Re: Great Falls and Billings Montana Carbon Monoxide Limited Maintenance Plan Alternative Monitoring Strategy



### Jl..-1 Dear Mr. Martin: ".,.­ 

### Montana is submitting revisions to the State Implementation Plan. This submission contains the alternative monitoring strategy for Carbon Monoxide (CO) as allowed underthe recently updated Great Falls and Billings CO Limited Maintenance Plans (LMP). As you are aware, ambient levels of CO in Montana and nationwide have decreased precipitously, mostly due to federal tailpipe standards and vehicle fleet turnover. Accordingly, the amount of state and local resources necessary to continually confirm trace levels ofCO in the affected LMP areas no longerjustifies the exhaustive and resource intensive use ofgaseous CO analyzers for such purposes.

Montana is interested in ensuring that the affected LMP areas maintain compliance with the national ambient air quality standards for CO despite decreasing federal grant support. To that end, Montana, in close coordination with EPA Region 8 staff, developed and proposes to use the alternative CO monitoring methodology described in the enclosure

## State of Montana Alternative CO Monitoring Strategy Billings and Great Falls CO Maintenance Areas

Alternative CO Monitoring Method

Montanaproposesrevisions to the existing carbon monoxide (CO) Limited Maintenance Plans (LMPs) to adopt alternative CO monitoring methods which do not utilize atraditional gaseous analyzer for determining compliance with the National Ambient Air Quality Standards (NAAQS) for CO in the CO maintenance areas ofBillings and Great Falls. As discussed in the Billings and Great FallsLMPs (submitted to EPA 7/13/2011), these areas have monitored consistently low levels ofCO for over a decade. Most notably, none ofthese areas registered a design value (2nd 

### max concentration) greaterthan 33%ofthe current CO NAAQS from 2006to 2009. Forthis reason, and because there are no foreseen changesthat would increase these monitor values, the Department believesuse ofan alternative methodology otherthan gaseous monitoring would be appropriate to monitor maintenance ofthe CONAAQS for these areas. Montana also believes such a method would notcompromise data collectionfor the NAAQS and will continue to meetthe requirements of40 CFRPart 58, Appendix D.

The alternative CO monitoring method will include an annual review ofthe traffic volumes in each ofthe CO maintenance areas using the data from the Montana Departmentof Transportation (MDT) permanent automatic traffic recorders (ATR) in Billings and Great Falls.

The MontanaDepartmentofEnvironmental Quality (Department) will comparethe latest rolling 3-year monthly average ofthe average daily traffic (ADT) volumes during the traditional high CO concentration season ofNovemberthrough February against the baseline ADT average for those months established by the ATRdata collected during 2008-2010.


### Contingency Plan

Ifthe ADT in a CO maintenance area increasesby greater than 25%when comparingthe most recent, consecutive rolling 3-yearperiod to the baseline 2008-2010 period, then the Department will reinstitute, for that maintenance area, gaseous monitoring at the 2008-20

### I0 monitoring location or at a site expected to read greater CO than that site. The monitoring will be conducted the following winter during the Novemberto Februaryperiod and the results evaluatedto determine ifthe levels ofCO emissions in the area appearto be rising commensuratewith the increase in ADT. Ifthe monitored 2nd 

### maximum value for the Novemberto Februaryperiod has not increased from the baseline mean by an equal orgreaterrate at which ADThas increased, and the monitorvalues remain at orbelow 50%ofthe CONAAQS (2nd 

### max concentration**~.5** ppm currently), the monitormay again be removed and the ADTcounts resumed. Thisprocess will be repeated each time the ADT increases by a factor of25%(e.g. 50%, 75%) above the baseline 2008-2010 period, and the same analysis will be conducted to determine ifthe monitors

can again be removed.

Ifthe percent increase is not greaterthan 25%, then the ambient CO concentrations will be presumed to have remained relatively unchanged.

### AnnualADT comparisonAnalysis

The baseline traffic volume levels for Billings and Great Falls were established using the following data sets:



### Month-Year Billings (#A-050) GreatFalls (#A-033) January 2008 32,778 34,123 Februarv 2008 35463 36855 November 2008 35,832 35675 December2008 32042 33,584 January 2009 33,256 33820 Februarv 2009 35695 36102 November 2009 37,121 37110 December2009 33,905 34,742 January 2010 32,340 34,371 Februarv 2010 34317 36,576 November2010 33885 34,164 December2010 34,317 34,691 

### Averaee 34,246 35,151

The baseline traffic volumes forthe 2008 to 2010 time period, by community, are as follows:

• Billings 34,246

• GreatFalls 35,151

For example, in early 2012, using the ATRdata from 2011, new rolling averages will be calculated for the 2009 to 2011 time period for eachcommunity. Thatnew rolling average for 2009-2011 will be compared to the baseline 2008-2010 average for eachcommunity. The ADT data review process will be repeated each year during the annual monitoring review and the new rolling 3-yearaverage will be compared to the baseline average from 2008-2010.
