Compliance shall be measured by a flame ionization detector or other device approved by the department. Any approval of an alternative device issued by the department under this subsection shall be submitted to, and will not become effective for federal purposes until approved by, the administrator or designee as a source-specific revision to the department's state implementation plan for ozone.
