HOUSTON — Days before a newly formed council focuses on a long-term Gulf of Mexico cleanup, a report shows that one federal agency has committed more than a half-billion dollars to the region in the past two years, nearly one-fifth of it on projects linked to recovery from the 2010 oil spill.

The US Department of Agriculture’s Natural Resources Conservation Service, one of the so-called ‘‘trustees’’ involved in divvying up projects and cash from a settlement with BP PLC, detailed in a report it will present next week at the meeting in Mobile, Ala., its Gulf Coast projects, the money it has invested, and the acres affected. The report was released to the Associated Press in advance.
