Airspace Reduction from Thick Daily and Intermediate Covers

$1M-$10M (lost multi-year gas purchase contracts, asset valuation impairment, early investment in alternative gas sources) • $1M-$3M (contract renegotiation costs, early closure planning, new facility procurement, regulatory planning disruption) • $1M-$5M (accelerated closure costs, final cover system redesign, extended post-closure monitoring, early site reclamation costs, municipal contract premiums)

Capacity spreadsheets updated quarterly based on historical averages; contingency planning for early closure; manual negotiations with disposal contractors • Engineers, leachate specialists, methane technicians and lab staff informally track cover thickness and airspace loss with ad hoc survey notes, occasional drone/topo surveys, spreadsheets, and back-of-the-envelope density/volume calculations instead of a unified system that ties cover practices to leachate, gas, and cell performance. • Excel spreadsheets tracking cover depth by cell; email-based cover material requisitions; manual visual inspections ('skunk test' per site standards); paper logs of soil volumes placed; WhatsApp/phone coordination between operations and closure teams
