ETS was commissioned to assist a client in violation of
agency permitted limits for particulates, fluorides and NOx. The ETS work
scope was to review the client’s overall compliance status and recommend a
comprehensive program to gain compliance. In addition the client requested
that ETS provide continued interface with the agency throughout the
program.
An approach was developed along with a schedule to meet
compliance and was presented to the DEQ. The plan was scrutinized by the
agency and subsequently accepted. ETS was then requested to assist in
implementation of the recommended approach, and providing continuing
monitoring, data acquisition and reporting as required by the agency.
ETS was recently awarded a contract from a west coast DEQ
to assist the agency in identifying the Best Available Retrofit Control
Technologies (BARCT) suitable for installation within the 2011-2014 time
frame to help the district attain PM2.5 ambient air quality
standards. The area is classified as “non-attainment” for PM2.5
and must meet National Ambient Air Quality Standards (NAAQS) by 2015.
Industries within the district of concern included several oil refineries,
glass manufacturing, and cement manufacturing. The project involved
visiting the facilities, acquiring and reviewing pertinent operational and
emission data, evaluating suitable control technologies for each facility
and predicting their impacts on SOx (a key pre-curser of sulfates and one
of the principal components of PM2.5 ) and PM2.5.
Technical and cost proposals were requested from a short list of vendors,
along with their estimates for equipment delivery and installation. All
information and analysis, vendor proposals and delivery schedules along
with ETS conclusions and recommendations has been documented in an ETS
report and utilized by the agency.
An ETS client was required to install and maintain a NOx
continuous monitoring system (CEMS) as a requirement of the firms' permit
to operate the facilities industrial boiler. The regulation stipulated
that the client submit quarterly reports to the agency. These reports were
to include average hourly NOx emission rates as well as a 30 day rolling
average of these emission rates. The client hired ETS to install and
maintain the CEMs system, and conduct all necessary calibration and
accuracy assessments. In addition the ETS work scope also included all
data acquisition, analysis, and reporting. In this project ETS submitted
the quarterly reports to the client for his subsequent submittal to the
agency. The project ran for over eight years.

assistance projects are presented in the case history section.
