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,

TBSA

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
