BLM Required Conservation Measures: Appendix A • In order to insure that BMPs relating to the control of sediment from disturbed sites are in place, and functional, Bowie will, on a monthly basis from May through August, use an independent contractor to inspect Bowie's well pad sites and access roads within the Terror Creek watershed. The independent contractor will contact Bowie and the BLM Uncompahgre Field Office (970- 240 - 5300), within two business days of discovering sediment control measures that are missing or non - functional. Bowie will have three business days to correct the problem. Ineffective measures would be redesigned and replaced after consultation with BLM. For each year that Bowie operates under this BA, Bowie shall submit the compiled monthly inspection reports to BLM Uncompahgre Field Office 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. • In order to prevent increased risk of sediment being generated as a result of pumping related disturbance, pumping from East Terror Creek would not take place until after the April and May peak runoff period has past. Therefore, pumping from East Terror Creek would not begin until June. The AO may grant an exception that would allow pumping in May if runoff flows have dropped to the normal mean monthly levels for June (6.9 cfs) and USFWS has concurred via informal consultation. • 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 \4 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 BLM Western Slope fisheries biologist, Tom Fresques (970- 876 -9078; tlfresqu @blm.gov), for his 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), Bowie 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. • There will be no new surface disturbing activities within 200 feet of any occupied greenback cutthroat trout habitat, as measured from the normal high water mark. • 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.
