1. Community Impacts of Mariner East Pipelines Prepared for West Cornwall Public Meeting November 21, 2014 Presented by Sam Koplinka-Loehr, Clean Air Council

2. Presentation Overview Introduction Mariner East 1 & 2 Pumping Station Specifics Air Pollutants and Public Health Photo Source: Bob Donnan: http://www.donnan.com/EPA_Air-Quality_92711.htm

3. Clean Air Council Marcellus Shale Program Track current rulemaking and write comments on regulations Work with residents to comment and testify on natural gas infrastructure Lawsuits against polluters or agencies Community actions to achieve goals outside of regulatory pathways

4. 64% of PA is above Marcellus Shale. In 2013, PA had over 6,000 wells with 3 trillion cubic feet of gas production. These gas products have flooded regional markets and companies are trying to build pipelines to sell overseas.

5. Mariner East 1

6. New Pipeline 50 miles Western PA Existing Pipeline 300 miles Over 80 years old Oldest pipelines 4% Mariner East 1 Basics Source: 4% of US gas transmission pipelines were built before 1940 Canary LLC CEO Dan Eberhart http://canaryusa.com/aging-us-pipelines/http://canaryusa.com/aging-us-pipelines/

7. Switch the pipeline direction to pump natural gas liquids from wells near Houston, PA to the Marcus Hook Refinery near Philadelphia Increase pressure from 800 pounds per square inch (PSI) to 1400 PSI 18 new pumping stations and 17 new valve control stations 70,000 barrels per day Sunoco Logistics’ Plan

8. Natural Gas Liquids - Ethane Mariner East will transport 100% ethane as of 2015 Extracted as gas, but under pressure becomes a liquid Used industrially for plastics, anti-freeze, and detergents Extremely flammable

9. Sunoco Logistics is currently before the PUC requesting exemption from local zoning laws for pumping station buildings Current PUC process will determine whether or not pumping stations are “reasonably necessary for the convenience and welfare of the public” as well as whether Sunoco Logistics is a public utility Public Utility Commission (PUC)

12. Mariner East 2

13. Just the Beginning

14. Details Sunoco Logistics Claims: Mariner East 1 will be operational by Fall 2014 with 70,000 barrels per day of ethane and propane Mariner East 2 will be operational by 2016 with 275,000 barrels per day of natural gas liquids

15. West Cornwall Pumping Station

17. Previous Spill History

19. Emission Sources at Pumping Stations Electric Pump Motors Flaring of gas during maintenance operations and constant flaring of fugitive emissions Source: Data and images from State-only operating permit filed with DEP

20. Flare Design

21. Maximum expected annual flaring: – 312,800 standard cubic feet – Equivalent to 8,696 gallons – 23 gallons daily Could be more if there are maintenance issues Flare Volume

22. Flare will operate 24/7, igniting fugitive emissions from the motor and pipeline seals Flare Frequency

23. Equal to 5 constantly idling school buses Fugitive Emissions: Volatile Organic Compounds (VOCs)

24. 35.8 tons of carbon annually, equal to: – Annual carbon sequestration from 26 acres of forest – Burning 34,884 pounds of coal Carbon Emissions

25. Taking Action to Protect our Communities

26. Zoning Appeal DEP Hearing – 500 requests – Follow-up with Tom Hanlon thanlon@pa.gov Zoning and Air Permit
