Results

The East Fork Community Coalition, led by Dick Leeuwenburg and Marie Ogier,  teamed up with AGU scientists to evaluate potential risks associated with the proposed expansion of the Yacolt Mountain Quarry.  The resulting output for this first phase of an ongoing project included compiling evidence-based recommendations to include in a package submitted to Clark County on behalf of EFCC to ensure the safety of residents in the area of quarry. In response to the concerns outlined in the “Description Section,” the items below contributed toward ongoing efforts of the EFCC.

  • Phase 1: An analysis of dust collected inside a home in Battle Ground, WA found dust particles with characteristics similar to Woolly Erionite, a naturally occurring asbestos. When airborne, Woolly Erionite can be inhaled where the fibers become lodged in the lungs, causing respiratory, cardiovascular and increased cancer risk. Residents are concerned that the Woolly Erionite may be associated with the mining activity.
    • At the appeal of Marie Ogier, member of EFCC, an EPA assessment related to Erionite was completed. The findings were described in the EPA report here.
    • Soil chemistry & review of EPA assessment completed by Scientific Team member Dr. Alyssa Shiel
  • Phase 2: Compilation submitted to county included recommendations related to:
    • Surface & Groundwater, with support from Dr. Halle Morrison
    • Noise pollution risk, with support from Dr. Mathias Basner
    • Geotechnical analysis/landslide risk, with support from Dr Joseph Wartman

Questions and recommendations related to the above topics was submitted to the county in early 2021. Future work on this project may include completing full assessments on the ground to evaluate potential risk to community members in more detail and ensure families in the area stay safe.

Description

Clark County is a county in the southwest corner of Washington State with the Columbia River defining its southern and western borders. Outside of its most populous area of Vancouver, WA, majority of the county is rural and forested. Nested between the Cascade Mountains and the Pacific Coast, the East Fork of the Lewis River, a tributary to the Columbia, cuts through the northern part of the county and provides cold water habitat for endangered Pacific salmonids. Community members describe their home as beautiful and note that their rural lifestyle provides both privacy, a quiet retreat, and endless opportunities for outdoor recreation.

Over the past five years, community members have voiced concerns about the environmental and health impacts from nearby Yacolt Mountain Quarry, where volcanic rock is mined and crushed into gravel and other aggregate. Approximately 1,300 homes are located within 2 miles of the quarry and have complained of loud blasts rattling their homes. Dust and noise generated from the mining operations and truck travel disturbs residents on a daily basis. Residents are also concerned about the impact of the mining on the local aquifer which supplies drinking water and the health of critical salmonid streams. There is a general concern about the impact of the mining operations on drinking water supplies. Dust settles out in people’s homes and there is increased concern over the risk of landslides from the operations. The 2014 mudslide that killed 43 people in Oso, WA remains fresh in people’s memories.

In December 2018, the Clark County Council approved the expansion of the mine to the south to store overburden. Concerns over the quarry’s impacts have only deepened and residents have organized to focus more attention on the issue. An analysis of dust collected inside a home in Battle Ground, WA found dust particles with characteristics similar to Woolly Erionite, a naturally occurring asbestos. When airborne, Woolly Erionite can be inhaled where the fibers become lodged in the lungs, causing respiratory, cardiovascular and increased cancer risk. Residents are concerned that the Woolly Erionite may be associated with the mining activity.

The recently established East Fork Community Coalition (EFCC) is dedicated to protecting families and homes along the East Fork of the Lewis River. They do this by sharing information and communicating concerns about issues facing the area. EFCC’s goal for this project is to gain new information about the impacts that the Quarry is having on the environment and residents in the area. This includes understanding the composition and source of the dust that settles out, how the dust is generated, the risks of continued mining to drinking water, and the potential for landslides.

The first priority for this project will be to engage with a scientist to further understand the composition and source of the dust. Other priorities will addressed in later phases of the project.

Project Impacts: Beneficiaries include community members of all ages who reside near the quarry as well as the natural resources and assets across the landscape. Health risks will be lowered, and the expectation is that the community will know how to mitigate exposure to any risks that the quarry operations may pose. By bringing the community together around a common goal, the community leaders will be able to bring the needs of this community to the forefront of policy- and decision-makers.

Project Outputs:

Outputs include:

  • Maps (spatial representation of environmental data)
  • Reports (to be used in negotiating with local politicians)
  • Educational materials to be used in the community

Agency testing reveals no harmful minerals in Yacolt Mt. Quarry samples

A recent study by the Southwest Clean Air Agency (SWCAA) and EPA has found no erionite present in 12 locations sampled in and around the mine site.
