2019 EMISSIONS INVENTORY RESPONSE
CITY OF DENTON LANDFILL
Project Understanding
In an effort to maintain compliance with all state air quality regulations, the City of
Denton has requested that Weaver Consultants Group, LLC (WCG) submit a
proposal for preparing the 2019 Emissions Inventory (EI) for the City of Denton
Landfill.
Task – Prepare Emissions Inventory Response
WCG will prepare the 2019 EI calculations for the site using the information
provided by the site. The landfill emission calculations will be prepared utilizing the
available site-specific information and the U.S. EPA’s Landfill Gas Emissions Model
(Model). The Model will be used to estimate the landfill’s actual emissions of volatile
organic compounds (VOCs) and hazardous air pollutants (HAPs). Emission
calculations will be prepared for the particulate matter (PM2.5, PM10, and PM30)
emissions generated from vehicles traveling on unpaved roads and earthmoving
operations at the site by utilizing the EPA’s Compilation of Air Pollutant Emission
Factors (AP-42). The flare emissions will be calculated using the site-specific
information and manufacturer emission factors or AP-42 emissions factors.
Emission calculations will also be prepared for the storage tanks, solidification
operations, emergency generator, and surface coating operations.
In addition, WCG will prepare the EI forms with the calculated emission totals and
other site information to be submitted to the TCEQ. Upon completion of emission
calculations, WCG will submit electronically in STEERS the calculated emission
totals and other site information as required by the TCEQ regulations.
Project Budget
The estimated cost for this project is shown below with all services being provided
on a lump sum basis.
