Region 8

Biosolids

**NEW**: Propose and Modify NPDES General Permits for Facilities That Generate, Treat, and/or Use/Dispose of Sewage Sludge by Land Application, Landfill and Surface Disposal in EPA Region 8.

The EPA Region 8 biosolids general permit expires January 15, 2015, and no coverage will be granted. In accordance with 40 CFR §503.3, the permitting authority, in this case the EPA, may either issue a permit or rely on direct enforceability of the 40 CFR §503.  Direct enforceability means that no person shall use or dispose of sewage sludge through any practice for which requirements are established in 40 CFR §503 except in accordance with such requirements.

At this time the EPA Region 8 is not issuing facility coverage under the EPA Region 8 Biosolids General Permit. In addition, the Region 8 Biosolids Permit will expire January 15, 2015. Therefore, you are required under the Direct Enforceability provision of 40 CFR §503.3(b) to meet the applicable requirements of the regulation.  Obtain an electronic copy of the 503 regulation here.


What are Biosolids?

Biosolids are, in effect, a slow-release nitrogen fertilizer with low concentrations of other plant nutrients. In addition to significant amounts of nitrogen, biosolids also contain phosphorus, potassium, and essential micronutrients such as zinc and iron. Many western soils are deficient in micronutrients. Biosolids are rich in organic matter that can improve soil quality by improving water holding capacity, soil structure and air and water transport. Proper use of biosolids can ultimately decrease top soil erosion.

When applied at agronomic rates (the rates at which plants require nitrogen during a defined growth period), biosolids provide an economic benefit in addition to their environmental benefits. Colorado State University agronomists have shown continuous application of three dry tons per acre every other year to dryland wheat produces comparable yields, higher protein content, and larger economic returns compared with the use of 50-60 pounds per acre of commercial nitrogen fertilizer.

 

What are the Traditional Practices in this Region?

Before about 25 years ago, the traditional practice in this Region was to landfill or incinerate what was then called sewage sludge. During the past quarter century the practice changed to recycling biosolids as soil amendments. Region 8 recycles 85% of the biosolids generated in the six state Region. Data from 1996 indicated that 90% of the facilities meet the more restrictive Table III requirements (see 40 CFR Part 503).
