Meadville, PA – The Pennsylvania Department of
Environmental Protection (DEP) and United Refining Company (United
Refining) announced that changes to United Refining’s Warren, PA,
facility have reduced sulfur dioxide emissions by 62% from 2011 levels
thanks to recent modifications. These modifications were initiated by
United Refining and have been memorialized in a Consent Order and
Agreement signed by both DEP and United Refining.
This agreement was part of Pennsylvania’s proposed revision to its State
Implementation Plan (SIP) designed to bring Conewango Township, Glade
Township and the City of Warren in Warren County into compliance with
federal air emissions standards. The area was previously designated as
nonattainment for the 2010 1-hour Federal National Ambient Air Quality
Standard for SO2. Short term exposure to SO2 has been linked to
respiratory conditions in humans.
DEP expects that it will be able to demonstrate that portions of Warren
County, specifically, Conewango Township, Glade Township and the City of
Warren, that are in the nonattainment area, will in attainment with
ambient air quality standard in 2018, following the required three years
of sampling. Following the reductions made by United Refining in 2015,
sulfur dioxide levels in the Warren Nonattainment Area have been well
below the standard of 75 parts per billion.
The proposed SIP revision, including the Consent Order and Agreement,
has been submitted to the Environmental Protection Agency and is
currently under review.
The COA allows the newly agreed limits to be legally enforceable, and
should United Refining’s emissions exceed any of the newly agreed upon
limits, there are specific stipulated penalties in place that will
continue daily until the air emissions are once again meeting the agreed
