Proposed National Emission Standards for Hazardous Air Pollutants: Site Remediation

ACTION

•	On May 2, 2016, the EPA proposed changes to the National Emission Standards for Hazardous
Air Pollutants (NESHAP): Site Remediation. EPA granted reconsideration of these issues on
March 25, 2015. The Site Remediation NESHAP applies to site remediation activities that
involve the removal and treatment of hazardous substances from contaminated media (soil or
groundwater), the contaminated media itself, or the hazardous substances by themselves. It
applies to certain types of site remediation equipment used to clean up hazardous substances
containing organics that potentially could be released to the atmosphere as hazardous air
pollutants (HAP).

•	EPA is proposing to amend the NESHAP to remove the exemption for site remediation activities
conducted under the authority of CERCLA under a RCRA corrective action or other RCRA order.

•	EPA is also proposing to require standalone site remediations, with the potential to emit 10
tons per year of a single HAP or 25 tons per year for a combination of HAPs, to comply with the
rule.

•	The types of businesses most likely to be subject to the rule include, but are not limited to,
organic liquid storage terminals, petroleum refineries, chemical manufacturing facilities,
government facilities such as military operations, and manufacturing facilities using organic
materials.

•	EPA estimates that there are 286 major source facilities currently subject to the rule. The
Agency expects 69 additional major source facilities would become subject to the rule as a
result of the proposed amendments.

•	Based on current data, the EPA does not anticipate hazardous air pollutant (HAP) emission
reductions from these additional facilities. However, the removal of these exemptions ensures
that remediation activities conducted at major source facilities under the authorities of RCRA
and CERCLA will now be subject to the required emission levels for HAP and work practice
standards in the rule.

•	Facilities conducting existing site remediation activities that become newly subject to the Site
Remediation NESHAP as a result of these proposed amendments would be required to comply
with the rule within 18 months from the date the final rule amendments are published in the


-------
Federal Register. New sources (source constructed on or after the date these proposed
amendments are published in the Federal Register for public comments) would be required to
be in compliance on the effective date of final rule amendments or upon startup, whichever is
later.

BACKGROUND

•	On October 8, 2003, the U.S. Environmental Protection Agency finalized the National Emission
Standards for Hazardous Air Pollutants: Site Remediation, 40 CFR Part 63 subpart GGGGG. The
NESHAP established national emissions limitations and work practice standards for HAP emitted
from site remediation activities as well as requirements to demonstrate initial and continuous
compliance with those limitations and standards.

•	On December 8, 2003, the EPA received a petition for reconsideration of two issues in the Site
Remediation NESHAP from the Sierra Club, Blue Ridge Environmental Defense League and
Concerned Citizens for Nuclear Safety. In a March 25, 2015 letter to the petitioners, the EPA
granted reconsideration of the two issues raised in the petition. This proposed rulemaking
addresses the first issue raised in the petition. The second issue in the petition requests that
EPA reconsider amending the rule to include emissions standards for heavy metal HAP.
