Re-vegetation of the site should contain native and natural seed mixes as identified in a letter dated November 4, 1999, from Steven C. Augerot with the City Parks and Recreation Department. In addition, noxious weeds are anticipated to be a problem and should be eradicated using a combination of techniques. y r �� November 4, 1999 TO: Debbie de Besche FROM: Steven C. Auger , Parks Program Manager SUBJECT: Weld County Camas Mining Project After reviewing the application for amending the Use by Special Review for the Camas Mining Project, I have the following concerns: • There is no comment about how the Poudre River Trail corridor will fit into the finished project. • If at all possible, it would be nice if the proposed water storage ponds could be combined into one large lake that then could be used for recreational purposes. Additionally, if this were possible, or even if they could not be combined, it would be nice if the design was more aesthetically pleasing. • Regarding the revegetation of the site, the grass seed mix containing Sideoats Grama, Switchgrass, Blue Grama, and Wheatgrass would be much preferred over the second mix. I am including a list of mixes the City is currently using in various situations as possible alternatives. The following trees and shrubs do not seem appropriate for this location, Honey Locust, Lilac, and Tartarian Honeysuckle. • In paragraph four of Exhibit E, it states that, "Weeds are not expected to pose a problem in revegetating the site." It is our experience that any time the existing vegetation is removed and the soil is disturbed, noxious weeds become a problem. Mowing of weeds may keep them in check, but eradication is much preferred and this requires a combination of techniques. Enc.

PLANNING COMMISSION HEARING DATE: November 9, 1999 PLANNING COMMISSION FUNCTION: Review the proposal for compliance with the City of Greeley's Comprehensive Plan and make a recommendation to the Weld County Commissioners. PROJECT OVERVIEW AND BACKGROUND: The original Use by Special Review Permit for gravel mining and a concrete and asphalt batch plant was approved by Weld County in the early nineties. At this time, the applicant is requesting to amend the existing Weld County permit in order to add an additional 70 acres and remove a small portion of Cell one from gravel extraction activity (see Attachment C). The amended special use permit boundary includes approximately 340 acres, of which 252 acres will be mined. The applicant has indicated that this will be a dry pit operation and will include seven phases. The total mining operation is anticipated to take 13 to 20 years depending on the market demand. It is expected that the operator will excavate approximately 15 to 25 acres per year and will operate continuously throughout this time period. There will be a maximum of 35 employees with two shifts of workers operating during daylight hours Monday through Saturday. All trucks associated with the use will exit the property onto 83r° Avenue and proceed north or south. The primary haul route will be 83"d Avenue to State Highway 34 (10th Street). A temporary access is proposed along 71s` Avenue at the point the Poudre River Trail intersects 715' Avenue, for the initial mining setup. FILE COPY The applicant has indicated that noise levels will comply with the requirements of the Weld County Health Department. All activities will be regulated by the Mine Safety and Health Act (MSHA) and the Occupation Safety and Health Act (OSHA). The noise level will need to comply with residential standards when the Poudre River Ranch PUD is developed. The reclamation of the land is proposed for water storage and wildlife habitat (Attachment D). It is the practice of the City of Greeley Planning Commission to review Weld County Referrals principally for conformance with the City's Comprehensive Plan policies. Specific design issues are addressed only to the degree necessary to ensure consistency with the City's Comprehensive Plan and Development Code. State Law and the Greeley Development Code require the mining of minerals of commercial grade prior to development.

Summary 2 WCR - CAMAS Mining USR KEY ISSUES/ANALYSIS: 1. Does the proposal comply with the City of Greeley's Comprehensive Plan? The applicable City Comprehensive Plan polices which address this request include: Comprehensive Plan Policy 4.3 All development is encouraged to be designed to promote compatibility among neighboring land uses of differing intensity and character. These efforts, where practical and appropriate, should include complementary landscaping, building massing, material selection, and site design. Staff Comment: Staff understands the importance of economically recoverable gravel and mineral extraction; however, the plans for such a use need to consider the neighboring residents and the community as a whole. This site is adjacent to the City limits and there may be dust and noise impacts to City residents to the south of the site at Poudre River Ranch, which is currently being developed. The views being marketed by the developer for the residential area will be highly disturbed during the 13-20 year mining cycle. Also, the applicant has indicated that the mining operation will be done during daylight hours Monday through Saturday. At certain times of year it is daylight as early as 5:30 a.m. Staff recommends that the mining operation have reasonable and specific hours of operation of 7:00 a.m. to 5:00 p.m. in winter months and 7:00 a.m. to 7:00 p.m. in summer months, with limited hours on Saturday mornings. The hours as proposed would not be compatible with the existing and developing neighboring land uses. The applicant identifies 71' Avenue as a temporary access, but does not identify how long this would be used as a temporary access and what is involved with the "set up" of the operation. Truck traffic generated from the set up and the continued operation of the mining would have a major impact to City residents south of the site. The City's Public Works Department recommends that traffic associated with the use be restricted from using 7l' Avenue in either direction south of the site because of the conflicts with adjacent residential traffic and student traffic from Northridge High School. The quality of life of surrounding residents and City residents to the south is important and the applicant should balance all interests through the design and Planning Comm. Summary 3 WCR - CAMAS Mining USR operation of the mining activity in order to be compatible with the surrounding residential land uses. Comprehensive Plan Policy 4.5 All development is encouraged to effectively mitigate any adverse environmental impact when development occurs in environmentally sensitive areas. Staff Comment: The site is located in an area identified as "high impact" in the City's Mapped Areas of Ecological Significance and a portion of the site is located where the future Poudre River Trail is planned. The City's position is that sand and gravel operation sites should be reclaimed in a manner that enhances both the natural environment and anticipates future land uses. With the mining activity, a number of existing wildlife habitat areas will be destroyed. Restoration plans for the designated "wildlife habitat restoration area" are sketchy. Water storage lakes or ponds have historically been shown to not be of much value to wildlife other than as temporary location for some waterfowl since water levels are drawn down generally throughout the summer during important nesting and spawning times. Without extensive shoreline habitat improvements, the lakes themselves have little habitat value. Cell one is referenced as not being "lined." There is no other reference to lining the other cells other than by inference as "storage." Lined lakes have even less habitat value since water tends to stagnate. In order to achieve an adequate habitat for the wildlife, re-vegetation plans should include appropriate herbaceous perennials in the grass seed mixture. Trees and shrubs selected for the site should primarily consist of native species, not ornamental varieties. In order to mitigate the adverse environmental impact this land use will have on the site, it is recommended that the habitat restoration and re-vegetation efforts be planned and monitored by a qualified wildlife biologist/ecologist. The Poudre River Trail is planned for construction on the southern perimeter of the site (Attachment F). There is a 100' foot easement shown for the trail in the area of Cell one. This is adequate for the trail purposes, however, it needs to be pointed out that construction of this section of the trail is expected to take place prior to mining activities in Cell one. The projected completion of the trail is June of 2000. The proposed conveyor crosses the trail in two locations. Any safety or security measures needed by the mining activities should be the responsibility of the mining operators, not the City or trail organization. Conversations between Planning Comm. Summary 4 WCR - CAMAS Mining USR City staff and the applicant indicate this is acceptable and that the mining operation will not interfere with the use of the trail by the public. An additional issue identified by City staff is the permit augmentation responsibilities for the site. Augmentation is the process of replacing evaporated water as a result of creating the large bodies of water from the mining process. It is unclear to staff who will be responsible for meeting the augmentation requirement, however, it should at least be identified with this review process. Staff suggests that clarification of the responsible party be a condition of amending this Special Review permit. ADMINISTRATIVE REVIEW TEAM COMMENTS: The Administrative Review Team reviewed this proposal informally at its meeting on October 27, 1999. Comments from the meeting have been addressed in this report and written response from the City's Natural Resource Planner is included as Attachment G. PLANNING STAFF RECOMMENDATION: The Planning staff recommends the Planning Commission find that the proposed amendment to the Special Review Permit for Gravel Mining and Concrete and Asphalt Batch Plant complies with the policies and intent of the City of Greeley's Comprehensive Plan, therefore, recommend approval with the following eight conditions: 1. Hours of operation shall be Monday through Friday 7:00 a.m. to 5:00 p.m. in the winter months and 7:00 a.m. to 7:00 p.m. in the summer months with limited hours on Saturday. 2. The temporary access on 7151 Avenue clearly defined as to the length of use and exact type of truck traffic. 3. All traffic generated from the Special Review Use shall be restricted from using 71" Avenue in either direction, south of the site, because of the conflicts with adjacent residential traffic and student traffic from Northridge High School. Planning Comm. Summary 5 WCR - CAMAS Mining USR 4. The reclamation plan shall be redesigned in order that the wildlife habitat restoration and re-vegetation efforts be planned and monitored by a qualified wildlife biologist/ecologist. 5. The Special Review Permit shall take into consideration the Poudre River Trail Project. 6. Clarification on who will be responsible for meeting the augmentation requirement for the site. 7. Noise generated from the site shall meet all City and State requirements. 8. A perimeter treatment plan shall be required along 7ls` Avenue and 83' Avenue.

A list of the names, addresses and the corresponding parcel identification numbers assigned by the Weld County Assessors Office for surrounding property owners is attached. 4. A list of the names and addresses of mineral owners and lessees of minerals on or under the parcel of land being considered in the amendment is attached. 5. A copy of the reclamation plans as submitted to the State of Colorado DMG is enclosed for review. Copies of the plan for obtaining water supplies, cross sections of drainage structures and profiles and typical cross sections of haul roads will be submitted if deemed necessary by the Board of County Commissioners. 6. This Use by Special Review application for a mining operation is consistent with the Weld County Comprehensive Plan. The Comprehensive plan allows for and encourages the extraction of sand and gravel deposits. CM. Goal 2 states that the County should promote the reasonable and orderly development of mineral resources. This application and accompanying materials clearly demonstrates compliance with this goal. All activities at the mining site are guided by the regulations of the Mine Safety and Health Act(MSHA) and the Occupational Safety and Health Act(OSHA). These requirements along with the Weld County Comprehensive Plan, specifically CM.Goal 4 which states minimize hazardous conditions related to mining activities and the mining site, will minimize or eliminate the potential adverse impact of the operation on surrounding properties. The application is proposing setbacks, noise controls, dust controls and general site conditions which will help to comply with the goals and policies of the Comprehensive Plan. Reclamation activities will be concurrent with the mining operation. Disturbances to the site will be minimized as much as possible. Wildlife habitat Weld County Planning CAMAS Colorado,Inc. Riverview Resource Mining Permit Page 3 on the site will be preserved throughout the mining by use of the wildlife habitat area located at the southern edge of Cell 4. In addition, the reclaimed use of water storage will further promote the use of the area for habitat location. 7. This application is located in the A(Agricultural) Zone District and is listed as a use allowed by special review under Section 31.4.1 of the Weld County Zoning Ordinance. 8. The subject site has a limited amount of prime agricultural ground. A majority of the property lies within the 100 year flood plain which limits the agricultural productiveness of the site. The area inhabited by the flood plain has historically been utilized as pasture land. 9. The protection of the health, safety and welfare of the inhabitants of the neighborhood and the County are being considered by the applicant. Possible fugitive dust emissions from the site will be minimized by watering and re- vegetation activities. Noise levels will comply with the requirements of the Weld County Health Department. Only one main access point will be used for the truck traffic at the site. Temporary access locations will be located along 71st Avenue for initial mining setup. Through measures taken by the applicant along with the Conditions of Approval and Development Standards as established by the County through the permitting process, the consideration of health, safety and welfare of Weld County citizens will be protected. 10. Surrounding land uses are primarily agricultural in nature. An existing sand and gravel operation exists to the west. A minor subdivision is located to the north. The City of Greeley is located to the southeast and the Cache La Poudre River lies along the south. Compatibility with surrounding land uses will be assured by setbacks,noise limitations, landscaping measures and Conditions of Approval and Development Standards as established by the County. 11. Future development of the area is described as open space. The use of sand and gravel mining with the reclaimed area being utilized as water storage will be consistent with the Weld County Comprehensive Plan. 12. The subject site is not located in a geologic hazard area or airport overlay district. However, the subject site does lie within a flood plain area. A flood hazard development permit will be submitted to adhere to all FEMA rules and regulations as described in Section 26 of the Weld County Zoning Ordinance.

Ser,taion Date: October 26, 1999 To: Debbie de Besche, Planner II From: Karen Scope!, Natural Resources Planner Subject: WCR 49:99 Camas Mining USR Here are my comments related to the proposal. POUDRE RIVER TRAIL: There is a 100' foot easement shown for the trail in the area of Cell 1. This is adequate for the trail purposes. However, it needs to be pointed out that construction of this section of trail is expected to take place prior to mining activities in Cell 1. (Projected completion is June of 2000). The proposed conveyor crosses the trail in two locations. Any safety or security measures needed by the mining activities will be the responsibility of the mining operators, not the City or trail organization. Conversations with CAMAS representatives have indicated this is acceptable to them and that they will not interfere with the use of the trail by the public. An agreement may be appropriate. WILDLIFE HABITAT ISSUES: This project is proposed in an area designated as "High Impact" in the City's Areas of Ecological Significance which also corresponds to habitat information provided to the County by the Colorado Division of Wildlife. Throughout the project narrative, references are made to "preserving" or improving wildlife habitat. It needs to be understood that a number of existing habitat areas will be destroyed. "Restoration plans" for the designated "wildlife habitat restoration area" are sketchy. "Water storage lakes or ponds" have historically been shown to not be of much value to wildlife other than as temporary locations for some waterfowl since water levels are drawn down generally throughout the summer during important nesting and spawning times. Without extensive shoreline habitat improvements, the lakes themselves have little habitat value. Cell 1 is referenced as not being "lined". There is no other reference to lining the other cells other than by inference as "storage". Lined lakes have even less habitat value since water tends to stagnate more. The proposed reclamation plan will "replace" existing land area wildlife habitat with large water bodies with limited habitat for birds, mammals, and fish unless standards are implemented that create more shoreline including "bays" with shallow water areas and islands within the lake bodies. Revegetation plans should include appropriate herbaceous perennials in the grass seed mixture. Trees and shrubs selected for the site should primarily consist of native species, not ornamental varieties. Perhaps existing trees and shrubs of appropriate size could be harvested into an on-site nursery or moved into areas being reclaimed. It is strongly suggested that habitat restoration and revegetation efforts be planned and monitored by a qualified wildlife biologist/ecologist - not an engineer. IMPACTS TO NEIGHBORING PROPERTIES IN THE CITY LIMITS: There may be dust and noise impacts to City residents to the south of the site at Poudre River Ranch. This area is currently being developed (no longer "vacant"). The "views" being marketed by the developer for the residential area will be highly disturbed during the 13 to 20 year mining cycle.

The information in the packet has been reviewed and Division Biologists,including myself have visited the site. Over the years I have reviewed several proposals for this parcel and, on behalf of the Division of Wildlife, have responded by letter at least five times. These letters should be in your files. The Division's concerns remain the same today as those expressed in earlier correspondence. Most of the site is situated in the flood plain of the Cache La Poudre River. The River channel, wetlands, warm-water sloughs, and dense vegetation associated with low elevation, cottonwood- willow riparian habitat,provide the most important wildlife habitat in Colorado. Alteration of this habitat due to development and increasing human activity can have a very negative impact on wildlife populations dependent on riparian areas. Therefore, from a Natural Resources and Community Development standpoint, it is essential that we plan for and develop these sites in a way that will minimize the permanent loss of key wildlife habitat. The Division has appreciated the efforts of your agency and the Weld County Commissioners to protect riparian areas through the Weld County Comprehensive Plan. There are also upland areas on this parcel. These sites,primarily along O Street, are composed of irrigated agricultural fields put to yearly tillage and subinigated pasture. Because irrigated Ag. fields are plowed regularly,they have little value for wildlife. Geese, ducks, deer and other herbivores glean the crop residue, and standing crops may provide escape cover to many species. However the fields are most important in that they provide a safe haven during high water events, escape from summer insect concerns, and a movement corridor at times of the year when wildlife needs to move away from the River. Based on these considerations, the Division's main concerns involving this development are: the narrowing of the riparian corridor associated with the Poudre River, obstruction of movement for free ranging wildlife, loss of warm-water sloughs, loss of wetlands, loss of subirrigated pasture necessary for preservation of an intact riparian ecosystem, loss of intact wildlife movement corridors along the River as well as onto upland areas, loss of potential habitat for listed threatened and endangered species, water quality issues that may impact small fish habitat, and permanent loss of wildlife value because of increased human disturbance. The Division also feels that the reclamation plan should address potential recreational/wildlife use of the site post mining. In this letter, I will touch on each of thee.icalpc 2 It is essential to maintain an intact, unobstructed riparian corridor of adequate width to provide for the needs and movement of wildlife. The United States Fish and Wildlife Service(USFWS)has identified this reach of the Poudre River and upstream as a Potential Mouse Protection Area for the Federal and State listed Preble's meadow jumping mouse, Zapus hudsonius prebliei. Currently, they are recommending a non-disturbance zone of 100 yards from the centerline of waterways, in either direction, for preservation of Preble's habitat. In discussion on the final guidelines to be incorporated in the yet to be completed 4D ruling, some biologists are suggesting that the non-disturbance zone be extended to 100 feet beyond the 100 year flood zone. Until the 4D rule has been finalized and adopted there is no official setback. Therefore, unless modified by the USFWS, the Division will recommend the 100 yard setback from centerline of the River as a non-disturbance zone on this property. It seems reasonable to honor the conservative standard of 100 yards from the centerline of the river, as a minimum setback for non-development along the riparian corridor. In doing this the crucial riparian corridor, essential for species protection and movement by free ranging wildlife would remain intact. Additionally the Division would recommend that diking in or near the flood zone, intended to "contain"the river, should not be installed. The ecosystem along Plains streams in Colorado is adapted for and regenerated by periodic flooding. Diking and other attempts at controlling the River are prone to failure,negatively impact riverbottom wet meadows, and adversely affects upstream and downstream neighbors. There is a good reason why development is discouraged in these areas. Ill-designed fencing in and adjacent to the flood plain of the River can trap and injure wildlife. Improperly designed fences set along road margins increase the hazard of car/deer strikes. Therefore, the Division of Wildlife would recommend that perimeter fencing and interior fencing on this site be kept to a minimum. When necessary, the fences should be of a type that will allow the free movement of wildlife. Chain link or other fine mesh fencing material should not be used on this site unless absolutely necessary. These types of fencing should not be used to fence perimeters. Split rail, barb- wire and three strand smooth/barb wire fences are acceptable alternatives for wildlife. I've included a couple of designs that provide proper wire spacing for use by wildlife. Where needed,fences paralleling roads should be set back 50-100 yards from the edge of the road to allow space for wildlife to view the road before crossing. We recognize the need of the pit operator to maintain security for the site. If installed, security fencing around the processing area/batch plant should in several locations be raised two to three inches above ground surface to allow free movement of small mammals. However, there are many gravel sites along the Poudre, including the Hall Irwin site at 83t Ave, that operate without extensive security fencing. Therefore there does not seem to be a need. Warm water sloughs on the property need to be protected to preserve open water when the site is reclaimed. Warm water sloughs are essential for protecting and holding waterfowl and other wildlife during bitter cold spells. In the original County Permit the protection of the west slough was stipulated as part of the permit requirements. There should be a letter on file from the Division to Shani Eastin, of Tuttle Applegate, outlining our agreement for protection of this slough. The division would recommend that other warm water and sloughs found on site should be similarly protected. The pond shoreline contour suggested by Camas Exhibit F for all reclaimed ponds is 3:1 at water edge and 2:1 at a 10 foot depth. These are standards suggested by the Mined Land Reclamation Board primarily for safety purposes. The reclamation plan for the site suggests that the ponds will be reclaimed as water storage reservoirs(fully lined pits). If this is the case, at times some of the ponds will be drawn down eight or more feet. When this happens the 2:1 contour will be at shoreline. DEPARTMENT OF NATURAL RESOURCES,Greg Watcher,Executive Director 3 Therefore the Division would recommend a 3:1 contour for all lined ponds as a minimum standard. This should not diminish storage capacity since all areas within the liner including groundwater is considered storage. The reclamation plan also states that the other two intents for reclamation are wetlands and wildlife habitat. We applaud Camas' decision to maintain this portion of the Poudre River Corridor as a prime wildlife area! To maximize the habitat potential of this site post mining, and offset the significant loss of riverbottom habitat resulting from the excavation of pits and installation of lined reservoirs, the Division would recommend that careful consideration be given to the shapes and contours of the completed pits. Limed, rectangular pits of 2:1 slope offer little vahie as wildlife habitat and/or wetlands. Lined pits,prone to periodic dewatering offer little in fishery value. Rectangular pits of 2:1 slope offer little in esthetic, recreational value. The Division would recommend that reclamation of the pits should establish curved,irregular shorelines with shoals, coves and peninsulas. These protected areas provide sanctuary for water birds and others in rough weather. Portions of the shoreline should be reclaimed with shallower slope contours that would allow the restablishment of wetland plant communities. Contours of 8:1 or shallower will allow the growth of wet grass meadows, rush/sedge wetlands, bullrush and cattail thickets. Since many acres of this habitat type will be removed during mining it is imperative to attempt to rebuild as much wet meadow as possible. When established inside the liner they will store water and may cut down on evaporative loss. Islands may be constructed in the center of the ponds to provide nesting/resting habitat for water birds. The bottom of ponds should be left irregular and uneven. Large tree trunks, scrap concrete and other suitable materials can be deposited in the bottoms and along the edge of the ponds to provide fish structure. The Division can provide information and support in designing fish "reefs"and other aquatic habitat. In other area pits, the Division has worked with Boy Scouts and other groups to install tire reefs and other structure prior to filling new reservoirs while it is easiest to accomplish. Reservoirs should be designed to provide a conservation pool of appropriate size to protect fish during dewatering. Revegetation of mined areas is difficult and may take years. We appreciate Camas' intent to perform in progress reclamation! In other pits we've been involved with,it seems to allow for the quickest site recovery. Noxious weeds are a problem in most reclamation efforts. The reveg plan states that Camas will mow during the first growing season if necessary to control noxious weeds. The Division would recommend a long-term weed plan be developed for the site, including unmined areas. They will in all likelihood need a plan. Ron Broda, the Weld County Weed Inspector, can help them devise a plan that will protect the property and surrounding lands. The seed mixture suggested in the reveg. plan seems composed for upland sites. I spoke with the range experts at the Natural Resources Conservation Service(NRCS) about this plan. They suggested that the Luna Pubescent Wheatgrass and Lincoln Smooth Bromegrass be removed from the plant mixture. They also suggested, and I strongly agree, that Reed Canary Grass,Alkali Cordgrass, Yellow lndiangrass, and Green Needlegrass be added to the mixture to reestablish the wet meadow complex. I would also suggest that one or more appropriate legumes for the site be included in the mix. A dryland Alflafa, Sweetclover, or Bird's Foot Trefoil could be added to provide cover, stand heterogeneity, and nitrogen fixing capability. Representatives of the NRCS have told me they would be happy to provide appropriate seed mixtures for the site. Mud clumps of cattatil and bullrush can be dumped at water's edge to start the reestablishment of the marsh habitat. DEPARTMENT OF NATURAL RESOURCES,Greg Welcher,Executive Director 4 Scotch Pine and Austrian Pine may, with great effort, work on upland sites, but would probably have a tough go in the alkaline, wet meadows of the flood plain. Therefore, theses species may be taken off the planting list. Eastern Red Cedar should be used in the River bottom over the Rocky Mountain Juniper. Additional tree species that may be considered include: Green Ash, Boxelder and Black Walnut. Additional shrub plants to consider include: wild grape, Cotoneaster, Golden Current, Skunkbush Sumac, and wild rose. The Division would recommend that emphasis be given to establishing shrub thickets over trees. Shrub thickets have higher wildlife value. In and close to the River bottom shrub thickets have been identified as high priority for Preble's mice. If the ponds are lined, careful consideration should be given to the location of tree plantings. In other lined pits I've worked on, there was great concern that deep reaching tree roots may penetrate and compromise the integrity of the pond liner. Plantings should be located in areas that will not interfere with grass seeding, mowing and other mechanized activities needed for establishing the grass stand. Regardless of whether the plantings are comprised of trees or shrubs,the installation should be done using a weed barrier and mulch cover. This technique protects plantings, maintains moist soil for rapid growth and greatly improves survivability of the plant. Finally, if it has not been done, it would be wise for the applicant to complete surveys in all appropriate areas on this parcel for Preble's meadow jumping mouse, and the Ladies'-Tresses, Spiranthes diluvialis, prior to onset of mining. We assume that wetland delineation has already occurred and if necessary the Corp of Engineers has been consulted. On behalf of the Division, I have appreciated the opportunity to review and comment on this proposaL Be assured that I am available to discuss any questions that Camas, Tuttle Applegate or you may have.

Section 32: Portions of the N%: Weld County, Colorado Ladies and Gentlemen: With respect to the referenced public hearing for the Site Specific Development Plan and Special Review Permit for gravel mining, please be advised that Patina Oil & Gas Corporation ("P atina") is the owner of the oil and gas estate under the referenced lands (the "Lands"). Patina is very concerned about the impact the mining operation will have on Patina's ability to develop, produce, operate and maintain oil and gas wells on the Lands. Patina has not waived any rights it has to access the oil and gas under the Lands. Patina has the right to drill oil and gas wells on the Lands pursuant to existing Colorado Oil & Gas Conservation Commission well location rules. Patina requests assurance from Welc. County and CAMAS Colorado, Inc. that the proposed mining operation will not block access or preclude Patina from drilling, producing, operating and maintaining oil and gas wells on the Lands. Until this matter is resolved by agreement with CAMAS Colorado, Inc., Patina is not waiving its rights as a leasehold owner. Any approval of the mining operation should be conditioned upon the preservation of Patina's real property rights that allow it to make a reasonable use of the surface of the Lands for oil and gas development. Patina requests that these comments be entered into the record. If you have any question, please feel free to contact the undersigned at(303) 389-3600. Sincerely, PAT, OIL &G S CORPORAITON David W.
