DE Asbestos Abatement

The DNREC Division of Air Quality's Asbestos Management Program, working with the Division of Waste and Hazardous Substances and the Office of Management and Budget's Division of Facilities Management. The program regulates removal, transport, and disposal of asbestos statewide. Contact points differ by topic: demolition and renovation questions go to the asbestos program in Dover, disposal and hauler questions to the solid and hazardous waste section, and inspection firm or contractor questions to the abatement services office.

Owners or operators must notify DNREC, as required, at least ten working days before any activity that may disturb asbestos-containing materials. Count working days, not calendar days, and build the notice into your project schedule before mobilization. The source page phrases this as a minimum, so treating ten working days as a floor rather than a target is the safer exam answer.

Yes, with limits. Homeowners in single-family, owner-occupied homes may do the work themselves provided they package and dispose of the waste properly. DNREC still urges extreme caution and suggests considering a licensed abatement contractor for most removal projects. Owner-occupancy and single-family status are the conditions to watch in scenario questions; a rental or multi-unit building does not fit this allowance.

Contact the Delaware Solid Waste Authority and arrange to bring the material to one of its transfer stations or landfills. DSWA requires homeowners to call 24 hours in advance and make an appointment before bringing any asbestos-containing waste to its facilities. Other requirements may include completing a DSWA Asbestos Disposal Form. The DSWA Citizen's Response Line is 1-800-404-7080.

Asbestos-containing materials may only be transported by approved hazardous waste haulers and disposed of in approved disposal facilities. DNREC's Division of Waste and Hazardous Substances maintains the list of waste haulers permitted to transport asbestos; call 302-739-9403 for a copy. Exam scenarios often hinge on whether a general hauler or an approved hauler is used, so learn the distinction cold.

Owners are advised, and may be required, to have an inspection by a Delaware-licensed asbestos inspector before removing asbestos-containing materials during renovation or demolition. Then notify DNREC at least ten working days before disturbance, use approved haulers, and dispose at approved facilities. Material in good condition that will not be disturbed should be left alone; deteriorating material or material that will be disturbed must be removed.

Not entirely. Facility owners and fire companies conducting demolitions for fire training must meet the notification and approval requirements outlined in the Delaware Open Burning Program, in addition to the asbestos requirements that apply. This is a common trap: candidates assume any demolition follows one path, when fire-training burns add a separate approval track through the open burning program.

DNREC lists heating system insulation, spray-applied insulation, vinyl floor tiles, vinyl sheet flooring, ceiling tiles, adhesives and construction mastics, roofing paper and shingles, cement siding shingles, plaster and joint compound, and vermiculite. Peak usage ran from 1950 to 1975, though materials were used through the 1980s. Watch for tremolite contamination in vermiculite attic insulation.

Start with health effects and material identification together, because they explain why the work practice rules exist. Then take notification and demolition/renovation requirements, since the ten-working-day notice and inspection triggers drive most scenarios. Finish with work practices, licensing, and waste transport and disposal as one block. All five domains are weighted equally, so do not let disposal timelines crowd out health effects review.
