Environmental Compliance

Terrawest Conservancy provides a variety of environmental compliance services which include: conducting compliance audits, preparing environmental compliance plans, preparing waste minimization and pollution prevention studies, and preparing facility toxic and hazardous waste management and operations plans and reports, such as Toxic Release Inventory (TRI) reporting. Terrawest compliance specialists work closely with clients to tailor a strategy for achieving compliance that meets corporate and operational needs.

Compliance Management Plans

Terrawest Conservancy will typically initiate compliance planning services with a general facility audit or inspection. Our team of compliance specialists review facility operations permits, plans, manifests, process documents, and the facility notification status.

Following the initial audit or inspection, a detailed site inspection is performed. During this site inspection process we evaluate compliance with Superfund Amendments and Reauthorization Act (SARA), Resource Conservation and Recovery Act (RCRA), the Clean Air Act (CAA), the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Clean Water Act (CWA), and the Toxic Substance Control Act (TSCA). ECA is also knowledgeable of DOT and OSHA requirements and regulations.

All of our compliance inspections are summarized in a facility inspection report which will provide a detailed account of individual compliance issues observed during our inspections. Our inspection reports are designed to be informative and accessible with all observations being accompanied by explanations of compliance issues, possible regulatory citations, and compliance solutions. Once the audit process is complete, Terrawest assists in the implementation of procedures, process changes, and strategies designed to achieve compliance with the required environmental, and OSHA regulations. We prioritize which violations need immediate attention versus those that are less likely to result in adverse safety conditions or incur regulatory fines. Our goal is to work together and develop a long term strategy for full compliance.

National Pollutant Discharge Elimination System (NPDES) Permitting

Terrawest Conservancy offers inspection services to ensure our clients’ compliance with Federal and state regulations regarding point source discharges of pollutants. This includes the National Pollutant Discharge Elimination System (NPDES), as well as state-specific regulation.

Once land disturbance is initiated, our NPDES Inspections regularly assess the condition of structural onsite controls, such as silt fencing, inlet protection, sediment basin function, etc., as well as non-structural controls such as hazardous materials housekeeping, training of personnel, placement of portable toilets, and the stabilization of disturbed areas, etc. Our team of Erosion and Sediment (E&S) control/NPDES inspectors have established a distinguished role above other inspection providers through sincere dedication to a higher level of oversight.

Phase IIs are typically conducted as a result of Recognized Environmental Conditions identified in a Phase I ESA.
