MONITORING
Upstream (Y/N): Y Location: 100 ft above discharge if feasible
Downstream (Y/N): Y Location: at least 00 ft below discharge
Monitor: Temp, Dissolved Oxygen, Cond.
COMMENTS
Facility has already constructed treatment lagoons and is accepting
waste. Dilution ratio to Contentnea Creek is high, so fecal coli will
not be a limited parameter. Recommend existing limits be applied. Also
recommend upstream and downstream monitoring because of possible
impact with Hookerton WWTP. More stringent controls on nutrient inputs
may be required in the future.
