This is a construction schedule document for SYNAR AML (Abandoned Mine Land) reclamation work under solicitation 140S0326B0002, issued by the Department of the Interior Office of Surface Mining Reclamation and Enforcement. The schedule outlines a 15-day project timeline for site preparation and environmental remediation activities associated with project code CC-023-005.

The construction activities are sequenced across the 15-day period and include mobilization, site clearing and grubbing, installation of an air incinerator, earth fill placement, fence construction (5-wire), traffic-bound surface course application, erosion control measures (straw wattle and rock check dams), and rip rap type IA installation at 12-inch depth. The schedule also incorporates soil stabilization and agricultural reclamation components, including gradient terraces, deep disking, and application of agricultural amendments (lime, nitrogen, phosphorus, and potassium), concluding with seeding operations. This schedule represents the typical sequencing and phasing required for a comprehensive mine reclamation project combining both engineering controls and environmental restoration activities.
