D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project has been designed to avoid significant permanent dredge or fill impacts to wetlands and streams. Impounded water will be removed
within 72 hours via pumping to a settling pond. The proposed action at this location will primarily include minor permanent impacts to intermittent
stream channels and herbaceous/shrubby wetlands.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to wetlands and streams will be minimized during pumping activities. Access will be through uplands, via adjacent roadways. Best
Management Practices will be used during pumping activities.
