(h)Maximum application rate.

(1)Soil loading standards. The maximum application rate shall be calculated by the appropriate Conservation Division District Office using the following soil loading standards. (Soil loading standards are based upon standards set forth in "Diagnosis and Improvement of Saline and Alkaline Soils," U.S. Agriculture Handbook 60. Pub. U.S. Salinity Laboratory, Riverdale, California, 1954. "Critical Concentrations for Irrigation Water Supplies," Water Quality Criteria, 1972 Ecological Research Series, EPA R2-73033, March, 1973).

(A) Total Soluble Salts - 6,000 lbs/acre (less TSS in soil).

(B) Oil and Grease - 500 lbs/acre.

(2)Determination of most limiting parameter. The maximum application rate shall be restricted by the most limiting parameter. It may require more than one application to achieve the maximum application rate while avoiding runoff. The appropriate Conservation Division District Office shall indicate on the permit what the maximum application rate shall be after making the following calculations:

PROCEDURE FOR CALCULATING APPLICATION RATE OF TOTAL SOLUBLE SALTS (TSS)
	_____ppm TSS in soil1 × 2 = _____lbs/ac TSS in soil 6000 lbs/ac TSS - _______lbs/ac TSS in soil = Maximum TSS (lbs/ac) to applied Maximum TSS (lbs/ac_____÷(_____ppm TSS in water1×.000001) = Maximum lbs/ac of water to be applied_____ Maximum lbs/ac_____÷_____lbs/bbl2 = Maximum bbls/ac_______
PROCEDURE FOR CALCULATING APPLICATION RATE OF OIL AND GREASE
	500 lbs/ac÷(_____ppm in water×.000001) = Maximum lbs/ac of water to be applied______ Maximum lbs/ac_____÷_____lbs/bbl2 = Maximum bbls/ac_______.
1 Electrical Conductivity (EC expressed in micromhos/cm) may be used to estimate TSS: EC × 0.64 - ppm TSS.
2 Based on documented weight of composite sample.

(i)Conditions of permit. Any discharge of produced water that is done under this Section shall be subject to the following conditions or stipulations of the permit.

(1)Presence of representative. A representative of the operator shall be on the discharge site at all times that water is being applied.
