PASSED AND ADOPTED this 2bth day of January, 1993, by the Butte County Board of Supervisors, at Oroville, California by the following vote: AYES: Supervisors Meyer, Dolan, McLaughlin, Thomas, and Chair Houx NOES: None ASSENT: None NOT VOTING: None MARY AN HOUX, Chair Butte County Board of Supervisors ATTEST: JOHN ~5. BLACKLO ,Chief Administrative Officer and Clerk ~ the Boa d upervisors By: EXHIBIT A RICHARDSON SPRINGS WASTE'fi~7ATER IMPROVEMENT PROJECT MITIGATION MONITORING REPORT ISSUE: Water quality IMPACTS}: High rates of infiltration, insufficient capacity of existing ponds to store a I00-year rainfall and effluent. Soils in the spray field have not been tested for suitability to handle nitrogen and organic loading. MITIGATION MEASURER: 1. Measurement of flow rates shall be made in segmented portions, by qualified personnel, at the source of the ma.an sewer line, and at both the upper pond and at the lower pond to determine any fluctuations. These measurements should be performed seasonally and at times of peak usage. 2. a. The spray irrigated area shall be regularly monitored for the amount of nitrogen in the percolate for a period to be established by the CVRWQCB. b. Additional acreage shall be added to the system, with appropriate piping, pump station, storage, and low- level spray system, if nitrogenz loadings or water effluent volumes prove to be too great.

Erasion from the berms may lead to ' sedimentation of Mud Creek. MITIGATION MEASURE ~3, Perineter berms shall be covered with a mulch and/ox planted with appropriate vegetation to hold the soil in place. Exposed areas of berms not properly planted or mulched by the onset of the rainy season (October 15) shall be securely covered with appropriate material to protect the soil fro~u the elements .

The hardpan layer could allow partially treated effluents to surface near the roadway. Cattle trails leading downward across the spray field could collect and drain wastewater on the surface toward the roadway. MITIGATION MEASURE ~5. The spray field shall meet the requirements of the Central Valley Regional Water Quality Control Board, and: a_ The limits of the spray field shall be established on, the basis of an adequate depth of soil as established by staff of the Regional Water Quality Control Board. b. All cattle trails and any minor drainageways leading ' downslope within the spray field area shall be graded out and revegetated to avoid concentrat.ians and short-circuit flows of effluents. c. A collection ditch shall be constructed at the bottom of the spray field that penetrates into the hardpan layer to iza,tercept any surplus surface flows or flows on tap of the hardpan . d. Effluents shall be metered onto the spray field at a rate to be deter~.i,ned in consultation with the Regional Water Quality Control Board.

A Z00-foot no-disturbance buffer area should be established for Mud and Maple Creeks. No new construction or equipment should be placed in. this area.
