Certification for Inspection and Maintenance of Stormwater BMPs

Municipalities that are regulated under Maine's Municipal Separate Stormwater Sewer Systems (MS4) program require that the person who conducts post-construction inspections of Stormwater Best Mangement Practices (BMPs) at the facilities in their town be qualified as a Post-Construction Stormwater Inspector. Unless in possession of a degree in engineering or natural resources or with experience with stormwater management in the State of Maine, successfully completing the DEP test on inspecting and maintaining stormwater BMPs is necessary. More information and the test is found in the following file:

• Stormwater BMP inspector test and answer sheet

Five-year Recertification for Long-Term Maintenance of Stormwater Management Systems

• 5-year recertification form
• Simple long-term maintenance plan
