No liquid sludge shall be surface applied within a 100-foot buffer zone of any water course or surface drainage area. 22. Surface applied sludge will be plowed or disced in immediately after application on lands with no cover crop established. 23. All areas with no existing cover crop shall be seeded with a fast growing crop immediately after the first application of liquid sludge to prevent erosion of soil and migration of nutrients from the soil. 24.

The six (6) existing monitor wells shall continue to be sampled every March, July and November for those parameters described above. 1f TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. if the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. The analytical methods used for TOX must be capable of detecting the total of all halogenated organic compounds present at a concentration of 5.0 parts per billion (ppb) or greater. In the event that a TOX concentration of 5.0 ppb,or greater is detected, any individual halogenated organic compound(s) present at a concentration at or above the method detection limit (MDL) must be identified and quantified utilizing EPA methods 601, 602, 604 and 611.
