Waukegan Harbor Sediment Cleanup
The first season of dredging of harbor sediment began on September 26, 2012 and ended November 10, 2012. A portion of the North Marina in Waukegan Harbor was removed during the summer of 2012 so that contaminated sediment beneath it could be dredged. Because OMC is out of business, EPA and Illinois EPA are conducting and paying for this second harbor cleanup. A water treatment plant and sediment consolidation facility (CF) were constructed on the OMC Plant 2 property in order to process the contaminated harbor sediment. The treatment plant processes water that is dredged with the sediment and then returns the cleaned water to the harbor. (See diagrams of the dredging and treatment operations under Technical Documents on this page.) The treated water is sampled to insure that it meets clean water standards before it is returned to the harbor. (See the table of water sampling results under Technical Documents on this page.) The CF holds the dredged contaminated sediment. The second season of harbor dredging is planned to begin on April 1, 2013 and conclude in August 2013. A cap will then be placed over areas within the harbor that were too close to the harbor seawall to safely dredge. The water treatment plant is then scheduled to be dismantled and the CF will receive a final cover in 2014.

OMC Soil Cleanup
Most of the contaminated soil and sediment has now been removed; however, areas of contaminated soil remain that either require excavation or will be converted into a containment cell similar to the existing ones created during remedial actions in the early 1990s. Excavation of contaminated soil in the eastern portion of the site is planned to begin in April 2013 and continue until June 2013. Design of the new containment cell in the western Old Die Cast (ODC) area is also planned for 2013. Construction of the ODC containment cell is planned for early 2014. A protective cover is also planned for areas too close to buried utilities to excavate.

OMC Groundwater Cleanup
In September 2011, EPA installed an underground air-sparge curtain treatment system along the south boundary of the OMC Plant 2 property which uses a line of air bubbles released in the groundwater to remove dissolved solvents from the groundwater before it flows off site towards the harbor. The air-sparge curtain system will be operated for at least15 years. In November 2011, a concentrated pool of TCE nearly 28 feet below ground surface was treated with iron filings that were injected into the TCE mass to destroy the TCE so that it cannot be a continual source of dissolved contamination to the groundwater. Treatment of dissolved TCE contamination in site groundwater began in May 2012, by injecting sodium permanganate to break down the TCE into non-toxic components. Groundwater cleanup actions will continue in 2013 with an evaluation of the contaminants in the groundwater followed by additional injections of sodium permanganate.
The former Waukegan Coke Plant portion of the OMC Site is currently under a monitored natural attenuation remedy for residual groundwater contamination left after the significant contamination was removed.

Waukegan Harbor Cleanup

Final preparations for dredging of harbor sediment have begun.  Harbor dredging is planned to begin in September 2012 and to be complete by fall 2013.  Construction of a water treatment plant and sediment consolidation facility (CF) on the OMC Plant 2 property began in March 2012.  The treatment plant will process water that is dredged with the sediment and then return the cleaned water to the harbor.  The CF will hold the dredged sediment.  Additionally, a failed portion of the harbor seawall is currently being replaced in order for the seawall to support dredging operations.  Later in summer 2012, a portion of the North Marina in Waukegan Harbor will be removed so that contaminated sediment beneath it can be dredged.  Because OMC is out of business, EPA and Illinois EPA are conducting and paying for this second harbor cleanup.

OMC Plant 2 Cleanup

Most of the contaminated soil and sediment has now been removed; however, areas of contaminated soil and sediment remain that may require alternative cleanup methods.  EPA plans to present alternate cleanup plans for these areas to the public for comment in July 2012.

Treatment of dissolved TCE contamination in site groundwater began in May 2012, by injecting sodium permanganate to break down the TCE into non-toxic components.  This continues the ground-water cleanup effort that began last year.  In November 2011, a concentrated pool of TCE nearly 28 feet below ground surface was treated with iron filings that were injected into the TCE mass to destroy the TCE so that it cannot be a continual source of dissolved contamination to the ground water.  In September 2011, EPA also installed an underground air-sparge curtain treatment system along the south boundary of the OMC Plant 2 property.  The air sparge curtain uses a line of air bubbles released in the groundwater to remove dissolved solvents from the ground water before it flows off site towards the harbor.  The air-sparge curtain system will be operated for at least 15 years.

Limpieza del Puerto de Waukegan

Los preparativos finales para dragar el sedimento del puerto han comenzado. El comienzo del dragado se tiene previsto para septiembre de 2012 y el final para el otoño de 2013. Una planta de tratamiento de agua e instalaciones para la consolidación de sedimentos se comenzaron a construir en el predio de la Planta 2 de OMC en marzo de 2012. La planta de tratamiento procesará el agua dragada con el sedimento para devolverla limpia al puerto. Las instalaciones retendrán el sedimento dragado. Además, se está reemplazando actualmente una porción averiada del malecón del puerto para que apoye las operaciones de dragado. En el verano de 2012 se retira una porción en el norte del puerto de Waukegan para poder dragar el sedimento contaminado bajo el mismo. Puesto que la OMC ya no existe, la EPA y la EPA de Illinois están realizando esta segunda limpieza del puerto y sufragando sus costos.

Limpieza de la Planta 2 de la OMC

La mayor parte de la tierra y el sedimento contaminado se ha retirado; sin embargo, aún hay áreas contaminadas que podrían necesitar métodos alternativos de limpieza. La EPA tiene previsto presentarle al público los planes alternativos de limpieza de estas áreas para que dé su opinión en julio de 2012.

En mayo de 2012 comenzó el tratamiento del agua subterránea del sitio, contaminada por TCE disuelto, mediante inyección de permanganato de sodio para descomponer el TCE y convertirlo en componentes no tóxicos. Esto constituye parte del esfuerzo por descontaminar el agua subterránea que comenzó el año pasado. En noviembre de 2011 se trató un pozo concentrado de TCE que se encuentra aproximadamente 28 pies debajo de la superficie inyectándole limadura de hierro con el fin de destruirlo para que no continúe siendo una fuente de contaminación disuelta del agua subterránea. En septiembre de 2011 la EPA también instaló un sistema de tratamiento. Se trata de una cortina de burbujas de aire colocada en el subsuelo a lo largo del linde sur de la propiedad de la Planta 2 de la OMC. La cortina consiste de una manguerita que libera burbujas de aire en el agua subterránea para removerle sus solventes disueltos antes de que fluya fuera del sitio hacia el puerto. El sistema de cortina de burbujas de aire estará funcionando por lo menos por 15 años.
