This effect is not unusual and has been calculated and observed in other projects. <br /> Omelet House Restaurant Wastewater Effluent Testing <br /> The Omelet House has been operating as a restaurant for more than 30 years. The restaurant's <br /> septic system consists of grease interceptor tanks to retain the fats, oils and grease (FOG), <br /> commonly referred to as just oil and grease (O+G), conventional septic tanks to retain human <br /> wastes, and a large leachfield composed of leachlines and seepage pits. There is a total of three <br /> grease interceptor tanks in series and three conventional septic tanks in series. The exact number <br /> of leacblines and seepage pits is unknown. The only Permit documents obtained from EHD are <br /> located in Appendix E and illustrate a minimal amount of information. <br /> Sampling of effluent from the last septic tank and last grease tank was done with the assistance of <br /> Mr. Jorge Cabrera,the owner of Richard's Pumping&Excavating, Inc. Since he currently pumps <br /> all the tanks about every four months,he is familiar with the tankage orientation. Wastewater <br /> samples were retrieved with a telescoping pole with an attached sample bottle. Effluent flowed <br /> into the attached sample bottle from the "clear zone" of each sampled tank and was then poured <br /> into a one-half liter plastic sample bottle for all of the analyses except O+G. An amber glass <br /> bottle with sulfuric acid preservative was used for the O+G sample. The samples were then taken <br /> to A&L Labs in Modesto for analysis under the attached Chain of Custodies. <br /> Table 3 below illustrates the analytical test results, along with additional data sources for <br /> comparison purposes. The sample retrieved from the last compartment of the last grease <br /> interceptor tank reveals an O+G concentration of 232 mg/L. However, O+G effluent <br /> concentrations leaving the grease tank should be less than 100 mg/L, and then under one-third <br /> (<30 mg/L) of that concentration after it flows into, and through, a conventional septic tank. <br /> In discussions with Mr. Cabrera, it is known by him that the grease tank effluent is not plumbed <br /> Page 4 of 7 <br /> Chesney Consulting <br />
