The state’s Health Department found in an analysis it prepared early last year that the much-debated drilling technology known as hydrofracking could be conducted safely in New York, according to a copy obtained by The New York Times from an expert who did not believe it should be kept secret.
The analysis and other health assessments have been closely guarded by Gov. Andrew M. Cuomoand his administration as the governor weighs whether to approve fracking. Mr. Cuomo, a Democrat, has long delayed making a decision, unnerved in part by strident opposition on his party’s left. A plan to allow a limited amount of fracking in the state’s Southern Tier along the Pennsylvania border is still seen as the most likely outcome, should the drilling process receive final approval.
