OER2 Webinars

Overview

The Naval Facilities Engineering Command (NAVFAC) has developed the Open Environmental Restoration Resources (OER2) webinar series for enhanced information sharing with the Environmental Restoration Program (ERP) community.

Process

The OER2 webinar series is open to the public. The topics are selected for their relevance to Department of the Navy (DON) Remedial Project Managers (RPMs), contractors, and other remediation practitioners that can benefit from learning more about key topics and focus areas for the DON ERP. The objective of the OER2 webinar series is to enhance information sharing and will help participants to:

Obtain the latest information about Department of Defense (DoD) and DON policies and guidance,
Hear about the latest tools, technologies and practices to improve the DON ERP’s efficiency,
Promote innovation and share lessons learned among the DON ERP community, and
Provide feedback to the DON ERP leadership.
