Discharge Permits

Pursuant to the provisions of all applicable ordinances of the District, an Industrial User (IU) discharging into the sanitary sewer is considered a Significant Industrial User (SIU) and MUST apply for a Wastewater Permit if any of the following conditions are met:

  1. The user has a discharge of process flow of 25,000 gallons or more per average work day.
  2. The user has a discharge flow greater than 5% of the flow in the District’s wastewater treatment system.
  3. The user’s wastewater contains toxic pollutants as defined pursuant to Section 307 of the Act or State Statutes and Rules.
  4. District, IEPA, or USEPA finds the user’s wastewater has significant impact, either singly or in combination with other contributing industries, on the wastewater treatment system, the quality of sludge, the system’s effluent quality, or air emissions generated by the system.
  5. The user is a member of a National Categorical Pretreatment Standard promulgated by the USEPA in accordance with Section 307 (b) and (c) of the Act and 40 CFR, Section 403.5 which applies to industrial users. For purposes of this section, “process wastewater” excludes sanitary, non-contact cooling water, and boiler blow down wastewater.

Pretreatment Program

The Clean Water Act of 1972 called for a national pretreatment program to control industrial discharges into public sewage systems. These programs are necessary to prevent serious problems that can occur from the discharge of toxic industrial pollutants. Industrial Waste Surveillance (IWS) operates a Federally approved pretreatment program to implement the federal standards and protect the District’s collection system and treatment facilities.

Pretreatment Program Modifications

In February 2008, the USEPA approved changes to the District’s Industrial Pretreatment Program.  These changes incorporated new Federal Pretreatment Regulations and revised local limits. The District is required to establish local discharge limits to industry in order to protect the treatment plant and sustain environmental criteria.  The report discusses the development of these local limits and is available below:

The District’s Pretreatment Program contains the following elements to assure a successful program:

  • Administrative Core: Legal authority, professional staff, funding, and information based on local industry;
  • Discharge Standards: Industrial effluent limits based on federal standards and local limitations determined to protect the system;
  • Implementation Activities: Permit administration, notification, inspection, monitoring, and enforcement;
  • Information System: Data management and public access to information.

Industrial Commercial Sampling

IWS sample technicians retrieve wastewater samples from District industrial/commercial customers. These samples are used to ensure that companies adhere to all pertinent regulations and laws. In addition, these samples are used to determine Wastewater Characteristics (WWC’s) that are used to calculate the amount charged to a company. To contact IWS, call 815-387-7636 or e-mail Industrial Waste Surveillance.

Accidental Discharge/Spills

The IWS Department also coordinates the District’s response to toxic chemical spills by an Industrial User (IU) that could invade the sanitary sewers. In case of an accidental or deliberate discharge to the sanitary sewer, the IU must notify the District immediately. To report a spill, call 815-38-SPILL (815-387-7455) any time (24 hours a day, 365 days a year).

The following downloadable form must be completed and returned to the District Director within five (5) days following the incident.  Completion of this form is a requirement of District Code of Ordinances (Title 2, Article II, Section 7, A.3.) and does not relieve the IU of any liabilities as a result of the discharge. Prompt and accurate reporting also reflects that the user is attempting to address the problem.

Hazardous Waste Notification, 40 CFR Part 403.12

The following document gives a brief definition of hazardous waste. It is intended to only be used as a guideline. The District recommends that all industrial users who think they may discharge a hazardous waste obtain a complete copy of 40 CFR Part 261. Definition of Hazardous Waste.

As a result of the USEPA General Pretreatment Regulations, industrial users are required to notify the Publicly Owned Treatment Works (POTW), in this case, the District, the EPA Regional Waste Management Division Director, and the State hazardous waste authorities, in writing, of any discharge into the sanitary sewer of a substance that, if otherwise disposed of, would be a hazardous waste as defined in 40 CFR Part 261.  Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge, i.e., continuous, batch or other.  If the industrial user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification shall also contain certain information regarding the hazardous waste discharged.

Notification is required only once for each hazardous waste discharged.  However, notifications of changed discharges must be submitted under 40 CFR 403.12(j).  The notification requirement in this section does not apply to pollutants already reported under the self-monitoring requirements of 40 CFR 403.12(b), (d), and (e).

A copy of this report Hazardous Waste Notification Form also needs to be sent to the USEPA Regional Waste Management Director and the IEPA Waste Management Authorities at the addresses below:
