CITY COUNCIL <br />AGENDA ITEM 6B <br />STAFF ORIGINATOR: Michael Grochala, Community Development Director <br />MEETING DATE: June 12, 2023 <br />TOPIC: Consider 2nd Reading of Ordinance No. 02-23, Amending Chapter <br />405 Related to Bulk Deicing Material Storage <br />VOTE REQUIRED: 3/5 <br />INTRODUCTION <br />Staff is requesting City Council approval to amend City Code Chapter 405 to establish minimum <br />requirements for the storage of deicing material. <br />BACKGROUND <br />Section 18.6 of the City’s General Permit for Municipal Separate Storm Sewer System (MS4) <br />requires that the City adopt a regulatory mechanism (Ordinance) that requires proper salt <br />storage at commercial, institutional, and non-NPDES Permitted industrial facilities. At a <br />minimum the ordinance must require the following: <br />a. Designated salt storage areas must be covered or indoors; <br />b.Designated salt storage areas must be located on an impervious surface; and <br />c.Implementation of practices to reduce exposure when transferring material in <br />designated salt storage areas (e.g., sweeping, diversions, and/containment). <br />Deicers used to reduce ice and snow on roads, parking lots, and sidewalks often include salt, <br />which contains chloride. Chloride is easily transmitted into lakes, streams, and groundwater. <br />This has the potential to impact drinking water supplies, as well as the health of freshwater fish <br />and other aquatic life. Once in the water, there is no easy way to remove it. <br />The draft ordinance establishes minimum requirements for the safe storage of deicer materials. <br />The requirements are applicable to all commercial, institutional and industrial properties in the <br />City. Typically, these are uses that have large parking areas and routinely use deicers as part of <br />their snow removal procedures. The threshold of 5 tons equates to approximately one dump <br />truck load of material. Staff is not aware of any facilities, other than public works, that has this <br />amount of deicer stored. Staff contacted one local construction company that had previously <br />provided winter snow removal services. They indicated they no longer provide those services <br />and do not stockpile salt on the property. <br />The City Council approved the 1st Reading of Ordinance No. 02-23 on May 22, 2023 <br />RECOMMENDATION <br />Staff is recommending approval of the 2nd Reading of Ordinance No. 02-23.
