| 2016-31049 | Draft Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity | Notice | The Environmental Protection Agency (EPA) is announcing the availability of Draft Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity for public comment. Elevated ionic concentration measured as specific conductivity has been shown to negatively impact aquatic life in a range of freshwater resources. Once finalized, states and authorized tribes located in any region of the country may use the methods to develop field-based conductivity criteria for flowing waters. This document does not impose binding water quality criteria on any state, but instead provides methods to assist states and tribes that seek to develop such criteria for adoption into their water quality standards. The draft document provides a scientific assessment of ecological effects and is not a regulation. Following closure of this 60-day public comment period, EPA will consider the comments, revise the document, as appropriate, and then publish a final document that will provide methods for states and authorized tribes that they may use to develop water quality standards. | 2016-12-23 | 2016 | 12 | https://www.federalregister.gov/documents/2016/12/23/2016-31049/draft-field-based-methods-for-developing-aquatic-life-criteria-for-specific-conductivity | https://www.govinfo.gov/content/pkg/FR-2016-12-23/pdf/2016-31049.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is announcing the availability of Draft Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity for public comment.
