"The Trump administration has illegally delayed rules limiting the discharge of climate-changing methane gas from landfills around the United States and must act on plans for California and several other states by September, a federal judge ruled Monday.

The EPA was to approve or disapprove the state plans by Sept. 30, 2017, and to prepare its own solution two months later for states without an approved plan.

President Trump’s EPA has received plans so far from California, New Mexico, Arizona, Delaware and West Virginia, but has not acted on them or proposed its own plan, Gilliam said. He said the agency has not justified its inaction but has argued only that the states have no legal authority to sue and have not presented a practical timetable for compliance."
