Each of the 10 evaluated records contained all of the information indicated above with the following exceptions: • 5/18/2015 (This was the first record employing CCC's new revised blasting record form): Record included the distance to the nearest dwelling but omitted the direction. Direction could be discerned from other locational information provided but should be indicated on the record. Form asks for "direction to nearest structure" so this was a minor omission likely due to the use of a new / revised form. Delay detonator type was not clear. The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. One blaster -in -charge should be listed by name, license number, and signature. • 5/14/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 5/11/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 5/7/2015: The listed blaster -in -charge name and license number differed from the blaster - in -charge signature. • 5/6/2015: The listed blaster -in -charge name and license number differed from the blaster - in -charge signature. • 5/4/2015: Did not list the delay detonator type (delay periods were listed). The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 4/30/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 4/27/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 4/23/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. • 4/21/2015: The listed blaster -in -charge name and license number differed from the blaster -in -charge signature. CCC had recently revised its blasting record form when we began this record review. One record (5/18/2015) utilized this new form. Due to our findings regarding the delay detonator type and blaster -in -charge identification noted above, we worked with Chip Brown to alter the new form. Mr. Brown added lines to the form to indicate Blaster Leadman (lead person in the field during blast activities) name and license number as well as the overall Blaster -in -Charge name, license number, and signature. He also added language to clearly indicate delay detonator type on the same line as delay times used. When identifying the type of material blasted, CCC indicates whether it was overburden or coal and labels the appropriate strata, e.g. Overburden G7. Many other coal mine operators will label overburden type specifically such as sandstone, siltstone, shale, etc. This practice is beneficial in the event a particular blast requires computer modeling to re-create, for instance if a nearby landowner alleged that a blast damaged their property. While this would be more protective of the mine operator, it is not an explicit programmatic requirement. CCC employs a computer program that identifies the maximum number of holes that will 4 I p a a
