PERMIT#:M-2011-013 <br /> INSPECTOR'S INITIALS:LJW <br /> INSPECTION DATE:May 25,2016 <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 /> 1.) A description of how the spills were cleaned up containing at a minimum -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 farming, 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 letter. All information outlined above and documentation <br /> demonstrating compliance must be received by the Division no later than August 12,2016. <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 /> 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 /> 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 <br /> Page 3 of 12 <br />
