1. 1. Inspect all biosolids pathogen and vector treatment facilities, transportation vehicles, incinerators that fire sewage sludge, and land application sites to determine compliance with this Article;
2. 2. Inspect and copy records prepared in accordance with this Article; and
3. 3. Sample biosolids quality.

4. 1. The relationship between the annual pollutant loading rate (APLR) for a pollutant and the ABAR is shown in the following equation.

   APLR = C x ABAR x 0.001

   APLR = Annual pollutant loading rate in kilograms of biosolids, per hectare, per 365-day period;

   C = Pollutant concentration in milligrams, per kilogram of total solids (dry-weight basis);

   ABAR = Annual biosolids application rate in metric tons, per hectare, per 365-day period (dry-weight basis); and

   0.001 = A conversion factor.

   metric ton = 1.102 short tons

   hectare = 2.471 acres

5. 2. The ABAR is calculated using the following procedure:

   1. a. Analyze a biosolids sample to determine a concentration for each of the pollutants listed in Table 3 of R18-9-1005; and
   2. b. Using each of the pollutant concentrations from subsection (2)(a) and the APLRs from Table 3 of R18-9-1005, calculate a separate ABAR for each pollutant using the following equation:
   3. c. The ABAR for biosolids is the lowest value calculated in under subsection (2)(b) for any pollutant.

A person subject to this Article shall allow, during reasonable times, a representative of the Department to enter property subject to this Article, to:

Appendix A. Procedures to Determine Annual Biosolids Application Rates
