For the purposes of determining operational readiness following completion of physical construction of a hazardous waste incinerator, the commission shall establish permit conditions including, but not limited to, specification of allowable waste feeds and operating conditions, in a permit for a new hazardous waste incinerator. These permit conditions will be effective for a minimum required time, not to exceed 720 hours operating time for treatment of hazardous waste, to bring the incinerator to a point of operational readiness sufficient to conduct a trial burn. The commission may extend the duration of this operational period once, for up to 720 additional hours, at the request of the applicant when good cause is shown. The permit may be modified to reflect the extension pursuant to § 305.69 of this title (relating to Solid Waste Permit Modification at the Request of the Permittee).
