Thank you very much, Mr. Chair.
Thank you for your presentations.
On one of the slides they mentioned gasoline supply and fuel quality regulations as factors affecting gasoline prices. I was wondering, with the environmental changes and everybody wanting to see us improve our environment, if we have cleaner fuels, is that going to increase costs? By how much will it increase refining costs? Have we changed our regulations in the last few years so that might have increased refining costs?
