Underground Injection Control

  1. 2. <ul><li>To increase ground water protection, a federal Underground Injection Control (UIC) program was established under the provisions of the Safe Drinking Water Act of 1982. </li></ul><ul><li>The UIC Program is responsible for regulating the construction, operation, permitting, and closure of injection wells that place fluids underground for storage or disposal. </li></ul>
  2. 3. waste disposal, enhancing oil production, mining, and preventing salt water intrusion. # Injection well categorized into Five Classes.
  3. 4. <ul><li>USDW : An underground source of drinking water (USDW) is an aquifer or a part of an aquifer and contains water that is less than 10000 PPM total dissolved solid </li></ul><ul><li>It is used as a drinking water source or may be needed as a drinking water source in the future.  USDW is having specific functions. </li></ul><ul><li>Injection wells are regulated by either a state agency or one of EPA's regional offices. </li></ul>
  4. 5. <ul><li>The use of injection wells was documented as early as A.D. 300.  However, large-scale commercial use of injection wells in the U.S. really began in the 1930s. </li></ul><ul><li>In 1980, Congress passes the Hazardous and Solid Waste Amendments (HSWA) to the Resource Conservation and Recovery Act (RCRA), requiring additional UIC regulations for deep wells injecting hazardous waste. </li></ul>
  5. 6. <ul><li>Primary States – States that have received primary enforcement authority for the UIC Program. </li></ul><ul><li>Territories – U.S. Territories that have primary enforcement authority for the UIC Program. </li></ul><ul><li>EPA Regions that directly implement the UIC Program in a state. </li></ul>
  6. 7. <ul><li>CLASS-1 </li></ul><ul><li>Industrial and Municipal waste disposal wells </li></ul>
  7. 8. <ul><li>Class 2 </li></ul><ul><li>OIL AND GAS RELATED WELLS </li></ul>
  8. 9. <ul><li>Class III </li></ul><ul><li>Inject fluids to dissolve and extract minerals such as uranium, salt, copper, and sulfur. </li></ul>
  9. 10. <ul><li>Class IV </li></ul><ul><li>Shallow wells used to inject hazardous or radioactive wastes into or above a geologic formation that contains a USDW. </li></ul><ul><li>In 1984, EPA banned the use of Class IV injection wells for disposal of hazardous or radioactive waste. </li></ul>
  10. 11. <ul><li>Class V wells are used to inject non-hazardous fluids underground. </li></ul><ul><li>To dispose of wastes into or above underground sources of drinking water </li></ul><ul><li>Most Class V wells are shallow disposal systems that depend on gravity to drain fluids directly in the ground. There are over 20 well subtypes that fall into the Class V category and these wells are used by individuals and businesses to inject a variety of non-hazardous fluids underground. </li></ul>Class V
  11. 13. <ul><li>* Geologic Sequestration of Carbon Dioxide </li></ul><ul><li>Geologic sequestration (GS) is the process of injecting carbon dioxide (CO2) from a source, such as a coal-fired electric generating power plant </li></ul><ul><li>Risk-drinking water, organic leaching, </li></ul><ul><li>dissolution of metal </li></ul><ul><li>* Hydraulic Fracturing </li></ul><ul><li>Hydraulic fracturing is the injection of fluid under pressure to facilitate the production of oil and natural gas. </li></ul>
