Expected volume of recycling

This seems to be a new challenge by reviewers, as there is no known formula or standard practice to calculate 'expected volume of recyclables'. Howard Williams' approach below is basically part of a Solid Waste Assessment that could be done for any facility type. Looking through resources, such as those found at the California Integrated Waste Management Board's posting, may be your best bet to identify a method that will offer this volume information (see case studies and approaches in Establishing A Waste Reduction Program at Work participant's manual at http://www.calrecycle.ca.gov/Publications/default.asp?pubid=776 ).

We're getting these comments also, and I admit to a little frustration about the relevancy of this metric. We are all guessing and spending time on a methodology for a requirement that doesn't require compliance with any metric. In my experience with other credits, it is the USGB's job to set the methodology and the standard. What is the point of this comment? Has anyone had a denial of the "metric" they provided subsequent to getting this comment?
