What is a Biosolids Environmental Management System?
A Biosolids Environmental Management System (EMS) is a program developed by the National Biosolids Partnership (NBP) to improve the quality of biosolids management programs nationwide and to promote public acceptance of biosolids use and disposal practices. In 2002, the City of Los Angeles implemented a Biosolids EMS to meet one of its program goals that was adopted in the Biosolids Policy by the Mayor and City Council in 2000. The biosolids EMS is a management tool utilized by the City to document regulatory compliance requirements and best management practices for biosolids, and to gain public confidence and acceptance in its biosolids beneficial use program.
Biosolids are the nutrient–rich organic byproducts resulting from wastewater treatment. Biosolids are not raw human waste and do not include ash from incinerators, grit and screenings collected during preliminary treatment of wastewater, industrial residues, municipal solid waste, or hazardous waste. Biosolids can take several forms, including a liquid, a rich moist soil, a dried pellet, or compost. Biosolids, when used according to regulations, are safe and can be used as a soil amendment, a fertilizer, as an ingredient in compost, or as an energy source.
The City is committed to managing its biosolids in an environmentally sound, socially acceptable, and cost-effective manner. We are constantly reviewing the program and incorporating continual improvements. Recently the City completed an audit of their biosolids EMS Program. The re-verification audit was performed on September 23-27 by DEKRA, an independent audit firm. The auditors verified that the City’s biosolids program meets the requirements of National Biosolids Partnership (NBP) Biosolids Management Program (BMP) and recommended continued certification in the NBP BMP at the Platinum Level status.
