WASHINGTON — House members clashed Tuesday over a White House plan that essentially calls for zoning the oceans, with Republicans charging that it already has created more job-killing bureaucracy and Democrats saying it could give Americans more certainty on how they can use busy public waters.

“It has the potential to stunt economic growth and the jobs associated with that growth,” said Rep. Doc Hastings, R-Wash., chairman of the House Natural Resources Committee.

Rep. Ed Markey, of Massachusetts, the top-ranked Democrat on the panel, likened the idea — formally known as marine spatial planning — to making plans for air space.

“Opposing ocean planning is like opposing air-traffic control,” he said.

Hastings, who represents an agricultural district, said he feared that the ocean-planning process ultimately could lead to new regulations on lands adjacent to rivers and watersheds that drain into the ocean.

“For example,” he said, “a farmer working hundreds of miles from the coastline could be at risk of a new layer of regulatory review based on the ocean.”

At a committee hearing Tuesday called by Hastings, business groups assailed the proposal, and an official with the U.S. Chamber of Commerce accused the White House of trying to promote the plan with little fanfare, even though it could have a big impact.

“From my vantage point, the national ocean policy is the most significant issue affecting energy security, job creation and economic growth that no one has heard about,” said Christopher Guith, the chamber’s vice president for policy.

Urging the White House to back away from the plan, Guith said the proposal would have a “plethora of impacts on the country” and add “yet another maze of real or de facto regulation for businesses to attempt to navigate.”

“At a time of anemic economic growth and persistently high unemployment, the country is looking to its leaders to reverse these trends,” Guith said.

Rep. Sam Farr, D-Calif., said the U.S. must do better planning for its waters to reverse its “current destructive path.” He called the current situation “a bureaucratic mess,” noting that more than 140 federal laws and dozens of agencies have jurisdiction over ocean space.

“The terrifying fact is … that our ocean economy is at risk,” Farr said. “Just this summer, a growing 83-mile dead zone in the Chesapeake Bay was described by scientists as the worst in history.”

Hastings said he called the oversight hearing because President Barack Obama acted without congressional approval when he created a task force to come up with new policies to manage the oceans and the nation’s coastlines. And he said the president’s new “tangled web of bureaucracy” is sure to lead to White House requests for more federal spending.

But most alarming, Hastings said, is “the mandatory ocean zoning ordered to be imposed.”

“Disguised with the label of coastal marine spatial planning, ocean zoning could place huge sections of the ocean off-limits to activities not zoned as government-approved,” Hastings said.
