(b)  This section does not apply to units which become eligible for authorization under a permit-by-rule, conditional authorization, or conditional exemption due to a change in the waste streams or treatment activities described for the unit in the hazardous waste facilities permit or grant of interim status document for the unit.

(B)  A written request, signed in accordance with the regulations adopted by the department pertaining to signatories to permit applications and reports, to administratively terminate the existing hazardous waste facilities permit or grant of interim status if the unit subject to the permit or grant of interim status is the only unit at the facility authorized by that permit or grant of interim status.

(d)  Upon receipt of a notification, if applicable, and a request pursuant to paragraphs (3) and (4) of subdivision (c), the department shall do all of the following:

(1)  Either approve the request in writing if the department concurs with the demonstrations submitted pursuant to paragraphs (1) and (2) of subdivision (c) and the notification submitted pursuant to paragraph (3) of subdivision (c) is complete and valid; or deny the request in writing if the department does not concur with the demonstrations submitted pursuant to paragraphs (1) and (2) of subdivision (c) or the notification submitted pursuant to paragraph (3) of subdivision (c) is incomplete or invalid.

(2)  If not all activities conducted at a facility pursuant to a hazardous waste facilities permit or grant of interim status are eligible for conversion, administratively terminate the authorization under the hazardous waste facilities permit or grant of interim status for the unit or units at the facility conducting treatment activities eligible to be authorized under a permit-by-rule pursuant to the department’s regulations, or a grant of conditional authorization or conditional exemption pursuant to this chapter, by doing all of the following:

(A)  Placing a letter in the facility permit file maintained by the department acknowledging the change in authorization.

(B)  Notifying the facility, in writing, that the authorization under the permit or grant of interim status for the treatment units in question will be terminated when the authorization under a permit-by-rule pursuant to the department’s regulations, or a grant of conditional authorization or conditional exemption pursuant to this chapter, becomes effective.

(C)  Notifying all persons on the facility mailing list of the change in the authorization status of the units being converted.
