Regulations

In accordance with Section 1-9 of the County Code, the department transmitted regulations to the County Clerk on April 13, 2017  to be effective May 13, 2017.

The Cook County Board passed item 17-0059 (updates, reorganization and modernization of Chapter 30 Environment of the Cook County Code) on April 12, 2017, with an immediate effective date.  Because the enacted ordinance included the deletion of items that are now in regulations, the Department has notified the County Clerk that the submitted regulations will be in effect as emergency regulations to in order to ensure continuous and safe operations.
