Application ID: 1-2822-00286/00001
Permit(s) Applied for: Article 17 Titles 7 & 8 Municipal SPDES
Project is Located: North Hempstead, Nassau County
Project Description:
    The State Pollutant Discharge Elimination System (SPDES) permit for the Port Washington Water Pollution Control District’s wastewater treatment plant (WWTP) has been modified in accordance with New York State’s  Environmental Benefit Permit Strategy (EBPS). The WWTP lies on the north shore of Long Island and discharges into Long Island Sound (LIS).

This fact sheet describes the modifications made to the current permit, including the major initiatives, such as the Long Island Sound Total Maximum Daily Loads (TMDL), that were implemented in this modification of the permit. The permit was modified in the following ways:

Permit pages -
  • Updated permit pages are used, based on current Department guidance, format and nomenclature. These include a page of definitions.
  • Permit pages are renumbered and reordered.
  • The address for the Bureau of Water Compliance on the Recording, Reporting and Monitoring page has been changed.
  • The Interstate Sanitation Commission has changed its name to the Interstate Environmental Commission and is referenced thus in the permit.
  • A continuation of the Discharge Notification Act requirements was added.  

Nitrogen -
  • Long Island Sound Nitrogen Limits - The Long Island Sound Total Maximum Daily Limits (TMDL) analysis has been completed for nitrogen and approved by USEPA. Therefore, the requirements of the TMDL, which require point sources discharging to Long Island Sound to reduce the discharge of nitrogen over a period of 15 years, are included in the draft permits as phased limits. These limits are consistent with the 5, 10, and 15 year waste load allocations (WLAs) that are specified in the Zone 10 Nitrogen Load Management Plans. The current nitrogen requirements, found on the page entitled, “Nitrogen Control Requirements for Discharges to Long Island Sound”, have been replaced with updated requirements  necessary for implementation of the TMDL.

    The LIS Zone 10 includes the following permittees:
LIS Management Zone 10, Nassau County - Belgrave, Village of Great Neck, Great Neck District, Glen Cove, Oyster Bay, and Port Washington.

A compliance schedule is included in the permit for Nitrogen, requiring the permittee to identify the methods, operations, and/or facilities necessary to achieve compliance with the incremental limits and the water quality based effluent limit for total nitrogen.

Total Residual Chlorine (TRC) - The current permit has a technology based daily action level of 2.0 mg/l for TRC. A new water quality based effluent limit of 0.65 mg/l has been calculated for TRC that considers dilution, decay, and immediate free available chlorine demand/uptake. Since the treatment plant cannot currently meet the new water quality limit without additional treatment or controls, an interim limit of 2.0  mg/l is in effect until the permittee’s construct facilities necessary to achieve the water quality limits. A compliance schedule requiring engineering design and an implementation schedule is included in the  permit.

Coliform -
The permit has a total coliform limit as a monthly median, 700 #/100 ml, due to shellfishing on the north shore. A footnote details the requirements of this sampling.

The permit requires that the analysis of extra fecal and total coliform sampling each April and August be submitted to DEC due to shellfishing on the north shore. This sampling requirement is detailed in a footnote.

Metals - A compliance schedule has been included in the permit, requiring the permittee to perform three months of sampling for copper and zinc. These metals were found in the sampling that was done for the permit application but more data needs to be generated before a determination can be made to include a limit or action level in the permit.

Miscellaneous -
Influent sampling of settleable solids is removed from the permit. Influent sampling for 7-day average CBOD and TSS is removed from the permit as they are not needed for calculation of % removals.

The temperature limit is now in degrees Fahrenheit for consistency with the water quality standard.

BOD5 limits have been replaced with CBOD5 limits.

Mass limits for CBOD5 and TSS are rounded to two significant figures in accordance with DEC’s Discharge Monitoring Report (DMR) manual.

The permit includes phosphorus and ortho-phosphorus monitoring, influent and effluent, 1/quarter, in accordance with DEC guidance.
