The board of health of a health district in which a solid waste facility or an infectious waste treatment facility is located, or the director of environmental protection, may suspend, revoke, or deny a license for the facility for violation of any section of this chapter or any rule adopted under it. The director may suspend, revoke, or deny a permit to operate any hazardous waste facility for violation of any section of this chapter or any rule adopted under it. No application for a permit or license to be issued under this chapter shall be denied and no permit or license issued under this chapter shall be modified, suspended, or revoked without a written order stating the findings upon which the denial, suspension, modification, or revocation is based. A copy of the order shall be sent to the applicant or permit or license holder by certified mail. Unless an emergency exists requiring immediate action to protect the public health or safety or the environment, no suspension, modification, or revocation of a permit or license shall be made effective until the permit or license holder has been given notice in writing and, in the case of a permit holder, a reasonable period of time to make corrections. Appeal from any modification, suspension, revocation, or denial of a license shall be made in accordance with sections 3745.02 to 3745.06 of the Revised Code.
