6 Unpaved roads are the largest source of particulate air pollution in the United States Effects of dust from unpaved roads: Stunting plant growth due to the shading effect and clogging of the plant s pores Nuisance and health problems such as hay fever and allergies Reduction in visibility and causing driving hazards for drivers Increasing particulate loading of lakes and streams after precipitation 6

7 Due to the increased traffic volumes related to energy sector in western North Dakota, dust along the many unpaved roads is causing many complaints Farmers and ranchers complain that dust from unpaved roads due to heavy trucks has stunted crops, damaged pasture, and caused allergic reactions in livestock There is a need to measure the amount of dust and its effect on crops & livestock 7

8 Literature review of the effect of dust from unpaved roads on crops and livestock Measure and compare dust from unpaved roads in five counties in North Dakota considering traffic, material type, and weather conditions Determine the effect of dust from unpaved roads on crops and livestock using survey 8

17 The amount of dust from unpaved roads in five counties have been collected monthly using mason jars at 2, 3, and 4 ft on each metal posts that are at 30, 60, 120, 240, and 480 ft from the center of major unpaved road on both sides July-August August-September September-October will be collected in October Traffic counters have been used to collect traffic volume, traffic speed, and vehicle length Survey data will be used to determine the effect of dust and livestock on crop yield and livestock 17

24 Williams and McKenzie sites have high traffic and dust amount as compared to the three other counties There has been a significant traffic increase at McKenzie site from August-September as compared to July-August Dust from Mountrail site is negligible for August- September may be because of dust suppressants and lesser traffic as compared to the other western counties Maximum speed that is higher than interstate speed limit has been measured 24

25 Collecting dust and traffic data in October Analyze dust and traffic data in detail Consider weather, material types, and dust suppressants if any Gather and analyze survey results from farmers and ranchers to determine the effect of dust on crop yield and livestock Submit report on October 31 st and make closing presentation in November 25
