An explosion occurred at the petroleum storage facility in Bayamon, Puerto Rico around 12:30 AM October 23, followed by a large fire. The facility is inland, southwest of San Juan. The area was declared a disaster. Environmental concerns center on the marsh north of the facility, which was impacted by fire, petroleum from ruptured storage tanks, and run-off from firefighting actions. In addition, the marsh has been impacted by construction of new dikes and roads from firefighting. The spill response is being funded under the Oil Pollution Act. Felix Lopez, Contaminants Specialist from our Boqueron Field Office, is on scene. There are reports of oiled birds, turtles and an endangered Puerto Rican boa (Epicrates inornatus). Puerto Rico Department of Environmental Resources (DNER) has been collecting wildlife and taking them to their facility on the north coast. An emergency Endangered Species Act consultation for the response is complete, as is a response plan for federally protected wildlife. Petroleum recovery continues in the marsh with vacuum trucks and hand-applied sorbents. A preliminary assessment of the environmental impacts was conducted by the Environmental Protection Agency (EPA) and Puerto Rico's Environmental Quality Board (EQB), at the facility and its surroundings. It is estimated that about 33 acres of wetlands north of the facility are impacted. The total wetlands area north of the facility has been estimated to be about 70 acres. Other Agencies known to be involved at this time include: Federal Emergency Management Agency (FEMA), U.S. Coast Guard (USCG) and the Department of Transportation (DOT).

Exxon Mobil Corporation, whose oil and gas drilling and production facilities in 5 States were linked to the deaths of Federally protected birds, has pleaded guilty to violating the Migratory Bird Treaty Act. The company must pay $600,000 in fines and community service payments and implement an environmental compliance plan to prevent bird deaths at its facilities in Colorado, Wyoming, Oklahoma, Texas, and Kansas. The company has already spent $2.5 million to protect birds at these sites.

Thousands of fish died suddenly in the Rock River in northern Illinois on Sunday, June 21 st, 2009. Alarmed by the potential threat, contaminants biologists along with fish and wildlife biologists from the Ecological Services Field Office in Illinois immediately began to test the water for toxins. The Rock River supports federally listed endangered mussels and many kinds of migratory birds that use the river for nesting. Record rains and a train wreck with a spill of gasoline ready ethanol occurred on Friday before the fish kill. Biologists are inspecting the river beds containing endangered mussels and participating in an investigation to determine the cause of the fish kill.

Many of Washington State’s sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country, according to a study published by researchers from National Oceanic and Atmospheric Administration's Olympic Coast National Marine Sanctuary, the U.S. Fish and Wildlife Service and their partners.

While the Washington sea otters do not appear to be suffering negative effects from the pathogens, they still face potential threats from infectious disease due to their relatively small population size and limited distribution.

“Sea otters are a keystone species in the sanctuary, so potential disease threats are a significant concern for us,” said Mary Sue Brancato, a sanctuary resource protection specialist who is one of the study’s co-authors. “Changes in their population can affect the whole ecosystem.”

A recent study of intersex abnormalities in fish conducted by researchers from the U.S. Fish and Wildlife Service and the U.S. Geological Survey in the Potomac River watershed showed that at least 82 percent of male smallmouth bass and in 23 percent of the largemouth bass had immature female germ cells (oocytes) in their reproductive organs.

This condition, a type of intersex, is a disturbance in the fish’s hormonal system and is an indicator of exposure to estrogens or chemicals that mimic the activity of natural hormones. Several other abnormalities were also noted, some affecting female bass.

“At the moment we don’t know the ecological implications of this condition and it could potentially affect the reproductive capability of important sport fish species in the watershed,” said Leopoldo Miranda, Supervisor of the U.S. Fish and Wildlife Service’s Chesapeake Bay Field Office.
