Section 391

Section 391.410 Nutrient

Sludge utilization permit

applications must include agronomic calculations which specify the application

rates (dry tons per acre) to be utilized by sludge users. Unless site specific

information on crop yields is available, the applicants must use the average

county crop yields shown in APPENDIX C in conjunction with the fertilizer

requirements specified in APPENDIX B. The applicant must determine whether the

sludge application site is to be used on a short term (<5 years) or long

term (>5 years) period and calculate the necessary nitrogen or phosphorus

agronomic rate. The applicants shall use Sections 391.411, 391.412 and 391.413

for determining the nutrient loading.
