The comment period is the public's opportunity to weigh in on a proposed regulation or proposed permit. This is when the public can provide information, support an initiative, provide technical information, or explain the implications of a rule or section that an agency may not have considered.

In this webinar, learn how to review a proposal, effective ways to structure comments, when to submit an oral versus a written comment, and how you can make the most of the process. Additionally, the Federal and State rulemaking and comment period are not the same. Learn the differences. Discover how to make the most effective comments to support your position and influence the agency’s review.

The Delaware River Basin Commission (DRBC) is excited to announce that it has published a new report, PFAS Water Quality and Fish Tissue Assessment Study – Year 3, and an accompanying interactive tool to support awareness of PFAS in the Delaware River Basin (DRB).  

The DRBC report overviews a three-year study examining average PFAS concentrations in surface water, sediment, fish, and shellfish. The findings conclusively demonstrate that PFAS contamination is widespread, persistent, and increasing downstream in the basin, particularly in tidal waters.  

Join DRBC staff on Monday, June 15th from 12 PM – 1 PM to learn about notable trends and takeaways from DRBC's field investigation and participate in a demonstration of the new interactive application that visualizes PFAS levels across the basin.  

The webinar is free, but registration is required. To register, visit: TinyURL.com/PFAS-Update. Please reach out if you have any questions.
