"CJ' City of Iowa City MEMORANDUM Date: July 16, 1992 To: Planning & Zoning Commission From: Robert Mlklo, Associate Planner Re: General Industrial Zone (1-1) Amendment to Allow Grain Milling and Processing as a Provisional Use General Mills, Inc. has requested that the City consider an amendment to Section 36-27, General indusiriai Zone (i-i) oi ihe iowa City Zoning Ordinance to permit grain milling and processing as a provisional use (see attached letter submitted by Charles Mullen on behalf of General Mills). The company Is considering establishing a food processing facility in the Business Development Industrial Park (BDI), an area which Is zoned General Industrial (1-1). The Zoning Ordinance currently states that manufacturing; processing and packaging of food and kindred products (except grain milling and processing, stockyards and slaughter houses) are permitted uses In the 1-1 zone. Staff believes that at the time the Zoning Ordinance was written, grain milling and processing was Intentionally excluded from the 1-1 zone, due to concerns regarding dust and the potential for the release of obnoxious odors sometimes associated with wet grain milling. Staff has prepared an amendment to the Zoning Ordinance that would allow certain types of grain milling and processing provided that these concerns are adequately addressed. To address concerns regarding obnoxious odor, the amendment would not allow wet grain milling. To address concerns regarding the release of dust and particulates, the proposed zoning amendment contains a provision requiring that all processing occur within enclosed buildings; the transfer of raw materials be conducted within completely enclosed buildings or by pneumatic tubes, or by sealed containers; and that, when an Application and Permit to Install or Alter Equipment or Control Equipment, Is required by the Iowa Department of Natural Resources (IDNR), which enforces state air quality regulations pertaining to grain milling and processing, such a permit must be obtained prior to the Issuance of a certificate of occupancy. Staff believes that, with these provisions, the concerns regarding dust, particulates and odors associated with grain milling can be controlled to the extent that such an operation would be compatible with other uses allowed in the 1-1 zone, and its Impacts on surrounding land uses, If any, should be no greater than other Industries currently permitted In the 1-1 zone. /fJ tl .IIo'II!Ol'lII_--:"'- t_ . u.

In general, grain milling is the process of separating a piece of grain into its component parts. The two most common forms of grain milling are dry grain milling and wet (corn) grain milling. Dry grain milling separates a piece of grain into various physical components by cracking or grinding the grain. The separated pieces can be equal in size or can be separated by different sizes or weight. For instance dry corn milling can consist of separating a kernel of corn into various physical components Ii.e. the yellow shell, the germ, the'brewer's grit, and/or the corn mill). Wet (corn) grain milling also is a process of separating a piece of grain into parts, however, wet grain milling separates a piece of grain into what are the basic components that constitute the grain (i.e. oils, starches, proteins, and other constituent parts). For instance, to fractionate a kernel of corn into its constituent parts, the corn is soaked in a concentration of water and sulfur dioxide. In general, (the exact process depends on the product being produced) this mixture is ground into a slurry. A centrifuge mechanism is then used to separate the corn into its constituent parts, What environmental Impacts ore associated with the dry groin milling process? Grain milling and processing operations have the potential of emitting particulates and dust into the air. Grain milling and processing operations are required to meet the Iowa Department of Natural Resources (IDNR) particulato emissions requirements associated with grain handling and processing. To meet these emissions regulations, a grain milling and processing operation may need to incorporate a filtering component into its operation. ~ i I I I , I ! j l ; , .L. 1 L_ I " j , " \ ~ U I i , , I I ...._l, i. - -".-r- ---~---- '-, I , I I , , Grain milling and processing can also generate what is called fugitive dust. Fugitive dust refers to the dust generated by the handling, transporting, or storing of a material, in this instance grain. Fugitive dust is the dust other than that generated by the manufacturing and processing component of the grain milling and processing operation. The most common fugitive dust associated with grain milling and processing is the dust associated with the transporting and unloading of grain by truck. Measures can and should be taken to mitigate the degree of fugitive dust emitted into the air. In general, the dry grain milling process creates no or insignificant amounts of toxic air emissions. (Wet grain milling, however, is moderately toxic as a result of the use of sulfur dioxide in the milling process and must meet state air emission regulations regarding sulfur compounds.) However, if energy is created on site for the dry grain milling operation, the process of creating this energy (typically boilers I wouid potentially create toxic emissions which are regulated by the state. Creating energy on-site is not unique to grain milling and processing but can also be a part of other manufacturing operations, The dry grain milling process also generates a level of odor. (Wet grain milling generates a far greater odor than dry grain milling as a result of the sulfur used in the process.) However, the odor generated by food processing which uses milled grain is more significant than the odor generated by dry grain milling. Food processing is already a permitted use in the General Industrial, 1-1, Zone. In addition to air quality considerations, wastewater considerations also exist. A dry milling operation can generate a waste load with significant levels of BOO (Biochemical Oxygen Demand). (Wet milling operations produce an even greater amount of effluent with extremely high levels of BOD). In Iowa City, an industry is granted a three year permit to send effluent at specific BOD and suspended solids levels to the municipal wastewater facility. If an industry would like to operate its facility above these levels, the industry would need to provide an on.site pretreatment wastewater facility to reduce the BOD and suspended solids level before the effluent is sent to the municipal wastewater treatment facility. Anyon-site wastewater pretreatment facility must operate under state regulations, How are grain milling and processing operations regulated for air quality? Any grain milling and processing facility that has the potential of emitting a specific level of particulates into the air is required to file and receive approval of an "Application and Permit to Install or Alter Equipment or Control Equipment" from the Iowa Department of Natural Resources (IDNR). This permit must be granted prior to the installation and construction of such equipment, Once the permit is granted, construction of equipment and operation of the facility may begin. Once an operation of significant size is functional, the operation must be inspected by an independent testing firm to demonstrate that the operation is functioning properly. After that inspection, the regional office of the IDNR regularly inspects the facility. The size of the facility and the number of emission points determines the frequency of the inspections. Generally, the inspections are annual or when a compiaint has been received by the IDNR. nl\p&zgroin,nvnt) I~fs ~.....-_--...- ,.._...,_.._..........~___~ J ....__...-- -.- '-_...~.2 -. i , I i , !
