US EPA Montana Office 10 W. 15th St., Ste.3200 Helena, Montana 59626 1-800-457-2690 Status: The Milltown Reservoir cleanup project is going well and is on schedule for dam removal in spring 2008. Due to recent rains, the turbidity level measured on 2/18/07 at Turah was 20 NTUs and 15 NTUs below the dam. The trigger level for additional sampling is 12 NTUs; therefore, Envirocon stepped up its surface water sampling program. No Best Management Practices (BMP) evaluation (to adjust site activities) was necessary because the majority of turbidity originated upstream of the project area. Turbidity levels have now dropped to below 6 NTUs. Monitoring information is available: ftp://milltown.envirocon.com Currently: • Construction continues on the Clark Fork River flood berm. Upon completion, con- struction of the flood berm on the Blackfoot River will begin. All flood berms will be finished by April 2007. • Construction continues on the on-site haul road at the base of 1-90. • Soils gradation work continues. This work is needed to ensure that riprap and soils used on site are appropriate for construction of the bypass channel, haul roads, flood berms, etc. • Workers continue to screen rock out of the borrow area soils. The rock will be used as riprap and the finer materials for berms and haul roads on site. • Envirocon continues to prepare an area for more permanent offices. The US Army Corps of Engineers (USACE) will be EPA's construction oversight representative and will have office space on site. • Preparation begins this week for the new site entrance off Rustic Road. Envirocon will also be adding a truck scale to this location. Upcoming: • A riprap source has been identified. Material will come from the east on 1-90 and will be brought onto the site via the new entrance off Rustic Road (next to the Montana Rail Link log unloading area). Riprap hauling should begin in the next week or so and continue through April 2007. We expect approximately 20-30 truckloads per day during this time. Signs are being posted — the speed limit on Rustic Road and High- way 210 E (near the project area) will be reduced to 45 mph during active hauling.

Stop by to talk, ask ques- tions or to simply say "hi!" Pedestrian Trail Open House Last week Missoula County held an Open House to discuss plans for a pedestrian trail along Highway 210 East. The focus of the Open House was the part of the trail proposed from the Banner School east to the Piltzville Fire Station and the turn- off to Rustic Road. Construction of this portion is scheduled to begin this summer and be complete by August 2007. Approximately 150 people attended the Open House and provided a lot of good in- put that will be considered as the trail de- sign is finalized. Those attending were able to view designs for the three distinct segments of the proposed pedestrian trail: 1) Concrete trail with AD A-accessible curbs from the Banner School to the high- way bridge; 2) the bridge with a widened pedestrian crossing; and 3) the asphalt trail from the bridge to the Piltzville Fire Station and Rustic Road. This portion of the trail will address the safety concerns associated with construc- tion of the rail line behind the Banner School and periodic hauling of materials along Hwy. 210 East to and from the site. The trail will later be extended along Highway 210 E and Rustic Road to the Turah interchange. Missoula County plans at least two additional public meetings. EPA has provided $500.000 for trail con- struction; additional funding will come from the federal transportation bill appropriation to Missoula County to implement the 2005 Conceptual Redevelopment Plan for the Milltown Reservoir area.

Uneven ice on the Blackfoot River means unsafe — yes, dangerous — ice conditions. Please remind family and friends to stay off the ice and out of the areas closed to the public during the Milltown Reservoir cleanup. Thank you! Be safe! ------- |
