# Re: Clean Data Showing Attainment of the Lead National Ambient Air Quality Standard for the Logan County Nonattainment Area in the State of Ohio Dear Administrator Hedman: I am pleased to notify you that based upon the most recent 2009 to 2011 lead monitoring data certified in U.S. EPA 's Air Quality System (AQS), the Logan County nonattainment area is now attaining the 2008 lead standard of 0.15 j..Jg/m 3

. 

# In October 2009 Ohio EPA submitted our "2008 Re vised Lead Standard Recommended Designations and Nonattainment Boundaries" recommendation. At that time Ohio recommended that partial areas of Cuyahoga, Fulton and Logan Counties be designated as nonattainment for the lead standard. U.S. EPA approved our recommendation on November 22, 2010 (75 FR 71 033) with an effective date of December 31, 2010. The partial nonattainment boundary for Logan County includes sect ion s 27, 28, 33 and 34 of Lake Township near the Daido facility located in the City of Be ll efontaine (Figure 1)

. In June of 2009, the Da ido facility permanently shut down a ll lead operations and since that time there has been a clear downward trend in lead em iss ion s.

# Figure 1. Logan County Partial Nonattainment Area

The Daido facility historically had four monitors recording lead levels. Monitor 39-091- 0006 was retained as the designated lead monitor for this area as part of the 2010 approved monitoring plan. Prior to 2010, this monitoring site was operated by a contractor through the Daido facility. After the facility shutdown, Ohio EPA took over operation of this monitor. However, during this transition time there is a gap in data for the months of November and December of 2009. Therefore, the 

# 75°/o capture criteria was not met for monitor 39-091-0006 as seen in Table 1 below (AQ S database retrieval is enclosed).

# In accordance with 40 CFR Part 50, Appendix R, less than complete data may continue to be used to determine attainment of the NAAQS upon U.S. EPA approval giving consideration to the circumstances. Attached you will find a data subst itution ana lys is performed by Ohio EPA. Th is ana lys is method is consistent with the method identified in 40 CFR Part 50, Appendix R. Spec ific a lly , Sect ion 4 (c)(ii) suggests when the 75°/o data collection criteria is not met, validating a below- NAAQS level 3-month lead mean can be accomplished by using actual "h igh " values reported for the same site at about the same time of the year lookin g across three or four years. Based on this analysis the following 3-month averages were determined for the periods in Table 1 above where 75°/o data capture wasn't met.

# • Sep-Nov 2009: 0.063 • Oct-Dec 2009: 0.107 • Nov-Jan 2010: 0.095 • Dec-Feb 2010: 0.057 Based on this substitution analysis, the current design value for the 2008 lead standard in this area is 0.11

# ~g/m**.** The two months of missing data occurred during a period of time when Daido had ceased all lead operations while the data used in the substitution method was from a period of time when Daido was still operational. Ohio believes that had the missing data been collected it would not have resulted in a design value that would exceed the standard. Therefore, Ohio is requesting U.S. EPA approve the use of less than complete data for this monitor considering the factors identified above. In summary, we request U.S. E PA to act in a timely manner to make a formal finding that the nonattainment area identified in Figure 1 above is attaining the 2008 lead standard. Ohio E PA plans to follow up this letter with requests for redesignation of this nonattainment area. If you or your staff have any questions or would like additional information, please feel free to contact Jennifer Dines at (614) 644 -3696. Sincerely,

Prior

# to January 2010, this site was operated by a contractor through the Daido facility itself. These two months of missed data collection werethe result of Daido shutting down, the contractor leaving, and Ohio EPA working to resume operation of th is site and establish it as the designated monitor fo r this nonattainment area. Previously, Ohio EPA devel oped an imputation and bootstrapping procedure to substitute missing monitor valu es with statistically valid calculated values. This procedure, however, is dependent on the availability of a more complete data set from a co-located monitor for which a high degree of correlation can be established. In Logan County, only monitor 39-091-0003 had complete data in 2009. However, the correlation between monitoring values recorded atmonitor 39-091-0006 and 39-091-0003, based on a linear regression analysis, was determined to be insufficient (R2

# = 0.0065). Therefore, the imputat ion and bootstrap procedure was not used to substitute missing values. Instead, the highest monthly value for the months of November and December for the 2005 to 2011 time period recorded by monitor 39-091-0006 were selected as replacements for the missing 2009 data . The highest monthly average lead concentration for the month of November, 0.12 μg/m 3 

# , occurred in 2006, and the highest monthly average concentration for the month of December, 0.16 μg/m 3 

# , was observed in 2005. Using these values as replacem ents for the missing data in 2009, a passing value is identified for all 36 consecutive averages in the 2009 to 2011 time period. The values substituted for the missing data in2009 are highly conservative, based on the trend in observed concentrations recorded at site 39-091-0006. Figure 2 shows the time series of monthly average values recorded at site 39-091-0006 from January of 2008 to December of 2011, aswell as a nine-month moving average of this time series.

# Examination of the moving average clearly demonstrates that the monthly average concentrations of lead recorded at this monitor have been declining steadily, and values above 0.100 μg/m 3 

# have not been observed at this m onitor since September of 2008. Also clearly demonstrated is the rapid drop in lead concentrations following the shutdown of Daido Metals in June of 2009. In Figure 3, the time series of observed m onthly average lead concentrations at site 39- 091-0006 are presented, in cluding substituted values for November and December of 2009. 0.000 0.020 0.040 0.060 0.080 0.100 0.120 0.140 0.160

# Figure 2: Monthly average lead concentrations, 2008 to 2011.

# Examination of this data clearly shows thatthe values chosen for substitution are significantly higher than typical values observed at the monitor for all months between 2008 and 2011, and well above 9-month moving average trend. Additionally, values observed at the co-located monitor, 39- 091-0003, were 0.068 and 0.026 for November and December of 2009, respectively. Thus, the chosen substituted values are considered highly conservativeand likely well above the act ual monthly concentration of lead at the monitoring site. However, usin g these substituted values, a passing, valid design value of 0.11 μg/m 3

# was identified for the 2009 to 2011 time period. This analysis method is consistent with the method identified in 40 CFR Part 50, Appendix R. Specifically, Sect ion 4(c)(ii) suggests when the 75% data collection criteria is not met, validating a below-NAAQS level 3-month lead mean can be accomplished by using actual “high” values reported for the same site at about the same time of the year looking across three or four years. 0.000 0.020 0.040 0.060 0.080 0.100 0.120 0.140 0.160 0.180
