1. Background/Introduction

Created in 1906, the Washington State Association of Counties (WSAC) is a voluntary, non-profit association serving Washington’s 39 counties.  WSAC members include elected county commissioners, council members, and executives.

The Association provides various services to its member counties, including advocacy, training, workshops, and a forum to network and share best practices.  The Association also serves as an umbrella for affiliate organizations representing county road engineers, local public health officials, county administrators, county planners, emergency managers, county human service administrators, solid waste managers, clerks of county boards, and others.

Counties have direct responsibility for law enforcement, road maintenance, land use controls, planning and permitting, and other administrative duties for the land areas in the county outside of cities (unincorporated lands).  Such lands typically include agriculture, residential, industrial, light commercial, forestry, recreational, or other uses usually found in rural areas.  However, unincorporated lands may also have densely zoned and developed properties that are more urban. They may be designated for such growth anticipating future annexation by a city or historically were characterized by such use.

As growth in areas including denser, urban-style uses expands over time, it may encroach on surrounding pre-existing land uses that are not urban.  Such pre-existing land uses and corresponding practices may not be compatible with dense urban development and may require remediation before conversion.

Tree fruit orchards have been an important economic and cultural resource in Central Washington communities since the late 1800s. Population growth and increasing demand for housing have resulted in the conversion of historical orchard sites to other nonagricultural uses, including residential developments.  Historical application of lead arsenate (LA) pesticides on tree fruit orchards has resulted in the accumulation of lead and arsenic in shallow soil at concentrations above the Washington State cleanup levels.  These are levels that may be harmful to human health when properties are used for activities other than agricultural or industrial uses.[1] Most of the impacted areas are in Yakima, Chelan, Douglas, Okanogan, and Benton counties.

Counties work closely with the Washington State Department of Ecology (Ecology) on numerous issues, including the cleanup of contaminated sites. Ecology is charged with implementing the Model Toxics Control Act (MTCA), the environmental cleanup law for Washington State. Counties are charged with permit issuance authority for most land use, development, and construction activities on properties within their jurisdiction.  As growth in Central Washington counties creates conversion of historical orchard lands, compliance with MTCA where LA pesticide contamination may be present is required.

To address this issue, Ecology established the Legacy Pesticide Working Group (LPWG) in December 2019.[2] The LPWG developed a model remedy to address LA pesticide contamination for new residential development, including specific guidance on soil sampling and cleanup methods.  Some of the cleanup alternatives included in the model remedy rely upon the availability of clean, replacement soils.  One way to ensure clean, replacement soils are available is to create and operate soil banks in the impacted regions.

There are numerous ways to implement the model remedy.  However, to implement it effectively in the most efficient manner, it may need to be incorporated into local government permit review processes and development codes. A permit review process that includes the model remedy should be conducted in partnership with Ecology to ensure applicants meet all legal requirements.

Counties and cities are very diverse, even when located within the same region of the state.  Their development codes and review processes may vary significantly.  However, all counties and cities must meet the same standards for permit review and issuance under state law.  Developing a model code for incorporating the model remedy into the development codes and permitting process of a city or county may greatly assist local governments in working with Ecology. It may also assist applicants in meeting legal requirements for addressing LA pesticide contamination while successfully developing new projects.


2. Project Goals and Scope of Services

There are two goals for this project:

  1. To complete a feasibility study for a system of soil banks to replace or mitigate contaminated soil and/or or supply clean topsoil to address lead arsenate contamination on historic orchard land in Central Washington; and
  2. Develop model codes and processes for local government adoption to facilitate implementation of the Ecology model remedy developed by the LPWG.

The model remedy process encourages property owners not to export contaminated soil, but instead to cap soil with hard surfaces or clean soil. In case there is greater need for clean soil, this project will study and assess the feasibility of a local or regional system of soil banks in Central Washington.  This could include conversion of an existing solid waste facility, an additional use at an existing facility, or a new facility. Uses for the soil banks include:

  1. Accepting and storing lead arsenate contaminated soil; and
  2. Providing clean soil for capping or replacement of lead arsenate contaminated soils.

The feasibility study will also research and document the validity, feasibility, and sustainability of future soil bank locations and operation and maintenance by public, private, or public-private partnership entities. It will include the evaluation of options for the potential beneficial reuse of LA contaminated soil consistent with applicable solid waste regulations.

The minimum elements to be included in the feasibility study are:

  1. Details on total acres of potentially suitable and available sources of clean soil in the Central Washington region.
  2. A complete GIS analysis providing detail on factors that may impact the cost and availability of clean soil in the region, including transportation, storage facility needs and costs, and rates of economic development and growth.
  3. An analysis of public vs. private business and public-private partnership opportunities to provide clean soil, including a clean soil bank, a soil repository, and a soil treatment facility. This analysis should include a regulatory discussion, cost/benefit study of the different business models, including supply and demand, and actionable approaches for Central Washington communities and private interests to achieve such facilities.
  4. A detailed analysis of both clean soil bank facilities and a repository for LA contaminated soils, based on the specific needs of different areas in the regions.
  5. Where soil bank facilities are determined feasible, the analysis should identify potential federal or state grant funding to assist with development and implementation. It should also identify possible locations where LA contaminated soil can be properly disposed or beneficially reused, how to handle precipitates/water ponding, how to retire the soil bank sites that are holding LA contaminated soils, an evaluation of prioritizing the use of clean soil on most LA contaminated properties, the challenges and opportunities of implementing the soil bank concept for both clean locations and repositories for LA contaminated soils, and a discussion of city or county regulatory hurdles that may exist and how they could be addressed, mitigated, or modified.

To facilitate the implementation of the model remedy developed by the LPWG, this project will also create model codes and processes that local government permitting agencies may adopt.  These codes and processes are needed to assist local Central Washington cities and counties in creating a uniform, predictable, transparent, and efficient approach to ensure parcels proposed for development that may contain LA contaminants are identified and properly cleaned up or mitigated as part of development or construction.

The model codes and processes creation must include the following:

  1. A public input process and report, including meetings with the LA Steering Committee, local government planning committees, elected officials, building inspectors, community residents, and others involved in development and construction projects within Yakima, Chelan, Okanogan, Douglas, and Benton counties.
  2. An implementation study of the LPWG’s model remedy in Central Washington, including representative examples for the study, a process or procedure to implement the model remedy in Central Washington communities, identification of which state or local government department in each jurisdiction would “house” the model codes and processes, a determination of how to incorporate the model codes and processes into local regulatory guidelines or existing regulations, an evaluation of both SEPA and SEPA exemption thresholds and process for specific types of property development, recommendations of what might trigger Ecology enforcement or oversight of property development projects, and recommendations for assuring compliance with the model remedy through the issuance of a building permit, certificate of occupancy, plat approval, or other relevant development permit approval.

The selected firm will work collaboratively with WSAC, Ecology, and the Lead Arsenate Model Remedy Implementation Steering Committee (LA Steering Committee) members who will oversee and assist in designing and directing the project.  The selected firm will meet with the LA Steering Committee at regular intervals to provide direction and oversight and receive information.  The selected firm will also be expected to work with local Central Washington city and county planning offices to identify potential locations for LA contaminated and removed soils and clean replacement soils.  The selected firm will also be expected to attend meetings in Central Washington communities to inform and accept comments on the project.

WSAC will finalize a detailed scope of work after Ecology, and the selected firm has an opportunity to consider the project goals, the contractor’s proposal for meeting the goals, and any reasonable limitation that may exist or assumptions that must be made.  The final scope of work will be negotiated between WSAC and the selected firm.

The consultant may outline other items deemed necessary to complete the project successfully.
