RMS prepares the necessary deliverables following the CERCLA guidance including Preliminary Assessments, Site Inspections, Engineering Evaluation/Cost Analysis (EE/CA), Remedial Investigation/Feasibility Study (RI/FS), and Remedial Design/Remedial Action (RD/RA) documents. Regulatory agencies may adapt the process to address their needs, and RMS adapts the project scope to meet those needs.
