Miami-Dade Agrees to $1.6 Billion Upgrade of its Sewer System to Eliminate Sewage Overflows

Under the terms of the consent decree, Miami-Dade will rehabilitate its wastewater treatment plants and its wastewater collection and transmission system within 15 years. The county will also develop and implement management operation and maintenance programs to help ensure the sewer system is properly operated and maintained in the future. By implementing these measures, Miami-Dade is expected to eliminate sanitary sewer overflows from its wastewater collection and transmission system and achieve compliance with its National Pollutant Discharge Elimination System (NPDES) permits.

“Sewage overflows are a significant problem in the Southeast because of inadequate and aging infrastructure,” said Stan Meiburg, Acting Regional Administrator of EPA’s Southeastern office. “This agreement demonstrates the county’s commitment to address its sewage problems. Eliminating overflows of raw sewage will comply with the Clean Water Act and benefit the Miami-Dade community by providing a cleaner and healthier environment.”

“Miami-Dade County is one of the world’s premier resort destinations and is home to America’s Everglades, two aquatic preserves as well as Bill Baggs Cape Florida, Oleta River and The Barnacle Historic state parks,” said Florida Department of Environmental Protection Secretary Herschel T. Vinyard Jr. “This agreement will bring lasting environmental and recreational benefits to the citizens and visitors of Miami-Dade County by reducing the threats posed by untreated sewage overflows that degrade water quality and contribute to beach closures,”

Between January 2007 and May 2013, Miami-Dade reported 211 sanitary sewer overflows totaling more than 51 million gallons. Such overflows included a number of large volume overflows from ruptured force mains. At least 84 overflows, totaling over 29 million gallons of raw sewage, reached navigable waters of the United States. Miami-Dade’s Central District wastewater treatment plant (WWTP) also experienced several violations of the effluent limits contained in its NPDES permit. EPA also documented numerous operation and maintenance violations at this same WWTP during inspections in September 2011, April 2012 and April 2013.

Miami-Dade estimates it will spend approximately $1.6 billion to complete the upgrades required by the consent decree and come into compliance with the Clean Water Act. Under the settlement, Miami-Dade will also pay a civil penalty of $978,100 ($511,800 to be paid to the United States and $466,300 to FDEP) and complete a supplemental environmental project costing $2,047,200.

Miami-Dade’s supplemental environmental project involves the installation of approximately 7,660 linear feet of gravity sewer mains through the Green Technology Corridor, an area that is currently using septic tanks. Businesses in the area have been unable to connect to the sewer system because sewer lines are lacking. Disconnecting industrial users from septic tanks will improve water quality in the Biscayne aquifer and nearby surface waters and prevent future contamination.

The terms and conditions of the settlement announced today will update, replace and supersede two existing consent decrees between the United States and the county, the 1994 First Partial Consent Decree and the 1995 Second and Final Partial Consent Decree. Both of these existing consent decrees will be terminated upon entry of the new, proposed consent decree. The parties to this settlement recognized that since entry of the previous consent decrees, conditions within and circumstances surrounding Miami-Dade’s sewer system have changed over the last 18 years, including the causes and locations of sanitary sewer overflows. As a result, appropriate modifications and updates to the previous settlements are included in the new settlement.

The announcement is the latest in a series of Clean Water Act settlements, including sanitary sewer overflow remediation and combined sewer overflow control plans that will reduce the discharge of raw sewage and contaminated stormwater into U.S. rivers, streams and lakes. It is part of EPA’s national enforcement initiative to keep raw sewage and contaminated stormwater out of the nation’s waterways. Reductions in sanitary sewer overflows are accomplished by obtaining municipal utilities’ commitments to implement timely, affordable solutions to these problems.
