Compliance and Enforcement

The National Pollution Discharge Elimination System (NPDES) Compliance and Enforcement Program of the Clean Water Act, regulates point source discharges to the nation's waters. NPDES permits can be issued to individual dischargers or can be issued for a group of dischargers (i.e., general permits). Both individual and general permits contain requirements for controlling pollutant dischargers, monitoring discharges, reporting compliance.

Wet Weather Programs are sub-components of the NPDES program, and address wet weather discharges such as runoff from rainfall or snowmelts, and include the following programs: Storm Water Program, Sanitary Sewer Overflow (SSOs) Program, Combined Sewer Overflow (CSOs) Program, and Concentrated Animal Feeding Operations (CAFOs) Program.

Program evaluations of Municipal Separate Stormwater Sewer Systems (MS4) are being conducted to determine permittee compliance with NPDES permit requirements and to evaluate the implementation status of EPA's stormwater regulations. The program evaluations are also being conducted to evaluate the overall effectiveness of the MS4 program. The program reports do not represent a formal finding of violation.

Marin County Sewage Collection Systems - Administrative Orders Issued

The U.S. Environmental Protection Agency today issued enforcement actions requiring nine sewage collection systems in the Sausalito and Mill Valley areas of southern Marin County, Calif. to address chronic sewage spills, improve sewer maintenance and implement long-term programs to renew aging sewer pipes.  The deteriorated condition of the sewer systems became evident in January 2008 when heavy rains overwhelmed the systems resulting in large spills to Richardson Bay and San Francisco Bay.

The EPA enforcement orders were issued to the cities and sanitary districts that convey wastewater to the sewage treatment plants operated by the Sewerage Agency of Southern Marin in Mill Valley and the Sausalito-Marin City Sanitary District at Fort Baker.

    Deteriorated conditions of the sewer systems became evident when heavy rains overwhelmed the systems causing several large sewage spills into Richardson Bay and San Francisco Bay in January 2008.  Rainwater infiltrated into cracked pipes, causing January 25 flows to exceed the capacity of the emergency holding basin at the SASM wastewater treatment plant, where 2.45 million gallons overflowed to Richardson Bay.  Another spill occurred on January 31 when operators at the SASM treatment plant failed to operate all of its discharge pumps leading to a 2.7 million gallon spill to Richardson Bay.  In Sausalito, the January 25 storm led to a 63,000 gallon spill from a sewer manhole on Marinship Way.

    EPA inspections of the collection systems revealed that they have a history of chronic spills.  Most spills are relatively small volume and caused by roots growing into cracks in the pipes.  This pattern of spills is commonly found in aging sewer systems in which many pipes were installed in the 1950’s and earlier.  During winter storms, rainwater leaking into defective pipes leads to even greater problems including large volume spills and disruption of wastewater treatment plants.

    Sewage spills are reported to the State Water Resources Control Board and these reports are available to the public on the Board’s Web site  Exiting EPA (disclaimer).

    The EPA orders require the sewer systems to employ a number of strategies to reduce sewage spills.  In the short-term, the systems are required to implement aggressive sewer cleaning programs aimed at the most problematic pipes.  The systems are also required to inspect their sewer pipes and measure wet weather flows that are passed on to the sewage treatment plants.  Finally, the systems must develop plans to manage excess flows and implement long-term programs to repair and replace deteriorated sewer pipes.

    The wastewater collection and treatment systems in southern Marin County are managed by several small sewer districts and cities.  The small size and fragmented nature of the sewer agencies has made it difficult to adequately fund and effectively manage wastewater.  As the sewer systems have aged and deteriorated, the cost of repair and rehabilitation has increased considerably placing further strain on the small districts and cities. 

    The Sewerage Agency of Southern Marin treats wastewater from about 28,000 people in the Mill Valley area.  The sewage is collected from homes and businesses in networks of sewer pipes that are owned and maintained by five separate sanitary districts and the city of Mill Valley. 

    Sausalito-Marin City Sanitary District treats wastewater from about 16,500 people in Sausalito, Marin City and Tam Valley. 

    With the Orders, EPA encourages the cities and sewer districts to coordinate their responses to the orders and collaborate in actions to finance, operate and renew their wastewater infrastructure.

    EPA and its contractor conducted compliance evaluation inspections of the Marin County sewage collection systems last fall and earlier this year.

Honolulu’s Wastewater Collection and Wastewater Treatment Plants (City and County)
Final Enforcement Order & Consent Decree (2010)

Comprehensive settlement reached between the Federal government (EPA and Department of Justice), Hawaii Attorney General’s Office, Hawaii Department of Health and three environmental groups (Sierra Club - Hawai’i Chapter, Hawai’i’s Thousand Friends and Our Children’s Earth Foundation) with the City and County of Honolulu that addresses Clean Water Act compliance at Honolulu’s wastewater collection and treatment systems.

The settlement includes a comprehensive compliance schedule for the city to upgrade its wastewater collection system by June 2020.  The Honouliuli wastewater treatment plant will need to be upgraded to secondary treatment by 2024.  The Sand Island plant will need to be upgraded by 2035, but could be extended to 2038 based on a showing of economic hardship.

The Consent Decree is currently under review by U.S. District Court for the District of Hawaii and has not yet been approved as final.
