Collision Repair Environmental Training
National Emission Standards for Hazardous Air Pollutants
40 CFR Part 63, Subpart HHHHHH
Examination Answer Key
1. This air regulation was developed by which of the following federal agencies?
a. OSHA – Occupational Safety and Health Administration
b. EPA – Environmental Protection Agency
c. BOA – Bureau of Air
d. USDA – United States Department of Agriculture
A:
In Kansas, the Kansas Department of Health and Environment Bureau of Air has
delegation of this regulation, meaning they can perform inspections at shops to check for
compliance with this EPA regulation.
2. This regulation is referred to as which of the following:
a. Paint stripping and miscellaneous surface-coating operations at area sources
b. The “6H” rule
c. The “auto body” rule
d. All of the above
A:
The regulation is officially called, “Paint Stripping and Miscellaneous Surface Coating
Operations at Area Sources” and nicknamed the “6H rule” or “auto body rule.”
3. The national emission standards for hazardous air pollutants (NESHAPs) regulate two
categories of sources that emit air pollution. Which of the following two are they?
a. Area sources
b. Hazardous air pollutant (HAP) sources
c. Major sources
d. The “urban dirty thirty”
A:
Most, if not all, collision repair shops are going to fall in the area source category.
Technically, “area" sources are those that annually emit less than 10 tons of a single hazardous
air pollutant (HAP) or less than 25 tons of a combination of HAPs. Note these can be any
hazardous air pollutants that are on the HAP’s list.

4. Which of the following chemicals in autobody paint is not of concern (or targeted) for this
HAP regulation?
a. Cadmium
d. Lead
b. Chromium
e. Manganese
c. Cobalt
f. Nickel
A:
If a chemical is thought to cause cancer [hexavalent chromium (Cr+6), cadmium, lead,
and nickel], and it is present in the paint in a concentration above 0.1%, than the requirements
of this regulation must be followed. Also, if a chemical is not a carcinogen (trivalent chromium
(Cr+3) and manganese), but it is present in the paint in a concentration above 1.0%, than the
requirements of this reg applies
5. The collision repair shop will need to meet these air regulations if any paint used has one or
more of the targeted HAPs and the paint is applied using which of the following methods?
a. Powder coating
b. Hand-held, non-refillable aerosol containers
c. Spray-apply
d. All of the above
A:
Other applications that are NOT considered spray-applied and therefore not subject to
this rule include the following:
 Use of hand-held device with a cup capacity < or = 3.0 fluid oz (89 cc)
 Non-atomizing technology
 Thermal spray operations using solid metallic or non-metallic materials
6. If spray-applied paint does not contain any of the five targeted metals, then an owner or
operator of a collision repair shop may petition EPA for __ __________ from the 6H rule.
a. A certification
b. A pass
c. An exemption
d. None of the above
A:
A form is available at http://www.sbeap.org/aqrules/page/6h-rule. If EPA grants the
exemption, keep the paperwork on file. Although the rule has some good management practices,
the shop will not be subject to this rule if granted an exemption.
7. Touch-up jobs, using paint containing any of the targeted metals, do not have to follow this
rule if touch up is performed using a hand-held device with a cup capacity less than or equal
to ____ fluid ounces.
a. 1
b. 3
c. 5
d. 7

8. Paint-booth filters must have what percent collection or capture efficiency?
a. 88%
b. 95%
c. 98%
d. 100%
9. This capture efficiency information can be obtained from whom?
a. The filter sales representative
b. The manufacturer
c. Both of the above
d. Neither of the above
10. When painting an entire vehicle, booths and prep stations must have a full roof and how
many walls or side curtains?
a. 1
b. 2
c. 3
d. 4
11. When painting vehicle parts, booths and prep stations must have a full roof and how many
walls or side curtains?
a. 1
b. 2
c. 3
d. 4
12. When painting vehicle parts, booths must be ventilated such that air is drawn in what
direction?
a. Into the booth
b. Away from the booth
c. Across the booth
d. None of the above
A:
Into the booth and through the paint filter.

13. Spray-applied coatings must be applied with which one of the following gun technologies?
a. High volume, low pressure
b. Electrostatic
c. Airless
d. Air-assisted airless
e. Any of the above
A:
Or some other spray technology approved by EPA, that will achieve an equivalent
transfer efficiency as an HVLP gun.
14. The ultimate goal of gun cleaning with regard to the 6H rule is to prevent creating which of
the following?
a. Hazardous waste
b. An atomized mist
c. Wastewater
d. None of the above
A:
The 6H rule is an air regulation, so the concern is minimizing air emissions.
15. Which is an acceptable option for cleaning spray guns?
a. Hand cleaning a disassembled gun
b. Flush gun with solvent, without spraying
c. Use fully enclosed gun washer
d. All of the above
A:

c. The paint supplier that hosted a training
d. The EPA
A:
