1.1.1 Incident Category
Emergency Response / CERCLA
1.1.2 Site Description
The site is located at Rock Creek Gas Plant located at the west end of 10th Street in Borger, Hutchinson County, TX. The area surrounding the plant to the east consist of residential homes and open fields to the west. The plant processes natural gas from fields located near Dumas, Tx. Rock Creek Gas Plant is owned and operated by DCP Midstream.
1.1.2.1 Location
Site is located at 1000 West 10th Street, Borger, Texas 79007.
Latitude: 35* 40' 23.5" N
Longitude: 101* 24' 39.4" W
1.1.2.2 Description of Threat
Approximately 100 bbls of monoethanolamine (MEA) were released due to an equipment malfunction at the plant amine contact unit. The corrosive MEA migrated to the southeast and off-site via the plant outfall into an unnamed creek which flows to the west and north circling the facility property and into Rock Creek, which flows into the Canadian River. The incident caused a fish kill impacted small minows, small brim, and small catfish.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
The potentially responsible party, PRP, bermed the creek at the further-most section of impacted creek, approximately one creek mile from release point. The slow moving creeks vary in width from a few feet to approximately 10 feet and depth from inches to a few feet.
As a heavier than water substance, MEA has pooled in pockets of the creeks. The PRP also installed a rock berm approximately one half mile from release point to further minimize migration. Several fish have been observed impacted from the incident, from minows to small brim and catfish, as well as turtles.

2.1.1 Narrative
On December 27, 2013 EPA received notification (NRC#1069539) of a release of approximately 100 bbl of monoethanolamine (MEA) from the Rock Creek Gas Plant located in Borger, Hutchinson County, TX.
At 1300 hours OSC Adam Adams activated START and began mobilization. Facility representatives reported that at 2215 on December 26, 2013 workers discovered a leak in the MEA contact unit/recirculation system. After gauging the MEA recovery tanks, workers determined that approximately 100 bbl were missing. The released MEA flowed downgradient following stormwater runoff pathways offsite and entered a tributary of Rock Creek.
2.1.2 Response Actions to Date
EPA team arived on site at approximately 1800 and met with DCP Midstream representatives (PRP). The PRP reported that after discovering the release, plant workers constructed two earthen dams at approximately .25 and .75 miles from the point the MEA entered the tributary. Plant workers reported seeing dead fish and a dark tint to the water along the damed portion of the tributary. Five samples were taken to determine concentrations of the contamination along the release pathway.
PRP has staged three frac tanks at the recovery location to evacuate the bermed portion of the creek and flush the creeks with fresh water.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
The PRP at this time, is DCP Midstream.

|
|
2.2.1 Anticipated Activities
PRP will continue to contain all creek fluids at the downstream earthen berm and evacuate the creek upstream to enable successful flushing with fresh water.
Final disposition of wastes will be discussed with the PRP and TCEQ.
2.2.1.1 Planned Response Activities
PRP will utilize small pumps to move pooled areas of the creeks downstream to the recovery location.
PRP will evacuate the bermed portion of the creeks and flush the drainage path and creek with fresh water.
PRP will provide analytical results from the sampling event to EPA.
PRP will provide daily sitreps to EPA.
2.2.1.2 Next Steps
TCEQ and TxRRC will be on site on Monday, 12/30/13 to assess the incident.
