The Environmental Protection Agency (EPA) has implemented all of the recommendations GAO made in its May 2011 report to improve the Unregulated Contaminant Monitoring Rule (UCMR) program. In that report, GAO recommended that EPA (1) monitor for the full 30 contaminants allowed by statute, (2) monitor for most or all contaminants using a more robust monitoring approach, and (3) select sufficiently...
Chemical Assessments: An Agencywide Strategy May Help EPA Address Unmet Needs for Integrated Risk Information System Assessments
GAO-13-369: Published: May 10, 2013. Publicly Released: Jun 10, 2013.
The Environmental Protection Agency (EPA) has not conducted a recent evaluation of demand for Integrated Risk Information System (IRIS) toxicity assessments with input from users inside and outside EPA. Specifically, EPA issued a needs assessment report in 2003, which estimated that 50 new or updated IRIS toxicity assessments were needed each year to meet users' needs. However, GAO did not find su...
Hazardous Waste: Early Goals Have Been Met in EPA's Corrective Action Program, but Resource and Technical Challenges Will Constrain Future Progress
GAO-11-514: Published: Jul 22, 2011. Publicly Released: Aug 25, 2011.
Years of industrial development generated hazardous waste that, when improperly disposed of, poses risks to human health and the environment. To mitigate these risks, Congress passed the Resource Conservation and Recovery Act of 1976 (RCRA). Subtitle C of RCRA, as amended, requires owners or operators to take corrective actions to clean up contamination at facilities that treat, store, or dispose...
