NOTICE OF AVAILABILITY FOR PUBLIC REVIEW
EPA's Action to Add to Nevada's 2014 List of Waters Requiring a Total Maximum Daily Load
April 6, 2016
The United States Environmental Protection Agency (EPA) is soliciting public comments on EPA's action to add a portion of the South Fork of the Humboldt River (for Mercury in Fish Tissue) to Nevada's 2014 303(d) list and revise the location of a previously added listing of the North Fork of the Little Humboldt River (for Mercury in Fish Tissue).
On January 6, 2016, the Nevada Division of Environmental Protection (NDEP) submitted to EPA 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.
In its 2014 Water Quality Integrated Report, NDEP identified various waterbody pollutant combinations requiring TMDLs. See 2014 Water Quality Integrated Report, Attachment 4, Category 5 Waters, available at the Nevada Division of Environmental Protection web site.
On April 6, 2016, 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 2014 Integrated Report, Attachment 4, Category 5 Waters list.
During its review, EPA also identified a portion of the South Fork of the Humboldt River (for Mercury in Fish Tissue) that meets federal listing requirements. EPA also determined that the location of the previously-added listing of the North Fork of the Little Humboldt River for mercury in fish tissue should be revised; to change the location of the impairment to an area further upstream.
This notice announces EPA's action to add and modify waterbody pollutant listings to Nevada's 2014 Section 303(d) list. After considering received public comments, EPA will make any necessary adjustments to its decision and transmit the final list to the state.
CONTACT INFORMATION AND COMMENT DEADLINE
All interested persons wishing to comment on EPA's action to add a portion of the South Fork of the Humboldt River (for Mercury in Fish Tissue) and make a revision of the listing of the North Fork of the Humboldt River to Nevada's 2014 303(d) list of waters requiring a TMDL may submit written comments to David Guiliano at the email address or postal address below.
