HAPs Permit Compliance – Sandy Creek Energy Station, TX

As the project’s trusted emission testing consultant, Weston testing teams collaborating from the Auburn, West Chester, and Houston offices safely complete over 6 consecutive hazardous air pollutants (HAPs) and permit compliance demonstrations with no quality issues.

Weston was selected as an American Society for Testing and Materials International D7036-04 Standard Practice for Competence of Air Emission Testing Bodies qualified emission testing consultant to perform initial permit HAPs and criteria pollutants compliance testing at the Sandy Creek Energy Station in Reisel, Texas. The station was a newly-constructed, 900MW, sub-bituminous coal unit with extensive emission controls. Testing was required by more than 10 EPA test methods for comparison with low-level limits and consisted of an initial permit demonstration followed by 3 consecutive years of biannual testing requirements.

With the 3 years of demonstrations completed, the plant was able to operate under a reduced frequency basis beginning in 2015. During a number of the project events, Weston also performed relative accuracy test audits on plant continuous emission monitoring systems.

Final construction air permit negotiations for Sandy Creek Energy Station in Reisel, TX resulted in extremely low-level limits for a multitude of HAPs, individually and collectively, and included typical criterial pollutants. Because this was a controversial air permit, the stakeholders needed a trusted emission testing consultant to provide qualified test data for state and EPA submittal.

Weston creatively organized the project activities to meet scheduling demands and minimize time required by plant personnel and stakeholders in overseeing the test events. Additionally, because of a number of efficiencies we created in the project organization, the plant was able to reduce the amount of time required to operate at maximum capacity. This resulted in vast operational cost savings.
