The National Biosolids Partnership

The National Biosolids Partnership (NBP) advances environmentally sound biosolids management practices, serves as the information clearinghouse on effective biosolids practices, as well as technical assistance, and offers an EMS-based certification program that requires participating organizations to go beyond regulatory requirements.

Biosolids Management Program

The National Biosolids Partnership (NBP) provides training and support to help biosolids management organizations ensure that their programs are environmentally sound and protective of public health. See FAQs about the NBP’s Biosolids Management Program.

The NBP Biosolids Management Program (BMP) is based on internationally recognized standards for an Environmental Management System/International Organization of Standardization (ISO 14001). With guidance from biosolids professionals, experts, and leading biosolids management organizations, the NBP has created a management program tailored to the priorities and needs of the wastewater profession. It serves as a model for continuous improvement in the areas of environmental performance, regulatory compliance, quality management practices, and relations with interested parties and other stakeholders.  

Organizations that have chosen to become certified by the NBP collectively manage more than 12 percent of the biosolids in the United States. These organizations have documented significant benefits in using the program's tools to reduce operating costs and achieve greater efficiencies while protecting public health and managing residuals in an environmentally beneficial and cost-effective manner. NBP organizations focus on consistently producing a high-quality biosolids product for intended markets/end use options and promoting resource recovery while achieving and maintaining public and regulatory trust and acceptance.

The NBP encourages all biosolids management organizations — small, medium, and large — and whatever biosolids treatment and management option is used to participate in the program. Organizations have the option either to develop an audit-ready program or to pursue certification.

Biosolids Management Program Templates, Examples and Revisable Model

The NBP has new resources available for organizations to help make biosolids management systems easier, faster, and cheaper to create and use. All the new resource documents are designed to be used as a set along with other BMP guidance documents.  

The resources include several parts:

  • Revisable Model.  The biosolids EMS model is essentially a generic EMS with sections left blank for agencies to fill in with their own specific details. It is available as a Word document so it can be revised by agencies. Most of the text is already written - all you have to do is fill in the blanks with information specific to your agency.
  • Example. This is a PDF, and provides a completed version of the Model, so agencies can have an idea of the level of detail and type of information needed.
  • Instructions.  This document is also a PDF. The instructions provide a description and summary of key factors to be considered when completing the Model.

NBP Certified and Recognized Organizations
