Solid Waste Cost Estimates

Owners or operators of solid waste facilities requiring closing and/or long-term care financial assurance shall annually adjust their facility closure cost estimates for inflation and submit updated information to the department. Most permitees must follow Rule 62‑701.630(4), Florida Administrative Code (F.A.C.). See Special Notes below for Used Oil and Waste Tire facilities.

Rule 62-701.630(4), F.A.C., estimate submission requirements

  • Form 62-701.900(28) - Closure Cost Estimating Form for Solid Waste Facilities
    • See guidance document on form page. Contact your permitting office for additional assistance.
  • Annual cost estimate adjustments may be made either by recalculating the maximum cost of closure in current dollars or by using the current year inflation factor.
  • For owners or operators using a Landfill Management Escrow Account to demonstrate financial assurance, cost estimates must be submitted between July 1 and September 1 of each year.
  • For owners or operators using an alternate financial mechanism to demonstrate financial assurance, cost estimates must be submitted between January 1 and March 1 of each year.

Calculation of the Inflation Factor

  • The annual inflation factor is derived from the most recent Implicit Price Deflator for Gross National Product published by the U.S. Department of Commerce in its Survey of Current Business, pursuant to Rule 62-701.630(4)(a)(2), F.A.C.
  • To calculate the current inflation factor, divide the latest published annual Deflator by the Deflator for the previous year.
  • Implicit Price Deflator data is published by the U.S. Department of Commerce, Bureau of Economic Analysis on its website,
  • The data necessary to calculate the inflation factor is released by the U.S. Department of Commerce at the end of March. Therefore, it is appropriate to use the previous year's factor when inflation adjusting cost estimates due between January 1 and March 1.
  • We recommend (and allow) the use of the inflation factor we calculate when annual deflators are first published for a 'new year' on or about April 1. As deflators, including previous year’s deflators, are revised several times a year, the inflation factor we publish in April is occasionally slightly different from what would be calculated later. (We now round up only when the fourth decimal is 9.)
  • The annual deflators used to calculate the latest inflation factor are dated March 26, 2020, and are 112.257 (for 2019) and 110.320 (for 2018).
