Grain Elevator Permitting Requirements and Documents The Environmental Protection Commission adopted new grain elevator permitting rules on January 15, 2008. The rules will become effective on March 19, 2008. (See link below for copy) The rules modify requirements for certain types of grain elevators and feed mill equipment collocated at certain types of grain elevators. The rules define each type of grain elevator facility and specify for each type of grain elevator the permitting options, emissions calculation methodology, emissions reporting and record keeping, and best management practices for controlling air pollution. A new particulate matter emissions standard for bin vents located affected grain elevators was also established through amendments to subrule 23.4(7). Applicants must use the grain elevator PTE calculation tool to determine their group classification. A link to the calculation tool and user’s manual is included below. Affected owners or operators of grain elevators are required to submit a registration form or applicable permit application by March 31, 2008 for existing equipment. For Group 1 and 2 facilities, as defined in the rule, links to a registration form or a Group 2 permit application can be found below. Permit applications and instructions that can be used for Group 3 or 4 grain elevators, as defined in the rule, can be found at www.iowacleanair.com/prof/const/const.html. Permit applications for unpermitted feed mill equipment must be submitted by March 31, 2008.
