Additional threatened and endangered species surveys will be undertaken <br />prior to additional surface disturbances as required by the respective surface <br />management agency. <br />The following control measures taken from the Final EIS dated February <br />2000 will be undertaken by the applicant: <br />1. In order to minimize or prevent impacts to breeding species of raptors <br />and their fledglings the applicant will survey specific forest habitats <br />prior to construction for evidence of raptor nesting activity. If any nest <br />sites are located, the timing and/or location of construction will be <br />modified to preclude any impacts to raptor nest sites. <br />2. In order to protect nest sites of sensitive avian species the applicant <br />will survey proposed development sites located in forest habitats for <br />snags. If snags are located, the location of surface disturbance will <br />be modified as necessary to avoid the loss of snags. <br />3. In order to maintain habitat effectiveness for big game, the applicant <br />will limit road construction. Necessary roads will be designed to <br />minimize disturbance to topsoil and vegetation and located to promote <br />effective road closure. New roads on Forest Service land will be <br />authorized by a special use permit. New temporary roads will be <br />reclaimed as soon as practicable. The roads will be obliterated using <br />all or a combination of recontouring, discing or ripping, placing <br />physical barriers at key points, seeding with a Forest Service <br />approved seed mix, signing and closures orders. Roads which are <br />reconstructed will be returned to their original contour so there will be <br />no net increase in accessibility to motorized traffic. <br />Regarding the Hubbard Creek ventilation fan: <br />Noise - The applicant purchased the Hubbard Creek Fan from <br />Spendrup Fan Co. Spendrup estimates the fan will produce a <br />sound pressure level of 97 dBA at a distance of 20 feet. Spendrup <br />further estimates the sound level can be reduced to about 82 dBA <br />by installing an outlet silencer and insulating the sides of the fan <br />PR -14 2.05-99 03/14 <br />
