No property is exempt from the Household Hazardous Sweeps (Phase 1) Hazardous Waste Sweep. Your property may qualify for an exemption from Phase 2 of debris removal if the only burn debris on a parcel is from non-residential structures less than 120 square feet, fences, and non-structural wood material. No work plan is required as long as the structures did not contain paint, pesticides, herbicides, propane or other similar hazardous substances, and requirements listed in the Conditional Exemption from Sonoma County Debris Removal Requirements are followed.  A conditional exemption approval from the Department of Health Services, Environmental Health is required before any work on your site can begin.  Additional exemptions may be granted on a case by case basis where the structure is greater than 120 square feet and all material contained within the structure is inert. You may not apply for an exemption if the County has flagged your property as potentially containing Household Hazardous Waste (HHW) or asbestos.
