Subject: Rocky Mountain National Park East Troublesome Fire Identification and Quantification of Building Debris Memo

Dear Mr. Torcoletti:

BB&E, Inc. (BB&E) completed an inspection of 26 burned structures at Rocky Mountain National Park to assess the type and quantity of building debris in preparation for a Time Critical Removal Action (TCRA). The inspection was conducted on 9/29/2022 and 10/5/2022 in tandem with the soil/ash field sampling event. BB&E identified the following:

• Count, locations, and types of white goods (stoves, refrigerators, water heaters, etc.).

• Count, locations, and types of identifiable hazardous materials (light ballast, chemical containers, drums, compressed gas cylinders, batteries, electronic waste, non-dispersed aerosol cans, etc.).

• Count, locations, and description of suspected or potential hazardous materials or containers that cannot be identified and may require additional evaluation and testing (dispersed aerosol cans).

• Volume of metal debris that may be segregated for recycling (including white goods and other large debris).

• Large debris (metal, etc.) that may be segregated from ash and soil for recycling or disposal.

• Other Notes: Presence of concrete slab, chimney, foundations, stonework, etc.

The inspection forms provided as Attachment A detail the bulleted information above for each former structure.

The inspection forms also include an “other notes” section to provide additional information pertinent to the removal action. Attachment B provides ash/debris removal volumes in tons based on the depth of ash/debris and soil removal volumes in tons which includes six inches of soil removal beneath ash/debris and slab if present. The removal footprint includes the former structure footprint plus a 5-foot perimeter on all sides. Volume of metal debris in pounds was calculated based on total presence of metal that could possibly be recycled including white goods, however some of this metal may be damaged beyond acceptable levels permitted by recyclers. Attachment C provides the location of each structure and Attachment D includes site photographs.

Based on initial site investigation sampling data the following results are available. Please reference to the East Troublesome Wildfire Structural Fire Debris Sites Site Investigation Report for more information.

1. Polychlorinated Byphenols (PCBs) were not detected above the method detection limit for the sites sampled including the Timber Creek Road Camp Barn or the Betty Dick Garage.

2. Hexavalent Chromium was not detected above the method detection limit for the sites sampled including the Timber Creek Road Camp Barn, Fern Lake Ranger Station, or the Betty Dick Garage.

3. Metals and Dioxins/Furans were detected at varying concentrations at all the sites.

4. Elevated metal concentrations above the 20X rule were further tested by TCLP to assess if any of the sites exceeded the TCLP regulatory limits and could be classified as a hazardous waste. Lead was detected at the Timber Creek Road Camp Tack Shed at a TCLP value of 10.3 mg/L, which exceeds the regulatory limit of 5 mg/L.

The information enclosed within this memo has been provided to support removal actions at the 26 burned structures. Removal actions are anticipated to be completed in accordance with a CERCLA Time Critical Removal Action (TCRA) and within the guidelines of the Colorado Department of Public Health and Environment (CDPHE) East Troublesome Wildfire, October 2020 Handouts.

Sincerely, Elyse Kutsche, PE Project Manager
