Air Quality Permitting

Permitting With a Purpose

Air permitting, NSR, Title V, and the maze of other EPA air quality requirements is the core business of Sage ATC.

 Obtaining a New Source Review (NSR) air quality permit is the largest challenge to meeting the capital project start of construction schedule.  Navigating the maze of NSR complexities to produce a permit that allows clients to operate their plant efficiently, while minimizing redundant record-keeping and reporting, has been the cornerstone of our business for almost two decades.  With an in-depth understanding of our clients’ processes, regulatory requirements, and the permitting options available, Sage ATC will craft a permit that allows clients to minimize their regulatory burden while optimizing plant production.

 We understand what a clear permitting pathway looks like.  Whether planning a multi-billion dollar expansion or a simple modification, knowing how to efficiently navigate the new challenges associated with the air permitting process will determine the success or failure of the project.

Our breadth of permitting experience combined with a close working relationship with Agency permit writers, results in unmatched successes with even the most challenging projects.

We Understand Our Clients’ Permitting Needs:

Our subject matter permit experts put a lifetime of experience into crafting a permit designed not only to provide our clients with certainty on a start of construction schedule, but also to negotiate a permit to meet their operational needs after issuance. We know the rules, we understand the options, and take on the most complex permitting challenges with a wealth of benchmarking knowledge to bring our clients not only a permit to construct and operate but also a permit strategy consistent with their business plan.

We Have Superior Relationships with Agency Permit Writers:

Sage ATC permit experts work with agency staff on a daily basis to deliver a technically superior permit application that anticipates and addresses agency priorities. We know the agency “hotspots” and deliver our permit applications with knowledgeable benchmarking of previously approved BACT, emission calculation techniques, and permit terms. Hitting the mark on the first try means shortened review cycles and issuance of a permit on a condensed timeline.

Superior Permitting Toolbox:

Our permitting experts provide clients with a realistic evaluation of permit options, timing considerations, and overall philosophy for establishing and executing a strategic permitting plan for their organization. We have extensive experience using complex options under the NSR rules. We routinely consider the application of advanced permit concepts including Flexible and Plantwide Applicability Limit (PAL) permitting, and using demand growth are able to accommodate strategies to avoid Federal PSD and Nonattainment Permit requirements. We conduct exhaustive benchmarking to make sure that the Best Available Control Technology options and the most favorable testing, recordkeeping, and reporting requirements are available to our clients. We know the options and work tirelessly to build the best possible permit.
