Environmental Compliance

HSW’s experienced and integrated permitting and compliance services help our clients achieve timely and cost-effective approvals.  We work closely with our clients and with regulators to identify appropriate means of addressing regulatory and permitting requirements for a broad array of jurisdictions and sectors. We have an excellent record of satisfying the simultaneous objectives to proponents, regulators, stakeholders and communities.  Depending on a project’s complexity, intermittent project status meetings may be conducted at pre-determined milestones throughout the project’s duration to keep the project on track with established goals to ensure a successful outcome.

HSW regulatory experts have a detailed knowledge of the myriad of regulations, policies, and guidance associated with hazardous waste identification, management, and corrective action. In a number of cases, overly conservative regulatory interpretations had been used by organizations, at great cost. Accordingly, we have prepared thorough regulatory evaluations of our client’s wastes and contaminated media for discussion with the regulators, often resulting in de-regulation of the materials and considerable cost savings for our clients.  Moreover, our waste compliance audits have often revealed compliance issues that can be mitigated prior to regulatory violations, also resulting in significant value of our services.
