Network Operation

The HCN and meteorological monitoring network is operated in accordance with the Gold 

Quarry and Twin Creeks Hydrogen Cyanide (HCN) Fence Line Monitoring Plan. The Gold 

Quarry HCN1 monitor is sited south and east of the current meteorological station site at 

570,684 meters east, 4,513,327 meters north, using the NAD83 Datum, UTM Zone 11N. The 

Twin Creeks HCN2 monitor is placed at the location using the NAD83 Datum, UTM Zone 

11N, at 489,225 meters east, 4,568,333 meters north. Refer to the site map in the front of the 

report for specific location information. Both systems collect HCN samples on a 1-in-3 day 

schedule and began operation on December 21, 2009. The systems were powered off 

following shut-down audits on February 24, 2010. Wind direction was out 11 degrees East at 

Gold Quarry and 13 degrees East at Twin Creeks at the shut-down audit. All data was 

adjusted for the time of operation for both sites.

Data Recovery

Sampler data recovery was 100% the period of operation. 

For more specific information, refer to the sampler summaries in Appendix A. 

Data recovery rates for the HCN samplers are summarized as follows: 

Sampler Data Recovery (%) 

Sampler HCN1 HCN2 

12/21/09-2/1/10 100 100 

Meteorological data recovery was 100% for temperature, barometric pressure, and relative 

humidity at both sites. Due to icing, wind speed, wind direction and sigma-theta was 98.5% at 

HCN1 and 99.5% at HCN2.
