Rules, Part 8420.0520 through .0550 shall be made following the same procedures as for conditional use permits, plus the additional notice and time requirements of Minn. Rules, Part 8420.0230. If the amount of wetland to be drained or filled is less than one-tenth of an acre, the sequencing determination under Minn. Rules, Part 8420.0520 shall be made by the zoning administrator.
3.
Monitoring. The zoning administrator shall assure that the replacement plan monitoring and enforcement requirements of Minn. Rules, Part 8420.0600 through .0630 are fulfilled.

All WECS and accessory facilities, including the foundation, shall be completely decommissioned within one year of the discontinuation of use.
x.
Each WECS shall have a decommissioning plan outlining the anticipated means and cost of removing WECS at the end of their serviceable life or upon becoming a discontinued use. The cost estimates shall be made by a competent party; such as a professional engineer, a contractor capable of decommissioning, or a person with suitable expertise or experience with decommissioning.

xxiii.
Meteorological towers shall not exist in one location for more than 18 months. The location of a meteorological tower shall not be considered to have moved unless the meteorological tower shall have moved at least 1,000 feet from its prior location.
xxiv.
Should a WECS not be decommissioned as required herein, the city shall have the right to enter upon the land where the WECS is located for the purpose of decommissioning the WECS. The cost of decommissioning shall be the responsibility of the owner of the land where the WECS is located and the owner of the WECS, jointly and severally. Should either or both fail to pay the city the cost the city incurred in decommissioning the WECS, the city may then spread the charges against the real property benefited as a special assessment under the authority of Minn. Stat. 429.101, as it may be amended from time to time, and other pertinent statutes for certification to the county auditor for collection along with current taxes the following year or in annual installments, not exceeding 10, as the city may determine in each case.
