8.f)2) Addition-Noise Analysis for the EIS. f � � c'�����/����? � �� -, � Anne Hurlburt From: Knapp, Leslie[Leslie.Knapp@aecom.com] Sent: Tuesday, September 20, 2011 2:01 PM To: Anne Hurlburt Cc: Sherri A. Buss; White, Chris Subject: Out-of-Scope Items Anne, We agreed on our call with you yesterday that we would provide costs to conduct some additional noise analysis for the EIS. �--- 1. Noise impacts along the truck haul routes: • Monitoring ambient noise levels at two locations along the roadways • Modeling of noise impacts at locations along the haul corridor • Data analysis and documentation for EIS 2. Modeling of facility operations noise impacts at a worst case receptor location. The cost for these items should be$7,000 or less. We may want to consider requesting authorization to conduct out-of-scope work as needed address data gaps with a cap of$15,000 or so in case other items come up. We could provide you with a task order cost for each item prior to working on it but would allow for fast turnaround. Let me know if you need more information. Thanks, Leslie Leslie H.
