Status of U.S. EPA's (Environmental Protection Agency's) Sludge Incinerator Regulations

摘要

The report describes a potential regulatory approach that the U.S. EPA could use for controlling sewage sludge incinerators. The approach utilizes a most exposed individual risk assessment to ensure that sludge incineration air emissions will not cause an unacceptable health risk. An incinerator facility can demonstrate compliance using a three-tiered system which proceeds from a simple worst case calculation to a more resource intensive site-specific demonstration. A key part of the tiering system is development of an accurate and reliable emissions data base for U.S. sludge incinerators which can be used to develop reasonable worst case emission control factors. The results of testing to date are discussed in the paper.
