Past Involvement Opportunities

GLMRIS Report Comment Period

The GLMRIS Team invited the public to comment on the alternatives presented in the GLMRIS Report. Comments were received through March 31, 2014, via public meetings, electronic submittal on the GLMRIS Web site, mail and hand-delivery. Please refer to the GLMRIS Report page for public meeting locations, meeting transcripts, and videos.

Focus Area 2 Other Aquatic Pathways Comment Period

Interim reports for 18 potential aquatic pathways, as well as a summary report, were released beginning September 14, 2012. The GLMRIS FA2 Team asked for public input on these reports. Each report had a 30-day comment period following its release. Read the reports with incorporated feedback on the FA2 Other Aquatic Pathways page.

ANS Control Screening Comment Period

USACE has screened the ANS Controls identified in the Inventory of Available Controls for Aquatic Nuisance Species of Concern – Chicago Area Waterway System (ANS Control Paper) and removed certain controls from further consideration by GLMRIS. USACE requested comments from public stakeholders regarding the ANS Controls Screening from January 18 through February 21, 2013. USACE considered the information generated during the comment period to further screen the list of ANS Controls. More information on the screening can be found on the ANS Control Screening page.

ANS Control Comment Period

USACE asked interested members of the public to review the list of potential Controls contained in the Inventory of Available Controls for Aquatic Nuisance Species of Concern – Chicago Area Waterway System and provide information regarding Controls that may be effective but not included in the paper or comments regarding Controls listed in the paper. Comments were received via electronic submittal through the GLMRIS Web site and mail. The comment period ran from December 21, 2011 through February 17, 2012. USACE reviewed and incorporated public input before finalizing and re-issuing the paper. View these Controls and the updated paper on the ANS Controls page.

Thank you to everyone who took the time to read the paper and to comment. The GLMRIS Team appreciates your input!

NEPA Public Scoping

The National Environmental Policy Act (NEPA) scoping period was from November 16, 2010 through March 31, 2011. For more information regarding NEPA scoping, see What is NEPA Scoping?

During the scoping period, USACE solicited public comments regarding the scope of GLMRIS. Comments were delivered during 12 USACE-hosted public scoping meetings and received via electronic submittal through the GLMRIS Web site, mail and hand-delivery.

Please refer to the Completed NEPA Public Scoping Meetings and Transcripts page for more information regarding these meetings and to view transcripts of the scoping meetings.

The comments received during the scoping period are available on the View Scoping Comments page. A summary of the NEPA public scoping activities and the comments submitted during the scoping period is available in the NEPA Scoping Summary Report (PDF, 1.4 MB).
