Q348. What if two methods are used to estimate waste disposal quantities in a single year? How does a reporter indicate that in e-GGRT?

A348. Within the HH module, the reporter may overlap years in reporting the methodologies used and the years in which they were used. For example, a reporter may say that they used scales to determine their waste disposal quantities from 2000 to 2009 and they used tipping receipts and other company records to estimate their waste disposal quantities from 1995 to 2003. If the years in which methods were used overlap, the reporter should use the text box in Subpart A asking the reporter for an "Explanation of any calculation methodology changes during the reporting year" to explain the different methodologies used and when they were used to estimate their waste disposal quantities.
