Exhibit Page 25 6. Prevention and mitigation actions: As discussed above, the permit area is more than 800 feet away from any perennial stream, and there are no identified natural wetlands on or within 600 feet of the permit area. However, standard storm water pollution prevention and management actions, including erosion and sedimentation control, will be implemented and maintained. See paragraph 11, below. There is no expectation of either dewatering or process water use /discharge at this site. No net impact on river flow is anticipated. 7. Project water requirements: Initially, water use for extracting and processing aggregates from New Hay Camp Pit will be virtually zero. The current permits for air quality which cover the equipment and actual pit operations (fugitive emissions) are being negotiated but do not require use of watering, water sprays, or addition of moisture, so long as air quality standards (emission tonnages and visible emissions) can be met. These were demonstrated as met in 2001 and 2011 by CDPHE inspection and EPA Method 9 readings. Initially, no washing or processing of water is planned on site, but the landowner and operator may drill a water well in the future to use both for extraction and processing operations, and for post - reclamation activities on -site (including better livestock supply and possible homestead use). Colorado soil management and conservation rules will be implemented to protect surface and ground water quality and improve watershed management. 8. Prohibited actions necessary to protect water systems: None known at this time, other than compliance with best management practices, which forbid the discharge of heavily sediment -laden waters and implementation of spill control and countermeasures actions to prevent discharge of a spilled substance. 9. Wetlands information: US Department of Interior, National Wetlands Inventory Map, Boggy Draw Quadrangle, 1998, identifies no wetlands within the permit area except the stock pond discussed in this report and not in an area to be affected. No impact is anticipated. 10. Floodplain information: There is no portion of the permit area which has been identified in a Flood Insurance Rate Map (FIRM)5 or other document as a floodplain. The terrain is such that it is a professional engineer's opinion that there is no floodplain. 11. Water permitting information Please refer to Exhibit M for additional information. The Applicant does not plan to obtain coverage under a Colorado Discharge Permit System (CDPS) permit for discharge of dewatering flows, and process water, because there is no production of dewatering flows or process wastewater. Although there is no discharge of storm water from disturbed areas, exposed minerals, or work areas (as defined for CDPS permitting), the existing CDPS stormwater permit for McStone Aggregate operations on Hay Camp Mesa will either be modified to include this area (and remove other areas) or a new CDPS permit (or coverage under a general permit) may be obtained. The CDPS permit is the equivalent of an NPDES permit for the state of Colorado. If a water well is drilled on site, a drilling permit and water rights application(s) will be submitted to and approved by CDWR before drilling, in accordance with Colorado water law. Whether permits are required or not, storm water controls ( "best management practices ") as stated in the CDPS storm water general permit for sand and gravel operations will be implemented. (Since there is no discharge proposed from operations, it is technically not necessary to obtain coverage under the general permit, which meets the requirement for an NPDES permit and covers dewatering and process water as well as storm water.) 4 Per conversations with Natural Resource Conservation District personnel. 5 Prepared by Federal Emergency Management Agency, Flood Insurance Administration
