,. ., odor levels estimated at the rail cars assume that "activated carbon would be used to control the HzS emissions while the railcars are Ueing heated" (pg. 19 of electronic file). Yet, in the EAW, it states, "Due to the portable nature of the rail cars and the small amount of emissions generated, it is not feasible to control the rail cars as they are being heated" (pg. 29). ]-low is it thal they intend to control odor emission with "activated carbon" at the heating railcars? There is no explanation in the memo. With regard to contradictory information in the MPCA presentation, Table 1 of the technical memorandum indicates the "updated" modeled hourly concentration at the HMA plant is 4.4 ug/m3 and at the tank farnt is 6.9 ug/m3. Yet in slide 9 of the MPCA presentation on July 29, 2010, the maximum hourly concentrations of HzS at both points are expected to be significandy higher (see below). The tank farm itself would likely have concentrations at or ahove 20 ug/m3, and 1 recall Heather, the MPCA represenlaCive presenting this data that evening, indicating that this was the case at the storage tank facility. Again, there is no explanation or even reference made to an operational change that would warrant such reduced estimates.

Prohibited Uses Aside from this, 1 would like to point to specific Roseville zooing ordinances that would prohibit this plant from being built. In the cun-enf und pre-amended (Ord. 1397, 10-11-10) industrial zoning codes, chemicals "involving noxious odors or daoger from fire or explosives" are implicitly prohibited in Table ,1� 1007.015, General Requirements (by ivay of the double-negative we're all familiar �vith). Additionally, "noxious" is defined in Chapter 1002 Rules and Definitions as, "material which is capable of causing injury or malaise to living organisms or is capable of causing detrimental effect upon the health or the psychological, social or economic well-being of human beings." (Ord.275,5-12-59) ODOR There are no state standards for odor. However, even using these poten[ially unreliable figures, we can expect that people working and living in the area wil] experience health, ^ psychological, and/or economic issues, thereby failing to meet Roseville's standards.
