Missouri Location Lindsay James Contact Service Lines Geology & Hydrogeology Project Summary Since 2001, Kansas City Fly Ash LLC (KCFA) and its predecessor, Lafarge, has received and used over 1.5 million tons of Coal Combustion Residuals (CCRs) produced at local electrical generating stations to stabilize portions of the former, Missouri Portland Cement underground mine. The beneficial use of CCRs is permitted and regulated at the Sugar Creek Mine Stabilization site by the MDNR and the City of Sugar Creek through a variety of beneficial reuse exemptions, operating permits, and local Special Use Permits (SUP). Services Provided In-Situ Vane Shear Testing One of the SUP regulatory requirements includes compressive strength testing to verify the material meets a 90-day compressive strength of 50 pounds per square inch (psi) in lab prepared cubes. In November 2014, Blackstone provided oversight and reporting for the in-situ vane shear testing of fly ash placed at the facility following ASTM D2573. In-situ vane shear testing was completed near two previously drilled and…
Missouri Location Lindsay James Contact Service Lines GroundwaterSolid Waste Geology & Hydrogeology Project Understanding Blackstone provides routine groundwater monitoring and compliance services for the City of St. Joseph Sanitary Landfill and the closed McArthur Drive Landfill. Blackstone has assisted the City with cell Construction Quality Assurance (CQA), Erosion Control Plan preparation, Cap and Closure services, installation of a nested perimeter probe gas monitoring system, landfill rate study, stormwater compliance, GCCS system repairs, and airspace calculations. Services Provided Blackstone provides routine semi-annual groundwater monitoring and statistical evaluation for the St. Joseph Sanitary Landfill and annual monitoring of groundwater, sediment, and surface water for the closed McArthur Drive Landfill. Non-routine groundwater services have included investigation of VOC detections in groundwater; preparation of sampling and analysis plans; background statistical updates; hydrogeological site characterization activities; investigation of fluctuating water levels in multiple monitoring wells using downhole camera inspection; and installation of replacement monitoring wells. Blackstone completed oversight and installation of a complex site-wide nested perimeter gas probe monitoring system…
Iowa, Kansas Location Emily Smart Contact Service Lines Due DiligenceGroundwater Geology & Hydrogeology Project Summary Blackstone provided pre-purchase review of environmental databases, imagery, site reconnaissance, soil and groundwater sampling, and geotechnical engineering exploration of Casey’s General Store properties ranging from active gas stations to agricultural fields. The objectives of the PPAs were to conduct site reconnaissance and data research for the site and adjacent properties to determine if any factors are present that may have a negative impact on the environmental integrity of the site; and to conduct a limited subsurface investigation (LSI) to determine if petroleum hydrocarbons have been released or spilled into the soils or groundwater underlying the site prior to the potential purchase by Casey’s General Stores. Geotechnical evaluation is also included in order to determine viability of soils for planned construction activities in order to predict project costs. Services Provided Site history and database review prior to mobilizationSite reconnaissanceMinimum one environmental boring per sitePID screening, log borehole, sample soil as appropriateSample…
