Effective site closure for Underground Storage Tanks (USTs) is paramount in safeguarding environmental protection and public health. USTs, if improperly managed during or after their lifespan, pose significant risks of contamination to soil and groundwater.
Implementing standardized practices in environmental cleanup ensures consistency, reliability, and effectiveness in mitigating these risks. This guide delves into ASTM's "Moving Sites to Closure" (MStC) standards and explores their application to achieve seamless and efficient site closures.
Overview of ASTM's "Moving Sites to Closure" Guidelines
Introduction to the MStC Initiative
The "Moving Sites to Closure" (MStC) initiative by ASTM is a comprehensive framework designed to streamline the process of UST site closures. Its primary objectives include enhancing site assessment accuracy, optimizing remediation efforts, and ensuring regulatory compliance. The MStC guidelines are developed in collaboration with the Environmental Protection Agency (EPA) and various state agencies, reinforcing the importance of a unified approach to environmental cleanup.
Collaboration and Achievements
Collaborative efforts among ASTM, EPA, and state agencies have significantly advanced UST cleanup operations. To date, thousands of UST sites have been successfully remediated, showcasing the effectiveness of these joint initiatives. However, challenges remain, particularly in dealing with complex contamination scenarios and ensuring long-term monitoring and maintenance.
Insights from the ASTM Webinar
Key Takeaways
A recent webinar hosted by industry experts Greg Dunn (IL EPA), Tom Fox (CO DOPS), and Tom Schruben (US EPA OUST) offered valuable insights into the implementation of the MStC standards. Key takeaways included lessons learned from past cleanup operations, emphasizing the importance of thorough site assessments and adaptive remediation strategies.
Discussions and Draft MStC Standard
The webinar also discussed the draft MStC standard, highlighting its potential to address current challenges in UST site closures. The draft standard incorporates feedback from various stakeholders, ensuring that it reflects the latest advancements in technology and best practices. Participants stressed the need for continuous improvement and collaboration to achieve the shared goal of effective site closure.

Key Considerations and Best Practices
To ensure the success of UST site closures, it’s crucial to focus on foundational elements that drive the process. These considerations are pivotal for optimizing closure strategies, achieving regulatory compliance, and ensuring environmental safety.
Risk-Based Corrective Action (RBCA)
Risk-Based Corrective Action (RBCA) is a cornerstone of the MStC guidelines, providing a structured approach to managing contaminated sites. RBCA involves evaluating the risk posed by contaminants to human health and the environment and tailoring remediation efforts accordingly. This approach ensures that resources are allocated efficiently, focusing on areas with the highest risk.
High-Resolution Site Characterization (HRSC)
High-Resolution Site Characterization (HRSC) is instrumental in identifying the precise distribution of contaminants within a site. By employing sophisticated techniques such as direct sensing and real-time data acquisition, HRSC enables a more detailed understanding of subsurface conditions. This enhanced clarity is crucial for designing effective remediation strategies and minimizing uncertainty.
Innovative Remediation Techniques
In-situ bioremediation and natural attenuation are among the innovative techniques highlighted in the MStC guidelines. In-situ bioremediation leverages microbial activity to degrade contaminants on-site, offering a sustainable and cost-effective solution. Natural attenuation, on the other hand, relies on natural processes to reduce contaminant concentrations over time. Both methods exemplify the commitment to environmentally responsible remediation practices.
Alternative Closure Criteria
ASTM standards also provide alternative closure criteria, allowing for flexibility in achieving site closure. These criteria consider site-specific conditions and the effectiveness of ongoing remediation efforts. By adopting alternative closure criteria, stakeholders can expedite the closure process while ensuring that environmental and public health standards are met.
