Thurston County 's Hazardous Waste Program provides pollution prevention assistance and regulates businesses that handle, store, or generate hazardous materials or waste.  The goal of this program is to incentivize businesses to adopt best management practices that reduce or eliminate the use of hazardous chemicals.

Hazardous Waste Program Roles and Regulations

Thurston County's Hazardous Waste Management Plan.

Thurston County's Nonpoint Source Pollution Ordinance (Article VI of the Sanitary Code).

Washington State Administrative Code WAC 173-350-360 Moderate Risk Waste Handling.

Hazardous Waste Management Plan Public Survey

Thurston County is committed to its mission to reduce or eliminate exposure to hazardous materials while protecting and preserving human health, environmental quality, and natural resources. We are working to better understand what types of hazardous wastes are present in our community, how hazardous materials are currently managed, and what program improvements we could make to better serve our residents. This information will help inform our Hazardous Waste Management Plan.

Your input is vital as we plan for a healthy future in Thurston County. Survey responses will be anonymous. We appreciate your time and participation! Take the survey here.

Business Pollution Prevention Technical Assistance

Thurston County Hazardous Waste Program participates in the Pollution Prevention Partnership which is comprised of representatives from cities, counties, and health departments across Washington. The program is funded through the Department of Ecology and provides free technical assistance to businesses that generate, handle, or store hazardous materials or waste. 

Our technical assistance visits are designed to reduce or eliminate hazardous waste and pollutants at the source. A local pollution prevention specialist will meet with your organization to evaluate current activities and practices. They will discuss concerns, observations, solutions, and work directly to help solve common challenges around dangerous wastes, stormwater, solid waste, and spill prevention. This collaborative process limits liability, reduces risk, and improves work environments.

To read reports on previous campaigns, see Pollution Prevention Assistance Campaigns below. Examples of businesses we visit include different types of automotive shops, commercial printers, dental offices, dry cleaners, school laboratories, auto recyclers, and paint contractors.

When working with a business, our goal is to bring the business into compliance with the Thurston County's Nonpoint Source Pollution Ordinance (Article VI of the Sanitary Code) and provide them with the appropriate resources for correctly managing their waste streams in the future. If we observe practices or physical handling and storage methods that need to be changed, we'll set up a time to have changes made, and return for a follow up. Formal enforcement action is not our preferred method for bringing businesses into compliance with the ordinance.

When a business is determined to be in compliance with the county ordinance, they are given a Notice of Compliance (NOC), describing their general waste stream managed, the amount managed per month, and how they have chosen to manage the waste.

If a business is not in compliance with the ordinance at the conclusion of the initial visit, they are provided a Notice of Non-Compliance (NONC), which describes what wastes or products need to be addressed in order to be in compliance.

Most businesses that we work with are pleased with the outcome of our visits. Though some businesses may have to invest in pollution prevention equipment or supplies to satisfy the requirements of the Nonpoint Source Pollution Ordinance.  Many are already in compliance before our visit or are able to make simple changes to properly manage their waste streams.

Thurston County PHSS Environmental Health has conducted several voluntary pollution prevention industry campaigns to help Thurston County businesses understand and comply with the County's Nonpoint Source Pollution Ordinance,(Article VI)Our philosophy about pollution prevention is to promote the use of effective less-toxic chemicals in industry.   Our program staff work with Department of Ecology to provide vouchers and financial incentives to promote chemical substitution in specific industry sectors.  When we start a new incentive program, we contact every business in the county and offer all the opportunity to utilize the voucher program. 

At the end of a pollution prevention visit, each business will receive a checklist of non-regulatory best management practices (BMP) that are aimed at reducing or eliminating hazardous chemicals and their impacts to human health and the environment. Specialists will note which BMPs are currently in place at the business, as well as which ones are recommended.  The waste reduction techniques can go a long way in improving your business.

Automotive Services

The automotive services campaign focused on commonly generated wastes streams, which include used oil, antifreeze, solvents, and paint-related waste. Technologies that allow for the use of non- or less-toxic cleaners were emphasized, as were proper storage, disposal or recycling of waste materials. Additionally, aqueous parts washers, spill prevention and secondary containment were highlighted. For more information, please see the following:


This campaign helped Thurston County nurseries, including tree and turf farms, become aware of environmental and public health risks from improper storage, use, or disposal of hazardous materials. The primary issues were disposal and secondary containment. To find out more, visit the links below:
