Notwithstanding s. 254.11 (intro.) and (9), whenever the centers for disease control and prevention of the federal department of health and human services specifies a standard for the determination of lead poisoning or lead exposure that differs from that specified in s. 254.11 (9), the department shall promulgate a rule defining “lead poisoning or lead exposure” to correspond to the specification of the centers for disease control and prevention. Rules promulgated under this section supersede s. 254.11 (9) with respect to the requirements of this subchapter.
