Additional Sampling Plan of King II Roof, Coal & Floor (PR-1 O) <br /> King II Roof, Coal & Floor Sampling & Analysis <br /> With the addition of private and BLM surface owned parcels added to the permit <br /> application package by Permit Revision PR-10, additional samples, upon CDRMS <br /> approval, will be collected from existing drill cores or from within the current <br /> workings of the King II mine. <br /> Analysis of King II refuse will be accomplished by obtaining roof 8v floor samples of <br /> retained core drilling cores, as well as roof, coal 8v floor samples that may be collected <br /> from active workings at the King II mine. As per "Guidelines for the Collection of <br /> Baseline Water Quality and Overburden Geochemistry Data", as posted on the <br /> CDRMS website, roof 8v floor samples will be collected as composite samples from <br /> strata approximately 5 feet overlying and 5 feet underlying the coal seam, or at site <br /> specific intervals determined to be most likely to be mined and transported to the <br /> refuse pile at King I, a sample of the coal seam, and samples of interburden, partings, <br /> splits, etc. Where possible, these samples will be collected at intervals of <br /> approximately 1 hole per square mile. <br /> Attached King II Appendix 4(8A) Map 3, shows the locations of existing and proposed <br /> roof, coal and floor samples which have been collected and analyzed, or are proposed <br /> to be collected and analyzed. Samples will be analyzed as detailed in the attached <br /> table and text entitled "Proposed Chemical Parameters 8v Methods of Analysis". <br /> Samples labelled RCF #1 thru #3 were chosen to take advantage of locations which <br /> are legally and physically accessible within the King II mine. RCF #4 is an available <br /> drill core which was collected in 2015. Additional proposed samples will be collected <br /> from various available drill cores located as near as possible to the parcels added to <br /> the permit application package by PR-10. <br /> Sample Collection & Analysis <br /> The above samples will be collected by GCC Energy personnel under the direction <br /> and supervision of Resource Hydrogeologic Services, Inc., and transported, under <br /> normal chain-of-custody to a laboratory with the necessary qualifications to analyze <br /> the material. <br /> Results of this sampling and analysis results will be compiled in a report and <br /> included in the King II permit documents as a supplement to Appendix 4(8A) entitled <br /> Appendix 4(8A-1). <br /> CC Energy, LLC King II Mine <br /> Section 2.04.6 <br /> Page 8A June 12, 2020 (PR-10) <br />
