> content/uploads/sites/31/2018/09/SMP FS Cleanfill-Schools.pdf). <br /> 4. If any sites included as part of the proposed project have been used for <br /> agricultural, weed abatement or related activities, proper investigation for <br /> organochlorinated pesticides should be discussed in the MND. DTSC <br /> recommends the current and former agricultural lands be evaluated in <br /> accordance with DTSC's 2008 Interim Guidance for Sampling Agricultural <br /> Properties (Third Revision) (https://dtsc.ca.gov/wp- <br /> content/uploads/sites/31/2018/09/Ag-Guidance-Rev-3-August-7-2008-2.pdf). <br /> DTSC appreciates the opportunity to review the MND.
