Straw Wattle – Erosion Control – Construction Site – Fairbanks, Alaska

Straw Waddle - Erosion Control - Construction Site - Fairbanks, Alaska

Straw wattle placed around street storm drain in Fairbanks, Alaska, to prevent soil erosion, adjacent to a construction site with loose disturbed sediment.

Erosion control measures are essential at construction sites to prevent soil erosion, sediment displacement, and environmental damage. Common erosion control features include:

  1. Silt Fences: Temporary barriers made of geotextile fabric that trap sediment while allowing water to flow through. Installed along site perimeters or downslope areas.
  2. Sediment Basins and Traps: Structures designed to collect and settle sediment-laden runoff, preventing it from entering waterways.
  3. Erosion Control Blankets: Biodegradable mats or nets that stabilize disturbed soil and protect against water and wind erosion.
  4. Straw Wattles (Fiber Rolls): Cylindrical rolls of straw, coconut fiber, or similar material placed on slopes to slow water flow and trap sediment.
  5. Check Dams: Small, temporary barriers placed in drainage channels to slow water flow and reduce erosion.
  6. Vegetative Cover: Planting grasses or other vegetation to stabilize soil and minimize erosion. Often used for long-term control.
  7. Riprap: Layers of large stones or rocks placed in areas of high water flow to reduce erosion and stabilize slopes.
  8. Diversion Channels: Trenches or channels that redirect stormwater away from vulnerable areas to minimize erosion.
  9. Dust Control Measures: Spraying water, using mulch, or applying soil binders to reduce wind erosion.
  10. Gravel Construction Entrances: Stabilized entry points for vehicles to reduce the tracking of sediment onto nearby roads.

These measures are often used in combination to create a comprehensive erosion and sediment control plan for construction sites.

Coal Loading and Storage at Power Plant – Utah

Coal Loading and Storage at Power Plant - Utah

A coal loading and storage facility at a coal power plant plays a crucial role in managing the supply of coal used to generate electricity. These facilities are designed to efficiently handle large quantities of coal, ensuring a consistent supply to the plant’s boilers. Coal arrives at the facility via railcars, trucks, or conveyor systems and is stored in large piles or silos before being transported to the power plant’s combustion systems. Storage areas are often equipped with conveyor belts, hoppers, and stackers to streamline the loading, unloading, and sorting processes. To prevent environmental contamination and ensure safety, modern facilities implement dust control measures, containment systems, and sometimes even covered storage areas.

The storage facility ensures that coal is readily available even during disruptions in the supply chain, such as transportation delays. It also allows for blending different grades of coal to optimize combustion efficiency and reduce emissions. These facilities are integral to the operational reliability of coal power plants, ensuring uninterrupted electricity production while adhering to regulatory standards for environmental protection and workplace safety.

Coal power has historically been a significant source of energy in Utah, playing a crucial role in the state’s economy and energy production. As of recent years, coal-fired power plants have accounted for a substantial portion of Utah’s electricity generation, though this share is gradually declining as renewable energy sources grow in prominence. Utah’s coal reserves, primarily located in the Book Cliffs and Wasatch Plateau regions, have supported a robust mining industry for decades, providing fuel for both in-state power plants and out-of-state markets.

Major coal-fired power plants in Utah include Hunter Power Plant near Castle Dale and Huntington Power Plant near Huntington, both operated by PacifiCorp’s Rocky Mountain Power. These plants generate reliable baseload electricity, but they also contribute to air pollution and greenhouse gas emissions, prompting increasing scrutiny and regulatory pressure. In response to environmental concerns and market trends, Utah is transitioning toward cleaner energy sources like natural gas, wind, and solar. Nevertheless, coal remains a key part of the state’s energy mix, supporting jobs and providing affordable electricity, even as its role diminishes in favor of a more sustainable energy future.

Reduce Car Pollution Campaign Sign – Utah

Turn Your Key, Be Idle Free - Utah

Turn Your Key, Be Idle Free” is a widely recognized environmental campaign in Utah aimed at reducing vehicle idling to improve air quality and promote healthier communities. Launched in response to concerns about air pollution, particularly during Utah’s winter inversion season, the initiative encourages drivers to turn off their engines when parked or waiting for extended periods.

The campaign highlights the environmental and health benefits of reducing idling, including decreasing harmful emissions like carbon dioxide, nitrogen oxides, and particulate matter. It also emphasizes the economic advantages of saving fuel and reducing engine wear. Many schools, businesses, and municipalities in Utah support the “Idle Free” movement by displaying signage and adopting policies that encourage drivers to minimize idling.

“Turn Your Key, Be Idle Free” has become a rallying cry for community members and organizations committed to cleaner air and sustainable practices, playing a significant role in raising awareness and fostering a culture of environmental responsibility throughout Utah.
