EPA evaluated the risks remaining after fully implementing the 2003 National Emission Standards for Hazardous Air Pollutants (NESHAP) for Site Remediation and determined that risks from this source category are acceptable. The agency is amending the NESHAP with a lower leak threshold for valves and pumps as a cost-effective technology improvement. EPA is also clarifying that the standards are applicable during periods of startup, shutdown and malfunction, and requiring electronic reporting of performance test results.
