WALNUT CREEK -- Trash-handling consultants are recommending Arizona-based Republic Services and Pacific Rim Recycling of Benicia for up to $1 billion in franchise contracts to haul and recycle garbage in five Contra Costa County cities.

The recommendation comes after analysts commissioned by the Central Contra Costa Solid Waste Authority studied nine service proposals for pieces of the deal submitted last fall. Combined, the 10-year franchise agreements are worth $500 million, with a likely 10-year extension.

The authority oversees trash collection and recycling for 65,000 households in Danville, Lafayette, Moraga, Orinda, Walnut Creek and unincorporated areas.

Under the staff recommendation, Republic Services would collect and dispose of trash, run the transfer centers and process green and food waste. Pacific Rim would handle the recyclables.

The 12-member authority board -- consisting of two elected county supervisors and two council members from each of the five member cities -- is scheduled to consider the recommendation during a public hearing Thursday.

The board will likely also hear direct counter arguments from the unsuccessful bidders, including Mt. Diablo Recology, a new partnership between Garaventa Enterprises of Concord and San Francisco-based Recology.

Pacific Rim and Republic, also the current operator, offer residents the "best value" with 4.4 percent lower annual costs than Mt. Diablo Recology, the consultants concluded. Monthly service rates are based on expenses.
