| Objectives | The Nevada County Sanitation District No. 1 owns and operates a wastewater collection, treatment, and disposal system, and provides sewerage service to the community of Lake of the Pines with approximately 1,800 residences. Treated municipal wastewater is discharged to Magnolia Creek, a water of the United States and tributary to the Bear River at the point, latitude 39 degree 02 min 00 sec and longitude 121 degree 05 min 01 sec. The treatment system consists of an unlined aeration pond, two unlined settling ponds, three unlined storage ponds, coagulation and flocculation, sand filtration, chlorination and dechlorination with a
design capacity of 0.72 mgd. Chemical coagulation, flocculation, sand filtration and
chlorination/dechlorination processes are for effluent disposal to Magnolia Creek during wet weather. Spray irrigation to 55 acres of hilly pasture of chlorinated effluent occurs from May through October and dry winter periods. The Discharger requested increasing the limit for pounds per day of BOD and TSS discharged to the creek during wet weather flows. The District would like to take advantage of
the high creek flows to discharge the effluent. Although the discharge pumps have a capacity greater than 0.72 mgd, the chlorination system can only treat 0.72 mgd. Therefore, the discharge is limited to the capacity of the chlorination system and filtration system. However, the Discharger is not restricted to discharging only between November through April. As long as the Discharger continues to maximize
spray irrigation disposal, the Discharger can discharge to Magnolia Creek as necessary. Time Schedule Order No. R5-2007-0072. |
