Air Pollution:

Beyond The Clean Air Act

Monday, Sep 15
Center for Business and Industry, 18th/Callowhill Sts, Rm 2-28

Marilyn Howarth MD spoke on air pollution to the Sierra Club on Monday September 15 at the Center for Business and Industry, 18th and Callowhill Streets. She directs the Center for Excellence in Environmental Toxicology (CEET) at Penn, one of 21 environmental health centers around the US funded by the National Institute of Health (NIH). CEET studies the effects of pollution on cells, children, lungs and genes.

In 1952 a fog of particulates, sulfur dioxide and nitrogen oxides caused chiefly by coal used to smelt iron settled on London. A temperature inversion kept it from moving for two weeks. Many died. Howarth could not remember such an event in Philadelphia. On an air pollution index we are always below 200. China is above 400 every day except during the Olympics.

Air pollution causes cancer, heart disease, and lung diseases including asthma. In parts of Philadelphia 21-27% of people have asthma, one of the highest rates in the US, where the average is 9.3%

Regulation of the air in the US began in 1970 under the Nixon administration with passage of the Clean Air Act (CAA), which established the National Ambient Air Quality Standards for six criteria pollutants with known health effects: ozone, particulates, sulfur dioxide, nitrogen oxides, carbon monoxide, and lead. At the time lead was still in gasoline. Ozone is formed by nitrogen oxides, volatile organic compounds and sunlight. In the stratosphere ozone protects us from cancer-causing UV radiation. At ground level ozone irritates the lungs. Originally scientists tracked large particulates but could discover no correlation with disease. Only later did they find it was fine particulates, 2.5 microns or less long, that influenced health.

In yearly state implementation plans, states are required to enforce criteria pollutant standards set by the Environmental Protection Administration (EPA). If they didn't EPA could take away federal money allocated to them for highway construction, but EPA has never done this.

The CAA amendments of 1990, passed under the George HW Bush administration, added 187 hazardous chemicals to the criteria pollutants as substances EPA can regulate. They include benzene, common near highways, and formaldehyde, common along the Gulf of Mexico. The amendments also required companies to prepare risk management plan for disasters.

Transportation, both on-road (trucks) and off-road (trains, ships, planes), emit 65% of hazardous air pollutants in PA, 68% in NJ. Transportation and power plants are the main sources of PM 2.5.

in 2001 the American Trucking Association sued EPA, claiming the agency should have considered the cost of its regulations. A unanimous US Supreme Court said no cost-benefit analysis was required and air pollutants could be regulated as health hazards.

Why isn't our air cleaner?

  1. Some dirty air floats in from abroad. 8% of CA's air pollution is from China.
  2. EPA hasn't set standards for many hazardous air pollutants.
  3. Standards for criteria pollutants, especially ozone PM 2.5, are lax.
  4. Enforcement is left to states and is discretionary. Power plants and refineries are exempt. States seek compliance with no sense of urgency, rather than enforce the law.
  5. President Obama's new rule requires only an average reduction of power plant carbon emissions of 30%. Some plants may not have to change.
  6. There are no federal indoor air quality standards, though commonly used cleaners and pesticides contain carcinogens and any chemical spread by an aerosol is sure to enter the lungs.

Howarth would like electricity to be generated from fuels other coal but doesn't think the US has the political will to build enough wind, solar, or geothermal installations to take its place. She favors nuclear energy. The number of people injured by a coal-burning power plant rivals the number injured by a nuclear accident.

Someone pointed out the School Reform Commission will not allow NIH to measure the indoor air quality of Philadelphia school buildings. Howarth said many schools have mold.

The Wind Debate

On Monday June 9 about 45 people listened to three speakers on wind energy. The event was sponsored by the Sierra Club and CCP Coalition for a Sustainable Future at the Center for Business and Industry, 18th and Callowhill Streets.

Laura Jackson, a retired high school environmental science teacher from Bedford County and long-time Sierra Club member, was generally critical of industrial wind turbines as they are now constructed. They kill birds and bats, fragment forests, increase impervious surface and stormwater runoff, and generate low-frequency noise and shadow flicker. The last is rapid change from light to dark as blades pass before the sun. New designs like oscillating metal plates on a rooftop may mitigate these problems.

PA has about 700 windmills. New ones are up to 550' high from the ground to vertical tip. They sit on a base of reinforced steel and concrete that may be 10 deep and 60 across. Big wind turbines have a nameplate capacity of 2.5 megawatts, but most generate just 25% of that capacity because PA wind isn't strong. We rank 30th out of 50 states for wind potential. Coal-burning power plants often reach 75% of capacity. It could take 2,500 windmills to replace one such plant.

Jackson was especially critical of plans to build industrial wind turbines on Stone and Jack's Mountains in Mifflin County, in a flyway used by golden eagles and other raptors. When a bird swerves to avoid a wind turbine it leaves behind the updraft a mountain generates, forcing it to flap its wings to stay aloft. This uses up vital body energy. Jacks Mountain is recognized as core forest habitat and home to the state threatened Allegheny woodrat. it is also an important habitat for the timber rattlesnake, a species of concern in PA, and contains high quality watersheds that will be degraded by the construction of up to 95 wind turbines on the top of these very steep mountains.

Industrial wind turbines generate relatively few jobs per project. One project of 60 needs 11 maintenance workers. In the question period afterward a listener said coal mining generate far fewer jobs than it once did.

Phil Wallis, executive director of Audubon PA, said 30% of birds have lost at least half their habitat because of global warming. There should be no offshore windmills in less than 50' of water, over which shorebirds fly.

The effects of windmill-caused forest fragmentation haven't been studied, but they are likely to parallel those of drilling-caused forest fragmentation, which have been studied. Birds living on the edge of the forest will do better than those living in the forest interior.

Rooftop solar has lately become cheaper. Installers now offer better financing until electricity savings pay for the panels. Because it is less disruptive to the environment and less threatening to wildlife, solar is the preferred form of renewable energy, at least until windmills are redesigned.

The Delaware and Schuylkill

River Sojourns

Monday, April 21st

Presented by the Sierra Club of Southeastern PA and CCP Coalition for a Sustainable Future: Our speakers are Richard Egan of the Delaware River Sojourn and Tim Fenchel of the Schuylkill River Sojourn. Each June hundreds of people paddle down the Delaware and Schuylkill Rivers in kayaks or canoes. The full trip takes seven days although most people stay just one or two days. For adults the cost is $80-85 per day. Kids and people without paddling experience are welcome.

Rich Egan, chair of the Delaware River Sojourn, spoke. The 2014 event starts at the Zane Gray house in Lackawaxen PA in Pike County and ends at Neshaminy State Park in Bucks. In between people paddle about 70 miles and ride by car or bus the rest of the way. At night they camp in riverside parks if they choose. Breakfast, lunch and some dinners are included as is boat rental.

Tim Fenchel spoke for the Schuylkill River Sojourn. It starts at Schuylkill Haven in Schuylkill County and in seven days covers 112 miles, all by boat, ending at Boathouse Row in Philadelphia. Meals camping fees, and boat rental are included.

The 2014 Schuylkill Sojourn is scheduled for Saturday June 7 - Friday June 13. The Delaware Sojourn is Sunday June 22 - Saturday June 28.

The Delaware Sojourn costs $560 for all seven days, but kids under 21 pay half price, and first-time Sojourners get a $25 discount.

Fees charged boaters don't cover costs, so both Sojourns rely on grants from the state and supportive organizations. They also hold fundraisers.

The first few days of the Delaware and Schuylkill Sojourns are the most popular. The Delaware starts with 100 people and ends with 40. The Schuylkill starts with 120, ends with 80. Altogether 225-300 people participate in each Sojourn. The first three days of the Schuylkill Sojourn are already sold out.

The Schuylkill Sojourn and the Schuylkill River Trail are projects of the Schuylkill River Heritage Area, one of five national heritage areas in PA. Others are Rivers of Steel, Oil, Delaware and Lehigh River, and Lackawanna.

At the end there are buses to take people back to their cars at Schuylkill Haven or Lackawaxen.

John Norbeck

director of PA State Parks 2010-2012

John Norbeck, director of PA State Parks 2010-2012, spoke to 44 people at the Community College of Philadelphia January 27, 2014. He had to resign his position because he opposed drilling for gas or oil in parks. If he hadn't the Corbett administration, which favored drilling, would have fired him.

Companies have offered to drill under parks horizontally from outside their boundaries, rather than verticMapually from within their boundaries, but Norbeck was unconvinced. Drilling spoils the viewshed, makes noise, fouls the air, and when gas is burnt lights up the night sky. Drilliing inside or just outside a park would wreck the serenity people go there to enjoy.

The 1955 state Natural Resources Act says state parks are to be preserved for future generations. To Norbeck that meant no drilling or timbering. These activities are legal in state forests.

He commended Jeff Schmidt, newly retired state director of the Sierra Club, for making his resignation a public issue. A public hearing in Philadelphia called people's attention to firing. Perhaps because of this publicity the Corbett administration has since announced it has no plans to drill in state parks.

But the issue is not dead. The state owns mineral rights under 80-85% of its 120 state parks, 61 of which lie atop Marcellus shale. The law says the owner of mineral rights must be given access to them. If the state doesn't buy the 15-20% of mineral rights now in private hands, our parks remain vulnerable.

Much of the gas the state doesn't own lies under parks acquired by Maurice Goddard, Secretary of the PA Department of Forests and Waters, 1954-78. In trying to put every Pennsylvanian within 25 miles of a state park, he stretched his capital by buying only surface rights.
