A-12 • In order to ensure that BMPs relating to the control of sediment from disturbed sites are in place and functional, lessee shall, during major runoff periods, use an independent contractor to inspect the lessee’s well pad sites and access roads within the Terror Creek watershed. The independent contractor shall contact lessee, USFS, and the BLM (970-240-5300), within two business days of discovering sediment control measures that are missing or non-functional. Lessee will have three business days to correct the problem. Ineffective measures would be redesigned and replaced after consultation with USFS and BLM. For each year that lessee operates under this BA, lessee shall submit the compiled monthly inspection reports to BLM UFO by September 30. In the event new sediment control methods are identified or current practices are not working as intended, adaptive management will be used to implement methods that are effective at eliminating offsite movement of soils and sedimentation into resident streams. • At any time during drilling activities, until successful reclamation or continuing into the future, the point of access to temporary roads shall be blocked with gates to prevent vehicles, including Off-Highway Vehicles (OHVs), from using them. Signs identifying the road closure shall be placed at the barricades. • To prevent mortality of GBCT due to pumping from the East Fork of Terror Creek, the conservation measures are defined as: pumping during the June and July period would require the use of a screened pump intake, with a maximum ¼ inch size mesh. For the August through September period, when GBCT fry would be present in the stream, pump intakes would be screened with no larger than 1/16th mesh screen. The screen would not be confined to just the pump intake, but must cover a larger area, such as a cylinder or box design which has at least 5 times the surface area of the pump intake. Bowie must submit the final design for this screening fixture to the USFS and BLM fisheries biologists for their approval. • During the June through September period, if the flows in East Terror Creek drop below the ten year mean monthly flow for October (1.0 cfs), lessee will not pump water from the East Fork of Terror Creek. • To prevent impacts to GBCT fry and fingerlings, pumping would not take place during the base flow (low flow) periods of the year – October through March. • If there are existing roads or disturbance features within the 200-foot buffer along GBCT habitat streams, then no additional surface disturbance will be permitted within those areas. Maintenance of roads or other existing features must remain within the existing road prism or footprint of the feature being maintained. • The operator shall not store equipment, machinery, or construction materials in any locations that are 200 feet or less from the riparian zones of the streams within the Terror Creek watershed. • No vegetation will be removed from the riparian zone of the streams in the Terror Creek watershed.
