Highway Vehicles (OHVs), from using them. Signs identifying the <br />road closure shall be placed at the barricades. <br />• To prevent mortality of GBCT due to pumping from the East Fork of <br />Terror Creek, the conservation measures are defined as: pumping <br />during the June and July period would require the use of a <br />screened pump intake, with a maximum'/ inch size mesh. For the <br />August through September period, when GBCT fry would be <br />present in the stream, pump intakes would be screened with no <br />larger than 1/1 6th mesh screen. The screen would not be confined <br />to just the pump intake, but must cover a larger area, such as a <br />cylinder or box design which has at least 5 times the surface area <br />of the pump intake. Bowie must submit the final design for this <br />screening fixture to the USFS and BLM fisheries biologists for their <br />approval. <br />• During the June through September period, if the flows in East <br />Terror Creek drop below the ten year mean monthly flow for <br />October (1.0 cfs), lessee will not pump water from the East Fork of <br />Terror Creek. <br />• To prevent impacts to GBCT fry and fingerlings, pumping would <br />not take place during the base flow (low flow) periods of the year — <br />October through March. <br />• If there are existing roads or disturbance features within the 200 - <br />foot buffer along GBCT habitat streams, then no additional surface <br />disturbance will be permitted within those areas. Maintenance of <br />roads or other existing features must remain within the existing <br />road prism or footprint of the feature being maintained. The <br />operator shall not store equipment, machinery, or construction <br />materials in any locations that are 200 feet or less from the riparian <br />zones of the streams within the Terror Creek watershed. <br />No vegetation will be removed from the riparian zone of the <br />streams in the Terror Creek watershed. <br />During construction or maintenance activities in proximity to the <br />200 -foot riparian buffer zone, the edge of the buffer zone shall be <br />marked for avoidance by construction equipment and activities. <br />Within the Terror Creek watershed, only fresh water, free of <br />chemicals or other contaminants, may be used for dust abatement <br />activities. <br />PR -14 2.05-102 03/14 <br />
