Soil and Groundwater Pollution Remediation Funds

Promotion System for Sites Requiring Accelerated Remediation

Background

When a site is designated as a Soil and Groundwater Pollution Control Site (hereinafter referred to as a Control Site) or a Soil and Groundwater Pollution Remediation Site (hereinafter referred to as a Remediation Site), the responsible party is required to submit a pollution improvement plan, which must be approved and implemented under the supervision of the local Environmental Protection Bureau (EPB). To safeguard public health and protect environmental resources, the status of listed sites is regularly evaluated to monitor remediation progress. Sites that have failed to undertake remediation measures or have shown prolonged stagnation are collectively referred to as Sites Requiring Accelerated Remediation, for which special attention and resources are devoted to strengthening pollution remediation and management. Since 2017, the EMA has focused on managing and tracking sites with long-term stagnation—particularly those where the responsible party is unknown or has failed to fulfill remediation obligations, groundwater pollution use restriction zone, and sites with delayed progress exceeding six months in the regulatory process. The EMA has provided legal consultations to clarify administrative procedures and guided responsible entities in implementing effective pollution improvement measures.

Implementation Process and Achievements

The EMA has been managing sites requiring accelerated remediation since 2017. To further promote pollution remediation and delisting of these sites, the EMA conducted a comprehensive review in June 2023, identifying a total of 146 sites requiring accelerated remediation. A full-scale analysis was carried out to confirm the responsible parties, assess the extent and severity of pollution, and develop remediation methods and implementation plans, with the ultimate goal of delisting the sites and restoring land use. Given the latent, cumulative, and complex nature of soil and groundwater pollution, it is challenging to promptly complete tasks such as delineating pollution boundaries, assessing contamination severity, initiating remediation, and conducting risk assessment and management. Therefore, the EMA has adopted a central demonstration and local grant approach, collaborating with local governments to advance remediation efforts, provide policy feedback, and ensure the effective and timely completion of remediation and management activities for sites requiring accelerated remediation.

In addition, for sites where remediation has not yet commenced, the EMA implements interim risk control measures to ensure that soil and groundwater pollution does not spread and that health risks remain within acceptable limits. Subsequent pollution remediation must still be conducted in accordance with legal requirements to achieve delisting objectives. The remediation and management strategy is illustrated in Figure 1, and since the completion of the site inventory in 2023, the results can be categorized into two major components.

To comprehensively identify the responsible parties, current land use, and redevelopment potential of the sites requiring accelerated remediation, the EMA completed environmental site assessments for 146 sites by the end of 2024. These assessments serve as the foundation for subsequent tasks, including determining the extent of pollution and planning appropriate remediation actions. For sites where environmental assessments have been completed, the EMA has progressively conducted pollution delineation to develop remediation strategies, evaluate the feasibility of site cleanup, and plan remediation methods and budgets. These efforts facilitate the continued implementation of remediation and management for the sites requiring accelerated remediation. In terms of practical remediation outcomes, the EMA completed a demonstration remediation project at the Dagang Section in Nantou County by the end of 2023. Following verification by the Nantou County Environmental Protection Bureau, the site was officially delisted in May 2024.

To further expand the capacity for pollution remediation and enhance the effectiveness of remediation operations, since 2024 , the EMA has adopted a “Dual-Track Central-Local Remediation Management” strategy to accelerate and amplify remediation outcomes. Under this strategy, the central competent authority formulates strategies and demonstrates implementation (including legal analysis, planning of land revitalization revenue return funds, promotion of sites requiring accelerated remediation, site risk assessment and management, and management of groundwater pollution use restriction zone). Meanwhile, local environmental authorities apply for projects to advance site remediation and management (including routine site management plans, implementation of pollution remediation, risk management, and appropriate measures for groundwater pollution use restriction zone), with the goal to ensure that remediation of sites requiring accelerated action is completed on schedule and in accordance with standards.

Following the aforementioned Dual-Track Central-Local Strategy, implementation has gradually proceeded in 2024. At the central level, the EMA has conducted legal opinions for various sites, facilitated collaboration for land reuse, continuously monitored sites requiring accelerated remediation, and formulated subsidy application guidelines. In addition, demonstration remediation has been completed for one site in the Dagang Section. Regarding subsidies to local authorities, for sites in groundwater pollution use restriction zone, the EMA approved subsidy plans in 2024 for four municipalities/counties—New Taipei City, Taoyuan City, Miaoli County, and Pingtung County—and is currently executing pollution investigations, emergency response measures, and risk management monitoring. For sites undergoing pollution remediation, in 2024 the EMA approved remediation and supervision plans for two sites: No. 54, Subsection 9, Neiwei Section, Gushan District, Kaohsiung City, and No. 1340, Jiuching Section, Jiuru Township, Pingtung County; these projects have been contracted out and remediation operations are ongoing. In July 2025, the remediation plan for No. 55, Subsection 9, Neiwei Section, Gushan District, Kaohsiung City was approved, with contracting and remediation operations currently underway. In terms of risk management, in May 2025 the EMA approved the risk management plan for No. 1458, Xinpu Section, Nantou City, Nantou County. In July 2025, multiple risk management plans were approved for sites in Tong’an Section, South District, Tainan City, and Cheluquan Section, Rende District, Tainan City, with contracting and risk management operations following accordingly.

Future Outlook

Through the continued promotion of accelerated remediation site management, efforts are being made not only to actively resolve long-stalled contaminated sites—thereby safeguarding public health and the ecological environment while restoring land to productive use—but also to integrate implementation experiences into regulatory, technical, and administrative practices. This approach aims to prevent future delays or stagnation in pollution remediation efforts. The long-term objectives of the program are as follows:
