APPLICATION FOR LICENSE TO AUTHORIZE NEAR-SURFACE LAND DISPOSAL OF LOW-LEVEL RADIOACTIVE WASTE Appendix 2.3.1: Meteorological and Climatology Data March 16, 2007 2.3.1-5 Revision 12a 1.0 COLLECTION OF METEOROLOGICAL DATA Meteorological data have been collected on the WCS property to meet two primary criteria. First, precipitation and evaporation data have been collected as required for determining a water balance for the proposed Site. Second, air quality data have been collected for analyzing potential releases of airborne radioactivity.

Data were collected from the on-site meteorological station operated by WCS as well as four additional stations in the area for use as a comparative analysis. The data collected by the on-site meteorological station operated by WCS (WCS station) is summarized in conjunction with data collected by the four regional weather stations listed below:

WCS Station, located on the WCS property approximately 1/2 mile southwest of the proposed Site. The WCS station data was collected during the period from January 2000 through December 2005. The WCS Station data is tabulated in Tables 25 through 40 and Figures 8 through 17. WCS station has sensors at both the 2-meter (lower) and 10-meter (upper) height intervals.

Andrews, Texas station located 50 km (31 miles) southeast of the proposed Site. Data averages, unless otherwise noted, are based on available historic records from 1914-2006, using climate summaries updated on November 2, 2006 (WRCC, 2006). Data for this station are included in Tables 1 through 5 and Figure 1.

Midland-Odessa Regional Airport, Texas station located 103 km (64 miles) southeast of the proposed Site. Data averages, unless otherwise noted, are based on available historic records from 1948-2006, using climate summaries updated on November 2, 2006 (WRCC, 2006). Data for this station are provided in Tables 13 through 24 and Figures 2 through 7.

Hobbs, New Mexico station located 32 km (20 miles) northwest of the proposed Site.

Data averages, unless otherwise noted, are based on available historic records from 1914-2006, using climate summaries updated on July 28, 2006 (WRCC, 2006). Data for this station are provided in Tables 6 through 9. While there are two weather stations for Hobbs, NM, the airport station has only limited data for a drier ten-year period. So the other weather station in Hobbs, NM (ID 29-4026), which has a much longer historical record (at least 70 years of recorded data), was included in the climate summaries.

Jal, New Mexico station located 39 km (24 miles) southwest of the proposed Site.

Data averages, unless otherwise noted, are based on available historic records from 1919-2006, using climate summaries updated on July 28, 2006 (WRCC, 2006). Data for station are provided in Tables 10 through 12.

The Andrews, Midland, Hobbs, and Jal stations provide a long-term data set to compare against the 6-year data set collected at the WCS station. The Midland-Odessa station is the closest First-Order station to the proposed Site and is operated by the National Weather Service.

APPLICATION FOR LICENSE TO AUTHORIZE NEAR-SURFACE LAND DISPOSAL OF LOW-LEVEL RADIOACTIVE WASTE Appendix 2.3.1: Meteorological and Climatology Data March 16, 2007 2.3.1-6 Revision 12a 2.0 TEMPERATURE AND HUMIDITY On-site measured air temperatures at 2 meters were consistent with an annual pattern of high summer temperatures and low fall (and winter) temperatures as indicated in Table 25 in this appendix. The highest and lowest temperatures recorded on-site between January of 2000 and December of 2005 was 107.9 degrees F and 3.7 degrees F, respectively. The mean monthly average temperatures on-site ranged from 82.0 degrees F in July to 42.2 degrees F in December.

The lowest and highest relative humidity values recorded are from 30% in April (lower station) to 84% in October (lower station). The average monthly relative humidity ranged from 50% in April (upper station) to 70% in October (lower station). On-site humidity data for the upper and lower stations are summarized in Tables 27 and 28 respectively in this appendix.

Summaries of the historic record of temperature data, including minimums, maximums, and means, for the Andrews, Hobbs, Jal, and Midland meteorological stations are included in Tables 1, 6, 10, and 13 in this appendix.

3.0 PRECIPITATION Precipitation data for the WCS station are presented in Table 26 and Table 26A in this appendix.

The average annual rainfall at the proposed Site from January 2000 through December 2005 is 15.8 inches. The maximum on-site rainfall amount recorded for a 24-hour period is 4.45 inches.

Minimum and maximum monthly rainfall totals recorded for this period were 0.1 and 8.8 inches, respectively. Snow and freezing rain data were not collected at the WCS station.

Summaries of the historic record of rainfall data are presented in Tables 2, 7, 11, and 14 of this appendix for the Andrews, Hobbs, Jal, and Midland meteorological stations. Average annual totals for the respective periods of record were 15.3 inches for Andrews, 16.0 inches for Hobbs, 12.5 inches for Jal, and 14.0 inches for Midland. These tables also present the minimum and maximum monthly totals. The data for all stations clearly demonstrated an annual rainfall in the region of less than 20 inches. The maximum 24-hour maximum rainfall amounts recorded at the four stations were 7.6, 7.5, 5.6, and 4.8 inches for Andrews, Hobbs, Jal, and Midland, respectively. By comparison, the 24-hour, 100-year storm event for the region, as calculated by NOAA, is 6.1 inches (Miller et al., 1973).

Annual snowfall averages were recorded at 3.4, 5.1, 3.5, and 4.1 inches for Andrews, Hobbs, Jal, and Midland, respectively. Summaries of the historic record of snow data, including averages, maximums, and minimums, for the Andrews, Hobbs, Jal, and Midland meteorological stations are included in Tables 3, 8, 12, and 15 in this appendix.

APPLICATION FOR LICENSE TO AUTHORIZE NEAR-SURFACE LAND DISPOSAL OF LOW-LEVEL RADIOACTIVE WASTE Appendix 2.3.1: Meteorological and Climatology Data March 16, 2007 2.3.1-7 Revision 12a 4.0 WIND AND ATMOSPHERIC STABILITY Wind speed and direction data measured at the WCS station at the 2- (lower) and 10-meter height (upper) are presented in Figures 8 through 12 and 13 through 17 in this appendix, respectively. These data were used to develop joint frequency distributions of wind speed and direction. The data are summarized in Tables 29 through 33 and 35 through 39 in this appendix.

Wind direction measured on-site is primarily from the south, south-southeast, and south-southwest, with the greatest percentage from the south. These sectors together account for 28.5 percent of hourly average wind data for the period. The next most frequent wind direction is east-northeast, northeast and east sectors accounting for 17.2%. Average wind speeds varied very little from month to month. The strongest average winds during the monitoring period were from the southerly directions with average wind speeds of 8 to 11.5 mph. The highest one-hour wind speeds occurred during September, blowing from the south-southeast direction. The highest recorded one-hour wind speeds were 32.8 and 43.6 miles per hour at the 2-meter and 10-meter height, respectively.

The Pasquill-Gifford method was used to estimate atmospheric stability at the site using the 2-and 10-meter wind data collected from the WCS station. The joint frequency distributions of wind speed and direction as a function of Pasquill stability class (A-F) are presented in Tables 34 and 40 for the 2-meter and 10-meter stations. Midland-Odessa Station using National Weather Service meteorological data for same joint frequency distributions is presented for the 10-meter height in Table 24. Five years of data (1999 through 2003) from the Midland-Odessa Station were used in comparison to the WCS station data collected between 2000 and 2005.

The most important and potentially adverse condition for atmospheric dispersion, stable (Class F) and low wind speeds 0.4 to 1.3 m/s (1.0 to 3.0 mi/hr) occur 2.2% of the time. The highest occurrences of Pasquill Class F and low wind speeds with respect to wind direction are toward the south. Mixing height limits recorded for Midland reported by Draxler and Heffter, (1981) ranged from 1592 feet in the winter to 2381 feet in the summer, with an annual average of 2014 feet.

5.0 NATURAL HAZARDS AND STORM ACTIVITY Sand or dust storms typically occur in the winter or early spring when rotors (horizontal vortices) generated by strong westerly winds blowing across the region touch the ground. Most episodes of dust prevail for only six hours or less, when visibility is restricted to less than 0.5 mile.

Statistical information is lacking on seasonal distribution intensity and duration of dust storms for the region. Recent data recorded in Lubbock, Texas (110 miles northeast of the site) indicates blowing dust an average of 12 times in the spring and 9 times during the remainder of the year (Bomar, 1995).

Two F2 Class (wind speed from 113 to 157 mph) tornadoes have been recorded in Andrews County, TX from 1880 through 1989 (Grazulis, 1993). According to data reported by NOAA, there has been two F2 Class and eight F1 Class (wind speed from 73 to 112 mph) tornadoes recorded in Andrews County since 1950. The NOAA web search for tornadoes is included as in this appendix.

The mean number of annual thunderstorm days for Hobbs, NM and Midland, TX is 25.5 and 36.4 days, respectively (Weather Disk Association, Inc., 1990; NOAA, 2004). No records are

APPLICATION FOR LICENSE TO AUTHORIZE NEAR-SURFACE LAND DISPOSAL OF LOW-LEVEL RADIOACTIVE WASTE Appendix 2.3.1: Meteorological and Climatology Data March 16, 2007 2.3.1-8 Revision 12a maintained for the frequency of thunderstorms at the proposed Site. However, the actual number of events can be expected to be similar to these regional data.

Information regarding extreme natural events, such as flooding, thunderstorms, high winds, hail, and lightning, are presented in Tables 41 - 43 and Attachments 1 - 4. As previously mentioned, the NOAA web search for tornadoes is included as Attachment 5 in this appendix.
