Dear Ms. Schilperoort:
This responds to your February 22,2011 letter requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180). In your letter, you indicate that a
company intends to feoffer containers (aerosol cans) manufactured under Special permit
DOT-SP 12995 for disposal or recycling after use. You ask whether such aerosol cans that
have been dented or have missing spray nozzles or caps may be shipped in accordance
with the limited quantities of compressed gas provisions under § 173.306(k), or if they
must be shipped under the terms and conditions of the special permit. Your questions are
paraphrased and answered as follows:
QI. Is the end-user of an aerosol product subject to the terms and conditions of a special
permit granted to the aerosol manufacturer when offering such products for
transportation in commerce?
A I. The answer is yes. In accordance with § 173.22a(b), unless indicated otherwise, a
person may only use a packaging authorized in a special permit subject to the terms
specified therein.
Q2. Special Permit DOT -SP 12995 excepts aerosols manufactured by a certain
company from the hot water bath test prescribed for all aerosols in
§ 173.306(a)(3)(v). Section 173.306(k) excepts aerosols from certain HMR
requirements when transported for recycling or disposal if they meet the conditions
specified in § 173.306(a)(3) (to include the hot water bath test). Is it permissible to
combine the authorization in § 173.306(k) (missing nozzles) with the authorization
in DOT -SP 12995 (hot water bath test) and transport the subject aerosols?
A2. The answer is no. The exceptions for aerosols provided in § 1 73.306(k) require full
compliance with § 173.306(a)(3). Special Permit DOT-SP 12995 excepts aerosols
from the regulation in § 173.306(a)(3)(v) in that each container will be tested as
specified therein in lieu of the required hot water bath test.

Q3. Is it pennissible to rename the containers under the description "Receptacles, small,
containing gas (UN2037)?"
A4. The answer is no. As noted in your letter, the special pennit does not indicate such
an authorized shipping description in Section 6.
Q5. Ifthe answer to the previous two questions is no, what is the appropriate method
for shipping the aerosols?
AS. Under § 107.105, you may apply for your own special pennit that authorizes
shipment ofthe aerosols for recycling or disposal. You may contact our Pennits
and Approvals Division at (202) 366-4535 for more infonnation.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.

SUBJECT: Aerosols Manufactured and Distributed Under DOT Special Pennit Being Offered
For Transportation For Recycling Or Disposal
Dear Mr. Betts:
A company is the end user of aerosol products which would nonnally be shipped as "UN1950,
Aerosols, 2.1" but are being used as materials oftrade in maintenance and other construction
activities. The cans were manufactured and distributed under DOT-SP 12995. The special
pennit provides exemption from 49 CFR 173.306(a)(3)(v) and instead requires that each
container is tested as specified in the special pennit in lieu ofthe required hot water bath test.
After use, the cans are to be shipped for recycling or disposal. Some of the aerosol cans are
partially full, dented, and are missing caps or nozzles .
. A previous letter of interpretation, Ref. No.1 0-0220, states that cans without nozzles are no
longer defined as aerosol cans and should be renamed, for example, "Receptacles, small,
containing gas".
49 CFR 173.306(k) allows cans which conform to 173.306(a)(3), which includes the hot water
bath testing, to be shipped without caps and nozzles but does not provide the instruction to
rename the cans and is silent about special pennit requirements when shipping for recycling or
disposal.

QUESTIONS:
1. 2. 3. 4. Does the USDOT expect the end user of these aerosol products to be aware of and follow'
special pennit requirements when shipping for recycling or disposal?
If the answer to Question 1 is YES, may the aerosol cans be shipped per 173.306(k) AND
the special pennit because it provides equivalent safety even though 173.306(k) is for
cans which confonn to 173.306(a)(3)(v)?
If the answer to Question 2 is YES, should the cans be renamed, "Receptacles, small,
containing gas" as per the above mentioned letter of interpretation or is that not allowed
because the special pennit does not show that name in the special pennit's specific list of
Hazardous Materials Descriptions?
Ifthe answer to Question 2 or Question 3 is NO, what is the appropriate way to ship the
aerosol cans for recycle or disposal?
If you have any questions, please do not hesitate to contact me at (509) 375-9504 or
mcschilperoort@energysolutions.com. Your prompt reply is greatly appreciated.
