Propsed changes to paragraph 11 are below.  The changes provide consistency will EPA and other guidelines and make Table 1 more user friendly.

11. Maximum hydraulic loading rates for using TL-2 and TL-3 effluent are found in Table 1 and are to be used as follows:

a. The designer is responsible for reducing loading rates according to the features and properties of the soils in the soil treatment area;

b. Adherence to the maximum sizing criteria herein does not assure or guarantee that other performance requirements of this chapter, including effluent dispersal or ground water quality, will be met. It is the designer's responsibility to ensure that the proposed design is adequate to achieve all performance requirements of this chapter;

c. Hydraulic loading rates shall be incrementally reduced from the TL-2 values in Table 1 when a treatment unit or system is not designed to achieve TL-2 or TL-3. In such cases, the designer shall, for monitoring purposes, specify the effluent quality of the treatment unit. If the specified BOD₅ exceeds 90 mg/l, the designer shall use loading rates for septic tank effluent;

e. Trench bottom hydraulic loading rates for gravity dosed systems shall not exceed the hydraulic loading rates for TL-2 effluent found in Table 1; and

f. Area hydraulic loading rates for drip dispersal, spray irrigation, pads and mounds shall shall not exceed the hydraulic loading rates for TL-2 effluent found in Table 1.
