SECTION 252:616-11-3. Operation restrictions

(a)   Uniform application. Land application shall be uniform over each plot (a predetermined portion of the land application site) unless otherwise permitted by the DEQ.

(b)   Prevention of toxicity. Annual land application shall not exceed permit limits set for each constituent and shall not be applied in rates that result in toxicity to site vegetation.

(c)   Soil and vegetation. Land application shall occur on soils which exhibit physical and chemical properties that promote assimilation and treatment of the wastewater or sludge (e.g., infiltration rate, storage capacity, or other properties) and which support vegetation (e.g., native grasses) or in order to prevent erosion of the soil (such as dust suppression). Add minerals and other materials to ensure levels of oxygen, pH, nutrients and moisture as needed to sustain native vegetation.

(d)   Soil profile. The soil profile depth to bedrock shall be three (3) times the depth of incorporation or three (3) feet, whichever is greater unless prior written approval is obtained from the DEQ.
