Notice of Availability of Final Designation of Certain Stormwater
Discharges in the State of New Mexico Under the National Pollutant
Discharge Elimination System of the Clean Water Act
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Regional Administrator of the Environmental Protection
Agency Region 6 (EPA) is providing notice of the availability of EPA's
final determination that storm water discharges from the Los Alamos
Urban Cluster (as defined by the 2010 Decennial Census) and Los Alamos
National Laboratory (LANL) property are contributing to violations of
New Mexico water quality standards (WQS) and require National Pollutant
Elimination System (NPDES) permit coverage under the Clean Water Act
(CWA). This action is in response to a June 30, 2014 petition filed
with EPA by Amigos Bravos entitled ``A Petition by Amigos Bravos for a
Determination that Storm Water Discharges in Los Alamos County
Contribute to Water Quality Standards Violations and Require a Clean
Water Act Permit.''
DATES: EPA's Designation Decision and Record of Decision in Response to
Petition by Amigo Bravos for a Determination that Stormwater Discharges
in Los Alamos County Contribute to Water Quality Standards Violations
and Require a Clean Water Act Permit (``EPA's Decision Document'') was
signed on December 16, 2019.
ADDRESSES: For further information contact Ms. Evelyn Rosborough via
email: [email protected], or may be mailed to Ms. Evelyn
Rosborough, Environmental Protection Agency, Water Division (6WQ-NP),
1201 Elm Street, Suite 500, Dallas, TX 75270.
SUPPLEMENTARY INFORMATION: EPA is providing notice of availability of
its final determination that stormwater discharges from MS4s located in
the portion of Los Alamos County within the Los Alamos Urban Cluster
(as defined by the 2010 Decennial Census) and on Los Alamos National
Laboratory (LANL) property within Los Alamos County and Santa Fe County
are contributing to violations of New Mexico water quality standards
(WQS) and require NPDES permit coverage. EPA's final designation
determination is made pursuant to the authority of CWA Sec.
402(p)(2)(E) and 40 CFR 122.26(a)(9)(i)(D) and 122.26(f)(2). CWA Sec.
402(p)(2)(E) and 40 CFR 122.26 (a)(9)(i)(D) allow EPA to designate for
NPDES permit coverage stormwater discharges that EPA determines are
contributing to violations of WQS, but are not otherwise required to be
permitted under EPA's stormwater regulations.
Details of EPA's final designation determination are available in
EPA's Decision Document. EPA's Decision Document and ancillary
materials may be viewed on the EPA Region 6 web page at https://www.epa.gov/npdes/epas-residual-designation-authority.
