Hopatcong HAB

Was having a discussion with someone the other day who lives in the Lake Mohawk Community. They mentioned they have the following policy which you can find on line.

Non-Phosphorous Community:
In a lake community, phosphorous is the NUMBER ONE ENEMY. Phosphorous feeds the algae and the weeds in our Lakes. For that reason, ordinances have been passed in both Byram and Sparta Townships prohibiting fertilizers containing phosphorous and requiring that septic systems be pumped every three (3) years. We also recommend that you use household products, laundry and dishwasher soaps that have no or low phosphorous. Your cooperation is necessary to maintain a healthy ecological lake environment.

Does Lake Hopatcong have a similar policy and if not why not? IF use of phosphorous based fertilizers is the leading cause of HAB, I would think this is a no-brainer relative to what the community is going through this year. Nice lawns are just that nice, but if they're making the community unsafe to it's residents what's the point.
