Soil and Groundwater Investigations / Remediations and Facility Unit Closures

State and federal regulations dictate specific steps to achieve proper closure of decomissioned process units and waste storage, treatment, and disposal units when their operations cease. The Texas Risk Reduction Program (TRRP) applies to closure and remediation activities, so companies in Texas must determine how to combine RCRA closure requirements with TRRP requirements.
