Illinois Environmental Protection Agency responsiveness summary for : Sugar Creek Impoundment : Section 401 water quality certification for the construction of a water supply reservoir for the city of Marion.

The city of Marion has applied to the Illinois EPA for Section 401 water quality certification to construct a 1,172 surface acre, raw water impoundment reservoir on Sugar Creek, southeast of Creal Springs, Williamson County, Illinois. This proposal and the impacts are described in the Final EIS, DSI, and DSII. The proposed project will involve the construction of a reservoir on Sugar Creek and the mitigation for affected wetlands and jurisdictional waters of the United States.

Dimensional change behavior of caribbean pine using an environmental scanning electron microscope

Moisture transport and dimensional change during wood drying or wetting processes were analyzed based on pictures from an environmental scanning electron microscope (ESEM). This provides quantitative relationships between dimensional changes of total area, cell wall, and lumen, and moisture content for earlywood and latewood. Earlywood and latewood behave similarly but show some quantitative differences. The overall outcome for sections containing both kinds of wood seems to be dominated by the latewood behavior. The observed strain behavior of wood during drying is anisotropic in ways that are inconsistent with explanations solely related to microfibril orientation or earlywood/latewood interactions and more likely may be influenced by ray tracheids.
