# January 20, 2016 Gina McCarthy Administrator, USEPA USEPA Headquarters William Jefferson Clinton Building 1200 Pennsylvania Avenue, N.W. Mail Code: 1101 A Washington, DC 20460 Dear Ms. McCarthy: When we last communicated in November, we took the opportunity to clarify the situation with our Boundary Dam carbon capture and storage project. At the time, we were addressing technical and mechanical issues that we encountered in our first year of commercial operation. 1 can now assure you that we've addressed those issues and performance at the facility has improved considerably since. In fact, we captured more carbon dioxide in November 2015, just over 60,000 metric tonnes, than any month since the process was launched in October 2014, and we beat that total again in December 2015, capturing more than 61,000 tonnes. We also recently completed nameplate testing, where we successfully tested the capture limits of our facility, capturing 3,240 tonnes per day for three consecutive days representing 90% of CO2 emissions. So far, we've captured 540,000 tonnes of carbon dioxide since October 2014. We continue to identify and address mechanical and operational issues on this first-of-its-kind process, and we're confident we have the expertise and experience to keep on track with our goals. We are now operating the facility in a way that meets Canadian federal emission regulations, and satisfies the volume needs of our carbon dioxide buyer, which involves capturing approximately 2,700 tonnes per day. The design and demonstrated maximum capacity of the process can reduce carbon dioxide by 90%, or one million tonnes a year. We will operate at various levels to be mindful of costs and long-term system performance. We plan on capturing 800,000 tonnes of carbon dioxide in 2016. We have received much interest at home and abroad about the performance of the facility. We have begun publicly posting performance updates on our website at saskpower.com . We plan on continuing these updates throughout the year.

Page 2 January 20, 2016 Thank you for your continued interest and support of SaskPower's carbon capture and storage initiatives. Saskatchewan has demonstrated a commitment to the environment and to its residents by investing and innovating in this technology. This investment has the potential to benefit not just Canada but numerous countries that will continue to burn coal as a source of power for the foreseeable future. It would be an honour to host you for a visit to the facility in Estevan, Saskatchewan, Canada if you would ever like to witness the project first-hand. Sincerely,
M.J. (Mike) Marsh President and Chief Executive Officer, SaskPower
