Domingue i~e~ <br />RE: Flatiron's Request for Sma11 Area Exemption for Bourg Coal Mine <br />Loadout <br />As the estimated disturbed area is only to be approximately 25,000 sq. <br />ft. (about half an acre) and the fact that the entire area receives less <br />than 9.9 inches of annual precipitation, it is my opinion that a sma11 <br />area exemption is warranted. <br />However, the information provided is insufficient L-o evaIuate the effec- <br />tiveness of the alternative sediment control. The area should be field <br />surveyed and a berm provided on all downslope sides to prevent off-site <br />contamination. A drawing of the area should be provided with one foot <br />contour intezvais on a scale of 1:6000 or larger and the proposed remedy <br />should be detailed on t-he map. <br />/mt <br />
