SUBJECT: UPDATE ON PAD SITES REPORTED WITH HIGHER EMISSIONS
WITHIN THE NATURAL GAS AIR QUALITY STUDY — INTERIM
REPORT PREPARED BY EASTERN RESEARCH GROUP, INC.
The purpose of this Informal Report is to provide an update about the pad sites reported with
higher emissions in the Natural Gas Air Quality Study — Interim Report prepared by Eastern
Research Group, Inc. (ERG).
The Interim Report identified two pad sites with higher point source emissions: 2299 Mercado
Drive and 11398 West Freeway. The site operators have taken the opportunity to review site
operations. Additionally, the Texas Commission on Environmental Quality (TCEQ) has visited
both sites to perform Compliance Investigations. TCEQ is now reviewing emissions inventory
data, Interim Report data, and observed site operating conditions. These Compliance
Investigations will culminate in a Final Compliance Report to be issued and made public for each
site. The Final Compliance Reports are expected to be finalized by TCEQ by the end of April.
ERG has completed the
revisits on each site. In
general site operating
conditions were similar during
the February 2011 visits as
they were during the
September 2010 visits.
ERG has found an error in
their emission calculation for
2299 Mercado Drive site. The
revised preliminary findings
indicate annual volatile organic
compound (VOC) emissions of
0.3535 tons /year instead of the
previously reported 103.78
tons /year. The error was
found in the spreadsheet used
to calculate the emissions.
The 11398 West Freeway site
had no such error. Additionally, the 2299 Mercado Avenue site should have been listed with a "B"
flag on the Preliminary Results Table 1. The "B" flag means that overall point source emissions
at the site were preliminarily calculated with only a chemical profile from a tank emission.
ERG has taken measures to put in place more rigorous data control and review processes. All
results in the Interim Report are preliminary and as such are subject to change in the Final
Report.
