The recent U.S. Supreme Court judgement in County of Maui, Hawaii vs. Hawaii Wildlife Fund, has opened the door for new groundwater quality compliance requirements for facilities where there is a functional equivalent of a direct discharge. While this issue is still in its early stages of development, it has the potential to impact operations where groundwater quality is influenced by industrial activities, such as pits excavated below the water table or surface impoundments. This presentation will describe the possible impacts on regulatory requirements as the case law is implemented by states and will present methods and technologies to characterize and mitigate compliance risks associated with the groundwater/surface water interface.
The presentation is divided into three sections: 1) Summary of the Supreme Court decision and its possible regulatory impact; 2) Description of modeling tools and methods to characterize compliance risks and evaluate monitored natural attenuation alternatives for compliance; and 3) Discussion of semi-passive treatment technologies for mitigating compliance risks at the groundwater/surface water interface. Each section will last 15 to 20 minutes, followed by Q&A at the end.
The webinar will address such questions as:
- What is a functional equivalent of a direct discharge, and what conditions might lead to this equivalency?
- What tools can be used to evaluate functional equivalency and the effect of natural processes on compliance risks?
- How can semi-passive treatment technologies help reduce and manage compliance risks?
- What strategies can be used to improve reliability and control of passive treatment technologies in cold climates?
