While Pacific Gas & Electric\u2019s plan for high-energy 3-D sonic data gathering on earthquakes near its Diablo Canyon nuclear plant was dashed this month by the California Coastal Commission, a low-energy version of the same tests on the state\u2019s other operating nuclear facility is expected to begin next year, according to Southern California Edison. \u201cOur proposed plan, but not finalized, has always been based on 2-D [low-energy] collection first,\u201d noted spokesperson Jennifer Manfrè. \u201cThey have a lot to think about,\u201d said Coastal Commission deputy director, Alison Dettmer. She added Edison\u2019s staff is expected to meet with the commission on the issue \u201cafter the New Year.\u201d Also, the commission is set to hear the SONGS annual status report at its Dec. 14 meeting. The facility is permitted to take in 2.3 billion gallons\/day of seawater, affecting marine life. As it\u2019s built on the coast, it also affects the surrounding terrestrial environment. Since 1991, the commission\u2019s required mitigation. This year\u2019s report notes the progress of a $1 million fish hatchery, dredging to improve wetlands restoration, and an artificial kelp reef operation. The plant\u2019s owners pay for commission staff involvement in oversight.
