OKLAHOMA CITY (AP) — Oklahoma lawmakers may have adjourned the 2011 session, but members will return to the state Capitol during the legislative interim to examine several thorny issues.

Among the proposals scheduled for study later this year are long-range policies for the state's water resources and a look at the hundreds of millions of dollars in tax breaks handed out by the state each year.

Lawmakers also plan to study further changes to the state's pension systems and the state's liquor laws, including the sale of wine and "strong beer" at grocery stores.

Legislative leaders say they expect about 50 interim studies to be approved in the House, and another 30 in the Senate.

A Senate spokesman said Monday he expects the list of Senate studies to be approved later this week.
