What IDEM Regulates and Exemptions
What the exam tests
This domain tests the scope of IDEM's Asbestos Program under 326 IAC 14-10, which incorporates the federal NESHAP, and the situations that fall outside it.
Core rules and concepts
- IDEM regulates asbestos abatement projects, contractor and worker licensing, notification, work practices, waste handling, and approved training providers.
- The rule applies to facilities: institutional, commercial, public, industrial, and residential structures. A residential building with four or fewer dwelling units is generally excluded from the NESHAP notification and work-practice requirements, but OSHA worker-protection rules and waste-disposal requirements can still apply.
- Nonfriable ACM that is not rendered friable may be excluded from certain NESHAP work practices, but only if it is not cut, sanded, ground, or otherwise damaged.
- Category I and Category II nonfriable materials have narrow exclusions; demolition by burning, intentional crumbling, or catastrophic damage changes the analysis.
- Ordered demolitions and emergency renovations have special notification timing but are not exempt from emission controls.
- Public and private schools K-12 are separately covered by AHERA and must have a management plan.
Worked example
A homeowner removes 200 square feet of intact 9-inch floor tile from a single-family home. The building is a four-or-fewer dwelling unit residence, so Indiana's NESHAP notification is generally not required. The tile is Category I nonfriable; if it is pried up intact, certain work practices may not apply. If a contractor uses a grinder and creates dust, the material becomes RACM and the exclusion is lost; OSHA still protects the worker.
Traps
Do not treat the four-unit exclusion as a blanket residential exemption. Do not assume a small project is exempt from OSHA or landfill rules. Do not apply the nonfriable exclusion after the material has been damaged.
