Section B. In this section we discuss haze and its effects on visibility.

• Haze occurs when small particles in the air reduce visibility. There are two types of haze:

• Human-caused haze occurs when activities such as burning coal, oil, gas and wood in power plants, factories, vehicles or homes release particles into the air.

• Natural haze occurs when dust is blown into the air and when occasional forest fires release particles into the air.

• Scientists have extensively studied haze and have found that there is much more human-caused haze than natural haze.

• Scientists have also found that human-caused haze travels farther because the particles are usually smaller and lighter.

• The particles that form human-caused haze, particularly those from power plants with tall smokestacks, can travel hundreds of miles from their sources. Please see the diagram below:

Haze reduces visibility, making it harder to see distant objects such as hills, mountains, or other landscape features. On hazy days, distant objects fade, appear blurry, change color, or they disappear from view altogether.

In National Parks and Wilderness Areas visibility conditions are recorded by taking photographs on a regular schedule. The photographs below show the same view with different amounts of haze with the same weather conditions.

Less Haze

More Haze

3. Have you ever experienced haze reducing your ability to view a scenic vista? (CIRCLE ONE NUMBER)

1 Yes

2 No

Section C. In this section we discuss National Parks and Wilderness Areas.

In this survey, we will be discussing haze in National Parks and National Wilderness Areas. Some information on both of these types of areas is presented below:

• National Parks are public lands containing areas of special scenic, historical, or ecological importance.

• They are managed by the National Park Service, an agency of the U.S. Federal Government.

• These lands are managed to preserve the scenic, historical and ecological features, and to provide for the enjoyment of current and future generations.

• State and local parks are not National Parks.

4. How does the information above compare to what you previously thought of as National Parks? (CIRCLE ONE NUMBER)

1 Similar to what I thought

2 Different than what I thought

3 Was not aware of this information about National Parks

• National Wilderness Areas are public lands that are managed by the National Park Service and the U.S. Forest Service.

• These lands were set aside to be preserved in their natural state to provide habitat for wildlife.

• Only non-motorized recreation like backpacking, hunting, fishing, and horseback riding, as well as scientific research are allowed in National Wilderness Areas.

• State and local forests and parks are not National Wilderness Areas, neither are privately-owned forests.

5. How does the information above compare to what you previously thought of as National Wilderness Areas? (CIRCLE ONE NUMBER)

1 Similar to what I thought

2 Different than what I thought

3 Was not aware of this information about National Wilderness Areas

Please use the map that folds out on the last page of this booklet to help answer questions in the rest of this survey.

The region circled in red includes four National Parks, one National Monument, one National Historic Site and ten Wilderness Areas. This region does not include any large cities.

Section D. In this section we discuss Human-Caused Haze in National Parks and Wilderness Areas.

• Scientists have found that human-caused haze in National Parks and Wilderness Areas is largely due to particles that travel long distances to these areas.

• Human-caused haze in National Parks and Wilderness Areas is similar to what is often called smog in urban areas.

• Humidity does not cause haze but humidity increases the level of haze when there are particles present in the air.

7. On a scale of 1 to 5, where 1 is not concerned at all and 5 is very concerned, relative to other environmental problems, how concerned are you about human-caused haze in National Parks and Wilderness Areas? (CIRCLE ONE NUMBER)

NOT AT ALL CONCERNED	SLIGHTLY CONCERNED	SOMEWHAT CONCERNED	MODERATELY CONCERNED	VERY CONCERNED
1	2	3	4	5

There are four types of activities that result in human-caused haze in this region. These are shown in the chart below. Research by the U.S. Environmental Protection Agency indicates how much each activity contributes to the overall level of haze. This information is summarized in the chart below.

Where Does the Human-Caused Haze in the Regions Circled in Red Come From?

ACTIVITIES IN AND AROUND PARKS AND WILDERNESS AREAS 25%

HOUSEHOLD ACTIVITIES INCLUDING CARS AND TRUCKS: 45%

BUSINESS, INDUSTRIAL AND AGRICULTURAL: 25%

POWER PLANTS: 25%

8 . Is there anything about the sources of human caused haze above that you did not know before reading this survey? (CIRCLE ONE NUMBER)

1 Yes

2 No

Section E. In this section we discuss ways to reduce Human-Caused Haze and Improve Visibility Conditions in National Parks and Wilderness Areas.

• The U.S. Congress has passed laws calling for reductions in human-caused haze in National Parks and Wilderness Areas.

• The laws require states to work together in regional partnerships to reduce human caused haze in these areas.

• Regional agreements are needed because the particles that form human-caused haze can travel hundreds of miles from their source.

• Haze could be further reduced by:

• Installing improved technology at coal-fired power plants to reduce emissions.

• Controlling particles released during oil and natural gas production.

• Switching power plants and factories to cleaner fuels such as natural gas.

• Reformulating motor vehicle fuels.

• The states shown on your map are considering programs that would reduce haze in the region circled in red.

9. Do you think that changes in human activities could reduce haze in the National Parks and Wilderness Areas located in the region circled in red? (CIRCLE ONE NUMBER)

1 Yes

2 No

In the next section of the survey, you will be asked about these programs.

Please refer to the picture set that came with your survey booklet.

The photos show visibility conditions that currently occur at National Parks and Wilderness Areas in this region. The photos are from an area where visibility has been monitored on a regular schedule. They were taken at the same time of day during the same season on days without bad weather.

Photos of visibility conditions on each day were sorted from best to worst. The photos you see were chosen to represent five categories of visibility: A, B, C, D, and E.

• Photo A represents the best visibility category.

• Photo E represents the worst visibility category.

• Each category was selected to represent an equal number of days.

The photos represent the average visibility level for each category. For example, the worst visibility conditions on average would be like Photo E. Of course, some days in this category might be a little better and some might be worse.

The chart below shows the percent of the year and number of days in each category. Each bar represents 20% of the year, which is 73 days

10. Do you see differences in the levels of haze between photographs…

Photos A and B Yes  No  Photos D and E Yes  No 

Photos B and C Yes  No  Photos A and E Yes  No 

Photos C and D Yes  No  Photos B and D Yes  No 

Scientists have estimated the visibility conditions that would exist if there were no human-caused haze. Of course, even in the absence of haze there would still be some days when visibility is poor due to bad weather.

The chart below shows current visibility conditions in purple and visibility conditions that would exist without human-caused haze in orange.

For example, the chart shows that there are currently 73 days with visibility conditions like Photo A. This would increase to 365 days if there were no human-caused haze.

Bar charts like the ones you have been looking at can be used to describe the visibility improvements that can be achieved by reducing human-caused haze by different amounts.

As an example, the chart below shows current visibility conditions next to improved visibility conditions that would result from a specific program.

Different ways of setting up a program to reduce human-caused haze could result in different levels of visibility improvements. In this particular program, there would be more days in a typical year with higher levels of visibility like those in Photos A and B, and fewer days with lower levels of visibility like those in Photos C, D and E.

Section F. In this section we discuss other characteristics of programs to reduce Human-Caused Haze and ask for your opinion on some example programs.

All particles that form human-caused haze in National Parks and Wilderness Areas reduce visibility. Some of these particles can also impact the ecosystems in those areas.

• Particles that impact ecosystems can affect water quality, soil, plants, and in turn, the growth and variety of plants and animals.

• These effects occur very slowly, so most visitors to these areas would not notice changes in the growth and variety of plants and animals from one year to the next.

Some ways of setting up a program to reduce human-caused haze would result in a small reduction in harmful impacts on ecosystems while other ways would have no effect.

11. Before reading this survey had you heard anything about the impacts of human-caused haze on ecosystems in National Parks and Wilderness Areas? (CIRCLE ONE NUMBER)

1 Yes

2 No

Some of these particles can also impact some people’s health when they visit these areas.

• The level of haze at National Parks and National Wilderness Areas is less than the level that is usually present in urban areas.

• Few visitors to these areas experience health impacts from the current level of haze.

• Some visitors who have respiratory problems may experience coughing or shortness of breath on days with high levels of human-caused haze.

Some ways of setting up a program to reduce human-caused haze would result in a small reduction in health impacts to some visitors with respiratory problems while other ways would have no effect.

12. Before reading this survey had you heard anything about the impacts of human-caused haze on visitor health in National Parks and Wilderness Areas? (CIRCLE ONE NUMBER)

1 Yes

2 No

The amount of time required to reach the program goal will depend on how the program is set up. Any program will steadily reduce human-caused haze in the region circled in red by controlling more and more sources of particles over time.

For example, if the program takes 10 years, in 5 years the program would be one-half of the way to achieving its goal. Or, if the program takes 20 years, after 5 years the program would be one-quarter of the way to achieving its goal.

13. How important to you is the number of years it takes a program to reach its improvement goal? (CIRCLE ONE NUMBER)

NOT AT ALL IMPORTANT	UNIMPORTANT	NEITHER IMPORTANT OR UNIMPORTANT	IMPORTANT	VERY IMPORTANT
1	2	3	4	5

Reducing human-caused haze in this region would be accomplished by improving pollution control equipment and shifting to cleaner, more expensive sources of energy. The costs of most of these activities would ultimately be passed on to households through higher prices and taxes.

You would have to pay each year while any program is being implemented. You would also continue to pay each year after the final improvement goal is reached. This is because the new pollution control equipment will need to be operated each year and because the cleaner energy sources are more expensive.

14. Are you surprised that you would have to pay for a program every year? (CIRCLE ONE NUMBER)

1 Yes

2 No

Now we are going to ask you for your opinions on five programs to reduce human-caused haze only in the region circled in red on your map.

Each program to reduce human-caused haze will be described in terms of the following five characteristics:

• The improvement in visibility.

• Whether there is a small reduction in harmful ecosystem impacts.

• Whether there is a small reduction in the health impacts on some visitors with respiratory problems.

• How many years it would take for the program to reach its final improvement goal.

• The cost to your household every year.

The difference in the characteristics of the programs will depend on what types of particles are being controlled. Keep in mind that the programs are only designed to reduce haze in the red circled region. There are other ongoing programs to improve air quality in cities.

In each question we will ask you to decide whether you would vote for a specific improvement program. Please consider the description of the improvement program in each question carefully.

Before you begin, we’d like you to keep something in mind:

Surveys like this one, where people are asked to make choices about programs, are used to provide information to the government about what public policy issues people are concerned about and the tradeoffs they are prepared to make.

In some cases, people may vote “yes” for a program at a cost that they really would not pay. This is because when responding to the questions, some people may not think about the consequences of paying for the program in terms of their household budget, what they can afford, or other things they need or want to spend their money on.

Make sure you are aware of the cost to your household when making your choices in response to the questions in the next section.
