Air Pollution Project Problem: Last year, Chinese leader Xi Jinping and President Obama struck a deal to limit greenhouse gases, with China committing for the first time to cap carbon emissions and Obama announcing a target to cut U.S. emissions 26 to 28 percent below 2005 levels by 2025. (http://www.washingtonpost.com/business/economy/china-us-agree-to-limit-greenhouse-gases/2014/11/11/9c768504-69e6-11e4-9fb4-a622dae742a2_story.html). However, last January, the CT Mirror published an article suggesting that Connecticut’s summer air is some of the worst on the East Coast. As stated in the article, “EPA projects that this same area is unlikely to meet the proposed standards by 2025”. As a class, we will investigate potential strategies for meeting the proposed standards. Each team will choose a pollutant based on National Ambient Air Quality Standards. Teams will research health impacts and three different methods for reducing emissions of the pollutant must be considered, including capping and trading of emissions. Listed in the table below are Connecticut's 10 largest on- and off-site emitters of toxic chemicals. COMPANY NAME ADDRESS ANNUAL EMISSIONS (lb/yr) Allnex USA, Inc.

Step 1: Determine pollutant for which emissions will be reduced. • Characterize emissions • Determine potential pathways for pollutants • Draw an Exposure Pathway Diagram for chosen pollutant Step 2: Identify methods for reducing emissions Step 3: Determine most effective method for reducing pollutant • Make recommendation Deliverables: 1. As a group you will prepare a 5 page (minimum) report summarizing the results of your analysis. Use Time Romans font, 12-pitch, double spaced and 1 inch margins. Cite references properly in paper. Report due on Monday, Dec. 14. Submit the paper via BlackBoard through TurnItIn. 2. Each team will need to prepare a sheet summarizing a brief description of the strategies they are using, along with new terms and concepts they have learned from the exercise. On Tuesday, Dec. 8, you will need to submit an electronic version of your summary sheet to be posted on BlackBoard.
