COA Raises Questions on Environmental and Development Impacts of Proposed Ocean Outfall for Bay Park Sewage Treatment Plant at Public Hearings

The State of New York announced on April 23 that three public hearings would be held on Long Island in May to gather information and input from scientists, engineers, local government representatives, environmental groups, and the public on how to improve coastal resiliency and wastewater infrastructure on Long Island.  

One of the most controversial issues presently up for discussion is the proposed construction of an ocean outfall pipe at the Bay Park Sewage Treatment Plant, located in Nassau County.  In addition to relocating the outfall from the Western Bays to the ocean, the current proposal includes conversion of two smaller treatment plants in the area to pumping stations, which would send their wastewater to Bay Park for ultimate ocean discharge.  

COA delivered the following oral comments during the third of the three meetings, held on May 28 at the Suffolk County Community College:

Good afternoon.  Thank you to the panel for inviting the public here today to offer their comments.  My name is Cassandra Ornell and I work as staff scientist for Clean Ocean Action, a non-profit organization.  Clean Ocean Action’s mission is to improve the marine water quality off the New York and New Jersey coasts.  We’ve been working to clean up these shared waters for over 30 years now.

I’d like to share some thoughts on the proposed ocean outfall for the Bay Park Sewage Treatment Plant today.  From what I’ve heard and read, it seems like we are in agreement that the Western Bays are suffering – we’ve seen this problem time and again here on Long Island as well as in New Jersey, as John Weber from Surfrider discussed.  These problems are caused by an excess of nutrient loads entering the waters, which is oftentimes linked to excessive development.

This is a problem that certainly deserves our attention, and we support the upgrading of the Bay Park Plant to tertiary treatment and denitrification of the effluent.

However, the call for an ocean outfall pipe concerns us, for several reasons.
1) The Bay Park plant currently discharges 58 million gallons per day, with a capacity of 70 million gallons per day.  What ecological impacts will relocating this source of freshwater input to the Bays have on Bay salinity and ecosystem functioning?
2) On the ocean side – have studies of localized ecological and physical impacts to the marine environment in the area of the proposed ocean outfall pipe been done?  Where will the currents take this effluent?  How will localized salinity changes impact the marine ecosystem?  What species or habitat types are present in this area?
3) Freshwater is already very scarce on Long Island – we are depleting our aquifer and saltwater intrusion is a major concern.  Given this backdrop of freshwater scarcity and aquifer depletion, I have two questions:
                a) What will be done to ensure the expansion of the plant will not increase sprawl and further aquifer depletion?
                b) How can we reasonably throw away over 50 million gallons of highly treated freshwater daily?  Once freshwater is discharged to the ocean, there is no getting it back.

This proposed destruction of invaluable freshwater resources is a huge waste.  Not to mention the estimated $690 million dollars it would cost – just to build a long pipe out to the ocean.

As such, Clean Ocean Action would like to voice our support for recycling of the treated effluent from the Bay Park plant.  I urge the County, State, and Federal agencies to fully explore all options for water recycling, including aquifer recharge, potable and non-potable reuse, and surface water and freshwater wetland recharge.  These alternatives should be evaluated now, before moving forward with a decision on the ocean outfall pipe.  

Instead of pushing our problems out to sea, let’s spend those nearly 700 million dollars on a green, sustainable solution that employs efficient use and reuse of our freshwater resources.  Long Island is at a critical juncture now, and has the chance to choose a more sustainable path and serve as a model for other communities. 
  
As the discussion continues, it is essential that we all recognize this as a dilemma.  While an ocean outfall may be preferred by some, ocean dumping is nothing to celebrate.  The rally cry for an ocean outfall should be tempered with the reminder that many of us have long worked to keep harmful pollution out of the New York bight.  Though cleaner than in the past, this little pocket of the ocean is suffering too - it's downstream of the most densely populated region in the US, at the receiving end of billions of gallons of wastewater, and is weakened by the adverse effects of climate change. 

The Governor’s office will host a fourth meeting in June (date and location TBD) to announce their recommendations for improvement of wastewater and septic system issues on the island.  For more information on meetings held to date, how to submit your own comments, and the schedule for the final meeting in the series, click here.

NY/NJ Wastewater Treatment and Water Quality Post-Sandy

Wastewater Treatment

Superstorm Sandy’s 14 foot storm surge was devastating to many wastewater treatment facilities and wastewater pump stations.  Raw sewage was released in New York City, Long Island, and northern New Jersey waterways (and  communities, in some cases).

The discharge of millions of gallons of raw sewage contaminated some of the coastal waters of the Hudson and Raritan River Estuaries and Long Island back bays. These waters all flow to the ocean. Over time, much of this sewage has been diluted and/or sunk to the river beds and seafloor. 

Fortunately, most of the treatment plants are back online and functioning again.  However, wastewater infrastructure problems will take years and billions of dollars to fix, according to a recent New York Times article.  Many parts of the metropolitan area along the Hudson in both NJ and NY have old infrastructure and combined sewer overflows (CSOs) that routinely discharge raw sewage when it rains.  Moreover, a lot of plants and pump stations are located in low-lying coastal areas, which are vulnerable to flooding.  Precautions need to be taken to avoid damage and public health risks in future storms.  NY/NJ residents also need to take precaution to avoid waters that may pose health risks.

Water Quality

Recent water quality testing indicates that NJ ocean waters and several bay waters are now relatively clean again, with the exception of certain areas described in more detail below. The EPA found low levels on November 6 in NJ northern ocean waters, and the Monmouth County beach testing from Nov. 19 showed fairly low fecal bacteria levels at ocean beaches. DEP has shellfishing data that indicated problems in the northern NJ Bayshore and northern part of Barnegat Bay following the storm, and improved water quality conditions since then.  


However, shellfishing is still closed in the northern Bayshore (Raritan Bay and Sandy Hook Bays) due to water quality concerns. Shellfishing is also still closed in some other areas, such as Barnegat Bay, because shellfish were contaminated by sewage during the storm and have not been able to depurate (or filter out) the potential pathogens yet due to low water temperatures which slowed the shellfish’s metabolism and filtration activity. Shellfishing closures are also still in place in New York.   

Also, based on the most recent sampling on November 29 (which is not yet posted online), EPA strongly advises “that people avoid activities that could bring them into direct contact with the waters in Newark Bay and New York Harbor.”  EPA is advising people to avoid waters “in and around the tidal Raritan River/Washington Canal and Raritan Bay area.” EPA is also still warning that the public should avoid waters near and around the Bay Park wastewater treatment plant in Nassau County.  

Be Cautious 

Although many waters have improved, please take precaution, avoid areas near where raw sewage was released, and avoid swimming or surfing after heavy rainfall as there still may be health risks present. (Sewage may also be health hazard in homes that were flooded.)  Be sure to wash with soap and water if you think you did come in contact with contaminated water.  Surfrider has also set up an Ocean Illness Reporting forms.  If you swim or surf in NJ, click here.
