U.S. D.O.I. (Edward Mazzullo)\nApplieability\nFROM: Chris Schimp (owner of Grayson Hill Farms)\n01-0025\nRE: Respectfully request a letter verifing that a Federal exemption is not needed to\ntransport methane gas under 2.1 Division with activated carbon that has been determined\nnot be classified in Division 42.\nGrayson Hill Farms produces electrical power from coal mine methane gas which is sold\non the power grid to local utilities and captures the waste heat from the generators to grow\nHydroponic produce along with fish in speciality designed greenhouses. Chris Schimp a\nMining Engineer has a lot of experience with methane gas and through this experience has\na Patent on a system that can transport methane gas very economically by truck. The State\nof Illinois has awarded Grayson Hill Farms with a Grant to put this system in operation.\nGrayson Hill Farms contracted the scientist from University of Illinois for the carbon\nselection for the transportation system. The carbon selected is from Waterlink/Barnebey\nSutcliffe Corporation and has been determined not to be liable to spontaneous combustion\naccording to IATA Dangerous Goods Regulations and according to the 49 CFR Ch.I, +\nDOT Research and Special Programs Administration. Please find the enclosed test results.\nThe transportation system will involve a propane tanker filled with the carbon which will\nabsorb the methane thus increasing the volume of methane that can he transported in the\ntanker. The pressure will not exceed the rated pressure of the vessel which is 250 psi and\nmeet the necessary safety regulation. The carbon will stay in the tank and will last as long\nas the system is in operation. The methane will desabsorb from the carbon when the\npressure is released from the tanker during unloading.\nA letter verifing that a Federal exemption is not needed is part of the Grant project in\nputting the transportation system together.\n2/6/01\nThank You\nChirschip\nThinks\nJOAN","truncated":false,"body_characters":4116}
