Air Quality

Air Permitting

When it comes to air permitting, it seems that there is no end to the list of rules and regulations surrounding permits relating to EPA guidelines such as New Source Review Authorization, Title V, and more. Sage works with refineries to understand and adhere to these permits, offering the following services:


NSR is a preconstruction permitting program that serves two important purposes. First, it ensures that air quality is not significantly degraded from the addition of new and modified factories, industrial boilers and power plants. Second, the NSR program assures people that any large new or modified industrial source in their neighborhoods will be as clean as possible, and that advances in pollution control occur concurrently with industrial expansion. Sage's NSR offerings include:

Emission Reduction Credit (ERC) Documentation


Federal Operating (Title V) Permits (FOPs) are legally enforceable documents designed to improve compliance by clarifying requirements for facilities to control air pollution. These permits are issued to major sources and a limited number of minor sources (also known as “area” or “non-major” sources). Sage provides client support for all aspects of the Title V FOP program, including:

  • Regulatory applicability analysis and documentation
  • Initial issuance and revision permit application preparation
  • Deviation reporting and compliance certifications

Sage is also able to assist clients with review of major source status, establishment of federally enforceable limitations for minor source status where appropriate, compliance reviews, and management of compliance systems.


Our clients use Environmental Management Systems for a number of reasons. For some, certified programs require this level of organization. Others are simply driven by the concept of a cohesive system that provides structure, documentation and confidence that required tasks are being completed. Sage can help clients implement a purchased EMS, or may build a new system for a plant, depending on the goals and customization requirements. Either way, an EMS offers methods for defining, assigning responsibility, and tracking individual tasks for an entire environmental staff. This is especially useful for projects such as generating compliance deviations for title V reporting purposes.


With all that Sage can provide for our clients, it is not unusual for us to get pulled on site to work as a member of the team. When clients have a temporary gap in environmental staff, or are working on a special project that requires a larger team in the short term, they call Sage to supplement the people they currently have. This level of integration and tight relationship has been beneficial for many routine compliance projects.

Clients Speak Out

"My experience with Sage has been very positive... it starts with extremely well-rounded engineering professionals that have worked in manufacturing and seen a wide range of operational, permit, and enforcement issues. I depend on a number of key players within the Sage Environmental group, and in each person I have found a professional that has a strong "partner" perspective. Sage is truly concerned about having an impact on my company's bottom-line."
