NCEC - Technical Revision -2- June 13, 1988 <br />• <br />Chemical Parameters (Cont. <br />SAR <br />Sulfate <br />Alkalinity <br />TDS <br />Conductivity (lab) <br />pH (lab) <br />Nitrate . <br />• <br />• <br />During rock tunnel development, the same sites will be monitored monthly for <br />the field parameters listed and quarterly for the chemical parameters listed. <br />Although there may be some confusion about the requirements for the surface <br />water site (CR-2), the permit (Stipulation 3 C) states that this site will be <br />monitored quarterly for the field parameters only. <br />3.0 MONITORING PERFORMANCE <br />According to the 1987 Hydrologic Report prepared by NCEC, all required <br />monitoring was performed, except for the following: <br />CR-2' 2 quarters <br />1-SK-3H 1 quarter <br />2-SK-3H 2 quarters <br />SK-3.75 4 quarters <br />The missed data from the SK-3H completions and SK-3.75 was the result of <br />apparent equipment failure and vandalism, respectively. In addition, access <br />to SK-3.75 has proven to be difficult, except under completely dry conditions. <br />The data missed from CR-2 was the result of oversight by relatively <br />inexperienced NCEC personnel. <br />4.0 PROPOSED MODIFICATION TO THE NCEC MONITORING SYSTEM <br />After reviewing the groundwater and surface water data collected to date <br />within the context of the proposed mine operation, it is apparent that certain <br />stations are not contributing to the intended operational monitoring for the <br />site. <br />New Castle Energy Corporation <br />
