Three reasons Cape Cod (and Middleboro) air sucks

As Ben Wright, an advocate at Environment Massachusetts said:

“The least polluting, cheapest energy is the energy we never have to produce in the first place”

Interesting stuff below highlighting where poor air quality comes from.

Who ever thought SEMASS was such a Big Producer, impacting our air quality?

Three reasons Cape Cod air sucks
Power plants to the west of Cape Cod are the largest industrial sources of greenhouse gas emissions linked to climate change in the state, according to new data from the U.S. Environmental Protection Agency (EPA).

MetroWest News offers a list of the state's worse polluters, and three of the worse are downwind from Cape Cod.

SEMASS Resource Recovery Facility, Wareham, a 95-acre facility which burns trash collected by about 60 cities and towns in southeastern Massachusetts and Cape Cod to generate power.

Dominion’s Brayton Point plant in Somerset (just over the Braga Bridge in Fall River) pumps out 5.8 million metric tons of the gas a year.

Cape Cod Canal Power Plant Unit #1 is representative of the most efficient fossil fueled plants of the 1970 era. It's an oil fueled super-critical steam unit optimally designed to best operate between half load and full load.

Power plants throughout eastern Massachusetts are the largest industrial sources of greenhouse gas emissions linked to climate change in the state, according to new data from the U.S. Environmental Protection Agency (EPA).

The information comes from a website the EPA unveiled in January, publicly detailing for the first time emissions reported by the largest producers of carbon dioxide and related greenhouse gases in nine major industries.

All the top 10 sources of carbon dioxide emissions in the Bay State are power plants, including natural gas-fired facilities in Salem, Weymouth, Bellingham and Cambridge. The largest single producer of greenhouse gases in New England is the Brayton Point power station in Somerset, which is largely fueled by coal.

Similarly, the data shows power plants are the largest direct source of greenhouse gases nationwide.

Several owners defended local facilities, saying they take steps to be environmentally responsible, are highly efficient in meeting energy needs or turn waste into energy.

“It’s not a surprise that where you burn fossil fuel to make into electricity that is used every day to make our life a little better, you’re going to see carbon dioxide emissions,” said Jim Norvelle, a spokesman for the power company Dominion.

Dominion owns Brayton Point and the Salem Harbor power station, also one of the top 10 sources of greenhouse gases in the state. The Salem plant is set to close in 2014.

Norvelle noted there are no federal controls on carbon emissions, but Massachusetts is one of nine northeastern states that require power plants in the region to buy emission allowances. States use the proceeds help fund renewable energy initiatives.

Ben Wright, an advocate at Environment Massachusetts, said the new data from the EPA can help further develop the state’s plans to tackle carbon emissions.

“More data means we know better how to curb our greenhouse gas emissions,” he said. “You can’t reduce what you haven’t measured.”

The EPA’s new greenhouse gas inventory covers facilities that produce upward of 25,000 metric tons of carbon dioxide per year. That does not include emissions from agricultural operations, nor small-scale sources that add up, such as cars and trucks.

But the data from 2010 represents the vast majority of greenhouse gas emissions in the U.S., the EPA said. The agency said it was required to collect the data, which is from 2010, under a 2008 federal law.

The data can help businesses track and compare emissions in order to find efficiencies and inform state and federal environmental policy, the EPA said.


The agency is expected to propose limits on greenhouse gas emissions from new or upgraded power plants some time this year.

Overall, Massachusetts fared far better than much of the U.S., ranking 40th out of the 50 states and Washington D.C. in total carbon emissions. The five states with the highest emissions were Texas, Indiana, Ohio, Pennsylvania and Florida.

Wright said Massachusetts has made headway in reducing emissions. In addition to participating in the Regional Greenhouse Gas Initiative, the state Green Communities Act set a goal of getting at least 25 percent of the state’s power from renewable sources by 2030. It also established energy efficiency initiatives to cut power use.

“The least polluting, cheapest energy is the energy we never have to produce in the first place,” Wright said.

The state Global Warming Solutions Act also calls for cutting greenhouse gas emissions 25 percent below 1990 levels by 2020, Wright said.

Here’s a look at some of the largest producers in the state:

Fore River Station, Weymouth

The Fore River power plant generates about 787 megawatts of power, according to its owner, Constellation Energy. It is the third highest direct source of greenhouse gas emissions in the state, producing 1.6 million metric tons of carbon dioxide in 2010, according to EPA data.

SEMASS Resource Recovery Facility, Wareham

This 95-acre facility burns trash collected by about 60 cities and towns in southeastern Massachusetts and Cape Cod to generate power.

Owner Covanta Energy, which also runs three other waste-to-energy plants in the state, views its operation as a type of renewable energy. SEMASS manages about 1 million tons of waste per year, said Covanta spokesman James Regan.

The SEMASS facility produced about 890,000 metric tons of carbon dioxide in 2010, according to EPA data. Covanta officials pointed to EPA studies indicating that waste-to-energy operations are a low source of carbon emissions nationwide.

Overall, carbon emissions from waste-to-energy plants are about half that produced by coal-burning plants, said Mike Van Brunt, Covanta’s director of sustainability. The process further cuts emissions by keeping trash out of landfills, where it produces methane, another greenhouse gas, he said.

“For every ton of waste we keep out of a landfill, we prevent all of the methane generation,” Van Brunt said.

The operation also recycles metals that otherwise would have to be mined anew, Regan said.

Salem Harbor

The Salem Harbor power station generates about 745 megawatts, enough to power about 186,000 homes, according to Dominion. The plant sits on 65 acres on the city waterfront.


The facility produced 1.3 million metric tons of carbon dioxide in 2010, according to the EPA data. That is far less than Dominion’s Brayton Point plant in Somerset, which pumped out 5.8 million metric tons of the gas the same year.

The facility uses three coal-fired generating units and one fueled by oil. Dominion is shutting down the plant and already closed two of its coal-burning units in December. The facility will close altogether in June 2014.

Norvelle said the company has made no plans for the future of the site. City officials have pressed Dominion to clean up the site.

Kendall Cogeneration Station, Cambridge

The Kendall Cogeneration Station has a production capacity of 256 megawatts, according to its owner, GenOn Energy.

The First Street facility produced roughly 717,000 metric tons of carbon dioxide in 2010, according to EPA data.

The facility uses natural gas as its primary fuel, with oil as a backup. The plant produces two forms of energy — electricity and steam, which is sold for heating and cooling, according to GenOn.

The company is constructing a new steam line allowing it to sell commercial steam to downtown Boston, said GenOn spokeswoman Paige Kane.
