The Department has initiated a modification of this State Pollutant Discharge Elimination System (SPDES) permit for the City of Newburgh Sewage Treatment Plant (STP.) The permit has been modified in accordance with 6NYCRR 750-1.18, New York State’s  Environmental Benefit Permit Strategy (EBPS).

Permit pages -

Updated permit pages are used, based on current Department guidance, format and nomenclature.

Permit pages are renumbered and reordered.

The address for the Bureau of Watershed Compliance on the Recording, Reporting and Monitoring page have been updated.

A continuation of the Discharge Notification Act requirements was added.  

The pretreatment program language has been updated to require continuation of the program and annual reporting.

The CSO BMP (Best Management Practices) language has been updated to include all 15 BMP’s along with the LTCP (Long Term Control Plan) requirements in accordance with EPA’s national CSO control policy and the wet weather water quality act of 2000.

The toxicity testing requirements and footnote is now included in the permit limits, levels and monitoring page.

Permit Limits, Levels and Monitoring -

Mass limits - Mass limits for BOD₅ and TSS were rounded to 2 significant figures in compliance with DEC guidance in the DMR Manual for Completing the Discharge Monitoring Report for the SPDES, NYSDEC, February, 2002.

Removed parameters- The action levels for methylene chloride, tetrachloroethylene, and chloroform have been removed from the permit as these parameters have not been detected in the effluent over the past three years.

The previous permit required a high intensity sampling schedule for methylbenzene sulforanide. Those results were non-detectable in plant effluent and methylbenzene sulforanide has been removed from this permit.

Added parameters - New acute and chronic toxicity testing requirements have been added to the permit.

Monitored parameters - Zinc, chromium and silver have been changed from action levels to monitoring 1 /quarter because of very low effluent levels.

Bis (2-ethylhexyl) Phthalate monitoring - A hi-intensity Bis (2-ethylhexyl) Phthalate monitoring schedule has been added to the permit.  Sampling will be required once per week  for a period of 3 months to gather data to determine whether Bis (2-ethylhexyl) Phthalate is consistently present in effluent and needs to be limited.

This new State Pollutant Discharge Elimination System (SPDES) permit was drafted for the  Kensico Small Hydro Power Facility operated by the New York Power Authority. The facility has been in operation since 1983, however additional review of the facility by DEC has revealed the need for a SPDES permit at this site.  The subject application was required per an Order on Consent, case number 3-20020321-43 and was duly submitted to the NYSDEC on 03 January 2005.  The permit authorizes the surface discharge of non-contact cooling water from this small elecrtical generation facility to the Kensico Aquaduct/Reservoir.  The permit includes monitoring requirements for total flow, oil/grease and temperature.

A draft permit is available for review at the NYSDEC central office in Albany.  SPDES Number NY 026 8178.
