This is a presentation given by the Wimberley Valley Watershed Association to the Wimberley City Council on March 11th. This presentation is a collection of scientific data and maps showing the possible negative impacts of the Permian Highway Pipeline to our environment, our safety, our tourism economy, our landowner rights and property values.

These slides show the Pipeline route overlaid on top of our existing karst features, endangered species habitat, water wells, aquifers, and highly populated areas.

WVWA Presentation on the Permian Highway Pipeline

  1. 1. Kinder Morgan Permian Highway Pipeline Wimberley City Council
  2. 2. • Avoid the senstive topography and aquifers of the Hill Country • Avoid population density and growth • Are within 30 miles of the current pipeline length Alternate Routes
  3. 3. Contributing Zones of the Aquifer
  4. 4. Watershed Boundaries & Cave Features/Karst Terranes
  5. 5. Voids, Caves & Sinkholes
  6. 6. Springs
  7. 7. Public Water Supply Wells
  8. 8. • Avoid the senstive topography and aquifers of the Hill Country • Avoid population density and growth • Are within 30 miles of the current pipeline length Alternate Routes
  9. 9. Explosions, Leaks & Evacuations For the Permian Highway Pipeline, the evacuation zone is a 1.4 mile diameter from the line. Fire supression contaminants will enter the aquifer and contaminate groundwater in an event such as this.
  10. 10. New Mexico: Dec. 2018  250,000 gal. Of gasoline were spilled into an agricultural ditch  168,000 gal. Were recovered  82,000 gal. Lost  How much oil, gas, and other hydrocarbons would we lose in our karst aquifers?
  11. 11. Questions & Concerns Has KM estimated the number of karst features? What are the construction methods to eliminate potential impacts to karst features? Will KM develop a void mitigation plan? Will background water-quality sampling of wells be conducted? Will the pipeline be double-walled? Will KM conduct ongoing sampling of Trinity & Edwards Aquifer wells for possible pipeline contaminants? What liquids might be in the pipeline and how much could be released if a leak or spill occurs? Will KM notify GCDs if pipeline switches from transporting natural gas to crude or other liquid? What resources will be in place to respond in the event of a leak/contamination? In the event of drinking water contamination, what actions will be taken to protect water users?
