| 99-33033 | Standards for the Use or Disposal of Sewage Sludge | Proposed Rule | The Environmental Protection Agency (EPA) is proposing to amend management standards for sewage sludge by adding a numeric concentration limit for dioxin and dioxin-like compounds (``dioxins'') in sewage sludge that is applied to the land, and monitoring, record keeping and reporting requirements for dioxins in sewage sludge that is land applied. Today's action also presents the results of risk assessments for dioxins in sewage sludge that is applied to the land, placed in surface disposal units, or incinerated. Based on these risk assessments, the Agency is not proposing additional numeric standards or management practice requirements for dioxins in sewage sludge that is placed in surface disposal units or incinerated. EPA is proposing a standard for dioxins in sewage sludge that is applied to the land in order to protect public health and the environment from unreasonable risks of exposure to dioxins. The Agency's risk assessment for land application of sewage sludge estimates that sewage sludge with concentrations of dioxins above the proposed limit may present an unreasonable cancer risk to specific highly exposed individuals. The purpose of this standard would be to prohibit land application of sewage sludge containing concentrations of dioxins above the limit, and thereby protect the health of highly exposed individuals as well as the health of the general population. We are also proposing to exclude from the proposed numeric limit and monitoring requirements treatment works with a flow rate equal to or less than one million gallons per day and certain sludge-only entities that receive sewage sludge for further processing prior to land application. This exclusion is based on the relatively small amount of sewage sludge that is prepared by these facilities and entities and, therefore, the low probability that land application of these materials could significantly increase risk from dioxins to human health or the environment. Finally, we are proposing technical amendments to the frequency of monitoring requirements. These amendments are intended to clarify but, with one exception, not alter the monitoring schedule in the existing sludge rule. The one exception would require preparers of material derived from sewage sludge to determine the appropriate monitoring schedule based on quantity of material derived rather than quantity of sewage sludge received for processing. | 1999-12-23 | 1999 | 12 | https://www.federalregister.gov/documents/1999/12/23/99-33033/standards-for-the-use-or-disposal-of-sewage-sludge | https://www.govinfo.gov/content/pkg/FR-1999-12-23/pdf/99-33033.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is proposing to amend management standards for sewage sludge by adding a numeric concentration limit for dioxin and dioxin-like compounds (``dioxins'') in sewage sludge that is applied to the land, and... |
