The City of Richmond Indiana and Earlham College are in partnership as MS4 entities. This partnership and coordination of all city and EC activities are cost-effective and benefits both Richmond and Earlham College. The college located all stormwater in-lets, designed a map indicator of all stormwater in-lets, and have marked all in-lets with a deca reading “No Dumping-Drains to River”. Earlham keeps records of all road and sidewalk treatment (such as ice melt, salt & sand), debris from in-lets, parking lots, and campus streets, and turf applications (such as fertilizer and herbicide). This is a method that Earlham uses to maintain this idea of sustainability and comply with the City of Richmond Indiana.
