Iowa Admin. Code r. 27-60.30
60.30(4) Valid registration. A registration is valid only if approved by the division and acknowledged by a registration certificate signed by the division administrator, listing site name, location, and operator to which the site is registered.
Failure to fulfill the requirements of this rule or chapter may result in the invalidation of a site registration following notification to the operator by the division.
The division may request additional information or materials to further distinguish a site from other sites.
A single registration shall consist of contiguous describable tracts of land which can be enclosed by a single unbroken boundary line and including only that property upon which the operator has a legal right to conduct mining.
