Odor Control

Regulatory Issues

Odor Contol

Today, more than ever, water and wastewater facilities must be prepared to deal with air quality issues.

Odor control has long been a major air quality issue for wastewater facilities.

The 1990 passage of the Clean Air Act Amendments has made Air Quality an issue to be addressed by both water and wastewater facilities. In particular those portions of the CAA which deal with the Risk Management Plans associated with the accidental release of toxic substances such as chorine.

Ongoing regulatory developments with respect to VOC and HAP emissions can and do impact capital and operational budgets for both water and wastewater facilities.

Air Quality Team

The Air Quality Team of Greeley and Hansen is comprised of Specialists who have successfully completed numerous odor control and air quality study and design projects throughout the United States. In the process, we have developed proven methods of determining the potential impact of an odor source or air pollutant/toxic emission on a community.

With the ever expanding base of regulators requirements and possible solutions, it is becoming difficult, if not impossible for any one individual to be completely knowledgeable of the full range of odor control technologies and air quality regulatory requirements. Further, it is even less likely that any one individual could have a broad base of experience in the design and implementation of such technologies and regulatory requirements.

Recognizing these limitations, Greeley and Hansen has embraced the team concept and has established a forum where our Air Quality Specialists through our national regional offices provide a pool of talent to share expertise and experience covering a broad range of odor control technologies and air quality regulatory requirements. By pooling our company wide talents in this manner, Greeley and Hansen can provide solutions and services which are unparalleled.
