Scenarios:“Buildout Loads”
Current Concentrations + Permitted Flows
“Current Loads”
Upper 95th CL of actual monthly average loads
Upgrade Scenario 1: “Uniform Concentration”
All WWTPs set equal to 8.7 mg/L (an upgrade at ~14 of
the 23 WWTPs)
Upgrade Scenario 2: “Upgrade 8”
4 Upper Passaic WWTPs set to 4 mg/L
Harrison Brook, Long Hill, Berkeley Heights, Chatham
Main/Glen
TBSA, Par-Troy, Hanover & Livingston set to 6.5 mg/L
Upgrade Scenario 3: “Upgrade 6”
4 Upper Passaic WWTPs set to 4 mg/L
Harrison Brook, Long Hill, Berkeley Heights, Chatham
Main/Glen
TBSA & Par-Troy set to 3 mg/L

HUCs Significantly over 10 mg/LPeckman River
HUC14 Evaluation
21
Summary of Results
Options to Meet 7.5 mg/L at Intakes
All WWTPs reduce to ~ 9 mg/L
8 WWTPs Upgrade
4 largest upstream WWTPs reduce to 4 mg/L and 4 largest downstream WWTPs
reduce to 6.5 mg/L
Bernards, Long Hill, Berkeley Heights, Chatham Main, Livingston, Hanover, Par-
Troy, TBSA
6 WWTPs Upgrade
4 largest upstream WWTPs reduce to 4 mg/L and 2 largest downstream WWTPs
reduce to 3 mg/L
Bernards, Long Hill, Berkeley Heights, Chatham Main, Livingston, Par-Troy,

Evaluation of Nitrate at HUC Outlets
To achieve 10 mg/L everywhere, dischargers in Dead, Upper
Passaic, and Peckman Rivers need to upgrade to near 10 mg/l.
22
Discussion Points
Can nitrate exceed 10 mg/l at HUC14 boundaries?
PRBA trading program
Trading would be allowed among WWTPs
NJDEP would modify permits where necessary
Protection for WWTPs that trade
