Air Quality Permitting and Compliance

Comprehensive Services to Facilitate Clean Air Act Compliance

The NTH Air Quality Team offers exceptional regulatory expertise to a vast spectrum of industrial, institutional, municipal and utility clients. We have a thorough understanding of the industries that we serve and can offer complete air quality services including air permitting, dispersion modeling, compliance, and enforcement support. Our extensive technical and regulatory background, experience with many unique and complex projects, and our strong working relationship with the regulators, allows us to be your trusted advisor in air quality compliance for the markets we serve.

Air Permitting
Successfully navigating through the complex regulatory maze and securing necessary air permits in a timely fashion is paramount in keeping a project on track in order to begin construction and subsequent operation. NTH air quality staff has successfully prepared air permit applications for various clients that are technically sound, address necessary regulatory requirements, and provide operational flexibility. Through our permit negotiation efforts, we have assisted many clients in establishing permit conditions that are straightforward and do not impose unnecessary restrictions.

Dispersion Modeling
As ambient standards become more stringent, ambient impact analyses using dispersion modeling techniques are often the most significant portion of an air permitting project. NTH maintains experienced meteorologists that have a proven track record successfully providing air quality permitting solutions through modeling and qualitative analysis demonstrations. 

Regulatory Compliance Consulting
Keeping up with all of the latest regulations and can be daunting. NTH’s Air Quality Staff specializes in regulatory applicability and compliance strategies, and combines our knowledge of regulations and industry best practices to provide sound and practical guidance to our clients. We assist clients in:
  • Determining applicability of new regulations.
  • Summarizing all possible options for each client’s consideration.
  • Providing compliance recommendations in regard to costs, timing, future operations, and flexibility.
