1. (a) Sewage sludge other than residential septage.

   1. (1) Sewage sludge may not be applied to the land if the concentration of any pollutant in the sewage sludge exceeds the ceiling concentration for the pollutant in Table 1.
   2. (2) If sewage sludge, other than sewage sludge that meets the criteria of § 271.911(b)(1) or (3) (relating to special requirements), is applied to agricultural land, forest, a public contact site or a reclamation site, the cumulative loading rate for each pollutant may not exceed the cumulative pollutant loading rate for the pollutant in Table 2.
   3. (3) If sewage sludge is applied to a lawn or a home garden, the concentration of each pollutant in the sewage sludge may not exceed the concentration for the pollutant in Table 3.
   4. (4) If sewage sludge is sold, given away or otherwise distributed, in a bag or other container for application to the land, the concentration of each pollutant in the sewage sludge may not exceed the concentration for the pollutant in Table 3.

2. (b) Tables.

   1. (1) Ceiling concentrations.
   2. (2) Cumulative pollutant loading rates.
   3. (3) Pollutant concentrations.
   4. (4) Revisions to concentrations or loading rates. A new or revised pollutant concentration or loading rate published in the Federal Register as a modification to 40 CFR 503.13(b) (relating to pollutant limits) is incorporated by reference.

3. (c) Residential septage. The annual application rate for residential septage applied to agricultural land, forest or a reclamation site may not exceed the annual application rate calculated using Equation (1).

   

   Where:

   AAR = Annual Application Rate in gallons per acre per 365-day period.

   N = Amount of nitrogen in pounds per acre (kilograms per hectare) per 365-day period needed by the crop or vegetation grown on the land.
