Economic Downturn Creates New Business Opportunities for Lafarge

1. Economic Downturn Creates New Business Opportunities for Lafarge Nancy Musgrove Windward Environmental LLC

2. Lafarge Seattle Facility • Lafarge – one of the world’s largest manufacturers of Portland cement • Seattle plant – in operation since 1967 • Capacity to produce 490,000 tons cement per year • Production based on single wet-process kiln • Water demand met, in part, by capture and reuse of on-site stormwater

4. Economic Downturn Changed Plant Operations • Mothballed wet kiln in 2010 • Ceased clinker production • Continued dry product • Grinding, mixing, and shipping • Re-engineered stormwater system for greater capacity/more frequent discharges

5. Available Facility Assets • Existing infrastructure: • 1,100-ft wharf • Rail-mounted electric crane with 10-CY clamshell bucket • 1.1M-gal. (5,600-CY) concrete vault • Rail spur • Trained personnel • Location in industrial corridor on Lower Duwamish Waterway

6. Waterfront Crane and Wharf

7. Wharf-side Vault

8. Opportunity to Serve as Transload Facility

9. Superfund Early Actions in Lower Duwamish Waterway • Superfund site in Seattle – Proposed Plan due January 2013 • Six early action sites identified, including Slip 4 • Early action selected by EPA – dredging and capping of Slip 4 • Remove and dispose of 14,000 tons of debris, PCB-contaminated sediment, and bank soil

11. Lafarge Qualifications as Transloader • Within 1.8 river miles of Slip 4 • Infrastructure needed only minor modifications • Large equipment, experience and capacity to rehandle and ship bulk material • Flexible stormwater management • Easily implemented operational and structural BMPs • State’s willingness to quickly modify NPDES permit

12. Facility Preparation • Updated SWPPP • Modified NPDES permit • Physically isolated transloading area runoff from plant stormwater system • Replumbed two mothballed slurry tanks to replace concrete stormwater vault

13. EPA, State and City Support • Regulators and project managers reviewed: • Proposed BMPs (e.g., routine housekeeping, spill response, etc.) • Remedial action work plan transloading elements • Environmental compliance program • Health and safety program • Few modifications were required

14. Performance • Existing plant infrastructure handled the transload materials safely and without incident: • All transload area runoff captured and shipped with dredged material • New BMPs prevented transload project runoff from entering the plant’s stormwater system • Facility/equipment easily decontaminated after project completion

16. Benefits to Community • Lower carbon footprint than would have other alternatives: • Rail transfer eliminated diesel emissions from truck transport • Location minimized barge travel • Electric crane eliminated secondary emissions • Minimized impacts to surrounding neighborhood

17. Benefits to Slip 4 Project • Avoided construction/decommissioning of a temporary transloading facility • Lafarge’s transload capacity prevented project bottlenecks • Use of Lafarge site reduced chance of spills during dredge material handling

18. Benefits to Lafarge • Added new business, increased equipment and staff utilization • Positioned to support other cleanup projects in the region • Containment vault and transloading equipment can be repurposed quickly • Vault can be returned to stormwater service • New BMPs and other procedures are easily implemented and adaptable

19. Summary of TransloadingProject Benefits • Economic: • Employees • Lafarge • Project (Slip 4) • Environmental and public health: • Reduced impacts of remediation • Community health • Regulatory policy goals: • Green benefits • Social justice

20. Keys to Success • Flexibility • Openness • Creativity • Cooperation
