HARRISBURG — The Department of Environmental Protection has fined Chesapeake Appalachia LLC a total of $565,000 in civil penalties and reimbursement costs for erosion and sediment control violations, wetland encroachment violations and an April 2011 well control incident.
DEP fined Chesapeake $215,000 for a March 2011 incident in West Branch Township, Potter County. In late February and early March, heavy rain caused significant erosion to an access road and Chesapeake’s Beech Flats gas well pad, both of which lacked sufficient controls in place to prevent the run-off.
As a result, significant amounts of sediment entered the Right Branch of Wetmore Run, a high-quality stream.
An inspection found that accelerated erosion had occurred at several spots on the access road and the well pad because the operator failed to construct adequate controls to prevent the run-off of sediment. The sediment traveled downstream and impacted Galeton Borough Authority’s water treatment filters.
Chesapeake has since paid $190,000 to the authority to repair and upgrade the water supply facility and has made assurances it will reimburse the authority any additional costs associated with this incident.
DEP issued a compliance order that required Chesapeake to cease all activity at the site that would disturb earth. Chesapeake was also ordered to implement additional measures designed to lessen environmental impact and submit a revised erosion and sediment control plan.
Soon after that, the company installed silt fences, silt socks, gravel surfacing of the access road and a stormwater capture ditch, and it submitted the revised plan. Follow-up inspections determined that the violations were corrected.
In addition, Chesapeake paid $190,000 as part of a consent order and agreement after the operator lost control of a well head during hydraulic fracturing of the Atgas 2H Well in Leroy Township, Bradford County, on April 19.
Fluids from the well mixed with rainwater and entered a nearby unnamed tributary to Towanda Creek and Towanda Creek itself. On April 20, DEP detected levels of total dissolved solids, chlorides and barium that were higher than background levels at the mouth of the tributary, where it enters Towanda Creek.
Subsequent testing further downstream showed these levels returned to normal background levels. Chesapeake took two days to stop the flow from the well and four days beyond that to bring the well fully under control.
At DEP’s request, Chesapeake suspended completion activities at well sites across the state for approximately three weeks while assessing its equipment’s integrity, containment mechanisms and procedures.
Chesapeake’s payment includes a $67,000 reimbursement for costs associated with the agency’s response.
The company must also conduct further testing, using an independent laboratory, of five groundwater monitoring wells from the surrounding area to ensure there were no impacts to groundwater from the release.
North Towanda Township. In connection with a third site, DEP fined Chesapeake $160,000 as part of a consent order and agreement resulting from violations in 2010 of impacting a wetland and allowing sediment to enter Sugar Creek in North Towanda Township, Bradford County.
Part of a well pad built in the wetland was constructed with extremely high, steep slopes which, after significant precipitation, caused additional sediment to slide further into the wetland and the nearby stream.
DEP issued a notice of violation for encroaching on wetlands without a permit and failing to implement best management practices. A follow-up meeting also directed Chesapeake to develop a remediation plan. By constructing the well pad in that way, the company filled a third of an acre of wetlands without authorization.
There were additional temporary impacts to the wetland through erosion and tree clearing and in October 2010, heavy rains caused the middle portion of the pad’s fill slope to fail and sediment to enter Sugar Creek and an unnamed tributary, as well as further impact the nearby forested wetland.
In addition to paying the penalty, the company has removed the fill from the impacted wetland and must construct 2.55 acres of replacement wetlands. The company is also required to submit regular, detailed wetlands restoration monitoring reports.
Chesapeake’s actions constituted violations of the Oil and Gas Act, Clean Streams Law and the Dam Safety and Encroachments Act.
