The MacDonald Illig Environmental Group provides clients with compliance assistance in meeting the regulatory requirements for characterizing, storing and handling hazardous waste under the Resource Conservation and Recovery Act (RCRA). In addition to clarifying regulatory requirements, we assist facilities in preparation for RCRA inspections and if penalties have been assessed, we help facilities respond to USEPA and, where appropriate, challenge agency determinations and penalty assessments. We also help facilities respond to RCRA Corrective Action Environmental Indicators inspections that evaluate sites for migration of contaminated groundwater of exposure of humans to environmental contaminants.
