GLMRIS: Great Lakes and Mississippi River Interbasin Study
December 21, 2011

ANS Control Paper Release & Comment Period

The U.S. Army Corps of Engineers released today, Dec. 21, the Inventory of Available Controls for Aquatic Nuisance Species (ANS) of Concern – Chicago Area Waterway System (CAWS), (PDF, 2.3 MB) an Interim Product of the Great Lakes and Mississippi River Interbasin Study (GLMRIS).

This paper identifies available options or technologies (ANS Controls) that may be effective at preventing the 39 ANS of Concern, as identified in the ANS White Paper released in July 2011, from transferring through the aquatic pathways in the CAWS, as well as other potential aquatic pathways.

The paper is posted, along with ANS Control Fact Sheets and the ANS Control Comment Period details on the new ANS Control Paper page.

It is important to note that the ANS Control Paper is intended to inventory available ANS Controls. It does not contain specific recommendations, rank the effectiveness of the Controls, or identify constraints, impacts, regulatory requirements or technological feasibility of application.

USACE is announcing an ANS Control comment period that begins on Dec. 21, 2011, and ends on Feb. 17, 2012. USACE is asking the public to submit: i) information on ANS Controls that may be effective at preventing the transfer of ANS of Concern but are not included in the paper, or ii) comments regarding ANS Controls identified in the paper.

USACE is hosting two conference calls for interested members of the public to ask questions about the paper. The calls will be held on Jan. 10, 2012 from 2 – 4 p.m. (CST) and Feb. 8, 2012 from 10 a.m. – noon (CST). Call-in information for both calls is:
