A land application facility that is not an exempt facility or subject to the registration provisions of section 361-2.3 of this Subpart must obtain a permit and must submit an application, which includes the requirements identified in this section and section 360.16 of this Title. The application must include:
NI = percent inorganic nitrogen = percent ammonia + percent nitrate
NO = percent organic nitrogen = percent total Kjeldahl nitrogen - percent ammonia
NH3 = percent ammonia
NO3 = percent nitrate
N = nitrogen
A = value based on treatment method employed
A values: A = 2 for composted biosolids
A = 4 for anaerobically digested biosolids
A = 6 for aerobically digested, lime stabilized and air dried biosolids
For waste incorporated into the soil:
Pounds available N per dry ton biosolids = (NI x 20) + (NO x A)
For waste surface applied:
Pounds available N per dry ton biosolids = (NH3 x 10) + (NO3 x 20) + (NO x A)
Release of Residual Nitrogen during Biosolids Decomposition in Soil
Years since last biosolids application | AR Values | ||
A=2 | A=4 | A=6 | |
1 | 0.90 | 1.60 | 2.10 |
2 | 0.51 | 0.72 | 0.95 |
AR = Residual Nitrogen Factor
Residual Available N (pounds N per acre) = Original Application Rate (dry ton per acre) x Original NO (percent) x AR
In addition to the requirements outlined in subdivisions 361-2.4(a) -(d) of this section, the application for a permit for a land application facility involving waste other than biosolids must contain the following information:
