b. Land application shall not occur during periods of precipitation, when the soil is frozen, or while the soil is saturated. Wastewater must be stored in the surface impoundments from which it is drawn until the soil is capable of receiving the water without persistent flooding or surface runoff. Clarifier filter cake shall be stored in a manner that will prevent contamination of stormwater.

g. Filter cake may be distributed to facility employees for reuse in accordance with the provisions of the facility’s Residuals Disposition Plan (RDP), which was approved June 10, 2010, and is incorporated as a provision of this permit. A copy of the approved plan shall be kept on-site and made available upon request.

Low volume waste sources include, but are not limited to wastewaters from wet scrubber air pollution control systems, ion exchange water treatment system, water treatment evaporator blowdown, laboratory and sampling streams, boiler blowdown, floor drains, cooling tower basin cleaning wastes, and recirculating house service water systems. Sanitary and air conditioning wastes are not included.

3. The term “free available chlorine/oxidants” shall mean the value obtained using the amperometric titration method for free available chlorine described in “Standard Methods for the Examination of Water and Wastewater, page 112 (13th edition).

4. The terms “total residual chlorine/” and “total residual oxidants” mean the value obtained using the amperometric method for total residual chlorine described in 40 CFR Part 136.
