NYSP2I Direct Assistance Project Task 1: Site Visit Conducted - The project team evaluated
production lines, waste generation areas, and waste storage areas, Dec. 2011
Task 2: Process Info & Data Collected - Identified areas where nitrate is formed and the quantity generated. Information and data provided by Finch Paper:
– Data for completion of the NYSP2I Data Intake Form – Process flow diagrams of the pulp and paper making processes – TRI reporting data for years 2010 and 2011 – Operation data from the wastewater treatment system for 2010 and
2011 – Waste Treatment Costs – SPDES Permit – Policies & Procedures Log – Waste Treatment
Task 3: Waste Assessment and Root Cause Analysis Performed – Performed an analysis to identify the potential key causes of Nitrates from the wastewater treatment plant
Task 4: Presented Focused Assessment Opportunities – Final presentation of findings and recommendations

Nitrate Reduction at Finch Paper • TRI Releases in 2010 = 1.81M lbs Nitrate compounds • NYSP2I evaluated potential to reduce total annual nitrate discharge
to Hudson River from Finch’s on-site Activated Sludge Wastewater Treatment Plant
• SPDES permit does not include a limit for nitrate; TRI reporting is required
• NYSP2I made recommendations for improved operation of Treatment Plant using abundant data provided by Finch – Alter Dissolved Oxygen concentration levels to reduce Nitrates Other recommendations: – Modify the target Food to Mass (F:M) ratio operating parameter – Add Phosphorous to meet bio-growth needs
2010 2011 Potential with suggested controls
Average effluent NO3 (PPY) 1,810,000 1,560,000 421,965
