o <br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY -5- <br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY <br /> SAN JOAQUIN COUNTY <br /> INSPECTION REPORT <br /> I <br /> The 95-Acre field was nearly devoid of plant life <br /> (Figure 10). Musco staff stated that the field would <br /> be replanted this winter, probably in December or <br /> January. Drainage from the northern portion of the <br /> field is through another railroad culvert into the pond. <br /> Severe erosion gullies were observed throughout the <br /> field. Regional Board staff requested a copy of the <br /> k: <br /> current Stormwater Pollution Prevention Plan for the <br /> site and suggested that Musco might wish to seek k '�_ ; : Ira <br /> assistance in addressing their erosion control <br /> problems. Musco staff asked if Regional Board staff <br /> E were aware of any consultants in the stormwater field _. <br /> that could be of assistance to them, and Regional <br /> Board staff forwarded a list of three consultants to <br /> Mr. Leikam on 13 October 2406. Figure 10—Field 95 <br /> Field 55 West was observed from the top of the 95-Acre <br /> Rills a a field and from the base of the field near the aerated <br /> reservoir. While NyPa Forage appeared to be living in <br /> this field, growth and spreading were poor. Wattles had <br /> been placed across the slope, but with pre-existing <br />` erosion gullies present for stormwater and tailwater to <br /> Wattles i� ,, .. travel under the wattles, these are ineffective (Figure <br /> �t 11). Musco staff commented that two boxes had been <br /> installed in this field, each designed to allow gravity to <br /> :. return flows to the reservoir. <br /> Growth of NyPa Forage in field 55 East was also <br /> minimal. Standing water was noted along the bottom of <br /> Figure 11—wattles on 55 West the field, next to the bypass channel. <br /> Ten brush aerators were in operation in the reservoir on the date of <br /> the inspection. One additional aerator was beached. A large <br /> sediment delta was observed around the inlet pipe to the reservoir <br /> (Figure 12). When asked by Regional Board staff about removal of <br /> the sediment, Mr. Hall stated that he thought the pond would be <br /> particularly low next summer and that the delta could be scraped <br /> out then. <br /> Figure 12—Sediment Delta in Reservoir <br />
