Description

The State of South Carolina is soliciting qualified contractors to perform Tier II environmental assessments for underground storage‑tank (UST) sites across the state. The work includes comprehensive field investigations, laboratory analyses of petroleum‑related contaminants, and the preparation of detailed reports that meet EPA and state regulatory standards. • Develop and submit Site‑Specific Work Plans (SSWPs) within 30 days of request, outlining drill‑plans, cost estimates, and safety procedures. • Conduct site surveys, install monitoring wells, perform soil and groundwater sampling, and execute required laboratory analyses (EPA Methods 1624, 8015, 8260, 8270, etc.). • Deliver a full Tier II Assessment Report (hard copy and electronic media) within approximately 120 days of SSWP approval, with an early‑completion incentive for faster delivery. • Provide all required health‑safety plans, standard operating procedures, and waste‑management documentation. • Maintain weekly field‑activity reports and bi‑weekly progress updates, and manage all invoicing and post‑award compliance requirements.

Budget estimate

$100,000 – $500,000

No contract value is disclosed. Based on typical Tier II assessments ($5‑$25 k per site) and the expectation that the contractor will handle multiple sites (potentially 20‑30 sites over the base year), a realistic revenue range would be roughly $100,000 to $500,000 for the first year. The low end assumes fewer sites or modest site complexity; the high end assumes a larger portfolio and higher‑complexity sites.
