Introduction to ASTM Committee E64 Stormwater Control Measures

Abstract Submission: In 2021 ASTM established a new committee, E64 Stormwater Control Measures (SCMs), dedicated to developing standard methods and protocols for measuring the performance of SCMs. The committee currently has over 100 members and is regularly producing standards. This presentation provides a brief introduction to E64, our recent activities, and our future plans. Some examples of recent standards include laboratory testing of the performance of hydrodynamic separators (HDS); laboratory verification of filters; and field monitoring of SCMs. ASTM E64 also maintains a set of standard terminology, including terms related to testing, sampling, field monitoring, SCMs themselves, and others. We are also working on draft standards (called work items) on evaluating capture of tire wear particles, measuring hydraulic conductivity of filter media, evaluating wrapped chambers, determining weighting factors for rainfall and climate adjustments, and others. The presentation will discuss future plans for ASTM standards, including field visual inspection, bioretention media sorption capacity, how to include oils and organic material in testing protocols, synthetic stormwater recipes, particle size distributions, and continuous monitoring and adaptive control systems, among others. ASTM E64 welcomes practitioners and academics to join our committees to make standards stronger, more broadly applicable, and relevant to the academic and professional sectors. This presentation will highlight how and why you might want to get involved.

Learning Objectives/Expected Outcome (Optional) : Attendees will learn about existing ASTM standards for assessing Stormwater Control Measures and how they can participate in developing new standards.
