The Municipal Separate Storm Sewer System (MS4) Annual Report must be submitted to the MPCA by June 30th of each calendar year, as required by PART IV.B of the MS4 General Permit.

In 2014, the MS4 Annual Report was reformatted to be an online questionnaire, accessible by a login username and password. You must click the 'Submit' button on the final page of the questionnaire to submit your responses to the MPCA. After you submit your MS4 Annual Report, please allow up to three business days to receive a confirmation email from the MPCA.
