Reclamation Plan Inert Filling at Platte Valley Pit by Patrick Broda Dear Ms. Etcheverry: This letter confirms discussions we have had concerning Aggregate Industries,Inc.Platte Valley Pit (AmURS-905)and the importation of inert materials by an outside contractor,Patrick Broth. The result of the conversations is that Aggregate Industries is allowed to import additional inert materials into the Platte Valley Pit according to the stipulations in the permit. Aggregate Industries,Inc. or Patrick Broda do not need any additional permits from Weld County to begin filling operations. Patrick Broda has signed a lease agreement with Aggregate Industries to import inert materials into the Platte Valley Pit. Mr. Broda is aware of your acknowledgement that the permit allows the importation of inert materials as defined in the Regulations pertaining to Solid Waste Sites and Facilities. The attached copy of email I received from you on August 2,2005 describes that acknowledgement The Division of Minerals and Geology will be contacted to confirm the importation of inert materials by Patrick Broda is acceptable to them. Once the Division of Minerals and Geology acknowledges that the importation is allowed,filling of importation of inert materials will begin. It is expected that the importation will begin sometime in early September 2005. If you have any objection to the information in this letter please contact me immediately. Thank you for your assistance and immediate attention to this matter. Yours truly, MOLEN&ASSOCIATES,LLC iatZti Mark A.

The map that you referred to as dated 2/27/04 and titled Platte Valley Pit AMUSR-905, Sheet 2,was not present in the file. However,the resolution and Amended Special Review Permit 905 does require the facility to comply with the requirements of the Division of Mineral and Geology Minded Land Reclamation Permit 112 to conduct surface extraction of construction materials and reclamation of the site. Please also note in accordance with the Regulations pertaining to Solid Waste Sites and Facilities, inert material includes, but is not limited to, earth, sand, gravel rock, concrete which as been in a hardened state for at least sixty days, masonry, asphalt paving fragments,and other inert solids. Additionally, if the site is expecting a change in traffic count,you may want to get a hold of Donald Carroll in Public works to discuss whether if changes in the road agreement will be required.

While you have indicated to Mr. Broda's environmental consultant,Mark Mole;that Weld County does not need any additional permits for this activity,you had requested a copy of the Notice that is required by the State for such activity. A copy of the Notice was sent to you on September 20, 2005. The Division's questions regarding the Notice related to reclamation of the area to receive the backfill and the adequacy of Aggregate Industries' financial warranty for this activity. The enclosed provides a detailed response and is provided for your records in order to keep the County apprised in this matter. Very truly yours, Connie N. Davis Land Resources Assistant Enclosure cc: Mark Molen, Molen&Associates Aggregate Industries-WCR, Inc. -File Aggregate Industries West Central Region, Inc. 1707 Cole Blvd., Suite 100 Golden, CO 80401 Telephone:303-985-1070 An Equal Opportunity Employer A • Certified Mail-Return • Receipt No. 7002 0860 0007 5578 7622 November 7, 2005 AGGREGATE Mr. Tom Schreiner INDUSTRIES Environmental Protection Specialist Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver,CO 80203 Re: Notice of Material to be Imported for Backfill Permit No. M-1989-120, Platte Valley Operation Dear Tom: This letter is in response to questions raised in your letter of September 26,2005 regarding Aggregate Industries' (AI) inert backfill notice dated September 20, 2005. The main concern expressed was whether or not the site is adequately bonded for the proposed activity. The backfill cost estimate referenced in your letter, which addresses backfilling 8066 cubic yards of overburden in a stripped area of Cell 4, is only a portion of the reclamation for which this site is bonded. The Division holds a total reclamation bond for this site in the amount of$754,732. This amount was based upon the Exhibit L calculation prepared by AI and submitted to the Division on December 1, 2003. The calculation for Cell 4 includes a total of 344,232 cubic yards of backfill. Enclosed for your convenience in reviewing this matter are reduced copies of the Exhibit C and Exhibit F drawings. It is M's desire to increase the area to be backfilled in Cell 4 to facilitate a reduction in the final groundwater lake surface proposed in Cells 2 and 4. The import of a potential 603,000 cubic yards of fill material as proposed in the Notice would accommodate the originally proposed and the increased backfill area. The approved permit for Platte Valley already provides for a variance in groundwater lake size in Cells 2 and 4 by as much as 25%, which would be an increase or decrease of 33 acres, without requiring a technical revision. The area to receive the imported fill material is shown on the Exhibit F Reclamation Plan as Phase 4 and will further extend to the north boundary of the groundwater lake area. Backfilled areas will be reclaimed in accordance with Exhibit E of the permit, as follows: The backfill material for this area will be placed and compacted to provide adequate stability for the anticipated future use. The final elevation of the backfilled area will be at least 2 feet Aggregate Industries West Central Region, Inc. 1707 Cole Blvd., Suite 100 Golden, CO 80401 Telephone:303-985-1070 An Equal Opportunity Employer • Mr.Tom Schreiner,Division of Minerals and Geology AGGREGATE November 7,2005 INDUSTRIES Page Two above the estimated maximum local groundwater elevation. In addition,the final backfill elevation in this area will be as near to the existing and surrounding ground elevation as possible(depending on the availability of backfill material). Grading will create relatively flat surfaces appropriate for industrial uses. Any slopes remaining will be reclaimed to a minimum 3H:1 V grade. As final slopes are graded, topsoil will be placed to provide a growing medium for the revegetation cover used to stabilize the area prior to the final land use. (p. 10, Exhibit E, Platte Valley Pit Regular 112 Operation Reclamation Permit Amendment,July, 2003) Clarification regarding reclamation in this area was also provided in responses numbered 13 and 14 of M's December 1, 2003 response to the Division's adequacy review as follows: 13. The reclamation acreage has been clarified on the revised Exhibit F, Reclamation Plan map attached. The groundwater lake to be created in Cells 2 and 4 will be approximately 55 acres in size, or include roup,hly 40 percent of the proposed mined area. Other areas of the mining pits will be backfilled for wetland/upland and industrial uses. If the configuration of the proposed groundwater lake changes, or the size changes by more than 25 percent of the proposed mined area, the applicant will provide a technical revision to the Division with the final groundwater lake size and configuration. 14. The proposed final land use for the Platte Valley site includes future industrial use. However, it is not the intent of the operator to develop industrial use on the site. It is anticipated that these areas will ultimately provide for industrial use, because the areas are zoned industrial by Weld County. The proposed amendment areas zoned for industrial use will be backfilled and graded by the operator. The backfilling will include a cover of at least 6 inches of topsoil. The areas will be revegetated with native grasses to provide stability and minimize erosion until future industrial land uses are applied. In response to your question regarding the maximum amount of imported inert fill material that would be stockpiled,waiting to be pushed into the excavated pit area at any one time, it is anticipated that imported inert materials will be placed on the same day as they are received and not stockpiled. Placement of inert fill will occur in an approximate one acre area at any one time and will continue in such area until the elevation of the backfilled area is in accordance with the permit, as noted above. The original application materials for Amendment 1 indicated that inert materials would be used for backfill, and AI responded to the Division's adequacy comment on this matter in the December 1, 2003 letter as follows: "If applicable, the applicant agrees to provide to the Division with (sic) the appropriate notices and affidavit certifying that the material used for backfill is clean and inert in Mr.Tom Schreiner,Division of Minerals and Geology AGGREGATE November 7,2005 INDUSTRIES Page Three accordance with Rile 3.1.5(9) of the Construction Rules and Regulations." M's September 20, 2005 Notice was submitted to the Division in accordance with that commitment. Thank you again for your time and consideration in this matter.

I have reviewed the information and confered with Trevor Jiricek, Director EHS, about the use of AI's bathroom. It has been determined that the back filling of the mine is part of the reclamation process and the use of AI 's bathroom facilities is appropriate. If you have questions or concerns please let me know.

Due to the lack of import activity,we have not been actively pursuing this matter;however Mr. Patrick Broda,with whom Aggregate Industries has contracted via a lease agreement to perform this phase of site reclamation,would like to proceed with getting the electrical service necessary to this activity and to obtain any County approval necessary to using a portable,temporary shed in conjunction with this activity. As you requested, we are submitting in writing a discussion of activities associated with the import and backfilling operations. I have previously provided to you copies of communications with Weld County which indicate that no additional permits are required by Weld County for the landfill activity,however when Mr.Broda met with you regarding use of a small shed in association with this activity,questions were raised by the Planning Department concerning potential additional impacts. A major concern that you expressed was with regard to Planning Service's understanding that Mr. Broda was proposing an additional access directly onto Highway 85. No new public access is proposed. The inert landfill activity uses the same access as that which is used by Aggregate Industries under the approved AmUSR-905. Enclosed for your reference is a reduced copy of the extraction plan map with the site entrance noted at the north end of the property on Weld County Road 6. Another concern was related to any increase in truck traffic. The import of inert landfill material is not expected to increase truck traffic above the estimations upon which AmUSR-905 received approval. Trucks that are hauling import fill material into the site arc typically those which are already being used in M's operations,in other words,a truck that comes in with a load of import material is then loaded at M's plant for hauling out processed material. We would note that overall traffic counts in this area have not,nor are they expected to,exceed that which was projected under the traffic impact study prepared May 10, 2000 for the combined impacts of Aggregate Industries' Platte Valley site,the Mobile Premix Concrete (LaFarge) Riverhead Operation and Asphalt Paving's Perry Pit. The greatest combined impact Aggregate Industries West Central Region,Inc.

Neither Aggregate Industries nor Asphalt Paving is operating at full capacity, and operations at the LaFarge site have not commenced. We would further note that,while the greatest combined traffic impacts have not,and will likely never be realized,Aggregate Industries constructed improvements including the decel/right turn lane from WCR 6 to southbound SH 85,the accel lane on SH 85 southbound, and the SH 85 northbound decel, left turn lane to westbound WCR 6 without contribution from Asphalt Paving and Lafarge. Aggregate Industries also donated land to Weld County to accommodate widening of the bridge on WCR 6. At the suggestion of Kim Ogle,I met with Char Davis of the Weld County Health Department to discuss any concerns that she may have regarding water and sanitary facilities for employees of the import/backfill activity. Enclosed is a copy of a letter addressed to Char in which I have requested that she respond to you regarding her acceptance of our proposal that such employees will share in the use of AI's existing facilities. The remaining issue is with regard to the use of a 10' x 16' shed in association with the import of inert fill material. Al and Broda acknowledge that a building permit may be necessary for this temporary structure and commit to obtaining the appropriate permits from the Building Department if required. We appreciate your time and consideration in reviewing these responses. If you have additional questions or require additional information, please contact me at(970)336-6526.

Char Davis Weld County Department of Public Health and Environment 1555 N. 17i°Avenue A GG REGATT Greeley,CO 80631 INDUSTRIES Re: AmUSR905—Platte Valley Operation—Broda Landfill Facilities Dear Char: Several months ago I met with you to discuss activities related to import and backfilling of inert fill at Aggregate Industries' Platte Valley sand and gravel mining operation under the above-referenced Use by Special Review permit. The import/backfill activity is in accordance with the approved uses for the site. AI has contracted out this reclamation phase of its activities under a lease agreement with Patrick Broda. When Mr. Broda met with the Planning Department regarding use of a small shed in association with this activity, some questions were raised which we are attempting to address. The issue requiring your input was with regard to the availability of water and sanitary facilities for employees associated with the landfill activity. You advised that a portable toilet would not be acceptable,but that you would recommend either a vaulted system or shared facilities with Al. At the time of our meeting, however,you thought that there may be a requirement that shared facilities would have to be located within 200-feet,and the distance between the landfill activity and Al's facilities is approximately 1200 feet. Following our meeting you called and advised that the 200-foot rule had been removed when regulations were re-written in 2005. AI proposes to share with Broda its water and sanitation facilities located at 1859 U.S.Highway 85 and permitted under SP-0400207. There are only one or two employees associated with the import/backfill activity,which does not increase the load on M's existing sanitary facilities above its designed capacity. The system was designed for a maximum of 12 employees. Al's base of employees using this facility has remained under that maximum throughout its operations. In fact,Al's employee base at the Platte Valley aggregate operation has decreased due to the removal of extraction activity to an adjacent site. Employees who were associated with the extraction activity are no longer working within Platte Valley operations. I believe that you suggested that we provide you with a copy of an agreement that verifies that Broda employees will have access to Al's facilities;however our lease agreement with Broda was executed two years ago and is not specific on this point. By this letter AI commits to making its facilities available for use by Broda,and a copy of this letter is being provided to Broda for his verification of Al's commitment. If you have any questions or need additional information,please do not hesitate to call me at(970)336- 6526.

The main concern expressed was whether or not the site is adequately bonded for the proposed activity. The backfill cost estimate referenced in your letter, which addresses backfilling 8066 cubic yards of overburden in a stripped area of Cell 4, is only a portion of the reclamation for which this site is bonded. The Division holds a total reclamation bond for this site in the amount of$754,732. This amount was based upon the Exhibit L calculation prepared by AI and submitted to the Division on December 1, 2003. The calculation for Cell 4 includes a total of 344,232 cubic yards of backfill. Enclosed for your convenience in reviewing this matter are reduced copies of the Exhibit C and Exhibit F drawings. It is M's desire to increase the area to be backfilled in Cell 4 to facilitate a reduction in the -final groundwater lake surface proposed in Cells 2 and 4. The import of a potential 603,000 cubic yards of fill material as proposed in the Notice would accommodate the originally proposed and the increased backfill area. The approved permit for Platte Valley already provides for a variance in groundwater lake size in Cells 2 and 4 by as much as 25%, which would be an increase or decrease of 33 acres, without requiring a technical revision. The area to receive the imported fill material is shown on the Exhibit F Reclamation Plan as Phase 4 and will further extend to the north boundary of the groundwater lake area. Backfilled areas will be reclaimed in accordance with Exhibit E of the permit, as follows: The backfill material for this area will be placed and compacted to provide adequate stability for the anticipated future use. The final elevation of the backfilled area will be at least 2 feet Aggregate Industries West Central Region, Inc. 1707 Cole Blvd., Suite 100 Golden, CO 80401 Telephone:303-985-1070 An Equal Opportunity Employer Mr.Tom Schreiner,Division of Minerals and Geology November 7, 2005 AC REE'sTE INDUSTRIES Page Two above the estimated maximum local groundwater elevation. In addition,the final backfill elevation in this area will be as near to the existing and surrounding ground elevation as possible(depending on the availability of backfill material). Grading will create relatively flat surfaces appropriate for industrial uses. Any slopes remaining will be reclaimed to a minimum 3H:1V grade. As final slopes are graded,topsoil will be placed to provide a growing medium for the revegetation cover used to stabilize the area prior to the final land use. (p. 10, Exhibit E, Platte Valley Pit Regular 112 Operation Reclamation Permit Amendment, July, 2003) Clarification regarding reclamation in this area was also provided in responses numbered 13 and 14 of AI's December 1, 2003 response to the Division's adequacy review as follows: 13. The reclamation acreage has been clarified on the revised Exhibit F, Reclamation Plan map attached. The groundwater lake to be created in Cells 2 and 4 will be approximately 55 acres in size, or include roughly 40 percent of the proposed mined area. Other areas of the mining pits will be backfilled for wetland/upland and industrial uses. If the configuration of the proposed groundwater lake changes, or the size changes by more than 25 percent of the proposed mined area, the applicant will provide a technical revision to the Division with the fmal groundwater lake size and configuration. 14. The proposed final land use for the Platte Valley site includes future industrial use. However, it is not the intent of the operator to develop industrial use on the site. It is anticipated that these areas will ultimately provide for industrial use, because the areas are zoned industrial by Weld County. The proposed amendment areas zoned for industrial use will be backfilled and graded by the operator. The backfilling will include a cover of at least 6 inches of topsoil. The areas will be revegetated with native grasses to provide stability and minimize erosion until future industrial land uses are applied. In response to your question regarding the maximum amount of imported inert fill material that would be stockpiled, waiting to be pushed into the excavated pit area at any one time, it is anticipated that imported inert materials will be placed on the same day as they are received and not stockpiled. Placement of inert fill will occur in an approximate one acre area at any one time and will continue in such area until the elevation of the backfilled area is in accordance with the permit, as noted above. The original application materials for Amendment 1 indicated that inert materials would be used for backfill, and Al responded to the Division's adequacy comment on this matter in the December 1, 2003 letter as follows: "If applicable, the applicant agrees to provide to the Division with (sic) the appropriate notices and affidavit certifying that the material used for backfill is clean and inert in • Mr.Tom Schreiner,Division of Minerals and Geology AGGREGATE November 7,2005 INDUSTRIES Page Three accordance with Rile 3.1.5(9) of the Construction Rules and Regulations." Al's September 20, 2005 Notice was submitted to the Division in accordance with that commitment. Thank you again for your time and consideration in this matter.

The backfilled areas will include pastureland (with areas of created wetlands) and land for future industrial use (see the Reclamation Plan Map, Exhibit F). Some of the created wetland areas will provide mitigation for the adjacent Wattenberg Lakes site (Permit Number M2001008), while other areas may be used for wetland banking. The size of the groundwater lakes and backfilled areas will depend upon the availability of backfill materials, but the groundwater lakes will be no greater than 100 acres and no less than 10 acres. As backfilling occurs, the areas within the currently permitted site boundary will generally be backfilled for pastureland/wetlands while the mine cell within the proposed amendment area will be backfilled for future industrial use. The office and shop buildings and concrete batch plant will remain on the site following reclamation. In this area of Weld County, mining, water storage, and industrial businesses are predominant land uses along the State Highway 85 corridor. In addition, the western side of the mine site consists of riparian areas along the South Platte River. Therefore, the combination of proposed post mining uses is compatible with surrounding land uses. The remaining area within the proposed permit boundary will consist of access roads and reclaimed or otherwise undisturbed land. The approximate acreage of each of these areas is: Final Land Use Area (acres) I Backfilled for wetland/upland areas 30II Backfilled for future industrial use 19 Groundwater lake and backfilled for 52 wetland/upland areas Groundwater lake and backfilled for future 32 industrial use Access roads 1 Reclaimed or undisturbed land 56 TOTAL 190 Some roads inside the proposed amendment area and existing permit boundary will remain for accessing and maintaining the wetland mitigation and banking areas and CCWCD wells. Conveyor systems will be removed from the site during final reclamation activities. Roads not necessary for future access and other disturbed areas associated with the conveyor system will be reclaimed with vegetative cover to stabilize the soil and minimize erosion. As mining progresses overburden and rocess fin will becom ed for ac filling o the excavated mine cells. Additional overburden, process_fines and Inert material from the Wattenberg Lakes mine site (Permit Number M2001008) and other sites will also Etcamt—Z5.T.lable fb l arkFlling of the mine cell a Platte Valley Operation DMG 112 Permit Amendment Page 8 Backflled Areas In Phase 1 of the reclamation, mining Cell 1 will be backfilled to create intermixed wetland and upland pastureland as mining progresses. The created wetland areas will provide mitigation for the adjacent Wattenberg Lakes site (Permit Number M2001008) and a source for wetland banking. Created slopes will generally be shallow and flowing, but will be at a minimum 3H:1V. The final elevation of the backfilled area will be determined by estimates of the local groundwater elevation. In general, the mine cell will be backfilled to a height approximately 2 feet above the average groundwater elevation. Although the back₹dled ground elevation may be below the high groundwater elevation in the created wetland areas, backfilled elevations will still be high enough to prevent permanently exposed groundwater. It is anticipated that the majority of the backfill material for Cell 1 will be co cessin�_ facrlrty, but overburden material from the site and the adjacent Wattenberg Lakes site may also be used. For amation during Phase 5, overburden material will be available to backfill mining Cell 5 for industrial use, including the existing concrete batch plant. Additional overburden material will also be available from the adjacent Wattenberg Lakes site. The backfill material for this area will be placed and compacted to provide adequate stability for the anticipated future use. e ma e eva i e ac rl e area will be a east 2 feet above the estimated maximum local groundwater elevation. In addition, the final backfill elevation in this area will be as near to the existing and surrounding ground elevation as possible (depending on the availability of backfill material). Grading will create relatively flat surfaces appropriate for industrial uses. Any slopes remaining will be reclaimed to a minimum 3H:1V grade. As final slopes are graded, topsoil will be placed to provide a growing medium for the vegetation cover used to stabilize the area prior to the final land use. Groundwater Lake and Backfilling During the concurrent reclamation in Phases 2, 3, and 4, the mining cells will be graded to create groundwater lakes. The combined surface area of the groundwater lakes will be no greater than 100 acres. Although reclamation during Phase 2 will create a groundwater lake within Cell 2, Phase 4 of the reclamation will likely create a groundwater lake that combines Cell 2 and Cell 4. During reclamation and creation of the groundwater lakes, areas of Phases 2, 3, and 4 may also be used as sedimentation basins for the on-site processing facility. Reclamation in Phases 2, 3, and 4 will include backfilling, grading, and seeding to create groundwater lakes from the mining pits. As grading and seeding is completed in each phase, the groundwater lakes will be allowed to fill, reducing the extent of disturbed area during the mining operation. However, the final size and extent of the groundwater lakes is not fixed. Although the groundwater lakes will be created and stabilized for final reclamation, they may be partially or completely backfilled to reduce their overall surface area. As overburden and other material becomes available from the site and the adjacent Wattenberg Lakes site, the lakes will be backfilled to create areas for either pastureland with created wetlands (Phases 2 and 3) or future industrial usejPhase 4). Since parts Of Cells 7, 3, and 4 may also be used as sedimentation basins, it is likely that process fines will also compose a portion of the backfill material during Platte Valley Operation DNIG 112 Permit A inendaient Page 9 reclamation Phases 2, 3, and 4. The final surface area of the groundwater lake will not be less than 10 acres. For the backfilled areas in Phases 2 and 3, the final ground surface will contain slopes that are generally shallow and flowing, but will be at a minimum 3H:1V. The final elevation of these backfilled areas will be determined by estimates of the local groundwater elevation. In general, the backfill will be to a height approximately 2 feet above the average groundwater elevation. Although the backfilled ground elevation may be below the high groundwater elevation in the created wetland areas, backfilled elevations will still be high enough to prevent permanently exposed groundwater. Portions of the groundwater lake that are backfilled in Phase 4, including the proposed amendment area, will be backfilled for future industrial use. The backfill material for this area will be placed and compacted to provide adequate stability for the anticipated future use. The final elevation of the backfilled area will be at least 2 feet above the estimated maximum local groundwater elevation. In addition, the final backfill elevation in this area will be as near to the existing and surrounding ground elevation as possible (depending on the availability of backfill material). Grading will create relatively flat surfaces appropriate for industrial uses. Any slopes remaining will be reclaimed to a minimum 3H:1V grade. As final slopes are graded, topsoil will be placed to provide a growing medium for the vegetation cover used to stabilize the area prior to the final land use. As groundwater lake slopes and backfilled areas are graded, topsoil will be used to.provide a growing medium for vegetation. Depending on groundwater elevations, the final surface elevation of the backfilled cell may be below the existing and surrounding ground elevation. Any slopes remaining will be reclaimed to a minimum 3H:1V grade. Reclamation Measures/Materials Handling The mining and backfilling will create the rough topography for the land uses. The backfilling and grading will be done to provide stabilized pastureland and future industrial areas and to minimize erosion. The backfill material will consist of native bedrock claystone, process fines,. overburden, other inert materials, and topsoil. The material will be generated from the Platte Valley Operation, the adjacent Wattenberg Lakes site (Permit Number M2001008) and other sites. There will not be known toxic or hazardous materials in the backfill material. Additionally, it is not likely that acid forming or toxic materials will be encountered during mining. The mining will not leave highwalls on the property. There will be no auger holes, adits, or shafts left on the property. Topsoiling The top two to six inches of soil on the property and within the proposed amendment area is generally classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent reclamation techniques, the topsoil is Platte Valley Operation NAG 112 Permit A mendment Page 10 not expected to remain in stockpiles for more than one to two years. If the stockpile remains more than one growing season, it will be seeded with a fast growing vegetative cover to prevent erosion. All topsoil will be retained on-site to reclaim the backfilled mine cell and other areas disturbed by mining activities. Where required, topsoil will be replaced to a depth of approximately four to six inches. When necessary, stripped topsoil will be stockpiled parallel to potential flood flows to reduce the risk of inhibiting the flow. Throughout the mining and reclamation phases, the amount of topsoil stocicpiled will be limited by continuously using it to cap backfilled areas. Revegetation As mining operations are completed, areas for reclamation will be graded and shaped for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded. If needed, berms will be constructed to divert excess water and dispose of it in a safe and non-erosive manner. Upland Areas. For backfilled or disturbed upland areas, the reclamation plan includes revegetating with appropriate seed mixes to minimize erosion and reestablish natural terrain. The grass mixture below was selected to be long lasting and regenerating. The ground will be fine graded prior to seeding and fertilizers will be applied,according to recommendations from the Soil Conservation Services: Groundwater lake side-slopes below the anticipated water level will not be seeded. Based on the soils in the area, the following upland seed mixture is recommended: Area Cover Application Raters Upland Grass Seed (%) (#PLS/acre) Vaughn Side Oats Grama 30% 1.35#PLS/ac. Grenville Switchgrass 20% 0.5 #PLS/ac Lovington Blue Grama 20% 0.3 #PLS/ac Barton Western Wheatgrass 30% 2.4 #PLS/ac Application rate is for drilling the seed. If seed is to be broadcast, the application rate will be doubled. Upland grass seed will be planted with a drill equipped with depth bands and press wheels. The seeded areas will then be covered with straw mulch at a rate of 2,000 pounds per acre. The straw will be crimped into the soil to control erosion until the grass becomes established. If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before they can go to seed. The areas will be mowed periodically for additional control as needed. Mechanical control will be used as a first priority. Chemical methods will only be used if no other alternative produces acceptable results. Wetland Areas. The replacement wetland areas and areas to be used for future wetland b anking will be planted and seeded with native wetland plants. A detailed revegetation plan for the Platte Valley Operation DMG 112 Permit A mendment Page 11 wetland areas is available in the Clean Water Act Section 404 permit application for the Wattenberg Lakes site (Permit Number M2001008) submitted to the Army Corps of Engineers. Water— General Requirement To minimize the effect on the prevailing hydrologic balance, the operator shall: a. comply with all applicable Colorado water laws, b. comply with all applicable Federal and State water quality laws and regulations, c. comply with all Federal and State requirements for dredge and fill, and d. regrade all sediment and siltation structures after mining is completed unless such structures are to be used for wetlands mitigation. Groundwater— Specific Requirements The operation will not affect groundwater quality on or off the site. The operation will comply with State groundwater quality standards. Due to the absence of sources of potential pollutants, groundwater quality monitoring is not required in this operation. Wildlife The proposed reclamation plan does not propose to create wildlife habitat. All activities will be planned considering the safety and protection of wildlife on the property. Some species may be temporarily displaced by the mining activities, but these species are expected to re-establish with no difficulty after the reclamation has been completed. The creation of the lake and wetlands may create additional opportunities for aquatic birds, mammals, and fish.
