Thirty businesses on Long Island will share more than $5.2 million in state aid for building projects, worker training and new equipment.

The money is part of $62 million awarded by Gov. Andrew M. Cuomo to 101 local projects aimed at creating jobs.

When Cuomo announced the 2016 Regional Economic Development Councils’ awards in Albany last week, attention was focused on big developments such as the restoration of a fish and wildlife habitat along Mud Creek in East Patchogue, more work at the Wyandanch Rising blight removal project and pedestrian bridges at the Nassau Hub.

Each received more than $1 million.

Still, private companies also received substantial sums in the contest.

Qosina Corp., a supplier of parts to manufacturers of medical devices, received $185,000 toward the construction of a larger “clean room” at its Ronkonkoma facility.

The $955,400 room “maintains the cleanliness of the parts” through a controlled atmosphere that reduces particle count, said company founder and president Stuart Herskovitz. He said the project would boost sales.

Qosina also won $86,130 for training 70 of its 102 employees to use the specialized room. Another 10 jobs will be created within three years, according to Gerry Quinn, the company’s chief operating officer.

Defense contractor GKN Aerospace secured $500,000 toward the purchase of $4.2 million in equipment for its Amityville factory. The machinery will increase efficiency and capacity in the operation.

GKN also received $39,400 to train 298 of its 343 employees. A company spokesman didn’t immediately respond to a request for comment on Monday.

The state also backed a multimillion-dollar expansion by Sheltair Aviation at Republic Airport.

The private aviation company, based in Fort Lauderdale, Florida, plans to build six hangars at the East Farmingdale airport. A state grant of $200,000 will go toward installing water and electric lines on the property along with sewer and drainage systems.

Once all the hangars are in use, Sheltair and its tenants will employ between 200 and 250 people, up from about 50 now.

“This will help keep us competitive with other airports,” said Todd Anderson, Sheltair’s senior vice president of real estate and development. “We very much appreciate the state recognizing this as a regionally significant project and the need for infrastructure improvements at the airport.”
