The bill amends Chapter 23-24.5 of the General Laws, titled "Asbestos Abatement," to clarify and update regulations regarding the management and abatement of asbestos in buildings. It introduces new definitions for terms such as "asbestos exposure standards" and "asbestos abatement plans," which clarify the responsibilities of building owners and contractors. A key requirement is that owners of structures with friable asbestos must submit an abatement plan within twelve (12) months of receiving notice to avoid liability. The bill grants the director the authority to establish regulations for air exposure standards, inspection criteria, and the licensure of asbestos contractors, while imposing stricter requirements for the posting and labeling of buildings containing friable asbestos.

Additionally, the bill mandates that no asbestos abatement project can begin without a licensed contractor and an approved abatement plan, reinforcing compliance with safety standards. It includes provisions for fines and penalties for non-compliance. The bill also updates regulations related to radon control, requiring all individuals providing radon-related services to be certified or licensed, and mandates notification to the department before any radon mitigation activities in public and high-priority buildings. Overall, the act aims to enhance public health and safety by ensuring that asbestos and radon management is conducted by qualified professionals.
