Project - Flint, Michigan Auto Plant- Automotive Processing

Capacity: 100 kpph
An Automotive Power Plant owns and operates three boilers in the powerhouse at their 902 E. Leith Street facility in Flint, Michigan. All three boilers combust exclusively pipeline quality natural gas to generate steam that is used at the site for process and space heating purposes. All three boilers have a rated capacity of 100,000 lbs per hour steam output. The exhaust gas stream is discharged to the atmosphere from each boiler through a separate stack.

Boiler #1 and Boiler #2 are subject to New Source Performance Standards (NSPS) promulgated under U.S. 40 CFR Part 60, Subpart Db. These regulations specify emission limitations for nitrogen oxides. The regulations require installation, calibration, maintenance, and operation of an emissions monitoring system for documentation and reporting of operating data and nitrogen oxides emission rates. Emissions from these two boilers are monitored using a predictive emissions monitoring system (PEMS). 40 CFR Part 60, Subpart Db requires development and implementation of this QA plan.
