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