Area Source NESHAP
Implementation in Iowa
A review of the latest federal air
toxics regulations affecting many
small businesses
Definitions
• NESHAP = National Emission Standards for
Hazardous Air Pollutants
• Found in 40 CFR Part 63
• DNR adoption in 567 IAC Chapter 23
• Area Sources = Facilities or installations
that have the potential to emit less than 10
tons per year of any single hazardous air
pollutant (HAP) or 25 tons per year of any
combination of HAP (not major sources)
Area sources are of concern because although generally
small in size, they are large in number and collectively,
area sources may pose health risks.
Why Area Source NESHAP?
The federal Clean Air Act (CAA) requires EPA to:
• Reduce public’s exposure to HAP, sometimes called “air
toxics,” that are known or suspected to cause cancer or
other serious health effects
• Identify and list at least 30 HAP that pose the greatest
risk in urban areas (EPA identified/listed 33)
• Identify and list area source categories (industries or
operations) that represent 90% of the 33 urban HAP
emissions (EPA’s “urban air toxics strategy”)
• Set standards for the listed area source categories
• Ensure that area sources meet, at a minimum, Generally
Available Control Technology (GACT)
Background
• Pre-2005: 15 NESHAP issued – e.g. Dry
Cleaners, Halogenated Solvent Cleaners,
and Chromium Electroplaters
2006-2007: 10 NESHAP issued – e.g.
Clay & Ceramic Products, Lead Acid
Battery, Wood Preserving and Hospital
EtO Sterilizers
• January 2008-now: 9 NESHAP issued,
so far - More small businesses and
previously unregulated facilities impacted
Overall Challenges
• Estimate 3000-5000 facilities in Iowa could
be impacted by area source NESHAP
• Several NESHAP issued at or near the same
time
• No additional funding from EPA
• Limited staff and resources
• Some facilities may be subject to more than
one NESHAP
Facing the Challenges
NESHAP Implementation Group
▫ Formed in March 2008
▫ Cooperative effort among DNR – Air
Quality Bureau, University of Northern
Iowa – IAEAP, Iowa Department of
Economic Development – Small Business
Liaison, Linn & Polk County Local Air
Programs
▫ Developing outreach strategies
▫ Working with impacted stakeholders
Facing the Challenges
Implementation Approaches
▫ DNR vs. EPA implementation
▫ Developing outreach and compliance
assistance strategies specific to each NESHAP
 Identifying affected facilities
 Presentations & workshops
 Fact sheets & other outreach materials
 Website (for easier access)
 Guides
 Listserv and newsletters
 Streamlined permits & registration forms
Standards for Stationary
Internal Combustion Engines
• One NESHAP & Two New Source
Performance Standards (NSPS) for stationary
Compression Ignition (CI) and Spark Ignition
(SI) engines
• HAP emissions from engines include
formaldehyde & benzene
• All sizes of engines covered (no deminimus
level)
NESHAP does not impact existing engines at
this time
Stationary Internal Combustion
Engines
• Affects owners and operators of stationary
engines manufactured after certain trigger
dates
▫ 2006 for CI engines & 2008 for SI engines
• NESHAP Requirements include:
• Manufacturer certification to meet
emission standards (some exceptions)
• Use of low sulfur fuel
• Non-resettable hour meter
Stationary Internal Combustion
Engines: Challenges?
• Stationary engines are used at many different
types of facilities (no specific industry sector)
• Regulations are lengthy, complex and confusing
• Hundreds if not thousands of new engines will be
installed over the years
• Portable engines – Some are considered to be
“nonroad” and are not subject to NSPS-NESHAP
• EPA has proposed standards for existing engines
that may pose very stringent requirements in the
next few years.
Stationary Internal Combustion
Engines: Addressing Challenges
• Developed engine registration form for
smaller engines
• Working with engine distributors,
municipal utility associations and other
stakeholders
• Developed listserv articles and Frequently
Asked Questions document (on website)
Surface Coating NESHAP:
Subpart 6H
• Sets standards for three source categories to
control HAP emissions from:
▫ Paint stripping (methylene chloride (MeCl))
▫ Surface coating of motor vehicle/mobile
equipment (Target HAP)
▫ Miscellaneous surface coating (Target HAP)
• Applies only if spray apply coatings that
contain the Target HAP: Lead, Manganese
(Mn), Nickel (Ni), Cadmium (Cd) or
Chromium (Cr)
6H NESHAP: Who is Impacted?
• Manufacturers who spray apply coatings
to metal or plastic (wood and other
materials are not covered)
▫ Estimate 100-150 Iowa facilities
• Autobody shops and other mobile
equipment refinishers/manufacturers (e.g.
trailer mfg)
▫ Estimate 1000-2000 Iowa facilities
6H NESHAP: Requirements?
Specific equipment and management
practices required for:
▫ Paint booth exhaust systems
▫ Spray booths/prep stations
▫ Spray guns
▫ Spray gun cleaning operations
▫ Painter training
6H NESHAP: Challenges?
• Many autobody shops need assistance with
NESHAP and other air quality requirements
• HAP-free coatings for autobody operations are
not yet readily available
• Painter training not yet widely available
• All autobody/mobile source operations are
affected, even if Target HAP-free, unless they
request and receive an exemption from the
Administrator (DNR)
6H NESHAP: Addressing Challenges
• Streamlined permitting: DNR revised
permit-by-rule (PBR) to include 6H
questions
• Outreach materials
• UNI-DNR workshops – over 700 attendees
• Partnering with stakeholders on training
and outreach
Metal Fabrication & Finishing
NESHAP: Subpart 6X
• Sets standards for nine source categories
under 12 SIC codes (Standard Industrial
Classification)
▫ Must be more than 50% of the production at the
facility to be an affected source
• Regulates emissions of Lead, Mn, Ni, Cd, and Cr
• Applies to five types of manufacturing activities
at covered facilities
• Applies only to facilities with potential to emit
MFHAP or that use materials that contain
MFHAP
6X NESHAP
• Challenges
▫ Applicability issues with SIC and
determining primary production activity
▫ Standards & management practices are
complex (e.g. welding and painting)
• Addressing the Challenges
▫ Streamlined permitting - PBR
▫ Outreach Materials
Gasoline NESHAP: Subpart 6B
& Subpart 6C
• Sets standards for gasoline source
categories to control benzene emissions:
▫ Bulk gasoline distribution (6B)
▫ Gasoline Dispensing Facilities – GDF (6C)
• Gasoline includes ethanol blends up to
E85
• Oil, diesel and other fuels are not covered
6B NESHAP
• Affects Bulk Gasoline Sources
▫ Gasoline terminals
▫ Pipeline breakout and pumping station
▫ Gasoline bulk plants
• Requirements:
▫ Must use submerged fill
▫ Minimize gasoline vapor releases
▫ Monthly leak inspections
▫ Larger terminals - install emissions control
6B NESHAP: Challenges?
• Most bulk plant owners/operators are
unfamiliar with air quality regulations (most
bulk plants are unpermitted)
• Many bulk plants are located in rural areas,
some are unmanned
• Nearly all bulk plants need a throughput limit
< 20,000 gallons/day to avoid classification as
bulk terminals
• Some bulk plants may not yet have submerged
fill on loading racks
6B NESHAP: Addressing Challenges
• Developing a streamlined permit template for
bulk plants
• UNI developing a compliance calendar
• Working with Petroleum Marketers and
Convenience Stores of Iowa (PMCI) and
Agribusiness Association of Iowa (AAI) on tool
development and roll-out
• Permitting assistance and compliance
workshops scheduled for winter 2010
6C NESHAP
• Affects GDF - Commercial gas stations
(estimate ~3000 facilities) & other
installations
• Requirements
▫ Small GDF: Best management practices
(BMP) for gasoline vapor and spills.
▫ Medium GDF: BMP and submerged fill
▫ Large GDF: BMP, submerged fill, vapor
balance systems (Stage 1) and initial/periodic
vapor testing
6C NESHAP
• Challenges
▫ Implementation at Large GDF
• Addressing the Challenges
▫ Two formal meetings with interested
stakeholders
▫ Working closely with underground storage
tank (UST) interests (DNR, PMCI, consultants
and insurers) to disseminate NESHAP
compliance and inspection information
▫ EPA intends to issue 6C amendments in fall
2009 to clarify definitions and applicability
Plating & Polishing NESHAP:
Subpart 6W
