Testing continues to assess prevalence of ciguatera toxin in lionfish in the Caribbean

February 3rd, 2012

LionfishNews from Cayman about a project to evaluate the risk of ciguatera poisoning associated with lionfish consumption:

A study to determine if Cayman’s lionfish carry the toxin that causes ciguatera poisoning is under way, but so far there have been no reports of humans contracting the illness from eating the invasive species.

Researcher Bill Davin, an associate biology professor at Berry College in Mount Berry, Georgia, has been examining lionfish samples supplied by the Cayman Islands to see if they contain the naturally occurring toxin.

He has carried out examinations on 20 lionfish from all three islands – 12 from Cayman Brac, two from Little Cayman and six from Grand Cayman.

“Only one of the fish extracts thus far has shown signs of bio-activity, but those levels were relatively low compared to previous research I have done on ciguatoxic fish,” he said.

St. Maarten’s Nature Foundation last year recommended lionfish not be eaten based on a study that found ciguatoxins in flesh samples of larger lionfish caught in the island’s waters.

A US Food and Drug Administration study in the Caribbean has also revealed presence of the toxin in the flesh of lionfish.

“To date we have received no official reports of illness associated with the consumption of lionfish, but in endemic areas of ciguatera, toxins have been detected at levels exceeding FDA guidance and therefore could cause illness if consumed,” said Pat El-Hinnawy, an FDA public affairs officer. “The Virgin Islands is one of those areas. We have collected more than 186 fish from the waters around the US Virgin Islands, including St Croix, St. Thomas and St. John, and Puerto Rico. Of these, we have tested 74 fish to date with 26 per cent confirmed to contain ciguatoxins at levels exceeding FDA guidance.

“Our testing continues in this and other regions,” Ms El-Hinnawy said. “These results are consistent with other species of fish that are well known to be ciguatera hazards in endemic areas.”

Mr. Davin said people eating lionfish should use the same precautions they use when eating other Caribbean reef fish that can carry the ciguatera toxin.

“Avoid fish taken from established or known ciguatera hotspots and if a person has already had ciguatera, they should certainly be more careful, since they are certainly at a higher risk of re-intoxification than someone that has never had the disease,” he said.

He added: “While the number of toxic lionfish being reported from St. Thomas and St. Maarten seem high, I have not been able to find a single report of anyone contracting ciguatera from the consumption of lionfish.”

After being hit with heavy environmental penalties, the Caribbean’s largest oil refinery is set to shut down

January 18th, 2012

HOVENSA logoThe controversy-plagued HOVENSA oil refinery, located in St. Croix, U.S. Virgin Islands is going to be shut down. Less than a year has passed since the refinery was hit with a fine of over US$5 million for air pollution infractions. It was also required to implement $700 million worth of pollution control measures and to set up a $4.875 million environmental project fund to benefit the Virgin Islands environment.

According to the Caribbean Journal, HOVENSA’s parent company says that the shutdown is the result of a downturn in the global petroleum market:

The HOVENSA oil refinery in St Croix, US Virgin Islands, will be shut down, the company announced today.

The refinery, which is one of the 10 largest in the world and the largest in the Caribbean, is a joint venture between the Hess Corporation and Petroleos de Venezuela SA.

Hess cited weakness in demand for petroleum products due to the global economic slowdown and the addition of new refining capacity in emerging markets as factors leading to the shutdown.

It also said the low price of natural gas in the United States had place HOVENSA at a “competitive disadvantage.”

The company said it had explored other options to keep the refinery operating, but financial losses “left it with no other choice.”

The US government has previously found the refinery to be in violation of its federal Clean Air Act, saying in August that there had been “too many chemical releases and other potentially dangerous incidents at the HOVENSA facility in recent years, including three in January 2011 alone,” according to EPA Regional Administrator Judith Enck.

It is not clear whether that played a role in the shutdown.

USVI sets ambitious new energy goals

January 13th, 2012

St. Thomas, USVIThe Governor of the U.S. Virgin Islands has announced a major new energy goal for the territory:

Like many islands on earth, the USVI are almost 100 percent dependent on imported oil for electricity. Residents pay about 47 cents per kilowatt hour to light their homes and run their appliances. Imported oil is even used to desalinate the water because there is so little fresh water available other than what residences catch on their roof in the form of rain water.

But USVI Gov. John P. de Jongh Jr., working with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and the U.S. Department of Interior, has vowed to transform energy use dramatically. In January, at his State of the Territory address, he announced the goal of reducing use of fossil fuels by 60 percent in the next 15 years.

That’s huge, and a great challenge, and just possibly a blueprint for how to achieve those similar reductions on the mainland.

“What we’re attempting to do is integrate every large portion of renewable energy into our system,” said Karl Knight, the director of USVI’s energy office, who also is a board member of the Virgin Islands Water and Power Authority. Think of it as a pilot for how to integrate renewables as a large proportion of the grid.”

To get there, a half dozen different technologies need to be implemented, and energy efficiency will have to become a rallying cry.

The recipe to achieve a 60 percent reduction:
2 percent biomass
3 percent landfill gas
3 percent solar
6 percent wind
8 percent waste-to-energy
38 percent energy efficiency

New catch limits set to prevent overfishing in U.S. Caribbean waters

January 5th, 2012

Blue Tang, U.S. Virgin IslandsThe Pew Environment Group reports that the U.S. government has taken steps to prevent overfishing of certain key species in U.S. Caribbean territories:

Holly Binns, a project director for the Pew Environment Group, issued the following statement today in response to the U.S. Department of Commerce’s final approval of plans to prevent overfishing of 132 species by setting science-based catch limits. The Caribbean Fishery Management Council gave initial approval in August.

“These plans mark a major milestone in the decades-long effort to end overfishing of dozens of depleted species. The new rules will serve two purposes: help dwindling species recover, and assist in preventing overfishing from occurring by protecting relatively healthy species now before they potentially plummet to critically low levels. For the first time, fishery managers have the tools to more easily spot declines in fish populations and take action quickly to avoid reaching a crisis. This proactive approach should help reduce the establishment of severe fishing restrictions that become necessary when species are depleted.

“The new catch limits are reasonable and based on sound scientific recommendations. There is still much work to be done, however, to ensure that the new system is effective and limits are enforced. Overall, in a region where overfishing has taken a severe toll, these plans blaze a new path in managing fish that are vital for a healthy ocean ecosystem and coastal economy.”

These plans are formally known as the Comprehensive Annual Catch Limits Amendments. They were originally approved by the Caribbean Fishery Management Council in September 2010 and August 2011. The U.S. Secretary of Commerce has the final say in setting regional fishery policies. The plans cover 132 species ranging from Nassau grouper and parrotfish to angel fish and queen conch. The rules become effective Jan. 29.

Alcoa to clean up contaminated land in St. Croix, USVI

December 13th, 2011

Renaissance Park, St. CroixAfter six years of legal wrangling, Alcoa World Alumina and two other defendants have been assigned responsibility for remediation of a contaminated site in St. Croix:

More than six years after the V.I. Department of Planning and Natural Resources filed suit against eight industrial companies operating on the southern shore, a portion of the toxic red mud resulting from decades of alumina production will be cleaned up, officials said.

The cost of the clean-up is unknown, and the exact timeline is still unclear, subject to permitting and plan approvals. A recently lodged consent decree, however, mandates that the bill will be picked up by two of the defendants, while a third was designated as responsible for maintaining the site once work has been completed.

The clean-up will come at no cost to the V.I. government.

Instead, the government will have $3 million set aside in an escrow account to enforce and regulate the three defendants, which are the three most recent owners of the property: St. Croix Renaissance Group; Alcoa World Alumina; and St. Croix Alumina, which is a subsidiary of Alcoa.

Two other alumina defendants, V.I. Alumina Corp. and Lockheed Martin Corp., have not agreed to any settlement.

The two oil refinery defendants, HOVENSA and Hess Oil, also have not reached a settlement. The plaintiffs claim the refineries contaminated the groundwater separately from the red mud contamination.

The final alumina defendant, Century Aluminum, was released from the lawsuit last month after Bartle issued a judgement in its favor. Century Aluminum only owned the alumina plant for one day “through various maneuverings” and did not process any alumina during that day and did not contribute to the red mud, said attorney John Dema, who has been one of five attorneys listed as representing the V.I. government and DPNR.

The settlement agreement between DPNR and the V.I. government and the three alumina defendants in the “Red Mud” case, which has been in U.S. District Court since May 2005, has not yet gone into effect. District Judge Harvey Bartle III will have to sign off on the agreement, Dema said.

During a press conference Friday, V.I. Attorney General Vincent Frazer said the agreement is a significant milestone.

“We are pleased to report today that we have a partial settlement with some of the parties in the case,” Frazer said. “While not complete, it represents substantial progress.”

The pollution of what is known as the St. Croix Southern Industrial Complex began in the 1960s, when Hess Oil and Harvey Aluminum arrived and built industrial facilities, replacing what had once been land used for sugar cane production with an oil refinery and an alumina plant. Harvey Aluminum’s plans to build on the 1,400-acre property were approved by the V.I. Legislature in 1962. By the end of the decade, Martin Marietta Alumina had purchased a controlling interest in Harvey. Martin Marietta’s successor, Lockheed Martin, owned the plant outright by 1972, according to a memorandum in support of the consent decree filed by the settling parties’ attorneys.

Up until 1972, the red mud byproduct was being disposed of in a containment lagoon, now called “Area B” in court filings. Lockheed Martin said it closed down Area B in 1972 and began to move the red mud to a different site, called “Area A” in court documents.

V.I. Aluminum bought the site in 1989 and operated the plant until 1994, when it suspended operations. It moved red mud to Area A.

In 1995, St. Croix Alumina bought the site, though it did not resume operations until 1998. St. Croix Alumina also moved red mud only to Area A until it ceased operations in 2000.

Red mud is a chemical compound with a rusty pigmentation from a high concentration of iron oxide which results from producing alumina from bauxite. It can be radioactive and maintains a high pH balance, making it highly caustic, with the potential to leave severe burns. DPNR’s lawsuit arose from concerns that red mud had leeched into the aquifer, contaminating the sea and the mangrove swamps to the south and getting picked up by the wind and swept over communities to the northwest.

Some residents in the area claim to continually be cleaning up a red dust they believe comes from the site and to which they attribute some of their health problems.

“We are very glad to be able to bring some relief to the surrounding residents,” Barnes said Friday.

U.S.V.I electricity company seeks solar power

October 13th, 2011

A major electricity supplier in the U.S. Virgin Islands is looking to introduce solar-generated power into the national grid:

More than two-dozen companies responded to a request for proposals (RFP) by the V.I. Water and Power Authority to purchase solar photovoltaic generation from independent power producers, the utility announced.

WAPA’s bid process for the project closed [in September], and Executive Director Hugo Hodge Jr. said the utility received 27 bids.

“We are excited about the large number of respondents who have made submissions and are looking forward to diversifying our generating portfolio by adding renewables to the mix,” he said.

The authority is seeking photovoltaic generation to lower the cost of power production in the territory. The RFP said the utility will sign a 20-year power purchase agreement to procure electricity generated from solar energy from one or more selected companies with an option to renew for another five years. Winning bidders will be responsible for constructing, operating, and maintaining the projects.

WAPA is seeking a maximum of 10 megawatts of electrical capacity, allocating approximately five each to its generation facilities on St. Thomas and St. Croix.

Conservation organisation files suit to get corals declared as endangered species

October 6th, 2011

Staghorn coral, which is currently listed as threatened under the Endangered Species Act, observed in Carlos Rosaria Reef near Culebra, Puerto RicoIn the U.S., the Center for Biological Diversity recently filed a lawsuit seeking to expand the protection offered to coral reefs under the Endangered Species Act.

The lawsuit and corresponding settlement cover 82 species of coral, including eight species that are found in the Caribbean; if the Center achieves its objective, it would affect the conservation status of corals in Puerto Rico and the U.S. Virgin Islands.

Along with elkhorn and staghorn coral, numerous other species could get more protection under the Endangered Species Act as soon as next year pursuant to a settlement reached this week in a federal court.

Under the agreement, federal biologists will determine by April 15, 2012 whether Endangered Species Act protections are needed for 82 species of coral. All were part of a petition filed by the Center for Biological Diversity that asked the federal government to list the corals as threatened or endangered.

If listed, resource managers could take steps to protect the corals from activities like harmful fishing techniques, dumping, dredging and offshore oil drilling.

The corals, which live in U.S. waters ranging from Florida and Hawaii to American territories in the Caribbean and Pacific, have all declined by more than 30 percent in the past 30 years. Coral reefs around the world are facing extinction due to overfishing, pollution and the overarching threats of global warming and ocean acidification.

“Unless we protect them right now, coral reefs will be lost within decades, and our grandchildren will never see these colorful underwater forests teeming with life,” said Miyoko Sakashita, director of the Center’s oceans program. “The settlement is a victory for corals because it will speed efforts to reduce threats and protect coral habitat.”

The Virgin Islands Daily News reports:

The Center for Biological Diversity filed a lawsuit along with a settlement agreement Tuesday to have the federal government take the next step in including 82 species of corals on the endangered species list.

Eight of the 82 corals are found in V.I. waters. Under the agreement, the federal government has until April 15 to determine if each species warrants protection under the Endangered Species Act.

The petition stated that the eight Caribbean corals – Lamarck’s sheet coral, boulder star coral, mountainous star coral, star coral, pillar coral, elliptical star coral, rough cactus coral and large ivory coral – face multiple threats that include bleaching; disease; stronger hurricanes; and storms, pollution and sedimentation as a result of coastal development and chronic overfishing. In addition, all corals face a growing threat of extinction because of rising ocean temperatures caused by global warming and the related threat of ocean acidification, the petition stated.

You can find more information on the settlement and the lawsuit (which was filed along with the settlement agreement in order to make the settlement enforceable by the courts) in reports from the Summit County Voice, the Virgin Islands Daily News and at the website of the Center for Biological Diversity.

U.S.V.I Department of Forestry offers grants for urban and community forestry projects

October 4th, 2011

St. John, U.S. Virgin IslandsThe U.S. Virgin Island’s Department of Forestry is providing grants to support community-based forestry projects. The St. Thomas source reports:

Twice each year in May and November, the U&CF Program accepts proposals for forestry projects that encourage citizen involvement territory-wide. Over the years, the grant-awarded projects have provided educational as well as data-driven management recommendations, enabling greater stewardship of the territory’s forests in both urban and residential areas. I am pleased to announce this request for proposals and especially encourage new applicants or new community-based groups and organizations to apply,” Agriculture Commissioner Louis E. Petersen Jr. said.

Grant awards will be made on a competitive basis, and require a 1-to-1 match to the amount requested; matches may be met through in-kind donations and volunteer time. The deadline for proposal submissions for this grant cycle is Monday, Nov. 7.

The program seeks proposals for project funding from local government, nonprofit organizations, civic and/or educational organizations, including but not limited to schools, homeowners’ associations, service clubs and environmental organizations. The U&CF Program does not fund strictly agricultural projects. Projects must have a forestry component to be eligible for funding.

Proposals are requested in the following areas: education and public outreach on urban forestry; protecting and publicizing heritage and remarkable big trees; reducing forest health risks due to invasive species; identifying and managing hazardous trees; collecting data on wildlife use of urban forests; planning for and planting urban trees; training to become arborists; developing and implementing forest management plans for developed areas with urban forests; and writing tree guidelines for communities.
