RIGHT TO EXTRACT MINERAL RESOURCES STATEMENT: WELD COUNTY HAS SOME OF THE MOST ABUNDANT MINERAL RESOURCES, INCLUDING, BUT NOT LIMITED TO, SAND AND GRAVEL, OIL, NATURAL GAS, AND COAL.

OFTENTIMES, MINERAL RESOURCES ARE PROTECTED PROPERTY RIGHTS AND MINERAL OWNERS SHOULD BE AFFORDED THE OPPORTUNITY TO EXTRACT THE MINERAL RESOURCES. 29. THE WELD COUNTY RIGHT TO FARM STATEMENT, AS IT APPEARS IN SECTIONS 22-2-20J.2 OF THE WELD COUNTY CODE, SHALL BE PLACED ON THE MAP AND RECOGNIZED AT ALL TIMES. 30. PRIOR TO THE RELEASE OF BUILDING PERMITS, THE APPLICANT SHALL BE REQUIRED TO SUBMIT A COMPLETE ACCESS APPLICATION FOR A COMMERCIAL ACCESS AS SHOWN ON THIS PLAN. WELD COUNTY IS ONE OF THE MOST PRODUCTIVE AGRICULTURAL COUNTIES IN THE UNITED STATES, TYPICALLY RANKING IN THE TOP TEN COUNTIES IN THE COUNTRY IN TOTAL MARKET VALUE OF AGRICULTURAL PRODUCTS SOLD. THE RURAL AREAS OF WELD COUNTY MAY BE OPEN AND SPACIOUS, BUT THEY ARE INTENSIVELY USED FOR AGRICULTURAL. PERSONS MOVING INTO A RURAL AREA MUST RECOGNIZE AND ACCEPT THERE ARE DRAWBACKS, INCLUDING CONFLICTS WITH LONG-STANDING AGRICULTURAL PRACTICES AND A LOWER LEVEL OF SERVICES THAN IN TOWN. ALONG WITH THE DRAWBACKS COME THE INCENTIVES WHICH ATTRACT URBAN DWELLERS TO RELOCATE TO RURAL AREA : OPEN VIEWS, SPACIOUSNESS , WILDLIFE, LACK OF CITY NOISE AND CONGESTION AND THE RURAL ATMOSPHERE AND WAY OF LIFE WITHOUT N EIGHBORING FARMS, THOSE FEATURES WHICH ATTRACT URBAN DWELLERS TO RURAL WELD COUNTY WOULD QUICKLY BE GONE FOREVER. AGRICULTURAL USERS OF LAND SHOULD NOT BE EXPECTED TO CHANGE THEIR LONG ESTABLISHED AGRICULTURAL PRACTICES TO ACCOMMODATE THE INTRUSIONS OF U RBAN USERS INTO A RURAL AREA. WELL -RUN AGRICULTURAL ACTIVITIES WILL GENERATE OFF SITE IMPACTS, INCLUDING NOISE FROM TRACTORS AND EQUIPMENT ; SLOW MOVING FARM VEHICLES ON RURAL ROADS ; DUST FROM ANIMAL PENS, FIELD WORK, HARVEST AND GRAVEL ROADS; ODOR FROM ANIMAL CONFINEMENT, SILAGE AND MANURE; SMOKE FROM DITCH BURNING; FLIES AND MOSQUITOES ; HUNTING AND TRAPPING ACTIVITIES; SHOOTING SPORTS, LEGAL HAZING OF NUISANCE WILDLIFE; AND THE USE OF PESTICIDES AND FERTILIZERS IN THE FIELDS , INCLUDING THE USE OF AERIAL SPRAYING. IT IS COMMON PRACTICE FOR AGRICULTURAL PRODUCERS TO UTILIZE AN ACCUMULATION OF AGRICULTURAL MACHINERY AND SUPPLIES TO ASSIST IN THEIR AGRICULTURAL OPERATIONS. A CONCENTRATIONS OF MISCELLANEOUS AGRICULTURAL MATERIALS OFTEN PRODUCES A VISUAL DISPARITY BETWEEN RURAL AND URBAN AREAS OF THE COUNTY. SECTION35-3.5-102, C.R.S. PROVIDES THAT AN AGRICULTURAL OPERATIONS SHALL NOT BE FOUND TO BE A PUBLIC OR PRIVATE NUISANCE IF THE AGRICULTURAL OPERATION ALLEGED TO BE A NUISANCE EMPLOYS METHOD OR PRACTICES THAT ARE COMMONLY OR REASONABLY ASSOCIATED WITH AGRICULTURAL PRODUCTIONS. WATER HAS BEEN AND CONTINUES TO BE, THE LIFELINE FOR THE AGRICULTURAL COMMUNITY. IT IS UNREALISTIC TO ASSUME THAT DITCHES AND RESERVOIRS MAY SIMPLY BE MOVED "OUT OF THE WAY" OF RESIDENTIAL DEVELOPMENT. WHEN MOVING TO THE COUNTY, PROPERTY OWNER AND RESIDENTS MUST REALIZE THEY CANNOT TAKE WATER FROM IRRIGATION DITCHES, LAKES OR OTHER STRUCTURES, UNLESS THEY HAVE AN ADJUDICATED RIGHT TO THE WATER. WELD COUNTY COVERS A LAND AREA OF APPROXIMATELY FOUR THOUSAND (4,000) SQUARE MILES IN SIZE (TWICE THE SIZE OF THE STATE OF DELAWARE) WITH MORE THAN THREE THOUSAND (3,700) MILES OF STATES AND COUNTY ROADS OUTSIDE OF MUNICIPALITIES. THE SHEER MAGNITUDE OF THE AREA TO BE SERVED STRETCHES AVAILABLE RESOURCES. LAW ENFORCEMENT IS BASED ON RESPONSES TO COMPLAINT MORE THAN ON PATROLS OF THE COUNTY, AND THE DISTANCES WHICH MUST BE TRAVELED MAY DELAY ALL EMERGENCY RESPONSES, INCLUDING LAW ENFORCEMENT, AMBULANCE AND FIRE. FIRE PROTECTION IS USUALLY PROVIDED BY VOLUNTEERS WHO MUST LEAVE THEIR JOBS AND FAMILIES TO RESPOND TO EMERGENCIES COUNTY GRAVEL ROADS, NO MATTER HOW OFTEN THEY ARE BLADED, WILL NOT PROVIDES THE SAME KIND OF SURFACES EXPECTED FROM A PAVED ROAD. SNOW REMOVAL PRIORITIES MEAN THAT ROADS FROM SUBDIVISIONS TO ARTERIALS MAY NOT BE CLEARED FOR SEVERAL DAYS AFTER A MAJOR SNOWSTORM. SERVICES IN RURAL AREAS, IN MANY CASES, WILL NOT BE EQUIVALENT TO MUNICIPAL SERVICES. RURAL DWELLERS MUST, BY NECESSITY, BE MORE SELF-SUFFICIENT THAN URBAN DWELLERS. PEOPLE AREA EXPOSED TO DIFFERENT HAZARDS IN THE COUNTY THAN IN AN URBAN OR SUB -URBAN SETTING. FARM EQUIPMENT AND OIL FIELD EQUIPMENT, PONDS AND IRRIGATION DITCHES, ELECTRICAL POWER FOR PUMPS AND CENTER PIVOT OPERATIONS, HIGH SPEED TRAFFIC, SAND BURS, PUNCTURE VINES, TERRITORIAL FARM DOGS AND LIVESTOCK AND OPEN BURNING PRESENT REAL THREATS. CONTROLLING CHILDREN'S ACTIVITIES IS IMPORTANT, NOT ONLY FOR THEIR SAFETY, BUT ALSO FOR THE PROTECTION OF THE FARMER'S LIVELIHOOD.

CLEAR (GRUB IF NECESSARY) SITE FOR PERIMETER EROSION AND SEDIMENT CONTROLS (BMP'S) ONLY. 10. INSTALL TEMPORARY PERIMETER BMPs. 11. ROUGH GRADE ROADS) AND LAYDOWN/MATERIAL STORAGE AREA IMPORTING MATERIAL AS NECESSARY FROM ON -SITE OR OFF -SITE SOURCE PER PROPOSED GRADES PROVIDED TO CREATE OR MAINTAIN POSITIVE DRAINAGE. 12. INSTALL STABILIZED CONSTRUCTION ROADS. 12.1. STABILIZED CONSTRUCTION ROADS ARE CONSIDERED A BMP. IT IS THE INTENT OF THE DESIGN THAT STABILIZED CONSTRUCTION ROADS ARE INSTALLED PRIOR TO GRADING, ARRAY CONSTRUCTION, AND EQUIPMENT PAD CONSTRUCTION. 13. CONSTRUCT THE SOLAR PLANT. 14. PERFORM TEMPORARY STABILIZATION SEEDING OF DISTURBED AREAS IF REQUIRED. 15. CONSTRUCT PERMANENT BMPs. 16. STABILIZE ALL REMAINING DISTURBED AREAS WITH PERMANENT VEGETATION OR SITE SPECIFIC VEGETATION AS NOTED INCLUDING TOP SOILING, FERTILIZING, AND MULCHING, IF REQUIRED. 17. REMOVE CONSTRUCTION ENTRANCE, COMPLETE FINAL GRADE AND RESTORATION OF GRAVEL ENTRANCE. 18. STABILIZATION OF ALL AREAS DISTURBED BY REMOVAL OF BMP'S WILL BE PERFORMED PRIOR TO FINAL INSPECTION. 19. ALL MAINTENANCE OF THE FINAL SITE AND PERMANENT BMP'S SHALL BE CONTROLLED BY SITE OWNER. 20. IF THE SEQUENCE OF CONSTRUCTION AND BMP INSTALLATION IS MODIFIED BY THE CONTRACTOR. THE CONTRACTOR SHALL SUBMIT TO THE ENGINEER THESE CORRECTIONS TO UPDATE THE GRADING, EROSION AND SEDIMENT CONTROL PLAN. THE SWMP DESIGNER SHALL UPDATE THE SWMP. THESE CHANGES SHALL BE APPROVED BY THE AHJ PRIOR TO IMPLEMENTATION. INSPECTIONS AND MAINTENANCE OF EROSION & SEDIMENT CONTROL BMP'S (TEMPORARY): 21. THE DESIGNATED SWMP INSPECTOR SHALL INSPECT ALL DISCHARGE POINTS, DISTURBED AREAS, MATERIAL STORAGE AREAS, STRUCTURAL CONTROLS AND CONSTRUCTION ENTRANCES/EXITS IN ACCORDANCE WITH THE APPROVED SWMP. ALL OBSERVATIONS AND INCIDENTS OF NON-COMPLIANCE, CORRECTIVE ACTIONS, AND MAINTENANCE SHALL BE RECORDED IN THE SWMP INSPECTION REPORT. 22. INSPECTIONS OF BMP'S SHALL BE DOCUMENTED AND SIGNED BY THE CERTIFIED SWMP INSPECTOR AND PROVIDED TO PROJECT MANAGEMENT AND CONTRACTOR. 23. IF BMP INSPECTION REPORTS DO NOT IDENTIFY INCIDENCES OF NON-COMPLIANCE, THE BMP INSPECTION REPORT SHALL CONTAIN A CERTIFICATION THAT THE FACILITY IS IN COMPLIANCE WITH THE CGP AND THE SWMP. 24.

BMP'S DETAILED IN THE EROSION AND SEDIMENT CONTROL PLAN ARE ONLY AN ESTIMATE OF WHAT NEEDS TO BE IMPLEMENTED PRIOR TO AND DURING CONSTRUCTION. IF BMP INSPECTIONS IDENTIFY AREAS OF THE PROJECT SITE WHERE PROPERLY INSTALLED BMP'S ARE NOT CONTROLLING FLOW OF SEDIMENT OFF -SITE, IT IS THE CONTRACTORS OBLIGATION TO IMPLEMENT COST EFFECTIVE/PRACTICAL BMP'S WHILE GRADING AND CONSTRUCTION ACTIVITIES ARE OCCURRING. 26. EROSION AND SEDIMENT CONTROL DRAWINGS ARE SUBJECT TO ADDITIONAL, NEW AND ALTERNATIVE BMP'S WHEN REQUESTED OR APPROVED BY THE ENGINEER, CERTIFIED SWMP INSPECTOR, OR AHJ. 27.
