The Chicago District regulates certain activities conducted in waterways and wetlands located within Cook, DuPage, Lake, Kane, McHenry and Will Counties in northeastern Illinois, as well as Lake, Porter and a portion of LaPorte County in northwestern Indiana. Part of the Corps' regulatory responsibility involves ensuring that permittees comply with issued permits (compliance), as well as ensuring that unauthorized activities do not take place in jurisdictional areas (enforcement).
Failure to obtain a Department of the Army authorization for work conducted within waters of the United States (including wetlands), or failure to comply with the terms and conditions of a Department of the Army Permit, will result in an enforcement action being brought by the Corps of Engineers. Resolution options include, but are not limited to, restoration of the destroyed wetland area, approval of an after-the-fact permit application, or in appropriate cases, referral to the U. S. Environmental Protection Agency (USEPA) or the U. S. Attorney for criminal or civil action.
To report a suspected violation of Corps regulatory requirements, contact the Chicago District Regulatory Branch at (312) 846-5530. Alternatively, you may complete and return a Report of Unauthorized Activity Form to the Branch. If you wish to remain anonymous, please state this in your communication. In either case, please provide a telephone number or e-mail address through which we may contact you should we require additional information. Please fill out the form with as much information possible. You can submit it through the mail, fax or to our e-mail address. If you are able to include photos showing the suspected violation, that could help us with our investigation.
