Attachment D.3 Example Activity Scenario Activity II: Post Natural Disaster Hazardous Materials and Debris Cleanup and Removal

California wildfires have damaged and/or destroyed Forest Service owned structures and special use permitted privately-owned structures located on National Forest System (NFS) lands. Removal and disposal of the structure related hazardous waste and debris generated because of the wildfires shall be conducted in two phases following the process being implemented by the California Environmental Protection Agency (Cal-EPA). The two phases are:

· Phase 1: Assessment, Removal and Disposal of Hazardous Waste/Asbestos and Removal and Disposal of Readily Accessible Debris

· Phase 2: Removal and Disposal of Debris, Ash, and Contaminated Soil

For the scenarios provided below, prepare, and submit a work plan that provides a description of how contractor would address each scenario. The work plan for each scenario needs to include and address the following:

· Description of the work to be performed.

· Discussion of any specific exclusions/assumptions the contractor may have regarding their response to the scenario in question.

· Anticipated contractor response time.

· Conceptual listing of personnel, including subcontractor(s) that would be utilized for the response.

· Conceptual listing of equipment and supplies to be utilized for the response.

· Safety & Health Plan and procedures the contractor will follow.

· Emergency Response Plan

· Container sampling and waste identification protocols that would be utilized.

· Hazardous material/waste management plan and protocols for material/waste handling, transport and disposal.

· Provide the estimated cost for the response. Breaking down cost items into key categories (work plan development, mobilization, performance of work, disposal cost, and final report preparation).

Scenario A The September 2020 Quartz Fire burned all or a part of 12 permitted recreation residences within proximity to each other in Big Santa Anita Canyon. Each recreation residence consisted of a cabin, storage shed and outhouse. The fire burned all three structures; a combination of two structures or one structure.

The burned or partially burned recreation residences are located above Santa Anita River which flows into Santa Anita Reservoir. The location (some on high steep slopes and others at the water’s edge) of the recreation residences combined with the first significant rainfall event will transport hazardous materials contamination into the river and subsequently into the Santa Anita Reservoir which is a source of drinking water for several highly populated downstream urban areas.

Access to the burned recreation residences is limited as the paved main entrance become a narrow single land native surface road approximately 1 mile before the first burned recreation residence.

The burned debris associated with each structure was for the most part consolidated into the structure’s footprint, making it difficult to fully identify all hazardous materials contained in the burned debris in each location.

The fire also burned parts of structures located at: the Mount Blue Ski Resort.

A description of the burned non-forest service structures is shown below.

Burned Cabins, Outhouses, and Storage Sheds (All three structures located at cabin site burned to foundation)
