The Arkansas Department of Environmental Quality (“ADEQ”) and Enable Mississippi River Transmission, LLC, (“Enable”) entered into a May 17th Consent Administrative Order (“CAO”) addressing alleged violations of an air permit.
The CAO provides that Enable owns and operates a natural gas compressor station (“Station”) in Ashley County, Arkansas.
The Station is stated to be covered by two Air Operating Permits. One has since been voided.
Enable is stated to have submitted a Title V Semi-Annual Monitoring Report (“SAM”) for the reporting period of October 1, 2015, through September 30, 2016. Such report is stated to have indicated one period of downtime in which the temperature data recorder for SN-06 failed to maintain the temperature records for the exhaust gas temperature at SN-06. It also is stated to have reported one period of downtime at the temperature data recorder for SN-07. These alleged failures are stated to violate General Provision 6 of Permits R7 and R8.
A SAM for a subsequent reporting period was submitted to ADEQ which is stated to have indicated the same two periods of temperature data recorder downtime.
The CAO provides that Enable submitted a SAM on October 13, 2017, for the reporting period of October 1, 2016 through September 30, 2017. This SAM is stated to have reported one period of temperature data recorder downtime in which the temperature records for SN-07 were not maintained during the reporting period, violating General Provision 6 of Permits R7 and R8.
Enable is stated to have submitted a response to ADEQ which stated in part that monitoring of the inlet catalyst temperature was conducted during the periods of downtime by the programmable logic controller although one-hour measurements of catalyst inlet temperature were not available. To prevent further occurrences Enable stated that the Station has identified and is planning to upgrade the Continuous Parameter Monitoring System (“CPMS”) at the Station.
Enable began installing the CPMS upgrades at the Station on January 31, 2019.
Enable neither admits nor denies the factual and legal allegations contained in the CAO.
A civil penalty of $937.50 is assessed.
