Asbestos Abatement
AHERA · EPA NESHAP · OSHA Compliant
Pre-1981 Phoenix-area buildings frequently contain asbestos-containing materials. DRR handles inspection, abatement, monitoring, and regulated disposal with AHERA-licensed inspectors and in-house crews — one contract, one accountable firm.
What We Do
End-to-End Asbestos Workflow
Pre-Demolition & Renovation Surveys
AHERA · EPA NESHAP
Before any work that could disturb building materials, a licensed asbestos inspector is required in most Arizona jurisdictions. Our AHERA-licensed inspectors test suspect materials, sample them per EPA protocol, and issue a defensible survey report.
- AHERA-licensed building inspectors
- PLM / TEM sampling via NVLAP-accredited labs
- Full survey report with homogeneous area maps
- Quick turn-around on urgent pre-demo projects
Containment & Abatement
OSHA 1926.1101 / EPA NESHAP
Abatement crews remove regulated asbestos-containing materials under strict engineering controls: negative-pressure containment, HEPA filtration, and glove-bag removal for small-scope jobs. Every project is documented for regulator, carrier, and owner review.
- Negative-pressure containment zones
- Glove-bag and critical-barrier methods
- Wet-removal techniques per OSHA
- Licensed supervisor on every crew
Air Monitoring
NIOSH 7400 / AHERA
Pre-disturbance, during abatement, and post-abatement air monitoring protects workers, occupants, and project schedules. Our third-party industrial hygiene partners deliver real-time fiber counts and final clearance samples.
- Pre-abatement baseline sampling
- Continuous perimeter monitoring
- Aggressive final clearance sampling
- NIOSH 7400 PCM + TEM confirmation
Regulated Waste Disposal
EPA / ADEQ
Asbestos waste is a federally regulated material. Every pound leaves the site double-bagged, labeled per 40 CFR 61 Subpart M, manifested, and tracked to an ADEQ-approved landfill — with hauler certificates delivered to the owner at closeout.
- Double-bagged waste with OSHA labels
- Chain-of-custody manifests
- Disposal at approved ADEQ landfills
- Owner closeout documentation package
Clearance & Closeout
AHERA · NESHAP
A full closeout package includes pre-/post-air monitoring data, waste manifests, supervisor logs, photo documentation, and a final clearance letter — everything an owner, lender, or carrier needs on file.
- Final clearance air-sample letter
- Complete photo log with timestamps
- Waste manifests and hauler certificates
- Owner-ready PDF package delivered within 7 days
Credentials
Licensed & Certified
Every asbestos project is performed by DRR employees — not subcontractors — with the licenses, training, and insurance required by state and federal law.
