‘Sec. 1. 25 MRSA §2466 is enacted to read:
§ 2466. Radon standard
1. Maine model radon standard for new residential construction. "Maine model radon standard for new residential construction" means the standard published by the American Society for Testing and Materials designated as E-1465-06 Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings.
2. Standard or code adoption by municipalities. A municipality may not adopt a radon standard or code for new residential construction other than the Maine model radon standard for new residential construction. Nothing in this section requires a municipality to adopt a radon standard or code for new residential construction.
3. Municipal standards or codes adopted. A radon standard or code for new residential construction adopted by a municipality prior to the effective date of this section is not invalidated by this section, except that if the municipality replaces that standard or code it must adopt the Maine model radon standard for new residential construction.
4. References within standard. Codes and standards other than E-1465-06 Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings that are referenced within the Maine model radon standard for new residential construction are not automatically adopted as part of the Maine model radon standard for new residential construction.’
