Compost Facilities
Compost facilities must register with the Ohio EPA by calling (614) 644-2621. There is no license or permit fee required for Class III and IV composting facilities. 
For Class I and II facilities, a solid waste license is required in addition to the registration. Contact Ohio EPA for more information.
Hamilton County Public Health Environmental Health Specialists also inspect these facilities to ensure proper waste acceptance, water management and material tracking.
