We've mentioned before that the oil spill in the Gulf of Mexico is likely to have an impact on onshore E&P operations. Some environmental groups certainly hope so - here is a copy of a joint letter recently sent to Speaker Pelosi (D-CA) and Majority Leader Reid (D-NV) by Earthjustice, the Natural Resources Defense Council, and the Sierra Club (among others) urging Congress to further restrict oil and gas development in the nation. Their hook: "While national attention has been understandably focused on offshore production as the disaster in the Gulf of Mexico unfolds, the risks to our environment, our food, our water, our air, our health, our wildlife, and our natural resources, do not begin or end at our shorelines."
