Illinois SB 1489: Green Infrastructure for Clean Water Act

The Green Infrastructure for Clean Water Act required the Illinois Environmental Protection Agency to adopt comprehensive storm water management rules that meet certain requirements by July 1, 2012. Beginning in 2010, the agency was required to: implement a storm water permit fee program adequate to support the adoption and implementation of State storm water regulations as required by the Act; establish a Statewide standard for storm water management programs in order to transition toward the use of green infrastructure as the predominant storm water management strategy; review its rules on the distribution of money from the Water Revolving Fund; and endeavor to establish new criteria which prioritize the use of green infrastructure in all projects involving storm water management and water efficiency.

In Section 10 of SB 1489, the General Assembly finds that there are a number of potential benefits from the use of green infrastructure including mitigation of and adaptation to impacts of climate change. Green infrastructure strategies help with adaptation to projected climate change impacts, including increased storm intensity, flood potential, and impacts on the quantity of surface and ground water supplies.

(a) The General Assembly finds that: 

(1) urban storm water, when not properly controlled and treated, can cause pollution of the waters of the State, threaten public health, and damage property by carrying pollutants from our highways, streets, roads, parking lots, driveways, sidewalks, alleys, lawns, and other surfaces of low permeability into lake rivers, streams, and ponds;

(2) development can increase storm water runoff by increasing the size and number of paved and other impervious surfaces within a watershed and decreasing the extent of vegetated and other permeable surface areas that control storm water runoff through natural infiltration and evapotranspiration and groundwater recharge;

(3) current urban storm water related threats to the State's water resources include pollution, increased water temperatures, flooding, groundwater depletion, loss of habitat, stream bank erosion, sewer overflows, basement backups, contaminated drinking water sources, and sedimentation of waterways; and

(4) some studies show that preserving and expanding natural and built green infrastructure can minimize negative impacts and enhance the resilience of water infrastructure and water bodies.
