The Hospital Corporation of America yesterday temporarily withdrew its application to build a $36.6 million hospital in western Fairfax County, near the Fair Oaks mall, saying it wanted another 30 days to review the situation.

"We've had our health planners in here for the past six weeks, and they've come across several things that have given us cause for pause," said Hospital Corp. spokesman Milt Capps. "There has been a lot of inadvertent health planning in Northern Virginia in the past. Nobody wants a miscue."

He said the profit-making organization has no plans to withdraw its hospital proposal. Capps said Hospital Corp. wanted more time to consider alternate locations and other factors.

The firm is concerned about rezoning in western Fairfax that is supposed to limit development in the Occoquan River Basin area, if not overturned in court.

Hospital Corp. has been in fierce competition with the not-for-profit Fairfax Hospital Association and another private profit-making hospital chain to build a new hospital in the rapidly growing area.

The Health Systems Agency of Northern Virginia, a regional planning agency, recommended that the state health commissioner reject the association's request for a certificate of need, which must be awarded before a new hospital can be built.

The agency was scheduled to hold hearings on the Hospital Corp. proposal on April 4, though the agency is expected to agree to the 30-day delay.
