A plan that alters regulations for the operation of a wastewater treatment plant that disposes of effluent into a Sierra Nevada foothills creek, rather than requiring improvements to the plant, has been upheld by the First District Court of Appeal.

Anglers and environmentalists sued over the plan, arguing state water quality regulators violated the California Environmental Quality Act and the Porter-Cologne Water Quality Control Act. But a unanimous three-judge panel of the First District, Division One, ruled for the government.

Redevelopment may have been the biggest winner in Tuesday's primary election. Statewide, voters rejected Proposition 98, an initiative to prohibit the use of eminent domain for economic development purposes. In San Francisco, voters supported a huge redevelopment project at the former Hunter's Point shipyard and Candlestick Point. And in Napa County, voters rejected a slow-growth initiative that was aimed at halting redevelopment of a former industrial site just south of Napa.
