Technical Assistance Agreements
A Technical Assistance Agreement (TAAG) is a contractual agreement between our Northwest Regional Office and participants to clean up contamination at multiple current and former gas station sites. Older gas stations built before 1998 used steel underground tanks and piping which corroded over time and frequently leaked, causing contamination in soil, groundwater, and surface water.
The TAAG program is voluntary and enables participants to work on cleanup of up to 30 sites with our help.
What are the benefits of joining a TAAG?
- Work directly with one designated Ecology Site Manager in the Voluntary Cleanup Program (VCP) to clean up multiple contaminated sites
- Work with us to develop project schedules, deadlines, and to develop efficient strategies to achieve No Further Action (NFA) status
- Contribute to the protection of human health and the environment in the state of Washington
The participant agrees to prepare a portfolio of priority sites for cleanup and agrees to complete appropriate cleanup documents required under the Model Toxics Control Act:
- Remedial Investigation
- Feasibility Study and Disproportionate Cost Analysis
- Cleanup Action Plans
- Long term monitoring plans
Participants also agree to reimburse Ecology for time dedicated to their projects.
We agree to assign a Voluntary Cleanup Program (VCP) Site Manager to each TAAG agreement to provide site-specific technical consultations. We will need to agree to the site portfolio and project schedules.
A TAAG allows sites to efficiently reach No Further Action status. NFA opinions are issued by us when no further remedial action is needed at a site under the state cleanup regulations (Model Toxics Control Act).
