OKLAHOMA CITY -- Members of the Oklahoma House will be busy this summer and fall as they convene hearings on 120 government studies that have been authorized by House Speaker Chris Benge.

Benge approved interim studies covering a wide range of issues that are important to his conservative Republican caucus, including government modernization, health care, public safety and economic development.

But he also denied 43 other requests including some sought by Democrats who fear they may have been rejected because they do not reflect the political goals of the GOP's House majority. Of those interim studies not approved, 25 were requested by Democrats.

Issues Democrats wished to explore include ad valorem tax support for community colleges, analyzing the cost of financing and building public schools, an analysis of the cost of inpatient and outpatient care for Oklahomans with autism and improving the emergency management fund that pays the cost of disaster recovery.

"I was disappointed that some of those subjects did not get covered in interim studies," said House Democratic Leader Danny Morgan of Prague, whose own interim study request to explore the possibility of creating satellite winery tasting rooms to help the state's fledgling wineries was rejected.

Morgan said he hopes political considerations were not behind the decisions to reject the Democratic requests.

"We've supplied them with an opportunity and they said: 'No!"' Morgan said. "We've got all of the fall to have a good bill come out."

An advocate for autistic children said political differences were clearly behind rejection of an interim study request by Rep. Terry Harrison, D-McAlester, who wanted to analyze the cost of inpatient and outpatient care for Oklahomans with autism and look at the costs of viable alternatives for treatment.

"The study will seek to find the best possible result for Oklahoma's autistic children and for Oklahoma's taxpayers." Harrison wrote in his request.

But Benge and other GOP House leaders have consistently opposed a health insurance coverage mandate for the diagnosis and treatment of autistic children, claiming it will drive up the cost of health insurance and make it unaffordable for many Oklahomans.

"There will not be any approval of these studies. We knew that going in," said Wayne Rohde, the father of an autistic child and the namesake for Nick's Law, an autism coverage mandate that has passed the Senate in recent years but been blocked by Republican House leaders.

"They don't want to have that. We will have that in the Senate, though," Rohde said.

Senate President Pro Tem Glenn Coffee, R-Oklahoma City, has approved 34 interim studies including two dealing with insurance coverage for autistic children sought by Democratic Sen. Jay Paul Gumm of Durant.

The studies will explore Oklahoma high-risk pool coverage of autism spectrum disorder diagnosis and treatment and how the state's economy would fare with autism insurance mandates.

Rohde said the New Jersey Legislature recently passed an autism mandate making it the 14th state in the nation to approve one. He said federal officials are also studying autism health insurance coverage.

"Oklahoma is going to be one of these states to be on the outside looking in," he said.

Benge rejected several interim study requests sought by Rep. Joe Dorman, D-Rush Springs, including one to study how emergency management funding for disasters is done in other states. But the speaker approved another request by Dorman to study the efficiency, effectiveness and cost of training rural firefighters.

"There has been a push to increase the amount of training required of volunteer firefighters," Dorman said. "I would like to look at these potential requirements officially and get the firefighters' perspective."

Benge also rejected several requests by Rep. Richard Morrissette, D-Oklahoma City, including a comprehensive look at domestic violence and child endangerment intervention by using court-ordered judicial danger assessment reviews.
