Iowa Admin. Code r. 111-3.10
3.10(2) Categories exempt. The following narrowly tailored categories of rules are exempted from the usual public notice and participation requirements because those requirements are unnecessary, impracticable, or contrary to the public interest with respect to each and every member of the defined class:
Rules which are mandated by federal law or regulation are exempted from the usual public notice and public participation requirements in any situation where the commission has no option but to adopt specified rules or where federal funding is contingent upon the adoption of the rules. Notice and public participation would be unnecessary since the provisions of the law or regulation must be adopted in order to maintain federal funding and the commission would have no option in the rule which was adopted.
