Dea¥ Mr', Karst: <br /> <br />I We have reviewed your permit application for a Model 2500 Shaffer --,.. <br /> aluminum sweating furnace, a DAPI aluminum sweating furnace, .and <br /> : a W.w.sly Pactecon model PC baghouse in Ramsey in Anoka Coun.ty.'_'....:: .:'. <br /> It. is our understanding that the Shaffer furnace will be .. <br />I permanently removed from service and-that the Sly baghouse will <br /> .. be used to control particulate emissions from-the DAPI furnace On - <br /> .. a continuous basis. Based_ion. our~..._review of your'appli'cation, .:the .'- <br />I '" Air Quality. Division staff 'has concluded that the potential to <br /> ... emit from your .facility for each one of the criteria pollutants <br /> . is less 'than 25 tons per year. Under Minnesota Rule 7001.12.10 <br />I Subpart 2.A, your facility is exempted from obtaining an air <br /> .. '~.. emission permit from.the Minnesota Pollution Control Agency. - <br /> <br /> ... Facilities that are exempt from the permit requirement are not; <br />I however, exempt from requirements to comply with air quality <br /> rules. For your type of facility, the particulate matter air' <br /> standards (Minn. Rules 7005.0450-7005.0520), the rules for <br />I fugitive 'emissions (Minn. Rules 7005.0550), the rules for odorous" <br /> emissions (Minn. Rule 7005.0900-7005.0980), and the rules for <br /> visible emissions (Minn. Rule 7005'.1120.) would apply. The rule <br /> for fugitive emissions requires that avoidable amounts of ' <br />I " particulate matter shall not be allowed to become airborne. The <br /> 'rule for odorous emissions states that you cannot operate your <br /> facility in excess of the allowable odor emission limits as <br />I specified in the rule. The rule for visible emissions requires. <br /> the opacity of emissions not to exceed 20 percent opacity. <br /> <br /> If you expand or modify the facility in the future, the basis fol.'-:""' <br />I. permit exemption becomes invalid and you must submit a new <br /> the <br /> ~.-' ' permit application for permit review.
