Recology Hay Road Recology Hay Road (RHR) provides solid waste disposal services to both municipal and commercial customers in the San Francisco Bay Area and the Sacramento Valley. The site primarily serves San Francisco as well as Solano County, specifically the cities of Vacaville and Dixon. In 1964, RHR began operation and built its first liner system in 1992. The site is comprised of 640 acres, 256 of which are permitted as a Class II landfill.

Please become familiar with the RHR untarping procedures that have been implemented as well as the definitions of waste types that are accepted.

Untarping Requirements
When entering RHR, customers are required to untarp all covered loads to expose the material contained in the vehicle. Designated video recorded untarping areas are available to efficiently accomplish this task before approaching the weigh station. If tarps are not removed as required, customers will be asked to exit the lane and drive to the posted untarping areas. Once loads are untarped, customers may courteously merge into a weigh station lane.

Acceptable Permitted Waste Materials
Municipal Solid Waste (MSW) – Garbage and non-hazardous refuse. This includes mixed waste materials which are NOT recyclable that are generated by residential, commercial, and institutional customers to be disposed of in the landfill.

Special Wastes – Contaminated soils, dredge debris, and specific commercial wastes are solid special waste materials that are below hazardous levels and can be reused or disposed of in a Class II landfill. These materials are subject to analytical review, and must be classified non-hazardous under the state’s hazardous waste criteria.

Special Wastes
  • Ash – Residual material from a fire which contains non-hazardous levels of metals and minerals.
  • Contaminated Soil – Soil (with less than 5% debris) that has contamination with constituents below state and federal hazardous limits. RHR requires any soil suspected of contamination to be tested based on generator knowledge and site history.
  • Hazardous Asbestos* – Asbestos containing materials are hazardous if they contain 1% or more friable asbestos. Friable asbestos containing material can be easily crumbled or reduced to powder, becoming an airborne hazard.
  • Non-Hazardous Asbestos* – Asbestos containing materials are non-hazardous if they contain less than 1% friable asbestos. These materials are also non-hazardous if they are non-friable, meaning they cannot be easily crumbled or reduced to powder.
  • Treated Wood Waste – Wood that has been treated with a chemical preservative (i.e., creosote, copper, arsenic) including railroad ties, grape stakes and other manufactured lumbers (i.e., fence posts, deck pillars).

Other Acceptable Materials
  • Concrete (Clean) – Clean concrete that is dry and does not contain other demolition materials (i.e., rebar, wood, inerts). Clean concrete is recycled onsite.
  • Construction and Demolition Debris (C&D) - Includes, but is not limited to concrete, wood, and drywall, usually found as a mixed material.
  • Metal, Appliances and White Goods – Metal and appliances (i.e., washers, dryers, refrigerators, stoves) containing metal is recycled. White goods containing Freon, oils, electrical circuits, compressor oils, and mercury switches are accepted for an additional appliance surcharge.
  • Soil (Clean) – Clean soil and dirt are accepted when the required Clean Soil Certification form is completed by the generator. This signed form must be submitted verifying that the soil is clean and free from contaminants.
  • Tires – Whole car and truck tires, with rims removed, are recycled for an additional fee.
  • Used Motor Oil – Non-commercial used vehicle motor oil is collected at the Used Oil Collection Center onsite.
  • Yard Trimmings and Food Scraps – Organic materials are accepted and converted into earth-friendly, nutrient-rich soil amendments at Jepson Prairie Organics.
  • Wood – Unpainted lumber, pallets and scrap wood are all recycled onsite. If the wood is mixed with non-wood materials, it is considered MSW and will be directed to the landfill.
