Canter Chemical Solutions 1836 Patricia Avenue Willow Grove, P A 19090 Ref. No. 10-0151 Dear Mr. Canter: This responds to your July 15,2010 letter requesting clarification on the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if you may ship a new windshield washer fluid containing methanol between 25% to 30% by volume, with propylene glycol and/or glycerine at a treat rate between 1 % and 5%, as a consumer commodity, ORM-D with six gallons per hiller packaging instead of the 1.3 gallons authorized in § 173.150. For flammable liquids in Packing Group III and combustible liquids meeting the requirements of a limited quantity and a consumer commodity, § 173.150 authorizes inner packagings not over 5.0 L (1.3 gallons) capacity each, packed in a strong outer packaging. You may not exceed the quantity limits authorized in the HMR. However, to ship larger quantities, you may apply for a special permit under subpart B ofpart 107 ofthe HMR. (See § 107.105) I hope this answers your inquiry. If you need additional assistance, please contact this office. Sin:r~~ Charles E.

Mazzullo Director, Office ofHazardous Materials Standards US DOTPHMSA Office ofHazardous Materials Standards ATTN: PHH-10 East Building 1200 New Jersey Avenue SE Washington, DC 20590-0001 Dear Mr. Mazzullo: I am writing on behalf ofmy client who is developing a new consumer, windshield washer fluid product that contains methanol at a level between 25% and 30% by volume. We are also including propylene glycol and/or glycerine at a treat rate between I % and 5%. We would like to ship this consumer product by ground within the US and claim ORM-D status. We would also like to classify the product as "Flammable Liquids, n.o.S. (methanol), UN 1993 ill and use inner packaging that is sized at 23.3 liters ( 6 gallons). We know that according to 49 CFR 173.150 inner packaging cannot be over 5.0 liters (1.3 gallons) to claim ORM-D status. We are asking for an exemption for larger packaging because we can provide additional benefits from a sustainability perspective. Due to the usage rate, ifwe can use the 6 gallon packaging, we estimate a reduction in the amount ofplastic and paper being used by 474,000 lbs and a reduction in the amount of trucking used by 59,000 truck miles. This will reduce air pollution and also lead to an estimated fuel savings of9,833 gallons.. We are requesting a letter ofinterpretation from you to indicate ifwe can use 6 gallon packaging and still claim ORM-D status Ifyou have any questions, please do not hesitate to contact me at (215) 659-8206. Thank you for your prompt attention to this matter. <<>> Sincerely, Dulth Cat, Neil M.
