b) This evaluation of art and craft materials consists of a review of the following to determine the potential health hazards:
c) The Department shall consider the findings and conclusions of a voluntary art and craft material certifying organization as to the appropriateness of placement of any product on the Department's art and craft materials exclusion list if:
2) Such voluntary certifying organization discloses to the Department the standards and procedures used by its certifying toxicologist for determining whether art and craft materials contain toxic substances causing chronic illness and if so, whether such substances can reasonably be expected to pose or not to pose a risk of adverse health effects. The Department may determine to add any product to such art and craft materials exclusion list for good cause. (Good cause shall mean what the department, through its evaluation or based upon the findings and conclusion of an approved organization, finds that an art or craft material is hazardous). Such determination shall afford due consideration to uniform determinations by other state health departments or agencies and voluntary certifying organizations as specified above on this subject.
