|Residual, Biosolids, Sewage Sludge
Residual is generated by both domestic treatment plants (sewage sludge) and industrial treatment plants (industrial residual). Residual is managed in variety of ways, including the development of Marketable Residual Products (often referred to as biosolids) used to fertilize or condition the soil. Examples include pellets, compost, alkaline materials, food processing by-products and water treatment residuals.
Residual is also incinerated in New Jersey and managed in a variety of ways at out-of-state facilities. Beneficial use of residual as a fertilizer or soil conditioner is regulated under a New Jersey Pollutant Discharge Elimination System permit issued by the Bureau of Pretreatment and Residuals and may require site specific approvals, depending upon the nature of the residual. Incineration of residual is regulated under New Jersey's Air Pollution Control Program. While residual managed in other states is regulated by the receiving state, the generator must demonstrate to the Department compliance with the receiving state's law.
The Bureau of Pretreatment and Residuals also oversees the Statewide Sludge Management Plan (a component of the Statewide Solid Waste Management Plan) and reviews and approves long term generator residual management plans. Finally, through the implementation of the Sludge Quality Assurance Regulations, residual generators must test their residual and report the results to the Department on a regular basis. This data is available to assure compliance with the appropriate residual management criteria in much the same way that the surface water program uses effluent data to assure compliance with wastewater discharge requirements.

Historic Sewage Sludge Quality (Updated 08/01/13)
This file charts historic, median, statewide sewage sludge quality for pollutants that are limited for land application. For determining median concentrations, if analytical testing did not yield a pollutant concentration above the minimum detection level, the pollutant concentration is assumed to be the minimum amount of pollutant that could be measured. Equating undetected data points to their minimum detection level is a conservative assumption since it tends to overestimate pollutant concentrations.
Residuals Discharge Monitoring Reports
You may access Discharge Monitoring Report (DMR) data for residual generators through the Department's Open Public Records Act website under NJPDES Permitting. There you will find a number of useful reports including "Residuals (SQAR) DMR Data by NJPDES Number." Further instructions are provided below the link to the report.
If you have any questions email Tim Doutt or call 609-633-3823.
