DOSH-Certified Hazardous Waste Removal in Northern California
Licensed hazardous material removal, contaminated debris hauling, and disposal coordination with certified Class II facilities. CSLB HAZ and ASB classifications.
Handling hazardous materials on construction and demolition projects demands specialized licensing, training, and strict adherence to federal and state environmental regulations. Walberg, Inc. is DOSH certified and holds both HAZ (hazardous) and ASB (asbestos) classifications on our California contractor's license (CSLB #898860), qualifying us to handle hazardous waste removal on projects throughout Tehama, Butte, Shasta, Glenn, Colusa, and surrounding areas. Our crews are trained in the safe identification, handling, containment, and transport of hazardous materials commonly encountered in construction, demolition, and environmental remediation work.
Hazardous materials on construction sites take many forms. Older buildings may contain asbestos in floor tiles, ceiling textures, pipe insulation, roofing materials, and siding. Lead-based paint is common in structures built before 1978. Demolition of industrial and agricultural facilities may reveal chemical storage residues, petroleum-contaminated soils, and other regulated materials. Fire debris from structural fires is considered contaminated waste containing heavy metals and potentially asbestos fibers. In every case, these materials must be handled according to specific Cal/OSHA, EPA, and DTSC regulations to protect workers, the public, and the environment.
Our hazardous waste removal services include identifying suspect materials during pre-demolition surveys, coordinating sampling and laboratory analysis with certified industrial hygienists, implementing containment and worker protection measures during removal, properly loading and manifesting hazardous waste for transport, and coordinating disposal at licensed Class II facilities. We maintain all required documentation throughout the process, including chain-of-custody records, waste manifests, disposal certificates, and worker exposure monitoring records.
Walberg, Inc. has performed hazardous waste removal work on post-wildfire cleanup projects, commercial demolitions, industrial site remediations, and contaminated property cleanups. Our 26 years of experience in this specialized field means our crews understand both the regulatory requirements and the practical realities of safely handling dangerous materials in the field. We work closely with environmental consultants, industrial hygienists, and regulatory agencies to ensure that every project meets or exceeds compliance standards. Property owners and general contractors throughout Northern California trust our DOSH-certified team to handle their most sensitive hazardous material challenges.

OUR PROCESS
How we deliver hazardous waste removal.
Hazmat Assessment & Material Identification
We conduct a thorough site assessment to identify potential hazardous materials, coordinate sampling and laboratory analysis with certified industrial hygienists, and develop a materials management plan that addresses each identified hazard.
Regulatory Compliance & Safety Planning
We prepare all required regulatory notifications, develop site-specific health and safety plans, establish containment zones and decontamination procedures, and ensure all workers have current hazmat training certifications appropriate for the materials being handled.
Removal, Containment & Transport
Our DOSH-certified crews remove hazardous materials following strict containment protocols, properly package and label waste according to DOT requirements, prepare waste manifests, and coordinate transport to licensed Class II disposal facilities using certified haulers.
Clearance Verification & Documentation
After removal is complete, we coordinate clearance sampling to verify that the site meets applicable cleanup standards. We compile a complete documentation package including waste manifests, disposal certificates, clearance reports, and regulatory compliance records for the property owner's files.

FAQ
Frequently Asked Questions
DOSH stands for the Division of Occupational Safety and Health, which is the California agency that regulates worker safety in hazardous material handling. DOSH certification means our company and workers meet the training, safety, and competency requirements established by the state for handling hazardous materials on construction and demolition projects.
Hazardous waste removal costs depend heavily on the type and volume of materials involved, the level of containment required, and disposal fees at the receiving facility. Small-scale asbestos abatement might cost a few thousand dollars, while large-scale contaminated site cleanups can run into hundreds of thousands. We provide detailed estimates after completing a site assessment.
No. California law requires that an asbestos survey be conducted by a certified inspector before any demolition or renovation of structures that may contain asbestos-containing materials. Demolishing a building without proper testing and abatement can result in significant fines, project delays, and liability for contamination of surrounding areas.
A Class II disposal facility is a landfill licensed by the state to accept designated and non-hazardous waste that does not meet the criteria for a standard municipal landfill. This includes contaminated soils, asbestos-containing materials, and other regulated waste streams. Walberg, Inc. coordinates with licensed Class II facilities for proper disposal and obtains disposal certificates for your records.
Yes, post-fire debris removal is one of our core capabilities. Structural fire debris is typically classified as contaminated waste and may contain asbestos, heavy metals, and other hazardous constituents. Our DOSH-certified crews are experienced in handling fire debris in coordination with County Environmental Health requirements, and we have deployed to multiple major California wildfire events.
