California Code, Public Resources Code - PRC § 41780.1

(a) Notwithstanding any other requirement of this part, for the purposes of determining the amount of solid waste that a regional agency is required to divert from disposal or transformation through source reduction, recycling, and composting to meet the diversion requirements of Section 41780, the regional agency shall use the solid waste disposal projections in the source reduction and recycling elements of the regional agency's member agencies.  The method prescribed in Section 41780.2 shall be used to determine the maximum amount of disposal allowable to meet the diversion requirements of Section 41780.

(b) Notwithstanding any other requirement of this part, for the purposes of determining the amount of solid waste that a city or county is required to divert from disposal or transformation through source reduction, recycling, and composting to meet the diversion requirements of Section 41780, the city or county shall use the solid waste disposal projections in the source reduction and recycling elements of the city or county.  The method prescribed in Section 41780.2 shall be used to determine the maximum amount of disposal allowable to meet the diversion requirements of Section 41780.

(c) To determine achievement of the diversion requirements of Section 41780 in 1995 and in the year 2000, projections of disposal amounts from the source reduction and recycling elements shall be adjusted to reflect annual increases or decreases in population and other factors affecting the waste stream, as determined by the board.  By January 1, 1994, the board shall study the factors which affect the generation and disposal of solid waste and shall develop a standard methodology and guidelines to be used by cities, counties, and regional agencies in adjusting disposal projections as required by this section.

(d) The amount of additional diversion required to be achieved by a regional agency to meet the diversion requirements of Section 41780 shall be equal to the sum of the diversion requirements of its member agencies.  To determine the maximum amount of disposal allowable for the regional agency to meet the diversion requirements of Section 41780, the maximum amount of disposal allowable for each member agency shall be added together to yield the agency disposable maximum.
