"Digging Into Your Permit" Workshop


Air permits can be difficult to follow and understand but the point of this workshop was to break a permit down into its most important parts. Staff from MCAQ talked specifically about monitoring, recordkeeping, notification, and reporting requirements plus provided resources that can help manage compliance. Gordon Miller, Air Quality Commission member, also gave a presentation on compliance from an industrial perspective.

Emissions Inventory Compliance Workshops - 3/31/2015 & 4/7/2015

MCAQ requires annual emission reporting from all permitted facilities by April 30 each year. In 2015, two emissions inventory workshops were held to assist permittees with preparing their facility's reports. The events focused on calculating emissions from volatile organic compound (VOC) and particulate matter (PM) emitting processes as well as how to comply with the triennial air toxics emission inventory.

"Get Fired Up About Air Quality Compliance" Combustion Source Workshop - 5/15/2014

Combustion sources like boilers and generators have many air quality requirements such as permitting, compliance with federal emission standards (GACTS), and review under the North Carolina Air Toxics Program.  MCAQ's 2014 workshop focused on those key requirements and included some tools to help boiler and generator owners stay on top of compliance.

Permitting 101 Workshop - 4/22/2012
Prior to installing a new source or modifying an existing source of regulated emissions, a facility must submit a permit application and receive an Air Quality Permit to Construct/Operate.

Stage I Vapor Recovery Workshop - 5/21/2012
Gasoline dispensing facilities receive gasoline products in underground storage tanks (UST's) from vapor tight truck tanks. Pipes and valves interconnecting the UST's and truck tank create a "closed loop" (i.e. Stage I gasoline vapor recovery system). The Stage I gasoline vapor recovery system collects 96% of the vapors that would have otherwise been emitted to the atmosphere and returns them to the bulk gasoline terminal for processing.
