Exit Strategy and Site Closure Northgate stands at the forefront of developing exit strategies for legacy sites. We work closely with our clients to develop strategies that manage future liabilities and enabling site closure. Northgate’s record of success with expedited closures is a testament to the strong relationships our staff have developed with the regulators over the years. Through preparation of strong technically defensible approaches, Northgate has gained significant trust with local, state and federal regulatory agencies. We work inclusively with regulators so that and they share in our project successes.
