Seismic survey company outlines plan to place buried receivers on district property; company cites 360‑sq‑mile project and 12‑day recording windows
Summary
Silverthorne Seismic representative Daniel described a 3‑D seismic survey covering ~360 square miles, said on‑site receivers would be buried up to a foot and record for about 12 days, and addressed questions about buffers from structures, PPV testing, and lease payments (one figure cited was $20).
Daniel, a representative of Silverthorne Seismic (speaker 6), requested permission to conduct a 3‑D seismic survey in the region covering roughly 360 square miles that includes Centerville, Buffalo and Hewitt. Daniel explained the company’s proposed on‑site practice: in fields they would use drill charges (higher energy), but on city streets they would use vibratory equipment (vibroseis). For school sites the company said receivers would be buried no more than one foot and would remain in place to record for approximately 12 days before crews returned to pick them up.
"My name is Daniel. We're, with Silverthorne Seismic," Daniel said as he introduced the presentation. He described the hazard‑survey step (mapping buildings and placing buffers from structures and pipelines) and said the team conducts PPV (peak particle velocity) tests to set safe distances from sensitive infrastructure. On the question of payments, Daniel said companies typically place lease amounts on the lease instrument and cited $20 as a recurring figure in recent leases, while acknowledging amounts can vary by property and prior lease terms.
Trustees and attendees raised concerns about drilling versus vibration on fields, how long equipment would remain on school property, and whether mineral owners can override surface owners; Daniel said mineral owners can supersede surface rights for certain oil/mineral activities but noted procedures differ when seismic versus drilling/production is proposed. The company left photos and contact information for follow‑up; the board did not take immediate action and requested staff to coordinate notification and any required permissions.
