Dear Mr. McGrath, 

Please accept this letter as the Montana Department of Environmental Quality's (MTDEQ's) 

certification of its 2014 ambient air monitoring data for the Coburn Road 1-hour and maximum 5-

minute sulfur dioxide parameters and the Libby 1-hour particulate matter with an aerodynamic 

diameter of 2.5 microns or less (PM2.5) parameter as required by Tide 40 Code of Federal 

Regulations Part 58.15. As summarized in the attached reports (AQS AMP600 and AMP450NC), 

MTDEQ's ambient air concentration and quality assurance data for the time period of January 1, 

2014, through December 31, 2014, are completely submitted to AQS. The concentration data are 

accurate to the best of my knowledge, taking into consideration the quality assurance findings. 

Please be advised that MTDEQ will certify the remaining ambient air quality data as part of the 

required annual air monitoring data certification schedule on or before May 1, 2015. 

Digital copies of this letter and the attached reports are being sent to Joshua Rickard at the office of 

EPA . 8.

CERTIFICATION EVALUATION AND CONCURRENCE FLAG MEANINGS 

FLAG MEANING 

M The monitoring organization has revised data from this monitor since the 

most recent certification letter received from the state. 

N 

s 

u 

X 

y 

The certifying agency has submitted the certification letter and required 

summary reports, but the certifying agency and/or EPA has determined 

that issues regarding the quality of the ambient concentration data cannot 

be resolved due to data completeness, the lack of performed quality 

assurance checks or the results of uncertainty statistics shown in the 

AMP255 report or the certification and quality assurance report. 

The certifying agency has submitted the certification letter and required 

summary reports. A value of "S" conveys no Regional assessment regarding 

data quality per se. This flag will remain until the Region provides an "N" or 

"Y" concurrence flag. 

Uncertified. The certifying agency did not submit a required certification 

letter and summary reports for this monitor even though the due date has 

passed, or the state's certification letter specifically did not apply the 

certification to this monitor. 

Certification is not required by 40 CFR 58.15 and no conditions apply to be 

the basis for assigning another flag value 

The certifying agency has submitted a certification letter, and EPA has no 

unresolved reservations about data quality (after reviewing the letter, the 

attached summary reports, the amount of quality assurance data 

submitted to AQS, the quality statistics, and the highest reported 

concentrations) . 

Note: The * indicates that the mean does not 

satisfy summary criteria. Page 5 of 5
