NOTICE OF AVAILABILITY FOR PUBLIC REVIEW
EPA’s Action to Add Topaz Lake (for Mercury in Fish Tissue) to Nevada’s
2012 List of Waters Requiring a Total Maximum Daily Load

August 4, 2014

The United States Environmental Protection Agency (EPA) is soliciting public comments on EPA’s action to add Topaz Lake (for Mercury in Fish Tissue) to Nevada’s 2012 list of waters requiring a total maximum daily load (TMDL), Nevada’s 303(d) list. On April 14, 2014, Nevada submitted its list of waters requiring a TMDL under Clean Water Act Section 303(d)(2). Section 303(d)(2) requires that states submit and EPA approve or disapprove lists of waters not meeting water quality standards, where existing technology-based pollution controls are not stringent enough to attain, or maintain, state water quality standards, and for which a TMDL must be prepared.

Nevada identified, in its 2012 Water Quality Integrated Report, various waterbody-pollutant combinations as requiring TMDLs. See, 2012 Water Quality Integrated Report, Attachment 4, Category 5 Waters, available at the Nevada Division of Environmental Protection Exiting EPA (disclaimer) web page.

On August 4, 2014, EPA determined that Nevada's list of waters requiring a TMDL partially met the requirements of Clean Water Act Section 303(d), and approved each of the State's listings included in its 2012 Integrated Report, Attachment 4, Category 5 Waters list. During its review, EPA also identified Topaz Lake (for Mercury in Fish Tissue) that met federal listing requirements but was not included in Nevada’s list. Accordingly, EPA has identified one additional waterbody-pollutant combination as requiring a TMDL. EPA’s determination and the waterbody-pollutant listing that EPA has added are available below.

This notice announces EPA’s action to add the waterbody-pollutant listing to Nevada’s 2012 Section 303(d) list. After considering received public comments, U.S. EPA will make any necessary adjustments to its decision and transmit the final list to the state.

All interested persons wishing to comment on EPA’s action to add Topaz Lake (for Mercury in Fish Tissue) to Nevada’s 2012 303(d) list of waters requiring a TMDL may submit written comments to David Guiliano at the email address or postal address below.
