Site Remediation MACT

EPA’s Site Remediation MACT final rule (40 CFR Part 63, subpart GGGGG) was published in the Federal Register on October 8, 2003. It establishes national emission standards for hazardous air pollutants from site remediation activities. The rule covers remediation of contaminated environmental media, such as soils, groundwater or surface water. The affected sources subject to control are: process vents, remediation material management units, and equipment leaks.

The final rule exempts emissions from site remediation when covered under CERCLA or RCRA corrective action programs. The proposal doesn't provide for exemption of cleanups conducted under alternative authority, such as state voluntary programs. Also exempted are cleanups of radioactive mixed waste managed under the Atomic Energy Act or Nuclear Waste Policy Act Authorities and "short duration" cleanups where contamination occurs within seven days prior to remediation.
