DENVER — Gov. Bill Ritter signed 16 bills on Thursday, including one barring Colorado residents from obtaining concealed weapons permits from other states.

Out-of-state visitors will be allowed to use permits issued by their home states, and not a third state, under the law (Senate Bill 34).

House Majority Leader Alice Madden, D-Boulder, said she sponsored the bill because she was concerned people denied permits in Colorado could get them elsewhere.

Dudley Brown, spokesman for Rocky Mountain Gun Owners, said the bill could prevent some people who travel from defending themselves and their families when they are in Colorado.

Colorado permit holders must apply in person and undergo a background check. The permit costs $152.50 and lasts for five years.

Other new laws include one that will streamline procedures for notifying owners of mineral interests about planned surface development and will regulate negotiations of surface use agreements. Another requires treatment for firefighters with cancers that could be related to their jobs.

Ritter still has about 200 bills to sign before a June 4 deadline.
