New EPA Proposal Would Remove CERCLA, RCRA Exemptions from Air Emissions Rules

On May 12, 2016, the EPA proposed a rule (RIN 2060-AN36) which would remove the exemption for site cleanup activities under the hazardous waste statutes from the emissions standards for hazardous air pollutants under the Clean Air Act.  The proposed rule would amend the National Emission Standards for Hazardous Air Pollutants (“NESHAP”), Site Remediation Rule, to include activities taken under CERCLA and RCRA, as well as RCRA corrective actions and orders.

Under the amended rule, the NESHAP permitting requirements would apply to site activities that involve the removal and treatment of hazardous substances from soil or groundwater, the removal of the hazardous substances themselves, as well as to equipment used in the cleanup of hazardous substances that could release the substances into the atmosphere as hazardous air pollutants.  The rule also clarifies that jurisdiction does not depend upon the site remediation activities being co-located with at least one other stationary source already regulated by another NESHAP.

The proposed rule would require standalone site remediations with the potential to emit 10 tons per year of a single hazardous air pollutant or 25 tons per year of any combination of HAPs to comply with the rule.

Comments to the proposed rule, which can be found here are due on June 27 and interested parties may request a public hearing.
