Cal. Public Resources Code - PRC 10.5.

in effect

Cal. Public Resources Code - PRC § 25910. Section 25910.

The commission shall, by regulation adopted no later than July 1, 1978, establish minimum standards for the amount of additional insulation (expressed in terms of R-value) installed in existing buildings. One year after the adoption of those standards, no insulation shall be installed in any existing building by a contractor unless the contractor certifies to the customer in writing that the amount of insulation (expressed in terms of R-value) meets or exceeds the minimum amount established by the standards. The minimum standards may vary for different types of buildings or building occupancies and different climate zones in the state. The minimum standards shall be economically feasible in that the resultant savings in energy procurement costs shall be greater than the cost of the insulation to the customer amortized over the useful life of the insulation.

Cal. Public Resources Code - PRC § 25911. Section 25911.

The State Energy Resources Conservation and Development Commission may adopt regulations pertaining to urea formaldehyde foam insulation materials as are reasonably necessary to protect the public health and safety. These regulations may include, but are not limited to, prohibition of the manufacture, sale, or installation of urea formaldehyde foam insulation, requirements for safety notices to consumers, certification of installers, and specification of installation practices. Regulations adopted pursuant to this section shall be promulgated after public hearings in accordance with Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code. Any regulation adopted by the commission to prohibit the sale and installation of urea formaldehyde foam insulation shall be based upon a record of scientific evidence which demonstrates the need for the prohibition in order to protect the public health and safety.

Cal. Public Resources Code - PRC § 25912. Section 25912.

Prior to adopting any regulation which causes a prohibition on the sale and installation of urea formaldehyde foam insulation, the commission shall consult with, and solicit written comments from, all of the following: (a) Federal and state agencies with appropriate scientific staffs, including, but not limited to, the State Department of Health Services, the National Academy of Sciences, the United States Department of Housing and Urban Development, the United States Department of Energy, and the United States Consumer Product Safety Commission. (b) Universities and public and private scientific organizations.
