National Secondary Drinking Water Regulations: Drinking water standards are regulations that EPA sets to control the level of contaminants in the nation's drinking water. These standards are part of the Safe Drinking Water Act's "multiple barrier" approach to drinking water protection, which includes assessing and protecting drinking water sources; protecting wells and collection systems; making sure water is treated by qualified operators; ensuring the integrity of distribution systems; and making information available to the public on the quality of their drinking water. With the involvement of EPA, states, tribes, drinking water utilities, communities and citizens, these multiple barriers ensure that tap water in the United States and territories is safe to drink.
Fats, Oils and Grease (FOG) Ordinance: The Illinois Environmental Protection Agency (IEPA) oversees and enforces regulations when a sanitary sewer overflow occurs. Fats, Oils and Grease are a major contributor of sanitary sewer overflows when they build up in the sanitary sewer. A sanitary sewer overflow is defined as the discharge of untreated sewage from the sanitary sewer collection system to a surface water and/or ground. Click Here for the Municipal Code Ordinance
