Hartford - The Malloy administration unveiled the full details Friday of its shock diet for state government, a $1.6 billion budget-chopper that slashes social services, tourism and numerous other programs while jettisoning thousands of state employees.

The only way to rescind the cuts and stop the pain, the governor's staff said, would be reaching a new labor concessions agreement with the 15 state unions that rejected a deal last month.

"But that's up to them. It's not something the governor is planning on having happen," Roy Occhiogrosso, the governor's senior adviser, said. "At this point, this is the budget we have."

The 111 pages of Gov. Dannel P. Malloy's so-called Plan B proscribe spending cuts that touch nearly all levels of state government.

It closes the Old Saybrook DMV branch and four others, shutters bathroom facilities at all seven non-commercial highway rest areas, ends Connecticut River ferry service, cuts funding to the Mystic Aquarium and Garde Arts Center, and suspends athletics and arts programs for students of Connecticut's 17 technical high schools, including those in Norwich and Groton.

In all, 6,560 union and nonunion positions would be eliminated from state government. After considering vacant positions and retirements, about 4,328 of those cuts are actual layoffs.

About 1,000 pink slips had been sent out as of Friday, with more to follow over several weeks. With Malloy in Salt Lake City for a National Governors Association conference, his staff submitted the plan Friday morning to leaders of the General Assembly.

A unions spokesman was dismayed Friday by the size and scope of the governor's layoffs and cuts, which he said will harm the quality of life for all Connecticut residents. He called on Malloy to ditch Plan B and work with the State Employees Bargaining Agent Coalition to avoid such an apocalyptic outcome.

"This alternative is mutual assured destruction," coalition spokesman Matt O'Connor said of the governor's unveiled plan.

On Monday, union leaders representing 45,000 state workers may consider amending their coalition bylaws for contract votes. Malloy says he won't restart talks unless the unions loosen their requirement that 14 of 15 unions and 80 percent of members approve a deal.

The failed deal garnered only 57 percent of the vote.

But union leaders may lack the authority next week to make the changes. It requires 30 days prior written notice to amend the coalition bylaws, and Monday could be considered almost a week premature.

The governor's plan calls for saving $26.5 million a year by capping pay increases at 1.5 percent for state workers whose union contracts expire next year.

And it eliminates funding for the casino bus that transports low-income residents of Hartford County to work in the Foxwoods Resort Casino and Mohegan Sun.

Train fares will increase 14 percent on Shoreline East and 15 percent on Metro-North.

Weekend service on Shoreline East will discontinue beginning in November. Statewide bus service will be cut, and Dial-A-Ride will end for individuals who aren't disabled.

The new train fares would be the first price increases on both lines since 2005, and tickets would still be cheaper than New York's, officials said. Benjamin Barnes, the governor's budget chief, noted that train service will remain heavily subsidized by the state of Connecticut even with the higher fares.

Some areas of the budget were saved from cutbacks, such as municipal aid and parks. Barnes said that closing parks doesn't pass the administration's cost-benefit test.

"We felt that the additional savings of putting the gate down is not very great and the public harm is quite considerable," the budget chief told reporters. "If you don't have money to take a vacation this summer, you can still go to a park and take a swim and have some level of recreation."

The legislature can decide to call itself into session to put a stop to any part of the plan by Aug. 31, which is the deadline for ratifying a new agreement between Malloy and the unions, if one develops.

Legislators also could organize a public hearing by Aug. 15.

"For anyone who thought that there is an endless amount of government spending that can be cut without hurting the quality of life of Connecticut residents, this is obviously a wake-up call," said Senate President Donald Williams Jr., D-Brooklyn. "That said, the leaders understand that this is Gov. Malloy's only option, given the failure of [the unions] to ratify the labor concessions."

Occhiogrosso said that if lawmakers chose to restore funding, they'll have to offset any restorations with new cuts. "Like the governor and the lieutenant governor have said repeatedly, there aren't any good options. It's not like there's a big pot of money somewhere," he said.

Malloy's plan incorporated suggestions from the heads of state departments and agencies. The guiding principle was to reduce spending rather than eliminate programs outright. The facilities slated to close generally have the lowest use rates.

"Programming that exists in a diminished level is better than no programming at all," Barnes said.

The governor wrung hundreds of thousands of dollars in savings by cutting back security at some state buildings and turning down thermostats. Reducing the frequency of office cleanings is projected to save nearly $300,000 a year.

The plan also sets a new $25,000 family asset maximum for recipients of an expanded Medicaid program for low-income adults. State officials said the new rule would reduce the number of participants, such as college students, saving $30 million a year for state government.

While the parking lots of highway rest areas will remain open, their facilities and restrooms will soon close. This change will affect the North Stonington rest area and visitors' center along Interstate 95. State officials said they have no plans to install portable toilets.

"There's a lot of pain here, no question about it," Occhiogrosso said.
