Indiana Asbestos Regulations & Compliance Guide (2026)

Last updated: August 13, 2026

Executive Summary

Asbestos work in Indiana is regulated by three separate agencies at once: OSHA governs worker safety and exposure limits, EPA sets accreditation standards and demolition/renovation work practices, and the Indiana Department of Environmental Management (IDEM) administers state licensing, notification, and enforcement. Missing any one of the three can mean a compliant-looking project is still in violation.
The practical stakes are real. OSHA serious violations run up to $16,550 per citation (willful or repeat violations up to $165,514). EPA's Asbestos NESHAP carries a statutory base penalty of $25,000 per day per violation under the Clean Air Act, adjusted upward for inflation. IDEM can independently assess civil penalties up to $25,000 per day per violation under Indiana law — and federal and state penalties can apply to the same project simultaneously.
This guide covers what OSHA, EPA, and IDEM each actually require, Indiana's licensing and notification rules, what non-compliance actually costs based on real enforcement cases, and a practical compliance checklist for employers and contractors.

Who Regulates Asbestos in Indiana?

Three agencies share jurisdiction, and they don't overlap as much as people assume — each one governs a different piece of the same project.
OSHA protects workers on the job site itself: exposure limits, respiratory protection, PPE, medical surveillance, and employer safety duties. OSHA does not issue asbestos certifications and does not regulate what happens to the material once it leaves the building.
EPA sets the accreditation framework that makes training programs legitimate in the first place, and separately regulates what happens during demolition and renovation — notification, work practices, and waste disposal — regardless of who's doing the work.
IDEM administers Indiana's own licensing program, requires advance notification before regulated demolition or renovation projects, and enforces compliance within the state — including its own civil penalty authority that's independent of OSHA and EPA.
A single asbestos abatement project is routinely subject to all three at once. Understanding which agency governs which piece is the difference between a compliant project and an expensive mistake

OSHA Asbestos Regulations in Indiana

OSHA's asbestos requirements come from two standards depending on the setting: the construction standard (29 CFR 1926.1101) for abatement, renovation, and demolition work, and the general industry standard (29 CFR 1910.1001) for maintenance and custodial work in existing buildings.
Both standards set a permissible exposure limit (PEL) of 0.1 fiber per cubic centimeter of air as an 8-hour time-weighted average, with a 1.0 fiber/cc excursion limit over any 30-minute period. Exceeding these limits is a violation regardless of whether any visible contamination occurred.
OSHA's construction standard also divides asbestos work into four classes based on risk:
Class I — the highest-risk work: removing thermal system insulation (TSI) and surfacing ACM or presumed ACM.
Class II — removing other types of ACM, such as floor tile, roofing, or siding.
Class III — repair and maintenance work that may disturb ACM.
Class IV — custodial and cleanup work involving ACM debris, but not disturbing it directly.
Training requirements, engineering controls, and required PPE scale directly with the class of work — Class I work carries the most stringent requirements, including a "competent person" on-site at all times. Training for hands-on Class I and II work is covered in our Asbestos Worker Initial course.
For buildings constructed before 1980, OSHA requires employers to presume that thermal system insulation, sprayed-on surfacing materials, and asphalt or vinyl flooring contain asbestos unless testing (polarized light microscopy) proves otherwise. Disturbing presumed ACM without proper classification, training, and controls is treated as a serious — potentially willful — violation.
OSHA also requires medical surveillance for employees exposed above the PEL on 30 or more days per year, and detailed recordkeeping of exposure monitoring, training, and medical records.

EPA Asbestos Regulations: AHERA and the Asbestos NESHAP

EPA regulates asbestos through two distinct frameworks that serve different purposes
AHERA (Asbestos Hazard Emergency Response Act), codified at 40 CFR Part 763, establishes the accreditation requirements for asbestos training programs. This is what makes a course "EPAaccredited" in the first place — it sets the curriculum and testing standards that training providers like SafeCru must meet.
The Asbestos NESHAP (National Emission Standard for Hazardous Air Pollutants), at 40 CFR Part 61, Subpart M, governs what happens during demolition and renovation, independent of who's performing the work or what certification they hold. Key NESHAP requirements include:
  • Advance written notification to the appropriate regulatory authority (IDEM, in Indiana) before starting most demolition projects and renovations involving a threshold amount of regulated ACM.
  • The "adequately wet" requirement — ACM must be kept wet during stripping, removal, and handling to prevent fiber release, except in specific circumstances where wetting isn't feasible.
  • Work practice standards for containment, handling, and transport of ACM.
  • Proper waste disposal at an authorized disposal site, with documentation.
NESHAP applies based on the quantity of regulated ACM involved — generally, projects disturbing at least 260 linear feet on pipes, 160 square feet on other components, or 35 cubic feet where length or area can't be measured. Below those thresholds, some NESHAP requirements don't apply, but Indiana's own rules may still require notification — always confirm both federal and state thresholds before assuming a project is exempt.
Residential structures aren't automatically exempt either — a single-family home demolition connected to a larger commercial or public project (like a redevelopment or highway project) is still subject to NESHAP.

IDEM Regulations & Indiana-Specific Requirements

IDEM administers Indiana's asbestos program under Title 326 of the Indiana Administrative Code, primarily 326 IAC 18 (asbestos management personnel — licensing and accreditation) and 326 IAC 14-10 (emission standards for demolition and renovation, Indiana's version of the NESHAP work practice rules).
In practice, IDEM requires:

Advance written notification

typically at least 10 working days before starting a regulated demolition or renovation project — submitted on IDEM's Notification of Demolition and Renovation Operations form. In some Indiana cities (Indianapolis, for example), notification also goes to the local environmental services agency in addition to IDEM.

Licensed personnel

anyone performing regulated abatement work must hold current Indiana accreditation in the applicable discipline (worker, supervisor, inspector, etc.), and companies must hold an Indiana asbestos contractor's license

Inspection before renovation or demolition

a thorough asbestos inspection by an Indianalicensed inspector is required before renovation or demolition activity begins, to identify regulated ACM that must be removed first.

Removal before disturbance

regulated ACM generally must be removed by licensed personnel before any activity that could disturb it, not discovered and dealt with mid-project.

Wetting, containment, and cleanup

consistent with EPA NESHAP, plus Indiana-specific documentation requirements, including a final visual inspection by a licensed supervisor before a work area is released.
IDEM enforces these rules independently of OSHA and EPA, through its own Office of Enforcement, and collects civil penalties into Indiana's dedicated Asbestos Trust Fund.

Licensing & Accreditation Requirements in Indiana

Indiana requires individual accreditation for anyone performing regulated asbestos work, issued by IDEM after completing an approved training course and passing the state exam for that discipline (worker, supervisor, inspector, management planner, etc.).
Companies performing abatement also need a separate Indiana asbestos contractor's license, which requires a designated supervisor-level representative and proof of asbestos liability insurance (commonly at least $500,000) with IDEM listed as certificate holder.
Indiana does not offer blanket license reciprocity with other states — workers certified elsewhere still need to meet Indiana's own licensing requirements, including the state exam. For a full breakdown of the certification levels, costs, and step-by-step licensing path, see our Indiana Asbestos Certification Guide.

What Happens If You Don't Comply? Penalties for Asbestos Violations

Non-compliance carries real financial exposure at all three levels — and the three don't cancel each other out. A single project with violations can face OSHA, EPA, and IDEM penalties concurrently.

Asbestos Violation Penalty Exposure

Maximum civil penalties by regulatory agency (2026 figures).

OSHA

  • Serious: up to $16,550
  • Willful/repeat: up to $165,514
  • Per violation, per citation

EPA (NESHAP)

  • Statutory base: $25,000/day
  • Inflation-adjusted: much higher
  • Per violation, per day

IDEM (Indiana)

  • Up to $25,000/day/violation
  • Real cases: 5,000–110,000+
  • Paid to Asbestos Trust Fund
  • Federal and state penalties can apply simultaneously — a single project can trigger OSHA, EPA, and IDEM exposure at once.
SafeCru Safety Resource Center
Asbestos Violation Penalty Exposure
OSHA penalties for 2026 (adjusted annually for inflation) run up to $16,550 per serious violation, and up to $165,514 per willful or repeat violation. Failure to correct a cited hazard can add daily penalties on top of the original citation
EPA penalties under the Clean Air Act's NESHAP provisions carry a statutory base of $25,000 per day per violation, which is adjusted upward for inflation under federal penalty adjustment rules — actual assessed penalties in real enforcement cases have run well into six figures. EPA can pursue both the building owner and the abatement contractor independently, since the regulation defines "owner or operator" broadly. Knowing violations can also result in criminal prosecution.
IDEM is authorized under Indiana Code 13-30-3-4 to assess civil penalties up to $25,000 per day per violation. Real Indiana enforcement cases illustrate the range: penalties have included $5,000 for a single wetting violation, $21,000 for an interrupted-project storage violation, and $110,000 in a case involving failure to inspect, failure to notify, failure to remove ACM before renovation, and hiring an unlicensed contractor. IDEM typically offers a 60-day settlement window through an Agreed Order before pursuing a unilateral Commissioner's Order, and penalties may be reduced for documented mitigating circumstances or through a Supplemental Environmental Project (SEP).
The common thread across real cases: the most expensive violations aren't exotic technical failures — they're the basics. Failure to notify, failure to inspect first, failure to wet material, and using unlicensed labor account for the large majority of enforcement actions at every level.

Compliance Checklist for Employers and Contractors

Before starting any project involving known or presumed ACM:
  • Confirm a licensed inspection has been completed and documented
  • Verify notification has been submitted to IDEM (and local authorities, where required) at least 10 working days before start
  • Confirm every worker on-site holds current, non-expired Indiana accreditation for their role
  • Confirm the contractor holds a current Indiana asbestos contractor's license and required insurance
  • Verify a written removal and disposal plan is in place, including an approved disposal site
  • Confirm engineering controls, containment, and PPE match the OSHA work class involved
  • Maintain exposure monitoring, training, and medical surveillance records
  • Schedule a final visual inspection by a licensed supervisor before releasing the work area

Not Sure Which Certification Applies to Your Situation?

Every requirement in this guide traces back to one question: what certification does your role actually need? Our Indiana Asbestos Certification Guide walks through the decision step by step — Awareness, O&M, Worker, or Supervisor — based on the work you're actually performing.
