U.S. Government Ends The Sinking Of Old Ships as Artificial Reefs

U.S. Government Ends The Sinking Of Old Ships as Artificial Reefs: " MARAD's new policy excludes from artificial reefing consideration of any vessel that was built before 1985 (and likely to contain PCBs). PCBs are a persistent toxic chemical family that is described by the U.S. EPA as potentially carcinogenic to humans and builds-up in the marine food chain. They are banned from use and production under the U.S. Toxic Substances Control Act."

Sinking fate of HMCS Annapolis destroyer generates environmental concern - The Globe and Mail:

 "“We haven’t seen anything from the province that shows us the ship has been cleaned. The people in Howe Sound are not confident it is clean,” he said, expressing concerns that polychlorinated biphenyls, mercury and other contaminants might be released from the sunken hulk."

A thousandfold increase in PCB levels and millions of dollars lost, the real cost of artificial reefs

A report  by the Basel Action Network highlights the environmental risks and economic losses caused by artificial reefing. In one reef, the total PCB concentrations in fish samples increased 1,446% on average from pre-sinking to postsinking"

"Study of the sunken Ex-USS ORISKANY, reveals startling toxic PCB
leaching from the sunken aircraft carrier. According to the data, the leaching is occurring
at more than twice the Navy’s and EPA’s presinking modeled expectations of 2006. In fact, leaching PCBs from the sunken vessel has been taken up by fish at the reef site at levels above the Florida Department of Health fish consumption advisory threshold. Total PCB concentrations in fish samples increased 1,446% on average from pre-sinking to postsinking"

MARAD change in policy scuttles sinking of USS Kawishiwi

A planned artificial reef of the USS Kawishiwi has been cancelled following the U.S. Maritime Administration (MARAD) 's decision not to sink ships made prior to 1985 due to concerns about PCB's.

'"The vessel, which is docked in Suisun Bay, was withdrawn from the list of ships after MARAD announced that it had revised its policies and the Kawishiwi will now be part of the ship recycling programme. The agency is now excluding all ships that are likely to contain Polychlorinated Biphenyls (PCBs)."

MARAD has offered a replacement ship which meets the new standards.

The CEO of California Ships to Reefs, Joel Geldin said: “We have always made ocean safety the top priority in our reefing plans and we’re willing to move forward with MARAD, working with whatever standards they require.”

U.S. Government Ends The Sinking Of Old Ships as Artificial Reefs

Recognizing the potential environmental impact and loss of economic revenue, the Obama administration has made significant chances to the federal  artificial reefing program 

"The U.S. Maritime Administration (MARAD) has adopted a new policy that effectively terminates the federal artificial reefing program that allowed the scuttling of old ships for so-called "artificial reefs" – a practice that dates back to the Liberty Ship Act of 1972. Since the program's inception, approximately 45 ships have been disposed of at sea, along with untold tons of toxic substances such as polychlorinated biphenyls (PCBs) and heavy metals built into each vessel, as well as many millions of dollars-worth of steel and non-ferrous metal resources. "

Regulations leave anglers, boat captains frustrated | TuscaloosaNews.com

"Federal officials are hesitant to accept data collected from reefs off Alabama because the reefs are almost entirely artificial — objects sunk to create fish habitat. Some people debate whether the red snapper are actually reproducing on artificial reefs or if they are just attracted to artificial reefs, Anson said.
The ratio of red snapper to other fish is very high on artificial reefs.
“They're 95 percent of the fish on our reefs,” Anson said. “That's not what you would expect to find on a natural reef.”"

The Associated Press: AP ENTERPRISE: Navy 'Sinkex' raises pollution fear

The Associated Press: AP ENTERPRISE: Navy 'Sinkex' raises pollution fear:

PCB's found in fish near an aircraft carrier sunk in 2006 as an artificial reef near Pensacola, Florida have raised concerns about the impacts, although the ship was located much closer to shore and in much shallower waters than Sinkex vessels.

"Annual monitoring by the Florida Fish and Wildlife Conservation Commission of waters around the USS Oriskany concluded that fish around the carrier exceeded state and federal PCB standards in the first two years. Florida's PCB limits are 50 parts per billion for safe human consumption— EPA standards are 20 ppb. Fish later collected saw a drop in those levels overall, but some still exceeded the EPA and Florida standards."
