3i. Comments:
Salem Creek - No excavation would occur in the stream bed. However, excavation is required to remove batteries from the stream bank. Some
excavation of the UT to Salem Creek stream bed and banks will occur to remove batteries. The impacts in this PCN represent a worse -case scenario.
Excavation will be limited to the greatest extent practicable during the remediation effort. Appropriate stream bank stabilization measures and natural
channel design features (e.g., rock vanes) will be implemented to minimize impacts from sediment and erosion

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Lead battery contamination was detected in the stream and stream bank sods. Given the nature of the project activity, no avoidance or minimization
measures are provided, beyond those described below that can occur during the project excavation phase.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The impacts in this PCN represent a worse -case scenario. Excavation will be limited to the greatest extent practicable as determined by on -site soil
testing during the project excavation phase. Streams will be restored to their pre - existing condition, and appropriate stream bank stabilization
measures and natural channel design features (e.g., rock vanes) will be implemented to minimize impacts from sediment and erosion.
