. n, <br />(Page 2) <br />MIFF ID t OR PAOSPECTIN6 ID 1 MBA-093 <br />INSPECTI011 DATE MI INSPECTOR'S INITIALS SSS <br />OBSERVATIONS <br />This was a routine inspectim of the Hi¢~ Flume Gravel Pit, a permitted 110(2) gravel operation approved to disturb 9.8 acres in the course of mining <br />gravel to a depth of 15 feet. The operator indicated that he believes the gravel rws much deeper than the 15 feet originally permitted and he expressed <br />an interest in revising his permit to allow extraction down to the wderlving sandstone formation which is an additional 15 feet to 25 feet lacer. The <br />operator also expressed an interest in revising his permit bamdary to include an area where gravel was excavated for use on his own property. The flat <br />area where this excavation occurred would be used for topsoil storage. The operator should be aware that these, or any changes, that deviate from the <br />approved mine plan myst be submitted as a Technical Revision td the penit and be approved by the Division before any non-permitted mining activity takes <br />place. Failure to receive Division approval before performing anon-permitted mining activity an the mine site may result in an enforcement action. <br />The operator began mining activity on the site in the 1994 field season. Mining has disturbed only cell one to date. Topsoil has been stored on the <br />southwest corner of the cell as permitted. The rewining cells call for topsoil storage west of the access road which may not be possible due to lack <br />of sufficient area between the road and the west hillside. If the operator must opt for another topsoil storage site, a revision to the permit must be <br />submitted and receive Division approval. Equipment on site consists of a compressor, a grizzly and a scraper trailer. <br />Changes to the Hined Land Reclamation Act, due to the passage of Senate Bil] 91-177 in 1991, included the removal of the SSOlTD.00 bond cap for 110(2) type <br />permits. All mine sites in Colorado are now required to be banded for the actual cost of reclawtion if, in the case of permit revocation and bond <br />forfeiture, the state were to put the reclamation work out far competitive bid. Review and recalculation of the required band for reclamation of this <br />operation will take place over the nett few mmths. A detailed estimate of the recalculated cost, based on the approved mining and reclamation plans and <br />conditions observed during the inspection, will be forthcomi~. <br />In 1987, the U.S. congress amended the Clean Hater Act to expressly include storm water discharges from industrial sites as requiring Clean Hater Act <br />controls. In 1990, EPA issued regulations that require specific industrial activities to obtain permits in order to discharge storm water from their <br />facilities. Active and inactive mining operations where storm water comes into contact with overburden, raw eaterial, intermediate products, byproducts, <br />finished products or waste products located at the mining site are specifically included. The deadline to apply far a storm water permit was October 1, <br />1992. If a stop water penit for this sine has not yet been obtained, the operator must make application for such a permit as soon as possible. If any <br />storm water control structures are regzired to be constructed at the mine as a result of the storm water permitting process, a revision must then be <br />suhitted to this Division to include the operational and reclamation aspects of such structures in the Reclamation Penit. <br />I 6 E Contact Address cc: Tao Gillis, DIE <br />0~ <br />NNE Dale 6 Betty Trenkle p 8L <br />OPERATOR Same p FS <br />STREET 350 Hiah Flume Loav p HN <br />CITY/STATE/ZIP Duranm, Colorado 81301 p HF&RD) (CH) <br />o sE <br />,g Waco (cN) <br />Q OTHER <br />
