Yeary\nTruGreen - ChemLawn\nTechnical Center\n135 Winter Road\nDelaware, OH 43015\nDear Mr. Yeary:\nThis responds to your petition for rulemaking (P-1400) requesting that the criteria for Materials of\nTrade (MOTs) be expanded to allow up to 1880 L (500 gallons) of a diluted mixture, not to exceed\n2% concentration of a Class 9 material under the Hazardous Materials Regulations (HMR;\n49 CFR Parts 171-180). In accordance with 49 CFR 106.33(c), your petition is denied.\nThe reasons for this denial are detailed below.\nThe provision authorizing the transportation of up to 400 gallons of a diluted mixture, not exceeding 2%\nconcentration of a Class 9 material as a MOT, was added as a result of a rulemaking action under\nDocket HM-200 - Hazardous Materials in Intrastate Commerce. RSPA did not initially propose\nmaterials of trade exceptions for any bulk quantity of a material. Commenters to the supplemental\nnotice of proposed rulemaking expressed concern that while a small container filled with a concentrated\nhazardous material may meet the criteria for a MOT, when the same amount of material was\ntransported in an aqueous solution in a larger packaging, it would no longer qualify for the exception.\nAs a result of these comments, RSPA agreed with the commenters and authorized a dilute mixture of a\nClass 9 material (up to 2 percent concentration) in a packaging having a capacity of 400 gallons or less\nto be transported as a MOT.\nThe 400-gallon limit accommodated small business practices in place at the time of the rulemaking. It\nlimits the amount of a technically pure hazardous material contained in a bulk packaging to the same\nquantity as is authorized in a non-bulk packaging. An example is chlorpyrifos, a pesticide, which has a\nreportable quantity of one pound. As a concentrate, it would qualify as a material of trade in an eight-\ngallon container. However, due to its one-pound reportable quantity, when diluted with water in a\n400-gallon capacity cargo tank or portable tank to the 1 or 2 percent concentration in which the\nproduct is normally applied, the tank contains a reportable quantity and is therefore a Class 9\nhazardous material. You may transport quantities or concentrations of hazardous materials greater than\nthose adopted under Docket HM-200, however, such shipments are fully subject to the HMR.\n\n<<<PAGE 2>>>\n\n.5\n-2-\nYou have not provided any justification for expanding the exceptions adopted through rulemaking and\nwe do not believe further relaxation is warranted.\nIf you have any questions, please contact Mr. Delmer Billings, Chief, Standards Development at\n202-366-8553.\nSincerely,\npollardem\nRobert A. McGuire\nAssociate Administrator for\nHazardous Materials Safety\n\n<<<PAGE 3>>>\n\nP-1400\nTRIGREEN • CHEMLANN\nTruGreen-ChemLawn\nTechnical Center\n135 Winter Road\n740-548-7330\nDelaware, OH 43015\nFAX: 740-548-4860\nApril 27, 2000\nOffice of Hazardous Materials Standards\nResearch & Special Programs Administration\nDepartment of Transportation\n400 Seventh Avenue\nWashington, DC 20590-0001\nRe: 49 CFR 173.6\nMaterials of Trade Exceptions\nTo Whom It May Concern:\nTruGreen ChemLawn is a private carrier transporting Class 9 materials\nin support of the business of providing lawn care services. We are currently\noperating approximately 4,000 vehicles with cargo tanks up to 400 gallons capacity.\nIn order to increase efficiencies in use of our vehicles and to reduce\nmileage required to return to base and reload materials, we are planning a new vehicle\nwith a cargo tank capacity of 500 gallons.\nWe are petitioning the Office of Hazardous Materials Standards to revise\n49 CFR 173.6(a)(1)(iii) to change the capacity from 1500 L (400 gallons) to 1880 L\n(500 gallons) for a diluted mixture, not to exceed 2 percent concentration, of\na Class 9 material.\nvery truly yours,\nводла Yoy\nRoger A.
