Industrial Storm Water Program
As a result of the federal regulations governing storm water discharges, the State of Michigan began issuing permit coverage in 1994. There are three types of permits available in Michigan: a general permit, a general permit with monitoring requirements, or a site specific individual permit. There are approximately 4,000 facilities with storm water discharge authorization.
Michigan's industrial storm water permit authorization requires facilities to obtain an industrial storm water certified operator who has supervision over the storm water treatment and control measures at the facility. In addition the facility must develop a Storm Water Pollution Prevention Plan (SWPPP) which describes nonstructural and structural controls implemented onsite and eliminate any unauthorized non-storm water discharges. The certification process for industrial storm water certified operators is currently an on going process in each of the district offices.

Industrial Storm Water Certified Operator Training Options and Information
All facilities that require industrial storm water permit coverage are required to have an Industrial Storm Water Certified Operator who has supervision over the facility's storm water treatment and control measures. The information below discusses how to become a new certified operator and how current certified operators can renew their certification that is due to expire:
- New Certified Operator Information: In order to obtain a new certification, you typically must attend one of the EGLE WRD industrial storm water certified operator training/exam sessions which are conducted in the various district offices. However, given the situation regarding COVID-19 it has been decided to suspend all "in person" training/exam sessions until at least January 1, 2021. An application form which includes self-study materials and an exam is available for those looking to become an Industrial Storm Water Certified Operator until "in person" trainings can resume. To apply for a certification, a complete application/exam form needs to be submitted to EGLE WRD along with the $30 certification fee. If you submit a complete application, pass the exam with at least a 70%, and pay the $30 certification fee you will be issued a certification that is valid for 5 years.
- Certification Renewal Information: Certified operators will receive notice from EGLE WRD when their certification is due to expire and are typically required to attend a recertification training session if they wish to renew their certification. However, due to the COVID-19 situation all the "in person" training sessions required for operators looking to renew their certification that is due to expire on July 1, 2020 have been cancelled. To account for the cancelled training sessions, a Recertification Form that includes an online training certification component is available for those looking to renew their certifications this year. The online training certification component is intended to satisfy the required training associated with the renewal process. In order to complete the renewal process, a completed Recertification Form and the $95 recertification fee must be submitted to EGLE WRD on or before August 31, 2020.
The Industrial Storm Water Certified Operator Training Manual was developed by EGLE WRD to inform permittees and Industrial Storm Water Certified Operators of the program and permit obligations. The training manual is intended to be utilized as part of the online Industrial Storm Water Certified Operator trainings discussed above.
Certified operators that have forgotten their certification number or certification expiration date can obtain the information from the current list of Industrial Storm Water Certified Operators which is maintained by the Wastewater Operator Certification Program staff.

Storm Water Program Permit Information
The industrial storm water regulations apply to a wide range of industrial and municipal facilities. Facilities will need to consider their primary industrial activity, their industrial exposure, and their storm water discharge when determining if a permit is necessary. If it is determined that an industrial storm water permit is needed, the facility will need to understand the requirements listed in the appropriate permit associated with the applicable Watershed Cycle Year. Storm water permits are issued based on the Watershed Cycle Year schedule and are reissued every 5 years. The information below is intended to help facilities understand the process:
- Determining if a facility is required to obtain a permit
- Primary Activities & Standard Industrial Classification (SIC) Codes
- North American Industry Classification System (NAICS) Website
- (NAICS / SIC code) Frequently asked questions
- Watershed Cycle Year Map

No Exposure Certification Information
This section provides information regarding Michigan's No Exposure Certification which allows regulated facilities to forgo the need to obtain a National Pollutant Discharge Elimination System (NPDES) industrial storm water permit if specific conditions can be met. The No Exposure Certification is applicable to all facilities regulated by the industrial storm water regulations and is the ultimate goal of the storm water program. Facilities that obtain a No Exposure Certification must maintain their condition of no exposure and are required to renew the certification every 5 years. The documents below will provide more detail:

Conducting Visual Assessments of Industrial Storm Water Discharges
Conducting visual assessments of storm water discharges from areas of industrial activity is a new permit requirement for facilities in Michigan with industrial storm water permit coverage under the newly issued general permits and individual permits with storm water coverage. The visual assessment is part of the comprehensive inspection conducted by the Industrial Storm Water Certified Operator at the facility. The following compliance assistance documents, webinars and tutorials have been developed to help facilities better understand this permit requirement.

Benchmark Monitoring Information
In an effort to align with U.S. Environmental Protection Agency (U.S. EPA) storm water regulations, EGLE's Water Resources Division began implementing Benchmark Monitoring requirements in the 2016 storm water permits associated with special use areas. The purpose of Benchmark Monitoring is to provide data to help characterize the quality of the storm water being discharged from facilities within selected industrial sectors which include sectors classified under Standard Industrial Classification (SIC) codes 5015 (Motor Vehicle Parts, Used) and SIC code 5093 (Scrap and Waste Material). Data obtained during the course of the Benchmark Monitoring Study are compared to benchmark concentrations as a means of evaluating the storm water management controls at the facility. Permittees should utilize the assistance documents and videos available in the visual assessment section of this webpage along with the documents below when implementing the Benchmark Monitoring requirements.

Activity Specific Controls
This section is a supplement to the operator training manual. This section of the training looks at some common activities or locations at industrial facilities where specific controls could be used to prevent storm water pollution, store contaminated water or treat contaminated storm water. Activity specific controls are designed to keep the site clean, keep your facility in compliance with the storm water regulations and ultimately to protect the water resources for future generations.
Storm Water Pollution Prevention Plans (SWPPP)
EGLE has created a SWPPP template to assist permittees in the development of an approvable SWPPP. A sample SWPPP is also provided as a reference.
The SWPPP Annual Review Report must be submitted via MiWaters for many permittees though it should be noted that the SWPPP Annual Review Report requirements are changing. Permittees operating under a permit that authorizes the discharge of industrial storm water issued after 4/1/2021 will no longer need to submit a SWPPP Annual Review Report via MiWaters. However, these permittees must still complete a SWPPP Annual Review Report and retain a copy (written or electronic) with the storm water program records onsite for 3 years. Permittees are responsible to review their permit to ensure compliance. For those permittees that do not have to submit the SWPPP Annual Review Report via MiWaters, the document below can be used to meet the related permit requirements.
