Henning, PE, CHMM DATE: November• 14, 2013 RE: Cottage Grove Ambient Air Monitoring - First Quarter Second Year Results SEH No. 113702 1.0 Introduction The City of Cottage Grove retained Short Elliott Hendrickson, Inc. (SEH) to conduct ambient air monitoring at a location near the 3M Cottage Grove ("3M") facility. The purpose of the monitoring is to measure annual concentrations of pai�ticulate matter, select metals, and volatile organic compounds (VOC) near the incinerator• operated at the 3M facility. In 2009, 3M applied for an amendment to their air permit which would allow the facility to process non-3M generated wastes in the incinerator; the amended perinit was issued in 2012. SEH conducted one year of monitoring, from October 2010 through September 2011, to determine ainbient air conditions prior to 3M processing non-3M generated wastes. In June 2013, after 3M had begun processing non-3M wastes in the incinerator, SEH began a second year of air monitoring to measure ambient concentrations after this change. The City will determine if monitaring is necessary beyond this two year period. The location of the air monitoring site, as well as the sampling and analytical methods used, are the same for the second year of inonitoring as they were for the first year of monitoring. Siinilar to the first year of monitoring, Pace Analytical of Minneapolis, Minnesota is performing the VOC analysis for the second year of monitoring. However, Pace has subcontracted the metals and particulate matter analyses to Bureau Veritas of Novi, Michigan for the second year of monitoring. Bureau Veritas has attained detection limits for the metals analysis at or below the detection limits attained by Pace in the first year of monitoring. SEH continues to follow a quality assurance and quality control (QA1QC) program to help ensure inonitoring results are accurate and precise. QAlQC procedures include collecting field and method blanks, and periodically splitting sample analyses with the Minnesota Pollution Control Agency (MPCA). These steps provide a check that contaminates are not introduced during the sample collection,l�andling or analytical procedures. Table 1 shows the results of the first seven sampling events along with the minimum and maximum ambient concentrations from the first year of ambient air monitoring at the 3M site. Statewide minimum and maximum concentrations measured by the Minnesota Pollution Control Agency during 2012 are also shown on Table 1. The results fi•om the first year of monitoring are provided to compare the current 3M site monitoring data with the range of concentrations measured at the same site before 3M began processing non-3M generated wastes. A discussion of the results in presented in Section 3.0 of this Technical Memorandum.

SEH used meteorological data collected at the meteorological station located at the 3M Cottage Grove facility and the Minneapolis-St. Paul airpoi�t to populate Table 2. Table 2.

B Source: National Weather Service Weather Forecast Office, Daily Weather Observations for the Twin Cities, MN (http://www.crh.noaa.gov/rppx/Climate/MSPClimate.php) 3.0 Results and Discussion The results presented in this Techiucal Memoranduin are considered preliminary since they represent the first seven of approximately thirty samples that will be collected over the second year of the monitoring program. Care should be taken to not emphasize a single concentration because laboratoiy or other errors can result in outliers that do not reflect actual ambient concentrations. A more relevant assessment is an analysis of longer term trends and a�erages. For the first seven rounds of sampling, the results are generally comparable with concentrations measured during the fiist year of testing. The maj ority of the organic compounds have not been detected in the ambient samples. Seven metals and two organic compounds have been consistently detected at the 3M monitoring station: antimony, clu�omium, copper, iron, lead, manganese, nickel, selenium, methyl ethyl ketone, and toluene. Particulate matter was also detected in each sample. The initial laboratory report for the June 27, 2013 sampling event yielded concentrations of inethyl ethyl ketone and toluene that were higher than the maximum concentrations measured for those compounds during the first year of testing. SEH evaluated the quality control and quality assurance data associated with the sample and laboratory analysis and contacted the analytical laboratoiy. After review of their internal quality data, the laboratory determined the sainple had been influenced by another sample analyzed at the lab. They determined the results of the June 27 sample are invalid. SEH has therefore excluded the June 27 sample results from Table 1.
