ENB Region 3 Completed Applications 07/06/2005

The applicant proposes to construct two new stream crossings and a stormwater detention basin outfall within a tributary of Masonic Creek (DEC Water Index No. H-139-13-51-3a;  Class B) associated with construction of a 192-unit apartment complex.  The project site is located on the northeast side of Tower Drive, approximately 0.4 mile southeast of the intersection with Scotchtown Road.  The proposed crossings are each about 25 feet wide, and will involve a total stream disturbance of approximately 130 linear feet.  The remainder of the work will involve an additional 330 linear feet of the stream bank disturbance for regrading and installation of a stormwater outfall.  

The applicant proposes to repair/replace 100 linear feet of rock rip rap and add approximately 150 linear feet of new rip rap; and remove approximatley 500 cubic yards of gravel bar along the East Branch Callicoon Creek (Waters Index No. D-53) a Class C(t) stream.  The project site is located on the north side of Dewitt Flats Road approximately 1/2 mile east of Co. Rte 52, in the Town of Callicoon.

The Department of Environmental Conservation has initiated a modification of the State Pollutant Discharge Elimination System (SPDES) permit for the City of Kingston Sewage Treatment Plant (STP.)  This modification is undertaken pursuant to 6 NYCRR Part 1.18, New York State’s  Environmental Benefit Permit Strategy (EBPS).  The following changes to the permit have been proposed:

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 and Ulster County Department of Health 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.

A required Tier 2, Chronic Toxicity Testing and Toxicity Reduction Evaluation Compliance Schedule  have been added to the permit.

CSO (Combined Sewer Overflow) outfalls 003, 004, and 008 have been eliminated as part of the CSO program.  These outfalls have been removed from the permit.

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.

Permit Limits, Levels and Monitoring -

Mass limits - Mass limits for UOD, CBOD5 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 limits for cadmium and action levels for antimony, nickel, mercury and xylenes have been removed from the permit as these parameters have not been detected in the effluent over the past three years.

Lead study- The quantification and removal study for lead was completed and therefore the requirement was removed from the permit.

Added parameters - Limits for copper and lead have been added to the permit as these parameters have been detected in the effluent over the last three years.  

Monitored parameters - Zinc was changed from action level to monitoring 1 /quarter because of very low effluent levels.

Phenolics monitoring - A hi-intensity phenolics monitoring schedule has been added to the permit.  Sampling will be required 1/week  for a period of 3 months to gather data to determine whether phenolics are consistently present in effluent and need to be limited.

Mercury monitoring -  A hi-intensity mercury monitoring schedule has been added to the permit.  Sampling will be required 1/month for a period of 3 months to gather low level mercury data using EPA Method 1631.                                     

Sewer system evaluation study - A sewer system evaluation study compliance action has been added to the permit specifically targets sewers that have experienced deterioration and to rehabilitate the sewers that require work.

    

Plant flow diagram - A new plant flow diagram has been added to the permit.

Influent Sampling -  The influent sampling requirements for 7-day average CBOD5, 7-day average TSS, TKN, fecal coliform,  pH, and temperature have been removed from the permit, as the information is no longer necessary.
