In your letter <br />dated August 20, 1992, eo Anne Ihlenfelde, your respond eo our notice o! several <br />• total suspended solids (TSS) violations at: chs above referenced facility. You <br />also request relocatlon of the sampling point for outfall 004. <br />Aa I explained, if documentation is provided co aubatanciac• chat the discharges <br />ver• precipitation-caused and chat they were not vichisr the control of the <br />permitcsa, they can request •xetaption from the TSS limicaclona. A deoonacsacion <br />chat the discharges ver• not within the control of the peraitce• would be if the <br />volume exceeded the design volume of the ponds, providi:~b ch• ponds had been <br />routinely cleaned out to provide the appropriate sediment rcorage capacity (see <br />Burden of Proof Requirements on page 6 of the newest permfL)• My understanding <br />is that you.vill b• writing a letter to request an •xemvciort and provide the <br />required documentation. . <br />Regarding the sampling point for outfall 004, I do not fires chat ehls point has <br />been defined Pos a specific physical point in the permit •~~ any of the prevloua <br />or current rationales. In that ease, the general definition of an outfall <br />applisa. This definition ia: after final treatment and prior co entering State <br />waters. In the case of a pond discharging to a river or stress or ocher <br />drainage, the sampling point is ac the outfall of the pond +nd prior to entering <br />the immediate receiving raur. No specific amendment co •he permit is required <br />for you to adjw a the sampling point as Long as is conforms ~lth this definition. <br />• <br />
