SOIL REMEDIATION AND DESIGN, SALT WATER DISPOSAL FACILITY, BURKE COUNTY, NORTH DAKOTA

  


After a salt water facility was severely damaged by fire in Burke County, ND, the site needed to be environmentally remediated. Contaminated and destroyed equipment was removed from location and soil samples were taken to determine the degree and extent of contamination. Cleanup of the site was hampered by inadequately designed site drainage resulting in large quantities of contaminated storm water which had to be handled and disposed. EA prepared engineering plans and specifications to reconstruct surface facilities including civil, mechanical, and electrical plans and specifications. The civil design plans corrected site drainage, addressed protection of a nearby wetland lake, and improved delivery truck access and safety for unloading. Plans documents included a grading plan, civil site layout, piping and instrumentation diagrams, piping layouts with a bill of materials, electrical area classification plans, electrical site layout, power distribution one-line diagram, panel schedules, and control system architecture drawings.

PRODUCED WATER TREATMENT AND DISCHARGE PERMITTING, CARBON COUNTY, MONTANA

  
 


At this conventional oil and gas production facility, EA staff characterized a 1,500 bbl/day produced water stream and evaluated management options. Underground injection, on-site evaporation, treatment, and surface discharge were considered. The owner/operator selected on-site treatment by reverse osmosis (RO) followed by surface discharge under a Montana Pollutant Discharge and Elimination System (MPDES) permit. EA staff provided technical support in design of the treatment process which included final chemical conditioning for pH and SAR. The treated water stream is surface discharged to an ephemeral drainage which intersects the Clarks Fork of the Yellowstone River one mile downstream. EA staff prepared and negotiated the MPDES application for an Individual Permit. EA also designed a lined surface impoundment/pit for on-site management of concentrated brine solution and prepared the pit permit application for processing by the Montana Board of Oil and Gas.

AIR PERMITTING FOR UNREGISTERED OIL PRODUCTION FACILITIES, FREMONT COUNTY, WYOMING

  
 


After receiving a notice of non-registration from the Wyoming Department of Environmental Quality (WDEQ) Air Quality Division (AQD), EA staff was asked to prepare air permit applications for two existing oil and gas production facilities in Fremont County, Wyoming. EA staff developed an inventory of fugitive and point source emissions from knockout vessels, sales oil tanks, produced water storage tanks, heater treaters, gas fired burners, truck unloading operations, and gas vents. EA staff coordinated sampling and analysis of produced gas, oil, and water under operating temperatures and pressures. An extended hydrocarbon analysis was performed on the samples and the data was input into air emission models to predict flashing emissions, and working, standing, and breathing losses. AQD approved emission models were used in the project (E&P Tank V2.0 & EPA Tanks).


EA staff met with the AQD and successfully presented a case for grandfathering one of the production facilities under previous WDEQ air quality regulations. EA submitted a full permit application for the second production facility demonstrating insignificant emissions and emission control requirements were subsequently waived.

INJECTION WELL AND SALT WATER DISPOSAL FACILITY DESIGN, MOUNTRAIL COUNTY, NORTH DAKOTA

  
 


EA prepared plans and specifications for a new salt water disposal facility in Mountrail Count, North Dakota. The commercial facility is designed to take produced water and frac flowback and process the fluids prior to injecting down a deep disposal well permitted for 5,000 BPD. Fluids are received by tanker truck, filtered to remove solids, and sent to a tank battery for further settling and processing. Oil separation is enhanced by a gunbarrel separator prior to fluids entering injection feed tanks.
 
EA provided project management, coordinated site surveying and geotechnical investigation, was the Engineer of Record for design, and facilitated procurement of major equipment, piping materials, and construction contractors. Mechanical equipment, including the injection pump, transfer pumps and filtration, is housed in a custom designed pumphouse with a separate electrical control and equipment room. The pumphouse is skid mounted, self-contained and designed for the cold weather environment of North Dakota.

BRINE INJECTION FACILITY MODERNIZATION, SHERIDAN COUNTY, MONTANA

  
 


EA was tasked with redesigning surface facilities for a commercial Class II UIC disposal well in Sheridan County, Montana. The facility, which had been in operation since the late 1980s, had NORM contaminated solids accumulated in tanks and surface impoundments. The tanks were cleaned and removed from the site and the surface impoundments remediated, wastes disposed according to State and Federal rules. EA was tasked with redesigning the facility to incorporate salvaged equipment such as the injection pump and existing injection line. Using SolidWorks, EA created a three dimensional model of the surface facilities including pipe routing, tanks, secondary containment, and civil improvement. From the model, engineering plans and procurement support materials were generated such as a detailed bill of materials for piping and nozzle schedules for tanks and gunbarrels.

UIC CLASS II INJECTION WELL PERMITTING, MOUNTRAIL COUNTY, NORTH DAKOTA

  
 


EA staff prepared an Application for Injection to convert an exploratory oil and gas well to a UIC Class II injection well. The permit was processed through the North Dakota Industrial Commission (NDIC) Oil and Gas Division and requested use of the well for commercial disposal of produced water (brine). The well and proposed facilities were located close to the shoreline of White Lake and the NDIC required detailed submittal of engineering plans prior to issuing an Order approving conversion. EA staff successfully resolved the concerns and a permit to convert was received.

STORM WATER POLLUTION PREVENTION PLAN (SWPPP) FOR EXPLORATION ACTIVITIES, UINTA COUNTY, WYOMING

  
 


EA staff prepared a Large Construction Storm Water Pollution Prevention Plan (SWPPP) for oil and gas exploration activities in southwest Wyoming. Activities covered under the SWPPP included construction of 5 miles of access roads, 15 well site pads, a new pipeline, and a gas processing facility. EA staff prepared the Notice of Intent submitted to the Wyoming Department of Environmental Quality (WDEQ) requesting field wide coverage for a project between 5 and 100 acres. The SWPPP was continuously revised to address changes in construction plans dictated by the exploration results. When part of the mineral assets were transferred during the second year of construction, A Notice of Transfer and Acceptance (NOTA) was filed with the WDEQ to facilitate compliance with program administrative requirements.

SPILL PREVENTION, CONTROL, AND COUNTERMEASURE PLANS FOR AN OIL PRODUCTION FACILITY, PARK COUNTY, WYOMING

  
 


EA staff prepared a Spill Prevention, Control and Countermeasure Plan (SPCC) for Windsor Energy’s Skull Creek operations. The Skull Creek Production Facilities include four well sites, gas collection flow line piping and a central gas treatment and compressor station. Each well site included one or more oil and water storage tanks and a gas treatment skid and several surface impoundments. Including a pipeline drip tank, well site storage, and the compressor station, the total oil storage capacity of the facility was 170,000 gallons. EA Staff certified the SPCC Plan as meeting 40 CFR Part 112 requirements for an on-shore production facility.

DESIGN, SITE LOCATION APPROVAL AND GROUNDWATER DISCHARGE PERMITTING FOR ON-SITE WASTEWATER TREATMENT FACILITY, LAS ANIMAS, COLORADO

  
 


EA staff prepared documents and provided technical and managerial oversight to receive Site Location and Design approval from the Colorado Department of Public Health and Environment (CDPHE). The approval was to construct and operate a large capacity treatment system to handle domestic wastewaters from a remote administrative and maintenance facility. The facility was constructed by Pioneer Natural Resources to support their exploration and production activities in the Raton Basin Natural Gas Field. EA Staff worked with CDPHE and the 208 Planning Commission for Site Location Approval and successfully permitted groundwater discharge of treated effluent. EA staff provided the environmental permitting and designed the treatment system which handled 7,000 gpd. The design was based on enhanced biological treatment utilizing an anoxic tank and a recirculating filter (packed bed) system. Final dispersal was via subsurface drip irrigation above an engineered drain field.
