U.S. EPA: Webinar reviewing the Draft Aluminum Aquatic Life Criteria

Training Type(s): Education, Webinar
Date / Time: September 14, 2017 12:00 pm

Thu, September 14, 2017, 2:00 PM – 3:00 PM EDT

On September 14, 2017 from 2:00-3:00 EST EPA is conducting a webinar to review and clarify the recently published draft Aluminum Aquatic Life criteria document (Docket ID: EPA-HQ-OW-2017-0260).

EPA first released freshwater criteria for aluminum in 1988 to protect aquatic life from harmful effects of aluminum toxicity, which can inhibit an aquatic organism’s ability to regulate salt concentrations and clog fish gills, potentially resulting in death or affecting growth and reproduction. EPA is updating the aluminum criteria to better reflect the latest science and in response to a consent decree for Oregon to propose aluminum standards. Studies have shown that three water chemistry parameters — pH, dissolved organic carbon (DOC), and hardness — can affect the toxicity of aluminum by impacting aquatic species’ overall exposure to aluminum. Unlike the fixed values recommended by EPA in 1988 document, this draft document provides users the flexibility to develop site-specific criteria based on a site’s water chemistry. To support the development of site-specific criteria, EPA is providing lookup tables as well as an Aluminum Criteria Calculator.

This event is open to the public. Members of the public, states, tribes, municipalities, waste water treatment plant operators, industry stakeholders, and and NGOs interested in aluminum or the protection of aquatic life will benefit from this webinar.

The public comment period on the draft document closes on September 26, 2017: View and comment on the docket
