Project/Program Permitting

Any person, company or agency planning to conduct certain activities in waters of the United States, or dump or place dredged or fill material into waters of the United States, must first obtain a permit from the Corps of Engineers. Permits, licenses, variances or similar authorization may also be required by other federal, state and local statutes.

Individual Permits are issued after following a full public interest review of an individual application for a Department of the Army permit. A public notice is distributed to interested parties and comments are solicited. After evaluating the comments and information received, the Corps makes a decision to issue or deny a permit based on compliance with its regulations and other laws, as well as a determination that the activity is not contrary to the public interest.

Letters of Permission can be issued following an abbreviated review procedure involving the review of the application for a Department of the Army permit by interested agencies. After evaluating all comments and information received, a final decision is made. If any of the agencies object, an individual permit will be required. Like individual permits, a permit is only granted if the activities are found to not be contrary to the public interest.

The U.S. Army Corps of Engineers, Los Angeles District (Corps) received an application for a permit under Section 404 of the Clean Water Act.  Asarco LLC, the applicant is proposing to construct, operate, and close a tailings storage facility to support continuing copper mining activities at the Ray Mine Complex in eastern Pinal County, Arizona.  The facility would accommodate tailings that would be collected at the mine, transported via a tailings delivery pipeline, and deposited in slurry form at a discharge point east of Ripsey Wash, an ephemeral wash that is a tributary to the Gila River.  The facility footprint is estimated at 2,574 acres and currently has an elevational range of approximately 1,800 to 2,400 feet above mean sea level.  The facility is designed for an overall storage capacity of about 750 million tons of tailings and embankment materials with a final crest elevation of 2,440 feet. The proposed facility would be built with centerline and upstream construction methods.  If approved as proposed by the applicant, the project would result in direct impacts to approximately 130 acres of waters of the U.S. and would indirectly impact an additional 4 acres (approximately) of waters of the U.S. from dewatering.  The Corps has prepared an environmental impact statement to assess the environmental effects associated with this action.

Fact Sheet

Public Notice

28 Feb Mitigation Letter

The Corps has proposed to establish alternative permitting procedures, specifically Letter of Permission procedures, associated with the State of California’s Salton Sea Management Plan 10-year Plan (SSMP 10-Year Plan) and a draft environmental assessment document. This Special Public Notice concerns the proposal to undertake the process to establish new LOP procedures, pursuant to 33 Code of Federal Regulations (C.F.R.) section 325.2(e), which allows the Corps to establish such alternative permitting procedures to address anticipated discharges of dredged and fill material into waters of the United States (U.S.). Specifically, by undertaking the process to establish new LOP procedures for the SSMP 10-year Plan projects, the Corps in coordination with other federal and state agencies and with notice to potentially interested parties, may evaluate the suite of proposed activities more effectively than would be afforded by review on a case-by-case basis. If established, LOP procedures would allow the Corps to authorize SSMP-related activities that would discharge dredged or fill material into waters of the U.S., as regulated under section 404 of the Clean Water Act. The environmental assessment evaluates the proposed actions of six Federal associated with the SSMP 10-Year Plan.

The SSMP 10-year Plan Project Description/Proposed Action proposes to implement 29,800 acres of habitat restoration and dust suppression projects on lakebed areas that have been, or will be, exposed at the Salton Sea by the year 2028. At least 14,900 acres of projects permitted under the SSMP 10-year Plan would be aquatic habitat restoration projects that convert exposed lakebed areas either to pond habitat suitable for fish and wildlife, or to wetland habitats. While all the aquatic habitat projects would suppress dust, their primary function would be to provide habitat for fish and wildlife. Dust suppression projects may also have habitat benefits by establishing vegetation or creating freshwater wetlands on exposed areas, but they would be designed primarily to suppress fugitive dust emissions for improved air quality. Likewise, the SSMP 10-year Plan provides for multiple benefit projects that combine dust suppression with habitat restoration to the extent practicable.

El Cuerpo ha recibido una solicitud del Estado de California para establecer procedimientos de permisos alternativos, específicamente procedimientos de Carta de Permiso (LOP, por sus siglas en inglés), asociados con el plan decenal del Programa de manejo del mar de Salton (SSMP, por sus siglas en inglés) . Éste Aviso Público Especial es para la propuesta de emprender el proceso para establecer nuevos procedimientos de LOP, de acuerdo con la sección 325.2(e) del Código de Regulaciones Federales (CFR, por sus siglas en inglés) 33, que permite al Cuerpo establecer procedimientos alternativos para abordar las descargas de materiales dentro de las aguas de los Estados Unidos (EE. UU.). Específicamente, al emprender el proceso para establecer nuevos procedimientos de LOP para los proyectos del plan decenal del SSMP, el Cuerpo en coordinación con otras agencias federales y estatales y con notificación a las partes potencialmente interesadas, puede evaluar en conjunto las actividades propuestas más eficazmente de lo que se obtendría mediante una revisión de caso por caso. Si se establecen, los procedimientos de LOP permitirían al Cuerpo autorizar actividades relacionadas con el SSMP que descargarían materiales dentro de las aguas territoriales de los EE. UU., según lo regulado en la sección 404 de la Ley de Agua Limpia (CWA, por sus siglas en inglés). La evaluación ambiental examina las medidas propuestas por seis agencias federales asociadas con el plan decenal del SSMP.

La descripción del plan decenal del SSMP/la acción propuesta propone implementar 29,800 acres de proyectos de restauración de hábitat y supresión de polvo en los lechos del lago que han estado o estarán expuestas en el mar de Salton para el año 2028. Al menos 14,900 acres de proyectos autorizados bajo el plan decenal del SSMP serian proyectos de restauración de hábitats acuáticos que convertirían áreas del lecho de lago que están expuestas en hábitats de estanques adecuados para peces y vida silvestre, o en hábitat de humedales. Aunque todos los proyectos de hábitat acuático suprimirían el polvo, su función principal sería proporcionar un hábitat para los peces y la vida silvestre. Los proyectos de supresión de polvo también pueden tener beneficios para el hábitat al establecer vegetación o crear humedales de agua dulce en áreas expuestas, pero estarían diseñados principalmente para suprimir las emisiones de polvo para mejorar la calidad del aire. Asimismo, el plan decenal del SSMP prevé múltiples proyectos de beneficios que combinan la supresión del polvo con la restauración del hábitat en la medida de lo posible.

The Regulatory Division of the U.S. Army Corps of Engineers Los Angeles District developed Special Area Management Plans (SAMPs) for the San Diego Creek and San Juan Creek/Western San Mateo Creek Watersheds in Orange County, Santa Margarita and San Jacinto Watersheds in Riverside County, and Otay Watershed in San Diego County. The purpose of the SAMPs was to develop and implement watershed-wide aquatic resource management plans and implementation programs, which include preservation, enhancement, and restoration of aquatic resources, while allowing reasonable and responsible economic development and activities within the watershed-wide study area. Seven studies completed by the Engineer Research and Development Center (ERDC) used geospatial analysis of landscape-scale data to delineate aquatic resources using a unique planning level delineation procedure, generate a baseline assessment of riparian ecosystem integrity, and develop planning tools using the baseline assessment that identified riparian restoration opportunities within the Santa Margarita, San Jacinto, and Otay Watersheds. Final reports documenting the results of these analyses are provided below.
