Little Canada Zoning Code Stormwater Management 928-21 APPENDIX A. SPECIAL WATERS A. GENERAL REQUIREMENTS All requirements in this Appendix are in addition to BMPs already specified in the permit. Where provisions of Appendix A conflict with requirements elsewhere in the permit the provisions in Appendix A take precedence. All BMPs used to comply with this Appendix must be documented in the SWPPP for the project. If the terms and conditions of this Appendix cannot be met, an individual permit will be required in accordance with Minn. R. ch. 7001. B. REQUIREMENTS FOR DISCHARGING TO WETLANDS If the project has any storm water discharges with the potential for significant adverse impacts to a wetland (e.g., conversion of a natural wetland to a storm water pond) , the Permittee(s) must demonstrate that the wetland mitigative sequence has been followed in accordance with D.1 or D.2 of this appendix. 1. If the potential adverse impacts to a wetland on a specific project site have been addressed by permits or other approvals from an official statewide program (U.S. Army Corps of Engineers 404 program, Minnesota Department of Natural Resources, or the State of Minnesota Wetland Conservation Act) that are issued specifically for the project and project site, the Permittee may use the permit or other determination issued by these agencies to show that the potential adverse impacts have been addressed. For the purposes of this permit, deminimus actions are determinations by the permitting agency that address the project impacts, whereas a non-jurisdictional determination does not address project impacts. 2. If there are impacts from the project that are not addressed in one of the permits or other determinations discussed in Appendix A, Part D.1 (e.g., permanent inundation or flooding of the wetland, significant degradation of water quality, excavation, filling, draining), the Permittee must minimize all adverse impacts to wetlands by utilizing appropriate measures. Measures used must be based on the nature of the wetland, its vegetative City types and the established hydrology. These measures include in order of preference: a. Avoid all significant adverse impacts to wetlands from the project and post project discharge. b. Minimize any unavoidable impacts from the project and post project discharge. c. Provide compensatory mitigation when the Permittee determines that there is no reasonable and practicable alternative to having a significant adverse impact on a wetland. For compensatory mitigation, wetland restoration or creation shall be of the same type, size and whenever reasonable and practicable in the same watershed as the impacted wetland.
