1 KPBS News has learned the California Air Board has been under-estimating greenhouse gases from San Diego County landfills. Landfills create methane gas – 21 times more potent as a greenhouse gas than carbon dioxide.California Air Board Greenhouse Gas Emissions from S.D. Landfills Underestimated Apr 03, 2008 Based on gas capture rates KPBS obtained from county landfill operators, the real emissions were much higher than the estimates.

7 MWD's net power use for 2006 MWD diverted 632 kaf of CRA water [200B gallons], and it used 1,230 GWh to divert this amount of water at a total cost of $6.8M. MWD took 1.51 maf of SWP water [500B gallons], used 4,500 GWh to transport this amount at a total cost of $198M. MWD used 80 GWh to distribute and treat the water at a total cost of $8.7M.

11 The Point Loma outfall currently discharges effluent (treated sewage) five miles offshore of San Diego; however, it has been treated only to advanced primary levels. The CWA requires all cities in the United States to treat their sewage to secondary levels before discharging it into rivers, lakes, etc. But for the last few years, San Diego has argued that these standards are unreasonable for coastal cities with deep ocean outfalls far offshore.

SAN DIEGO – The city of San Diego is the state's last holdout from a federal law (CWA) requiring secondary treatment for sewage discharged into the ocean. San Diego gained that status after two Central Coast agencies recently committed to complying with the mandate. About 40 sewage treatment plants statewide pump their effluent into the Pacific Ocean.

SAN DIEGO, California, The city of San Diego will spend over $1 billion to improve its aging sewer system and prevent future spills of raw, untreated sewage into local streams, the ocean, and city streets," said the EPA assistant administrator for enforcement and compliance assurance. "When this suit was initiated, the city was averaging a sewage spill a day and gaining national notoriety for massive spills like the 34 million gallon spill into Adobe Creek and the San Diego River," said Coastkeeper Executive Director Bruce Reznik.

12 Serious Issues to Ponder How do decisions we make in California affect the environment in other parts of the world? How do decisions we make in California affect the environment in other parts of the world? The impact of our public policy, business and individual decisions is profound. The impact of our public policy, business and individual decisions is profound. The decision, for example, not to drill for oil off California's coastline has wide public support, for good reason. It allows California to preserve its wondrously scenic coastal beauty. The decision, for example, not to drill for oil off California's coastline has wide public support, for good reason.

Your own ecological footprint can be calculated in acres on the Web site The result of my wife and me living in a 2,000-square-foot home, driving only one car, one of us usually using public transportation (or bike) except to travel occasionally by air, and seldom eating meat is that we would still need 3.4 planets if everyone in the world lived this way.
