Applying for an aquatic plant management permit
The Legislature directed the DNR to charge fees for APM permit applications to recover the cost of administering the program. Application fees depend on the kind of control you are doing but generally will run about $35. If you apply for two or more treatment types only the largest fee will apply. Do not send your application fee until you have received an invoice from MPARS.
