LINCOLN, Neb. (AP) — Nebraska will loosen its sales tax limit on cities, allow counties to fight black-tailed prairie dogs, and restore prenatal care coverage to illegal immigrants with a series of new measures that are about to become law.

More than 160 new laws approved during this year’s legislative session are set to take effect Thursday, including Gov. Dave Heineman’s tax cut plan and measures designed to help local governments.

New laws generally take effect three months after the Legislature adjourns for the year, unless lawmakers specify a different date. State senators approved 246 new pieces of legislation during this year’s 60-day session. In 2011, they approved 269 bills.
