Because representative samples of the materials cannot be collected, and there was no observed PAH <br /> staining or odor, Pinyon recommends the stockpiles be deemed non-impacted and released for sale to the <br /> public. <br /> Sincerely, <br /> Pinyon Environmental, Inc. <br /> Jeremy Musson <br /> Principal <br /> cc: Scott Clark— Burns, Figa and Will, P.C. <br /> Charlse Kellerman, Butala Sand and Gravel <br /> File Location: https://pi nyonenv I sharepoint.com/sites/VistaDelRioTeam/Shared Documents/Butala S and G/Stockpile Sampling/Visual <br /> Evaluation/Butala Stockpile Observations Documenation 20230623.docx <br /> Mr. Lucas West Page 2 <br /> Environmental Protection Specialist <br />
