Colorado State University owns and operates numerous stationary sources of air emissions. These include sources like boilers, emergency generators, incinerators, breweries, landscaping equipment, parts cleaners, a paint booth, and the compost facility. CSU is subject to State and Federal air regulations and has received several air permits from the Colorado Department of Public Health and Environment (CDPHE). Three areas are subject to umbrella air permits called Title V Operating Permits. These permits encompass many individual sources in one area, and describe emission limitations or conditions for each stationary source in that area. The three areas subject to Title V Operating Permits are:

• Main and South Campuses
• Foothills Campus
• Powerhouse Energy Campus

In addition, an air emission source subject to a specific air permit exists at one outlying campus – the pathological incinerator at the Arkansas Valley Research Center.

All permits have recordkeeping, reporting, and renewal requirements. Engineers and specialists in the ECC group perform or oversee air regulatory compliance tasks including:

• Calculating emission amounts for select sources on a monthly or semiannual basis
• Providing semiannual and annual reports to CDPHE
• Preparing Air Pollution Emission Notices and renewals as needed
• Tracking and compiling opacity measurement data
• Commissioning and overseeing air dispersion modeling as required
• Greenhouse gas reporting to US EPA and CDPHE annually
• Reviewing the State’s Environmental Justice requirements and data during permit renewal activities

CSU is also subject to air regulations governing Ozone Depleting Substances, also referred to as CFC regulations. CSU tracks and documents repairs to units containing regulated refrigerants.
