Tuesday, July 18th, 2017

Caltha LLP Project Summary

Project: Tank Farm Investigation
Client:
Agricultural Production Sector
Location(s):
South Dakota

Key Elements: Phase 2 Investigation, leaking tank, SPCC requirements

Overview: Caltha LLP was retained by a potential investor group to conduct a Phase 2 Limited Site Investigation (LSI) at this large farm site. During a Phase 1 Environmental Site Investigation, visual evidence of past leaks and spills were identified within the tank farm. Due to recent changes to Federal Spill Prevention, Control & Countermeasure (SPCC) rules which would require above ground tanks at agricultural facilities to comply with SPCC rule, the tank farm was expected to require upgrades. The key question was what cost impact would be expected during tank farm upgrade to address existing contamination. The results of the investigation provided clarity to the potential investors on the range of cost impacts.

Client: Regional Bank
Location(s): Minnesota

Key Elements: Soil and Groundwater Investigation

Overview:  Caltha LLP was retained by a prospective lender to conduct a soil and groundwater investigation for this gas station located in Minnetonka, Minnesota.
