EPD* Officially Replaces PATH with PATH-2016# (Jan, 2016)

Since the release of the new air quality impact assessment model PATH-2016 (also known as “new PATH”) in Nov 2015, EPD requires that subsequent air quality impact assessments be evaluated via this new tool. A grace period until July 3rd, 2016 may be applicable for ongoing reports.

Air Quality Impact Assessment Model – One of the Most Computationally Intensive Components among EIA##Reports

The air quality impact assessment model, PATH-2016 is one of the most complex and time-consuming EIA applications. Air quality data preparation and long-term maintenance of the computing environments are extremely challenging.


Regardless of whether you are new to air quality impact assessment procedures or new to PATH-2016# system, you will face the challenges below. These make applying PATH-2016 in EIA## reports costly, risky and inefficient.

Adaptation – Quickly Learning New Models

Without advice from experts on PATH-2016 and PATH cluster, navigating the steep learning curve is difficult.

Equipment and Maintenance – Implementing and Administrating a High-end Cluster

Setting up, tuning, maintaining and administrating a PATH-efficient cluster needs trained IT experts.

Project Execution – Long Assessment Process

Prolonged input preparation and approval cycles result if staff have insufficient expertise in atmospheric science modelling and EPD* requirements.
