Regular City Council Meeting Monday,May 09, 2011 Page 18 Plat Questions Discussion included private versus public stormwater easements for ponds at the request of the City to avoid future maintenance costs; resolution of fencing mate- rials for an eight foot (8') chain link fence with special slats to make it 100% opa- que and therefore meeting City Code. Conditional Use related to Outdoor Storage Discussion included types of gases stored and distributed, with most used for medical uses; general conditions applied and detailed in the staff report for the outdoor storage of those cylinders; and how to monitor and restrict types of gases stored in Roseville to avoid any gases such as ammonia being stored on site. Applicant Representative, Mike Cavalier, VP of Operations Mr. Cavalier reviewed the typical gases stored and distributed by their company to hospitals and other medical users; advising that, while the company occasional- ly dealt with ammonia, in general their firm attempted not to carry any toxic or corrosive gases at their facilities; but rather shipped them directly from their sup- plier to the customer to avoid that storage. Mr. Cavalier advised that their storage of such gases required additional MPCA requirements, while direct shipping from point of manufacture to point of use negated those additional requirements. Councilmember McGehee questioned if AirGas would object to an additional condition clarifying that hazardous types of gases would not be stored at the Roseville facility. While not currently having any customers using those types of gases, Mr. Cavali- er clarified that there were sometimes government agencies requesting their firm to store ammonia; however,he didn't anticipate the need to bring such requests to staff for approval each time that request was made; and sought clarification on what gases could not be stored. Mr. Cavalier advised that any quantities of cer- tain gases needed to be reported to the MPCA as well as the local Fire Depart- ment for their awareness in case of emergency or if they were required to access the site; and that that information went through a review board when such chemi- cals were on site, as well as the company's own emergency response teams, to address any customer and/or employee exposure to those gases, via a contracted agency, above and beyond any legal or legislative requirements. Mr. Cavalier noted that it was imperative that the local Fire Department be aware of the flam- mable gases on site, including oxygen cylinders. Mayor Roe questioned if AirGas could accept a condition on the CUP that for the time being, AirGas did not store any toxic or corrosive gases on site; and if so de- sired in the future, that they return for additional approval.
