Performance Year	July 1, 2014	June 30, 2012
Baseline Year	July 1, 2015	June 30, 2007

If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the water use baseline was adopted:

Fiscal year 2007 was chosen because it was the first year BHSU measured its greenhouse gas emissions.
