The manufacturer shall submit with the petition a plan that shall include:
The exemptions provided in paragraphs (8) and (9) shall expire on January 1, 1997, except that any exemption provided in paragraph (8) or (9) may be renewed by the department after this date for periods not to exceed two years. Any renewal granted by the department for the exemption provided in paragraph (8) or (9) shall be based on evidence furnished to the department that there is no feasible method to reduce the concentration levels of lead for the specified package or packaging component.
For the purposes of this subsection, a use for which there is "no feasible or practical alternative or substitute" means one in which the use of lead, cadmium, mercury or hexavalent chromium is essential to the protection, safe handling, or function of the contents of the package.
