ALBANY — Gov. Andrew M. Cuomo’s administration is pursuing a plan to limit the controversial drilling method known as hydraulic fracturing to portions of several struggling New York counties along the border with Pennsylvania, and to permit it only in communities that express support for the technology.

ALBANY — 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.
