Materials Packaging Corp., Harrisonville, MO

Materials Packaging Corp. initiated remedial activities for two of the three existing stormwater outfalls monitored by the State of Missouri due to the stormwater effluent parameters established by the General Operating Permit being exceeded during the prior monitoring period. Habitat Architects worked with Materials Packaging Corp. to provide construction services for implementation and management of stormwater outfalls 001 and 003 at their Harrisonville, MO site. Habitat prepared a plan to manage total suspended solids, settleable solids, oil and grease and pH at each of the outfalls. The plan was implemented by Habitat during construction activities in May 2012. Construction activities included grading to construct a newly defined discharge channel, expansion of an existing stormwater treatment cell, placement of amended soil, installation of live plugs (vegetation), seeding, and erosion control.

FPE Floodplain Restoration Project USDA/ NRCS - Pemiscot County, MO

Habitat Architects staff worked with the United States Department of Agriculture Natural Resource Conservation Service (NRCS) while employed with Olsson Associates to design and oversee the construction of two floodplain restoration projects in Pemiscot County, Missouri. Design of the restoration project focused on re-establishing wetlands within each of the project sites through the detention of stormwater runoff and the implementation of new land-use practices. Design of the wetland restoration areas incorporated levees, earthen berms, habitat mounds, and excavation areas to restore the floodplain area to pre-impacted conditions while allowing ecological diversity across the sites. The design drawings and technical specifications were reviewed and approved by the NRCS prior to construction. Construction observation was completed bi-weekly and at key stages of the installation to track project progress, provide written documentation and photographs, review payment submittals from contractors, and to complete final site review for project completion.

Fort Hood Compost Facility Upgrades and Operations Fort Hood, TX

Habitat Architects staff worked with the U.S. Army Corps of Engineers, Tulsa District, and Ayuda Management Corporation while employed with Olsson Associates to design and implement improvements to the Fort Hood Composting Facility. The compost facility processes up to 2,000 cubic yards of petroleum contaminated soils and absorbent materials per year with the intention of reusing remediated soils as fill material. The project reviewed prior operations at the facility then re-engineered the composting process to focus on feedstock ratios intended to balance the amount of Petroleum, oil, and lubricant (POL)-impacted soils and absorbents in relation to wood chips, animal manure, and nutrient sources within each compost pile. The project also included the development of calculation sheets and guidance documents for use by Fort Hood staff to determine if additional nutrients (fertilizers) would be needed to bolster the petroleum degradation. Preliminary testing of the re-engineered process concluded that after 3-months TPH concentrations were reduced by 95% and after 5 months all gasoline and diesel range petroleum compounds were remediated from the materials.
