Section 160.204 would require persons requesting to except a provision of state law from preemption under § 160.203(a) to submit a written request, that meets the requirements of this section, to the Secretary to except a provision of state law from preemption under § 160.203. The burden associated with these requirements is the time and effort necessary for a state to prepare and submit the written request for an exception determination to the Secretary for approval. On an annual basis it is estimated that it will take 40 states 16 hours each to prepare and submit a request. The total annual burden associated with this requirement is 640 hours. The Department solicits public comment on the number of requests and hours for others likely to submit requests.
