Data file is regenerated nightly and includes the latest month for which all data has been ingested. Trash data from Waste Management must be manually entered and is usually the limiting factor in publishing.
Staff may adjust records affecting previously-published months if opportunities emerge to improve the precision of those values. In the event of changing results, the latest / current values should take precedence over older versions of this spreadsheet.
