Alternative Hydrogeologic Evaluation (AHE) Process Webinar Series

Susquehanna River Basin Commission

Webinar Dates: January 27th, February 24th, March 24th, 2022 1pm

If you have a SRBC renewal due within the next 5-7 years, or have a client that does, you need to learn about the new Alternative Hydrogeologic Evaluation (AHE) policy! To learn about the new AHE, join SRBC staff for this three-part webinar series that will provide in-depth instructions and guidance regarding the new AHE Policy.

The AHE, which has recently replaced the SRBC’s Aquifer Test Plan Waiver practice, is the first step of a two-step process for submitting a groundwater renewal application to the SRBC. Special focus will be provided on how this new streamlined, risk-based approach utilizes existing data and information to evaluate a withdrawal’s sustainability, impacts to other users, and impacts to the environment.

Through this series of webinars, SRBC staff will provide guidance to:
  • Accurately prepare an AHE.
  • Effectively utilize and evaluate existing site-specific information during the risk-based review process.
  • Identify and fill data gaps.
  • Assess hydrogeologic setting.
  • Consider, evaluate, and assess the three Principal Risk Factors:
    • Sustainability
    • Impacts to Other Users
    • Impacts to the Environment
  • Develop an Action Plan similar to Voluntary Action Plans (VAPs).

You can register for Parts 1, 2, or 3 individually, in combination, or the entire series during the open registration period. Register here!

Part 2 – AHE Process: Evaluating Sustainability and Impacts to the Environment
Thursday, February 24th, 2022 (1:00 - 2:00 pm)

The two remaining risk factors, sustainability and impacts to the environment, are normally the most difficult to assess and resolve. You need to know if your source is reliable at the requested rate and we need to know what environmental resources may be impacted by the withdrawal.

The second webinar will:

  • Describe how the SRBC evaluates sustainability;
    • Demonstrate how groundwater availability analyses, historical testing data, and operations data are used to evaluate sustainability;
    • Identify common data gaps, as well as potential methods to fill data gaps
  • Describe how environmental assessments should be completed to identify environmental resources near your project;
    • Review the coordination process with other agencies;
    • Inform how the results of the environmental assessments are used to guide additional work, as needed.
