Draft Documents for the South Shore WRF (formerly Bay Park STP) and Cedar Creek WPCP Draft SPDES Permits and Bay Park Conveyance Project Directional Drilling

South Shore WRF & Cedar Creek WPCP Draft SPDES Permits

The documents in this section relate to the draft SPDES permits for the South Shore Water Reclamation Facility (WRF) (NY0026450) and the Cedar Creek Water Pollution Control Plant (WPCP) (NY0026859). These draft permits have undergone a full technical review related to the Bay Park Conveyance Project. This project will connect and convey the treated effluent from the South Shore WRF to the existing ocean outfall currently used by the Cedar Creek WPCP.

The documents are available on the NYSDEC's Nassau Conveyance FTP site

Bay Park Conveyance Directional Drilling Project

The documents in this section relate to the directional drilling portion of the Bay Park Conveyance Project in Nassau County, NY. The purpose of the project is to improve water quality in the Western Bays by diverting treated effluent from the South Shore Water Reclamation Facility (WRF) to the existing ocean outfall at the Cedar Creek Water Pollution Control Plant. The permits applied for are:

  • Section 401 - Clean Water Act Water Quality Certification
  • Article 15 Title 5 Excavation & Fill in Navigable Waters
  • Article 24 Freshwater Wetlands
  • Article 25 Tidal Wetlands

The documents are available on the NYSDEC's Nassau Conveyance FTP site:

Draft Renewal Division of Water (DOW) Program Policy 1.3.10 Mercury - State Pollutant Discharge Elimination System (SPDES) Permitting & Multiple Discharge Variance (MDV)

The New York State Department of Environmental Conservation (NYS DEC) is making the draft renewal of the DOW 1.3.10 Mercury - SPDES Permitting & Multiple Discharge Variance (DOW 1.3.10) available for public review and comment.

Draft Renewal DOW Program Policy 1.3.10 Mercury - SPDES Permitting & Multiple Discharge Variance MDV (PDF)

DOW 1.3.10 will provide technical guidance for the development of SPDES permits that regulate effluent containing mercury. This guidance primarily focuses on a MDV for mercury. The MDV was developed in accordance with 6 NYCRR 702.17(h) "to address widespread standard or guidance value attainment issues including the presence of a ubiquitous pollutant or naturally high levels of a pollutant in a watershed."

The MDV is necessary because human-caused conditions or sources of mercury prevent attainment of the water quality standard and cannot be remedied (i.e., mercury is ubiquitous in New York waters at levels above the water quality standard and compliance with a water quality based effluent limit (WQBEL) for mercury cannot be achieved with demonstrated effluent treatment technologies). This MDV is a variance for the WQBEL and is written in accordance with 6 NYCRR 702.17. 

The public comment period ended on November 20, 2020.
