Reference No. 11-0303
Dear Mr. Gosselin:
This responds to your letter requesting clarification of the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180) applicable to the classification of hazardous materials.
Specifically, you ask how Resin Solution containing Di(4-tert-butylcyclohexyl)
Peroxydicarbonate and Tert-Butyl Peroxybenzoate in a felt/glass constructed liner with a
thin film coating should be classified. Your understanding is that the compound resin
product in a felt/glass constructed liner should be classified as "Resin Solution, UN 1866,
Class 3, PG III."
As specified in§ 173.22 of the HMR, a shipper is responsible for properly classifying,
packaging, marking, and labeling a hazardous material for transportation in commerce. This
Office does not typically perform this function. The hazard class of a material is determined
based on the chemical composition and hazard properties of the material. If your material
meets the definition of any of the hazard classes or is a hazardous substance, a marine
pollutant or a hazardous waste, it is regulated under the HMR. Therefore, if the material you
have described remains in its liquid form, it should continue to be classified as a "Resin
Solution, UN 1866, Class 3, PG III."
I hope this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

RE: Request for FonnaL Letter ofinterpretation
Dear Neil,
I spoke with you yesterday in regards to Cured-In-Place Pipe (CIPP) manufacturer and
interpretation regardinf? tFStnsport requirements. Currently, NASSCO (W\\<w.NASSCO.ORG,
National Association of Sewer .Service Comp!llies) has published an instruction guide for CIPP
applications for their nierlibers(see: Styrene Task Force Report). Included in this guide is a
section for ""TRANSPQgTNflON OF RESIN-SATURATED TUBES" on page 9 and 10. 'TI1e
pdfarticle is attached. ·
Th,e NASSCO suggestions for transporting and a September 14, 2011 response from Mr. Charles
Betts.to Mr. Aaron Carr; Reynolds Inliner; Orleans, IN, Reference No. 11-0171 leads me to
request a "Formal Letter <?flntetpretation" by which full information on the products processed
and tranSported is noted below:and MSDS's attached.

I would like to requestfo:r aformalJetter o~interpretation ofthe above mixture, Resin Solution +
Di(4-tert-butylcy((lohe~yl)cperoxydicarbonate + 'fel;t~Butyl per<>xybenzoate :in a felt/glass
constructed Hnerwith a thiif film e0ati:ng. ·
The coatin.g (or oag~ does not pro\tide a "hermetically sealed" containment. The fumes fi·om the
liner ar~··n:0ticed in a refrigerated· cqritairief .. ··1500 ·ppm st}Tene as measured .with a RAE 2000
organic vapor tp.eter wi~JllO.() E.V. hutbs. The liners stored in the refrigerated tmck were 5 each
of 8"x 6mm.x 450', 40~LB ice bags were placed around and on top of the liners.
A liner of thls size (~'~}{QJ:lltp.}{450'j, takes approximately 1, 13{) LBS. of resin solution, 11.3 LBS
ofDi(4-tert-butylcyc1ohex~l) peroxydicarbonate and 5.7 LBS pftert-Butyl peroxybenzoate. The
styrene. component .in the ''resin S()lution??.·.is typically less than 40% by weight or 452 LBS.
Note: · 5 liners are transported: 5650 Ll3 Resin+ 56.5 LB primary org411ic peroxide+ 28.5LB secondary perox.ide
Could you please confirm our understaqding of the 49 CFR (parts 1 00-185) compounded resin
product as. follows:
.. • Proper Shipping Name: Resin Solution
• UN 186Q'; Class 3, PEI 111
• Hazarft ~ting~.: Hel!ltl1.2, Fl{lmmability 3, Reactivity 2
Note: Reaetfvityrallilgijlcreased Irom 1 to 2
For Hazmat, First Responders and'ContrQUed Product Regulations, a new MSDS for the product
transpot'ted. would make the product in accordance. with hazmat criteria.
It is disturbing that a compound of this tyPe coq.ld }Je classified as a Cla~s 9, UN3077 and be
allowed on passenger or cargo airtfreight as NASSCO and Re,ynolds, Inc suggests.
I appreciate your ~ttentiQn to.:tfrls matter, ifmore information is required, pl~ase contact me
anytime. Thank Youfo'ryoirr assistance,
