Some questions for the day...
1. How is understanding the current world population and expected growth, the relationship between per capita energy use and HDI, and HDI and ecological footprint essential to understanding how humans use resources at unsustainable rates?
2. What are the nine sources of energy listed on the Lawrence Livermore National Laboratory? What are the three largest sources of energy? What are the two major uses of energy? How are the sources of energy split between the two major uses of energy? How much electricity does the US import (net)? What is the approximate % loss of energy throughout the system from start to finish?
3. What factors drive our current energy portfolio (ei why petroleum, natural gas, and coal)? Why highly concentrated energy particularly important ot the transportation sector? Does the US have large reserves of petroleum, natural gas, or coal? What is a reserve? How does US oil production stack up on the world scene? How does the number of producing oil wells stack up on the world scene? Is the US a major producer of coal and/or natural gas? How does current US production of oil relate to production in the past several decades? What is institutional inertia? How does institutional inertia determine (at least partially) our current energy portfolio?
4. What factors drive current interest and potential future increases in alternative energy? How does the current volatility, current high market price, and foreseeably high market price for petroleum increase interest in alternative fuel sources? How has the is the cost of production domestic petroleum production changed in recent years? How is the cost of production domestic petroleum production expected to change in the future? What does Prof. Low mean by "sourcing concerns" when talking about petroleum? Why is this an issue in determining our future energy mix? What are the major pollutants that are emitted during the combustion of fossil fuels? How are do the pollutants differ based on the fuel (petroleum, natural gas, coal) used? What new regulations have just been implemented that might have an effect on the nation's future energy portfolio? How does the push toward a more sustainable society drive current interest and potential future increases in alternative energy?
5. What is the utility of dividing electricity generation sources into baseload, peakers, uncontrollable and predictable and uncontrollable and unpredictable? How to biomass, coal, nuclear, hydroelectric, natural gas, tidal, geothermal, solar thermal, solar PV, and wind fit into these categories?
6. Why is there so little room for large improvements on the generation side of the energy equation?
7. Why is it difficult to compare the environmental, social, and human health consequences of different mechanisms of generating energy?
8. Why is it important to consider the end use of at the generation stage for certain situations? Why is it relatively rare that our systems actually do this. What are some of specific examples of particularly good generation-consumption fits?
9. What is a fuel cell, how does a fuel cell work, and why do you look foolish if you say or insinuate that fuel cells generate energy?
10. What is "the grid"? A shift from less sustainable, traditional baseload and peaker plants to more sustainable uncontrollable and unpredictable will require what changes in "the grid"?
11. What is general anthropomorphized attitude of the American electricity consumer? Why is it important to understand the requirements of electricity generation and distribution? What is a "smart grid"? What specific improvements to existing grid infrastructure will be required to meet the needs of a uncontrollable sustainable energy generation mixes? Which of these challenges will be easier (or harder) to accommodate in the near future?
12. When considering a holistic approach to energy, why is minimizing energy conversion important? How can energy infrastructure be redesigned to address the increasing use of electronic devices that run on direct current? What are examples of directly using mechanical energy to do work instead of using mechanical energy to generate electricity which can then be used to do work?
13. What is co-generation? What is an example of co-generation?
14. What are some examples of "low-hanging fruit" that could be used to reduce energy consumption? What are some examples of the "high-hanging fruit" that could be used to reduce our energy consumption?

Yellow Dirt Project Blog Summary
The Fundamentals from Yellow Dirt
-Written by Judy Pasternak
- Most of book takes place in 1940s during WWII and throughout Cold War
-Tells the story of government’s desperate push for more nuclear weapons
- Needed uranium extracted from mine on Navajo land
- Story of Navajo tribe that labored in mine and the subsequent health issues
- Vanadium Company of America (VCA)- mined for vanadium—element that was crucial to the construction of armor plates for warships
-Every 6 pounds of vanadium harvested from carnotite yielded one pound of harvested uranium
- At first uranium secretly sold to U.S. gov’t to support Manhattan Project
- Central focus of book tells the story of the betrayal of Navajo land and people by mining companies and U.S. gov’t
- Despite apparent health effects of uranium, the government still allowed the employment of Navajo people to work on mines
- Practices continued throughout Cold War until end of 20th century due to the demand for atomic bombs at this time
- Effects on Navajo people
- Thousands of Navajo miners worked in mines unprotected despite the warnings from physicians and scientists
- Uranium dust not only affected miners but entire Navajo community due to it contaminated air, soil and water—these findings were presented to government
- Radioactive “yellow dirt” found in Navajo drinking sources, walls and floors, playgrounds, homes and buildings, and garbage dumps. Navajo people still affected by the mining and many deaths can still be attributed to uranium mining in area.
Uranium
— Different grades of Uranium ore
-Very High-grade = 200,000 ppm Uranium (20% U)
- High – grade = 20,000 ppm Uranium (2% U)
- Low-grade = 1,000 ppm Uranium (0.1% U)
- 85 % of Uranium is hydrothermal
The Navajo Culture
- Diné- the name the Navajo call themselves. Means “The People”
- Dinétah = The Navajo Land
- Currently largest federally recognized tribe with 300,048 members
- Reservation is the largest Indian reservation in the United States
- Migrated from Canada, settled near Pueblo people
- Healing: Medicine men = Hatalii
- Believed that violation of taboos causes ailments
- Ceremonies usually last at least 4 days
Politics
- Radium discovered and mined with vanadium in 1910’s and 1920’s
- Used in Marie Curie’s experiments of fluorescence and patent medicines
- Vanadium used to strengthen ship hulls during and after WWI
- Peruvian mine slowing production for VCA by 1931—forced to move to Navajo reservation
- Uranium = a known waste product of Vanadium refining
- Domestic production 1938 of vanadium/uranium = 70,000 tons in 1948; by 1956 = 3,000,000 tons
- October 28, 1957- “We have arrived at the point where it is no longer in the interest of the federal government to expand the production of uranium concentrates”
Chemistry
- Nuclear reaction—change in the nucleus of an atom; emission of radiation
- 1896—discovery of radioactivity in Uranium salts by Henri Becquerel and Marie Curie
-Uranium that remains outside the body is much less harmful than uranium that is inhaled or swallowed
- Long-term intakes of uranium isotopes in food, water, or air can lead to internal irradiation and chemical toxicity, increased cancer risk, and liver damage
Radon
- Inhalation is the main means of entry of radon into our bodies
- Lung cancer and other pulmonary diseases are the main diseases from radon exposure
- Other forms of cancer also prevalent in uranium miners
- Birth defects in Navajo babies during uranium mining were 2 to 8 times higher than national average
Current Domestic Nuclear Situation
- U.S. is the world’s third largest producer of nuclear power
- 2010: U.S. had 104 reactors that produced 807 billion kWh (20% of electrical output)
- Four to six new nuclear reactors expected to be built by 2020
- No new constructed has occurred since 1977
- Since 1970s U.S. has dramatically improved safety and operational performance
- Net capacity is now 90% and safety standards exceed targets
- Exelon- largest U.S. operator—has plans to update most of reactor fleet to provide the equivalent of one new reactor by 2017
-September 2011—Nuclear Regulatory Commission extended 71 reactors w/ more applications for extensions expected in 2014
- The Energy Policy Act in 2005 provided much needed funding for nuclear power
- Tax credits and federal loan guarantees
- Incentivized 19 applications for 14 plants involving 21 reactors all over U.S.
- U.S. government has invested heavily in nuclear reactor research and development
- Particularly concerned with next generation reactor technology
- Domestic uranium production supplies about 10% of U.S. requirements for nuclear fuel
- As of 2008 U.S. uranium reserves provide a projected 23 years of uranium at current demand
- Wyoming and New Mexico lead the nation in total uranium reserves
- Together they hold roughly two-thirds of domestic uranium reserves

Lecture 33 Summary and Notes
Some questions for the day...
1. Real-time, interactive wind maps of the lower 48 (like the one here), while not as useful for siting windmills or win farms, are still pretty awesome.
2. When thinking about the future evolution of electricity generation and distribution, why is it important to consider where population density is the greatest. Why are considerations of the evolution of where Americans live particularly important for the potential future of solar energy?
3.How does electricity consumption vary throughout the day? How does this variation change seasonally? Why is this relevant to discussions of electricity generation from solar energy?
4. How does an industrial-scale solar thermal electricity generation plant work? What are the two basic designs? How does residential (or commercial or small-scale industrial) solar thermal work? How is it different from industrial-scale solar thermal? What are the specific advantages and disadvantages of solar thermal?
5. How does solar PV work (ei how do solar PV panels produce electricity)? What are the four basic categories of solar PV cells? Which are currently the most efficient? Which are currently the most commonly used? Why is there a difference? What % of campus energy is supplied by our new solar PV installations on the parking deck and the Law School? Is the W&L parking garage a net producer or consumer of electricity? Where are the best places in the lower 48 to site solar resources? What are the specific advantages and disadvantages of solar thermal?
6. What are the factors that will determine whether a state will be a net importer or exporter of electricity? What is "the grid"?
Slides from lecture today are on Sakai. Your reading assignment for Wednesday's class is here.

Lecture 31 Summary and Notes
From the Plundered Planet Book Group...
Plundered Planet Paul Collier
General message:
How to use natural assets: nature + technology + regulation = prosperity
- Without regulation, you get plunder
- Without technology, you get hunger
The book sets out to try to solve the dilemmas that arise from natural assets in low-income countries. He writes that economics and environmental studies need each other and can be compatible.
Part I: Resource curse
Studies have found that countries with higher amounts of natural resources have slower economic growth than countries that do not; similarly, the absence of resources in democratic societies increased economic growth, and democratic countries with an abundance of resources have more economic troubles. So, are resources a curse?
It seems that resources are a curse in countries that have deeper issues. Remember the difference between Sierra Leone and Botswana and Nigeria and Norway.
countries with a comparative advantage should specialize it should use it to trade with other countries; some countries specialize in resource extraction which hinders other developments
Basically, weak or corrupt governance and non-agricultural resources make the asset of natural resources into a curse because there is no proper regulation of the extraction and distribution of natural resources.
Part II: Discovering natural assets
Natural assets lack owners so they can be plundered more easily. Collier divides the world into four quadrants: OECD: Russia/China/satellite nations; Emerging economies; Countries of the bottom billion
What is surprising about the poorer countries is that they tend to be resource-rich countries at present. This isn’t because the land has a greater amount of natural resources (because Africa was not naturally endowed with as many subsoil resources). The difference is that richer countries have been extracting resources for a longer period of time.
Collier highlights that for the bottom billion it is important to think of assets are an opportunity
Problems with natural assets in these countries:
- Tend to be located disproportionately in “difficult” territories
- Only ¼ of natural assets have been discovered in the botton bill compared to rich countries which means something mustve gone wrong
- Discovering what’s underground = EXPENSIVE
Collier’s solution: think of searching for assets as a public good
- Best to allow one entity to make search, let foreign enterprise perform the search b/c it’s so expensive (or even donors like the World Bank or the IMF and these donors could help multiple countries but it’s hard to get them to do this b/c they want to do more “picturesque” jobs like schools)
- Make geological info available as a public good
- Info clarifies what the resources/geological territories are worth so the gov can know how to sell these plots of land
Part III: Capturing Natural Assets
The problems that arise in the phase of capturing natural assets are corruption and underdevelopment.
- Corruption: extraction/discovery relies on extraction companies and the government to get revenues from resources to the country/its people
- Underdevelopment: revenue isn’t used domestically so the country can’t be improved and there is no increase in money in their market
Collier’s solutions:
- Transparency is needed when discovering resources (publish what you pay/EITI)
- Auction off rights to the resources (4 companies competing, will get true value of the resources, eliminates asymmetric info problem)
Extra hindrance:
- Taxes create problems: inefficiency in government and economy; creates uncertainty for companies who want to extract resources; companies try to dodge funky taxes which hurts the country’s revenue
o Contingencies: try to solve inefficiency; agree on a system of taxes ahead of time
o Royalties: reduces asymmetric info; tax on revenue
Overall solution Government should use tax structure w/ contingencies; transparency of companies and government; use royalties b/c they are observable (should be in tax code); legally-binding tax code
Part IV: Selling the Family Silver
Problem: How do we make sure the revenues are being used within the country (benefit future and present generations)
- Governments must balance consumption and savings
- Try to sustain economy with sustainable infrastructure rather than depleting resources
Solution: yield rate of return while the asset is still in the ground
- At what rate should we spend, save, invest (domestically and abroad)
o Norway invest 100% into capital markets and consume less at the beginning of extraction of natural resources
o Ghana spent too early and too much once they discovered early
o Boom and bust cycles: use savings in bust cycles; save a lot during boom cycles
o Long-term infrastructure deals are good but they should be made public for rights to resource extraction
Part V: Investing in Investing
- Most difficult part, but also must important
- Invest in public goods
o Get rid of corruption/ improve management of investment
o Need to promote big-scale projects
- Encourage private investment
o Lessens risk on government
o Mobility in market
- Lower price of capital goods
o Suggests trying to reach trade agreements with other countries or partnering with neighboring countries
- Use examples like Botswana and Malaysia rather than Norway
Slides are on Sakai. For Friday, please read A Measured Rebuttal to China Over Solar Panels by Keith Bradsher and Matther Wald published in the March 20, 2012 edition of the New York Times.

Lecture 30 Summary and Notes
Some questions for the day...
1. What are the two different types of diamond deposits? How do they differ from the viewpoint of a prospector? How does the morphology of the mine differ based on type of deposit? Which type of deposit depends on the high density of diamonds relative to most other common crustal materials?
2. What is the evidence that there has been a kimberlite eruption in Rockbridge County? How can you be certain that this kimberlite is not diamondiferous?
3. What is unique/special about the formation processes, physical properties, and societal valuation of diamonds out of all of the gems, and other MSI that we have and will discuss in this class?
4. How has the advertising of diamonds evolved since the origin of the "A Diamond is forever" campaign in the late 1940s. How is the marketing/advertising of diamonds an example of a manufactured desire? How does the role of a diamond in the US engagement ritual factor in this manufactured desire? What was the average retail price for a diamond engagement ring in 2011? What is the "standard" equation used in the the calculation of how much should be spent on a diamond engagement ring? Who created this standard and why was the standard created in the first place? According to www.engagementringcalculator.com, will a proposal in which one (or more) parties is pregnant require a more or less expensive ring?
5. What are the 4 Cs? How do two of the Cs describe the composition of the diamond at different scales? How has the inflation-adjusted, wholesale price per carat changed over the past 50 years? What is the current wholesale price for a 1.00 carat, colorless (D), internally flawless, brilliant (round) cut diamond? What about the retail price for the same diamond?
6. What is the Kimberley Process Certification Scheme? What was the reason that Global Witness cited for leaving the Kimberly Process in late 2011?
7. What are conflict diamonds? Why are conflict diamonds an American problem? According to the WDC, what percent of blood diamonds currently come from conflict zones? According to the UN, what percent of blood diamonds currently come from conflict zones? Why is there such a wide gulf in between these two estimates? What were the respective roles of Sierra Leone and Liberia in the diamonds that helped to fund the WTC attacks on 9/11? Why are the DRC and Zimbabwe considered two potential sources for conflict/illegally traded diamonds? What are some of the things that you should look for when trying to source (or avoid sourcing) smuggled diamonds?
8. Is the statement by World Diamond Counsel chairman Eli Izhakoff that the industry knew nothing of the conflict-diamond trade until 1999-2000 indicative of willful deceit or stunning incompetence?

Slides are on Sakai. Please read Colin Tudge's review of The Plundered Planet, By Paul Collier in the Friday 09 July 2010 edition of the Independent for Wednesday's lecture presentation by the Plundered Planet Book Group.
1. What are the two different types of diamond deposits? How do they differ from the viewpoint of a prospector? How does the morphology of the mine differ based on type of deposit? Which type of deposit depends on the high density of diamonds relative to most other common crustal materials?
2. What is the evidence that there has been a kimberlite eruption in Rockbridge County? How can you be certain that this kimberlite is not diamondiferous?
3. What is unique/special about the formation processes, physical properties, and societal valuation of diamonds out of all of the gems, and other MSI that we have and will discuss in this class?
4. How has the advertising of diamonds evolved since the origin of the "A Diamond is forever" campaign in the late 1940s. How is the marketing/advertising of diamonds an example of a manufactured desire? How does the role of a diamond in the US engagement ritual factor in this manufactured desire? What was the average retail price for a diamond engagement ring in 2011? What is the "standard" equation used in the the calculation of how much should be spent on a diamond engagement ring? Who created this standard and why was the standard created in the first place? According to www.engagementringcalculator.com, will a proposal in which one (or more) parties is pregnant require a more or less expensive ring?
5. What are the 4 Cs? How do two of the Cs describe the composition of the diamond at different scales? How has the inflation-adjusted, wholesale price per carat changed over the past 50 years? What is the current wholesale price for a 1.00 carat, colorless (D), internally flawless, brilliant (round) cut diamond? What about the retail price for the same diamond?
6. What is the Kimberley Process Certification Scheme? What was the reason that Global Witness cited for leaving the Kimberly Process in late 2011?
7. What are conflict diamonds? Why are conflict diamonds an American problem? According to the WDC, what percent of blood diamonds currently come from conflict zones? According to the UN, what percent of blood diamonds currently come from conflict zones? Why is there such a wide gulf in between these two estimates? What were the respective roles of Sierra Leone and Liberia in the diamonds that helped to fund the WTC attacks on 9/11? Why are the DRC and Zimbabwe considered two potential sources for conflict/illegally traded diamonds? What are some of the things that you should look for when trying to source (or avoid sourcing) smuggled diamonds?

Some questions for the day...
1. How do diamonds form? Specifically, what combination of events are required for diamonds to exist at Earth's surface?
2. What are the differences between the carbon polymorphs (graphite and diamond) in terms of physical properties such as density and hardness, type of chemical bonds present, coordination polyhedra for carbon?
3. What is the stability region of diamond in PT space/ Why does diamond turn into graphite during normal upwards mantle convection? Why is the mantle beneath ancient cratons suc a good place to form so many of the diamond that evetually make their way to the surface of the Earth? What is a kimberlite pipe? How is a kimberlite eruption different from a "normal" volcanic eruption?

Lecture 27 Summary and Notes
We began our lecture today with some excerpts from Marc Reisners Cadillac Desert. I hope that this gave you some appreciation of:
a. the vast effect of dams on the American landscape (particularly in the American West)
b. the importance of US hydroelectric power generation not only in our modern energy portfolio but also in the development American and even world history
c. some of the working conditions that were endured during the construction of some of the major public works project that still provide us with some of our energy needs decades later
Some questions for the day...
1. What is the great American dam? What is the largest American dam? What external forces helped to allow for the construction of the Hoover Dam in only three years? What external forces allowed the projected surplus power generation from the Grand Coulee Dam to be consumed decades before predicted? When did dam construction in the USA peak? What was going on at the Hanford Reservation that required so much power? What is the one thing that humans can do to a river that nature cannot undo? What river is "like a forty-pound wolverine that can drive a bear off its dinner"?
2. Do hydroelectric dams function as base load or peaker plants? What are the relative capital and operating costs of a hydroelectric facility vs. a coal or natural gas plant? Is there room for expansion for hydroelectric facilities in the USA? What about the world? What is the average life of a North American dam (according to the American Society of Civil Engineers)? How does this "lifespan" bode for existing US hydroelectric infrastructure? How are dams responsible for the flux of anthropogenic greenhouse gasses into the atmosphere?
3. How does the EROEI of a dam (or any power plant, for that matter) change as a function of time?
4. What is river-basin "accounting"? Who "pays the bills" in river-basin "accounting"? What use(s) get(s) subsidized in river-basin "accounting"? Why is river-basin "accounting" important in the construction of large hydroelectric projects like those in the American West?
5. What is a pump storage plant (PSP)? How does a PSP work? How is a PSP different from a "normal" hydroelectric dam?
Slides shown in lecture today are on Sakai. Excerpts from Cadillac Desert are also on Sakai (Cadillac Desert.pdf). Your reading assignment for Wednesday is the first three sections of How the African Diamond Trade Works by Alia Hoyt

Lecture 25 Summary and Notes
Some questions for the day...
1. What pollutants (general categories)will the new mercury standards (MATS) for US power plants regulate? Why is this new regulation significant? How many power plants are expected to retire as a result of the new regulations? What are the expected effects of the MATS on the consumer price of electricity? What are the benefits that are predicted by the EPA?
2. Coal, NG, oil, and biomass can all be used to generate steam to make electricity. What are the differences between these different combustion sources in terms of "peaking" ability, CO2 flux per unit electricity generated, potential pollutants, US reserve volume, and price?
3. What is a biogeochemical cycle? What is the carbon cycle? What are the major reservoirs of carbon in the carbon cycle? What are some of the mechanisms through which carbon move from reservoir to reservoir? How does the combustion of fossil fuels affect (disturb) the carbon cycle? Where does the carbon that used to be in fossil fuels end up after combustion? Why is more carbon in the ocean a problem? Why is more carbon in the atmosphere a problem?
4. Why is the regulation of CO2 pollution so difficult? How is our classical thinking about defining 'acceptable' risk largely inadequate for dealing with CO2 pollution? How would the predefined probability approach be applied for CO2 pollution? How would the 'currently tolerated approach to defining 'acceptable' risk be applied to CO2 pollution? How would economic approaches like cost-benefit and cost-utility analysis- particularly in a multi-risk assessment be applied for CO2 pollution? In such a scenario, who bears the cost of pollution reduction? Who benefits from risk reduction related to pollution reduction?

Lecture 23 Summary and Notes
Some questions for the day...
1. How to the predefined probability approach, the currently tolerated approach, and the economic approach (cost-benefit analysis and cost-utility analysis) differ as mechanisms for determining acceptable risk? What is a historic example of a cost-benefit analysis that demonstrated the economic savings of risk reduction outweighing the cost of intervention? How does cost-benefit analysis work when more than one risk or potential risk is present? In a cost-benefit analysis, who generally pays for the costs associated with failure to reduce a risk; in the same system, who generally benefits from the failure to reduce a risk? What is VSL? How does VSL figure in to calculating risk of some behavior? What is a modern estimate for VSL (American, not too old)? According to the WHO, when is a risk acceptable?
2. What is a life cycle analysis? What is full cost accounting? What are externalities and and how does their exclusion from economic transactions distort the decision-making processes?
3. What is average price of coal as an energy source (cents per kilowatt hour? How does this price compare with electricity that has been generated from other sources? How would full cost accounting (adding in all of the “externalities” ei costs are external to the coal industry) affect the price of electricity produced from coal coal combustion?
4. What are the most common coal combustion products (both gasses and solids)?
5. How common are acute coal mining related deaths in the USA (over the past 30 years)? How has this changed from 100 years ago? What combination of factors have been responsible for these changes? 6. How do acute mining deaths in the US compare with those over the past decade or so in China?
Slides from today's lecture are on Sakai and the data file for HW 8 is on Sakai and there are additional copies of the assignment tacked to my bulletin board if you missed class today. We will continue with coal on Monday with a further look into the waste stream of coal, a discussion of how electricity is generated from coal, how pollution control technology works, how recently adopted regulations by the EPA are affecting the viability of coal-fired power plants in the USA, and how burning fossil fuels such as coal affects the global carbon cycle. For Monday, please read Utilities announce closure of 10 aging power plants in Midwest, East by Juliet Eilperin published in the February 29 edition of the Washington Post and Christian environmental group says the EPA's new rules on mercury pollution is a pro-life issue by Jim Harger in the December 03, 2011 edition of the The Grand Rapids Press.

Lecture 22 Summary and Notes
Some questions for the day:
1. How do valley fills affect the runoff ratio in a watershed? How are flood peaks different in watersheds with more valley fill area? How does the physiography and the resulting way the West Virginians inhabit the landscape amplify flooding hazards?
2. What are the characteristics of mineable (either underground of surface) coal reserves? What are the techniques that are important in coal prospecting? Why are their so few coal geologists right now?
3. How is coal mined? What must be considered when mining an underground coal seam?
4. How and where is coal processed? Why does coal need to be proceeded (why can't it just be shipped directly from the mine to the power plant? How is coal separated from silicate material? What happens to the silicate waste material? Why is the disposal of silicate mine waste a problem in Appalachia?
5. How is environmental risk assessed? What factors need to be considered?
6. How do "we" decide the level of acceptable risk? What is the "standard" for acceptable risk using a predefined probability approach to risk definition? Who (and WHO) uses the 1 in 1 million standard? What does "1 in 1 million" mean? How do the current regulatory limits for Arsenic (As) in drinking water (USEPA or WHO) fit with the general risk goals of the regulatory community? Given the answer to the last question, is it safe to say that practical (ei economic) considerations also go into establishing current regulatory limits? What does the initiallism MCL stand for?
Slides from today are up on Sakai. Friday, we will look further into risk assessment and mitigation and recent efforts to address the waste stream of coal mining and combustion. There is no new reading assignment for Friday.

How do the current regulatory limits for Arsenic (As) in drinking water (USEPA or WHO) fit with the general risk goals of the regulatory community? Given the answer to the last question, is it safe to say that practical (ei economic) considerations also go into establishing current regulatory limits? What does the initiallism MCL stand for?
Slides from today are up on Sakai. Friday, we will look further into risk assessment and mitigation and recent efforts to address the waste stream of coal mining and combustion. There is no new reading assignment for Friday.

Lecture 21 Summary and Notes
Some questions for the day...
1. How does coal rank vary from North to South in West Virginia. How does the geospatial variation in coal rank in WV demonstrate the expected progression of coal composition with increasing P and T?
2. What is science? What is the scientific method? What is the difference between peer-reviewed scientific literature and mainstream literature? What are the essential components of a scientific paper?
3. What are the top coal producing states in the USA? What is the general geographic distribution of states whose production is dominated by surface mining vs. states whose production is dominated by underground mining?
4. How has the productivity (measured in the mass of coal that an employee can produce in an hour) of coal mining changed over the past 50 years? How does productivity vary east vs. west of the Mississippi? How does productivity vary surface vs. underground? How would you describe the area (east vs west) and mining method (surface vs underground) that is most productive?
5. Increases in productivity means less employees are required... What % of West Virginians are currently employed by coal mining companies? How has this changed in the past 30 years
6. What is a watershed? At what level of anthropogenic disturbance will stream biodiversity and water quality suffer? Below valley fills in the central Appalachians, streams are characterized by geochemical characteristics? What is conductivity? How is conductivity used to estimate water quality? What is the effect of increasing conductivity (and increasing dissolved material) on stream biodiversity?
7. What are the effects of MTR/VF mining on the hydrologic characteristics of watershed? What are nested watersheds? How do flood crests differ in nested watersheds? How to flood crests differ in watersheds with large amounts of urbanization or changes in surface characteristics due to MTR/VF?

Lecture 17 Summary and Notes
Some questions from today's lecture...
1. What important announcements regarding the KXL pipeline were contained in their recent earnings report (released on Tuesday, February 14th)?
2. What were the findings of the 2008 CARA report from the USGS? How was the appraisal conducted? What are the differences between discovered and undiscovered resources? Are these resources of reserves? Where are the big oil discoveries (or undiscoveries?) expected?
3. How have the findings of reports like the CARA affected Greenland?
4. Offshore petroleum exploration and drilling is more expensive than inshore but it expected to be a major (and growing) component of US and world petroleum production in the near future. What are the geologic limitations of off shore drilling (ei why can't you drill in the middle of the ocean and expect to get oil or natural gas)?
5. How have the laws regarding "who owns the sea" changed historically in response to humanity's ability to (and desire to) exploit off shore petroleum reserves?
6. What two environmental disasters in 1969 helped the reorganization and expansion of what would become the Clean Water Act and turned many Americans against off shore oil production? What role did the rate of domestic production in the late 1960s/early 1970s play in this anti-offshore sentiment? What are the current restrictions on offshore exploration and productions in the USA? How are these restrictions expected to change in the near future?
Slides from lecture today are on Sakai. I will begin grading your exams soon and send out an email when they ready. For break, remember to 1. read your book group book and 2. do your Feb Break homework assignment. Have a great break.

How many jobs will construction of the pipeline create (direct, indirect, temporary, and permanent)? How has the proposed pipeline been portrayed in the media? Are Americans generally for or against construction of the pipeline? What is the general location of the proposed pipeline? Are there other pipelines in this area? Is this the first Canada-US trans border pipeline? What is the Oglalla aquifer? Why are groundwater resources particularly valuable in the area atop the Oglalla aquifer? How common are "major" pipeline incidents? What are the historic trends in pipeline construction in the USA? How common are fatal accidents for truck carrying petroleum products? What are the advantages and disadvantages of pipelines? Why is it difficult to compare the relative dangers of pipelines and trucks? What is the likelihood of KXL oil being exported to non-US markets? What does fungible mean? Do individual consumers have the ability to choose where their petroleum products come from? How would the KXL pipeline affect this? Where is Canada? How did investors in TransCanada react to the Jan 18th decision by Obama to "reject" the KXL pipeline? What is the future of the KXL pipeline?
