As Price of Oil Soars, Users Shiver and Cross Their Fingers

http://is.gd/HQT2lh
When David Harris built his 2,000-square-foot hilltop home nine years ago, he wanted to put in natural gas, but the utility wouldn’t run a line to his house. Like many people here, he was stuck using heating oil.

Mr. Harris added a wood stove to help cut costs and now uses only about one-third of the oil the house would otherwise need. But that did not stop a deliveryman for Crowley Fuel from handing him a $471.21 bill earlier this month for a refill that should get him to April.
...
While natural gas prices have plummeted to 10-year lows, heating oil prices have been steadily rising for years and are expected to reach record levels this winter, precipitated by higher costs for crude oil and the shutdown of several crucial refineries in the Northeast and in Europe. The Energy Department projects a price of $3.79 a gallon over the next few months, more than a dollar above the winter average for the last five years. Analysts do not expect much relief in the longer term, either, because global oil prices are expected to stay high amid political instability in the Middle East and rising demand from developing countries.

With electricity prices also down, utilities are trumpeting that bills will drop this season for customers using gas and electric heat. Con Edison announced this week that residential gas heating bills in New York were expected to drop 11.5 percent this winter, and in New Jersey, PSE&G said that it would cut February bills for residential gas customers by an average of $30.

“The people who have been unable to switch off of heating oil will be increasingly penalized in the coming years,” said Jay Hakes, a former administrator of the Energy Information Administration and now the director of the Jimmy Carter Library and Museum....

Nationwide, the average household using oil spent $2,298 on heat last year, compared with $724 spent by gas users and $957 spent by electricity users, according to the Energy Department.

This year, heating oil users are expected to spend 3.7 percent more than last year, while natural gas customers are expected to spend 7.3 percent less and electricity users will spend 2.4 percent less, according to the department.

Cheap natural gas was part of the appeal for Gus Kontoudakis, who spent about $3,000 to switch from oil at the home he rents out in Plainfield, Conn. The boiler was due for replacement anyway, he said.
...
But many oil users — living in places like Alaska, Maine and even affluent parts of Manhattan — do not have that option. Some are simply too far from a pipeline. For others, converting to natural gas is unaffordable, with costs that can run to tens of thousands of dollars for each home. As a result, they are trapped in a cycle of spending more and more for heat while those who use natural gas and electricity are generally spending less and less.

That dynamic is at work in households across the economic spectrum, but the cost gap looms as a crisis for the poor, experts warn, since the federal government has cut financing for energy assistance programs.
...
The use of heating oil, which rose after World War II as a replacement for coal, has been on a long decline. As the use of virtually every other fuel has increased, the number of households that use heating oil has dropped from about 20 percent in 1975 to roughly 7 percent today, spurred by new home construction and population shifts to the West and South, closer to natural gas fields and pipelines. Government incentives for installing insulation also cut consumption of heating oil.

For decades, the prices of oil and gas moved virtually in tandem, but in recent years, vast increases in American gas supplies have made gas decisively cheaper.

Meanwhile, heating oil could grow more scarce in the Northeast this winter, the Energy Department warned last month. Companies have been closing refineries that produce heating oil because of declining profit margins. Sunoco and ConocoPhillips recently announced the idling of two major refineries in Pennsylvania, and a third refinery owned by Sunoco may close next summer.

Encouraged by the low prices for natural gas and government and utility incentives, more oil customers have been looking to make the switch.

Thomas Dziki of Richmond Hill, Queens, said it was a $750 bill to fill up his 150-gallon oil tank last winter that prompted him to call National Grid to convert. He spent about $8,500 to switch his three-story home to gas. Now, his monthly bills are in the $30 to $50 range ...

For larger buildings in New York City, there is increased pressure to switch because of a new pollution regulation that will phase out the use of the heavier heating oils.

But conversion costs can be prohibitive, in part because Con Edison, the local utility, has to rip up the street to run pipes larger than those used for cooking gas.

Nancy T. Schmitt, an energy-sector investment adviser whose Upper East Side co-op burns the densest form of oil.... But by one estimate, she said, it would cost $2 million to connect her complex to the existing lines. Con Ed has been working to help organize buildings into clusters for conversion, to lower costs and diminish the inconvenience.

UNEP Ogoniland Oil Assessment Reveals Extent of Environmental Contamination and Threats to Human Health - United Nations Environment Programme

http://www.unep.org/Documents.Multilingual/Default.asp?DocumentID=2649&ArticleID=8827
The environmental restoration of Ogoniland could prove to be the world's most wide-ranging and long term oil clean-up exercise ever undertaken if contaminated drinking water, land, creeks and important ecosystems such as mangroves are to be brought back to full, productive health.

A major new independent scientific assessment, carried out by the United Nations Environment Programme (UNEP), shows that pollution from over 50 years of oil operations in the region has penetrated further and deeper than many may have supposed. 

The assessment has been unprecedented. Over a 14-month period, the UNEP team examined more than 200 locations, surveyed 122 kilometres of pipeline rights of way, reviewed more than 5,000 medical records and engaged over 23,000 people at local community meetings. 

Detailed soil and groundwater contamination investigations were conducted at 69 sites, which ranged in size from 1,300 square metres (Barabeedom-K.dere, Gokana local government area (LGA) to 79 hectares (Ajeokpori-Akpajo, Eleme LGA). 

Altogether more than 4,000 samples were analyzed, including water taken from 142 groundwater monitoring wells drilled specifically for the study and soil extracted from 780 boreholes.

Key Findings:
Some areas, which appear unaffected at the surface, are in reality severely contaminated underground and action to protect human health and reduce the risks to affected communities should occur without delay says UNEP's Environmental Assessment of Ogoniland.
 
In at least 10 Ogoni communities where drinking water is contaminated with high levels of hydrocarbons, public health is seriously threatened, according to the assessment that was released today. 

In one community, at Nisisioken Ogale, in western Ogoniland, families are drinking water from wells that is contaminated with benzene- a known carcinogen-at levels over 900 times above World Health Organization guidelines. The site is close to a Nigerian National Petroleum Company pipeline. 

UNEP scientists found an 8 cm layer of refined oil floating on the groundwater which serves the wells. This was reportedly linked to an oil spill which occurred more than six years ago. 

While the report provides clear operational recommendations for addressing the widespread oil pollution across Ogoniland, UNEP recommends that the contamination in Nisisioken Ogale warrants emergency action ahead of all other remediation efforts. 

While some on-the-ground results could be immediate, overall the report estimates that countering and cleaning up the pollution and catalyzing a sustainable recovery of Ogoniland could take 25 to 30 years.
...
Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said the report provided the scientific basis on which a long overdue and concerted environmental restoration of Ogoniland, a kingdom in Nigeria's Niger Delta region, can begin.

"It is UNEP's hope that the findings can break the decades of deadlock in the region and provide the foundation upon which trust can be built and action undertaken to remedy the multiple health and sustainable development issues facing people in Ogoniland. In addition it offers a blueprint for how the oil industry-and public regulatory authorities- might operate more responsibly in Africa and beyond at a time of increasing production and exploration across many parts of the Continent," said Mr Steiner.

Among its other findings are:-
  • Control and maintenance of oilfield infrastructure in Ogoniland has been and remains inadequate: the Shell Petroleum Development Company's own procedures have not been applied, creating public health and safety issues.
  • The impact of oil on mangrove vegetation has been disastrous. Oil pollution in many intertidal creeks has left mangroves-nurseries for fish and natural pollution filters- denuded of leaves and stems with roots coated in a layer of bitumen-type substance sometimes one centimetre or more thick.
  • The five highest concentrations of Total Petroleum Hydrocarbons detected in groundwater exceed 1 million micrograms per litre (µg/l) - compared to the Nigerian standard for groundwater of 600 µg/l.
  • When an oil spill occurs on land, fires often break out, killing vegetation and creating a crust over the land, making remediation or revegetation difficult. At some sites, a crust of ash and tar has been in place for several decades.
  • The surface water throughout the creeks in and surrounding Ogoniland contain hydrocarbons. Floating layers of oil vary from thick black oil to thin sheens.
  • Despite community concerns, the results show that fish consumption in Ogoniland, either of those caught locally or purchased from markets, was not posing a health risk.
The report says that fish tend to leave polluted areas in search of cleaner water. However, the fisheries sector is suffering due to the destruction of fish habitat and highly persistent contamination of many creeks. Where entrepreneurs have established fish farms for example their businesses have been ruined by an "ever-present" layer of floating oil.
  • The Ogoni community is exposed to hydrocarbons every day through multiple routes. While the impact of individual contaminated land sites tends to be localized, air pollution related to oil industry operations is all pervasive and affecting the quality of life of close to one million people.
  • Artisanal refining (a practice whereby crude oil illegally obtained from oil industry operations is refined in primitive stills), is endangering lives and ultimately causing pockets of environmental devastation in Ogoniland and neighbouring areas.
Remote sensing revealed that in Bodo West, in Bonny LGA, an increase in artisanal refining between 2007 and 2011 has been accompanied by a 10% loss of healthy mangrove cover - or over 307,380 square metres.
  • Remediation by enhanced natural attenuation (RENA) - a way of boosting the ability of naturally-occuring microbes to breakdown oil and so far the only remediation method observed by UNEP in Ogoniland - has not proven to be effective.
Currently, SPDC applies this technique on the land surface layer only, based on the assumption that given the kind of oil concerned, factors such as temperature and an underlying layer of clay, hydrocarbons will not move deeper. However, in 49 cases UNEP observed hydrocarbons in soil at depths of at least 5 m.

Next Steps/Recommendations
Through a combination of approaches, individual contaminated land areas in Ogoniland can be cleaned up within five years, while the restoration of heavily-impacted mangrove stands and swamplands will take up to 30 years. 

However, according to the report, all sources of ongoing contamination must be brought to an end before the clean-up of the creeks, sediments and mangroves can begin. 

The report recommends establishing three new institutions in Nigeria to support a comprehensive environmental restoration exercise. 

The report outlined $1,012,448,650 in preliminary estimated costs as follows
1. Emergency Measures (80 % for providing alternative drinking water to communities with contaminated water supply) - $63,750,000
2. Clean up of Land contamination - $611,466,100
3. Clean up of Benzene and MTBE Contamination and Nsisioken Ogale - $50,000,000
4. Clean up of Sediments - $20,000,000
5. Restoration of Artisanal Refining Sites - $99,452,700
6. Mangrove restoration and rehabilitation - $25,500,000
7. Surveillance and Monitoring - $21,468,000
8. Ogoniland Restoration Authority - $44,000,000
9. Center for Excellence in Restoration - $18,600,000
10. Alternative Employment to those in Artisanal Refining - $10,000,000
11. Third party Verification and International Expert Support to implementation recommendations @ 5 % - $48,211,840

The final clean-up costs are likely to be different, indeed much higher, for the following reasons:
1. Full environmental restoration of Ogoniland will be a project which will take around 25-30 years to complete, after the ongoing pollution has been brought to an end. The current cost estimates are operational costs of the new institutions over the first five years.
2. The clean-up costs for contaminated soil, a key component of the overall costs, will depend substantially on the remediation standards set. A more stringent standard will lead to higher
clean-up costs.
3. The cost of clean-up of groundwater is not included in this costing (except for Nsisioken Ogale). The clean-up objectives, standards and target will first need to be decided before a volume estimate and associated costing can be attempted.
4. No estimate is given for the clean-up of surface water. It is assumed that once the ongoing input of oil into the surface water is stopped, natural process will flush the floating oil. However, in locations where there is not enough water exchange, intervention will be needed for the clean-up.
5. The response and clean-up costs for any new spills, or newly discovered spills, simply cannot be estimated
6. Land will need to be leased to establish the Integrated Contaminated Soil Treatment Centre and mini treatment centres in situ. The cost of land acquisition is not included.
7. The report recommends a set of asset integrity actions for the oil industry, which include better securing of the facilities and proper decommissioning of abandoned facilities. These costs also are not included above.
8. A major cost item will be the restoration of mangroves and forests within the creeks around Ogoniland. The current estimates are limited to a pilot area of impacted mangroves and forests around the Bodo West oil field facilities.
