11/5/2018 | In order to reduce surface disturbance, Confluence is permitting eight (8) additional wells on the Flaherty southwestern previously constructed well pad. This existing pad will also house production facilities for all sixteen (16) wells being permitted, after it is expanded as indicated by the location plats.
Confluence is also constructing a multi-well pad northeast of the current pad. This northeastern pad will house eight (8) wellheads only (i.e. no production facilities), which will minimize the disturbance area.

11/5/2018 | Leak Detection Plan: To ensure protection for the surface during construction, drilling, completions, and production, the location will be specifically constructed to contain any releases or spills. Secondary containment from any chemical spills or leaks will surround any trucks that carry, mix, or add chemicals to the flow stream as well as connections that could possibly leak fluid. Should any spill or release occur, every reasonable step will be taken to quickly remediate the disturbed area.
Once the wells are producing, a pumper will visit the location daily and visually inspect all tanks and fittings for leaks. Additionally, monthly documented SPCCP inspections will be conducted pursuant to 40 CFR §112.
