PERMIT #: M-2011-013 <br />INSPECTOR’S INITIALS: LJW <br />INSPECTION DATE: May 25, 2016 <br /> <br /> <br />Page 3 of 12 <br />3.1.13 of the Rules for the Extraction of Construction Materials, The mine operator shall notify the office of a <br />spill of any toxic or hazardous substance, including spills of petroleum products that occurs within the mined <br />land permit area. The operator shall IMMEDIATELY remediate ALL areas that have been effected by spills of <br />engine oil, hydraulic fluid or any other hazardous materials on site and submit a final report to the Division <br />containing at least the following information; <br /> <br />1.) A description of how the spills were cleaned up containing at a minimu m - the appropriate maps, <br />volumes removed, sample locations, analytical data, and photo documentation. <br />2.) Evidence in the form of a receipt that the contaminated soil was disposed of by an approved <br />method (such as sent to an approved landfill, land f arming, recycling center, etc.) <br />The operator shall complete the remediation and submit the required documentation to the Division’s Denver <br />office within 60 days of the date of this let ter. All information outlined above and documentation <br />demonstrating compliance must be received by the Division no later than August 12, 2016. <br /> <br />In the same area of the spills are located two above ground storage tanks for diesel and unleaded gasoline. <br />Along with the fuel storage tanks are numerous containers of engine oil, hydraulic fluids and other hazardous <br />materials. The containers are of various sizes ranging from 5 gallon buckets to 55 gallon drums and 250 gallon <br />cubic containers. Photos Nine though Ten show some of the various containers lacking secondary <br />containment. Photo Eleven shows the above ground storage containers but the secondary containment <br />appeared to be compromised with evidence of spills escaping containment. None of the containers were <br />stored in any form of proper secondary containment. ALL storage tanks, petroleum and any hazardous <br />materials on site for any period of time shall have appropriate secondary containment. The site will also have <br />to comply with all applicable Federal and State Spill Prevention and Control Countermeasure requirements. All <br />secondary containment structures shall consist of an impermeable containment which could contain all <br />contents of the tanks and various containers (when full) plus 10% of the total capacity. The operator shall <br />supply photo documentation that ALL fuel or hazardous materials containers are stored properly - including <br />applicable secondary containment structures within 60 days of the date of this letter. All documentation <br />demonstrating compliance must be received by the Division no later than August 12, 2016. <br /> <br />Another issue that is being cited as a problem is the presence of excessive trash and debris located on site. <br />Collections of empty 5 gallon buckets, scrap metal, used tires, broken down equipment and vehicles were all <br />observed within the permitted area. Also noted was a large pile of broken and unserviceable wood pallets <br />that are not stored in an orderly fashion and need to be either removed or organized. Photos Twelve and <br />Thirteen show examples of the various trash and debris on site. The operator shall submit a written notice to <br />the Division with photo documentation, that the trash and debris has been removed from the site or <br />organized in such a manner that controls unsightliness or deleterious effects of such refuse pursuant to C.R.S. <br />34-32.5-116(4)(e) within 60 days of the date of this letter. Please note that if documentation of the cleanup <br />activities is not received by the division by the corrective action date, the task shall be included in the <br />reclamation cost estimate. ALL documentation demonstrating compliance must be received by the Division <br />no later than August 12, 2016. <br /> <br />Most of the site demonstrated positive drainage and no erosional issues are noted with the exception of one <br />area. Located at the south east corner of the site was a large erosional feature with significant rilling, shown <br />in Photo Fourteen, as well as mineral deposition from evaporated storm waters. The operator shall <br />immediately repair the areas suffering erosion and install some form or temporary storm water control such <br />as silt fence, straw waddles or a containment berm to prevent off-site damage. The operator shall submit
